Agricultural fertilizer crushing and stirring device

Abstract

The invention discloses an agricultural fertilizer crushing and stirring device. The left end of a first motor is rotataby connected with a two-way threaded rod, the left end and the right end of thetwo-way threaded rod are in threaded connection with wedge-shaped blocks correspondingly, and supporting feet are fixedly connected to the upper ends of the wedge-shaped blocks. Threads of the left end and the right end of the two-way threaded rod are opposite in rotating direction and the same in thread pitch and lead. A sealing plate is arranged at the lower end of each wedge-shaped block, the ends of the sealing plates are hinged to the inner wall of a device body, and the upper ends of the sealing plates are fixedly connected with vertical support rods. Connecting rods are hinged to the lower ends of the sealing plates, and sliding blocks are hinged to the lower ends of the connecting rods and slidably connected with movable cavities. According to the agricultural fertilizer crushing and stirring device, through the first motor, the two-way threaded rod 5 is driven to conduct positive and negative rotation to drive the wedge-shaped blocks to move in the left-right direction to openand close the sealing plates intermittently to achieve intermittent material putting down, the lower ends of the sealing plates are provided with crushing wheels to crush a fertilizer put down intermittently, and the crushing effect is better through the intermittent crushing mode, so that the situation that the fertilizer is excessive and thus insufficiently crushed is avoided. According to theagricultural fertilizer crushing and stirring device, the structural design is reasonable and applicable, the fertilizer crushing quality is greatly improved, the labor force is saved, and the work efficiency is improved.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to an agricultural fertilizer crushing and stirring device. Background technique [0002] Fertilizer is a type of substance that provides one or more essential nutrients for plants, improves soil properties, and increases soil fertility. One of the material basis of agricultural production. As early as the Western Zhou Dynasty, China already knew that field weeds can promote the growth of millet after they rot. "Qi Min Yao Shu" introduced in detail the method of planting green manure and the method of crop rotation between leguminous crops and gramineous crops; it also mentioned the method of using crop stalks mixed with cow dung and urine, trampling and composting to make fertilizer . [0003] At present, most of the existing fertilizer mixing and crushing devices complete all the crushing work at one time. There is too much fertilizer in the device, and the crushing effect is not good...
