Technical Field

[0001] This utility model relates to the field of crushing and grinding technology, specifically a crushing and grinding device used for the recycling and processing of waste rubber tires. Background Technology

[0002] As we all know, discarded rubber tires are known as "black pollution." The accumulation of large amounts of waste tires not only occupies land but also seriously damages the environment. my country produces the largest amount of waste tires in the world every year. Therefore, my country has huge potential for recycling and reusing waste rubber tires. Due to the unique wear resistance, aging resistance, water resistance, and shock absorption properties of tire rubber, the treatment of waste tires mainly focuses on rubber granules and rubber powder. These two are widely used in modified asphalt, waterproof materials, rubber paving stones, and rubber running tracks.

[0003] A search revealed that a utility model patent with Chinese patent authorization announcement number CN215849125U discloses a crushing and grinding device for recycling waste rubber tires. The device includes a motor and a powerful blower. The left end of the powerful blower is fixedly connected to a grinding mill.

The screen plate 8 is welded to the top of the sliding strips 7. By fixing the screen plate 8 to the sliding strips 7, the screen plate 8 is kept sliding along the first sliding groove 3. An extension plate 9 is welded to one side of the screen plate 8 and to the top of the sliding strips 7. The shape of the extension plate 9 is adapted to the first through hole 2. When the screen plate 8 slides, the extension plate 9 slides, and the crushed waste rubber falls out. When it reaches the extension plate 9, it will scrape off the waste rubber on the first through hole 2 as it slides, so that the waste rubber enters the screen plate 8 for screening. The collection plate 10 is welded to the other side of the screen plate 8 and the top of the slide bar 7. The collection plate 10 is mainly used to screen unqualified rubber dust and make the unqualified rubber dust undergo secondary grinding.

The rotation of the first pulley 21 drives the first rotating column 17 on one side to rotate. The rotation of the first rotating column 17 on one side drives the first gear 19 to rotate. At the same time, the grinding blade 18 on one side rotates. The rotation of the first gear 19 drives the second gear 20, which meshes with the first gear 19, to rotate. The rotation of the second gear 20 drives the first rotating column 17 on the other side to rotate, causing the grinding blade 18 on the other side to rotate.

The output shaft of the third motor 36 is fixed to the bottom of the auger 30. The rotation of the third motor 36 drives the auger 30 to rotate, and the rotation of the auger 30 transports the unqualified rubber powder.

[0044] Then, refer to Figure 12 In this embodiment, an auxiliary component 37 is also included.

[0046] Working principle:

[0047] The crushing and grinding device used for recycling and processing waste rubber tires is operated as follows: First, the device is placed in the desired location. Then, the second motor 23 is started. The second motor 23 rotates, driving the second pulley 24 to rotate. The rotation of the second pulley 24, via the belt 25, drives the first pulley 21 to rotate. The rotation of the first pulley 21 drives the first rotating column 17 on one side to rotate. The rotation of the first rotating column 17 on one side drives the first gear 19 to rotate. Simultaneously, the grinding blade 18 on one side rotates. The rotation of the first gear 19 drives the second gear 20, which meshes with the first gear 19, to rotate. The rotation of the second gear 20 drives the first rotating column 17 on the other side to rotate, causing the grinding blade 18 on the other side to rotate. The grinding blades 18 work together to crush the waste rubber tires. Then, the device is activated. The first motor 13 is activated, which drives the first fixed rod 14 to rotate. The rotation of the first fixed rod 14 causes the first rotating rod 15 to swing, causing the extension plate 9 to slide. Since the screen plate 8 is fixed on the slide bar 7, the screen plate 8 slides along the first slide groove 3. The high-speed rotation of the first motor 13 drives the extension plate 9 to shake rapidly, achieving vibration. Due to the inclined design of the screen plate 8, the unqualified rubber powder moves to the other side, allowing the rubber powder to slowly enter the transmission pipe 29 from the collection plate 10. Next, the third motor 36 is activated, which drives the auger 30 to rotate. The auger 30 rotates to transport the unqualified rubber powder, allowing it to undergo secondary grinding. The qualified rubber powder passes through the screen plate 8 and enters the collection basket 43. After crushing, the worker pulls the handle 44 to collect the rubber powder.
