[0002] The high-efficiency ore crushing and grinding device is used for ore crushing and fine grinding, and is suitable for mining, building materials production, metallurgy and chemical industries. It can process a variety of ores such as talc, calcite, dolomite, fluorite, magnesite, and alum. It features a large crushing ratio and high grinding precision, and can quickly convert blocky ores into qualified particle size powder, reduce energy consumption, improve production efficiency, meet the fine processing needs of ore raw materials in industrial production, and provide high-quality raw materials for subsequent smelting, building materials preparation and other processes.

[0003] In ore crushing and processing, traditional crushing equipment often adopts a single-stage crushing method, which is prone to uneven crushing and results in the grinding precision not meeting product requirements. Furthermore, large pieces of material that fail to meet the standards are prone to remain on the screen plate. If not handled in time, they can easily cause the screen plate to become clogged, thus restricting the efficiency of continuous production. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an efficient crushing and grinding device for ore, which can drive the crushing roller to rotate in contact with the semi-circular screen plate through the grinding component, and ensure that the crushing roller is always in close contact with the material, thereby improving the thoroughness of crushing, reducing the residue of large pieces of material, and ensuring uniform particle size of the output.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0006] A high-efficiency ore crushing and grinding device includes: a crushing box, a feeding frame connected to the top of the crushing box and communicating with the interior of the crushing box, baffles rotatably connected to both sides of the inner wall of the feeding frame via hinges, a discharge frame connected to the bottom of the crushing box, a semi-circular screen plate installed inside the crushing box, multiple arc-shaped industrial springs connected to the bottom of the baffles, and a grinding assembly disposed at the top of the crushing box for grinding materials that are not completely crushed and cannot pass through the semi-circular screen plate. The grinding assembly includes: crushing rollers, half gears, and large gears. Two meshing large gears are disposed on one side of the crushing box, and two crushing rollers are disposed inside the crushing box. One end of each of the two crushing rollers is connected to one side of the corresponding large gear, and the other end of each of the two crushing rollers penetrates the crushing box and is connected to a half gear.

[0007] Preferably, a pinion is rotatably connected to one side of the crushing box. The pinion is located between the two half-gears. The pinion is the same size as the two half-gears and meshes with them. A transmission wheel a is connected to one side of the pinion. A transmission wheel b is provided at the bottom of the transmission wheel a. A transmission belt is provided between the transmission wheel b and the transmission wheel a. A rotating rod is connected to one side of the transmission wheel b. One end of the rotating rod extends into the interior of the crushing box and is rotatably connected to the inner wall of the crushing box.

[0008] Preferably, the bottom of the rotating rod is connected to two driving rods, each driving rod has a storage groove inside, and each storage groove is equipped with an industrial spring. The bottom of each industrial spring is provided with an extension rod, and the bottom of each extension rod is connected to a fixed rod. A crushing roller is rotatably connected between the two fixed rods. The bottom of the crushing roller is in contact with the top of the semi-circular screen plate. A support base is connected to one side of the crushing box, and a motor is installed on the top of the support base.

[0018] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0019] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1-6 As shown, a high-efficiency ore crushing and grinding device includes: a crushing box 1, a feed frame 101 connected to the top of the crushing box 1, the feed frame 101 communicating with the interior of the crushing box 1, baffles 102 rotatably connected to both sides of the inner wall of the feed frame 101 via hinges, a discharge frame 103 connected to the bottom of the crushing box 1, a semi-circular screen plate 104 installed inside the crushing box 1, multiple arc-shaped industrial springs connected to the bottom of the baffles 102, and a grinding assembly set at the top of the crushing box 1 for grinding materials that are not completely crushed and cannot pass through the semi-circular screen plate 104. The grinding assembly includes: crushing rollers 2, half gears 201 and large gears 202, two meshing large gears 202 set on one side of the crushing box 1, two crushing rollers 2 set inside the crushing box 1, one end of each crushing roller 2 connected to one side of the corresponding large gear 202, and the other end of each crushing roller 2 penetrating the crushing box 1 and connected to a half gear 201.

[0021] In this grinding assembly, the crushing roller 2, half gear 201, and large gear 202 are configured to drive the rotating rod 402 through the transmission wheel a301, transmission belt 401, and transmission wheel b4 via the transmission wheel 201 and small gear 3. This drives the crushing roller 701 to rotate in contact with the semi-circular screen plate 104, thus performing secondary grinding on large pieces of material that have not passed through the semi-circular screen plate 104. The industrial spring 6 applies elastic pressure through the extension rod 601 to ensure that the crushing roller 701 is always in close contact with the material, thereby improving the thoroughness of crushing, reducing the residue of large pieces of material, and ensuring uniform particle size of the output.

[0022] Among them, a small gear 3 is rotatably connected to one side of the crushing box 1. The small gear 3 is located between two half gears 201. The small gear 3 is the same size as the two half gears 201 and meshes with each other. A transmission wheel a301 is connected to one side of the small gear 3. A transmission wheel b4 is provided at the bottom of the transmission wheel a301. A transmission belt 401 is provided between the transmission wheel b4 and the transmission wheel a301. A rotating rod 402 is connected to one side of the transmission wheel b4. One end of the rotating rod 402 extends into the interior of the crushing box 1 and is rotatably connected to the inner wall of the crushing box 1.

[0023] First, the ore material is fed into the feed frame 101 and falls between two opposing rotating crushing rollers 2 for primary crushing. The primary crushing is driven by the motor 302, which drives a large gear 202 to rotate through the drive shaft. This large gear 202 meshes with another large gear 202, thereby driving the two crushing rollers 2 to rotate synchronously in opposite directions, extruding and shearing the material.

[0024] Furthermore, the material that has undergone primary crushing falls onto the semi-circular screen plate 104. Fine particles of the correct size pass directly through the screen holes and are discharged from the discharge frame 103 below, while large pieces of material that fail to pass through the screen holes remain on the top of the semi-circular screen plate 104 and enter the secondary grinding process.

[0025] Among them, the bottom of the rotating rod 402 is connected to two driving rods 5, and the two driving rods 5 have a storage groove 501 inside. Each of the two storage grooves 501 is equipped with an industrial spring 6. The bottom of the industrial spring 6 is equipped with an extension rod 601. The bottom of each of the two extension rods 601 is connected to a fixing rod 7. A crushing roller 701 is rotatably connected between the two fixing rods 7. The bottom of the crushing roller 701 is in contact with the top of the semi-circular screen plate 104. A support base 303 is connected to one side of the crushing box 1. A motor 302 is installed on the top of the support base 303. One side of the motor 302 is driven by a drive shaft connected to the corresponding large gear 202.

[0026] Furthermore, the half gears 201 at the ends of the two crushing rollers 2 alternately mesh with the pinion 3. When the crushing rollers 2 rotate, the two half gears 201 rotate accordingly and periodically drive the pinion 3 to rotate intermittently in both directions. The shaft of the pinion 3 drives the transmission wheel a301 to rotate, and transmits power to the transmission wheel b4 through the transmission belt 401, thereby driving the rotating rod 402 to rotate.

[0027] Finally, the rotation of the rotating rod 402 drives the two driving rods 5 at its bottom to move. The driving rod 5 has a receiving groove 501 inside, and an industrial spring 6 is installed in the receiving groove 501. This allows the crushing roller 701 to always be tightly attached to the arc-shaped surface of the semi-circular screen plate 104 under the elastic force of the industrial spring 6 when it moves with the driving rod 5. The roller continuously pushes, rolls and grinds the large pieces of material stuck on it. Due to the special shape of the semi-circular screen plate 104, as the crushed material in the middle of the semi-circular screen plate 104 is ground and passes through the plug hole, the crushed material on both sides will flow to the middle position of the semi-circular screen plate 104 until it is crushed by the crushing roller 701 to a particle size that can pass through the screen hole. Finally, it is discharged from the discharge frame 103, ensuring the uniformity of the output particle size.

[0028] Working principle:

[0029] First, the ore material is fed into the feed frame 101 and falls between two opposing rotating crushing rollers 2 for primary crushing. The primary crushing is driven by the motor 302, which drives a large gear 202 to rotate through the drive shaft. This large gear 202 meshes with another large gear 202, thereby driving the two crushing rollers 2 to rotate synchronously in opposite directions, extruding and shearing the material.

[0030] Furthermore, the material that has undergone primary crushing falls onto the semi-circular screen plate 104. Fine particles of the correct size pass directly through the screen holes and are discharged from the discharge frame 103 below, while large pieces of material that fail to pass through the screen holes remain on the top of the semi-circular screen plate 104 and enter the secondary grinding process.

[0031] Furthermore, the half gears 201 at the ends of the two crushing rollers 2 alternately mesh with the pinion 3. When the crushing rollers 2 rotate, the two half gears 201 rotate accordingly and periodically drive the pinion 3 to rotate intermittently in both directions. The shaft of the pinion 3 drives the transmission wheel a301 to rotate, and transmits power to the transmission wheel b4 through the transmission belt 401, thereby driving the rotating rod 402 to rotate.

[0032] Finally, the rotation of the rotating rod 402 drives the two driving rods 5 at its bottom to move. The driving rod 5 has a receiving groove 501 inside, and an industrial spring 6 is installed in the receiving groove 501. This allows the crushing roller 701 to always be tightly attached to the arc-shaped surface of the semi-circular screen plate 104 under the elastic force of the industrial spring 6 when it moves with the driving rod 5. The roller continuously pushes, rolls and grinds the large pieces of material stuck on it. Due to the special shape of the semi-circular screen plate 104, as the crushed material in the middle of the semi-circular screen plate 104 is ground and passes through the plug hole, the crushed material on both sides will flow to the middle position of the semi-circular screen plate 104 until it is crushed by the crushing roller 701 to a particle size that can pass through the screen hole. Finally, it is discharged from the discharge frame 103, ensuring the uniformity of the output particle size.

[0033] Furthermore, the reference model of the industrial spring 6 is XY-1239124141. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Therefore, this utility model will not explain the control method and circuit connection in detail.
