Description

Technical Field

[0001] The utility model relates to the technical field of waste tire recycling, in particular to a waste tire crusher. Background Art

[0002] The current waste tire crusher is equipped with two sawtooth rollers in the frame, and the saw teeth on the two sawtooth rollers are arranged in an interlaced manner; the waste tire is fed into the frame through the feed port at the upper end of the frame, and the waste tire falls between the two sawtooth rollers and is driven by the saw teeth to pass between the two sawtooth rollers. The saw teeth squeeze and tear the passing waste tire, thereby crushing the waste tire. However, the waste tire is a material with a certain elasticity. When passing between the two sawtooth rollers, part of the waste tire tissue will not be pierced and crushed by the saw teeth, but will be squeezed and passed between the saw teeth, resulting in poor crushing effect of the waste tire. Summary of the invention

[0003] In order to improve the crushing effect of waste tires, the utility model provides a waste tire crusher.

[0004] The utility model adopts a technical solution as follows: a waste tire shredder comprises a frame, a feed port is arranged at the upper end of the frame, conveyor belts are arranged on the top walls of the frame located on both sides of the feed port, one end of the conveyor belts is aligned with the side wall of the feed port, two sawtooth rollers 1 are arranged in the frame, the two sawtooth rollers are located below the feed port and can rotate towards each other, a sawtooth roller 2 is also arranged in the frame, the number of the sawtooth rollers 2 is set to an integral multiple of two, the sawtooth roller 2 is located below the sawtooth roller 1, and the sawtooth size and sawtooth spacing on the sawtooth roller 2 are respectively greater than The teeth size and the spacing between teeth of the sawtooth roller one are small; the waste tire is driven by the conveyor belt into the feed port, and then falls between the two sawtooth rollers one and passes through the middle of the two sawtooth rollers one for the first step of crushing. The crushed waste tire becomes several rubber blocks, which further fall onto the sawtooth roller two and pass between the two sawtooth rollers two rotating in opposite directions. The sawtooth roller two further crushes the rubber blocks to become rubber particles. The waste tire is crushed twice in the frame, and the sawtooth of the sawtooth roller two is more dense, thereby improving the crushing effect of the waste tire.

[0005] Furthermore, the number of the sawtooth rollers 2 is four, and the four sawtooth rollers 2 are evenly divided into two groups, and the two groups of sawtooth rollers 2 are respectively located on both sides of the positions below the two sawtooth rollers 1, and a material dividing plate for guiding the two groups of sawtooth rollers 2 is also provided below the sawtooth rollers 1. When the rubber block falls onto the sawtooth rollers 2, only the two sawtooth rollers 2 rotating in opposite directions from top to bottom can achieve crushing, and the two sawtooth rollers 2 rotating away from top to bottom cannot achieve crushing of the waste tire. The setting of the material dividing plate can guide the rubber block into between the two sawtooth rollers 2 rotating in opposite directions, prevent the rubber block from falling between the two sawtooth rollers 2 rotating away from each other, and improve the crushing efficiency of the tire.

[0006] Furthermore, two screening plates are connected to the frame, the two screening plates are located on the inner walls on both sides of the frame, and the two screening plates are respectively located on one side of the two groups of sawtooth rollers 2; screening openings are provided on the side walls on both sides of the frame, and the two screening plates are respectively aligned with the lower ends of the corresponding screening openings; the outer walls on both sides of the frame are provided with collection boxes, and the two collection boxes are respectively located at the lower ends of the corresponding screening openings. When the rubber block passing through the sawtooth roller 1 falls onto the sawtooth roller 2, it will be driven to splash to both sides of the frame under the rotation of the sawtooth roller 2, and the splashed rubber block will fall onto the screening plate, slide out of the screening opening, and fall into the collection box. The operator can put the rubber block in the collection box on the conveyor belt and re-enter the chassis for crushing, so as to avoid the rubber block not being crushed by the sawtooth roller 2, thereby further improving the crushing effect of the waste tires.

[0007] Furthermore, the frame is connected to two guide plates near the feed inlet, the two guide plates are V-shaped, and the lower ends of the guide plates are located above the middle position of the two sawtooth rollers. The guide plates allow the waste tires to fall stably between the two sawtooth rollers, preventing the waste tires from falling onto the screening port and blocking the screening port.

[0008] Furthermore, two discharge ports are provided at the lower ends of the side walls on both sides of the frame, a discharge platform is provided on the inner bottom wall of the frame, and the top wall of the discharge platform is provided with two inclined walls, which are inclined toward the two discharge ports respectively. The rubber particles obtained by crushing by the second sawtooth roller will fall onto the inclined wall of the discharge platform, and roll or slide along the inclined wall to be discharged from the discharge port.

[0009] Furthermore, a mounting groove is provided on the inclined wall, a discharge plate is inserted into the mounting groove, a spring is connected between the discharge plate and the bottom wall of the mounting groove, and the side of the discharge plate facing away from the spring is flush with the corresponding inclined wall surface. When the rubber particles fall onto the discharge platform, they will impact the discharge plate, causing the discharge plate to compress the spring, and the spring will then recover and push the discharge plate, causing the rubber particles on the discharge plate to move toward the discharge port, facilitating the rapid discharge of the rubber particles and preventing the rubber particles from accumulating on the discharge platform.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. Through the setting of sawtooth roller 2, the rubber block passing through sawtooth roller 1 further falls onto sawtooth roller 2 and passes between the two sawtooth rollers rotating in opposite directions. Sawtooth roller 2 further crushes the rubber block to become rubber particles. The waste tire is crushed twice in the frame, and the saw teeth of sawtooth roller 2 are more dense, thereby improving the crushing effect of the waste tire.

[0012] 2. Through the setting of the screening plate and the opening of the screening port, the rubber blocks that are not crushed by the sawtooth roller 2 but are driven to splash will fall onto the screening plate, slide out of the screening port, and fall into the collection box. The operator can put the rubber blocks in the collection box on the conveyor belt and re-enter the chassis for crushing, avoiding the rubber blocks not being crushed by the sawtooth roller 2, thereby further improving the crushing effect of the waste tires.

[0013] 3. Through the cooperation of the discharge plate and the spring, the rubber particles falling on the discharge table can be pushed, so that the rubber particles on the discharge plate move toward the discharge port, which facilitates the rapid discharge of the rubber particles and avoids the accumulation of rubber particles on the discharge table.
