Description

Anordning ved gjødselspreder. Device for fertilizer spreaders.

Oppfinnelsen vedrører en anordning ved gjødselspreder for flytende stallgjødsel med en forrådsbeholder og en til denne koblet sprederanordning, bestående av et stort sett sylindrisk hus med en utløpsåpning i mantelflaten og på en sentralt gjennom huset forløpende aksel festede, radialt utadragende vinger. The invention relates to a device for a manure spreader for liquid stable manure with a storage container and a spreader device connected to this, consisting of a largely cylindrical housing with an outlet opening in the mantle surface and radially extending wings attached to a shaft running centrally through the housing.

I de senere år er anordning for gjødsling ved spyling i stadig større utstrekning kom-met til anvendelse, hvilken foruten at gjødslingen lettes, i høy grad også medfører den fordel at en blanding av gjødsel, opp-delt stråmateriale og urin samt vann fås, hvilket er særlig egnet for direkte utspred-ning på et felt beregnet for gjødsling. For dette øyemed er gjødselspredere kjent som har en sprederanordning bestående av et sylindrisk hus med i dette roterende vinger eller skovler. Slike spredere har imidlertid den ulempe at gjødselblandingen spres meget ujevnt utover, dvs. på enkelte avstander fra maskinen anbringes store mengder gjødselblanding, mens der på andre avstander anbringes så å si ikke noe gjødsel. Dene ujevne spredning medfører at veksten blir ujevn i tilsvarende grad, hvilket er særdeles ufordelaktig. In recent years, devices for fertilizing by flushing have increasingly come into use, which, in addition to making fertilizing easier, also has the advantage that a mixture of fertiliser, split straw material and urine as well as water is obtained, which is particularly suitable for direct spreading on a field intended for fertilization. For this purpose, fertilizer spreaders are known which have a spreading device consisting of a cylindrical housing with rotating vanes or vanes in it. However, such spreaders have the disadvantage that the fertilizer mixture is spread very unevenly outwards, i.e. at certain distances from the machine, large amounts of fertilizer mixture are placed, while at other distances no fertilizer is placed, so to speak. The uneven spread means that the growth becomes uneven to a corresponding degree, which is extremely disadvantageous.

Formålet med oppfinnelsen er å elimi-nere denne ulempe ved kjente gjødselspre-dere, og dette oppnås ved at samtlige eller noen, fortrinnsvis annenhver, av vingene på i og for seg kjent måte har en eller flere uttagninger i eller smalner mot sin nærmest mantelflaten beliggende ende. The purpose of the invention is to eliminate this disadvantage of known fertilizer spreaders, and this is achieved by all or some, preferably every other, of the wings in a manner known per se having one or more recesses in or narrowing towards the one closest to the mantle surface end.

Ved denne reduksjon av vingenes ender By this reduction of the ends of the wings

kan oppnås meget jevn spredning. very even dispersion can be achieved.

Oppfinnelsen skal i det efterfølgende beskrives nærmere under henvisning til tegningen som viser utførelseseksempler. Fig. 1 viser skjematisk en gjødselspre-der sett bakfra til anskueliggjørelse av en sprederanordning ifølge oppfinnelsen. Fig. 2—4 viser i større målestokk for-skjellige utførelser av sprederanordningens vinger eller skovler. Fig. 1 viser skjematisk sett bakfra en gjødselspreder beregnet for tilkobling til en traktor og bestående av en beholder 10 med påfyllingsanordning 11 og med hjul forsynt understell 12. Beholderen har bak-på en sprederanordning som generelt er betegnet med 13 og består av et sylindrisk hus 14, en sentralt gjenom huset forlø-pende drivaksel 15, lagret i husets endefla-ter og ragende ut av husets mot traktoren vendte endeflate, samt forløper langs med beholderen 10 for kobling til traktorens kraftuttak. På drivakselen er festet i huset roterbare vinger 16 som i det efter-følgende skal beskrives nærmere. I den endeflate av huset som vender mot beholderen, er anordnet en ikke vist innløpsåpning og i dens mantelflate en utløpsåpning 17, foran hvilken på passende konvensjonell måte er svingbart anordnet en lukelignende skjerm 18. In what follows, the invention will be described in more detail with reference to the drawing showing exemplary embodiments. Fig. 1 schematically shows a fertilizer spreader seen from behind to illustrate a spreader device according to the invention. Figs 2-4 show on a larger scale different designs of the spreading device's wings or vanes. Fig. 1 shows a schematic view from the rear of a fertilizer spreader intended for connection to a tractor and consisting of a container 10 with a filling device 11 and a wheeled undercarriage 12. The container has a spreading device at the back which is generally denoted by 13 and consists of a cylindrical housing 14, a drive shaft 15 extending centrally through the housing, stored in the end surfaces of the housing and projecting from the end surface of the housing facing the tractor, and extends along the container 10 for connection to the tractor's power take-off. Rotatable wings 16 are attached to the drive shaft in the housing, which will be described in more detail below. In the end surface of the housing facing the container, an inlet opening (not shown) is arranged and in its mantle surface an outlet opening 17, in front of which a hatch-like screen 18 is pivotably arranged in a suitable conventional manner.

Det er anordnet åtte vinger 16, av hvilke fire 16a på vanlig måte strekker seg frem til husets 14 mantelflate, mens de øvrige fire 16b har redusert areal. Re-duksjonen av arealet gir jevnere utspred-ning av gjødselen og kan enten oppnås ved i ytterenden av vingen å anordne en sen-tral uttagning som vist i fig. 2, eller for-skjellige store kantuttagninger som vist i fig. 4. Selvsagt er mange andre former for uttagninger mulige, og den uttagning som er gunstigst beror på beskaffenheten av den gjødsel som skal utspres. Eight wings 16 are arranged, of which four 16a extend in the usual way to the casing surface 14, while the other four 16b have a reduced area. The reduction of the area gives a more even spread of the fertilizer and can either be achieved by arranging a central outlet at the outer end of the wing as shown in fig. 2, or various large edge recesses as shown in fig. 4. Of course, many other forms of sampling are possible, and the sampling that is most favorable depends on the nature of the fertilizer to be spread.

Den foran utløpsåpningen svingbart anordnet skjerm 18 er innrettet for å re-gulere den fra utløpsåpningen kommende gjødselstrøms retning i høyden. The screen 18 pivotably arranged in front of the outlet opening is designed to regulate the height direction of the fertilizer flow coming from the outlet opening.

Oppfinnelsen er ikke begrenset til det foran beskrevne og på tegningen viste, men kan modifiseres på flere måter innenfor rammen av påstandene. The invention is not limited to what is described above and shown in the drawing, but can be modified in several ways within the scope of the claims.
