Description

A kind of pneumatic transporting kind seeding apparatus

Technical field

The utility model relates to a kind of seeding apparatus of sower, and especially a kind of seeding apparatus relying on pneumatic transporting kind, belongs to agricultural machinery technological field.

Background technology

Sower is widely used in agricultural production, and what its seeding apparatus great majority adopted is mechanical seed sowing device, as fluted-roller feed mechanism, shape cellular type seeding unit etc.Adopt the seeding apparatus of mechanical seed sowing device, normally by kind of a case, be arranged on kind of a seeding unit for case lower end, the seed delivery soft pipe be connected with seeding unit seed export, and the grain tube be connected with seed delivery soft pipe forms.During this seeding apparatus seeding operation, by the effect of seeding unit the colony of seed turned to individuality or turn to uniform seed flow, the seed of discharging from seeding unit relies on self gravitation to drop into large Tanaka by seed delivery soft pipe and grain tube.

Prior art adopts the seeding apparatus of mechanical seed sowing device, due to seed leave seeding unit after be rely on self gravitation flow in seed delivery soft pipe and grain tube, so the structural allocation of seeding apparatus on sower is restricted, one is the top that each seeding unit of requirement will be in corresponding grain tube as much as possible, two is that seed delivery soft pipe will be in comparatively precipitous heeling condition, this just makes the transversary size of kind of case large (being close to consistent with the sowing fabric width of sower), and require that kind of case is configured in the top of the afterbody near facility, thus the center of gravity of whole facility can be caused to the rear higher, reduce facility walking mobility.Therefore, the mechanical type seeding apparatus of prior art is used on seeding machinary, is particularly used in the upper structural allocation difficulty of the seeding machinary (as rotary tillage fertilizer) with multiple operation function.

In addition, existing mechanical type seeding apparatus is used to sow, it is uneven that seed lands rear density, discreteness is bad, and the growth of the seed concentrated in together to crop is unfavorable, directly can have influence on quantity and the quality of individual plant crop fringe grain, be unfavorable for increasing Basic Seedling quantity to improve the well stimulation of per mu yield.

Summary of the invention

For the deficiency that the mechanical type seeding apparatus of prior art exists, primary and foremost purpose of the present utility model is, proposes a kind of seeding apparatus can being convenient to configure on facility.

Secondary objective of the present utility model is, the seeding apparatus proposed can evenly be sowed discretely, is beneficial to improve crop yield by increasing Basic Seedling quantity.

For realizing above-mentioned primary and foremost purpose, a kind of pneumatic transporting kind seeding apparatus that the utility model proposes, comprise kind of a case, mechanical seed sowing device, seed delivery soft pipe and grain tube, mechanical seed sowing device is arranged on the bottom of kind of case, seed delivery soft pipe is connected with grain tube, its structure is improved and is: also comprise blower fan and defeated kind of device, defeated kind of device is by casing, the blast pipe be integrally connected with casing, enter kind of pipe and seed output pipe composition, blast pipe is given a dinner for a visitor from afar the air outlet of machine, the bottom entering kind of pipe is inserted into the top of seed output pipe with leaving radial clearance, the lower end outlet of the upper end import and seed output pipe that enter kind of pipe is connected with seed delivery soft pipe with the sowing port of seeding unit respectively.

The further improvement of a kind of pneumatic transporting kind seeding apparatus that the utility model proposes is, defeated kind of device to enter the radial clearance that kind of pipe inserts seed output pipe part be 2 ~ 4mm, intubating length is not less than 2 times into kind of pipe diameter.

For realizing above-mentioned secondary objective, the further improvement of pneumatic transporting kind seeding apparatus of the present utility model is, grain tube is the up-small and down-big conical pipe in cross section

Compared with prior art, the utility model adds blower fan and defeated kind of device, and grain tube is made the up-small and down-big conical pipe in cross section, rely on the good effect that Geldart-D particle seed produces, one be can reduce kind of case transversary size and can long distance delivery seed, thus can without restriction seeding apparatus be configured on the correct position of facility; Two is can produce negative pressure in the exit of seeding unit, eliminates because seed causes the discontinuous phenomenon going out to plant in exit delay, improves the uniformity of sowing; Three is under the impact of air-flow, and in conjunction with tapered grain tube, seed lands rear easy formation even discrete distribution, the seed belt of width 6 ~ 10cm, and then can increase seeding quantity, is conducive to improving output.

Embodiment

Embodiment one

As shown in Figures 1 to 4, the pneumatic transporting kind seeding apparatus of the present embodiment, forms primarily of kind of case 1, mechanical seed sowing device 2, seed delivery soft pipe 4, the grain tube 5 be connected with seed delivery soft pipe lower end, blower fan 6 and the defeated kind of device 3 be arranged on bottom kind of case 1.This defeated kind of device 3 by casing, the blast pipe 31 be integrally connected with casing, enter kind of pipe 32 and seed output pipe 33 forms, blast pipe 31 is given a dinner for a visitor from afar the air outlet of machine 6, the bottom entering kind of pipe 32 is inserted into the top of seed output pipe 33, intubating length is 40mm, radial direction leaves 4mm gap between the two, and the lower end outlet of the upper end import and seed output pipe 33 that enter kind of pipe 32 is connected with seed delivery soft pipe 4 upper end with the sowing port of seeding unit 2 respectively.Grain tube 5 is the up-small and down-big conical pipe of sectional area.Because seed relies on strength to flow in seed delivery soft pipe 4 and taper grain tube 5, so seed can be carried over long distances, but also seed can be realized land the seed belt of the even discrete distribution of rear formation.
