Description

Technical Field

[0001] This utility model relates to the field of crusher blade technology, specifically a crusher blade assembly. Background Technology

[0002] A crusher is a machine that crushes large solid raw materials to the required size. A crusher consists of coarse crushing, fine crushing, and pneumatic conveying devices, achieving its crushing purpose through high-speed impact. It utilizes wind power to produce powder in one pass, eliminating the traditional screening process. It is mainly used in mining, building materials, and other industries. An existing patent, patent publication number CN207025509U, discloses a crusher blade assembly, including a mounting component and multiple blades. The mounting component includes a mounting tube and two limiting plates fixed to both ends of the mounting tube. The blades are mounted on the side of the mounting tube and located between the two limiting plates. The limiting plates prevent the blades from shifting axially along the mounting tube. Fixing bolts pass through the limiting plates and the blades, and multiple blade particles are fixed on the blades. The blade assembly of this utility model crusher includes multiple blades, and multiple blade particles are fixed on the blades. Because the blade particles are small in size, they can crush smaller materials. Therefore, after the blades crush the material, the blade particles crush the material again to obtain smaller materials, thus avoiding the situation where previous crushers could not crush smaller materials and greatly improving the crushing effect of the equipment.

[0003] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: In practical applications, due to the inconvenience of disassembly and assembly, workers need to spend a lot of manpower and time on disassembly and assembly during subsequent use, which reduces the ease of use of the tool assembly and makes it inconvenient for subsequent normal use. Therefore, we propose a tool assembly for a crusher to solve the above-mentioned problems. Utility Model Content

[0013] Beneficial effects

[0014] This invention provides a blade assembly for a crusher. Compared with the prior art, it has the following advantages:

[0015] The blade assembly of this crusher allows for easy replacement of the blade by loosening the screw on the hexagonal block, which then separates the screw from the blade. Simultaneously, pulling the stop block moves the insert rod, separating it from the components inside the mounting tube. This facilitates subsequent disassembly and assembly, improving the ease of use of the assembly and making it more convenient for installers and operators.

[0016] Meanwhile, the anti-slip plate increases the friction between the tool holder and the tool disc.
