Technical Field
[0001] This utility model relates to the field of ore sorting technology, specifically a portable ore sorting device for open-pit mines. Background Technology
[0002] In open-pit mining operations, ore sorting is a crucial step. Traditional ore sorting equipment is often bulky and complex, making it difficult to move and operate flexibly in the field. As mining operations gradually expand into remote and terrain-challenged areas, the demand for portable ore sorting equipment is becoming increasingly urgent.
[0003] In the prior art, utility model patent application number CN202421614616.3 discloses a tracked ore sorting machine, including a sorting bin, a vibrating screen inserted inside the sorting bin, a fixing plate fixedly connected to the outer wall of one side of the vibrating screen outside the sorting bin, a limit plate fixedly connected to one end of the outer wall of the fixing plate, a limit groove formed on the outer wall of the limit plate, and a quick-release mechanism for easy disassembly and assembly of the vibrating screen installed on one side of the outer wall of the sorting bin. This tracked ore sorting machine can perform vibration sorting of ore by using the vibrating screen in conjunction with the vibration of the vibrating motor. When the vibrating screen is used for screening for a long time, some ore particles will get stuck in the filter holes of the vibrating screen, causing blockage. At this time, the vibrating screen can be quickly disassembled through the quick-release mechanism, and the vibrating screen can be pulled out of the sorting bin for cleaning or replacement, and the vibrating screen can be quickly fixed and installed.

[0025] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:
[0026] Example 1
[0027] like Figure 1 and Figure 2 As shown, a portable ore sorting device for open-pit mines includes a sorting box 1, a support base 9, a shaking device 8, and casters 10. The sorting box 1 is mounted on the support base 9 via the shaking device 8. Inside the sorting box 1, a first screen plate 2, a first guide plate 3, a second screen plate 4, a second guide plate 5, a third screen plate 6, and a discharge plate 7 are arranged in an inclined manner from top to bottom. The first screen plate 2, the second screen plate 4, the third screen plate 6, and the discharge plate 7 are alternately inclined from left to right, and their lowest points all extend to the outside of the sorting box 1. The screen holes of the first screen plate 2, the second screen plate 4, and the third screen plate 6 decrease in size from top to bottom, thereby separating ores of different sizes. The first guide plate 3 is set at the same angle as the first screen plate 2, and the bottom of the first guide plate 3 is positioned above the top of the second screen plate 4, thereby guiding the ore screened from the first screen plate 2 onto the second screen plate 4 for a second screening. The second guide plate 5 is set at the same angle as the second screen plate 4; the second guide plate 5 is located above the third screen plate 6 and functions similarly to the second guide plate 5, guiding the ore onto the third screen plate 6. Anti-clogging devices 11 are provided on the lower end faces of the first screen plate 2, the second screen plate 4, and the third screen plate 6. The sorting box 1 includes a feed inlet 101, which is located on the upper end of the sorting box 1 above the first screen plate 2 and near the highest point. A caster wheel 10 is provided at the bottom of the support base 9. The caster wheel 10 facilitates the movement of the device.
[0028] like Figure 3 and Figure 4As shown, the shaking device 8 includes a mounting plate 801. A pair of shaking components are symmetrically arranged on the upper surface of the mounting plate 801, and a first motor 809 is arranged on the lower surface of the mounting plate 801. The pair of shaking components are driven by the first motor 809. The lower end of the sorting box 1 is fixedly arranged on the pair of shaking components. The shaking components include shaking rods 803, actuating elements 805, and rotating disks 807. The shaking rods 803 are all slidably arranged on the mounting plate 801 along their length direction. A push rod 808 is arranged at a non-central position on the upper surface of the rotating disk 807. The lower end is rotatably mounted on the mounting plate 801 and extends below the mounting plate 801, and is connected to the first motor 809. The actuating element 805 is rotatably mounted on the mounting plate 801 at its middle position and is located between the shaking rods 803 and the rotating disk 807. One end of the actuating element 805 is connected to the push rod 808, and the other end is connected to the shaking rod 803. The actuating element 805 has a strip-shaped actuating groove 806 at one end and a fan-shaped actuating tooth at the other end; the push rod 808 is slidably installed in the actuating groove 806; the rod body of the actuating element 805 has a tooth groove 804 that meshes with the actuating tooth. It also includes a power shaft 811, which is rotatably mounted on the lower end of the mounting plate 801; the lower ends of the rotating disks 807 in the pair of wobbling components both extend below the mounting plate 801 and are equipped with second bevel gears 812; a first bevel gear 810 is mounted on the output shaft of the first motor 809; and third bevel gears 813 are mounted on the power shaft 811 at positions corresponding to the first bevel gear 810 and the second bevel gear 812, meshing with each other. When the first motor 809 drives a pair of rotating disks 807 to rotate simultaneously via the power shaft 811, the rotating disks 807 can drive the actuating element 805 to swing left and right via the push rod 808 at the non-center position of the upper end face. When the actuating element 805 swings, it pushes the shaking rod 803 to swing left and right through the actuating teeth. The sorting box is installed on the shaking rod 803, so that it can swing left and right. The direction of its swing is perpendicular to the flow direction of the ore on the first screen plate 2, the second screen plate 4 and the third screen plate 6, so that the ore can slide down while also having a lateral swaying force, so that the ore can be evenly spread out.
[0029] like Figures 2-5As shown, a mounting base 102 is fixedly installed at the lower end of the sorting box 1. Fixing bolts 103 are provided on the side of the mounting base 102 corresponding to the end faces of each shaking rod 803, and the fixing bolts 103 are fixedly connected to the end faces of the shaking rods 803. The anti-blocking device 11 includes a first lead screw shaft 1101, a second lead screw shaft 1102, a linkage shaft 1103, a second motor 1104, and a bevel gear set 1105. The first lead screw shaft 1101, linkage shaft 1103, second lead screw shaft 1102, and second motor 1104 are sequentially connected by the bevel gear set 1105. The first lead screw shaft 1101 and the second lead screw shaft 1102 are arranged in parallel. A cleaning strip 1106 is movably arranged between the first lead screw shaft 1101 and the second lead screw shaft 1102. The upper end face of the cleaning strip 1106 abuts against the lower end face of the corresponding first screen plate 2, second screen plate 4, or third screen plate 6. The thickness of the first screen plate 2, the second screen plate 4, or the third screen plate 6 is selected to be relatively thin. Since the ore is generally blocky, selecting a thinner size ensures that when the ore is stuck in the filter holes, a portion of the lower end protrudes from the screen holes. When the cleaning strip 1106 reciprocates between the first lead screw shaft 1101 and the second lead screw shaft 1102, it abuts against the lower end face of the first screen plate 2, the second screen plate 4, or the third screen plate 6, thus pushing out the ore stuck in the screen holes. This ensures that the ore does not clog the screen plate and improves the screening effect.
