Problems solved by technology

[0006] In order to overcome the problems that the screening device and winnowing device of the existing corn thresher usually need to be driven by a separate motor, and its transmission structure is relatively complicated and prone to failure, a new method is proposed to directly use the main motor shaft of the corn thresher to simultaneously drive the screening device A kind of corn thresher with screening and winnowing device, and simple transmission structure, its technical scheme is as follows:

Abstract

The invention relates to the field of farm machineries, and in particular relates to a corn thresher with a screening and winnowing device. The corn thresher comprises a feed hopper, a threshing device, a discharge opening and a motor, wherein a threshing rotary shaft is arranged in the threshing device, one end of the threshing rotary shaft is connected with the motor, a winnowing device is arranged at the lower part of the threshing device, the winnowing device comprises a winnowing box, a feeding opening and a blade, the blade is directly connected with one end of a motor shaft, and the other end of the motor shaft is connected with the threshing rotary shaft of the threshing device through a belt and a belt pulley; and a screening device is arranged at the other end of the threshing device and comprises a screening box, a screen and a vibration rotary shaft connected with the screen, and the other end of the threshing rotary shaft is directly and eccentrically connected with the other end of the vibration rotary shaft. The corn thresher disclosed by the invention has the advantages that one motor simultaneously and synchronously drives the threshing rotary shaft to rotate, the screen to vibrate and the blade of the winnowing device to rotate, and the threshing device also threshes corns; and the screen vibrates to screen niblets and corncobs.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a corn thresher with screening and winnowing devices. Background technique [0002] After the traditional corn thresher threshes the corn through the threshing device, the corncob and corn kernels are separated from each other, and then the separated corn kernels are screened through a screen to screen out some of the smaller core residues, but the existing There are mainly two types of screening devices. The first one is to directly install a screen at the outlet of the corn kernels. The corn kernels and some blocky core residues fall directly on the screen, so that the corn kernels pass through the screen. For example, the patent number is 200920065719.8, the application date is August 25, 2009, and the invention patent titled "a kind of corn thresher" has a technical scheme including a frame and a corn cob inlet at the upper end of the frame. , The threshing cylinder is ...
