Spiral unloading device

Abstract

A helical unloading apparatus is used in a bad condition to have a reasonable structure, good strength, large moment, no failure in working, long service life, to be easy for maintenance and suitable for various vehicles, and low operating cost. It consists of a support beam of T-shape box, a motor, a transmission, an output shaft, and a pair of spiral bodies. The motor is installed on the said beam at it central position. The transmission is installed under the beam and connected with the motor. The output shaft is extended from both sides of the transmission. The pair of spiral bodies is symmetrically installed on the both sides of the output shaft. The both ends of the T-shape beam are connected with a lift trolley mechanism.

Description

Technical field: [0001] The invention belongs to a vehicle unloading device for unloading bulk materials loaded by trains and automobiles from the compartments, and in particular relates to a structural improvement of a screw unloading device. Background technique: [0002] At present, one type of screw unloading device for unloading bulk materials loaded by trains and automobiles from the compartment is a support structure at both ends of the screw and an open chain drive. The problem is that the two ends of the screw are supported by the arm Covering, the actual working area in the cargo box is short, and the goods at both ends of the spiral cannot be completely unloaded, and cleaning needs to be done after unloading; the open chain drive has no chain tensioning mechanism, which is not easy to adjust and tension the chain. The transmission mechanism wears quickly and the bearings are easily damaged. The other type is an improvement on the old-fashioned equipment, which ad...

Problems solved by technology

[0002] At present, one type of screw unloading device for unloading bulk materials loaded by trains and automobiles from the compartment is a support structure at both ends of the screw and an open chain drive. The problem is that the two ends of the screw are supported by the arm Covering, the actual working area in the cargo box is short, and the cargo at both ends of the spiral cannot be completely unloaded, and cleaning needs to be done after unloading; open chain drive, and there is no chain tensioning mechanism, it is not easy to adjust the tension chain

This type of unloading device solves the disadvantages of the above-mentioned two-end support type. Because the supporting beam adopts a V-shaped structure, there is a problem of insufficient rigidity; the transmission box has a thicker box because its lower structure takes up a lot of space. During unloading operations, The box body is subject to great resistance from materials (especially frozen and hardened materials), which increases the drop load, and at the same time, the materials under the box body cannot be unloaded cleanly.

The unreasonable structure of the above two types leads to frequent equipment failures, high equipment maintenance costs, high operating costs, and short service life. It is not suitable for truck unloading conditions with large differences in vehicle models.
