Specific implementation mode

[0028] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0029] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present invention.

[0030] See Figure 1 , Figure 2 , Figure 3 and Figure 4 , the present invention provides a hammer mill, including:

[0031] the machine base 1, the crushing body 2, the motor 3, the rotating shaft 5, the fixed knife 10, the hammer blade 11 and the screen bracket 12;

[0032] The crushing body 2 and the motor 3 are both fixedly installed on the top of the machine base 1. The rotating shaft 5 is rotatably installed on the crushing body 2. The fixed knife 10 and the hammer blade 11 are fixedly installed on the rotating shaft 5. The screen bracket 12 is fixedly installed inside the crushing body 2. It should be noted that the screen bracket 12 is used to install the screen, and the crushed material can fall through the screen after meeting the requirements.

[0033] With the above structure, the material to be crushed is added into the crushing body 2. The motor 3 is started, and the motor 3 drives the rotating shaft 5 to rotate through the coupling 4. The rotating shaft 5 drives the fixed knife 10 and the hammer blade 11 to rotate. The hammer blade 11 and the fixed knife 10 cooperate to produce a shearing and friction crushing effect on the material, improving the crushing accuracy and effect, increasing the number of times the hammer blade 11 strikes the material, maximizing the crushing of the material, and improving the production efficiency. The rotating shaft 5 can rotate forward and backward. The fixed knife 10 has a double-edge design. The alternating forward and reverse rotation makes the wear of the fixed knife 10 on the rotating shaft 5 more uniform, extending its service life. Since the single-direction rotation is likely to cause excessive wear on one side edge of the hammer blade 11, the reverse rotation side can balance this wear and ensure the stable operation of the equipment.

[0034] Specifically, guiding blocks 8 are fixedly arranged on the front side and the rear side of the machine base 1. A maintenance door 9 is horizontally slidably mounted on the guiding blocks 8. The maintenance door 9 is fixedly connected to the crushing body 2 through bolts. A control handle is fixedly arranged on the maintenance door 9. It should be noted that it is convenient for the horizontal movement of the maintenance door 9 to expose the front and rear two surfaces of the crushing body 2, facilitating the maintenance of the interior of the crushing body 2.

[0035] Specifically, a coupling 4 is fixedly arranged at the output end of the motor 3. The coupling 4 is fixedly connected to the rotating shaft 5. A bearing seat 6 is fixedly arranged on the top of the machine base 1. The rotating shaft 5 is installed on the bearing seat 6. It should be noted that it is convenient for the rotating shaft 5 to rotate.

[0036] Specifically, a feed inlet 7 is opened at the top of the crushing body 2, and a discharge hole is opened at the bottom of the crushing body 2. It should be noted that it is convenient for the addition of the material to be crushed and the discharge of the crushed material. The material to be crushed can be waste paper, wood, fiberglass, straw, branches, grains and other materials.

[0037] Specifically, a plurality of shock absorbers are fixedly arranged at the bottom of the machine base 1. It should be noted that it is convenient for shock absorption treatment of the crusher.

[0038] Specifically, the fixed knife 10 and the hammer blade 11 are arranged alternately. The hammer blade 11 uses manganese steel as the matrix material, and the edge of the hammer blade 11 is welded with tungsten carbide. The fixed knife 10 uses manganese steel as the matrix material, and high-speed steel is inlaid at the edge of the fixed knife 10. It should be noted that it can extend the service life of the hammer blade 11, reduce the maintenance cost, and improve the wear resistance and high heat resistance of the fixed knife 10.

[0039] The above has introduced in detail a hammer mill provided by the present utility model. Specific embodiments are used herein to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
