Description

Vynález sa týká ryhovača s druhotným pohybom pre vysadzovacie stroje, najma pre sadzače semenačky cukrovej a křmnej řepy so znížením pracovného odporu.BACKGROUND OF THE INVENTION The present invention relates to a secondary movement trencher for planting machines, in particular for planters of sugar and fodder beet seedlings with reduced working resistance.

V posledných rokoch narastajú nároky na minimalizáciu pracovných operácií pri ροϊnohospodárskych prácach a z hladiska energetických nárokov i zníženie ťažnej sily energetických prostriedkov. V súčasnosti sa pri vysadzovaní okopanin, pre vytvorenie sadbového lůžka, používajú radlice s pasivným pohybom, to znamená bez přídavného pohybu umožňujúceho zmenšenie odporu a tým i tažnej sily energetického prostriedku.In recent years, there has been a growing demand for minimizing work operations in agricultural work and, in terms of energy demands, a reduction in the traction power of energy resources. At present, when planting root crops, passive motion coulters are used to form the seedbed, i.e. without additional movement allowing to reduce the resistance and hence the tensile force of the energy means.

Zníženie měrného odporu je prevažne riešené híadaním najvhodnejšieho tvaru pasivného nástroja jeho velkosti a umiestnenia na sadzacom stroji.The reduction of the resistivity is predominantly solved by searching for the most suitable shape of the passive tool of its size and location on the typesetting machine.

V súčasnosti sa používajú pevné stípové ryhovače radličného systému v tvare klinu so zvislými počnými stěnami.At the present time, wedge-shaped rigid tine trench coulters with vertical front walls are used.

Nevýhodou týchto ryhovačov je, že bočné steny radlice roztláčajú zem do stráň, čím dochádza k nežiadúcemu nakypreniu půdy v medziriadkoch a k jej vysychaniu. Je tu zároveň i velká spotřeba mechanickej práce prejavujúca sa v zvýšení ťažnej sily energetického prostriedku v závislosti so zvýšeflQU měrnou spotřebou paliva,The disadvantage of these trenches is that the side walls of the coulter push the ground into the slopes, causing undesirable loosening of the soil in the intermediate rows and drying. At the same time, there is also a large consumption of mechanical work resulting in an increase in the pulling power of the energy means as a function of the increase in specific fuel consumption,

Vyššie uvedené nedostatky odstraňuje ry2 hovač s druhotným pohybom, najmá pre vytváranie ryhy pre sadzač semenačky cukrovej a křmnej řepy, ktorého podstatou je, že pozostáva z kolmo orientovanej dvojchodej závitovice navinutej na kuželové duté těleso, pričom dvojchodé závitovice je zo zadnej strany zakryta tvarovým oblúkovým krytom ukončeným nad pracovnou špičkou závitovice.The aforementioned drawbacks are eliminated by a secondary movement trencher, in particular for forming a groove for the planter of sugar beet and fodder beet, which consists in that it consists of a perpendicularly oriented double-walled coil wound on a conical hollow body, the double-walled coil terminated above the helix tip.

Výhodou navrhovaného riešenia je, že prudko poklesne náročnost na energetický zdroj, pretože miesto pasivného odporu klasických rozhrňovacích radlic je tu odpor proti rotácii závitovice zatláčanej priamočiarým pohybom do čelnej steny brázdy. Tento odpor je překonávaný krútiacim momentem od vývodového hriadeta traktora, resp. hydromotorom. U klasického spůsobu je potřebná vel'ká tažná sila a z toho plynúca potřeba velkej adhézie na žádných kolesách traktora.The advantage of the proposed solution is that the intensity of the energy source decreases sharply, because instead of the passive resistance of conventional shear coulters, there is resistance to the rotation of the helix pushed by a linear motion into the front wall of the furrow. This resistance is overcome by the torque from the tractor PTO shaft, respectively. hydraulic motor. In the classical way, a great pulling force is required and the consequent need for a great adhesion on any tractor wheels.

Tým, že závitovica iba vyfrézuje rýhu o potrebnej šírke a medziriadky zostanú nepohnuté, nedochádza k nežiadúcemu presychaniu půdy v medziriadkoch.By only milling the groove of the required width and keeping the intermediate rows intact, there is no undesired over-drying of the soil in the intermediate rows.

Nedochádza k vyhlbovaniu zariadenia ani k upchávaniu nerozloženou slámou a inými překážkami. Tieto sú odhadzované na bok a nesposobujú zbytočne prestoje na čiastenie zariadenia. Ak sú zaorané jesennou orbou hnojivá do zásoby, možno úplné vynechat operáciu kyprenia kombinátorom. Liadkovanie možno robit na povrch parcely bez zvláštneho zapravovania.The machine does not shake or clog with unattached straw and other obstructions. These are discarded sideways and do not cause unnecessary downtime for part of the equipment. If the fertilizer is plowed through the autumn plowing, the combing operation can be omitted completely. Lining can be done on the parcel surface without special incorporation.

Příkladné prevedenie ryhovača s druhotným pohybom je znázorněné na priloženom výkrese, kde na obr. 1 je znázorněný čelný pohtad na ryhovač a na obr. 2 je bočný pohl'ad.An exemplary embodiment of a secondary trench is shown in the accompanying drawing, in which: FIG. 1 is a front view of the trench, and FIG. 2 is a side view.

Ryhovač s druhotným pohybom pozostáva z dvojchodej závitovice 1, ktorá je navinutá na dutom kužetovom telese 2. Duté kuželové teleso 2 v hornej časti prechádza do válcového tvaru 3. Zadná strana dutého kuželového telesa 2 je zakrytá tvarovým oblúkovým krytom 4, s výrezom 5, upevněným skrutkami 13 na telese převodovky 12. Pracovna špička 6 je po celom obvode otvorená. Na vrchole dutého kuželového telesa 3 a dvojchodej závitovice 1 je umiestnený rozstrekovací krúžok 7. Celé zariadenie je prostredníctvom čapu 8 rotačně spojené s převodovkou 12.The secondary trench consists of a double-threaded screw 1, which is wound on a hollow cone body 2. The hollow conical body 2 at the top passes into a cylindrical shape 3. The rear side of the hollow conical body 2 is covered by a shaped arch cover 4, with a cutout 5 by means of screws 13 on the gearbox housing 12. The working tip 6 is open all around. At the top of the hollow conical body 3 and the double-walled screw 1 is a spray ring 7. The entire device is rotatably connected to the gearbox 12 via a pin 8.

Po uvedení zariadenia do rotačného pohybu sa zahíbi závitovica 1 za súčasného priamočiareho pohybu vpřed. Vzhladom na to, že závitovica 1 pracuje ako pódny vrták, je v jej zadnej časti umiestnený tvarový oblúkový kryt 4 umožňujúci pomocou rozstrekovacieho krúžka 7, cez výřezy 5 odhadzovat vyhrnutá půdu do medziriadkov 9. Otvorená pracovná špička 6 vracia časť od frézovanej půdy 11 na dno ryhy 10 a tým uíahčuje do takto nakyprenej půdy sadit repné bulvičky.After the device has been rotated, the screw 1 is heated with a straight forward movement. Since the screw 1 acts as a drill bit, a shaped arc cover 4 is provided in its rear part to allow the soil to be thrown into the intermediate rows through the slots 5 via the slots 5. The open working tip 6 returns a part of the milled soil 11 to the bottom. grooves 10, thereby facilitating the planting of the beet bulbs into the soil.
