[0027] like Figure 1 As shown, the cotton straw pulverizing device of the present invention mainly includes a tearing device 1, a breaking device 2, a container 3, a screen 4 and a bracket 5 and other main components.

[0028] 1. Shredding device 1( Figure 2 )

[0029] The shredding device 1 performs preliminary tearing of the cotton straw through the relative movement of two moving knives 11. The moving knife 11 is driven by a motor 13 and rotated by a reducer 12. The power of the motor 13 can be adjusted according to the thickness of the straw to ensure efficient operation of the equipment. The structure of the shredding device adopts an adjustable gap design, and the gap of the moving knife 11 can be adjusted according to actual needs to adapt to cotton straws of different thicknesses. The straw enters the shredding device through the feed port 15, and is torn by the relative movement of the moving knife. The shredded material is sent out from the discharge port 14 and enters the crushing device 2.

[0030] 2. Breaking device 2 ( Figure 3 )

[0031] The crushing device 2 is composed of a motor 22, a reducer 21, a transmission shaft 23, a crushing rod 24 and a protective cover 25. The motor 22 drives the reducer 21, and the transmission shaft 23 is driven to rotate through the transmission of the reducer, thereby driving multiple crushing rods 24 to further crush the shredded straw. The crushing rods 24 are usually spiral-shaped or other shapes suitable for crushing straw, and can be replaced or adjusted as needed. The crushing rods 24 hit and twist the straw during rotation, so that it is further crushed into smaller particles. The crushed material is screened through the screen 4 below, and the material with smaller particles enters the container 3 through the screen. The setting of the protective cover 25 can effectively prevent material splashing or accidental touch by personnel to ensure safety.

[0032] 3. Screen 4

[0033] The screen 4 is located below the crushing device 2 and is used to screen the crushed materials. The aperture of the screen can be adjusted or replaced as needed to screen crushed materials of different particle sizes to ensure particle uniformity. The screened materials enter the container 3 for collection. The design of the screen helps to ensure that the distribution of particles meets the requirements and avoids excessively large particles affecting subsequent use.

[0034] 4. Container 3 and pulley device 31

[0035] The container 3 is used to collect the crushed materials after screening. A discharge port is provided at the bottom of the container 3 to facilitate the discharge and storage of the materials. A pulley device 31 is provided below the container 3 so that the container can be easily moved in the working area. The pulley device 31 has good flexibility, and the container 3 can move freely in multiple directions, which is convenient for the collection and transfer of the crushed materials.

[0036] 5. Bracket 5

[0037] The bracket 5 is used to support the shredding device 1, the crushing device 2, the screen 4 and the container 3, etc., to ensure that each part is fixed firmly and the stable operation of the equipment is ensured. The height and structure of the bracket 5 can be adjusted according to actual needs to adapt to different working environments.

[0038] 6. Workflow

[0039] When cotton straw enters the shredding device 1 through the feed port 15, the moving knife 11 performs preliminary tearing of the straw by relative rotation. The shredded material is fed into the shredding device 2 through the discharge port 14, where the shredding rod 24 driven by the motor 22 further strikes and shreds the shredded straw to form smaller particles. The shredded material is screened through the screen 4, and the smaller particles enter the container 3 for collection. The container 3 can be easily moved to different positions through the pulley device 31, which is convenient for the storage and subsequent processing of the shredded material.
