Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of engineering machinery, in particular to a crusher plate hammer structure. Background Art
[0002] A crusher is a device that utilizes the plate hammers on a high-speed rotating rotor (or rotor body) to produce high-speed impact and crush the materials fed into the crushing chamber. During the crushing process, the plate hammers will be worn or curled due to the combined effects of impact and extrusion of high-hardness materials. The plate hammer is the most important working component of the impact crusher. The plate hammer is an easily worn part. The existing plate hammer structure has only two working angles for crushing materials, while the other two angles of the plate hammer cannot be used. After the two working angles of the plate hammer are worn out, they can only be removed and replaced with new plate hammers, and the old plate hammers are scrapped, resulting in increased plate hammer loss costs and reduced material utilization efficiency of the plate hammer. Therefore, the utility model provides a crusher plate hammer structure to solve the problems raised in the above background technology. Utility Model Content
[0003] In view of the above problems, the utility model provides a crusher plate hammer structure, which can reduce the plate hammer loss cost and improve the material utilization efficiency of the plate hammer.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] A crusher plate hammer structure comprises: a rotor body and a plate hammer, wherein the plate hammer is fixedly connected inside the rotor body, slots are arranged in linear arrays on both sides of the plate hammer, and positioning bars are fixedly connected inside the slots.
[0006] As a further improvement of the above technical solution, the positioning strips are arranged at intervals on the installation clamping surface of the blow hammer.
[0007] As a further improvement of the above technical solution, the positioning bar adopts a trapezoidal structure.
[0008] As a further improvement of the above technical solution, a circumferential array of mounting grooves is provided on the side surface of the rotor body.
[0009] As a further improvement of the above technical solution, a clamping plate is fixedly connected in the mounting groove of the rotor body.
[0010] As a further improvement of the above technical solution, the four corners of the plate hammer are working angles.
[0011] As a further improvement of the above technical solution, the plate hammer is installed and fixed between the rotor body and the clamping plate.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] By adopting the plate hammer and the positioning plate, the plate hammer is clamped in the mounting groove of the rotor body through the positioning plate, and then the clamping plate is used to press against the plate hammer to fix it. After that, the rotor body drives the plate hammer to crush the material by changing back and forth at angles a, b, c and d. When the four corners are worn to the limit, the old plate hammer is removed from the rotor body and replaced with a new one to continue working, which can reduce the plate hammer loss cost and improve the material utilization efficiency of the plate hammer.

[0021] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model is described in detail below in conjunction with the embodiments. The description in this section is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model. Example
[0022] refer to Figure 1-Figure 6 A crusher hammer structure includes: a rotor body 1 and a hammer 2. The hammer 2 is fixedly connected inside the rotor body 1. Linear arrays of notches 6 are provided on both sides of the hammer 2. Positioning bars 3 are fixedly connected inside the notches 6.
[0023] As a preferred embodiment of the above embodiment, the positioning strips 3 are arranged at intervals on the mounting clamping surface of the blow hammer 2 .
[0024] As a preferred embodiment of the above embodiment, the positioning bar 3 adopts a trapezoidal structure.
[0025] As a preferred embodiment of the above embodiment, mounting grooves 4 are arranged in a circumferential array on the side surface of the rotor body 1 .
[0026] As a preferred embodiment of the above embodiment, a clamping plate 5 is fixedly connected in the mounting groove 4 of the rotor body 1 .
[0027] As a preferred embodiment of the above embodiment, the four corners of the plate hammer 2 are working angles.
[0028] As a preferred embodiment of the above embodiment, the hammer 2 is installed and fixed between the rotor body 1 and the clamping plate 5 .
[0029] The specific working principle of this utility model:
[0030] During use, the plate hammer 2 is first installed between the mounting groove 4 and the clamping plate 5 in the rotor body 1 through the positioning block, and then the external driving motor is started to drive the rotor body 1 to rotate, so that the rotor body 1 drives the plate hammer 2 to rotate, and the four corners of the plate hammer 2 are working angles, namely angle a, angle b, angle c, and angle d. In the process of the rotor body 1 driving the plate hammer 2 to rotate, the plate hammer 2 first starts to grind the material through angle a, so that the material begins to be crushed, and the angle a of the plate hammer 2 is gradually worn away by it, and the fillet of angle a also begins to increase. When angle a is worn to the limit, First, turn off the external drive motor, then manually flip the plate hammer 2 over to change the wear angle of the plate hammer 2 from angle a to angle d, then start the external drive motor again, so that the drive motor starts to drive the rotor body 1 to rotate, and the plate hammer 2 continues to crush the material. If the angle d of the plate hammer 2 is also worn to the limit, just rotate the plate hammer 2 for adjustment, so that the plate hammer 2 uses the angles b and c to crush the material in turn. When the wear of angles b and c reaches the limit, manually remove the plate hammer 2 and replace it to crush the material. This can reduce the loss cost of the plate hammer 2 and improve the use efficiency of the plate hammer 2.
