Description

Technical Field

[0001] This utility model relates to the field of crusher technology, specifically a medium-sized single-shaft crusher. Background Technology

[0002] Single-shaft crushers are widely used in various industrial fields, such as waste treatment, resource recycling, environmental protection, and waste recycling. They are designed to meet customer requirements for crushing various medium-sized materials, and adjustments are made to torque, speed, operating procedures, blade configuration, and structural strength for different material processing applications.

[0003] The existing technology has the following defects or problems: Existing technology, publication number CN220346063U, discloses a single-shaft crusher, including support legs and a casing. The support legs are fixedly installed on the lower end face of the casing. A feed hopper is provided at the top of the casing. A cutter box assembly is fixedly installed inside the casing. A cutter shaft is rotatably connected inside the cutter box assembly. Crushing blades are provided on the cutter shaft. One end of the cutter shaft penetrates through the side wall of the casing and is fixedly connected to a pulley assembly. The pulley assembly is fixedly connected to a drive wheel via a transmission belt. A motor is located at the center of the drive wheel. The single-shaft crusher of this application uses PLC automatic control and star-delta starting. The starting method is adjusted to frequency conversion starting or servo mode to reduce the impact of high-power motor starting on the power grid. Simultaneously, a human-machine interface is used to monitor the working status of the motor and crusher in real time, intelligently control the pressing device, and achieve visual operation, making operation simple, intuitive, and more user-friendly.

[0004] During operation, the aforementioned equipment directly drives the main shaft and cutter roller via pulleys, resulting in high main unit speed, low torque, and easy splashing and jamming when crushing materials. However, in existing technologies, some single-shaft crushers require manual pushing of materials to the crushing area, which wastes manpower, and the splashing materials during the crushing process can easily cause injury to workers.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figure 1-4 In this embodiment: a medium-sized single-shaft crusher includes a load box 1, a support plate 2 fixedly connected to the left side of the load box 1, a reduction motor 3 fixedly connected to the top of the support plate 2, a drive shaft 4 fixedly connected to the output end of the reduction motor 3, a drive gear 6 fixedly connected to the outside of the drive shaft 4, a gearbox 5 fixedly connected to the left side of the load box 1, a speed limiter 7 fixedly connected inside the gearbox 5, a speed limiter 8 rotatably connected to the outside of the speed limiter 7, a driven shaft 9 rotatably connected inside the load box 1, a driven gear 10 fixedly connected to the left side of the driven shaft 9, the external teeth of the drive gear 6 and the external teeth of the driven gear 10 being meshed, and the driven shaft 9... An external cutter roller 11 is provided, and a screen 12 is fixedly connected inside the load box 1. An adjustment component for adjusting the angle of the cutter roller 11 is provided outside the driven shaft 9. The adjustment component includes the driven shaft 9, and two mounting slots 13 are opened on the outside of the driven shaft 9. Multiple damping rods 14 are fixedly connected inside the two mounting slots 13, and multiple springs 15 are respectively sleeved on the outside. Connecting blocks 16 are slidably connected inside the two mounting slots 13, and limit strips 17 are fixedly connected at the front and rear ends. Multiple slots 24 are opened inside the cutter roller 11. The outside of the two connecting blocks 16 will engage with the inner wall of the multiple slots 24. A feeding component is provided inside the rear side of the load box 1.

[0026] In this embodiment, after the geared motor 3 starts as the power source, its output end drives the drive shaft 4 to rotate, and the drive gear 6 on the drive shaft 4 also rotates accordingly. Since the drive gear 6 is meshed with the driven gear 10, the rotation of the drive gear 6 will drive the driven gear 10 to rotate, thereby driving the driven shaft 9 to rotate, providing power for the rotation of the cutter roller 11. During this process, the speed limiting rod 7 and the speed limiting gear 8 in the gearbox 5 play the role of limiting and regulating the speed, ensuring that the speed of the driven shaft 9 is within a suitable range to meet the crushing requirements. Under normal working conditions, the connecting block 16 is subjected to the elastic force of the spring 15 and the resistance of the damping rod 14 in the mounting groove 13. The connecting block 16 is held in a stable position, tightly engaging with the groove 24 inside the cutter roller 11. This ensures that the cutter roller 11 can rotate stably with the driven shaft 9 for effective crushing. When the angle of the cutter roller 11 needs to be adjusted, a certain force can be applied externally to make the connecting block 16 slide within the mounting groove 13, overcoming the elastic force of the spring 15 and the resistance of the damping rod 14. This changes the engagement position of the connecting block 16 and the groove 24, thereby adjusting the angle of the cutter roller 11. The adjusted cutter roller 11 can better adapt to the crushing requirements of different materials or continue to be used after the blades wear out by adjusting the angle, thus extending the service life of the blades.

[0027] Example 2

[0028] like Figure 1 - Figure 4 As shown, the feeding assembly includes a support block 18. The upper and lower ends of the support block 18 are fixedly connected to the inner wall of the rear top of the load box 1. An electric telescopic rod 19 is fixedly connected inside the support block 18. A push plate 20 is fixedly connected to the output end of the electric telescopic rod 19. The bottom end of the push plate 20 contacts the inner wall of the top of the load box 1. The outer sides of two limit blocks 22 are slidably connected to the inner walls of two slide grooves 23. Multiple rubber strips 21 are fixedly connected to the front end of the push plate 20. Limit blocks 22 are fixedly connected to the left and right sides of the push plate 20. Slide grooves 23 are opened on the left and right sides of the top of the load box 1.

[0029] In this embodiment, the electric telescopic rod 19 receives a start signal and begins to extend. As the electric telescopic rod 19 extends, it pushes the push plate 20 forward. The push plate 20 can only move in a straight line along the direction defined by the slide groove 23, thereby ensuring the stability of the feeding process and preventing the push plate 20 from deviating during the pushing process. This allows the material to be pushed evenly to the crushing area. The rubber strip 21 has a certain degree of flexibility and friction, which can better fit the material and increase the contact area with the material, ensuring that the material can be effectively pushed.

[0030] The working principle and usage process of this utility model are as follows: First, the reduction motor 3 is started, and its output end drives the drive shaft 4 to rotate. The drive gear 6 on the drive shaft 4 also rotates accordingly. Since the drive gear 6 is meshed with the driven gear 10, the rotation of the drive gear 6 drives the driven gear 10 to rotate, which in turn drives the driven shaft 9 to rotate, providing power for the rotation of the cutter roller 11. Then, the electric telescopic rod 19 is started. As the electric telescopic rod 19 extends, it pushes the push plate 20 forward. The push plate 20 can only move in a straight line along the direction defined by the slide groove 23, thereby ensuring the stability of the feeding process and preventing the push plate 20 from deviating during the pushing process, so that the material can be pushed evenly to the crushing area. Finally, when it is necessary to adjust the angle of the cutter roller 11, a certain force can be applied externally to make the connecting block 16 slide in the mounting groove 13 against the elastic force of the spring 15 and the resistance of the damping rod 14, thereby changing the engagement position of the connecting block 16 and the slot 24, and realizing the adjustment of the angle of the cutter roller 11.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
