[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0017] Depend on Figures 1 to 6 It is known that a raw material crushing device for HDPE recycled pipes includes a box body 1, a feed inlet 2 at the top of the box body 1, a discharge outlet 3 at the bottom of the box body 1, a pair of crushing rollers 4 rotatably arranged inside the box body 1, a baffle 5 above the crushing rollers 4, the baffle 5 is inclined above, a feeding area is formed in the middle of the baffle 5, and an extrusion plate 6 is arranged inside the baffle 5. The extrusion plate 6 can extend and retract to crush the raw material in the feeding area.

[0018] In practical use, this utility model

[0019] The recycled pipeline raw material is fed into the box 1 through the feed inlet 2. The raw material enters the crushing roller 4 through the feed area formed by the baffle 5. It is crushed under the action of the crushing roller 4 and finally discharged from the discharge outlet 3, thus completing the crushing process.

[0020] When the raw material is too large to enter the crushing rollers 4, the extrusion plate 6 moves towards the center to crush the raw material, reducing its volume so that it can smoothly enter the crushing rollers 4 to complete the crushing.

[0021] The crushing roller 4 is provided with crushing teeth on the circumference, the crushing teeth are engaged with each other to complete the crushing of the raw materials, the crushing roller 4 is provided with a transmission gear 7 at the end, the crushing roller 4 is provided with a hexagonal hole 8 at the end, the box 1 is provided with a driving motor 9 outside for driving the crushing roller 4, the output shaft of the driving motor 9 is a hexagonal column 10 capable of cooperating with the hexagonal hole 8, the hexagonal column 10 of the driving motor 9 is inserted into the hexagonal hole 8 to drive the crushing roller 4, the crushing roller 4 is connected through the transmission gear 7 at the end, and the two crushing rollers 4 are engaged to complete the crushing of the raw materials.

[0022] The extrusion plate 6 is provided with a plurality of teeth 11 outside at intervals, the teeth 11 of the two extrusion plates 6 are engaged with each other, the baffle 5 is provided with a stop block 12 at the bottom for cooperating with the teeth 11, the box 1 is provided with a hydraulic cylinder 13 outside connected with the extrusion plate 6, and the hydraulic cylinder 13 controls the extension and retraction of the extrusion plate 6.

[0023] When the raw materials cannot enter the crushing roller 4 in the feeding area, the entering of the remaining raw materials is affected, and the crushing efficiency is greatly affected, at this time, the hydraulic cylinder 13 is started, the hydraulic cylinder 13 drives the extrusion plate 6, the teeth 11 outside the extrusion plate 6 are engaged with each other, the raw materials in the regeneration pipeline are broken into small pieces, and then smoothly enter the crushing roller 4, and then are crushed into smaller particles by the crushing roller 4, so as to be reused.
