Description

TECHNICAL FIELD

[0001] The application relates to the technical field of agricultural machinery cleaning, in particular to an agricultural machinery cleaning device. BACKGROUND

[0002] The agricultural machinery refers to various machines used in crop planting and livestock production processes, and in the initial processing and treatment of agricultural and livestock products. However, in the prior art, agricultural machinery needs to drive over the soil during crop harvesting, resulting in the surface of the treated crops being contaminated with a large amount of soil. The soil clumps affect the appearance and normal use of the machinery. However, the existing mechanical cleaning method is mostly manual cleaning. Agricultural machinery is generally large in size, and a large amount of time is required to complete the cleaning, resulting in extremely low work efficiency.

[0003] The prior art document with the publication number CN216532511U provides an agricultural machinery cleaning device. The device drives the agricultural machinery onto the base. The second water pump extracts the water flow inside the water tank and sprays it on the machinery through the spray head, softening the clumped soil. The motor drives the lead screw to rotate, driving the cleaning brush on the outer surface of the machinery to slide back and forth, removing the soil. Compared with manual cleaning, the device can effectively improve work efficiency. After cleaning, the water flow enters the water collecting tank and is extracted by the first water pump to return to the water tank. The filtered water is sprayed by the spray head, achieving the purpose of saving water resources.

[0004] Although the prior art solution in the above can achieve the beneficial effects related to the prior art, it still has the following defects: the surface of the agricultural machinery equipment will adhere to a large amount of plant roots or straw during operation. The filter plate of the device cannot be cleaned mechanically, which increases the difficulty of cleaning for workers. If not cleaned in time, the filter plate will be blocked.

[0005] In view of this, we propose an agricultural machinery cleaning device. CONTENT OF THE INVENTION
