Description

A kind of absorption type duplicate rows seeding unit

Technical field

The utility model relates to a kind of seeder by the gas absorption seed, belongs to the agricultural seeder apparatus.

Background technology

At present, agricultural seeder has been realized mechanization substantially, and sower of a great variety is to adapt to the needs that Different Crop, different region, different sowing require.In numerous sowers, the mechanical type sower uses the earliest, is most widely used, and has made contribution for realizing the mechanization of farm work.But be to use middle discovery, the mechanical type seeder at seeding time seed directly by seeding, protect kind of parts and force to discharge, therefore these parts will be run into seed inevitably, the seed phenomenon is knocked in generation, particularly deviation is arranged slightly when the gap adjustment of parts, or transmission device is when unstable, knocks seed, to hinder seed even more serious, influence seeding quality and emerged, caused the underproduction.Another kind of sower is the air-sucking type seeder, it has overcome the shortcoming of mechanical type seeder, utilize the negative pressure of air-breathing generation that seed is inhaled on seed plate, then along with seed is discharged in the rotation of seed plate, this air-sucking type seeder has injuring-free seed, does not knock the advantage of seed, not broadcast leakage, is subjected to the welcome of vast farmers.But the air-sucking type seeder that widely uses all is the single file sowing at present, and efficient is low, and complex structure, changes the seed plate complex operation, and improved necessity is arranged very much.

Summary of the invention

Technical problem to be solved in the utility model provide a kind of simple in structure, easy to operate, can improve greatly the sowing efficient absorption type duplicate rows seeding unit.

The technical scheme that solves the problems of the technologies described above is:

Embodiment

Show among the figure that this absorption type duplicate rows seeding unit is made up of induction chamber 1, power transmission shaft 2, seed box 3, seeds sucker 4.

Two independent cavity about its induction chamber 1 is divided into, the air entry 5 of two chambers are pooled to a place and are connected with external vavuum pump.The chamber of induction chamber 1 connects the air-breathing groove 7 of circular arc, and the upper end of air-breathing groove 7 is communicated with air entry 5, and the lower end closed of air-breathing groove 7 has sowing port 8 in sealing place.The catch that can seal in addition in the junction of the chamber of induction chamber 1 and air-breathing groove 7, when needs carry out the single file sowing, can be with air-breathing groove 7 sealings of a side.

Its power transmission shaft 2 is connected with the tumbler of outside, drives power transmission shaft 2 and rotates.Above-mentioned transmission device is positioned at a side of seeding unit, and power transmission shaft 2 penetrates from a side and arrives two air-breathing chambers, drives two seeds suckers 4 in the chamber respectively and rotates.The side that power transmission shaft 2 and transmission device are positioned at seeding unit makes the structure of seeding unit become very simple, changes seeds sucker 4 and keeps in repair all very convenient.

Seed box 3 is two, be installed in the outside of two induction chambers 1 respectively, the box body periphery of seed box 3 is fastenedly connected with induction chamber 1 outward flange, the box body chamber is connected with air-breathing chamber, seed is put into from seed box import 6, get kind of mouth 15 in the lower end of seed box, unnecessary seed can be taken out after sowing finishes.

Seeds sucker 4 is two, lay respectively between the chamber of the chamber of two seed boxs 3 and induction chamber 1, the inner surface of seeds sucker 4 closely contacts with the chamber lateral surface of induction chamber 1, promptly is close to the outside of air-breathing groove 7, and seeds sucker 4 centers have axis hole 9 and power transmission shaft to be connected.The surface of seeds sucker 4 has inhales hole 9, inhales hole 9 and evenly distributes along the circumference of seeds sucker 4, inhales distance between the hole 9 and be the interseminal distance when sowing, inhale hole 9 circumferential positions relative be circular-arc air-breathing groove 7.The central authorities of seeds sucker 4 also have a seed adjustment dish 11, and seed adjustment dish 11 is coaxial with seeds sucker 4, are fixed on seeds sucker 4 side in the face of seed box 3 chambers, have a plurality of protrudingly 12 on the seed adjustment dish 11, and its effect is the seed of stirring when rotating in seed box 3 chambers.On seeds sucker 4, also has seed adjustment bar 13, seed adjustment bar 13 is a stock, and the centre has rotating shaft to pass the card of seeds sucker 4, at the other end of card locking nut 14 is arranged, its effect can pull out seed adjustment bar 13 with being adsorbed on seed unnecessary on the seeds sucker 4 by adjusting the position of seed adjustment bar 13.

The utility model is in when work, and vavuum pump is outwards air-breathing from air entry 5, and the air of the induction chamber 1 of air entry 5 both sides discharges, with the air-breathing groove 7 generation negative pressure in the induction chamber 1 that air entry 5 is communicated with.Because seeds sucker 4 is close to air-breathing groove 7 outer surfaces, the suction hole 9 of seeds sucker 4 is facing to air-breathing groove 7, air in seed box 3 chambers is sucked into air-breathing groove 7 by inhaling hole 9 under the effect of above-mentioned negative pressure, the air driven seed moves together simultaneously, and seed will be attached to be inhaled on the hole 9.

When vavuum pump was air-breathing, actuator drives power transmission shaft 2 rotated, and the seeds sucker 4 that power transmission shaft 2 drives both sides simultaneously rotates.At this moment be adsorbed with seed on the suction hole 9 on the seeds sucker 4, when seeds sucker 4 turned to sealing place of air-breathing groove 7, the back side in the suction hole 9 of seeds sucker 4 had not had air-breathing groove 7, just can not be subjected to the effect of the negative-pressure air-flow of induction chamber 1.And the position of sowing port 8 just is located at this sealing place, inhales the seed of absorption on the hole 9 and will realize seeding owing to the effect of gravity is fallen down when forwarding sowing port 8 positions to seeds sucker 4.
