Flexible disturbance spike tooth mechanism of high-moisture-content corn threshing cylinder

Abstract

The invention relates to a flexible disturbance spike tooth mechanism of a high-moisture-content corn threshing cylinder. The mechanism comprises a cylinder body, spike tooth supports and spike teeth,the cylinder body comprises a plurality of annular cylinder shells arranged along the axial direction of the cylinder shaft and a plurality of plurality of supporting devices arranged between the cylinder shaft and the cylinder shell, the spike tooth supports are uniformly arranged along the outer circle of the cylinder shell, the spike tooth support is internally provided with a space for accommodating the disturbance mechanism, the upper end of the spike tooth is a coarse end thread, the downward sequence is a coarse end cylinder, a fine end cylinder and a fine end thread, the spike teeth are arranged on the spike tooth supports and are matched with the disturbance mechanism, so as to realize the telescopic and lateral swinging motion of the spike teeth in the radial direction. The flexible disturbance spike tooth mechanism of a high-moisture-content corn threshing cylinder has the advantages of flexible threshing, low kernel loss rate, easy maintenance and replacement.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a flexible disturbance nail-tooth mechanism of a corn threshing cylinder with high moisture content. Background technique [0002] The high threshing loss rate has always restricted the promotion and development of corn threshers. Winter wheat and summer corn are rotated twice a year in the Huanghuaihai region, and the corn growth cycle is short. When the thresher is used for threshing, problems such as severe grain breakage and high loss rate will inevitably occur. The teeth of the existing traditional threshing drum are fixed on the tooth bar by welding, and the rigid teeth directly hit the ear of corn to cause the grains to be broken. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, and propose a flexible perturbation spike mechanism for threshing drums for corn with high moisture content, whi...

[0002] The high threshing loss rate has always restricted the promotion and development of corn threshers. Winter wheat and summer corn are rotated twice a year in the Huanghuaihai region, and the corn growth cycle is short. When the thresher is used for threshing, there will inevitably be problems such as severe grain breakage and high loss rate.

The teeth of the existing traditional threshing drum are fixed on the tooth bar by welding. The rigid teeth directly hit the ear of corn and cause the grains to break.
