изобретение относитс к лесной промышленности , в частности к механизмам дл корчевки пней.The invention relates to the forest industry, in particular to mechanisms for stump removal.

известно устройство дл корчевки пней, включаюш:ее силовую раму с домкратами и грузовую раму с вибратором и челюстным захватом 1.A device for stump removal is known, including: its load frame with jacks and a load frame with a vibrator and jaw grip 1.

известно также устройство дл корчевки пней, включаюш.ее силовую раму с шарнирной подвеской и домкратами и грузовую раму с вибратором, челюстным захватом и приводом захвата 2.Also known is a device for rooting stumps, including a power frame with articulated suspension and jacks and a cargo frame with a vibrator, jaw grip and a grip drive 2.

Недостатком известных устройств вл етс недостаточна эффективность в работе .A disadvantage of the known devices is the lack of efficiency in operation.

Цель изобретени - повышение производительности .The purpose of the invention is to increase productivity.

Поставленна цель достигаетс тем, что грузова рама св зана с силовой посредством шарнира, ось которого расположена вертикально, и снабжена приводом поворота относительно силовой рамы.The goal is achieved by the fact that the load frame is connected to the power frame by means of a hinge, the axis of which is located vertically and is equipped with a rotational drive relative to the power frame.

На фиг. 1 изображено устройство дл корчевани пней, обш,ий вид; на фиг. 2 - то же, вид сверху; на фиг. 3 - механизм поворота несущей оси.FIG. 1 shows a stump grubbing device, sheath, view; in fig. 2 - the same, top view; in fig. 3 - the mechanism of rotation of the bearing axis.

Устройство включает силовую раму 1, котора навешена на стреле 2 посредством шарнирной подвески симметрично относительно вертикальной геометрической оси, проход шей через место подвеса. Причем - подвеска выполнена с возможностью поворота силовой рамы 1 вокруг этой оси. Така подвеска может быть осуществлена, например , посредством двух пар серег 3, одна из которых шарнирно закреплена на стреле 2, а друга - 4 на арке 5 силовой рамы 1.The device includes a power frame 1, which is hinged on the boom 2 by means of an articulated suspension symmetrically with respect to the vertical geometric axis, passing through the suspension point. Moreover, the suspension is made with the possibility of rotation of the power frame 1 around this axis. Such a suspension can be carried out, for example, by means of two pairs of earrings 3, one of which is hinged on the boom 2, and the other - 4 on the arch 5 of the force frame 1.

0 Серьги каждой из пар св заны между собой жесткими звень ми, в частности, серьги пары 3 св заны звеном 6, а серьги пары 4 - звеном 7. Звень 6 и 7 одеты с возможностью свободного поворота друг относительно друга на общей оси 8, размещенной0 The earrings of each of the pairs are connected to each other by rigid links, in particular, the earrings of the pair 3 are connected by link 6, and the earrings of the pair 4 are connected by link 7. Link 6 and 7 are dressed with the possibility of free rotation relative to each other on a common axis 8 placed

5 вдоль вертикальной геометрической оси, проход щей через место подвеса силовой рамы 1 На силовой раме I жестко, диаметрально противоположно закреплены гидродомкраты 9 с опорными пластинами 10. Устройство5 along the vertical geometric axis passing through the suspension frame of the power frame 1 On the power frame I, hydraulic jacks 9 are rigidly diametrically opposed with support plates 10. The device

also equipped with a cargo frame, made in the form of a housing 11, inside which a vibrator 12 is mounted. In the eyes of the housing 11, jaws 13 of a mon are mounted symmetrically, which can be rotated by means of a hydraulic cylinder 14. The load frame is connected to the force one by means of an axis 15 located along the vertical geometrical axis passing through the suspension location of the power frame 1. The axis 15 with its lower end is fixedly mounted on the housing 11, and the upper end is mounted on the power frame 1 with the possibility of rotation around its axis A rotary mechanism consisting of a hydraulic cylinder 16, the casing of which is hinged on the power frame 1, and hingedly connected to each other, as well as the rod of the hydraulic cylinder 16 and the axle 15 of the sections 17. Between the axle 15 and the power frame there are mounted flat springs 18. The device Operates as follows: 2 handlers The device is pointed at a stump. At the same time, through the hydraulic cylinder 16 through the rotary mechanism sections 17, the operator rotates the axle 15 and the load frame rigidly connected with it with the jaws 13 of the gripper mon so that the jaws are positioned between the side-roots of the projecting above the ground mon. Further, by an arrow 2, the device is lowered to the ground, by means of hydraulic cylinders 14, jaws 13 are inserted under a stump. The hydraulic jacks 9 are then turned on and the extraction process begins. In the event that the adhesion force of the roots of the mon to the ground turns out to be higher than the force developed by the hydraulic jacks 9 when it is applied at selected points, the operator, without returning to the initial position of the jaw 13, switches on the hydraulic cylinder 16, which, through sections 17, causes the force frame to turn 1, relative to the weight associated with the stump, and thereby alters the points of application of the uprooting force. If the jaws 13 have got to the roots of the first order and the grip cannot penetrate the ground and capture the stump well, then by moving the jacks 9 with frame 1 to a new position, you can also move the jaws 13 to a new position and firmly grip the stump. After that, the jacks are turned on again 9. If the pulling force overcomes the cohesive forces of the roots of the mon, the latter is removed from the ground. Further, by an arrow 2, the stump rises above the ground and, by means of the vibrator 12, detaches itself from the ground and rot. Then, by an arrow 2, the stump is guided to the storage location or into the vehicle body, where, by means of hydraulic cylinders 14, the jaws 13 are opened and the stump falls. Then the cycle repeats. By providing the device with the ability to rotate the jaws of the grip relative to the force frame when aiming at the stump and the power frame itself relative to the jaws with the stump clamped in it before removing the latter from the ground, the technological capabilities of the device increase significantly, which allows to increase the productivity and, consequently, AND efficiency when stumping . Claims device for stubbing, including a power frame with articulated suspension and jacks and a cargo frame with a vibrator, jaw grip and drive gripper, characterized in that, in order to improve performance, the cargo frame is connected to the power frame by means of a hinge, whose axis is located vertically , and equipped with a rotational drive relative to the power frame.
