Embodiment 1

[0024] like figure 2 In, in this embodiment, the distance between the connection axes 101 in any two groups of adjacent flexible decarning unit group 1 is the same as the difference between the outer diameter of the decarning unit 102 and the inner diameter. The distance between the adjacent molty units on the same continuous connection 101, between the decarrency unit in any one -granular unit and the previous set of flexible decarning unit group 1 and the next set of flexible decarning unit group 1 Both formation of desktop holes 3 for the separation of valves.

Embodiment 2

[0026] like Figure 4 In, in this embodiment, the height of the decarning unit is equal to the distance between the adjacent decarrency units located on the same connection 101, and any two groups of adjacent flexible decarning unit group 1 The connection axis 101 in the connection axis 101 The distance between the distance between the outer and the inner diameter of the decarning unit is greater; between the two decarrency units on the same connected axis 101, between the decarring unit and the previous set of flexible decarrencies group 1, and Between the desktop units in the next set of flexible decarning unit group 1, the desktop pores 3 for the separation of the valley are formed.

[0027] When the present invention is matched with the decarcular roller, at the moment when the two are in contact, because the material of the decarrencling unit is hollow -resistant rubber, the rigidity impact is a flexible impact, which can greatly reduce the impact when contacting; at the same ...

Abstract

The invention provides a flexible concave plate screen with a rotatable threshing unit, comprising several groups of flexible threshing unit groups, each group of flexible threshing unit groups including a connecting shaft and a threshing unit spaced and rotatably arranged on the connecting shaft, the connecting shaft It is fixedly arranged on several side arc plates arranged in parallel, and the threshing units on any two adjacent flexible threshing unit groups are staggered. The material of the threshing unit is hollow wear-resistant rubber, and the rigid impact is changed to a flexible impact, which can greatly reduce the impact force during contact; at the same time, the hollow wear-resistant rubber threshing unit can rotate around the connecting shaft during the threshing process. Rolling threshing can be achieved in the middle of the process, and the shearing force generated by the rolling pressure can separate the grain of the millet from the grain and increase the threshing rate.

Description

Technical field [0001] The present invention belongs to the field of agricultural machinery and equipment, and it involves a flexible concave plate with a rotatable despair unit. Background technique [0002] The method of harvesting of Guzi tradition is mainly harvested by artificial harvesting, and then valley is macated with stone. This will not only have high labor intensity and low production efficiency, but not ease. Today, the level of agricultural mechanization is continuously improved. The method is not to meet the requirements of society, so the production of Gutzi in my country will be far from enough, and at the same time, it also greatly limits the development of valley and its related industries in our country. [0003] At present, Guzi de -granules are mainly used in the form of full feed and are improved on the basis of the previously developed wheat rice. Cooperate, and the existing grid format sieves are mostly fixed structures. In the process of colliding with ...
