Description
Technical field
The present invention relates to agricultural equipment, particularly relate to a kind of Oryza glutinosa precision drill.
Background
In recent years, there is a growing awareness that the nutritive value of Semen setariae.Whole nation consumption figure is every year with the speed increment of three times.Kind
Plant the income of one mu of Oryza glutinosa, exceed 35 times of Semen Maydis.But owing to the seed of Oryza glutinosa is the least, the mu application rate of most farmers
Typically can only control to 46 jin the most.The preferable old farmer of technology, also can only control at about 3 jin.Plant one mu of Oryza glutinosa,
Need to put into the time of 56 days, and body hands dialling except the unnecessary paddy of more than 600,000 100 ten thousand strains one by one of must squatting down
Seedling.Summer is scorching, and squatting down for a long time and uprooting paddy Seedling between going down on one's knees is to feel bad very much really, and Gu Nong almost squat for a moment, kneel for a moment
Alternately change paddy Seedling between posture, dizzy brain of really swooning when they stand up and unfold.Have and be: only know that the price of rice is high, who
Know that thinning is difficult！Plant one or two mu, kneel ground more than ten day！
For many years, the exploitation of Oryza glutinosa seeder is never stopped, although so-called Oryza glutinosa on sale sowing on market in recent years
Machine, but existing Oryza glutinosa seeder generally exists and easily Oryza glutinosa is caused mechanical injuries, goes out grain uneven the most very difficult
Ensure that single Oryza glutinosa keeps at a certain distance away the technical problem of sowing so that Oryza glutinosa is planted uneven after sowing, or interval is big,
Be spaced little, and Oryza glutinosa impaired after cannot emerge.
Summary of the invention
The present invention solves that generally there is Oryza glutinosa in current Oryza glutinosa seeding process is easily subject to mechanical injuries, goes out grain inequality
The even particularly technical problem of sowing it is difficult to ensure that single Oryza glutinosa keeps at a certain distance away, it is provided that a kind of Oryza glutinosa precision drill.
The present invention adopts the following technical scheme that realization: a kind of Oryza glutinosa precision drill, including horizontally disposed sowing

Connecing, the front end of activation lever (7) is provided with lever actuated tooth (9).
Wherein, the middle part of described seeder mechanism (1) is fixed with the seeds chamber (10) of an equal opening of upper and lower side, described
Seeds chamber (10) is internally located at the upper level of seeder mechanism (1) and is provided with dividing plate and is divided into upper and lower two by internal for seeds chamber (10)
Chamber；Epicoele is as holding kind of a chamber (11), and cavity of resorption is as going out kind of a chamber (12).
" plumule is dampened, is wiped skin, breakage, brush to the mechanicalness of seed to present invention eliminates current domestic and international various seeders
Nest empty, embedding, be short of seedling, bunch Seedling " etc. many defects, design principle is accurate, and using method is simple.Capture " the small-sized seed such as Oryza glutinosa
Simple grain is sowed, spacing sets, individual plant is emerged " technical barrier.Eliminate the sowing of little grain seed " Seedling squeezes, Seedling is waste, Seedling is weak,
Seedling is thin, root is hindered in thinning, take a lot of work, time-consuming, the underproduction, the reduction of income " puzzlements in thousand！Incorporate " dry ground does not enter ditch, and wet soil does not go out ridge, under
Planting wet soil layer, the depth is the most uniform.Have that emergence rate is high, the even Seedling of Seedling complete, seed manure Seedling is strong, distance regulation " etc. technical spirit.Sowing effect
Rate is more than 15 times of artificial seeding, saves thinning for every mu and throws work 45 days；Establishing in large scale every mu saves artificial thinning expense
400 500 yuan.And because of individual plant emerge sturdy every mu volume increase 10 20%.Machine weighs 6 kilograms, and fault is few, devoid of risk, simple in construction,
Carrying portable.Collection " saving of labor, save plant, save time, laborsaving, province's moisture in the soil, preserve soil moisture, save fertilizer, water-saving, Miao Yun, Miao Qi, Miao Quan, Miao Zhuan, of fine quality,
Volume increase " in one.It is the head " emerged best in quality " of the small-sized seeds such as current Oryza glutinosa, vegetable, Herba Medicaginis herbage, Chinese crude drug, lawn
Select seeder.
