Wind energy-based efficient wheat screening device capable of automatic feeding

Abstract

The invention relates to the technical field of wind energy utilization and discloses a wind energy-based efficient wheat screening device capable of automatic feeding. The wind energy-based efficientwheat screening device capable of automatic feeding comprises a box body. Material-containing plates are fixedly connected to the inner top wall of the box body. A fixed plate is fixedly connected inside the box body. A movable plate is movably connected to the top of the fixed plate. A power box is fixedly connected to the left side of the box body. A spiral spring is arranged above the power box. A fourth rotary shaft is rotatably connected to the left side of the spiral spring. A big fan is fixedly connected to the left side of the fourth rotary shaft. A small fan is fixedly connected to the inner left wall of the box body. According to the wind energy-based efficient wheat screening device capable of automatic feeding, the big fan is driven to rotate through wind power; force accumulation is conducted on the spiral spring through the fourth rotary shaft by the big fan, and then stable power is generated when the spiral spring loosens gradually by utilizing the elastic force of thespiral spring; the movable plate is driven to slide in a sliding groove in the top of the fixed plate through a transmission mechanism, and thus wheat is conveyed onto a screen mesh intermittently; and the wind power source is utilized, and in addition, the screening cost is also lowered.

Description

technical field [0001] The invention relates to the technical field of wind energy utilization, in particular to a high-efficiency wheat screening device that can automatically load materials based on wind energy. Background technique [0002] Due to the uneven heating of various parts of the earth's surface caused by solar radiation, the pressure distribution in the atmosphere is unbalanced. Under the action of the horizontal pressure gradient, the air moves horizontally to form wind. Wind energy is a renewable clean energy with large reserves and wide distribution. , so the utilization value of wind energy is very large. In some windy areas, wind energy can be used for wheat screening. [0003] The existing wheat sieving device usually pours wheat into the device for sieving. It is difficult to grasp the amount of wheat poured in. If too much wheat is poured in, it is easy to cause the screen to be blocked, and if it is too little, the screening efficiency will be too low....

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a high-efficiency wheat screening device that can automatically load materials based on wind energy, which has the advantages of effectively utilizing wind resources to reduce screening costs and prevent screen blockage, and solves the problem of general wheat screening devices. When pouring wheat into the device for screening, it is difficult to grasp the amount of wheat poured in, which reduces the practicability of the screening device, and generally uses an external power device, which cannot be effectively used in some areas with abundant wind energy resources Wind energy, causing waste of energy and raising the cost of screening
