Abstract
Description
Technical Field
[0001] This utility model relates to the field of ore processing technology, specifically to an ore mining and crushing device. Background Technology
[0002] After being crushed and ground, the ore mined from mines can be used in engineering fields such as the cement industry and the sand and gravel industry. Crushing the ore is to increase the contact area and improve the utilization rate of raw materials.
[0003] Existing crushers typically crush ore by rotating two crushing rollers toward the center. However, during the crushing process, due to the large quantity and varied shapes of the ore, it is easy for the ore to become clogged at the feed hopper, requiring a manual unblocking device, resulting in low crushing efficiency. Therefore, in order to solve the above-mentioned technical problems, this utility model provides an ore mining and crushing device. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an ore mining and crushing device.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an ore mining crushing device, comprising a crushing shell and a pair of crushing rollers rotatably installed inside the crushing shell. A pair of motors are fixedly installed on the outer surface of the crushing shell, and the output ends of the two motors are respectively fixedly connected to one end of the two crushing rollers. A feed hopper is fixedly installed at the top of the crushing shell. A movable pressure rod is slidably installed on the crushing shell below the discharge port of the feed hopper. Multiple unblocking rods are fixedly installed on the movable pressure rod. L-shaped blocks are fixedly installed at both ends of the movable pressure rod along its length. An eccentric disc is rotatably installed on the crushing shell, and the edge of the eccentric disc is tightly fitted with the L-shaped blocks. A transmission component is provided between the eccentric disc and the crushing rollers, and an elastic component is provided between the L-shaped blocks and the feed hopper.
[0006] Preferably, the transmission component is a transmission belt, one end of which is sleeved on one end of the crushing roller, and the other end is sleeved on the eccentric disc.
[0007] Preferably, the elastic element is a spring, with its top end fixedly connected to the feed hopper and its bottom end fixedly connected to the L-shaped block.
[0008] Preferably, a slide bar is fixedly installed between the feed hopper and the crushing shell, and one end of the slide bar passes through the interior of the L-shaped block and is slidably connected to the L-shaped block.
[0009] Preferably, a fixing plate is fixedly installed on the feed hopper, and the fixing plate is fixedly connected to the crushing shell by multiple support rods. Beneficial effects
[0010] Compared with the prior art, the present invention provides an ore mining and crushing device, which has the following beneficial effects:
[0011] A movable pressure rod is installed below the discharge port of the feed hopper. Multiple unblocking rods are fixedly installed on the movable pressure rod. L-shaped blocks are fixedly installed at both ends of the movable pressure rod along its length. The L-shaped blocks are slidably installed on the crushing shell. An eccentric disc is rotatably installed on the crushing shell. The edge of the eccentric disc is in close contact with the L-shaped blocks. A transmission component is installed between the eccentric disc and the crushing roller. An elastic component is installed between the L-shaped blocks and the feed hopper. This not only prevents the discharge port of the feed hopper from getting blocked, but also allows the ore to enter the space between the two crushing rollers for crushing more quickly.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0021] Please combine Figures 1 to 3 As shown, this utility model provides an ore mining and crushing device. The crushing device includes a crushing shell 1 and a pair of crushing rollers 2 rotatably installed inside the crushing shell 1. A pair of motors 3 are fixedly installed on the outer surface of the crushing shell 1. The output ends of the two motors 3 are respectively fixedly connected to one end of the two crushing rollers 2. The two motors 3 respectively cause the two crushing rollers 2 to rotate relative to each other. When the ore enters between the two crushing rollers 2, the ore can be crushed. A feed hopper 4 is provided on the top of the crushing shell 1. A fixing plate 5 is fixedly installed on the feed hopper 4. The fixing plate 5 is fixedly connected to the crushing shell 1 through multiple support rods 6.
[0022] A movable pressure rod 7 is installed on the crushing shell 1 and below the discharge port of the feed hopper 4. L-shaped blocks 11 are fixedly installed at both ends of the movable pressure rod 7 along its length. A sliding rod 12 is fixedly installed between the feed hopper 4 and the crushing shell 1. One end of the sliding rod 12 passes through the interior of the L-shaped block 11 and is slidably connected to the L-shaped block 11. Multiple unblocking rods 8 are fixedly installed on the movable pressure rod 7. An eccentric disc 10 is rotatably installed on the crushing shell 1. The edge of the eccentric disc 10 is tightly fitted with the L-shaped block 11. A transmission belt 9 is provided between the eccentric disc 10 and the crushing roller 2. One end of the transmission belt 9 is sleeved on the crushing roller 2, and the other end of the transmission belt 9 is sleeved on the eccentric disc 10. A spring 13 is provided between the L-shaped block 11 and the feed hopper 4.
[0023] During the ore crushing process, the ore is fed into the inside of the feed hopper 4. The ore falls from the discharge port at the bottom of the feed hopper 4 between the two crushing rollers 2. The two crushing rollers 2 crush the ore. During the rotation of the crushing rollers 2, the eccentric disk 10 is driven to rotate through the transmission belt 9. During the rotation of the eccentric disk 10, the L-shaped block 11 is pushed upward. Multiple unblocking rods 8 will then move upward and insert into the inside of the feed hopper 4 to prevent the ore from being blocked at the discharge port of the feed hopper 4 due to mutual squeezing. When the eccentric disk 10 pushes the L-shaped block 11 to the highest point, the eccentric disk 10 continues to rotate. At this time, under the elastic force of the spring 13, the L-shaped block 11 moves downward. During the downward movement of the movable pressure rod 7, it can press down the ore on the two crushing rollers 2, enabling the ore to quickly enter between the two crushing rollers 2 for crushing. This can prevent the ore from moving on the crushing rollers 2 and not being able to quickly enter between the two crushing rollers 2 for crushing.
[0024] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
