Abstract
The utility model discloses a positive pressure type medicine mixer, which comprises a hollow throat of a medicine mixer, and the hollow throat comprises a water inlet and a water outlet. A liquid inlet opening is communicated between the water inlet and the water outlet, the liquid inlet opening is communicated with a medicine storing chamber of a physic liquor tank in which a pressurizing chamber with variable volume isolated from the medicine storing chamber is also arranged, and the pressurizing chamber is communicated with a water inlet of the medicine mixer through a pressurizing pipe. Physic liquor is pressed in and mixed by positive pressure by the utility model, shrinking hole diameter of the hollow throat of the medicine mixer can be larger, and thus pressure loss is obviously decreased. Power distribution designed to a succeeding part of an integral water-spraying system has wider margin thusly.
Description
The utility model relates to supporting agricultural chemicals mixing arrangements such as a kind of soup mixing arrangement, especially a kind of engine-driven atomiser, belongs to agricultural machinery technological field.
The effect of medicine mixer is that soup is mixed with water, is transported to spray gun again, is sprayed onto on the crop, to reach the purpose of prevention and elimination of disease and pests, cover crop.The performance of medicine mixer is not only directly determining the parameters such as uniformity of soup, also affect spray gun output pressure etc., so medicine mixer is one of core component of various engine-driven atomisers.Known medicine mixer is suction type, its basic structure as shown in Figure 1, according to bernoulli's equation

wAs can be known, when water under high pressure entered medicine mixer and arrives the 2-2 cross section from the 1-1 cross section of import, because the aperture diminishes rapidly, flow velocity improved greatly, thereby produces negative pressure, and soup is sucked by upright opening, mixes with water under high pressure, and the outlet from the 3-3 cross section is transported to the spray gun again.The applicant is to shrinking aperture 2,2.2,2.5,3 millimeters, 10 ° at spray angle, 16 °, 22 °, nozzle and nozzle carrier gap 0.4,1.4, various suction type medicine mixers such as 5 millimeters divide into groups to test the back and find, there is following problem in this medicine mixer: the shrinkage hole footpath directly influences the soakage of soup, when the contraction aperture is 3 millimeters, can't form negative pressure, can not suck soup, and the contraction aperture is more little, crushing is big more, for example shrinking 2.2 millimeters in aperture, crushing when specified rifle is pressed 1.5MPa makes like this that up to 0.75MPa follow-up spraying machine power distribution is very difficult, and this problem is troubling the spraying machine design for a long time.
In the prior art, the applicant does not find to adopt the medicament-mixing device of malleation principle.When being retrieved, the existing patent of close technology finds, the applying date is that 85.10.08, application number are that 85204244 Chinese patent " positive-pressure type domestic shower " discloses a kind of water-water jet, two running water carrier pipes are arranged on this device, a pipe inserts the jug bottom, give the pressurization of the hot water in the jar, hot water is extruded from outlet, and the effect of another pipe is running water is mixed with the hot water of extrusion and to export, and its goal of the invention is to make mixed water temperature not be subjected to the influence of tap aperture size.Though this water-water jet is by the malleation principle, the hot water in the jar directly sneaked into running water by the water pipe of insertion jug, obviously can only be used for liquid of the same race, can not be applied to the medicament-mixing device that heterogeneity liquid need be mixed.
The purpose of this utility model is: the problem at above-mentioned prior art exists proposes a kind of mixed medicine good uniformity and the little positive-pressure type medicine mixer of crushing.
In order to achieve the above object, positive-pressure type medicine mixer of the present utility model comprises the medicine mixer trunnion that contains water inlet, delivery port, be communicated with inlet opening between the described entery and delivery port, inlet opening is communicated with the drug storage chamber of medicine liquid tank, also be provided with the variable volume booster cavity of isolating with the drug storage chamber in the described medicine liquid tank, described variable volume booster cavity is connected by the water inlet of forcing pipe with the medicine mixer trunnion.
When positive-pressure type medicine mixer of the present utility model is worked, the press water of medicine mixer trunnion water inlet flows to delivery port on one side, flow to the booster cavity of medicine liquid tank on one side through forcing pipe, make booster cavity oppress the drug storage chamber all the time, and soup is extruded from inlet opening, evenly mix with the current that flow to delivery port by medicine mixer trunnion water inlet.Because soup relies on malleation to be pressed into mixing, so the contraction aperture of medicine mixer trunnion can be bigger, thereby has obviously reduced pressure loss.Like this, make the power distribution of whole spraying system further part design have the nargin of broad.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the whole system schematic diagram that adopts Fig. 1 embodiment medicine mixer.
As can be seen from Figure 1, this positive-pressure type medicine mixer comprises the medicine mixer trunnion 15 that contains water inlet a, delivery port b, between entery and delivery port, be communicated with inlet opening c, this inlet opening c is communicated with the drug storage chamber d of medicine liquid tank 9, in addition, also be provided with in the medicine liquid tank 9 by the variable volume booster cavity e of pressing plate 4 with drug storage chamber d isolation, this booster cavity e is connected with the water inlet a of medicine mixer trunnion 15 by forcing pipe f, pressing plate 4 can move up and down along the inwall of medicine liquid tank 9, thereby changes the volume in two chambeies.
Each sign flag among Fig. 2 is as follows: 5-pond, 6-water pump, 7-Pump pressure meter, 8-pressurizing valve, 9-medicine liquid tank, 10-pressure-relief valve, 11-crushing table, 12 1 rifles are pressed table, 13-spray gun, 14-control valve, 15-medicine mixer trunnion, 16-differential pressure indicator.By this figure as can be seen, during actual enforcement, be provided with pressurizing valve 8 in the forcing pipe, between medicine liquid tank 9 and the medicine mixer trunnion 15 control valve 14 be housed, the adjusting of the flow of being more convenient for is like this controlled.After water pump 6 work, passing through to be responsible for when medicine mixer trunnion 15 supplies water, also the forcing pipe through pressurizing valve 8 places supplies water to the booster cavity e of medicine liquid tank 9, the result makes the drug storage chamber d pressurized of medicine liquid tank 9, volume dwindles, soup flows to medicine mixer trunnion 15 through control valve 14 under positive pressure, after water evenly mixes, transfer to spray gun 13.The crushing that experiment showed, the present embodiment medicine mixer is very little, and its flow velocity and the soup amount of being pressed into are almost linear, and it is very convenient therefore to regulate control.
Except that the foregoing description, the utility model can also have other embodiments.For example, variable volume booster cavity e makes leather bag, when forcing pipe supplies water to it, can make the drug storage chamber d pressurized of medicine liquid tank 9 equally.All this kind all belongs to protection domain of the present utility model.
