Description

Technical Field

[0001] The utility model relates to the technical field of stone removal machines, in particular to a material backflow prevention device for a wheat stone removal machine. Background Art

[0002] The destoner is a kind of impurity removal equipment that utilizes the difference in density and suspension speed between granular materials (paddy, brown rice, rice, wheat, etc.) and minerals (mainly quartz, etc.), and uses mechanical wind power and a screen surface that reciprocates in a certain trajectory to separate minerals from granular materials. It is an essential key equipment in the rice and wheat processing technology.

[0003] In the prior art, the utility model of Chinese patent application No. 202020871800.1 discloses a wheat stone removal machine anti-reversal device, including: a stone removal machine body, a mounting base and a regulator, a feed port and an air suction port are provided above the stone removal machine body, the air suction port is provided with an air volume adjustment handle, a discharge port and a stone discharge port are provided at the lower part of the stone removal machine body, the discharge port is provided with a discharge port camera, the stone discharge port is provided with a stone discharge port camera, a support rod is provided on one side of the mounting base, and a lifting rod is provided on one side, the support rod is rotatably connected to the front end face of the stone removal machine body, the lifting rod includes a first lifting rod and a second lifting rod, the first lifting rod and the second lifting rod form a triangular shape, the top is rotatably connected to the rear end face of the stone removal machine body, and an electric slider is provided at the bottom, the mounting base is provided with a slide rail, the electric slider is installed on the slide rail, and the regulator is provided with an adjustment switch and a display screen. The utility model can observe the discharge port and the stone discharge port through the display screen, which is convenient for adjusting the inclination angle and air volume.

[0004] However, although the above technical solution can prevent the de-stoner from falling over when it is working, it does not have a quantity control function when wheat enters the de-stoner through the feed port. The feed impact speed is too fast, causing wheat to pile up and the screening speed cannot keep up, affecting the de-stoner effect. Therefore, the de-stoner does not have a shock absorbing mechanism, and the de-stoner will generate vibration during operation, which is transmitted to the entire machine body. For a long time, it will cause damage to the de-stoner parts and reduce the service life. To this end, we propose a wheat de-stoner anti-falling device to solve the above problems.
