Abstract

The invention relates to forest machine engineering and can be used in point tree planting machines. The aim of the invention is to increase the efficiency of tree planting. The device comprises an arrow 3 connected to the tractor 4. A ferrule 1 is attached to the second end of the boom, in which the hollow body 2 with hole-forming flaps 9 at the end is linearly movable. Seals 12 and hydraulic cylinders 11 are installed on the cage, as well as seals on the cranks or in the guides and are movable relative to the cage. The cylinders are associated with a hollow body and with seals. With continuous movement of the unit when the boom is lowered, the sealing wedges 15 and the sash 9 of the hollow body are buried in the soil, then the sash is opened, the seedling is placed in the hole, the sash is deepened and soil is compacted around the well by turning on hydraulic cylinders 11. the moment the valves leave the soil, the hydraulic cylinders are included in the general network in parallel, and adjustable relief valves and check valves are connected to one of the cavities of the hydraulic cylinders of the seals. The closing wedges 15 move the soil to the well during the period of the digging of the valves and improve the conditions of subsequent compaction. 5 il.

cranks or in guides and can be moved relative to the yoke. The cylinders are associated with a hollow body and with seals. With the continuous movement of the unit, when lowering the boom, the wedges 15 and the valves 9 of the hollow body are embedded in the soil, then the valves open, seedling is placed in a lup, the valves deepen and the soil is compacted around the lupa by turning on hydraulic cylinders 11. in the seal until the leaves come out of the soil, the hydraulic cylinders are connected to the common network in parallel, with adjustable bypass and check valves connected to one of the cavities of the hydraulic cylinders of the seals. The closing wedges 15 move the yuchva to the hole during the period of deepening of the valves and improve the conditions of subsequent compaction. 5 il.

The invention relates to forestry machines and can be used in point tree planting machines.

The purpose of the invention is to increase the efficiency of tree planting.

FIG. Figure 1 shows the landing gear with seals placed in ycTanoBjicHiibix on the rails of the rails, side view; FIG. 2 is the same, front view; in fig. 3 landing device with gaskets., KOTOpi), i.e. located on the cranks mounted on the holder at the moment of the beginning and end of the compaction, side view; in fig. 4 is the same, front view; in fig. 5 hydrocycline incorporation circuit; 1p.

The landing gear (Figs. 1 and 3) consists of a clip 1, of which a hollow body 2 is placed. Ob1 1 is hingedly connected to the boom 3 of a tractor or a logging machine 4 operated by a hydro-cylinder 5. Spring-loaded relative to the boom by a spring 6 and the arrow has an emphasis 7, which interacts with the wallpaper. my 1 at the initial one. the landing gear (Fig. 1, dash-dotted contour). The hollow body 2 moves in the vessel under the action of a hydro-cylinder 8 fixed on the vessel and connected with the hollow body 2. In the lower part of the hollow body there are pivotally mounted hole-like structures of the hydraulic cylinder 9 installed on the floor. ten.

The hydraulic actuators 11 of the compactors 12 are also mounted on the holder 1. The latter, in the first embodiment, are mounted on the holder 1: Guides 13, or secondly on the cranks 14. The wedges 15 are also placed with a restriction 16 depth .

The cylinders of the landing gear can be controlled by the operator or by using a control system (not shown). To simplify the management of the psni and to perform a predetermined sequence of operation, the hydraulic cylinders 8 and 11 can be included in the general hydraulic network in parallel. To regulate the moment of commencement of compaction and to ensure guaranteed compaction after digging the hole-forming cusps 9, adjustable bypass 17 and check valve 18 are connected to one of the cavities of the first cylinder 11. Landing device works as follows.

During the movement of the unit, the seedlings from the store (not shown) enter the hollow body 2 and move down to the stop into the shutter 9, which is in the closed state. The stem 1 of the cylinder 8 is pulled out, and the long body occupies the upper position. Iloc. i.e. the activation of the hydraulic cylinder 5, the arrow 3 is lowered down together with the yoke 1 and the hollow body 2 until the wedges 15 are buried until the limiter 16 stops against the ground. Pos iei o lowering the boom ceased 5 steps. Due to the action of the spring 6 and the stop 7, the hollow body has an inclined position (ph .. 1, dash-dotted lines).

The hydraulic cylinder 8 is then turned on, and the hollow body starts to be buried. With the continued movement of the unit, the hollow body is deepened with a simultaneous rotation together with the yoke relative to the boom 3. After the hydraulic cylinder 8 of its descent has been completed, the valves 9 are recessed into the ground,

5 and the hydraulic cylinder 8 automatically switches off automatically.

After the landing gear is rotated at a predetermined angle, the hydraulic cylinder I), the extension of the rod of which deploys the chunking-forming flaps 9, turns on

In this, the plant moves downwards under the action of the force of gravity and enters the hole thus formed.

When the hydraulic cylinder 8 is turned on in reverse, the hollow body together with the flaps 9 deepens, leaving the plant in the hole, with this landing device bypassing the vertical position and continuing to rotate due to continuing

the movement of the aggregate and the locking action of the wedges.

By turning on the hydraulic cylinders 1 1, the seals 12 are moved downwards relative to the holder 1 and the roots are squeezed by the soil.

After the seal is complete, the hydraulic cylinders 5 are turned on and, with a time delay, the hydraulic cylinders 10, the boom 3 is raised, the flaps 9 are shifted, the landing gear is in its original position, and the cycle is repeated.

When the hydraulic cylinders 8 and 11 are connected in parallel and the oil is supplied to their piston cavities by adjusting the valve 17, the hollow body 2 will be raised first with the flaps 9. After the flaps come out of the well with the hydraulic cylinders 8 fully extended, the pressure in the network increases, the valve 17 opens, and under the action of the hydraulic cylinders 11, the seals 12 are pressed into the soil.
