Description

Technical Field

[0001] The utility model relates to the technical field of scrapped car dismantling, in particular to a waste tire dismantling device. Background Art

[0002] With the rapid development of the economy, the number of cars on the road continues to grow rapidly worldwide. At the same time, a large number of cars are scrapped every year due to reaching the end of their service life, serious accidents or technical failures. Cars are complex products made of a variety of materials, including a large number of valuable materials (such as steel, aluminum, copper, etc.) and recyclable parts. Among them, discarded tires are one of the recyclable parts. After mechanically crushing, discarded tires are used to support rubber runways and rubber floor tiles. They can also be laid on roads to improve the fatigue resistance, skid resistance and wear resistance of asphalt pavements, which can effectively extend the service life of roads. However, after removing the wheels of scrapped cars, the tires and wheels need to be separated before they can be crushed. There are also various equipment for separating tires and wheels on the current market. For example, Chinese patent publication CN219927385U discloses a tire-wheel rapid separation machine, which includes an actuator arm, a pressing arm, and a power system. The power system is connected to the actuator arm and the pressing arm, which are fixed obliquely to the surface of an operating table. The power system is mounted on the operating table, and a lifting assembly is provided on the side of the operating table away from the actuator arm and the pressing arm. The operating table surface is provided with a discharge port, and the discharge port is equipped with a gear grading assembly. In this way, the tire and wheel can be effectively separated.

[0003] However, existing tire and wheel separation equipment has the following deficiencies in actual use: First, during the separation process, the lifting assembly and the pressing arm must first complete the fixing action before the actuator arm can perform the separation action. This cumbersome action makes the existing tire and wheel separation equipment inefficient. Second, because the tire must be moved to the operating table before operation, the existing tire and wheel separation equipment requires an operator to carry out the loading and unloading of the separated tire after each tire and wheel separation. After long-term use, the operator is prone to fatigue. In view of this, the waste tire disassembly device of the present application is proposed. Utility Model Content

[0033] like Figure 1As shown, in one embodiment, a waste tire disassembly device 1 includes a chassis 10 and a separation assembly 20. The chassis 10 is provided with a feeding hole 11. The separation assembly 20 includes a push arm 21, a cross bar 22, a triangular block 23, an adjustment member 24 and two support rods 25. The push arm 21 is provided on the chassis 10, and the cross bar 22 is detachably provided on the chassis 10. The push arm 21 and the cross bar 22 are respectively located on both sides of the feeding hole 11. The triangular block 23 is provided on the chassis 10, and the triangular block 23 is located at the feeding hole 11 near the cross bar. On the inner wall of 22, the adjusting part 24 is set on the chassis 10, one end of the two support rods 25 are rotatably set on the chassis 10, the other ends of the two support rods 25 are connected to the adjusting part 24, and the two support rods 25 are both located in the loading hole 11, the two support rods 25 are used to jointly support the wheel, the adjusting part 24 is used to adjust the angle between the two support rods 25 so that the height of the wheel can be adjusted, and the pushing arm 21 pushes the wheel hub laterally so that the wheel is tilted against the triangular block 23, thereby causing the pushing arm 21 to separate the wheel hub from the tire.

[0034] It should be noted that the chassis 10 is provided with two uprights 12, and the two uprights 12 are spaced apart and located on one side of the feeding hole 11, so that one side of the feeding hole 11 forms a discharge channel, and the two uprights 12 tend to form a right triangle structure. Furthermore, the separation component 20 also includes a top plate, which is provided on the chassis 10, and is located on the side of the feeding hole 11 away from the two uprights 12. The two uprights 12, the top plate and the feeding hole 11 together form an operating chamber. Furthermore, the ejection arm 21 is a hydraulic rod structure, which is provided on the top plate, and the output end of the ejection arm 21 faces the two uprights 12, so that the output end of the ejection arm 21 is located in the operating chamber. Furthermore, the triangular block 23 is provided on the chassis 10, and the triangular block 23 is located on the inner side wall of the feeding hole 11 near one end of the two uprights 12, and the angle of the triangular block 23 faces the ejection arm 21. Furthermore, an adjustment member 24 is mounted on the chassis 10 and is located on the side of the feeding hole 11 away from the triangular block 23. One end of each of the two support rods 25 is pivotally connected to the chassis 10 and located on an inner sidewall of the feeding hole 11 near the two uprights 12. The triangular block 23 is positioned between the two support rods 25. The other ends of the two support rods 25 span the feeding hole 11 and are connected to the adjustment member 24 on the side facing the feeding hole 11. When the tire is positioned in the feeding hole 11, the two support rods 25 can jointly support the wheel, allowing the wheel to be placed in the feeding hole 11.Furthermore, since the triangular block 23 is located between the two support rods 25, when the wheel is placed on the two support rods 25, the triangular block 23 and the tire are in a horizontal position. In this way, when the pushing arm 21 pushes the wheel, the triangular block 23 can abut against the tire. Furthermore, since the triangular block 23 is arranged on the inner side wall of the feeding hole 11, and the angle position of the triangular block 23 extends toward the center of the feeding hole 11, the position of the triangular block 23 is more protruding relative to the position of the cross bar 22. In addition, the pushing arm 21 is located on the side of the feeding hole 11 away from the triangular block 23, and the output end of the pushing arm 21 is toward the triangular block 23, and the output end of the pushing arm 21 is higher than the triangular block 23, so that the pushing wall can push the wheel hub close to the tire position. In this way, when the pushing arm 21 pushes the wheel hub, the wheel slides laterally along the two support rods 25 close to the triangular block 23. Since the position of the triangular block 23 is more protruding relative to the position of the cross bar 22, the pushing arm 21 pushes the wheel to The tire first contacts the triangular block 23, and because the output end of the pushing arm 21 is higher than the triangular block 23, after the pushing arm 21 and the tire contact the triangular block 23, the upper half of the wheel will lean against the cross bar 22, so that an angle greater than a right angle is formed between the cross bar 22, the triangular block 23 and the pushing arm 21, and under the continuous pushing of the wheel hub by the pushing arm 21, the triangular block 23 will first squeeze the tire to discharge the gas inside the tire, and the triangular block 23 will push one side of the tire toward the other side of the tire. One side is brought close to expose the side of the wheel hub that is away from the ejection arm 21. At this time, the wheel hub will be perpendicular to the two vertical frames 12. Since the ejection arm 21 pushes the end of the wheel hub that is close to the triangular block 23, the end of the wheel hub that is away from the triangular block 23 abuts against the cross bar 22. Moreover, the cross bar 22 and the triangular block 23 are located on the same side of the wheel. The ejection arm 21 is located on that side of the wheel, so that the ejection arm 21 continues to push the wheel hub, so that the wheel hub is separated from the tire and slides out of the discharge channel between the two vertical frames 12. In this way, the wheel can quickly separate the tire and the wheel hub, thereby improving work efficiency.

[0035] like Figure 1 As shown, in one embodiment, an angled portion 211 is provided on the output end of the pushing arm 21 , and the angled portion 211 faces the triangular block 23 . The angled portion 211 is used to push the wheel close to the triangular block 23 .

[0036] It should be noted that the beveled portion 211 tends to be a right triangle structure, and one of the angles of the beveled portion 211 points downwardly toward the triangular block 23, so that when the beveled portion 211 abuts against the wheel hub, the beveled portion 211 can be closer to the edge of the wheel hub, so that when the beveled portion 211 pushes the wheel to abut against the triangular block 23, the two opposite forces between the wheel hub and the tire are greater, so that the wheel hub and the tire can be separated faster. Furthermore, the other angles of the beveled portion 211 are facing upwards, and when the beveled portion 211 pushes the wheel hub close to one end of the triangular block 23, the end of the wheel hub away from the triangular block 23 abuts against the cross bar 22. When the beveled portion 211 pushes one end of the wheel hub to separate from the tire, the beveled portion 211 will push the end of the wheel hub away from the cross bar 22 to enter the discharge channel. At this time, the end of the wheel hub close to the cross bar 22 still stays above the feeding hole 11. When the wheel hub is completely separated from the tire, the end of the wheel hub close to the cross bar 22 will fall downward into the feeding hole 11. Therefore, the other angle of the beveled portion 211 is facing upwards, so that after the wheel hub is separated from the tire, the wheel hub can fall on the beveled portion 211, thereby sliding along the inclined surface of the beveled portion 211 into the discharge channel, and then the wheel hub can be smoothly discharged from the discharge channel, so that the operator can collect and organize it.

[0037] like Figures 1 to 3 As shown, in one embodiment, the adjusting member 24 includes a screw 241 and two sliders 242. The screw 241 is rotatably set on the chassis 10. One end of the two sliders 242 is slidingly connected to the chassis 10, and the other end of the two sliders 242 is threadedly connected to the screw 241.

[0038] It should be noted that both ends of the screw rod 241 are inserted through the chassis 10, allowing the screw rod 241 to rotate relative to the chassis 10. Furthermore, a chute is provided on the chassis 10, the direction of the chute being the same as the direction of the screw rod 241 being inserted. One end of each of the two sliders 242 is engaged with the chute, allowing the two sliders 242 to slide relative to the chassis 10. Furthermore, the ends of the two sliders 242 away from the chute are threadedly engaged with the screw rod 241. Thus, when the screw rod 241 rotates, it causes the two sliders 242 to slide relative to the chassis 10.

[0039] like Figure 3 、 Figure 6 As shown, in one embodiment, two sliding blocks 242 are each provided with a through-hole 2421 , and one end of each of the two supporting rods 25 is plugged into the two through-holes 2421 .

[0040] It should be noted that the two sliders 242 have the same structure. A through-hole 2421 is provided on the slider 242. The through-hole 2421 is located between the slider 242 and the slide slot and the screw rod 241, and the through-hole 2421 passes through the two opposite ends of the slider 242. The through-hole 2421 is oriented toward the two uprights 12. Furthermore, a cylinder is provided in the through-hole 2421, and the cylinder connects the upper and lower inner walls of the through-hole 2421. Furthermore, the two support rods 25 have the same structure. One end of the support rod 25 is rotatably connected to the chassis 10, and the other end of the support rod 25 is a flat U-shaped structure, the thickness of which is less than the width of the through-hole 2421, so that one end of the U-shaped structure of the support rod 25 can be inserted into the through-hole 2421, and the U-shaped structure is plugged into the cylinder. In this way, when the slider 242 slides, it can drive one end of the support rod 25 to swing.

[0041] like Figure 5 As shown, in one embodiment, two threads 2411 are provided on the screw rod 241 , and the rotation directions of the two threads 2411 are opposite, and the two sliders 242 are screwed to the two threads 2411 respectively.

[0042] It should be noted that the screw 241 is provided with two threads 2411, and the rotation directions of the two threads 2411 are inconsistent. For example, one of the threads 2411 is a right-hand spiral and the other thread 2411 is a left-hand spiral, and the two threads 2411 each occupy half of the entire screw 241. The two sliders 242 are also provided with screw teeth on one end that is screwed to the screw 241, and the screw teeth on the two sliders 242 are respectively adapted to the two threads 2411, so that the two sliders 242 can be screwed to the two threads 2411 respectively. In this way, when the screw 241 is rotated to drive the two sliders 242 to slide, the two sliders 242 can slide in two opposite directions respectively. For example, when the screw 241 is rotated clockwise, the two sliders 242 slide against each other. When the screw rod 241 rotates counterclockwise, the two sliders 242 slide away from each other, so that the two support rods 25 and the two sliders 242 plug-in sides will also move closer to or away from each other. Furthermore, because the ends of the two support rods 25 close to the triangular block 23 are rotatably connected to the chassis 10, when the two support rods 25 and one end of the two sliders 242 plug-in blocks approach each other, the two support rods 25 form a triangular bracket relative to the feeding hole 11, and the angle between the two support rods 25 gradually decreases from one end of the triangular block 23 to the end of the adjustment member 24. In this way, the wheels located on the two support rods 25 will lean against the cross bar 22, and then when the pushing arm 21 pushes the wheel, the tire can abut against the triangular block 23 more tightly, thereby improving work efficiency. Moreover, when the angle between the two support rods 25 becomes smaller, the support points of the two support rods 25 supporting the tire are closer, making the height of the tire higher. In this way, when dealing with various wheels with different flatnesses on the market, the angle between the two support rods 25 can be adjusted to ensure that the tire is better in contact with the triangular block 23, allowing the wheel hub to be separated from the tire more quickly. Furthermore, for example, when the screw 241 rotates counterclockwise, the two sliders 242 drive the two support rods 25 to slide away from each other, increasing the distance between the two support rods 25, allowing the two support rods 25 to support wheels with larger frames, and also ensuring that the tire is better in contact with the triangular block 23.

[0043] like Figure 1 As shown, in one embodiment, the adjusting member 24 further includes a driving wheel 243, a belt 244 and a driven wheel 245. The driving wheel 243 is rotatably arranged on the chassis 10, the driven wheel 245 is arranged at one end of the screw 241, and the belt 244 is respectively sleeved on the driving wheel 243 and the driven wheel 245.

[0044] It should be noted that the adjusting member 24 also includes a handle, which is rotatably arranged in the circumferential direction of the driving wheel 243. When the handle drives the driving wheel 243 to rotate, the driven wheel 245 drives the screw 241 to rotate so that the two sliders 242 can slide closer to or away from each other, thereby adjusting the distance between the two support rods 25.

[0045] like Figures 1 to 2 As shown, in one embodiment, a plurality of slots 121 are further provided on the chassis 10, and each slot 121 is located on both sides of the cross bar 22, and each slot 121 on both sides of the cross bar 22 corresponds to each other one by one, and the two ends of the cross bar 22 are respectively connected to any two corresponding slots 121 to make the position of the cross bar 22 adjustable.

[0046] It should be noted that a plurality of slots 121 are formed on the two facing sides of the two uprights 12, and the slots 121 on the two uprights 12 correspond to each other and are aligned with each other. Each slot 121 is located on the end of the two uprights 12 away from the triangular block 23. It should be noted that each slot 121 extends obliquely downward from the side of the upright 12 facing the push arm 21 to the middle of the upright 12. When the two ends of the crossbar 22 are respectively engaged with any of the aligned slots 121 on the two uprights 12, the crossbar 22 cannot fall off on its own. In addition, the position of the crossbar 22 can be adjusted along the vertical direction of the two uprights 12, so that the crossbar 22 can abut against wheel hubs of different sizes.

[0047] like Figures 1 to 2 、 Figure 4 As shown, in one embodiment, two inclined blocks 13 are further provided on the chassis 10 . The two inclined blocks 13 are respectively located at two ends of the chassis 10 , and the two inclined blocks 13 are aligned with the two ends opposite to the feeding hole 11 .

[0048] It should be noted that the triangular block 23 and the pushing arm 21 are respectively located on opposite sides of the feeding hole 11, so that the pushing arm 21 can push the wheel close to the triangular block 23, and then the wheel hub can be pushed out from one side of the triangular block 23. The two inclined blocks 13 are respectively located on the other two opposite sides of the feeding hole 11, so that the operator can push the wheel and roll it into the feeding hole 11 from one of the inclined blocks 13. When the separation of the tire and the wheel hub is completed, the wheel hub is pushed out from one side of the triangular block 23, and the tire can be rolled out from one end of the other inclined block 13, so that the operator can easily send the wheel into the working chamber and can also easily roll the tire out of the working chamber. In this way, the operator can easily complete the loading and unloading work, reduce the operator's transition fatigue, and thus improve work efficiency.

[0049] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
