Description

This invention relates to garbage trucks used to collect, compact and transport garbage.

A garbage truck is known, including a body mounted on a vehicle, in the front part of which a loading device with a gripper for containers 13 is mounted on top.

The disadvantage of this garbage truck is that it ensures the seizure of containers located directly in front of the garbage truck cabin, which narrows the technological capabilities of the latter, preventing it from seizing containers located on the lateral sides of the body.

The closest to the technical essence of the invention is a garbage truck, including a body mounted on a vehicle on which a curvilinear guide is attached to the front part of the body with a frame placed on it, equipped with a retractable jib for containers, executed as a rotary in the vertical the plane of the fork, one of the teeth of which is mounted for movement relative to the other 2.

The said garbage truck does not allow the containers to be seized on both sides of the body without additional maneuvering of the vehicle, which limits the technological capabilities of the garbage truck and its scope.

The purpose of the invention is to expand the technological capabilities of the garbage truck by ensuring that the container 10 is grasped on both sides of the body without additional maneuvering of the vehicle.

The goal is achieved by the fact that the curvilinear guide has

15 in terms of the shape of the ring.

 In order to increase the operational capacity of the garbage truck, the swiveling boom is equipped with a vertical bracket rigidly attached to its end, and a 20 nd arm with a drive, one end of which is pivotally attached to the bracket and the other to the pick fork for containers.

The drive is made from a hydrocylinder mounted on a vertical bracket and lever Iexpansion consisting of two pivotally connected ends of the levers, the free end of the first of which

30 is pivotally attached to the cylinder, and the free end of the second lever is vertically attached. , to the shaft bracket and to the hinge joint with the cylinder rod. FIG. 1 schematically shows a garbage truck, side view; in fig. 2 is the same front view at different gripping positions for containers; in FIG. 3 - the same plan view; in fig. 4 - loading device of the garbage truck, side view; - on fig., 5 - the same plan view. The truck includes a body 1 with hinges attached to it by a tailgate 2 and a loading hatch 3. A plate 4 is installed inside the body. The body is mounted on the vehicle 5, on which a guide b is attached to the front part of the body, . On guide 6, on rollers 7, there is a movable frame 8 with a drive 9, on which a sliding boom 11 with rollers 12 is mounted on the guides 10, equipped with a drive 13. A vertical bracket 14 is rigidly attached to the end of the lifting arm, to the upper end of which axis 15 is hingedly attached to a ha 16. To the opposite end of the last, a gripper 17 for containers 18 is attached hingely. The gripper 17 is made in the form of a fork that is rotatable in a vertical plane from the hydraulic cylinder 19, one of the teeth of which is relocatably mounted about another by means of a hydraulic cylinder 20. Tha 16 is equipped with a drive made of hydraulic cylinder 21 mounted on a vertical bracket 14 and a lever mechanism consisting of a hinge but interconnected by the ends of levers 22 and 23. The free end of lever 22 is pivotally attached to the tractor 16, and the free end of the lever 23 is connected to the vertical bracket and is hingedly connected to the hydraulic cylinder rod 21. Between the front wall of the body and the vehicle cabin there is an opening 24 of the passage of the vertical bracket 14 and 16 body on the other. Frequently, the bottom 25 of the body, adjacent to the rear side 2, has a slope to the latter, the tailgate being made in the form of a tank, the lower edge of the bottom of which is located at the level of the lower side of the inclined part of the body bottom. Garbage truck works as follows. When the garbage truck moves along the route, the grip 17 is in the transport position (position 1, Fig. 1 above the loading hatch 3. If it is necessary to reload the garbage into the garbage truck from the container located on the right or left side of the body, by means of the drive 9 move the frame 8 to the desired the side along the annular guide 6; the boom 11 is used to drive the boom 11 and the hydraulic cylinder 21, which acts on the levers 22 and 23, lowers the grip 16 and the grip 17, the teeth of which secure the wall of the container 18 ( Position P, Fig. 2). With the subsequent extension of the rod of the hydraulic cylinder 21 and the simultaneous movement of the boom 11, the container 18 rises, maintaining a vertical position, eliminating spilling debris, approaching the garbage truck body (position MJ, Fig.2). the body (position 1, fig. 2) is carried out by further advancing the rod of the hydraulic cylinder 21, as well as by means of the hydraulic cylinder 19. The empty container is returned to its original position in the reverse order. As the body is filled with debris, plate 4 periodically pushes it in the direction of the tailgate 2, In addition, the plate 4 unloads debris through the open tailgate. By performing this garbage disposal, containers are seized on both sides of the body without additional maneuvering of the vehicle, which significantly expands its technological capabilities. This design of the garbage truck by reducing the forces arising in the elements of the boot device also increases the operational reliability. Claim 1. Garbage truck comprising a body mounted on a vehicle on which a curvilinear guide with a frame placed on it and fitted with a retractable jib for containers, made in the form of a fork pivotally in a vertical plane, is mounted on it which is movable relative to the other, characterized in that, with the aim of expanding the technological capabilities of the garbage truck by ensuring the capture of containers on both sides of the truck without additional maneuvering of the vehicle, the curved guide has a ring shape in plan. 2. The POP.1 garbage truck, I distinguish it with the fact that, in order to increase operational reliability, the swivel boom is equipped with a vertical bracket rigidly attached to its end, and a pull with an actuator, one end of which is pivotally attached to the bracket, and the other is for the container fork. 3. The garbage truck in accordance with claim 2, is also distinguished by the fact that the drives are made of a hydraulic cylinder mounted on a vertical bracket and a lever mechanism consisting of two pivotally interconnected ends of the levers, the free end of the first of which is pivotally attached The free end of the second lever is connected to the vertical bracket and is pivotally connected to the hydraulic cylinder rod.
