Self-vibration type corn grading device

Abstract

The invention discloses a self-vibration type corn grading device. The device comprises a base, wherein a grading box is fixedly arranged at the top of the base, an upper gathering box and a lower gathering box are arranged in the grading box, the upper gathering box and the lower gathering box are connected with the left side wall and the right side wall in the grading box respectively through supports; the bottom wall of the upper gathering box is inclined towards the lower right portion, a discharging opening is formed in the right side of the bottom wall of the upper gathering box, a baffle matched with the discharging opening is hinged to the lower right corner of the upper gathering box, a torsion spring is further connected to the hinged position between the baffle and the corresponding gathering box; magnetic attraction components matching with each other are each fixedly inlaid in the upper left corner of the baffle and the bottom wall of the upper gathering box; and an upperinclined plate and a lower inclined plate are further arranged in the grading box, the upper inclined plate and the lower inclined plate are hinged to the left side wall and the right side wall of thegrading box respectively. According to the device, the gathering boxes are arranged, when corns gather together then fall onto a net plate, gravity of the right end of the net plate suddenly increases, so that the net plate can swing up and down to screen, screening effect is good, a vibration motor and the like do not need to be additionally arranged in the screening process, screening is carried out automatically, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a self-vibrating corn grading device. Background technique [0002] Maize is an annual monoecious cross-pollinated plant with tall plants and strong stems. It is an important food crop and feed crop. It is also the crop with the highest total output in the world. Its planting area and total output are second only to rice and wheat. Corn has always been known as a longevity food, rich in protein, fat, vitamins, trace elements, cellulose, etc., and has great potential for developing high-nutrition, high-biological function foods. [0003] Corn often needs to be sieved before deep processing to ensure the quality of corn. During the sieving process of ordinary corn sieving devices, external forces are needed to make the screen swing or vibrate. For example, the vibration motor drives the screen to vibrate to ensure the screening effect. Class screening will cause was...

Problems solved by technology

[0003] Corn often needs to be sieved before deep processing to ensure the quality of corn. During the sieving process of ordinary corn sieving devices, external forces are needed to make the screen swing or vibrate. For example, the vibration motor drives the screen to vibrate to ensure the screening effect. Class screening will cause waste of energy to a certain extent, which is not conducive to reducing costs
