Description

Technical Field

[0001] This invention relates to the field of pipe recycling technology, and in particular to a waste pipe recycling device and its usage method. Background Technology

[0002] Waste pipes refer to pipes that have been damaged to varying degrees due to use, such as breakage or aging, and are no longer usable. In order to improve the utilization rate of resources, these waste pipes are recycled. For the recycling of waste plastic pipes, they are generally first crushed by a crushing device to turn the large waste pipes into fragments for subsequent processing.

[0003] In the existing technology, when the crushing device used for pipe crushing and dismantling is reused, its feed port is generally set at the top or side of the device. When the feed port is located at the top of the device, the waste pipe needs to be unloaded from a height, which is difficult and strenuous and inconvenient for unloading. When the feed port is located on the side wall of the device, although it is convenient to feed directly, the feed port is directly exposed at a horizontal position, which increases the safety hazard and the risk factor of the unloading operation.

[0004] To address the aforementioned issues, a waste pipe recycling device and its usage method are proposed. Summary of the Invention

[0010] Preferably, a lifting screw is rotatably connected to the side of the limiting baffle away from the V-shaped slot. One end of the lifting screw passes through the outer wall of the feeding hood and extends to the outside. A nut seat is threadedly connected to the outer wall of the lifting screw, and the outer wall of the nut seat is fixedly connected to the outer wall of the feeding hood.

[0011] Preferably, vertical through holes are provided on both sides of the feeding hood at positions corresponding to the limiting baffle. A connecting slider is fixedly connected to one end of the limiting baffle facing the vertical through hole. The end of the connecting slider passes through the vertical through hole and is movably connected to a guide rod. Both ends of the guide rod are fixedly connected to the outer wall of the feeding hood.

[0012] Preferably, the feeding hood has an arc-shaped groove on one side facing the outer wall of the crusher shell, the arc-shaped groove matching the arc shape of the outer wall of the crusher shell, a roller groove is formed on the inner wall of the arc-shaped groove, an auxiliary roller is rotatably connected in the roller groove, and the outer wall of the auxiliary roller is fitted to the outer wall of the crusher shell.

[0013] Preferably, one end of the connecting shaft passes through the inner wall of the crusher casing and is fixedly connected to a drive disc. A drive rod is rotatably connected to the side of the drive disc away from the connecting shaft. A rotating connecting seat is rotatably connected to the end of the drive rod away from the drive disc. The outer wall of the rotating connecting seat is fixedly connected to the side wall of the discharge push plate.

[0014] Preferably, a straight groove is provided at the bottom of the inner wall of the crusher shell, and a limiting slide rod is fixedly connected to the side wall of the discharge push plate at the corresponding position of the straight groove. The end of the limiting slide rod away from the discharge push plate is movably inserted into the straight groove.

[0015] Preferably, the crusher shell has a discharge chamber connected to the crushing chamber on the side away from the feed hood, the bottom of the discharge chamber is provided with a discharge ramp, and a discharge hood is fixedly connected to the inside of the crusher shell at the bottom of the feed inlet, the inside of the discharge hood is wider at the top and narrower at the bottom.

[0016] The present invention also provides a method for using a waste pipe recycling device, comprising the following steps:

[0017] Step 1: In the initial state, the feeding hood is located on the horizontal side of the crusher shell, and the discharge pusher plate is located inside the crusher shell near the discharge chamber. One end of the waste pipe to be crushed is inserted into the feeding hood. The hydraulic telescopic rod extends, driving the connecting plate and connecting shaft to rotate, driving the feeding hood to move along the arc-shaped outer wall of the crusher shell, and driving the waste pipe to move upward and change direction. When the feeding hood moves to the feed inlet position, the waste pipe is in a downward state and is discharged from the feed inlet into the crushing device inside the crusher shell for crushing. After the waste pipe has completely entered the crusher shell from the feeding hood, the hydraulic telescopic rod retracts, driving the connecting plate to rotate in the opposite direction, so that the feeding hood moves back to its original position, realizing intermittent feeding of waste pipe.

[0018] Step two: As the hydraulic telescopic rod extends, it drives the connecting shaft to rotate. Simultaneously, the connecting shaft drives the drive disc to rotate, and the rotation of the drive disc pushes the drive rod to move. Utilizing the limiting and guiding effect of the linear chute and the limiting slide rod on the discharge push plate in the horizontal straight direction, the drive rod drives the discharge push plate to move horizontally through the rotating connecting seat. This pushes the fragments that have fallen to the bottom of the crusher casing after a single crushing by the crushing device to the discharge ramp position in the discharge chamber. The slope of the discharge ramp causes the fragments to roll out and be discharged. Furthermore, the discharge push plate moves back in the opposite direction as the connecting shaft rotates in the opposite direction, achieving intermittent discharge of waste pipe fragments from the crusher casing.

[0019] The technical effects and advantages of this invention are as follows:

[0020] (1) The present invention can conveniently feed waste pipes into the feeding hood when the feeding hood is in a horizontal position, realize low-level horizontal feeding, and make feeding more flexible and convenient. At the same time, the feeding hood moves along the arc-shaped outer wall of the crusher shell to change the waste pipes from a horizontal state to a vertical state and drop them from the feed inlet to realize automatic feeding, which is conducive to improving the convenience and work efficiency of waste pipe feeding.

[0021] (2) The present invention can drive the discharge pusher plate to move back and forth while the feeding hood is intermittently feeding, so as to realize intermittent discharge from the crusher shell, avoid the accumulation of fragments, improve the convenience of discharge, and save the tedious manual cleaning, thereby improving the work efficiency of waste pipe crushing and processing.

[0022] (3) By setting an adjustable limiting baffle inside the feeding hood, and with the V-shaped groove on the outer wall of the limiting baffle, the present invention can limit the waste pipe inserted between the feeding hood and the limiting baffle, so as to prevent the waste pipe from falling off during the movement of the feeding hood, making the feeding of waste pipe more stable and safer.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] This invention provides, for example Figure 1-5The illustrated waste pipe recycling device and its usage method include a crusher housing 1 and a crushing device 12. The crushing device 12 is disposed within a crushing chamber inside the crusher housing 1. The crushing device 12 can be any existing crushing device, such as two horizontally arranged crushing rollers driven by a crushing motor and utilizing the synchronous transmission of gears between the two crushing pipe shafts to make the two crushing rollers rotate synchronously in opposite directions, thus crushing the waste pipe. A reciprocating discharge pusher 3 is provided at the bottom of the crushing chamber for intermittently cleaning the fragments within the crushing chamber. The reciprocating movement of the discharge pusher 3 at the bottom of the crushing chamber pushes out the waste pipe fragments that fall after being crushed by the crushing device 12, preventing the fragments from accumulating below the crushing device 12 and affecting the subsequent crushing of waste pipe. The crusher shell 1 has a feed inlet 11 at the top for feeding the crushed material. One side of the crusher shell 1 is arc-shaped. The arc shape of the outer wall of the crusher shell 1 allows the feeding hood 2 to move along its outer wall and rotate. This allows the feeding hood 2 to rotate smoothly and move along the outer wall of the crusher shell 1, increasing its stability. The outer wall of the crusher shell 1 is equipped with a feeding hood 2 that can move along its arc-shaped outer wall. By rotating the feeding hood 2 from a horizontal position to a vertical position, the waste pipe material at a lower position can be fed to a higher position for feeding. This not only avoids the danger of the feed inlet 11 being set horizontally on the crusher shell 1, but also allows the waste pipe material to be fed at a lower position, making the manual feeding operation more flexible and convenient, with lower labor intensity, less difficulty, and higher work efficiency.

[0031] Furthermore, an adjustable limiting baffle 24 is provided at the inner cavity port of the feeding hood 2 to limit the position of the waste pipe inside the feeding hood 2. Multiple V-shaped slots 241 are spaced parallel to each other at the bottom end of the limiting baffle 24. These V-shaped slots 241, in conjunction with the horizontal inner wall of the feeding hood 2, achieve three-point clamping of the waste pipe, ensuring stability after the end of the waste pipe enters the feeding hood 2 and preventing slippage during upward movement. The side of the limiting baffle 24 opposite to the V-shaped slots 241 rotates... A lifting screw 242 is connected, one end of which penetrates the outer wall of the feeding hood 2 and extends to the outside. A nut seat 243 is threadedly connected to the outer wall of the lifting screw 242. The outer wall of the nut seat 243 is fixedly connected to the outer wall of the feeding hood 2. With the setting of the lifting screw 242 and the nut seat 243, the lifting screw 242 can rotate clockwise or counterclockwise in the nut seat 243 to drive the limit baffle 24 to move up and down, so as to adjust the position and adapt to the limit of multiple sizes of waste pipes, making it more flexible to use.

[0032] Meanwhile, vertical through holes 244 are provided on both sides of the feeding hood 2 at positions corresponding to the limiting baffle 24. A connecting slider 246 is fixedly connected to one end of the limiting baffle 24 directly opposite the vertical through hole 244. The end of the connecting slider 246 passes through the vertical through hole 244 and is movably connected to a guide rod 245. Both ends of the guide rod 245 are fixedly connected to the outer wall of the feeding hood 2. When the limiting baffle 24 moves, it drives the connecting slider 246 to move on the outer wall of the guide rod 245, thereby guiding the movement direction of the limiting baffle 24 and maintaining the accuracy and stability of the position adjustment of the limiting baffle 24.

[0033] In a preferred embodiment, a connecting shaft 22 is rotatably connected to the shaft center of the crusher housing 1, and a connecting plate 21 is fixedly connected to the end of the connecting shaft 22. The end of the connecting plate 21 away from the connecting shaft 22 is fixedly connected to the side wall of the feeding hood 2. A hydraulic telescopic rod 23 is movably connected between the connecting plate 21 and the outer wall of the crusher housing 1. The hydraulic telescopic rod 23 cooperates with an external hydraulic cylinder to supply oil, driving the extension and retraction of the hydraulic telescopic rod 23, so that the hydraulic telescopic rod 23 can drive the connecting plate 21 and the connecting shaft 22 to rotate. In this way, the movement of the feeding hood 2 can be achieved, and it can also be used as a driving source for the movement of the discharge push plate 3, which has higher practical value.

[0034] Furthermore, the feeding hood 2 has an arc-shaped groove on one side facing the outer wall of the crusher shell 1. The arc-shaped groove matches the arc shape of the outer wall of the crusher shell 1. A roller groove 25 is provided on the inner wall of the arc-shaped groove. An auxiliary roller 26 is rotatably connected in the roller groove 25. The outer wall of the auxiliary roller 26 is fitted to the outer wall of the crusher shell 1. When the feeding hood 2 moves on the outer wall of the crusher shell 1, the auxiliary roller 26 rotates, which reduces the frictional resistance between the feeding hood 2 and the crusher shell 1 and makes the movement of the feeding hood 2 more stable.

[0035] In addition, one end of the connecting shaft 22 passes through the inner wall of the crusher shell 1 and is fixedly connected to the drive disc 33. The drive disc 33 is rotatably connected to the side away from the connecting shaft 22, and the end of the drive disc 34 away from the drive disc 33 is rotatably connected to the rotating connecting seat 35. The outer wall of the rotating connecting seat 35 is fixedly connected to the side wall of the discharge push plate 3. When the connecting shaft 22 rotates, it can drive the drive disc 33 to rotate, so that the drive disc 33 drives the drive rod 34 to move. In this way, the drive rod 34 can drive the discharge push plate 3 to move, realizing the conversion of the extension and retraction action of the hydraulic telescopic rod 23 into the driving force for the translation of the discharge push plate 3, making the device more efficient and energy-saving.

[0036] The bottom of the inner wall of the crusher casing 1 is provided with a straight slide groove 31. The side wall of the discharge push plate 3 is fixedly connected to the corresponding position of the straight slide groove 31 with a limiting slide rod 32. The end of the limiting slide rod 32 away from the discharge push plate 3 is movably inserted into the straight slide groove 31. By moving the limiting slide rod 32 in the straight slide groove 31, the translation of the discharge push plate 3 is guided, making its movement process more stable.

[0037] Furthermore, a discharge chamber 14 connected to the crushing chamber is provided on the side of the crusher shell 1 away from the feeding hood 2. A discharge ramp 15 is provided at the bottom of the discharge chamber 14. The setting of the discharge ramp 15 can be coordinated with the pushing limit position of the discharge push plate 3 to discharge the pushed waste pipe fragments out of the crusher shell 1, which is conducive to the discharge. A discharge hood 13 is fixedly connected to the inner side of the crusher shell 1 and located at the bottom of the feed inlet 11. The inner side of the discharge hood 13 is wider at the top and narrower at the bottom, which plays a guiding role for the waste pipe falling from the feeding hood 2, so that the waste pipe can fall from the middle position of the crushing device 12 for crushing.

[0038] The usage method includes the following steps:

[0039] Step 1: In the initial state, the feeding hood 2 is located on the horizontal side of the crusher shell 1, and the discharge push plate 3 is located inside the crusher shell 1 near the discharge chamber 14. One end of the waste pipe to be crushed is inserted into the feeding hood 2. The hydraulic telescopic rod 23 extends, driving the connecting plate 21 and the connecting shaft 22 to rotate, driving the feeding hood 2 to move along the arc-shaped outer wall of the crusher shell 1, and driving the waste pipe to move upward and change direction. When the feeding hood 2 moves to the position of the feed inlet 11, the waste pipe is in a downward state and is discharged from the feed inlet 11 into the crushing device 12 inside the crusher shell 1 for crushing. After the waste pipe has completely entered the crusher shell 1 from the feeding hood 2, the hydraulic telescopic rod 23 retracts, driving the connecting plate 21 to rotate in the opposite direction, so that the feeding hood 2 moves back to its original position, realizing intermittent feeding of waste pipe.

[0040] Step two: As the hydraulic telescopic rod 23 extends, it drives the connecting shaft 22 to rotate. Simultaneously, the connecting shaft 22 drives the drive disc 33 to rotate. The rotation of the drive disc 33 pushes the drive rod 34 to move. The linear slide 31 and the limiting slide rod 32 limit and guide the discharge push plate 3 in the horizontal straight direction, causing the drive rod 34 to drive the discharge push plate 3 to move horizontally through the rotating connecting seat 35. This pushes the fragments that have fallen to the bottom of the inner side of the crusher shell 1 after being crushed once by the crushing device 12 to the discharge ramp 15 of the discharge chamber 14. The slope of the discharge ramp 15 causes the fragments to roll out and be discharged. The discharge push plate 3 moves back in the opposite direction as the connecting shaft 22 rotates in the opposite direction, realizing the intermittent discharge of waste pipe fragments from the crusher shell 1.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
