Description

one

The invention relates to machines used in logging work.

The known conic of the machine for skid-free cutting of trees, including the receiving beam in the form of two plates parallel to each other, forms, between them is called for insertion of the jaws of the grip.

However, the well-known conic machines do not provide reliable fastening of a pack of trees on it.

In order to ensure reliable fastening, the packs of trees in the proposed conic of the receiving beam plate are unevenly high, one of which has triangular protrusions with pointed side edges.

FIG. Figure 1 shows the proposed machine for chainless skidding of trees: position I is the moment of the collection of trees from the ground; position II - transport; pas figs. 2 is a diagram of filling the jaws with trees on the ground (type A); in fig. 3 is a diagram of securing a pack of trees between the jaw and the conic ridge (type B); in fig. 4 shows a section along BB in FIG. 3; in fig. 5 is a scheme for fixing a single tree on a conic.

The frame of the self-propelled chassis 1 is fixed to the nesunha platform 2, on which the canopy of the first equipment is mounted, including the L-shaped boom 3 with the handle 4, the jaw

a grip 5 driven by a hydraulic cylinder 6, a conic 7, two hydraulic drives 8 boom actuators, a hydraulic cylinder 9 for driving a boom arm, an articulated arm suspension 10 consisting of a cross 11, in which an axis 12 passes, on top of which a figured disc is fixed 13. In the middle part of the platform on the pivot 14, a conic beam mounted on the pivot 14 is mounted on the crossbar and right, including a bearing disc 15 and two plates parallel in the vertical plane — the front plate 16 and the rear plate 17, between which is formed: h. The back plate is above the front and has triangular projections; its upper edge is sharpened at an angle of 50-55 ° at the top. The disk on the pivot is fixed and self-installing by springs 18. Beam 19 is installed above the rear axle to protect crankcase cranks from accidental damage.

Konik machine for beschernon trelepki trees works as follows.

The machine approaches the pack and, if necessary, if the butt ends of the part of the pack are not aligned, or if it is necessary to “tear the pack off, as it happens in winter, these works are carried out using a bulldozer crash. The machine is turned around and retracted to the pack. By lowering

the booms 3 and the arms 4, the maxillary gripper 5, are pushed onto the pack, the jaws are wrung out the pack, raised by boom 3 to a height of 1.4 m from the ground, i.e. equal to the height of the upper edge of the conic, then simultaneously with the subsequent iodoom t under the filling until the moment when the jaws of the gripper 5 are above the groove of the conic 7, then the machine is stopped.

In the process of loading, the pack remains stationary in the longitudinal direction (Fig. 2), the machine moves the node of the lifted pack, therefore, the slipping of the pre-compressed logs from the jaws is excluded.

After that, the handle 4 slides down onto the conic ridge (Fig. 3), the jaws are inserted into the open groove between the plates 16-17.

The hydraulic cylinder 6 of the grip 5 compresses the pack of whips of force L from the sides, and the arrow of force P presses the pack against the conic. The upper edge of the plate 17, being sharp, punched; in a tree trunk.

The loading and fastening of single-tree trees is also carried out, so the capture of 5 "ca; it is attached to it with closed jaws.

Thus, the butt part of the pack is placed on the horse conic machine. Rotation of the car when moving with a cart is provided at an angle close to 85, B both sides. Keeping the packs of whips from side-to-side mixing on the tops of the hoods ensure that the comb is a conic; made in the form of two projections of a triangular shape. The retention of packs from the longitudinal change is ensured by sharpening the edge of the ridge of the conic at an angle of 55 ° but the entire working length.

When unloading py1: about 4, raises the pack up so that the jaws of the grip are higher than the projections of the figured conic plate 17. Then, when the cylinder of the boom 8 is floating, the machine comes out from under the pack; at the moment when the butt end of the ends is behind the rear axle of the machine, the jaws

capture open pack unload.

Subject Invention

Konik machine for skid-free skidding of trees, including the receiving beam in the form of two plates parallel to each other, forming between each other a groove for inserting the jaws of the grip, characterized in that cher:,; one of them has triangular protrusions with pointed side edges.
