People focus on the improvement and breakthrough of grinding technology, and pay attention to the research on using extrusion grinding technology to replace impact grinding technology, so as to improve the utilization rate of grinding function and reduce the comprehensive power consumption of cement production. Therefore, cement grinding technology innovation, cement grinding station needs to load materials when making cement. Usually, the staff pushes the materials through a cart. The cart is pushed at a high height, the work intensity is high, and the work efficiency is low, so the patent number is: CN20202231560 A technical solution is disclosed in 3.4, but there are still some problems when using this technical solution. This technical solution requires manual labor to continuously put materials on the conveyor belt before the materials can be loaded. Although this method of putting materials can be used for loading materials, the manual feeding is not accurate, resulting in different amounts of material being loaded each time, which may cause too much or too little raw materials in the grinding process, thereby affecting the working efficiency of the equipment. In addition, continuous manual feeding will cause fatigue among workers at work, thereby affecting the working efficiency of the equipment.

[0003] Based on this, the utility model designs a raw material automatic lifting and feeding device for a cement grinding machine to solve the above problems. Utility Model Content

[0008] Preferably, the material receiving mechanism includes a mounting seat, a second rotating column, a material receiving box, a torsion spring, a second gear and a pad. The mounting seat is installed on the conveyor belt, and the mounting seat is rotatably connected to the second rotating column. The material receiving box is installed on the second rotating column, and the material receiving box is sleeved with a torsion spring. The second gear is installed on the second rotating column, and the second gear and the gear ring are movably connected. The bottom surface of the material receiving box is installed with a pad.

[0012] The utility model places the material to be put in the hopper, at which time one of the material receiving mechanisms is located at the lower side of the quantitative box, and then controls the driving motor to work. Since the two half gears are installed in a staggered manner, when one of the half gears is meshed with the third gear, the other half gear is disengaged from the first gear. At this time, the driving motor controls the half gear to drive the third gear to rotate, and then the quantitative shaft on the third rotating column starts to rotate. When the quantitative shaft rotates, the quantitative shaft accurately puts the material into the material receiving box. When enough material is put into the material receiving box, the half gear is disengaged from the third gear, and at the same time, the other half gear is meshed with the first gear, and then the conveyor belt is moved, thereby moving the material receiving mechanism. When one material receiving mechanism is in operation, the third gear is disengaged, and the other half gear is meshed with the first gear. When moving out from the lower side of the quantitative mechanism, another material receiving mechanism enters the lower side of the quantitative mechanism again. At this time, the first gear and the half gear are disengaged, and the other half gear is meshed with the third gear again. This is repeated, which can effectively realize the automatic loading of the equipment and make the equipment more accurate in feeding materials, avoiding uneven feeding of materials when feeding. With the transportation of the conveyor belt, when the material receiving mechanism moves to the gear ring, the second gear and the gear ring are meshed, and the second gear rotates on the gear ring, and then the material receiving box is turned over, thereby effectively speeding up the feeding efficiency of the equipment, making the equipment faster in feeding, further improving the feeding accuracy and efficiency of the equipment, and reducing the use of manpower.

The conveyor belt 6 is transmission-connected between the two first rotating columns 5.

The mounting seat 9 is installed on the conveyor belt 6, and the second rotating column 10 is rotatably connected to the mounting seat 9. The material receiving box 11 is installed on the second rotating column 10, and the torsion spring 12 is sleeved on the material receiving box 11. The second rotating column 10 is installed with a second gear 13, and the second gear 13 and the gear ring 15 are movably connected. The bottom surface of the material receiving box 11 is installed with a pad 14; it is convenient to collect the material discharged from the quantitative mechanism 16, thereby completing the transportation and delivery of the material.

[0024] Among them, the quantitative mechanism 16 includes a quantitative box 17, a third rotating column 18, a quantitative shaft 19, a hopper 20 and a third gear 21. The quantitative box 17 is installed on the base 1, and the third rotating column 18 is rotatably connected in the quantitative box 17. The quantitative shaft 19 is installed on the third rotating column 18, the third gear 21 is installed on the third rotating column 18, and the hopper 20 is installed on the quantitative box 17; it is convenient to control the amount of material being fed, and avoid the situation of too much or too little material during feeding, thereby affecting the abrasive efficiency of the equipment.

[0026] Working principle:

[0027] During operation, the material to be put in is placed in the hopper 20. At this time, one of the material receiving mechanisms 8 is located at the lower side of the quantitative box 17. Then the drive motor 23 is controlled to work.

When the quantitative shaft 19 rotates, the quantitative shaft 19 accurately puts the material into the material receiving box 11. When enough material is put into the material receiving box 11, the half gear 24 is disengaged from the third gear 21, and at the same time, the other half gear 24 is meshed with the first gear 7, and then the conveyor belt 6 is moved, thereby moving the material receiving mechanism 8. When one receiving mechanism 8 moves out from the lower side of the quantitative mechanism 16, the other receiving mechanism 8 enters the lower side of the quantitative mechanism 16 again. At this time, the first gear 7 and the half gear 24 are disengaged, and the other half gear 24 is meshed with the third gear 21 again. This is repeated, which can effectively realize the automatic feeding of the equipment and make the equipment more accurate in feeding materials, avoiding uneven feeding of materials when feeding. With the transportation of the conveyor belt 6, when the receiving mechanism 8 moves to the gear ring 15, the second gear 13 and the gear ring 15 are meshed, and the second gear 13 rotates on the gear ring 15, and then the receiving box 11 is turned over, thereby effectively speeding up the feeding efficiency of the equipment, making the equipment faster in feeding, further improving the feeding accuracy and efficiency of the equipment, and reducing the use of manpower.
