Abstract

A demolition and compaction track shoe and assembly for a crawler vehicle includes a central opening (21) and downwardly protruding diagonally oriented demolition blades (28,29) cooperating with transversely oriented grouser blades (22,23). The demolition blades provide support to the shoe intermediate the grouser blades to thereby give a smoother ride. The central opening allows material compacted behind the shoe to escape and channels between the grouser and demolition blades allow such material to discharged from the shoe during the non-ground-engaging part of the track cycle. The invention has application to land fill operations and in agriculture where stubble is to be broken up prior to discing.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a crawler type vehicle, and in particular to a periodic track set of said vehicle useful for destroying and compacting landfill materials such as soil, waste, solid waste debris, etc. Concerning solids.

BACKGROUND OF THE INVENTION Traditionally, vehicles with special tamping legs have been used to compact landfills, dumps, and construction sites. Track tractors with tracks designed only for traction are also used for this purpose.

Problems to be Solved by the Invention Such vehicles have certain limitations. For example, these vehicles have difficulty effectively destroying large rocks and pieces of concrete that may be encountered on construction sites. Also, when conventional track tractors are used to tamp down "wet" material, the wet material is tamped behind the track shoe and tightens the track.

In addition, when compacting landfill materials such as waste and soil, waste materials that have been broken down and reduced in size during compaction may be compacted into the ground prior to compaction of the waste material or during compaction. It turns out that it is even more effective if it can be done.

In addition, when corn stumps are left in the field after harvest, wheeled compactors are limited in their ability to crush the stumps before flattening them to the ground. Burning stumps is prohibited in many areas, so stumps must be flattened on the ground.

A crawler-type vehicle with track shoes or pads as described herein assists in breaking up stumps more completely than when discs alone are used.

Thus, there is a need for improved compaction equipment for use in landfills and waste transfer stations and construction and demolition sites.

SUMMARY OF THE INVENTION Generally, there is provided a breaking tamping track shoe and assembly thereof for a tracked tractor vehicle, wherein the track is characterized by a rigid shoe structure having a pair of cutting blades and a pair of breaking blades. do. The cutting blade is positioned substantially perpendicular to the path of the track as well as to the underside of the shoe. The breaking blade is positioned substantially perpendicular to the underside of the shoe but at a significant angle to the path. The breaking and cutting blades provide an escape gap to allow the material to exit the back of the shoe through a central opening and escape freely from the tread as well as from the underside of the shoe, thereby keeping the track clean. are arranged around the central opening so as to constitute a Thus, the cutting blades both extend only halfway across the width of the shoe and are staggered on either side of the centerline of the orbital path, while the breaking blade is positioned in a spaced apart relationship to the cutting blade. in this way,
The fill material is pushed out not only from the tread but also from the area behind the shoe. The above action helps to prevent harmful build-up of fill material on the back side of the shoe.

In general, it is an object of the present invention to provide an improved compaction vehicle whose treads reduce the amount of landfill material (e.g., concrete blocks, solid waste, etc.) and then crush these materials into the ground. be.

Another purpose of the present invention is to "run without dirt".
In other words, it is an object of the present invention to provide a tamping vehicle having a crawler type track that runs substantially free of closely packed fill material behind or on the tread surface.

Another object of the invention is to provide a method for compacting a landfill.

Yet another object of the present invention is to provide an improved crawler type track that increases the stability and smoothness of operation of a tamping vehicle.

These and other objects of the invention will become readily apparent from the following detailed description of the preferred embodiments when considered in conjunction with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A tracked vehicle 10 used for compacting landfill materials such as soil and waste comprises a pair of spaced apart parallel track assemblies 11, 12, shown in detail in FIGS. 1 and 7. It is equipped with Track assembly 1
1 and 12 are a plurality of articulated links 1 connected in tandem to form an infinite or periodic "belt".
It has 3. Link 13 supports a track shoe 14 secured thereto by bolts 16.

The vehicle 10 uses its tracks to destroy or compact reclaimed materials such as soil, waste, rocks, garbage, and the like.

Each track shoe 14 has a rectangular rigid plate 17
Consisting of For purposes of illustration, the plate 17 has an upper surface 18 and a lower surface 19 (FIGS. 4 and 5).

The term "underside" used here refers to the
When the 0 moves, it hits a surface that acts as a tread that engages the ground. However, it will be seen that when the lower surface 19 is reversed (as in FIGS. 4 and 5), it becomes the "upper surface" for a significant portion of its periodic travel.

A relief opening 21 in the form of a relatively large trapezoidal opening passes through the shoe 14 in the center. The opening 21 is large enough to allow fill material to easily escape outwardly through the opening so that the tamped material does not collect after the show 14.

For example, as shown in FIG. 5, the leading or left side edge 19b is curved slightly downward to slide under the trailing edge 19c of the leading shoe 14 in the track assembly 11. There is. The leading edge region portions 24 of the plates 17 serve to create an enclosure between shoes arranged in tandem along the track assembly 11. Therefore, when the shoes 14 travel on a horizontal course of their path, the leading edge area portion 24 will be located below the trailing edge 19c of the preceding shoe 14. The remainder of the underside of shoe 14 provides a significant area for ground engagement, referred to as the tread surface. Thus, as shown in FIG. 4, the area within X and Y is the tread surface.

A drive sprocket 44 engages link pin 46 to move the track assembly. Sprocket tooth 4
4a is aligned to pass directly beneath the opening 21 so that the sprocket teeth can assist in forcing the tamped material out of the opening 21.

As the shoes 14 travel at the ends of their periodic paths, the edges 19b, 19c of adjacent shoes move to open and close the gap between them. This action, together with the action of drive sprocket 44, forces the tamped material outwardly from opening 21.

a pair of cutting blades 22 on the lower surface of the shoe 14;
23 protrudes perpendicularly to the tread surface, and the tread surface X, Y
The shoe 14 extends laterally along a significant portion of the lateral leading edge region 26 and lateral trailing edge region 27 of the shoe 14, respectively. The cutting blades 22, 23 are laterally staggered on either side of the centerline of the path of travel of the track shoe 14 for the following reasons.

Further, the lower surface 19 has a pair of breaking blades 28,2.
9, and these blades also protrude perpendicularly to the areas of the treads X, Y.
9 are in substantially parallel relationship leading edge region 26,
extending diagonally from the trailing edge area 31 towards the trailing edge area 31 and towards the leading edge area 26 respectively, which destroys the waste while allowing the tamped material emerging from the opening 21 to leave the track freely. It's for a reason.

The cutting blade 22 is located at the front edge 21a of the opening 11.
and a tapered piece 22a which serves to strengthen the plate 17 in the area of the opening for the bolt 32 (not shown). Thus, the parts of plate 17 adjacent to the bolt holes and elongated edge 21a are the weakest parts. This weakening of the front part of the plate 17 is a tapered piece 22a.
is strengthened by.

Both cutting blades 22 and 23 are connected to the shoe 14
, extending only partway through the full width Y, and staggered to either side of the center line of the path of its associated trajectory. Each portion 33, 34 (FIG. 4) between the side edges 36, 37 of the rigid plate and the lateral inner ends of the cutting blades 22, 23 is a breaking blade that intersects the lateral inner ends of the cutting blades and the plane of the cutting blades. There are gaps 38 and 39 between them, respectively. Gaps 38, 39 serve to guide waste 42 out of the shed 14. Additional gaps or grooves for waste are indicated at 38' and 39'. Destruction blade 2
8, 29 are primarily located after one of the gaps 38, 39 in the path of the passing landfill material 42.

Assuming that the track shoe 14 that moves up and down in the direction of arrow 43 when the vehicle moves forward, that is, when the track assembly is viewed from the rear, is shown in FIG. The tightly packed waste 42 is removed from the drive sprocket 44.
Loosening occurs not only due to the movement of the shoe 14, but also due to the relative movement of the shoe 14 as it moves around the ends of its periodic path.

When the shoe 14 moves upward, the gaps 39, 3
9' allows the loose waste 42 to freely escape from the shoe 14 under its own weight. The gaps 39, 39' perform this function when the tracks move in the opposite direction.

Thus, as mentioned above, this track is designed to run clean, removing waste and other landfill materials fairly quickly. The use of crawler-type tracks for crushing compaction vehicles further enhances this feature as the shoes are pulled apart as they pass around the ends of the track. This trajectory allows things to escape like this. This "orbital rift" between successive shots
A slot is formed between the shoes to allow the waste that has entered to fall out. By reducing the size of the material before crushing it and forcing it into the ground, the above-described vehicle accomplishes compaction with a technique that differs substantially from conventional techniques.

It has been found that a track shoe 14 of the type described above improves and increases safety and also serves to smooth out the running. The track shoe 14 therefore has a shoe 14 in the area extending between the cutting blades 22, 23.
It includes means projecting from the plate 17 to form a substantially continuous support underneath the plate 17. Thus, each tread is continuously supported from cutting blade 22 to cutting blade 23 as it progressively engages the ground.

As best shown in Figures 1 to 3,
Also, as indicated by arrow 43, the front cutting blade 22 first strikes the ground as the trajectory moves forward (forward for purposes of illustration). At approximately the same time, the front end 28a of the destruction blade 28 comes into contact with the ground, followed by the destruction blade 29. Eventually the cutting blade 23 engages the ground and then the entire shoe is in a generally horizontal downward position while traveling along the downtravel length of the track.

This gradual contact and continuous support under each shoe eliminates much of the instability previously encountered and allows the vehicle to run more smoothly.

More specifically, one end 28a, 29a of each of the breaking blades 28, 29 has two cutting blades 2
2 and 23, respectively. The other end 28b, 29b of each breaking blade 28, 29 extends substantially beyond the common imaginary plane 41 of each end 28b, 29b and is approximately in line with the path of the associated one of the tracks 11, 12. arranged vertically.

The use of compaction vehicles of the type described, characterized by the design of the breaking blade and shoe, makes it possible to effectively reduce the size of concrete blocks, rocks, wood products, etc. encountered in construction practice, i.e. to reduce the amount of waste. You can reduce the amount of waste by simply moving your vehicle back and forth.

It has been found that a vehicle equipped with a track of the type described achieves the desired effect more quickly than before, and the device in fact saves fuel and labor and reduces operating time.

The smooth running created by the diagonal segments prevents the equipment from rolling or tipping from one cutting blade to the next.
It not only reduces metal fatigue and equipment damage, but also improves operator comfort.

It should be noted that in many farming communities, it is illegal to burn corn stumps because farmers working in such areas are required to level the stumps on the ground. In order to make the leveling of the tracked vehicle stumps more thorough, the corn stumps placed on the ground can be crushed prior to this leveling. Furthermore,
This can be done all at once by leveling the field thoroughly with a vehicle.

Also, because the track shoe 14 is supported by conventional track links 13, the shoe 14 can be used with conventional shoes used in track type tractors. For example, the shoe 14 can be replaced by a standard shoe if desired without commensurate loss in function and efficiency.

According to one method of operation, after reducing the size of the initial waste material, the tracks 11, 12 can be moved back and forth over the waste, actually "screwing" the material into the ground in this way. .
