DETAILED DESCRIPTION

[0020] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] like Figure 1 and Figure 2As shown, a PE pipe crusher according to an embodiment of the present invention comprises a rolling chamber 1 and a crushing chamber 2. The rolling chamber 1 is arranged above the crushing chamber 2, and the rolling chamber 1 and the crushing chamber 2 are preferably arranged coaxially. A first feed port 11 is arranged on the top of the rolling chamber 1, and a rolling mechanism and a cutting mechanism are arranged inside the rolling chamber 1. The rolling mechanism is located below the first feed port 11 to roll the pipe entering from the first feed port 11, and to roll irregular tubular pipes into sheet pipes; the cutting mechanism is arranged below the rolling mechanism to cut the rolled sheet pipes, and to cut the long strip pipes into multiple small sections, so as to facilitate further processing of each small section of pipes. Crushing; the bottom plate 18 of the rolling chamber 1 is rotatably connected to the side plates. When the bottom plate 18 of the rolling chamber 1 is fixed relative to the side plates so that the bottom plate 18 and the side plates are closed, the small sections of pipes cut by the cutting mechanism fall onto the bottom plate 18 for storage; when the bottom plate 18 of the rolling chamber 1 rotates relative to the side plates so that an opening is formed between the bottom plate 18 and the side plates, the formed opening can be used as a discharge port of the rolling chamber 1 to discharge the small sections of pipes stored on the bottom plate 18 into the crushing chamber 2 for further crushing. The crushing chamber 2 is provided with a crushing mechanism and a pushing mechanism. The bottom of the crushing chamber 2 is provided with a first discharge port 201. One side of the pushing mechanism is fixed to the side wall of the crushing chamber 2, and the other side of the pushing mechanism is fixed to the bottom plate 18 of the rolling chamber 1, so that the bottom plate 18 of the rolling chamber 1 can be opened or closed relative to the side plate, which facilitates the storage of a certain amount of pipes on the bottom plate 18 or the dropping of the pipes stored on the bottom plate 18 into the crushing chamber 2; the crushing mechanism is arranged below the bottom plate 18 to crush the pipes. The bottom plate 18 can be opened or closed by the pushing mechanism, so that when the pipes stored on the bottom plate 18 reach the set weight, the bottom plate 18 is opened to transfer the pipes to the crushing chamber 2, so that the crushing mechanism in the crushing chamber 2 can be started intermittently, so as to avoid the crushing mechanism in the crushing chamber 2 being in a working state all the time, thereby improving the service life of the crushing mechanism.

[0022] like Figure 1 and Figure 2As shown, in this embodiment, the rolling mechanism includes a rolling drive mechanism, a first rolling wheel 12 and a second rolling wheel 13, the first rolling wheel 12 and the second rolling wheel 13 are arranged opposite to each other, and the wheel axes of the first rolling wheel 12 and the second rolling wheel 13 are parallel to each other; the gap between the first rolling wheel 12 and the second rolling wheel 13 is located directly below the first feed port 11, so that after the pipe enters from the first feed port 11, it falls into the gap between the first rolling wheel 12 and the second rolling wheel 13, which facilitates the first rolling wheel 12 and the second rolling wheel 13 to roll the pipe; the rolling drive mechanism is connected to the first rolling wheel 12 and the second rolling wheel 13 to drive the first rolling wheel 12 and the second rolling wheel 13 to roll in the direction of the gap. The rolling directions of the first rolling wheel 12 and the second rolling wheel 13 are opposite, as shown in FIG. Figure 2 As shown, the first rolling wheel 12 rolls clockwise, and the second rolling wheel 13 rolls counterclockwise, so that the first rolling wheel 12 and the second rolling wheel 13 roll the pipe while transferring the pipe downward.

[0023] It should be noted that the rolling drive mechanism may be a drive motor, and the driving method of the first rolling wheel 12 and the second rolling wheel 13 is conventional, which will not be described in detail in the present invention.

[0024] In this embodiment, the cutting mechanism includes a first cutting unit and a second cutting unit, and the first cutting unit and the second cutting unit are arranged opposite to each other. It should be pointed out that the structures of the first cutting unit and the second cutting unit are exactly the same. Taking the first cutting unit as an example, the first cutting unit includes a cutting drive mechanism 14, a plurality of electric push rods 15 and a plurality of cutters 16. The cutting drive mechanism 14 is arranged on the side plate of the rolling chamber 1, and the plurality of electric push rods 15 are arranged side by side at intervals. One end of each of the electric push rods 15 is connected to the cutting drive mechanism 14, and the other end of each of the electric push rods 15 is connected to a cutter 16. The cutting drive mechanism 14 drives the electric push rods 15 to drive the corresponding cutter 16 to reciprocate, so that the cutter 16 completes the cutting of the pipe in the process of reciprocating motion, and cuts the pipe into a plurality of small sections. Furthermore, the plurality of cutters 16 of the first cutting unit and the plurality of cutters 16 of the second cutting unit are arranged in an up-and-down staggered manner to avoid missing the cutting of the pipe and to avoid interference between the cutters 16 when they are extended and retracted. It should be noted that the electric push rod 15 of the first cutting unit and the electric push rod 15 of the second cutting unit are extended and retracted synchronously. When the electric push rod 15 of the first cutting unit is extended, the electric push rod 15 of the second cutting unit is extended synchronously, so as to clamp the pipe between the two cutting units and facilitate cutting of the pipe. When the pipe entering from the first feed port 11 is a small section of pipe, there is no need to cut the small section of pipe, then the electric push rod 15 of the first cutting unit and the electric push rod 15 of the second cutting unit can be shortened synchronously, so that the pipe falls into the gap between the first cutting unit and the second cutting unit, thereby avoiding ineffective operation of the cutting mechanism and increasing the service life of the cutting mechanism.

[0025] It should be noted that the cutting drive mechanism 14 can be a drive motor.

[0026] Preferably, a second feed port 17 is provided on the side plate of the rolling chamber 1, and the second feed port 17 is located below the cutting mechanism. For small sections of pipes, they can be placed directly in the rolling chamber 1 from the second feed port 17 without passing through the rolling mechanism and the cutting mechanism.

[0027] In this embodiment, the push mechanism includes a push drive mechanism 21 and a push rod 22. The push drive mechanism 21 is installed on the side wall of the crushing chamber 2. One end of the push rod 22 is fixed to the bottom plate 18, and the other end of the push rod 22 is connected to the push drive mechanism 21. The push drive mechanism 21 drives the push rod 22 to extend and retract. The push rod 22 is extended to press against the bottom plate 18 of the rolling chamber 1, so that the bottom plate 18 of the rolling chamber 1 is relatively fixed to the side plate, which is convenient for the storage of pipes on the bottom plate 18 of the rolling chamber 1; when the push rod 22 is shortened, it drives the bottom plate 18 of the rolling chamber 1 to rotate relative to the side plate, so that a discharge port is formed between the bottom plate 18 and the side plate, which is convenient for the pipes stored on the bottom plate 18 to fall into the crushing chamber 2 for further crushing.

[0028] It should be noted that the push driving mechanism 21 can be a driving motor.

[0029] It should be noted that, in the present invention, the bottom plate 18 of the grinding chamber 1 is a part of the top plate of the crushing chamber 2, and the bottom plate 18 of the grinding chamber 1 and the side plates can be connected by hinges or hinges.

[0030] In this embodiment, the crushing mechanism includes a crushing drive mechanism, a first crushing unit and a first transmission unit 25, the first crushing unit includes a plurality of first rollers 23 arranged side by side, the axle axes of the plurality of first rollers 23 are parallel to each other, and are preferably arranged in the same plane; each first roller 23 is circumferentially provided with a plurality of first roller cutters 24, and the first roller cutters 24 of adjacent first rollers 23 are meshed with each other to fully crush and crush the pipe; the axles of adjacent first rollers 23 are connected by a belt 29, the axle of one of the first rollers 23 is connected to the first transmission unit 25, the first transmission unit 25 is connected to the crushing drive mechanism, the crushing drive mechanism drives the first transmission unit 25 to rotate, and utilizes the belt 29 to drive the plurality of first rollers 23 to rotate, while the first roller 23 rotates, the first roller cutter 24 performs primary crushing and cutting on the pipe.

[0031] Preferably, the first roller cutters 24 are evenly arranged along the circumference of the first roller wheel 23 to evenly crush the pipe.

By performing two-stage rolling and cutting on the pipe, on the one hand, the pipe can be crushed more thoroughly, and on the other hand, the pipe can be crushed into small pieces by the first-stage rolling and cutting, and the small pieces of pipe can be further crushed by the second-stage rolling and cutting, which can reduce the wear of the pipe on the crushing mechanism and increase the service life of the crushing mechanism.

[0034] Preferably, the second roller cutters 27 are evenly arranged along the circumference of the second roller 26 to evenly crush the pipe.

[0035] Further, preferably, the number of the first rollers 23 is smaller than the number of the second rollers 26, and the intervals between the first roller cutters 24 on the first roller 23 are larger than the intervals between the second roller cutters 27 on the second roller 26, so that the first roller 23 can realize primary crushing of the pipe, and the second roller 26 can realize secondary crushing of the pipe. The diameters of the first roller 23 and the second roller 26 can be equal or different.

[0036] In this embodiment, the first roller cutter 24 and the second roller cutter 27 are both straight-knife shaped. In other embodiments, the first roller cutter 24 and the second roller cutter 27 can also be curved-knife shaped, respectively curved toward the rotation direction of the corresponding first roller wheel 23 or the second roller wheel 26.

When the pipe stored on the bottom plate 18 of the rolling chamber 1 reaches a certain weight, the push drive mechanism 21 drives the push rod 22 to extend and retract, so that the bottom plate 18 of the rolling chamber 1 rotates relative to the side plate, so that a discharge port is formed between the bottom plate 18 and the side plate, and the pipe enters the crushing chamber 2 from the discharge port. The first transmission unit 25 is driven by a pulverizing drive mechanism to drive multiple first rollers 23 to rotate. During the rotation of the multiple first rollers 23, the first roller cutters 24 engage with each other to perform primary pulverization on the pipes.
