Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of screening, in particular to a screen for ore screening. Background Art
[0002] After mining, the ore needs to be crushed, and the crushed ore needs to be screened to classify ores of different sizes. Screens are needed for ore screening. For example, a gold ore screening machine (patent number: CN202120186347.5) disclosed in Chinese patent literature has upper, middle and lower three-layer screens for screening the ore. The three layers of screen frames are connected by springs. Although the screen frame vibrates up and down through the cam under the action of the spring, there is no other connection structure between the three layers of screen frames. Since the spring itself has elastic force, it cannot play a stable supporting role, and the three groups of screen frames are connected by springs. The vibration generated under the action of the cam will make the device more unstable, and the screens are all placed horizontally. The screened ore cannot automatically detach from the screen, which will reduce the efficiency of the screen in screening ore.
[0003] For this purpose, we propose a screen for ore screening. Utility Model Content

A mounting hole 13 is provided on the surface of the side opposite to the right of the first mounting frame 1 and the second mounting frame 2, and a mounting shaft 14 is provided in the mounting hole 13. The right end of the screen fixing frame 3 is fixedly connected to the mounting shaft 14. A hopper 16 is provided on the upper part of the first mounting frame 1 to screen the crushed ore. The crushed ore is put into the hopper 16, and the ore slides down along the hopper 16 to the left side of the top of the screen 4. At the same time, the reduction motor 8 is started, and the reduction motor 8 drives the cam The wheel 9 rotates, and during the rotation of the cam 9, when the protruding part of the cam rotates to the right side of the reduction motor 8, it will contact the bottom of the fixed rod 6 and lift up the fixed rod 6, and the fixed rod 6 drives the push rod 5 to move upward. The push rod 5, the screen fixing frame 3 and the screen are all provided with three groups. The three groups of push rods 5 will push the left ends of the three groups of screen fixing frames 3 to move upward, and the right ends of the three groups of screen fixing frames 3 rotate through the installation shaft 14. When the protruding part of the cam 9 is separated from the bottom of the fixed rod 6, the fixed rod 6 moves downward under gravity, and the screen fixing frame 3 and the screen 4 move downward at the same time, and the fixed rod 6 is continuously lifted up by the cam 9, so that The screen fixing frame 3 and the screen continuously move up and down to form vibration, so as to screen the crushed ore. The three groups of screens 4 screen at the same time, and the crushed ore is finely screened. A buffer plate 41 is arranged in the middle of the uppermost screen 4. The ore slides onto the upper screen 4 after passing through the hopper 16, and the ore falls relatively concentratedly. The screen 4 is tilted, and the ore slides to the right. The buffer plate 41 buffers the sliding speed of the sliding ore, and increases the residence time of the ore on the surface of the uppermost screen 4, so as to ensure that all ores of the same size are screened out, and avoid the ore not being screened out due to excessive sliding speed.
[0019] Among them, a guide plate 15 is arranged on the right side of the first mounting frame 1. The guide plates 15 are arranged in three groups. The lengths of the three groups of guide plates 15 decrease from top to bottom. The length of the upper guide plate 15 is the longest, and the length of the bottom guide plate is the shortest. When the three groups of screens screen out ores of different sizes for collection, three collection boxes of different heights will be used for collection. The heights of the three collection boxes will just be able to be placed at the bottom of the right end of the three groups of guide plates 15 in turn, so that the ores of different sizes screened out can be collected in an orderly manner;
[0020] The push rod 5 is fixedly connected to the support rod 12, and the support rod 12 is slidably connected to the inner wall of the slide groove 11. The support rod 12 supports the push rod 5 and limits the moving direction of the push rod 5, so that the push rod 5 can only move up and down;
[0021] The screen fixing frame 3 and the screen 4 are both provided with three groups, and a buffer plate 41 is provided in the middle of the top screen 4. The diameters of the screen holes on the three groups of screens 4 decrease from top to bottom. The three groups of screens with different diameters of screen holes are arranged in descending order, and the size of the ore is screened in descending order at the same time, thereby accelerating the screening efficiency of the ore.
[0022] The left end of the push rod 5 is fixedly connected to the fixing rod 6, and the right end of the push rod 5 is at the bottom of the screen fixing frame 3. The bottom end of the fixing rod 6 is provided with an arc. Driven by the fixing rod 6, the push rod 5 can push the left end of the screen fixing frame 3 to move upward.
[0023] Working principle: the crushed ore is screened and put into the hopper 16. The ore slides down along the hopper 16 to the left side of the top of the screen 4. At the same time, the reduction motor 8 is started, and the reduction motor 8 drives the cam 9 to rotate. During the rotation of the cam 9, when the protruding part of the cam rotates to the right side of the reduction motor 8, it will contact the bottom of the fixed rod 6 and lift the fixed rod 6. The fixed rod 6 drives the push rod 5 to move upward. The push rod 5, the screen fixing frame 3 and the screen are all provided with three groups. The three groups of push rods 5 will push the left ends of the three groups of screen fixing frames 3 to move upward. The right ends of the three groups of screen fixing frames 3 rotate through the installation shaft 14. When the protruding part of the cam 9 is separated from the bottom of the fixed rod 6, the fixed rod 6 is subjected to gravity. The cam 9 continuously lifts the fixing rod 6, so that the screen fixing frame 3 and the screen continuously move up and down to form vibration, so as to screen the crushed ore. The three groups of screens 4 are screened at the same time, and the crushed ore is finely screened. A buffer plate 41 is arranged in the middle of the uppermost screen 4, and the ore slides onto the upper screen 4 after passing through the hopper 16. The ore falls relatively concentratedly. The screen 4 is tilted, and the ore slides to the right. The buffer plate 41 buffers the sliding speed of the sliding ore, increases the residence time of the ore on the surface of the uppermost screen 4, and ensures that all ores of the same size are screened out to avoid the ore not being screened out due to excessive sliding speed.
[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
