Description
Technical field
The utility model is related to the feed mechanism for seed in a kind of agricultural mechanical field, and in particular to a kind of novel pneumatic formula essence amount row
Device is planted, the precision drilling of vegetable seeds is realized.
Background technology
China is vegetables producing country and country of consumption maximum in the world, while be also Vegetables Exportation state maximum in the world,
It is that nearly 20 years yield of vegetables increase most, most fast country.The current China's Vegetable gross output value has surpassed 1.2 trillion yuans, accounts for planting industry
Gross output value ratio accounts for the 14% of farmers' per capita's income more than 33%, is the second largest farming produce that grain is only second in planting industry
Industry.Counted according to planting industry management department of the Ministry of Agriculture, vegetables have plantation in national each province and city, with Shandong, Jiangsu, Henan, wide
The provinces and regions such as east, Sichuan, Hebei are main producing region, wherein small particle seed vegetables(Chinese cabbage, spinach, baby cabbage, rape etc.)Growing surface
Product is most wide, has the call, and is most one of species of promotional value in vegetables.
At present, China's small particle vegetable crop planting patterns mainly uses 3 kinds of artificial broadcast, culturing and transplanting seedlings and Mechanical direct sowing
Mode, but domestic most regional vegetable cultivations are also main based on traditional artificial broadcast, and Mechanization sowing is less than 15%, and machine
Toolization sowing integral level is not high, it is necessary to the technical problem solved is also more, the expansion of serious restriction China vegetable cultivation area.
The special material characteristics such as vegetable seeds particle diameter is small, light weight, cracky govern China's vegetables Mechanization sowing
The development of technology, sowing of vegetable machineryization degree is constantly in relatively low level and degree, and feed mechanism for seed is the key of seeder
Core component, its performance directly influences seeder work quality and performance, and can seeder meet the requirement of seeding technique very
The working condition of feed mechanism for seed is depended primarily in big degree, therefore develops the small particles such as suitable Chinese cabbage, spinach, baby cabbage, rape
The feed mechanism for seed of seed turns into the key for improving sowing of vegetable machineryization level.Conventional small particle seed precise seeder has machinery
Formula and Pneumatic type, mechanical seed sowing device include outer groove wheel, nest eye wheel type, finger-clipped etc., with it is simple in construction, cheap,
Easy to operate the features such as, but it is strict to the requirement of seed appearance and size, and easily wound is planted, and realizes that monoseeding is difficult, it is difficult to realize granule
Footpath vegetable seeds precision drilling.Pneumatic seeding apparatus mainly uses the action effect of air-flow, and seed is blowed or adsorbed,
Make seed it is anticipated that rule move.Compared with mechanical, because the rigidity of airflow function is small, can effectively it reduce pair
The mechanical damage that seed is caused, can preferably adapt to the change of shape of the seed, easily realize high-speed job, be small particle vegetable seed
The direction of sub- feed mechanism for seed development.
The discharge plate of current driven sucking precise seeder is generally the form of single suction hole, such as a kind of small malt extract of Pneumatic type
Seeder(The patent No. 201110078344.0), have the single type hole being distributed uniformly and circumferentially, the seeding on discharge plate
Seed is adsorbed in type hole and it is moved with discharge plate by device using negative pressure, then separates negative pressure and in gravity by unloading kind of device
Seeding is realized under effect.Such feed mechanism for seed without use malleation to the seed adsorbed on suction hole due to blowing, and seed exists
Because inertia easily causes charge seed inaccurate during quick motion;In addition only have single inhale on the seeds sucker of feed mechanism for seed to plant
Hole, suction hole quantity is more, and narrow and small and no auxiliary conducting device is spaced each other, easily causes to fill and plants incomplete.
