Description

Threshing concave sealing device and harvester with adjustable Technical Field The utility model relates to the technical field of threshing equipment of a harvester, in particular to an adjustable threshing concave sealing device and the harvester. Background In the existing grain harvesting machinery, after materials enter a threshing machine body in the threshing operation process, threshing separation is carried out under the rotation action of a roller. However, crop stalks tend to accumulate or twist between the sides of the drum and the recess plates under the tangential movement of the drum, which is more pronounced when the feed is increased. The accumulation and winding of the stalks can cause the blockage of the gap of the concave plate, cause local high temperature, cause the damage of working parts and influence the threshing efficiency and the separation effect. Disclosure of utility model The utility model aims to solve the technical problem of providing an adjustable threshing concave sealing device and a harvester aiming at the defects of the prior art. The technical scheme includes that the threshing concave sealing device comprises a sealing plate, a pair of locking mechanisms, threshing concave fixing plates, a pair of second reinforcing plates, a pair of first fixing plates matched with the locking mechanisms, a middle partition plate, a partition plate and a pair of second fixing plates matched with the locking mechanisms, wherein the top of the sealing plate is hinged with the threshing concave fixing plates, the locking mechanisms are arranged on two sides of the bottom of the sealing plate, the first fixing plates are respectively arranged on the second reinforcing plates, and the second fixing plates are respectively arranged on the middle partition plate and the partition plate. The technical scheme has the beneficial effects that the angle of the sealing plate can be flexibly adjusted according to different working conditions, falling grains can be effectively prevented, and the phenomenon of unilateral accumulation caused by rotation of the roller is prevented. The threshing efficiency is improved, and the service life of the working part is prolonged. Further, a plurality of first reinforcing plates are mounted on the outer surface of the sealing plate, and a pair of locking mechanisms are respectively mounted on the first reinforcing plates located on both sides of the sealing plate. The technical scheme has the advantages that the first reinforcing plate ensures the structural strength of the sealing plate and prevents the sealing plate from deforming in the working process. And a locking mechanism is welded on the first reinforcing plates at two sides of the sealing plate respectively and used for fixing the welding installation position of the sealing plate, so that the gap between the sealing plate and the threshing concave plate is ensured to meet the working condition requirement.
