[0027] The aperture of the second screening net 7 is smaller than that of the first screening net 5, so that the filtering and screening assembly 2 can effectively screen the size of the ore powder particles. When the particle diameter of the ore powder is smaller than the aperture of the first screening net 5, the ore powder particles can pass through the first screening net 5 and fall on the surface of the second screening net 7. The particle size of the ore powder that does not pass through the first screening net 5 is the largest. When the ore powder that falls on the surface of the second screening net 7 passes through the second screening net 7, the ore powder can be discharged outward through the discharge plate 19 obliquely arranged on one side of the screening support 1. At this time, the particle size of the discharged ore powder is the smallest, and the particle size of the ore powder that does not pass through the second screening net 7 is medium.

[0028] The positioning slot 8 and the positioning plug 6 are in a plug-in fit, and the dismounting handle 11 and the embedded slot 10 are in a plug-in fit. The filtering and screening assembly 2 is designed to be in a plug-in fit between the positioning slot 8 and the positioning plug 6, so that the second screening plate 4 can be limited to be installed on the top of the first screening plate 3. The first screening plate 3 and the second screening plate 4 are designed to be in a plug-in fit between the dismounting handle 11 and the embedded slot 10, so that the first screening net 5 and the second screening net 7 can be respectively limited to be connected in the first screening plate 3 and the second screening plate 4. The outer end of the first screening plate 3 is connected with the hinged seat 12. The two sides of the first screening plate 3 away from the positioning slot 8 are provided with the guide sliding groove 13. The guide sliding groove 13 provided on the two sides of the first screening plate 3 can limit and guide the swing track of the filtering and screening assembly 2.

[0029] The driving motor 14 is installed at the bottom of one end of the screening support 1. The two groups of bearing seats 15 are connected at the top of the end of the screening support 1 close to the driving motor 14. The transmission wheel plates 16 are installed between the two groups of bearing seats 15 and the output end of the driving motor 14. The transmission belts 17 are connected between the two groups of transmission wheel plates 16. The transmission pull rods 18 are installed at the end of one group of bearing seats 15 away from the transmission wheel plates 16. The discharge plate 19 is obliquely arranged on the side of the screening support 1 close to the transmission pull rod 18. The groups of rollers 20 are respectively rotatably connected at the top of the two sides of the screening support 1. When the driving motor 14 installed at the bottom of one end of the screening support 1 is powered to operate, the filtering and screening assembly 2 can be driven to swing as a whole on the top of the screening support 1 through the transmission cooperation between the bearing seats 15, the transmission wheel plates 16, the transmission belts 17, the transmission pull rods 18 and other components. The end of the transmission pull rod 18 is hingedly connected with the hinged seat 12. The rollers 20 are in rolling contact with the guide sliding groove 13. The structure design of the rolling contact between the rollers 20 and the guide sliding groove 13 can increase the sliding of the bottom of the filtering and screening assembly 2 that swings on the top of the screening support 1, and can improve the flexibility of the swinging of the filtering and screening assembly 2 on the top of the screening support 1.

[0030] Working principle: This solution uses a filter screening component 2 installed on the top of the screening support 1. The filter screening component 2 is mainly composed of a first screening plate 3 and a second screening plate 4. The filter screening component 2 uses a structural design that allows the positioning slot 8 and the positioning rod 6 to be inserted and connected together, so that the second screening plate 4 can be limited and installed on the top of the first screening plate 3. The first screening plate 3 and the second screening plate 4 use a structural design that allows the first screening screen 5 and the second screening screen 7 to be limited and connected to the inside of the second screening plate 4 and the first screening plate 3, respectively.

[0031] This solution utilizes a hinged connection between one end of the transmission rod 18 and the hinge seat 12. When the drive motor 14 installed at the bottom of one end of the screening bracket 1 is powered on, the transmission between components such as the bearing seat 15, transmission wheel 16, transmission belt 17, and transmission rod 18 drives the entire filter screening assembly 2 to sway at the top of the screening bracket 1. The rolling contact between the roller 20 and the guide groove 13 provides increased lubrication to both sides of the bottom of the swaying filter screening assembly 2 at the top of the screening bracket 1, and also improves the flexibility of the swaying of the filter screening assembly 2 at the top of the screening bracket 1. At the same time, it also limits and guides the swaying trajectory of the filter screening assembly 2, effectively improving the stability of the filter screening assembly 2 in the screening of mineral powder.

[0032] In this scheme, the aperture of the second screening mesh 7 is smaller than that of the first screening mesh 5. When the particle diameter of the mineral powder is smaller than that of the first screening mesh 5, it can pass through the first screening mesh 5 and fall onto the surface of the second screening mesh 7. The mineral powder particles that do not pass through the first screening mesh 5 are the largest. When the mineral powder that falls onto the surface of the second screening mesh 7 passes through the second screening mesh 7, it can be discharged outward through the discharge plate 19 installed at an incline on one side of the screening support 1. At this time, the discharged mineral powder particles are the smallest, while the mineral powder particles that do not pass through the second screening mesh 7 are medium. Through the above means, the mineral powder particles can be screened into three types: large, medium, and small, to facilitate subsequent processing.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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.
