A bucket elevator

Abstract

The invention relates to the technical field of elevators, and discloses a bucket elevator, which includes a casing, a sprocket is movably connected to the interior of the casing through a rotating shaft, a chain is movably connected to the sprocket, and a chain is fixed on the chain. A fixed block is installed, and an intermediate rod is fixedly installed on the fixed block, a hopper is movably connected to the intermediate rod, and a limit guide rail is fixedly installed on the upper part of the inner wall of the casing. The sprockets are changed to four pairs of sprockets and two pairs of upper and lower pairs. Between the sprockets, a hopper is movably connected to the intermediate rod fixed on the fixed block fixed on it, so that the hopper can always be kept from being upside down. , and it is in the positive position during the process of lifting and unloading, so that it can completely guarantee that there will be no phenomenon of returning material due to the need for the hopper to be inverted during unloading, and improve the conveying rate of materials.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a bucket elevator. Background technique [0002] The existing bucket elevator is mainly a lifting device for conveying materials from a low place to a high place. It is mainly composed of two pairs of sprockets, chains and hoppers. Its working principle is mainly when the hopper passes through the bottom of the casing and stores The material is excavated in it, and then the chain is driven to rotate with the rotation of the sprocket, so that the hopper rises. When the hopper reaches the other side of the top, the hopper will slowly turn the opening downward to discharge, thus completing However, the existing bucket elevators always have the following problems: [0003] The hoppers of the existing bucket elevators are all fixedly installed on the chain, and it will turn along with the turning of the chain, and in this way, the hopper will be in high resistance during the whole ...

AI Technical Summary

Problems solved by technology

[0003] The hoppers of the existing bucket elevators are all fixedly installed on the chain, and it will turn along with the turning of the chain, and this way makes the hopper be in high resistance during the whole process of digging at the bottom of the casing The digging process keeps the load of the motor at a high level continuously, increasing the consumption of the motor, and it is also not conducive to the normal use of the chain, which makes the chain's bearing capacity too large and easily leads to chain breakage. When unloading at the top of the hopper, because the hopper itself does not have the function of rotation, when the mouth of the hopper starts to tilt downward, the unloading has already started, but at this time the hopper does not reach the discharge port, even if the existing through the tongue Plates are used to reduce material return, but there will still be more material return, resulting in a reduction in material delivery rate
