[0053] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0054] Example 1

[0055] like Figure 1 As shown, the pipe shredder includes:

[0056] Shredding room 1;

[0057] The discharge port 3, the shredding chamber 1 is connected to the discharge port 3;

[0058] Shredding assembly 1-7, shredding assembly 1-7 is arranged in shredding chamber 1;

[0059] Processing chamber 4, which is connected to shredding chamber 1, and is suitable for feeding the pipe into shredding chamber 1;

[0060] The extrusion assembly 5 is disposed in the processing chamber 4 and includes an electrically controlled cylinder 51 and an extrusion plate 55. The electrically controlled cylinder 51 is adapted to drive the extrusion plate 55 to move longitudinally in the processing chamber 4 to extrude the pipe;

[0061] The contraction assembly is suitable for connecting the electronically controlled cylinder 51 and the extrusion disc 55 .

[0062] like Figure 2 As shown, a limiting assembly 6 is provided on the processing chamber 4. The limiting assembly 6 is divided into two groups, which are respectively connected to both sides of the opening of the processing chamber 4. Each group of limiting assemblies 6 includes a limiting plate 62 and a placement plate 61. The limiting plate 62 is located above the placement plate 61.

[0063] like Figure 2 As shown, the retraction assembly includes a connecting plate 52, a telescopic rod 53 and a retraction spring 54;

[0064] The connecting disk 52 is connected to the bottom of the telescopic end of the electric control cylinder 51, the telescopic rod 53 is connected between the connecting disk 52 and the extrusion disk 55, the contraction spring 54 is sleeved on the outside of the telescopic rod 53, and the two ends of the contraction spring 54 are respectively connected to the bottom of the connecting disk 52 and the top of the extrusion disk 55.

[0065] like Figure 2 As shown, the shredding assembly 7 includes a motor 71 and a crushing tool 72. The motor 71 is located outside the shredding chamber 1, and the crushing tool 72 is located inside the shredding chamber 1.

[0066] The motor 1 71 is connected to the crushing tool 1 72 to drive the crushing tool 1 72 to rotate.

[0067] like Figure 2 As shown, a shredding chamber 2 2 communicating with the inner spaces of the shredding chamber 1 and the discharge port 3 is provided between the shredding chamber 1 and the discharge port 3;

[0068] A shredding assembly 2 9 is provided in the shredding chamber 2;

[0069] A screen 8 is provided on the outside of the shredding component 2 9 , and the screen 8 is located inside the shredding chamber 2 2 .

[0070] like Figure 2 As shown, the shredding assembly 2 9 includes a motor 2 91 and a crushing tool 2 92 . The motor 2 91 is located outside the shredding chamber 2 , and the crushing tool is located inside the shredding chamber 2 .

[0071] The second motor 91 is connected to the second crushing tool 92 to drive the second crushing tool 92 to rotate in the second shredding chamber 2;

[0072] The second crushing tool 92 is located inside the screen 8 .

[0073] The working principle of this embodiment is as follows:

[0074] When in use, first place the pipe to be shredded into the interior of the processing chamber 4 under the limit of the limit assembly 6, and then start the extrusion assembly 5 to extrude the pipe. The processing chamber 4 is rectangular, so the pipe needs to be placed vertically inside the processing chamber 4. After extrusion, the end face of the pipe rests on the crushing tool 1 72 in the shredding chamber 1, and after being crushed by the crushing tool 1 72, it enters the processing chamber 42, is crushed again by the crushing tool 2 92, and the crushed fragments are screened by the screen 8. The qualified fragments pass through the mesh on the screen 8 into the discharge port 3 and are discharged from the shredding chamber 2 2;

[0075] The limiting assembly 6 comprises a placement plate 61 for placing the pipe and a limiting plate 62 for limiting the left and right shaking of the pipe. This arrangement enables the pipe to enter the processing chamber 4 in a vertical and stable manner, facilitating the subsequent shredding process. The limiting assembly 6 can cooperate with an external automatic conveying device to achieve an automated effect.

[0076] The crushing tool 1 72 can be an auger, which can effectively send the pipe fragments into the interior of the processing chamber 42 after initially tearing the pipe, and then be shredded again by the crushing tool 2 92. It should be noted that the auger has a weak tearing ability, but it can also tear and transport commonly used plastic pipes and other pipes.

[0077] The fragments that have been initially shredded by the shredding tool 1 72 are transported to the interior of the shredding chamber 2 2, specifically to the interior of the screen 8, where they are further shredded by the rotating tool 2 until the fragments can pass through the sieve holes of the screen 8. The fragments that pass through the screen 8 are discharged from the discharge port 3, and the fragments that cannot pass through are shredded again by the rotating tool 2 until they are shredded to a size that can pass through the screen 8.

[0078] Example 2

[0079] like Figure 1 As shown, this embodiment further includes the following structures on the basis of the embodiment 1: a cleaning assembly 10 is provided inside the shredding chamber 2, and the cleaning assembly 10 includes a revolution assembly and a cleaning roller 1004;

[0080] The revolution assembly is suitable for driving the cleaning roller 1004 to rotate with the axis of the screen 8 as the center;

[0081] A brush is provided on the outer peripheral surface of the cleaning roller 1004 and contacts the screen 8 .

[0082] like Figure 2 As shown, the revolution assembly includes a motor 3 1001, a driving gear 1002 and a driven gear 1003;

[0083] The driven gear 1003 is coaxially arranged with the screen 8. One side of the driven gear 1003 is rotatably mounted on the inner wall of the shredding chamber 2. The cleaning roller 1004 is connected to the other side of the driven gear 1003.

[0084] The third motor 1001 is located outside the second shredding chamber 2, and the driving gear 1002 is rotatably mounted inside the second shredding chamber 2. The third motor 1001 is connected to the driving gear 1002 to drive the driving gear 1002 to rotate inside the second shredding chamber 2;

[0085] The driving gear 1002 is meshed with the driven gear 1003 .

[0086] like Figure 2 As shown, a self-rotating assembly is provided between the cleaning roller 1004 and the driven gear 1003;

[0087] The self-rotation assembly is suitable for driving the cleaning roller 1004 to rotate while revolving around the screen 8 .

[0088] like Figure 2 As shown, the self-rotating assembly includes a connecting plate 1005, an outer gear disc 1006 and an inner gear disc 1007;

[0089] One side of the connecting plate 1005 is fixedly connected to the driven gear 1003, the outer gear disc 1006 is rotatably connected to the other side of the connecting plate 1005, and the cleaning roller 1004 is fixedly connected to the outer gear disc 1006;

[0090] The outer toothed disc 1006 is connected to the inner wall of the shredding chamber 2 2 , and the outer toothed disc 1006 is meshed with the inner toothed disc 1007 .

[0091] The working principle of this embodiment is as follows:

[0092] During the long shredding operation, a large number of unqualified fragments will inevitably be blocked in the mesh of the screen 8, which will affect the entire shredding operation. The operator needs to constantly clean the screen 8. During the cleaning process, the shredding operation also needs to be stopped, and the unqualified fragments in the screen 8 need to be temporarily removed, which is extremely inconvenient.

[0093] Therefore, after a period of work or while the shredding work is in progress, the cleaning assembly 10 can be started to clean the screen 8;

[0094] When the cleaning component 10 is started, the motor 3 1001 drives the driving gear 1002 to rotate, and the driven gear 1003 is rotated by the meshing between the driving gear 1002 and the driven gear 1003. The cleaning roller 1004 located on the driven gear 1003 will rotate in the direction of rotation of the driven gear 1003. The initial position of the cleaning roller 1004 is against the outer surface of the cleaning roller 1004, and the driven gear 1003 revolves around the center of the screen 8, thereby achieving the cleaning roller 1004 also revolving around the center of the screen 8, and the cleaning roller 1004 will continuously rub against the mesh of the screen 8 to push the debris stuck in the screen 8 back into the inside of the screen 8, thereby achieving a cleaning effect;

[0095] The screen 8 can be a hard brush;

[0096] On the basis of the cleaning roller 1004 revolving around the screen 8, the cleaning roller 1004 itself is rotatably installed on the connecting plate 1005 through the outer toothed disc 1006, and the connecting plate 1005 is fixedly connected to the driven gear 1003. Therefore, when the driven gear 1003 drives the cleaning roller 1004 to revolve, the cleaning roller 1004 itself is also rotatable. During the revolution, the outer toothed disc 1006 is engaged with the fixed inner toothed disc 1007, so that the outer toothed disc 1006 is also constantly rotating, thereby realizing the self-rotation of the cleaning roller 1004. The final effect is that the cleaning roller 1004 rotates while revolving, further improving the cleaning efficiency of the mesh of the screen 8. The entire shredding work does not require the operator to stop work many times to clean the screen 8, reducing labor while also improving the overall efficiency of the shredding work.

[0097] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
