Description
Technical field
The present invention relates to the technical field of agricultural machinery implanted device.
Background technology
Air-suction seed metering device comprises negative pressure chamber, seed chamber and the large critical piece of sucker three, sucker isolation negative pressure chamber and seed chamber.During work, negative pressure chamber creates air negative pressure under the effect of blower fan, makes the suction hole on sucker produce the air-flow flowing to negative pressure chamber from seed chamber, and air-flow drives the seed in seed chamber to be close to the suction hole of sucker.Along with the rotation of sucker, the seed being attached to suction hole is taken out of seeding unit, after forwarding negative pressure chamber border to, negative pressure is eliminated, and seed is discharged under gravity, realizes the object of sowing.
Current air-suction seed metering device abroad with China northeast, the Northwest's extensive use, be mainly used in seeding corn, soybean, cotton, sunflower etc., but be not suitable for China's Huang, Huaihe River, Haiti district seeding corn.After getting used to getting wheat in summer mainly due to this area's corn seeding, directly sow at field from which wheat has been reaped.The air negative pressure that air-suction seed metering device produces easily sucks the foreign material such as wheat straw or wheat bran, causes seeding unit to block, affects normal operation.
In order to solve the problem of the foreign material such as wheat straw or wheat bran blocking air-suction seed metering device, somebody attempts the height raising seeding unit, but after seeding unit increases, charges seed and highly also increase, bring again the inaccurate problem of spacing in the rows.
Summary of the invention
The subject matter that the present invention solves is to provide a kind of air-suction seed metering device, solves the blockage problem of the foreign material such as wheat straw and wheat bran, can not suck the foreign material such as wheat straw or wheat bran, ensure normal seeding operation.Be specially adapted to China's Huang, Huaihe River, Haiti district seeding corn.
Main technical schemes of the present invention is: a kind of air-suction seed metering device, mainly comprise the rotation suction cup, the seed chamber that negative pressure chamber, side surface circumference are evenly equipped with suction hole, rotation suction cup segmentation negative pressure chamber and seed chamber, be slidably matched between negative pressure chamber and rotation suction cup, it is characterized in that: be provided with inlet plenum, seed chamber adds kind of a mouth and is provided with closing cap, and inlet plenum is positioned at seed chamber side, be provided with UNICOM's mouth between seed chamber and inlet plenum, inlet plenum is in communication with the outside by filter; The bottom of negative pressure chamber is provided with pressure release seeding chamber, at least can drain the seed of a suction hole.
Modified node method is, the below in described pressure release seeding chamber is provided with to deposit to plant leads kind of wheel and a shell thereof, and lead kind of a wheel and rotate in the enclosure, the bottom of described shell is provided with mouth of charging seed; Deposit and kind lead kind of a wheel and be connected by synchronization mechanism transmission mechanism with between rotation suction cup.
Preferably, described synchronization mechanism transmission mechanism is gear pair.
Preferably, described depositing kind is led kind of a structure for wheel and is, deposits kind to lead kind of a peripheral distribution for wheel and have and fill kind of a ditch, fills the position of kind of ditch corresponding when rotating with the position of the suction hole of sucker.
Preferably, when adopting monoseeding, described in deposit kind to lead on kind of wheel to fill the quantity of kind of ditch identical with the quantity of the suction hole on rotation suction cup; Or when adopting many to sow, quantity and the suction hole number ratio of filling kind of ditch are 1:N, for being greater than the natural number of 1.
Described depositing kind is led kind of a structure for wheel and is, described in deposit the common factor filling kind of ditch place circle and the suction hole place circle on sucker of kind to lead on kind of wheel, what pressure release outflow place of the seed in seed suction hole was positioned at correspondence of occuring simultaneously leads the center that kind of wheel fills kind of ditch.
Good effect of the present invention is: compared with the prior art, solves the blockage problem of the foreign material such as wheat straw and wheat bran, can not suck the foreign material such as wheat straw or wheat bran, ensures normal seeding operation, and ensures that spacing in the rows is accurate.Be specially adapted to China's Huang, Huaihe River, Haiti district seeding corn.
During work, seed chamber is isolated from the outside, and air-flow from the supply of newly-increased inlet plenum, because inlet plenum adds filter, can only ensure that the foreign material such as wheat straw or wheat bran do not enter seeding unit.
Strengthen the terrain clearance of seeding unit, increase in the space that seeding unit and ground are increased and deposit kind and lead and kind to take turns.Air-suction seed metering device after increasing, away from the wheat straw on ground and wheat bran, avoids the foreign material such as wheat straw or wheat bran to enter seeding unit further.Seed finally leads kind of a wheel discharge by depositing to plant, and deposits to plant and lead kind of wheel overhead apart from very near, highly can not increase, therefore ensure that spacing in the rows is accurate so seeding unit is charged seed after increasing.
Be described further below in conjunction with accompanying drawing and preferred embodiment, but not as limiting the scope of the present invention.
