Adjustable quantitative seeder

Abstract

The invention relates to the field of manual seeding tools and particularly provides an adjustable quantitative seeder. The adjustable quantitative seeder comprises a barrel, a seed hopper, a seedingquantity adjusting mechanism, a gate mechanism, a turning plate mechanism and a duckbill mechanism, wherein the seeding quantity adjusting mechanism comprises an adjusting plate, adjusting nuts and adjusting bolts; the gate mechanism comprises a gate unit, a switch plate and a spring; the gate unit comprises a gate, vertical sliding rods and first connecting rods; the turning plate mechanism comprises a turning plate, first cranks, a spring piece, a movable handle, a torsional spring and a second connecting rod; and the duckbill mechanism is arranged at the lower end of the barrel and comprises a first duckbill body, second cranks and a third connecting rod. The adjustable quantitative seeder provided by the invention achieves quantitative and adjustable seeding of seeds, and achieves holedigging and seed discharging at the same time, so that the adjustable quantitative seeder is convenient to operate and high in efficiency.

Description

technical field [0001] The invention relates to the field of manual seeding tools, in particular to an adjustable quantitative seeder. Background technique [0002] Hole sowing is to sow seeds after digging pits on the furrow surface of the field, and then cover them with soil. One or several seeds can be sown in each hole, which are called single-seed precision sowing or multi-seed hole sowing. It is suitable for corn, cotton, sugar beet, sunflower, beans, etc. , peanuts and other crops. The quantity of sowing is related to the yield of crops, and the quantitative seeder is beneficial to improve the efficiency of quantitative sowing and reduce labor intensity. [0003] CN208624079U discloses a Lancer hand-held seeder, comprising a support frame, a handle, a seed bucket, a quantitative seed taking mechanism and a seeding disc, the seed bucket is fixed on the support frame, the handle is fixedly connected to the support frame, and the quantitative seed taking mechanism is co...

AI Technical Summary

Problems solved by technology

The portable seeder has the following disadvantages: (1) the portable seeder adopts the cooperation of the seed control assembly and the leaking hole, and realizes the overlapping and separation of the rotating piece and the seeding hole by rotating the handle, thereby controlling the sowing of seeds. Therefore, When the rotary piece is separated from the leaking hole, the seeds will continue to enter the sowing cylinder from the seed box, and the operator can control the sowing amount based on experience, and quantitative sowing cannot be achieved; (2) When the sowing foot is blocked, use the foot to step on the foot The rod and the pedal rod drive the mud scraper to scrape off the clogged soil. After retracting the feet, under the tension of the spring, the pedal rod and the mud scraper reset. Since the shape of the mud scraper is the same as that of the sowing angle, the mud scraper Plates are also prone to clogging with mud
