Description

Technical Field

[0001] The utility model belongs to the technical field of mining and exploitation, and particularly relates to a limestone transfer conveyor belt. Background Art

[0002] The processing of limestone requires a series of processes and equipment. When limestone is transported between equipment, it is generally transported by conveyor belts. In the existing limestone processing, some processes have certain requirements for the size of limestone, and smaller limestone needs to be screened and removed. However, during the transportation of limestone, there will be a height difference, and the existing conveyor belt has no shock-absorbing effect. Therefore, when the limestone falls on the conveyor belt, it will generate a large impact force between the conveyor belt and the limestone. This impact force may not only cause the limestone to break and produce fine limestone, which will affect the limestone processing. It may even cause vibration damage to the conveyor belt, resulting in economic losses.

[0003] Therefore, a limestone transfer conveyor belt is needed. Utility Model Content

[0004] The purpose of the utility model is to provide a limestone transfer conveyor belt, so as to overcome the defect that the existing limestone conveyor belt has no shock absorption effect, so when the limestone falls onto the conveyor belt, it is easy to break, which affects the subsequent processing. The specific technical scheme is as follows:

[0005] A limestone transfer conveyor belt comprises a fixed frame, a support rod, a mounting frame, a first roller, a second roller, an auxiliary roller, a belt body and a buffer energy absorption unit.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example, reference Figures 1 to 5 .

[0025] A limestone transport conveyor belt comprises a fixed frame 1, a support rod 2, a mounting frame 3, a first roller 4, a second roller 5, an auxiliary roller 6, a belt body 7 and a buffering energy absorbing unit, wherein one end of a plurality of support rods 2 is vertically arrayed on the fixed frame 1, first rollers 4 are mounted at both ends of the fixed frame 1, the mounting frame 3 is arrayed and mounted on the side of the fixed frame 1 away from the support rod 2, the mounting frame 3 is divided into an inclined portion 302 and a horizontal portion 301, the inclined portion 302 is symmetrically located at both ends of the horizontal portion 301, two buffering energy absorbing units form a group, each group of buffering energy absorbing units is mounted at both ends of the horizontal portion 301 and the inclined portion 302, the two ends of the second roller 5 are respectively connected to the buffering energy absorbing unit, the auxiliary roller 6 is arrayed and mounted on the side of the fixed frame 1 away from the mounting frame 3, and the belt body 7 is sleeved on the first roller 4, the second roller 5 and the auxiliary roller 6. Since ore is easy to roll, in order to prevent the ore from rolling off the conveyor belt during transportation, the existing ore conveyor generally adopts a conveyor belt with inclined sides. Therefore, a group of buffer energy absorbing units are installed on both the horizontal portion 301 and the inclined portion 302. The buffer energy absorbing units can also be installed in the blanking area of ​​the conveyor belt according to actual conditions to reduce costs.

[0026] The buffering energy absorption unit includes a first guide cylinder 10, a first guide rod 8, a first spring 12 and a damping rod 14. One end of the first guide cylinder 10 is vertically mounted on the mounting frame 3. The first guide rod 8 is slidably mounted in the first guide cylinder 10. The first spring 12 is mounted in the first guide cylinder 10, and the two ends of the first spring 12 are elastically supported by the first guide rod 8 and the inner wall of the first guide cylinder 10 respectively. The damping rod 14 is mounted in the first guide cylinder 10, and the two ends of the damping rod 14 are respectively connected to the first guide rod 8 and the inner wall of the first guide cylinder 10. The end of the first guide rod 8 away from the first spring 12 is connected to one end of the second roller 5. When the limestone falls from a height, the first spring 12 and the damping rod 14 will absorb part of the impact force generated by the limestone, thereby reducing the force between the limestone and the conveyor belt, reducing the occurrence of limestone fragmentation, and reducing the impact on subsequent processing. At the same time, the buffering energy absorption unit not only extends the service life of the conveyor belt, but also reduces the generation of dust during the transportation of limestone and reduces the pollution of the environment in the factory.

[0027] The two ends of the second roller 5 are rotatably connected to the first guide rod 8 through hinges, and the rotation axis of the second roller 5 is a telescopic rod. The distribution of limestone falling on the conveyor belt is not necessarily uniform, so the impact force on one side of the conveyor belt is greater per unit time. At this time, the second roller 5 rotates obliquely, and the rotation axis of the second roller 5 will extend to meet the distance between the two ends of the first guide rods 8, thereby reducing the lateral component of force on the first conductor rod, thereby avoiding the first conductor rod and the first guide cylinder 10 from getting stuck, and extending the service life of the first guide rod 8 and the first guide cylinder 10.

[0028] The cleaning unit includes a collection box 15, a cross bar 16, a brush 17, a second guide rod 9, a second guide cylinder 11 and a second spring 13. The collection box 15 is placed directly below the belt body 7. The cross bar 16 is horizontally mounted on the support rod 2. The second guide cylinder 11 is vertically arrayed on the cross bar 16. The second guide rod 9 is slidably mounted in the second guide cylinder 11. The second spring 13 is mounted in the second guide cylinder 11, and the two ends of the second spring 13 are elastically supported against the second wire rod and the inner wall of the guide cylinder respectively. The end of the second guide rod 9 away from the cross bar 16 is jointly mounted with the brush 17. The second spring 13 will continuously push the brush 17 to move in the direction close to the belt body 7, so that there is a certain pressure between the brush 17 and the belt body 7 to ensure the cleaning effect of the brush 17. The brush 17 cleans the idle part of the belt body 7 to prevent limestone from remaining on the belt body 7. When the part of the belt body 7 that occupies the limestone rotates to the drop area, the limestone that falls onto the belt body 7 collides with the limestone on the belt body 7, which may cause both to break. Therefore, the cleaning unit can further reduce the breakage of limestone during transportation.

[0029] The brush 17 is in an arc shape, and the diameter of the brush 17 is greater than the width of the cross bar 16. The arc-shaped brush 17 can make the cleaned fine limestone fall into the collection box 15 along the arc surface, avoiding the situation that the fine limestone stays on the brush 17 after being cleaned by the brush 17, and scratches the belt body 7 when the brush 17 cleans the belt body 7 later. When the arc radius of the brush 17 is greater than the width of the cross bar 16, it can prevent the fallen gravel from falling and accumulating on the cross bar 16. The width of the collection box 15 is greater than the width of the belt body 7, which prevents the gravel from falling outside the collection box 15, resulting in the need for manual cleaning later, increasing labor costs. The brush 17 uses a hard brush 17 to obtain a better cleaning effect.
