Abstract
The utility model relates to an adjustable internal-filling precision seed discharging device, which belongs to a precision seed discharging device for intertilled crops. The adjustable internal-filling precision seed discharging device is composed of a seed discharging device shell, a seed protective cover board, a seed discharging disc, an adjustable seed discharging ring, a seed discharging shaft and a roller-type seed throwing device. The seed discharging disc and the adjustable seed discharging ring are provided with trench holes, and relative position of the trench holes can be changed to seed seeds, such as peanuts, corns, soy beans, etc., with different sizes. The utility model has low seed throwing point, fast seed throwing speed and homogeneous seeding, and does not damage the seeds. The utility model can be matched with a precision seeding machine by single-row manpower, double-row animal power and multi-row mechanical power.
Description
The utility model belongs to the intertillage crop precision seeder.
At present, the program request seeding unit mainly contains mechanical type and pneumatic type two classes both at home and abroad.Mechanical type mainly contains that horizontal circle disc type, nest eye are wheeled, level is transferred outer groove wheel, vertical hole roller, inclination bucket wheel formula, finger-clipped; Pneumatic type mainly contains that air-blowing nest eye is wheeled, the vertical hole roller of air-blowing, the vertical disc type of aspiration.Most ofly can broadcast crops such as corn, soybean, beet, Chinese sorghum, cottonseed and can not broadcast peanut, the seed bad adaptability different to size, the employing that has is changed different seed plates and is broadcast Different Crop.The pneumatic type seeding unit is complicated at present, is difficult for adopting on people's animal power sower.The mechanical type seeding unit when clear the kind, causes mechanical damage to seeds such as peanuts easily, when filling kind, the type hole dimension of being subjected to influences, and when the simple grain Precision Seeding, linear velocity is generally less than 0.36 meter per second, raising speed, easily cause the hole, some sower is charged seed a little higher, and the speed of charging seed is lower, the uniformity of influence sowing cave distance, during many bunch plantings, seed excessively disperses, and cavitation is poor.
For fear of above-mentioned shortcoming, it is a kind of simple in structure that the purpose of this utility model is to provide, and do not change the seed that seed plate just can be sowed different sizes such as peanut, corn, soybean, and it is a little low to charge seed, the speed of charging seed is very fast, have no mechanical damage adjustable in fill precision sower.
In order to achieve the above object, technical characterictic of the present utility model is as follows.
Fill precise seeder in adjustable, by seeder unit shell, protect kind of a cover plate, seed plate, adjustable seeding circle, feed shaft and rolling wheel type seeds depositing apparatus are formed, feed shaft is equipped with at the seeder unit shell center, housing one end face is installed and is protected kind of a cover plate, and lower housing portion is provided with the mouth of charging seed, the seed plate of fixed band slotted eye on the feed shaft, adjustable seeding circle is fixed by bolts on the seed plate, adjustable seeding circle is provided with adjusts the hole, and the rolling wheel type seeds depositing apparatus is installed in the housing mouthful top of charging seed, and charges seed mouthful directly to be communicated with seed-furrow opener.
The rolling wheel type seeds depositing apparatus is made up of stage clip, lever and roller, and lever is fixed on the seeder unit shell, and an end is equipped with roller, and the other end is equipped with stage clip.
Below in conjunction with accompanying drawing the course of work of the present utility model is further described.
Fill the precise seeder generalized section in Fig. 1 is adjustable;
Fill the precise seeder side schematic view in Fig. 2 is adjustable;
Among the figure: 1 seeder unit shell, 2 protect kind of cover plate 3 seed plates 4 adjustable seeding circle 5 feed shafts 6 rolling wheel type seeds depositing apparatus
The utility model is when work, earlier required size is adjusted in the hole on the adjustable row Artenkreis and the slotted eye on the discharge plate, during work, feed shaft drives discharge plate and the rotation of adjustable row Artenkreis, after seed enters the feed mechanism for seed inner chamber by feeding mouth, enter immediately the discharge plate slotted eye, finish and fill kind, it is lower by free gravity row when unnecessary seed rotates to top with discharge plate in the inner chamber, seed in the discharge plate slotted eye enters seeds protecting plate thereupon, discharged through the roller type seeds depositing apparatus by the mouth of charging seed at last, finish the seeding process.
Advantage of the present utility model: simple in structure, can sow the seed of peanut, corn, soybean different size, the seed damage ratio is low, and seeding uniformity is good, can with the general precision planter of single file manpower, the general precision planter of duplicate rows animal power, the general precision planter of multirow machine power supports the use.
Embodiment:
The seed plate internal diameter is φ 180～250mm;
Seed plate and adjustable seeding circle are provided with 4～20 slotted eyes;
Long 20～the 50mm of slotted eye size, wide 10～20mm;
Dark 12～the 14mm of seed plate slotted eye.
Characteristics of the present utility model:
1, owing to fill compound hole in adopting, macropore fills kind, and aperture is quantitative, and discharge plate active line speed can be brought up to 0.72 meter per second by 0.36 meter per second. Discharge plate active line speed is carried Double, can allow seeder under fair speed, to work, do not produce the hole, when sowing the cave apart from 20cm, allow operating rate can reach more than 8 kilometers/hour.
2, because in the work, unnecessary seed is planted by deadweight is clear in the type hole, does not have brusher kind device, cleaning process is few to the seed damage, can broadcast the vernalization seed, plants in damage ratio less than 2%.
3, because the mouth of charging seed is low, and the speed of charging seed is fast, the roller type seeds depositing apparatus is installed, seeding uniformity is good, and the qualified cave of general international standard is apart from be ± the theoretical cave of 1/2L distance, and this feed mechanism for seed can be in ± 1/4L theory cave in scope, qualification rate 〉=more than 90%, improve the sowing uniformity. Many seed cavitation also are better than other feed mechanism for seeds. Cave length≤6cm, the long qualification rate in cave 〉=more than 90%.
4, adopt an adjustable type hole discharge plate, need not change discharge plate, can broadcast peanut, cotton, corn, Soybean and Other Crops, and improved the adaptability to the kind sowing that varies in size. Seed can be strictly not selected, rate of single seed 〉=90%, and 2 ± 1 qualification rate 〉=90% of bunch planting are broadcast the application rate that cottonseed can save kind of 1/3-1/2.
This seeding unit can be used for single file manpower, duplicate rows animal power, the general precision sower of multirow machine power.
