DETAILED DESCRIPTION

[0034] In order to better understand the present application, the following examples are described in conjunction with the drawings, which are within the scope of the present application, but do not limit the scope of the present application.

[0035] Example 1

[0036] ​A type of tree climbing and pruning machine with opposed drive wheels, such as Figures 1-5 As shown, it includes:

[0037] A fixed support 1 is arranged around one side of the tree trunk 01; a movable support 2 is arranged opposite the fixed support 1 on the other side of the tree trunk 01; a drive assembly 3 provides power for the tree climbing and pruning machine to climb and fall; it includes a first drive wheel 31 and a second drive wheel 32, the first drive wheel 31 being located at one end of the fixed support 1 and the second drive wheel 32 being located at one end of the movable support 2; the first drive wheel 31 and the second drive wheel 32 can roll up and down along the outside of the tree trunk 01; a pruning blade assembly 4 is used to prune branches; it includes a blade holder 41, a fixed blade 42, a movable blade 43, and a rotating device 44; the fixed blade 42 is respectively arranged opposite to the fixed support 1 and the movable support 2. At the top of the support 2, there are N movable blades 43, where N is a positive integer, located on the fixed support 1 and distributed on both sides of the fixed blade 42; the blade support 41 is located at the top of the fixed support 1, and the rotating device 44 is located at the top of the blade support 41 and is gear-connected to the movable blade 43; the adjusting assembly 5 is used to adjust the distance between the movable support 2 and the fixed support 1; it includes a telescopic device 51, a movable rod 52, and an adjusting plate 53; the telescopic device 51 is distributed on both sides of the fixed support 1, and the telescopic device 51 has a movable rod 52, the end of which is connected to the adjusting plate 53 on the same side; the movable support 2 is located on the adjusting plate 53.

[0038] This tree climbing and pruning machine is powered by an external power source. The specific power supply method can be selected from generators, batteries, or mains power as needed. For example, a small generator can be used to generate electricity to power the first drive wheel, second drive wheel, rotating device, telescopic device, and detection components, ensuring normal operation. The small generator is not too heavy, making it easy to move to different positions during pruning operations.

[0039] The first and second drive wheels can be equipped with hub-mounted geared motors, which have internal gear reduction mechanisms to reduce speed and increase torque.

[0040] The fixed blade and the movable blade have their cutting edges facing upwards, and the cutting edge position can be set as an arc-shaped structure; reinforcing ribs can be set on the outer side of the arc of the cutting edge to improve the durability of the cutting edge.

[0041] A fixed blade and a movable blade are provided on one side of the fixed bracket. To make the positions of the fixed blade and the movable blade more reasonable, the fixed blade can be placed on the top of the blade bracket, and the movable blade can be placed on the top of the fixed bracket below the blade bracket, so that the movable blade can be connected to the gear of the rotating device on the blade bracket.

[0042] The fixed blade and the movable blade are not in the same horizontal plane; in the drawings, the fixed blade is above the movable blade, one end of the movable blade is provided with an internal gear for engaging with an external gear of the rotating device, so that when the rotating device is reversed, the movable blade can be controlled to expand / close; the rotating device can use a motor.

[0043] N = 2, that is, the movable blade is provided with two pieces; in this way, the fixed blade is provided with two pieces, which are arranged on the fixed support and the movable support; the movable blade is provided with two pieces, which are arranged on the fixed support; since the movable blade is rotated by the external gear of the rotating device, the two movable blades should be arranged in sequence from top to bottom, so that the rotating device can be operated to control the expansion or closure of the two movable blades.

[0044] The movable support and the adjusting plate are movably connected, so that when a trunk starts to be worked or is completed, the movable support and the adjusting plate can be separated, so that the fixed support can be mounted on the trunk or removed from the trunk; the movable connection mode can be pin connection, threaded connection, etc.

[0045] The movable rod is not necessarily provided, and can be selected as needed. Because the telescopic device itself includes a telescopic rod, when the length of the telescopic rod meets the use requirement, the movable rod need not be provided, and at this time, the pull rod is arranged at the end of the telescopic rod; when the length of the telescopic rod does not meet the use requirement, the movable rod can be provided.

[0046] The use method is as follows: when pruning work starts, the movable support and the adjusting plate are separated, at this time, the movable rod is in the extended state and the movable blade is in the expanded state; the fixed support is clamped at the bottom of the trunk at a suitable position, at this time, the first driving wheel is attached to the trunk bark; then the movable support is connected to the adjusting plate through the pin, at this time, the trunk is in the area enclosed by the fixed support and the movable support; the rotating device is controlled to close the movable blade, so that the cutting edges of the movable blade are attached to the trunk surface; the telescopic device is controlled to retract the movable rod until the second driving wheel is attached to the trunk bark; at this time, the fixed blade and the movable blade of the tree climbing pruning machine are attached to the trunk bark. Subsequently, the first driving wheel and the second driving wheel are controlled to roll upward, and pruning work can be performed.

[0047] After the pruning work is completed, the first driving wheel and the second driving wheel are controlled to roll downward to a suitable position close to the ground, and then the first driving wheel and the second driving wheel are turned off; the rotating device is controlled to operate, and the movable blade is expanded outward; the telescopic device is controlled to extend the movable rod outward; the pin connecting the movable support and the adjusting plate is removed, so that the movable support and the adjusting plate can be separated, and then the fixed support can be removed.

[0048] The above operation is repeated to perform pruning work on the next trunk.

[0049] Example 2

[0050] As Figures 1-5 shown, the tree pruning machine of the present application further has the following technical features:

[0051] The two sides of the fixed support 1 are provided with guide rails 11, the guide rails 11 are provided with sliding blocks 12, and the sliding blocks 12 are connected with the end portions of the adjusting plates 53.

[0052] The adjusting assembly 5 further comprises through holes 54, elastic members 55 and pull rods 56; the adjusting plates 53 are provided with the through holes 54 relative to the positions of the movable rods 52, the hollow elastic members 55 are arranged on the sides of the through holes 54 away from the movable rods 52, and the pull rods 56 are connected with the end portions of the movable rods 52 through the elastic members 55; the width of the elastic members 55 is greater than the diameter of the through holes 54.

[0053] The guide rails arranged on the two sides of the fixed support can be 4, symmetrically arranged, one on the upper side and one on the lower side of each side, and fixedly arranged on the side surfaces of the fixed support.

[0054] The elastic member can be a spring, and the present application specifically uses a spiral compression spring; since the outer diameters of different tree trunks or different heights of the same tree trunk are different, the guide rails are arranged to facilitate the telescopic adjustment of the movable support, so that the movable rod extends or retracts when the telescopic device operates, and the adjusting plate performs corresponding actions; the arranged elastic member has a buffering effect and can reduce the shaking of the movable support during adjustment.

[0055] Example 3

[0056] As Figures 1-5 shown, the tree pruning machine of the present application further has the following technical features:

[0057] The area surrounded by the vertical projections of the fixed blade 42 and the movable blade 43 is the same as the outer diameter of the tree trunk 01.

[0058] The driving assembly 3 further comprises a driven wheel 33, the driven wheel 33 can roll up and down on the outer side of the tree trunk 01; the driven wheel 33 is arranged on the side surface of the fixed support 1 and below the first driving wheel 31; the driven wheel 33 is arranged parallel to the first driving wheel 31 and the second driving wheel 32.

[0059] The outer sides of the first driving wheel 31, the second driving wheel 32 and the driven wheel 33 are provided with soft layers 34, and the soft layers 34 are in contact with the tree trunk 01 when the first driving wheel 31, the second driving wheel 32 and the driven wheel 33 roll up and down.

[0060] The thickness of the soft layer 34 is 10-30mm, and the hardness is 40-65HA; specifically, rubber, silicone or the like can be selected as the soft layer.

[0061] The soft layer is arranged to avoid damaging the tree bark when the tree pruning machine climbs, and the thickness and hardness of the soft layer are required to improve the durability. The connection mode of the soft layer with the first driving wheel, the second driving wheel and the driven wheel can be selected to be adhesive. After the soft layer is damaged and affects the use, the soft layer can be removed and replaced with a new one.

[0062] Embodiment 4

[0063] As shown in Figure 6 The tree pruning machine also has the following technical features:

[0064] The tree pruning machine also includes a detection assembly 6 arranged on the fixed support 1, and the detection assembly 6 includes a state detection unit 61, a position detection unit 62, a control unit 63, a transmission unit 64 and a remote terminal 65. The state detection unit 61 is used to detect the running state of the first driving wheel 31, the second driving wheel 32, the rotating device 44 and the telescopic device 51. The position detection unit 62 is used to detect the geographical position of the tree pruning machine. The control unit 63 is used to control the start and stop of the first driving wheel 31, the second driving wheel 32, the rotating device 44 and the telescopic device. The transmission unit 64 is used to collect and transmit the information of the state detection unit 61 and the position detection unit 62 to the remote terminal 65. The remote terminal 65 is in communication connection with the control unit 63.

[0065] A sensor 35 is arranged between the adjusting plate 53 and the elastic member 55, and the pull rod 56 passes through the sensor 35. The sensor 35 is in electrical connection with the control unit 63. When the pressure monitored by the sensor 35 reaches a preset value, the telescopic device 51 is controlled to stop running by the control unit 63.

[0066] When the telescopic device is started, the movable rod is retracted, the adjusting plate moves along the track towards the first driving wheel, the movable rod bears the tension, and the sensor arranged in the movable rod is also subjected to the corresponding force. When the first driving wheel moves to the appropriate position, the pressure monitored by the sensor reaches the preset value. At this time, the signal information of the sensor is transmitted to the control unit, and the telescopic device is controlled to stop running by the control unit, so that the adjustment and use of different tree trunk diameters are realized.

[0067] The sensor can be a tension sensor.

[0068] Through the use of the state detection unit, the position detection unit, the control unit, the transmission unit and the remote terminal in the detection assembly, when the tree pruning machine is pruning the tree trunk, the number of pruned tree trunks and the position of the pruned tree trunks can be obtained without the need for the operator to look after, thereby improving the convenience of management.

[0069] The state detection unit, the position detection unit, the control unit and the transmission unit are all connected with an external power supply to meet the power demand during operation.

[0070] The position detection unit can use a chip with positioning function based on GPS, Beidou, etc.

[0071] The control unit can be a single-chip microcomputer, which functions to control the running state of the electrical components, receive the information fed back by the state detection unit and the position detection unit, and transmit the information to the remote terminal through the transmission unit; the electrical components are specifically: the first driving wheel, the second driving wheel, the rotating device, the telescopic device, etc.
