Threshing and separating device with concave clearance self-exciting adjustment function

Abstract

The invention discloses a threshing and separating device with a concave clearance self-exciting adjustment function. The device comprises a feeding protection cover, a top cover, a drainage guide plate, a separating concave plate, a separating concave plate self-exciting adjustment mechanism, a threshing concave plate, a threshing concave plate self-exciting adjustment mechanism and a threshing roller, wherein the threshing concave plate and the separating concave plate are arranged side by side in the lower portion of the threshing roller, and the threshing concave plate is arranged closer to the feeding side of the threshing roller; the top cover is arranged at the upper portion of the threshing roller, the feeding protection cover is arranged at the feeding side of the threshing roller, and the drainage guide plate is arranged at the output side of the threshing roller; the threshing concave plate self-exciting adjustment mechanism is arranged between the threshing concave plate and the top cover, and the separating concave plate self-exciting adjustment mechanism is arranged between the separating concave plate and the top cover. The threshing and separating device with the concave clearance self-exciting adjustment function has the advantages that the structure is compact and reasonable, the work is stable and reliable, the detachment is convenient, threshing is low in injuries, and blocking is prevented.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a threshing and separating device for self-excited adjustment of concave plate gaps. Background technique [0002] In recent years, with the improvement of my country's corn mechanized harvesting level, especially the research and development of corn grain harvesting technology, direct harvesting of corn grains will become the development direction of corn harvesting in my country. Harvesting corn grains can effectively reduce food loss, reduce labor intensity, improve production efficiency, and achieve cost savings and efficiency gains. At the same time, corn can be harvested without landing, and it can be directly stored in the warehouse after being dried by drying equipment, improving food grades and reducing food pollution. [0003] However, at present, the grain moisture content of corn in my country is relatively high when harvested, which is gene...

AI Technical Summary

Problems solved by technology

However, during the threshing process, the corn ears are rubbed and hit by the threshing element and the concave plate with a relatively large force, which will also cause the corn kernels with high moisture content to be more likely to break when threshing is achieved.
