Wear-proof material supply device

Abstract

A wear-proof material supply device comprises a material supply pipeline (8) fixed to a machine frame, and a supply control part (6) fixedly connected with the material supply pipeline (8). The material supply pipeline (8) receives materials from a material supply bin, wherein the materials are discharged by applying supply pressure. The supply control part (6) comprises an upper cut-off plate (611) and a lower cut-off plate (621) which can extend into an internal passageway (80) of the material supply pipeline (8) in a telescopic mode to cut off the internal passageway (80). The upper cut-off plate (611) is fixedly connected with an upper drive protruding plate (613) through an upper cut-off plate connection part (61), wherein the upper drive protruding plate (613) is borne by two upper guide columns (65) in a slidable mode.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an anti-wear material supply device. Background technique [0002] In the field of agricultural machinery, it is often necessary to supply some granular materials, such as applying granular fertilizer to the field during fertilizer application, or sowing seeds into the land during sowing operations. These field operations often require mechanical equipment. [0003] Traditional above-mentioned operation often adopts the mode that gravity falls naturally to carry out. Granular material is placed into the hopper and applied dropwise to the field using a pipe extending downward from the hopper. This method is often susceptible to external interference and pipeline jamming, and requires frequent inspection and debugging of equipment during the operation, so the efficiency of the operation is low and the quality of the operation cannot be guaranteed. In addition, since the hop...
