Изобретение относитс к сельскохоз йственному машиностроению, в частности к оруди м дл ухода за насаждени ми на каменистых и щебенистых почвах.The invention relates to agricultural machinery, in particular, tools for the maintenance of plantings on stony and stony soils.

Известен культиватор, состо щий из рамы с закрепленными на ней с возможностью поворота в горизонтальной плоскости рабочими органами 1 .A cultivator is known, which consists of a frame with working elements fixed on it so that it can rotate in a horizontal plane.

Недостатками известного культиватора вл ютс отклонение носка лапы при встрече с преп тствием и расположение лапы боком к обрабатываемой полосе, что снижает качество обработки и повыщает нагрузку на лапу и элементы креплени .The disadvantages of the known cultivator are the deviation of the toe of the paw when meeting with an obstacle and the location of the paw sideways to the treated strip, which reduces the quality of processing and increases the load on the paw and fasteners.

Известен также культиватор дл обработки каменистых и щебенистых почв, включающий ра.му с поперечным брусом и рабочие органы, закрепленные на нем посредством горизонтально установленных щарнирных четырехзвенников, имеющих переднее и заднее звень , св занные продольными т гами 2.A cultivator for treating stony and rubbly soils is also known, including a frame with a crossbar and working bodies attached to it by means of horizontally mounted hinged four-link hinges with front and rear links connected by longitudinal drafts 2.

Недостатком этого культиватора вл етс невысока жесткость элементов щарнирного четырехзвенника, что приводит к поло .мкам при встрече с прем тствием и снижению надежности работы.The disadvantage of this cultivator is the low stiffness of the elements of the hinged four-barter, which leads to cusps when meeting with the impact and reducing the reliability of operation.

Цель изобретени - повышение надежности конструкции культиватора.The purpose of the invention is to increase the reliability of the design of the cultivator.

Поставленна цель достигаетс тем, что 5 рама снабжена дополнительным поперечным брусом, который расположен за основным , а продольные т ги четырехзвенных механизмов выполнены с консол ми дл взаимодействи с позади расположенным 10 поперечным брусом, причем рабочий орган размещен в средней части заднего звена.The goal is achieved by the fact that frame 5 is equipped with an additional transverse bar which is located behind the main one, and the longitudinal rods of the four-link mechanisms are made with consoles for interacting with the transverse bar located behind 10, with the working body placed in the middle part of the rear link.

На фиг. 1 изображен культиватор дл обработки каменистых и щебенистых почв, вид сбоку; на фиг. 2 - то же, вид сверху.FIG. 1 shows a cultivator for treating stony and rubbly soils, side view; in fig. 2 - the same, top view.

Культиватор состоит из рамы I, имеющей р д поперечных брусьев 2-4, рабочих органов 5, установленных в средней части заднего звеньев 6 шарнирных четырехзвенников 7, продольные т ги 8 которого выполнены с консол ми 9, взаимодействующими 20 с позади расположенным поперечным брусом 3 или 4. Культиватор снабжен также ограничителем 10 глубины обработки.The cultivator consists of a frame I, having a number of transverse bars 2–4, working bodies 5, installed in the middle part of the rear links 6 of hinged four-eaves 7, longitudinal bars 8 of which are made with brackets 9, interacting 20 with a rear-mounted transverse bar 3 or 4. The cultivator is also equipped with a limiter 10 of the depth of processing.

Claims

The cultivator works as follows. When moving along the field, the working bodies 5 are buried in the soil, loosening it and cutting the weeds. When meeting with the obstacle due to the occurrence of lateral force working body 5 is turned off in one direction or another, moving in the horizontal plane the rear link 6 and the longitudinal thrust 8 of the hinge four link nick 7, while the toe of the working body 5 is automatically installed in the direction of movement, thus achieving high quality processing . Due to the interaction of the cantilevers 9 with the rear crossbar 3 or 4 located behind, additional support is provided to the links of the four-tiered 7, which results in high rigidity and, therefore, reliability of the cultivator design. The proposed cultivator for the treatment of stony and stony soils makes it possible to radically improve the quality of work and increase the reliability of its design. The economic effect of introducing the invention C (; sets 1000 per year. Claims of the invention A cultivator for processing stony and rubbly soils, including a frame with a crossbar and working bodies attached to it by means of horizontally mounted jointed four-links with front and rear links connected by longitudinal drags, characterized in that, in order to increase the reliability of the design, the frame has an additional transverse beam, which is located behind the main one, and the longitudinal traction of four-link mechanisms Completed with the console to interact with behind the transverse beam, and the working body is located in the middle part of the rear link.
