AI Technical Summary

Technical Problem

Existing grain warehouse cleaning equipment suffers from high equipment investment costs, low utilization rates, time-consuming and labor-intensive cleaning operations, and a high breakage rate, especially when the environment inside the grain warehouse is harsh, which affects the health of the workers.

Method used

Design a grain warehouse cleaning device that integrates a walking mechanism, a digging mechanism, a pushing mechanism, and a spiral conveying mechanism. The tracked mechanism improves traction, the digging mechanism quickly clears the grain piled up behind the grain warehouse door, the pushing mechanism reduces grain crushing, and the spiral conveying mechanism achieves full-coverage conveying, thus realizing automated cleaning.

Benefits of technology

It improves the efficiency of clearing and storage, reduces the grain breakage rate, reduces the intensity of manual labor, and achieves efficient and low-breakage clearing and storage operations, adapting to different grain storage conditions.

Abstract

This invention relates to the field of grain storage technology, specifically to a grain storage cleaning device and method. The grain storage cleaning device includes a traveling mechanism, which comprises a frame. The frame is equipped with a track mechanism and a driving system. The track mechanism has a rubber outer layer. Various cleaning devices are mounted on the frame, including a digging mechanism, a pushing mechanism, and at least two spiral conveying mechanisms. The track mechanism with a rubber outer layer reduces the breakage rate of grain during equipment movement. By integrating multiple functional cleaning mechanisms on the frame, cleaning operations can be performed for different grain storage conditions, avoiding manual cleaning and improving cleaning efficiency. Through the cooperation of multiple spiral conveying mechanisms, cleaning operations can be handled for grains in different conditions within the grain storage, achieving full coverage of grain transfer within the grain storage. This cleaning method, through the cooperation of multiple functional cleaning mechanisms, enables high-efficiency and low-breakage cleaning operations of grain within the grain storage.
