[0035] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0036] Combination Figures 1 to 4 As shown, this embodiment of the present disclosure provides a tree branch angle measuring device, including a U-shaped plate 1, a first rotating shaft 2, a pendulum 3, a scale dial 4, a pointer 5, a strip plate 6, a first support 7, a roller 8, and a driving component. The first rotating shaft 2 is rotatably disposed along the width direction of the U-shaped plate 1, passing through opposite side walls of the U-shaped plate 1, and can rotate relative to the U-shaped plate 1. The pendulum 3 is mounted on the first rotating shaft 2 and located inside the U-shaped plate 1, used to drive the first rotating shaft 2 to rotate. The scale dial 4 is mounted on one of the opposite side walls of the U-shaped plate 1 and located outside the U-shaped plate 1, used to display scale values. The pointer 5 is mounted on the first rotating shaft 2, located outside the U-shaped plate 1, and points to the scale dial 4, rotating under the drive of the first rotating shaft 2. Strip plates 6 are located on the outer side of the gable plate 1, along the width direction of the gable plate 1, on both sides of the gable plate 1. The planes of the two strip plates 6 are parallel to each other and are used to support the installation of the first supports 7. The first supports 7 are respectively installed on the opposite surfaces of the two strip plates 6, and are located at both ends of each strip plate 6, respectively, and are used to support the installation of rotatable rollers 8. The rollers 8 are respectively installed on each of the first supports 7 on both sides, and the axis of each roller 8 is perpendicular to the axis of the first rotating shaft 2, and are used to abut against the tree branches. A driving component is installed between the gable plate 1 and the two strip plates 6 to provide driving force and drive the two strip plates 6 to move towards or away from each other. Under the drive of the driving component, the two rollers 8 clamp or release the tree branches.

[0037] This disclosure provides a tree trunk and branch angle measuring device. By controlling the drive mechanism, the two side strip plates 6 can move towards or away from each other. This, in turn, drives the two side first supports 7 to move towards or away from each other, ultimately causing the two side rollers 8 to clamp the trunk or main branch of the tree. Then, under the action of gravity, the pendulum 3 drives the first rotating shaft 2 to deflect, which in turn drives the pointer 5 to deflect. Finally, the tilt angle of the tree trunk or main branch can be calculated based on the scale value indicated by the pointer 5. The operation is simple and convenient for measuring the tilt angle of the tree trunk or main branch. Furthermore, since the two side rollers 8 can rotate relative to the two side first supports 7, after the device is clamped onto the tree trunk or main branch, it can still be pushed to rotate relative to the tree trunk or main branch, thereby measuring the tilt angle of the tree trunk or main branch in different directions.

[0038] Optionally, combined Figure 3As shown, the driving member includes the L-shaped plate 9, the guide rail 10, the sliding block 11, the bent plate 12, the screw nut 13 and the ball screw 14. The L-shaped plate 9 is connected to the top surface of the L-shaped plate 1. The guide rail 10 is installed on the inner side surface of the L-shaped plate 9 along the width direction of the L-shaped plate 1, and is used to support the installation of the slidable sliding block 11. The sliding block 11 is installed on the guide rail 10 and is located on both sides of the L-shaped plate 1 along the width direction of the L-shaped plate 1. The guide rail 10 and the two sliding blocks 11 jointly function as a guide support. The bent plate 12 is installed on the two sliding blocks 11 respectively, and the two strip-shaped plates 6 are installed on the two bent plates 12 respectively. Under the guide and support of the guide rail 10 and the two sliding blocks 11, the two strip-shaped plates 6 move along the length direction of the L-shaped plate 1. The screw nut 13 is installed on the two bent plates 12 respectively, and is used to drive the movement of the two bent plates 12 respectively. The ball screw 14 is installed inside the two screw nuts 13 respectively. The axes of the two ball screws 14 coincide with each other, and are parallel to the axis of the first rotating shaft 2. The two ball screws 14 are used to convert the rotary motion into linear motion. Among them, the two ball screws 14 are controlled to rotate, so that the two strip-shaped plates 6 move towards or reversely.

[0039] In the embodiment of the present disclosure, the two ball screws 14 are driven by external force to rotate, and then under the guide and support of the guide rail 10 and the two sliding blocks 11, the two screw nuts 13 drive the two bent plates 12 to move towards or reversely. Further, the two strip-shaped plates 6 are driven to move towards or reversely, and finally the two rollers 8 clamp the main stem and main branches of the tree.

[0040] Optionally, in combination with Figure 1 and Figure 4 As shown, the driving member further includes the second support 15, the second rotating shaft 16, the driving bevel gear and the driven bevel gear. The second support 15 is installed on the top surface of the L-shaped plate 9, and is used to support the installation of the rotatable second rotating shaft 16. The second rotating shaft 16 is rotatable and penetrates through the second support 15 along the height direction of the L-shaped plate 1, and can rotate relative to the second support 15. The driving bevel gear is installed at the bottom end of the second rotating shaft 16, and rotates under the driving of the second rotating shaft 16. The driven bevel gear is installed on the two ball screws 14 respectively, and is used to drive the rotation of the two ball screws 14 respectively. The two driven bevel gears are engaged with the driving bevel gear, and are used to transmit driving force and change the direction of the force. Among them, the second rotating shaft 16 is controlled to rotate, so that the two ball screws 14 rotate simultaneously.

[0041] In the embodiment of the present disclosure, the second rotating shaft 16 is driven to rotate by external force, and then drives the driving bevel gear to rotate. Through the meshing action between the teeth, the two driven bevel gears are driven to rotate. Further, the two ball screws 14 are driven to rotate simultaneously, and finally the two rollers 8 clamp the main stem and main branches of the tree.

[0042] Optionally, in combination with Figure 1 and Figure 4As shown, the driving member further comprises a hand wheel 17. The hand wheel 17 is mounted on the top end of the second rotating shaft 16.

[0043] In the embodiments of the present disclosure, the hand wheel 17 is used for holding, so as to manually drive the second rotating shaft 16 to rotate.

[0044] Optionally, in combination with Figure 1 and Figure 4 As shown, the driving member further comprises a handle fixing ring 18. The handle fixing ring 18 is mounted on the support and is sleeved on the second rotating shaft 16.

[0045] In the embodiments of the present disclosure, the handle fixing ring 18 is used for clamping or loosening the second rotating shaft 16. When the handle fixing ring 18 loosens the second rotating shaft 16, the positions of the two side rollers 8 can be adjusted. When the handle fixing ring 18 clamps the second rotating shaft 16, the two side rollers 8 can be prevented from loosening.

[0046] Optionally, in combination with Figure 1 and Figure 4 As shown, the driving member further comprises a first bearing. The first bearing is sleeved on the second rotating shaft 16 and is mounted on the support.

[0047] In the embodiments of the present disclosure, the first bearing is used for reducing the friction between the second rotating shaft 16 and the second support 15 and improving the accuracy when the second rotating shaft 16 rotates relative to the second support 15.

[0048] Optionally, in combination with Figure 3 As shown, the driving member further comprises linear bearings 19, guide shafts 20, limit rings 21 and springs 22. The linear bearings 19 are mounted on the two side bending plates 12 along the width direction of the frame 1, respectively, and are used for supporting the slideable guide shafts 20. The guide shafts 20 are mounted in the linear bearings 19, respectively, and the opposite ends of the two guide shafts 20 are connected with the two side strip plates 6, respectively, and are used for guiding and supporting, so that the two limit plates move along the width direction of the frame. The limit rings 21 are mounted on the other ends of the two guide shafts 20, respectively, and are used for limiting, so as to prevent the two guide shafts 20 from falling off the two optical axes. The springs 22 are sleeved on the two guide shafts 20, respectively, and are located between the two side strip plates 6 and the two side bending plates 12, respectively, and are used for providing elastic force.

[0049] In the embodiments of the present disclosure, when the two side rollers 8 are behind the trunk or main branch of the tree, the two springs 22 can be compressed under the guiding and supporting of the two guide shafts 20. At this time, the elastic force generated by the deformation of the two springs 22 can be converted into clamping force on the trunk or main branch of the tree. In this way, the damage to the bark of the tree caused by excessive clamping force can be avoided. In addition, the whole device can be pushed to rotate relative to the trunk or main branch of the tree.

[0050] Optionally, in combination with Figure 1 and Figure 3 As shown in the figure, the driving member further comprises a second belt seat bearing. The second belt seat bearing is sleeved on the two side ball screws 14 respectively and is installed on the opposite two side walls of the L-shaped plate 9.

[0051] In the embodiment of the present disclosure, the two second belt seat bearings are used to improve the stability of the two side ball screws 14, so that the two side ball screws 14 can rotate smoothly.

[0052] Optionally, in combination with Figure 2 As shown in the figure, the driving member further comprises a third belt seat bearing. The third belt seat bearing is installed on the other one of the opposite two side walls of the L-shaped plate 1 and is located outside the L-shaped plate 1.

[0053] In the embodiment of the present disclosure, the third belt seat bearing is used to reduce the friction between the first rotating shaft 2 and the L-shaped plate 1 and improve the accuracy when the first rotating shaft 2 rotates relative to the L-shaped plate 1.
