Abstract

A compaction roller (10) includes improved cleat assemblies (18,19) which employ readily removable wear caps (29, 44). One style of cleat assembly (18) employs means inhibiting twisting of the cap unit about vertical and horizontal axes relative to the support base. A base portion (22, 38) is welded to the roller and the removable cleat assemblies (18, 19) attached by means of a coupling pin (28, 54) secured by split rings (27). The invention has application to rollers used in sanitary land fill operations and by avoiding the need to cut off welded cap units encourages cap units to be replaced when worn to thereby avoid wear damage to the roller.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention generally relates to a roll attached to a driven compaction vehicle, and to household electrical appliances such as those encountered in landfill disposal operations. This invention relates to a compaction machine such as a roll that has a combination of destructive force and tensile force suitable for crushing, crushing, and compacting materials of size. More specifically, the present invention features a cleat that is carried by rolls and is easily removable.

[Conventional technology]

Compaction rolls and compaction wheels used in landfill work, especially in landfill waste processing work, have protruding legs that crush and crush the material directly below them to reduce the size of the material through compaction. In other words, they are usually equipped with cleats. US Patent No.
No. 3,922,106 discloses a compaction roll for soil and garbage disposal that employs two different raised feet with replaceable abrasive caps as part of the cleat assembly. There is. The abradable cap is welded to the base of a cleat assembly, which is also welded to the roll.

[Problems to be solved by the present invention]

Although the above devices operate without any problems, operators of such devices are aware that the abrasive caps of the devices are still allowed to wear out past the point at which they should be replaced. In this case, the base of the roll's cleat assembly is partially worn so that the new replacement cap cannot properly fit over the base of the cleat assembly, and the roll's cleat assembly is completely worn out. must be replaced as

The main reason for not replacing abradable caps in a timely manner to avoid damage to the base that supports them is that the abradable caps are welded to the rolls and the operator cannot replace them. This can be attributed to the fact that a cutting torch must be used to separate the roll. This redundancy of onerous work exacerbates the tendency for exchanges to be detrimentally postponed.

Thus, as disclosed herein, the present invention provides a compaction roll from which abradable caps can be easily removed using common tools available in the field. . In this way, the tendency to replace abradable caps before the bases supporting them become worn to the extent that they require replacement is encouraged.

[Configuration of the present invention]

Generally, the present invention relates to a reclamation and compaction roll of the type having a cylindrical body rotatably supported by a vehicle chassis and a cleat assembly supported by the cylindrical body. The cleat assembly includes a rigid mounting pad assembly having a base attached to the cylindrical body and a cap unit attached to the base by a connecting pin, each of the cleat assemblies having further comprising a bracket integral with the base and projecting generally radially outwardly therefrom, and a coupling aperture extending across the bracket, the cap unit having an angled and upwardly converging outer sidewall; a generally hollow body including an end wall extending across between opposite ends of the side wall;

[Object of the present invention]

In general, it is an object of the present invention to provide an improved landfill and compaction roll that features an easily replaceable cleat assembly.

Another object of the present invention is to provide an improved cleat assembly that allows for easy replacement of abradable caps to avoid wear on the mounting bases that carry such caps.

Another object of the invention is to provide a type of cleat assembly that requires minimal time and effort to replace using common tools.

〔Example〕

The above and other objects of the present invention will be understood from the following description of preferred embodiments of the invention, considered in conjunction with the accompanying drawings.

A compaction roll 1 according to the invention, shown diagrammatically in FIG.
0 includes a cylindrical rigid body, or rim 11, attached to a power drive vehicle 13 (of which only a portion is shown) and connected to a centrally disposed drum. The roll assembly 10, shown diagrammatically, is manufactured by Caron Compactor.
According to the teachings of U.S. Pat.

The roll 10 is attached to a peripheral frame 14 of a vehicle 13. This frame 14 includes transverse members 16, 17 extending across the tread surface of the roll 10.
It is of the type that is equipped with.

Cleat assemblies 18, 19, which will be described in detail below, are implanted on the outer surface of the cylindrical rim 11. The primary function of cleat assembly 18 is to provide tensile force, whereas the primary function of cleat assembly 19 is to crush the material.

As shown in FIG. 3, the cleat assembly 18 includes a rigid mounting pad unit 21 having a base 22a curved along an edge 21a following the curvature of the rim 11 so as to be welded to the rigid body formed by the rim 11. include. A bracket 23 integrally formed with the base 22 projects generally radially outwardly from the base.

A coupling aperture 24 extends across the bracket 23 and is surrounded at both ends by a recess 26 having a larger diameter than the aperture.

A split ring 27, which can increase in size radially, is arranged within the recess 27 and serves to lock the connecting pin 28 in order to retain the abradable cap unit 29, but in this regard Details will be explained later. The abradable cap unit 29 is thus adapted to be easily releasably connected to the base 22. Abrasive cap unit 2
9 is an external side wall 29 that tilts upward and converges.
a and a lateral end wall 29b extending between the edges of such sloping side wall. A pair of alignment apertures 31 are provided in the bracket 23.
The side wall 29a is aligned with the connecting opening 24 of the side wall 29a.
extends through. In this way, to connect the abradable cap unit 29 to its mounting pad unit 21, the connecting pin 28 is inserted into the opening 3.
1 and the opening 24.

The easily releasable locking of the pins 28 in the openings 31, 24 serves to prevent the cap unit 29 from being uncoupled from the pad assembly 21, as will now be explained.

The diameters of the openings 31 and 24 are large enough to allow the pin 28 to be inserted easily, but the inner diameter of the split ring 27 is slightly smaller than the diameter of the connecting pin 28. Therefore, in order to dispose the connecting pin 28 completely within the opening 31, the connecting pin 28 must be press-fit through the center of each split ring 27. Therefore, as shown in FIG. 6, the connecting pin 28 is inserted through the openings 31 and 24 and through each split ring 27 to prevent the pin from becoming inadvertently or accidentally dislodged. It is arranged to do so.

If you wish to remove the cap unit 29 from the mounting pad unit 21, use a hammer to apply a screwdriver to the end face of the pin 28 and remove the cap unit until the pin 28 is uncoupled from the split ring 27. This pin can be pushed out so that it moves through 29.

A device is provided within the cap unit 29 which serves to guide the cap unit 29 in close proximity along the bracket 23.
That is, a pair of generally parallel opposing overhangs 3
2 and 33 extend radially outward along the inner surfaces of opposing inclined walls 29a of the hollow body of the cap unit 29.

The opening 31 is connected to the bracket 2 as mentioned above.
It extends through the overhangs 32 and 33 while maintaining an aligned relationship with the connection opening 24 of No. 3. Opposing surfaces 23a and 23b of a pair of lateral flanges are disposed at lateral positions relative to each end of the connecting opening 24, and guide slots for receiving the overhangs to be combined in the overhangs 32 and 33 are arranged in the above-mentioned connection. The openings 24 are formed at opposite ends thereof.

Bracket 23 includes a matching surface 23c extending between opposing surfaces 23a and 23b. When the cap unit 29 is placed over the bracket 23 as shown by the broken line in FIG.
The split ring 27 has a recess 2 on the opposite surface.
It is positioned in close relation to the alignment surface 23c of the bracket 23 so as to be sufficiently captured in the bracket 23.

Therefore, after the cap unit 29 is covered with the mounting pad unit 21 and the split rings 27 are disposed in their respective recesses, each of the overhangs 32 and 33 is Since the outer surface is in close proximity to the captured ring 27, the first ring 27 encountered when inserting the pin 28 through the first opening 31 is the first ring 27 that the pin encounters as it advances into the abradable cap unit 29. As it does so, it is expanded in the radial direction. The pins 28 then pass into the second split ring and similarly force it apart, since the outer surface of the overhang 32 associated with this second split ring holds the ring apart. This is because the pin 28 is prevented from coming out of the recess as the pin 28 moves.

Therefore, as explained above, the bracket is
It is provided with a pair of "slots" on opposite sides thereof for receiving overhangs 32 and 33. This "slot" is located on the wall surfaces 23a, 23b, and 23.
formed by c. These guide "slots" thus serve to receive in close position the projections to be assembled therein.

It will be readily apparent from the foregoing that improved cleat assemblies such as cleat assembly 18 simply cap pins 28 using conventional tools of the type found in the field. A cleat assembly has been provided which allows for easy removal of the abrasive cap by simply pushing it far enough into the unit 29 to disengage both split rings 27 from the pins. .

The time and effort required to replace worn caps in accordance with the present invention is significantly reduced so that worn caps can be replaced before the rigid mounting pad unit is damaged and must be cut and replaced. It seems likely that it will be replaced.

In this way, the extra time and expense required to cut the damaged rigid mounting pad unit 21 can be saved.

The cleat assembly 19 is primarily used for crushing, crushing, and crushing household appliance-sized materials such as those encountered in landfill operations.
It includes a rigid mounting pad unit 37 which includes a rigid metal base 38. Rigid metal base 3
8 supports an elongated and relatively thin alignment guide 39 formed integrally with this base.

The alignment guide 39 has an upwardly projecting key 42 disposed within a downwardly open pocket 43 formed within a removable abradable cap 44.
The rigid mounting pad unit 37 and the alignment guide 39 associated therewith include an upwardly extending bracket portion 41 characterized in that it has an abradable cap 44.
supports the cap from the inside in a manner that minimizes twisting and bending relative to the base 38. Therefore, both the alignment guide parts 39 and the key 42
serves to provide the three spaced support points that we are about to discuss.

The hollow interior 46 of the cap 44 has notches 47 and 4 that are inclined downwardly and away from each other to receive the tips 49 and 51 of the alignment guide 39.
8 is formed. Therefore, if the cap 44 is attached to the mounting pad unit 37 in this way,
Because the tips 49, 51 rest in the notches 47, 48, the abradable cap 44 is prevented from twisting relative to the base 38 about a straight line perpendicular to it, e.g. an axis 52. be restrained.

Above it is a key 4 engaged with a pocket 43.
3 serves to restrain the abradable cap 44 from twisting transversely to the base 38, such as about an axis 53 parallel to the base 38.

Finally, a connecting pin 54 extends through an aperture disposed across bracket portion 41, similar to that previously described with respect to bracket 23. Each end of the coupling opening 56 is, as before, surrounded by an annular recess 57.

Connecting pin 54 thus retains abradable cap 44 to the mounting pad assembly.

Finally, the underside of the base 38 is arcuate to match the circumferential surface of the rim 11 and is therefore suitable for welding to such a rim.

In this way, once the abradable cap 44 has worn out, it can be easily replaced without undue expenditure of effort or time.
