Description
Technical field
The utility model relates to the technical field of seeding devices of sower.
Background technology
Seeding unit is the critical component on the sower, and its function is exactly that the seed of planting in the case is discharged by agriculture requirement, and its service behaviour directly affects the operation quality of whole sower.Present domestic precision seeder mainly contains mechanical type and pneumatic type two classes.Because the physical characteristic of the fine grain crops self such as millet, rape, sesame: the seed bodily form is little, thousand quality are little, out-of-shape.Thereby cause existing seeding unit can not realize well its precision metering device, in the seeding process because the problems such as the material of seeding unit, structure easily cause seeding unit to stop up or seed is rolled, the problems such as pulverizing, can not satisfy the specification requirement of fine grain crop precision drilling, thereby increase the labour intensity of later stage thinning and field management.Therefore design a kind of precision seeder to raise labour efficiency, to improve seeding quality and crop yield becomes the task of top priority.
The utility model content
The technical problem that the utility model solves is to reduce to hinder to plant and blockage problem, realize a kind of needle-based pneumatic seeding of the pressure of evenly sowing, minimizing later stage thinning, its honeycomb shaft radial hole is equipped with sucking needle, under the effect of air chamber negative pressure and malleation, syringe needle realize to be inhaled kind, seeding, can reach the even precision drilling of fine grain crop, and the syringe needle dismounting, change convenient, seed to difformity and size all can carry out seeding, and versatility is better.
The utility model is to solve the problems of the technologies described above the main technical schemes that adopts to be: a kind of needle-based pneumatic seeding, comprise kind of case and air chamber end face, planting case and air chamber end face is fixed on the support body, it is characterized in that the air chamber end face also is slidingly matched with honeycomb shaft is sealed, be evenly equipped with eyelet on the circumference of honeycomb shaft, these eyelets are communicated with the air chamber of air chamber end face by the dark hole in the honeycomb shaft, and the air chamber of air chamber end face is divided into negative pressuren zone and zone of positive pressure two parts, and syringe needle radially is installed in the eyelet on the circumference of honeycomb shaft.
Dark hole in the described honeycomb shaft includes bottom eyelet and radial hole, their numbers equate and mutually corresponding, interconnect.
Better for the loose joint reassembling type between the eyelet on the circumference of described syringe needle and honeycomb shaft, so that change the syringe needle model.Can change different syringe needles according to kind of grain size and geomery, finish the seeding operation of Different Crop.
Be provided with drive transmission device between described honeycomb shaft and land wheel.
The beneficial effects of the utility model are:
The beneficial effects of the utility model are: compared with prior art, can effectively reduce and hinder kind and solve blockage problem, can better realize the precision drilling of fine grain crop, all can carry out seeding to the seed of difformity and size, versatility is good.The design of adopting aspiration and air-blowing to combine can not cause hinder kind, stifled kind, can improve the precision of charging seed of seed, guarantee crop field planting, decide strain, later stage does not need thinning, reduce labour intensity, improve crop yield, the effect of realized keeping a full stand of seedings strong sprout, volume increase gain.
Be described further below in conjunction with embodiment and accompanying drawing, but not as to restriction of the present utility model.
