[0002] By 2022, the cotton planting area in Xinjiang is about 37 million mu, and the cotton yield accounts for more than 90% of the whole country. As a by-product of cotton production, about 20 million tons of cotton straw waste can be produced in Xinjiang every year, but the comprehensive treatment technology is relatively backward, and the utilization rate is less than 1 / 10, which causes great resource waste and leads to a series of problems such as environmental pollution and farmland pest and disease. Therefore, the utilization of cotton straw raw materials to produce high-value cotton straw flakeboard not only creates economic value, but also is a key measure to promote energy saving and emission reduction, and is a potential force to help China realize carbon peak and carbon neutralization.

[0032] The improvement lies in that the straw cutting device 1 is adopted, the feeding speed control and the cutter roller rotating speed control are synchronously and reversely linked to set the cutting step length, the cutter roller rotating speed is reduced, the cutting step length of the cutter disc acting on the cotton straw is maximized, and thus the length of the cotton straw is determined; the cutting-off cutter disc assembly 18 can cut the long straw into short straw with uniform length of 20-40mm according to the set cutting step length; the preparation of cotton straw raw materials with different sizes can be realized directly through the setting of the feeding speed and the cutter roller rotating speed, the equipment does not need to be replaced during shutdown, the production cost is low, and continuous production is facilitated.

[0033] Secondly, the specific structure of the vibrating magnetic separation device 2 is disclosed, which is to use vibration movement and strong magnetic field magnetic block as the magnetic source, remove the slag, fine sand and metal in the cotton straw through magnetic adsorption and vibration, including a vibrating mechanism 23 and a magnetic separation mechanism 24. The vibrating mechanism 23 includes a vibrating box 25, and eccentric excitation blocks 27 are symmetrically arranged on a transmission shaft 26 at the top of the vibrating box 25.

The transmission belt 21 of the magnetic separation mechanism 24 is connected with another transmission motor 28, which is arranged outside the magnetic separation mechanism 24. The fixed frame 30 is welded on the vibrating box 25.

[0034] The improvement lies in that after the material is put into the magnetic separation mechanism 24 from the discharging hopper 17 of the vibrating box 25, the metal in the straw raw material is adsorbed under the magnetic force of the electromagnetic plate in the sorting section; and the slag, fine sand and metal in the cotton straw are removed under the vibration force provided by the vibrating box 25. The slag, fine sand and metal in the cotton straw are repeatedly adsorbed and removed in the vibrating state, so that the quality of the cotton straw is gradually improved, and a solid foundation is laid for the high-grade cotton straw particle board product.

[0035] Secondly, the specific structure of the straw impurity removal device 3 is disclosed, which includes a primary picking spindle mechanism 31, a secondary picking spindle mechanism 32, a rotating brush 33 and an impurity removal box 34.

[0037] The improvement lies in that the roller pressing separation device 4 rolls the cotton stalks with the roller pressing wheel 41, so that the cotton stalks are flattened after being rolled, forming a flat structure similar to the flattened corn stalks, and in the later crushing process of the cutter, irregular fragmentation does not occur, thereby avoiding irregular fragmentation of the cotton stalks, changing the traditional form of the crushed cotton stalks, improving the combination with formaldehyde-free glue, and effectively separating the cotton stalks from the cotton core, greatly improving the removal rate of the cotton core and the quality of the raw materials, making them more suitable for application in the production of shaving board, facilitating the full use of cotton stalks, reducing the waste of cotton stalks, and improving the hardness performance of the shaving board.

[0038] The specific structure of the hammer mill crushing device 5 is disclosed again, including a hammer mill rack 43, a bottom support 44, a driving motor 12 located on the hammer mill rack, a hammer mill box shell 45, and a hammer mill device installed in the hammer mill box shell 45, the hammer mill device is in transmission connection with the driving motor 12 through a shaft coupling 46, the hammer mill box shell 45 is composed of two crushing chambers separated from each other, a feeding hopper 16 is installed above the hammer mill rack 43, a discharging hopper 17 is arranged at the bottom end of the hammer mill rack 43, and the bottom end of the hammer mill rack 43 is connected with the bottom support 44.

[0039] The improvement lies in that when the qualified material of the sieve enters the crushing box 70, it is first crushed by the shearing force of the high-speed moving hammer at the entrance, and when the geometric size of the material is smaller than the mesh size or width, the material is randomly discharged from the mesh, and the material that is not discharged continues to be further crushed by the shearing action of the high-speed moving hammer at the mesh edge. In this way, the material continuously entering the hammer mill is crushed under the repeated action of the high-speed moving hammer, and then continuously discharged from the mesh to achieve material crushing. The average thickness of the crushed cotton stalks prepared by the hammer mill crushing device is 0.7-1.0 mm, which can be used as the core material of the shaving board. Subsequently, the discharged material passes through the discharge port and is sent to the air separation device, thereby completing the screening and hammering process, thereby improving the polishing efficiency and separation speed.

The drying mechanism composed of the starting assembly 53 and the rotating assembly 54 cooperates with the drying mechanism composed of the arc-shaped discharging assembly 57 and the blowing assembly 56.

[0042] The improvement lies in that, in use, the water-passed straw raw materials are put into the inner cavity of the dehydration cylinder 51. The rotating assembly 54 starts the double-shaft motor 71 to drive the rotating rod 72 to rotate and further drive the transmission gear disc 73 to rotate. The transmission gear disc 73 is engaged with the gear ring to drive the control ring to rotate in the ring groove. The blowing assembly 56 pushes the straw raw materials to move in the dehydration cylinder to the arc-shaped discharging assembly 57.
