(54) Aggregat til reguleret udspredning af stoffer, såsom gødning eller in= sekticid, fra en landbrugsmaskine.(54) Aggregate for controlled dispersal of substances, such as fertilizers or insecticides, from an agricultural machine.

Opfindelsen angår et aggregat til reguleret udspredning af stoffer, såsom gødning eller insekticid,fra en landbrugsmaskine, og af den art, hvor det stof, der skal udspredes, løbende hentes fra en beholder under konstant tryk, og hvor et af maskinens hastighed afhængigt, elektrisk styresignal for spredningsmængden gennem en indstillelig deler ændres efter den ønskede spredningsmængde.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembly for controlled dispersal of substances, such as fertilizers or insecticides, from an agricultural machine, and of the kind in which the substance to be dispensed is continuously extracted from a container under constant pressure, control signal for the spread rate through an adjustable divider is changed according to the desired spread rate.

Ved landbrugsarbejdet, specielt når dyrkede områder skal besprøjtes med stoffer, er det nødvendigt at sørge for, at der sker en regelmæssig sprøjtning t— af en given mængde stof i væskeform pr. arealenhed.In agricultural work, especially when cultivated areas are to be sprayed with substances, it is necessary to ensure that a regular spraying of a given amount of liquid substance per day is necessary. unit area.

^ Et konstruktionsmæssigt ret kostbart aggregat af den indledningsvis nævnte art kendes fra beskrivelsen til US-patentskrift nr. 3.518.953, hvor aggregatet, ^ der er påmonteret en landbrugsmaskine, gennemstrømmes af udspredningsstoffet, hvilket kun giver en grov og langsom og ikke særlig stabil regulering. Deleren er * Ω 2 1ΑΛΛ01 udformet med drejeknap, der i praksis kun kan indstilles, når maskinen står stille.A constructionally quite expensive aggregate of the kind mentioned above is known from the description of US Patent No. 3,518,953, wherein the aggregate mounted on an agricultural machine is flowed through the spreading material, which gives only a coarse and slow and not very stable regulation. . The divider is * Ω 2 1ΑΛΛ01 designed with a knob that can only be adjusted when the machine is stationary.

Opfindelsen giver anvisning på et reguleringsaggregat, der på enklere måde sikrer en hurtigere og mere præcis regulering.The invention provides a control unit which in a simpler way ensures a faster and more precise regulation.

Med henblik herpå er et aggregat ifølge opfindelsen ejendommeligt ved, at overføringen af styreprocessen sker ad elektrisk vej, hvorved det hastighedsafhængige styresignal består af en tilsvarende varierende udgangsspænding, som deles ved hjælp af et potentiometer, og at den til den ønskede spredningsmængde svarende delspænding tilføres styreorganer, der omfatter en motor indrettet til at virke i afhængighed af nævnte delspænding.To this end, an assembly according to the invention is characterized in that the transmission of the control process is by electrical means, whereby the speed-dependent control signal consists of a correspondingly varying output voltage divided by a potentiometer and the control voltage corresponding to the desired spreading quantity is supplied to the control means. comprising a motor adapted to operate in dependence on said partial voltage.

Ved overføring af styreprocessen ad elektrisk vej er det på enkel måde gjort muligt at opnå en meget hurtig og præcis regulering af spredningsmængden.By transferring the control process by electrical means, it is easy to achieve a very fast and precise control of the amount of spread.

Hele det elektriske aggregat kan udformes som trykt kredsløb, der er nemt at håndtere og i tilfælde af svigt nemt kan udskiftes, uden at maskinen holdes ret længe i stå. Desuden kan aggregatet placeres inden for rækkevidden af maskinens fører, der således under kørslen uden videre kan foretage den fornødne ændring af spredningsmængden ved hjælp af deleren, der i henhold til opfindelsen udgøres af et potentiometer.The entire electrical unit can be designed as a printed circuit that is easy to handle and can easily be replaced in the event of failure without holding the machine for a long time. In addition, the unit can be placed within the range of the machine driver, which can thus easily make the necessary change of the spreading quantity during the run by means of the divider which according to the invention is constituted by a potentiometer.

Fra DE OS 1.534.029 kender man et arrangement, hvor en del af reguleringsprocessen foregår ad elektrisk vej . I dette kendte arrangement består det hastighedsafhængige styresignal af en på tilsvarende måde varierende udgangsspænding, der tilføres et styreelement med kobling og med en i afhængighed af spændingen virkende motor. I dette kendte arrangement sker ændringen af den af det hastighedsafhængige styresignal regulerede spredningsmængde og af den valgte spredningsmængde gennem en mekanisk aktiverbar glider således, at dette kendte arrangement faktisk udviser de samme ulemper som tidligere nævnt under henvisning til det førstnævnte patentskrift.DE OS 1.534.029 discloses an arrangement in which part of the regulation process takes place by electrical means. In this known arrangement, the speed dependent control signal consists of a correspondingly varying output voltage applied to a control element with coupling and with a motor acting in dependence on the voltage. In this known arrangement, the change in the amount of spread controlled by the speed-dependent control signal and of the selected amount of spread through a mechanically activatable slider takes place so that this known arrangement actually exhibits the same disadvantages as previously mentioned with reference to the former patent.

Opfindelsen forklares nærmere i det følgende under henvisning til den skematiske tegning, der viser et udførelseseksempel på apparatet ifølge opfindelsen.The invention will be explained in more detail below with reference to the schematic drawing showing an embodiment of the apparatus according to the invention.

Apparatet omfatter en hastighedsdetektor 1, der gennem et organ 2 til forindstilling af den givne størrelse er koblet til et reguleringsorgan 3.The apparatus comprises a speed detector 1 coupled through a means 2 for presetting the given size to a control means 3.

I det tilfælde, hvor reguleringsapparatet anvendes til regulering af en strømmængde fra en ventil i afhængighed af maskinens hastighed, er hastighedsdetektoren 1 forbundet med maskinens hjul. Reguleringsorganet 3 styrer en ventil, der regulerer den fra en forstøver afgivne mængde.In the case where the regulator is used to regulate a flow rate from a valve depending on the speed of the machine, the speed detector 1 is connected to the wheels of the machine. The regulator 3 controls a valve which regulates the amount delivered from a nebulizer.

Forindstillingsorganet 2 tjener til at indstille ventilens åbning i afhængighed af det produkt, der skal forstøves. Denne størrelse er kendt og den er uafhængig af maskinens funktion.Deme forindstilling af organet 2 overlejres pa den størrelse, der hidrører fra hastighedsdetektoren 1 og afhænger af maskinens 3 U4401 hastighed.The presetting means 2 serves to adjust the valve opening depending on the product to be atomized. This size is known and it is independent of the operation of the machine. The presetting of the member 2 is superimposed on the size resulting from the speed detector 1 and depends on the speed of the machine 3 U4401.

Detektoren 1 udgøres af en vekselstrømsgenerator A, der er koblet til maskinens hjul. Vekselspændingen tilføres en ensretterbro D1, hvorfra den ensrettede spænding føres til en udglatningskondensator C.The detector 1 consists of an alternating current generator A coupled to the wheels of the machine. The alternating voltage is applied to a rectifier bridge D1, from which the rectified voltage is fed to a smoothing capacitor C.

Det ensrettede signal, der opstår over udgangen fra detektoren 1, er proportionalt med hjulets bevægelse. Over modstanden RI føres signalet til for-indstillingsorganet 2. Dette organ udgøres af en modstand PI med udtag, som er tilsluttet en transistor TI. Positionen af udtaget på modstanden PI bestemmer styrespændingen til transistoren og indstilles ved hjælp af en ikke vist drejeknap. Denne indstilling foretages manuelt i afhængighed af den mængde produkt, der skal forstøves per arealenhed. Udgangen fra forindstillingsorganet 2 er forbundet med reguleringsorganet 3, der indbefatter en motor M til styring af det organ, der skal reguleres, f.eks. til åbning af en ventil, i afhængighed af det signal, der modtages fra detektoren 1, og på hvilket overlejres det signal, der hidrører fra forindstillingsorganet 2.The unidirectional signal generated over the output of the detector 1 is proportional to the motion of the wheel. Above the resistor R1, the signal is passed to the preset means 2. This means is constituted by a resistor P1 with outlets connected to a transistor T1. The position of the outlet on the resistor PI determines the control voltage of the transistor and is adjusted by means of a rotary knob not shown. This setting is done manually depending on the amount of product to be atomized per unit area. The output of the presetting means 2 is connected to the control means 3, which includes a motor M for controlling the means to be controlled, e.g. for opening a valve, depending on the signal received from the detector 1 and on which the signal originating from the preset 2 is superimposed.

Motoren M kan f.eks. være af den art, der har en stator med permanentmagneter og kan fødes gennem to elektriske kredsløb i afhængighed af drejeretnin-gen, dvs. i hvilken retning reguleringen skal finde sted.The motor M can e.g. be of the kind that has a stator with permanent magnets and can be fed through two electrical circuits depending on the direction of rotation, ie. in which direction the regulation should take place.

Det ene kredsløb omfatter en diode D^ og en modstand R2, som er tilsluttet basen i en transistor T3, hvis kollektor over en modstand R,. er tilsluttet basen i den første transistor i en Darlington-kreds T^, . Emitt'1- ren i den anden transistor er tilsluttet en diode D^, som er forbundet med motoren M. Dette kredsløb er dog kun strømførende, når tyristoren Th^ åbnes via modstanden R . Når dette er tilfældet, drejer motoren i den ene retning.One circuit comprises a diode D 1 and a resistor R2 connected to the base of a transistor T3, the collector of which is across a resistor R 1. is connected to the base of the first transistor of a Darlington circuit T ^ ,. The emitter of the second transistor is connected to a diode D ^ which is connected to the motor M. However, this circuit is only live when the thyristor Th ^ is opened via the resistor R. When this is the case, the motor turns in one direction.

\Jcl Når den modsvarende gren: D^, R^, T* , T'^, T1,., T2, Th- og R^ er strøm førende, drejer motoren i den anden retning.\ Jcl When the corresponding branch: D ^, R ^, T *, T '^, T1,., T2, Th- and R ^ are current-conducting, the motor turns in the other direction.

Strømtilførslen i den ene gren eller den anden gren styres fra transistoren T2, som forspændes normalt for at frembringe en kollektorspænding og en emitterspænding V2, hvilke spændinger ikke afviger ret meget fra spændingerne for Zener-dioderne D^ og D^j henholdsvis 9V og 3V, Kol lektormods tanden R og emittermodstanden R kan indstilles. Når basisstrømmen til transistoren c e T2 aftager, stiger spændingen og det kredsløb, der er tilsluttet Zener- dioden bliver strømførende, hvorved motoren sættes i gang. Hvis basisstrøm men til transistoren T2 vokser, stiger spændingen V2 og det kredsløb, der er tilsluttet Zener-dioden D^ bliver strømførende, hvorved motoren M aktiveres.The current supply in one branch or the other branch is controlled from the transistor T2, which is normally biased to produce a collector voltage and an emitter voltage V2, which voltages do not differ much from the voltages of the Zener diodes D1 and D1, respectively 9V and 3V, The carbon resistor tooth R and the emitter resistance R can be set. As the base current of the transistor c e T2 decreases, the voltage increases and the circuit connected to the Zener diode becomes energized, thereby activating the motor. If the base current but to the transistor T2 grows, the voltage V2 increases and the circuit connected to the Zener diode D ^ becomes live, thereby activating the motor M.

De enkelte komponenter i de to kredsløb er således valgt, at disse to kredsløb ikke kan være strømførende samtidig.The individual components of the two circuits are chosen so that these two circuits cannot be live at the same time.

Til ændring af basisstrømmen til transistoren T2 anvendes der en indstillelig modstand hvis udtag er mekanisk forbundet med motoren M, således at motoren altid aktiveres i retning mod ligevægtstilstanden. Desuden er der ind-For adjusting the base current of transistor T2, an adjustable resistor is used whose outlet is mechanically connected to the motor M, so that the motor is always activated in the direction of the equilibrium state. In addition, there are
