Rapeseed screening equipment for agricultural production and processing

Abstract

The invention discloses a kind of rapeseed screening equipment for agricultural production and processing in the technical field of agricultural production and processing, which includes a separation box, a screening box fixed on the right side of the separation box and a separation mechanism. plate and a blanking plate, the screening box is provided with a first fan, an air inlet channel, a collection chamber and a rotating chamber, and a rotating assembly is provided in the rotating chamber. Beat the straw through the detachment mechanism to detach the rapeseed, and fall to the material guide plate after the first screening of the detachment filter, and then move along the feeder plate for winnowing, so that the lighter slag, etc., enters The air inlet channel is thickly collected. After the rapeseed moves obliquely upwards, it falls to the lower right on the cutting board. The detachment, detachment screen screening and winnowing are completed continuously. The detachment is convenient and can prevent the rapeseed from contacting the bottom surface and contaminating more Dust is screened twice, with good screening effect and high work efficiency.

Description

technical field [0001] The invention relates to the technical field of agricultural production and processing, in particular to rapeseed screening equipment for agricultural production and processing. Background technique [0002] Rapeseed, also known as brassica, is the seed of rapeseed, a cruciferous crop. The siliques of rapeseed are long, have many pods, and the grains are full. The oil content in rapeseed is 37.5%-46.3%. The oil content varies slightly depending on the type of rapeseed. It is one of the main oil crops and honey crops in China, and its seeds are one of the main varieties of raw materials for making oil. [0003] Rapeseed is cultivated throughout China and is divided into two types: winter rapeseed and spring rapeseed. Its planting area accounts for more than 40% of the total oil crop area in China, and its output accounts for more than 30% of China's total oil crop output, ranking first in the world. [0004] The fruit of rapeseed is silique. The si...

Problems solved by technology

[0006] Before the rapeseed is pressed, if the soil, stems and leaves and other impurities in the rapeseed are not removed, it will not only affect the quality of the oil and cake, but also absorb part of the oil and reduce the oil yield

If the rapeseed contains sand, stone, metal, hemp rope and other debris, it will cause wear and tear of the machine parts, induce production accidents, and affect the process effect; therefore, in order to ensure the smooth progress of production, impurities must be removed as much as possible

[0007] The traditional method of rapeseed detachment is to spread rapeseed stalks on a flat field, and manually beat the straw with a special tool for beating rapeseed, that is, a flail, so that the rapeseed pods will explode, so that the rapeseed can be separated from the rapeseed. The separation efficiency is low, and it is easy to mix dust into the rapeseed, which increases the workload of subsequent screening; while the existing agricultural rapeseed screening device is usually a general-purpose winnowing machine, which is mainly composed of a feed hopper , fan, vibrating screen, etc., feeding through the hopper, removing impurities through the fan during the feeding process, and then falling on the vibrating screen to be screened again through the vibrating screen. This general-purpose air separator can be used for various crop seeds. Screening, its screening accuracy is low, and work efficiency is also low
