Description

Technical Field

[0001] The utility model relates to the technical field of hammer type pulverizers, in particular to a hammer for a material pulverizer. Background Art

[0002] The hammer mill is the most widely used type of mill. The feed enters the grinding chamber from the feeding mechanism and flies to the tooth plate under the impact of the high-speed rotating hammers. After colliding with the tooth plate and rebounding, it is hit by the hammers again. At the same time, the feed is subjected to strong friction between the screen surface and the hammers. Under the repeated impact, collision and friction, the feed is gradually crushed.

[0003] The hammer is a component that directly collides with the material, which causes severe wear and tear of the hammer and requires frequent replacement. Each replacement requires the hammer to be removed together with the fixed shaft, and then replaced with a new hammer, which means that the hammer on a fixed shaft will be removed and installed. It takes a lot of time, and production needs to be stopped during this period, which seriously affects efficiency and production progress;

[0004] When the hammer is in use, the area of ​​one side of the hammer that strikes the material is small, and during the striking process, some of the material will collide with the hammer shaft, causing wear of the hammer shaft, and in this process, this part of the material will not be completely crushed. Therefore, a hammer for a material crusher is proposed to solve the above-mentioned problems. Utility Model Content

[0005] Based on the above description, the utility model provides a hammer for a material crusher to solve the problems that the existing hammer takes a long time to replace and the hammer shaft is prone to wear.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the hammer seat comprises a main seat body, and an outer surface of the main seat body is provided with an axial hole and a mounting hole.

[0009] Furthermore, a placement groove is provided on the upper surface of the main seat body, and the bottom wall of the placement groove is an arc-shaped toothed bottom surface.

[0010] Furthermore, the hammer plate includes a hammer main board, and the lower surface of the hammer main board is provided with a toothed arc-shaped lower surface, and the toothed arc-shaped lower surface is in contact with the arc-shaped toothed bottom surface.

[0011] Furthermore, a connection hole and a positioning slot are provided on the surface of the hammer mainboard, and a positioning groove and a first positioning hole are provided at the positioning slot.

[0012] Furthermore, the positioning groove and the first positioning hole are connected to each other, and the first positioning hole passes through the hammer main board.

[0013] Furthermore, the impact block includes a mounting bar, and a transverse plate is provided on one side of the mounting bar close to the hammer plate.

[0014] Furthermore, the transverse plate is arranged inside the positioning slot, and a second positioning hole is arranged on the surface of the transverse plate, and the second positioning hole corresponds to the first positioning hole.

[0015] Furthermore, the collision block includes a collision block body, both ends of the collision block body are provided with threaded holes, the upper and lower sides of the collision block body are arc-shaped surfaces, and the collision block extends to the inside of the positioning groove.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0017] 1. The utility model provides components such as a hammer seat, a hammer plate and a striking block, and the hammer plate and the hammer seat cooperate with each other, so that the hammer can be directly disassembled and replaced after being worn, and the striking block and the hammer plate can also be disassembled and replaced separately, thereby making the replacement of a single hammer plate more efficient and less time-consuming;

[0018] 2. By setting the collision blocks, the air flow velocity between the collision blocks is increased, thereby generating low pressure here, achieving the effect of directional air flow, and thus making the material bound on the path of the hammer movement as much as possible to avoid the material and the hammer shaft colliding with each other.

[0032] Embodiment 1

[0033] See also Figure 1-Figure 3 , a hammer piece for a material crusher, comprising:

[0034] A hammer seat 1, the hammer seat 1 comprises a main seat body 11, the outer surface of the main seat body 11 is provided with an axial hole 12 and a mounting hole 14, the upper surface of the main seat body 11 is provided with a placement groove 13, and the bottom wall of the placement groove 13 is an arc-shaped toothed bottom surface;

[0035] Based on the above, the hammer seat 1 plays a role in connecting the hammer shaft and the hammer plate 2. When the hammer plate 2 is placed inside the placement groove 13, the hammer plate 2 and the hammer seat 1 are connected to each other through screws and nuts.

[0036] like Figure 1 , Figure 2 and Figure 4 As shown, a hammer plate 2 is arranged inside the hammer seat 1 by screws and nuts, and the hammer plate 2 includes a hammer main board 21, and the lower surface of the hammer main board 21 is provided with a toothed arcuate lower surface 22, and the toothed arcuate lower surface 22 is in contact with the arcuate toothed bottom surface, and the surface of the hammer main board 21 is provided with a connecting hole 23 and a positioning card slot 24, and the positioning card slot 24 is provided with a positioning groove 25 and a first positioning hole 26, and the positioning groove 25 and the first positioning hole 26 are connected to each other, and the first positioning hole 26 passes through the hammer main board 21;

[0037] Based on the above, the hammer plate 2 plays the role of connecting the hammer seat 1 and the impact block 3, and the hammer plate 2 plays the role of bearing the impact force, wherein the toothed arc-shaped lower surface 22 cooperates with the arc-shaped toothed bottom surface, so that after the hammer plate 2 is impacted, there are enough force points between the hammer plate 2 and the hammer seat 1, avoiding the situation where the hammer seat 1 is damaged due to too single force point, and the setting of the positioning groove 25 and the positioning slot 24 plays the role of positioning the collision block 4 and the impact block 3.

[0038] like Figure 1 and Figure 5 As shown, the impact block 3 is arranged on both sides of the hammer plate 2, and the impact block 3 includes a mounting strip 31, and a horizontal plate 32 is arranged on one side of the mounting strip 31 close to the hammer plate 2, and the horizontal plate 32 is arranged inside the positioning slot 24, and a second positioning hole 33 is arranged on the surface of the horizontal plate 32, and the second positioning hole 33 corresponds to the first positioning hole 26;

[0039] Based on the above, the impact block 3 directly collides with the material, thereby preventing the hammer plate 2 from being excessively worn, extending the service life of the hammer plate 2, and obtaining different use effects by installing different impact blocks 3.

[0040] like Figure 1 , Figure 6 and Figure 7As shown, the collision block 4 is arranged between the hammer plates 2 by screws, and the collision block 4 includes a collision block body 41, both ends of the collision block body 41 are provided with threaded holes 42, the upper and lower sides of the collision block body 41 are arc-shaped surfaces, and the collision block 4 extends to the inside of the positioning groove 25;

[0041] Based on the above, the collision block 4 plays a role in increasing the contact area between the hammer and the material on the one hand, and in limiting the movement trajectory of the material on the other hand, that is, when the hammer moves, the movement direction of the airflow is as follows: Figure 7 As shown, when flowing from A to B, the space in the middle of the path is smaller, so the flow velocity increases when the air flows through, and the air pressure is small at the location with fast flow velocity, that is, suction is generated. When the material hits and moves toward the hammer shaft, the material hitting the hammer shaft can be reduced as much as possible under the action of the suction, thereby protecting the hammer shaft.

[0042] Embodiment 2

[0043] Based on the first embodiment, Figure 8 As shown, after the collision block 4 is removed, the collision block 3 is connected to the hammer plate 2 by the action of screws and nuts. At this time, the hammer is closer to a traditional hammer, and the material is crushed only by the collision between the collision block 3 and the material. The hammer is provided with the collision block 3 and the hammer plate 2, so that after the hammer is seriously damaged, it is convenient for targeted replacement, which reduces the difficulty of replacement and shortens the time.

[0044] When the above embodiments are actually used, the shape of the hammer can be changed according to actual needs, which are the shapes of the above two embodiments. The second embodiment is closer to the existing hammer, and its crushing effect is consistent with the existing hammer. Compared with the existing hammer, it is easier to replace the impact block 3 and the hammer plate 2, achieving the effect of short replacement time.

[0045] The hammer of the first embodiment is provided with a collision block 4, which increases the contact area with the material to obtain a better crushing effect, and Figure 7 As shown, by reducing the space where the air flows and compressing the air flow, the air flow velocity is increased, the pressure at that location is reduced, and suction is generated to prevent the material from breaking through the area where the hammer moves and hitting the hammer shaft, thereby protecting the hammer shaft.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
