Description

Technical Field

[0001] The utility model belongs to the technical field of gravel sorting, and in particular relates to a mining gravel sorting device. Background Art

[0002] The mining industry is an important raw material industry. Metal ores are the main raw materials for the smelting industry, and non-metallic ores are important chemical raw materials and building materials. However, the ores obtained in the mining process vary in size and need to be sorted. In order to save time, workers use sorting equipment to sort the crushed stones.

[0003] At present, the common sorting devices for mining gravel usually use screens or sieve rods to perform multi-stage sorting of gravel. For example, Patent No. CN202121723916.1 discloses an efficient and energy-saving gravel sorting equipment for mining, in which multiple groups of perforated plates with different specifications are provided to perform multi-stage sorting of gravel. Although the sorting specifications of gravel can be increased by cooperating with multiple groups of perforated plates, it mainly relies on increasing the number of perforated plates to increase the sorting specifications. When the number of perforated plates is fixed, the specifications for sorting gravel are still very limited and cannot meet the requirements of fine sorting of gravel. In addition, since the sorting holes on the perforated plates are used to sort gravel, during the sorting process, gravel is very easy to get stuck in the sorting holes of the perforated plates, causing the perforated plates to fail. There is also a lack of a mechanism for cleaning the perforated plates. When the perforated plates are blocked, the machine needs to be stopped for manual cleaning, which is cumbersome and inefficient.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies.

[0005] Therefore, in order to solve the above problems, the utility model provides a mining gravel sorting device. Utility Model Content

[0006] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide a mining gravel sorting device, which can perform multiple sorting operations on gravel through two groups of screening plates. If the leakage holes on the screening plate are blocked by some gravel, affecting its sorting effect, the screening plate can be driven to rotate 180° by the flipping assembly. Due to the flipping of the screening plate, some of the gravel stuck in its leakage holes can automatically fall off due to the action of gravity, and some of the gravel that cannot fall automatically can be shaken off by the shaking of the screening plate, thereby achieving the effect of cleaning the gravel blocked in the leakage holes. In addition, the screening plate can still continue to perform screening operations after flipping, thereby reducing downtime and improving sorting efficiency.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0008] The screening machine is a kind of mining crushed stone sorting device, comprising a base frame, the base frame is equipped with a sorting box, and two groups of screening plates are installed inside the sorting box, and a turning assembly is installed on the sorting box for rotating and turning the two groups of screening plates, so as to ensure the stability of the screening plates during the screening process. The two groups of screening plates can be used to sort the crushed stones for multiple times, and if the leakage holes on the screening plates are blocked by some crushed stones, affecting the sorting effect, the screening plates can be driven to rotate 180 degrees by the turning assembly, and due to the turning of the screening plates, some crushed stones stuck in the leakage holes can automatically fall off by the action of gravity, and some crushed stones that cannot automatically fall off can be shaken off by the shaking of the screening plates, thereby achieving the effect of cleaning the crushed stones blocked in the leakage holes. In addition, the screening plates can continue to perform screening operations after being turned over, thereby reducing downtime and improving sorting efficiency.

[0009] Furthermore, the sieve plates are all provided with leakage holes, and the apertures of the leakage holes on the upper group of sieve plates are larger than the apertures of the leakage holes on the lower group of sieve plates.

[0010] Furthermore, the flipping assembly includes a motor base fixedly mounted on the outer wall of the sorting box, a servo motor is mounted on the top of the motor base, a connecting base is mounted on the bottom ends of the two groups of screening plates, a rotating rod is connected through the connecting base, the output end of the servo motor is connected to one end of one group of the rotating rods, pulleys are mounted on the two groups of rotating rods, and the two groups of pulleys are connected by belt transmission.

[0011] Furthermore, two groups of limiting holes are provided on both sides of the sorting box, and the limiting holes are arranged below the screening plates at corresponding positions.

[0012] Furthermore, the limiting assembly includes a mounting frame fixedly mounted on the outer wall of the sorting box, a spring is mounted on the inner side of the mounting frame, a movable frame is mounted on one end of the spring, a limiting plate is mounted on one side of the movable frame, and a pull handle is mounted on the other side of the movable frame.

[0014] Furthermore, a plurality of discharge ports are provided on one side of the sorting box.

[0015] Furthermore, a vibration motor is installed at the bottom end of the sorting box, and a plurality of supporting springs are installed on both sides of the sorting box.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the utility model, the vibration motor drives the entire sorting box to vibrate, and the crushed stones are put into the upper screening plate. After vibration, the crushed stones smaller than the leakage holes on the upper screening plate fall onto the lower screening plate, and the crushed stones smaller than the leakage holes on the lower screening plate fall onto the inner bottom surface of the sorting box. The screened crushed stones are discharged through the discharge port at the corresponding position. If the leakage holes on the screening plate are blocked by some crushed stones, affecting the sorting effect, first pull the pull handle, the pull handle drives the movable frame to move outward, and the movable frame drives the limit plate to move outward, thereby causing the limit plate to move away from the bottom of the screening plate, and then start the servo motor, which drives one set of rotating rods to rotate. Another set of rotating rods is driven to rotate by the action of the pulley and the belt, and the rotation of the rotating rods drives the rotation of the screening plate, and the screening plate rotates 180° to realize the flipping of the screening plate. After the screening plate is flipped over, the pull handle is released, and the limit plate is reset by the action of the spring restoring force, and then extends to the bottom of the screening plate to limit the screening plate. The gravel stuck in the leakage hole of the flipped part of the screening plate can automatically fall off by the action of gravity, and some gravel that cannot fall automatically can be shaken off by the shaking of the screening plate, thereby achieving the effect of clearing the gravel blocked in the leakage hole. In addition, the screening plate can still continue to perform screening operations after flipping, which can reduce downtime and improve sorting efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

If the screening plates 3 are If the leakage holes are blocked by some gravel, affecting the sorting effect, the screen plate 3 can be driven to rotate 180° by the flipping component 4. Due to the flipping of the screen plate 3, some of the gravel stuck in the leakage holes can fall down automatically by the action of gravity, and some of the gravel that cannot fall down automatically can be shaken down by the shaking of the screen plate 3, thereby achieving the effect of clearing the gravel blocked in the leakage holes. In addition, the flipped screen plate 3 can still continue the screening operation, thereby reducing downtime and improving sorting efficiency.

[0026] The sieve plates 3 are all provided with leakage holes, and the aperture of the leakage holes on the upper group of sieve plates 3 is larger than the aperture of the leakage holes on the lower group of sieve plates 3.
