Description

Portable mechanical atomiser

The utility model relates to plant protection mechanism.

The present employed equipment for plant protection in the vast rural area of China can't satisfy the demand of plant protection operation.As stretcher-mounted sprayer with engine drive,, be unfavorable for field transfer and patch operation because volume is big, machine weighs (85 kilograms), spray amount is big; As the power knapsack mist duster, machine weighs 26 kilograms, and operation is carried in personnel selection, and resemble summer and carry a chafing dish, heat but also tired not only, one meets the strong wind sky, can't dispenser; As widely used knapsack hand sprayer, because labour intensity is big, work efficiency is low, the modern requirement of incompatibility in the rural area.

The purpose of this utility model is to provide a kind of portable power driven sprayer, and it is the device of a kind of while preparating liquid and spray liquid.Can be widely used in the prevention and control of plant diseases, pest control of agricultural, forestry.

The technical solution of the utility model realizes as follows:

The utility model is made up of miniature gasoline engine, miniature peripheral pump, dispensation apparatus, injector head, frame etc.Miniature gasoline engine, miniature peripheral pump, dispensation apparatus are installed on the frame, and the spike more than 3 is arranged at the bottom of frame, and the output shaft of miniature gasoline engine and the driving shaft of miniature peripheral pump are coaxial.Dispensation apparatus is communicated with the water inlet pipe of miniature peripheral pump, on the delivery port of miniature peripheral pump reservoir chamber is housed, be connected with injector head on the outlet pipe of reservoir chamber outlet, and dispensation apparatus with spray tank can regulate to constituting between the water inlet pipe, observable path, miniature peripheral pump is gone up the reservoir chamber installed and the back-water valve (BWV) in the reservoir chamber and air bleeding valve thereof by its outlet and is reached self-priming.

Dispensation apparatus is made up of spray tank, burette chamber, dropper, grug transportation tube, switch, check valve, adjustment screw etc., dropper more than 1 is housed on the burette chamber, medicine stoste enters burette chamber by grug transportation tube, dropper in spray tank, adjustment screw is arranged on the dropper, tighten or unscrew path that adjustment screw can close dropper or the size of regulating the dropper path, the concentration that number is regulated spray liquid of dripping with the control soup, burette chamber is made with transparent material, dropper can see clearly Chu when dripping medicine in burette chamber, is convenient to accurately grasp the medicine liquid droplet number.

The shaft section of miniature peripheral pump amasss in 45 square millimeters, air bleeding valve is equipped with on the top of reservoir chamber, and back-water valve (BWV) is equipped with in the bottom, and the other end of back-water valve (BWV) is communicated with water inlet pipe, the import of reservoir chamber communicates with the delivery port of miniature peripheral pump, and the outlet pipe in its outlet is connected with injector head.Injector head adopts direct projection spray gun or 2 s' to 4 centrifugal sprinkler.

Advantage of the present utility model is as follows:

Back-water valve (BWV) and air bleeding valve are housed in the reservoir chamber in the utility model, have improved the self-priming performance of miniature peripheral pump.Prestart will be filled diversion, after the starting in the reservoir chamber for the first time, miniature peripheral pump just can be discharged the air in the inlet pipeline automatically, reach the purpose of self-priming, because miniature peripheral pump and miniature gasoline engine are coaxial, co-structured simple, in light weight, complete machine can be with portable transhipment.Can reach simultaneously the above pressure of 1.8 MPas, because the utility model is provided with a dispensation apparatus, can absorb water on the spot, automatic medicine-mixing as required, can be prepared the concentration of spray liquid at any time.It is easy to use, work efficiency is high, atomization quality is good, can be widely used in the prevention and control of plant diseases, pest control of agricultural, forestry.

With reference to accompanying drawing embodiment, the utility model is described in further detail:

Fig. 1: portable power driven sprayer structural representation.

Fig. 2: A-A figure.

Among Fig. 1: miniature gasoline engine (11), miniature peripheral pump (2), dispensation apparatus (21) are installed on the frame (18), there are 4 spikes (20) frame (18) below, a filter screen (19) is equipped with in the porch of water inlet pipe (17), and the delivery port of miniature peripheral pump (2) is equipped with reservoir chamber (4).Air bleeding valve (6) is equipped with on the top of reservoir chamber (4), back-water valve (BWV) (5) is equipped with in its underpart, the other end of back-water valve (BWV) (5) is communicated with water inlet pipe (17), the import of reservoir chamber (4) communicates with miniature vortex delivery side of pump (25), outlet pipe (3) is equipped with in its outlet, and outlet pipe (3) is connected with injector head (8).Dispensation apparatus (21) is made up of spray tank (9), grug transportation tube (10), (22), dropper (13), burette chamber (14), adjustment screw (12), switch (15), check valve (16) etc., and switch (15) and check valve (16) are installed between burette chamber (14) and the water inlet pipe (17).

Calculate by liquid proportion, dripping of medicine stoste per minute counted in 90 if desired, then only need open a dropper (13), when surpassing 90, determine to open the number of dropper (13) on demand, adjust adjustment screw (12) then, reach the former number of drops of needed medicine.When starting for the first time, turn on water storage chamber cap (7), to fill diversion in the reservoir chamber (4), because the elbow height of water inlet pipe (17) is concordant with the outlet (26) of reservoir chamber (4) and be higher than miniature vortex delivery side of pump (25), diversion will be full of pump chamber (23), tighten water storage chamber cap (7) then, starting miniature gasoline engine (11), impeller (1) rotates, air in the water inlet pipe (17) is inhaled in the pump chamber (23) and mixes with water, producing air-water mixture drains in the reservoir chamber (4), because air is light, just discharge outside the miniature peripheral pump (2) by air bleeding valve (6), part water enters once more in the pump chamber (23) after back-water valve (BWV) (5) flows into water inlet pipe (17) and mixes with gas, so moves in circles, after the air in the water inlet pipe (17) has been arranged, the water yield of miniature peripheral pump (2) increases, and the pressure in the reservoir chamber (4) increases.When pressure during greater than the spring pressure of air bleeding valve (6) in the reservoir chamber (4) and back-water valve (BWV) (5), air bleeding valve (6) and back-water valve (BWV) (5) are closed voluntarily, and water is depressed into injector head (8) ejection through outlet pipe (3).

After miniature gasoline engine (11) starting, during the normal water outlet of miniature peripheral pump (2) beginning, open switch (15), because water inlet pipe (17) produces negative pressure, check valve (16) is inhaled out, the soup of spray tank (9) lining is through grug transportation tube (10), dropper (13), burette chamber (14), switch (15), check valve (16), grug transportation tube (22) flows in the water inlet pipe (17), entering pump chamber (23) mixes with clear water, by adjusting the opening degree of switch (15), can control burette chamber (14) inner liquid medicine and enter the interior uniformity of miniature peripheral pump (2).When water inlet pipe (17) stopped into water, check valve (16) was closed under the promotion of spring, and soup stops to splash into.

As at paddy-field-working, this device can be placed Tanaka, filter screen (19) is inserted suction on the spot in the water, the operator hands injector head (8) and carries out operation.During transfer location, complete machine can be with portable transhipment.

Among Fig. 2: impeller (1), pump cover (28), the pump housing (29) all belong to the component parts of miniature peripheral pump (2) among Fig. 1, and shaft section (27) refers to remove between the pump housing (29) and the pump cover (28) the runner shaft section of impeller (1).
