In the time that the second driving gear 412 is meshed with the second driven gear 4222, because the first driving gear 412 diameters are less, the second driven gear 4222 diameters are larger, thereby when rotating, road wheel 31 within one week, drive the second driving gear 412 while rotating one week, the second driven gear 4222 being meshed with the second driving gear 412 rotates and is less than one week, thereby can slow down to the speed of sprayer unit pressurization, slowly promote the gas pressure of sprayer unit inner bin 11 inside, be convenient to adapt to differently condition, and reduce the labour intensity that promotes sprinkling wagon, comparatively laborsaving.
The concrete use procedure of a kind of hand-push type pesticide-spraying cart of the present embodiment is as follows: in the time promoting or pull the hand-push type pesticide-spraying cart of the present embodiment, the road wheel 31 of running gear 3 rotates, and drives the driving gear 41 being located on axletree 32 to rotate together.
By pulling the stay cord 56 of rigid cartridge 53 inside, make limited post 54 from the interior retraction of annular spacing groove 57, then by the axial push-and-pull rigid cartridge 53 along axletree 32, make sleeve 51 moving axially along axletree 32, now unclamp stay cord 56, in the time moving to correct position, limited post 54 enters in corresponding annular spacing groove 57 under the thrust of elastic component 55, now the driving gear 41 on axletree 32 is meshed with the driven gear 422 on power transmission shaft 42, and the rotation of axletree 32 is converted into the rotation of power transmission shaft 42, and further by being located at the first bevel gear 421 on power transmission shaft 42 and being located at engaging of the second bevel gear 431 on crankshaft structure 43, the rotation of power transmission shaft 42 is converted into the rotation of crankshaft structure 43.
More specifically, adjustable the first above-mentioned driving gear 411 is meshed with the first driven gear 4221, thereby can pressurize to sprayer unit 1 faster, the gas pressure of fast lifting sprayer unit 1 inside.Or regulate the second above-mentioned driving gear 412 to be meshed with the second driven gear 4222, thereby can slow down to the speed of sprayer unit pressurization, slowly promote the gas pressure of sprayer unit inner bin 11 inside, be convenient to adapt to differently condition, and reduce the labour intensity that promotes sprinkling wagon, comparatively laborsaving.
Crankshaft structure 43 is provided with the structure such as strip plate or disk 44, in the time that crankshaft structure 43 rotates, can promote pressure rod 63 by structures such as above-mentioned strip plate or disks 44 moves up and down, and and then promote to add tamponade 62 and move up and down adding pressure cylinder 61 inside, move towards unidirectional guide 7 directions of air-flow when adding tamponade 62, and in the time adding gas pressure in pressure cylinder 61 and be greater than the gas pressure in casing 11, be positioned at the gas that adds pressure cylinder 61 and can push ball sealer 72 open, thereby make the air-flow that adds pressure cylinder 61 inside by small end ventilation position, and further enter in casing 11 by large end ventilation position and air-vent, thereby increase the atomisation pressure of sprayer unit 1, now, pressure pad 621 have stopping of perforated metal platen 622 towards adding pressure cylinder 61 opening one end, the distortion that can not be distorted, thus can ensure air tight.
Move to maximum position when adding tamponade 62 towards unidirectional guide 7 directions of air-flow, and add gas pressure in pressure cylinder 61 when identical with gas pressure in casing 11, ball sealer 72 can be rolled to small end ventilation position place under the effect of gravity, and blocked, in the time adding tamponade 62 towards unidirectional guide 7 directions of air-flow reverse mobile, gas pressure in casing 11 is greater than the pressure that adds pressure cylinder 61 interior gases, thereby now ball sealer 72 is stopped up small end by gas position completely by the air extrusion in casing 11, pressure pad 621 does not have stopping of metal platen 622 towards one end of the unidirectional guide 7 of air-flow, ambient atmosphere with add the distortion that can be distorted under the pressure differential of pressure cylinder 61 internal gas pressures, from there is ventilation voids, thereby the gas in atmosphere can be entered into and be added pressure cylinder 61 inside by the hole on perforated metal platen 622.
By the continuous firing of above-mentioned pressue device 4, can in the casing of sprayer unit 1 11, accumulate large quantity of air, and the liquid medicine of oppressing casing 11 inside sprays from shower nozzle, realize spray medicine.
In the time that needs spray more agricultural chemicals in a certain plot, adjustable the first driving gear 411 and the first driven gear 4221 are meshed, and improve pressurization efficiency, also can drag back and forth in original place sprinkling wagon, and continuing provides pressure to flusher 1.
When been sprayed need to stop spray while wanting, can pass through variable speed operation assembly 5, regulate driving gear 41 to separate with driven gear 422, now can freely promote or pull sprinkling wagon, and can be to the gas storing apparatus conveying air of sprayer unit 1 inside.
Obviously, above-described embodiment is only for example is clearly described, and the not restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also giving exhaustive to all embodiments.And the apparent variation of being extended out thus or variation are still among the protection domain in the invention.
