Description

Technical Field

[0001] This utility model belongs to the field of waste tire recycling technology, and specifically relates to a tire shredder. Background Technology

[0002] Promoting the recycling of waste tires can not only alleviate the shortage of rubber resources in my country, but also reduce "black pollution." The recycling process requires the use of shredders to process the waste tires.

[0003] While existing tire shredders can meet the basic requirements for shredding waste tires, some tire fragments can get stuck in the shredding structure. Since the existing shredding structure usually cannot move horizontally, meaning that it is not easy to move the two shredding components away from each other, workers cannot easily clear the tire fragments stuck on the shredding components from the top. Therefore, they cannot fully meet people's needs and will also affect the overall efficiency of tire shredding. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the existing technology by providing a tire shredder that not only meets the basic requirements for shredding waste tires, but also allows for flexible and convenient adjustment of the horizontal position of the shredding structure, enabling workers to easily clear tire fragments stuck on the shredding structure from above.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a tire shredder, including a base, a support on the base, a crushing box with an opening at the lower end through the support, a feed hopper on the top of the crushing box, two mounting brackets slidably arranged between the front and rear side walls of the crushing box, mounting shafts rotatably arranged on the two mounting brackets, crushing rollers arranged on the mounting shafts, and telescopic push rods arranged on the left and right sides of the crushing box, with the output shafts of the telescopic push rods connected to the mounting brackets.

[0006] As a further improvement of this utility model, a drive motor is respectively installed on each of the two mounting brackets. A drive gear is installed on the output shaft of the drive motor, and a driven gear meshing with the drive gear is installed on the mounting shaft. The drive motor drives the drive gear to rotate, and the drive gear then drives the driven gear to rotate, thereby driving the crushing roller to perform efficient crushing.

[0007] As a further improvement of this utility model, connecting grooves are respectively provided on the front and rear side walls of the crushing box, and connecting sliders that slide in contact with the connecting grooves are respectively provided on the two mounting brackets. Through the sliding engagement of the connecting grooves and connecting sliders, a sliding connection between the mounting brackets and the crushing box can be achieved.

[0008] As a further improvement of this utility model, guide slots are respectively provided on the left and right side walls of the crushing box, and guide plates that are inserted into the guide slots are provided on the mounting bracket. Locking bolts that can abut against the outer side wall of the guide plate and thus fix the connection between the guide slot and the guide plate are also screwed onto the guide slots.

[0009] As a further improvement of this utility model, a collection box with a conical lower end is fitted onto the lower end of the crushing box. A first extension plate is also provided on the side end of the crushing box, and a second extension plate is also provided on the side end of the collection box. A connecting spring is provided between the first extension plate and the second extension plate, and a vibration motor is also provided on the second extension plate. The crushed tire fragments are collected centrally through the conical collection box, facilitating subsequent processing and transportation. The vibration motor on the second extension plate can drive the collection box to vibrate, preventing fragment blockage and improving discharge efficiency.

[0010] As a further improvement of this utility model, a connecting slot is also provided on the second extension plate, and a connecting plate that is inserted into the connecting slot is also provided on the first extension plate. Through the insertion and cooperation of the connecting groove and the connecting plate, the collection box can maintain vertical vibration, avoid lateral displacement that would cause the crushing box and the collection box to collide and be damaged, and prevent the spring from being easily damaged by deformation.

[0011] As a further improvement of this utility model, a fastening plate is also provided on the base, and the fastening plate is also provided with fastening holes for installing anchor bolts. Through the cooperation of the anchor bolts, the fastening plate and the fastening holes, the device can be stably fixed on the ground.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Firstly, the horizontal position of the crushing rollers on the mounting frame can be easily adjusted via the telescopic push rod, allowing the two crushing rollers to be sequentially adjusted to be directly below the feed hopper. This enables workers to easily remove tire debris stuck on the crushing structure from above, improving the operability and maintenance efficiency of the equipment.

[0014] Secondly, the guide slots on the left and right side walls of the crushing box cooperate with the guide plates on the mounting frame, further enhancing the guiding performance of the mounting frame. At the same time, the connection between the guide slots and the guide plates is fixed by locking bolts, ensuring the reliability of the equipment during operation, preventing the mounting frame from sliding on its own, and thus preventing the telescopic push rod from being easily damaged.

Detailed Implementation

[0021] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0022] like Figure 1 , 2As shown, a tire shredder includes a base 101, a bracket 102 fixedly connected to the base 101, a crushing box 103 with an opening at the lower end passing through the bracket 102, a feed hopper 104 fixedly connected to the top of the crushing box 103, two mounting brackets 105 slidably arranged between the front and rear side walls of the crushing box 103, the mounting brackets 105 being U-shaped, mounting shafts 106 rotatably mounted on the two mounting brackets 105 respectively, bearings provided on the mounting brackets 105, the outer ring of the bearings being connected to the mounting brackets 105, the mounting shafts 106 being connected to the inner ring of the bearings and passing through the mounting brackets 105, a crushing roller 107 fixedly connected to the mounting shafts 106, telescopic push rods 108 fixedly connected to the left and right sides of the crushing box 103 respectively, the fixed end of the telescopic push rods 108 being connected to the outer side wall of the crushing box 103, the output shaft of the telescopic push rods 108 passing through the side wall of the crushing box 103 and connected to the mounting brackets, and the output shaft of the telescopic push rods 108 being connected to the mounting brackets 105.

[0023] The power unit (such as a motor) of the crushing roller 107 is started, causing the crushing roller 107 to begin rotating. After the waste tires enter the crushing box 103 through the feed hopper 104, they are clamped by the two relatively rotating crushing rollers 107 and crushed, and the waste tires are crushed into smaller pieces. The crushed tire pieces are discharged from the opening at the bottom of the crushing box 103, completing the entire crushing process.

[0024] The distance between the two crushing rollers 107 can also be changed by extending or shortening the output shaft of the telescopic push rod 108 by a certain length, thereby meeting the different crushing requirements of waste tires.

[0025] When it is necessary to clean the tire debris stuck on the crushing roller 107 from the feed hopper 104, the output shaft of the telescopic push rod 108 on one side can be shortened by a certain length to drive the corresponding mounting bracket 105 and crushing roller 107 away from the feed hopper 104. Then, the output shaft of the telescopic push rod 108 on the other side can be extended by a certain length to drive the corresponding crushing roller 107 to move directly below the feed hopper 104. At the same time, the crushing roller 107 can be rotated to facilitate the cleaning of the residual debris on the corresponding crushing roller 107 from the top. After that, the output shaft of the telescopic push rod 108 on the other side can be shortened by a certain length to move the cleaned crushing roller 107 away from the feed hopper 104. Then, the output shaft of the telescopic push rod 108 on one side can be extended by a certain length to move the crushing roller 107 to be cleaned directly below the feed hopper 104. Then, the other crushing roller 107 can be cleaned from the top.

[0026] Then, by driving the two crushing rollers 107 to reset via the telescopic push rods 108 on both sides, the waste tires can continue to be crushed.

[0027] like Figure 2As shown, two mounting brackets 105 are each equipped with a drive motor 109. The fixed end of the drive motor is connected to the inner wall of the mounting bracket 105. The output shaft of the drive motor 109 passes through the mounting bracket 105. A drive gear 110 is mounted on the output shaft of the drive motor 109, and a driven gear 111 meshing with the drive gear 110 is mounted on the mounting shaft 106. By simply starting the drive motor 109, the crushing roller 107 can be driven to rotate through the transmission engagement between the drive gear 110 and the driven gear 111.

[0028] like Figure 2 As shown, connecting grooves 201 are respectively provided on the front and rear side walls of the crushing box 103. Connecting sliders 202 that slide in contact with the connecting grooves 201 are respectively provided on the two mounting brackets 105. The sliding holes of the connecting grooves 201 and the cross-sections of the connecting sliders 202 are both T-shaped. After being pushed and pulled by the telescopic push rod 108, the mounting bracket 105 can slide left and right relative to the crushing box 103 under the sliding contact of the connecting grooves 201.

[0029] According to another embodiment of the present invention, such as Figure 3 As shown, guide slots 203 are respectively provided on the left and right side walls of the crushing box 103. A guide plate 204 is provided on the mounting frame 105 to insert into the guide slots 203. A locking bolt 205 is also screwed onto the guide slot 203, which abuts against the outer side wall of the guide plate 204 to fix the connection between the guide slot 203 and the guide plate 204. During the sliding operation of the mounting frame 105 by extending or shortening the output shaft of the telescopic push rod 108, the insertion and engagement of the guide plate 204 with the guide slot 203 provides better stability to the mounting frame 105. Furthermore, without the need for sliding adjustment, the locking bolt 205 passes through the side wall of the guide slot 203 and abuts against the guide plate 204, fixing the connection between the guide slot 203 and the guide plate 204. This prevents the mounting frame 105 from sliding independently and avoids damage to the telescopic push rod 108 due to the independent pushing and pulling action of the mounting frame 105.

[0030] According to another embodiment of the present invention, such as Figure 4As shown, a cone-shaped collection box 301 is fitted onto the lower end of the crushing box 103. A first extension plate 302 is also provided on the side of the crushing box 103, and a second extension plate 303 is also provided on the side of the collection box 301. A connecting spring 304 is provided between the first extension plate 302 and the second extension plate 303. A vibration motor 305 is also provided on the second extension plate 303. The crushed tire fragments can first fall into the cone-shaped collection box 301 for collection, and then be discharged, which facilitates subsequent processing and transportation by the user. At the same time, the vibration motor 305 can be started, which drives the collection box 301 to vibrate with the help of the spring, preventing the fragments from clogging and improving the discharge efficiency.

[0031] According to another embodiment of the present invention, such as Figure 4 As shown, the second extension plate 303 is also provided with a connecting slot 306, and the first extension plate 302 is also provided with a connecting plate 307 that plugs into the connecting slot 306. Through the plugging and engagement of the connecting groove 201 and the connecting plate 307, the collection box 301 can maintain vertical vibration, avoiding lateral displacement that would cause the crushing box 103 to collide and be damaged with the collection box 301, and preventing the spring from being easily damaged by deformation.

[0032] According to another embodiment of the present invention, such as Figure 4 As shown, a fastening plate 112 is also provided on the base 101, and the fastening plate 112 is also provided with fastening holes 113 for installing anchor bolts. The anchor bolts can pass through the fastening holes 113 and thus through the fastening plate 112 and connect to the ground, thereby stably fixing the device to the ground.

[0033] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
