Vynález sa týká zariadenia na vyzúvanie obuvi z kopýt, najma lámacíoh, uloženýchna nosiči prostredníctvom vyzúvacieho nástroja upraveného na vyzúvacej tyči. vačšina známých zariadení, používaných na vyzúvanie obuvi z kopýt, má možné ovládanie.Toto je volené preto, lebo obsluha zariadenia potřebuje pri vyzúvaní óbe ruky. Vzhladomna vysoký výkon nožné ovládanie nevyhovuje predpisom určujúcim maximálně použitie nožnéhoovládača. Je známe zariadenie na vyzúvanie lámacích kopýt s dvojicou bočných zvierok preuchopenie topánky v priehlavku.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe hoisting device, in particular a sleeve, mounted on a carrier by means of a slipping tool provided on the sliding rod. Most of the known devices used to lift shoes from hooves have a possible control. This is because the operator of the device needs a hand to retract. The high performance of the foot control does not comply with the regulations governing maximum use of the foot controller. There is a known device for retracting breaking hooves with a pair of side clamps to grab the shoe in the instep.

Patná část topánky je zovretá vo formě, zatial čo patná část kopyta sa posuniedole, čím sa kopyto zlomí. Zvierky topánku zovrú a pohybom k Špici vyzujú topánku z kopyta.Ďalej je známe zariadenie, kde kopyto sa nasadí na třň, upevněný na stojane. Vyzúvaniesa robí gumovou poduškou, upevněnou na hornom konci výkyvného stojanu v Iahko snímatelnomvozíku. Stojan je spojený systémom výkyvných pák s dvoma valcami, ktoré posunujú prítlačnúpodušku vo vodorovnom smere, poduška je pritlačovaná k obuvi a potom v kolmom smerea obuv sa vyzúva.The heel of the shoe is clamped in the mold, while the bottom of the shoe is shifted to break the hoof. The shoes of the shoe clamp and move to the toe to encourage the shoe to be hoofed. The cushioning makes a rubber cushion mounted on the upper end of the swinging stand in an easily removable cushion. The stand is connected by a system of swinging levers with two rollers, which push the pressing pad in the horizontal direction, the cushion is pressed against the shoe and then in the perpendicular direction the shoe is lifted.

Dlžka posunu podušky je obmedzená skrutkovými zarážkami. Přítlačná poduška sa vymieňapodlá tvaru a rozmerov obuvi. Známe je tiež vyzúvacie zariadenie obuvi z kopýt, pri ktoromsa používá plyn, zavádzaný medzi kopyto a topánku, přitom systém podušiek zvonka zvieratopánku po celej dížke stráň a napomáhajú vyzúvaciemu účinku plynu, ktorý tlačí zvnútra.The length of the cushion shift is limited by screw stops. The pressure pad is changed according to the shape and size of the shoe. Also known is a shoe hoeing device which uses gas introduced between the hoof and shoe while the cushioning system of the outside of the animal laces along the entire length and aids in the shifting effect of the gas being pushed from the inside.

Tieto zariadenia majú nevýhodu v tom, že sú konštrukčne zložité, náročné na přesnostvyhotovenia, z čoho vyplývajú aj nároky na údržbu. Nevýhodou je tiež skutočnosť, žekonštrukčne sú zariadenia riešené prevažne s hydraulickým pohonom, čím je daná rélatívnenízká pracovná rýchlosť. Niektoré zariadenia sú zaradené do výrobných liniek ako jedno-účelové, čo obmedzuje ich použitie.These devices have the disadvantage that they are structurally complex, exacting in precision, and thus require maintenance. The disadvantage is also the fact that the devices are mainly designed with a hydraulic drive, thus giving a low working speed. Some devices are included in production lines as single purpose, which limits their use.

Tieto nevýhody do značnéj miery odstraňuje zariadenie podlá vynálezu,ktorého podstataspočívá v tom, že nosič kopyta je připojený ku kolenovým pákám a prostredníctvom tiahlak riadiacej páke ukončenej přítlačnou a odtrhovou kladkou, ktoré sú vedené přítlačnoua odtrhovou vačkou, upevněnou na klukovom hriadeli, na ktorom sú upravené ojnica spojenáotočným čapom s vyzůvacou týčou, unášač a šnekové kolo, ktoré je v zábere so šnekomhnacieho hriadela. Ďalším podstatným znakom je to, že na riadiacej páke je upravená zapínacia páčkaso zdvíhacou kladkou, ktorá je v zábere so spúšťacou páčkou, do ktorej zapadá zapínacípalec unášača. Kolenová páka je připojená k pružinovej poistke.These drawbacks are largely eliminated by the device according to the invention, which consists in that the last carrier is connected to the knee levers and by means of a pulling lever controlled by a pressing and tearing pulley, which are guided by a pressing and tearing cam fixed to the crankshaft on which connecting rod with a swivel pin with a tapering rod, a carrier and a worm wheel that engages with the worm shaft. A further essential feature is that on the steering lever there is a closing lever provided with a lifting pulley which engages with a trigger lever that engages the engagement pin of the carrier. The knee lever is attached to the spring lock.

The last support 11 of the hoof 35 is connected to the knee levers 13, 14, one of which is connected to the rod. 10, the second spring spring 15 to which the pressure spring 29 pushes the adjusting screw 28. The rod 10 is connected to the control lever 2 on which the pressure roller 22 is provided, the tear roller 23 and the closing lever 24. The pressure roller 22 rolls on the presser 2 » attached to the crankshaft 5 on which the tear cam 7 is further mounted, after which the tear-off roller 23 rolls again. The operation of the device is as follows. After the shoe 35 has been fitted with the shoe 36 on the pin 21 of the carrier 11, the operator 11 pushes the carrier 11 towards the retracting tool 16. The carrier 11 is rotated about the pivot 12, thereby pivoting the pair of knee levers 13, 14, the rod 10 being pushed down and turning the steering lever 2 in clockwise direction. After a certain rotation of the control lever 2, the lifting pulley 25 of the engaging lever 24 lifts the release lever 26 so much that it releases the engaging thumb 27 of the driver 8. By rotating the crankshaft 5, the pressure cam 6 raises its pressure roller 22, thereby turning the control lever 9 to an extreme position. The control lever 9, by means of the rod 10, straightens the knee levers 13, 14, thereby exerting a pressure on the carrier 11 with the hoof 35 to retract the tool 16. The pressure cam 6 also has the timing that at the moment of the bottom dead center of the crankshaft 2, the full pressure of the hoof 35 is reached to the retracting tool 16. In the case of exceeding the maximum thrust force, the spring lock 15 pivotes against the compression spring 29. By further turning the crankshaft 2, the connecting rod 20 lifts the retracting rod 17 with the retracting tool 16, and the shoe 36 is removed from the hoof 32. thereby rotating the control lever 9 to the base position. The control lever 2 over the rod 10 and the knee levers 12, 14 returns the hoof carrier 11 to the base position. By the action of the connecting rod 20, the retracting rod 17 with the retraction tool 16 decreases and returns to the lower position. Before reaching the base position, the closing thumb 27 runs on the lowering lever 26, which pulls it out of engagement. In this way, the clutch (not shown) is switched off and the device is stopped in its basic position. After removing the hoof 35 from the pin 21 of the carrier 11, the device is ready for the next duty cycle. SUBJECT OF THE INVENTION
