Description

Air-suction precision sowing device

Technical field

The present invention relates to a kind of a kind of air-suction precision sowing device that can be completed to rice paddy seed Precise sowing.

Background technology

Rice is one of China's staple food crop.Paddy machinery plantation is the important component of China's mechanized agriculture.Traditional implantation methods are that first seedling is broadcasted sowing in rice seedling bed or seedling is sowed by seedling cultivation machine, then by artificial or rice transplanter in big field rice transplanting.Progressively apply in recent years and promote manually or mechanically in big field rice transplanting, new requirement (precise sowing seedling) is proposed to seedling cultivation.However, being rice transplanting or rice transplanting, it is required for cultivating of the right age strong seedling using advanced method of raising seedling, to establish the basis of high yield, so proposing requirement higher to seedling equipment；The seeder of seedling is presently used for, mostly using outer groove-wheel, interior sheave or pocket wheel mechanical formula dispenser.

But these existing Sprout cultivation seeders, its seeding quality is undesirable, it is mainly reflected in that seeding accuracy is not high, lack of homogeneity, hole rate is high, it is impossible to meet per the required precision of seed of 2~3, cave;Due to mechanical friction and squeezing action, easily wound is planted, and becomes dead.

The content of the invention

For a variety of problem for overcoming existing Sprout cultivation seeder to exist, the present invention provides a kind of air-suction precision sowing device.

The technical solution adopted for the present invention to solve the technical problems is：The air-suction precision sowing device includes motor, row's Nutrition Soil part, limiting plate, air-suction parts, change-over switch, source of the gas, seed pan shake table, sowing frame, during sowing, seed pan is placed on shake table, after shake table vibration, seed just produces upthrow to move in seed pan, inhales the suction that each aperture is produced on kind of plate and holds seed, then will inhale kind of a plate and moves on to seedling-cultivation plate top appropriate location, source of the gas air-flow is blocked again, seed is fallen into each taper hole of seedling-cultivation plate by deadweight, and ensures, per 2~3, cave seed, to complete and once sow work.

Aspirated-air type air-suction parts include inhaling kind of a plate, air chamber, change-over switch, adapter, limiting plate, aspirated-air type air-suction parts are placed on limiting plate, after seed vibrations in seed pan are got up, inhale each aperture on kind of plate and held the seed of upthrow by the suction that air chamber negative pressure is produced, then will inhale kind of a plate and move on to seedling-cultivation plate top appropriate location, source of the gas air-flow is blocked again and negative pressure is discharged, and seed leaves suction kind plate and falls into each taper hole of seedling-cultivation plate by deadweight.

Change-over switch includes reversing plate, takes over, valve hole plate, air chamber, and when source of the gas and air chamber are opened, air chamber forms negative pressure, inhale and plants;When air chamber and source of the gas path cut off, air chamber is communicated with outside atmosphere, and negative pressure is discharged rapidly, and seed falls into seedling-cultivation plate by deadweight.

The beneficial effects of the invention are as follows：The air-suction precision sowing device completes the operation to rice paddy seed Precise sowing, injuring-free seed high with seeding accuracy；Structure is novel, cannot be only used for rice nursing seedlings seeding, slightly transforms, that is, can be used for the seeding and growing seedling of greengrocery seed；Both it is manually actuated, again can mechanization, automation mechanized operation the features such as.

Specific embodiment

In Fig. 1, air-suction precision sowing device includes motor, arranges Nutrition Soil part, limiting plate, air-suction parts, change-over switch, source of the gas, seed pan shake table, sows frame, wherein when sowing, seed pan is placed on shake table 7, after shake table vibration, seed just produces upthrow to move in seed pan, is separated from each other between making seed；Each aperture on kind of plate is inhaled to be held the seed of upthrow by the suction that air chamber negative pressure is produced, then kind of a plate will be inhaled and moves on to seedling-cultivation plate top appropriate location, the air-flow of source of the gas 6 is blocked again and negative pressure is discharged, and seed leaves suction kind plate and falls into each taper hole of seedling-cultivation plate by deadweight, completes and once sows work；Motor 1 drives row's Nutrition Soil part 2 to discharge Nutrition Soil in seedling-cultivation plate, and seedling-cultivation plate 8 can be carried out coming and going conveying on sowing frame with machine driving；The key problem in technology of this seeding apparatus is each point uniformity for making the upward sling movement of seed in shake table seed pan, and seed is separated from each other, and in " boiling " state, so that seed is attracted on suction kind each aperture of plate, hole is reduced as far as possible；The aspiration power of each aperture on suction kind plate is uniform and can hold seed, it is ensured that per 2~3, cave seed.

In fig. 2, including inhaling kind of a plate, air chamber, change-over switch, adapter, limiting plate, wherein aspirated-air type air-suction parts are placed on limiting plate 4-5, after the seed vibrations in seed pan are got up, each aperture on kind of plate 4-1 is inhaled to be held the seed of upthrow by the suction that air chamber 4-2 negative pressure is produced, then kind of a plate 4-1 will be inhaled and moves on to seedling-cultivation plate top appropriate location, then blocked source of the gas air-flow and discharge negative pressure, seed leaves suction kind plate and falls into each taper hole of seedling-cultivation plate by deadweight.

In figure 3, including reversing plate, adapter, valve hole plate, air chamber, it is arranged between air chamber 5-4 and adapter 5-2, and two valve hole plate 5-3 are respectively and fixedly connected to plenum roof pipe end and adapter end face, forms fixed interlayer, reversing plate 5-1 is placed between two valve hole plates, respectively there are three holes on two valve hole plates, there is a hole on reversing plate, reversing plate moves left and right the conversion for realizing gas circuit；When source of the gas and air chamber are opened, air chamber forms negative pressure, inhale and plants;When air chamber and source of the gas path cut off, air chamber is communicated with outside atmosphere, and negative pressure is discharged rapidly, and seed falls into seedling-cultivation plate by deadweight.
