[0002] Plastic crusher refers to the equipment that crushes various plastics and rubbers, such as plastic profiles, tubes, rods, wires, films, and waste rubber products. The equipment that crushes them is called a crushing device. The crushing device produces a lot of noise during the use process because it is in the process of stirring and crushing plastics. Although the existing technology can reduce the noise during the crushing process, it still has the defect of high noise during use, such as:
[0003] In the prior art, after the plastic is crushed, the cover needs to be opened to discharge the crushed plastic. The current discharge method is direct discharge. During discharge, since the discharge port is directly connected to the outside, the crushed plastic will be discharged in piles. During the discharge process, a large noise will still be generated due to the flow state.
[0004] Therefore, the prior art does not have the condition of diverting discharge, because the discharge port is connected to the outside, resulting in the plastic being discharged outward in piles, which makes a lot of noise and spreads the noise in the external environment, and cannot effectively reduce the noise generated during the discharge process. Therefore, there is an urgent need for a plastic crushing device that can divert the discharge process to reduce noise. Utility Model Content
[0005] The utility model aims at the deficiencies of the prior art and provides the following technical solutions:

DETAILED DESCRIPTION
[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.
[0024] Please refer to Figure 1-Figure 6 As shown, the utility model provides a plastic crushing device capable of reducing noise, comprising a bottom plate 1, a crushing box 2 with a bottom opening, and a collecting box 3 with a top opening, the outer periphery of the bottom end of the crushing box 2 is slidably sleeved in the collecting box 3, and the collecting box 3 is slidably arranged on the top surface of the bottom plate 1;
[0025] A material discharge plate 24 inclined toward the axis is fixedly provided on the inner wall of the crushing box 2, and a material discharge opening 241 is opened at the axis of the material discharge plate 24;
[0026] A hemispherical material dividing plate 22 is slidably arranged on the inner wall of the crushing box 2 near the bottom end, the top end of the material dividing plate 22 is slidably blocked in the material discharge port 241, and a material discharge hole is opened at the bottom edge of the material dividing plate 22;
[0027] A crushing mechanism for crushing plastic is arranged in the space enclosed between the top of the unloading plate 24 and the crushing box 2 .
[0028] In the present case, by inserting the bottom of the crushing box 2 into the collecting box 3, the bottom of the crushing box 2 can be sealed, and the crushing box 2 and the collecting box 3 can be communicated. When in use, the collecting box 3 is placed under the crushing box 2, and then the bottom of the crushing box 2 can be inserted into the collecting box 3 by sliding the crushing box 2, so that the crushing box 2 and the collecting box 3 are communicated. At this time, by moving the dividing plate 22, the top of the dividing plate 22 can be blocked in the feed opening 241, and the feed opening 241 is sealed to prevent plastic from falling through the feed opening 241 during the crushing process. Then, the plastic is introduced into the crushing box 2 from the feed opening set on the top surface of the crushing box 2, and the plastic can be crushed by the crushing mechanism.
[0029] After the plastic is crushed, the discharge port 241 can be released by moving the dividing plate 22, and the top of the dividing plate 22 no longer blocks the discharge port 241. At this time, the top surface of the discharge plate 24 is inclined to facilitate the plastic to slide downward, so that the crushed plastic can fall onto the dividing plate 22 through the discharge port 241. The dividing plate 22 is hemispherical in structure to facilitate the falling plastic to fall along the dividing plate 22 and fall into the collecting box 3 from multiple directions. The crushed plastic is divided and dropped to avoid falling in piles at the same time. The outer periphery of the dividing plate 22 is arc-shaped, which can reduce the impact force during the falling process, avoid direct collision, and reduce the noise during the sliding process. The intermittent closed discharge process is adopted to avoid the generation of large smoke and dust in the outside world during the discharge process to prevent affecting the external environment. At the same time, it can reduce the propagation of large noise in the external environment and improve the utilization efficiency of the plastic crushing device.
[0030] The crushing box 2 and the collecting box 3 are made of the same material, and are both sound-insulating materials.
[0031] By using the same material for the crushing box 2 and the collecting box 3, noise can be effectively reduced. The noise reduction function of the crushing box 2 is a common technology in the prior art, so the present invention does not record the noise reduction structure of the crushing box 2 and how to reduce noise.
[0032] A limit baffle 12 is fixedly disposed on the top surface of the bottom plate 1 and is in contact with the collection box 3 . The limit baffle 12 is an arc-shaped structure.
[0033] The limiting baffle 12 is provided to limit the collecting box 3, wherein the limiting baffle 12 is an arc-shaped structure, and the outer periphery of the collecting box 3 abuts against the limiting baffle 12, so as to facilitate the positioning of the collecting box 3. When in use, the collecting box 3 is placed on the top surface of the bottom plate 1 and then pushed so that the collecting box 3 abuts against the limiting baffle 12, thereby effectively positioning the collecting box 3 and ensuring that the collecting box 3 is directly below the crushing box 2, so that the bottom end of the crushing box 2 can be inserted into the collecting box 3.
[0034] Both sides of the top surface of the base plate 1 are provided with height adjustment mechanisms for driving the crushing box 2 to slide up and down. The height adjustment mechanism includes a hydraulic telescopic rod 11 and a connecting plate 21. The bottom end of the hydraulic telescopic rod 11 is fixedly connected to the top surface of the base plate 1, and the top end of the hydraulic telescopic rod 11 is fixedly connected to the connecting plate 21. The connecting plate 21 is fixedly connected to the outer periphery of the crushing box 2.
[0035] The connection plate 21 can be driven to move by starting the hydraulic telescopic rod 11 , and the connection plate 21 is fixedly connected to the crushing box 2 , so that the height of the crushing box 2 can be changed by starting the hydraulic telescopic rod 11 .
[0036] A stopper 23 is fixedly connected to the inner wall of the crushing box 2 near the bottom end to prevent the material dividing plate 22 from sliding down.
[0037] By setting the stopper 23 , the dividing plate 22 can be blocked to prevent the dividing plate 22 from falling into the collecting box 3 .
[0038] The crushing mechanism includes a rotating rod 4, a rotating motor 41 and crushing leaves 42. The rotating motor 41 is fixedly arranged at the axis center of the top surface of the crushing box 2. The power output end of the rotating motor 41 is inserted into the crushing box 2 and fixedly connected to the rotating rod 4. The crushing leaves 42 are spirally wound and fixed on the outer periphery of the rotating rod 4. The bottom end of the rotating rod 4 passes through the dividing plate 22, and the rotating rod 4 and the dividing plate 22 are slidably connected through bearings.
[0039] The crushing leaves 42 are provided to facilitate the crushing cutting of the plastic in the crushing box 2 and the crushing of the plastic. The bottom end of the rotating rod 4 passes through the dividing plate 22. At the same time, the rotating rod 4 and the dividing plate 22 are slidably connected by bearings, so that the dividing plate 22 can be both slidably connected to the rotating rod 4 and rotatably connected. The rotating rod 4 can also limit the dividing plate 22 to avoid the dividing plate 22 from tilting and to avoid the unloading port 241 from being blocked during use.
[0040] A scraping rod 43 for scraping the crushed materials on the top surface of the blanking plate 24 is fixedly arranged on the periphery of the rotating rod 4 .
[0041] Through the setting of the scraper rod 43, when the rotating rod 4 is in a rotating state, it can drive the scraper rod 43 to rotate. At this time, the scraper rod 43 can scrape the fragments on the top surface of the discharge plate 24, and by scraping the fragments, the fragments can be splashed during the scraping process, so that the crushing leaves 42 can crush and cut the fragments again, thereby improving the crushing efficiency and avoiding the deposition of plastic on the top surface of the discharge plate 24 when the plastic is crushed. At the same time, when the crushed plastic is exported, the scraper rod 43 can also scrape the fragments on the discharge plate 24 through the slow rotation of the rotating rod 4, which has a cleaning effect on the discharge plate 24 to prevent it from affecting reuse and improve the use efficiency.
[0042] A power mechanism for driving the dividing plate 22 to move up and down is arranged at the axis center of the collecting box 3, and the power mechanism includes an electric telescopic rod 31 and a supporting sleeve rod 311. The electric telescopic rod 31 is fixedly connected to the bottom end of the inner wall of the collecting box 3, and the top of the electric telescopic rod 31 is fixedly connected to the supporting sleeve rod 311. The top of the supporting sleeve rod 311 is provided with a socket that is plugged into the outer periphery of the rotating rod 4.
[0043] Through the setting of the electric telescopic rod 31 and the supporting sleeve rod 311, when in use, the collecting box 3 is placed on the top surface of the bottom plate 1, and then the collecting box 3 is slid, which can make the collecting box 3 collide with the limit baffle 12. At this time, the supporting sleeve rod 311 corresponds to the rotating rod 4. By starting the electric telescopic rod 31, it is convenient to make the supporting sleeve rod 311 sleeved on the periphery of the rotating rod 4, and make the top end of the supporting sleeve rod 311 collide with the dividing plate 22. As the supporting sleeve rod 311 moves, the rotating rod 4 can slide in the supporting sleeve rod 311.

It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the technical solution of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
