Pretreatment device for mixing straw auxiliary materials

Abstract

The invention provides a pretreatment device for mixing straw auxiliary materials. The pretreatment device comprises a mixer main body, the top of the mixer main body is fixedly provided with a pretreatment bin, the top of the pretreatment bin is fixedly connected with a feed chute, the outer side of the pretreatment bin is provided with a vent hole, the vent hole is internally provided with a filter screen, an air draft mechanism corresponding to the vent hole is installed on the mixer main body, and symmetrically-arranged compression roller pieces are rotationally installed in the pretreatment bin. When the incomplete tooth section on an inner gear ring is separated from a connecting gear set, a middle ring and an inner rotating shaft generate relative displacement, a third magnetic block and a first magnetic block are aligned, under the action of homopolar repulsion, a collision block is pushed to collide with an extrusion roller outwards, dust attached to the extrusion roller is vibrated off, then a wedge-shaped plate is in contact with a movable rod, the movable rod is extruded to move outwards, so that a second magnetic block is in contact with a magnetic conductive ring, after the magnetic conductive ring is magnetized, the collision block is pushed to reset, the function of continuously cleaning the extrusion roller is achieved through the circulation, the structure issimple, and use is convenient.

Description

technical field [0001] The invention belongs to the technical field of mixing agricultural auxiliary materials, in particular to a pretreatment device for mixing straw auxiliary materials. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops. In the cultivation of crops such as wheat, corn, sugarcane and cotton, after the seeds are harvested, the remaining straw is rich in nitrogen, phosphorus, potassium, calcium, Magnesium and organic matter are renewable resources, which can not only be used as supplementary materials for breeding feed, but also as supplementary materials for Chinese medicine decoction pieces. Therefore, these straws are generally reprocessed now. [0003] In the process of processing straw as an auxiliary material, the general steps are to clean up the straw first, then put it into the mixer, cut or chop it, mix it with other raw materials, and finally process it into various products. The straw is taken...

Problems solved by technology

[0003] In the process of processing straw as an auxiliary material, the general steps are to clean up the straw first, then put it into the mixer, cut or chop it, mix it with other raw materials, and finally process it into various products. The straw is taken out from the soil, and it is inevitable that the straw will be stained with soil. In many processing procedures, in order to ensure the quality of the straw, the straw cannot be washed and cleaned, which makes it difficult to clean the straw completely. In the straw in the mixer, some soil still adheres to some extent, which reduces the quality of the subsequent processed products. Some devices for cleaning straw have a complex structure, and the cleaning device is easy to adhere to the soil, which is inconvenient to use.
