Description

Technical Field

[0001] This utility model relates to the field of raw ore processing technology, specifically a crushing device for raw ore processing. Background Technology

[0002] Ore mined from a mine that has not undergone beneficiation or other technical processing can be used directly in some cases, but most ore needs to beneficiation or other technical processing before it can be used. In beneficiation, the ore that has been crushed and ground before entering the sorting operation is called the beneficiated ore.

[0003] Existing raw ore crushing devices lack screening measures for oversized ores. When oversized ores enter the crushing device, they may remain positioned above the two crushing rollers, unable to be squeezed by them, thus affecting the overall crushing efficiency. Furthermore, crushing oversized ores also shortens the service life of the crushing rollers. Therefore, a raw ore crushing device is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a crushing device for raw ore processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a crushing device for raw ore processing, comprising a crushing box, a support frame fixedly installed at the bottom of the crushing box, two crushing rollers rotatably installed inside the crushing box, a driving mechanism acting on the crushing rollers provided on the outer wall of the crushing box, a guide plate fixedly installed at the upper end of the crushing box, a U-shaped frame provided above the guide plate, the bottom two sides of the U-shaped frame being fixedly connected to the support frame via fixed plates, an intercepting grid provided inside the U-shaped frame, one end of the intercepting grid being rotatably connected to the U-shaped frame via a rotating shaft, and a vibration mechanism acting on the swing end of the intercepting grid provided on the fixed plate, the vibration mechanism consisting of a fixed rod, a cam, a second motor, and a second support plate.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a crushing device for raw ore processing includes a crushing box 1. A support frame 2 is fixedly installed at the bottom of the crushing box 1. Two crushing rollers 14 are rotatably installed inside the crushing box 1. A driving mechanism acting on the crushing rollers 14 is provided on the outer wall of the crushing box 1. A guide plate 3 is fixedly installed at the upper end of the crushing box 1. A U-shaped frame 6 is provided above the guide plate 3. The bottom two sides of the U-shaped frame 6 are fixedly connected to the support frame 2 through fixed plates 7. An intercepting grid 8 is provided inside the U-shaped frame 6. One end of the intercepting grid 8 is rotatably connected to the U-shaped frame 6 through a rotating shaft 9. A vibration mechanism acting on the swing end of the intercepting grid 8 is provided on the fixed plate 7. There are two vibration mechanisms, which are symmetrically distributed on both sides of the intercepting grid 8. The vibration mechanism consists of a fixed rod 10, a cam 15, a second motor 16, and a second support plate 17.

[0021] The fixing rod 10 is fixedly connected to the side wall of the intercepting grille 8. The side wall of the U-shaped frame 6 is provided with an arc-shaped groove 18 that slides and fits with the fixing rod 10. The bottom of the fixing rod 10 is provided with a cam 15, which is rotatably connected to the side wall of the fixing plate 7. The end of the cam 15 away from the fixing plate 7 is provided with a second motor 16. The bottom of the second motor 16 is fixedly connected to the fixing plate 7 through a second support plate 17. The output shaft of the second motor 16 is fixedly connected to the cam 15.

[0022] In use, starting motor 16 drives cam 15 to rotate. When the protruding end of cam 15 contacts the fixed rod 10, it lifts the intercepting grille 8 upwards. When the protruding end of cam 15 moves away from the fixed rod 10, the intercepting grille 8 swings downwards under the influence of gravity. As cam 15 continues to rotate, the intercepting grille 8 vibrates continuously. It should be noted that the maximum upward lift of the intercepting grille 8 is when it is in a horizontal state. This setting ensures that the ore on the intercepting grille 8 will not roll out from the opening of the U-shaped frame 6.

[0023] The upper end of the arc-shaped groove 18 is open.

[0024] With this setup, when too many large ore stones accumulate on the intercepting grid 8, workers can manually lift it by holding the fixing rod 10, thereby discharging the large ore stones from the opening of the U-shaped frame 6.

[0025] The drive mechanism consists of a No. 1 motor 4, a No. 1 support plate 5, a drive gear 12, and a driven gear 13. The shaft ends of the two crushing rollers 14 extend to the outer wall of the crushing box 1 and are respectively fixedly connected to the drive gear 12 and the driven gear 13. The drive gear 12 and the driven gear 13 are rotatably connected to the outer wall of the crushing box 1. The drive gear 12 and the driven gear 13 mesh with each other. The end of the drive gear 12 away from the crushing box 1 is provided with a No. 1 motor 4. The output shaft of the No. 1 motor 4 is fixedly connected to the drive gear 12. The bottom of the No. 1 motor 4 is fixedly connected to the support frame 2 through the No. 1 support plate 5.

[0026] When in use, starting motor 4 drives the drive gear 12 to rotate, which in turn drives the driven gear 13 to rotate, thereby controlling the two crushing rollers 14 to rotate and crush the ore.

[0027] The diameter of the driving gear 12 is smaller than that of the driven gear 13, which allows the two crushing rollers 14 to rotate at different speeds.

[0028] Among them, the driving gear 12 and the driven gear 13 are provided with a sealing box 11, which is fixedly connected to the outer wall of the crushing box 1.

[0029] The sealed box 11 can protect the driving gear 12 and the driven gear 13.

[0030] This utility model provides a crushing device for raw ore processing, the specific working principle of which is as follows:

[0031] In use, starting motor 16 drives cam 15 to rotate. When the protruding end of cam 15 contacts the fixed rod 10, it will lift the intercepting grid 8 upward. When the protruding end of cam 15 moves away from the fixed rod 10, the intercepting grid 8 will swing downward under the action of gravity. As cam 15 continues to rotate, the intercepting grid 8 will vibrate continuously, thereby screening the ore put into the crushing box 1 and preventing excessively large ore from entering the crushing box 1 and affecting the crushing efficiency. When too many large ore accumulates on the intercepting grid 8, the operator can hold the fixed rod 10 and manually lift it to discharge the large ore on the intercepting grid 8 from the opening of the U-shaped frame 6.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
