Description

Predmet izuma Subject of the invention

Predmet izuma je traktorski priključak kultivatora, pri čemu je priključak predviđen za smještaj na traktor preko standardnog priključka u tri točke na stražnjem dijelu traktora. The subject of the invention is the tractor connection of the cultivator, whereby the connection is designed to be placed on the tractor via a standard three-point connection on the back of the tractor.

Tehnički problem Technical problem

Tehnički problem, koji ovaj izum treba riješiti je kako stvoriti traktorski priključak kultivatora, koji bi omogućio u određenom području spoj s podešavanjem kultivatora poprečno na pomak vozila s kultivatorom, u svrhu prilagodbe kultivatora kosini terena koje se obrađuje u odnosu na ravninu po kojoj se traktor vozi i istovremeno ručnu prilagodbu inače automatskog sigurnosnog vratila za odmak kultivatora prilikom dolaska na prepreku. The technical problem that this invention needs to solve is how to create a cultivator tractor connection, which would enable in a certain area a connection with the adjustment of the cultivator transversely to the displacement of the vehicle with the cultivator, in order to adapt the cultivator to the slope of the terrain being cultivated in relation to the plane on which the tractor is driven and at the same time manual adjustment of the otherwise automatic safety shaft for the movement of the cultivator when approaching an obstacle.

Poznato stanje tehnike Known state of the art

Prema patentnom spisu SI 20711 (BMK Engineering d.o.o.) poznat je traktorski priključak kultivatora takve vrste. Pokazala se potreba za veći kut poprečnog nagiba kultivatora na standardnom traktorskom priključku radi obrade po padinama uz ceste, u vinogradima itd. Spomenuta uporaba poznatog kultivatora je zahtijevala razvoj naprave iste vrste sa ugrađenim sigurnosnim vratilom, koji bi trebao omogućiti automatski odmak od prepreke, npr. stabla, kamena, stupica uz cestu itd. According to the patent document SI 20711 (BMK Engineering d.o.o.), a tractor attachment of a cultivator of this type is known. The need for a larger angle of transverse inclination of the cultivator on a standard tractor attachment for cultivation on slopes along roads, in vineyards, etc. was shown. trees, stones, posts along the road, etc.

Rješenje tehničkog problema A solution to a technical problem

Opisani tehnički problem je riješen napravom prema izumu, čija je značajka u tome, što je hidraulični klip, koji je predodređen za okret kultivatora oko uzdužnog pogonskog vratila, prednosno kardanskog, učvršćen na šarki koja ga povezuje s paralelogramskom konzolom, koja je upeta na standardnom traktorskom priključku u tri točke, pomoću dva luka, koji zajedno tvore približno puni kut, a u poprečnom smjeru su pomaknuti, pri čemu je između njihovih susjednih krajeva uležištena jedna ušica hidrauličnog klipa, dok je druga ušica tog hidrauličnog klipa uležištena na kućištu kultivatora. Takvo učvršćenje omogućuje nesmetan veći okret kultivatora nego što je to slučaj kod istovrsnih poznatih kultivatora. Spomenuta paralelogramska konzola je izvedena s jednim uzdužnim krakom na teleskopski način tako, da je u radnom položaju taj krak u svojem najkraćem stanju, u kojem ga pridržava barem jedna opruga. Prilikom naslanjanja kultivatora na prepreku, teleskopski krak se automatski rastegne, kultivator se time postavi koso prema osi traktora i sa tako preoblikovanom paralelogramskom konzolom zaobiđe prepreku bez ikakvih oštećenja. The described technical problem is solved by the device according to the invention, the feature of which is that the hydraulic piston, which is intended for turning the cultivator around the longitudinal drive shaft, preferably cardan, is fixed on a hinge that connects it to the parallelogram console, which is clamped on a standard tractor connection in three points, by means of two arcs, which together form an approximately full angle, and are shifted in the transverse direction, whereby one eyelet of the hydraulic piston is inserted between their adjacent ends, while the other eyelet of this hydraulic piston is inserted on the body of the cultivator. Such a fixture enables a larger turn of the cultivator than is the case with similar known cultivators. The aforementioned parallelogram console is made with one longitudinal arm in a telescopic manner, so that in the working position this arm is in its shortest state, in which it is supported by at least one spring. When leaning the cultivator on an obstacle, the telescopic arm is automatically stretched, the cultivator is thus placed diagonally to the tractor axis and with the parallelogram console thus reshaped, bypasses the obstacle without any damage.

Karakteristike naprave prema izumu, podrobnije će biti objašnjene opisom izvedbenog primjera i slikama, na kojima se prikazuje: The characteristics of the device according to the invention will be explained in more detail by the description of the embodiment and the pictures, which show:

Sl. 2 presjek iste naprave po liniji II-II sa slike 1. Sl. 2 section of the same device along line II-II from Figure 1.

Traktorski priključak kultivatora je izveden iz standardnog priključka 1 u tri točke, koji je učvršćen na tri mjesta na stražnjem dijelu traktora, koji nije prikazan na slikama. The tractor connection of the cultivator is derived from the standard connection 1 in three points, which is fixed in three places on the rear part of the tractor, which is not shown in the pictures.

Na priključku 1 u području pogonskog vratila 2, koje je upeto na jednoj strani u traktorski pogon, koji nije prikazan na slikama, izvedena je šarka 3 paralelogramske konzole 4. Jedan uzdužni krak 5 te konzole 4 je krut, dok je drugi krak 6 rastezljiv, pri čemu ga barem jedna opruga 7 prisiljava da se sastavi do najkraće duljine. Opruge 7 su najbolje vijčane i upete u ušice 8 na svakom dijelu kraka 6 s po jednim krajem. Korisnik može promijeniti broj opruga 7 ručno na licu mjesta i time prilagoditi djelovanje naprave prema izumu prema trenutnim zahtjevima na terenu. At connection 1 in the area of the drive shaft 2, which is clamped on one side to the tractor drive, which is not shown in the pictures, there is a hinge 3 of the parallelogram console 4. One longitudinal arm 5 of that console 4 is rigid, while the other arm 6 is stretchable. whereby at least one spring 7 forces it to fold to the shortest length. The springs 7 are best screwed and inserted into the lugs 8 on each part of the arm 6 with one end each. The user can change the number of springs 7 manually on the spot and thereby adjust the operation of the device according to the invention according to the current requirements in the field.

Oba kraka 5 i 6 paralelogramske konzole 4 su međusobno povezani aktivatorom 9, najbolje hidrauličnim cilindrom, preko kojega korisnik privlači kultivator u poprečnom smjeru u odnosu na traktor, Čime se djelovanje naprave prilagođava trenutnom stanju. Both arms 5 and 6 of the parallelogram console 4 are interconnected by an activator 9, preferably a hydraulic cylinder, through which the user pulls the cultivator in a transverse direction relative to the tractor, whereby the action of the device is adapted to the current state.

Paralelogramska konzola 4 je na drugom kraju uležištena u glavčinu 10 pogonskog vratila 2. Na glavčini 10 je sa stražnje strane namješten kultivator 11. Na glavčini 10 je nadalje smješten par lučnih držača 12. Držači 12 su smješteni na razmaku i međusobno paralelno. Na slobodnim krajevima držača 12 uležišten je aktivator 13, najbolje hidraulični cilindar, koji okreće kultivator 11 oko uzdužne osi pogonskog vratila 2. Aktivator 13 je na drugom kraju uležišten u kultivator 11. Spomenuto ležište aktivatora 13 omogućava okret kultivatora 11 oko osi vratila 2 u području preko 90°. At the other end, the parallelogram console 4 is inserted into the hub 10 of the drive shaft 2. A cultivator 11 is mounted on the hub 10 from the rear. An activator 13, preferably a hydraulic cylinder, is mounted on the free ends of the holder 12, which rotates the cultivator 11 around the longitudinal axis of the drive shaft 2. The activator 13 is mounted on the other end in the cultivator 11. over 90°.

Razumljivo je da stručnjak u području ovog izuma može smisliti i drugačije izvedbene primjere, bez da izađe iz okvira novosti i karakteristika izuma, koje su određene u sljedećim patentnim zahtjevima. It is understandable that an expert in the field of this invention can come up with other implementation examples, without going beyond the novelty and characteristics of the invention, which are specified in the following patent claims.
