Description

Technical Field

[0001] This utility model relates to the field of crusher hammer technology, and in particular to a crusher hammer. Background Technology

[0002] Hammer crushers are widely used crushing machinery in industries such as cement, ceramics, mining, and power. They are mainly suitable for crushing medium-hard materials such as limestone, slag, coke, and coal. Hammer crushers primarily rely on impact energy to complete the crushing operation. They can directly crush materials with a maximum particle size of 600-1800 mm to below 20-25 mm. When the crusher is working, the motor drives the rotor to rotate at high speed. The material enters the crushing chamber evenly, and the high-speed rotating hammers on the rotor impact, shear, and tear the material, causing it to break.

[0003] Traditional crusher hammers have some drawbacks. When the crusher is working, the connection between the hammer and the drum mainly bears shear stress. When the hammer strikes the material, it causes the hammer and the material to be subjected to a large impact force, which can easily lead to breakage. Because this part is under high stress for a long time, the hammer becomes the most vulnerable part of the whole machine. Frequent replacement not only increases maintenance costs, but also seriously affects production efficiency. Utility Model Content

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figure 1-5 As shown, a crusher hammer includes a connecting part 1. A hammer control mechanism 2 is provided at the lower end of the connecting part 1. The hammer control mechanism 2 includes a mounting frame 21 fixedly connected to the lower end of the connecting part 1. A hammer body 22 is movably connected to the inner side of the mounting frame 21. An control groove 23 is provided at the front end of the mounting frame 21. A control plate 24 is movably connected to the inner side of the control groove 23. A rotating shaft 25 is fixedly connected to the inner side of the control plate 24. A limiting groove 26 is provided at the front end of the rotating shaft 25. A limiting hole 27 is provided at the front end of the control plate 24. A positioning frame 28 is fixedly connected to the inner wall of the control groove 23. A fastening bolt 29 is threadedly connected to the inside of the positioning frame 28. A limiting rod 210 is slidably connected to the inner side of the limiting groove 26. A fixing frame 211 is fixedly connected to the outer side of the limiting rod 210 near the front side of the limiting groove 26.

[0022] In this embodiment, a retaining ring 212 is fixedly connected to the outer side of the front end of the mounting bracket 21 near the regulating groove 23. An internally threaded cap 213 is threadedly connected to the outer side of the retaining ring 212. The mounting bracket 21 is U-shaped, and the hammer body 22 is elliptical. A rotating shaft 25 passes through the interior of the mounting bracket 21 and is movably connected to the mounting bracket 21. The rotating shaft 25 extends into the interior of the hammer body 22 and is fixedly connected to the hammer body 22. A limiting groove 26 is also present. The shape is arc-shaped. The center lines of the hammer body 22, the regulating groove 23, the control plate 24, the rotating shaft 25, and the limiting groove 26 are on the same straight line. The positioning frame 28 is located outside the control plate 24. The fastening bolt 29 extends into the inner side of the limiting hole 27. The fastening bolt 29 and the limiting hole 27 are threadedly connected. The upper end of the fixing frame 211 is fixedly connected to the top of the inner side of the regulating groove 23. The center lines of the rotating shaft 25, the cover ring 212, and the internal thread cover 213 are on the same straight line.

[0023] Specifically, if prolonged use leads to severe wear on the lower end of the hammer body 22, the worker can loosen the fastening bolt 29, causing it to disengage from the limiting hole 27 and the positioning bracket 28. Then, the hammer body 22 is rotated, causing the hammer body 22 to drive the rotating shaft 25 to rotate. This, in turn, causes the rotating shaft 25 to drive the control plate 24 to rotate within the positioning bracket 28. The rotating shaft 25 also causes the limiting groove 26 to slide along the limiting rod 210. Limited by the space of the limiting groove 26, the limiting rod 210 can impede the rotation of the rotating shaft 25, allowing the rotating shaft 25 to rotate within a specified range. This allows the lower end of the hammer body 22 to be rotated into the mounting bracket 21, and the upper end of the hammer body 22 to rotate. By unscrewing the fastening bolt 29 and rotating the hammer body 22, the rotation shaft 25 drives the control plate 24 to rotate, and the upper end of the hammer body 22 is rotated downwards. This allows the upper end of the hammer body 22 to contact the material, thereby changing the position of the upper and lower ends of the hammer body 22 and making full use of both ends of the hammer body 22, increasing the number of times the hammer body 22 can be used.

[0024] In this embodiment, a bearing body 3 is installed at the upper end of the connecting part 1, and a shaft hole 4 is opened at the front end of the bearing body 3.

[0025] Specifically, the worker first places the shaft seat body 3 in the designated position on the crusher, and then uses the shaft hole 4 to install the shaft seat body 3 on the crusher. Then the crusher is started, so that the crusher uses the shaft seat body 3 to drive the hammer body 22 to rotate, so that the hammer body 22 hits the material and can crush the material.

[0026] Working principle:

[0027] In use, the worker first places the shaft seat body 3 in the designated position on the crusher, and then installs the shaft seat body 3 on the crusher using the shaft hole 4. The crusher is then started, causing the shaft seat body 3 to drive the hammer body 22 to rotate, thus causing the hammer body 22 to strike the material and crush it. However, with prolonged use, the lower end of the hammer body 22 will wear severely. At this point, the worker unscrews the inner thread cover 213, exposing the regulating groove 23 directly. Then, the worker unscrews the fastening bolt 29, disengaging it from the limiting hole 27 and the positioning frame 28. The hammer body 22 is then rotated, causing the hammer body 22 to drive the rotating shaft 25 to rotate. The rotating shaft 25 then drives the control plate 24 to rotate inside the positioning frame 28, and the rotating shaft 25 causes the limiting groove 26 to slide along the limiting rod 210. Limited by the space of the limiting groove 26, the limiting rod 210 can impede the rotation of the rotating shaft 25 and prevent the rotation from reaching the target area. Rotating the rotating shaft 25 within a specified range allows the lower end of the hammer body 22 to rotate into the mounting bracket 21 and the upper end of the hammer body 22 to rotate downwards, thus enabling the upper end of the hammer body 22 to contact the material. Then, tightening the fastening bolt 29 into the positioning bracket 28 and the limiting hole 27 limits the rotation of the control plate 24 and the position of the hammer body 22. Finally, tightening the internal threaded cover 213 onto the outside of the cover ring 212 completes the position exchange of the upper and lower ends of the hammer body 22. By unscrewing the fastening bolt 29 and rotating the hammer body 22, the rotating shaft 25 drives the control plate 24 to rotate, and the upper end of the hammer body 22 to rotate downwards, making it easier for the upper end of the hammer body 22 to contact the material. This allows for the exchange of the upper and lower ends of the hammer body 22 and makes full use of both ends, increasing the number of times the hammer body 22 can be used.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
