Description

Technical Field

[0001] This utility model relates to the field of crushers, and in particular to a vibrating anti-clogging device for crushers. Background Technology

[0002] The working principle of a crusher is mainly to crush materials through high-speed impact, cutting, or crushing. It is widely used in mining, building materials, chemical and other industries for the crushing and refining of raw materials. However, when using a crusher for the crushing process, the material often accumulates and blocks the feed pipe before or after crushing. Therefore, a vibrating device is usually added to the feed pipe to prevent material blockage. For example, a coal crusher anti-blocking device (publication announcement number CN221268484U) disclosed on the China Patent Network shows that when a large number of coal blocks are squeezed inside the guide shroud during the crushing process, the vibrating motor installed on the outer wall of the anti-blocking shroud will drive the anti-blocking shroud to vibrate left and right along the piston rod. This can shake the coal blocks inside the guide shroud and quickly guide a large number of coal blocks into the crusher.

[0003] However, the aforementioned patented anti-clogging devices for crushers and existing market applications still have some shortcomings: The existing method of using a single vibrating motor to drive mechanical vibration of the coal feeding pipe to prevent clogging is not very efficient and is slow in clearing accumulated blockages in the feeding pipe. Therefore, those skilled in the art have provided a vibrating anti-clogging device for crushers to solve the problems mentioned in the background section. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a vibratory anti-clogging device for crushers, which solves the problem of low anti-clogging efficiency in existing crusher feed pipes mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a vibrating anti-blocking device for a crusher, including a feeding hopper; The hopper has vibrators installed symmetrically on both sides of its walls, and a spring seat mechanism is installed on the top of its hopper. The bottom of the hopper of the feeding bin is equipped with a hammer vibration mechanism in a symmetrical manner; The elastic seat mechanism includes a bottom support plate and a top support plate that are horizontally opposite each other. A damping rubber ring is provided between the bottom support plate and the top support plate, and multiple sets of vibration seats are arranged circumferentially between the bottom support plate and the top support plate. The hammer vibration mechanism includes an impact shell, one side of which is rotatably connected to an impact flap on the inner wall of the pressure cover hopper, and an impact braking assembly opposite to the impact flap is installed inside the impact shell.

[0006] As a further technical solution of this utility model: the damping rubber ring is a bellows structure.

[0007] As a further technical solution of this utility model: the vibration seat includes a vibration spring, the bottom end of the vibration spring seat is provided with a bottom support stud that is fixedly connected to the bottom support plate, and the top end of the vibration spring seat is provided with a top support stud that is fixedly connected to the top support plate.

[0008] As a further technical solution of this utility model: the hammer braking assembly includes a flipping shaft rotatably connected to the middle of the impact shell and a telescopic electric push rod installed symmetrically inside the impact shell in a direction perpendicular to the flipping shaft. Multiple sets of support arms are arranged on the outer side of the flipping shaft, and each set of support arms has an impact hammer head opposite to the impact flap at the bottom of the arm.

[0009] As a further technical solution of this utility model: both ends of the shaft of the flipping shaft are provided with transmission gears, and the telescopic end of the telescopic electric push rod is provided with a telescopic rack that meshes with the transmission gears.

[0010] As a further technical solution of this utility model: a time relay is installed on the housing of the vibrator.

[0011] This utility model provides a vibratory anti-clogging device for a crusher, which has the following advantages compared with the prior art: The anti-clogging device for the crusher designed in this paper is based on the elastic support of the spring seat mechanism for the feeding bin. Under the mechanical vibration of the vibrator on the feeding bin, an elastic assembly is formed. On the one hand, it improves the vibration efficiency of the feeding bin and reduces the clogging situation. On the other hand, it forms an elastic connection to reduce the hard vibration impact caused by mechanical vibration on the crusher. Simultaneously, the hammer vibration based on the hammer vibration mechanism can vibrate the material at the feeding port of the feeding bin synchronously to further reduce the clogging situation. It forms a double-linkage anti-clogging component and improves the anti-clogging performance of the crusher's feeding pipe. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3 This utility model provides a technical solution for a vibratory anti-clogging device for a crusher: The vibratory anti-clogging device for a crusher includes a feeding bin 1. Vibrators 6 are symmetrically installed on both sides of the bin wall of the feeding bin 1. A time relay is installed on the housing of the vibrator 6. By installing a time relay on the vibrator 6, the amplitude and vibration time of the vibrator 6 can be adjusted according to the material output of the crusher to speed up the feeding rate of the feeding bin 1 and avoid accumulation and blockage.

[0016] A spring seat mechanism is installed on the top of the hopper of feeding bin 1; The bottom of the hopper 1 is symmetrically equipped with a hammer vibration mechanism. The elastic seat mechanism includes a horizontally opposite bottom support plate 2 and a top support plate 5. A damping rubber ring 4 is provided between the bottom support plate 2 and the top support plate 5. The damping rubber ring 4 is a corrugated pipe structure. By using the damping rubber ring 4 to seal the bottom support plate 2 and the top support plate 5, it can serve as a material discharge channel to prevent side leakage when the material is discharged. On the other hand, it can also serve as an elastic buffer component to reduce the hard vibration impact of the hopper 1 transmitted to the crusher, thus playing an elastic buffer protection role.

[0017] Multiple sets of vibrating seats 3 are arranged circumferentially between the bottom support plate 2 and the top support plate 5. Each vibrating seat 3 includes a vibrating spring 31. The bottom end of the spring seat of the vibrating spring 31 is provided with a bottom support stud 32 that is fixedly connected to the bottom support plate 2, and the top end of the spring seat of the vibrating spring 31 is provided with a top support stud 33 that is fixedly connected to the top support plate 5. By setting the vibrating seat 3 between the bottom support plate 2 and the top support plate 5, the elastic extension and resetting of the vibrating spring 31 serves as a connecting component to connect the feeding bin 1 to the crusher, and as an elastic buffer to reduce the hard vibration impact of the feeding bin 1 transmitted to the crusher, thus providing elastic buffer protection.

[0018] The hammer vibration mechanism includes an impact shell 7. An impact flap 8 is rotatably connected to the inner wall of the pressure cover discharge hopper 1 on one side of the impact shell 7. A hammer braking assembly, opposite to the impact flap 8, is installed inside the impact shell 7. The hammer braking assembly includes a tilting shaft 10 rotatably connected to the middle of the impact shell 7 and telescopic electric push rods 9 symmetrically installed inside the impact shell 7, perpendicular to the direction of the tilting shaft 10. Multiple sets of support arms 11 are arranged on the outer side of the tilting shaft 10, and each set of support arms 11 has an impact hammer head 12 at its bottom end, opposite to the impact flap 8. Both ends of the tilting shaft 10 are equipped with… The telescopic end of the transmission gear 14 and the telescopic electric push rod 9 is provided with a telescopic rack 13 that meshes with the transmission gear 14. By controlling the telescopic electric push rod 9 to extend and brake, the telescopic rack 13 is pushed to extend and retract. The telescopic rack 13 and the transmission gear 14 mesh to convert the extension force into rotational force, which drives the flip shaft 10 to rotate. This, in turn, drives the combination of the support arm 11 and the impact hammer 12 to swing and rotate, striking the impact flip plate 8. The vibration force generated by the striking is used to hammer and vibrate the material at the bottom of the discharge bin 1 and accumulated on the impact flip plate 8, achieving the effect of hammering and vibration unloading, thereby reducing the blockage of the discharge bin 1.

[0019] The working principle of this utility model is as follows: When using the anti-blocking device as the feeding pipe of the crusher, the anti-blocking device is integrally installed at the feeding port of the crusher using the top support plate 5, and the combination of the damping rubber ring 4 and the vibrating seat 3 serves as an elastic connection channel between the feeding bin 1 and the crusher, so as to reduce the hard vibration impact transmitted to the crusher when the feeding bin 1 undergoes subsequent mechanical vibration, thus playing an elastic protection role. Then, when the feeding bin 1 is used to feed the crusher material, the vibrator 6 is controlled to work, and under the elastic support of the combination of the damping rubber ring 4 and the vibrating seat 3, the feeding bin 1 is made to vibrate elastically, and the material inside is vibrated to unload. The further controllable telescopic electric push rod 9 extends and brakes, driving the telescopic rack 13 to extend and retract. Utilizing the meshing transmission between the telescopic rack 13 and the transmission gear 14, the telescopic force is converted into rotational force, driving the tilting shaft 10 to rotate. This, in turn, drives the combination of the support arm 11 and the impact hammer 12 to tilt and rotate, striking the impact flap 8. The vibration force generated by the striking is used to hammer and vibrate the material at the bottom of the discharge hopper 1 and accumulated on the impact flap 8, achieving a hammering vibration unloading effect. Following this hammering method, the material is repeatedly hammered, achieving a dual-form vibration unloading effect.
