Description

Przedmiotem wynalazku jest urzadzenie frezujace do uprawy gleby.The subject of the invention is a milling device for soil cultivation.

Znana jest glebogryzarka do uprawy gleby, która^posiada wal ze specjalnie uksztaltowanymi zebami. Zeby te podczas pracy glebogryzarki tna i mieszaja glebe nie zapewniajao jednak pelnej jej odwracalnosci przy czym ruch posuwowy glebogryzarki i obroty walu sa zwykle wspólbiezne. Wa£ glebogryzarki otrzymuje naped z ciagnika, do którego jest ona podwieszona. W czasie pracy glebogryzarki ciecie i mieszanie gleby wymaga duzego zuzycia energii.There is a known tiller for soil cultivation which has a roller with specially shaped teeth. In order to these during operation, the rotary tiller cuts and mixes the soil, however, did not ensure its full reversibility, while The feed motion of the rotary tiller and the shaft rotation are usually concurrent. The shaft of the tiller is driven from the tractor to which it is attached. During operation of the tiller, cutting and mixing the soil is required high energy consumption.

Celem wynalazku jest wyeliminowanie wspomnianych wad i niedogodnosci przez skonstruowanie urzadzenia zapewniajacego równomierna i pelna odwracalnosc uprawianej gleby bez tworzenia grobli i bruzd, przy uzyciu mniejszych sil napedu i przy mniejszym zuzyciu energii. Cel ten spelnia urzadzenie wedlug wynalazku którego elementy skrawajace dzialajac na zasadzie frezowania przeciwbieznego nabieraja na siebie kesy gleby, a nastepnie zrzucaja w to samo miejsce z tym, ze czastki gleby znajdujace sie pierwotnie na wierzchu uprawianego pola umieszczane sa na spodzie i odwrotnie - czastki bedace pierwotnie na spodzie uprawianej warstwy gleby umieszczane sa na wierzchu.The object of the invention is to eliminate the drawbacks and inconveniences mentioned by design a device ensuring even and full reversibility of the cultivated soil without creating dikes and furrows, using smaller drive forces and with less energy consumption. This goal is fulfilled by the device according to the invention, the cutting elements of which, acting on the principle of up-milling, take on each other debris the soil, and then dump to the same place with the fact that the soil particles were originally on top the cultivated field is placed on the bottom and vice versa - the particles that were originally on the bottom of the cultivated field layers of soil are placed on top.

Urzadzenie wedlug wynalazku posiada elementy skrawajace, zamocowane przegubowo w tarczach i suwliwie w bebnie. Tarcze i beben maja osie wzgledem siebie przesuniete na odleglosc zblizona do polowy róznicy ich srednic i sa napedzane w tym samym kierunku i z taka sama predkoscia katowa. Na skutek tego elementy skrawajace nabieraja kesy gleby metoda frezowania przeciwbieznego, a nastepnie zrzucaja czastki tych kesów w kolejnosci odwrotnej w to samo miejsce z którego zostaly pobrane.The device according to the invention has cutting elements articulated in the discs and slickly in the drum. The discs and the drum have their axes approximately halfway apart from each other difference in diameter and are driven in the same direction and with the same angular speed. As a result of this the cutting elements take the soil by the counter-milling method, and then drop the particles of these keses in reverse order to the same place from which they were taken.

Zastosowanie urzadzenia frezujacego do uprawy gleby zapewnia w porównaniu z glebogryzarka pelna i zalozona odwracalnosc warstwy uprawianej gleby i mniejsze zuzycie energii.The use of a milling device for soil cultivation is ensured by comparison with a full rotary tiller and the assumed reversibility of the cultivated layer and lower energy consumption.

Przedmiot wynalazku uwidoczniony jest na rysunku, na którym fig. 1 przedstawia urzadzenie w widoku z boku, a fig. 2 — w widoku z przodu.The subject of the invention is illustrated in the drawing, in which Fig. 1 shows the device in view from the side, and fig. 2 is a front view.

Urzadzenie ma elementy skrawajace 3 zamocowane przegubowo w tarczach 1 w punktach 4 oraz suwliwie w prowadnicach 5 bebna 2, przy czym prowadnice 5 maja postac szczelin pomiedzy rynnami 6. Osie 0! i 022 103 170 zespolu tarcz 1 i bebna 2 sa odpowiednio wzgledem siebie przesuniete, przy czym ta odleglosc jest zblizona do polowy róznicy ich srednic.The device has cutting elements 3 articulated in the discs 1 at points 4 and slidably in the guides 5 of the drum 2, while the guides 5 have the form of gaps between the gutters 6. Axes 0! and 022 103 170 of the group of discs 1 and drum 2 are respectively offset from each other, this distance being approximate to half the difference in their diameter.

Naped na tarcze 1 i beben 2, które z kolei stanowia zespól napedowy elementów skrawajacych 3 przekazywany jest z ciagnika przez zespól walów i kól zebatych w ten sposób, ze tarcze 1 i beben 2 wykonuja ruch obrotowy w tym samym kierunku z jednakowa predkoscia katowa. Nabierane przez elementy skrawajace 3 kesy gleby przesypuja sie po blaszanych rynnach 6.Drive for disc 1 and drum 2, which in turn constitute a drive unit for cutting elements 3 is transmitted from the tractor through the group of rollers and gears in such a way that discs 1 and drum 2 are Rotary movement in the same direction with equal angular speed. Picked up by cutting elements 3 the soil is poured over the metal gutters 6.
