Cereal lifting device

Abstract

This utility model discloses a grain lifting device, including a lifting machine casing. Two drive wheels are rotatably connected to the upper and lower ends of the inner surface of the lifting machine casing, respectively. The surfaces of the two drive wheels are connected by a first drive belt, and a grain transport box is fixedly connected to the first drive belt. A fan is installed on one side of the upper part of the feeding hopper of the lifting machine casing, and a dust collection box is installed on the other side of the upper part of the feeding hopper. The dust inlet of the dust collection box is directly opposite the fan. The outlet of the discharge hopper of the lifting machine casing faces downwards, and a sieve plate is installed at the outlet of the discharge hopper. This utility model sets up a fan and a dust collection box at the feeding hopper. When grain enters the feeding hopper, the fan can separate impurities from the grain, which will be stored in the dust collection box for easy cleaning. The grain enters the grain transport box and is conveyed to the discharge hopper, where the sieve plate further separates large impurities, achieving secondary impurity removal from the grain. This reduces dust from the grain during discharge, thus protecting the environment.

Description

Technical Field

[0001] This utility model relates to the field of grain processing technology, and in particular to a grain lifting device. Background Technology

[0002] After being received from farmers, grains need to undergo a series of processing steps to finally become finished rice. In the entire process of grain processing, lifting devices are often used to lift the materials. For example, when the grains are first transported to the processing plant, they need to be lifted very high and then divided into various large silos. After that, they fall out of the silos and are processed separately.

[0003] A grain elevator is a mechanical device used to vertically or inclinedly transport grain to a higher level. It is mainly used in grain production, processing, and storage. In grain processing plants, elevators transport raw grain from the raw material warehouse to the feed inlets of various processing equipment such as cleaning, grinding, and screening equipment, ensuring the smooth operation of the processing flow. However, current grain elevators generate a large amount of dust during discharge, which not only pollutes the environment but also poses a threat to the health of operators.

[0004] Therefore, there is an urgent need for a grain lifting device to solve the problems of dust pollution and threats to the health of operators. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a grain lifting device to solve the problems mentioned in the background art.

[0013] As a preferred embodiment, the inlet of the feed hopper faces upward, and a cover plate is installed at the inlet of the feed hopper, with a feed pipe provided on the cover plate.

[0014] In summary, compared with the prior art, this utility model has the following beneficial effects: This invention features a fan and a dust collection box at the feed hopper.
