When the motor 2 operates, the eccentric wheel 30 can rotate along with the output shaft of the motor 2, when the eccentric wheel 30 rotates, the eccentric wheel 30 can be intermittently contacted with the second air bag 29 and extrudes the second air bag 29, the air flow is limited by the second one-way valve on the second hose at the upper end and can only flow into the second air bag 29 from the outside, the air flow is limited by the second one-way valve on the second hose at the lower end and can only flow out of the second air bag 29, so that along with the intermittent contraction of the second air bag 29, the second air bag 29 can continuously pump the air into the first air bag 27, when the first air bag 27 is filled with the air, the air can flow out of the air outlet pipe, and the first air bag 27 can be always in an inflation and expansion state by the second pressure valve arranged in the air outlet pipe.
First gasbag 27 can drive depression bar 26 when taking place to expand and remove left, and make depression bar 26 extrusion piezo-resistor 25, piezo-resistor 25 is a resistance device with nonlinear volt-ampere characteristic, when piezo-resistor 25 receives certain mechanical external force, its resistance can reduce, therefore, when the depression bar 26 tightly supports piezo-resistor 25, piezo-resistor 25's resistance can reduce, make piezo-resistor 25, the closed loop total resistance that electromagnetic plate 34 and external power supply formed jointly reduces, according to series circuit ohm law: i = U/R, total resistance in the series circuit reduces and makes total current increase in the circuit, thereby make the increase of current through electromagnetic plate 34, make electromagnetic plate 34 can circular telegram magnetism, electromagnetic plate 34 can attract baffle 33 and make baffle 33 remove right after getting magnetism, make the pesticide in pesticide case 4 can't continue to get into in the ration case 5 through connecting pipe 31, to sum up, motor 2 can make baffle 33 keep off connecting pipe 31 when running, the pesticide of guaranteeing to spray at every turn only has the quantity of the pesticide that holds in the ration case 5, thereby realize the ration and spray, prevent that the pesticide from spraying too much the condition.
Because the side wall of the movable plate 13 is attached to the inner wall of the control box 12, and the sections of the movable plate 13 and the control box 12 are both rectangular structures, the movable plate 13 can drive the second screw rod 15 to rotate when moving left and right, the second screw rod 15 can drive the transmission rod 17 to rotate through the two bevel gears 16 which are meshed with each other when rotating, and then the rotating rod 6 and the stirring blades 7 are driven to rotate through the synchronous belt.
Along with the pesticide in the dosing box 5 is consumed gradually, the liquid level that floats piece 18 can follow the pesticide descends gradually, after the pesticide in the dosing box 5 is consumed and finishes, float piece 18 can descend the bottom of dosing box 5, magnetic stripe 22 just right with the lower extreme in the magnetic path 19 in the float piece 18 this moment, lower extreme magnetic stripe 22 can drive first current conducting plate 21 and move left under the appeal of magnetic path 19, thereby make first current conducting plate 21 and second current conducting plate 23 alternate segregation, so motor 2 can cut off the power supply and stop the operation, until next time dosing box 5 is filled with the pesticide.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
