(5) ЛЕСОЗАГОТОВИТЕЛЬНАЯ МАШИНА(5) FORESTRY MACHINE

tt

Изобретение относитс к лесозаготовительным машинам и может быть использовано в лесной промышленности.The invention relates to logging machines and can be used in the forest industry.

Известна лессизаготовительна машина , содержаща т гач с гидроманипул тором и прицеп с шарнирно установленным на нем коником 1.The known lesszizgotovitelny machine, containing t gauge with a hydraulic manipulator and a trailer with a horseman hinged on it.

Эта машина характеризуетс недостаточной проходимостью и ограниченной маневренностью.This machine is characterized by insufficient maneuverability and limited maneuverability.

Цель изобретени - повышение проходимости и маневренности лесозаготовительной машины.The purpose of the invention is to increase the maneuverability and maneuverability of the logging machine.

Дл этого она снабжена закрепленными на.т гаче силовым цилиндром и двуплечим рычагом, одно плечо которого шарнирно соединено с силовым цилиндром а другое - с рамой прицепа , при этом шарниры соединени двуплечего рычага с силовым цилиндром, т гачом и прицепом разнесены в продольной вертикальной плоскости.To do this, it is equipped with a power cylinder fixed on the cylinder and a two-arm lever, one arm of which is pivotally connected to the power cylinder and the other to the trailer frame, while the hinges connecting the two-arm lever to the force cylinder are spaced in a longitudinal vertical position with the trailer.

Кроме того, между двуплечим рычагом и рамой прицепа размещен демпфер.In addition, a damper is placed between the two shoulder arms and the trailer frame.

На фиг. 1 изображена лесозаготовительна машина, вид сбоку, в работе , на фиг. 2 -.то же, в режиме холостого хода-, на фиг. 3 - машина, вид сзади .FIG. 1 shows a forest machine, side view, in operation, in FIG. 2-the same, in idle mode, in FIG. 3 - car, rear view.

Лесозаготовительна машина содержит гусеничное шасси 1, гидроманипул тор 2 с захватно-срезающим устройством 3, прицеп А. Рама последнего с помощью горизонтального шарнира 5 сое10 динена с двуплечим рычагом 6 и на ней установлен зажимной коник 7 с погрузочным рычагом 8. Рычаг 6 с помощью вертикально-горизонтального шарнира 9 размещен на раме 10 шасси. Одно The logging machine contains a tracked chassis 1, a hydraulic manipulator 2 with a gripping-cutting device 3, a trailer A. The frame of the latter with a horizontal hinge 5 so10 dinena with two shoulders lever 6 and a clamping conic 7 mounted on it with a loading lever 8. The lever 6 using vertically horizontal hinge 9 is located on the chassis frame 10. One thing

«5 плечо этого рычага соединено шарниром 11 со штоком силового цилиндра 12, установленного с помощью шарнира 13 Гука на раме 10. Между кронштейном И .прицепа Ц и вторым плечом "5 the shoulder of this lever is connected by a hinge 11 to the rod of the power cylinder 12, installed with the help of the hinge 13 Hooke on the frame 10. Between the bracket And. The trailer C and the second shoulder

Claims

20 of the lever 6 is installed damper 15, for example a spring. A support shield 16 is mounted on the rear part of the frame 10. Trailer i rests on a wheeled undercarriage 17; The axles of the hinges 5 9 and 11 are spaced apart at the corners of a triangle located in the longitudinal-vertical plane. The machine works as follows. To enter the forest in order to pack a pack, the trailer k is placed in the transport position. For this, the working fluid is fed into the headless cavity of the cylinder 12. The rod extends and turns the lever 6 around the hinge 9. Thanks to the hinge 5, the trailer 4 is folded and placed on the chassis 1 (Fig. 2), resting the wheels of the trolley 17 on the shield 16. . When the pack is assembled, the trailer k is unfolded into the working position (Fig. 1) Cylinder 12 is set to the floating position. The hydraulic manipulator 2 with the device 3 trees is cut down and the shaft cs onto the lever 8 (Fig. 3). which throws a felled tree into a conic 7. The packaged machine pulls into the loading dock. At the same time, the weight of the pack is distributed between the trailer cart 17 k and the self-propelled chassis 1. When driving through the cutting area, as well as loading trees into horses 7, the damper 15 reduces the dynamic loads on the frame 10. Setting this trailer to the transport position when idling significantly improves the maneuverability of the machine in the forest. This is especially true if a self-propelled chassis is used tracked vehicle with a small turning radius. It also reduces the length of the logging machine. Mounting the bunk 7 on the trailer and the lever 6 on the frame 10 is set in such a way that the weight of the pack falling on the bunk 7 is distributed between the chassis 1 and the bogie 17 of this trailer, providing the best throughput with optimum conic 7 lifting capacity. g connection of the lever 6 with the frame 10 is located at a distance of E (0.3--0.7) about from the center of mass, 7 at a distance of E (j (1.1 .. .1.5) 0 from the center of mass, and the axis of the carriage 17 of the trailer C is the distance of e (1.3 ... 2.0) Pp, where Cd is the distance from the center of mass to the axis of the landing gear sprocket 1. The economic effect is increased The average productivity of the machine is 300-500 rubles per machine compared to the known (PL-17) annual output. The industry's need for this type of machine is 1500 pcs. The annual economic effect of maximizing the use of the proposed machine is 50-750. thousand rubles. Formula of the Invention 1. A logging machine containing a gach with a hydraulic manipulator and a trailer with a horseman hinged on it, which is equipped with, for the purpose of increasing its maneuverability and maneuverability. fixed at m Slack power cylinder and a double-armed lever one arm of which is pivotally connected to the power cylinder and the other by the trailer frame, the hinges of the compound two-armed lever with the power cylinder, towing vehicle and trailer are spaced in a longitudinal vertical plane.

2. Our unit according to claim 1, characterized in that a damper is placed between the two-arm and the frame of the trailer. Sources of information taken into account during the examination 1. USSR author's certificate V 5891 “5. cl. In 60 P J / tO, 1975 (prototype).
