Description
Technical field
The utility model relates to the board-like seeding unit of a kind of double cam, and especially the precision drilling operation of granule seed, belong to the agricultural machinery research field.
Background technology
At present, known seeding unit form mainly contains mechanical type and two kinds of seeding modes of air-sucking type, below the several frequently seen seeding unit form of article:
The board-like seeding unit of machinery is fairly simple a kind of seed feeding method, adopts the manufacture of upper and lower plates dislocation principle.When on upper and lower plates, the nest eye movement is to coincidence, seed can drop to discharging tube by lower plate.This seeding mode work production efficiency is higher, but exists sowing to leak kind of a situation, and fill kind and the planting time shorter, so just to sowing, brought adverse influence.
Air-suction seeding unit is the absorption affinity of utilizing air-flow, and seed is adsorbed onto on seeds sucker, after seeds sucker turns to certain position, stops suction, and seed falls under gravity into discharging tube, realizes precision drilling.This seeding mode is to the seed category strong adaptability, injuring-free seed, can the high speed operation, to use at present maximum seeding methods, but this sowing relies on seed to fall under gravity in Pan Xue hole, cave, complete seeding process one time, there will be in the seeding process and leak kind of a situation, can't guarantee planting rates.
Above-mentioned said seeding unit has following deficiency and shortcoming: mechanical board-like seeding unit seed-filling rate is lower, and the air-suction seeding unit expense is higher, and the board-like and air-suction seeding unit broadcast leakage of machinery is serious etc.
Summary of the invention
In order to overcome the deficiencies in the prior art and defect, the purpose of this utility model is to provide a kind of double cam board-like seeding unit.It not only can meet above-mentioned requirement, and this machinery is less to the seeding space requirement, and expense is cheap.
It is the board-like seeding unit of a kind of double cam that the utility model solves the technical scheme that its technical problem adopts, and comprises return spring 1, plants cam 2, power transmission shaft 3, driving gear 4, driven gear 5, kinds of bank deposits cam 6, ball 7, connecting rod 8, back-moving spring 9 clearly, determines plate 10, moving plate 11 down, above determines plate 12, push rod shaft 13.Described power transmission shaft 3 is installed on frame by bearing, described driven gear 5 is connected by key with power transmission shaft 3, described driving gear 4 and driven gear 5 are meshed, describedly determine plate 10 and above determine plate 12 and be fixed on frame down, described moving plate 11 is arranged on to be determined plate 12 and determines between plate 10 down, and is connected with connecting rod 8;
It is characterized in that: described clear kind of cam 2 directly is connected with power transmission shaft 3 and plants clearly cam 2 working curved surfaces in vertical direction, and described kinds of bank deposits cam 6 is connected with power transmission shaft 3 indirectly by driven gear 5, and kinds of bank deposits cam 6 working faces are in horizontal direction;
Described kind of bar 13 two ends that push away are installed in the chute that frame forms, and and the clear cam 2 of planting contact;
Described connecting rod 8 is used for connecting ball 7 and moving plate 11;
Described return spring 1 makes push rod shaft 13 contact all the time with the clear cam 2 of planting, and described back-moving spring 9 makes ball 7 contact with kinds of bank deposits cam 6 all the time.
The board-like seeding unit operation principle of a kind of double cam of the utility model is:
When transmission of power arrives driving gear, under the driving gear effect, driven gear rotates immediately, due to driven gear and power transmission shaft, to plant cam, kinds of bank deposits cam clearly be to do as a wholely, therefore, inverted cam drives clearly plants cam and the kinds of bank deposits cam also rotates.Because ball contacts with the kinds of bank deposits cam all the time under the effect of back-moving spring, therefore, along with the rotation ball of kinds of bank deposits cam and connecting rod and moving plate move axially along power transmission shaft, when ball moving cehla eye of seeding unit and above determine cehla eye centering and filled kind during in kinds of bank deposits cam extreme lower position, simultaneously half jin of clear kind cam smallest circle with push away kind of a bar and contact; When ball contacts with kinds of bank deposits cam extreme higher position, the moving cehla eye of seeding unit and determine cehla eye centering down, clear plant cam greatest circle diameter place and push away kind of a bar and contact, push away kind of a bar and plant clearly, wherein the effect of return spring and back-moving spring is to guarantee to push away kind of bar to contact with the kinds of bank deposits cam with clear kind cam and ball.
The beneficial effects of the utility model are, this seeding unit can be good at realizing the seeding operation, and it fills kind of the time and the clear kind time is effectively guaranteed.
The accompanying drawing explanation
Fig. 1 is the board-like seeding unit general illustration of a kind of double cam of the utility model.
