Description

Technical Field

[0001] The utility model relates to the technical field of mine crushing, in particular to a novel crushing device for mines. Background Art

[0002] After ore is mined, it is mostly large-sized raw ore, which needs to be crushed by a crushing device into appropriate sizes before it can be used. The crushing device is widely used in the crushing of various ores and large pieces of materials in industries such as mine smelting, building materials, highways, railways, water conservancy, and chemical engineering.

[0003] After retrieval, the application number CN202221208286.9 discloses a crushing device for mines, including a bottom plate. A crushing box is fixedly installed on the top of the bottom plate. A water tank is fixedly installed on one side of the crushing box. A water filling port is arranged on one side of the water tank. A water pump is fixedly installed on the top of the water tank. The cross-sectional shape of the connecting pipe is a Y-shaped plastic hose, and the two ends of the connecting pipe far from the water pump are connected with two equalizing pipes, which facilitates the connecting pipe to spray the water inside the water tank pumped by the water pump from both sides of the crushing box onto the crushing rollers, facilitating the dust removal treatment of the crushed stones and simultaneously cooling the crushing rollers. Through the arranged screen, it is used to intercept the crushed stones. The stones fall on the top of the screen. Since the movable column is movably arranged inside the movable cylinder, under the action of the elasticity of the spring itself, the screen shakes back and forth, facilitating the shaking off of the relatively wet dust accumulated on the surface area of the stones and falling to the bottom of the crushing box.

[0004] In the above-mentioned prior art solution, when huge stones are dropped from the feed hopper, the stones directly hit the crushing rollers, which has a certain impact on the crushing rollers, extremely easily causes damage to the crushing rollers, affects the normal use of the crusher, and increases the maintenance risk.

[0005] Therefore, we propose a novel crushing device for mines. Content of the Utility Model

[0006] The utility model mainly solves the technical problems existing in the above-mentioned prior art, and provides a novel crushing device for mines.

[0007] To achieve the above purpose, the utility model adopts the following technical scheme. A novel crushing device for mines includes a crushing box, a feed hopper, and a discharge port. A buffer plate is hinged at the top of the feed hopper. Two fixed seats are fixed on the inner wall surface of the feed hopper. Springs are fixedly installed on the tops of the fixed seats. Connecting rods slide inside the inner cavities of the sleeves. A first driving motor is fixed on the side wall surface of the feed hopper. The output shaft end of the first driving motor is connected with a connecting shaft. Three buffer blades are fixedly connected to the side wall surface of the connecting shaft. Slots are opened on the buffer blades. A second driving motor is fixedly connected to the side wall surface of the crushing box. The output shaft end of the second driving motor is equipped with a crushing roller.

[0008] Preferably, a bearing plate is fixed on the side wall surface of the feed hopper, a dust suction pump is installed on the bearing plate, a connecting pipe is connected to the dust suction pump, a collecting pipe is connected to the connecting pipe, and a plurality of dust suction heads are connected to the opposite side wall surfaces of the feed hopper.

[0009] Preferably, the collecting pipe is fixedly connected in a square structure surrounding the side wall surface of the feed hopper, and the dust suction end of the dust suction head is located in the inner cavity of the feed hopper.

[0010] Preferably, the top of the connecting rod is in contact with the bottom of the buffer plate.

[0011] Preferably, two adjacent buffer blades are fixedly arranged in a V shape on the side wall surface of the connecting shaft.

[0012] Preferably, an inclined plate is fixedly connected to the bottom of the inner cavity of the gravel box, and the feed hopper is of a Y-shaped structure.

[0013] Beneficial effects

[0014] The utility model provides a novel gravel device for mines, which has the following beneficial effects:

[0015] 1. For the novel gravel device for mines, the connecting rod, spring, sleeve and buffer plate cooperate to initially buffer the falling gravel. The gravel falls between adjacent buffer blades, and the first driving motor drives the buffer blades to flip. Small gravel is crushed by the crushing roller through the slotted opening, and large gravel falls on the crushing roller through the flipping of the buffer blades, thus avoiding the gravel directly hitting the crushing roller and reducing the maintenance risk.

[0016] 2. For the novel gravel device for mines, when the second driving motor is started, the dust suction pump is started at the same time. The dust generated during the crushing process is sucked out through the dust suction heads, avoiding the dust from spreading in the air. Description of the drawings

[0025] Embodiment: A new type of gravel device for mines, as Figures 1-3 shown, includes a gravel box 1. The top of the gravel box 1 is connected to a feed hopper 2 with a Y-shaped structure. The bottom of the inner cavity of the gravel box 1 is fixedly connected with an inclined plate 102. A discharge port 101 is opened at a position on one side of the gravel box 1 corresponding to the inclined plate 102. One side of the top of the feed hopper 2 is hinged with a buffer plate 201. Two fixed seats 6 are fixedly connected to the side wall surface of the inner cavity of the feed hopper 2 and below the buffer plate 201. The tops of the two fixed seats 6 are fixedly connected with a sleeve 601. A spring 602 is installed in the inner cavity of the sleeve 601. A connecting rod 603 is slidably arranged in the inner cavity of the sleeve 601 and on top of the spring 602. The tops of the two connecting rods 603 are in contact with the bottom of the buffer plate 201. A first drive motor 3 is fixedly installed on the side wall surface of the discharge end of the feed hopper 2. The output shaft end of the first drive motor 3 is fixedly connected with a connecting shaft 301. Three L-shaped buffer blades 302 are fixedly connected to the side wall surface of the connecting shaft 301. Two adjacent buffer blades 302 are fixedly arranged in a V shape on the side wall surface of the connecting shaft 301. A slotted opening 303 is opened on the buffer blade 302. The center of the side wall surface of the gravel box 1 is fixedly connected with a second drive motor 5. The output shaft end of the second drive motor 5 is installed with a crushing roller 501.

[0026] A bearing plate 401 is fixedly connected to the side wall surface of the feed hopper 2. A dust suction pump 4 is installed on the bearing plate 401. A connecting pipe 402 is connected to the dust suction pump 4. A collecting pipe 403 is connected to the connecting pipe 402. The collecting pipe 403 is fixedly connected to the side wall surface of the feed hopper 2 in a square-shaped structure. A plurality of dust suction heads 404 are connected to the opposite side wall surfaces of the feed hopper 2. The dust suction ends of the dust suction heads 404 are located in the inner cavity of the feed hopper 2.

[0027] The working principle of the present utility model:

[0028] During use, crushed stones are poured into the top of the feed hopper 2. At this time, the crushed stones first fall on the buffer plate 201. Since the top of the connecting rod 603 is in contact with the bottom of the buffer plate 201, the buffer plate 201 is pressed down under the gravity of the crushed stones. At this time, the connecting rod 603 compresses the spring 602, and the spring 602 plays a preliminary buffering role for the crushed stones. Then, the crushed stones fall between adjacent buffer blades 302. The first driving motor 3 is started to drive the buffer blades 302 to flip. Small crushed stones fall on the crushing roller 501 through the slots 303 for crushing, and large crushed stones fall on the crushing roller 501 through the flipping of the buffer blades 302.

[0029] During use, the dust suction pump 4 is started while the second driving motor 5 is started. Dust generated during the crushing process is sucked out through the dust suction heads 404 to prevent dust from spreading in the air.
