Description

Technical Field

[0001] The utility model relates to the technical field of belt transmission, in particular to a material blocking protection device for a belt conveyor. Background Art

[0002] The belt conveyor uses a motor to drive the wheel to rotate, so that the belt moves periodically, thereby driving the material on the top of the belt to be transported. The belt conveyor is widely used in various fields of industrial production.

[0003] When belt conveyors are used in mines, they usually work in conjunction with chutes. After transporting the minerals, the belt conveyors discharge them to an area through bucket-shaped chutes. However, during the use of bucket-shaped chutes, the chutes are often blocked, which makes it impossible for the materials in the chute to be discharged smoothly. The belt conveyor is always running. If it is not discovered in time, the materials may overflow after filling the chute and come into contact with the belt on the conveyor, thereby wearing the belt during the operation of the belt, and finally reducing the service life of the belt conveyor. At the same time, once the chute is blocked, it is difficult to clean, and the staff need to use tools such as wooden sticks to pound and dredge it, which is time-consuming and labor-intensive, and the dredging efficiency is relatively low.

[0004] Therefore, it is necessary to provide a new belt conveyor material blocking protection device to solve the above technical problems. Utility Model Content

[0030] Threaded cylinders 19 are fixedly installed on the inner walls of both sides of the external box 1. The two threaded cylinders 19 respectively penetrate the inner walls of both sides of the external box 1 and extend to the outside of the external box 1. Contact plates 21 are slidably installed on the inner walls of both sides of the external box 1. Two sliding rods are fixedly installed on one side of the two contact plates 21.

The convex shaft is connected to the inner wall of the bearing cylinder 1901 through a bearing.

[0031] The working principle of the belt conveyor material blocking protection device provided by the utility model is as follows:

[0032] In the initial state, the half circles of the two eccentric wheels 15 away from the center are both facing inward (close to the side of the guide bucket 302), and the two contact plates 21 push the two sliding frames 9 to the innermost side respectively, so that one side of the two sliding frames 9 contacts the outer walls of the two sides of the guide bucket 302 respectively, thereby maintaining the stability of the guide bucket 302 and the guide tube 301 and preventing them from shaking.

[0033] During the material transportation process, the external box 1 is fixed to the end position of the belt conveyor through the mounting frame 2. The material on the belt conveyor is gathered by the top bucket 4 and then discharged to a suitable position through the conduit 301 and the guide bucket 302.

[0034] When the guide tube 301 and the guide bucket 302 are blocked by materials, the staff can rotate the two threaded rods 20 respectively. The two threaded rods 20 will move away from each other under the screw transmission of the two threaded cylinders 19, so that the two contact plates 21 will move away from each other and separate from the two sliding frames 9. At this time, the limiting effect of the guide bucket 302 and the guide tube 301 will be contacted. The guide tube 301 and the guide bucket 302 will maintain a certain shaking amplitude under the effect of the fixed plate 503. Then the motor 11 can be started. When the output shaft of the motor 11 is started, the active rod 801 will be driven to rotate. Under the transmission effect of the four synchronous pulleys 2 18 and the two transmission belts 2, the two driven rods 16 will be driven to rotate and connect respectively. The two driven rods 16 rotate and connect with the four synchronous pulleys 1 17 and the two transmission belts 1 Under the transmission effect, the two rotating shafts 14 will be driven to rotate respectively, thereby driving the two eccentric wheels 15 to rotate. During the rotation of the two eccentric wheels 15, when the eccentric wheels 15 rotate to the outside (away from the guide bucket 302) half a circle away from the center of the circle, they will conflict with the two sliding frames 9 to move away from each other, and at the same time stretch the return spring 10 to put it in a stretched energy storage state. When the two eccentric wheels 15 rotate to the inside (close to the guide bucket 302) half a circle away from the center of the circle, the sliding frames 9 will quickly approach each other under the pulling effect of the return spring 10, thereby hitting the outer walls of the two sides of the guide bucket 302. Under the continuous operation of the motor 11, the two sliding frames 9 will quickly hit the guide bucket 302, thereby achieving the effect of vibrating the guide bucket 302, thereby achieving the effect of dredging materials and avoiding the occurrence of blockage.

[0035] Compared with the related art, the belt conveyor material blocking protection device provided by the utility model has the following beneficial effects:

[0036] The utility model provides a belt conveyor material blockage protection device. During the process of using the belt conveyor to transport materials, once material blockage occurs in the guide bucket 302, after starting the motor 11, the two sliding frames 9 are driven to move rapidly, thereby achieving the effect of rapid impact on the outer wall of the guide bucket 302, so that the guide bucket 302 maintains a frequent vibration effect, thereby vibrating and dredging the material, thereby avoiding the situation of material blockage.
