Abstract
The utility model discloses a concave grid of a micro-combine harvester, which comprises a framework and a screen, and is characterized in that circumferential steel wires pass through axial perforated flat steels to form the meshes of the screen. The utility model has high threshing rate of grain.
Description
Technical field
The utility model relates to a kind of concave grate of miniature combine harvester, is specifically related to the high concave grate of a kind of threshing performance.
Background technology
Sieve is very important in the sheller unit of a miniature combine harvester workpiece, and its effect is to cooperate threshing cylinder, and grain ear is carried out threshing.General sieve commonly used especially for the concave grate of miniature combine harvester, the not high shortcoming of threshing performance occurs easily.
The utility model content
At the prior art above shortcomings, the technical problems to be solved in the utility model provides the higher sieve of a kind of threshing performance.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of concave grate of miniature combine harvester, comprise skeleton and screen cloth, and it is characterized in that: the mesh of screen cloth penetrates axial band steel with holes by circumferential steel wire and forms.
This sieve is through evidence, cereal threshing performance height.
In order to make the convenient processing of the utility model, gain in strength and rigidity, do the improvement of following aspect:
Further, the hole of wearing steel wire on the described band steel is uniform along its long axis direction segmentation, and is intersegmental for strengthening the frame position of concave grate rigidity.
Further again, it is band steel or angle steel that described skeleton and threshing casing are installed the joint portion, and mesh is intersegmental to be round steel or band steel.
Further, being welding between the skeleton of described steel wire and installation joint portion, is to weld between intersegmental skeleton of mesh and axial band steel with holes.The hole of wearing steel wire on the described band steel is positioned on the band steel axis of symmetry.
