To harvest crops, farmers typically utilize large agricultural vehicles, such as combines, tractors, and trailers. However, trailers are typically not properly equipped for over soil travel. This leads to an increase in soil compaction. Soil compaction reduces crop yield through poor water and nutrient intake.
Thus, there is a need for improvement in this field.
A unique crop harvesting system including a vehicle and a trailer has been developed to reduce soil compaction. In one embodiment, the vehicle includes a standard wheel and tire arrangement. In another embodiment, the vehicle includes a continuous track propulsion system. The continuous track system distributes a vehicle weight over an increased surface area. As should be appreciated, distributing the vehicle weight reduces soil compaction. The vehicle further includes a hitch configured to receive a trailer. In one aspect, the hitch is a fifth wheel type hitch. In another aspect, the trailer is a standard semi-trailer. In a further aspect, the trailer is a hopper type trailer.
The fifth wheel hitch is configured to distribute a trailer load weight evenly onto the vehicle to decrease compaction. The hitch includes an automatic actuator to hook and drop the trailer from the vehicle. In one example, the hitch further includes one or more sensors. The sensors are configured to monitor the hook and drop process to confirm completion. The trailer includes modified automatic landing gear. The landing gear is configured to extend when uncoupled from a vehicle and retract when coupled to a vehicle. In one embodiment, the landing gear is configured with a large landing foot. The large landing foot increases surface area to decrease soil compaction. The trailer braking system is self-contained. Meaning, the trailer braking system is not connected to the braking system of the vehicle. In one example, the trailer braking system includes an air tank, an electric pump, a battery, and a solenoid valve. The solenoid valve is configured to control a parking brake release through wireless communication with the vehicle. The wireless communication is a short-range wireless communication protocol. In one example, the wireless communication protocol is Bluetooth. The trailer braking system is configured to activate when the landing gear is extended to prevent activation on the road. In one example, the trailer includes Department of Transportation (DOT) approved high-flotation tires and a central tire inflation system (CTIS). The CTIS allows the tires to be deflated when on soil to mitigate compaction and inflated when on the road to minimize friction and increase fuel savings.
In some examples, a wireless network is configured to control various aspects of the vehicle and trailer. For example, the wireless network is configured to control the operation of a tarp covering the trailer. In another example, the wireless network is configured to transmit a video feed of the trailer to an operator. In a further example, the wireless network is configured to control trailer lighting. In yet another example, the wireless network is configured to send trailer position data to the vehicle from Global Positioning System (GPS) components located on the trailer. The position data from the trailer is used by the vehicle to facilitate an automated process whereby the vehicle drops off a loaded trailer, connects to the wireless network of an empty trailer, and uses the position data to properly hook and remove an empty trailer.
In one example, the vehicle is attached to a combine with a tow arm and towed to the field. In a second example, the tow arm includes one or more sensors. The sensors direct the vehicle to follow the path of the combine under the power of the vehicle. Once the operator has reached the crop area, the vehicle is disconnected from the tow arm and the tow arm is stowed under the vehicle. To facilitate communication, the vehicle is connected to the combine wirelessly via a dongle connected to an International Organization for Standardization (ISO) bus/diagnostic port of the combine. The wireless connection is configured to exchange information about the harvested area, the current yield, and the remaining storage space inside the combine. In one example, the wireless connection is a long-range wireless network.
As the combine reaches storage capacity, the vehicle moves into position to accept a load from the combine. As the vehicle moves to intercept the combine, the tarp over the trailer automatically opens to receive the load. Once the vehicle is properly positioned, a command is sent to the combine. The command instructs the combine to empty the crop storage into the trailer. In one form, the combine uses on-the-go dumping in which the combine continues harvesting during the loading or unloading process. For example, an auger arm of the combine swings out over the vehicle while the combine continues to harvest. During the loading process, the vehicle shifts to allow for loading towards the front of the trailer first. The shifting process keeps weight over the tracks and/or wheels of the vehicle to aid in traction control. In one embodiment, the trailer includes one or more load sensors in the suspension. In another embodiment, the trailer includes one or more load sensors in the fifth wheel hitch. The load sensors are configured to monitor the weight of the crops that are loaded into the trailer. The weight data is used to adjust the position of the vehicle. As was discussed above, the position of the vehicle is based upon balancing the trailer weight. In another example, the trailer further includes one or more paddle sensors. The paddle sensors are configured to monitor the height of the crops in the trailer. In one example, the sensors send an alert to the vehicle that the crops have reached a predetermined fill level.
After the trailer is filled, the vehicle transmits a command to the combine to stop loading, pull away, and resume harvesting. If the trailer is full, the vehicle returns to a loading area. As the vehicle moves towards the loading area, the trailer begins to automatically close the tarp to protect the crops. Once the vehicle reaches the loading area, the vehicle activates the landing gear of the trailer, activates the parking brakes of the trailer, and automatically disconnects from the trailer.
In another embodiment, the crop harvesting system includes a vehicle, commonly referred to as a mule, detachably coupled to the trailer. In one example, the trailer is an on-road compatible semi-trailer with a pivotable rear door for crop unloading. In another example, the trailer includes a dump hoist. The mule is configured to lift and fully support the weight of the trailer to prevent trailer ground contact. Most semi-trailers and other road-based trailers are not designed for travelling across farm fields. The wheels of the trailer can compact the soil and even become stuck in mud. By lifting and carrying the trailer across the farm field to combine, the vehicle or mule can avoid these as well as other issues.
In one example, the mule is an autonomous vehicle including a trailer support system. The trailer support system is configured to slide underneath the trailer during pickup guided by one or more sensors, channels, and/or rollers. In another example, the trailer includes automatic landing gear and/or automatically retracting wheels. To facilitate trailer drop-off and pick-up, the landing gear is configured automatically extend and retract upon detection of the mule. For example, during trailer pickup, the landing gear detects the approaching mule and automatically retracts underneath the trailer. In another example, the landing gear is configured to automatically retract after the trailer latches into a fifth wheel hitch on the mule. Retracting the landing gear clears space to allow the mule to continue to back further under the trailer. For example, as the mule backs under the trailer one or more trailer lift arms of the mule engage one or more rails of the trailer to guide the trailer onto the mule. Simultaneously, the fifth wheel hitch slides along one or more trailer guides via casters. In one embodiment, once the mule reaches the trailer wheels, the mule locks into the trailer and the trailer wheels are retracted. As should be appreciated, after the trailer wheels are retracted the trailer is fully supported by the mule. In another embodiment, once the mule reaches the trailer wheels, the mule pivots such that the trailer wheels are raised above the ground. Put differently, the trailer is said to be “floating” (e.g. not in contact with the ground) to reduce soil compaction.
In one example, the mule is configured to carry the trailer into the field to collect crops from the combine. In another example, the mule is configured to pick-up and empty trailers that have already been filled and are deposited at a “dump depot.” The trailer includes one or more load sensors configured to monitor the weight of the crops that are loaded into the trailer. The weight data is used to adjust the position of the mule. The position of the mule is based upon balancing the trailer weight. In another example, the trailer further includes one or more moisture sensors. The moisture sensors are configured to monitor the moisture content of the harvested crops. In one example, the moisture content and crop weight are used to calculate an expected crop yield.
After the trailer is full, the mule pulls away from the combine and drives to an unloading area. As the mule drives to the unloading area, an automatic tarp is deployed to “seal” the crop load. In one example, the trailer includes one or more sensors located on the tarp and/or trailer rear door. The one or more sensors are configured to detect the position of the tarp and/or rear door. In another example, the one or more sensors are configured to detect tampering with the crop load.
In one embodiment, once arriving in the unloading area, the mule extends the trailer wheels, unlocks from the trailer, and drives out from underneath the trailer. As the mule drives out from underneath the trailer the landing gear is automatically extended. To enable trailer locating tracking, the trailer includes a Global Positioning System (GPS) configured to monitor the status and location of the trailer. In another embodiment, the mule includes a hitch with one or more attachment arms. In one example, the hitch is configured to connect with a grain bagger. For example, the mule is configured to automatically connect with the grain bagger and begin to transfer grain from the trailer into the grain bagger via a conveyor system within the mule.

The language used in the claims and specification is to only have its plain and ordinary meaning, except as explicitly defined below. The words in these definitions are to only have their plain and ordinary meaning. Such plain and ordinary meaning is inclusive of all consistent dictionary definitions from the most recently published Webster's dictionaries and Random House dictionaries. As used in the specification and claims, the following definitions apply to these terms and common variations thereof identified below.
“About” with reference to numerical values generally refers to plus or minus 10% of the stated value. For example, if the stated value is 4.375, then use of the term “about 4.375” generally means a range between 3.9375 and 4.8125.
“And/Or” generally refers to a grammatical conjunction indicating that one or more of the cases it connects may occur. For instance, it can indicate that either or both of two stated cases can occur. In general, “and/or” includes any combination of the listed collection. For example, “X, Y, and/or Z” encompasses: any one letter individually (e.g., {X}, {Y}, {Z}); any combination of two of the letters (e.g., {X, Y}, {X, Z}, {Y, Z}); and all three letters (e.g., {X, Y, Z}). Such combinations may include other unlisted elements as well.
“Brake” generally refers to a device for arresting and/or preventing the motion of a mechanism usually via friction, electromagnetic, and/or other forces. Brakes for example can include equipment in automobiles, bicycles, or other vehicles that are used to slow down and/or stop the vehicle. In other words, a brake is a mechanical device that inhibits motion by absorbing energy from a moving system. The brake can be for example used for slowing or stopping a moving vehicle, wheel, and/or axle, or to prevent its motion. Most often, this is accomplished by friction. Types of brakes include frictional, pressure, and/or electromagnetic type braking systems. Frictional brakes for instance can include caliper, drum, and/or disc drakes. Electromagnetic braking systems for example can include electrical motor/generators found in regenerative braking systems.
“Cellular Device” generally refers to a device which sends or receives data, and/or sends or receives telephone calls using a cellular network. Cellular devices may thus be characterized as nodes in a communications link operating as an originating and/or final receiving node. A cellular device transmits to and receives from a cellular transceiver located in the cell (e.g. at a base unit or “cell tower.”) Radio waves are generally used to transfer signals to and from the cellular device on a frequency that is specific (but not necessarily unique) to each cell. A cellular device may include a computer with memory, processor, display device, input/output devices, and so forth, and thus may be used as, and referred to as, a personal computing device.
“Class 8 Trailer” means, per the U.S. Department of Transportation Heavy Duty Classification, a trailer or trailers pulled behind a truck wherein the gross vehicle weight rating is above 33,000 pounds (14,969 kg).
“Combine” generally refers to a harvesting machine that heads, threshes, and/or cleans grain while moving over a field.
“Computer” generally refers to any computing device configured to compute a result from any number of input values or variables. A computer may include a processor for performing calculations to process input or output. A computer may include a memory for storing values to be processed by the processor, or for storing the results of previous processing. A computer may also be configured to accept input and output from a wide array of input and output devices for receiving or sending values. Such devices include other computers, keyboards, mice, visual displays, printers, industrial equipment, and systems or machinery of all types and sizes. For example, a computer can control a network interface to perform various network communications upon request. A computer may be a single, physical, computing device such as a desktop computer, a laptop computer, or may be composed of multiple devices of the same type such as a group of servers operating as one device in a networked cluster, or a heterogeneous combination of different computing devices operating as one computer and linked together by a communication network. A computer may include one or more physical processors or other computing devices or circuitry, and may also include any suitable type of memory. A computer may also be a virtual computing platform having an unknown or fluctuating number of physical processors and memories or memory devices. A computer may thus be physically located in one geographical location or physically spread across several widely scattered locations with multiple processors linked together by a communication network to operate as a single computer. The concept of “computer” and “processor” within a computer or computing device also encompasses any such processor or computing device serving to make calculations or comparisons as part of a disclosed system. Processing operations related to threshold comparisons, rules comparisons, calculations, and the like occurring in a computer may occur, for example, on separate servers, the same server with separate processors, or on a virtual computing environment having an unknown number of physical processors as described above.
“Conveyor” is used in a broad sense to generally refer to a mechanism that is used to transport something, like an item, box, container, and/or SKU. By way of non-limiting examples, the conveyor can include belt conveyors, wire mesh conveyors, chain conveyors, electric track conveyors, roller conveyors, cross-belt conveyors, vibrating conveyors, and skate wheel conveyors, to name just a few. The conveyor all or in part can be powered or unpowered. For instance, sections of the conveyors can include gravity feed sections.
“Couple” or “Coupled” generally refers to an indirect and/or direct connection between the identified elements, components, and/or objects. Often the manner of the coupling will be related specifically to the manner in which the two coupled elements interact.
“Fifth-Wheel Coupling” generally refers to a horse-shaped device on a towing vehicle, such as a tractor or truck, that is configured to receive a kingpin on a trailer, such as a semitrailer or camper trailer, so as to provide a mechanical link between the towing vehicle and the trailer. For example, some camper trailers use a fifth-wheel configuration, requiring the fifth-wheel coupling to be installed in the bed of a pickup truck. As the connected truck turns, the downward-facing surface of the trailer with the kingpin at the center rotates against an upward-facing surface of the fixed fifth wheel coupling that does not rotate. To reduce friction, grease is sometimes applied to this surface of the fifth wheel coupling. This fifth-wheel configuration is sometimes called a turn-table in Australia and New Zealand. Typically, but not always, the fifth-wheel coupling is located directly above an axle or between the axles of a vehicle.
“Flat” generally refers to an object having a broad level surface but with little height.
“Frame” generally refers to a structure that forms part of an object and gives strength and/or shape to the object.
“Guidance, Navigation, and Control (GNC) System” generally refers to a physical device, a virtual device, and/or a group of devices configured to control the movement of vehicles, such as automobiles, automated guided vehicles, ships, aircraft, drones, spacecraft, and/or other moving objects. GNC systems are typically configured to determine a desired path of travel or trajectory of the vehicle from the vehicle's current location to a designated target, as well as desired changes in velocity, rotation, and/or acceleration for following the path. The GNC system can include and/or communicate with sensors like compasses, GPS receivers, Loran-C, star trackers, inertial measurement units, altimeters, environmental sensors, and the like. At a given time, such as when the vehicle is travelling, the GNC system is configured to determine the location (in one, two, or three dimensions) and velocity of the vehicle. For example, the GNC system is able to calculate changes in position, velocity, attitude, and/or rotation rates of a moving vehicle required to follow a certain trajectory and/or attitude profile based on information about the state of motion of the vehicle. The GNC system is able to maintain or change movement of the vehicle by manipulating forces by way of vehicle actuators, such as steering mechanisms, thrusters, flaps, etc., to guide the vehicle while maintaining vehicle stability. GNC systems can be found in autonomous or semi-autonomous vehicles.
“Remote” generally refers to any physical, logical, or other separation between two things. The separation may be relatively large, such as thousands or millions of miles or kilometers, or small such as nanometers or millionths of an inch. Two things “remote” from one another may also be logically or physically coupled or connected together.
“Satellite Navigation” generally refers to a system that uses satellites to provide geo-spatial positioning data. In one example, the system may include a receiver that interacts with satellites using electromagnetic radiation. The timing of the transmission of the signal from the receiver to the satellites allows calculation of the position of the receiver using triangulation. Some of examples of satellite navigation systems include global positioning systems such as GPS and GLONASS as well as global positioning systems under development such as Galileo. A satellite navigation system may also be a regional positioning system such as BeiDou, NAVIC, and QZSS.
“Sensor” generally refers to an object whose purpose is to detect events and/or changes in the environment of the sensor, and then provide a corresponding output. Sensors include transducers that provide various types of output, such as electrical and/or optical signals. By way of nonlimiting examples, the sensors can include pressure sensors, ultrasonic sensors, humidity sensors, gas sensors, motion sensors, acceleration sensors, displacement sensors, force sensors, optical sensors, and/or electromagnetic sensors. In some examples, the sensors include barcode readers, RFID readers, and/or vision systems.

“Storage Container” generally refers to an object that can be used to hold or transport SKUs or other objects. By way of non-limiting examples, the storage container can include cartons, totes, pallets, bags, and/or boxes.
“Substantially” generally refers to the degree by which a quantitative representation may vary from a stated reference without resulting in an essential change of the basic function of the subject matter at issue. The term “substantially” is utilized herein to represent the inherent degree of uncertainty that may be attributed to any quantitative comparison, value, measurement, and/or other representation.
“Tow Coupler” or “Trailer Coupler” generally refers to a device used to secure a trailer, a towed vehicle, and/or other towed object to a towing vehicle. Typically, but not always, the trailer coupler is coupled to a hitch of the towing vehicle. For example, the trailer coupler can be configured to couple to a hitch ball. Common types of trailer couplers include (but are not limited to) straight tongue couplers, A-frame couplers, adjustable couplers, and fifth wheel-gooseneck couplers. The trailer coupler can include any number of mounting styles. By way of non-limiting examples, the mounting styles can include straight channel, foldaway, round tongue, A-frame, flat mount, adjustable tongue, lunette ring, gooseneck, trigger, thumb, wrap around yoke, and pin mounting styles or mechanisms. The trailer coupler in some instances can further include a trailer jack for lifting the trailer coupler to the proper height for coupling to the hitch.
“Tow Hitch”, “Trailer Hitch”, or “Hitch” generally refers to a device attached to a chassis of a vehicle for towing another object, such as a trailer, aircraft, wagon, and/or another vehicle, to name just a few examples. Tow hitches are commonly mounted with bolts or other fasteners to the chassis, but in other examples, the tow hitch can be integrally formed with the chassis and/or attached in other ways such as via welding. Typically, but not always, the trailer hitch is coupled to a trailer coupler that is secured to the towed object. There are a number of types of tow hitches. For example, the tow hitch can include receiver type and fixed drawbar type hitches. Receiver type hitches can include a receiver mounted to the chassis and a removable mount that is connected to the receiver. In one form, the receiver is in the form of a receiver tube that defines a receiver opening in which the removable mount is mounted, such as via a bolt or other fastener, and/or otherwise connected. The removable mount can for example include one or more ball mounts, hitch bike racks, cargo carriers, and/or other hitch mounted accessories. Fixed drawbar type hitches are typically, but not always, built as a unitary piece that is mounted to the chassis. The fixed drawbar type hitch normally includes one or more holes for a trailer ball or other mounts. The trailer mounts can for instance take the form of a tow ball to allow swiveling and articulation of a trailer; a knuckle coupling; a tow pin or a tow hook with a trailer loop coupling; and/or a pintle and lunette ring coupling. The tow hitches can for instance include Society of Automotive Engineers (SAE) class I, II, III, IV, and V hitches.
“Trailer” generally refers to an unpowered vehicle towed by another vehicle. For instance, a trailer can include a nonautomotive vehicle designed to be hauled by road, such as a vehicle configured to transport cargo, to serve as a temporary (or permanent) dwelling, and/or acting as a temporary place of business. Some non-limiting examples of trailers include open carts, semi-trailers, boat trailers, and mobile homes, to name a just few. Typically, trailers lack a power train for propelling themselves over long distances and require another powered vehicle to move them. However, trailers may include a power source, such as a battery or generator, for powering auxiliary equipment.
“Truck” means a powered truck (also known as a tractor or cab) for pulling one or more trailer(s).
“Vehicle” generally refers to a machine that transports people and/or cargo. Common vehicle types can include land-based vehicles, amphibious vehicles, watercraft, aircraft, and space craft. By way of non-limiting examples, land-based vehicles can include wagons, carts, scooters, bicycles, motorcycles, automobiles, buses, trucks, semi-trailers, trains, trolleys, and trams. Amphibious vehicles can for example include hovercraft and duck boats, and watercraft can include ships, boats, and submarines, to name just a few examples. Common forms of aircraft include airplanes, helicopters, autogiros, and balloons, and spacecraft for instance can include rockets and rocket powered aircraft. The vehicle can have numerous types of power sources. For instance, the vehicle can be powered via human propulsion, electrically powered, powered via chemical combustion, nuclear powered, and/or solar powered. The direction, velocity, and operation of the vehicle can be human controlled, autonomously controlled, and/or semi-autonomously controlled. Examples of autonomously or semi-autonomously controlled vehicles include Automated Guided Vehicles (AGVs) and drones.
“Wall” means here is structure that forms a solid surface. It may be a portion of a house, room, or otherwise. A wall may be planar or multiplanar and may be constructed of any of a variety of materials, including, but not limited to metal, concrete, wood, or plastic.
It should be noted that the singular forms “a,” “an,” “the,” and the like as used in the description and/or the claims include the plural forms unless expressly discussed otherwise. For example, if the specification and/or claims refer to “a device” or “the device”, it includes one or more of such devices.
It should be noted that directional terms, such as “up,” “down,” “top,” “bottom,” “lateral,” “longitudinal,” “radial,” “circumferential,” “horizontal,” “vertical,” etc., are used herein solely for the convenience of the reader in order to aid in the reader's understanding of the illustrated embodiments, and it is not the intent that the use of these directional terms in any manner limit the described, illustrated, and/or claimed features to a specific direction and/or orientation.
