Five, embodiment:
This gas broadcast dish by indenting tool 1, seed guiding groove 2, air chamber side cover 7, price fixing side cover 8, price fixing 9, seed absorbing plate assembly 5, seed absorbing plate seat 13, the piece 3 of holding one's breath, lead kind of impeller 6, clear clock scraper plate 20, seed absorbing plate seat 13, bearing 4 and 12, hollow shaft 11 and form.Indenting tool by moving duckbilled 29, decide duckbilled 28, duckbilled hinge 30 and plugboard 27 and form.
The air chamber side cover is installed on the hollow shaft 11 by bearing 4, on the plugboard 27 of indenting tool 1 seed guiding groove 2 is installed, and plugboard 27, seed guiding groove 2 link together by plugboard connecting bolt 14 and form circle body.Circle body is installed between air chamber side cover 7 and the price fixing side cover 8 with side cover connecting bolt 15, between price fixing side cover 8 and hollow shaft 11 price fixing 9 is arranged and is fixedly mounted on the axle.Between price fixing 9 and air chamber side cover 7 and hollow shaft 11, seed absorbing plate assembly 5, seed absorbing plate seat 13 are installed, lead kind of impeller 6; Clock scraper plate 20 clearly is installed between price fixing 9 and seed absorbing plate assembly 5; In the closed air chamber that air chamber side cover 7, seed absorbing plate seat 13, seed absorbing plate assembly 5 and hollow shaft 11 constitute, the piece 3 of holding one's breath is installed, and air chamber communicates with hollow shaft 11; Constitute by seed absorbing plate seat 13, seed absorbing plate assembly 5, air chamber side cover 7, circle body, price fixing side cover 8 and price fixing 9 and to deposit kind of a cavity, into kind of hole 21 is arranged on price fixing 9, and advancing inoculated tube 18 is installed on kind of the hole 21, on circle body, be fixed with more than one indenting tool 1, and the duckbilled on each indenting tool 1 with the lower seed hole on the corresponding plugboard 27 communicate, and each lower seed hole communicates with seed guiding groove 2, seed guiding groove 2 with lead kind of impeller 6 and communicate.
During work, gas is broadcast dish and is vertically broadcast the axle 11 of circling or whirl in the air by gas and be fixed on the sower, when seed flows into gas and broadcasts in the dish by inoculated tube 18, because the restriction of entering kind of hole 21 makes seed maintenance certain height in gas is broadcast dish.When gas is broadcast the face of land, rim (A to) is rolled forward, the negative pressure that the sower blower fan produces enters closed air chamber by connecting the hollow shaft external tapping, the seed suction hole that distributes on the seed absorbing plate 32 is produced negative pressure, gas is broadcast the negative pressure of the interior seed of dish by seed absorbing plate 32 seed suction hole places, hold corresponding seed respectively, and with the sowing circle body, lead kind of impeller 6, air chamber side cover 7 and price fixing side cover 8 together rotate, absorption seed in the rotating process of top, to adsorb unnecessary seed by clear clock scraper plate 20 removes, when being rotated further kind of dish below, enter and isolate the clear road 25 of planting, and by the piece 3 of holding one's breath source of the gas is isolated in the bottom, simultaneously, seed is at gravity, inertia force and isolation are unloaded under the effect in kind of road 25, seed unloaded to enter lead kind of impeller 6, seed is broadcast dish with gas and is led kind of impeller 6 and continue to move to price fixing 9 and sow and mouthfuls 26 seed fallen into outer course on the seed guiding groove 2, along with circle body continues to rotate up, seed is under the guide effect of gravity and the oblique ear of seed guiding groove 2 opening parts, flow into seed guiding groove 2 inside grooves, continue to move to gas and broadcast when coiling the front lower place, seed is led people's plugboard 27 lower seed holes flow in the duckbilled.The duckbilled 28 of deciding on indenting tool 1 inserts the face of land, broken hole on mulch film, and under the effect of moving duckbilled 29 pressing plates, open duckbilled, seed is broadcast in the soil.Continue motion, moving duckbilled 29 is closed duckbilled under the effect of deadweight and duckbilled spring 31, enters next working cycles, and whole cave formula seeding operation has just been finished in circulation and so forth.When being work, the peep pole 24 on the price fixing 9 inhales kind of situation and supplemental air flow in order to observe.When the seed of absorption on the seed absorbing plate 32 too much or when having the hole to produce, unclamp scraper plate and adjust bolt 19, adjust groove 23 along scraper plate and move, make scraper plate near and leave seed suction hole and get final product to suitable fixed-site.When sowing, to change impurity in seed variety and cleaning kind of the dish, inoculated tube set bolt 16 can be dismantled, downward-sloping inoculated tube 18 along hinge 17, be convenient to collect seed and impurity, behind for clearance the finishing, inoculated tube 18 is closed use bolt again, can carry out subsequent job after adding kind.
When the kind period of the day from 11 p.m. to 1 a.m of needs sowing different cultivars, as long as change respective aperture seed absorbing plate 32.For improving the mobile performance of seed, seed absorbing plate assembly 5 is provided with and stirs kind of nail 33 or do not have and stir kind of a nail 33.
When needs are adjusted spacing in the rows, dismantle circle body plate connecting bolt 14, increase or reduce the indenting tool 1 on the circle body, and plugboard connecting bolt 14 plugboard 27 corresponding hole site of packing into are fixed and form new circle body, after simultaneously adjustable impeller blade 34 of leading kind of impeller 6 also being made corresponding increase and decrease and integrated positioning, the supporting seed absorbing plate assembly 5 of packing into is assembled into supporting gas again and broadcasts dish and get final product.Increase indenting tool 1 and impeller blade 34 spacing in the rows and reduce, reduce indenting tool 1 and impeller blade 34 spacing in the rows and increase.
Above-mentioned gas is broadcast dish in order to reach serviceability and rational structure configuration preferably:
Indenting tool be pressing plate side's mouth indenting tool or pressing plate point mouth indenting tool or in open formula side's mouth indenting tool or in open formula point mouth indenting tool or laterally opened side's mouth indenting tool or laterally opened sharp mouth indenting tool.
The keying of duckbilled adopts the dead-weight pressing plate to open and close or elastomer opens and closes or cam body regularly opens and closes, and wherein, elastomer can be torsion spring, stage clip, extension spring, tower spring, leaf spring or rubber.Decide duckbilled and can be provided with catch, catch can connect with civilian hinge, and the flap of also available special dual-purpose one substitutes.The middle pin hole of hinge can default, and is used to install the duckbilled spring.
Seed guiding groove can be adjustable all-in-one-piece or knockdown.Seed guiding groove can be used on other seeders.Seed guiding groove and plugboard be for adopting clamped-in style, compression type, and bolt, pin, inserted, slot type fixedly mount.Lower seed hole limit on the plugboard is to have to prevent that secondary from filling the boss of planting or not having boss.
