Technical Field

[0001] The utility model relates to the technical field of crusher sorting, in particular to a sorting mechanism for a mining crusher. Background Art

[0002] Since the size of the mined rock minerals is large, the mining device will convey the mined rock minerals to the mining crusher through a preset belt to break the rock minerals into required granular sizes.

[0003] After the rock minerals are broken by the mining crusher, since there are magnetic particle minerals and non-magnetic particle minerals in the mineral broken particles, they need to be sorted out.

[0004] At present, for the existing sorting mechanism of magnetic particle minerals and non-magnetic particle minerals by a crusher, generally, a handheld magnetic device is held manually to perform magnetic sorting in a pile of granular minerals, which is prone to repeated magnetic sorting operations. Such manual magnetic sorting operations will greatly reduce the sorting efficiency of the mining crusher.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] Refer to Figures 1-5 , a sorting mechanism for a mining crusher, including a sorting conveyor belt 1. A fixing plate 3 is provided below the sorting conveyor belt 1. A bracket 2 is provided on the fixing plate 3. A crushing box 21 is provided on the bracket 2. A feed hopper 22 and a discharge pipe 23 are provided on the crushing box 21. A first sorting group 4 and a second sorting group 5 are provided on the fixing plate 3. A control box 24 is provided on the crushing box 21. A motor 10 and a belt 11 are provided on the sorting conveyor belt 1. A baffle strip 12 is provided on the belt 11. Both the first sorting group 4 and the second sorting group 5 are composed of a rotating motor 51, a cylinder 52, a top plate 53, an electromagnetic sorting block 54, and a sorting box 6. A caster 61 and a handle 62 are provided on the sorting box 6. A guiding and sliding expanding cavity 64 and a buffer pad 63 are provided inside the sorting box 6. A smooth layer 65 is provided on the inner wall of the guiding and sliding expanding cavity 64. The sorting conveyor belt 1 is a commonly used belt conveying device and is prior art.

[0027] A PLC is preset in the control box 24 to control the opening and closing of corresponding electric control devices.

[0028] The rotating motor 51 is arranged on the fixing plate 3. The cylinder 52 is arranged on the motor shaft of the rotating motor 51. The top plate 53 is arranged on the telescopic rod of the cylinder 52. The electromagnetic sorting block 54 is arranged at the lower end of the top plate 53. The electromagnetic sorting block 54 is a commonly used electromagnet. After being powered on and inserted into the minerals, it can effectively adsorb magnetic granular minerals and will not perform magnetic adsorption after power-off.

[0029] The longitudinal dimension of the top view of the electromagnetic sorting block 54 is not greater than the longitudinal dimension of the top view of the belt 11, ensuring that the lower end of the electromagnetic sorting block 54 can be fully inserted into the granular minerals on the belt 11.

[0030] The longitudinal dimension of the top view surface of the electromagnetic separation block 54 is not greater than the longitudinal dimension of the top view surface of the guiding and sliding cavity 64, ensuring that all the magnetic particle minerals adsorbed on the electromagnetic separation block 54 fall into the separation box 6.

[0031] Four symmetrically arranged casters 61 are provided at the lower end of the separation box 6, and a handle 62 is provided at the front end of the separation box 6. The casters 61 are universal moving wheels with a braking function.

[0032] There is a spacing between the lower end surface of the discharge pipe 23 and the upper end surface of the belt 11 to prevent friction and collision between the discharge pipe 23 and the belt 11.

[0033] There are two symmetrically arranged front and rear brackets 2, which are respectively fixedly arranged with the fixing plate 3 and the crushing box 21, improving the fixing stability of the crushing box 21.

[0034] The guiding and sliding cavity 64 is an upward-diffusing horn inner cavity structure, and a smooth layer 65 is evenly coated along the inner cavity wall of the guiding and sliding cavity 64. The smooth layer 65 is a graphite powder density coating layer with a flat and smooth surface and high durability.

[0035] There are two symmetrically arranged baffle strips 12, which are respectively arranged on the side wall surfaces of the belt 11. An anti-wear layer 121 is provided on the inner wall of the baffle strip 12. The anti-wear layer 121 is a tungsten carbide coating with excellent anti-wear performance, improving the durability of the baffle strip 12.

[0036] Working mode: A certain amount of mined minerals are put in through the feed hopper 22, and then the large-volume minerals are broken into particulate minerals by the symmetrically arranged crushing rolls preset in the crushing box 21 (prior art);

[0037] Next, start the control box 24. The PLC inside the control box 24 will control the opening of the discharge pipe 23 and at the same time control the operation of the motor 10. The granular minerals will fall onto the belt 11 through the discharge pipe 23. The granular minerals can be transported from left to right by the motor 10 and the belt 11. When the granular minerals are transported below the first sorting group 4, the PLC inside the control box 24 will control the shutdown of the motor 10 and start the cylinder 52 and the electromagnetic sorting block 54 on the first sorting group 4. The cylinder 52 will drive the electromagnetic sorting block 54 to move downward and insert it into the granular minerals to magnetically adsorb and sort out the magnetic granular minerals. Then, the PLC inside the control box 24 will control the startup of the motor 10 and reset the electromagnetic sorting block 54 on the first sorting group 4. The non-magnetic granular minerals will be transported from left to right again. When they are transported below the second sorting group 5, the PLC inside the control box 24 will control the shutdown of the motor 10 and start the cylinder 52 and the electromagnetic sorting block 54 on the second sorting group 5. The cylinder 52 will drive the electromagnetic sorting block 54 to move downward and insert it into the granular minerals to magnetically adsorb and sort out the missed magnetic granular minerals. Finally, the PLC inside the control box 24 will control the startup of the motor 10 again, transport the minerals without magnetic particles to the right end of the belt 11 and let them fall into the preset receiving box.

[0038] In the later stage, the PLC inside the control box 24 will control the startup of the rotating motors 51 of the first sorting group 4 and the second sorting group 5 to drive the top plate 53 and the electromagnetic sorting block 54 to rotate horizontally by 180 degrees and stop. Then the PLC will control the power-off of the electromagnetic sorting block 54. At this time, the magnetic granular minerals adsorbed on the electromagnetic sorting block 54 will fall downward into the sorting box 6.

[0039] The above can perform two electric-controlled magnetic separations on the granular minerals broken in the crushing box 21, and the sorted magnetic granular minerals are electrically controlled to rotate horizontally and fall into the corresponding sorting box 6, avoiding the manual operation of manually holding a handheld magnetic device to perform magnetic separation on a pile of granular minerals, thus avoiding repeated magnetic separation operations and improving the sorting efficiency of the mining crusher in magnetic separation operations.

[0040] Moreover, by setting the material blocking strip 12 structure on the belt 11, it is avoided that the broken granular minerals slide off from the side of the belt 11 during the magnetic separation transportation process, thus avoiding omission.

[0041] In addition, by setting the guide-sliding and expanding cavity 64 structure with a smooth layer 65 inside the sorting box 6, it is realized that the magnetic granular minerals sorted by magnetic separation fall into the sorting box 6 comprehensively and smoothly.

[0042] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
