Embodiment
Agricultural chemicals seed dresser of the present invention comprises the feed bin 1 that has weight scale 16, the medical liquid container 2 that has containing mark 17, blower fan 3 and agitator 4; Blower fan 3 connects main air duct 6 tops, main air duct terminal horizontal and agitator 4 tangent communicating through airduct 5; Feed bin 1 logical charge tube 7 connects main air duct top, on the material pipe material valve 8 is arranged; Medical liquid container 2 lower ends are connected the main air duct end through pencil 9, and pencil top is provided with through swtich 10, and the pencil end is provided with micro-by-pass cock 11; The funnel-form cavity that agitator 4 is made up of the cylinder and the cone of its below; The cylinder side is provided with charging aperture 15; Charging aperture connects main air duct 6 ends along the cylinder tangential direction, is provided with air outlet 12 upwards in the middle of the cylinder, and the cone lower end is provided with discharging opening 13.Above agitator charging aperture place, be provided with the refining tongue 14 that seed and soup are all scattered.The discharging opening below is provided with the cabinet 18 that connects material.The cylinder of agitator is provided with air vent 19.On the medical liquid container 2 lid is arranged.
Feed bin, feed bin valve, material pipe, airduct, agitator, medical liquid container, pencil, soup through swtich, soup trace by-pass cock etc. that this agricultural chemicals seed dresser by blower fan, quantitatively has a scale are formed.
Blower fan is the power source of seed dresser, can produce the air quantity of certain intensity, keeps watch to drive a branch of raw material entering agitator through airduct.
Have in the feed bin of a constant volume to indicate certain scale, seed is placed on can see the amount that gets into agitator in the seed unit interval intuitively in the feed bin, and raw material passes through material valve; Advance feeding pipe; Rely on the self gravitation of seed, logical charge tube gets into main air duct, gets into agitator with the wind.
Agitator is formed by a certain size cylinder with by the cone of certain taper.Cylinder is provided with feed pipe (main air duct) along some tangential directions, and middle (promptly) is provided with air outlet, and cone small end (promptly) is provided with discharging opening.
Be placed with a certain amount of soup in the medical liquid container, container is marked with a certain amount of scale, can see the amount that gets into agitator in the soup unit interval intuitively.Soup gets into agitator through pencil.The medical liquid container below is provided with through swtich, and the longshore current tube side can be adjusted when finding that soup does not get into agitator on request to being provided with micro-by-pass cock near the agitator place at any time.
The soup inlet is installed on the feed pipe (main air duct), near charging aperture.
Medical liquid container is marked with containing mark accurately, can find to get in the unit interval dose of agitator intuitively, and inching switch is arranged, and can guarantee the more accurate consumption of soup like this.Next is heading straight for through swtich in working order, when inching switch goes wrong, can shut through swtich, and inching switch is keeped in repair.
Seed forms a branch of raw material through material valve in the feed bin of a constant volume, get into agitator through charge tube, main air duct, and the scale of a constant volume is arranged in the feed bin, can guarantee that like this seed amount on request gets into agitator.
The agitator charging aperture is that the power band seed and soup gets into agitator with wind.Vertically downward, after inlet port was interior, level was advanced under the effect of wind-force when soup just gets into; At this moment be stained with on the seed for the soup larger area, above the charging aperture place, be provided with the refining tongue, when soup advances; Stopped by the refining tongue; Soup disperses rapidly along the refining lingual margin, and a branch of raw material that the soup of dispersion is advanced is taken away, until the internal surface of column of agitator.Because charging aperture is positioned on some tangent lines of cylinder, and feeding opening is near the charging aperture, and is minimum by the suffered impact force of moistening raw material rapidly; Because raw material one gets into agitator; What run into is curved surfaces, and at this moment raw material is in the motion of spinning rapidly of inertia and action of gravity lower edge internal surface of column, so seed base-root and epidermis are difficult for being damaged and are stained with and have spared soup; The wind of rapid depressurization is discharged from exhaust outlet simultaneously, has realized separating of wind and pharmacopoeia.
Seed is in the internal surface of column motion of spinning; Crossed certain hour, seed arrives cylinder inner face and circular cone inner face joint, and its rotation (rolling) direction changes; At arrival discharging opening place; The seed whole body is soup entirely, and inner surface does not almost have remaining soup (promptly do not become drop, soup has been mixed on the seed entirely).Seed flows out along discharging opening, and seed dressing is accomplished.
