RU2492628C1 - Method of operation of feller-delimber-bucker - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: method comprises gripping the standing tree with the working head of the feller-delimber-bucker, tree felling, limbing and cross-cutting of the gripped tree with creation of assortments on the felling area. In creation of assortments they are sorted by machine to assortments with barrel-butted feature and assortments with normal taper, putting assortments in separate piles. After processing all the trees of the site in the area of radius of the machine manipulator the operation of cylindering the assortments with barrel-butted feature is started, removing it. Cylindering the assortments with barrel-butted feature is performed by the cutting body built-in in the working head of the feller-delimber-bucker, at that the assortment with barrel-butted feature is rotated about its longitudinal axis, moving it along it.

EFFECT: method enables to increase the travelling load of logging truck-and-trailer units, which can increase the productivity of the process of logging.

Description

There is a method of operation of a feller-delimbing-and-cutting machine with a working head, including grabbing a standing tree with the working head of a feller-delimbing-and-cutting machine (HSRM), felling, pruning, and bucking of a captured tree with producing assortments [1]. With the existing method, the preparation of round timber with a stickiness for skidding and hauling logs and timber trucks is not provided, because of which packs of logs loaded on log platforms and log trucks have low full wood, which significantly reduces their log load, and, as a result, productivity .

There is also known a method of cylindrical round timber with bobbing in special woodlands, after skidding and hauling [2]. The processing of round timber with intergrowing occurs with the help of several mills on a massive bed using powerful electric motors and gearboxes. The inability to use this equipment in a suspended version and the possibility of use only in large stationary enterprises narrows the scope of this device. Also, the need to sort the trees (assortments) and pass the entire flow of round timber through the mechanism for processing round timber with barking sharply increases the processing time of one sortment, which reduces the productivity of the entire line. Also, in the proposed method, the processing of round timber with a stickiness in the timber store is performed, which does not give a positive effect when transporting the processed logs.

There is also known a method of cylindrical round timber with a hardening by a special mobile device [3]. The disadvantages of this method are related to the need for additional equipment, which requires a special tractor. In the mobile version of the application of the device in the technological process, idling is necessary for processing the opposite side of the butt, this significantly increases the time spent on processing. The device of the cutting mechanism limits the range of diameters of trees available for processing, and is not suitable for loading. When using the device high energy intensity of the process and financial costs. In addition, moving such a device through the cutting area after the VCRM operation will sharply increase the number of passes of vehicles along the same technological corridors, which sharply worsens the properties of soils in the technological corridors.

The technical result, the achievement of which the claimed method is aimed, is to increase the coefficient of full wood and, accordingly, the running load of the sortimentovoz used for the subsequent removal of assortments from the cutting area and, as a result, to increase its productivity. Bringing agglomerated assortments to normal growth rates in the cutting area will reduce subsequent costs when developing sawn products from these assortments.

The technical result is achieved due to the fact that, when developing assortments, they are sorted into assorted assorted and assorted assorted assortments, stacked in separate stacks, and after processing all the trees from the parking lot in the departure area of the manipulator, they start the operation of sorting assortments with entrapment, removing it, moreover, the cylindering of assortments with staggering is carried out by a cutting body mounted in the working head of the feller-delimbing-cutting machine, while the assortment with staggering is rotated around its longitudinal axis, moving it along it.

Figure 1 shows the technological process of developing cutting areas with the use of HSRM for stubborn round timber. In the apiary 4, the HSRM 1 produces felling of tree 6, pruning of branches and bucking of wood into assortments. From one parking lot, the HSRM makes felling of trees located in the reach of the boom of the manipulator 3. When bucking the tree 6, the resulting assortments are put in a separate pile 7 by turning the working head 2. The assortments with normal run are stacked when bucking in the stack 8. After processing all trees from the parking lot in the relegation zone of the manipulator begin the operation of cylindering assortments with a stiffness, removing it, and the cylindering of assortments with staggering is performed by a cutting body mounted into the working head of the feller-delimbing-and-slaughtering machine, while the assortments are rotated around their longitudinal axis with agility, moving it along it.

The method of operation is carried out by a feller-delimbing-and-cutting machine 1 with a working head 2 located at the end of the manipulator 3. The method is implemented as follows. The HSRM moves along technological corridor 4 in the cutting area 5. At each parking lot, the HSRM sequentially processes trees located in the area of operation of the manipulator 3.

The method includes grabbing a standing tree 6 with a working head 2 of a felling-delimbing-cutting machine 1, felling a tree, cutting branches and bucking of a captured tree with producing assortments on a cutting area, characterized in that when sorting out assortments, they are sorted into assortments with a fineness of 7 and assortments with a normal run of 8, stacking them in separate stacks, and after processing all the trees from the parking lot in the departure zone of the manipulator 3, they start the operation of cylindering assortments with a bobbin, removing it, and cylindering of cr glyh timber with zakomelistostyu perform cutting body built-in operating head felling and delimbing and raskryazhevochnoy machine by turning assortments zakomelistostyu to rotate around its longitudinal axis, moving it along it.

With the existing method, round timber is prepared with a stickiness for skidding and haulage of sorting trucks and timber trucks, due to which packs loaded on logging and timber truck platforms increase full wood growth by 10-15%, which increases their route load, and, as a result, performance. This method allows you to add an additional operation on the butt cylinders to the HRMP process, this will equalize the performance of the HRMP and the forwarder, which will reduce downtime when applying this workpiece technology.
