A pulverizing blade 5 for secondary pulverizing the waste rubber is arranged in the second pulverizing chamber 2, and the material falling into the second pulverizing chamber 2 is pulverized again by the setting of the pulverizing blade 5, thereby improving its pulverizing efficiency. The inside of the second crushing chamber 2 is symmetrically provided with a baffle plate 6 for blocking the feed port 3. The setting of the baffle plate 6 can effectively prevent too much material from being fed at one time, which would affect the crushing effect; the inside of the second crushing chamber 2 is provided with a sieve plate 7 for screening the crushed waste rubber. The sieve plate 7 is penetrated by a plurality of sieve holes, and the aperture of the sieve holes can be set according to demand, so that the qualified crushed material can pass through the sieve plate 7.

[0034] The second crushing chamber 2 is provided with a driving mechanism 8, which drives the crushing blade 5 and the screen plate 7 to rotate. During the operation of the driving mechanism 8, the two material baffle plates 6 are driven to fit intermittently through the transmission connection component 9, so as to intermittently block the bottom of the feed port 3, so as to achieve the purpose of intermittent material discharge, effectively prevent the accumulation of materials, improve the crushing efficiency, and make the crushing more complete; and drive the crushing blade 5 and the screen plate 7 to reciprocate in the vertical direction; when the crushing blade 5 reciprocates up and down, the material inside the second crushing chamber 2 can be stirred to improve its fluidity, and the crushing blade 5 can be moved to different heights at the same time, so as to improve the crushing efficiency of the material and make it have a better crushing effect; when the screen plate 7 reciprocates up and down, it can effectively prevent the material from clogging the sieve holes on its surface, thereby improving the service life of the screen plate 7 and its screening efficiency.

[0035] The driving mechanism 8 includes a driving rod 801 which is rotatably arranged inside the second crushing chamber 2, and a driving motor 803 is fixedly arranged at the bottom of the second crushing chamber 2, and the driving motor 803 is electrically connected to an external power supply; the output shaft of the driving motor 803 is fixedly arranged with the bottom end of the driving rod 801 through a coupling, and the top end of the driving rod 801 extends into the feed port 3 and is fixedly arranged with its inner surface, and a connecting rod 802 is slidably arranged on the outer surface of the driving rod 801, and the crushing blade 5 is fixedly arranged on the outer surface of the connecting rod 802, and the screen plate 7 is fixedly arranged at the bottom end of the connecting rod 802 and is sleeved on the outer surface of the driving rod 801.

Through the coordinated arrangement of the limiting groove 808 and the limiting protrusion 807, the connecting rod 802 can stably slide back and forth along the outer surface of the driving rod 801, thereby improving the stability of the connecting rod 802 during the movement process.

[0037] As a further technical solution, the outer surface of the driving rod 801 is fixedly provided with a supporting outer rod 804, the inner part of the supporting outer rod 804 is slidably provided with a supporting inner rod 805 extending to the outside thereof, the top of the supporting inner rod 805 is fixedly provided with a supporting column 806, and the baffle plate 6 is fixedly provided at the top of the supporting column 806;

[0038] A first guide groove is formed on the top of the supporting outer rod 804, and the supporting column 806 is formed through the first guide groove and is slidably arranged with the inner surface thereof. By setting the first guide groove, the moving direction of the supporting column 806 is limited, thereby improving the stability of the supporting column 806 during movement.

[0039] When the driving motor 803 is running, it drives the driving rod 801 to rotate, and the driving rod 801 drives the connecting rod 802 to rotate synchronously, so that the connecting rod 802 drives the crushing blade 5 and the screen plate 7 to rotate, the crushing blade 5 rotates to cut and crush the material, and the screen plate 7 rotates to prevent it from being blocked; when the driving rod 801 rotates, it drives the supporting outer rod 804 to rotate synchronously, the supporting outer rod 804 drives the supporting inner rod 805 to rotate, and the supporting inner rod 805 drives the material blocking plate 6 to rotate through the supporting column 806.

A transmission rod 905 is fixedly set on the outer surface of the transmission column 904, and the end of the transmission rod 905 is rotatably connected to the support inner rod 805. When the support outer rod 804 rotates, it drives the transmission gear 903 to rotate synchronously through the extension plate 902. At this time, with the cooperation of the transmission gear ring 901, the transmission gear 903 rotates synchronously, and the transmission gear 903 drives the transmission column 904 to rotate around its axis, so that the transmission column 904 pulls the end of the transmission rod 905 connected to it to also rotate around the axis of the transmission column 904.

When the opposite sides of the two baffle plates 6 are fitted, the bottom of the feed port 3 is blocked, thereby achieving the purpose of intermittent material unloading.

One end of the connecting elastic member 908 is fixedly provided with the transmission block 907; when the supporting inner rod 805 moves, the transmission ball 909 is driven to move synchronously by driving the L-shaped rod 906. When the transmission ball 909 gradually moves toward the direction close to the transmission block 907, When the transmission ball 909 moves, the transmission ball 909 contacts the inclined surface of the transmission block 907 and gradually squeezes the transmission block 907 to move downward, the connecting elastic member 908 is stretched, and when the transmission block 907 moves downward, it drives the connecting rod 802 to move downward, and the connecting rod 802 drives the crushing blade 5 and the screen plate 7 to move downward; when the transmission ball 909 gradually moves away from the transmission block 907, the thrust on the transmission block 907 is released, and the transmission block 907 is driven to move upward under the resetting action of the connecting elastic member 908, thereby driving the connecting rod 802 to move upward, so that the connecting rod 802 drives the crushing blade 5 and the screen plate 7 to move upward, thereby realizing the reciprocating movement of the crushing blade 5 and the screen plate 7 in the vertical direction, which not only improves the crushing range, but also effectively prevents the screen plate 7 from being blocked.

[0042] A second guide groove is formed through the bottom of the supporting outer rod 804, and the L-shaped rod 906 passes through the second guide groove and is slidably arranged with the inner surface thereof. The second guide groove can provide a moving space for the L-shaped rod 906, and limit its moving direction, thereby improving the stability of the L-shaped rod 906 during movement.

[0043] Among them, regarding the design of the baffle plate 6, an arc groove 601 is opened through the middle of the opposite sides of the two baffle plates 6, wherein, when the opposite sides of the two baffle plates 6 are in contact, the inner surface of the arc groove 601 contacts the outer surface of the driving rod 801 to prevent the two baffle plates 6 from being unable to fit together; the opposite sides of the two baffle plates 6 are conical in design, so that when the opposite sides of the two baffle plates 6 are in contact, if any material continues to fall into the second crushing chamber 2, it can be cut and crushed.
