[0002] A toothed claw crusher is a device that uses the impact, shearing, and grinding action between high-speed rotating toothed claws and fixed toothed claws to crush materials. It is widely used in grain, feed, chemical, and pharmaceutical fields. The core working components are the movable toothed claws mounted on the rotor and the fixed toothed claws on the casing. After the material enters the crushing chamber, it is rapidly crushed under the action of the high-speed relative motion of the toothed claws. It features a compact structure, high crushing efficiency, and uniform particle size of the finished product. It is suitable for processing medium to low hardness materials such as grains, beans, and Chinese medicinal herbs.

[0003] Chinese patent CN220371158U discloses a toothed claw type pulverizer, including a machine body and a pulverizing chamber disposed on the machine body.

It also includes a rotating shaft, rotating toothed discs, and a door. The rotating shaft is rotatably disposed within the pulverizing chamber, and the rotating toothed discs are distributed along the circumference of the rotating shaft and mounted on the rotating shaft, rotating with it. One end of the door is hinged to the pulverizing chamber, and a second fixed toothed disc is disposed on the side of the door near the pulverizing cavity. The rotating toothed discs extend into the first and second fixed toothed discs respectively, and the rotating toothed discs, the first fixed toothed disc, and the second fixed toothed disc together form a pulverizing space.

Detailed Implementation

[0025] Reference Figure 1As shown, this utility model provides a technical solution: a toothed claw crusher, including a main support 1, a toothed claw crusher body 2 fixedly connected to the upper end of the main support 1, a feed inlet 3 connected and fixedly connected to the upper side of the toothed claw crusher body 2, a discharge outlet 4 connected and fixedly connected to the lower side of the toothed claw crusher body 2, a screening structure 5 provided on the side wall of the main support 1, and a locking structure 6 provided on the surface of the sliding frame 51.

[0026] The following section will explain the specific setup and function of its screening structure 5 and locking structure 6.

[0027] Reference Figures 1-3 As shown in this embodiment: the screening structure 5 includes a limiting strip 52 fixedly connected to the side wall of the main support 1. A sliding frame 51 is slidably connected to the side wall of the limiting strip 52, and a screen frame 53 is fixedly connected to the side wall of the sliding frame 51. The surface of the screen frame 53 is provided with several second screen holes 56. By setting the screening structure 5, it is convenient to screen the material after crushing according to the crushing requirements. The screened material can be crushed again until the crushing requirements are met, which improves the crushing quality of the material to a certain extent. A drawer plate 54 is slidably connected to the inner side of the screen frame 53. The surface of the drawer plate 54 is provided with several first screen holes 55. When the material enters the screen frame 53, the material with a particle size smaller than the second screen hole 56 can pass directly through the screen hole and become a qualified finished product, while the material with a larger particle size is intercepted and falls to the other side of the screen frame 53. The first screen hole 55 and the second screen hole 56 are both diamond-shaped holes. By changing the overlapping area of ​​the first screen hole 55 and the second screen hole 56, the larger the overlapping area, the larger the particle size of the material that can pass through, and vice versa. A connecting strip 57 is fixedly connected to the side wall of the sliding frame 51. A bolt 58 is threaded inside the connecting strip 57, and the bolt 58 is rotatably connected to the internal part of the draw plate 54. When the bolt 58 is tightened or loosened, the draw plate 54 will slide along the inner side of the screen frame 53.

[0028] Reference Figures 1-2 and Figures 4-5 As shown, specifically, the locking structure 6 includes a support rod 62 fixedly connected to the surface of the sliding frame 51. A pin 63 is slidably connected inside the support rod 62. Several circular grooves 61 are formed on the surface of the limiting strip 52, the size of which matches the size of the pin 63. By setting the locking structure 6, the flexible locking operation of the screen frame 53 after it has moved from below the discharge port 4 is facilitated, improving the stability of the screen frame 53 after movement to a certain extent. A retaining ring 64 is fixedly connected to the side wall of the pin 63, and a pull block 66 is fixedly connected to the end of the pin 63. Pulling the pull block 66 causes the pin 63 to slide along the support rod 62. A spring 65 is fitted onto the surface of the pin 63, with both ends of the spring 65 fixedly connected to the retaining ring 64 and the support rod 62, respectively. Releasing the pull block 66 resets the spring 65 and pushes the retaining ring 64, causing the pin 63 to insert into the corresponding circular groove 61 on the surface of the limiting strip 52.

[0029] Working principle: The material to be processed is fed into the toothed claw crusher body 2 through the feed inlet 3. Inside the crushing chamber of the toothed claw crusher body 2, the rotor drives the movable toothed claws to rotate at high speed, forming a high-speed relative motion with the fixed toothed claws on the casing. The material is crushed through impact, shearing and grinding. The crushed material is discharged from the discharge outlet 4 on the lower side of the crusher body under the action of gravity. The material discharged from the discharge outlet 4 falls directly into the screen frame 53 below, and the screening structure 5 begins to function. The surface of the screen frame 53 is provided with a second screen hole 56, and the inner side of the sliding plate 54 is connected to the screen. The screen has a first screen hole 55. When material enters the screen frame 53, particles smaller than the overlap area between the first screen hole 55 and the second screen hole 56 can pass through the screen hole directly and become qualified finished products. Larger particles are cut off and fall to the other side of the screen frame 53. If the screening particle size needs to be adjusted, it can be achieved by rotating the bolt 58 on the connecting bar 57. The bolt 58 is rotatably connected to the sliding plate 54. When the bolt 58 is tightened or loosened, the sliding plate 54 will slide along the inner side of the screen frame 53, changing the overlap area between the first screen hole 55 and the second screen hole 56. The larger the overlap area, the larger the particle size of the material that can pass through. Conversely, the larger the size, the better, thus adapting to different crushing needs. The screen frame 53 is slidably connected to the limiting strip 52 on the side wall of the main support 1 via the sliding frame 51. It can move along the limiting strip 52 according to operational needs. After moving to the target position, the locking structure 6 is activated and fixed. Pulling the pull block 66 can drive the pin 63 to slide along the support rod 62. At this time, the retaining ring 64 compresses the spring 65, positioning the screen frame 53. After releasing the pull block 66, the spring 65 returns to its original position and pushes the retaining ring 64, causing the pin 63 to insert into the corresponding circular groove 61 on the surface of the limiting strip 52, thus achieving stable fixing of the screen frame 53 and preventing over-screening. During the process, the screen frame 53 shifts due to vibration. Large particles intercepted by the screen frame 53 can be collected and fed back into the crusher body through the feed inlet 3 to undergo crushing and screening again until the particle size meets the requirements, thus achieving complete crushing of the material. This solves the problem of low efficiency caused by incomplete crushing in traditional crushers. The entire working process, through the cooperation of the screening structure 5 and the locking structure 6, not only ensures that the particle size of the crushed material is controllable, but also improves the crushing quality through the secondary processing mechanism. At the same time, the stability design of the locking structure 6 ensures the reliable operation of the screening.
