Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of tree felling, and particularly relates to a tree directional felling device. BACKGROUND

[0002] At present, when trees are felled in the wild, a special oil saw is usually used by manual operation to cut down and saw off the trees. In the sawing-off process, the hand-held part of the oil saw needs to be held by manpower to control the stable operation of the oil saw and keep the sawing surface of the tree trunk as flat as possible, which is a large amount of labor. In addition, in order to prevent the tree from injuring the felling personnel when it falls down, an auxiliary tool is usually arranged to make the tree fall in a specified direction. For example, a patent with application number CN202010322951.6 discloses a directional tree felling device, which comprises a vehicle body, third mounting plates are arranged on the lower surfaces of the left and right sides of the vehicle body, a rotating rod is rotatably connected to the lower part of the third mounting plate, wheels are arranged on the front and rear ends of the rotating rod, a fixed plate is arranged on the upper surface of the right side of the vehicle body, a second cylinder is arranged on the middle part of the upper surface of the vehicle body, the piston rod of the second cylinder is fixedly connected to the left middle part of a push plate, the right side of the push plate is connected to first sliding rods at the front and rear ends, the right end of the first sliding rod is connected to a first mounting plate, a first rotating shaft is arranged in the middle part of the first mounting plate, a cutting wheel is arranged on the lower part of the first rotating shaft, a connecting rod is arranged on the middle part of the push plate, and the upper end of the connecting rod is connected to the left end of a second sliding rod. The tree is fixed by arranging a clamping plate, so that the tree is in a fixed state during the whole tree felling process, and the top plate arranged on the upper part keeps being tightly pressed, so that the falling direction of the tree can only be to the right side, thereby ensuring the safety of the whole tree felling process. However, the technical scheme can only cut the roots of the tree when in use, and if the tree is high, the radius during falling will be large, which is easy to hit or be stuck in other tree trunks around, thereby causing damage to some protected trees (such as famous trees and old trees) or trees that do not need to be felled.

[0003] In view of the above-mentioned defects in the prior art, the present application is produced through in-depth research. SUMMARY

[0004] The purpose of the present application is to provide a tree directional felling device, which cuts the tree trunk in sections from top to bottom, prevents the sawed-off tree trunk from hitting or being stuck in other tree trunks around, and avoids causing damage to other trees.

[0005] To achieve the above technical purposes, the technical scheme adopted by the present application is as follows:

[0006] The tree directional felling device comprises a tree climber, the tree climber comprising an upper climbing wheel, a lower climbing wheel and a mounting frame, the lower climbing wheel being driven by an engine, the upper climbing wheel and the lower climbing wheel being respectively located on two sides of a tree trunk, and the lower climbing wheel being located below the upper climbing wheel, further comprising a chainsaw, a directional felling mechanism and a seat installed on the tree climber; the mounting frame comprises an upper support, a lower support and a connecting frame, the upper climbing wheel and the lower climbing wheel being installed on the connecting frame; the directional felling mechanism is movably installed on the upper support, the chainsaw being located below the directional felling mechanism, and the seat being installed on the lower support; the directional felling mechanism comprises a turnover plate connected to the upper support, two arc-shaped plates pivotally connected to two sides of the turnover plate, and a locking member for fixing the two arc-shaped plates; a connecting plate is formed on a side wall of each of the two arc-shaped plates and connected to the turnover plate, a turnover block is formed on a bottom of the turnover plate and hinged to the upper support, and the turnover plate can be reciprocally turned up and down in a vertical direction about the upper support; an upper end of a side of each of the two arc-shaped plates away from the turnover plate is provided with a locking hole, and the locking member comprises a connecting piece and two locking rods located at a bottom of the connecting piece and capable of being inserted into the locking hole.

[0007] Further, a baffle is arranged at a bottom of the upper support, a buffer plate is arranged at a top of the baffle, a top of the buffer plate is hinged to a top of the baffle, a damping spring is further arranged between the buffer plate and the baffle, and two ends of the damping spring are respectively fixedly connected between the buffer plate and the baffle. When the upper section of the felled tree trunk falls, it will hit the tree climber on the lower tree trunk. The buffer plate and the damping spring can reduce the shaking strength of the lower tree trunk and protect the felling personnel, thus being safer.

[0008] Further, a traction rope is arranged to force the directional felling mechanism to turn down; a bearing column is arranged at a bottom of the lower support, a support plate is slidably installed on the bearing column, and two foot pedals are arranged on the support plate; a connecting rod is arranged at a top of the turnover plate, one end of the traction rope is fixedly connected to the connecting rod, and the other end of the traction rope is fixedly connected to the support plate; a first supporting rod is horizontally arranged on the upper support, a first pulley is arranged at a front end of the first supporting rod, a second supporting rod and a third supporting rod are vertically arranged at the bottom of the lower support; a second pulley is arranged at an end of the second supporting rod, and a third pulley is arranged at an end of the third supporting rod; the length of the third supporting rod is less than the length of the second supporting rod, and the traction rope is arranged on the first pulley, the second pulley and the third pulley. After the tree trunk is sawn, the felled tree trunk can be quickly felled by pressing the foot pedals downward and through the traction rope.

[0009] Further, the bearing column is formed with a sliding channel for the support plate to slide up and down, the support plate is formed with a sliding block matched with the sliding channel; the sliding channel is further provided with a reset spring; the bottom end of the reset spring is fixedly connected to the inner bottom wall of the sliding channel, and the top end is fixedly connected to the bottom of the sliding block. The reset spring can quickly reset the support plate.

[0010] Further, the upper support includes a first support and a second support fixedly connected to the connecting frame, the first support is perpendicular to the second support in the horizontal direction, the first support is located on the side close to the connecting frame, and the directional tilting mechanism is installed on the second support; the upper support further includes a third support and a fourth support; one end of the third support is rotationally connected to the end of the second support, one end of the fourth support is rotationally connected to the third support, and the other end is clamped to the first support; the first support and the fourth support are connected through a latch. The third support and the fourth support are movably connected, which facilitates clamping the upper climbing wheel and the lower climbing wheel to the tree trunk when the tree climber is installed.

[0011] Further, the chainsaw is slidably installed on the top of the third support, the top of the third support is formed with a sliding groove, a sliding block is slidably arranged in the sliding groove, a connecting hole is formed in the sliding block, and the saw handle of the chainsaw is rotationally connected in the connecting hole. The sliding groove is formed in the third support, the chainsaw is slidably installed in the sliding groove, and the chainsaw is controlled, thereby saving labor.

[0012] Further, the top of the fourth support is provided with a protective plate. The protective plate can prevent the chainsaw from accidentally injuring the felling personnel.

[0013] Compared with the prior art, the directional felling device for trees of the present application has the directional tilting mechanism and the chainsaw installed on the tree climber. When felling, the felling personnel can sit on the tree climber, climb above the tree trunk, and make the two arc-shaped plates close to surround the tree trunk. At this time, the tree trunk is cut off by the chainsaw, and under the action of tilting, the cut-off tree trunk can only fall in the direction of the tilting plate. After the tilting exceeds 90°, the tree trunk can start to slide down until it falls off from the arc-shaped plate. At this time, since the cut-off tree trunk is short, the radius of the tilting fall is also small, so it is not easy to hit other trees, thereby avoiding damage to other trees.
