Description

Technical Field

[0001] The utility model relates to the technical field of tree felling direction control, in particular to a falling direction control device used for forest tending and tree felling. Background Art

[0002] Forest tending, also known as stand tending, refers to the various measures taken in the forest cultivation process from afforestation to maturity to ensure the survival of young forests, promote tree growth, and improve forest productivity. There are many forest tending measures, which can be divided into two categories: tree tending and woodland tending, including artificial pruning, tending and felling operations. Through forest tending, the growth potential of trees, the quality of stands and the ability to resist natural disasters, and the productivity of woodland can be improved.

[0003] At present, forest tending and tree felling operations are mainly completed manually. When felling trees, it is necessary to control the direction of the felled trees to avoid damaging other trees. The conventional method of controlling the direction of the trees is that the fellers cut a wedge on the side where the tree is falling, and then observe the nearby point where the tree is falling. Multiple workers roughly control the direction of the tree by pushing. This direction control method improves the felling efficiency, but the labor intensity of the fellers is high. There is also a method of dragging by tying ropes. This method requires the fellers to climb the trees. There are safety hazards in the climbing process, and the tying methods vary from person to person. If the tying is not firm, the rope buckle will loosen when dragging the tree, or the tree falls and drags the workers and equipment, causing equipment damage and personal safety problems.

[0004] Therefore, the present application provides a falling control device for forest tree tending and felling to solve the problems raised in the above-mentioned background technology. Utility Model Content

[0015] A further improvement of the technical solution of the utility model is that anti-skid grooves are respectively arranged on the surfaces of the upper embedded plate and the lower embedded plate, and the anti-skid grooves are close to the front corner tips.

[0016] By adopting the above technical solution, the utility model has the following beneficial effects:

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] The present invention will be further explained below in conjunction with specific implementation methods.

[0034] like Figure 1-6As shown, the present embodiment provides a falling control device for forest tending and felling trees, comprising an upper embedded plate 1, wherein the upper embedded plate 1 and the lower embedded plate 6 together form an inner angle 10, wherein a connecting belt 5, a spring 7 and a jacking mechanism 9 are respectively installed in the cavity of the inner angle 10, wherein the jacking mechanism 9 is connected to a fixed sleeve mechanism 2, wherein the fixed sleeve mechanism 2 is adapted to a rotating shaft mechanism 3, wherein the rotating shaft mechanism 3 is adapted to be nested in the inner cavity of the fixed sleeve mechanism 2 for rotational displacement; wherein the rotating shaft mechanism 3 is rotated to push a jacking plate 91 in the jacking mechanism 9 to rise and fall; and wherein the jacking mechanism Structure 9 also includes a lifting seat 92, which is a trapezoidal body and has an inner cavity 94. A lower fixed block 93 is fixed to the bottom surface of the inner cavity 94, and a lower arc groove 97 is arranged on the upper surface of the lower fixed block 93. The inner diameter of the inner cavity of the lifting seat 92 is adapted to the outer diameter of the lifting plate 91. An upper fixed block 95 is fixed to the bottom surface of the lifting plate 91, and an upper arc groove 96 is arranged on the bottom surface of the upper fixed block 95. A rotating shaft 31 is adapted between the lower arc groove 97 and the upper arc groove 96, and the rotating shaft 31 is adapted to abut against the upper arc groove 96, so that the upper arc groove 96 can be raised and lowered. The upper embedded plate 1 and one end of the lower embedded plate 6 are connected to form an inner angle 10, and a lifting mechanism 9 is installed in the inner angle 10. The lifting mechanism 9 is composed of a lifting seat 92 and a lifting plate 91.

The outer diameter of the lifting plate 91 is adapted to the inner diameter of the lifting seat 92. The lifting seat 92 is a hollow cavity, and a lower fixing block 93 is installed on the bottom surface of its inner cavity 94. The lower fixing block 93 is vertically and symmetrically installed with an upper fixing block 95 fixed to the bottom surface of the lifting plate 91 body. Due to the design of the upper fixing block 95, the lifting plate 91 cannot be separated from the inner cavity 94. The height of the upper fixing block 95 is greater than the lower fixing block 93, which prevents the lifting plate 91 from being separated from the inner cavity Cavity 94, a lower arc groove 97 is set on the top surface of the lower fixed block 93, and an upper arc groove 96 is set on the bottom surface of the upper fixed block. The lower arc groove 97 and the upper arc groove 96 are vertically and symmetrically arranged. The arc shape of the upper arc groove 96 body is smaller than the arc shape of the lower arc groove 97. The lifting height of the rotating shaft 31 is increased by reducing the area of ​​the upper arc groove 96. The lower arc groove 97 and the upper arc groove 96 are in contact with the conical head 32 in the rotating shaft 31. The height of the lifting plate 91 is controlled by the thickness of the conical head 32; the lifting plate is moved up by rotating the rotating shaft, driving the expansion and contraction of the upper embedded plate and the lower embedded plate to realize the control of the falling direction of the trees; the tree fellers only need to rotate the rotating shaft to realize the separation and falling control of the trees, which greatly reduces the labor intensity.

[0035] like Figure 2-3 , Figure 5-6As shown, in this embodiment, the lifting seat 92 is a trapezoidal body, and a fixing sleeve mechanism 2 is installed through the bottom surface of the trapezoidal body. The fixing sleeve mechanism 2 also includes a fixing sleeve 21, and a fixing ring 22 is fixedly arranged at the bottom end of the fixing sleeve 21, and the fixing ring 22 abuts against the inner wall of the inner cavity of the lifting seat 92; the inner cavity of the fixing sleeve 21 body is through, and an internal thread 23 is arranged on its inner wall; the internal thread 23 is adapted to the thread 33 in the rotating shaft mechanism 3, and the rotating shaft mechanism 3 also includes a rotating shaft 31, and the upper and lower parts of the rotating shaft 31 body are respectively provided with threads 33 and a conical head 32, and a rotating handle 4 is arranged at the top of the rotating shaft 31; the lifting seat 92 is a trapezoidal body, and a fixing sleeve mechanism 2 is installed through a side wall of the trapezoidal body close to the rotating handle 4, and the fixing sleeve mechanism 2 also includes a fixing sleeve 21, and the bottom end of the fixing sleeve 21 A fixing ring 22 is fixedly arranged, and the fixing ring 22 is fixed against the wall of the inner cavity 94. The inner cavities of the fixing sleeve 21 and the fixing ring 22 are connected, and an internal thread 23 is arranged on the inner wall thereof. The internal thread 23 is adapted to the thread 33 in the rotating shaft mechanism 3. The thread 33 is an external thread, and the thread 33 and the internal thread 23 are adapted to rotate and move. The thread 33 is arranged on the main body of the rotating shaft 31. The upper part of the main body of the rotating shaft 31 is the thread 33, and the lower part of the main body is a conical head 32. A rotating handle 4 is arranged on the top of the rotating shaft 31; the total length of the rotating shaft mechanism 3 is greater than that of the fixing sleeve mechanism 2. The jacking mechanism in the device is simple in structure, compact, easy to carry, more durable, and not easy to be damaged. The expansion and contraction of the upper and lower embedded plates are realized only by the adaptation and rotation of the threads, thereby realizing the inversion control of the trees.

[0036] like Figure 1-2 As shown, in this embodiment, the upper embedded plate 1 and the lower embedded plate 6 together form an inner angle 10, and springs 7 are symmetrically arranged at the edges of both sides of the inner angle 10 near the corner tip 11; the edges of both sides of the inner angle 10 are symmetrically arranged at the edges near the fixing sleeve mechanism 2, and the connecting belts 5 are flexible shrink belts; the surfaces of the upper embedded plate 1 and the lower embedded plate 6 are respectively provided with anti-skid grooves 8, and the anti-skid grooves 8 are close to the front corner tip 11; the upper embedded plate 1 and the lower embedded plate 6 together form an inner angle 10, and the size of the inner angle can be adjusted according to the needs of the tree fellers, and within the inner angle 10 Springs 7 are symmetrically arranged near the corner tips 11 on both side edges, and both ends of the springs 7 are connected to the upper embedded plate 1 and the lower embedded plate 6, so as to facilitate the expansion and contraction of the upper embedded plate 1 and the lower embedded plate 6. Similarly, connecting belts 5 are symmetrically arranged near the fixing sleeve mechanism 2, and the connecting belts 5 further control the expansion and contraction of the upper embedded plate 1 and the lower embedded plate. Through the corner tips at the common connection of the upper embedded plate and the lower embedded plate, and the anti-slip grooves on the surfaces of the upper embedded plate and the lower embedded plate, the device can be more easily embedded in the gaps sawn by trees. The device is simple to operate and convenient to use.

[0037] The utility model also provides a working principle of a falling control device for forest tending and felling trees: the tree feller first saws the tree, and when the tree is sawed to the half or the critical point of falling, the tree feller embeds the device into the sawn gap, and the number of devices to be used can be determined according to the needs of the tree feller or the falling direction, and the corner tip connected with the upper embedding plate and the lower embedding plate is embedded in the sawn tree, and the outer sides of the surfaces of the upper embedding plate and the lower embedding plate are provided with anti-skid grooves, and the protective grooves are used for slipping. By rotating the rotating shaft rod in the device, the rotating shaft rod is adapted to be assembled in the fixed sleeve, and the fixed sleeve is provided with an internal thread, and the internal thread is adapted to the thread set on the upper part of the rotating shaft rod. When the tree feller rotates the rotating shaft rod, the conical head at the lower part of the rotating shaft rod body abuts against the lower fixed block and the upper fixed block respectively adapted in the jacking seat and the jacking plate, and a lower arc groove is provided on the top of the lower fixed block, and an upper arc groove is provided on the bottom of the upper fixed block. The arc groove and the upper arc groove abut against the conical head together, and the conical head slides in the lower arc groove and the upper arc groove. When the tree feller rotates the rotating shaft rod clockwise, the rotating shaft rod is in a state of lifting the lifting plate forward. Due to the coarse and fine structure of the conical head itself, when the rotating shaft rod lifts the lifting plate forward, the conical head moves forward from thin to coarse, thereby making the lifting plate abut against and push the upper embedded plate to move upward, thereby realizing the expansion of the trees, thereby realizing the falling control of the trees, and improving the falling accuracy. According to the diameter of the trees, multiple devices can be used for falling control. When the trees fall, the tree feller rotates the rotating shaft rod counterclockwise to return the rotating shaft rod to the thin end of the conical head, which is convenient for the next use. The device has a simple and compact structure, is easy to carry, has stronger durability, is not easy to damage, and only realizes the expansion and contraction of the upper and lower embedded plates through threaded adaptation and rotation, thereby realizing the falling control of the trees and reducing the labor intensity of the tree fellers.

Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
