Method of modifying a bucket of a track loader and forming ditches with the modified track loader and apparatus therewith

Abstract

Trench digging and carrying with the same bucket attachment present on one track vehicle, the created dual functionality saves both time and expense by doing on-site what would normally be required to be done with two separate vehicles and additional manpower. The bucket attachment is especially advantageous when used in areas with limited space. Another advantage is that the modification can be adapted to bucket vehicles of various sizes.

Description

BACKGROUND

1. Technical Field

The present application relates to a bucket attachment for track vehicles used in agriculture and construction, which allows for a portion of the bucket to rotate downwards to be used for digging trenches or ditches.

2. Background Information

Background information is for informational purposes only and does not necessarily admit that subsequently mentioned information and publications are prior art.

The present application relates to a bucket attachment which has consists of two partitions, one of which can be rotated at an angle by means of a hydraulic cylinder to angle it in such a way that it can be used to create a ditch or trench.

Ditches and trenches are commonly used in agriculture and construction to create channels for water runoff or irrigation. Ditches or trenches are typically created with specialty equipment, known as a “trenchers.” which are made for the sole purpose of digging trenches, or by using a less specialized piece of equipment for moving earth, such as an excavator, which does not require the purchase of less specialized equipment but is more time-consuming and less effective.

Bucket attachments on track vehicles are considered very common and typically used for moving large quantities of earth or debris.

In at least one possible embodiment of the application, the modification of the bucket design allows for the bucket of the track loader to be used for digging trenches without additional specialized equipment while still being capable as function as a standard bucket would.

Object or Objects

An object of the present application is to provide the additional functionality of trench digging while maintaining the normal function of a bucket attachment for a track vehicle.

DESCRIPTION OF EMBODIMENT OR EMBODIMENTS

FIG. 1 is a diagram of a track loader vehicle 10. Although FIGS. 4 through 8 represent one possible arrangement of the present application on a track loader vehicle, it may also be embodied on other track vehicles, such as the skid steer vehicle illustrated in FIG. 2. The compact track loader includes a body frame 20, a hydraulic system 25, an engine 30, a cab 35, a pair of support arms or masts 40, a pair of attachment actuators 65, and a pair of track carriages or assemblies 70 (one on each of the opposite sides of the compact tract loader 10).

The engine drives one or more hydraulic pumps within the hydraulic system 25, and the pumps provide a flow of hydraulic fluid to the lift actuators 56, 65 and hydraulic drive systems to operate the track assemblies 70. The operator controls the hydraulic drive system 25, and therefore operates the compact track loader 10, with controls in the cab 35. In some embodiments, the controls move spool valves (not shown) to direct the hydraulic fluid to the lift actuators 55 and the attachment actuators 65. The support arms 40 are pivotably mounted to the body frame 20, the lift arms are pivotably mounted to the support arms 40, and an attachment interface is 75 is pivotally mounted to the lift arms 45. The lift actuators 65 are interconnected between the lift arms 45 and the body frame 20 and extend and retract in response to the operator's control of the hydraulic system 25 to cause the lift arms 45 to pivot in raising and lowering directions with respect to the support arms 40 and body frame 20. The support links 60 provide additional support and stability to the lift arms 45.

The attachment actuators 85 are interconnected between the lift arms 45 and the attachment interface 75, and extend and retract in response to the operator's control of the hydraulic system 25 to pivot the bucket 50 in curling and dumping directions with respect to the lift arms 45. Although the illustrated attachment is a bucket 50, the compact track loader may in other embodiments include attachments, including without limitation, augers, jack hammers, trenchers, grapples, rotary sweepers, saws, mixers, chippers, and backhoes. Other attachment actuators 65 may be used to raise, lower, tilt, or pivot the attachments for their intended purposes.

FIGS. 4 through 8 illustrate one present application, which is the bucket 50 of a compact track loader vehicle of which a portion of the left-most side 105 has been detached with a vertical cut and re-affixed with a hinge 110 in such a way that it allows the right-most portion of the bucket to rotate downwards. Although the tract pictured in FIGS. 4 through 8 illustrates the right-most side of the bucket being detachable, this modification may be added to the left, right, or both sides of the bucket. Additionally, anywhere from 10-40% of the bucket may be detached.

The hinge which connects the pieces of the bucket comprising of alternating knuckles which have been welded on to the edge of the floor of the bucket where the two pieces meet. A portion of the floor of the detached portion of the bucket has been removed so that the pieces can attach seamlessly, without adding any additional width to the bucket. The pin of the hinge is inserted through the knuckles to join the two pieces of the bucket, with the top of the pin slightly extruding from the edge of the floor of the bucket. A hydraulic cylinder 115 is attached to the back of the bucket, with the piston rod affixed to the detached portion of the bucket 106 and the body of the hydraulic cylinder attached to the intact portion of the bucket 100 in such a way that, when the piston rod of the hydraulic cylinder 115 extends, the detached portion of the bucket 105 rotates downwards at an angle for the purposes of digging a ditch, as seen in FIGS. 4 through 8. When the piston rod of the hydraulic cylinder 115 is not extended, the detached portion of the bucket 105 remains flush with the in-tact portion of the bucket 100, allowing the bucket to function as a conventional bucket would, as seen in FIG. 1.

FIG. 4 shows the front view of one possible use of the present invention attached to a track loader vehicle and the trench that it dug. The bucket of the track loader is comprised of two partitions, a detached partition 105 and a fixed partition 100. The detached partition of the bucket 105 in this particular drawing is 18 inches long and secured to the fixed partition by means of a steel hinge 110. The fixed partition Z2 in this particular drawing is 66 inches wide. A hydraulic cylinder 115 is attached to the detached and fixed partition. Although the invention pictured has the mobile partition on the leftmost side of the bucket, this modification may be added to the left, right, or both sides of the bucket. Additionally, the mobile partition may be anywhere from 10-40% of the entire length of the bucket.

FIG. 5 shows the bucket raised.

FIG. 6 shows the rear view of the same bucket. The hydraulic cylinder 115 is affixed to the top right edge of the stationary partition 125 by means of a bolt through a circular steel fixture welded onto the stationary partition and a bolt through a piece of steel welded onto the bottom right edge of the back of the mobile partition. When the piston rod of the hydraulic cylinder extends, the mobile partition is able to rotate between 0-35 degrees or greater relative to the floor of the stationary partition. The hydraulic cylinder connected to the hydraulic drive system of the track vehicle by at least one or two valves. The hydraulic cylinder could be controlled by a device such as, but not limited to, valve, lever, or button, inside the operator's cabin. The bucket is attached to the attachment interface of the track loader.

FIG. 7 shows the side of the bucket with the detached portion extended maximumly from the fixed portion.

FIG. 8 shows a top-down view of the embodiment in which the piston rod of the hydraulic cylinder is extended. The hinge 110 keeps the small section 105 attached to the large section 100 of the bucket 50. A portion of the floor of the bucket on the detached partition 100 has been cut out to allow for the knuckles of the hinge 105 to be added without adding extra width to the bucket.

Yet additionally, FIG. 8 illustrates when the hydraulic cylinder 115 is in the closed position, the bucket 50 can be used in ordinary use since the hinge 110 ensures the small section 105 is attached to the large section 100.

Further, FIG. 1 illustrates a compact track loader vehicle 10. Although the invention is illustrated as embodied in a compact track loader 10, it may also be embodied in other track vehicles. The compact track loader 10 includes a body frame 20, a hydraulic system 25, an engine 30, a cab 35, a pair of support arms or masts 40, a pair of lift arms 45, a bucket 50, a pair of lift actuators 55, a pair of support links 60, a pair of attachment actuators 65, and a pair of track carriages or track assemblies 70 (one on each of the opposite sides of the compact tract loader 10).

The engine 30 drives one or more hydraulic pumps within the hydraulic system 25, and the pumps provide a flow of hydraulic fluid to the lift actuators 55, 65 and hydraulic drive systems to operate the track assemblies 70. The operator controls the hydraulic drive system 25, and therefore operates the compact track loader 10, with controls in the cab 35. In some embodiments, the controls move spool valves (not shown) to direct the hydraulic fluid to the lift actuators 55 and the attachment actuators 65. The support arms or masts 40 are pivotably mounted to the body frame 20, the lift arms 45 are pivotably mounted to the support arms 40, and an attachment interface 76 is pivotably mounted to the lift arms 45.

The lift actuators 55 are interconnected between the lift arms 45 and the body frame 20 and extend and retract in response to the operator's control of the hydraulic system 25 to cause the lift arms 45 to pivot in raising and lowering directions with respect to the support arms 40 and body frame 20. The support links 60 provide additional support and stability to the lift arms 45.

The attachment actuators 65 are interconnected between the lift arms 45 and the attachment interface 76, and extend and retract in response to the operator's control of the hydraulic system 25 to pivot the bucket 50 in curling and dumping directions with respect to the lift arms 45. Although the illustrated attachment is a bucket 60, the Compact track loader may in other embodiments include other attachments, including without limitation, augers, jack hammers, trenchers, grapples, rotary sweepers, stump grinders, saws, concrete mixers, pumps, chippers, snow throwers, rotary cutters, and backhoes. With other attachment actuators 65 may be used to raise, lower, tilt, or pivot the attachments for their intended purposes.

Further, FIG. 2 illustrates a skid steer vehicle 80, wherein the invention may also be embodied within.

Further, FIG. 3 illustrates a prior art ditch digging machine 90.

Further, FIG. 4 illustrates a bucket 50, according to a first embodiment of the invention. The bucket 50 consists of a large section 100 and a small section 105 connected with a hinge 110 and a hydraulic cylinder 115. The entire bucket 50 extends beyond the track carriages 70 of the track loader vehicle 10. Along the front edge of the bucket 60 are sharp teeth 120 used to cut into the ground. The large section 100 of the bucket 50 includes six sharp teeth 120 while the small section 105 of the bucket 50 only includes one sharp tooth 120. Other embodiments may include more or less teeth along the front edge of the bucket 50. The single sharp tooth 120 of the small section 105 is used to create a ditch by cutting into the ground using only the small section 105 of the bucket 50. The hydraulic cylinder 115 is attached to the track loader vehicle 10 through a series of tubes 125 used to pump hydraulic fluid into and out of the hydraulic cylinder 115 to move the small section 105 of the bucket 50.

Additionally, FIG. 5 illustrates the connection between the small section 105 and the large section 100 of the bucket 50. The hinge 110 keeps the small section 105 attached to the large section 100, while the hydraulic cylinder 115 allows the small section 105 to be separated from the large section 100 in order to dig a ditch. The hydraulic cylinder 115 allows for the small section 105 to be lower about 30 degrees from the large section 100. The hydraulic cylinder 115 and hinge 110 can be adjusted to allow for a smaller or greater angle depending on the depth of ditch desired.

Additionally, FIG. 6 illustrates a back view of the hydraulic cylinder 115 attached to the bucket 50.

Yet further, FIG. 7 illustrates a side view of the hydraulic cylinder 115 attached to the bucket 50.

Yet additionally, FIG. 8 illustrates a front view of the hinge 110 used to keep the small section 105 attached to the large section 100 of the bucket 60. When the hydraulic cylinder 115 is in the closed position, the bucket 50 can be used in ordinary use since the hinge 110 ensures the small section 105 is attached to the large section 100.
