For the loader operation, both linear hydraulic motors are connected in one hydraulic circuit of the working tool through dividers and a distributor.

Description
Zapojenie hydraulických iprvkov univerzálneho pracovného zariadenia je určené pre lopatové nakladače a rieši spojenie dvoch rozdielnych pracovných zariadení pre nakladač a rýpadlo do jedného celku s možnolsťou jednoduchej změny prlsposobenia pre vyžadovaná činnost stroja. Pre prácu nakladača sú obidva priamočiare hydromotory zapojené v jednom hydraulickom obvode pracovného nástroja prostredníctvom deličov a rozvádzača. Vyrovnávací priamočiary hydroimotor je zároveň vlečený prostredníctvom mechanického prepojenia hydromotormi zdvíhadla pracovného zariadenia, čím sposobuje prečerpávanie hydraulickej kvapaliny, a tým vyrovnávanie polohy pracovného nástroja.The connection of the hydraulic elements of the universal work equipment is designed for shovel loaders and solves the connection of two different work equipment for the loader and excavator into one unit with the possibility of a simple change of adaptation for the required operation of the machine. To operate the loader, both linear hydraulic motors are connected in one hydraulic circuit of the working tool by means of dividers and distributor. At the same time, the compensating linear hydraulic motor is towed by means of mechanical interconnection by the hydraulic motors of the lifting device of the working equipment, thereby causing the hydraulic fluid to be pumped and thus balancing the position of the working tool.
Pre prácu rýpadla má každý priamočiary hydromotor samostatný hydraulický obvod, čo je sposobené přestavením deliča do druhej krajnej polohy, čím je zrušený vyrovnávací účinok hydromotora a pracovný nástroj zachovává polohu voči pracovnému zariadeniu.To operate the excavator, each linear hydraulic motor has a separate hydraulic circuit, which is caused by moving the divider to the second extreme position, thereby canceling the balancing effect of the hydraulic motor and maintaining the working tool position relative to the working equipment.

Vynález sa týká zapojenia hydraulických prvkov univerzálneho pracovného zariadenia nakladač—rýpadlo.The invention relates to the connection of hydraulic elements of a universal loader-excavator working device.
Doteraz známe zapojenia pracovného zariadenia naikladačov· sa zabezpečuje roznym kinematickým usporiadaním ako sú sústava pák a otočných čapov, hydraulická vazba a kombinácie týchto systémov. Pre činnost pracovného zariadenia nakladač—rýpadlo sú tieto zapojenia nežiadúce. Ich odstránenie si vyžaduje prestavenie otočných čapov a pák, čo je náročné na čas i fyzickú námahu.The hitherto known connections of the loader working equipment are provided by various kinematic arrangements such as lever and pivot linkages, hydraulic coupling and combinations of these systems. These connections are undesirable for the operation of the loader-excavator work equipment. Removing them requires adjusting the pivot pins and levers, which is time consuming and physical.
Uvedené nevýhody odstraňuje zapojenie hydraulických prvkov podlá vynálezu, jeho podstata spočívá v tom, že v pracovnom zariadení nakladače pracujú dva priamočiare hydromotory vzájomne přepojené cez dělič hydraulické]' kvapaliny na rozvádzač hydraulického systému a nádrž hydraulického média. V pracovnom zariadení rýpadlo pracuje na jeden priamočiary hydromotor, kým druhý je z okruhu vyřaděný deličom hydraulickej kvapaliny.The above-mentioned disadvantages are eliminated by the connection of the hydraulic elements according to the invention, which consists in the fact that two straight-line hydraulic motors are connected to each other via a hydraulic fluid divider to a hydraulic distributor and a hydraulic fluid reservoir. In the working equipment, the excavator operates on one linear hydraulic motor, while the other is excluded from the circuit by a hydraulic fluid separator.
Zapojenie hydraulických prvkov podlá vynálezu je možné využit v pracovnom zariadení univerzálnych nakladačov v spojení s výměnou pracovného nástroja. Výhodou tohoto riešenia je možnost okamžitej změny pracovného zariadenia z nakladača na rýpadlo bez zvýšeného úsilia obsluhy stroja.The connection of the hydraulic elements according to the invention can be used in the universal loader working device in conjunction with the replacement of the working tool. The advantage of this solution is the possibility of immediate change of working equipment from loader to excavator without increased effort of the machine operator.
Na připojených výkresoch je znázorněné zapojenie hydraulických prvkov univerzálneho pracovného zariadenia, kde na obr. 1 je bočný pohlad pracovného zariadenia nakladača a na obr. 2 je schéma hydraulického zapojenia prvkov pracovného zariadenia.The attached drawings show the connection of the hydraulic elements of the universal working device, where in FIG. 1 is a side view of the loader working apparatus; and FIG. 2 is a diagram of the hydraulic engagement of elements of a working device.
Výložník 1 je cez otočný čap 2 spojený s kozlíkom 3, pričom priamočiary hydromotor 4 je s výložníkom 1 přepojený čapom 6 a s kozlíkom 3 čapom 5. Priamočiary hydromotor 7 je na výložník 1 uchytený čapom 8 a k páke 9 čapom 10.The boom 1 is connected to the bearing bracket 3 by means of a pivot pin 2, the linear motor 4 being connected to the bracket 1 by a pin 6 and to the bracket 3 by a pin 5.
Priamočiary hydromotor 7 je prostredníctvom hydraulického potrubia 14, 17 z rozvádzača 19 hydraulickej kvapaliny přepojený s hydromotorom 4 pomocou deličov 11 a hydraulického potrubia 15, 18.The linear hydraulic motor 7 is connected via hydraulic lines 14, 17 from the hydraulic fluid distributor 19 to the hydraulic motor 4 by means of dividers 11 and hydraulic lines 15, 18.
Vyrovnávací priamočiary hydromotor 4 je prostrednictvom hydraulického· potrubia 15, 18 spojený pomocou deličov· 11 s odpadovým hydraulickým potrubím 18 do hydraulickej nádrže 20.The straightening hydraulic motor 4 is connected to the hydraulic reservoir 20 by means of dividers 11, via a separator 11, via a hydraulic line 15, 18.
Pohyb hydromotora 4 je závislý od pohybu hydromotorov 13, ktoré sú ovládané cez sekciu rozvádzača 19 hydraulickým médiom od hydrogenerátora 12.The movement of the hydraulic motor 4 is dependent on the movement of the hydraulic motors 13, which are controlled through the section of the distributor 19 by the hydraulic medium from the hydraulic generator 12.
Funkcia zapojenia hydraulických prvkov podlá vynálezu je v tom, že v prvej krajnej polohe ďeliča 11 dávajú do činnosti priamočiare hydromotory 4, 7 v jednom hydraulickom okruhu, v tomto případe je zabezpečená funkcia nakladača.The function of engaging the hydraulic elements according to the invention is that in the first extreme position of the divider 11, the linear hydraulic motors 4, 7 are actuated in one hydraulic circuit, in which case the function of the loader is ensured.
Přestavením deliča 11 do druhej krajnej polohy sa odpojí priamočiary hydromotor 4 a vzniknú 2 samostatné hydraulické okruhy, a týmto sposobom je zabezpečená funkcia pre rýpadlo.By moving the divider 11 to the second extreme position, the linear hydraulic motor 4 is disengaged and 2 separate hydraulic circuits are formed, thereby ensuring the function for the excavator.
