[0002] The impact crusher, also known as the impact crusher, can process materials with a side length of 100 to 500 mm or less. It has a maximum compressive strength of 350 MPa, a large crushing ratio, and the material is in cubic particles after crushing. It is widely used in building materials, ore crushing, railways, highways, energy, transportation, energy, cement, mining, chemical industry and other industries for medium and fine crushing of materials.

[0003] The existing plate hammer device for impact crusher has the main problem that the plate hammer cannot be extended during use, which makes it impossible to adjust the length of the plate hammer, and further leads to the inability to adjust the size of the crushed material. Secondly, the existing plate hammer device for impact crusher also has the problem of not being able to quickly disassemble and assemble the plate hammer during use, which makes the plate hammer very easy to be damaged after a long period of crushing, thereby affecting the subsequent crushing work. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a plate hammer for an impact crusher, which has the advantages of adjustable plate hammer length and easy replacement, and solves the problems raised by the above-mentioned background technology.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The plate hammer of the impact crusher is used in conjunction with a limit block and a pull plate, and utilizes the fixed connection between the pull plate and the T-shaped frame, as well as the sliding connection between the pull plate and the inner wall of the slide groove, and then pulls the pull plate downward, so that the pull plate drives the T-shaped frame to press the spring 2 downward on the inner wall of the T-shaped groove. At this time, the T-shaped frame shrinks to the bottom of the inner wall of the T-shaped groove, causing the limit block to detach from the circular hole at the bottom of the slider, and then pulls the extended plate hammer, so that the slider slides on the inner wall of the strip groove, and then the extended plate hammer can be adjusted to three levels, thereby achieving the purpose of extending the plate hammer body.

[0013] 2. The plate hammer of the impact crusher is used in conjunction with the clamping block and the clamping slot. By simultaneously pulling the extrusion frames on both sides of the plate hammer body inward, the extrusion spring of the extrusion frame is deformed and contracted. At this time, the extrusion frame approaches the groove on the inner wall of the U-shaped frame, and at the same time drives several clamping blocks to simultaneously detach from the inner walls of several clamping slots. At this time, the plate hammer body can be taken out, thereby achieving the purpose of quickly replacing the plate hammer body. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In the above structure, the extended plate hammer 15 can be fixed and limited by the setting of the limit block 13, so that the extended plate hammer 15 has an adjustable capability.

[0023] In a preferred embodiment, a circular hole is formed at the bottom of the sliding block 9, and the limiting block 13 is slidably connected to the circular hole.

[0024] In the above structure, the limit block 13 is connected to the circular hole at the bottom of the slider 9 through sliding, and then the pull plate 16 is used to pull down the T-shaped frame 11, so that the T-shaped frame 11 squeezes the spring 12 to deform and shrink. At this time, the limit block 13 is separated from the inner wall of the slider 9, so that it can slide on the inner wall of the strip groove 8, which is convenient for adjusting the length of the extended plate hammer 15.

[0025] In a preferred embodiment, the T-shaped frame 11 is slidably connected to the inner wall of the T-shaped slot 10 , and a pull plate 16 is fixedly installed on the outer side of the T-shaped frame 11 .

[0026] In the above structure, by setting the pull plate 16 and then pulling the pull plate 16 down, the pull plate 16 can drive the T-shaped frame 11 to press the spring 2 12 downward on the inner wall of the T-shaped groove 10, and then drive the limit block 13 to be stored until the inner wall of the T-shaped groove 10 is flush with the bottom of the inner wall of the strip groove 8. At this time, the slider 9 can slide smoothly on the inner wall of the strip groove 8.

[0027] In a preferred embodiment, the number of the limiting blocks 13 is three, and the sliding block 9 is slidably connected to the inner wall of the strip groove 8 .

[0028] In the above structure, by providing the three limit blocks 13, the extended plate hammer 15 can be adjusted and extended in three levels.

[0029] In a preferred embodiment, the number of the card slots 3 and the card blocks 7 are both multiple, and the card blocks 7 are slidably connected to the inner wall of the card slots 3 .

[0030] In the above structure, by providing a plurality of clamping grooves 3 and clamping blocks 7 , the plate hammer body 14 can be stably clamped on the inner wall of the square groove 2 at the outer edge of the rotary disk 1 .

[0031] In a preferred embodiment, a slide groove is provided on the outer side of the hammer body 14 and penetrates the inner wall of the T-shaped groove 10 , and the pull plate 16 is fixedly installed on the outer side of the T-shaped frame 11 and is slidably connected to the inner wall of the slide groove.

[0032] In the above structure, through the setting of the sliding groove, the pull plate 16 can smoothly drive the T-shaped frame 11 to slide downward and squeeze the second spring 12, thereby smoothly driving the limit block 13 to be stored in the bottom of the inner wall of the T-shaped groove 10.

[0033] Working principle: When the device is needed, first, the extrusion frames 6 on both sides of the plate hammer body 14 are pulled inward at the same time, so that the extrusion frames 6 squeeze the spring 15 to deform and shrink. At this time, the extrusion frame 6 approaches the groove on the inner wall of the U-shaped frame 4, and at the same time drives a plurality of card blocks 7 to simultaneously disengage from the inner walls of a plurality of card slots 3. At this time, the plate hammer body 14 can be taken out, thereby achieving the purpose of quickly replacing the plate hammer body 14. Secondly, when the plate hammer 15 needs to be extended or adjusted, it is only necessary to use the fixed connection between the pull plate 16 and the T-shaped frame 11. The pull plate 16 is connected to the sliding connection with the inner wall of the slide groove, and then when the pull plate 16 is pulled downward, the pull plate 16 drives the T-shaped frame 11 to squeeze the spring 2 12 downward on the inner wall of the T-shaped groove 10. At this time, the T-shaped frame 11 shrinks to the bottom of the inner wall of the T-shaped groove 10, thereby causing the limit block 13 to disengage from the circular hole at the bottom of the slider 9, and then the extended plate hammer 15 is pulled to make the slider 9 slide on the inner wall of the strip groove 8, and then the extended plate hammer 15 can be adjusted to three levels, thereby achieving the purpose of extending the plate hammer body 14.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
