Description
Technical field
The present invention relates to technical field of agricultural mechanical equipment, be specifically related to a kind of adjustable aspiration type seeding machinery.
Background technology
China is peanut production state main in the world and peanut country of consumption, and be also maximum peanut exported country, the cultivated area of its peanut accounts for about 20% of world's gross area simultaneously, occupy second place of the world, gross yield accounts for Century Square 0%, ranks first in the world, and year foreign exchange earning reaches 6.1 hundred million dollars.Sowing is important step in peanut production process, and peanut cultivation machineryization not only can boost productivity, liberation labour, and can improve productivity effect, promotes increasing both production and income.Because air-suction type seed metering device is tight to seed sizes requirement, do not need selected classification, wound is planted few, easily realizes simple grain program request, and sower operating speed raising potentiality are large, obtained research and apply widely.The difference of object and cropping pattern is sowed in seeding process, different requirements is all had to the size of suction hole size, every seed number per and cave distance, the adjustment of existing air-aspiration type peanut hill-drop planter generally adopts the mode changing the seeds sucker and duckbilled assembly with different suction hole quantity and different pore size to complete, because seeds sucker is arranged on hole sowing wheel wheel inside, adjustment cave distance needs the replacing that parts dismounting just can be completed seeds sucker, therefore loads and unloads and reset to bother very much.In addition, current air-aspiration type hole sowing machine can not change the sowing quantity in every cave, and this exists larger difficulty for the user.
Summary of the invention
The utility model is the weak point for avoiding existing for above-mentioned prior art, a kind of adjustable seeder is provided, this device can according to broadcast crop seed profile, the cropping pattern of crop and the requirement of Seeding Quantity, controlled the seed on seeds sucker by the control valve vacuum controlled in air chamber in different circular arc cavity, and then effectively achieve in facility seeding process the large seedlet of different profile, every cave Seeding Quantity and the different conversion sowing caves distance.
The utility model is that technical solution problem adopts following technical scheme:
The design feature of a kind of adjustable seeder of the utility model is:
Air chamber (3) is set and seeds sucker (4) is inserted on the power transmission shaft of sower; Described seeds sucker (4) embeds the right side of described air chamber (3); Described air chamber (3) cavity connects air inlet pipe (2); Described air inlet pipe (2) is arranged on control valve (1).
The design feature of a kind of adjustable seeder of the utility model is also: air chamber (3) top arranges multiple circular arc cavity, and bottom has dead slot.Seeds sucker (4) is upper arranges hole not of the same race, and the size shape in same diameter kind hole is circumferentially identical, and the size shape in the kind hole that different-diameter is circumferentially arranged can be the same or different, and planting the size in hole, shape and spacing according to what sow needs setting.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the seeds sucker structure of the utility model employing, it arranges hole not of the same race, sower transformation to the seed and every cave Seeding Quantity of broadcasting different profile size in seeding process can be realized fast, meanwhile, the transformation of planting with sowing machine cave distance and seed line-spacing can be realized.
2, the utility model adopts air chamber top to arrange the structure of multiple circular arc cavity, this structure controls the vacuum of each cavity in air chamber by control valve, control the seed on seeds sucker on diverse location effectively easily, achieve seeder fast and safely get kind.
3, the utility model overall structure is simply novel, easy and simple to handle, time saving and energy saving; Be applicable to the smart seed-fetching of the large seeds such as peanut, sower transformation to the large seedlet of different profile, every cave Seeding Quantity and sowing cave distance in seeding process can be realized fast, widened the scope of application of seed tray, improve seeding quality, reduce labor intensity, improve sowing efficiency.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of the utility model;
Fig. 2 is the utility model side-looking complete section structural representation;
Fig. 3 is the utility model seeds sucker structural representation;
Number in the figure: 1 control valve, 2 air inlet pipe, 3 air chambers, 4 seeds suckers.
Embodiment
The design feature of a kind of adjustable seeder of the utility model is:
See Fig. 1 and Fig. 2, air chamber 3 is set and seeds sucker 4 is inserted on the power transmission shaft of sower; Described seeds sucker 4 embeds the right side of described air chamber 3; Described air chamber 3 cavity connects air inlet pipe 2; Described air inlet pipe 2 is arranged on control valve 1.
In concrete enforcement, as depicted in figs. 1 and 2, described air chamber 3 top arranges multiple circular arc cavity, and bottom has dead slot.
As shown in Figure 3, seeds sucker 4 is arranged hole not of the same race, the size shape in same diameter kind hole is circumferentially identical, and the size shape in the kind hole that different-diameter is circumferentially arranged can be the same or different, and planting the size in hole, shape and spacing according to what sow needs setting.
Operating process:
Before sowing, according to plantation agronomy and seed size requirement, the seeds sucker 4 chosen, air inlet pipe 2 is connected with the separate circular arc cavity of air chamber 3, then by the seeds sucker 4 chosen be inserted on the turning cylinder of sower with the air chamber 3 of air inlet pipe, finally the other end of air inlet pipe 2 is connected with the control valve be fixed on sower.
During sowing, according to plantation agronomy and seed size requirement, determine suction hole seeds sucker 4 participating in work, determine the working cavity that air chamber is corresponding immediately, by opening the valve of control valve 1 correspondence, by the air inlet pipe of correspondence, pass into gas, now corresponding operation cavity produces negative pressure; Simultaneously, under power transmission shaft drives, seeds sucker 4 rotates relative to air chamber 1, under the logical gas respective chamber of air chamber 3 produces the effect of negative pressure, seed is adsorbed on the suction hole of corresponding seeds sucker 4, and take the seed of absorption out of seed chamber, when forwarding dead slot region, air chamber 3 bottom to, because negative pressure disappears, the seed of absorption falls in seed box corresponding to lower end in the effect of deadweight, realizes getting kind of a process.In addition, Seeding Quantity determines to broadcast several seeds by there being several cavity to produce negative pressure in air chamber, namely has two cavitys to produce negative pressure, so broadcast two seeds in a kind cave simultaneously.This device determines the operation cavity in air chamber 3 by control valve 1, complete the determination to seeds sucker 4 participating in operation suction hole, and then achieves the adjustment to Seeding Quantity and cave distance in the plantation of different plant species and seeding process.
