Patent Application
20160305082
The present disclosure generally relates to soil stabilization machines and, more particularly, to rotary mixers utilized in soil stabilization applications, and the like.
Soil stabilization is the process of mechanically or chemically improving the load-bearing capacity of soil or a ground surface. The process of soil stabilization may be required where roads are constructed for vehicular travel, as well as for building pads on which other construction may take place. In addition, soil stabilization may be useful in other applications, including surface mining, bio-remediation, agriculture and the building of high strength haul roads.
Stabilization machines, such as rotary mixers, typically include a frame quadrilaterally supported on traction units, an engine, an operator's station and a hood member under which a milling/mixing rotor is disposed, thereby forming an open bottom mixing chamber. A rotary mixer may be used as a soil stabilizer to cut, pulverize and mix native in-place soils with additive or alternatively additive and a fluid.
Some stabilization machines or rotary mixers may include an additive storage container to hold the dry additive and a fluid reservoir to hold fluid. Such stabilization machines further include an apparatus for spreading the dry additive and fluid directly onto the base material before the mixing rotor travels over the base material. However, as the built-in/mounted storage container and fluid reservoir each have limited volume capacity, numerous refilling operations of the container and fluid reservoir may be required during a single stabilization process. Alternatively, a dry additive storage truck and a fluid storage truck may directly supply the stabilization machine during operation with dry additive and fluid until the respective truck supply is depleted. Both such trucks have a much larger storage capacity than an additive storage container or fluid reservoir mounted on the frame of the stabilization machine.
Once the supply of the dry additive or fluid is depleted, a refill or new supply must be obtained from a supply truck. The supply truck must travel to the jobsite. A stabilization machine may be left waiting for the supply truck to arrive at the jobsite and locate the appropriate stabilization machine.
On jobsites, compactors are commonly used to compact to a desired density the surface area that has been worked by the stabilization machine. The number of passes of the stabilization machine over a given surface area, the mixing depth of the rotor of the stabilization machine and the moisture content of the resulting worked ground may impact the operation of the compactor to obtain the desired density.
On some jobsites and projects, multiple stabilization machines may work together to prepare adjacent or related portions of a surface area. It is often desirable to maintain consistency between the stabilization machines working different portions of a surface area with regard to the number of passes made, the mixing depth of the rotor and the moisture content of the resulting worked ground.
U.S. Pat. No. 7,489,993 issued Feb. 10, 2009 (the '993 Patent) discloses a vehicle fleet management information system that identifies location and direction of movement of each vehicle in a fleet and reports such information to a fleet manager. While beneficial, this system does not provide information to a supply truck on when the dry additive or fluid applied by a stabilization machine should be resupplied. A better system is needed.
In accordance with one aspect of the disclosure, a system is disclosed. The system may comprise a first stabilization machine and a supply truck. The first stabilization machine may include a first stabilization controller. The first stabilization controller may be configured to determine a resupply time for a dry additive or fluid that is applied by the first stabilization machine, and to transmit to a supply truck controller the resupply time and a current location of the first stabilization machine. The supply truck may be configured to transport the dry additive or the fluid. The supply truck may include a supply truck user interface and the supply truck controller. The supply truck controller may be in communication with the first stabilization controller and the supply truck user interface. The supply truck controller may be configured to display on the supply truck user interface the resupply time and the location.
In accordance with another aspect of the disclosure, a method of coordinating activities of a first rotary mixer in a system is disclosed. The system may include the first rotary mixer and a supply truck. The first rotary mixer may include a first stabilization controller. The supply truck may include a supply truck controller and a supply truck user interface. The supply truck controller may be in communication with the first stabilization controller and the supply truck user interface. The method may comprise: determining, by the first stabilization controller, a resupply time for a dry additive or a fluid that is applied by the first rotary mixer; transmitting, by the first stabilization controller, the resupply time and a current location of the first rotary mixer to the supply truck controller; and displaying the resupply time and the current location on the supply truck user interface.
In accordance with a further aspect of the disclosure, a system is disclosed. The system may comprise a first rotary mixer, a compactor and a second rotary mixer. The first rotary mixer may include a first stabilization controller. The first stabilization controller may be configured to determine for the first rotary mixer a resupply time for a dry additive or fluid that is applied by the first rotary mixer, a location of a worked surface area that has been worked by the first rotary mixer, a quantity of passes made in a portion of the worked surface area by the first rotary mixer, a mixing depth of the worked surface area and a moisture content of the worked surface area. The first stabilization controller may be further configured to transmit to a compactor controller and to a second stabilization controller the location of the worked surface area, the quantity of passes, the mixing depth, and the moisture content. The compactor may include a compactor user interface and the compactor controller. The compactor controller may be in communication with the compactor user interface and the first stabilization controller. The compactor controller may be configured to display on the compactor user interface the location of the worked surface area, the quantity of passes, the mixing depth and the moisture content. The second rotary mixer may include a stabilization user interface and the second stabilization controller. The second stabilization controller may be in communication with the stabilization user interface and the first stabilization controller. The second stabilization controller may be configured to display on the stabilization user interface the location of the worked surface area, the quantity of passes, the mixing depth and the moisture content.
Referring now to the drawings and with specific reference to
In one embodiment, the system 100 may comprise one or more stabilization machines 102 and one or more supply trucks 106 configured to transport dry additive or fluid. In another embodiment, the system 100 may comprise one or more stabilization machines 102 and one or more compactors 112. In yet another embodiment, the system 100 may comprise a first stabilization machine 102a, and a second stabilization machine 102b. Any of the above systems 100 may further include a site controller 108 and a site user interface 110. In other embodiments, the system 100 may include various combinations of the above. Other embodiments may include fewer or greater numbers of stabilization machines 102, fewer or greater numbers of supply trucks 106, fewer or greater numbers of compactors 112, more than one the site controller 108, and more than one site user interface 110. In some embodiments there may be no site controller 108 or site user interface 110.
One exemplary system 100 is shown in
In an embodiment, the stabilization machine 102 may be a rotary mixer 114. In an embodiment that includes multiple stabilization machines 102, the first stabilization machine 102a may be a first rotary mixer 114a and the second stabilization machine 102b may be a second rotary mixer 114b. Each stabilization machine 102 may further include a stabilization controller 160 and a stabilization user interface 162. While the description and drawings are made with reference to a stabilization machine 102 that is a rotary mixer 114, in other embodiments the stabilization machine(s) 102 may be any other type of machine used in road reclamation, soil stabilization, or surface pulverization.
The rotor 124 may include components rotationally driven by the engine 126 to pulverize a base material 128 of a ground surface 130 on which the rotary mixer 114 is operating. Ground surface 130 as used herein may include any base material 128 such as soil, dirt, gravel, sand, stones, concrete, pavement and the like. The rotor 124 may further include a plurality of cutting tools 132 spaced apart and pointed in a direction of rotation (indicated by an arrow 134) of the rotor 124, such that a tip end of each cutting tool 132 is driven into the base material 128 by the rotation of the rotor 124. As the rotary mixer 114 advances along the ground surface 130 to be stabilized, the rotor 124 and cutting tools 132 penetrate the ground surface 130 and lift the base material 128 from the ground surface 130, causing the base material 128 to move upwards into the mixing chamber 120, as indicated in
Allocations of dry additive 136 and fluid 138 may be introduced into the mixing chamber 120 where they collide with the upwardly moving base material 128. In this manner, the base material 128 is cut and pulverized within the mixing chamber 120, as well as immediately mixed with the dry additive 136 and fluid 138.
Dry additives 136 for soil stabilization may include fly ash, lime and/or cement, or the like. Fluids 138 may be water, oil, or like liquids. The addition of fluid 138 into the mixing chamber 120 may aid in the mixing process by wetting the pulverized base material 128 and the dry additive 136. The hood 122 of the mixing chamber 120 may provide a support for systems such as spray bars, nozzles or other fixtures by which dry additives 136 and fluid 138 may be delivered to the mixing chamber 120 and mixed with the base material 128. For example, spray bars supported on the hood 122 and extending the width of the mixing chamber 120 may deliver dry additives 136 and fluid 138 to the interior of the mixing chamber 120. Alternatively or in addition, a series of spaced nozzles or tubes may be disposed in the hood 122 to deliver dry additives 136 and fluid 138 to the interior of the mixing chamber 120.
As illustrated in
Several factors may influence the amount of dry additive 136 or fluid 138 to be delivered to the mixing chamber 120 and mixed with the base material 128, including: the initial characteristics of the ground surface 130 or the base material 128, the load-bearing capacity needed, the speed at which the rotary mixer 114 advances, the speed at which the rotor 124 rotates and the depth at which the rotor 124 engages the ground surface 130 (the “mixing depth 147”) (see
The metering devices 148, 150 for controlling/measuring the volume and rate of delivery of dry additive 136 and/or fluid 138 in the disclosed system 100 may include, but are not limited to, inlets, outlets, tubes, pumps, one or more rotary feeders, pressurized components, expandable components and/or one or more valves. Additionally, the metering devices 148, 150 contemplated herein may be automatically computer controlled based on the forward movement of the rotary mixer 114, on the rotation of the rotor 124 or on any other parameter such as the amount or gradation of the base material 128 estimated to exist in the mixing chamber 120 at any particular moment during operation. Alternatively, the metering devices 148, 150 may be controlled by an operator.
The supply truck 106 may be a dry additive storage truck 156 or a fluid storage truck 158. As noted earlier, embodiments of the system 100 may include a plurality of supply trucks 106. As such, embodiments of the system 100 may include a plurality of dry additive storage trucks 156 and a plurality of fluid storage trucks 158. The supply truck 106, for example the dry additive storage truck 156 or the fluid storage truck 158, may further include a supply truck controller 164 and a supply truck user interface 166. The fluid storage truck 158 may be a water storage truck, an oil storage struck, or the like. While the dry additive and fluid storage trucks 156, 158 of the present disclosure may be generally self-propelled and include a cab for a driver, dry additive and fluid storage trucks 156, 158 as disclosed herein also encompass non-self-propelled apparatus, for example, a truck chassis or trailer having a dry additive or fluid storage tank disposed thereon.
As noted previously, the resupply of dry additive 136 and fluid 138 to the rotary mixer 114 may occur after a storage container or fluid reservoir on the rotary mixer 114 is empty. Alternatively, in a scenario where a dry additive storage truck 156 and a fluid storage truck 158 may be connected to the rotary mixer 114 for continuously supplying the rotary mixer 114 (during operation) with dry additive 136 and fluid 138, resupply may occur when the dry additive storage truck 156 or fluid storage truck 158 supply is depleted or the content volume falls below a threshold.
As illustrated in
Fluid storage trucks 158 (for example, water storage trucks or oil storage trucks) are known in the art and may include various combinations of actuators, pumps and valves for delivering fluid 138.
Regarding dry additive 136 delivery from the dry additive storage truck 156 into the dry additive supply line 142 and ultimately to the rotary mixer 114, dry additives 136 may be fluidized and distributed using methods similar those of fluid distribution systems known in the art. Dry additive 136 delivery from the dry additive storage truck 156 and through dry additive supply line 142 may involve pressure manipulation through the use of air compressors, fans, suction fans or pump mechanisms. Blower/impeller systems having one or more blowers may also be employed in the presently disclosed system 100 and methods. In some embodiments, a metered amount of dry additive may be blown with a fan or compressed air system under the hood 122 and directly into the mixing chamber 120 after passing through the metering device 148 proximate to the mixing chamber 120. As with the metering of dry additive 136 and fluid 138 into the mixing chamber 120, delivery of the dry additive 136 and fluid 138 from the dry additive storage truck 156 and the fluid storage truck 158 to the dry additive supply line 142 and the fluid supply line 146, and ultimately to the mixing chamber 120, may be automatically computer controlled or controlled by an operator such that continuous delivery at a controlled rate and volume is maintained.

The navigation system 104 may be a Global Positioning System (GPS), a Global Navigation Satellite System (GNSS), or the like, as is known in the art for determining the location of a machine, such as the stabilization machine 102, the supply truck 106, and/or the compactor 112. The navigation system 104 may be configured to provide location data to the stabilization controller 160 for the stabilization machine 102. The location data may include the current location of the stabilization machine 102, and previous locations of the stabilization machine 102. Previous locations of the stabilization machine 102 may be utilized by the stabilization controller 160 to determine the location of the surface area worked by the stabilization machine 102 (the “worked surface area 154”) (

The stabilization controller 160 may be in operable communication via communication links 176 with the stabilization user interface 162. The supply truck controller 164 may be in operable communication via communication links 176 with the supply truck user interface 166. The compactor controller 168 may be in operable communication via communication links 176 with the compactor user interface 170. The site controller 108 may be in operable communication via communication links 176 with the site user interface 110. Each user interface 110, 162, 166, 170 may be configured to be an input/output device, and may include a display screen.
The communication link 176 may be hardware and/or software that enables the transmission and receipt of data messages through a data link or a wireless communication link. The wireless communication link may include, for example, satellite, radio (voice and/or data), cellular, infrared, Ethernet, and the like.
The processor 172 may be a microprocessor or other processor as known in the art. The processor 172 may execute instructions and generate control signals for determining the time at which a new supply of dry additive 136 or fluid 138 will be needed by the stabilization machine 102, the location and/or boundaries of the surface area worked by the stabilization machine 102, the quantity of passes in such surface area, the mixing depth and the moisture content. Such instructions may be read into or incorporated into a computer readable medium, such as the memory component 174 or provided external to the processor 172. In alternative embodiments, hard wired circuitry may be used in place of, or in combination with, software instructions to implement a control method.
The term “computer readable medium” as used herein refers to any non-transitory medium or combination of media that participates in providing instructions to the processor 172 for execution. Such a medium may comprise all computer readable media except for a transitory, propagating signal. Forms of computer-readable media may include any medium from which a computer processor 172 can read.
The each controller 108, 160, 164, 168 is not limited to one processor 172 and memory component 174. Each controller 108, 160, 164, 168 may be several processors 172 and memory components 174.
Each stabilization controller 160 may be disposed on a stabilization machine 102, for example on a rotary mixer 114.

The stabilization controller 160 may be further configured to receive metering information from the metering devices 148, 150. The metering information may include the volume delivered and the rate of delivery of dry additive 136 and/or fluid 138 by the stabilization machine 102. Based on this metering information, the stabilization controller 160 may, in some embodiments, calculate the amount of fluid 138 or dry additive 136 remaining in on-board storage container, on-board fluid reservoir, or in the respective supply truck 106. The stabilization controller 160 may be configured to calculate the time (the “resupply time”) at which a new supply of dry additive 136 or fluid 138 will be needed by the rotary mixer 114 given the volume delivered (applied by the stabilization machine 102) and the rate of delivery. In some embodiments, the stabilization controller 160 may calculate the remaining time period (for example, minutes, seconds, etc.) until a new supply of dry additive 136 or fluid 138 will be needed based on the current rate of delivery of the respective dry additive 136 or fluid 138. In addition, the stabilization controller 160 may also be configured to determine the mixing depth 147 and the moisture content of the base material 128 of the worked surface area 154.
The stabilization controller 160 may be configured to transmit to one or more supply truck controllers 164 and/or one or more site controllers 108 the current location of the stabilization machine 102 (in this case, a rotary mixer 114), and the resupply time or the remaining time period until resupply is desired.
