Description
One, technical field: the invention belongs to agricultural mechanical field, relate to the tobacco seeding machinery, particularly the board-like tobacco seeding unit of a kind of slip.
Two, background technology:
The tobacco seeding belongs to the program request form, is a kind of precision metering device mode.The principle that this seeding unit adopts is divided two classes basically, and a class is the mechanical type seeding unit, namely according to the seed grain type, with the type hole seed is separated from kind of case and proper alignment, sows then; Another kind of is air-suction seeding unit, namely with strength seed is separated from kind of case, by grain absorption and be arranged on the seeding unit, sows then.Common form mainly contains following several at present:
(1) air-suction seeding unit, air-suction seeding unit are the absorption affinities of utilizing the air vacuum degree to produce, and seed is adsorbed on the seed plate from kind of case, realize simple grain or many precision drilling.The air-suction seeding unit trafficability characteristic is good, and is not tight to seed sizes and shape need; But air-tightness requires high, and the structure of seeding unit is more complicated also, and wearing and tearing easily.
(2) disc type seeding unit, disc type seeding unit critical piece are to be positioned at kind of the horizontal seeding disk of case bottom, and during the disk revolution, discharge the seed that charges in the type hole in the type hole that the peripheral with good grounds seed grain type of disk is made.Disc type seeding unit mechanism is simple, reliable operation; But the bad adaptability of this seeding unit to sowing at a high speed, strict to seed sizes, versatility is poor.
(3) nest eye Type Seed Metering Device, the workpiece of nest eye Type Seed Metering Device are to be positioned at kind of a case bottom, around the nest eye wheel of horizontal rotational shaft, and the circular nest eye that the with good grounds seed size of nest eye wheel outer rim is made, when nest eye wheel rotated, seed was discharged by gravity.Nest eye Type Seed Metering Device is simple in structure, but to make various nest eyes wheels standby in order to adapt to the different seed demand of particle diameter, increased manufacturing cost.
All there is certain shortcoming in above-mentioned seeding mode, can not satisfy the actual needs of tobacco sowing, must design the tobacco seeding unit that satisfies function and required precision for this reason, realizes accurate seeding, for this reason the design of seeding unit must consider following some:
(1) each parts of seeding unit are answered driven in synchronism;
(2) seed-filling rate of assurance seeding unit;
