Description

Portable big lift high-voltage electric sprayer

Technical field

The utility model relates to a kind of spraying apparatus of eliminating agricultural pest or being used for the tea hill production of fruit trees of being used to, particularly a kind of portable big lift high pressure (direct current) power spraye.

Technical background

Existing commercially available power spraye kind is many, a kind of charged electric sprayer is disclosed as CN2254272Y, mainly by spray boom, shower nozzle, liquid filling cylinder, in liquid filling cylinder one side separate cavities, dc motor is installed, liquid atomizing pump (vacuum pump), accumulator jar, exist the storage dose little, the elevation and the lift that spray are limited, and it is low that switch is controlled automaticity, must integral body bear a whole set of spraying apparatus and cartridge case during the dispenser operation, cause operative employee's labour intensity big, when especially tea hill Guo Chang being sprayed, the dispenser difficulty is big, and effect is used in influence.And for example CN0023797 3.2 also discloses a kind of backpack direct current drive sprayer, it comprises housing, the filler, water inlet pipe, outlet pipe, battery, direct current generator, plunger type water pump pump housing assembly comprises driving gear, driven gear, push rod, cylinder barrel, be located at the suction check-valves in the cylinder barrel, piston and pitch brace, wherein water inlet pipe is communicated with cylinder barrel by the water inlet pipe interface, between cylinder barrel and outlet pipe, be provided with a voltage-stabilizing energy-saving device (forming) by energy storage tank and voltage-stabilizing and energy-saving valve body, it is good to have spray effect, the advantage that effect is high, the shortcoming that exists is a complex structure, the cost cost is big, can't cut off the electricity supply automatically during superpressure work, work can't be opened the switch conduction power supply after recovering normally automatically, and the working automation degree is low.

The utility model content

The purpose of this utility model is to provide a kind of lift big, and the spraying operation is light, automatic switch favorable working performance when big lift is worked, work efficiency height, effective portable big lift high pressure (direct current) power spraye.

The utility model is realized with following technical scheme: it comprises casing, liquid filling cylinder, water inlet pipe, outlet pipe, the spray boom shower nozzle that is connected with effluent pipe mouth, direct current generator, battery (storage battery), minitype high voltage spraying (water) pump assembly, it is characterized in that described direct current generator and battery are installed in the casing jointly side by side, the atomizing pump assembly directly is assemblied on the output shaft of direct current generator, be that the top of pump case is provided with one and can cuts off automatically or the normally closed pressure switch of electric contact of conducting motor power on the atomizing pump surface, when the ball valve switching knob of spray boom Handheld Division is closed, meeting (roof pressure contact button) causes the contact of this automatic normally closed pressure switch to be opened automatically with cut-out (motor) power supply when pressing superpressure (surpass authorized pressure) in the pump chamber, the motor atomizing pump is quit work, when the ball valve switching knob unlatching of spray boom Handheld Division is desired normally to spray operation, when press recovering normal pressure in the pump chamber when being in service pressure (or), the contact of automatic normally closed pressure switch can the auto-closing turn-on power, makes the motor atomizing pump operate as normal that resets automatically.

When actual design is implemented, the utility model also can further be specially: described liquid filling cylinder is to make a kind of outer separate member of casing that independently is placed on, but screen pack of tube port position attaching at liquid filling cylinder, water sucking mouth one termination of described water inlet pipe is gone in the independent external liquid filling cylinder, the other end of water inlet pipe is connected by being installed on the inlet joint on casing (case) body and the entrance point of atomizing pump (cylinder body), and the outlet of atomizing pump (cylinder body) then is connected with the spray boom shower nozzle with Great Wall Software's pipe and the operation thereof used as outlet pipe and be applicable to big lift length and height by the liquid outlet joint on the engine housing.

The utility model spray operation process is simple: to eliminate land for growing field crops or tea plantation, hillside fields, mountain area or orchard disease and pest is example, deployed liquid filling cylinder (cartridge) and portable sprayer are carried to suitable place: as land for growing field crops the edge of a field, or underfooting, hillside, press power switch and begin power supply by battery, direct current generator must be established the beginning running by cable, each parts work that motor output shaft directly drives in the atomizing pump assembly produces the vacuum pressure circulation, water inlet pipe begins to enter pump housing inner chamber vacuum chamber from the liquid filling cylinder aspiration medicinal liquid through the inlet joint, liquid after forming high pressure is again rapidly from pump housing outlet output, flexible pipe and spray boom shower nozzle through liquid outlet joint and tens of rice long (can reach 80 meters long) are connected, open spray boom ball valve switch, can spray operation.In spraying operation process; liquid output flow and the big I of atomizing area are got final product by the control operation of spray boom ball valve switch; can in 80 meters scopes of distance lift, spray operation; shut down, have a rest, mix medicine as need; need only close spray boom ball valve switch; controlled the stopping of liquid that enters pump chamber flowed out, and along with the high superpressure of voltage rise in the pump chamber, can cause the contact of pressure switch to open the autostop to cut off motor power automatically.Open when desiring normally to spray operation when the ball valve knob of spray boom Handheld Division, recover normal pressure along with pressing in the pump chamber, the contact of pressure switch is auto-closing turn-on power again then, makes motor restart the recovery operate as normal.Compare with the power spraye of prior art, the utlity model has: volume is little, and is in light weight, easy to carry at high mountain, Plain, operation easily, and is flexibly quick, it is good to spray atomizing effect, but the operation of efficient intelligent power can reduce labour intensity and agricultural chemicals loss more than 6 times.The per minute atomizing sprays flow and can reach 2 kilograms, and per minute atomized spray area can reach 30 square metres, inhales 5 meters of journeys, sprays height and can reach 13 meters, 80 meters of lifts.Can be used as agricultural chemicals, and the spraying operation of liquid such as foliage fertilizer of farm-forestry crops such as crops or tealeaves, fruit tree.
