[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0025] A dust-proof jaw crusher, such as Figure 1 and Figure 2 As shown, it includes a dustproof box 10, a support seat 14 is welded at the bottom of the dustproof box 10, a conveying assembly for conveying materials is arranged above the support seat 14, and the conveying assembly includes a conveying plate 15, a small eccentric wheel 16, a chain 17, a first gear 18 and a second gear 19, the conveying plate 15 is fixedly connected to the small eccentric wheel 16, the chain 17 is transmission-connected to the first gear 18 and the second gear 19, the first gear 18 and the second gear 19 are rotationally connected to the support seat 14 and are both fixedly connected to the small eccentric wheel 16; as shown Figure 1 and Figure 2As shown, a stabilizing seat 20 is welded above the supporting seat 14, and a bracket is welded above the stabilizing seat 20. Two rotating holes are symmetrically provided in the bracket, and bearings are provided in the two rotating holes, and different shaft columns are rotatably connected through the bearings. The shaft columns include a first shaft column and a second shaft column, and different No. 2 gears 19 are fixedly connected to both ends of the first shaft column, and the second shaft column is longer than the first shaft column. A second rotating hole is provided on one side of the dustproof box 10, and a second bearing is provided in the second rotating hole, and the second shaft column is rotatably connected through the second bearing. The third placement plate is located directly below the second shaft column, wherein the output end of the second motor 12 is connected to one end of the second shaft column, and the other end of the second shaft column and the curved surface are respectively fixedly connected to different No. 1 gears 18; as shown Figure 2 As shown, the first gear 18 and the second gear 19 are located on the same horizontal plane and are both meshed with the chain 17. The first gear 18 is connected to the second gear 19 through the chain 17. A plurality of small eccentric wheels 16 are provided, one of which is fixedly connected to the first gear 18 and is located at a position where the first gear 18 deviates from the center of the circle, and the other small eccentric wheel 16 is fixedly connected to a position where the second gear 19 deviates from the center of the circle. The two small eccentric wheels 16 are symmetrically fixed at both ends of the conveying plate 15; Figure 2 As shown, the conveying plate 15 is wavy in shape, suspended above the supporting seat 14 , and rotatably connected to the stabilizing seat 20 via a first gear 18 and a second gear 19 .

[0026] The working principle is as follows: start the second motor 12, drive the No. 1 gear 18 to rotate, thereby meshing the chain 17, and at the same time make the chain 17 mesh with the No. 2 gear 19, drive the No. 2 gear 19 to rotate. Due to the rotation of the No. 1 gear 18 and the No. 2 gear 19, the small eccentric wheel 16 connected thereto will be driven to rotate around the No. 1 gear 18 and the No. 2 gear 19, and then drive the ups and downs movement of the conveying plate 15.

Since the length of the support seat is less than the length inside the dustproof box 10, it will form a notch for discharging. Since the angle of the conveying plate 15 is large, the slope formed between the conveying plate 15 and the support seat 14 is relatively gentle, which can make the material fall more gently, so as to reduce the dust caused by collision with each other, thereby reducing the pollution to the environment and the damage to the respiratory health of the staff.

[0027] like Figure 1 and Figure 4As shown, a through hole is opened on one side of the dustproof box 10, a rubber sleeve for blocking the gap is arranged in the through hole, and a water pipe 11 is clamped by the rubber sleeve, and three adjacent sides where the dustproof box 10 is connected to the water pipe 11 are welded with different placement plates, and the placement plates include a first placement plate, a second placement plate and a third placement plate, the first placement plate is located on the opposite side of the water pipe 11, and a dust storage box 25 is placed on the top, the second placement plate and the third placement plate are respectively located on two adjacent sides where the dustproof box 10 is connected to the water pipe 11, and different motors 12 are placed on the top, and three motors 12 are arranged, and the third motor 12 is placed on the top of the dustproof box 10; as shown Figure 1 and Figure 4 As shown, a square hole is provided on the side of the dust box 10 opposite to the dust box 25, and an L-shaped centrifugal fan 26 is clamped in the square hole. A third rotating hole is provided above the dust box 10, which is located directly above the air outlet of the L-shaped centrifugal fan 26. A third bearing is provided in the third rotating hole, wherein the output end of the third motor 12 is connected to a rotating column, which is rotatably connected to the dust box 10 through the third bearing, and one end of the rotating column is fixedly connected to the rotating blades inside the L-shaped centrifugal fan 26. A threaded hole is provided above the dust box 25, and a threaded cover 13 is threadedly connected through the threaded hole; as shown Figure 1 , Figure 3 and Figure 5 As shown, a square plate is welded on the inner wall of the dustproof box 10, a spring 24 is welded on the other side of the square plate, a moving block 23 is welded on the other end of the spring 24, a fourth rotating hole is opened on one side of the dustproof box 10, which is located just above the second placement plate, and a fourth bearing is arranged inside it, wherein the output end of the first motor 12 is connected to a short shaft column, the short shaft column is rotatably connected to the dustproof box 10 through the fourth bearing, and the other end is fixedly connected to a large eccentric wheel 21, and the large eccentric wheel 21 is fixedly connected to the position away from the circle There is a rotating cylinder, on which a swing bracket 22 is fixedly connected, a square block is provided at the middle side end of the swing bracket 22, different movable circular shaft columns are provided on both sides of the square block and both sides of the moving block 23, and a connecting rod 27 is rotatably connected through the circular shaft column, the swing bracket 22 and the moving block 23 are both rotatably connected to the connecting rod 27, an arc groove plate is provided on the inner wall surface of the dustproof box 10 on the side opposite to the swing bracket 22, an arc convex plate is provided on the oblique side surface of the swing bracket 22, and the arc convex plate is slidably connected to the arc groove plate.

[0028] The working principle is as follows. Due to the weight of the stones, the overall crushing requirements for the device are very high. This device uses the principle of the centrifugal wheel. When the motor 12 is started, the large eccentric wheel will drive the swing bracket 22 to rotate eccentrically. At the same time, the moving block 23 connected by the connecting rod 27 will be driven up and down. At the same time, because the spring 23 is connected to the square plate, it is pulled and limited by the elastic force therein. At this time, the arc convex plate on the side of the swing bracket 22 and the arc groove plate on the inner wall of the dustproof box 10 rub against each other. Dust will appear while crushing the material. At this time, the water source can be connected through the external water pipe 11, and the principle of water mixing with dust can be used to settle the dust. However, this method is only suitable for situations where it will not be affected or reacted with water. Another way is to open the third 12 and use the L-shaped centrifugal fan The machine 26 absorbs the dust, and then transports it into the dust box 25 through the internal channel. Here, the interior of the dust box 25 can be protected from a dust bag, which can effectively prevent the dust from being contaminated with the interior of the dust box 25, and can also facilitate the cleaning of the staff. A threaded cover 13 is used on the top of the dust box 25. When it is disassembled, a rubber ring is placed on the top of the thread to ensure that the dust does not leak out. In summary, the crushing form driven by the centrifugal wheel principle can resolve the impact force of the stone through the tension of the spring 23. The connecting rod 27 is used to stabilize the device and further buffer it, avoiding the resistance caused by the weight of the stone, ensuring the stability of the device operation while reducing the number of maintenance times by the staff, thereby ensuring work efficiency.
