Description

Technical Field

[0001] The present application relates to the field of automobile technology, and more specifically, to a material unloading device for a box-type garbage truck. Background Art

[0002] People's lives and production produce a lot of garbage. The way of garbage disposal has evolved from landfill in the early days to incineration. The garbage compression station compresses the collected garbage and packs it into blocks. The box-type garbage truck transports the garbage blocks to the garbage incineration plant. The box-type garbage trucks currently on the market use the box body to flip for unloading, such as the functional self-loading and unloading garbage truck with Chinese patent number CN110027825A.

[0003] This flip structure adds a secondary beam to the upper part to carry the load, which makes the center of mass of the whole vehicle high, indirectly affecting the safety of the vehicle. In addition, when the box body flips as a whole and the flip angle is not enough to drive the garbage block to move, the rear axle of the whole vehicle will be loaded with a large load instantly, which may cause the driving area of ​​the vehicle to tilt upward. In view of the above problems, we propose a unloading device for a box-type garbage truck. Utility Model Content

[0024] refer to Figure 1-4 , a technical solution proposed.

[0025] like Figure 1 and Figure 2As shown in , the vehicle chassis 1 is a pure electric chassis; the bottom surface of the compartment 2 is a plane, and a compartment connector 22 is fixedly connected to the bottom end of the compartment. The compartment connector 22 is divided into an upper and a lower part, and the upper and lower parts form a group, connecting the compartment 2 and the vehicle chassis 1 together;

[0026] like Figure 2 As shown, the inner wall of the box body 2 is fixedly provided with a box body bottom frame longitudinal beam 21, and the middle part of the box body bottom frame longitudinal beam 21 is connected with an oil cylinder 3, and the oil cylinder 3 is a multi-stage cylinder, and the specific stroke that the multi-stage cylinder can extend meets the unloading stroke required by the push plate 4;

[0027] like Figure 2 and Figure 3 As shown, the other end of the oil cylinder 3 is connected to one end of the push plate 4, and the push plate 4 is fixedly connected to the push plate slider 41. The movement of the push plate 4 can drive the push plate slider 41 to move. The push plate slider 41 cooperates with the carriage slide rail 23. The carriage slide rail 23 is symmetrically arranged on the inner side of the carriage 2. The push plate slider 41 can slide along the carriage slide rail 23, and the carriage slide rail 23 is the movement path of the push plate 4.

[0028] like Figure 1 and Figure 4 As shown, a plurality of positioning members 5 are symmetrically arranged at the top of the compartment 2, and the positioning members 5 and the highest position of the push plate 4 are in the same straight line. When the push plate 4 is located at the inner wall of the compartment 2, it is in a garbage loading state. When the push plate 4 moves to the other side of the compartment 2, it can push the garbage in the compartment 2 out of the compartment 2 and out of the rear door of the compartment to complete the unloading.

[0029] When unloading operation is carried out, the vehicle chassis 1 drives the hydraulic oil, and the hydraulic oil drives the cylinder 3 to extend the stroke. The cylinder 3 pushes the push plate 4 to move. The movement of the push plate 4 drives the push plate slider 41 to move. The push plate slider 41 cooperates with the compartment slide rail 23. The push plate slider 41 slides along the compartment slide rail 23, limiting the movement trajectory of the push plate 4, pushing the garbage out of the rear door of the compartment 2, and completing the unloading action; after unloading is completed, the cylinder 3 retracts its stroke, driving the push plate 4 to return to the starting position, and finally a complete set of unloading and resetting actions.

[0030] Although examples of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
