[0015] Beneficial Effects

[0016] 1. According to the recycling and crushing device of each embodiment of the present invention, the crushing mode can be freely selected, which is more practical, can realize centrifugal expansion, enhance the crushing effect, and can realize the crushing and separation filtration of secondary recycled materials without manual operation, which is more labor-saving and saves labor costs.

[0017] 2. By setting up a two-stage propulsion device, graded filtration can be achieved through linkage, which can make it easier to recover large particles and facilitate the transportation of the recycling device. The collection block and the collection filter plate can make it easier to collect and recover materials, and the driving structure has stronger linkage. At the same time, in the process of pushing large particles, it can assist in filtering qualified particles in the large particles again and drop them into the finished product drawer, and at the same time assist in scraping the collection filter plate for cleaning. At the same time, the recovery device can assist in conveying large particles, which is more labor-saving and more efficient. It can help improve practicality and effectively reduce labor costs. The entire propulsion and transportation process can be achieved through linkage, and the linkage motor is engaged at the same time during rotation. The driving worm gear set for driving can realize driving the transmission main shaft to rotate. During the rotation of the transmission main shaft, the transmission bevel gear at the bottom meshes to drive the reciprocating screw to rotate. The reciprocating screw with bidirectional thread can realize driving the propulsion slider to slide back and forth, so as to push the large particles to the collection hole on the collection block. At the same time, the propulsion slider with the rear inclined surface structure can avoid material obstruction when sliding to the left, and is more convenient for resetting and sliding. During the rotation of the transmission main shaft, the transmission pulley can drive the conveying auger on the recovery connecting pulley to rotate through the pulley belt, so as to realize the recovery of the material on the collection block, and then discharge it to the crushing device through the discharge port for secondary crushing. The overall use is more convenient, and the operation method is simple, the service life is long, and the linkage is strong.

[0018] 3. By setting a centrifugal expansion device in conjunction with a transmission device, it is possible to expand the knocking plate under the action of centrifugal force. By using the knocking plate for knocking and crushing, the crushing effect is better and the particles are smaller. At the same time, another important function of setting a centrifugal expansion device is that it can assist in improving the overall use effect. It can avoid blockage when only the crushing device is used for crushing. At the same time, it can provide an elastic buffer force, which can greatly reduce the subsequent failure rate. It also helps to improve the wear resistance effect. The overall structure is mature and stable, and it is easier to use. It can be fully linked with the transmission device set, and it is more flexible to use. Under the drive of the linkage motor, the centrifugal mounting barrel is driven to rotate. In this process, the centrifugal mounting barrel has a strong centrifugal force, and the knocking plate can be centrifugally "thrown out". At the same time, the knocking plate can be knocked and crushed after it slides out, thereby improving the crushing effect.

[0019] 4. By setting up an independent crushing device and installing a supporting device, rapid coarse crushing can be achieved, and the crushing efficiency is higher. At the same time, the whole can provide two crushing effects. By only starting the drive motor, the two crushing rollers can be driven for rough processing and high-speed crushing. The steel-rolled crushing roller will also be more wear-resistant. Fine crushing can be achieved in conjunction with a centrifugal expansion device. By setting up a drive device, the drive can be achieved. The overall use is more flexible and more in line with the actual crushing work needs. It can not only ensure the crushing efficiency, but also control the crushing quality. The overall use is more practical. The set linkage motor can drive the centrifugal expansion device while driving the large particle material and driving the recovery. The overall use is more efficient and the operation is simpler. The fast crushed material can be taken out by pulling the material taking door, and the finely filtered small particle material can be taken out by pulling the finished product drawer.
