Description

Technical Field

[0001] The utility model relates to the technical field of coal transportation, in particular to a coal conveyor capable of preventing material jamming and clogging. Background Art

[0002] A coal conveyor is a device for conveying coal. When the device is in use, material compression, blockage and tearing mostly occur at the lower part of the chute. Since the distance between the front edge of the chute and the belt surface is limited, and the supporting rollers under the belt are distributed at intervals, the natural bearing capacity is uneven. When the length of the transported material exceeds this distance, under special circumstances, large pieces of material are easily stuck between the front edge of the chute and the belt, which can easily cause material compression and blockage on the belt of the coal conveyor. In order to avoid damage to the belt of the coal conveyor, a coal conveyor that prevents material compression and blockage is provided.

[0003] In the existing coal conveyor, large pieces of material get stuck between the front edge of the chute and the belt. In addition, although some gangue has been crushed, the edges and corners are still very sharp, which causes the belt to be squeezed and scratched and torn, resulting in damage to the coal conveyor and inability to use. Secondly, when the feed amount at the loading point suddenly increases, it will also cause the belt loading on the coal conveyor to be blocked. Under the long-term friction operation of the belt, it will also cause the belt to tear, thus affecting the use of the coal conveyor. In response to the above problems, an innovative design is carried out on the basis of the original coal conveyor. Utility Model Content

[0004] The purpose of the utility model is to provide a coal conveyor which can prevent material jamming and clogging, so as to solve the problem proposed in the above background technology that large pieces of material are jammed between the front edge of the chute and the belt in the existing coal conveyor, and some gangue, although crushed, still have sharp edges and corners, so that the belt is strongly squeezed and scratched and torn, resulting in damage to the coal conveyor and inability to use. Secondly, when the feed amount at the loading point suddenly increases, it will also cause the belt loading on the coal conveyor to be blocked. Under the long-term friction operation of the belt, it will also cause the belt to tear, thus affecting the use of the coal conveyor.

[0005] To achieve the above object, the utility model provides the following technical solution: a coal conveyor for preventing material jamming and clogging, comprising a belt and a chute, wherein the chute is located on the upper side of the belt, a motor is installed on the side of the chute, a driving rod is connected to the output end of the motor, and a baffle is installed on the driving rod;

[0006] A motor is installed on the side of the chute, a crushing knife is arranged on the output end of the motor, limit rails are installed on both sides of the chute, a control panel is arranged on the side of the limit rails, a limit hole is provided at the lower end of the limit rails, and a slider is arranged in the limit rails;

[0007] Screw rods are arranged on both sides of the sliding block, and nuts are connected to the screw rods. A connecting rod and a guide rod are connected to the sliding block, and a buffer platform is installed on the connecting rod and the guide rod.

[0008] Preferably, the driving rod and the baffle are designed as one piece, and the driving rod and the output end of the motor are fixedly connected.

[0009] Preferably, the slider and the limiting rail are connected in a nested sliding manner, and the slider and the screw are designed as an integral whole.

[0014] The utility model of the coal conveyor for preventing material jamming and clogging has the following beneficial effects:

[0015] 1. Through the connection between the driving rod and the baffle, the baffle can be driven to rotate when the motor is running. The rotating baffle rotates to adjust the diameter of the material discharge.
