Description

Изобретение относитс к сельскому хоз йству и может быть использовано дл очистки дикорастущих зарослей полукустарников анабазиса на больших массивах.The invention relates to agriculture and can be used for cleaning wild-growing thickets of anabasis semi-shrubs on large tracts.

Известно устройство дл срезани кустарников и полукустарников, содержащее раму с двум расположенными под углом друг к другу отвалами, на нижних кромках которых смонтированы ножи 1.A device for cutting off shrubs and semi-shrubs is known, comprising a frame with two dumps arranged at an angle to each other, on the lower edges of which the knives 1 are mounted.

Недостатками известного устройства вл ютс низкое качество обрезки дикорастущих зарослей и повреждение пахотного сло на уровне корневых шеек .The disadvantages of the known device are the low quality of pruning of wild-growing thickets and damage to the arable layer at the level of the root neck.

Целью изобретени вл етс повышение боковой устойчивости, а также обеспечение качественного среза на неровной и ровной поверхност х.The aim of the invention is to increase the lateral stability, as well as to ensure a high-quality cut on uneven and even surfaces.

Поставленна цель достигаетс тем, что в предложенном устройстве на задних поверхност х отвалов закреплены упорные.ножи. При срезе на неровной поверхности отвалы выполнены под углом 60-70 друг к другу, а при срезе на ровной поверхности - под углом 80-90° друг к другу.The goal is achieved by the fact that, in the proposed device, there are fixed foot rests on the rear surfaces of the dumps. When cut on an uneven surface, the dumps are made at an angle of 60-70 to each other, and when cut on a flat surface - at an angle of 80-90 ° to each other.

Устройство состоит из рамы 1, ножей 2 с отвалами 3, закрепленных на раме, и распорных балок 4, установленных внутри рамы. Отвалы выполнены под углом 60-70 друг к другу дл неровной поверхности и под углом 8090 дл ровной.The device consists of a frame 1, knives 2 with dumps 3 mounted on the frame and spacer beams 4 installed inside the frame. The dumps are made at an angle of 60-70 to each other for an uneven surface and at an angle of 8090 for a level.

Устройство снабжено упорными ножами 5, закрепленными на задних поверхност х отвалов 3, щиками 6, размещенными на распорных балках, соединительной балкой 7, к которой прикреплена рама. Упорные ножи прикреплены к отвалам с помощью шпилек 8 с гайками.The device is equipped with resistant blades 5, mounted on the rear surfaces of the dumps 3, with boxes 6 placed on the expansion beams, with a connecting beam 7 to which the frame is attached. Thrust knives are attached to the dumps with the help of 8 studs with nuts.

Устройство работает следуквдим образом .The device works in the following way.

Claims

Dumps 3 with knives 2 are set at an angle to each other, equal to 60-70 or 80-90 °. Angle is selected when cutting the array, depending on the terrain. Then, frame 1 is attached to the vehicle (not shown in the drawing) by means of a connecting beam 7, which, when moving, cuts stiff stalks at the level of the root necks. When dvik n move Ln Р ° STABILITY from the shafts during cutting is provided with two Up-5 knives, with the force of the stop N - iL. e de T - tractor traction force, kg; l is the shoulder to the axis of the gi from the place of cutting of the plant, cm; N is the force of the knife stop, kg; t - shoulder (cm) to the shoulder of force p (stocks c, see. Cutting quality is regulated by the load of ballasts of boxes 6. Sand can be used as a ballast. The proposed device allows improving the quality of cutting and eliminating damage to the topsoil at the level of root necks Claim 1. Device for cutting off shrubs and semi-shrubs, containing a frame with two dumps at an angle to one another, on the lower edges of which are mounted IlomS characterized in that in order to increase lateral stability P „GG - -. The device according to claim 1, in connection with the fact that, in order to ensure a high-quality cut, a pbd angle of 60-70 to one another is made on the non-curved ° BG70 ° ° 3. The device l, otlicha yu ee so that, in order to ensure a high-quality cut on a flat surface, the dumps are made at an angle of 80-90 to one another.Sources of information taken into account during the examination 1.
