[0035] Reference Figure 1-4 The present invention provides a dry pre-selection and waste disposal device for tungsten ore, including a fixed connecting seat 1, a pre-selection and waste disposal device body 2 installed on the top of the fixed connecting seat 1, an inspection door 3 hinged to the outside of the pre-selection and waste disposal device body 2, a feeding hopper 4 installed on the top of the pre-selection and waste disposal device body 2, an auxiliary pre-selection and waste disposal mechanism 5 installed on the top of the pre-selection and waste disposal device body 2, and a locking mechanism 6 provided on the outside of the pre-selection and waste disposal device body 2.

[0036] The auxiliary pre-selection waste disposal mechanism 5 includes a mounting base 51, a mounting shell 52 fixed to the top of the mounting base 51, a servo motor 53 mounted on the inner bottom wall of the mounting shell 52, a wear-resistant eccentric wheel 54 fixed to the outer side of the output shaft of the servo motor 53, a support frame 55 fixed to one side of the inner wall of the mounting base 51, a return spring 56 mounted on the side of the support frame 55 near the servo motor 53, a wear-resistant plate 57 connected to one end of the return spring 56, a guide post 58 fixed to one side of the wear-resistant plate 57, a support plate 59 fixed to one end of the guide post 58, and a feeding frame 510 fixed to the side of the support plate 59 away from the support frame 55. Both the mounting shell 52 and the feeding hopper 4 have internal openings. The limiting hole is adapted to the size of the feeding frame 510. When the feeding frame 510 moves in the horizontal direction, one end of the feeding frame 510 can move in the feeding hopper 4. The support frame 55 has a through hole inside, the size of which is adapted to the size of the guide column 58, so that the guide column 58 can drive the support plate 59 to move in the horizontal direction. The mounting base 51 is fixedly connected to the main body 2 of the pre-selected waste disposal device. The mounting shell 52 and the mounting base 51 are fixed with bolts to ensure a stable connection between the mounting shell 52 and the mounting base 51. The guide column 58 and the wear-resistant plate 57 are welded and fixed. One side of the wear-resistant plate 57 is in contact with the outer side of the wear-resistant eccentric wheel 54.

[0037] The locking mechanism 6 includes an anti-detachment guide sleeve 61, an anti-detachment slider 62 slidably connected to the anti-detachment guide sleeve 61 via a slide groove, a reinforcing baffle 63 fixed to the outside of the anti-detachment slider 62, a positioning threaded rod 64 fixed to the outside of the reinforcing baffle 63, a positioning nut 65 threadedly connected to the outside of the positioning threaded rod 64, a cast iron plate 66 fixed to the top of the inspection door 3, a limit sleeve 67 fixed to the outside of the cast iron plate 66, a groove provided inside the limit sleeve 67, the size of which is adapted to the size of the reinforcing baffle 63, the anti-detachment guide sleeve 61 and the pre-selected waste disposal device body 2 fixedly connected, and a connecting groove provided inside the limit sleeve 67 that is adapted to the size of the positioning threaded rod 64.

[0038] Working Principle: Tungsten ore is fed from the feed hopper 4 into the main body 2 of the pre-selection and waste disposal device, enabling the dry pre-selection and waste disposal process. During feeding, the servo motor 53 inside the mounting shell 52 is activated, causing the output shaft of the servo motor 53 to rotate the wear-resistant eccentric wheel 54. Each rotation of the wear-resistant eccentric wheel 54 pushes the wear-resistant plate 57 and guide column 58 to move, allowing the feeding frame 510 on one side of the support plate 59 to move horizontally within the feed hopper 4. The return spring 56 provides elasticity for reset, causing the feeding frame 510 to reciprocate within the feed hopper 4. This allows the feeding frame 510 to periodically impact the tungsten ore, effectively breaking up any lumps or agglomerates formed during transportation or storage. This ensures a uniform single-layer distribution of tungsten ore as it enters the sorting area, reducing the impact of large pieces or... This device addresses the issue of clumping leading to decreased sorting accuracy, thereby improving the identification accuracy of useful minerals and waste rock. It is equipped with a locking mechanism 6. When maintenance is required inside the pre-selection waste disposal device body 2 by opening the inspection door 3, the positioning nut 65 on the outside of the rotating positioning threaded rod 64 is removed. After removing the positioning nut 65, the anti-detachment slider 62 can be pulled horizontally, allowing one side of the anti-detachment slider 62 to slide within the groove of the anti-detachment guide sleeve 61. Furthermore, the anti-detachment slider 62 causes the reinforcing baffle 63 to disengage from the limiting sleeve 67, releasing the obstruction and limiting effect of the reinforcing baffle 63 on the outside of the cast iron plate 66. This facilitates the unlocking of the inspection door 3, allowing users to easily open the inspection door 3 for maintenance inside the pre-selection waste disposal device body 2, achieving the goal of easy maintenance for this device.

[0039] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
