Abstract

An automatic control pesticide spray machine comprises a motor, a hydraulic pump, a pesticide container and a pesticide liquor suction pipe that are all positioned in one position, as well as a hand-operated switch and a spray rod that are remotely operated via a connected hose. The pesticide spray machine is characterized in that a pressure sensor is fixed outside a pump body of the hydraulic pump, a hydraulic passage is communicated with a hydraulic cavity of the pump body, and the output terminal of an electrical signal is connected with a switch controller connected in a power supply circuit of the motor. The hydraulic pump adopts a roto-jet pump or an injection pump to solve the problems in the prior remote operated pesticide spray machine that the energy consumption of race rotation of the motor is high and the pipe breaking is generated due to the rise of hydraulic pressure, thereby saving electric energy by about one third. The pesticide spray machine has the advantages of convenient control and low cost, reduces operating staff, and can be widely used for spraying pesticide in remote operation in the field of vegetable bases, fruit bases, fruit grower, gardening and the like.

Description

Automatically control vehicle-mounted sprayer

(1) technical field:

The utility model relates to a kind of vehicle-mounted sprayer, belongs to the equipment class (A01M) that the kill harmful animal and plant is used.

(2) background technology:

The existing ground such as orchard that is used for is by following formation of the remote-operated vehicle-mounted sprayer of operator: see Fig. 1,1. the hydraulic pump 4 that drives of electromotor 1 and its; 2. medicine container 6 and the soup suction tube 5 that is connected medicine container and hydraulic pump arrival end; This two large divisions all need be placed in the house fixing in the ground such as orchard, and hand switch 8 and spray gun 9 then pull in the orcharding of distant place by the flexible pipe 7 that is connected with the hydraulic pump port of export and spray insecticide.Existing vehicle-mounted sprayer, the operator is in the house behind actuating motor and the hydraulic pump, open hand switch 8 and spray gun 9 carries out pesticide spraying in the operation of long-range place then, general 200～500 meters of long-range place distance, having sprayed to change when this a slice then needs to close hand switch and spray gun when spray at another place, but electromotor and hydraulic pump in the room, distant place this moment also can not get closing, and hydraulic pressure rises gradually in hydraulic pump and the flexible pipe to making, and usually produce booster thus and cause motor idle running power consumption greatly.In order to prevent booster etc., after closing hand switch, adopt the cry mode allow at a distance personnel close motor power in the room sometimes, but, can not deal with problems at all apart from too far away not hearing.

(3) summary of the invention:

The automatic control vehicle-mounted sprayer that the utility model provides solves in the existing operated from a distance vehicle-mounted sprayer exactly, waste of energy and because of hydraulic pressure raise to produce the problem of booster, and its technical scheme is as follows:

Automatically the control vehicle-mounted sprayer comprises the electromotor 1, hydraulic pump 4, medicine container 6, the soup suction tube 5 that are placed on a place; And carry out hand switch 8 and the spray gun 9 that operated from a distance is used by the flexible pipe 7 that connects, it is characterized in that:

Fix a pressure sensor 3 outside the pump housing 4.1 of hydraulic pump 4, hydraulic channel is communicated with hydraulic cavities in the hydraulic pump body 4.1 in the pressure sensor, and pressure sensor 3 electrical signals connect on-off controller 10, and on-off controller inserts electric electromechanics source circuit 1.1.Above-mentioned hydraulic pump is to adopt rotary-jet pump or syringe pump 4.

The utility model beneficial effect:

I. this patent design principle is according to required operating pressure, by the opening and closing of sensor electrical signal automatic remote control motor, efficiently solves the big problem of motor idle running power consumption, but saves energy about 1/3.Ii. pressure reaches higher limit.Automatically disable motor effectively prevents the booster generation that pressure raises and causes.As long as iii. open or close hand switch, just but pressure changes the automatic control motor opening and closing, and Long-distance Control is convenient, reduces operating personnel.Iv. automaton is simple, and cost is low.V. can be widely used in the operated from a distance pesticide spraying in fields such as vegetables base, fruit base, orchard worker and gardening.

(5) embodiment:

Present embodiment is controlled the following formation of vehicle-mounted sprayer automatically:

See Fig. 1, see Fig. 2, hydraulic pump 4 adopts rotary-jet pumps, and rotary-jet pump 4 includes the shell pump housing 4.1, rotating shaft 4.4, impeller 4.5, the suction inlet 4.2 that is communicated with soup suction tube 5, the ejiction opening 4.3 that is communicated with flexible pipe 7.Electromotor 1 output is in transmission connection by rotating shaft 4.4 and rotary-jet pump.Medicine container 6 is communicated with rotary-jet pump by soup suction tube 5 and suction inlet 4.2.Flexible pipe 7 far-ends dress hand switch 8 and spray gun 9.See Fig. 2, outside the pump housing 4.1 manometer 2 can be installed simultaneously, can monitor hydraulic pressure in the pump housing simultaneously.

See Fig. 1, see Fig. 2, fix a pressure sensor 3 outside the pump housing 4.1 of rotary-jet pump 4, pressure sensor adopts diaphragm type pressure sensor 3, and hydraulic channel is communicated with hydraulic cavities in the pump housing 4.1 in it.Diaphragm type pressure sensor is to utilize the interior hydraulic channel pressure of sensor to change to make the diaphragm change in location and connect circuit, belongs to the mechanical compression sensor, for selling product in the existing market.See Fig. 3, pressure sensor 3 electrical signals connect on-off controller 10, and on-off controller 10 inserts in the electric electromechanics source circuit 1.1.Present embodiment on-off controller 10 can adopt A.C. contactor 10.

See Fig. 3, Fig. 2, the course of work: electromotor 1 starts by 4.4 rotations of rotating shaft 4.5 impeller, rotary-jet pump 4 sucks soup by suction tube 5 suction inlets 4.2 from medicine container 6, in rotary-jet pump, form pressure, hand switch 8 is at a distance opened, soup through rotary-jet pump ejiction opening 4.3, flexible pipe 7, by spray gun 9 ejections, sprays under pressure at last.When having sprayed orchard, a place, need close hand switch 8, this moment, rotary-jet pump 4 and flexible pipe internal pressure rose, when pressure reaches in limited time, pressure sensor 3 outputs send the signal of telecommunication and are input to on-off controller 10, and instruction control motor power 1.1 circuit disconnect, and motor has a power failure and cuts out.Pressure reaches down in limited time in spraying, and pressure sensor 3 outputs send the signal of telecommunication and are input to on-off controller 10, and instruction control motor power 1.1 circuit are opened.Realize automatic control with this.
