Description
Technical field
The utility model relates to a kind of agricultural machinery accessory be applied in plant protection art.
Background technology
For spraying the pattern that the agricultural machinery of plant protection product is all the medicine storing pot cooperation air compressor machine adopted in existing agricultural machinery; the tracheae communicated with air compressor machine with one in shower nozzle; and a drug delivery pipeline communicated with medicine storing pot; an atomising head is set at spray outlet place, then by the pressure of gas, medicament is atomized rear spouting.But after being through application for a long time, find that the shower nozzle of this routine exists following problem: one, during medicament thickness, the effect of atomized spray is bad, and Chang Rongyi blocks shower nozzle.Two, when the area needing to spray is less, the output pharmaceutical quantities not by adjusting medicine storing pot adjusts spray amount, causes local concentration too high.
Summary of the invention
In order to solve the technical problem mentioned in background technology; the utility model provides a kind of operation head on plant protection product spraying machine, and this kind of operation head when medicament thickness, can carry out viscosity reduction to medicament; to guarantee jeting effect, the automatic adjustment to exporting pharmaceutical quantities can also be realized simultaneously.
The technical solution of the utility model is: the operation head of this kind on plant protection product spraying machine, comprise the triple-valve body that has liquid flow inlet pipe, its unique distinction is: the upper end of triple-valve body is threaded connection valve rod pressure cap, and the lower end of triple-valve body is threaded connection tee-joint sleeve; Lower 1/3 place in triple-valve body forms two-stage eddy flow chamber after being connected by little cylinder transition with the second circular cone baffle plate by the first circular cone baffle plate;
Above the first circular cone baffle plate, be fixed with fixed valve plug by step surface, between fixed valve plug and the inner core of triple-valve body, realize sealing by sealing ring; Fixed valve plug has the opening excessively that some diameters change successively, the described some first hole heart crossing opening is positioned on same circular path; Coaxial chimeric movable valve plug on fixed valve plug, the central authorities of movable valve plug have the valve rod square post jack of rectangle, movable valve plug is positioned at and has one circular second outside valve rod square post jack and cross opening, the circular path that the second axis crossing opening is formed after the axis rotation of movable valve plug is identical with the circular path that the hole heart of described some first mistake openings is formed; The bottom of fixed valve plug has pin hole, inserts for the spool safetied pin running through triple-valve body;
Described operation head also comprises valve rod and stepper motor; The bottom of valve rod is square post, and described square post matches with valve rod square post jack; The middle part of valve rod has the boss of reducing, and the part on boss is cylinder, and the barrel portion of valve rod is coaxially connected with stepper motor by shaft coupling through after the axis hole of valve rod pressure cap central authorities; Stepper motor is vertical to be fixed on electric machine support, and electric machine support is fixed on valve rod pressure cap by stone bolt;
The left end of tee-joint sleeve is welded with flange, and gas flow tube is fixed in flange, and the port of export of gas flow tube is the cone structure shunk, and the port of export of gas flow tube is positioned at below the vertical outlet in triple-valve body two-stage eddy flow chamber; The right-hand member of tee-joint sleeve is threaded connection the atomising head being equipped with screen cloth, and atomising head and gas flow tube have identical central axis.
The utility model has following beneficial effect: the agricultural machinery shower nozzle that this kind of operation head can directly substitute for spraying plant protection product uses; when agent viscosity is suitable; during without the need to reducing agent viscosity, the stepper motor of this kind of operation head does not start, and its effect is quite just a common shower nozzle.When needs reduce agent viscosity, start stepper motor, it is made to rotate continuously, the flowing hole of the movable valve plug flowing hole different from the some radiuses on fixed valve plug sequentially communicates, after liquid medicine flows through movable valve plug and fixed valve plug, because area of passage reduces gradually, flow velocity can increase suddenly, shearing and collision effect can be created to liquid medicine thus, its viscosity is declined.Subsequently when after liquid medicine pass-out fixed valve plug, under the effect of circular cone baffle plate, in secondary eddy flow chamber, create strong eddy current, thus medicament is sheared again smash.When needing the pharmaceutical quantities adjusting medicine storing pot output, Long-distance Control stepping motor drives movable valve plug to turn to suitable flowing hole, just can complete.
