[0017] The utility model will be described in detail below with reference to the drawings and in combination with the embodiments. It should be noted that, without conflict, the embodiments in the utility model and the features in the embodiments can be combined with each other.

[0018] Such as Figures 1 to 4In the embodiment of the lead concentrate screening device of the present utility model shown, the lead concentrate screening device includes a frame body 1 and a bottom frame 2. A vibration motor 3 is fixedly installed at the bottom of the frame body 1. The four corners of the bottom frame 2 are respectively fixedly connected to the lower side of the frame body 1 through vibration sieve springs 4. A surrounding frame 5 is connected to the inner side of the frame body 1 by bolts. A screen 6 which is inclined is fixedly connected to the bottom of the surrounding frame 5. A feed frame 7 is fixedly installed on one side of the frame body 1. A plurality of support rods 8 are fixed on the upper side of the bottom frame 2. A protective cover 9 is connected to the tops of the plurality of support rods 8 by bolts. A top seat 10 is provided in the middle of the protective cover 9. A reciprocating lead screw 11 is rotatably connected in the top seat 10. A slider is provided on the reciprocating lead screw 11. A strip-shaped groove is formed in the middle of the protective cover 9. A moving block 12 is slidably connected in the strip-shaped groove. The upper side of the moving block 12 is fixedly connected to the slider. A sleeve seat 13 which can move up and down is sleeved on the bottom of the moving block 12. A support rod 14 is fixedly connected to the bottom of the sleeve seat 13. A plurality of diamond-shaped dial rods 15 are fixed to the lower side of the support rod 14. By putting the crushed lead ore materials into the device through the feed frame 7, the frame body 1, the surrounding frame 5 and the screen 6 vibrate under the action of the vibration motor 3, and the screen 6 is inclined, so that the materials put into through the feed frame 7 can move to the lower side of the screen 6 during the screening process. The small-particle materials enter the inside of the frame body 1 through the screen 6 and slide out along the inclined surface of the inner bottom wall of the frame body 1, while the large-particle materials move to the lower side of the screen 6. The protective cover 9 plays a role in preventing the materials on the screen 6 from splashing out during the vibrating screening. The rotation of the reciprocating lead screw 11 can drive the sleeve seat 13 and the dial rods 15 to move back and forth above the screen 6, so as to play a role in dialing the materials and prevent the materials from accumulating on the screen 6. The reciprocating lead screw 11 is a kind of lead screw that can make the slider perform reciprocating motion without changing the rotation direction of the main shaft.

[0019] In an embodiment of the present application, preferably, a first discharge port is fixedly installed at the lower side of the screen 6. The inner bottom wall of the frame body 1 is an inclined surface. A second discharge port is fixedly installed on the side of the frame body 1 away from the feed frame 7. The second discharge port is located below the first discharge port. The large-particle materials are discharged through the first discharge port, while the small-particle materials are discharged through the second discharge port. The outlets of the first discharge port and the second discharge port are arranged staggeredly, so as to facilitate receiving materials separately.

[0020] In an embodiment of the present application, preferably, a driving motor 16 is installed on the protective cover 9 by bolts. The output end of the driving motor 16 is fixedly connected to one end of the reciprocating lead screw 11. By starting the driving motor 16, the reciprocating lead screw 11 can be driven to rotate.

[0021] In an embodiment of the present application, preferably, a positioning seat 17 is fixed to the lower side of the protective cover 9. An inclined slot 18 is formed in the positioning seat 17. The included angle between the inclined slot 18 and the horizontal plane is smaller than the included angle between the screen 6 and the horizontal plane. A plug 19 is fixed to the side surface of the socket 13. The plug 19 is slidably connected to the corresponding inclined slot 18, so that the socket 13 can drive the dial rod 15 to reciprocate along the inclined slot 18. And because the included angle between the inclined slot 18 and the horizontal plane is smaller than the included angle between the screen 6 and the horizontal plane, the dial rod 15 never contacts the screen 6.

[0022] In an embodiment of the present application, preferably, a connecting rod 20 is fixed to one side of the support rod 14. One end of the connecting rod 20 can extend below the feed frame 7 and is fixed with a V-shaped rod 21. The material below the feed frame 7 can be stirred by the V-shaped rod 21 to avoid material accumulation.

[0023] In an embodiment of the present application, preferably, a gap is left between the protective cover 9 and the frame body 1, and a gap is left between the plurality of support rods 8 and the frame body 1. The vibration of the frame body 1 can avoid collision or influence on the protective cover 9, and further avoid the collision between the V-shaped rod 21 and the dial rod 15 and the screen 6.

[0024] When the present utility model is in use, the crushed lead ore material is put into the device through the feed frame 7. The frame body 1, the surrounding frame 5 and the screen 6 vibrate under the action of the vibration motor 3, and the screen 6 is inclined, so that the material put into through the feed frame 7 can move to the lower side of the screen 6 during the screening process. The small-particle material enters the interior of the frame body 1 through the screen 6 and slides out along the inclined surface of the inner bottom wall of the frame body 1, while the large-particle material moves to the lower side of the screen 6. The protective cover 9 functions to prevent the material on the screen 6 from splashing out during the vibrating screening. The rotation of the reciprocating screw rod 11 can drive the socket 13 and the dial rod 15 to reciprocate above the screen 6, thereby playing a role in stirring the material and avoiding material accumulation on the screen 6. The V-shaped rod 21 can stir the material below the feed frame 7 to avoid material accumulation.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. And these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
