Spiral material lifter for grain storage and transportation

Abstract

The invention discloses a spiral material lifter for grain storage and transportation. The spiral material lifter comprises a first shell and a second shell, wherein the first shell and the second shell are each internally and rotationally connected with a cylinder, and limiting grooves are formed in the inner side wall of the first shell and the inner side wall of the second shell. Limiting blocks are fixedly connected to the outer side walls of the two ends of each cylinder. The limiting blocks are rotationally connected with the interiors of the limiting grooves. According to the lifter, aninner spiral auger and an outer spiral auger are arranged, by means of a variable-direction transmission device, the inner spiral auger and the outer spiral auger can lift materials, and the materials which adhere to each other and cake due to dampness are extruded and staggered due to the lifting speed difference caused by different rotating speeds, so that the situation that the materials adhere to each other and cake due to dampness and accordingly the lifting speed of the spiral material lifter is influenced is prevented. Besides, by means of magnetic fields changing in the cylinders, aneddy current effect in the inner spiral auger is promoted, then heating is achieved, and the lifted materials in the cylinders are dried and heated.

Description

technical field [0001] The invention relates to the technical field of grain storage and transportation, in particular to a spiral material elevator used for grain storage and transportation. Background technique [0002] When grain is loaded into the granary for storage and loading and transportation, a hoist is required. The spiral material hoist is a kind of hoist, which drives the screw auger to rotate through the motor, so as to realize the lifting of the material. Compared with the existing crawler elevator commonly used in grain storage and transportation, since the spiral material hoist can achieve material lifting with a large inclination angle, such as vertical lifting, while the crawler elevator can only achieve material lifting with a small inclination angle, the lifting At the same height, the use of a spiral material elevator can effectively reduce the required floor space by realizing a large inclination angle of lifting, so it is more convenient to use.

Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcomings in the prior art, such as: but when the spiral material hoist is used for grain storage and transportation, the interior of the grain will be damp due to moisture during the storage process, so that sticking and agglomeration will occur Therefore, during the lifting process, it is easy to increase the resistance to the rotation of the auger due to the adhesion of wet grain materials to the auger and the inner wall of the hoist. If it is more serious, it may even cause blockage, thereby affecting To the normal lifting of grain materials by the spiral material hoist
