Description

The device relates to the field of logging, namely, logging machines. Forest harvester can be used both in the felling-delimbing-and-cutting device mode when working with standing trees, and in the loader mode when working with assortments laid on the ground.

A known design of a felling and skidding processor machine [Description of the patent for utility model RU 94111, priority dated 12/02/2009, published 05/20/2010], which includes a base machine with a platform mounted on it with a clamping cone and a manipulator, including an arrow and handle. A harvester head is installed on the handle of the manipulator as a load-gripping organ, intended for use as a gripping-cutting and processor device.

A disadvantage of the known felling-skidding and processing machine is its insufficient productivity when disassembling a stack of logs stacked in a pile on the ground, which is caused by the inconvenience of work, since the jaws of the harvester head are not adapted to perform this operation and there is no possibility to develop sufficient effort to implement them into a pack of trees, since the harvester head pivotally connected to the handle rotates freely on the suspension.

Known manipulator with uncoupler stacks of logs [Description of the patent for utility model RU 163761, decl. 10/27/2015; publ. 08/10/2016], connected via a swivel connection to a rotary column mounted on the base machine, comprising an arrow, a handle articulated by a swivel connection with an arrow, a working body and a disconnector mounted on the handle, a control system including hydraulic boom drive cylinders, a handle hydraulic cylinder, hydraulic cylinder drive the working body, the disconnector hydraulic cylinder. In the known construction of a manipulator with a disconnector of a stack of logs, the disconnector is made in the form of a beam, pivotally attached to the end of the handle, at one end of which a working body is pivotally mounted, for example, a harvester head, and the other is made in the form of a pointed rod.

A disadvantage of the known manipulator with a disconnector of a stack of logs is the lack of productivity when disassembling a stack of logs stacked in a stack on the ground, which is caused by the inconvenience of working due to the fact that the jaws of the harvester head are not sufficiently adapted to perform this operation and, in addition, it is not possible to develop sufficient effort to implement them in a pack of trees, since the harvester head pivotally connected to the handle rotates freely on the suspension, and the disconnector allows you to only expand the logs relative to each other and does not have the functionality of capture and controlled lifting of timber.

The closest in nature and taken as a prototype is the well-known construction of a harvester with a bucket-beam, which allows to perform a number of additional functions, for example, uprooting stumps [Harvester Doosan. - Electronic resource. - Access mode: http://www.doosan-infracore.ru/articles/322/ (accessed: 06/28/2017)]. The well-known harvester with a bucket-beam includes a basic self-propelled chassis, which is used as a crawler excavator, a manipulator containing an arrow, a handle, articulated by an articulation with an arrow, articulated with a beam beam. A harvester head is pivotally attached to one end of the beam, and a bucket is fixedly attached to the opposite end.

A disadvantage of the well-known harvester with a bucket-beam is insufficient productivity when parsing a stack of logs stacked in a pile on the ground, which is caused by the inconvenience of working due to the fact that the jaws of the harvester head are not adapted to perform this operation and there is no possibility to develop sufficient effort to implement them in a pack of trees, since the harvester head pivotally connected to the handle rotates freely on the suspension, and the bucket does not have the grab functionality and we control of hoisting round timber.

The technical result of the proposed forest harvester is to increase the productivity of work associated with disassembling a stack of assortments stacked on the ground, reducing the likelihood of damage to the harvester head during relocation operations with assortments located on the ground.

The technical result is achieved by the fact that on the forest harvester, including the basic self-propelled chassis, a manipulator comprising an arrow, a handle articulated by an articulation with an arrow, a rocker arm pivotally connected to the arrow is mounted at one end of which a harvester head is mounted, at the opposite end of the rocker arm, a jaw tick-shaped clamshell grab.

In FIG. 1 shows the proposed forest harvester with the harvester head in working position. In FIG. 2 presents the proposed forest harvester in the working position of the jaw tick-shaped grab.

The proposed forest harvester includes a basic self-propelled chassis 9 with a mounted manipulator. The manipulator includes an arrow 3, articulated by means of a swivel joint 4 with a handle 5. At the end of the handle 5 by means of a swivel joint 16 a rocker 8 is fixed.

The manipulator can be mounted on a turntable (not shown in Fig.) Of a self-propelled chassis 9 or by means of a swivel joint 1 on a rotary column 2.

A harvester head 7 is pivotally mounted at one end of the rocker arm 8, and a jaw-like clamshell grab 18 is pivotally fixed at the opposite end of the rocker arm 8. Due to the presence of the articulated joint 16 and the hydraulic cylinder 13, the rocker arm 8 can be brought into working position by turning in the articulated joint 6 relative to the handle 5 harvester head 7 (Fig. 1) or maxillary tick-shaped clamshell grab 18 (Fig. 2).

If it is necessary to use a harvester head (felling, cutting of branches, bucking), the beam 8 is located along the handle 5 so that the part of the beam 8 on which the harvester head 7 is mounted is a continuation of the handle 5.

If you need to use the jaw tick-shaped grab grab 18 (moving operations), the rocker arm 8, turning in a swivel joint 16, becomes at an angle to the handle 5, abutting against the stop 17.

Each link of the proposed forest harvester, namely the boom 3, the handle 5, the rocker 8, are equipped with individual hydraulic cylinders 11, 12, 13, respectively. The harvester head 7, having jaws 15, is equipped with an individual hydraulic actuator 14, which ensures its functioning. The maxillary tick-shaped grab grab 18 also has its own individual hydraulic drive 19.

The management of the proposed forest harvester is carried out through a management system located at the operator’s workplace.

The proposed forest harvester works as follows. The operator of the base machine 9, by means of control equipment located at its workplace, puts the harvester head 7 into operation, controlling the operation of the harvester head 7 (Fig. 1) conducts operations of felling, trimming knots, bucking, laying cleared assortments 10 on the ground in stacks with sorting by breed and size. The relative movement of the individual parts of the boom 3, the handle 5, the harvester head 7 of the proposed forest harvester is provided due to their articulated joints 1, 4, 6 with each other.

If it is necessary to move the assortments located on the ground, to dismantle the assortment stack 10, the operator, by means of control equipment, acting on the hydraulic cylinder 13, puts the jaw-like clamshell grab 18 into working position (Fig. 2). Next, the operator using the jaw tick-shaped clamshell grab 18 performs the necessary moving operations with assortments 10.

Thus, the use of the proposed forest harvester will simplify the operations of selecting and moving assortments located on the ground, dismantling a stack of assortments, as well as increase the productivity of these works.

Forest harvester can be used both in the felling-delimbing-and-cutting device mode when working with standing trees, and in the loader mode when working with assortments laid on the ground. Since the jaws of the harvester head are not sufficiently adapted to capture individual assortments from the stack, and in addition there is no way to develop sufficient force to introduce them into the stack of assortments, due to the fact that the harvester head rotates freely on the suspension, the use of the jaw-like grab grapple grapple of the proposed forest harvester will greatly simplify the process parsing stacks of assortments.

In view of the insufficient adaptability of the harvester head to grab assortments from the stack, the probability of damage to an expensive harvester head during this type of work is high. The use of a jaw tick-shaped grab grapple more suitable for this purpose will increase the productivity of work related to disassembling assortments stacked in a pile on the ground and reduce the likelihood of damage to the harvester head during moving operations with assortments located on the ground.
