Description

Inside fill outlet type hole vibration-type feed mechanism for seed

Technical field

The invention belongs to agricultural machinery, relates generally to a kind of mechanical feed mechanism for seed of type hole formula.

Background technique

Type hole wheel machine feed mechanism for seed be it is a kind of in provinces and regions such as Heilungkiang, the Jilin of northern China using many years for drought Field soybean, corn seeding operation feed mechanism for seed, due to the feature that its structure is simple, cheap and seeding operation performance is fine, The ownership with higher in agricultural production operation.But since it uses the setting on the outer round surface of seed wheel to fill kind Type hole, seed is filled in type hole from seed wheel circumferential exterior when filling kind, when seeding, the centrifugal force and seed that are rotated by seed wheel Self weight is discharged out of shaped hole of feed wheel, and seeding operation is filled in completion.Centrifugal force and self weight can not be relied in type hole when kind of grain is stuck When discharge, hole broadcast leakage is caused, must using rigidity or elastic Seed-cleaning tool by kind of grain at this time, mandatory scratch out of type hole digs up, Easily cause G failures, operation quality decline.Especially in recent years, traditional with the development of the accurate agronomic technique in China Outlet is filled outside, the type hole formula feed mechanism for seed of clear kind of pressure does not adapt to and meet the actual needs of production operation.

Summary of the invention

The purpose of the invention is needed aiming at the above-mentioned problems of the prior art in conjunction with precision agriculture production operation Ask, design a kind of new construction in fill outlet type hole vibration-type feed mechanism for seed, reach seeding operation precision is high, eliminate sowing G seed therefore Barrier, the purpose for reducing hole rate.

The purpose of the invention is achieved in that on the left and right end of cylinder outer barrel, sealing installation is left respectively Cover board and right cover plate open up into kind of a mouth on right cover plate, open up sowing port on cylinder outer barrel bottom, drive shaft is rotatable It supports inserting on left and right cover board, annular slide track and arc-shaped seeds protecting plate is fixedly mounted in the right cover plate interior sidewall surface, described In drive shaft, column inner tub body is fixedly mounted in cylinder outer barrel barrel chamber, the bung hole end of the column inner tub body is rotatably inserted Enter configuration in annular slide track, the arc-shaped seeds protecting plate is located in column inner tub body at side wall surface, and cooperates, cylinder Inner drum is connected to kind of a mouth is entered, along the circumferential direction uniformly opened up on the cylinder side wall of the column inner tub body it is N number of fill kind of a mouth, with N number of the same number of N number of appearance kind cylinder of kind of mouth that fills is fitted on column inner tub body cylinder side wall outside, N number of to hold the interior of kind of cylinder Nozzle passes through N number of kind of mouth that fills correspondingly makes column inner tub body be interconnected respectively with N number of appearance kind cylinder, N number of appearance kind The outer end nozzle of cylinder cooperates with cylinder outer barrel inner wall in sealing, trapezoidal that interconnected being fitted in of kind of shell is taken to hold kind of a cylinder On body sidewall outside, it is fixedly mounted with vibration rod and push rod on the appearance kind cylinder outside portion, in the cylinder outer barrel interior sidewall surface On be fixedly mounted with fixed plate, support rod and gag lever post are packed in fixed plate, and folding bar is rotatably covered and fitted on support rod, torsion bullet Spring set fits on support rod, and the both ends of the torque spring are overlapped on respectively in fixed plate and folding bar, and the folding bar is successive Outlet type hole vibration-type seeding so far is filled in composition in contacting or disengaging cooperation with gag lever post, push rod, vibration rod respectively Device.

The invention uses column inner tub body after holding kind of a cylinder and making to be charged to trapezoidal take in kind of shell in seed, then will be terraced Shape takes the intracorporal seed of kind of shell by holding the sowing port extroversion discharge on kind of cylinder and cylinder outer barrel, and is promoted with vibration mode Seed has achieved the purpose that the invention from the trapezoidal structure for taking and being discharged in kind of shell, has structure novel, reasonable, operation It is high-quality, high-efficient, occur without G phenomenons, the feature that hole rate is low, meet and adapted to precision agriculture job requirements.
