It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0017] In order to illustrate the technical solutions described in the present utility model, the following is illustrated through specific embodiments.

[0018] For ease of description, only parts related to the embodiments of the present utility model are shown.

[0019] Combined with Figures 1-3As shown, the waste tire feeding device includes an intermediate frame 1. Belt conveyor platforms 2 are rotatably arranged at the front and rear of the intermediate frame 1. A transition wheel 3 is rotatably arranged on the intermediate frame 1 between the two belt conveyor platforms 2. An adjusting mechanism for adjusting the rotation of the belt conveyor platform 2 is arranged on the intermediate frame 1. The adjusting mechanism includes an adjusting frame 4.

A lead screw 6 is rotatably arranged at the bottom of the frame 5. A lead screw sleeve 7 is sleeved on the lead screw 6. The bottom of the lead screw sleeve 7 is rotatably connected to the adjusting frame 4. A rotating motor 8 for driving the rotation of the lead screw 6 is also arranged on the frame 5. A driving mechanism for driving the rotation of the belt conveyor platform 2 is also arranged on the intermediate frame 1.

[0020] In recent years, with the rapid development of China's automobile industry, the tire industry has also entered a period of rapid growth. China has become a major tire producer and consumer in the world. Generally, waste tires will be pyrolyzed to realize the recycling and reuse of waste tires.

[0021] In this embodiment, a feeding mechanism is arranged at the front end of the waste tire feeding device, and a pyrolysis furnace is arranged at the rear end. When pyrolyzing waste tires, first, the waste tires are fed one by one onto the waste tire feeding device by the feeding mechanism. Under its feeding, the waste tires are fed into the pyrolysis furnace for pyrolysis treatment after passing through the pyrolysis station.

[0022] The waste tire feeding device is mainly composed of two belt conveyor platforms at the front and rear. When feeding, the feeding mechanism feeds the waste tires one by one and orderly onto the front belt conveyor platform. The waste tires pass through the front belt conveyor platform and are then transported to the rear belt conveyor platform, and finally are fed to the pyrolysis station to wait for pyrolysis.

[0023] In actual situations, the front and rear ends of the waste tire feeding device can be adjusted up and down according to the actual working conditions of its front and rear stations respectively, so as to adapt to the specific heights of the front and rear two stations.

[0024] In this structure, a pair of sliding plates 9 are arranged on the frame 5. A pair of supporting wheels 10 are arranged on the adjusting frame 4, and the sliding plate 9 is limited in the wheel groove of the supporting wheel 10 on the same side.

[0025] For example, when it is necessary to adjust the height of the front belt conveyor table, at this time, the corresponding rotating motor drives the lead screw to rotate, and the lead screw sleeve moves along the length direction of the lead screw. For example, when the front end of the front belt conveyor table needs to be adjusted upward, at this time, the lead screw sleeve moves upward along the length direction of the lead screw. During the movement of the lead screw sleeve, it drives the front adjusting frame to rotate upward. During this process, the supporting wheels slide upward along the slide plate. Under the pushing of the adjusting frame, the front belt conveyor table rotates upward. When it is necessary to adjust the height of the rear belt conveyor table, the corresponding rotating motor rotates simultaneously, and the rear adjusting frame rotates vertically. Driven by the rear adjusting frame, the rear belt conveyor table rotates vertically.

[0026] In addition, as Figure 2 , support components are respectively provided at the front and rear ends of the waste tire feeding device to prevent the corresponding belt conveyor table from directly contacting the ground. The support component includes a connecting sleeve 11. Rotating sleeves 12 are rotatably provided at both ends of the connecting sleeve 11. A screw rod 13 is inserted into the rotating sleeve 12. A chassis 14 is provided at the bottom of the screw rod 13. A limit handle 15 is screwed onto the connecting sleeve 11. The end of the limit handle 15 abuts against the rotating sleeve 12.

[0027] When the corresponding belt conveyor table needs to be adjusted downward and is only a short distance from the ground, before that, the limit handle can be loosened, and then the rotating sleeve can be rotated so that the chassis is vertically and downwardly arranged. After that, the limit handle is tightened. Finally, the belt conveyor table can be slowly adjusted downward until the chassis contacts the ground.

[0028] As a preferred structure, as Figure 1 , a pair of fixed cylinders 16 are provided on the bottom frame of the intermediate frame 1. A T-shaped support frame 17 is inserted into the fixed sleeve, and the two support frames 17 are arranged in opposite directions. A pair of support screw rods 18 are screwed downward at the ends of the support frame 17. A support plate 19 is provided at the bottom of the support screw rod 18. A number of adjustment holes 20 are provided on the support frame 17. The fixed cylinder 16 is inserted with a pin 21, and the pin 21 passes through the corresponding adjustment hole 20.

[0029] This device can be moved according to requirements. Brake wheels 31 are provided at the bottom of the intermediate frame 1. When it is necessary to move this device, first, according to the actual state of this device, adjust the corresponding belt conveyor table to ensure that the two belt conveyor tables are far from the ground. Then, loosen all the brake wheels, and the device can be pushed.

[0030] A circular hole is formed in the fixed cylinder, and a handle is provided at its front end. After pushing the device to the designated position, first lock the brake wheel, and then pull the two support frames outward. After the support frames are pulled in place, at this time, the circular hole corresponds to one of the adjustment holes up and down. Then, use a pin to insert into the circular hole and the adjustment hole in sequence, and the support frame is fixed. Finally, turn the support screws one by one until all the support plates support on the ground.

[0031] Further, as a preferred structure, such as Figure 3 , where at both ends of two adjacent belt pulleys 22 of the two belt conveyor tables 2, they respectively pass through the corresponding frames 5 and are provided with driven gears 23. The driving mechanism is a bidirectional driving motor 24 installed in the intermediate frame 1. On both driving shafts of the bidirectional driving motor 24, there are driving gears 25. A chain 26 is provided between the driving gears 25 and the driven gears 23 on the same side.

[0032] In this structure, when feeding waste tires, first, the bidirectional driving motor drives the driving gears on both sides to rotate. Under the linkage of the chain, the corresponding belt pulleys in the two belt conveyor tables rotate, so the belts in the belt conveyor tables rotate to realize the feeding of waste tires. In this structure, only one bidirectional driving motor is used to drive the two belt conveyor tables, which can simplify the structure of the device.

[0033] In this device, a pair of sliding frames 27 are further provided in the intermediate frame 1. A slider 28 is slidably arranged in the sliding frame 27. A pre-tightening gear 29 is rotatably arranged on the slider 28. The pre-tightening gear 29 abuts against the chain 26 on the same side. An adjusting screw 30 is inserted into the sliding frame 27, and the adjusting screw passes through the slider.

[0034] In this structure, a threaded groove is formed in the slider, and the adjusting screw is located in the threaded groove. The pre-tightening gear can be used to adjust the tightness of the corresponding chain. When adjusting the tightness of the chain, only need to rotate the adjusting screw. During the rotation of the adjusting screw, the slider slides along the height direction of the adjusting screw, so that the pre-tightening gear is adjusted vertically. If the pre-tightening gear moves upward a small distance, the chain becomes slightly loose.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
