Fig. 1 is a schematic structural view of the present invention.
Detailed Description
The invention will be further described with reference to the accompanying drawings.
As shown in figure 1, the grain screening agricultural machinery comprises a grain accommodating chamber 1, a screening hopper 2, a screening bin 11, an air suction channel 4, an upper blowing device 7 and a discharging channel 8; the grain accommodating chamber 1 and the screening hopper 2 are integrally arranged in the vertical direction, a screening plate 10 is arranged on a connecting interface of the grain accommodating chamber 1 and the screening hopper 2, an elastic reset device 3 is arranged on the outer wall of the screening hopper 2, a grain outlet is arranged at the bottom of the screening hopper 2, an upper blowing device 7 is arranged right below the grain outlet of the screening hopper 2, and a blanking channel 8 is formed by the conical outer wall of the upper blowing device 7 and the inner wall of the lower section position of the screening bin 11; a plurality of symmetrically arranged air suction channels 4 are communicated with the upper section wall surface of the screening bin 11; the bottom of the grain containing chamber 1 is symmetrically provided with a plurality of vertical vibrating devices 6, eccentric wheels of the vertical vibrating devices 6 are attached to the lower bottom surface of the grain containing chamber 1, and the grain containing chamber 1 can be driven to vibrate through rotation of the eccentric wheels, so that uniform screening and downslide of grain are realized.
The tail end of the air suction channel 4 is correspondingly provided with an air suction device 5, and chips in grain or light unqualified grains which are shrunken are sucked through the air suction device 5. The grain conveying device 9 is arranged below the blanking channel 8 and can convey qualified grain to a designated area.
The upper blowing end of the upper blowing device 7 is provided with a wind leakage plate, the wind leakage plate is provided with a plurality of wind leakage holes, the density distributed in the middle of the wind leakage holes is greater than that distributed at the periphery, and the aperture of the wind leakage holes is smaller than the grain size; the design of the distribution of the air leakage holes and the comprehensive effect of the grain flow at the grain outlet form air turbulence similar to a fountain form, so that chips in grain flow or light unqualified grains which are shrunken are picked out through air flow, and the grains are smoothly transferred out from the air suction channel 4 under the action of the air suction device 5.
The air leakage plate is arranged opposite to the grain outlet and keeps an adjustable distance; and the upper blowing device 7 is adjusted up and down, and the relative distance between the air leakage plate and the grain outlet is adjusted. The screening effect is better when the grain and the grain with different weights, densities, wind stress surface areas and the like are screened.
The screening plate 10 is provided with grain and grain refining holes, the aperture of the grain and grain refining holes is larger than the size of grain and grain, the distribution of the refining holes is sparse in the middle and dense in the periphery, and the design aims to ensure that fewer grains are directly and downwards tapered from the upper channel and the lower channel of the screening hopper under the conical cooperation of the inner wall of the screening hopper, ensure that as much grains as possible slide downwards along the periphery of the inner wall of the screening hopper, form hollow rings when as much as possible of downwards sliding grains reach a grain outlet, and prevent excessive grain radial falling from causing excessive interference to the air leakage plate and other bad factors. In the present invention, the sifting plate 10 may be replaced according to different kinds of cereal grains.
According to the invention, grain and food slide downwards from the screening hopper 2 under the condition of vibration and are discharged from a grain outlet, meanwhile, the air draft device and the upper air blast device 7 are started, a diffusion turbulent air flow is formed in the screening bin and the area between the air leakage plate and the grain outlet, the turbulent air flow causes impact force of diffusing from the center to the periphery on annular grain discharge flow of the grain outlet, the grain flow of the grain is blown away in an upward deflection direction, the blown away grain flow is diffused, and fragments or shrunken light unqualified grains in the diffused grains can be easily sucked away through an air draft channel communicated with the air draft device, and the qualified grains slide downwards from the conical outer wall of the screening hopper 2 to a preset grain transportation area.
