Technical Field

[0001] The invention relates to a mining classification device, belonging to the technical field of mining. Background Art

[0002] Since the ore is ground by the mill, the ore particle size varies greatly, and the existing mining grading devices mostly only screen into large ore blocks and fine ore particles, and the accuracy and grading effect are not obvious. In addition, the existing grading devices are mostly screen plate screening devices. Due to the diversity of particle size, it is inevitable that the screen plate will be blocked, which not only affects the life of the machine, but also affects the screening efficiency. More blockages will also affect the screening quality.

[0003] Therefore, Chinese patent publication number CN210675863U discloses a mining grading device, which can perform four-stage screening on stones by setting multiple screening cylinders with different inner diameters, thereby increasing the screening efficiency. However, due to the different sizes of ore blocks, some ores may get stuck in the gaps between the screening cylinders, affecting normal use and posing a safety hazard. Therefore, a mining grading device is urgently needed to solve the above-mentioned problems. Summary of the invention

The left side of the screening box body is connected to the brake box, and a plurality of rotating motors are arranged inside the brake box. A movable groove is also provided at the rotating motor position on the side of the brake box. The top of the screening box body is provided with a feed port, and a spacer is installed at the top of the inner top of the screening box body and connected to the feed port. Three layers of interception plates are arranged inside the screening box body, and the position of each layer of interception plates is A screening cylinder is provided, wherein the first screening cylinder is provided at the top layer, the second screening cylinder is provided at the middle part, the third screening cylinder is provided at the lowest layer, and guide blocks are installed on the surfaces of the plurality of screening cylinders. The right side of the screening box body is provided with a plurality of discharge ports, and a screening frame is added outside the discharge port.

The right side of the screening box body 1 is provided with multiple discharge ports 8, and a screening frame 9 is added outside the discharge port 8. The adjustment component 6 includes a mounting shaft 61, a connecting port 62, a fixed plate 63, an auxiliary extension block 64 and a movable bolt 65. The connecting port 62 inside the mounting shaft 61 is installed together with the connecting bearings 15 on the first screening drum 10, the second screening drum 11 and the third screening drum 12, and auxiliary extension blocks 64 are arranged at the upper and lower ends of the mounting shaft 61. The auxiliary extension block 64 is arranged on the fixed plate 63, and the mounting shaft 61 is fixed in the auxiliary extension block 64 by a movable bolt 65.

[0015] As a first embodiment of the present invention: the first screening drum 10, the second screening drum 11 and the third screening drum 12 are all provided with connecting bearings 15 at both ends, and the first screening drum 10, the second screening drum 11 and the third screening drum 12 are all of different sizes. The design sets screening drums of different sizes, which is helpful to grade and screen out ores of different sizes and transport them out to achieve efficient screening. The multi-layer interception plates 13 are welded on the inner wall of the screening box body 1 at equal distances. The design adds interception plates 13 on each layer of screening drum, which is helpful to intercept the ores from the upper layer. The ore falls from the layer screening drum, the size of the movable groove 5 on the side of the brake box 3 matches the corresponding screening drum specifications. The design of the movable groove 5 helps to facilitate the range swing of the screening drum during operation to prevent small particles of ore from getting stuck in the screening drum.

Similarly, rocks with slightly smaller particle sizes fall onto the second screening drum 11, and the rock blocks are further screened. Rocks with smaller particle sizes on the second screening drum 11 will fall onto the third screening drum 12 for third-level screening. These screened rocks will fall into the screening frame 9 outside the corresponding discharge port 8. When the first screening drum 10, the second screening drum 11 and the third screening drum 12 roll, the corresponding rotating motor 4 will swing within the range of the movable groove 5, and the connecting bearing 15 on the right side of the screening drum will deviate left and right under the fixing action of the movable bolt 65, so that part of the ore will not get stuck in the screening drum and affect normal screening.
