Description

Technical Field

[0001] This utility model belongs to the field of crusher technology, and in particular relates to an anti-impact device for the feed cylinder wall plate. Background Technology

[0002] In the crushing and processing of materials such as ores and construction waste, a two-stage crushing method is often used. That is, limestone crushed by a jaw crusher is conveyed by a conveyor belt to the next crusher for secondary crushing. When the limestone particles enter the feed inlet of the crusher, the impact on the wall plate will cause severe wear to the feed cylinder wall plate.

[0003] To improve the service life of the second crusher, an anti-impact device is installed at the feed position to buffer the crushed stone. However, traditional anti-impact devices are difficult to effectively absorb the high-intensity impact force generated by the crusher when crushing materials, which can easily lead to fatigue damage of related components inside the crusher due to long-term impact. In addition, traditional anti-impact devices themselves are also prone to damage under long-term impact. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide an anti-impact device for the feed cylinder wall plate, which aims to solve the problem that existing anti-impact devices are difficult to effectively absorb the high-intensity impact force generated by the crusher when crushing materials, which easily leads to fatigue damage of related components in the crusher due to long-term impact, and the traditional anti-impact device itself is also prone to damage under long-term impact.

[0005] The present invention adopts the following technical solution:

[0006] The anti-impact device of the feed cylinder wall panel includes an impact box, an impact bucket rotatably installed inside the impact box, a row of support rods on both the left and right sides of the impact bucket on the inner wall of the impact box, and the support rods support the impact box. A pair of oval grooves are opened on the back of the impact box, and a pair of locking sleeves are provided on the upper back of the impact bucket. Locking screws are inserted into the oval grooves and screwed into the locking sleeves. An observation port is opened on the back of the impact box above the impact bucket, and an observation cover is provided on the observation port.

[0007] Furthermore, a row of reinforcing plates is provided along the length of the impact bucket, and a partition is provided above the reinforcing plates.

[0008] Furthermore, a lifting handle is provided above the impact bucket.

[0009] Furthermore, the impact chamber is provided with skirts on both the left and right sides, and the support rod supports the impact box through the skirts.

[0010] The beneficial effects of this utility model are:

[0011] 1. In the initial state, a certain amount of crushed stone is pre-stored in the impact bucket as a buffer layer. When the limestone that has been initially crushed is continuously fed, the crushed stone first falls on the buffer layer and then falls into the crusher to achieve buffering.

[0012] 2. The structural design of the support rods, skirts, reinforcing plates, and partitions greatly enhances the stability and strength of the entire impact protection device, ensuring its reliable operation under long-term and frequent impacts. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0018] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0019] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0020] Combination Figure 1-4 As shown, the anti-impact device of the feed cylinder wall panel includes an impact box 1, an impact bucket 2 is rotatably arranged inside the impact box, a row of support rods 3 are arranged on the left and right sides of the inner wall of the impact box 1, and the support rods 3 support the impact box 1. A pair of oval grooves 4 are opened on the back of the impact box 1, and a pair of locking sleeves 5 are arranged on the upper back of the impact bucket 2. Locking screws 6 are inserted into the oval grooves 4 and screwed into the locking sleeves 5. An observation port is opened on the back of the impact box 1 above the impact bucket 2, and an observation cover 8 is provided on the observation port.

[0021] In the crushing and processing of materials such as ores and construction waste, multi-stage crushing is often used. After being crushed by a first crusher, the material is conveyed by a conveyor belt to a second crusher for further crushing. To improve the service life of the crushers, an anti-impact device can be installed at the feed position of the second crusher. After the crushed stone enters the second crusher, the anti-impact device provides a buffer, reducing the direct impact of the crushed stone on the feed cylinder wall.

[0022] In practical applications, the impact box is installed at the inlet of the second crusher. After the ore or other materials are crushed by the first crusher, the crushed stone is conveyed by the conveyor belt into the impact box and first laid inside the impact bucket. The crushed stone accumulates layer by layer to form an impact cushion, which provides continuous buffering. In this way, the service life of the impact bucket can be improved, and fatigue damage to the feed cylinder wall and related components inside the crusher due to long-term impact can be avoided.

[0023] In this device, the impact bucket 2 has skirts 9 on both its left and right sides, and the support rod 3 supports the impact box 1 through the skirts. The skirts increase the contact area between the impact bucket and the support rod, while limiting the lateral sway of the impact bucket and ensuring a stable feeding trajectory. This makes the crushed stone more stable during the feeding process.

[0024] As a specific structure, such as Figure 4 The impact bucket 2 has a row of reinforcing plates 10 arranged along its length, and a partition plate 11 is arranged above the reinforcing plates 10. The arrangement of the reinforcing plates and the partition plate significantly enhances the structural strength of the impact bucket, making it less prone to deformation and damage when subjected to material impact.

[0025] In this device, the observation port is used to monitor the material accumulation status inside the impact hopper in real time, preventing buffer failure due to blockage or overload. During maintenance, opening the observation cover allows for a direct inspection of the wear condition of components such as the impact hopper and locking screws, improving maintenance efficiency.

[0026] Because the impact bucket is equipped with a lifting handle 12, when the second crusher has also completed the further crushing of the crushed stone, if you want to empty the crushed stone accumulated in the impact bucket, you should first unscrew the two locking screws, then open the observation cover, and finally use the lifting handle to rotate the impact bucket forward, so that the crushed stone in the impact bucket can fall into the crusher.

[0027] In addition, the impact bucket will rotate slightly up and down during the crushing process. At that time, the locking screw will move up and down in the corresponding oval groove. The oval groove provides a space for movement and, with the cooperation of the locking screw, achieves buffering without affecting the overall stability of the device.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
