The motor drives the rotating rod to rotate the stirring plate through the meshing of the second bevel gear and the first bevel gear, so that the stirring plate rotates counterclockwise to stir the ore, making the ore spread out and easier to screen. The screened ore is then transported and guided through the first guide opening and the second guide opening, respectively.

[0009] Preferably, the connecting frame is provided with a sliding groove at the corresponding position of the sliding block, and the sliding block slides in the sliding groove. The sliding block is limited in the sliding groove, so that it can only slide in the sliding groove, preventing it from coming off the sliding groove.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-4This utility model provides an embodiment of a high-efficiency screening device for mineral processing, comprising a connecting frame 1, a support leg 4, a first guide port 5 and a second guide port 6, and further comprising a slider 24, a rotating rod 26, a stirring plate 27 and a feeding mechanism. The support leg 4 is fixedly connected to the bottom of the connecting frame 1. The first guide port 5 and the second guide port 6 are fixedly connected inside the connecting frame 1. A feeding mechanism is provided inside the connecting frame 1. The slider 24 is slidably connected inside the connecting frame 1. The rotating rod 26 is rotatably connected inside the slider 24. The stirring plate 27 is fixedly connected to the outside of the rotating rod 26. The rotating rod 26 causes the stirring plate 27 to rotate and stir the falling ore. Ore is added into the conical opening 36 and concentrated into the feed inlet 31. The second spring 35 buffers the impact force of the ore on the conical opening 36. The motor 22 meshes with the first bevel gear 28 through the second bevel gear 29, causing the rotating rod 26 to drive the stirring plate 27 to rotate. This causes the stirring plate 27 to rotate counterclockwise to stir the ore, making it easier to screen. The screened ore is then conveyed and guided by the first guide port 5 and the second guide port 6 respectively. The connecting frame 1 has a groove at the corresponding position of the slider 24, and the slider 24 slides inside the groove. The groove limits the slider 24, ensuring that it can only slide inside the groove and preventing it from detaching from the groove.

[0024] Please see Figures 1-3 In this embodiment, a positioning block 21 is fixedly connected to the front of the connecting frame 1, a motor 22 is fixedly connected to the front of the connecting frame 1, a drive shaft 23 is fixedly connected to the output end of the motor 22, the drive shaft 23 is rotatably connected inside the positioning block 21, a first spring 25 is fixedly connected between the slider 24 and the connecting frame 1, a first bevel gear 28 is fixedly connected to the outside of the rotating rod 26, a second bevel gear 29 meshes with the outside of the first bevel gear 28, the second bevel gear 29 is rotatably connected inside the slider 24, the second bevel gear 29 is slidably connected to the outside of the drive shaft 23, a sieve plate 210 is fixedly connected inside the connecting frame 1, and the connecting frame 1 is fixedly connected to... A conveyor plate 211 is connected, and the two rotating rods 26 are driven by the drive shaft 23 to rotate synchronously and in the same direction, thereby stirring the ore at the same time. The drive shaft 23 has a groove at the corresponding position of the second bevel gear 29, and the drive shaft 23 slides inside the groove. The groove facilitates the drive shaft 23 to drive the second bevel gear 29 to rotate, and at the same time, it does not affect the second bevel gear 29 to slide with the slider 24. The slider 24 has a through hole at the corresponding position of the drive shaft 23, and the drive shaft 23 passes through the through hole. The drive shaft 23 passes through the through hole to facilitate the drive shaft 23 to drive the second bevel gear 29, and prevents it from affecting the sliding of the slider 24.

[0025] Please see Figure 1 , Figure 4In this embodiment, the feeding mechanism includes a feeding port 31, which is fixedly connected to the inside of the connecting frame 1. A positioning plate 32 is fixedly connected to the outside of the feeding port 31. A positioning rod 33 is fixedly connected to the top of the positioning plate 32. A movable cover 34 is slidably connected to the outside of the positioning rod 33. The movable cover 34 is slidably connected to the outside of the feeding port 31. A second spring 35 is fixedly connected between the movable cover 34 and the positioning plate 32. A conical opening 36 is fixedly connected to the top of the movable cover 34 to prevent damage to the conical opening 36 caused by the impact of falling ore, thus buffering the conical opening 36 and extending its service life. Four positioning rods 33 are provided, and the four positioning rods 33 are symmetrically fixedly connected to the top of the positioning plate 32. The movable cover 34 is symmetrically positioned by the four positioning rods 33 to prevent the movable cover 34 from shifting and to ensure smooth sliding of the movable cover 34.

[0026] During operation, ore is fed into the conical opening 36. The ore enters the feed inlet 31 through the conical opening 36. The impact of the ore on the conical opening 36 drives the movable cover 34. The movable cover 34 slides outside the positioning rod 33 and the feed inlet 31, while compressing the second spring 35. The second spring 35 absorbs the impact. Then, the ore enters the connecting frame 1 through the feed inlet 31 and falls onto the surface of the screen plate 210. As the connecting frame 1 tilts, the ore rolls down with the screen plate 210. Smaller pieces of ore pass through the screen plate 210 and fall onto the surface of the conveyor plate 211. At the same time, the motor 22 drives the drive shaft 23, which rotates inside the positioning block 21. The drive shaft 23 drives the second bevel gear 29, which in turn drives the first bevel gear 28. The first bevel gear 28 drives the rotating rod 26, which in turn drives the stirring plate 27. The stirring plate 27 stirs the ore, causing it to disperse and be screened. The ore impacts the stirring plate 27, which in turn drives the slider 24 via the rotating rod 26. The slider 24 compresses the first spring 25, which absorbs the impact. The slider 24 then drives the second bevel gear 29 to slide inside the groove of the drive shaft 23. The stirring plates 27 on both sides are arranged in an alternating pattern. The ore on the surface of the screen plate 210 and the conveying plate 211 is then discharged through the first guide port 5 and the second guide port 6, respectively.

[0027] Through the above steps, the motor 22 drives the stirring plate 27 to rotate counterclockwise, and in conjunction with the staggered arrangement of the stirring plates 27, the falling ore is stirred and fully contacted with the ore. This solves the problem that the stirring blades rotate in the same direction as the falling ore, which would result in the ore not being effectively stirred.
