[0030] The unloading mechanism 5 includes a right-angle plate 51, which is fixedly connected to the right side of the shell 2. A hydraulic rod 52 is fixedly connected to the inner side of the right-angle plate 51, and a baffle 53 is fixedly connected to the left end of the hydraulic rod 52. A support platform 55 is fixedly connected to the right side of the support frame 7, and a hydraulic rod 2 56 is fixedly connected to the top of the support platform 55. The left end of the hydraulic rod 2 56 is fixedly connected to a fixed box 57, and the right side of the fixed box 57 is fixedly connected to a motor 58. The output end of the motor 58 is fixedly connected to an output shaft 59, and a drive component 501 is provided on the outer wall of the output shaft 59. A threaded rod 502 is provided inside the drive component 501, and a rectangular plate 503 is threadedly connected to the outer wall of the threaded rod 502. A fixed shaft 504 is fixedly connected to the left side of the rectangular plate 503, and a limited frame 54 is fixedly connected to the left end of the fixed shaft 504.

[0031] Furthermore, the threaded rod 502 is rotatably connected to the inner wall of the fixed box 57 , and the threads on the outer walls at both ends of the threaded rod 502 are in opposite directions, so that the rotational motion of the threaded rod 502 is converted into the linear motion of the rectangular plate 503 .

[0032] Furthermore, the driving assembly 501 includes a driving bevel gear and a driven bevel gear, the output shaft 59 is fixedly connected to the inner ring of the driving bevel gear, the threaded rod 502 is fixedly connected to the inner ring of the driven bevel gear, and the driving bevel gear and the driven bevel gear are meshed with each other, thereby achieving the purpose of stable transmission.

[0033] Furthermore, the output shaft 59 passes through the fixed box 57 and rotates. A long slot is opened on one side of the fixed box 57, and the fixed shaft 504 passes through the long slot, so that the fixed shaft 504 can move through the long slot.

[0034] Furthermore, a feeding opening is provided at the bottom of the fixing frame 1 , and a baffle 53 is movably connected to the inner side of the feeding opening, thereby being able to block the feeding opening.

[0035] Example 2

[0036] See Figures 1 to 5 On the basis of Example 1, the limiting mechanism 6 is further obtained to include a fixed block 61, the fixed block 61 is fixedly connected to the outside of the support frame 7, the fixed block 61 is movably connected to a movable block 62 inside, the outside of the support frame 7 is fixedly connected to a connecting shaft 64, and the outer wall of the connecting shaft 64 is rotatably connected to a limiting plate 63 to ensure the stability of the limited collection of the conveying vehicle 4.

[0037] Furthermore, the movable block 62 is fixedly connected to the outside of the transport vehicle 4 , and the limiting plate 63 is movably connected to the outside of the movable block 62 , so that the movable block 62 cannot be easily moved.

[0038] During actual operation, when this device is used, first, the waste chips generated by the CNC engraving machine can be discharged into the interior of the shell 2 through the upper hopper 3, and then the hydraulic cylinder 8 can be started to work, and the hydraulic cylinder 8 can drive the pressure plate 9 to move, so that the pressure plate 9 can compress the waste chips. When the waste chips are compressed into blocks, the hydraulic rod 52 can be started to work, and the hydraulic rod 52 can drive the baffle 53 to move to the right, so that the discharge port opened at the bottom of the shell 2 can leak out, so that the block-shaped waste chips can fall into the interior of the support frame 7, and then the motor 58 can be started to work, and the output end of the motor 58 can drive the output shaft 59 to rotate, and the output shaft 59 can drive the threaded rod 502 to rotate through the transmission of the drive assembly 501. Since the rectangular plate 503 can fix the inner wall of the box 57 to slide and limit, and the threaded rod 502 and the rectangular plate 503 are threadedly connected When the block of waste chips is moved to the inside of the conveyor 4, the hydraulic rod 56 is stopped and the motor 58 is started again to reverse, so that the limit frame 54 can cancel the clamping of the block of waste chips, and then the block of debris can fall into the inside of the conveyor 4 for collection, without the need for manual handling operations, thereby reducing the situation where waste chips easily cut the staff and reducing the safety hazards in the transportation process.

[0039] When the interior of the transport trolley 4 is full of waste chips, the limit plate 63 can be rotated along the axis point of the connecting shaft 64, so that the limit plate 63 can cancel the limit on the movable block 62. At this time, the movable block 62 can be pulled out from the interior of the fixed block 61 through the transport trolley 4, and the limit on the transport trolley 4 is canceled, which is convenient for the transfer operation of the waste chip blocks inside the transport trolley 4. Similarly, the limit on the transport trolley 4 can also be achieved to ensure the stability of the transport trolley 4 in the process of collecting waste chips, and it will not easily cause deviation and shaking, which is convenient for the further development of waste chip work.
