Изобретение относитс к сельскохоз йственному машиностроению, в частности к устройствам дл стрижки живых изгородей.The invention relates to agricultural machinery, in particular to devices for trimming hedges.

Известен режущий аппарат дл контурной обрезки деревьев, содержащий установленные на раме вращающиес вокруг общей оси навстречу друг другу режущий, и противорежущий ножи, причем лезвие противорежущего ножа выполнено по вогнутой кривой , а лезвие режущего - по выпуклой 1.A cutting machine for contour pruning of trees is known, which contains cutting and rotating knives mounted around a common axis facing each other, and cutting knives, the blade of the cutting knife is made along a concave curve, and the cutting blade is convex 1.

Недостатками известного аппарата вл ютс сложность изготовлени и периодической заточки режущих элементов в св зи с наличием кривых кромок и повыщенна металлоемкость.The disadvantages of the known apparatus are the difficulty of manufacturing and periodic sharpening of the cutting elements in connection with the presence of curved edges and increased metal intensity.

Известен режущий аппарат, содержащий установленные с перекрытием дисковые ножи и механизм привода. Дисковые ножи в этом аппарате попарно вращаютс навстречу друг другу и резание происходит в створе этих дисковых пар, а подача материала от периферии каждой пары в створ осуществл етс за счет трени дисков о перерезаемые стебли 2.Known cutting apparatus containing installed with overlapping circular knives and a drive mechanism. The disk knives in this apparatus rotate in pairs towards each other and cutting takes place in the alignment of these disk pairs, and the material is fed from the periphery of each pair to the target by rubbing the discs on the cut stems 2.

Недостатками данного аппарата вл етс ограниченна область применени и плохое качество обрезки, так как они могут резать только тонкостебельные, редко расположенные побеги, имеющие малое сопротивление кусту, а также необходимость больщкх скоростей резани , что ведет к увеличению диаметра дисков или к повыщению 5 частоты их вращени , а это или увеличивает габариты аппарата, или создает опасность дл обслуживающего персонала и вызывает быстрый износ трущихс поверхностей.The disadvantages of this device are the limited scope and poor quality of pruning, since they can only cut thin stem, rarely located shoots that have little resistance to the bush, as well as the need for high cutting speeds, which leads to an increase in the diameter of the discs or to an increase in the frequency of their rotation. , and this either increases the size of the apparatus, or creates a danger to the staff and causes rapid wear of the rubbing surfaces.

Цель изобретени - улучшение качество на обрезки живых изгородей с различной толщиной ветвей.The purpose of the invention is to improve the quality of trimming hedgerows with different branches thickness.

Указанна цель достигаетс тем, что дисковые ножи снабжены закрепленными жестко на их боковых плоскост х радиальными пальцами, концы которых выступают за 15 режущую кромку ножей, причем пальцы смежных дисков установлены с угловым смещением относительно друг друга. This goal is achieved by the fact that the circular knives are provided with radial fingers fixed rigidly on their lateral planes, the ends of which protrude beyond the 15 cutting edge of the knives, and the fingers of adjacent disks are installed with an angular displacement relative to each other.

Claims

FIG. 1 shows a cutting apparatus, front view; in fig. 2 - the same, a type of failure in fig. 3 - the same view from the side of the drive mechanism; in fig. 4 - node I section. The cutting unit contains rotating disk knives 2 mounted on the frame 1, on which the fingers 3 are rigidly fixed. The disk knives 2 are firmly mounted on the shafts 4, and the driven sprockets 5 are firmly fixed on the other ends of the shafts, which together with the driving 6 and the tensioning 7 asterisks are covered endless chain 8. The operation of the cutting apparatus is as follows. In the process of working, the cutting apparatus has its body turned in the direction of the object being processed. With the help of an endless chain 8, the leading sprocket 6 rotates the sprocket 5, which are rigidly connected to the disk blades 2. In this case, the disk blades begin to rotate towards each other. In the process of translational motion, the fingers 3, rotating with the disk knives 2, alternately in each pair capture the material being cut and feed it into the target of two disk knives, where the pinching and cutting occur. After cutting, the cut shoots are thrown back, giving way to the next one. The application of the proposed cutting apparatus allows high-quality cutting operations to be performed as thin stem. and coarse-grained crops. The apparatus is simple in construction and simple to manufacture and operate. Claims Cutting apparatus for hedgerows containing disk knives mounted on a frame with overlapping and a drive mechanism, characterized in that, in order to improve the quality of trimming hedges with different branch thicknesses, the circular knives are fitted with rigidly fixed radial fingers on their lateral planes The ends of which protrude beyond the cutting edge of the knives, and the fingers of the adjacent disks are mounted with an angular displacement relative to each other.
