Description

Technical Field

[0001] The utility model relates to the technical field of hoist head equipment, in particular to a novel hoist head. Background Art

[0002] An elevator is a mechanical device that transports materials by changing potential energy. Bucket elevators are one type of equipment. Bucket elevators use a series of hoppers fixed to a traction chain or belt to transport bulk materials upward in a vertical or nearly vertical direction. The hoppers scoop up the materials from the storage below, lift them to the top along the conveyor belt or chain, pass the top wheel, and then turn downward to pour the materials into the receiving trough to achieve the lifting function.

[0003] When the elevator is in use, it usually needs to be driven by an electric motor through the elevator head to provide it with driving kinetic energy. However, most of the existing elevators currently use chain drive or belt drive, which has high maintenance costs and short service life, and is inconvenient to use. Utility Model Content

[0007] As a further solution of the present invention: the bearing seat assembly, the bearing fixing flange, the sliding plate and the sliding plate fixing piece are each provided with two groups symmetrically arranged at both ends of the tension adjustment mechanism.

[0008] As a further solution of the present invention: the cover plate, the pressure cover, the maintenance plug plate and the shell are each provided with two groups symmetrically arranged at both ends of the upper cover.

[0009] As a further solution of the present invention: a strip-shaped through-slot structure is provided at the bent portion below the motor fixing plate, and the strip-shaped through-slot at the bent portion of the motor fixing plate passes through the bottom of the motor fixing plate.

[0010] As a further solution of the present invention: the hoppers are provided in multiple groups and are evenly and fixedly arranged on the outside of the belt, and the position of the discharge adjustment plate is adapted to the hoppers.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The hoist head of the utility model has the advantages of compact structure, simplicity, easy maintenance and high efficiency, especially the improvement of the belt tension adjustment mechanism. By rotating the adjustment screw, the top plate will push the spring upward, the spring will be compressed and push the adjustment component upward, the belt will be tightened, and the adjustment action will be completed. After the belt has been working for a long time and naturally stretched, the compressed spring will pop out and tighten within a certain range. In this way, the belt tension can be adjusted flexibly and conveniently. The transmission part adopts a direct connection method, which improves the transmission efficiency and reduces maintenance costs compared with chain drive or belt drive. The chain of the chain drive needs to be lubricated and replaced regularly, and the belt is easy to slip and lose rotation, and has a short service life. The inspection port adopts a pull-out plug-in structure, which is more convenient and quicker than the bolt-fixed type. BRIEF DESCRIPTION OF THE DRAWINGS
