Description

Technical Field

[0001] This utility model relates to the field of mining machinery technology, specifically to a splash-proof mining crushing device. Background Technology

[0002] In the mining industry, crushing equipment is a key piece of equipment used to break raw ore from larger lumps into smaller particles for subsequent extraction, processing, or transportation. Mining crushing equipment plays a vital role in mining and mineral processing. Ore usually exists in its original form, and its particle size and hardness vary depending on the type of ore. Jaw crushers are a common type of crushing machinery.

[0003] The current crusher has an open top. When stones are put into it, the crushed stones are prone to being ejected and splashed under the pressure, which poses a certain safety hazard. Moreover, the process of adjusting the size of the discharge port at the bottom of the current crusher is relatively cumbersome. By adding or removing shims between the rear thrust plate support and the rear wall of the frame, the position of the toggle plate is changed, which is not very practical. Utility Model Content

[0004] The purpose of this invention is to provide a splash-proof mining crushing device to solve the above-mentioned problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This utility model provides a splash-proof mining crushing device, including a feeding hopper. A stone inlet is provided on one side of the upper surface of the feeding hopper. An elastic baffle structure for preventing stone fragments from splashing is provided in the stone inlet. A stationary jaw plate is fixedly connected to one side of the inner wall of the feeding hopper, and a movable jaw plate adapted to the stationary jaw plate is provided in the feeding hopper. A drive component for driving the upper part of the movable jaw plate to make a circular motion is provided in the feeding hopper. A support plate is provided on the lower side of the feeding hopper. The end of the support plate abuts against the lower side wall of the movable jaw plate, and an adjustment component for adjusting the position of the support plate is provided on the side wall of the feeding hopper.

[0007] Preferably, the elastic baffle structure includes several connecting plates, which are evenly fixedly connected to both sides of the stone-throwing opening. Each connecting plate has a splash guard rotatably connected to its end. The splash guards on both sides cooperate to completely block the stone-throwing opening. A torsion spring is provided below the connecting plate, and the two ends of the torsion spring are respectively connected to the connecting plate and the splash guard.

[0008] Preferably, slope protection plates are fixedly connected to both sides of the stone-throwing opening, and the two slope protection plates are respectively located above several connecting plates on both sides.

[0009] Preferably, several biting teeth are fixedly connected to the opposite surfaces of the stationary jaw plate and the movable jaw plate, and the teeth of several biting teeth on both sides are designed to be opposite.

[0010] Preferably, the drive assembly includes circular plates rotatably connected to the inner walls of both sides of the hopper, the two circular plates are located on the same axis, and a connecting shaft is fixedly connected at an eccentric position between the two circular plates. The upper end of the moving jaw plate is rotatably connected to the connecting shaft, and a transmission structure is provided on the side wall of the hopper for simultaneously driving the two circular plates to rotate.

[0011] Preferably, the transmission structure includes two large flywheels for driving the two circular plates to rotate, and the two large flywheels are located on the outer walls of the two sides of the hopper. A rotating shaft is rotatably connected inside the hopper, and small flywheels are fixedly connected to both ends of the rotating shaft through the side walls of the hopper. The large flywheels and small flywheels are connected by a transmission belt. A motor for driving the rotating shaft to rotate is fixedly installed on one side wall of the hopper.

[0012] Preferably, the large flywheel is equipped with a counterweight, and the transmission belt has several components.

[0013] Preferably, both ends of the top support plate are fixedly connected with sliding strips, and the inner walls on both sides of the hopper are provided with sliding grooves that are slidably connected to the sliding strips. Several rollers are rotatably connected to the end of the top support plate, and the rollers abut against the side wall of the moving jaw plate.

[0014] Preferably, the adjusting assembly includes a threaded rod rotatably connected to the middle of the support plate, and a threaded sleeve that is threadedly connected to the threaded rod is fixedly connected to the side wall of the hopper, and the threaded sleeve is provided with an insertion structure for fixing the threaded rod.

[0015] Preferably, the insertion structure includes a pin hole that passes through the threaded sleeve, into which a pin is inserted, and a plurality of fixing holes that are inserted through the threaded rod to engage with the pin.

[0016] The beneficial effects are:

[0017] When the moving jaw plate moves away from the stationary jaw plate, the distance between them increases, and the stones fall a certain distance under gravity. This process repeats to crush the stones. When the stones fall completely into the crushing area between the stationary and moving jaw plates, the splash guard rotates and resets under elastic action. When the stones are ejected, they can be effectively blocked by the splash guard. By rotating the threaded rod, it moves horizontally in the threaded sleeve. At this time, the end of the support plate moves the lower end of the moving jaw plate closer to the stationary jaw plate, thereby adjusting the distance between the lower ends of the two plates. This effectively prevents the ejection and splashing of crushed stones. At the same time, the adjustment process of the discharge port at the lower end of the moving jaw plate is quick and convenient, improving its practicality. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] See Figures 1-5As shown, this utility model provides a splash-proof mining crushing device, including a hopper 1, a stone inlet 2 on one side of the upper surface of the hopper 1, an elastic baffle structure 3 for preventing stone fragments from splashing in the stone inlet 2, a stationary jaw plate 7 fixedly connected to one side of the inner wall of the hopper 1, and a movable jaw plate 8 adapted to the stationary jaw plate 7 in the hopper 1, a drive assembly 4 for driving the upper end of the movable jaw plate 8 to make circular motion in the hopper 1, a support plate 10 on the lower side of the hopper 1, the end of the support plate 10 abutting against the lower side of the side wall of the movable jaw plate 8, and an adjustment assembly 6 for adjusting the position of the support plate 10 on the side wall of the hopper 1.

[0028] Reference Figure 2 As shown, the elastic baffle structure 3 includes several connecting plates 301, which are uniformly fixedly connected to both sides of the stone-feeding opening 2. Each connecting plate 301 has a splash guard 302 rotatably connected to its end. The splash guards 302 on both sides cooperate to completely block the stone-feeding opening 2. A torsion spring 303 is provided below the connecting plate 301, and both ends of the torsion spring 303 are connected to the connecting plate 301 and the splash guard 302 respectively. Slope protection plates 304 are fixedly connected to both sides of the stone-feeding opening 2, and the two slope protection plates 304 are respectively located above the connecting plates 301 on both sides. After a stone is placed into the stone inlet 2, the stone presses down on the splash guard 302, which overcomes the elastic force of the torsion spring 303 and rotates downward until the stone contacts the stationary jaw plate 7 and the movable jaw plate 8. As the movable jaw plate 8 reciprocates and squeezes, the stone falls a certain distance under gravity. This reciprocating motion can crush the stone. When the stone falls completely into the squeezing area between the stationary jaw plate 7 and the movable jaw plate 8, the splash guard 302 rotates back to its original position under elastic action. When the stone is ejected, it can be effectively blocked by the splash guard 302. The slope protection plate 304 can protect the connecting plate 301 and prevent the stone from deforming the connecting plate 301.

[0029] Specifically, several biting teeth 9 are fixedly connected to the opposite surfaces of the stationary jaw plate 7 and the movable jaw plate 8. The teeth of the several biting teeth 9 on both sides are designed to be opposite, so that when the movable jaw plate 8 moves back and forth toward the stationary jaw plate 7, the tip of the biting teeth 9 can effectively act on the surface of the stone, thereby improving the stone crushing effect.

[0030] Reference Figure 4As shown, the drive assembly 4 includes two circular plates 401 rotatably connected to the inner walls of both sides of the hopper 1. The two circular plates 401 are located on the same axis, and a connecting shaft 402 is fixedly connected to the eccentric position between the two circular plates 401. The upper end of the moving jaw plate 8 is rotatably connected to the connecting shaft 402. The side wall of the hopper 1 is provided with a transmission structure 5 for simultaneously driving the two circular plates 401 to rotate. The large flywheel 501 then drives the circular plates 401 to rotate. At this time, since the connecting shaft 402 between the two circular plates 401 is eccentrically designed, it can drive the upper end of the moving jaw plate 8 to rotate in a circle, thereby causing the moving jaw plate 8 to move back and forth towards or away from the stationary jaw plate 7 to achieve the extrusion effect.

[0031] Reference Figure 3 As shown, the transmission structure 5 includes two large flywheels 501 for driving the rotation of two circular plates 401 respectively. The two large flywheels 501 are located on the outer walls of the two sides of the feeding hopper 1. A rotating shaft 502 is rotatably connected inside the feeding hopper 1. Both ends of the rotating shaft 502 pass through the side wall of the feeding hopper 1 and are fixedly connected to small flywheels 503. The large flywheels 501 and small flywheels 503 are connected by a transmission belt 504. A motor 505 for driving the rotating shaft 502 is fixedly installed on one side wall of the feeding hopper 1. The motor 505 drives the rotating shaft 502 to rotate. 2. When rotating, the small flywheels 503 at both ends rotate together. Driven by several transmission belts 504, they drive the large flywheel 501 to rotate. The large flywheel 501 then drives the circular plate 401 to rotate. Since the connecting shaft 402 between the two circular plates 401 is eccentrically designed, it can drive the upper end of the moving jaw plate 8 to rotate in a circle, thereby causing the moving jaw plate 8 to move closer to or further away from the stationary jaw plate 7 to achieve a squeezing effect. The flywheel and belt body here can be configured according to the actual situation, such as sprockets and chains, or synchronous pulleys and synchronous belts, in order to achieve an anti-slip effect.

[0032] Specifically, the large flywheel 501 is equipped with a counterweight, and there are several transmission belts 504. By setting a counterweight in the large flywheel 501, the large flywheel 501 can have a large inertia after rotation, which effectively reduces the workload of the motor 505. Several transmission belts 504 can effectively drive the large flywheel 501 to rotate and prevent slippage.

[0033] Reference Figure 5 As shown, both ends of the top support plate 10 are fixedly connected with slide bars 11. The inner walls of both sides of the hopper 1 are provided with slide grooves 12 that are slidably connected to the slide bars 11. Several rollers 13 are rotatably connected to the end of the top support plate 10, and the rollers 13 abut against the side wall of the moving jaw plate 8. The top support plate 10 can be moved laterally by rotating the threaded rod 601, so that the slide bars 11 can slide stably in the slide grooves 12. By abutting against the moving jaw plate 8 through the rollers 13, the contact process between the moving jaw plate 8 and the top support plate 10 during the reciprocating rotation and extrusion process can be smoother.

[0034] As an optional implementation, the adjusting assembly 6 includes a threaded rod 601 rotatably connected to the middle of the support plate 10. A threaded sleeve 602, which is threadedly connected to the threaded rod 601, is fixedly connected to the side wall of the hopper 1. The threaded sleeve 602 is provided with an insertion structure for fixing the threaded rod 601. The insertion structure includes a pin hole 603 that passes through the threaded sleeve 602. A pin 604 is inserted into the pin hole 603. A plurality of pins 604 are passed through the threaded rod 601 and inserted into the pins 604. The threaded rod 601 is rotated through the fixed hole 605, causing it to move horizontally within the threaded sleeve 602. At this time, the end of the support plate 10 drives the lower end of the moving jaw plate 8 to approach the stationary jaw plate 7, thereby adjusting the distance between the lower ends of the two. After rotating to the appropriate position, the fixed hole 605 is aligned with the pin hole 603. The pin 604 is then inserted into both the pin hole 603 and the fixed hole 605 simultaneously, thus fixing the position of the threaded rod 601 and preventing it from loosening during prolonged equipment vibration.

[0035] The working principle of this utility model:

[0036] In use, stones are placed into the hopper 1 through the stone inlet 2. At this time, the stones press down on the splash guard 302, overcoming the elastic force of the torsion spring 303, and rotate downwards until the stones contact the stationary jaw plate 7 and the moving jaw plate 8. The motor 505 drives the two small flywheels 503 to rotate, and the transmission belt 504 drives the large flywheel 501 and the circular plate 401 to rotate together. At this time, the upper end of the moving jaw plate 8 reciprocates in a small range of circular motion with the connecting shaft 402 located in an eccentric position on the circular plate 401. When the moving jaw plate 8 moves closer to the stationary jaw plate 7, it squeezes the stones and drives them to move. When the moving jaw plate 8 moves away from the stationary jaw plate 7, the distance between them increases, and the stone falls a certain distance under gravity. This process is repeated to crush the stone. When the stone falls completely into the crushing area between the stationary jaw plate 7 and the moving jaw plate 8, the splash guard 302 rotates and resets under elastic action. When the stone is ejected, it can be effectively blocked by the splash guard 302. By rotating the threaded rod 601, it moves horizontally in the threaded sleeve 602. At this time, the end of the support plate 10 drives the lower end of the moving jaw plate 8 to approach the stationary jaw plate 7, thereby adjusting the distance between the lower ends of the two.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
