Description

Small-sized seed hill-drop feed run

Technical field

The utility model belongs to seeding machinery technical field, specifically a kind of small-sized seed hill-drop feed run.

Background technology

Along with the adjustment of agricultural structure, small coarse cereals mechanization production technology has been mentioned agenda, and in the mechanization production of the crops such as millet, broom corn millet, clover, vegetables, the sowing of defective ejaculation amount is a key technology.The sowing of defective ejaculation amount can be saved seed, makes its reasonable layout in soil, is beneficial to strong sprout, reduces thinning, final singling recruitment, reduces fertilizer and optical energy loss, increasing both production and income, remarkable in economical benefits.At present, precision planter for intertillage crop such as corn, soybean, wheats has been gradually improved and has been widely used, and for fine grain crops such as millet, clover and herbages, because seed particle size is little, good fluidity, realize defective ejaculation amount sowing difficulty larger.In actual production, fine grain sowing use is strip sowing seed discharge device mostly, and its shortcoming is that the amount of broadcasting is large, waste seed, although used the way such as sand and blighted grain of mixing, due to quality, density variation, effect is poor.

Seeding unit is the critical component on sower, and its performance quality plays decisive action to the raising of sower operation quality and efficiency.Precision seeder can be divided into mechanical type and pneumatic type by its operation principle.Pneumatic seeding apparatus comprises three kinds of air-sucking types, air-sweeping type, vapour-pressure type; Mechanical type mainly contains that nest eye is wheeled, disc type, finger-clipped etc.Pneumatic seeding apparatus tool is educated seed strong adaptability, is damaged the advantages such as light, but its complex structure, cost and technical requirement are high.And mechanical seed sowing device is simple in structure, but also exist, seed sizes is required strictly, cannot adapt to the problem such as high speed operation and seed breakage rate height, also there is no the mechanical seed sowing device of the ripe fine grain defective ejaculation amount that is applicable to sowing at present.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, stable, without seed breakage, can realize the small-sized seed hill-drop feed run of small-sized seed defective ejaculation amount sowing.

The purpose of this utility model is achieved in that a kind of small-sized seed hill-drop feed run, it comprises bunch planting wheel rim, bunch planting wheel rim inside is seed chamber, multiple sowing ports distribute around bunch planting wheel rim, the arranged outside duckbilled dibbler of each sowing port, it is characterized in that: the inner side of each sowing port arranges inoculator, inoculator is made up of the cover body and the groove type inoculation tongue that are buckled on sowing port, ladles out kind of a spoon in the setting of inoculation tongue correspondence position.

Described kind of the spoon of ladling out can be by injection molding, also can be by sheet metal punch forming, and it is made up of spoon seat and outward extending 1～4 spoon head with fixing hole.When multiple spoon head, the size of its spoon head is by gradient setting, and during as four spoon heads, the size of spoon head is arranged to hold 2 seed-grains, 3 seed-grains, 4 seed-grains, 5 seed-grains.In use, only have a spoon head to be aligned in the work of inoculation tongue, such being designed with is beneficial to the convenient amount of sowing of adjusting.

Further, described bunch planting wheel rim is made up of rotating disc and fixing dome, and rotating disc and fixing dome snap together the seed chamber that forms sealing, on fixing dome, grain conductor is set, and grain conductor top connects seed-box.

Further, seed observation window is set on fixing dome, on observation window, cover transparency cover.

Seeding principle of the present utility model:

Seeding of the present utility model is to complete by being arranged on the inoculator of seed chamber inside and ladling out kind of a spoon.

1) sowing port is in the time of the bottom of bunch planting wheel rim, and kind of the spoon of ladling out that should sowing port is ladled out to upper seed, and cover body that should sowing port inoculator is covered to sowing port, and the reason of bunch planting wheel rim rotation, can directly not enter seed in cover body in addition;

2) when sowing port is before the top of bunch planting wheel rim, the seed on should the inoculation tongue of sowing port inoculator can be poured on and be ladled out in kind of spoon or seed chamber, on inoculation tongue, can not leave seed, can also further ensure that the spoon head of ladling out kind of spoon is full of seed;

3) when sowing port is after the top of bunch planting wheel rim, the seed of should sowing port ladling out in the spoon head of kind of spoon is poured on the inoculation tongue of its correspondence, the seed on inoculation tongue enters in the sowing port that cover body covers again,

4) sowing port is in the time of the bottom of bunch planting wheel rim, and the seed in sowing port enters in duckbilled dibbler and realizes precision drilling, and kind of the spoon of ladling out that should sowing port is ladled out to upper seed again.

The utility model compared to the prior art its advantage is:

Seeding of the present utility model is to complete by being arranged on the inoculator of seed chamber inside and ladling out kind of a spoon.Naturally fill the spoon head of ladling out kind of spoon by the gravity of seed completely, then by the process of natural landing, seed is entered in sowing port and duckbilled dibbler, overcome prior art and caused the injury to seed crush and grind by the relative motion seeding of mechanical part.

Described inoculator and to ladle out kind of spoon simple in structure, cheap, can be by injection molding, also can be by sheet metal punch forming.Do not need complicated power transmission structure.

It has solved a difficult problem for small-sized seed defective ejaculation amount sowing, stable, quantitatively accurate, there will not be sky to broadcast the phenomenon of being short of seedling.
