a seed length grading screening device applied to a rice breeding test comprises a rice ear threshing device 1, a seed winnowing device 2, a seed length grading device 3 and a grading accommodating box 4; the rice ear threshing device 1 is fixed above the grain winnowing device 2, the grain winnowing device 2 is internally provided with a grain bin 31 and a winnowing bin 32, the grain bin is communicated with the winnowing bin 32 through a seed leakage speed control shifting sheet 311, the side wall of the winnowing bin 32 is provided with a fan 6, the other side wall is provided with a shriveled grain discharging opening 312, and the bottom of the winnowing bin 32 is provided with a grain baffle 5; the other, the selection by winnowing storehouse bottom of real grain baffle 5 is equipped with real grain export, grain length grading plant 3 is located seed grain wind selector 2 below, and 3 below of grain length grading plant are equipped with hierarchical accepting box. The solid particle baffle is used as a boundary, the fan 6 and the solid particle outlet are arranged at one side, and the shrivelled particle outlet 312 is arranged at the other side; when the seed grain drops after threshing, the fan blows, and because the real grain is heavier then along the export of real grain of 5 landing of real grain baffle, flat grain is through arranging flat grain mouth by removing device.
The solid particle baffle 5 and the bottom of the winnowing bin 32 form an angle of 45 degrees, and the height of the solid particle baffle is 4/5 of the winnowing bin 32.
The grain length grading device is fixed below the winnowing device in a certain gradient, the surface of the grain length grading device is a gully-shaped grain length sorting slideway, and the side view of the grain length grading device is a W-shaped plurality of parallel grading plates; the grain length area 21 less than 4mm, the grain length area 22 between 4 and 6mm, the grain length area 23 more than 6mm and 3 screening areas are arranged on the screen.
The number of the grading holding boxes is 3, and the grading holding boxes are correspondingly arranged below the grain length grading device holes.
Ear of rice thresher 1 is fixed in seed grain wind selector 2 top, be used for threshing the ear of rice, fall into 2 seed storehouses of seed grain wind selector after threshing, open seed grain storehouse hourglass kind speed control plectrum, seed grain falls into the winnowing storehouse according to required speed, the fan blows, because the full degree of seed grain differs, the wind blows back flat grain is lighter along the 5 top discharge winnowing storehouses 32 of real grain baffle, real grain receives gravity factor then to follow real grain baffle 5 and slips out winnowing storehouse 32, fall into the hierarchical slide of grain length, the seed grain of different grain lengths slides at the slide, it falls into hierarchical containing box to correspond the grain length difference respectively by short and long corresponding hourglass hole of seeing through, accomplish the screening in grades.
Seed grain wind selector 2 is the open cuboid of lower extreme, and the circular-arc back landing of being convenient for the ear of rice to thresh of inner wall, and one side is 2mm clearance, stretches the clearance outer wall when ear of rice branch stalk, and the grain of rice is blocked at clearance inner wall, accomplishes to thresh. Seed grain wind selector 2 is cuboid case form, and box one side is fan 6, is built-in 45 real grain baffles to one side in the middle of the box, connects in winnowing bin 32 bottom, is located by real grain small opening, highly is 4/5 of box, and the box right side is for arranging flat grain mouth.
The 3 sides of the grain length grading device are regarded as W-shaped grading plates, a grain length area smaller than 4mm, a grain length area 4-6mm and 3 screening areas larger than the grain length area 6mm are arranged, the grain length grading devices are hung on the winnowing device at a certain gradient, the grain length screening device is a gully-shaped grain length sorting slideway, a plurality of groups of grain length grain falling holes are arranged in the groove from the higher gradient end to the lower gradient end, the grain length falling holes are respectively arranged at the width of 2.0mm, the length of the grain length grading devices is 2.1mm (for grains smaller than 4mm to fall), 2.6mm (for grains 4-6mm to fall), and 3.1mm (for grains larger than 6mm to fall).
