DETAILED DESCRIPTION

[0028] The technical solution of the present invention is further described below in conjunction with the accompanying drawings. Example 1

[0029] A dust-reducing stone crusher for a stone field, such as Figure 1-5 As shown, it includes a supporting chassis 1, a working bin 2, a crushing bin 3, a driving motor 4, a crushing roller 5 and a feeding hopper 6; the supporting chassis 1 is fixedly connected to the working bin 2; the working bin 2 is fixedly connected to the crushing bin 3, and the crushing bin 3 is located inside the working bin 2; the crushing bin 3 is rotatably connected to two crushing rollers 5, and the crushing rollers 5 are rotatably connected to the working bin 2; the working bin 2 is fixedly connected to two driving motors 4, and the output shaft of the driving motor 4 is fixedly connected to the crushing rollers 5; the crushing bin 3 is connected to the feeding hopper 6, and the feeding hopper 6 passes through the working bin 2;

[0030] It also includes a rotating component, a rotating ring 7, a shovel plate 8, a screen 9, a conveyor belt 10 and a dust removal component; a screening net 2a is arranged at the bottom of the working bin 2; the working bin 2 is connected to the rotating component; the rotating component is connected to two rotating rings 7, and the rotating rings 7 are rotatably connected to the working bin 2, and the rotating component is used to drive the rotating rings 7 to rotate; the two rotating rings 7 are jointly fixed with four shovel plates 8 in a ring array, and the shovel plates 8 are in contact with the inner wall of the working bin 2; each shovel plate 8 is fixed with a screen 9; the supporting base frame 1 is fixed with a conveyor belt 10, and the conveyor belt 10 is located below the screening net 2a; the working bin 2 is connected to the dust removal component.

[0031] It also includes a rotating rod 111, a ring gear 112, a linkage gear 113, a lever 114 and a scraper 115; the working chamber 2 is fixedly connected to two ring gears 112; each shovel plate 8 is rotatably connected to a rotating rod 111; each rotating rod 111 is fixedly connected to a linkage gear 113 on the front and rear sides, and the linkage gear 113 is meshed with the ring gear 112; each rotating rod 111 is fixedly connected to a plurality of levers 114; each lever 114 is fixedly connected to a scraper 115.

[0032] The crushing chamber 3 also includes an arc-shaped plate 117 ; an arc-shaped plate 117 is fixedly connected to the left and right sides of the crushing chamber 3 , and the arc-shaped plate 117 is in contact with the shovel plate 8 .

[0033] The rotating assembly includes a rotating motor 101, a fixed gear 102 and a gear ring 103; the supporting frame 1 is fixedly connected to the rotating motor 101; the output shaft of the rotating motor 101 is fixedly connected to two fixed gears 102; each rotating ring 7 is fixedly connected to a gear ring 103, and the gear ring 103 is meshed with the fixed gear 102.

[0034] The working steps of the above embodiment are as follows: during the specific operation, the ore to be crushed is poured into the feed hopper 6, the ore falls into the crushing bin 3 through the feed hopper 6, and then the driving motor 4 is controlled to drive the crushing roller 5 to rotate, so as to crush the ore falling into the crushing bin 3, and the crushed ore falls downward through the crushing bin 3; however, in the ore crushing process, incomplete crushing may occur, and some ore materials are discharged outward before being effectively crushed, which may easily cause insufficient ore crushing degree, thereby resulting in poor crushing effect. The prior art uses a filter to screen it out, and then manually pours the screened ore back into the crushing mechanism for crushing, which is cumbersome and inefficient.

[0035] Therefore, when the ore falls downward after being crushed, the crushed ore falls on the working bin 2, and is screened by the screening net 2a at the bottom of the working bin 2, and the incompletely crushed ore is screened out, while the crushed ore that meets the standards falls downward through the screening net 2a, and finally falls on the conveyor belt 10, and the crushed ore is subsequently transported away by controlling the conveyor belt 10 to rotate; at the same time, during the crushing process, the rotating motor 101 is controlled to drive the fixed gear 102 to rotate, and the fixed gear 102 drives the gear ring 103 and the rotating ring 7, as well as other connected parts to rotate, to carry out The rotating ring 7 and the shovel plate 8 are driven to rotate counterclockwise along the inner wall of the working bin 2 from the front to the back, and the incompletely crushed ore screened by the screening net 2a is shoveled up by the rotation of the shovel plate 8. When the incompletely crushed ore is driven by the shovel plate 8 to rotate to the upper part of the working bin 2, the incompletely crushed ore falls downward along the shovel plate 8, and finally falls back into the crushing bin 3 for crushing. In this way, after the incompletely crushed ore is screened out, it is sent back to the crushing bin 3 for crushing again by the rotation of the shovel plate 8, so that when the ore is crushed, the ore can be fully crushed, and the overall operation is convenient and efficient.

[0036] At the same time, when the shovel plate 8 rotates to the lower part of the working bin 2 and scoops up the incompletely crushed ore screened by the screening net 2a, the newly crushed ore continues to fall downward from the upper crushing bin 3. When the shovel plate 8 scoops up the incompletely crushed ore, the newly crushed ore will be scooped up at the same time. Among the newly crushed ores, there are completely crushed ores and incompletely crushed ores. When they are directly sent back to the crushing bin 3 for crushing through the shovel plate 8, the completely crushed ore will be crushed again, causing it to be over-crushed, which not only increases the load and power consumption of the equipment, but also makes it easier for the ore to form dust when it is crushed too finely, and is discharged outward, increasing the loss of the ore. Therefore, when the shovel plate 8 scoops up the ore falling on the screening net 2a, the scooped ore is screened by the screen 9 on the shovel plate 8, and the completely crushed ore is screened out, so that the completely crushed ore The ore can fall downward through the screen 9 and fall back on the screening net 2a, and finally fall through the screening net 2a onto the conveyor belt 10 below, thus preventing the shovel board 8 from sending the completely crushed ore back to the crushing bin 3 for crushing, thereby increasing the load and power consumption of the equipment; and, in the process of the shovel board 8 driving the ore to move upward, when the shovel board 8 passes through the curved plate 117, the shovel board 8 is in close contact with the curved plate 117, so that the shovel board 8, the curved plate 117 and the side wall of the working bin 2 form a groove together, and when the shovel board 8 continues to rotate upward and passes over the curved plate 117, the ore on the shovel board 8 falls downward again, and falls accurately into the crushing bin 3, thus preventing the ore from falling prematurely under the action of its own gravity during the process of the shovel board 8 driving the ore to move upward, and it is impossible to ensure that the shoveled ore can accurately fall into the crushing bin 3;

[0037] Furthermore, when the shovel plate 8 passes through the screening net 2a and scoops up the incompletely crushed ore screened on the screening net 2a, part of the incompletely crushed ore will be embedded in the screening net 2a. Directly shoveling on the shovel plate 8 will not only fail to scoop up the embedded ore, but will further squeeze the ore and make it further embedded in the screening net 2a, causing the screening net 2a to be blocked and damaged; therefore, when the rotating ring 7 drives the shovel plate 8 to rotate counterclockwise from the front to the back, the shovel plate 8 drives the rotating rod 111 and other connected parts to rotate together, and the rotating rod 11 1 is fixedly connected with a linkage gear 113, and the linkage gear 113 is meshed with the gear ring 112. When the shovel plate 8 drives the rotating rod 111 to rotate, under the action of the linkage gear 113, the rotating rod 111 simultaneously rotates clockwise from the front to the back, so that before the shovel plate 8 scoops up the incompletely crushed ore on the screening net 2a, the rotating rod 111 rotates to drive the lever 114 and the scraper 115 to rotate, and the incompletely crushed ore on the screening net 2a is picked up, and then scooped up by the shovel plate 8, so as to prevent the incompletely crushed ore from being embedded in the screening net 2a. Direct shoveling will cause clogging and damage to the screening mesh 2a; at the same time, when the shovel plate 8 drives the completely crushed ore and the incompletely crushed ore to move upward together, the screen 9 is easily blocked by the incompletely crushed ore, making it difficult for the completely crushed ore to fall downward through the screen 9, and eventually it is sent back to the crushing bin 3 for crushing, increasing the load of the equipment. In this regard, the lever 111 is driven to rotate the lever 114 and the scraper 115, and the ore on the shovel plate 8 can be moved and turned, so that the completely crushed ore can fully pass through the screen. 9 falls downward to prevent incompletely crushed ore from clogging the screen 9, making it difficult for completely crushed ore to fall downward through the screen 9; it should be noted that when the rotating rod 111 drives the lever 114 and the scraper 115 to rotate and the ore on the shovel plate 8 is moved and turned, the groove formed by the shovel plate 8, the arc plate 117 and the side wall of the working bin 2 can prevent the ore from being pushed down during the process of moving and turning the ore on the shovel plate 8, thereby ensuring that the incompletely crushed ore can be sent back to the crushing bin 3 for further crushing. Example 2

[0038] On the basis of Example 1, Figure 5-8 As shown, the dust removal component includes a filter 201, an exhaust pipe 202, a drive box 203 and an adsorption sponge 204; the working chamber 2 is connected to two exhaust pipes 202, and the exhaust pipe 202 is connected to the external fan; the working chamber 2 is fixed with a plurality of filters 201, and the filters 201 correspond to the exhaust pipes 202; each exhaust pipe 202 is rotatably connected to an adsorption sponge 204; each exhaust pipe 202 is fixedly connected to a drive box 203, and the drive box 203 is connected to the adsorption sponge 204.

[0039] The scraper 115 is provided with a plurality of bristles 115a, and the screening net 2a can be brushed and cleaned by the bristles 115a to prevent excessive gravel and dust from being attached to the screening net 2a and affecting its normal screening effect.

[0040] It also includes scraping bristles 116 ; each lever 114 is fixedly connected with a plurality of scraping bristles 116 .

[0041] It also includes a water tank 205 and an extrusion plate 207; each exhaust pipe 202 is bolted to a water tank 205, and the water tank 205 is located below the adsorption sponge 204, and the water tank 205 is connected to the exhaust pipe 202; each exhaust pipe 202 is fixed to an extrusion plate 207, and the extrusion plate 207 is in contact with the adsorption sponge 204.

[0042] It also includes an electromagnetic rod 206; each water tank 205 is plugged with an electromagnetic rod 206.

[0043] It also includes paddles 211 and convex balls 212 ; six paddles 211 are fixedly connected to the surface of each adsorption sponge 204 ; and each paddle 211 is fixedly connected to a plurality of convex balls 212 .

[0044] On the basis of the above-mentioned embodiment, a large amount of dust will be generated in the process of crushing the ore. The generated dust is directly discharged to the outside, causing pollution to the surrounding environment. It is easy for the surrounding workers to inhale too much dust and affect their health. Therefore, in the process of crushing, the external fan is controlled to work at the same time, and a water tank 205 filled with water is fixed to the exhaust pipe 202. The dust in the working bin 2 is sucked through the exhaust pipe 202 to extract the dust generated by the crushing. In the process of suction, the ore is isolated by the filter net 201 to avoid extracting the ore together, and the dust sucked into the exhaust pipe 202 is absorbed by the adsorption sponge 204 when passing through the adsorption sponge 204. The dust is filtered out, and at the same time, the driving box 203 is controlled to drive the adsorption sponge 204 to rotate counterclockwise from the front to the back. As the adsorption sponge 204 rotates, the filtered dust is driven to immerse in the water of the water tank 205, and the dust sucked in is treated by the water in the water tank 205. In addition, a squeezing plate 207 is provided. During the rotation of the adsorption sponge 204, the adsorption sponge 204 is squeezed and scraped to squeeze and scrape off the water adsorbed by the adsorption sponge 204, and the dust on the surface of the adsorption sponge 204 is scraped off and cleaned, so as to ensure the adsorption effect of the adsorption sponge 204 on the dust. The staff can replace the water tank 205 later to ensure that the dust can be continuously treated.

[0045] However, during the crushing process, some dust will adhere to the surface of the crushed ore, making it impossible for it to be extracted by the exhaust pipe 202. When the dust attached to the surface of the crushed ore is transported outward together with the ore, it is easy to be blown up again by the outside wind and spread to the outside world, affecting the surrounding environment. Therefore, during the process of the exhaust pipe 202 sucking the dust in the working chamber 2, when the rotating rod 111 drives the lever 114 and the scraper 115 to rotate, the scraper 116 on the lever 114 , brush the surface of the crushed ore to scrape off the dust attached to the surface of the ore so that it can be extracted by the exhaust pipe 202, so as to prevent some dust from being transported to the outside together with the crushed ore and re-spreading to the outside to affect the surrounding environment, and the bristles 115a on the scraper 115 are used to brush and clean the screen 9, the screening net 2a and the filter net 201 when rotating, so as to brush off the dust on their surfaces, so that the dust generated by the crushing can be fully extracted by the exhaust pipe 202;

[0046] At the same time, when metal ores such as iron ore are crushed, some ores containing metal components will be crushed to form dust. Directly extracting the dust will cause the loss of metal ore. Therefore, when the adsorption sponge 204 drives the dust to rotate downward and brings the dust into the water in the water tank 205, the dust in the water tank 205 is magnetically attracted by the electromagnetic rod 206, and the metal dust in the dust is adsorbed and separated. Subsequently, the electromagnetic rod 206 and the metal dust magnetically attracted on its surface can be manually taken out and collected; and, during the rotation of the adsorption sponge 204, the electromagnetic rod 206 is moved by the paddle 211, and the adsorption sponge 204 can The electromagnetic rod 206 can be driven to rotate together. The rotation of the electromagnetic rod 206 enables each part of the electromagnetic rod 206 to magnetically attract the metal dust in the dust, thereby making full use of the electromagnetic rod 206. At the same time, a convex ball 212 is provided on the paddle 211. When the paddle 211 drives the electromagnetic rod 206 to rotate, the metal dust magnetically attracted on the surface of the electromagnetic rod 206 is rubbed through the convex ball 212, and the non-metallic dust mixed in the metal dust is rubbed out, thereby preventing the metal dust from being mixed with some non-metallic dust and being magnetically attracted to the surface of the electromagnetic rod 206, thereby affecting the magnetic attraction effect of the electromagnetic rod 206 on the metal dust in the dust. Example 3

[0047] On the basis of Example 2, Fig. 9 As shown, it also includes a mounting plate 301, a circular tube 302 and a nozzle 303; the conveyor belt 10 is fixedly connected to the mounting plate 301; the mounting plate 301 is fixedly connected to the circular tube 302, and the circular tube 302 is connected to an external water delivery mechanism; the circular tube 302 is connected to a plurality of nozzles 303.

[0048] On the basis of the above-mentioned embodiment, when the dust attached to the surface of the ore is brushed off by the scraper 116, some dust still located near the screening net 2a will fall onto the conveyor belt 10 below together with the ore, and be transported outward by the conveyor belt 10, making it easy for it to be blown by the external wind and lifted up again, causing an impact on the surrounding environment and staff. Therefore, in the process of conveying ore by the conveyor belt 10, the external water supply mechanism is controlled to input water into the circular pipe 302, and the water is sprayed on the ore surface on the conveyor belt 10 and near the screening net 2a through the nozzle 303, so as to completely reduce the generated dust.
