Abstract
A kind of electronic pulsed precision feed mechnism, it is made up of machine driving and electronic impulse control circuit two parts, and trigger on the mechanical trigger circuit and sower land wheel commissure produce and the synchronous electric impulse signal of sower, handle through frequency changer circuit, by switch HK
1Select, reciprocating plate rectilinear motion on the seeding body that A, two helix tube type electromagnet of B alternation drive lever connect, change the seeding unit electrical impulse frequency and change the sowing spacing in the rows and the amount of broadcasting, these facility have novel structure, volume little, easy to install, sowing precision height, characteristics such as cost is low.Can be widely used in the precise sowing of crops such as farmland soybean, corn, be the ideal equipment of present farmland sowing.
Description
The present invention relates to the farmland seeding apparatus, agriculture more precisely field seeding soybean and corn electronic pulsed precision feed mechnism.
At present, agriculture field seeding soybean, corn generally all adopt manual sowing and mechanical planting, and when planting seed, simple grain rate, seed-filling rate and percentage of damage are very undesirable, and the loss and waste seed is comparatively serious, and the precision of spacing in the rows is also lower.Higher according to utility model patent 88214705.6 complete machine costs, the external difficulty of power supply, and be only limited to the sowing of granule such as extensive wheat, the amount of broadcasting adjustment is by quantitatively door machinery adjustment, do not have surveillance, be easy to occur sky and broadcast when breaking down, loss and waste seed or disconnected bar influence the strain number of keeping a full stand of seedings.
The objective of the invention is to have designed a kind of electronic pulsed precision feed mechnism, be mainly used in precise spot-sowing soybean and corn, can realize wall scroll or double-row drilling on the ridge in order to overcome the defective of above-mentioned existence.Seeding unit is controlled by electronic impulse, and the levelling electrical impulse frequency can reach the required spacing in the rows and the amount of broadcasting, and be furnished with light-emitting diode assembly, can see the working condition of looking into seeding unit at any time.
Operation principle of the present invention and structural relation: with the trigger of sower land wheel commissure, produce and the synchronous pulse signal of sower, handle through frequency changer circuit, by switch HK, select, drive lever via A, the alternating movement of two helix tube type electromagnet of B and connect the dropping frequency that reciprocating plate rectilinear motion on the seeding unit changes seeding unit, synchronous because of pulse signal and sower, therefore can change the spacing in the rows and the amount of broadcasting sowed.
The working method of seeding unit adopts linear reciprocating.Seed charges into and launches except that by the seed deadweight the kind hole of seeding reciprocating plate, implements mandatoryly to charge into and launch.
Charging into of seed in the seeding unit work, launching its speed is to be determined by the electrical characteristic of electromagnet, and does not change because of the seeding unit dropping frequency.
The work of seeding unit is controlled by electrical pulse circuit, is not subjected to the restriction of mechanical transmission structure.Installation site and mode are more random.
The seeding body is the core key part of whole seeding unit.Because clear kind dividing plate is fixed on the centre position of seeding body, makes the seeding body form A and two kind chambeies of B.If electromagnet A has signal, when reciprocating plate was moved to A kind chamber, owing to plant ratio back, forward position, hole along low, (by the traffic direction of reciprocating plate) made the volume in kind of chamber diminish like this, utilize the reaction force and the kind forward position, hole of planting the chamber seed this moment low, the back charges in the B kind hole seed along the deadweight of height and seed by force; Meanwhile, the seed in generation is taken when planting dividing plate clearly in A kind hole, and unnecessary seed is eliminated and only surplus seed; Because this moment, A kind hole was the forward position height, the back is the rigid structure form along low (by the reciprocating plate traffic direction) though plant dividing plate clearly, can not injure seed for this reason.When the reciprocating plate stroke stopped, just A kind hole arrived and charges seed a little, by force seed is released from A kind hole under the effect that pushes away kind of sheet; Otherwise when electromagnet B had signal, said process carried out on the contrary.Because pulse signal is constantly alternately imported the above-mentioned motion of electromagnet A or B and will be gone on again and again.
Economic and social benefits of the present invention are better.This machine has improved operating efficiency again, dropping frequency 13/S owing to adopt electronic impulse control both to reduce mechanical breakdown; Seed-filling rate reaches more than 99.9%; The simple grain rate reaches more than 99.9%; Percentage of damage is no more than 0.20%.
