Abstract

A tractor's mulcher attachment executed from a standard triangular attachment (1) is three-point attached to the rear part of a tractor, in which case there is a pivot (3) of a parallelogram console (4) carried out on the attachment (1) in the vicinity of a driving shaft (2) which is clamped into a tractor's power take-off on the one side. Both console arms (5) and (6) are interconnected by an actuator (9), preferentially a hydraulic cylinder. On the other side, the parallelogram console (4) is bearing- mounted into a hub (10) of the driving shaft (2), where a mulcher (11) is mounted on the hub (10) from the rear side. One longitudinal console (4) arm (5) is stiff and the other arm (6) is longitudinally extensible, where at least one spring (7) forces it to contract into the shortest length. On the hub (10), a pair of arc-shape holders (12) is installed, which are running parallel to each other at an interspace, in which case the actuator (13), preferentially a hydraulic cylinder, is embedded with one of its eyes between the free ends of the holders (12), while with its opposite end, it is embedded into the mulcher (11).

Description

[001] Predmet izuma je traktorski priključek mulčaija, pri čemer priključek predviden za namestitev na traktor preko standardnega tritočkovnega priključka na zadnjem delu traktoija.[001] The subject of the invention is a mulch tractor attachment, the attachment of which is intended to be mounted on the tractor via a standard three-point attachment at the rear of the tracto.

Tehnični problem [002] Tehnični problem, ki ga rešuje izum je, kako zasnovati traktorski priključek mulčaija, ki bo omogočal v določenem območju zvezno v nastavitev mulčaija prečno na pomik vozila z mulčaijem zaradi prilagoditve mulčarja naklonu obdelovanega terena glede na ravnino, po kateri vozi traktor in hkratno ročno prilagoditev sicer samodejnega odmičnega varovala mulčaija pri naletu na oviro.Technical Problem [002] The technical problem solved by the invention is how to design a tractor mulch attachment that will allow the mulch to be adjusted transversely to the mulch vehicle in a certain area in order to adjust the mulch to the slope of the cultivated terrain with respect to the plane along which the tractor travels and the simultaneous manual adjustment of an otherwise automatic mulchai camber when encountering an obstacle.

Znano stanje tehnike [003] Po patentnem spisu SI 20711 (BMK Engineering d.o.o.) je znan tovrstni traktorski priključek mulčarja. Pokazala se je potreba po večjem kotu prečnega nagibanja mulčarja na standardnem traktorskem priključku zaradi košnje po brežinah ob cestah, v vinogradih ipd. Navedena uporaba tega mulčarja je narekovala razvoj tovrstne naprave z vgrajeno odmično varovalko, ki naj bi omogočala samodejni odmik od ovire, npr. stebla, kamnov, cestnega stebrička, ipd.BACKGROUND OF THE INVENTION According to patent patent SI 20711 (BMK Engineering d.o.o.), this type of tractor attachment is mulch. There was a need for a greater angle of inclination of the mulch on the standard tractor attachment for mowing on the slopes along roads, in vineyards, etc. The stated use of this mulcher dictated the development of this type of device with a built-in fuse, which is supposed to allow automatic departure from the obstacle, e.g. stems, stones, road pillars, etc.

Rešitev tehničnega problema [004] Opisani tehnični problem je rešen z napravo po izumu, katere značilnost je v tem, daje hidravlični bat, ki je predviden za zasuk mulčarja okoli vzdolžne pogonske gredi, prednostno kardanske, vpet na tečaju, ki ga povezuje s paralelogramsko konzolo, ki ne vpeta na trikotnem standardnem traktorskem priključku, preko dveh lokov, ki skupaj tvorita približno polni kot in sta v prečni smeri zamaknjena, da je med njunima sosednjima koncema uležajeno eno uho hidravličnega bata, medtem ko je drugo uho tega hidravličnega bata uležajeno na okrovu mulčarja. Tako vpetje nudi neoviran večji zasuk mulčarja, od znanih tovrstnih mulčarjev. Navedena paralelogramska konzola je izvedena z enim vzdolžnim krakom v teleskopskem smislu in sicer tako, da je v delovni legi ta krak v svojem najkrajšem stanju, v katerem ga drži vsaj ena vzmet. Ob prislonu mulčarja ob oviro, se teleskopski krak samodejno raztegne, mulčar se s tem postani poševno glede na osi traktoija in s tako preoblikovano paralelogramsko konzolo obide oviro brez obojestranskih poškodb.Solution to a Technical Problem [004] The technical problem described is solved by a device according to the invention, characterized in that the hydraulic piston intended for rotating the mulch around the longitudinal drive shaft, preferably a cardan shaft, is mounted on a hinge connecting it to a parallelogram bracket , which are not clamped on a triangular standard tractor attachment, through two arches, which together form approximately a full angle and are displaced in a transverse direction so that one ear of the hydraulic piston is mounted between their adjacent ends while the other ear of that hydraulic piston is mounted on the housing mulch. Such clamping offers an unobstructed greater rotation of the mulch than the known mulchers of this type. The said parallelogram bracket is made with one longitudinal arm in the telescopic sense, so that in the working position this arm is in its shortest state and is supported by at least one spring. When the mulch is pushed against the obstacle, the telescopic arm is automatically extended, thereby mowing the mulch obliquely with respect to the axes of the tractoi, thus bypassing the parallelogram bracket bypassing the obstacle without mutual damage.
