Description
Technical field
The present invention relates to technical field of seeders in the agricultural machinery, be specifically related to a kind of centrifugal integrated arranging precise rape seeding device.
Background technology
Rape is the big oil crop of the first in the world, and China's rapeseed cultivation area and gross yield all occupy first place, the world.Yet owing to reasons such as the rape seed particle is little, in light weight, oil content big, crackies, for a long time, the mechanization of rape sowing receives very big restriction always.Seeding unit is the core work parts of sower, and the quality of seeding unit seeding quality is directly connected to the quality of sowing.The rape seeding unit can be divided into two kinds of mechanical type and pneumatic types according to operation principle.The mechanical type seeding unit is simple in structure, cost is low, but usually operating speed is lower and be prone to cause the damaged and type hole plug of rape seed; Pneumatic type seeding unit versatility is good, operating speed is high and injuring-free seed, but structure is complicated, and cost is high.And the seeding unit of traditional mechanical and pneumatic type belongs to " a device single file " pattern more, the general seeding operation of only being responsible for delegation of seeding unit, and sower is bulky, complex structure, deadweight are bigger.For alleviating the complete machine weight of sower, simplified structure improves seeding efficient, realizes high speed, wide cut operation, and the collection row device of development " a device multirow " is a direction of following seeding unit development.Collection row device has had application in big particle diameter seed such as wheat, corn, but also relatively more rare for the collection row device of small particle diameter seed land for growing field crops precision drilling such as rape.Therefore; Centrifugal integrated arranging precise rape seeding device of the present invention is simplified the complete machine structure of sower for improving operating efficiency, improves the mechanization degree of rape; Guarantee that rape seed the most reasonably distributes in the field; Reduce field thinning recruitment, thereby realize the rape high and stable yields, have important realistic price.
Summary of the invention
The object of the present invention is to provide a kind of centrifugal integrated arranging precise rape seeding device, concentrated through a kind case to supply to plant, relied on centrifugal force to realize a device multirow seeding, its amount of broadcasting accurate and adjustable, simple in structure and injuring-free seed.To achieve these goals, the present invention realizes through following technical proposal:
A kind of centrifugal integrated arranging precise rape seeding device; Comprise kind of case 1, cover plate 2, external conical-tube 3, seed output pipe 4, inner conical-tube 5, bracing frame 6, bedplate 7, driving shaft 8, seed outlet 9, clip 10, bearing block 11, clear brush 12 and the seed inlet 13 of planting, said seed inlet 13 is positioned at the bottom of kind of case 1, and external conical-tube 3 bottoms are installed on the bedplate 7 through bracing frame 6; Inner conical-tube 5 top edges are equipped with plants brush 12 clearly; Seed output pipe 4 is fixed on the external conical-tube 3 through clip 10, and 3 have some seed outlets 9 on the described external conical-tube, and driving shaft 8 is installed on the bearing block 11; Bearing block 11 is fastened on the bedplate 7 through bolt, and this bedplate 7 is connected with mainframe through bolt.
Said inner conical-tube 5 is 35-60 ° with the inclination angle of horizontal direction, and inner conical-tube 5 preferably of the present invention is 45 ° with the inclination angle of horizontal direction.
During work, rape seed in the even continuous inflow inner conical-tube of seed inlet, is filled the seed inlet control of kind of speed by kind of lower box part by kind of case, and the aperture of seed inlet is adjustable, makes the grain weight in the inner conical-tube keep constant.Driving shaft drives the inner conical-tube rotation; The inner cone barrel rises to the height by cover plate control to rape seed in the inner conical-tube in the action of centrifugal force lower edge; Seed outlet through being positioned on the under external conical-tube barrel is discharged successively, and clear kind brush is removed unnecessary seed and when taking place to stop up, seed outlet cleared up.Centrifugal feed can be realized the adjusting to seeding quantity through regulating seed inlet aperture and inner conical-tube rotating speed; Can realize the precision drilling of Different Crop seed through the external conical-tube of changing the different seed outlet versions of configuration; Can realize the sowing of different line numbers through configuration varying number seed output pipe; Can realize that through configuration clutch below driving shaft the field is transported, turned around, the time-out of seeding operation when turning.
The invention has the beneficial effects as follows:
1, centrifugal integrated arranging precise rape seeding device of the present invention is simple in structure and can realize a device multi-row seeding, and the sowing line number is adjustable, and has alleviated the wound kind situation of mechanical type seeding unit;
2, the centrifugal integrated arranging precise rape seeding device amount of broadcasting of the present invention is accurate, goes out to plant evenly, and it is adjustable to go out kind of amount, can satisfy the agriculture requirement of different regions rapeseed cultivation.
3, the present invention also can be used for the precision drilling of other crop through suitable adjustment.
