A new type of adjustable grain impurity removing machine by air selection

Abstract

This utility model discloses a novel wind-separated adjustable grain cleaning machine, including a loading host. A first scattering bucket is inserted into the lower part of the loading host at both ends, with a first bottom plate at one end of the first scattering bucket. A second scattering bucket is located inside the first scattering bucket, with a second bottom plate at one end of the second scattering bucket. The first and second scattering buckets are respectively located within the loading host, and a rotating column and a rotating tube are inserted into each bucket. A first angular gear is sleeved in the middle of the rotating column, and a second angular gear is located at one end of the rotating tube. The first and second angular gears mesh symmetrically with each other below a third angular gear. A motor is located at the outer end of the rotating column. By utilizing the reversible rotation of the first and second scattering buckets, a large amount of grain is scattered after being poured in, preventing grain from piling up. Subsequent wind-driven sieving removes impurities and outer shells, increasing the quality of sieving.

Description

Technical Field

[0001] This utility model relates to the field of grain cleaning machine technology, specifically to a novel adjustable air-separated grain cleaning machine. Background Technology

[0002] A grain cleaner, also known as a grain screening machine, is a type of grain screening machinery suitable for cleaning and screening cash crops such as corn, wheat, peanuts, soybeans, rice, millet, cotton seeds, and camellia seeds. After harvesting, grain is screened to remove impurities mixed in, facilitating storage or processing. Existing air-separated grain screening equipment involves directly pouring in large quantities of grain and then using airflow to remove impurities and husks. However, this large-scale pouring causes grain to clump together, making it difficult to screen thoroughly and resulting in low-quality grain screening. Therefore, a new type of adjustable air-separated grain cleaning machine is proposed to address these issues. Utility Model Content

At the same time, the air collection box 16 is provided with a wind-powered discharge assembly 17 on the other side above it.

[0028] A wind collection box 16 is provided below the main feeding unit 1, and a wind-powered discharge assembly 17 is connected above the wind collection box 16. The wind-powered discharge assembly 17 is used to perform wind separation on the falling grain, so that impurities are blown out from above the wind-powered discharge assembly 17.

[0029] Working principle: A first spraying bucket 2 and a second spraying bucket 3 are respectively provided inside the loading host 1. A first bottom plate 201 and a second bottom plate 301 are respectively provided at one end of the first spraying bucket 2 and the second spraying bucket 3. A first ring block 203 and a second ring block 303 are respectively provided at the outer ends of the first bottom plate 201 and the second bottom plate 301. The first ring block 203 and the other end of the first spraying bucket 2 are respectively placed inside the inner wall of the loading host 1, allowing the first spraying bucket 2 to rotate inside the loading host 1. The second ring block 303 and the other end of the second spraying bucket 3 are respectively placed inside the inner side of the first bottom plate 201 and inside one side of the inner wall of the loading host 1, allowing the second spraying bucket 3 to rotate inside the first spraying bucket 2. A fixed connecting rotating column 4 passes through the middle of the first bottom plate 201, and both ends of the rotating column 4 pass into the inner walls of the two sides of the rotating connecting loading host 1. A fixed connecting rotating tube 5 is inserted into the middle of the second bottom plate 301. One end of the rotating tube 5 has a section of the rotating column 4 inserted into it so that the two do not interfere with each other when they rotate. The first angular gear 6 on the rotating column 4 and the second angular gear 7 on the rotating tube 5 are symmetrically arranged, and the first angular gear 6 and the second angular gear 7 simultaneously mesh with the third angular gear 8. At the same time, the outer end of the rotating column 4 is connected to the motor 11 for driving. When a large amount of grain is poured into the feeding host 1, the motor 11 is started to make the rotating column 4, the first angular gear 6 and the first spreading bucket 2 rotate. Through the transmission of the third angular gear 8, the second angular gear 7, the rotating tube 5 and the second spreading bucket 3 reverse. At this time, the first grid part 202 on the inner wall of the first spreading bucket 2 and the second grid part 302 on the inner wall of the second spreading bucket 3 reverse each other, scattering a large amount of grain, and some grain also falls from the first grid part 202 and the second grid part 302. Then, a large amount of grain falls down when it enters the discharge port 14.
