[0030] As Figures 1 to 5 shown, the biological substrate particle screening device of the present invention includes: a crushing mechanism 1 for crushing the biological substrate and a screening mechanism 2 for screening the biological substrate. After being crushed by the crushing mechanism 1, the material enters the screening mechanism 2 through a hopper for screening.

[0031] The crushing mechanism 1 includes: a crushing frame 11, a support mesh 12 fixedly installed inside the crushing frame 11, and a crushing roller 13 rotatably installed on the crushing frame 11. One end of the crushing roller 13 is connected with a pulley 14, and the other end of the crushing roller 13 is connected with a counterweight wheel 15.

[0032] The pulley 14 is connected to a crushing motor through a belt, so that the crushing motor drives the crushing roller 13 to rotate, thereby crushing materials such as straw. The crushed material passes through the support mesh 12 and enters the screening mechanism 2 for screening.

[0033] An air purification mechanism 16 is installed on the crushing frame 11. A large amount of dust is generated during crushing, and the air purification mechanism 16 can filter the dust to purify the air. The air purification mechanism 16 used in this application is a mature existing design, so it will not be elaborated here.

[0034] In this application, a plurality of support rods 17 are detachably connected to the crushing frame 11. The plurality of support rods 17 form a support surface. A crushing block 18 is fixedly installed on the crushing roller 13, and the crushing block 18 can pass through the gap between two support rods 17, thereby crushing straw.

[0035] The screening mechanism 2 includes: a screen frame 21; a first screen 22 and a second screen sequentially installed on the screen frame 21; a transverse movement plate 23 located above the first screen 22; and a motor 24 that drives the screen frame 21 to swing; a crankshaft 25 is connected to the output shaft of the motor 24, and the crankshaft 25 is connected to the bottom of the screen frame 21.

[0036] In this application, the motor 24 drives the crankshaft 25 to rotate, and during the rotation of the crankshaft 25, the screen frame 21 is driven to swing.

[0037] Here, it should be specifically explained that the crankshaft 25 includes a shaft portion 251 and sector blocks 252. A connecting shaft is fixedly provided between the two sector blocks 252. A connecting block 253 is fixedly connected to the bottom of the screen frame 21. The connecting block 253 is located between the two sector blocks 252, that is, the connecting shaft passes through the connecting block 253 and is in sliding contact with the connecting block 253. The connecting shaft and the shaft portion 251 are eccentrically arranged. Four sector blocks 252 are provided in this application, and two connecting blocks 253 are provided. The two connecting blocks 253 are arranged at both ends of the screen frame 21.

[0038] A material distribution frame 26 is fixedly connected to the tail of the screen frame 21. The screen frame 21 is inclined, and the material distribution frame 26 is horizontally placed. A material distribution plate 27 is fixedly connected to the material distribution frame 26. A plurality of material distribution plates 27 are provided. The material distribution plates 27 are fixedly connected to the inside of the material distribution frame 26. The material distribution plates 27 are located at the tails of the first screen 22 and the second screen. When screening biological substrate particles, large-particle biological substrates do not pass through the first screen 22 and flow onto the material distribution plate 27. A material collection device can be arranged downstream of the material distribution plate 27 to collect unqualified materials, and qualified materials are also discharged through the bottom plate of the material distribution frame 26.

[0039] A fixed shaft 28 is fixedly connected to the screen frame 21, and a limiting component for moving it is connected to the fixed shaft 28; the limiting component includes: a fixed rod 29, a sleeve rod 210 sleeved on the fixed rod 29, a limiting plate 211 fixedly connected to the end of the sleeve rod 210, a moving block 212 is installed on the limiting plate 211, and the fixed shaft 28 passes through the moving block 212 and is in sliding contact with the moving block 212.

[0040] The motor 24 drives the crankshaft 25 to rotate. During the rotation of the crankshaft 25, the sieve frame 21 is driven to swing. During this process, the fixed shaft 28 causes the sleeve rod 210 to move downward on the fixed rod 29. A first spring is sleeved on the fixed rod 29, and the first spring contacts the sleeve rod 210. The first spring can push the sleeve rod 210 to reset, so that the fixed rod 29 and the sleeve rod 210 can limit the movement of the fixed shaft 28 in the vertical direction.

[0041] As a further improvement of the present invention, a guide groove 213 is fixedly connected to the limiting plate 211. The guide groove 213 is an inverted T-shaped groove. The lower end of the moving block 212 is buckled in the guide groove 213 and is in sliding contact with the guide groove 213. During the swinging of the sieve frame 21, the moving block 212 will continuously move along the guide groove 213, so as to limit the movement of the fixed shaft 28 in the horizontal direction.

[0042] A cover body 214 is fixedly installed on the sieve frame 21. A through groove 215 is opened on the cover body 214. A contact plate 216 with an inclined surface is fixedly connected to the limiting plate 211. A connecting rod 217 is fixedly connected to the transverse moving plate 23. The end of the connecting rod 217 is connected with a universal ball 218, and the universal ball 218 abuts against the contact plate 216.

[0043] In the present invention, a plurality of material plates 231 are fixedly connected to the transverse moving plate 23. When the universal ball 218 rolls on the contact plate 216, the transverse moving plate 23 will move, thereby driving the material plates 231 to move, so as to stir the strip-shaped materials on the first sieve 22 and make them move downward along the first sieve 22 until they move onto the material dividing plate 27.

[0044] It should be supplemented here that in order to make the transverse moving plate 23 reciprocate, an elastic member is provided at one end of the transverse moving plate 23 to make the transverse moving plate 23 reset. That is, a transverse moving rod 219 is fixedly connected to the transverse moving plate 23. A bushing 220 is fixedly installed on the cover body 214. The transverse moving rod 219 is inserted into the bushing 220 and is in sliding contact with the bushing 220. A second spring 221 is installed in the bushing 220, and the second spring 221 contacts the transverse moving rod 219. So that the second spring 221 can push the transverse moving rod 219 to move.

[0045] The connecting rod 217 passes through the through groove 215 and is in sliding contact with the cover body 214, so that the connecting rod 217 can move in the through groove 215. On the one hand, it plays a supporting role through the connecting rod 217; on the other hand, it can play a limiting role.

[0046] Working principle:

[0047] The crushing motor 24 drives the crushing roller 13 to rotate, so as to crush straw and the like; the crushed material passes through the support net 12 and enters the screening mechanism 2 for screening; the motor 24 drives the crankshaft 25 to rotate, driving the sieve frame 21 to swing; on the one hand, the material moves along the first sieve 22, the second sieve or the bottom plate of the sieve frame 21, and on the other hand, when the universal ball 218 rolls on the abutting plate 216, the transverse movement plate 23 will move, thereby driving the inner material plate 231 to move, so as to stir the strip-shaped material on the first sieve 22 and make it move downward along the first sieve 22; preventing the material from piling up on the first sieve 22.

[0048] The standard parts used in the present invention can all be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, welding, etc. that are mature in the prior art. The machinery, parts and equipment all adopt conventional models in the prior art. Coupled with the circuit connection adopting the conventional connection method in the prior art, it will not be elaborated here. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
