Description

Seedlet precision seeding machine in roller

Technical field

The present invention relates to hand propelling rolling-type seeding machine, specifically provides seedlet precision seeding machine in a kind of roller.

Background technology

The plant seed of small particles, due to its small volume light weight, enters in the hand-push type seeder using traditional structure Row applies sowing time, takes kind of wheel and is often scanned out or be stuck in hairbrush by hairbrush along the middle seedlet Jing in hole is planted weeks, leakage seed easily occurs existing As, cause broadcast leakage, in causing the underproduction, also, the hand-push type seeder of drive mechanism, moving component is more, and the electrostatic that body is produced is inhaled Phenomenon is more obvious, can adsorb seedlet on structural member, with the reciprocating motion of component, seedlet be squeezed wound easily, Underground is sown into defective seed to be difficult to emerge, the underproduction can be caused, so during machine sowing, in order to ensure emergence rate, generally making With in, multi-form agriculture mechanical planting, with the bar hole that the traveling of machinery is marked in advance on the platform of ridge carry out it is continuous it is continual sow seeds, Can guarantee that seed is complete, emergence rate is high, has the disadvantage, after planting adjacent seedling spacing is closeer and uneven for the method, the later stage needs Extractd at a distance of excessively near or unnecessary Seedling, will also be filled the gaps with seedlings at a distance of between Seedling too far, not only wasted seed and soil nutrient, also increase Add manpower and man-hour, and when the seed of light weight is broadcast, during seeds fall, easily affected by nature wind, Appearance is broadcast partially, causes seed level inadequate or naked broadcasts；In the location that the inconvenience of the big machineries such as patch, remote land on slope launches, also adopt mostly Sow by hand, have the disadvantage that working strength is big, it is low to sow efficiency.

The content of the invention

The purpose of the present invention is：Seedlet precision seeding machine in a kind of roller is provided, the short grained plant seed of energy centering enters Row machine sowing, the accuracy rate height of machine sowing, quality are good, spacing is uniform, can save seed, save manpower, time, it is ensured that emergence rate.

The technical scheme is that：Seedlet precision seeding machine in roller, including push rod, plants case, and push rod front end is equipped with master Axle, plants case and is connected on push rod by axis rotation of main shaft, it is characterised in that：Plant, Each device of sowing includes arc, plants storehouse, inoculating groove and duckbilled, and arc is flexibly connected with case is planted, the intrados of arc Upper to take kind of a spoon and be flexibly connected with arc equipped with kind of a spoon is taken, arc is provided with through hole, positioned at the through hole one of arc extrados End is connected with inside duckbilled, and the stator in duckbilled is connected with arc, and the other end of through hole is connected with the seed outlet for planting storehouse one end, The side for planting the storehouse other end is provided with seed inlet, and seed inlet is connected with inoculating groove one end, and the notch of inoculating groove is relative with kind of spoon is taken, and connects The notch of kind of groove and take and kind between spoon and arc, be provided with gap.

Be fixed with support on described push rod, runner be housed on support, runner successively with positioned at kind of upper box part when it is each under Plant the driving lever activity crimping of duckbilled in device.

The guide block of two arrangements that are in the shape of the letter V is fixed with the intrados of arc, and the wealthy mouth end of two guide block one end is located at plants The both sides in storehouse, are provided with gap between the wealthy mouth end and kind storehouse, the slot end of two guide block one end is located at the both sides for taking kind of spoon, the slot Holding and taking gap is provided between kind of spoon.

Described kind case is fixed with adjuvant storehouse, is provided with charge door at the top of adjuvant storehouse, is stamped lid, adjuvant storehouse on charge door Bottom be provided with discharging opening, discharging opening connect inside case with planting, and equipped with normally closed type door on discharging opening, adjuvant storehouse is built with graphite Powder or Pulvis Talci.

The present invention operation principle be：So that one of them sows device as an example, plant in case and be pre-loaded with a certain amount of seed, Seed is gathered in the bottom of kind of case under gravity, and when kind of case is rotated, seed is stirred and stirred out, when the device position of sowing When kind of bottom portion, in the seed of disturbance, seed taking in kind of spoon into the device of sowing corresponding with kind of spoon is taken, is taken kind of a spoon Taking-up is taken away, and when this takes kind of spoon turns to top with kind of a case, takes the spoon mouth of kind of spoon downwards, seed due to from gravity fall with take Plant in the relative inoculating groove of spoon, as kind of a case is rotated further, seed is slipped in kind of storehouse from inoculating groove, when device rotation of sowing When bottom portion is planted, seed is fallen in duckbilled by seed outlet, and duckbilled completes sowing by linkage structure folding.

It is an advantage of the invention that：The short grained plant seed of energy centering carries out machine sowing, and with the kind bale-out kind of constant volume, which takes kind Complete in body to sowing, do not disturbed by external environment condition, the accuracy rate that can make machine sowing is high, quality is good, can save seed, due to It is rolling type sowing implement, when device of respectively sowing uniformly is arranged on the circumference of kind of case, can makes to apply the spacing broadcast uniformly, due to taking Seed, seeding down accuracy are high, save except Seedling operation, can save manpower and time, can ensure that emergence rate and yield again.Activity is even What is connect takes kind of spoon and can be changed according to the size of different seeds, makes the seeder of the present invention adapt to the middle microspecies of various sizes Son, raising take the accuracy rate of seed, seeding down.

Described runner can promote positioned at kind of upper box part sow device in duckbilled driving lever, open the moving plate in duckbilled, When driving lever is separated with runner, moving plate rapid return in the presence of torsion spring taps the microseism that stator is produced by moving plate, makes to take Plant spoon and vibrations also occur, surface villous or seed by electrostatic adsorption can be made smoothly to depart from and take kind of a spoon, the standard sowed can be improved True rate.

Described V-shaped arrangement guide block, can guide seed in kind case gather at kind of spoon to take, the seed residue in kind of the case In the case that amount is less, also ensure that taking kind of spoon can get seed every time, can improve and take the success rate planted.

Graphite powder or Pulvis Talci in adjuvant storehouse is added in kind of case by a certain percentage, when kind of case is rotated, graphite powder And Pulvis Talci can play a part of to lubricate between seed, it is to avoid seed is because of electrostatic, humidity is inter-adhesive or sticks in each of seeder On structural member, keep seed loose, meanwhile, after the surface of the seed wraps up one layer of graphite powder or Pulvis Talci, can increase makes the surface of the seed Smoothness can increase the deadweight of seed again, smoothly drop in inoculating groove from taking in kind of spoon beneficial to seed, finally slide to duckbilled It is interior；Described graphite powder and Pulvis Talci are natural solid lubricant, and powder more than preferably thousand mesh, due to seed very little, institute The powder amount of adhesive tape is little, and seed or environment will not be impacted.
