Description

one

The invention relates to equipment for the mechanization of work on the debarking of logs.

HsiBecTHbi manual mechanized (debarking tools for logs, including body, cutting heads with drive and cutting depth guides.

However, these tools do not have sufficient performance "they do not only provide the required quality of bark; they are due to the fact that the cutting bodies are (they are made in the form of cutters that can not provide high quality debarking and remove bark on narrow bands). logs

The purpose of the invention is to increase the productivity and quality of debarking.

This is achieved by the fact that the tool body is made in the form of pivotally articulated and horizontally arranged cross-shaped levers, equipped with supporting rollers and carrying telescopic vertical stands, which are rotatably fixed at one end of the levers, the other ends of which are equipped (control knobs, and each cutting head made in a fluid mounted at the end of a tele-optical stand. flat spring-loaded jack cutters with overlapping cutting planes connected to the drive with the help of gear Gear and flexible drive shaft, and the depth of cut limiters are

adjustable rods with smooth rollers mounted in front of the slotting cutters mounted on the gearshift gears.

FIG. 1 shows a schematic representation of the proposed MANUAL mechanized tool, top view; in fig. 2 - the same, front view.

The manual mechanized tool INCLUDES the case, made in the form of levers 1 and 2, hinged .-; Between themselves articulated located in a horizontal plane. On some KOHiiax levers and 2, three telescopic vertical posts 4 are installed pivoting with the help of hinges, equipped with locking screws 5. At the other ends of the levers and two, there are control handles 6. The presence of the hinges 3 connecting the pillars 4 with the levers I and 2 enables log debarking from two opposite sides, for example, from the butt to the top and vice versa, by rotating the pillars 4 relative to the levers 1 and 2 by 180 °. For non-adherence; tooling along the trunk of the logs are provided the support rollers 7. Using the handle 6, it provides for a stable and easy feeding of the tool along the staol of the log for debarking. Cutting heads are installed on KOini.ax telescopic iCTOcii 4. Residiently gslov.kn contain case 8, in which in the order of the order with the help of radial-mounted valves installed

guides etulas 9 with slots. In sleeves 9, on a sliding fit, there is a splined shaft, 10 ki, which can rotate together with bushings and can simultaneously move along the longitudinal axes of the bushings. The rotational moment is transmitted to the guide bushes 9 through gear gears 11, which engage with the central gear gear 12. Gear 12 is driven to rotate from the central shaft 13. At the ends of the rods 10, spring-loaded elements 14 are fixed, which are nested milling cutters 15 with teeth on the bottom and side facets with cutting planes of cutting. In iKOpnyce 8 — against each nesting milling cutter 15, rods 16 are screwed in with smooth rollers 17 at the ends to control the depth of cut of the bark. The rotational moment of the cutters 15 is transmitted from the drive, by the engine from the chainsaw engine, with a flexible shaft 18 connected to the central shaft 13 of the gear drive of one of the cutting heads. To drive another reunion, a flexible shaft 19 is provided to it, which connects the central 1 shafts 13 of the gears of both cutting heads.

Manual mechanized tool for debarking logs works as follows.

The engine, for example, from a chainsaw, is connected to the central shaft 13 by means of a flexible shaft 18 and installed near the middle part of the circular log, so that the length of the flexible shaft is enough both to one end of the log and to the other.

Depending on the thickness of the bark to be removed, the depth of milling is set, for which the rods 16 with the rollers 17 are screwed or screwed into the body of the body 8.

Cutting heads establish the size of the log to be cut, for which they put forward

rack 4 in size logs and fixed with screws 5.

Using handles 6 and levers I and 2, the log is clamped between cutting heads and forward, leaning on the roller 7, the tool is rolled along the barrel, for example, from its upper cut to the shaft, the side of the barrel, the width of which is equal to the total cutter width 15 mounted on

each cutting head. After reaching the buttered log, the levers 1 and 2 of the body are rotated together with the cutting heads by 180 °, and the debarking of the log is made from the ends to the upper cut in the same order.

Subject and reference for 1I and

Manual power tool for

log debarking, which includes the body, cutting heads with the Drive, and depth of cut depth limiters, in order to increase the productivity and quality of the debarking, the tool body is designed as

articulated and horizontal cruciform arms, equipped with supporting rollers and supporting telescopic vertical posts, swivel mounted on one end of the arms, the other ends of which are equipped with control handles, and each cutting head is made in the form of flat, spring-loaded nested cutters mounted at the end of the telescopic rack with overlapping

cutting planes connected to the drive by means of gears and a flexible drive shaft, with the depth of cut limiters being mounted on gearing gear housings .adjustable rods with smooth rollers mounted on the outer side cutters.
