Description

FIELD OF THE INVENTION The invention relates to municipal engineering, in particular to heavy-duty garbage trucks.

The aim of the invention is to simplify the construction of the garbage truck.

FIG. 1 shows a garbage truck, side view; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 shows a section B-B in FIG. 3; in fig. 5 is a section of YYD in FIG. 3; in fig. 6 is a section d-d in FIG. five.

The truck includes a body 1 mounted on a semi-trailer 2 articulated with a vehicle — a tack 3. In the upper front part of the body there is a loading opening 4, under which the main plate 5 is mounted and along with the additional plate 6 above it placed in the upper guides 7 by means of sliders 8 and made in the form of a bottomless bunker with the front wall 9 and the rear wall 10, which are rigidly connected to each other by means of the side walls 11. The body 1 has at the bottom Asti guides 12, which are arranged in the lower plate 13 slides 5. To the rear side of the back wall 10 rigidly attached stop 14. The upper edge of the base plate is provided with a projection 15, facing in the direction of its working stroke. Between the bottom edge 16 of the front wall 9 and the baffle plate 17 of the main plate there is a gap 18, overlapped with a visor 19 mounted on the front wall 9 by means of a hinge 20 and a spring 21 relative to it 21. The main plate is equipped with a pusher 22 mounted on the baffle plate 17 and located between the stop 14 and the rear surface of the rear wall 10. The body 1 is provided with latches 23 hinged on its side walls connected to hydraulic cylinders 24 and cooperating with the stops 25 fixed on the rear wall 10 of the additional plate 6. The main plate is equipped with a gripper in the form of levers 26 and 27 secured with free translation in the vertical direction on its bracket. The lever 26 is placed along the axis of the shaft 28 installed in the body bottom guides 29, and the lever 27 is shifted in the transverse direction. direction relative to the lever 26. The levers 26 and 27 are set offset from each other and in the longitudinal plane (FIG. 3). These displacements are determined by the angle of rotation of the rod 28 and the width of the main hooks 30 mounted on the bar 28. On both sides of the rod 28 are the hydraulic cylinders 31 of the drive, connected to it by means of a bracket 32 rigidly attached to the housings of the hydraulic cylinders 31. The rods of the latter are connected to the body 1 at help brackets 33. Rod 28 is installed

can be rotated around its axis in both directions relative to the vertical at angles and by means of a hydraulic cylinder 34. An additional grip 35 is installed on the rod 28, located symmetrically to the lever 27 relative to the rod axis. The hooks 30 are fixed on the rod evenly with a pin corresponding to the stroke of the rods of the hydraulic cylinders 31. At the rear, the body 1 is equipped with a tailgate 36 of a known design

instructions. The garbage truck is loaded through the bunker 37, which is an element of the transfer station.

Garbage truck works as follows. When a garbage truck is loaded onto the garbage dump 5 of the loading station, it is fed under the bunker 37 until the latter is combined with the loading opening 4. The garbage from the bunker 37 is freely emptied into the body 1 and is located in the bunker formed by the walls of the additional plate 6. The main plate 5 is aligned

0 with the rear wall 10 of the additional plate 6, which is fixed on the body 1 by clamps 23 that come into contact with the stops 25. The rod 28 is deployed so that the additional hook 35 of the rod 28 is opposite the lever 26, and the hook 30 is opposite the lever 27. The hydraulic cylinders 31 turn on the extension of the rods and they set in motion the rod 28, transmitting to it the compaction force through the bracket 32. Since the additional hook 35 is

0 in contact with the lever 26 connected to the main plate, the latter is also set in motion and begins to move debris from the cavity of the hopper under its front wall 9 into the free space of the body 1. The peak 19 rises in the hinge 20, compressing the spring 21, since the bottom plate is affected by it. During its entire travel, the visor 19 is in an elevated position, resting on the bumper shield 17 from above, which prevents debris from entering the gap 18 when the plate 5 moves.

 the protrusion 15 prevents debris from lifting along the working surface of the main plate 5, as a result of which debris does not get stuck in the gap 18. At the end of the stroke of the hydraulic cylinders 31, the rod 28 is located

5 with it in engagement with the main plate stops and after switching over the cavities of the hydraulic cylinders 31 to return, it returns to its original position. The main hook 30 acts on the lever 27 and moves the plate back. Right after

When the main plate returns to its original position, the hydraulic cylinders 31 switch to the working stroke and the main plate again moves toward the rear of the body 1, squeezing the next portion of garbage from the bunker to the body. Move debris inward

Body 5 is accompanied by its compaction. In this case, each newly received piece of garbage transfers the compaction force from the hydraulic cylinders 31 through the plate 5 to the volume of garbage in the body 1 and compresses it, gradually increasing the degree of compaction as the body is filled. The presence of the front wall 9 prevents the elastic expansion of debris when the main plate is retracted to its original position. The same is facilitated by the garbage entering from above into the emptying space of the bunker. The described movement cycles of the base plate continue continuously until the body 1 is fully loaded with garbage. After loading, the garbage truck moves to the places of disposal and disposal of garbage, where it unloads the body 1. For this, the hinged side of the body 36 is opened and the output cylinders 24 and the clamps 23 are engaged with the stops 25. The hydraulic cylinder 34 rotates the rod 28 on its axis at angle a an additional hook 35 to a position in which the lever 26 does not align with it, but is aligned with the main hook 30. Turn on the hydraulic cylinders 31, which move the rod 28 in the direction of the tailgate 36. The main hook 30 acts on the lever 26, which rests on it and transmits the force to the main plate, which causes it to move together with the rod 28. At the end of the stroke of the hydraulic cylinders 31, the pusher 22 reaches the rear wall of the additional plate 6 and rests against it. The cylinders 31 switch to reverse, returning the rod 28 to its original position. The main plate remains in place as the lever 26 slides over the rod 28. At the end of the return stroke of the rod 28, the main hook 30 next to its end passes under the lever 26, lifting it. Then lever

26, under the action of its own weight, returns back and, after a new switching of the hydraulic cylinders 31 to the working stroke, transmits movement from the pole 28 to the main plate. Since the pusher 22 at the same time acts on the back side of the rear wall 10 of the additional plate 6, previously unhooked from the body 1, the plate 6 moves along with the plate 5, the front wall of which with the surface of the plate 5 forms

0 pusher plate. The cyclic movements of the rod 28 continue until the movement of the plate 6 with the plate 5 over the entire length of the body 1, which ensures complete unloading of the latter. To return the plates to their original position, the hydraulic cylinder 34 rotates

 the pole 28 in the vertical plane in the direction of the side lever 27 at an angle a. In this case, the main hook 30 occupies a position corresponding to the compaction mode (Fig. 4), combined with the lever 27. Since the lever 27 is able to rise, the above-described cyclical movements of the rod 28 cause the main plate to move in the opposite direction in the same way. At the same time, upon completion of the first return stroke of the main plate, its pusher 22 abuts against the stop 14 and it begins to move together with the additional plate, returning to the front part of body 1. After completion of the reverse movement, plates 5 and 6 occupy the initial position in the body, and preparation the garbage truck to the next loading of garbage is made by fixing an additional plate in the body 1 by rotating the latches 23 by the hydraulic cylinders 24, bringing them into contact with the stops 25.
