Supporting-rotating apparatus

FIELD: forestry, in particular, processing apparatuses for tree harvesting machine used in tree felling and bunching equipment.

SUBSTANCE: supporting-rotating apparatus has base and rotary platform between which are positioned three rotating wheels and two intermediate members, said intermediate members being mounted between rotating wheels. Central brake is installed on rotary platform and is cooperating with base through joining link which is connected with its upper end through Hooke's universal joint and central brake to rotary platform and with its lower end through the same Hooke's universal joint to base. Link is adapted for changing its length by means of, for example, splined joint. Intermediate and lower rotary wheels are equipped with brakes. Intermediate rotary wheel brake is mounted on upper intermediate member. Lower rotary wheel brake is mounted on lower intermediate member. Rotary wheels are arranged at an angle with respect to each other. On rotation of rotary platform, rotation mechanism cooperates with one of rotary wheels. During operation on slopes, individual members of apparatus are rotated to thereby level rotary platform until it is rotated and set in horizontal plane.

EFFECT: increased efficiency by employing machine for felling and bunching trees on uneven felling areas and on slopes, reduced labor intensity, and provision for creating comfortable working conditions for operators.

The invention relates to the technical equipment harvesting machinery used for felling and bunching trees, perceiving this large eccentric load, and can be used in the forest industry.

Known rotation device in the form of a circle that includes gear in constant engagement with a gear mechanism to rotate the turntable, the top and bottom of the cage, the rollers (Feller-Bunchers machine PL-19. Circles B.C., Barman M.A., Ermolaev VP, Queens, V.E., Popov BV): genre differences. prom the terrain, 1982. - 288 S., see p.20, Fig. 9).

The disadvantage of this turntable is that it is not possible to align the turntable while the machine is on a slope, thereby increases the number of transfers to perform gripping and cutting, resulting in a decrease in performance.

Closest to the invention is a rotation device, includes a base, two turntable set at an angle to each other and one above the other, the lower range is set on the base, and the top - mounted rotary platform, an intermediate element mounted between the turning circles and turning mechanism turntable with a Central brake (Misurkin PM - Search konstruirovanie the forestry equipment. - Moscow: publishing house of Saratov University. Saransk branch, 1990, see pp. 80-81, Fig. 36). The disadvantage of this turntable is that it is not possible to set the turntable in a horizontal plane when the machine is in operation on slopes.

To address these shortcomings, the proposed construction of a turntable comprising a base, two turntable set at an angle to each other and one above the other, the lower range is set on the Foundation and installed on the upper rotary platform, an intermediate element mounted between the turning circles and turning mechanism with Central brake, turntable, between the base and the turntable has three turntable and two intermediate element mounted between the rotary community, Central brake, mounted on the rotary platform and cooperating with the base via a connecting element, which is connected to the top end through a hinge Hooke and Central brake with turntable and the lower end through the same hinge gook with the base, while the connecting element is designed with the ability to change its length, for example using a flat-blade connection, brakes middle and lower turning circles, while the brake medium rotation of the second circle is installed on top of the intermediate element, and brake the bottom of the turntable on the bottom of the intermediate element, a turntable mounted at an angle to each other, and the rotation mechanism when rotating turntable interacts with one of the swivel wheels.

The proposed construction of a turntable allows you to set the turntable in a horizontal position when the machine is in operation on virtually any terrain and slopes, which increases the efficiency of operation of the machine, which is equipped with such a device, and the comfort of the operator.

In the patent and scientific literature is similar to the design of a turntable we have not identified.

The drawing shows the rotation device, the cut. Rotation device includes a base 1 on which is rigidly mounted the lower part 2 of the lower turntable 3 with a ring gear 4. On top of the bottom 5 of the turntable 3 is rigidly fixed to the intermediate element 6, which is fixed to rotary part of the brake 7 and the gear 8 of the brake 7 is engaged with the ring gear 4. On top of the intermediate element 6 is rigidly fixed to the lower part 9 of the intermediate turntable 10 with a ring gear 11, the upper portion 12 intermediate the turntable 10 is rigidly installed promezhutochnye 13, installed the brake 14 intermediate the turntable 10, the gear 15 which is in mesh with a ring gear 11. On the upper part of the intermediate element 13 is set lower portion 16 of the upper turntable 17 with a ring gear 18. On the top of the rotating part 19 of the upper turntable 17 is installed rigidly rotating platform 20 with the technological equipment (not shown). On the rotary platform 20 has a rotation mechanism 21 of the platform 20 and the Central brake 22. On the output shaft 23 of the rotation mechanism 21 is fixed leading gear 24 which is engaged with a ring gear 18. Central brake 22 is connected by a link 25 with the base 1 via hinges gook 26. The link 25 is arranged to change its length, for example, using the spline 27.

Rotation device operates as follows.

Before leveling (leveling) turntable 20, when stationary on a slope, the operator slows the Central brake 22 and the brake 14 intermediate the turntable 10, restorative brake 7 the bottom of the turntable 3. After that, the operator includes a rotation mechanism 21 and begins to rotate the design, while in a position intermediate the turntable 10 and he restorative his brake 14, but magevet brake 7 the bottom of the turntable 3 and further rotation produces the alignment of the turntable 20. For connection of the Central brake 22 and the base 1 is used connecting link 25, is arranged to change its length, for example, using the spline 27 and attached through hinges gook 26. Next to perform full turns of the turntable 20, the operator slows brakes 7 and 14 and restorative Central brake 22.

Application of the proposed design of a turntable will allow more efficient use of the machine, and the work of the operators will be more convenient.

FIELD: forestry, in particular, processing of individual trees, may be used for cleaning cutting in average aged and ripening stand.

SUBSTANCE: method involves processing tree by initially cutting branches from the bottom to the top of tree over trunk up to crown part; upon removal of crown part, leaving trunk for several months to provide for natural drying of tree trunk. Method allows versatility of felling-bunching machine with gripping-and-cutting boom to be increased and operational capabilities of machine to be widened owing to adaptation to different kinds of tree and stand care processes. It means that single machine may be used for tree clear or selection felling processes, as well as for caring of crown of individual trees. Method may be effectively used for caring of trees in parks, gardens and preservation plots by means of existing felling-bundling machines furnished with small-sized gripping-cutting booms having maximal predetermined weight and load capacity.

EFFECT: increased efficiency and wider operational capabilities.
