An agricultural rice selection device

Abstract

The invention discloses an agricultural rice seed selection device, which belongs to the technical field of agricultural machinery. The key points of the technical solution include an upper casing and a lower casing. A cover plate is arranged on one surface of the upper casing, and a plurality of springs are connected to the inner wall of the upper casing. One end of the spring is connected with a screening box, the surface of the screening box is provided with a number of screen holes, the inner wall of the screening box is also provided with a number of vibration devices, the surface of the lower case is provided with a number of switches, and the surface of the lower case is also provided with a number of ventilation holes, The inside of the lower shell is provided with a thermal insulation cavity, a separation cavity, a temporary storage box and a sterilization box. By using the screening box, the first motor and the fan blades, the seed selection equipment can screen the rice seeds multiple times, remove most of the impurities and shriveled rice seeds in the rice seeds, and improve the yield of rice seeds; by using the heat preservation chamber, it can Prevent the rice seeds from getting wet and germinate in advance; by using the separation chamber, the rice seeds can be stored directly after the selection is completed or further sterilized to remove harmful microorganisms and further improve the quality of the rice seeds.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and more specifically relates to an agricultural rice seed selection device. Background technique [0002] Seed cleaning machinery, which uses the differences in shape, size, specific gravity, surface characteristics and aerodynamic properties of seeds and inclusions to select qualified and high-quality seeds, including seed cleaning machines and seed selection machines. The seed cleaning machine is used to remove impurities from the seeds; the seed selection machine is used to select strong, plump and vigorous seeds from the cleaned seeds, and grade them according to the shape and size of the seeds if necessary. Most grain cleaning machines also It can be used for cleaning, sorting and grading of seeds. [0003] In the process of rice seed selection, it is often necessary to screen dry rice seeds or other impurities, and sometimes to carry out bacterial treatment. However, when s...

Problems solved by technology

[0003] In the process of rice seed selection, it is often necessary to sieve out dry rice seeds or other impurities, and sometimes to carry out bacterial treatment. However, when selecting rice seeds, it is often encountered that the removal of impurities is not sufficient, the seeds germinate early due to moisture, and the seeds have not been sterilized, etc. Problem, the present invention proposes a kind of agricultural rice selection equipment for above-mentioned problem
