Referring to fig. 1-4, the present invention provides a technical solution:

a seed screening device for agricultural production comprises a lower charging barrel 1, a bottom plate is arranged at the bottom end of the lower charging barrel 1, the stability of the lower charging barrel 1 is improved, the lower charging barrel is not prone to toppling, a feeding hopper 2 is installed at the top end of the lower charging barrel 1, a seed scratching wheel 10 is installed inside the feeding hopper 2 in a rotating mode, the seed scratching wheel 10 is composed of a roller and a plurality of scratching plates, the scratching plates are evenly installed on the outer wall of the roller, the seed scratching wheel 10 is located at an outlet of the top end of the feeding hopper 2 and rotates at a constant speed, seeds are poked to an outlet position in batches and fall down, the falling speed of the seeds can be controlled by controlling the rotating speed of the seed scratching wheel 10, incomplete screening caused by the fact that the seeds fall too fast is avoided, a speed reduction driving mechanism which drives the seed scratching wheel 10 to rotate is installed on the outer wall of the lower charging, one end of the seed marking wheel 10 is connected with a rotating shaft extending to the outer side of the feed hopper 2, a first gearwheel 11 is mounted at the end part of the rotating shaft, a second gearwheel 14 and a second pinion 15 which are positioned between the first gearwheel 11 and the first pinion 13 are coaxially mounted on the outer wall of the lower feed barrel 1, the first pinion 13 is meshed with the second gearwheel 14, and the second pinion 15 is meshed with the first gearwheel 11.

After the motor 12 is started, the rotating speed of the output shaft of the motor 12 is reduced through a plurality of meshed gears, so that the seed-rowing wheel 10 rotates at a proper rotating speed, the seeds are controlled to slowly fall, and the falling seeds can be fully screened.

Install the box 3 of blowing with 1 intercommunication of lower feed cylinder on the outer wall at 1 top of lower feed cylinder, the front end of blowing box 3 is equipped with solid fixed ring, gu fixed ring installs on the outer wall of lower feed cylinder 1 through a plurality of fastening bolt, and set up the air intake that corresponds with 3 positions of blowing box on the outer wall of lower feed cylinder 1, make things convenient for dismouting to blow box 3 and maintain, a plurality of fans 5 are evenly installed to the inside of blowing box 3, install the control button 4 of all being connected with every fan 5 on the roof of blowing box 3, through the power of every fan 5 of control button 4 control, adjust wind-force, this technique has very extensive application in the present stage, do not do here and describe repeatedly. One side that lower feed cylinder 1 deviates from blowing box 3 is equipped with the waste material mouth 6 with lower feed cylinder 1 intercommunication, and waste material mouth 6 highly corresponds with blowing box 3, inclines to be connected with out kind of groove 9 on the lateral wall of lower feed cylinder 1 bottom.

One side of the charging barrel 1 is provided with a water tank 7 positioned below the waste port 6, and a filter basket 8 is arranged inside the water tank 7.

The working principle is as follows: after the power of opening equipment, pour the seed that will need the screening into feeder hopper 2 in, the seed receives stirring of rowing wheel 10 and falls down feed cylinder 1 evenly, is blown by the wind that blows off of box 3 of blowing, and the seed proportion of shriveling is lighter, is blown to in waste material mouth 6 and finally drops, and full seed proportion is great to drop and finally falls out from play kind of groove 9. The seed that drops from scrap receptacle 6 has the part probably to satisfy the requirement of making into the cultivation seed, consequently catches it through filtering basket 8, and the seed that the shrivelled then floats at the surface of water, clears up floated seed, then takes out the seed that filters basket 8 and will collect and weather and can process.
