Implementation

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

As shown in Figure 1, a logging machine includes a holding group 1, a collection group 2, a saw blade group 3, a load-bearing column 4 and a hydraulic station (5);

As shown in Figure 2, the holding group 1 includes a lower box body 11 fixed below the load-bearing column 4, a holding group sleeve 12 fixed on the load-bearing column 4, and a left holding group hinged on both sides of the holding group sleeve 12. Tight claw 13 and right grip claw 14 and the first kinematic mechanism 15 and the second kinematic mechanism 16 that are connected on the left grip claw 13 and the right grip claw 14; Tight claw 13 and right grip claw 14 are staggered up and down. A first hydraulic cylinder 17 is hinged on the left holding claw 13 and the right holding claw 14 .

The first movement mechanism 15 and the second movement mechanism 16 are respectively provided with a second hydraulic cylinder 18 and a third hydraulic cylinder 19 . Two ends of the second hydraulic cylinder 18 are respectively hinged with the left holding claw 13 and the first motion mechanism 15; two ends of the third hydraulic cylinder 19 are respectively hinged with the right holding claw 14 and the second motion mechanism 16. Claws are used to hold trees tightly to ensure the stability of the machine work. The first hydraulic cylinder 17 is adopted to make the claws hold trees tightly, which is strong and reliable.

Gears are installed on the first kinematic mechanism 15 and the second kinematic mechanism 16 and are driven by motors. The first and second kinematic mechanisms are used for the movement of logging machines. The drive gear turns, allowing the logging machine to move up and down the trunk of the tree.

As shown in Figure 3, the collection group 2 includes a turntable bearing 26 fixed on the load-bearing column 4, a collection group sleeve 22 connected with the turntable bearing 26, an upper box body 21 fixed on the collection group sleeve 22 and hinged to the collection group. The left collecting claw 24 and the right collecting claw 25 on both sides of the sleeve 22; the left collecting claw 24 and the right collecting claw 25 are hinged with a fourth hydraulic cylinder 27. The left collecting claw 24 and the right collecting claw 25 hinged on both sides of the collecting group sleeve 22 are staggered up and down. The collection claw is used to catch the felled trees, and the collection group 2 can rotate around the load-bearing column 4 through the rotation of the turntable bearing 26, thereby controlling the direction of falling of the trees, and avoiding the risk that the trees may fall and hit people.

Upper casing 21 tops are equipped with upper cutting piece 23, and left gathering claw 24, right gathering claw 25 tops are edged, can repair and remove tree outer branch fast when felling machine moves upwards along the trunk of trees.

The turntable bearing 26 is driven by a motor, and the turntable bearing 26 is a worm wheel turntable bearing, which can be self-locking, and can prevent the collection group from overweight and uncontrolled rotation after catching the felled trees.

The saw blade group 3 is installed above the lower box body 11 of the tight group 1, including a casing and an electric saw, and the electric saw can swing for cutting trees.

The first, second, third and fourth hydraulic cylinders in the machine are powered by the hydraulic station 5 located outside the lower box body 11 .

The machine is powered by an external wire.

Working process of the present invention is as follows:

Place the felling machine at the bottom of the tree, hold the tree lightly with the holding claws and collecting claws, the gears in the first and second movement mechanisms hold the tree tightly, and the motor drives the gear to rotate, so that the felling machine moves upward along the trunk of the tree , upper cutting piece 23, left collection paw 24, right collection pawl 25 will prune the outer branches of trees in the moving process. After trimming the outer branches, the logging machine moves to a suitable position, the holding claws and collecting claws tightly hug the tree, the chainsaw swings, and cuts the tree, so that the tree is separated from the part hugged by the collection group 2 and hugged by the hugging group 1 The part is separated, and then the turntable bearing 26 drives the collection group 2 to rotate, so that the cut part of the tree is transferred to the rear of the machine, and then the first and second movement mechanisms drive the machine down to transport the part of the tree to the ground. When a felling is completed. The machine then moves up the trunk of the tree, felling the tree again, and repeats the process until one tree is felled.

In the present invention, the upper cutting piece and the left and right collecting claws quickly remove the outer branches of the tree during the upward movement of the logging machine along the trunk of the tree, which reduces the need to process the outer branches of the tree after the original felling of the tree, and improves the efficiency. . The present invention cuts down trees by cutting and transporting them section by section, avoiding the uncertain direction of trees toppling and the hidden dangers of production safety that are easy to hit people, and ensuring the safety of the logging process.

The above detailed description is a specific description of the feasible implementation of the present invention. This implementation case is not used to limit the patent scope of the present invention. All equivalent implementations or changes that do not deviate from the present invention should be included in the patent scope of this case. .
