Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0027] The state of the art related to the feeder: "Study on the relationship between the feeding form of corn ears and the breakage rate of corn" (Henan University of Science and Technology, School of Vehicle and Power Engineering, Li Xinping) studied the impact of different feeding directions on the breakage rate . However, the feeding direction only includes the two entry directions of the corn cob, and does not include the posture of the corn cob itself. In the corn thresher of 201210231110.X, a corn feeding assembly is installed above the threshing drum, and a stopper for limiting the position of the ear of corn during the threshing process is also arranged between the corn feeding assembly and the threshing drum. The limit piece can control the state of the corn during ...

Abstract

The invention discloses a flexible threshing roller, which is composed of a core shaft, a sleeve shaft and an elastic shaft. The core shaft is fixed in the sleeve shaft, and the sleeve shaft is fixed in the elastic shaft. The flexible threshing roller adopts a multi-layer structure, and the mandrel in the inner layer can maintain the overall strength of the threshing roller and avoid bending during work. The sleeve shaft in the middle is a prismatic structure, and the protruding part extends into the elastic shaft. The threshing teeth on the outside of the elastic shaft can periodically remove corn kernels. Since the inside of the threshing tooth is a rigid protrusion, the overall strength of the threshing roller is guaranteed. When the threshing roller rotates, the protrusion provides a tangential impact force to ensure that the corn kernels are cut off. The invention also discloses a corn thresher.

Description

technical field [0001] The invention relates to a flexible threshing roller, and also relates to a corn thresher with the flexible threshing roller. Background technique [0002] "Design of Vertical Axial Flow Threshing Device and Control System of Corn Combine Harvester" (School of Mechanical Engineering, Jinan University, Zhang Kun, etc.) designed a longitudinal axial flow threshing device, which has a single threshing roller with short grain on the outside of the threshing roller. rod and threshing claws. The layout of the threshing roller is simple, the threshing efficiency is low, and it cannot adapt to corn cobs of different sizes. [0003] "Design and Experiment of Helical Teeth Corn Threshing Machine with Variable Diameter and Variable Pitch" (School of Mechanical and Electronic Engineering, Northwest Agriculture and Forestry University, Zhao Wuyun, etc.) aims to correct threshing according to the difficulty of threshing and the breakage rate of corn kernels on the ...
