Crop seed processing, cleaning and screening equipment

Abstract

The invention relates to the related technical field of screening equipment, and discloses crop seed processing, cleaning and screening equipment. The crop seed processing, cleaning and screening equipment comprises a machine frame, a feeding box is fixedly installed on one side of the top end of the machine frame, a discharging plate is fixedly installed at the bottom of the machine frame, and adriving motor is fixedly installed in the middle of one side of the surface of the machine frame; and a driving shaft located in an inner cavity of the machine frame is fixedly installed on an outputshaft of the driving motor, and main integration shafts located on the horizontal side of the driving shaft are movably installed on the front side and the rear side of the inner wall of the machine frame. A screen is made of a flexible material, so that in the process that the driving shaft drives the screen to rotate, the upper screen body and the lower screen body of the screen are attached together through the auxiliary integration shaft and the main integration shaft, and when crop seeds are clamped to the upper screen body, the seeds move relative to screen holes in the lower screen body, further, the crop seeds clamped in the screen holes in the screen are pushed out through the relative movement of the seeds and the screen holes, and finally, the purpose of self-unblocking is achieved.

Description

technical field [0001] The invention relates to the related technical field of screening equipment, in particular to a processing, cleaning and screening equipment for crop seeds. Background technique [0002] In order to make the crops grow stably after planting, it is necessary to screen the seeds of the crops before planting, remove the unfulfilled and shriveled seeds, and at the same time include the cleaning of fine sand, soil and other powder impurities in the crop seeds, Thereby increasing the survival rate of seeds after planting. [0003] The working principle of the existing crop seed screening is as follows: the vibrating screen is shaken by a vibrating motor, and then the crops placed on the vibrating screen are screened. [0004] However, in the actual use process, because the aperture of the vibrating screen is fixed, some crop seeds that are not much different from the aperture of the vibrating screen are blocked on the vibrating screen, so that the screen ca...

Problems solved by technology

[0004] However, in the actual use process, because the aperture of the vibrating screen is fixed, some crop seeds that are not much different from the aperture of the vibrating screen are blocked on the vibrating screen, so that the screen cannot be screened. Greatly reduces the screening efficiency
