Description

Technical Field

[0001] The present invention relates to the technical field of ore crushing, and specifically provides an ore crushing device capable of uniform screening. Background Art

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which itself has certain utilizable properties, and can be divided into metallic minerals and non-metallic minerals. The unit content of useful components (elements or minerals) in ore is called ore grade. Precious metal ores such as gold and platinum are expressed in grams per ton, and other ores are commonly expressed as percentages. Ore grade is commonly used to measure the value of ore, but the composition of gangue (useless minerals in ore or minerals with extremely low content of useful components and cannot be utilized) and the amount of harmful impurities in ores with the same effective components also affect the ore value.

[0003] In the prior art, in order to facilitate the transportation of ore, it is necessary to crush the ore. After the existing crushing device continuously crushes the ore, when the ore is discharged, if too much ore is discharged at one time, it may cause the discharge port to be blocked, resulting in the inability to discharge the crushed ore from the discharge port, which may affect the normal use of the device.

Two groups of crushing rollers 12 are rotatably installed inside the crushing box 11. The ore is crushed by the crushing rollers 12 inside the crushing box 11 to facilitate the transportation of the ore;

[0028] Exemplarily, a transmission mechanism 2 is further provided inside the blanking box 1. The transmission mechanism 2 includes two groups of movable rods 21 longitudinally arranged inside the blanking box 1 and capable of moving up and down. The two groups of movable rods 21 are respectively located at both ends of the crushing roller 12. Square collar rings 211 are fixedly connected to both ends of one group of movable rods 21, and U-shaped rods 22 are movably sleeved on the inner walls of the two groups of square collar rings 211; first gears 25 and second gears 26 that mesh with each other are installed on the shaft rods at the same end of the two groups of crushing rollers 12. One end of the U-shaped rod 22 located at the upper end of the movable rod 21 is fixed to the first gear 25, and the other end of the U-shaped rod 22 located at the upper end of the movable rod 21 is rotatably installed on the crushing box 11. The U-shaped rod 22 can drive the first gear 25 to rotate, and the first gear 25 drives the second gear 26 to rotate, so that power can be provided to the crushing roller 12 through the first gear 25 and the second gear 26.

[0029] Exemplarily, two groups of inclined sieve plates 28 are provided inside the blanking box 1. The high ends of the two groups of sieve plates 28 are both hinged to the blanking box 1, and the ore can be screened through the sieve plates 28;

[0030] Exemplarily, two groups of fixing rods 27 are fixedly connected to the outer walls of the two groups of movable rods 21. Limiting grooves 281 are opened on both sides of the two groups of sieve plates 28, and the ends of the two groups of fixing rods 27 far from the movable rods 21 are respectively movably sleeved in the limiting grooves 281 on the two sieve plates 28. Through the mutual cooperation of the square collar ring 211 and the U-shaped rod 22, when the U-shaped rod 22 rotates, it drives the movable rod 21 to move up and down, and the movable rod 21 cooperates with the fixing rod 27 to drive the sieve plate 28 to rotate, so as to facilitate driving the ore on the sieve plate 28 to shake, and to a certain extent, prevent the ore from being blocked during blanking.

[0031] Refer to Figure 1 and Figure 3 It can be known that a connecting plate is fixedly connected to the top end of the blanking box 1, and a motor 24 is installed on the connecting plate. The output end of the motor 24 is connected to one group of U-shaped rods 22 through a coupling. By driving one group of U-shaped rods 22 to rotate through the motor 24, power can be provided to the crushing roller 12 through the first gear 25 and the second gear 26.

[0032] Refer to Figures 1 - 4 It can be known that inclined plates 29 fixedly connected to the inner wall of the blanking box 1 are provided below the two groups of sieve plates 28, and the high ends of the inclined plates 29 correspond to the low ends of the sieve plates 28. Through the arrangement of the inclined plates 29, the debris screened by the sieve plates 28 can be conveyed, so as to facilitate the collection of the debris and prevent waste.

[0033] Exemplarily,

[0034] Refer to Figure 2 、 Figure 3 、 Figure 4 、 Figure 6It can be seen that a transmission rod 23 is movably arranged between the two groups of movable rods 21 below the inclined plate 29, and a square collar 211 is also installed at the lower end of the movable rod 21 far from the first gear 25. A U-shaped rod 22 is also installed in the square collars 211 at the lower ends of the two movable rods 21. Both ends of the transmission rod 23 are fixedly connected to the U-shaped rods 22 at the lower ends of the two movable rods 21 respectively, and the U-shaped rods 22 at the lower ends of the two movable rods 21 are rotatably installed on the blanking box 1. Through the arrangement of the transmission rod 23, the two groups of movable rods 21 can be lifted and lowered simultaneously, thereby driving the sieve plate 28 to vibrate and screening the ore.

[0035] Exemplarily, the upper end of the movable rod 21 far from the first gear 25 extends to the outer wall of the blanking box 1, and a limiting cylinder 13 matching the outer wall of the blanking box 1 is provided at the upper end of the movable rod 21 far from the first gear 25. Through the arrangement of the limiting cylinder 13, a group of movable rods 21 can be limited.

[0036] Refer to Figure 3 It can be seen that two groups of fixing plates 17 are longitudinally fixedly connected to both sides of the sieve plate 28 on the inner wall of the blanking box 1. Through the arrangement of the fixing plates 17, the ore and the transmission mechanism 2 can be separated, thereby protecting the transmission mechanism 2;

[0037] Exemplarily, through grooves 171 are formed on the surfaces of the two groups of fixing plates 17, and the middle parts of the two groups of fixing rods 27 penetrate through the through grooves 171. Through the arrangement of the through grooves 171, the fixing rods 27 can be limited in the front and back directions.

[0038] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 It can be seen that openings 15 are formed on both side surfaces of the blanking box 1, and the lower ends of the two inclined plates 29 are respectively butted against the two openings 15; mounting plates 16 respectively butted against the two openings 15 are further provided on the outer wall of the blanking box 1, and a collection box 161 is movably installed in the mounting plates 16. Through the arrangement of the openings 15, the debris conveyed on the inclined plates 29 can be collected through the collection box 161, preventing waste of raw materials.

[0039] Refer to Figure 5 It can be seen that dovetail blocks 162 are fixedly connected to both outer walls of the collection box 161, and dovetail grooves 163 matching the dovetail blocks 162 are formed on the inner wall of the mounting plate 16. Through the mutual cooperation of the dovetail blocks 162 and the dovetail grooves 163, the collection box 161 can be limited.

[0040] Exemplarily, a guide plate 18 is also inclined at the bottom of the blanking box 1. The high end of the guide plate 18 is docked with the low end of the lower sieve plate 28. An outlet 14 is provided on the blanking box 1. The low end of the guide plate 18 is docked with the outlet 14, and a conveyor belt 19 is provided on one side of the blanking box 1. The conveying surface of the conveyor belt 19 is docked with the outlet 14. Through the mutual cooperation of the guide plate 18 and the outlet 14, the ore can be discharged onto the surface of the conveyor belt 19 for transportation.

[0041] The working principle of the present invention is as follows: By inputting the ore into the crushing box 11, starting the motor 24, the motor 24 drives a group of U-shaped rods 22 to rotate. The U-shaped rods 22 drive the first gear 25 to rotate, and the first gear 25 drives the second gear 26 to rotate, so as to simultaneously drive the two crushing rolls 12 to rotate and crush the ore.

[0042] Furthermore, through the arrangement of the square sleeve ring 211 and the U-shaped rod 22, the movable rod 21 moves up and down. The movable rod 21 cooperates with the fixed rod 27 to drive the sieve plate 28 to vibrate, so as to screen the crushed ore. The ore vibrates and discharges under the action of the sieve plate 28, thus preventing the outlet from being blocked due to excessive one-time discharging.

[0043] Still further, the fine ore debris falls onto the inclined plate 29 after screening. The debris falling on the inclined plate 29 is transmitted to the inside of the collection box 161 through the opening 15 for collection. The larger pieces of ore remaining on the sieve plate 28 are guided by the guide plate 18, discharged through the outlet 14 onto the surface of the conveyor belt 19, and the ore is transported by the conveyor belt 19. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0044] Although the embodiments of the present invention have been shown and described, this specific embodiment is only an explanation of the present invention, and it is not a limitation of the utility model. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations without creative contributions to the embodiments according to needs, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
