Description

Technical Field

[0001] This utility model relates to the field of crusher technology, and in particular to a door opening structure for the cavity of a plastic crusher. Background Technology

[0002] During operation, the blades of a plastic crusher will gradually become dull as the working time increases, resulting in a gradual decrease in output. Therefore, in order to ensure crushing efficiency, it is necessary to replace the crusher blades regularly.

[0003] Replacing blades in a traditional crusher requires using a hydraulic device to open the upper chamber, remove the screws securing the blades, and then take out the blades for replacement. Because the upper chamber plate is heavy, the space for blade replacement on the tilted side is limited, making blade replacement difficult. This traditional method is inefficient and poses certain safety hazards due to the tilting mechanism. If the hydraulic pump malfunctions during blade removal or installation, the upper chamber could easily close suddenly, creating a safety risk. Utility Model Content

[0023] like Figure 1-3As shown, the present invention proposes a plastic crusher cavity opening structure, including a crusher body 1 and a cavity door 2. The crusher body 1 has two first openings communicating with its inner wall at both ends. The cavity door 2 is rotatably disposed at the first opening. The cavity door 2 can be rotated to fit against the crusher body 1 to complete the sealing of the first opening.

[0024] In this invention, when using the device, the cavity door 2 can be rotated to fit against the crusher body 1 to seal the first opening, thereby enabling crushing operations. When maintenance is required on the blades inside the crusher body 1, the cavity door 2 can be rotated to open the first opening, making it convenient for workers to maintain the blades inside the crusher body 1. Moreover, the first opening is located on the side of the crusher body 1, which can effectively improve the safety of workers compared to the common top-opening type device.

[0025] In an optional embodiment, cylindrical hinges 3 are provided at both ends of the crusher body 1, and a connecting plate 4 is provided on the cavity door 2. The connecting plate 4 is connected to the cylindrical hinges 3. A limiting component is provided on the crusher body 1 for limiting the cavity door 2. The cavity door 2 can be effectively rotated and installed by the connecting plate 4 connected to the cylindrical hinges 3. After rotation, the stability of the cavity door 2 after rotation can be improved by the limiting component, thereby improving the stability of the device during operation.

[0026] In an optional embodiment, the limiting component includes a U-shaped groove 5, a mounting rod 8, and a locking plate 11. The U-shaped groove 5 is connected to the end of the machine cavity door 2 away from the cylindrical hinge 3. The mounting rod 8 is rotatably connected to the end of the crusher body 1 away from the cylindrical hinge 3 via a mounting unit. The locking plate 11 is slidably mounted on the mounting rod 8. The mounting rod 8 is provided with a driving unit for driving the locking plate 11 to move. The mounting rod 8 can rotate into the U-shaped groove 5, and the locking plate 11 can move to abut against the U-shaped groove 5. When it is necessary to limit the machine cavity door 2, first rotate the machine cavity door 2 to fit against the crusher body 1, and then rotate the mounting rod 8 to rotate into the U-shaped groove 5. The driving unit drives the locking plate 11 to move, and the locking plate 11 moves to abut against the U-shaped groove 5, thereby completing the limiting of the U-shaped groove 5 and thus completing the limiting of the machine cavity door 2.

[0027] In an optional embodiment, the mounting unit includes two mounting plates 6 and a rotating shaft 7. The two mounting plates 6 are spaced apart vertically and connected to the crusher body 1. One end of the mounting rod 8 is located inside the two mounting plates 6. A first through hole is provided on one end of the mounting rod 8. The rotating shaft 7 is disposed in the first through hole, and its two ends are respectively connected to the two mounting plates 6. The rotating shaft 7 is rotatably connected to the mounting rod 8. The mounting plates 6 and the rotating shaft 7 can effectively complete the installation of the mounting rod 8.

[0028] In an optional embodiment, the drive unit includes a threaded rod 9 and a nut 10. The mounting rod 8 is provided with the threaded rod 9, and the nut 10 is threaded onto the threaded rod 9. The nut 10 is rotatably connected to the clamping plate 11. When it is necessary to drive the clamping plate 11 to move, the nut 10 is rotated. Since the nut 10 is rotatably connected to the clamping plate 11 and is threadedly connected to the threaded rod 9, the nut 10 will drive the clamping plate 11 to move when it rotates.

[0029] In an optional embodiment, a first bolt 12 is further included. The crusher body 1 is provided with a plurality of first threaded blind holes spaced apart. The cavity door 2 is provided with a first notch that is equal in number to and corresponds one-to-one with the plurality of first threaded blind holes. One end of the first bolt 12 passes through the first notch and extends into the first threaded blind hole. The first bolt 12 is threadedly connected to the crusher body 1 and abuts against the cavity door 2. After limiting the cavity door 2, the first bolt 12 can also be inserted into the first threaded blind hole through the first notch and abut against the cavity door 2, thereby further limiting the cavity door 2 and improving the stability of the cavity door 2 when the device is in use.

[0030] In an optional embodiment, a fixing plate 13 and a second bolt 14 are also included. The fixing plate 13 is connected to the crusher body 1 and is located above the connecting plate 4. The fixing plate 13 is provided with a first threaded through hole. The second bolt 14 is threaded in the first threaded through hole. The second bolt 14 can be moved to abut against the connecting plate 4. After the cavity door 2 is rotated, the second bolt 14 can be rotated to abut against the connecting plate 4, thereby effectively limiting the connecting plate 4 to complete the limiting of the cavity door 2. This prevents the shaking of the cavity door 2 from affecting the maintenance work of the staff when they open the cavity door 2 to inspect the blades.

[0031] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof.
