Description

Technical Field

[0001] The invention relates to the technical field of tree cutting, and in particular to a tree cutting device. Background Art

[0002] In the power industry, the safe operation of transmission lines is of vital importance, and the growth of trees along transmission lines often becomes an important factor affecting the safety of power facilities. With the improvement of the ecological environment, the number of trees around transmission lines continues to increase. These trees may touch or approach high-voltage lines during their growth, causing serious accidents such as line short circuits, tripping, and even fires, which seriously threaten the safe and stable operation of the power grid. Therefore, regular pruning and felling of trees along transmission lines has become an important part of the daily maintenance work of the power department.

[0003] At present, the cutting of trees that hinder transmission lines is mainly carried out by traditional hand-held transmission saw blades, chain saws and other tools. Although these tools can meet the basic felling needs to a certain extent, they have many shortcomings and limitations:

[0004] High risk factor: When using chainsaws to fell trees, it is difficult to accurately control the direction of tree fall, so there is a risk that the tree may fall towards the operator. In addition, if the tree falls towards the side of the live line, it may trigger electric shock or arc burns, posing a serious threat to the safety of the operator.

[0005] Low work efficiency: Since traditional tools need to be operated directly by humans and need to be constantly moved and adjusted during felling, operators need to bear greater labor intensity. Long hours of work can easily lead to physical fatigue and injury, affecting work efficiency and work quality.

[0006] Low portability: In actual use, the need to carry additional fuel, batteries and other accessories, as well as the weight and volume of the tool itself, limits its portability to a certain extent. Especially in complex terrain conditions such as mountainous areas and forest areas, it increases the difficulty of carrying and using. Summary of the invention

It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0032] like Figures 1 to 5 As shown, the tree cutting device of this embodiment includes: a first housing 10, a second housing 20, a cutting mechanism 40, a first driving mechanism 50, a connecting shell 60 and a pushing mechanism 70. The second housing 20 is spaced apart from the first housing 10, and a evacuation space 30 for evading trees is formed between the front side of the second housing 20 and the front side of the first housing 10. The cutting mechanism 40 is arranged between the first housing 10 and the second housing 20, and the cutting mechanism 40 includes a first driving member 41 and a cutting member 42, and the first driving member 41 is drivingly connected to the cutting member 42 to drive the cutting member 42 to rotate. The first driving mechanism 50 is drivingly matched with the cutting mechanism 40 to move the cutting mechanism 40 along the front-rear direction of the first housing 10. The connecting shell 60 is arranged between the first housing 10 and the second housing 20 and is located at the rear side of the cutting mechanism 40. The ejection mechanism 70 is located at the rear side of the cutting mechanism 40, and the ejection mechanism 70 includes a second driving member 71 and an ejection member 72. The second driving member 71 is arranged on the connecting shell 60 and is connected to the ejection member 72 so that the ejection member 72 moves in a direction parallel to the front and rear directions of the first shell 10. The ejection member 72 has an ejection inclined surface. In the direction from the front side of the first shell 10 to the rear side of the first shell 10, the distance between the ejection inclined surface and the bottom of the first shell 10 gradually increases.

[0033] Applying the technical solution of this embodiment, the tree cutting device includes a first housing 10, a second housing 20 spaced apart from the first housing 10, a cutting mechanism 40 disposed between the first housing 10 and the second housing 20, a first driving mechanism 50 drivingly matched with the cutting mechanism 40, a connecting shell 60 disposed between the first housing 10 and the second housing 20 and located at the rear side of the cutting mechanism 40, and a pushing mechanism 70 located at the rear side of the cutting mechanism 40. An avoidance space 30 is formed between the front side of the second housing 20 and the front side of the first housing 10, and the avoidance space 30 avoids trees. The cutting mechanism 40 includes a first driving member 41 and a cutting member 42, and the first driving member 41 is drivingly connected to the cutting member 42 to drive the cutting member 42 to rotate. The first driving mechanism 50 drives the cutting member 42 to move along the front-back direction of the first housing 10. The push mechanism 70 includes a second driving member 71 disposed on the connection shell 60 and a push member 72 connected to the second driving member 71. The second driving member 71 enables the push member 72 to move in a direction parallel to the front-rear direction of the first shell 10. The push member 72 has a push slope. In the direction from the front side of the first shell 10 to the rear side of the first shell 10, the distance between the push slope and the bottom of the first shell 10 gradually increases. Through the above arrangement, the first driving member 41 drives the cutting member 42 to rotate, so that the cutting member 42 can cut the tree. The first driving mechanism 50 can drive the cutting mechanism 40 to move, so that the cutting member 42 can move in the radial direction of the tree to achieve the cutting of the tree. The connection shell 60 can connect the first shell 10 and the second shell 20. When the first driving mechanism 50 drives the cutting mechanism 40 to move toward the tree, the second driving member 71 can drive the pushing member 72 to move toward the tree, so that the pushing inclined surface of the pushing member 72 can be inserted into the crack of the tree cut by the cutting mechanism 40, so that under the action of the pushing inclined surface, the tree can have a tendency to fall in a direction away from the tree cutting device, thereby achieving control of the falling direction of the tree. Therefore, the technical solution of this embodiment effectively solves the problem that the falling direction of the tree cannot be controlled in the related art.

[0034] It should be noted that the second housing 20 has the same structure as the first housing 10 .

[0035] The angle between the push-up inclined surface and the plane perpendicular to the height direction of the first housing 10 is between 15° and 50°, specifically, 15°, 20°, 25°, 30°, 40°, 45° or 50°, and of course, other values ​​are also possible. This makes it easier for the push-up inclined surface to be inserted into the tree cleft cut by the cutting mechanism 40.

[0036] like Figure 6As shown, in this embodiment, the ejection member 72 includes an ejection block 721, and the ejection inclined surface is arranged on one side of the ejection block 721 close to the front side of the first housing 10. The ejection mechanism 70 also includes a first transmission wheel 73 rotatably arranged on the connecting shell 60 and a screw rod 74 penetrating the first transmission wheel 73. The second driving member 71 drives the first transmission wheel 73 to rotate, so as to drive the screw rod 74 to move in a direction parallel to the front-to-back direction of the first housing 10. The first end of the screw rod 74 is connected to the ejection block 721, and the second end of the screw rod 74 is a free end. The second driving member 71 can drive the first transmission wheel 73 to rotate, and the rotation of the first transmission wheel 73 can drive the screw rod 74 to move in a direction parallel to the front-to-back direction of the first housing 10, and then the screw rod 74 can drive the ejection block 721 to move.

[0037] like Figure 6 As shown, the first transmission wheels 73 include two spaced apart, the screw rods 74 include two spaced apart, and the second driving members 71 include two spaced apart. Thus, under the action of the two first transmission wheels 73 and the two screw rods 74, the ejection block 721 can be driven to move along the front-rear direction of the first housing 10.

[0038] The first transmission wheel 73 is a first bevel gear. The second bevel gear is connected to the rotating shaft of the second driving member 71, and the first bevel gear is meshed with the second bevel gear.

[0039] like Figure 4 and Figure 5 As shown, in this embodiment, the cutting member 42 includes a cutting chain 421, a second transmission wheel 422 and a third transmission wheel 423. The cutting chain 421 is sleeved outside the second transmission wheel 422 and the third transmission wheel 423. The second transmission wheel 422 is arranged on the rotating shaft of the first driving member 41. The cutting mechanism 40 also includes a connecting shaft 43 arranged on the second housing 20, and the third transmission wheel 423 is rotatably arranged on the connecting shaft 43. The rotating shaft of the first driving member 41 can drive the second transmission wheel 422 to rotate, and the rotation of the second transmission wheel 422 can drive the cutting chain 421 to rotate. The third transmission wheel 423 enables the cutting chain 421 to rotate smoothly.

[0040] The second transmission wheel and the third transmission wheel are both spur gears.

[0041] like Figure 5As shown, in this embodiment, the first driving mechanism 50 includes a third driving member 51 disposed on the first housing 10 and a fourth driving member 52 disposed on the second housing 20. The third driving member 51 is connected to the first driving member 41 so that the first driving member 41 moves along the front-rear direction of the first housing 10, and the fourth driving member 52 is connected to the connecting shaft 43 so that the connecting shaft 43 moves along the front-rear direction of the first housing 10. The third driving member 51 can drive the first driving member 41 to move along the front-rear direction of the first housing 10, and the fourth driving member 52 can drive the connecting shaft 43 to move along the front-rear direction of the first housing 10. Then, under the action of the third driving member 51 and the fourth driving member 52, the cutting member 42 can be driven to move along the front-rear direction of the first housing 10, so that the cutting member 42 can cut the tree.

[0042] like Figure 1 and Figure 3 As shown, in this embodiment, the first side of the connecting shell 60 is movably connected to the first housing 10, and the second side of the connecting shell 60 is connected to the second housing 20. The tree cutting device has a folding transport state and an unfolding working state. When the tree cutting device is in the folding transport state, the first side of the connecting shell 60 overlaps with a part of the structure of the first housing 10, and the cutting member 42 is detachably connected to the first driving member 41 and the connecting shaft 43. The tree cutting device can switch between the folding transport state and the unfolding working state, which is convenient for the tree cutting device to cut trees, or the tree cutting device is transported.

[0043] The second side of the connecting shell 60 is connected to the second outer shell 20 , which may be a fixed connection or a movable connection.

[0044] like Figure 4 As shown, in this embodiment, a receiving groove 11 is provided in the first housing 10, and the opening of the receiving groove 11 is located on the surface of the first housing 10 facing the second housing 20. When the tree cutting device is in the folded transport state, the first side of the connecting shell 60 is located in the receiving groove 11. The receiving groove 11 enables the connecting shell 60 to move into the first housing 10, and then the tree cutting device can be switched from the unfolded working state to the folded transport state.

[0045] In other embodiments, when the tree cutting device is in the folded transport state, the connecting shell 60 is located at the rear side of the first outer shell 10 .

[0046] like Figure 4 and Figure 7As shown, in this embodiment, the tree cutting device further includes a second driving mechanism 80, which includes a fifth driving member 81, a connecting rod 82 and a moving block 83. The rotating shaft of the fifth driving member 81 is provided with a screw rod 74, the moving block 83 is sleeved on the screw rod 74 and threadedly matched with the screw rod 74, the moving block 83 is vertically movably provided in the connecting shell 60, the first end of the connecting rod 82 is hingedly connected to the first housing 10, and the second end of the connecting rod 82 is hingedly connected to the moving block 83. The fifth driving member 81 can drive the screw rod 74 to rotate, and then the screw rod 74 can drive the moving block 83 to move in the connecting shell 60 along the vertical direction. When the moving block 83 moves, it can drive the connecting rod 82 to swing, and then the connecting rod 82 can drive the first housing 10 to move, so that the connecting shell 60 can enter the first housing 10 through the receiving groove 11.

[0047] It should be noted that the second driving mechanism 80 further includes a first swing rod, a first end of the first swing rod is hingedly connected to the moving block, and a second end of the first swing rod is hingedly connected to the second housing.

[0048] The second driving mechanism 80 further includes a second swing rod, a third swing rod and a block. The first end of the second swing rod is hingedly connected to the block, and the second end of the second swing rod is hingedly connected to the connecting rod. The first end of the third swing rod is hingedly connected to the block, and the second end of the third swing rod is hingedly connected to the first swing rod. The block is fixedly arranged in the connecting shell 60.

[0049] like Figure 2 and Figure 3 As shown, in this embodiment, the tree cutting device further comprises a storage structure 90 disposed on the first housing 10. When the tree cutting device is in the folded transport state, the cutting element 42 is placed on the storage structure 90. The storage structure 90 provides a placement location for the cutting element 42.

[0050] like Figure 2 and Figure 3 As shown, in this embodiment, the storage structure 90 includes a first support column 91 and a second support column 92 that are spaced apart, the second transmission wheel 422 is sleeved on the outer periphery of the first support column 91, and the third transmission wheel 423 is sleeved on the outer periphery of the second support column 92. The first support column 91 can support the second transmission wheel 422, and the second support column 92 can support the third transmission wheel 423.

[0051] It should be noted that the storage structure 90 further includes a sixth driving member, the second support column 92 is liftably disposed on the first housing 10 , and the sixth driving member is drivingly matched with the second support column 92 .

[0052] The storage structure 90 also includes a gear arranged on the rotating shaft of the sixth driving member, and a toothed plate is connected to the second support column 92. The gear engages with the toothed plate to enable the second support column 92 to rise and fall, so that the second support column 92 and the first support column 91 can support the cutting member 42 to prevent the cutting member 42 from loosening and falling.

[0053] The first driving member 41 , the second driving member 71 , the third driving member 51 , the fourth driving member 52 , the fifth driving member 81 and the sixth driving member are all driving motors.

[0054] The connecting shaft 43 is arranged on the rotating shaft of the seventh driving member. The fourth driving member 52 drives the seventh driving member to move along the front-rear direction of the first housing.

[0055] The first housing 10 includes a bottom housing and a top cover hinged to the bottom housing. The top cover is opened to facilitate the removal of the cutting member 42 .

[0056] like Figure 2 As shown, in this embodiment, the tree cutting device further includes a first walking member 100 disposed at the bottom of the first housing 10 and a second walking member 110 disposed at the bottom of the second housing 20. The tree cutting device further includes a ground support structure 120. The ground support structure 120 has a supporting state of contacting with the ground and a separation state of separation from the ground. The first walking member 100 and the second walking member 110 can drive the tree cutting device to move. The ground support structure 120 makes the position of the tree cutting device in the unfolded working state more stable.

[0057] The first walking member 100 and the second walking member 110 are both Mecanum wheels, making the device more suitable for traveling on mountain roads.

[0058] The tree cutting device of this embodiment is a U-shaped structure as a whole, and has a battery, a WiFi module and a shelf. The battery and the WiFi module are both arranged in the connecting shell 60. At least one shelf is arranged on the top of the first shell 10 and the top of the second shell 20.

[0059] The battery is arranged in the connection shell 60. A mounting box is also arranged in the connection shell 60, and the mounting box is arranged on the top of the battery. The first transmission wheel 73 is rotatably arranged in the mounting box, and a stop plate is arranged in the mounting box. The first transmission wheel 73 is arranged between the stop plate and the inner wall of the mounting box, so that when the first transmission wheel 73 rotates, the first transmission wheel 73 will not move in the axial direction of the first transmission wheel 73, so that the rotation of the first transmission wheel 73 is converted into the linear motion of the screw 74.

[0060] The second driving mechanism 80 includes two driving mechanisms symmetrically arranged on both sides of the battery.

[0061] The tree cutting device of this embodiment has the following significant advantages over other similar tree cutting devices:

[0062] (1) High safety factor: The device can be remotely controlled, and transmission personnel do not need to approach trees that are obstacles to the power lines during operation. This fundamentally eliminates the dangers of people being injured by fallen trees and arc generation caused by trees that are obstacles to the power lines accidentally touching high-voltage power lines, enabling the power grid to build an intrinsically safe enterprise.

[0063] (2) High working efficiency: The device adopts the cutting mechanism 40 to automatically cut, which effectively improves the logging efficiency and does not need to be limited by the physical strength of the power transmission personnel, thereby effectively improving the working efficiency.

[0064] (3) The direction of tree falling is controllable: The device inserts the push-up member 72 into the tree gap at a 45-degree angle and pushes the tree upward during operation, thereby controlling the direction of the tree's fall, effectively preventing the line-blocking trees from accidentally falling toward the high-voltage line side and causing arc generation and other dangers, thereby ensuring safe operation of power transmission personnel.

[0065] (4) Easy to operate: The device has a simple structure. After arriving at the work site, it only needs simple assembly to be remotely controlled to perform tree cutting work.

[0066] (5) High portability: The device is foldable when in the folded transport state, takes up little space, and can move forward on its own in steep mountain roads and woods with six Mecanum wheels equipped with independent motors, reducing the burden on power transmission personnel and effectively solving the problem of the inconvenience of carrying traditional tree cutting devices. At the same time, a shelf and a storage structure 90 are provided above the first housing 10 and the second housing 20 to facilitate the power transmission personnel to place supplies.

[0067] (6) Strong adaptability to mountain roads: The device is equipped with six Mecanum wheels, and each Mecanum wheel is independently equipped with an electric motor, which can effectively adapt to mountain conditions.

[0068] The head of the push block 721 is in a right-angled trapezoidal shape, or in a triangular shape. When working, it can be inserted into the gap between trees at a 45-degree angle and push the tree upward, thereby controlling the falling direction of the tree.

[0069] The cutting member 42 is detachable and can be detached and placed in the storage structure 90 when the device is in a folded transport state, and can be manually installed between the first driving member 41 and the connecting shaft 43 during operation.

[0070] The Mecanum wheels are symmetrically mounted on the first housing 10 and the second housing 20, and can realize forward, backward, left, right, and translational movements of the device.

[0071] The number of electric motors is the same as the number of Mecanum wheels, which provide power for the Mecanum wheels, enabling the tree cutting device to overcome rugged mountain roads and adapt to multi-terrain operations.

[0072] The second driving mechanism 80 is a scissor jack, which switches the device between an unfolded working state and a folded transport state by controlling the retraction distance of the scissor jack.

[0073] The automatic tree cutting device for power transmission line obstacles is folded and transported by line inspection personnel into the forest. The device also has a certain carrying capacity.

[0074] Since power transmission lines are usually located in mountains, with rugged roads and dense forests, ordinary logging trucks are difficult to drive, and handheld electric saws are relatively heavy, which will consume a lot of physical strength of power transmission workers. The tree cutting device of this embodiment can effectively reduce the occupied space and improve flexibility in the folded transportation state. With six Mecanum wheels equipped with independent electric motors, it can achieve forward, backward, left, right and translational movement in steep mountain roads and forests, effectively overcoming obstacles on mountain roads and reducing the burden on power transmission workers. At the same time, a storage rack is also provided for power transmission workers to place supplies conveniently.

[0075] When the transmission personnel come to the trees that are obstacles to the transmission lines, they determine the placement direction of the device according to the positions of the high-voltage wires and the trees, convert the device to the deployed working state through the second drive mechanism 80, lower the ground support structure 120 to fix it, and after installing the cutting piece 42, the transmission personnel can retreat to a safe position and perform logging operations through the mobile phone or the background remote control device.

[0076] When the device is in the expanded working state, under the control of the first driving member 41 and the third driving member 51, the cutting member 42 rotates and can move along the front-to-back direction of the first shell 10 to cut the tree. While the cutting member 42 moves forward, the second driving member 71 controls the pushing member 72 to move forward, inserts into the tree gap at a 45-degree angle and pushes the tree upward, thereby controlling the direction in which the tree falls, ensuring that the tree does not fall toward the high-voltage line side, and achieving safe tree cutting operations.

[0077] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0078] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0079] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
