Description
Technical field
The present invention relates to technical field of seeders, particularly relate to the special planter of a kind of electrostatic adsorption type cotton seed.
Background technology
At present, the nursery of the crops such as cotton, tobacco, vegetables mainly adopts point disk seedling growing.Because half/full-automatic tray seeder is expensive, and polygamy closes the complete sets of equipment pipelinings such as batch mixing, earthing, punching, there is the problems such as complicated operation, difficult in maintenance, transaction capabilities poor reliability.Therefore in production reality adopt the artificial operational method toward program request seed in the dish of cave, the shortcomings such as this operational method exists when taking a lot of work, labour intensity is large, efficiency is low more.In recent years, labour cost sharply rises, and program request operation accounts for seedling cost proportion and strengthens, and therefore, is badly in need of the seeder that structure is simple, simple to operate, affordable, precision are high, carrys out alternative manpower, improves sowing efficiency, to reduce seedling cost.
In the correlative study of existing manual tray seeder, there are some patent documents about sower, as follows:
Sower disclosed in Chinese patent CN2655605Y, CN95241502.X, CN2506057Y all based on dislocation hole principle, realizes mechanism's composition similar.Be characterized in sowing mechanism by containing kind of a plate, band kind of a plate, leak kind of a plate and form, be arranged in order up and down and be distributed as three layers, wherein, intermediate layer be moveable band kind of a plate, contains kind of plate and leak kind of a plate to be fixed on support, realizes sowing by the relative changing of the relative positions between three ply board.Plug-type tray seedling-culture seeding device disclosed in Chinese patent CN201360407Y is made up of kind of a case, Z-type plate, and the upper plate of Z-type plate and lower plate parallel clips, in the both sides up and down of kind of box plate, are planted box plate and fixed, and upper lower plate is twitched back and forth successively and realized sowing.
The shortcoming of above-mentioned multiple patent type is: 1) differ greatly due to seed size during work, during push-and-pull sowing and the direct rigid contact of upper and lower plates, easily hinders kind; 2), when seed is less, seed falls into continuously or by slotted eye, causes many; 3) put kind to complete with sowing point 2 ~ 3 operations, and non-once completes, efficiency is not high.
Chinese patent CN2256205Y discloses a kind of Dislocated point disk seedling growing hand operated seeder, be made up of the seeds discharging box of movement, scraper plate, dislocation plate, sowing is divided into two work steps, namely first pull seeds discharging box to scraper plate seeding, pull dislocation plate again, make the eyelet dead in line of dislocation plate and scraper plate, guide seed landing to coil to cave by plastic hollow conduit.Due to cotton seed broadcast before have and soak needs, guiding tube cannot guide wet kind of downslide, causes hole, and when two work steps are taken a lot of work, reduces operating efficiency; Multi-layer sheet superposes mutually simultaneously, is difficult to clear up eyelet when blocking up appears in seed, causes continuous hole.Chinese patent CN20081112 discloses a kind of suction disc throwing-vibrating type plug seedling-raising semiautomatic precision seeding machine, comprise frame, workbench, negative pressure aspiration mechanism, Sheng Zhongpan, its mainly by negative pressure be connected seeds sucker on suction nozzle draw seed, after cutting off source of the gas, negative pressure disappears, and seed is called in the dish of cave.This kind of method is got kind relatively reliable, but when air-flow distance suction nozzle is far away suction decay rapidly, cause cotton seed and port contact insufficient time easily leak and inhale or fall to plant.Meanwhile, negative pressure cut off after due to the hysteresis quality of sucker room pressure, seed time of naturally dropping from suction nozzle is oversize, and there is problem in suction nozzle mouth card.
Above-mentioned defect just, these sowers are not widely applied in production reality.
