Grain gravity grading stone removing machine

Abstract

The invention discloses a grain gravity grading stone removing machine. According to the machine, the connecting position of an adjusting rod and a stone removing device is adjustable. The grain gravity grading stone removing machine comprises a feeding device, a stone removing device located on the lower portion of the feeding device, a bearing mechanism used for supporting the stone removing device and an air suction device arranged on the side of the stone removing device. The bearing device comprises a bearing spring arranged on one side of the lower portion of the stone removing device and the adjusting rod located on the other side of the lower portion of the stone removing device. The stone removing machine is characterized by further comprising a lower transverse rod and an upper transverse rod. The upper transverse rod is fixed to the lower portion of the stone removing device, a plurality of annular grooves are formed in the upper transverse rod and the lower transverse rod in the axial direction, the annular grooves in the upper transverse rod and the lower transverse rod are opposite in pair, an upper mounting hole and a lower mounting hole are formed in the two ends of the adjusting rod, the upper transverse rod penetrates the upper mounting hole, and the lower transverse rod penetrates the lower mounting hole.

Description

Technical field [0001] The invention relates to grain sorting equipment, in particular to a grain gravitational grading stone removing machine. Background technique [0002] Grain stone remover is a kind of equipment widely used in branch factories in grain processing. It is mainly used to remove large impurities such as stones contained in grains. Gravity grading stone remover is a kind of grain stone remover. Gravity grading stone remover mainly includes feeding device, stone removing device, elastic support mechanism, suction device and vibration motor. Gravity grading stone remover can divide materials into heavy materials, light materials, when and light impurities. The elastic support mechanism of the traditional gravity classifier stone remover usually uses two support springs installed on both sides of the lower part of the stone remover. The problem with this type of support is that the angle of the stone remover cannot be adjusted and cannot be adjusted according to th...

AI Technical Summary

Problems solved by technology

The elastic support mechanism of the traditional gravity grading destoner usually adopts two support springs installed on both sides of the lower part of the destoner device. The problem with this support method is that the angle of the destoner device cannot be adjusted, and the The inclination of the stone removal device can be changed according to the different grains. In the existing gravity grading stone removal machine, a telescopic adjustment rod is set on one side of the stone removal device to adjust the angle of the stone removal device, but this structure still exists. The disadvantage is: the horizontal position of the adjustment rod is fixed, and the connection position with the stone removal device is also unchanged. When the vibrating screen in the stone removal device is displaced due to long-term use, the adjustment rod cannot change the connection position as required , so as to ensure more stability and reliability when adjusting the angle of the stone removal device
