Description

Technical Field

[0001] This utility model relates to the field of silo unblocking technology, and in particular to an unblocking device for silos blocked in crushers. Background Technology

[0002] The crusher hopper is a crucial component of the crusher system, primarily used for storing and uniformly feeding material. The hopper typically has a large capacity, capable of storing the material to be crushed and feeding it evenly into the crushing chamber through vibration or gravity. When material enters the crusher from the hopper, it must pass through the hopper's discharge port. However, to concentrate the material, the discharge port is often designed with a small opening, making the connection between the hopper and the discharge port prone to blockage. Therefore, a clogging device for the crusher hopper is needed.

[0003] According to the Chinese patent "A Material Blockage Clearing Device for a Belt Conveyor Hopper" authorized announcement number "CN218113738U", when material is blocked, the system automatically starts an electric push rod when the blockage sensor is triggered and a blockage signal is emitted. The push rod enters the clearing pipe and impacts the blocked material back and forth to clear the hopper. This changes the original manual assisted clearing method. By adopting mechanical clearing and automated program control, it can react quickly, greatly improve efficiency, and reduce the time affected by production.

[0004] Although the aforementioned application can receive signals through a blockage sensor when the unblocking pipe is blocked, and then use an electric push rod to impact the blocked part back and forth to unblock the unblocking pipe, the device can only be detected when the unblocking pipe is completely blocked. When part of the unblocking pipe is blocked, the other part is still in the unblocking state. Although the hopper is still discharging material in this state, the working efficiency is greatly reduced. Therefore, the device has the problem that it can only unblock unblocking pipes that are completely blocked.

[0005] Therefore, a device for clearing blockages in crusher hoppers is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a device for clearing blockages in crusher hoppers in order to solve the above-mentioned problems, thereby improving the problem of not being able to clear partially blocked hoppers.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a unclogged material hopper unblocking device for a crusher, comprising: a spring plate installed on the inner wall of the hopper, wherein a limit rod is provided on the inner wall of the hopper, and the spring plate is rotatably connected to the limit rod;

[0008] A dredging mechanism includes two first cylinders, two second cylinders, and two third cylinders disposed on the surface of the discharge port. The first cylinders are connected to the second cylinders, and the second cylinders are connected to the third cylinders. The first cylinders are rotatably connected to the discharge port, and the second and third cylinders are fixedly connected to the surface of the discharge port. The surface of the discharge port is provided with a telescopic component.

[0009] Preferably, a first piston is slidably connected to the inner wall of the first cylinder, and a first spring is fixedly connected between the first piston and the inner bottom wall of the first cylinder. The two first cylinders are disposed opposite each other on the surface of the discharge port. This prevents the first piston from sticking to the inner bottom wall of the first cylinder and losing its function.

[0010] Preferably, the second cylinder contains two second pistons, with a fixing block between them. The fixing block is fixedly connected to the inner wall of the second cylinder, and a second spring is fixedly connected between the fixing block and each of the two second pistons. The two second pistons are slidably connected to the inner wall of the second cylinder. This divides the second cylinder into four chambers, thereby adjusting the pressure.

[0011] Preferably, a third piston is slidably connected to the inner wall of the third cylinder, the top end of the third piston extending through the third cylinder and into the feed inlet, and the third cylinder is positioned below the second cylinder for easy unblocking.

[0012] Preferably, the telescopic assembly includes four first telescopic rods rotatably connected to the surface of the feed inlet. Second telescopic rods are slidably connected to the inner walls of the first telescopic rods. The second telescopic rods pass through the feed hopper and are hinged to the spring plate. A third spring is fixedly connected between the inner bottom walls of the second and first telescopic rods. This causes the spring plate to rotate repeatedly, preventing blockage.

[0013] Preferably, the four telescopic components are arranged in pairs on opposite sides of the discharge port, with the first cylinder positioned between each pair of telescopic components. This enhances the unblocking effect.

[0014] Preferably, the top of the first piston penetrates the feed hopper, and the top of the first piston is hinged to the spring plate. A pressure valve is installed in the connecting pipe between the second cylinder and the third cylinder to increase the impact force of the third piston.

[0015] The beneficial effects of this utility model are:

[0016] 1. The spring plate is hinged to the first cylinder. When a blockage occurs in the hopper, the spring plate is subjected to increased pressure and compresses the first cylinder, which increases the pressure in the first and second cylinders. When the pressure in the second cylinder reaches the preset value of the pressure valve, the third piston will clear the blockage. This device can clear the hopper as soon as a blockage occurs, avoiding the problem that it can only clear the blockage when it is completely blocked, thus affecting work efficiency.

[0017] 2. By setting up a telescopic component in conjunction with the spring plate, each change in pressure on the spring plate will cause it to rotate along the limit rod, thereby making the spring plate vibrate continuously, reducing the probability of blockage at the connection between the hopper and the discharge port, and improving work efficiency.

Detailed Implementation

[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] In practical implementation: such as Figure 1-4 As shown, a device for clearing blockages in a crusher hopper includes: a spring plate 100 installed on the inner wall of the hopper, a limit rod 200 provided on the inner wall of the hopper, and the spring plate 100 being rotatably connected to the limit rod 200.

[0025] The unblocking mechanism 300 includes two first cylinders 310, two second cylinders 320, and two third cylinders 330 disposed on the surface of the discharge port. The first cylinders 310 are connected to the second cylinders 320, and the second cylinders 320 are connected to the third cylinders 330. The first cylinders 310 are rotatably connected to the discharge port, and the second cylinders 320 and third cylinders 330 are fixedly connected to the surface of the discharge port. The surface of the discharge port is provided with a telescopic component 340.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, a first piston 311 is slidably connected to the inner wall of the first cylinder 310. A first spring 312 is fixedly connected between the first piston 311 and the inner bottom wall of the first cylinder 310. Two first cylinders 310 are arranged opposite each other on the surface of the discharge port. Two second pistons 322 are arranged inside the second cylinder 320. A fixing block 321 is arranged between the two second pistons 322. The fixing block 321 is fixedly connected to the middle inner wall of the second cylinder 320. A second spring 323 is fixedly connected between the fixing block 321 and each of the two second pistons 322. Both second pistons 322 are slidably connected to the first piston 311. The inner wall of the second cylinder 320 and the inner wall of the third cylinder 330 are slidably connected to a third piston 331. The top end of the third piston 331 passes through the third cylinder 330 and into the feed port. The third cylinder 330 is located below the second cylinder 320. The telescopic assembly 340 includes four first telescopic rods 341 rotatably connected to the surface of the feed port. The inner wall of the first telescopic rods 341 is slidably connected to a second telescopic rod 342. The second telescopic rods 342 pass through the feed hopper and are hinged to the spring plate 100. A third spring 343 is fixedly connected between the second telescopic rod 342 and the inner bottom wall of the first telescopic rod 341.

[0027] In this embodiment, the first cylinder 310, the third cylinder 330, and the telescopic assembly 340 are all inclined upwards. The connection between the first piston 311 and the second telescopic rod 342 through the hopper is provided with a strip-shaped opening. The width of the strip-shaped opening is greater than the width of the hinge between the first cylinder 310, the second telescopic rod 342, and the spring plate 100. When the spring plate 100 is compressed, the surface of the spring plate will move in a circular motion, which will drive the first cylinder 310 and the first telescopic rod 341 to rotate along the surface of the discharge port. The third cylinder 330 has a circular opening through the discharge port. The circular opening is larger than the diameter of the third piston 331. In the initial state, the third piston 331 and the inner wall of the discharge port are on the same plane.

[0028] like Figure 1 , Figure 2 and Figure 3As shown, four telescopic components 340 are arranged in pairs on opposite sides of the discharge port. A first cylinder 310 is positioned between each pair of telescopic components 340. The top of the first piston 311 penetrates the feed hopper and is hinged to the spring plate 100. A pressure valve is installed in the connecting pipe between the second cylinder 320 and the third cylinder 330. The fixing block 321 inside the second cylinder 320 is a circular block with the same diameter as the second piston 322. The fixing block 321 and the two second pistons 322 divide the second cylinder 320 into four chambers. The two chambers adjacent to the fixing block 321 are connected to the third cylinder 330 via two air pipes. At the same time, the pressure valve is located at the junction of the two air pipes.

[0029] In use, the material in the hopper falls down the hopper wall and enters the crusher through the feed port. When the material passes the surface of the spring plate 100, it applies pressure to the spring plate 100, causing the spring plate 100 to rotate along the limit rod 200. At the same time, it pushes the first piston 311 and the second telescopic rod 342. The second telescopic rod 342 compresses the third spring 343 and drives the first telescopic rod 341 to rotate. Since the material is in a moving state, the pressure on the surface of the spring plate 100 is different, which causes the third spring 343 to continuously contract and extend, causing the spring plate 100 to shake, thereby reducing the probability of hopper blockage.

[0030] When the hopper and discharge port become blocked, the pressure on the spring plate 100 continues to increase until the spring plate 100 is in contact with the hopper wall. The third spring 343 is continuously compressed and cannot extend. At this time, the pressure in the first cylinder 310 continues to increase. The first piston 311 compresses the first spring 312 and at the same time increases the pressure at both ends in the second cylinder 320. Simultaneously, it pushes the two second pistons 322 to move relative to each other and compress the two second springs 323, so that the pressure in the two chambers near the fixed block 321 in the second cylinder 320 gradually increases. When the pressure in the chamber reaches the preset value of the pressure valve, the gas in the second cylinder 320 rushes into the third cylinder 330. The third piston 331 in the third cylinder 330 moves upward rapidly and impacts and clears the blockage.

[0031] Once the blockage is cleared, the spring plate 100 loses pressure, the third spring 343 extends and pushes the spring plate 100, the pressure in the first cylinder 310 decreases, the two second springs 323 in the second cylinder 320 push the second piston 322 to push the gas in the second cylinder 320 back into the first cylinder 310, the pressure in the third cylinder 330 decreases, and under the pressure difference and the push of the material, the third piston 331 completes the reset.

[0032] It should be noted that the first spring 312, the second spring 323, and the third spring 343 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
