[0005] Therefore, it is necessary to design a waste material recycling and environmentally friendly crushing device that is highly practical and has good environmental performance. Summary of the invention

[0013] When the materials need to be crushed by the crushing roller, the bottom groove and the top groove arranged on the top of the crushing shell can ensure that the dust generated in the crushing process will not fly out from the top of the crushing shell, thereby protecting the air and achieving a good environmentally friendly crushing purpose. At the same time, due to the crushing of objects of different volumes, the fastening button can be loosened with the cooperation of the arc plate to allow the top groove to be flipped, increasing the opening size between the top groove and the bottom groove, so as to adapt to the crushing of materials of larger volumes.

[0015] During the process of material crushing, the external water pipes and water inlet pipes of the material feed ports of the top trough and the bottom trough are connected. At this time, clean water is transported to the dust reduction pipe, and then atomized and sprayed to the material feed ports of the top trough and the bottom trough through the nozzle, thereby achieving the purpose of atomization dust reduction, and further preventing the dust from flying into the air during the material crushing process, thereby achieving the purpose of environmentally friendly crushing.

[0016] According to the above technical solution, the power assembly includes a power box, which is fixedly connected to the left side of the top of the base. The first rotating shaft, the second rotating shaft and the third rotating shaft are rotatably connected in sequence from back to front in the power box. The first rotating shaft is fixedly connected to the first gear at both ends in the power box, the second rotating shaft is fixedly connected to the second gear at both ends near the middle of the power box, the third rotating shaft is fixedly connected to the third gear corresponding to the second gear in the power box, and the outer wall of the second rotating shaft is fixedly connected to the protective gear corresponding to the first gear.

[0019] When the first motor applies sufficient power to the first rotating shaft through the pulley assembly, the power gear can be fully transmitted to the crushing shaft under the cooperation of the first gear, the second gear, the protective gear and the third gear. The crushing shaft crushes and recycles the materials through the crushing roller. However, when the crushed material is hard, because the spring bar cooperates with the elasticity, when the inner gear ring continues to transmit the power of the first motor and the inner ring is hindered by the hard material, the spring bar contracts when it receives the pulling force between the first motor and the hard material, causing the limit block and the protruding block to jump, so that the crushing roller can be buffered, forming a certain protection effect on the crushing roller, and at the same time protecting the shaft and gears between the motor and the transmission components.

[0020] According to the above technical scheme, the dust screening assembly includes a track, which is fixedly connected to the falling groove at the top inner side of the base, a screen plate is slidably connected to the inner side of the track, a reset plate is fixedly connected to the front side of the screen plate, a sliding rod is slidably connected to the middle of the reset plate, a third mounting block is fixedly connected to the front end of the sliding rod, the top of the third mounting block is fixedly connected to the top inner side of the base, an arc block is fixedly connected to the rear side of the screen plate, a cam is arranged on the front side of the arc block, a power shaft is fixedly connected to the middle of the cam, one end of the power shaft is rotatably connected to the base, and the other end of the power shaft is rotatably connected to the second mounting block, the top of the second mounting block is fixedly connected to the top inner side of the base, and a second motor is fixedly connected to the outer side of the second mounting block corresponding to the power shaft.

[0021] When the crushed small particles fall into the drop groove along with the dust, the second motor starts and drives the power shaft and the cam to rotate continuously. The rotating cam continuously pushes the screen plate with the cooperation of the arc block, so that the screen plate moves forward in the track. Therefore, with the cooperation of the second spring and the third mounting block, when the arc block and the cam are in contact at a short distance, the second spring resets the position of the screen plate. When the arc block and the cam are in contact at a long distance, the screen plate is pushed forward, so that the screen plate forms a good reciprocating motion, thereby continuously sifting the dust into the dust collection shell, so that the dust will not fly into the air due to the vibration of falling during the continuous falling process, thereby further achieving the purpose of environmental protection crushing.

[0022] According to the above technical solution, the second motor is equipped with an output shaft, and the second motor is fixedly connected to the power shaft via the output shaft, so as to ensure that sufficient power of the second motor acts on the power shaft.

[0023] According to the above technical solution, the dust cover includes a dust shell, the dust shell is fixedly connected to the top of the base, the bottom of the dust shell is fixedly connected to a bottom plate, and the middle of the bottom of the bottom plate is fixedly connected to a dust pipe. The fallen dust falls into the dust shell due to the sieving of the sieve plate. At this time, the dust pipe is connected to an external industrial vacuum cleaner, and the dust can be quickly transported to the industrial vacuum cleaner. At the same time, the suction force generated by the industrial vacuum cleaner can further prevent the dust from flying around, thereby further achieving the purpose of environmentally friendly crushing.

[0024] According to the above technical solution, the dust screening assembly is arranged in the dust collecting shell, and a notch is provided at the rear side of the dust collecting shell corresponding to the arc block and the cam. The notch design can protect the cam from being blocked by the dust collecting shell when it continuously pushes the arc block to reciprocate, thus ensuring the good and continuous operation of the whole device.

[0025] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0026] 1. The present invention is provided with a protection mechanism. When the first motor applies sufficient power to the first rotating shaft through the pulley assembly, the power gear can be sufficiently transmitted to the crushing shaft under the cooperation of the first gear, the second gear, the protection gear and the third gear. The crushing shaft crushes and recycles the materials through the crushing roller. However, when the crushed material body is hard, because the spring bar cooperates with the elasticity, when the inner gear ring continues to transmit the power of the first motor and the inner ring is hindered by the hard material, the spring bar contracts when receiving the pulling force between the first motor and the hard material, so that the limit block and the protruding block jump, so that the crushing roller can be buffered, forming a certain protection effect on the crushing roller, and at the same time protecting the shaft and gears between the motor and the transmission component.

[0027] 2. The present invention is provided with a covering assembly. When the materials need to be rotated and crushed by the crushing roller, the bottom groove and the top groove arranged on the top of the crushing shell can ensure that the dust generated during the crushing process will not fly out from the top of the crushing shell, thereby protecting the air and achieving a good environmentally friendly crushing purpose. At the same time, because of the crushing of objects of different volumes, the fastening button can be loosened with the cooperation of the arc plate, so that the top groove can be flipped to increase the opening size between the top groove and the bottom groove, so as to adapt to the crushing of materials of larger volumes.

[0028] 3. The present invention is provided with a dust reduction component. During the process of material crushing, the external water pipes and water inlet pipes of the material feed ports of the top trough and the bottom trough are connected. At this time, clean water is transported to the dust reduction pipe, and then atomized and sprayed to the material feed ports of the top trough and the bottom trough through nozzles, thereby achieving the purpose of atomization dust reduction, and further preventing dust from flying into the air during the material crushing process, thereby achieving the purpose of environmentally friendly crushing.

[0029] 4. The present invention is provided with a dust screening component. When the crushed small particles fall into the falling groove along with the dust, the second motor is started to drive the power shaft and the cam to rotate continuously. The rotating cam continuously pushes the sieve plate in cooperation with the arc block, so that the sieve plate moves forward in the track. Therefore, in cooperation with the second spring and the third mounting block, when the arc block and the cam are in contact at a short distance, the second spring resets the position of the sieve plate. When the arc block and the cam are in contact at a long distance, the sieve plate is pushed forward, so that the sieve plate forms a good reciprocating motion, thereby continuously screening the dust into the dust collection shell. Therefore, in the process of continuous falling, the dust will not fly into the air due to the vibration of falling, thereby further achieving the purpose of environmentally friendly crushing.

[0030] 5. The present invention is provided with a dust hood, and the fallen dust falls into the dust shell due to the sieving movement of the screen plate. At this time, the dust suction pipe is connected to the external industrial vacuum cleaner, and the dust can be quickly transported to the industrial vacuum cleaner. At the same time, the suction force generated by the industrial vacuum cleaner can further prevent the dust from flying around, thereby further achieving the purpose of environmentally friendly crushing.

[0060] By providing the dust screening component 62, when the crushed small particles fall into the falling groove 525 along with the dust, the second motor 622 is started to drive the power shaft 623 and the cam 624 to rotate continuously, and the rotating cam 624 continuously pushes the sieve plate 627 with the cooperation of the arc block 625, so that the sieve plate 627 moves forward in the track 626, so that with the cooperation of the second spring 6291 and the third mounting block 6292, when the arc block 625 and the cam 624 are in contact at a short distance, the second spring 6291 resets the position of the sieve plate 627, and when the arc block 625 and the cam 624 are in contact at a long distance, the sieve plate 627 is pushed forward, so that the sieve plate 627 forms a good reciprocating motion, thereby continuously screening the dust into the dust collection shell 611, so that the dust will not fly into the air due to the vibration of falling in the process of continuous falling, and the purpose of environmental protection crushing is further achieved.

[0063] By providing a dust hood 61, the fallen dust falls into the dust shell 611 due to the sieving movement of the screen plate 627. At this time, the dust pipe 613 is connected to the external industrial vacuum cleaner, and the dust can be quickly transported to the industrial vacuum cleaner. At the same time, the suction force generated by the industrial vacuum cleaner can further prevent the dust from flying around, thereby further achieving the purpose of environmentally friendly crushing.

[0064] When in use, when the first motor 2 transmits sufficient power to the first rotating shaft 413 through the pulley group 3, the power gear can be fully transmitted to the crushing shaft 522 under the cooperation of the first gear 412, the second gear 415, the protection gear 42 and the third gear 417. The crushing shaft 522 crushes and recycles the materials through the crushing roller 524. However, when the crushed material body is hard, because the spring strip 424 cooperates with the elasticity, when the inner gear ring continues to transmit the power of the first motor 2 and the inner ring 422 is hindered by the hard material, the spring strip 424 contracts when it receives the pulling force between the first motor 2 and the hard material, allowing the limit block 423 and the protruding block 425 to jump, so that the crushing roller 524 can be buffered, forming a certain protection effect on the crushing roller 524, and at the same time protecting the shaft and gears between the motor and the transmission components.

[0065] When the materials need to be rotated and crushed by the crushing roller 524, the bottom groove 512 and the top groove 518 arranged on the top of the crushing shell 521 can ensure that the dust generated during the crushing process will not fly out from the top of the crushing shell 521, thereby protecting the air and achieving a good environmentally friendly crushing purpose. At the same time, due to the crushing of objects of different volumes, the fastening button 513 can be loosened with the cooperation of the arc plate 516, so that the top groove 518 can be turned over to increase the opening size between the top groove 518 and the bottom groove 512, so as to adapt to the crushing of materials of larger volumes.

[0066] During the process of material crushing, the external water pipe and the water inlet pipe 531 of the material feed outlet of the top trough 518 and the bottom trough 512 are connected. At this time, clean water is transported to the dust reduction pipe 533, and then atomized and sprayed to the material feed outlet of the top trough 518 and the bottom trough 512 through the nozzle 534, thereby achieving the purpose of atomization dust reduction, and further preventing dust from flying into the air during the material crushing process, thereby achieving the purpose of environmentally friendly crushing.

[0067] When the crushed small particles fall into the falling groove 525 along with the dust, the second motor 622 starts to drive the power shaft 623 and the cam 624 to rotate continuously. The rotating cam 624 continuously pushes the sieve plate 627 with the cooperation of the arc block 625, so that the sieve plate 627 moves forward in the track 626. Therefore, with the cooperation of the second spring 6291 and the third mounting block 6292, when the arc block 625 and the cam 624 are in contact at a short distance, the second spring 6291 resets the position of the sieve plate 627. When the arc block 625 and the cam 624 are in contact at a long distance, the sieve plate 627 is pushed forward, so that the sieve plate 627 forms a good reciprocating motion, thereby continuously sifting the dust into the dust collection shell 611, so that the dust will not fly into the air due to the vibration of falling in the process of continuous falling, and the purpose of environmental protection crushing is further achieved.

[0068] The fallen dust falls into the dust collection shell 611 due to the sieving movement of the screen plate 627. At this time, the dust collection pipe 613 is connected to the external industrial vacuum cleaner, and the dust can be quickly transported to the industrial vacuum cleaner. At the same time, the suction force generated by the industrial vacuum cleaner can further prevent the dust from flying around, thereby further achieving the purpose of environmentally friendly crushing.
