Abstract

The utility model discloses a mechanical precise dibbling device which comprises a rotary drum constructed by a movable disc and a stationary disc; a seeding duckbill is arranged on a seed metering ring; the inner cavity of the rotary drum is divided into a seed chamber and a seed falling chamber by a separation disc; an inwards-concave circular annular seed taking channel is arranged on the circumference of the disc surface of the separation disc in the seed chamber; seed falling openings are uniformly distributed on the seed taking channel; crankshafts with turning plates are in uniform and radial distribution and are hinged with the circumferential surface of the separation disc in the seed falling chamber; a connecting arm is transversely and fixedly connected with the inflected bent part of each crankshaft, the outer end of each connecting arm is connected with a tension spring, and the other end of each tension spring is connected with the movable disc; the turning plates of the crankshafts in uniform distribution are matched with the seed falling openings one by one; the inflected end shafts of the crankshafts are matched with a control panel arranged on the cylindrical surface of the stationary disc at the inner side of the seed metering ring; seed taking spoons are uniformly distributed on the circumferential surface of the separation disc in the seed chamber; the spoon openings of the seed taking spoons correspond to the uniformly-distributed seed falling openings one by one. The mechanical precise dibbling device has reasonable structure, not only can realize precise seed taking and seed sowing, but also can realize reliable working performance and smooth seed metering, and avoids the situations of damaging and blocking seeds.

Description

The machinery precision drill

Technical field

The utility model belongs to the improvement of mechanical precision drill structure, particularly a kind of mechanical precision drill.

Background technology

Put a kind of roll-over formula precise seeder at present on market, its objective is the seeding unit that seeding quantity can accurately be controlled, during constituting, it comprises that housing, claw plate, inoculation dish, storehouse are every dish and power transmission shaft, inoculation dish and power transmission shaft are fixed, claw plate and inoculation dish are fixed, separator disc is located between claw plate and the inoculation dish to be had, and fixes with housing; Its weak point is to adopt claw plate to get that kind of mechanism can not accurately obtain simple grain or two seeds make seeding quantity be difficult to control precisely; in addition; at seeding time and relatively rotating of being produced between separator disc can damage seed; capsuled seed particularly; the surface is sent out puckery, wet tide, is very easy to be bonded at the surface of getting the feed mechanism of planting, and makes the resistance of seeding process too big; cause that seed gets stuck, fragmentation, broadcasting full stand to one has very big influence.

Summary of the invention

The purpose of this utility model is to provide a kind of mechanical precision drill, and it is rational in infrastructure, can realize that not only essence measures kind, precision drilling, and reliable working performance, and seeding is smooth and easy, the phenomenon of seed and card type can not occur damaging.

The purpose of this utility model is achieved in that a kind of mechanical precision drill, comprise by Moving plate that seeding circle and platen are housed and price fixing and constitute cylinder, on the uniform sowing port of seeding circle, the sowing duckbilled is being set respectively, separator affixed on the Moving plate inner face is separated into seed chamber and kind of the chamber that falls with drum cavity, the annular seed-taking channel that concaves is being set on the circumference of the separator card that is positioned at seed chamber, the uniform land kind mouth that is provided with on seed-taking channel, be the radial uniform articulated axle that turns that has turnover panel on the separator periphery of kind of chamber being positioned at, the crank throw bending part that turns axle laterally affixed linking arm, wherein the outer end of linking arm is connecting extension spring, the extension spring other end is connected on the Moving plate, a uniform turnover panel that turns cooperates one by one with uniform kind of the mouth that falls, the end axle that turns a crank throw matches with the control panel that is positioned at the setting of the inboard price fixing barrel surface of seeding circle, be positioned on the seed chamber separator periphery uniform the setting and get kind of a spoon, the uniform spoon of getting kind of spoon is mouthful corresponding one by one with uniform kind of the mouth that falls.

During sowing, seed is entered seed chamber from the seed inlet on the price fixing, cylinder is in advancing forward, and the Moving plate of rolling drives separator and gets kind of a spoon, and turns axle motion together.After getting kind of spoon and in seed chamber, getting kind, the rotation of follower disk, this is got kind of spoon and goes to certain angle, and get the corresponding end axle axial plane that turns a crank throw of corresponding kind of the mouth that falls of kind of spoon with this and contact with control panel, and along the line face generation relative motion of control panel, turnover panel is opened, this seed of getting kind of spoon enters in the sowing duckbilled by feed outlet, when the sowing duckbilled contacts with ground, sows the duckbilled punching of burying, seed falls in kind of the cave, finishes the course of work that an essence is measured kind of sowing.The utility model is rational in infrastructure, has realized that not only essence measures kind, precision drilling, and reliable working performance, and seeding is smooth and easy, the phenomenon of seed and card type can not occur damaging.
