[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0017] Example 1: Reference Figure 1-3 The double-roll crusher includes a base 8, a shell 1 is fixedly connected to the base 8, two crushing rollers 2 are rotatably connected to the shell 1 through bearings, the two crushing rollers 2 are connected by a transmission mechanism, and a filter screen 11 is obliquely fixedly connected to the shell 1. The filter screen 11 is used to intercept and filter incompletely crushed materials, so that unqualified materials pass through the filter screen 11 through the discharge chute 13 and enter the movable platform 5.
[0018] A discharge chute 13 is provided on the shell 1, and a connecting shell 4 is fixedly connected to the shell 1. A moving platform 5 is abutted inside the connecting shell 4. The moving platform 5 is moved by a moving mechanism, and the moving mechanism drives the moving platform 5 to move, so that the upper end of the moving platform 5 moves to the top of the shell 1. The moving platform 5 blocks the discharge chute 13 to ensure that the crushing continues. The material on the moving platform 5 can be pushed down and re-crushed, so that the incompletely intercepted material can be collected and re-crushed.
[0019] The transmission mechanism includes a gear 14, and the two crushing rollers 2 are fixedly connected with the gear 14, and the two gears 14 are meshed with each other. The shell 1 is fixedly connected with a first motor 3, and the output shaft of the first motor 3 is transmission-connected to one of the crushing rollers 2, and is rotated by the first motor 3. Under the transmission of the two gears 14, the two crushing rollers 2 rotate in opposite directions for crushing.
[0020] The moving mechanism includes a second motor 6, which is installed on a base 8. A threaded rod 7 is rotatably connected to the output shaft of the second motor 6. A threaded hole is provided on the moving platform 5, and the threaded rod 7 is threadedly connected to the threaded hole. The second motor 6 is rotated to drive the threaded rod 7 to rotate, thereby adjusting the position of the threaded rod 7 in the threaded hole, so as to adjust the position of the moving platform 5.
[0021] An inclined surface 12 is provided at the upper end of the movable platform 5 . The design of the inclined surface 12 plays a labor-saving role so as to push the materials on the movable platform 5 down into the housing 1 .
[0022] Embodiment 2: In embodiment 1, since the filter 11 may be blocked and the filter 11 is located inside the device, it is inconvenient to clean the filter 11. Referring to Figures 1-4, as another preferred embodiment of the utility model, on the basis of embodiment 1, a cleaning port is provided on the shell 1, and support edges 10 are fixedly connected to both sides of the cleaning port. Limiting grooves are provided on the opposite inner sides of the two supporting edges 10, and sealing plates 9 are slidably provided in the two limiting grooves. The sealing plate 9 is driven to slide in the limiting groove by moving the sealing plate 9, thereby opening the cleaning port and cleaning the filter 11 to prevent blockage.
[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
