Description

Technical Field

[0001] The utility model relates to the technical field of conveyors, in particular to a belt conveyor. Background Art

[0002] Belt conveyor is a continuous transport machine that uses belt as traction and load-bearing component. The belt is wound around the driving roller and various redirecting rollers, and is given appropriate tension by the tensioning device. When working, the conveyor belt is driven by the driving device, through the friction and tension between the roller and the conveyor belt, so that the conveyor belt runs. The material is continuously sent to the conveyor belt and moves with the conveyor belt, thereby realizing the transportation of the material.

[0003] In the prior art, a general belt conveyor places bulk materials on the top surface of the belt, and then the belt rotates to transfer the bulk materials. However, the efficiency of the belt conveyor is not high. If the speed of the belt is increased, the bulk materials may be carried away from the belt by the airflow and scattered. Increasing the width of the belt will affect the overall size of the belt conveyor, causing the belt conveyor to occupy the area of ​​other areas in the factory building, or making the transfer or installation of the belt conveyor more difficult. In addition, when two different materials need to be transported, in order to prevent the materials from being mixed together, two belt conveyors are generally set up, which is extremely inconvenient when the space is limited. Therefore, it is necessary to optimize the effective belt conveyor. Utility Model Content

DETAILED DESCRIPTION

[0015] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0016] like Figure 1As shown, an embodiment of the utility model proposes a belt conveyor, including a belt, a plurality of redirecting rollers 7 for redirecting the belt, and a motor for driving the redirecting roller 7 to rotate. The belt includes a first transmission section 1 and a second transmission section 2 which are arranged horizontally and have corresponding intervals above and below. A first connecting section 6 is arranged between the starting end of the first transmission section 1 and the ending end of the second transmission section 2. The first connecting section 6 is located on the side and below the first transmission section 1 and the second transmission section 2. A second connecting section 3 is arranged between the ending end of the first transmission section 1 and the starting end of the second transmission section 2. The second connecting section 3 is located between the first transmission section 1 and the second transmission section 2. The belt turns after passing through the redirecting roller 7. The motor is used to drive the redirecting roller 7 to drive the belt to rotate. A support frame is also included, and the support frame is rotatably connected to the roller. The running track of the belt is generally in a concave shape, and the opening of the concave track faces the horizontal side.

[0017] Preferably, a main hopper 10 is fixedly provided on the side of the starting end of the second transmission section 2, and the discharge port of the main hopper 10 extends horizontally to the top of the second transmission section 2, and the discharge port of the main hopper 10 is located below the second connecting section 3. When transporting materials, the staff uses the transfer setting to pour the bulk material above the main hopper 10, so that the bulk material is continuously supplied from the main hopper 10 to the second transmission section 2. The influence of the second connecting section 3 above the second transmission section 2 on the feeding is avoided. In this embodiment, a sub-hopper is fixedly provided on the first transmission section 1. This allows both the first transmission section 1 and the second transmission section 2 to use the hopper for feeding.

[0018] Preferably, the first connecting section 6 is curved, and the upward end of the first connecting section 6 is connected to the starting end of the first transmission section 1, and the downward end of the first connecting section 6 is connected to the tail end of the second transmission section 2. There is a gap between the first connecting section 6 and the second transmission section 2. In this embodiment, a redirecting roller 7 is provided at the position where the second connecting section 3 is bent. The second connecting section 3 is bent so that it will not contact the second transmission section 2 during operation.

[0019] Preferably, baffles are provided on both sides of the belt to prevent materials from scattering from both sides of the belt.

[0020] Preferably, the belt further comprises a telescopic rod 8 and a spring 9. The telescopic rod 8 is horizontally arranged and perpendicular to the axis of the redirecting roller 7 at the corner of the second connecting section 3. One end of the telescopic rod 8 is fixedly arranged, and the other end of the telescopic rod 8 is rotationally connected to the rotating shaft of the redirecting roller 7 at the bend of the first connecting section 6. The spring 9 is coaxial with the telescopic rod 8, and the two ends of the spring 9 are respectively connected to the movable section and the fixed section of the telescopic rod 8. When the belt is used for a long time, it will be stretched. In order to keep the belt and the redirecting roller 7 tight and maintain sufficient friction, the telescopic rod 8 and the spring 9 move the connected redirecting roller 7, thereby tightening the belt.

[0021] Preferably, the end of the second transmission section 2 is located on the side of the end of the first transmission section 1 that is biased toward the starting end. A partition plate 11 is provided between the tail ends of the first transmission section 1 and the second transmission section 2. After the material is discharged from the first transmission section 1 and the second transmission section 2, the partition plate 11 allows the material to enter different equipment from two heights, upper and lower.

[0022] Preferably, the bottom surfaces of the second connecting section 3 and the first connecting section 6 are abutted with a fixedly arranged inclined scraper 12, the bottom of the scraper 12 is fixedly connected with a storage box 13 with an opening at the top, the bottom of the storage box 13 is inclined, and a discharge port is arranged on a side of the storage box 13 facing downward. In this embodiment, when the scraper 12 contacts the belt, the material remaining on the belt is shoveled away, and the residue falls into the storage box 13 and is discharged.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
