Description

The invention relates to logging equipment, in particular to a machine pulling device for pruning knots C of fallen trees.

Known drags maDJHiu device for trimming streams comprising lodvizhno mounted on the guide carriage, 3i: XBaT e Wade closed-nleniyh on the carriage and a toothed comb mobility hydrochloric clamping jaws with corrugated contact loverhaostyu and reversing the carriage with the rope trrivod bypass blocks.

The disadvantages of the known devices of this kind are the complexity of the design and their low H; pO, 1 CRUISE due to the need to move the carriage over the entire length of the prot. Frame: a portable device and the duration of the capture cycle and release-stem.

In iredlagaemom device nodvizhna gripping jaw is formed with a vertical rib, which is fixed toothed sector hraayuvoto mechanism formed zatsenleniem this sector biased yu locking pawl provided with unravl yuidim roller envelope blank branch reversing rope drive, the end of which is connected to the pivot nodvizhnoy jaw , and the bypass unit of the idler of the rope drive is equipped with a controllable power drive that alternates it along the device's irodol axis.

FIG. 1 is a schematic representation of the device, side view; on phpg. 2 - carriage with zakhzato; in fig. 3 is a view along arrow A of FIG. 2

The pull-in device consists of a carriage 1 with a crutch 2, a P01 welded jaw 3 gripper, a horizontal axis 4 and a set is installed in the carrier 5. On the carriage / there is a tooth comb 6, which serves to better grip the gripper with the trunk of the tree. The pivot jaw 3 of the grip has a saddle-shaped bearing surface with pointed ribs 7 for secure adhesion to the surface of the Stol. On the side of the jaw: the grip has a vertical stiffener 8, on which is attached a spider 9 of the storage mechanism. With a notched sector 9 in a zatse-fillet} 1e of the assembly, a locking pawl / s} of the steering roller 11. An axis 12 of the pawl 10 and its spring dem. 13 are located 13 on the side of the bracket 2. The carriage / set iodvig .o on the naive 14 and connected to the rope 15, with an axle in motion of the reversing winch 16. The working branch of the rope / 5 1-frame, ggs to the base of the carriage /. The branch of the rope is free-running. through the guiding device 17 under the ocHOBJiriJie kapet /, then it goes around the horizontal block 18 and the block 19, reinforced to the side under the bracket 2, touches the control roller 11 on the tapped doggie 10, then, rounds the block 20, fixed by the axis 4 of jaw 3 and fastens on it. A trailing cable 15 is used for the control of the turnaround jaw 3 and the ratchet mechanism. For this branch of the rope, by means of ineipe displacement, nashrpmer, obvatvvogo block 2 / m-ogt be (nattu or relieved with the help of a pack of power The work of the pushing device is carried out in the following ways: The next barrel 24 with a twig is laid in the cutter head 23 from the rifle machine. The idle branch of the traction rope 15 is the carriage / fed 1pl butt of the trunk. 5, which automatically turns on the power supply voltage: the junction 22, "closed upper section of the caiata 15, in addition to movement, internal tension is reported. The idle branch is tensioned, pressed through the controlling roles; 11 dogs / 10.1 remove its gearing with the toothed sector 9 and through the block 20 rotates the jaw 3 of the gripper to the upper position. The butt of the barrel will be placed between the jaw 3 and the base of the carriage 1, the latter is stopped by disabling the drive of the winch 16 1 and turn off the drive 22 for tensioning the rope. Single branch of the rope 15. Receives slack. Jaw 3 under its own weight freely lowers onto the trunk and in this position through the toothed sector 9 of the storing mechanism is fixed by a podruzhennoy pawl 10. The roller // under the action (spring damper 13 easily pushes the relaxed rope of the idle branch to the side. Tangled rope is conveyed in the working direction The tree trunk is firmly wedged between the sharp ribs 7 of the jaw 3 and the toothed comb in. In this position, the tree with the limbs is pulled through the power cutting knives 23. When the trunk is in the working position, the path is equal to its length or the length of the sawn assortment, the winch is turned off, the rammer 22 is turned on by an actuator 22, which, by pulling, acts through roller 11 on sabac 10. 10. The latter is twisted relative to Axis 12, and its tooth goes out out of engagement with the ratchet gear sector 9. When the rope is further tensioned, the jaw 3 rises, releasing the trunk, the whip or the extended log is dropped to the side, and the carriage is / is idled for entering and pulling the next trunk. The loading of especially zakomelistyh trunks in the seizure is performed in a different sequence. First, the carriage / is fed into the loading zone, and then into the open side grip of the plant a tree trunk. When the tree trunk is placed in the jaw area 3 of the gripper, the ayl drive 22 of the tension of the Kanat 15 is turned off, and further, the operation cycle of the device is carried out in the above order. In medium-size and shorter-stroke shafts, the gripping carriage 1 works, performing a continuous reciprocating motion, and thereby, the penetration rate of the device in the limbing machine increases significantly. The reciprocating path in reciprocating motion can be taken along the length of the whip or pushed type graft when the branch pruning machine is used in conjunction with a cutting machine. In this case, the capture of the carriage when dragging the trunk works with “inepe .X into an atom. P IP e | D m ate and b ate e. And a pulling device of the pruning machine, including movably mounted on the guide carriage, the grip in the form of a fixed comb and a movable 1 jaw with a a grooved contact surface and a reversible cable carriage with a carriage with bypass blocks. and characterized in that, in order to simplify the design and increase productivity, the jaw grip is made with a vertical stiffening rib; a ratchet mechanism is fixed on the KOTopoiM a, formed by the engagement of this sector with a spring-loaded locking pawl, which was equipped with a control roller, enveloping the idle branch of the reversible cable (privada, the end of which is connected to the axis of rotation of the moving jaw, and the bypass unit of the idler branch of the cable drive is equipped with a controlled force jaw. it along the longitudinal axis of the device.
