Abstract
The invention relates to a seed-metering device in agricultural machinery and provides a seed-filling ditch-type precision seed-metering device. The device consists of a seed box, a seed filling wheel, a seed guide side plate, a hairbrush and a seed cleaning piece, wherein a seed filling groove, a seed-metering stopper and a seed cleaning gap are formed in the seed filling wheel; a seed guide groove is formed in the seed guide side plate; the seed filling groove is formed in one side of the seed filling wheel; the seed filling groove is connected with the seed guide side plate, and the side surface of the seed-metering stopper is arc-shaped; the joint of the part, which is positioned in the seed box, of the seed guide side plate and the seed filling wheel is arc-shaped; a ditch is formed between the side surface of the seed-metering stopper in the seed box and the seed guide side plate; and a seed guide groove is formed in one side, which is close to the seed guide side plate, of the seed cleaning piece in the seed cleaning gap.
Description
Technical field
The present invention relates to the dispenser in agricultural machinery.
Background technology
Precision drilling reasonably can arrange seed, reaches and saves seed, Appropriate application soil fertility, sunlight and wind-force, obtain good procreation enviroment, coordinates individual and group relation, realizes the percentage of earbearing tiller high, individual plant fringe is many, grain is many, full, thus reaches the object of high yield.Precision Seeding culture technique only could put into practice in large area by means of the sower of function admirable.Precision drilling machineryization technology has the advantages such as province's kind, saving of labor, energy-conservation, high yield.Wheat is one of China's staple food crop.The wheat cultivation amount of broadcasting is large, spacing in the rows is little, and existing Wheat Precision Metering Device is owing to filling the restriction of kind of time, and speed of drilling is low, and percentage of damage is higher, and it is fluted-roller feed mechanism that present wheat seeder commonly uses seeding unit.But due to fluted-roller feed mechanism structure caused by, when seeding quantity is less, seed flow is pulsation phenomenon, and uniformity is affected.Therefore, design one fills kind of a ditch formula precision seeder, plants be significant for raising seeding uniformity, volume increase, province.This mechanical type dispenser is applicable to the small-sized seed broadcasting similar wheat, Chinese sorghum, millet (hybrid millet) etc.
Summary of the invention
The invention provides one and fill kind of a ditch formula precision seeder.This device by kind of a box, to fill kind wheel, lead kind of a side plate, hairbrush, seed cleaning sheet form, fill kind of wheel has and fill kind of a groove, seeding catch, plant gap clearly, lead on kind of side plate and have seed guiding groove.
The technical solution adopted for the present invention to solve the technical problems is: fill kind of groove and to fill kind a wheel side, fill above kind of groove, side all can fill kind; Fill kind of groove and lead kind of a side plate and connect, seeding catch side is arc; Lead the part of kind of side plate in kind of box and fill that kind to take turns joint be arc; In kind of box seeding catch side with lead kind of a side plate and form a ditch; Seed cleaning sheet in clear kind of gap has a seed guiding groove near leading kind of a side plate side.
The invention has the beneficial effects as follows: to plant in box seeding catch side and lead kind of a side plate and form a ditch, seed can be arranged into a line; To fill kind wheel to rotate, it is motionless to lead kind of side plate, promotes that filling kind of a groove fills kind; Leading kind of side plate with filling kind of a groove joint is arc, is imported from the side by seed and fills kind of a groove; Fill kind of a groove both-side opening, seed is more easily entered and fills kind of a groove; Seeding catch is thinner, seed is more easily entered and fills kind of a groove; Seed guiding groove avoids seed be stuck in seed cleaning sheet and lead kind of a side sheet room, and has certain guiding function to the fall trajectory of seed.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example, the present invention is further described.
Accompanying drawing 1 is structure chart of the present invention, and accompanying drawing 2 is cutaway views.
In Fig. 1, a kind of box 2 fills kind of groove 3 seeding catch 4 hairbrush 5 seed cleaning sheet 6 and fills kind of wheel 8 seed guiding grooves in kind gap 7 clearly, and in Fig. 2,9 lead kind of a side plate.
Embodiment
Plant box (1) interior Some seeds in the accompanying drawings to enter seeding catch (3) side and lead in ditch that kind of a side plate (9) formed, fill kind of a wheel (7) when to fill kind to rotate, fill kind of a groove (2) upside seed to fall into by gravity and fill kind of a groove (2), or the seed in ditch fills kind of a groove (2) by the arc importing led on kind of a side plate (9), makes seed arrive hairbrush (4) and is filled with kind of a groove (2) before; Arrive hairbrush (4) leading kind of side plate (9) removing and fill kind of a groove (2) side seed, the seed filled above kind of a groove (2) removed by hairbrush (4), filling kind of a groove (2) interior seed or directly being derived by the seed cleaning sheet (5) of planting clearly in gap (6) and fill kind of a groove (2) by hairbrush (4), or is released from the side by seed cleaning sheet (5) and fill kind of a groove (2) along seed guiding groove (8) discharge.
Claims (3)
1. fill kind of a ditch formula precision seeder, this device by kind of a box, to fill kind wheel, lead kind of a side plate, hairbrush, seed cleaning sheet form, fill kind of wheel has and fill kind of a groove, seeding catch, plant gap clearly, lead on kind of side plate and have seed guiding groove, it is characterized in that: fill kind of groove and filling kind of a wheel side.
2. according to claim 1ly fill kind of a ditch formula precision seeder, it is characterized in that: seeding catch side is arc.
3. according to claim 1ly fill kind of a ditch formula precision seeder, it is characterized in that: lead the part of kind of side plate in kind of box and fill that kind to take turns joint be arc.
