Embodiment 1

[0029] Such as Figure 1 to Figure 5 As shown, the threaded rod mechanism 100 of this embodiment includes a base 110, a first rotating shaft 120, a threaded rod block 130, an upper adjustment column 140, a sleeve 150, a spring 160, a bolt 170, a nut 180 and a lower adjustment column 190;

[0030] The base 110 is U-shaped with a horizontal bottom, including a bottom plate 111 and side plates 112 erected on both sides of the bottom plate 111. The two ends of the first rotating shaft 120 are respectively connected to the two side plates 112, and the threaded rod block 130 is connected to the first rotating shaft 120. The threaded rod block 130 can rotate around the first rotating shaft 120, and the surface of the threaded rod block 130 is provided with a chute;

[0031] The sleeve 150 is vertically installed on the bottom plate 111, and the surface of the sleeve 150 is provided with a pair of axial long grooves 151, and a scale mark 152 is arranged beside the long grooves 151, an...

Abstract

The invention discloses a rasp bar mechanism. The rasp bar mechanism comprises a base, a first rotating shaft, a rasp bar block, an upper adjusting column, a sleeve and an elastic body. The surface ofthe rasp bar block is provided with inclined grooves. The rasp bar block is installed on the base through the first rotating shaft. The rasp bar block can rotate around the first rotating shaft. Thesleeve is installed on the base. The elastic body is located in the sleeve. The upper adjusting column is connected with the rasp bar block. The upper adjusting column is inserted into the sleeve andlocated above the elastic body. According to the rasp bar mechanism, the rasp bar block is used to configure the first rotating shaft and the elastic body, so that the gap between the rasp bar block and a sieve cylinder can adaptively change with the change of the size of bean pods when the rasp bar mechanism is used. The rasp bar block is always in contact with the bean pods and applies basicallythe same pressure on the bean pods, thereby ensuring that both large and small bean pods can be threshed normally without damaging seeds.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a threading rod mechanism and an edible bean threshing cylinder using the threading rod mechanism. Background technique [0002] The Chinese patent application "A Combine Harvester for Edible Beans" with the application number 202010018644.9 discloses an edible bean threshing mechanism (see the attached description of the application for details). Figure 4 ), mainly including a screen drum, a rotating shaft and a grained rod block, the rotating shaft drives the grained rod block to rotate in the screen drum, and the grained rod block and the inner wall of the screen drum rub the pods to realize threshing of edible beans. [0003] The defect of the edible bean threshing mechanism in the prior art is that the gap between the corrugated bar block and the sieve drum is fixed, which makes the threshing effect of pods of different sizes very unstable in the gap of a fixed size. Sm...
