Изобретение относитс к лесной промьшшенности, в частности, к оборудованию по обрезке сучьев и хлыстов.FIELD OF THE INVENTION The invention relates to the forest industry, in particular, to equipment for pruning branches and whips.

Известна сучкорезна головка, состо ща из основани , неподвижного и боковых силовых ножей и привода 1 .Known delft head, consisting of a base, fixed and lateral power knives and a drive 1.

Известна также сучкорезна головка , включающа основание со смонтированным на нем нижним неподвижным и боковыми криволинейными ножами, установленными шарнирно на поворотных рычагах, св занных с приводом 2J.Also known is the thrust head, which includes the base with the lower fixed and side curvilinear knives mounted on it, which are hingedly mounted on the pivoting levers associated with the 2J drive.

Недостатком известных устройств вл етс низкое качество обрезки сучьев .A disadvantage of the known devices is the low quality of pruning.

Цель изобретени - повышение качества обрезки сучьев.The purpose of the invention is to improve the quality of pruning.

Указанна цель достигаетс тем, что один из концов каждого бокового криволинейного ножа кинематически св зан с поворотным рычагом посредством т г и поводка,, который свободно установлен на оси поворотного рычагаThis goal is achieved by the fact that one of the ends of each side curvilinear knife is kinematically connected with a pivot arm by means of a pull and a lead, which is freely mounted on the pivot arm axis

На фиг.1 изображена схема сучкорезной головки при большом диаметре ствола дерева, вид спереди; на фиг.2 то же, при малом диаметре ствола дерева; на фиг.З - схема бокового криволинейного ножа.Figure 1 shows a diagram of the delimbing head with a large diameter of the tree trunk, front view; in figure 2 the same, with a small diameter of the trunk of a tree; on fig.Z - side curvilinear knife.

Сучкорезна головка состоит из основании 1, поворотных рычагов 2, с noMOtiibro оси 3 укрепленных на нем, боковых криволинейных ножей 4, с помощью шарнира 5 укрепленных на поворотных рычагах 2, т г б, шарнирно соединенных , одним концом с нижними концами ножей 4, а другим - с поводком 7, и упоров 8, неподвижно установленных на основании.The locking head consists of a base 1, pivot arms 2, with noMOtiibro axis 3 fortified on it, side curvilinear knives 4, with a hinge 5 fortified on pivoting levers 2 others - with a leash 7, and stops 8, fixedly mounted on the base.

Внутри основани размещен силовой привод поворотных рычагов 2, включающий рычаги 9, укрепленные на ос х 3 поворотных {Алчагов и соединенные шар5 нирно с гидроцилиндрами 10, размещенными внутри пружин 11.Inside the base there is a power drive of the pivot arms 2, which includes levers 9, mounted on axles 3 rotary {Alchagov and connected ball with hydraulic cylinders 10 placed inside the springs 11.

Сучкорезна головка работает следующим .образом.Succore head works as follows.

Дерево закладываетс в сучкОреэную головку, переключением золотника на прижим ножей 4 под действием пружин 11 поворотные рычаги 2 прижимают ножи 4 к стволу.The tree is laid in the knot of the head, by switching the spool to the pressing of the knives 4 under the action of the springs 11, the swivel arms 2 press the knives 4 to the trunk.

Claims

When the knives 4 are fitted with a large bore due to the fact that the axis of the hinged joint of the knife with the pivot arm is located above the axis of symmetry of the smaller arc of the curvilinear knife, the force of pressing it evenly 0 is distributed to the points of contact. As the diameter of the barrel decreases, the ends of the knives 4, acting on the rods 6, turn the drivers 7 towards the stops 8. When a certain diameter is reached, the drivers 7 abut against the stops 8, forming a rotary lever system - pulling the leash / articulated four-link. providing a predetermined path of the knife 4 at medium and small diameters and copying these diameters by a section of a curved knife with a smaller arc of curvature, and the axis of symmetry of this arc passes through the centers of the diameters of the stems. At the end of the wood treatment, the supply of fluid to the rod cavity of the hydraulic cylinders 10 causes the springs 11 to be compressed and the blades driven once, after which the cycle is repeated. Claims. Twisting head including base with lower fixed and side curvilinear knives mounted on it, pivotally mounted on pivoting levers connected to the drive, which THAT, to improve the quality of knitting of knots, one end of each side curvilinear knife is kinematically associated with a pivot arm through the tg and a leash, which is freely mounted on the axis of the pivot arm.
