Description
Technical field
The present invention relates to one kind can disposably complete a kind of air-blowing to the accurate seeding operation of corn for the drum-type of kind
Feed mechanism for seed.
Background technique
Corn originates in Latin America, is annual gramineae herbaceous plant.2.19 hundred million tons of China's corn total output in 2016,
About 5,000,000 tons were reduced than 2015,3675.9 ten thousand hectares of corn seeding area, declined 3.11% than last year；5.97 tons of per unit area yield/public affairs
Hectare, increase by 1.36% than last year, feeding demands in 2016 and industrial requirement are increased.It is deposited by live pig livestock on hand and the numerous sow of energy
Column increases and the factors such as the substitutes import volumes such as sorghum, barley, import corn distiller's dried grain (DDGS) decline influence, it is contemplated that
Corn feed consumption in 2015/16 year is 1.02 hundred million tons, increases by 2,000,000 tons than last year；Corn industry consumption will increase than prior year
4080000 tons, reach 54,500,000 tons；Currently, China is to the most of machines using spline and indent type seed wheel of the plantation of corn
Tool broadcasts sowing.
But the slot or Kong Jun in such device be there are a degree of wound kind, broadcast leakage, replay, plug-hole and is unable to control kind
The problems such as sub- spacing cause corn seedling survival rate low at seeding time, this virtually increases the production cost of enterprise,
And efficiency is very low, is not suitable for planting on a large scale, various drawbacks seriously constrain the sustainable development of Maize Industry.
Summary of the invention
Existing wound kind when in order to overcome spline and indent type seed wheel maize planting, broadcast leakage, replay, plug-hole and can not
Control seed spacing and the problems such as inefficiency, the present invention provides a kind of air-blowing for the drum-type feed mechanism for seed of kind.
The technical solution adopted by the present invention to solve the technical problems is:
The air-blowing includes motor for the drum-type feed mechanism for seed of kind, and conveyer belt, plants case, for kind of a plate, seed inhales kind of a roller, roller machine
Frame, hole tray, rack, motor, negative pressure air supply pipe, positive pressure ventilation pipe, vortex pump, it is characterised in that: when work, motor passes through chain
It is driven driving conveying belt rotation and roller rotation；The negative pressure air supply pipe of vortex pump and the negative pressure axis connection of support roller, positive pressure
Air supply pipe is connect with for the plemum below kind of plate；Negative pressure air supply pipe leads to negative pressure in drum cavity, and cylinder surface sucker is the same as negative
Pressure communicates, and positive pressure ventilation pipe leads to positive pressure in plemum, beats in plants case for the seed on kind of plate at this time；With turning for roller
It is dynamic, when suction hole passes through for kind of device, it is attracted on suction hole under the action of seed Negative Pressure Difference, is rotated with roller；Work as process
When rotary broom, extra seed is cleaned back plants case；When the seed on the same bus of roller goes to corresponding hole tray immediately below roller
When hole site, with the decrease of negative pressure, in the cavities that seed falls into seed plate under the action of air-flow and self gravity, complete to charge seed
Process.
Include positive pressure collection chamber for planting hardened structure, leads kind of a plate, it is characterised in that: for kind of plate by leading kind of plate and positive pressure collection chamber
Composition, and roller is angled is mounted on the lower section of plants case (greater than the sliding friction angle of small granule seed), close to roller
One end be provided with and lead kind of a plate, two lead the aperture blowing of regular arrangement between kind of plate, a diameter of 1.5mm, positive pressure collection chamber and supply
Kind plate bonds together, and in the lower section for leading kind of plate, effect is to guarantee that " boiling can be generated under airflow function for the seed on kind of plate
Rise ", it is similar to suspended state.
The invention has the advantages that the Precise sowing to corn is disposably completed in the air-blowing for the drum-type feed mechanism for seed of kind
Equal operations, with high production efficiency, mechanization degree is high, labor intensity of operating staff is small, equipment life is long, compact-sized, system
The features such as making easy, stable and reliable in work, reduction production cost, conveniently moving and application easy to spread.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is general structure schematic diagram of the invention.
Fig. 2 is for kind of a plate structural schematic diagram.
1. motor in Fig. 1,2. conveyer belts, 3. plants cases, 4. for kind of a plate, 5. seeds, and 6. inhale kind of a rollers, 7. roller racks, and 8.
Hole tray, 9. racks, 10. motors, 11. negative pressure air supply pipes, 12. positive pressure ventilation pipes, 13. vortex pumps.
14. positive pressure collection chamber in Fig. 2,15. lead kind of a plate.
Specific embodiment
In Fig. 1, including motor, conveyer belt, plants case, for kind of a plate, seed is inhaled and plants a roller, roller rack, hole tray, rack,
Motor, negative pressure air supply pipe, positive pressure ventilation pipe, vortex pump, wherein frequency converter adjusts motor (1) and passes through chain conveyer band when working
Dynamic conveyer belt (2) rotation and suction kind roller (6) rotate clockwise, and operate it under synchronized state；Vortex pump (13) is born
It presses air supply pipe (11) and supports the negative pressure axis connection of roller, positive pressure ventilation pipe (12) is connect with for the plemum below kind of plate；It is negative
Air supply pipe is pressed to lead to negative pressure in drum cavity, cylinder surface sucker is communicated with negative pressure, and positive pressure ventilation pipe leads to positive pressure in plemum,
For the seed on kind of plate, " boiling " beats under the action of positive pressure in plants case (3) at this time；With the rotation of roller, when suction hole passes through
When crossing for kind of device, seed is attracted on suction hole under the action of the Negative Pressure Difference of suction hole two sides, and is rotated together with roller；
With continuing to rotate for roller, when by rotary broom, Seed cleaning up extra at suction hole is returned plants case；As the same mother of roller
When seed on line goes to corresponding hole tray hole site immediately below roller, with the decrease of negative pressure, seed is in air-flow and self gravity
Under the action of fall into the cavities of seed plate, completion is charged seed process；Air-blowing can for the whole work process of the drum-type feed mechanism for seed of kind
Be divided into take kind, clear kind, shield kind, charge seed 4 stages.
In Fig. 2, including positive pressure collection chamber, kind of a plate is led, wherein being formed for kind of plate by leading kind of plate and positive pressure collection chamber, with rolling
Cylinder is angled to be mounted on the lower section of plants case (greater than the sliding friction angle of small granule seed), sets in one end close to roller
It is equipped with and leads kind of a plate, two lead the aperture blowing of regular arrangement between kind of plate, a diameter of 1.5mm, and positive pressure collection chamber is Nian Jie with for kind of plate
Together, in the lower section for leading kind of a plate (15), effect is to guarantee that " boiling " can be generated under airflow function for the seed on kind of plate,
It is similar to suspended state, when work, seed is gathered in rolling under the action of inclination installation is on kind of plate by leading kind of plate and gravity
Near 8 suckers of cylinder, when positive pressure collection chamber (14) is connected with air-flow, tomato seeds " boiling " in seed guiding groove are subsequent rolling
Cylinder sucker takes kind to prepare.
