Abstract
The utility model relates to an electric sprayer, relating to the improvement of agricultural sprayer, which comprises a spray rod. A baffle is arranged in the barrel so as to divide the barrel into an upper liquid storing case and a lower machine case which is internally provided with an electromotive water pump, a storage battery and a control circuit. The water inlet of the electromotive water pump is communicated with the bottom of the liquid storing case; the upper end mouth of a tee is communicated with the water outlet of the electromotive water pump through a unilateral valve and the left and right end mouths at the lower end are respectively communicated with a water outlet pipe and a pressure reservoir; wherein, the water outlet is provided with a water control switch. The utility model is convenient to be operated without rocking the rocking rod with hand; turning on or off the tap of the spray rod can automatically make the water pump stop rotation or start work.
Description
Technical field:
The utility model relates to the improvement of agricultural atomizer.
Background technology:
The tradition agricultural knapsack sprayer needs one to hold spray boom during use, the another hand ceaselessly shakes rocking bar to give the air chamber pressurising, and peasant's labour intensity is big.Chinese patent (00237973 " a kind of backpack direct current drive sprayer ") has been introduced and has a kind ofly been driven water pump and need not the technical scheme of rocking bar with battery, but when using if during stop-spraying, need hand to touch after one's death the staving switch power supply turned off, use inconvenient; Its battery charging circuit does not have over-charge protective and overdischarge protector in addition, and battery is short service life, sprinkling expense height.
Summary of the invention:
The purpose of this utility model provides a kind of as long as operate the just sprayer of energy automatic switch electric water pump of spray boom switch, and its battery long service life.
The utility model power spraye, comprise spray boom, there is a dividing plate to be divided into the storage spray tank on top and the cabinet of bottom in the bucket in the staving, electric water pump is housed in the cabinet, battery is connected with electric water pump by control circuit, the electric water pump water inlet is communicated with at the bottom of the storage spray tank, it is characterized in that the three-way connection upper port is communicated with the electric water pump delivery port through check valve, left port is communicated with the reservoir pressure device, right output port is communicated with spray boom through outlet pipe, and wherein outlet pipe is equipped with the water-control switch that is connected with control circuit.
Water-control switch is made up of the outer tongue tube of magnetic float that is positioned at outlet pipe and pipe.
Control circuit is made up of battery charging circuit and water pump automatic control circuit, the charging control circuit that the parallel connection of battery two ends is made up of triode and relay polyphone in the charging circuit wherein, and transistor base is connected to voltage-stabiliser tube; In the water pump automatic control circuit, transistor collector is connected with relay, and magnetic switch is in parallel with the BG2 base stage, and the electric water pump power line is connected with relay switch.
The utility model is owing to set up check valve, threeway, reservoir pressure device and water-control switch; as long as the liquid flow in the spray boom; then open electric water pump automatically; liquid does not flow in the spray boom; then electric water pump is closed automatically, has reduced operational motion, the convenient use; and the anti-overcharge and over-discharge protection circuit of battery is arranged, battery obviously prolongs service life.
Description of drawings:
Fig. 1 is the utility model structure principle chart, and Fig. 2 is a water-control switch schematic diagram among Fig. 1, and Fig. 3 is control circuit figure.
The specific embodiment:
With reference to accompanying drawing 1, Fig. 2, the sprayer staving is divided into the fluid storage tank 1 on top and the cabinet 2 of bottom by the dividing plate 3 of making one, and the water inlet 4-1 of electric water pump 4 is communicated with at the bottom of the fluid storage tank.The delivery port 4-2 of electric water pump is communicated with the port 6-1 of three-way connection 6 through check valve 5, the port 6-3 of three-way connection 6 is communicated with reservoir pressure device 15, port 6-2 is communicated with spray boom 14 through outlet pipe 7, the stage casing of outlet pipe 7 wherein, one magnetic float 8-1 is housed in the pipe, this float is by one magnet of setting-in in the floating body material, and its proportion should be slightly larger than the proportion of water.The tongue tube 8-2 of pair of magnetic sensitivity is installed in the outer relevant position of outlet pipe 7 pipes.Battery 9, power switch 12, charging socket 11 also are housed in the cabinet 2, and their connection electric wire all is connected with control circuit 10.
With reference to Fig. 3, control circuit 10 is made up of charging road A and water pump control circuit B, battery E two ends and by relay J among the circuit A
1With the charging control circuit parallel connection that triode BG1 is connected into, relay switch J
2-1 one end is connected with charging socket 11, and its normal-closed end is connected with battery E is anodal, and the BG1 base stage is connected in series a voltage-stabiliser tube DW3 and and J
1-1 normal the battle connects.Triode BG2 collector connecting relay J among the circuit B
2, base stage, emitter stage tongue tube 8-2 in parallel two ends.
Operation principle:
When spray boom switch 13 cut out, water did not flow in outlet pipe 7 pipe, and magnetic float 8-1 sinks to bottom and tongue tube 8-2 relevant position because of deadweight, and tongue tube 8-2 connects, and the BG2 base voltage is zero, BG2 by and make relay switch J
2-1 is in the e point, and electric water pump 4 is not worked.When spray boom switch 13 was opened, the hydraulic pressure in the reservoir pressure device 15 made current spray from spray boom 14 through outlet pipe 7, and current are gone up the top away from tongue tube 8-2 position with float 8-1 simultaneously, tongue tube 8-2 disconnects, through voltage-stabiliser tube DW2, BG2 base stage G point produces voltage and makes the BG2 conducting, relay J
2Adhesive, J
2-1 connects with f point, electric water pump 4 electric and work, kept spray boom and continued to spray water.When water pump 4 was started working, the water in the reservoir pressure device 15 was replenished, and provided the initial flow play when spraying so that open next time.The pressurize of reservoir pressure device 15 when check valve 5 is used to shut down prevents that aqueous reflux is to water pump 4.
After work a period of time, battery E voltage drops to rated operational voltage when following, and voltage-stabiliser tube DW3 ends, and BG1 ends, and relay switch J1-1 connects a point, begins battery E is charged, and prevents the battery over-discharge.When cell voltage rises to upper voltage limit, DW3, BG1 conducting, relay J
1Action, J
1-1 adhesive is to the b point, and charging stops automatically, has prevented to overcharge the harm to battery.Switch 12 is used for the power supply control of operation during the whole story.
