[0002] An impact crusher, also known as an impact breaker, is a device that uses high-speed rotating working parts to impact materials to achieve crushing; its working principle is based on the application of impact energy and plays a key role in the field of material crushing.
[0003] During the crushing process, the existing equipment can easily cause flying stones to fly out from the feeding end, which can easily lead to injury to workers. Although the existing equipment can be equipped with a cover plate, the cover plate needs to be opened every time it is fed and closed after feeding is completed, which is cumbersome. The existing equipment cannot screen the stones for secondary crushing, so its functionality is poor. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides a leak-proof impact crusher to solve the issues of existing devices where flying stones easily escape from the feeding end during the crushing process, potentially causing injury to workers. Although existing devices can be equipped with a cover plate, the cover plate needs to be opened each time material is fed and closed after feeding, making operation cumbersome. Furthermore, existing devices cannot screen stones for secondary crushing, resulting in poor functionality.

[0007] Furthermore, the crushing roller and the motor together form the first crushing assembly; the first base, the stop block, and the elastic block together form the blocking assembly.
[0008] Furthermore, a second crushing assembly is installed on the right end face of the inner wall of the crusher housing. The second crushing assembly consists of a second base, guide rods, a crushing seat, a helical spring, and crushing teeth. The second base is fixed to the right end face of the crusher housing by screws. Two guide rods slide on the second base. The lower end of each guide rod is welded to the crushing seat. A helical spring for buffering the crushing seat is sleeved on each guide rod.
[0009] Furthermore, the bottom end face of the crushing seat is welded with crushing teeth in a linear array. The crushing teeth have a triangular prism structure and are used during operation.
[0010] Furthermore, a second crushing component is also fixed on the left end face of the inner wall of the crusher box. The second crushing component fixed on the left end face of the inner wall of the crusher box is located at the upper left position of the second crushing component fixed on the inner wall of the crusher box, and the two second crushing components are arranged in an alternating manner.
[0011] Furthermore, a screen holder is inserted into the crusher housing, and a screen is fixed on the screen holder.
[0012] Furthermore, a baffle is inserted into the crusher housing, the baffle being located directly above the screen holder, and the baffle is made of iron.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] In terms of preventing material leakage and ensuring safety, the baffle in the blocking component can effectively block flying stones and prevent material leakage; the baffle is located directly above the screen base, which can prevent flying stones from damaging the screen and ensure the normal operation of the equipment, while also reducing the safety hazards caused by material scattering at the work site.
[0015] In terms of crushing effect, the motor drives the crushing roller in the first crushing component to achieve initial crushing; the two staggered second crushing components, using the triangular prism-shaped crushing teeth on the crushing seat, can further crush the splashed stone, significantly improving crushing efficiency and quality, and making the stone crushing more complete.
[0016] In terms of equipment protection and practicality, the helical spring in the second crushing component can buffer the impact of flying stones on the crushing seat, reducing the chance of damage to the crushing seat and extending the service life of the equipment; the screen on the screen seat can screen the crushed stones, making it easier to separate larger stones for further crushing, ensuring that the output particle size meets the requirements, and improving the practicality and applicability of the equipment.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.
[0026] Example 1: As shown in the attached document Figure 1 To be continued Figure 4 As shown:
[0027] This utility model provides a leakage-proof impact crusher, including a crusher housing 1; two concave support legs 101 are fixed on the crusher housing 1, a crushing roller 201 rotates on the crusher housing 1, and an electric motor 202 is fixed on the front end face of the crusher housing 1, with the output shaft of the electric motor 202 fixed on the crushing roller 201; when the electric motor 202 is started, the electric motor 202 drives the crushing roller 201 to rotate, thereby crushing the stone.
[0028] A first base 301 is fixed on the crusher housing 1 by a screw. An elastic block 303 is fixed on the bottom surface of the first base 301. A stop block 302 is attached to the bottom surface of the elastic block 303 by strong adhesive. During use, when the crushing roller 201 rotates to crush the stone, the stop block 302 can block the flying stones, thereby preventing material leakage.
[0029] The crushing roller 201 and the motor 202 together form the first crushing component 2; the first base 301, the stop block 302 and the elastic block 303 together form the blocking component 3.
[0030] The crusher housing 1 has a second crushing component 4 installed on the right end face of its inner wall. The second crushing component 4 consists of a second base 401, guide rods 402, a crushing seat 403, a helical spring 404, and crushing teeth 405. The second base 401 is fixed to the right end face of the crusher housing 1 by screws. Two guide rods 402 slide on the second base 401. The lower end of each guide rod 402 is welded to the crushing seat 403. Each guide rod 402 is fitted with a helical spring 404 for buffering the crushing seat 403. When stone splashes onto the crushing seat 403, the two helical springs 404 can buffer the stone, reducing the chance of damage to the crushing seat 403.
[0031] Among them, the bottom end face of the crushing seat 403 is welded with crushing teeth 405 in a linear array. The crushing teeth 405 are triangular prisms. During use, when the stone collides with the crushing teeth 405, the stone can be crushed again by the triangular prisms. The crushing effect of the triangular prisms is good.
[0032] Among them, a second crushing component 4 is also fixed on the left end face of the inner wall of the crusher box 1. The second crushing component 4 fixed on the left end face of the inner wall of the crusher box 1 is located at the upper left position of the second crushing component 4 fixed on the inner wall of the crusher box 1. The two second crushing components 4 are arranged in an alternating manner. During use, the setting of the two second crushing components 4 can improve the crushing effect and the anti-leakage effect.
[0033] The crusher housing 1 is equipped with a screen holder 6, on which a screen is fixed. During use, the screen on the screen holder 6 can be used to screen stones, making it easier to crush larger stones again later.
[0034] Example 2: Based on Example 1, a baffle 5 is inserted into the crusher housing 1. The baffle 5 is located directly above the screen base 6. The baffle 5 is made of iron. During use, the baffle 5 blocks the screen base 6, which can prevent the screen from being damaged by flying stones.
[0035] Working principle: During crushing, the stone is fed through the top of the crusher housing 1 and slides into the crushing roller 201. The motor 202 is started, and the motor 202 drives the crushing roller 201 to rotate and crush the stone. When the stone collides with the crushing teeth 405, the triangular prism-shaped crushing teeth 405 can further crush the stone. When the crushing roller 201 rotates and crushes the stone, the baffle 302 can block the flying stone pieces. After crushing, the baffle 5 is pulled out, and the stone is screened through the screen seat 6. The screened large stones can be crushed again.
