Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, in particular to an automatic telescopic conversion device for belt conveyors. Background Art

[0002] Belt conveyor is a friction-driven machine that transports materials in a continuous manner. It is mainly composed of a frame, conveyor belt, rollers, drums, tensioning devices, transmission devices, etc. It can form a material conveying process from the initial feeding point to the final unloading point on a certain conveyor line.

[0003] The automatic telescopic device of the belt conveyor can move the head receiving hopper without changing the coal drop pipe to realize automatic switching of material transfer. At present, the material switching of the belt conveyor is mainly carried out by using the three-way baffle in the coal drop pipe. The material switching can only be realized after the material falls. At the same time, the three-way baffle and its drive device require regular inspection and maintenance, and the failure rate is high. The automatic conversion of materials is not realized. At the same time, when the equipment is automatically telescopically adjusted, the various moving parts cannot obtain stable limit protection operation, and the overall stability of the conveyor belt cannot be guaranteed, and it cannot meet daily use needs. Therefore, it is urgent to design an automatic telescopic conversion device for a belt conveyor to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide an automatic telescopic conversion device for a belt conveyor to solve the problem that the existing automatic telescopic device of the belt conveyor proposed in the above background technology can move the head receiving hopper without changing the coal dropping pipe to realize automatic switching of material transfer. At present, the material switching of the belt conveyor is mainly carried out by using the three-way baffle in the coal dropping pipe. The material switching can only be realized after the material falls. At the same time, the three-way baffle and its driving device need regular inspection and maintenance, and the failure rate is relatively high. The automatic conversion of materials is not realized. At the same time, when the equipment is automatically telescopically adjusted, the various moving parts cannot obtain stable limit protection operation, the overall stability of the conveyor belt cannot be guaranteed, and the daily use needs cannot be met.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic telescopic conversion device for a belt conveyor, comprising a head receiving hopper, a conveyor belt is arranged inside the head receiving hopper, a driven roller is arranged at one end of the conveyor belt, a first tightening roller is arranged at one side of the bottom of the conveyor belt, and a second tightening roller is arranged at the other side of the bottom of the conveyor belt;

[0006] An adjusting tray is movably connected to one side of the head receiving hopper, a first limiting frame is arranged at one end of the bottom of the adjusting tray, and a second limiting frame is arranged at the other end of the bottom wall of the adjusting tray.

[0007] Preferably, connecting frames are fixedly connected to both sides of one end of the adjustment tray, and a limiting sliding roller is provided at one end of the connecting frame.

[0008] Preferably, a limiting slider is provided at one end of the bottom of the adjustment tray.

[0009] Preferably, an overhead bar is fixedly connected to the surface of the adjustment tray, and a laminating roller is provided on the surface of the overhead bar.

[0010] Preferably, a driving rack is provided at the bottom of the adjusting tray, and a driving gear is provided at the bottom of the driving rack.

[0011] Preferably, a driving roller is provided inside the head receiving hopper, and a lower hopper is fixedly connected to the bottom end of the head receiving hopper.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The automatic telescopic transformation device of the belt conveyor can make the equipment perform more efficient automatic telescopic transformation operation through the head receiving hopper, conveyor belt, adjustment tray, overhead bar, bonding roller, drive rack, drive gear, drive roller and lower hopper. In actual use, the staff can place the material to be conveyed on the conveyor belt, and then quickly convey the material to the inside of the head receiving hopper along the movement of the conveyor belt. At the same time, during daily material conveying, the drive gear at the bottom of the adjustment tray can be started to engage and drive the drive rack of the adjustment tray, so that the adjustment tray as a whole drives the head receiving hopper as a whole to perform forward and backward telescopic adjustment operation, and the head receiving hopper as a whole drives the lower hopper to perform telescopic transformation operation of position, thereby realizing material switching. At the same time, the overhead bar and bonding roller on the surface of the adjustment tray can perform stable limited conveying operation with the conveyor belt during transformation, so as to ensure the stability of the material on the surface of the conveyor belt. The extension and retraction of the conveyor belt are automatically performed through the transformation mechanism, which reflects the practicality of the equipment design.

[0014] The automatic telescopic transformation device of the belt conveyor further improves the overall use effect of the equipment by arranging a head receiving hopper, a conveyor belt, a driven roller, a first tightening roller, a second tightening roller, an adjusting tray, a connecting frame, a limit sliding roller and a limit sliding block. In daily use, when the adjusting tray is being adjusted to extend and retract forward and backward, the bottom of the adjusting tray can be limited and slid inside the first limit frame through the limit sliding block at one end of the bottom, and the limit sliding roller connected to one end of the adjusting tray through the connecting frame can also be stably limited and adjusted inside the second limit frame, thereby ensuring that the conveyor belt passing through the interior of the adjusting tray is quickly extended, stretched, straightened and limited. At the same time, the first tightening roller and the second tightening roller on both sides of the bottom wall of the conveyor belt can also perform daily conveyor belt adjustment and limit, ensuring that the conveyor belt is always in a straight state, reflecting the comprehensiveness of the equipment design.
