The air supply pipe 105 is a four-way pipe and is inserted into the primary screening box 101, and spray heads are fixedly arranged on the outer sides of the four-way pipe.
The rotating shaft 301 is rotatably installed in the rotating shaft clamping frame 204, and the positions, close to the ineffective spike outlet 106 and the effective spike outlet 107, in the primary screening box 101 are respectively provided with a chute 109. The fallen rice ears are collected through the chute 109, so that the situation that the rice ears stay at the outlet position and cannot fall out is avoided.
When the rice effective ear detection device is used, through the cooperation of the blast pipe 105 and the partition plate 108, hot air can be blown into the primary screening box 101 through the blast pipe 105 when the device is used for detecting rice ears, so that the hot air blows lighter ineffective ears to one side of the ineffective ear outlet 106, and heavier effective ears cannot be blown and fall into the effective ear outlet 107, thereby completing the first-step screening of rice ears;
Through the cooperation of the re-screening mechanism 2 and the ear pressing mechanism 3, when the first step screening of the rice ears is completed, the situation that part of the effective ears drop into the ineffective ears together when the effective ears are moved by the ineffective ears when the effective ears drop occurs, and the situation that part of the effective ears enter the ineffective ears together due to errors in wind power control also occurs, so that water can be injected into the interior of the re-screening box 201 at first, the water level is maintained at the height position of the water level 205, then the ineffective ears detected by the primary screening mechanism 1 can be discharged into the interior of the re-screening box 201 through the auger conveying mechanism 4, so that the rice ears mixed with the effective ears drop into water through the re-screening inlet 202, at the moment, the servo motor 304 is controlled to drive the rotary shaft 301 to rotate, the pressing plate 302 is driven to rotate in the interior of the re-screening box 201, the pressing plate 302 presses the rice ears and pushes the lower position of the water level, and the effective ears are separated from the ineffective ears due to the fact that the hollow structure of the ineffective ears upwards, the effective ears downwards due to the grains filled in the interior of the effective ears are concentrated into the water level, the effective ears are separated from the ineffective ears, the effective ears can float back to the upper position of the effective ears after the effective ears float upwards, and the effective ears float back to the water surface again, and the effective ears float upwards to the position of the effective ears are screened;
Through the cooperation of the air supply pipe 105 and the auger conveying mechanism 4, when the device finishes secondary screening of rice ears, the auger conveying mechanism 4 can throw the secondarily screened effective ears back into the inside of the material separating table 103, at the moment, a pressure release valve of the re-screening outlet 203 is opened, so that part of water and the effective ears are conveyed into the inside of the material separating table 103 through the auger conveying mechanism 4, at the moment, the effective ears and the water roll into the inside of the primary screening feed port 102 through the inclined surface of the material separating table 103, at the moment, the water is discharged out of the material separating table 103 through the filter screen 104, so that the moist effective ears fall into the inside of the primary screening box 101 through the primary screening feed port 102, and therefore, the moist effective ears can be dried through hot air blown out of the air supply pipe 105, and part of the effective ears are pressed to fall into the re-screening outlet 203 together, so that repeated screening and drying operations of the effective ears are finished, and missing or false selection of the effective ears are avoided;
Through the cooperation of dividing table 103 and filter screen 104, make dividing table 103 when carrying the rice ear to the inside of primary screening case 101, accessible filter screen 104 spills the silt that mixes in the rice ear, avoids its screening that influences the rice ear to can discharge the water in the rice ear after the secondary screening, avoid water to get into the inside of primary screening case 101.
