Magnetic separator for removing stones and soil blocks from cereals and with environment protection function

Abstract

The invention discloses a magnetic separator for removing stones and soil blocks from cereals and with an environment protection function. The magnetic separator is provided with a machine frame, a workbench, a feeding hopper, a stone discharging hopper, a supporting spring plate, an inclination angle adjusting plate, a crank connecting rod driving device, a draught fan, an air adjusting hand wheel, a magnetic roller, a transmission roller, a power driving device driving the transmission roller to rotate, a conveying belt, a material distributing mechanism, a material distributing plate, an operation handle enabling the material distributing plate to rotate, a stone soil block collecting hopper and a clean material collecting hopper. The material distributing mechanism can conveniently separate stones and soil blocks mixed in the materials from the materials, and meanwhile, the soil blocks mixed in the materials are not prone to being broken in the material distributing mechanism. In the material distributing process, when soil blocks collide with the material distributing plate, the soil blocks are not prone to being broken due to the buffering effect of first elastic protrusionsand second elastic protrusions. The magnetic separator can separate stone and soil blocks with the same size and weight as cereals in the cereals, the stone and soil block removing effect is good, raised dust is reduced, the environment is protected, and the problem that an existing stone removing machine is poor in stone and soil block removing effect is solved.

Description

technical field [0001] The invention relates to a device for removing stones from cereals, in particular to a magnetic separator for removing stones from cereals and soil clods with the function of environmental protection. Background technique [0002] At present, the specific gravity de-stoner is widely used in grain de-stoning equipment, which is mainly used to separate the light specific gravity from the heavy specific gravity in the granular mixture, such as separating beans, melon seeds, sesame, rice, seeds, etc. Contains stones, clods, rice from detached rice seeds, etc. Existing specific gravity destoners have a general stone removal effect, and it is difficult to separate stones and soil clods that are equivalent in size and weight to cereals. [0003] The inventor retrieved the following relevant patent documents: CN106238205A discloses a magnetic separator, the feeding mechanism includes a feeding hopper; the first magnetic separation mechanism includes an auxili...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide an environmental-friendly grain separator for removing stones and soil clods, which can separate stones and soil clods in the cereals that are equivalent in size and weight to the grains. The effect of stones and soil clods is good, and it can reduce dust and protect the environment, so as to solve the problem of poor stone and soil removal effect of the current stone remover
