Description
Technical field
The utility model is the test unit, the particularly structure-improved of the installation of spraying machine nozzle component, test unit that a kind of agriculture medical instruments are used the spraying machine parts.
Background technology
The agricultural medical instruments in shower nozzle testing table and mist amount distribution tests instrument, laser grain spectrometer, camera and the supporting use of electronic scales, can be measured even that shower nozzle mist amount distributes, parameters such as fogdrop diameter, spreading of spray and flow with shower nozzle.
The agricultural medical instruments have polytype with shower nozzle, fan nozzle, solid cone shaped nozzle, conical hollow nozzle, impinging injector and anti-drift nozzle etc., the short crop of pair wheat is arranged, pair Chinese sorghum, corn long-stalked crop are arranged, have pair spraying operation of branch higher object to use.In order to simulate actual use state, shower nozzle is tested at testing table, often needs to regulate certain height, and, wish that lifting has the certain height scope.But, nowadays domestic and international, all be that screw hole is regulated height in the art, namely enable lifting, its scope also is very little, so test unit, for make, test, one type of monitoring, fixedly the shower nozzle problem of model is little, still can use, but for some special mechanism for testing, use very difficult, must be equipped with the proving installation of multiple differing heights, specification, cause the test site floor area big, change, transfer trouble back and forth, waste of manpower, material resources and time.At present, in order to strengthen the quality monitoring to market, manufacturing enterprise, improve technical merit and the quality in whole spraying field, government, industry will strengthen check and sampling observation, not have corresponding testing apparatus, will have a strong impact on monitoring, test job implementation.
In detecting process of the test, shower nozzle must be constant in force value, reach under the standard value state and test, Teat pipette must could force value stablized after a period of time after the startup, and another problem that prior art exists is, for this reason, after Teat pipette started, test person must be lifted with basin or bottle, was placed on the shower nozzle below, wait for vessel such as the stable recession of force value following bottle, tin, be transformed into the normal condition test.So operation is very inconvenient, and when the shower nozzle mounting bracket of testing table was higher sometimes, the operator can not be easily, the specific aim area is contained the experimental liquid of force value shakiness in early stage, and experimental liquid is sprayed onto everywhere, influences the accuracy of test site and test.
More than two class problems, in the mechanism of special test, occasion, cause very big difficulty and trouble, hope can have improvement, improvement behave.
The utility model content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, provide a kind of can easy of rise shower nozzle setting height(from bottom), can avoid trouble by the artificial long-pending shower nozzle test unit of containing transient pressure value experimental liquid in early stage.
The purpose of this utility model is realized by following technical scheme.
A kind of agriculture medical instruments test unit of shower nozzle is characterized in that:

The horizontal clamping spray boom on the top of described slide bar, one end of spray boom is connected to water tank through liquid pump, and the other end of spray boom connects the through hole in the four-way, and other three through holes of four-way connect respectively: tensimeter, normally open solenoid valve is back to water tank, and normally closed solenoid valve is connected to the test shower nozzle.
Adopt the technical program, when rotating rotary handle, rotary handle rotates with the screw thread ring set, and external thread matches on the internal thread of screw thread ring set inwall and the slide bar, because slide bar one side is offered the elongated slot parallel with axis, screw in anti-turn screw at the supporting sleeve tube wall, embed in the elongated slot of slide bar, so slide bar can not rotate with the screw thread ring set, can only in sleeve pipe, move up and down, sleeve pipe is fixed on the movable stand, and the frame so slide bar can only relatively move also is that relative ground moves up and down.According to operating personnel's requirement, rotate rotary handle, can realize easily that slide bar is elevated to the height that appointment needs, ejecting device is on spray boom, and spray boom is installed in the top of slide bar, so shower nozzle can be on demand, oscilaltion indiscriminately ad. as one wishes.
Another feature of the technical program, one end of spray boom is connected to water tank through liquid pump, the other end of spray boom connects four-way, and before official testing, still the water of unsettled force value is back to water tank by normally open solenoid valve, when tensimeter shows to normal pressure value, switching solenoid valve is closed normally open solenoid valve, opens normally closed solenoid valve, tensimeter flows out from normally closed solenoid valve, shower nozzle, can be formally, proper testing.
Further, be embedded in the rectangle feather key that can move up and down along elongated slot at the elongated slot of described slide bar, described anti-turn screw stretches into feather key, and the termination of anti-turn screw is against the bottom land of slide bar elongated slot through ball.
Further, fix a supporting plate that is level in the welding of the top of described slide bar, above supporting plate, be the pressing plate clamping spray boom of Ω shape, be connected and fixed by the both sides bolt.
Further, the external thread of described slide bar upper semisection accounts for 2/3 of total length.
Further, described rotary handle center is circular hole, is nested with in the outer ring on threaded collar cover top, and both are tightened together by the lock-screw of sidepiece.
Further, rotary handle is driven by numerical-control motor.
The beneficial effects of the utility model, 1. the utility model apparatus structure is simple, and reliable in action is easy to operate; 2. the utility model can make things convenient for, at random adjust, change the height of shower nozzle, adapts to the test of different size, model shower nozzle, and a bench teat experiment device can serve as multiple different model testing table usefulness, economy, and convenience, operability improves, the place compactness; 3. need not improve operation convenience long-pending being filled with water in test early stage, laborsaving, also avoid the ponding pouring, avoid spill during ponding early stage, the trouble action of avoiding highly higher test board to climb up climbing down.4. rotary handle can be realized electronic, automatic control more easily as by motor-driven.Shower nozzle mechanism for testing to specialty has great application value.
