Self-discharging grain-unloading device

Abstract

The invention discloses a self-discharging grain-unloading device. The self-discharging grain-unloading device comprises a box body provided with a first grain unloading cavity and a second grain unloading cavity, a first auger for unloading stored grains in the first grain unloading cavity, a second auger for unloading stored grains in the second grain unloading cavity and a driving device for driving the first auger and the second auger; the first auger comprises a first rotary shaft, a first spiral plate and a first driven gear; the second auger comprises a second rotary shaft, a second spiral plate and a second driven gear; the driving device comprises a driving motor and a clutch linkage device; the clutch linkage device comprises a rack body, a transmission shaft, a clutch transmission gear, a belt pulley and a translational limiting piece; the clutch transmission gear is in screw joint to an external thread part of the transmission shaft; the clutch transmission gear moving to one end of the external thread part is in a first transmission station and the clutch transmission gear moving to the other end of the external thread part is in a second transmission station. The self-discharging grain-unloading device disclosed by the invention is relatively compact and reasonable.

Description

technical field [0001] The invention belongs to the technical field of logistics storage, and in particular relates to a self-unloading grain unloading device. Background technique [0002] The food problem is one of the urgent problems that attract worldwide attention. my country, as the most populous country in the world, consumes a large amount of food every year. Only with food can a country develop industry, national defense, service industry, scientific and cultural undertakings in a stable and healthy manner. The food issue is not only an economic and people's livelihood issue, but also a development and security issue. With the rapid development of green food and the continuous improvement of people's living standards, green grain storage technology has made great progress in our country. Under the guidance of "China's Grain Storage Ecosystem Theory System", my country's grain storage concept is undergoing profound changes. Grain storage technology is developing fro...

Problems solved by technology

[0003] At present, most of the traditional granaries adopt a single-body design, which can only store one kind of grain at the same time, and has a single function

There are also some granaries that adopt a double-body design, but use two separate sets of unloading devices to unload grain separately, resulting in the disadvantages of occupying a large area and high cost
