Abstract

The utility model relates to a liquid medicine spraying device for killing pests, and the liquid medicine spraying device for killing pests is the improvement of the medicine spraying gun of the existing sprayer. The utility model is characterized in that a spraying head for spraying can be replaced by a jet spraying head; the rod of the medicine spraying gun is made into a plurality of pipes which can be mutually connected; the switch handle of the medicine spraying gun is changed into a handle with a hand-operated piston pump, and thus the length of the gun rod of a sprayer can be adjusted as required. Medicines can be applied to the bore pests of trees in a fixed point mode, and formulation rate can be controlled. The utility model has the advantages of easy use, high work efficiency, favorable disinsection effect, no liquid medicine waste, simple structure and low cost. The liquid medicine spraying device can be used by matched with the existing sprayer.

Description

Medicinal liquid spraying device for killing pest

The utility model belongs to the architecture advances to the liquid medicine ejection device that is used for kill pests.

Be used for the device for administration of drugs of plant insect control at present, modal is back of the body formula sprayer, because its medicine spraying gun bar is short, to spray area big, makes it be mainly used in the extermination of disease and insect pest of crops.And for the trees insect, especially eat into bar class pest (as longicorn, carpenter moth, clearwing moth etc.) and do not have special injection device for administration of drugs, be to carry out large tracts of land with sprayer or large-scale sprayer to spray at first, it is big to have the spray survival dose like this, the problem that insect can not be killed in the moth bar can only be killed the insect of blade face and exposed part; The way of malicious label and malicious excellent smoked kill had been proposed afterwards, be swab (rod) to be placed in the insect channel come kill pests, its killing effect is fine, but workload is very big, operating personnel's certain danger that climbs up a tree, channel for branch, treetop and higher part can only be to be unable to reach, so the effect of desinsection is not thorough.

The purpose of this utility model is to design a kind of liquid medicine ejection device of killing moth bar insect that can be used in, and solving above-mentioned existing problems, and it also can be used as common sprayer.

Feature of the present utility model is that the medicine spraying gun that has sprayer now is improved, the one, can change spraying nozzle into fluid jet nozzle; The 2nd, barral of a gun is made some joints can interconnective pipe; The 3rd, the switch knob of medicine spraying gun is changed into the handle that has syringe.

The utlity model has following advantage from above-mentioned feature as can be seen: (1) can connect and dismantle easily owing to every joint gun barrel, so height according to the pest damage position, adjust the length of medicine spraying gun bar, it is easy to use, work efficiency is high, especially have overhead superiority, be suitable in recent years the characteristics of moving on some moth bar insect position, exempted the danger of climbing up climb down arduous and bringing thus; (2) because spraying nozzle and fluid jet nozzle can exchange use, after fluid jet nozzle is installed, can carry out herbicide placement to moth bar insect, after changing spraying nozzle, can carry out spray pesticide to the insect of exposed surface; (3) because the moving piston pump of the power armrest of spray medicine, therefore can control spray value with feel, or limit the maximum spout dose with the structure of syringe itself, so just can make size adjust formulation rate according to the worm of insect, both guaranteed to kill off the insect pests, do not waste soup again, help reducing the dispenser cost; (4) because it is simple in structure, with low cost, can with the existing general supporting use of sprayer, and manipulate very convenient, so be easy to promote the use of.

Accompanying drawing 1 is the user mode figure of the designed liquid medicine ejection device of the utility model, and accompanying drawing 2 is the example block diagram of designed syringe.1 is shower nozzle among the figure, and 2 is the medicine spraying gun bar, and 3 is the syringe pump housing, and 4 is depression bar, and 5 for connecting flexible pipe, and 6 is spray tank, and 7 is check valve, and 8 is piston, and 9 is pump cover, and 10 is return spring, and 11 is pole.Below in conjunction with accompanying drawing the method for manipulating of the present utility model is described.Before use, the handle of common sprayer is unloaded, change the handle that has syringe, determine to install the length of gun barrel as required and select to install shower nozzle, the soup for preparing is added spray tank, cover lid, (can add upward pressure to spray tank) by the sprayer air pump, the depression bar of the moving piston pump in continuous then floor sprays from shower nozzle up to soup, and the examination spray several times, check whether each several part leaks medicine, promptly begin to operate dispenser, how much deciding on the worm order of formulation rate should be unloaded each several part after the use, with flushing with clean water, and dry, put dry place and preserve, in case get rusty.

Embodiment of the present utility model as shown in the figure, fluid jet nozzle is the same with spraying nozzle can be connected with the barral of a gun top, just the soup of ejection is a jet-like, as injection needle, can metal or plastic production; Barral of a gun pipe connected mode each other can adopt screw butt joint, nut socket and many structures such as articulate; Syringe is actually the unidirectional water aspirator structure of hand, import and export at pump respectively have a check valve, one piston is arranged in the pump housing, lid is arranged on the pump housing, import and export and all communicate with plunger shaft, the rear end of piston has a connecting rod to stretch out outside the pump housing, is connected with depression bar, and the front end of depression bar is connected with pole, press the other end of depression bar like this, just can piston be depressed by connecting rod, gas or liquid in the plunger shaft are pumped out through check valve, under the effect of return spring, piston is pushed (drawing) and opens, form negative pressure in the plunger shaft, soup is inhaled into by another one-way pump, circulates with this; Return spring can install in plunger shaft, also can be enclosed within on the connecting rod, or between pump cover or handle and the depression bar; The adjusting of pump output has dual mode as can be seen, and the one, the size in regulating piston chamber, the 2nd, the length of regulating piston stroke, the second way are more practical.The frame mode of regulating piston stroke has, and is with pad in pump housing bonnet or on the outer connecting rod, and the thick more stroke of pad is short more; Or movable lining bar is arranged at the lower device of depression bar pressure side, and lining bar makes depression bar can not be pressed onto the end, and the stroke that moves depression bar on the lining bar is short more; Syringe can select for use metal or (with) plastic production.

Claims

1, a kind of liquid medicine ejection device that is used for kill pests, include spray tank with medicine spraying gun and be connected flexible pipe, it is characterized in that, can replace spraying nozzle with fluid jet nozzle, can be made into some energy-conservation interconnective pipes to the medicine spraying gun bar, the switch knob of medicine spraying gun can change the handle that has syringe into; Described piston pump is the unidirectional water aspirator structure of hand, import and export at pump respectively have a check valve, piston is arranged in the pump housing, lid is arranged on the pump housing, import and export all communicate with plunger shaft, piston rear end has connecting rod to stretch out outside the pump housing, be connected with depression bar, the depression bar front end is connected with pole, presses the other end of depression bar, just can piston be depressed, and have return spring can make the piston return by connecting rod.
