Abstract
A portable automatic sucking and dispensing sprayer for killing the pests of crops by immunity is composed of pump, liquid medicine container, liquid medicine flowing observing chamber, liquid medicine flow control valve, water sucking tube with filter tip and nozzle. The sprayer has two flow-rate and flow-rate medicine liquid control valves, can obtain accurate medicine liquid mixture with different medicine proportions in the pump, and has a medicine liquid flow observation chamber capable of being monitored at any time. The sprayer can automatically suck and match the liquid medicine by using the water in the field, has small volume, light weight and more labor saving, and is convenient to operate.
Description
The utility model relates to a kind of sprayer that is used for crops immunity desinsection.
Existing agricultural knapsack sprayer is made up of sprayer and liquid medicine bucket.The water that proportions in advance and the mixed liquor of agricultural chemicals are fed into the liquid medicine bucket, then itself and sprayer are joined, and bear at operator's back with braces and carry out spraying operation.Operating personnel are bearing heavy liquid medicine bucket and are spraying for a long time, the labour intensity height, and physical demands is big, and operating efficiency must be low; Spraying operation carries out in advancing, usually because admixing medical solutions in the liquid medicine bucket rock and spatter on one's body, not only pollute clothes even insalubrity; After liquid medicine bucket inner liquid medicine used up, work stopped to get back to powder charge place time-consuming the taking a lot of work of pouring water of making up a prescription again.
In order to address the above problem, Chinese utility model patent specification 86204757 discloses a kind of automatic knapsack sprayer of joining of inhaling of agricultural chemicals that utilizes in water source, field and the sprayer.This utility model is with threeway element switches pump, medical liquid container and a mixed solution container.Pull rocking bar piston is moved, the water and the soup that suck in the water aspirator are mixed into mixed solution container.With the control of porous inserted sheet flow control valve movably medicinal liquid flow.Water inlet, medicine liquid outlet and mixed liquor import prevent to flow backwards with check valve.The effect of this utility model is to fetch water, alleviate operator's burden on the spot, reduces physical demands.
But this utility model adopts porous to move the inserted sheet flow control valve, and inserted sheet valve seal degree is poor, leaks easily, is difficult to reach medicine proportioning accurately, when medicinal liquid flow will harm the crops during greater than the medicine proportioning; When this utility model was adorned perfusion liquid before use, soup can pour three-way pipe, caused very burden, had just lost the effect of dose proportioning as not getting rid of the soup that pours; This utility model is a knapsack sprayer, and the back of the body can not find in time that after one's death soup blocks fault, causes crops not obtain should soup being arranged and causes disease.
The purpose of this utility model be to avoid the problems referred to above of the prior art and provide a kind of with the agricultural chemicals in water source, field and the sprayer inhale automatically compounding close, have accurate medicine proportioning control structure and soup circulation observation structure, do not have leak, volume is little, in light weight, the portable sprayer in labour-saving more.
Task of the present utility model is finished by following measures.
The utility model is made up of a pump, medical liquid container and medicinal liquid flow control valve.On piston tube one end in the pump piston and check valve are arranged, handle and shower nozzle followed in the other end first line of a couplet, seals the pump head with nut, prevents that piston from extracting out from pump.A support is arranged on the handle, fixing an end of tooth bar on the support, in the gathering sill on the other end insertion pump of tooth bar, tooth bar can slide in gathering sill.The stroke of the length of tooth bar and pump inner carrier pipe matches.The other end of pump connects with a three-way pipe, and the two ends in addition of three-way pipe join with filter-tipped suction hose and soup conduit respectively, at two joints--soup import and water inlet, a check valve are arranged respectively, prevent the refluence of soup and water.
There is the medical liquid container of a band ventilation hole pump top, and conduit one end inserts medical liquid container, and its other end and soup circulation observation ward join, so that observe the soup current intelligence at any time.Soup circulation observation ward is connecting a medicinal liquid flow control valve, and it is to be made of circular Flow-rate adjustment spool and current limliting spool.Regulating spool is regulated flow as the alternate channel area, regulating spool can be at it different hole of several diameters to be arranged radially, also can be that spiral propelling spool is regulated flow, there is the knob of a band dial regulating spool termination, flow-limiting valve core diameter with matching upwards has aperture, the break-make of control soup changes flow velocity and further controls flow, reaches desired medicine proportioning.There is a gear termination of current limliting spool, with the tooth bar engagement on the support.
One holds handle, and another holds pump, back and forth twitches, and tooth bar moves back and forth with handle, drives the current limliting valve core rotation by the rack-and-pinion engagement.According to the soup control valve hole reserved of different hole of diameter or screw propulsion upwards directly, mark corresponding medicine proportioning scale on the knob of its termination.Two spool position back to front can be obtained effect same.The medicinal liquid flow control valve of this second gear control can guarantee accurate medicine proportioning.
Soup circulation observation ward is made by transparent material, can observe the soup current intelligence at any time.
When the twitch piston tube is moved to the left, drive piston and be moved to the left, the pump inner chamber increases gradually, and cavity pressure is lower than atmospheric pressure, and this moment, the water in field entered the pump inner chamber by filter-tipped suction hose through check valve; Atmospheric pressure is by the blow vent of medical liquid container simultaneously, make soup be pressed into conduit, soup circulation observation ward, flow control valve, conduit, check valve, in three-way pipe, be mixed into the pump inner chamber with water, enter in the annular chamber of piston tube outer surface and the formation of pump inner chamber through check valve again, water medicine mixed liquor enters the piston tube inner chamber by the aperture on the piston tube, spray away through shower nozzle, pump inner chamber imbibition simultaneously, twitch and so forth, reciprocating motion of the pistons sprays desired water medicine mixed liquor in the shower nozzle.
Compared with the prior art the utility model has the following advantages: the utility model is that sprayer is joined in portable automatic suction, and simple in structure, volume is little, and is in light weight, easy to operate; The utlity model has a soup circulation observation ward, can grasp the soup current intelligence at any time; Adopt the medicinal liquid flow control valve of second gear control, guaranteed accurate medicine proportioning.
The explanation of accompanying drawing drawing:
Fig. 1, cutaway view of the present utility model;
Fig. 2, the A-A cutaway view of flow control valve of the present utility model.
The utility model is following will to be described in detail embodiment (in conjunction with the accompanying drawings).
