Abstract
The present invention belongs to the field of agricultural machinery, and is especially one kind of seeder comprising a blower, an injector, a elbow, a pressurizing pipe, a distributor, etc. Under the driving of the high pressure airflow the centrifugal blower provides, the quantitative seed flow from the sowing slotted wheel and the high speed airflow from the injector form homogeneous mixture flow in the nozzle, and the homogeneous mixture flow is pressurized in the pressurizing pipe and distributed in the distributor. The present invention has relaxed requirement on the shape and size of seed, low seed damage, homogeneous seed sowing and other advantages.
Description
(1) technical field
The invention belongs to the agricultural machinery seeding apparatus.
(2) background technology
The development trend of seeding machinery is at present: improve operating rate, increase the farming fabric width, development is ploughed and is broadcast integration of operation, promotes the precise sowing technology.Existing seeding unit belongs to " a device delegation " form mostly.If operating rate improves, certainly will cause seeding environmental deterioration, seeding quality to reduce; If will increase the farming fabric width, then need be equipped with a plurality of seeding units, make that like this complete machine structure complexity is too fat to move, be unfavorable for developing the wide cut operation and broadcast integration of operation with ploughing.Centralized seeding unit or system (being called for short collection row device) are the forms of " a device multirow ".Problems such as many collection row devices of developing now are higher such as the percentage of damage that collection such as centrifugal, line disc type, inclined plate formula and cone disk type row device all can not well solve seed, each row uniformity coefficient of variation is big, the sowing line number is restricted, complex structure is too fat to move, thus limited their popularization.
(3) summary of the invention
The purpose of this invention is to provide a kind of requirement that can satisfy seeding quality, can the high speed operation, the better simply centralized seeding unit of structure.The present invention is carrier with the air-flow, and by the injection and the mixing of injector, branch's seeding of distributor is finished the seeding of " a device multirow ", thereby can be simplified complete machine structure, significantly improves operating efficiency, for precision, half precision and wide cut operation create conditions.
The present invention mainly is made up of blower fan, seeding batcher, receiving hopper, feed injector, bend pipe, pressure inlet, distributor, discharging tube etc.Wherein seeding batcher, distributor and blower fan are separately fixed on the corresponding shelf, and blower fan is by motor drives.
The present invention can replace the seeding unit of traditional " a device delegation ", realizes " a device multirow " seeding.The present invention is a transmitting power with the air-flow, in injector air-flow is mixed with seed and forms uniform gas kind mixed flow, by pipeline mixed flow is transported in the distributor, realizes the quantitative seeding of " a device multirow ".The present invention is less demanding to the geomery of seed, and the percentage of damage of seed is less, and each row discharge capacity uniformity coefficient of variation is less, and only about 1.5%, satisfy the requirement of GB.Simultaneously it can increase work efficiency, simplify complete machine structure exponentially, and better to the adaptability of high speed operation, so economic benefit and social benefit are obvious, apply and market prospects wide.

(5) preferred forms
The feed pipe (11) of the injector (4) that is processed by No. 45 steel is connected with securing member with the receiving hopper (9) of seeding batcher (1) below, the nozzle (10) of injector (4) is connected with the air outlet of blower fan (3), the carrier pipe interface (16) of injector (4) is connected with an end of bend pipe (5), belong to pressure inlet of the present invention (10) and be connected with the other end of bend pipe (5), the grain tube road (23) of distributor (7) is connected in the other end of pressure inlet (10).Circumference evenly processes kind of a mouth (18) in distributor (7) upper edge, discharging tube (8) with go out kind of a mouth (18) and be connected.The standard seal part is all used in the connection of pipeline enclosure.
The individual number average that goes out kind of a mouth (18) and discharging tube (8) of distributor (7) is identical with the sowing line number of one-stop operation.Under the prerequisite that the discharge capacity of the blast of sower tractive force, blower fan (3) and air quantity, seeding batcher (1) allows, can satisfy the sowing needs of different operating fabric width by the number that increase distributor (7) goes out kind of a mouth (18) and discharging tube (8).
The parts that the present invention is used, except that distributor (7), injector (4), seeding batcher genus such as (1) designed voluntarily and process, all the other parts were outsourcing standard universal spare.Injector (4), distributor (7) utilize No. 45 steel to adopt mach mode to obtain, and can utilize die casting to become plastics or ironcasting during batch process.Seeding batcher (1) can accurately be regulated the outer groove wheel seeding batcher that can satisfy the amount of broadcasting seeding greatly for the amount of broadcasting.Bend pipe (5) and pressure inlet (6) are respectively standard-sized pvc pipe road and plastic tube.
Seeding unit when work blower fan (3) and injector (7) are installed in the machine of being made by angle steel respectively and add, guarantee to stablize, firmly.
When the present invention works, the seed in the seed-box is broken the whole up into parts, require quantitative seeding and form even seed flow according to the amount of broadcasting by seeding batcher (1).By seed flow and blower fan (3) high velocity air that the provide even mixed flow that converge formation of injection in the mixed chamber (14) of injector (4), enter in the distributor (7) after corrugated pressure inlet (6) supercharging along transporting elbow (5) then, further carry out branch's seeding, finally carry out the concentrated seeding process of unified " the device multirow " carried of air-flow by going out in kind of a mouth (18) the inflow discharging tube (8).
