Description

Technical Field

[0001] The utility model relates to the field of crushing devices, in particular to a crushing device with a material guiding and buffering structure. Background Art

[0002] A crusher, also known as a stone crusher, is a crushing machine used in the processing of metal and non-metallic ores, which can crush the mined raw ore into small particles by squeezing and bending. During the feeding process of the crusher, the raw ore will hit the inner wall of the feed port, which is easy to cause damage to the feed port. In the prior art, a Chinese utility model patent with a public document number of CN209663462U discloses a feed hopper for a mine stone crusher. The utility model feed hopper consists of a hopper shell and a hopper liner, and the hopper liner can be detachably installed on the inner side wall of the hopper shell. When the hopper liner is worn, only the hopper liner needs to be replaced, and there is no need to replace the entire feed hopper, which not only avoids waste of resources, but also reduces the use cost of the feed hopper.

[0003] However, in actual use, since there are no buffer devices on the first guide plate and the second guide plate, they are easily damaged quickly after being hit by the original ore, and the angles of the first guide plate and the second guide plate are not easy to change. The crushed stone is prone to stagnation when hitting the first guide plate and the second guide plate, causing feed blockage, so improvement is needed. Utility Model Content

The second positioning rod 311 is fixedly connected to the screw holes of the first movable plate 307 and the second movable plate 310 by threads, the first positioning rod 308 and the second positioning rod 311 are located in the limiting groove 304, and the material guide component 3 also includes a spring 309. The first positioning rod 308 and the second positioning rod 311 are located at the outer position of the material guide box 301. The spring 309 is movably installed in the storage tube 303 and is located between the first movable plate 307 and the second movable plate 310. The crushed stone collides with the buffer plate 302 in the material guide box 301, causing the buffer plate 302 to move downward, and the movable The movable rod 312 pushes the second movable plate 310 downward, and the second movable plate 310 compresses the spring 309. Part of the impact force is stored by compressing the spring 309, thereby providing buffer protection for the buffer plate 302 and extending the service life of the buffer plate 302. After the gravel is intercepted by the buffer plate 302, it slides downward from the inclined buffer plate 302. As the gravel on the buffer plate 302 slides out, the compressed spring 309 resumes its expansion, thereby pushing the buffer plate 302 in the opposite direction, causing the buffer plate 302 to form a reciprocating vibration, so that the gravel on the buffer plate 302 is not easy to stagnate, and the discharge is smoother.

[0023] like Figure 2 , Figure 3 and Figure 4As shown, the fixed sleeve 317 is fixedly connected to the buffer plate 302, the clamping block 316 is fixedly connected to the connecting block 314, the clamping block 316 and the fixed sleeve 317 are movably installed, one end of the movable rod 312 is movably installed with the connecting block 314, and the other end of the movable rod 312 is fixedly connected with the second movable plate 310, the first movable plate 307 and the second movable plate 310 are movably installed in the storage tube 303, and the material guide component 3 also includes a limiting plate 313 and a rotating hole 315, the rotating hole 315 is opened on the connecting block 314, and one end of the movable rod 312 is movably installed with the connecting block 314. The end passes through the rotating hole 315 and is fixedly connected with the limit plate 313. The material guiding component 3 also includes a slot 318, and the slot 318 is opened in the fixed sleeve 317. The block 316 is movably installed in the slot 318 of the fixed sleeve 317. The No. 2 positioning rod 311 is screwed out, and the No. 2 movable plate 310 and the movable rod 312 are convenient to be moved out of the storage tube 303. Then the block 316 is moved out of the slot 318 of the fixed sleeve 317 in turn, so that the buffer plate 302 and the movable rod 312 are separated from each other, so that the buffer plate 302 is easy to replace and more convenient to use.

[0024] It should be noted that the utility model is a crushing device with a material guide buffer structure. Crushed stones fall from above and enter the material guide box 301, colliding with the buffer plate 302 in the material guide box 301, causing the buffer plate 302 to move downward, and the fixed sleeve 317 and the connecting block 314 on the buffer plate 302 move downward synchronously, so that the movable rod 312 pushes the second movable plate 310 downward, and the second movable plate 310 moves in the storage tube 303. The second movable plate 310 compresses the spring 309, and stores part of the impact force by compressing the spring 309, thereby buffering the buffer plate 302, better protecting the buffer plate 302, and extending the buffer The service life of the punch plate 302 is extended. After the crushed stone is intercepted by the buffer plate 302, it slides downward from the inclined buffer plate 302. As the crushed stone slides on the buffer plate 302, the compressed spring 309 is restored to open, thereby pushing the buffer plate 302 in the opposite direction, causing the buffer plate 302 to form a reciprocating vibration. The crushed stone on the buffer plate 302 is not easy to stagnate, and the discharge is smoother. Four movable rods 312 are arranged on the back of the buffer plate 302, which are divided into two groups, each with two. When the angle of the buffer plate 302 needs to be adjusted, the No. 1 positioning rod 308 in the corresponding storage tube 303 is screwed out, and then the corresponding bolt 306 is turned so that one The first movable plate 307 moves in the receiving tube 303, thereby pushing the buffer plate 302 outward so that the angle of the buffer plate 302 can be adjusted. When the first movable plate 307 moves to a suitable position, the first positioning rod 308 is screwed into the screw hole corresponding to the first movable plate 307. The first positioning rod 308 is located in the limiting groove 304, so that the first movable plate 307 cannot continue to rotate, and the bolt 306 cannot rotate, thereby positioning the first movable plate 307, so that the inclination angle of the buffer plate 302 is easy to adjust and more convenient to use. The second movable plate 310 is in the limiting groove 304 through the second positioning rod 311 thereon. The second movable plate 310 and the movable rod 312 are easily moved out of the storage tube 303. Then, the block 316 is moved out of the slot 318 of the fixing sleeve 317 in sequence, so that the buffer plate 302 and the movable rod 312 are separated from each other, so that the buffer plate 302 is easy to replace. After the second movable plate 310 is moved out, the spring 309 in the storage tube 303 can be easily pushed out by screwing the bolt 306, so that the spring 309, the movable rod 312 and other structures are easy to replace, making maintenance more convenient.
