Description

Technical Field

[0001] The utility model relates to the technical field of bulldozer push plate replacement, in particular to a push plate for a bulldozer. Background Art

[0002] A bulldozer is an engineering vehicle with a large metal push bucket in front of it. When in use, the push bucket is lowered to shovel and push mud, sand and stones forward. The position and angle of the push bucket can be adjusted. It can complete the work of digging, transporting and unloading soil alone. The bulldozer has the characteristics of flexible operation, easy rotation, small working surface and fast driving speed.

[0003] After searching, it was found that the Chinese patent publication number CN207878526U disclosed "A bulldozer push hopper", which includes a fixed hopper for holding materials and a shovel plate arranged on the lower side of the hopper, the hopper includes an arc-shaped push plate and baffles arranged at both ends of the push plate, and multiple groups of stirring paddles for crushing the internal materials are arranged in parallel with the push plate in the hopper, and a driving device arranged on the outside of the hopper is rotatably connected to the stirring paddle; by adopting the above technical solution, the materials are scooped up and transported by the hopper and the shovel plate, and the stirring paddle arranged in the material hopper can crush the materials loaded in the material hopper. The material in the hopper can be stirred. When the material is transported by the material container in the cold winter, the lumps in the material can be stirred to keep it in a uniform state and prevent it from condensing easily. The protective plate can protect the rotating shaft, so that the rotating shaft is not easily caught by large stones. At the same time, the long groove can allow the stirring blade to pass through and stir in the hopper. By rotating the material blocking door at the sand outlet, the material blocking door abuts against the sand outlet during the material loading process, so that the material cannot enter or exit from the sand outlet. When pouring the material, the material behind the protective plate is automatically discharged from the sand outlet.

[0004] In actual use, the push plate of a current bulldozer is connected to the bulldozer hydraulic device by a hinge device, and generally, the components of the hinge device need to be disassembled during disassembly, which affects the replacement efficiency of the push plate.
