Technical Field

[0001] This utility model relates to the field of sand making machine technology, specifically to a crushing device for a sand making machine. Background Technology

[0002] A sand making machine is a mechanical device used for sand and gravel processing. It is mainly used to crush stone into fine sand, artificial sand, etc. that meet the requirements. It is widely used in industries such as construction, building materials, chemical industry, and mining. The main function of a sand making machine is to crush and shape stone through the impact and friction between materials and between materials and equipment. It can also screen materials to produce sand with uniform particle size.

[0003] According to a public announcement of a sand making machine crushing device (publication number: CN218250447U), it includes: a box body and a dust collection box disposed on the side of the box body; a feed hopper is provided at the top of the box body, a support plate is connected to the inner wall of the box body, a grinding chamber is connected to the other side of the support plate, a grinding wheel is provided inside the grinding chamber, a fourth telescopic rod is connected to the bottom of the box body, a second push plate is provided at the top of the fourth telescopic rod, and a second telescopic rod is connected to the bottom of the box body. However, in the above device, the support plate, dust collection box and feed hopper and other components cooperate with each other, making it difficult to achieve the effect of automatic material feeding during the crushing process, making it difficult to prevent material from accumulating or getting stuck at the feed inlet, and making it difficult to avoid the situation of the feed inlet being blocked. It needs to be improved. Utility Model Content

[0004] This utility model proposes a crushing device for a sand making machine, which solves the problems mentioned in the above documents.

[0005] The technical solution of this utility model is as follows: a crushing device for a sand making machine includes a support frame, a collection box is fixedly connected to the side of the support frame, a crushing box is fixedly connected to the top of the support frame, and a discharge port is fixedly connected to the top of the crushing box.

[0006] A crushing device is installed on the top of the support frame. The crushing device includes a motor, which is fixedly connected to the top of the support frame. A sprocket is fixedly connected to the output shaft of the motor. A chain is provided on the side of the sprocket. A rotating rod passes through the side of the crushing box. A chain wheel is fixedly connected to the circumferential surface of the rotating rod. A gear is fixedly connected to the circumferential surface of the rotating rod. A rotating rod is rotatably connected to the side of the crushing box. A gear disk is fixedly connected to the circumferential surface of the rotating rod. A rotating shaft passes through the side of the discharge port. A rotating gear is fixedly connected to the circumferential surface of the rotating shaft. A discharge plate is fixedly connected to the circumferential surface of the rotating shaft. A crushing roller is fixedly connected to the circumferential surface of the rotating rod.

[0007] The side of the sprocket meshes with the side of the chain, and the side of the chain meshes with the side of the chain wheel. The design of the chain and chain wheel allows the crushing roller to rotate, making the crushing more uniform.

[0008] The number of feeding plates is set to several, and they are arranged in a circumferential array on the circumferential surface of the rotating shaft. During the crushing process, the feeding plates continuously clean the feeding port by rotating, which effectively prevents the material from accumulating or getting stuck at the feeding port and avoids the situation of the feeding port being blocked.

[0009] The crushing device includes a filter structure, which includes a filter plate slidably connected to the side of a support frame. A rotating rod A is rotatably connected to the side of the crushing box. A support rod is fixedly connected to the circumferential surface of the rotating rod A. A roller is rotatably connected to the side of the support rod. A gear A is fixedly connected to the circumferential surface of the rotating rod A.

[0010] A mounting plate is fixedly connected to the side of the support frame, and a spring is fixedly connected to the top of the mounting plate. The end of the spring away from the mounting plate is fixedly connected to the bottom of the filter plate. The design of the filter plate causes it to shake continuously, preventing it from becoming clogged due to the accumulation of solid particles.

[0011] The side of gear A meshes with the side of the gear, and the side of the gear meshes with the side of the gear disk. The design of gear A and the gear causes the filter plate to vibrate continuously, which speeds up the separation process between sand and liquid, reduces the accumulation of solid particles on the filter plate, and avoids clogging.

[0012] The spring is initially in a relaxed state, and the number of crushing rollers is set to two, which are symmetrical about each other along the vertical central axis of the crushing box. The spring design allows the filter plate to automatically reset, reducing manual intervention.

[0013] The filter plate is located on the movement trajectory of the roller, and the side of the gear disk meshes with the side of the rotating gear. Frequent shaking helps to keep the filter plate clean and avoid excessive wear on the equipment due to the accumulation of deposits, thereby extending the service life of the filter plate and other components.

[0014] The number of springs is set to several, in pairs, and symmetrical to each other along the vertical central axis of the filter plate. The spring design can improve the filtration speed and efficiency, and the equipment can process more materials in the same amount of time.

[0015] The number of gears is set to two, and they are symmetrical to each other along the vertical central axis of the crushing box. The gears avoid uneven crushing caused by material accumulation, thereby improving the sand production quality.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] 1. In this utility model, the force of the motor-driven sprocket to rotate is coordinated with the rotating rod, gear disk and rotating gear in the crushing device. This achieves the effect of rotating the rotating shaft through the rotating gear, rotating the crushing roller through the rotating rod, and rotating the feeding plate through the rotating shaft. This achieves the effect of automatic feeding during the crushing process, effectively preventing the material from accumulating or getting stuck at the feeding port, and avoiding the situation of the feeding port being blocked.

[0018] 2. In this utility model, the force that drives gear A to rotate through the gear rotation works in conjunction with components such as the support rod, filter plate, and spring in the crushing device. This achieves the effect of rotating rod A to drive the support rod to rotate, which in turn drives the roller to rotate. The roller's rotation squeezes the filter plate. When the roller moves away from the filter plate, the filter plate returns to its original position due to the spring force. This continuous shaking of the filter plate accelerates the filtration speed, speeds up the separation process between sand and liquid, reduces the accumulation of solid particles on the filter plate, and avoids clogging.

Detailed Implementation

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. 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 of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1

[0028] like Figures 1-5 As shown, this embodiment proposes a crushing device for a sand making machine, including a support frame 101, a collection box 102 fixedly connected to the side of the support frame 101, a crushing box 103 fixedly connected to the top of the support frame 101, and a discharge port 104 fixedly connected to the top of the crushing box 103.

[0029] A crushing device 2 is provided on the top of the support frame 101. The crushing device 2 includes a motor 201, which is fixedly connected to the top of the support frame 101. A sprocket 202 is fixedly connected to the output shaft of the motor 201. A chain 203 is provided on the side of the sprocket 202. A rotating rod 204 passes through the side of the crushing box 103. A chain wheel 205 is fixedly connected to the circumferential surface of the rotating rod 204. A gear 206 is fixedly connected to the circumferential surface of the rotating rod 204. A rotating rod 208 is rotatably connected to the side of the crushing box 103. A gear disk 209 is fixedly connected to the circumferential surface of the rotating rod 208. A rotating shaft 210 passes through the side of the discharge port 104. A rotating gear 211 is fixedly connected to the circumferential surface of the rotating shaft 210. A discharge plate 212 is fixedly connected to the circumferential surface of the rotating shaft 210. A crushing roller 207 is fixedly connected to the circumferential surface of the rotating rod 204.

[0030] The side of the sprocket 202 meshes with the side of the chain 203, and the side of the chain 203 meshes with the side of the chain wheel 205. The design of the chain 203 and the chain wheel 205 allows the crushing roller 207 to rotate, making the crushing more uniform.

[0031] The number of feeding plates 212 is set to several, and they are arranged in a circumferential array on the circumferential surface of the rotating shaft 210. During the crushing process, the feeding plates 212 continuously clean the feeding port 104 by rotating, which effectively prevents the material from accumulating or getting stuck at the feeding port 104 and avoids the situation of the feeding port 104 being blocked.

[0032] In this embodiment, the application uses a motor 201 to drive a sprocket 202 to rotate, which in turn drives a chain 203 to rotate. The chain 203 then drives a chain wheel 205 to rotate, which in turn drives a rotating rod 204 to rotate. The rotating rod 204 then drives a gear 206 to rotate, which in turn drives a gear disc 209 to rotate. The gear disc 209 then drives a rotating gear 211 to rotate, which in turn drives a rotating shaft 210 to rotate. The rotating rod 204 then drives a crushing roller 207 to rotate, and the rotating shaft 210 then drives a feeding plate 212 to rotate. This achieves automatic feeding during the crushing process, and the rotation of the feeding plate 212 helps prevent blockage of the feeding port 104.

[0033] Example 2

[0034] like Figures 1-5 As shown, based on the same concept as Embodiment 1 above, a second embodiment is also proposed. The crushing device 2 includes a filter structure, which includes a filter plate 217. The filter plate 217 is slidably connected to the side of the support frame 101. A rotating rod A213 is rotatably connected to the side of the crushing box 103. A support rod 215 is fixedly connected to the circumferential surface of the rotating rod A213. A roller 216 is rotatably connected to the side of the support rod 215. A gear A214 is fixedly connected to the circumferential surface of the rotating rod A213.

[0035] A mounting plate 219 is fixedly connected to the side of the support frame 101. A spring 218 is fixedly connected to the top of the mounting plate 219. The end of the spring 218 away from the mounting plate 219 is fixedly connected to the bottom of the filter plate 217. The design of the filter plate 217 causes the filter plate 217 to shake continuously, so that the filter plate 217 will not be clogged due to the accumulation of solid particles.

[0036] The side of gear A214 meshes with the side of gear 206, and the side of gear 206 meshes with the side of gear disk 209. The design of gears A214 and 206 causes the filter plate 217 to vibrate continuously, which accelerates the separation process between sand and liquid, reduces the accumulation of solid particles on the filter plate 217, and avoids clogging.

[0037] The spring 218 is initially in a relaxed state. The number of crushing rollers 207 is set to two, and they are symmetrical about each other along the vertical central axis of the crushing box 103. The design of the spring 218 can automatically reset the filter plate 217, reducing manual intervention.

[0038] The filter plate 217 is located on the movement trajectory of the roller 216. The side of the gear disk 209 meshes with the side of the rotating gear 211. Frequent shaking helps to keep the filter plate 217 clean and avoids excessive wear on the equipment due to the accumulation of deposits, thereby extending the service life of the filter plate 217 and other components.

[0039] The number of springs 218 is set to several, in pairs, and symmetrical to each other along the vertical central axis of the filter plate 217. The design of springs 218 can improve the filtration speed and efficiency, and the equipment can process more materials in the same amount of time.

[0040] The number of gears 206 is set to two, and they are symmetrical to each other along the vertical central axis of the crushing box 103. The gears 206 avoid uneven crushing caused by material accumulation, thereby improving the sand making quality.

[0041] In this embodiment, the rotation of gear 206 drives gear A214 to rotate, which in turn drives rotating rod A213 to rotate. The rotation of rotating rod A213 drives supporting rod 215 to rotate, which in turn drives roller 216 to rotate. The rotation of roller 216 compresses filter plate 217. When roller 216 moves away from filter plate 217, filter plate 217 returns to its original position due to the elastic force of spring 218, thus achieving the effect of continuous shaking of filter plate 217 to accelerate filtration speed.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
