[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This utility model adopts a two-stage crushing design. The upper crushing mechanism initially crushes the plastic tray, and the lower crushing mechanism further refines the plastic particles, ensuring that the crushed plastic particles reach the ideal size and improving crushing efficiency and quality.

[0013] 2. In the crushing process, the negative pressure generated by the dust extraction fan draws the dust through the dust extraction pipe and collects it in the dust collection box, effectively reducing dust leakage and reducing environmental pollution.

[0014] 3. This utility model is equipped with an installation strip and a magnet on the discharge port of the lower crushing chamber. The magnet can adsorb ferromagnetic impurities, such as iron filings, that may be mixed in during the crushing process, thereby effectively improving the purity of the final plastic particles and ensuring product quality.

[0022] The following is a description of the embodiments and appendices. Figures 1-4 The technical solution of this utility model will be further described below.

[0023] Example 1

[0024] A plastic pallet crushing device includes: a frame 1, on which a crushing mechanism 2 is provided. The crushing mechanism 2 is provided in two sets, and the two sets of crushing mechanisms 2 are arranged vertically and each includes a crushing motor 21, a crushing chamber 22 and a crushing roller 23. The crushing roller 23 is rotatably disposed in the crushing chamber 22 and one end of it passes through the crushing chamber 22 and is drivenly connected to the output end of the crushing motor 21. The upper end of the crushing chamber 22 of the upper crushing mechanism 2 is provided with a feeding chamber 3. The upper end of the feeding chamber 3 is provided with a dust removal mechanism 4. The dust removal mechanism 4 includes a sealing cover 41 slidably disposed on the upper end of the crushing chamber 22, a dust suction pipe 42 connected to the sealing cover 41, and a dust collection box 43 connected to the other end of the dust suction pipe 42. The discharge port of the upper crushing chamber 22 is sealed and connected to the inlet of the lower crushing chamber 22.

[0025] like Figures 1-4 As shown, the operator first slides open the sealing cover 41, places the waste plastic pallet to be processed into the feeding hopper 3, and then closes the sealing cover 41 to ensure a tight seal. Next, the crushing motor 21 and the dust extraction fan are started simultaneously. The crushing roller 23 of the upper crushing mechanism begins to rotate under the drive of the motor, performing the first stage of crushing the plastic pallet. At the same time, the negative pressure generated by the dust extraction fan draws the dust generated during the crushing process through the dust extraction pipe 42 and collects it in the dust collection box 43, effectively reducing dust leakage and maintaining a clean working environment.

[0026] After initial crushing, the material falls into the lower crushing chamber 22 under the influence of gravity. The lower crushing roller 23, driven by the crushing motor 21, also performs a second stage of crushing treatment on the material, further refining the plastic particles.

[0027] As a further preferred embodiment, a plastic enclosure 51 is provided outside the discharge port of the crushing chamber 22 located on the lower side, and a trolley 6 is provided on the lower side of the frame 1. The distance between the plastic enclosure 51 and the ground is a, and the height of the trolley 6 is b, satisfying the quantitative relationship: a>b.

[0028] Specifically, the plastic enclosure located outside the discharge port of the lower crushing chamber works in conjunction with the trolley 6 on the lower side of the frame, and the distance a between the plastic enclosure and the ground is greater than the height b of the trolley. This ensures that the crushed plastic particles can be smoothly discharged and collected by the trolley, avoiding particle scattering and waste. At the same time, it facilitates the timely transfer of processed plastic particles by the operator, improving the practicality and working efficiency of the entire crushing device.

[0029] As a further preferred embodiment, the crushing roller 23 is provided in two sets, and each set of crushing rollers 23 is provided with meshing transmission teeth 231 on the side away from the crushing motor 21.

[0030] As a further preferred embodiment, an installation strip 221 is provided on the discharge port of the crushing chamber 22 located on the lower side, and a magnet 222 is provided on the installation strip 221.

[0031] Specifically, magnet 222 can adsorb ferromagnetic impurities, such as iron filings, that may be mixed in during the crushing process, thereby improving the purity of the final plastic particles.

[0032] As a further preferred embodiment, the mounting strip 221 and magnet 222 are provided in two sets.

[0033] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
