[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] Reference Figure 1 and Figure 2An embodiment of this utility model provides a mining impact crusher, including a bearing plate 1, a double-head motor 101 fixedly connected to the upper surface of the bearing plate 1, a drive cam 102 fixedly provided at the output end of the double-head motor 101, a first screen plate 103 fixedly connected to the lower surface of the bearing plate 1, a fixing block 104 fixedly connected to the outer wall of the first screen plate 103, a first spring plate 105 fixedly connected to the right outer wall of the fixing block 104, a support frame 106 fixedly connected to the upper surface of the fixing block 104, a rotating rod 107 rotatably connected to the inner wall of the drive cam 102, a connecting rod 108 rotatably connected to the inner wall of the rotating rod 107, a connecting block 109 rotatably connected to the outer wall of the connecting rod 108, a second screen plate 110 fixedly connected to the lower surface of the connecting block 109, a second spring plate 111 fixedly connected to the outer wall of the second screen plate 110, the outer wall of the second spring plate 111 fixedly connected to the outer wall of the first screen plate 103, and a crushing component 2 provided on the outer wall of the support frame 106.
[0025] Specifically, the dual-head motor 101 fixed on the support plate 1 is started to drive the drive cam 102 to rotate, causing the rotating rod 107 to rotate. The rotating rod 107 drives the connecting rod 108 to move, causing the connecting block 109 to move. The movement of the connecting block 109 causes the second screening plate 110 to shake, causing the second spring plate 111 to deform. The second spring plate 111 drives the first screening plate 103 to shake, causing the first spring plate 105 to deform. The support frame 106 is connected to the first spring plate 105 to achieve the effect of fixing the entire screening assembly to the inner wall of the outer shell 201. This assembly can automatically distinguish stones of different sizes, thereby improving product quality.
[0026] Reference Figure 1 and Figure 3 The crushing component 2 includes a shell 201, the inner wall of the shell 201 is fixedly connected to the outer wall of the support frame 106, the inner wall of the shell 201 is rotatably connected to a rotor 202, the inner wall of the shell 201 is fixedly connected to an impact plate 203, the lower surface of the shell 201 is fixedly connected to a bottom plate 204, and the upper surface of the bottom plate 204 is provided with a feeding component 3.
[0027] Specifically, the stone is fed into the outer shell 201 fixed on the base plate 204, and under the action of the rotor 202 and the impact plate 203, the stone is crushed into the required size, thereby achieving the effect of crushing operation.
[0028] Reference Figure 1 and Figure 4The feeding assembly 3 includes a fixing plate 301, the lower surface of which is fixedly connected to the upper surface of the base plate 204. A motor body 302 is fixedly connected to the upper surface of the fixing plate 301. A double-headed worm gear 303 is fixedly installed at the output end of the motor body 302. A support block 304 is rotatably connected to the outer wall of the double-headed worm gear 303, and the lower surface of the support block 304 is fixedly connected to the upper surface of the base plate 204. A worm wheel 305 is meshed with the tooth ends of the double-headed worm gear 303. A threaded rod 306 is fixedly connected to the inner wall of the worm wheel 305. The lower end of the outer wall of the threaded rod 306 is rotatably connected to the inner wall of the base plate 204, and the upper end of the threaded rod 306 is rotatably connected to the inner wall of the base plate 204. A bearing shell 307 is dynamically connected; a slider 308 is threadedly connected to the outer wall of the threaded rod 306, and the outer wall of the slider 308 is slidably connected to the inner wall of the bearing shell 307. A rotating shaft 309 is rotatably connected to the inner wall of the slider 308, and a material box 310 is fixedly connected to the outer wall of the rotating shaft 309; a half gear 311 is fixedly connected to the outer wall of the rotating shaft 309, and a rotating rack 312 is meshed with the tooth end of the half gear 311. The rear outer wall of the rotating rack 312 is fixedly connected to the outer wall of the bearing shell 307; a bracket 313 is fixedly connected to the rear outer wall of the bearing shell 307, and the lower surface of the bracket 313 is fixedly connected to the upper surface of the base plate 204.
[0029] Specifically, the motor body 302, fixed on the fixed plate 301, drives the double-headed worm gear 303 to rotate, causing the worm wheel 305 to rotate simultaneously. The worm wheel 305 drives the threaded rod 306 to rotate inside the bearing shell 307, causing the slider 308 to slide inside the bearing shell 307. The slider 308 drives the rotating shaft 309 to move, causing the material box 310 to move. The material box 310 reverses under the action of the rotating shaft 309, the half gear 311, and the rotating rack 312, thereby achieving the effect of automatic feeding. The bracket 313 can provide support for the bearing shell 307. This component can not only achieve the effect of automatic feeding, but also prevent excessive stone input from causing the crusher to jam.
[0030] Working principle: When the crusher is needed, the motor body 302 fixed on the fixed plate 301 drives the double-headed worm gear 303 to rotate, causing the worm wheel 305 to rotate. The rotation of the worm wheel 305 drives the threaded rod 306 to rotate, causing the slider 308 to slide on the inner wall of the bearing shell 307. The movement of the slider 308 drives the rotating shaft 309 to move. After reaching a certain height, the half gear 311 fixed on the rotating shaft 309 drives the loading box 310 to rotate under the action of the rotating rack 312, thereby achieving automatic feeding and saving labor costs. After feeding, the rotor 202 is started, and the crushing operation is carried out under the action of the impact plate 203. The crushed stone falls onto the first screen plate 103 through the groove opened inside the support frame 106. The double-headed motor 101 is started to drive the drive cam 102 to rotate, causing the rotating rod 107 to rotate. The rotating rod 107 rotates on the inner wall of the bearing shell 307. The connecting rod 108 and the connecting block 109 cause the second screen plate 110 to vibrate. The vibration of the second screen plate 110 causes the second spring plate 111 to deform, causing the first screen plate 103 to vibrate. The vibration of the first screen plate 103 causes the fixing block 104 to cause the first spring plate 105 to undergo elastic deformation. This component can separate stones of different sizes, separate the finished stone, and transport the larger stones out again for further processing, thereby improving product quality. This crusher not only solves the problem in the existing technology that the crushed stone is usually poured directly onto the screen and screened once, which cannot screen out small particles in large stones, resulting in the final product containing fine stone particles and causing low product quality, but also solves the problem that excessive stone is put into the crusher, causing the machine to jam, reducing its service life and production efficiency.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
