Description
Technical field
The invention belongs to agricultural mechanical field, is related to a kind ditch liquid spray-type seed bounce-proof device.
Background technology
Seeding operation plays vital effect in agricultural production, as the quick of seeding machinery sends out in world wide
Exhibition, seeding operation quality is also significantly improved, is mainly reflected in feed mechanism for seed and obtains updating optimization.But in reality
In field sowing operation process, seeding quality is but often difficult to reach expected requirement, and such as grain becomes away from qualified index, grain away from horizontal
Different coefficient etc..Main cause is, in actual seeding process, seed leaves the moment for falling into kind of ditch from feed mechanism for seed, can be with kind of a ditch
Soil collide, and produce a certain degree of spring and roll phenomenon, this process can be such that seed grain drops away from qualified index
Low, grain increases away from the horizontal coefficient of variation, seed level is inconsistent etc., reduces precision of charging seed, and causes whole seeding quality to decline, finally
Affect the yield of crop.
During seeding operation, in order to solve seed in the spring of kind of ditch and roll phenomenon, experts and scholars are ground
Study carefully, and there are Patents to report.
1st, " a kind of device for improving monodrill seeding accuracy " (Application No. 201410729942.3), in simple grain row
Kind of device is provided below one and leads discharge plate, lead it is even on discharge plate round surface be furnished with radial blind holes, leading discharge plate outside has shell, the top and bottom of shell
Portion respectively has flatly, and top opening is connected with single-kernel seed-metering device sowing port, and base opening is planting mouth.The seed Jing discharged from feed mechanism for seed leads discharge plate
The top opening of shell is fallen in the blind hole led in discharge plate, is tangentially dished out backward with leading discharge plate and going to bottom.Realize seed in planting mouth
Zero initial velocity fall, and planting mouth position it is low also limit seed spring rolling.
2nd, " a kind of high fabric bounce-proof ditching device such as wide cut " (Patent No. 201510493716.4), before inlay
Cutting edge before sliding blade type, can reduce advance resistance and prevent from twining grass, and the inside is provided with and dissipates kind of a plate, allows seed to scatter along wide bed of planting,
Projection is provided below and has marked fin on kind of bed, subtracted oligospermous spring, be conducive to the fixed point Even seeding of seed, realized
Contour Precise sowing.
