[0002] Ore is a kind of stone containing some valuable minerals mined from mines, such as iron ore, copper ore, etc. It can be used in engineering fields such as construction industry, railway construction units and cement industry, but the ore cannot be used directly and needs to be processed. The ore processing flow mainly includes screening, grading and crushing. In the process of crushing ore, due to the different hardness of ores of different materials, the amount of material fed each time needs to be adjusted when crushing different ores. However, traditional ore crushing equipment generally puts a large amount of ore directly into the hopper for crushing, which is not convenient for fully crushing different types of ores. In addition, it is difficult for traditional ore crushing equipment to achieve quantitative feeding, resulting in insufficient ore crushing. Utility Model Content

[0016] Example 1: A quantitative feeding ore crushing device, such as Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, it includes a base frame 1, a crusher 2, a rotating shaft 3, a toothless gear 4, a motor 5, a transmission assembly 6, a hollow round shell 7, a lower hopper 8, a multi-slot hollow column 9, a column gear 10, a reducing block 11, a screw rod 12, an arc groove plate 13 and a groove block 14. The crusher 2 is welded on the upper side of the base frame 1, and the upper part of the crusher 2 is rotatably connected to the rotating shaft 3. The toothless gear 4 is connected to the rotating shaft 3 through a flat key. The motor 5 is welded on the base frame 1, and a shaft 3 is provided between the output shaft of the motor 5 and the rotating shaft 3. Transmission assembly 6, which consists of a transmission belt and two transmission discs. The end of the rotating shaft 3 away from the crusher 2 and the output shaft of the motor 5 are connected to the transmission disc through a flat key. A transmission belt is wound between the two transmission discs. The rotation of the transmission assembly 6 will drive the rotating shaft 3 to rotate. The upper part of the crusher 2 is connected to a hollow circular shell 7 by bolts. The upper and lower parts of the hollow circular shell 7 are provided with holes for controlling the direction of ore in and out. The upper part of the chassis 1 is connected to a lower hopper 8 by a latch. The core shell 7 and the lower hopper 8 are connected by bolts, and the lower hopper 8 and the hollow shell 7 are connected, so that the ore falls on the reducer block 11 through the lower hopper 8 and the hollow shell 7. The hollow shell 7 is rotatably connected with a multi-groove hollow column 9, and the multi-groove hollow column 9 is rotatably connected with the upper part of the crusher 2. One end of the multi-groove hollow column 9 is fixedly connected with a column gear 10, and the column gear 10 is meshed with the missing tooth gear 4. The number of gears of the missing tooth gear 4 is one sixth of the column gear 10. The multi-groove hollow column 9 There are six reducing blocks 11 connected in an internal sliding manner, and the six reducing blocks 11 are all located in the hollow circular shell 7. A screw rod 12 is connected to the multi-slot hollow column 9 through a thread. A handle is provided at one end of the screw rod 12. The capacity of the reducing block 11 can be adjusted by turning the handle. The other end of the screw rod 12 is connected to an arc slot disk 13 through a rivet. Six slot holes are evenly opened on the arc slot disk 13. Slot blocks 14 are fixedly connected to the six reducing blocks 11, and the slot blocks 14 are slidably connected to the slot holes on the arc slot disk 13.

[0017] When the utility model is used, the operator first starts the motor 5 and the crusher 2, confirms the amount of ore to be crushed according to the type of ore, and rotates the handle at one end of the screw rod 12 counterclockwise. The rotation of the handle drives the arc slot plate 13 at the other end of the screw rod 12 to rotate, and the six slot holes on the arc slot plate 13 rotate and drive the six slot blocks 14 and the six reducing blocks 11 to slide outward together, so that the capacity of the six reducing blocks 11 is reduced, thereby reducing the ore holding capacity on the reducing blocks 11, effectively controlling the amount of ore fed. Then the operator puts the ore into the hopper 8, and the ore enters the hollow circular shell 7 through the hopper 8 and falls on one of the reducing blocks 11. The motor 5 drives the transmission disc at the bottom to rotate through the output shaft, and the transmission belt rotates to drive the transmission disc at the top to rotate, so that the transmission assembly 6 rotates, thereby driving the rotating shaft 3 to rotate, and the rotating shaft 3 rotates to drive the missing The toothed gear 4 rotates, and the toothless gear 4 rotates to intermittently engage or disengage with the column gear 10, thereby causing the column gear 10 to rotate intermittently. The rotation of the column gear 10 drives the intermittent multi-slot hollow column 9 to rotate, so that the screw rod 12 rotates intermittently together with the multi-slot hollow column 9, thereby fixing the capacity of the reducing block 11 in the adjusted state. The rotation of the multi-slot hollow column 9 drives the six reducing blocks 11 to rotate intermittently together, and the ore in the hopper 8 will continue to fall on another reducing block 11. When the reducing block 11 filled with ore rotates to the outlet at the lower part of the hollow shell 7, the ore on the reducing block 11 falls due to its own gravity and falls into the crusher 2. The crusher 2 will crush the ore. Through the above operation, it is convenient to adjust the feeding amount of the ore, thereby facilitating the crushing of different types of ores. At the same time, quantitative feeding can be carried out to facilitate sufficient crushing of the ore.

[0018] Embodiment 2: Based on embodiment 1, Figure 2-Figure 4 As shown, it also includes a cam plate 15, a bracket 16 and a reset spring 17. The other end of the multi-slot hollow column 9 is connected to the cam plate 15 through a flat key. Six protrusions are evenly arranged on the cam plate 15. The upper part of the base frame 1 is slidably connected to the bracket 16. The lower part of the bracket 16 is provided with a ball. The ball at the lower part of the bracket 16 contacts the cam plate 15. A reset spring 17 is connected between the base frame 1 and the bracket 16.

[0019] The rotation of the multi-slot hollow column 9 drives the cam plate 15 to rotate. The cam plate 15 is provided with six protrusions. The rotation of the cam plate 15 will intermittently contact and disengage with the bracket 16. When the protrusion on the cam plate 15 rotates to contact with the bracket 16, the protrusion on the cam plate 15 will push the bracket 16 to move upward, and the reset spring 17 is stretched. When the cam plate 15 continues to rotate, the protrusion on the cam plate 15 disengages from the bracket 16, and the reset spring 17 resets and drives the bracket 16 to move downward and reset. The ball at the lower end of the bracket 16 will be stuck between two of the protrusions of the cam plate 15, thereby limiting the cam plate 15, and then the cam plate 15 and the multi-slot hollow column 9 will pause after rotating one-sixth of a circle each time, so that the workers can better rotate the screw rod 12 and adjust the capacity of the reducer 11. After the ore crushing is completed, the operator turns off the motor 5 and the crusher 2.
