Abstract
Method and apparatus for agricultural or horticultural spraying is based upon the cartridge system disclosed in GB 2304060A in which the concentrate medium is dispensed by a plunger into a flow of extender medium or dilutant at a rate controlled by a constant speed drive to the piston. This system is modified by eliminating the need for a supply of cartridges of differing cross-sectional sizes (to provide differing rates of application of medium to the crop) by using the cartridge/plunger assembly as a volumetric control means for at least one step in a preliminary or primary dilution or extension step in which the concentrate as supplied by the manufacturer is partially diluted or extended so that when the main dilution or extension step occurs, the required final concentration will be achieved.
Description
The present invention relates to be used for the spraying system of agricultural and gardening, with the method and apparatus that installs corresponding spray method and be used for the treatment technology problem, owing to the chemical material that in spray method and device, needs to provide diluted or other processing material, thereby these technical problems have been produced.These chemical materials or other are handled material and are existed with the form that highly concentrates, and have toxicity and/or dangerous and/or to the potential hazard of environment, therefore need handle very carefully and operate.In the system of former use, the operator of agricultural sprayer unit carries out dilution by conventional methods, this usual manner is manual dilution basically, relate to water pipe, bucket and the relevant dilution instrument of making, this previously used system is can not be received fully in labour law, especially aspect health and safety.
Carry out batch-type dilution (being attended by above-mentioned danger) for fear of needs, people have proposed to utilize the suggestion of dynamic process, in this dynamic process, measure a certain amount of concentrated solution, join in corresponding a certain amount of weak solution, needing to obtain the hydrojet agent of concentration.This method has following advantage, and it can provide the liquid of desired concn with the form of jar or tube, and jar or tube are connected on the sprayer unit with the form of seal, need not the concentration with any direct mode treat liquid (even solid).This system is disclosed among the WO92/11759 (Prolion) and other places.
But, although this system has solved safety issue by using the concentration medium, but adopt this method that a direct consequence is arranged, promptly need to change the concentration level of this concentration medium, so that divide the different stages correctly to spray with different amounts in its length of life.Therefore, according to top just concentrated solution quantitatively need being joined in the thinner of mentioning.This just need install one and measure mechanism in agricultural or horticultural machinery, this mechanism can change and measure out very little concentration (with very big rate of change) exactly, and service life is than the long service life of above-mentioned mechanical device.The so just little simple and durable degree of with the acceptable expense such device being installed easily and operating satisfies the needs of agricultural and gardening again.
Among application GB23 04 060A (referring to P53292GB) that before we are own, publishes, we have proposed a way that addresses this problem, but feasible need not of this method carried out in the mechanism accurately and the driving (comprising the variation of quite big speed) of pace of change in such measuring.By adopting a concentration cartridge system to reach this purpose, in this system with the piston of constant speed drive tube, by adopting the long-pending tube of varying cross-section to realize the difference of desired apportionment ratio.Yet such system needs to use and the corresponding concentration tube of institute's dilution rate that requires inevitably, and at least temporarily also is not easy the concentration tube that provides such.
Therefore, the objective of the invention is to seek to provide a kind of dilution and spraying system, this system kept GB 060A system the safety that should have and the advantage of accuracy, in order to satisfy concentration tube in the agricultural/horticultural (it is long-pending to have varying cross-section) can produce significantly different dilution rate when driving (piston of tube) with substantially constant speed these needs, relevant apparatus is improved simultaneously.
For agricultural of the present invention and gardening aspect and in the specialized application of the technical problem that is produced aspect this, at this in order to reach disclosed purpose, reference at large and the whole technology contents that merge the PCT application of publishing before us, the former PCT that publishes applies for as follows:
A) our reel number: P52821WO of WO97/16257
B) our reel number: P51958WO of WO94/11228
C) our reel number: P51794WO of WO93/02552
According to the invention provides a kind of as agricultural defined in the appended claims and/or gardening sprayer unit and method.
In U.S. Pat 5,409, a kind of semiconductor processor liquid spray systems that adds mixture that has is disclosed among 310 (Semitool).This system is used for the additive that thicks liquid is diluted in the main liquid in flowing.Dense additive is stored in the storage tube and by measuring pump and transfers in the mixing drum that drains.In mixing drum, add a certain amount of thinner and obtain diluted additive.Primary fluid stream is through a plurality of suction syringes, and each suction syringe has a suction inlet that absorbs liquid from mixing drum.This is a two stage dilution, and this process can easily be carried out the dilution of different dilution rates to additive.
System described in the embodiment of U.S. Pat 310, though this system provides a kind of device of accurate dilution, but itself with regard to semiconductor fabrication processes, this system is not suitable for using in agricultural or gardening spraying system, because this system has used a plurality of suction syringes (40) (rather than piston/cartridge of constant rate of speed), in order to produce needed dynamic dilution, each suction syringe is by the mobile driving of main fluid.In the semiconductor factory of similar laboratory condition Comparatively speaking, such structure may be able to be used with being entirely satisfactory, but be inapplicable fully under the operating condition of farm machinery, valid function under the unfavorable conditions such as farm machinery is need be when unclean, outside have water to exist and use more careless, thereby need reliable fully and simple.
In an embodiment of the present invention, important feature is exactly the use about the piston-type distributor, this distributor be used for effectively will the part dilution concentrated solution dynamic assignment (if necessary) to main fluid.Yet, a cell is arranged on the main part of piston-type distributor in one embodiment, in this cell, concentrated solution is carried out part dilution in advance with any required relative mixture.
By adopting the cartridge type distributor, this distributor has a piston-type driver, reliability and simplicity when perhaps other suitable machinery, various embodiments of the present invention have realized all that the needed agricultural/horticultural of technology/commercial field uses, the present invention uses in these fields just.In order to reach the accuracy of needed apportionment ratio control, be fit to very much adopt cartridge system with linear correlation mobile piston, this cartridge system is with a simple driver operated piston, and piston (or suitable machinery) system can provide the function (resemble agricultural and gardening and use needed reliability and simplicity) of a plurality of application needs.These functions comprise: the reverse drive piston sucks thinner and concentrated solution; Perhaps sequentially or at least be that part is side by side with thinner and concentrated solution mixing, the perhaps hybrid motion of passing through suction process and/or producing subsequently; With for the variation that cooperates hauling speed/ground speed and some part that needs to stop to spray crop once in a while, the variation to a certain degree of piston actuated speed, such as the furrow head in spraying the field and first and last a road time, do not need to use the overall with of sprayer.
In the back on the one hand, being interpreted as adopting the cartridge type piston system is the big variation that can not cooperate needed concentration in the agricultural/horticultural spray operation by changing driven plunger speed only, because this need accurately drive in very big speed range, however, the rate variation of some associative modes can be made us accurately providing with accepting by such system, and these change when the processing pulling speed changes spray rate variation of caused ground and other factors (crop width) is essential.
Like this, in a most preferred embodiment of the present invention as shown in Figure 5, spraying system of the present invention provides a kind of method and apparatus, this method and apparatus is difficulty own intrinsic and that exist for a long time in the time of can handling agricultural/horticultural aspect use concentrated solution, using concentrated solution in agricultural/horticultural is a kind of direct and simple and reliable mode fully, and this mode makes the user need not to touch by any way the harm that these concentrated solutions cause.The concentrated solution tube of a sealing is provided for spraying mechanical or device, the connected system that uses everybody to be familiar with can be connected to the sealing tube on the conduit of sprayer device at an easy rate, so just need not the user and touches concentrated solution from the external world.The concentrated solution tube is the container that transports thing such as beer commonly used in the brewery industry, and such as the polypropylene tube, the carrier pipe of concentrated solution tube (in this is used) also has its its feature, after being tightly connected, is at carrier pipe that sealing is opened in the connection procedure.The concentrated solution tube is connected on tube or other transfer element, and the latter links to each other with actuator piston, and actuator piston can be with limited rate variation.
Valve in this systematic conduit can produce the piston motion of a series of tube, thereby in tube, add volume required concentrated solution, add the thinner of determining volume then, thereby the concentration that makes concentrated solution produces corresponding small reduction, and the concentrated solution after will diluting a little then is distributed in the main spraying liquid.
Embodiments of the invention have kept the simplicity in the practicality of GB060A system and the accuracy of distribution, and the present invention adopts a piston-type injector or distributor to finish the core work of dense processing product distribution in thinner or the dispersant fluid.Each embodiment also provides the method (specification of GB060A) of the commutative tube that changes cross-sectional area, this variation pattern makes the user under the situation of using concentrated solution, concentrated solution dynamically with normally liquid dispersant and mixing diluents, at this moment will produce the apportionment ratio suitable with the tube effect only needs the operation of the driven plunger of a short series, to produce a pre-dispersed or dilution step, then be second or the dynamic dispersion or the dilution step (this step obtains the apportionment ratio of expectation) of order, obtain the flow velocity (can adopt in such a way) that this rate variation need not to change dispersant or thinner in place convenient or expectation.
Just can effectively control the thinner of diluted medium or the volume of dispersant (but may occur certain processing raw material of specifying crop in some cases without any need for the situation of disperseing or diluting) by the control main piston like this, up to the present the user can obtain needed cylinder/piston device of sizing.
Certainly, the person skilled in the art can see obviously that the batch dilution of dilution can carry out multiple variation.In principle, this system only needs to provide control system, and this control system makes actuator piston can control the filler motion of volume, not only in main assign action, and in advance in batches in the dispersion/dilution step.
May expect to use piston to control from give barrel in some cases and absorb concentrated solution, so just the liquid of known volume can be drawn in tube or the cylinder (or entering a medial compartment).Then this step is carried out next step (or truly having next step), and this next step be that a certain amount of thinner or the dispersant that capacity is controlled put into system.Piston and tube/cylinder device make the user to carry out volume controlled to batch dispersion or dilution step, even the volume of needed dispersant/thinner is zero under the situation once in a while.
Except under the control of piston, relatively directly concentrated solution being joined in the thinner (otherwise or) this method, those of skill in the art have following selection under specific service condition: such as, container by a sealing provides known volume and the fixing concentrated solution of volume to piston, airtight container is placed by hand by the user, under the remote control of system, open or disconnect, use piston to add thinner/dispersant then.The backward of this process is feasible in some cases, and in these cases, system can use the thinner/dispersant of fixed volume, is added the concentrated solution of amount of calculation volume by piston.
When the user will use the processing raw material (such as graininess) of solid state, this can be undertaken by piston system, this system can craft or remote control ground add the solid state medium of graininess or dispersity, this system cooperates agitating device to make solid dielectric remain on good dispersity in the different phase of use.
The control system of this device piston is preferably installed a data input and system's selecting arrangement, and data input device relates to reality (definitely) concentration of desired dilution process speed and operable processing raw material, and no matter it is in liquid state or solid state.Needed other data of this system comprise the volume flow rate fixing or that select of master dilution agent or dispersant and the 2-D data that relates to piston and Linear Driving speed thereof.
Disperse or dilution stage about second of dynamic and non-batch, those of skill in the art can appreciate the principle that the present invention is applied to this system very much, and it is the final mask of second dilution stage.Correspondingly, though dilution may be a useful method more for many using liquids, on-liquid disperses or is diluted in many other application that its value is also arranged, therefore we use the application WO97/16257 that also incorporates us into present this purpose (our reel number: in whole open explanation P52821WO), this application relates to use the dispersant of air as the agricultural/horticultural spraying system.Under these circumstances, output in tube of the present invention or the piston apparatus can dynamically mix with the liquid dispersed agent as described in above-mentioned patent specification, deliver to then in the chamber that forms droplet, perhaps before entering droplet formation chamber, (this is to minimize for the volume that makes conduit and cell to nozzle to nozzle landform resulting mixture, because when using different processing raw materials, need irrigating catheter and cell).One may be exactly be provided to droplet with " concentrated solution " of slightly diluted and forms the chamber from tube or piston apparatus again, at this moment has only air as second dispersant.
In following one embodiment of the present of invention, a kind of agricultural and/or gardening spray method, device and system are provided, the desired use speed of spraying processing raw material is finished by a dynamic blend step in this system, and this dynamic blend step is that concentrated solution is entered into liquid dispersed agent or thinner.Concentrated solution is distributed to speed in the thinner by a driver control with (relatively) constant rate of speed running, and the piston of this driver control tube or similar means makes it disperse concentrated solution with constant speed.In order to cooperate concentrated solution to be distributed to the needs of liquid dispersed agent or thinner rate variation, a kind of system is provided, this system can obtain the effect of the long-pending tube of varying cross-section in the specification of GB060A.(in GB060A) this result is achieved by alternative, but by adopting piston to change the ejection concentration of concentrated solution, the Cmax that is sprayed is exactly the strong solution concentration that the manufacturer produces.Provide one before piston or tube mechanism dispersion concentrated solution concentrated solution to be carried out prediluted system for this purpose, this piston or tube mechanism are with constant speed driven plunger.
By dilution in two stages is provided, just obtained needed flexibility and simplicity in the operation of agricultural and gardening, the phase I rate-compatible, second stage speed relative fixed, and in this dynamic mixed process, kept necessary accuracy, and need not to use the drive unit of complicated variable bit rate and other may cause reliability low, use complicated and expensive system.
In order to reach prediluted purpose, liquid dispersed agent or thinner, concentrated solution and mixer are provided, in mixer, a kind of liquid is joined in the another kind of liquid, and a capacity control device (can comprise piston apparatus), can produce Volume Changes in the pre-dilution by this device.
Need not operator's direct intervention (referring to craft) in order to carry out necessary pre-dilution, volume change mechanism (can be made up of piston apparatus) is carried out remote control.Provide by the device of remote control, in second (relatively) fixed rate dilution step, add the thinner of requirement, thereby obtain having the spray of required ultimate density.
Fluid by above-mentioned two stages disperses and dilution, and second dilution step of (relatively) fixed rate can carry out accurately and simply controlling, and has kept the advantage of the intrinsic safety of dynamic dispersion and dilution simultaneously.
First dispersion or dilution step have the advantage that can carry out desired variable step in dilution, (using and installing corresponding to different size tube among the GB060A).In dilution, use resulting concentrated solution in the mode of batch or control, such as from tube.This mode can be adopted in the following method: the thinner of Volume Changes (but less relatively) is joined that volume is determined or even fixing original (the denseest) concentrated solution in.Like this, this method and apparatus just allows the volume according to needed final concentrated solution in the spraying medium, and the thinner of desired (less relatively) volume is joined in the concentrated solution (known volume is fixed), and the amount of concentrated solution can change.One purpose needed definite volume in back can very easily obtain by a simple contrast list.Under the situation of remote control, carry out the device of dilution so on a small scale, can obtain (being preferably main dispensing piston) by a simple piston-type mechanism, this piston-type mechanism has remote (with an automatically) operation exchange valve mechanism, this mechanism can bleed off volume required thinner, be sent to then the tube or other contain in the container of concentrated solution, agitator mixes fully then.
Adopt the cartridge type capacity control device can accurately control volume ratio in the dilution step in advance.Those skilled in the art can design other structure.Yet this hardware system is practical, can satisfy agricultural/horticultural user's needs well.Like this, a common structure comprises: a main tube that holds thinner, thinner is fresh water normally, second of holding spraying medium concentrated solution, this tube is more much smaller than main tube, capacity dilution control device and an excretion device of tube and piston-type, this chamber has the actuator piston of a relative constant rate of speed, concentrated solution and thinner that capacity system will be reserved volume in advance mix in this chamber, from the nozzle of sprayer unit before the ejection, the liquid of constant rate of speed driver after with premixed dynamically mixes with the thinner main fluid final.
In a special simple embodiment of the present invention, do not need to provide container separately, no matter be in order to supply with concentrated solution, still for concentrated solution and mixing diluents, or in order to be distributed in the master dilution agent with the concentrated solution of constant dispersion rate after with slightly diluted.These functions can realize by the concentrated solution tube (volume is known) that is installed in when spray operation begins on the sprayer.The concentrated solution tube has enough volumes to be used for adding the thinner of (less relatively), produces a uniform slightly diluted concentrated solution by simple internal mix mechanism.And the concentrated solution tube itself is easy to install a constant rate of speed actuator piston that is used for dispense liquid.
Among the described below embodiment, can realize needed dilution flexibility by first and second dilution step, the technical complexity that does not have simultaneously variation continuously and high accuracy system again, this continuous variation is used for continuously very small amount of concentrated solution being distributed to relative a large amount of thinner with the system of high accuracy.By adopting this straightforward procedure that drives in the second dilution step constant rate of speed, thus the structure of this step and operation reasonable price, simple, effectively, accurately, reliable.
Change first dilution step separately into by the dispersion or the dilution step that will change, the effective ways that just provide a kind of simple and cheap variation to spray the final thinner of medium.This is because can carry out the batch dilution step, such as, join in the thinner of same relatively small amount by the concentrated solution of simple relatively piston-type device accurately relatively small amount, because simplicity and relative accuracy that this device is intrinsic, this first dilution step has satisfied above-mentioned performance standard.
