Description
Technical field
The present invention relates to a kind of moving drum-type seeding unit of cam of determining, be especially applicable to the agricultural machinery research field of precision drilling.
Background technology
At present, known seeding unit form mainly contains mechanical type and air-sucking type seeding mode, and other pattern also has magnetic-type and oscillatory type etc.Common form mainly contains following several: mechanical board-like sower is the most simple a kind of type of seeding, adopts the manufacture of dislocation principle.The work production efficiency of this seeding mode is higher, be approximately the more than 50 times of artificial seeding, but exist seeding accuracy low, and easily wound is planted, and exist resowing phenomenon, so just to sowing, has brought adverse influence.The board-like sower of aspiration is to utilize the absorption affinity of air-flow or press attached power; seed is adsorbed from kind of heap; realize simple grain or two s' precision drilling, to seed category strong adaptability, injuring-free seed; can high speed operation; be to use at present maximum seeding methods, but this sowing rely on seed to fall under gravity in Pan Xue hole, cave, completes seeding process one time; this seeding method cannot guarantee that whether seed can very fall down, and cannot guarantee planting rates.Drum-type sower inside is a totally enclosed negative pressure of vacuum chamber, and cylinder surface accurately offers sucker, and hole sucting diameter is definite according to seed size, and sucker is corresponding with Pan Xue hole, cave, and communicates with vacuum chamber.This seeder can meet many-sided requirement, and adaptability is good, but cost is too high, for agricultural machinery, does not calculate.
Above-mentioned said seeding unit has following deficiency and shortcoming: seed is easily formed to damage, affect emergence rate; Cannot guarantee spacing, seeding accuracy is low, and thick rare inequality appears in the growth that causes growing seedlings, and affects output; In seeding process, may there is resowing phenomenon, affect equally crop yield; Cannot guarantee that crop seed drops in Pan Xue hole, cave in place, cannot guarantee planting rates; Cost is too high, is not suitable for agricultural machinery application etc.
Summary of the invention
In order to overcome all deficiencies and the defect existing in prior art, the object of the present invention is to provide a kind of moving drum-type seeding unit of cam of determining, it not only can meet above-mentioned requirement, and can coordinate other mechanisms jointly to regulate the efficiency of sowing when crop is sowed.
The technical solution adopted for the present invention to solve the technical problems is a kind of moving drum-type seeding unit of cam of determining, comprise frame, protect kind of an adjusting rod, push rod shaft, cylinder, storage device, camshaft release handle, protect kind of a device, back-moving spring, side plate, gear, camshaft, it is characterized in that: described camshaft is installed and is fixed in frame by camshaft release handle, described side plate has two of left and right, by bearing, be installed to camshaft two ends, described push rod shaft arrives in the chute of side plate by spring fitting, described cylinder couples together by screw and side plate, and push rod must be in cylinder nest in the eyes, described kind of the adjusting rod that protects is installed in frame, describedly protect kind of device and protect kind of an adjusting rod and be connected to together, described storage device is installed in frame, and be tightly attached on the outer surface of cylinder, on the side plate of on the left side, gear is installed.
Described above-mentioned seed dropping mechanism can transverse shifting in the frame of sower, and stopping means has been installed on seeder frame.
A kind of operation principle of determining the moving drum-type seeding unit of cam of the present invention is:
Camshaft maintains static, when power is delivered on cylinder by being arranged on gear wheel on cylinder, cylinder rotates immediately, cylinder drives push rod shaft to rotate when rotating, push rod shaft contacts with cam by rolling bearing, when push rod shaft is along with cylinder revolution, push rod shaft is also being done lengthwise movement by cam profile curve, when the bearing movable in push rod shaft arrives cam greatest circle position, push rod seed from cylinder nest in the eyes face push out, therefore, as long as guarantee that seed can be stored in nest and just can guarantee that seed is seeded in ground completely in the eyes, when cylinder slowly rotates, firm radially the rebounding towards cam along cam profile curve slowly of the push rod in cam greatest circle position under the effect of back-moving spring, realize stored seed and released the such cyclic process of seed.Described above is the operative scenario of row's push rod shaft, the operation principle of all the other 4 row's push rod shaft and above-mentioned just the same.
The invention has the beneficial effects as follows, can in sower work, realize continuous plantation, productivity ratio is high, and can be by regulating the output speed of electromotor to regulate operating efficiency; Seed can be not damaged at seeding time; In planting process, longitudinally the spacing of seed guarantees by gearratio, can meet high-precision requirement; Originally novel use is electronic mode, can save labour, reduces costs; And used a speed changer, when advancing, realized sowing, when retreating, also can realize sowing.
