[0015] As Figs. 1-2As shown, a modified hammer head for a hammer crusher, comprising a mounting disc 1, a transmission shaft 2 and a plurality of hammer head bodies 3, the mounting disc 1 is disc-shaped, the transmission shaft 2 penetrates the mounting disc 1, and the plurality of hammer head bodies 3 are uniformly spaced and mounted on the edge of the mounting disc 1, the hammer head body 3 comprises a hammer handle 31, a main body 32, a reinforcing ring 33 and a stop seat 34, one end of the hammer handle 31 is movably connected with the edge of the mounting disc 1, the other end of the hammer handle 31 is connected with the main body 32, the cross section of the main body 32 is square, a plurality of reinforcing rings 33 are arranged side by side on the main body 32, the end of the main body 32 away from the hammer handle 31 is provided with a hollow position, and the stop seat 34 is detachably mounted on the hollow position for stopping the reinforcing ring 33. Specifically, the mounting disc 1 is sleeved on the transmission shaft 2 and located in the crushing cavity, when the rotating shaft 2 rotates under the drive of the motor, it can drive the mounting disc 1 to rotate, and in turn drive the hammer head bodies 3 mounted on the edge of the mounting disc 1 to rotate. The number of mounting discs 1 can be one or multiple groups arranged side by side on the transmission shaft 2, which is determined according to the volume of the crushing cavity and is not limited here. The hammer head body 3 is movably mounted on the mounting disc 1, so that the hammer head body 3 can swing around the connection with the mounting disc 1, avoiding hard collision with the materials in the crushing cavity, which is easy to cause stress fracture of the hammer head body 3. The hammer head body 3 comprises a hammer handle 31, a main body 32, a reinforcing ring 33 and a stop seat 34, the main body 32 is the main part of the collision and crushing materials and belongs to the vulnerable part, the existing method is to use surfacing to surfacing a layer of wear-resistant layer on the main body 32, the surfacing wear-resistant layer is integral, and after a long time, the local crushing is difficult to maintain, and after the wear-resistant layer is damaged, the crushing efficiency of the materials will be reduced. In order to improve the above situation, a plurality of reinforcing rings 33 are arranged side by side on the main body 32, the reinforcing ring 33 is directly sleeved on the square main body 32 and will not be affected by the rotation of the material, and the plurality of reinforcing rings 33 are clamped by the cooperation of the stop seat 34 and the upper end of the main body 32, specifically, the stop seat 34 abuts against the outermost reinforcing ring 33, and the upper end of the main body 32 abuts against the innermost reinforcing ring, so that the gap between the adjacent two reinforcing rings 33 is small, avoiding the broken slag entering between the reinforcing rings 33 during crushing, causing the reinforcing rings 33 to loosen. We use the reinforcing ring 33 to protect the main body 32, avoid the main body 32 directly colliding with the materials, when the reinforcing ring 33 is damaged, the stop seat 34 can be directly detached, and the corresponding damaged reinforcing ring 33 can be replaced, which greatly reduces the use cost of the hammer head, improves the maintenance speed, reduces the downtime, and effectively improves the production efficiency.

[0016] As Figs. 1-2As shown, the stop seat 34 comprises a screw rod 341, a stop disc 342 and a plurality of pads 343, the stop disc 342 is installed at one end of the screw rod 341, the screw rod 341 is screwed in the hollow position, and the plurality of pads 343 are installed on the lower end surface of the stop disc 342, and the pads 343 abut against the reinforcing rings 33. Specifically, during assembly, the stop disc 342 is screwed, the screw rod 341 is screwed into the hollow position, so that the distance between the pads 343 and the outermost reinforcing ring 33 is shortened, until the pads 343 abut against the reinforcing ring 33, thereby clamping the plurality of reinforcing rings 33, so that they are assembled compactly, and at the same time, a transverse bolt can be arranged on the main body 32 to lock the screw rod 341 and prevent the screw rod 341 from loosening and exiting from the hollow position.

[0017] As shown in the drawings, Figs. 1-2 As shown, the reinforcing ring 33 is provided with a sharp taper angle 331 in the rotation direction of the transmission shaft 2, when the hammer head body 3 rotates along the transmission shaft 2, it also swings around the connection with the mounting disc 1, when swinging, the sharp taper angle 331 of the reinforcing ring 33 collides with the material, the sharpness formed by the sharp taper angle 331 has sufficient strength, which can ensure the formation of a protruding crushing area, improve the crushing effect on the material, and enhance the wear resistance of the impact area of the reinforcing ring 33, and enhance the service life of the reinforcing ring 33.

[0018] As shown in the drawings, Figs. 1-2 As shown, the mounting disc 1 is provided with a sawtooth 11 on the side, which can collide with the material rebounding in the crushing cavity, thereby enhancing the crushing effect on the material.

[0019] Specifically, the number of the hammer head bodies 3 is three, which are uniformly and spacedly arranged around the central axis of the transmission shaft 2, and in other embodiments, other numbers can also be designed, as long as the hammer head bodies 3 do not interfere with each other when swinging.

[0020] The above embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as limiting the scope of the application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
