Description

Technical Field

[0001] The invention relates to the technical field of fruit tree cultivation, and in particular to a fruit tree branch angle control device. Background Art

[0002] The branching angle of a fruit tree branch refers to the angle between the trunk or main branch and the branch, and is one of the important parameters of the fruit tree's morphological structure. In the process of raising fruit trees, a reasonable branching angle is crucial to the healthy growth of the tree. A suitable angle can not only improve the ventilation and light transmission conditions of the tree and promote photosynthesis, but also enhance the bearing capacity of the branches, effectively improving the quality and yield of the fruit.

[0003] In addition, a reasonable branching angle can reduce the risk of branch breakage and lay a good foundation for the subsequent growth of fruit trees.

[0004] In actual fruit tree seedling cultivation, the branching angle needs to be optimized according to the characteristics of different tree species during the cultivation process, and the branch distribution needs to be adjusted to form an ideal tree structure. This process requires both accurate measurement of the branching angle and timely adjustment of unreasonable branch growth directions.

[0005] The traditional seedling cultivation method mainly relies on manual observation and measurement. The specific operations include using a protractor or measuring ruler to check the branching angles of the branches one by one, and bundling, supporting or pulling the branches that do not meet the requirements. Although this method can achieve certain effects, due to the large number of fruit trees and complex branches, manual measurement and adjustment are time-consuming and labor-intensive.

[0018] Compared with the prior art, the present invention provides a fruit tree branch angle control device, which has the following beneficial effects:

[0019] 1.

The initial state is perpendicular to the fixed plate and parallel to the clamp to ensure the initial reference. The flip motor drives the rotating plate to rotate so that it gradually unfolds along the branching direction of the fruit tree branch and is adjusted to a position parallel to the target branch in real time. The distance measuring device is installed at the end of the rotating plate. As the rotating plate rotates, it continuously records the real-time distance and angle changes between it and the forked branch. During the flipping process of the rotating plate, the angle sensor and the distance measuring device work together to record the rotation angle between the rotating plate and the fixed plate and the distance from the forked branch.

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0036] Example:

[0037] Reference Figure 1 - Figure 8 A fruit tree branch angle control device comprises a clamp 1 for clamping and fixing a fruit tree branch, and also comprises: an angle distance measuring member 3 fixedly mounted on one side of the clamp 1, wherein the angle distance measuring member 3 comprises a distance measuring member 303 for measuring the distance between itself and a forked branch of the fruit tree branch, and two distance measuring members 303 are provided, and the two distance measuring members 303 correspond to two forked branches of the fruit tree branch, and the initial positions of the two distance measuring members 303 are parallel to the clamp 1. When measuring the angle between the two forked branches of the fruit tree branch, the two distance measuring members 303 perform a flipping distance measurement operation with the clamp 1 as the axis; a control board is arranged inside the clamp 1, and the control board is electrically connected to the measuring member, and the control board completes the three-dimensional composition measurement of the fruit tree branch through the real-time angle of the two measuring members and the real-time measurement distance of the two measuring members, and the control board calculates the angle between the two forked branches of the fruit tree branch.

[0038] In the above-mentioned fruit tree branch angle control device, the operator moves to the vicinity of the target fruit tree branch and clamps the main branch where the bifurcation point is located into the clamp 1. The clamp 1 fixes the fruit tree branch through an automatic clamping mechanism to ensure that the device is stable and avoid errors caused by looseness during the measurement process. The two distance measuring members 303 are initially parallel to the clamp 1 to ensure that the reference for the initial measurement is unified. The two distance measuring members 303 begin to flip around the clamp 1 as the axis. The distance measuring members 303 record the change in the distance between them and the bifurcation branch in real time. During the flipping process of the distance measuring members 303, the control panel monitors the flipping angle of the distance measuring members 303 in real time and records the rotation position of each distance measuring member 303.

[0039] The control board receives the angle information and the corresponding distance data of the two distance measuring components 303, and uses the relative position of the bifurcated branches and the main branch to construct a three-dimensional spatial model of the bifurcation point. The control board calculates the angle between the two bifurcated branches based on the three-dimensional model, and further optimizes the measurement angle according to the measured length, thereby avoiding the problem of inaccurate angle measurement when the traditional device is tilted for measurement.

[0040] Finally, the control panel displays the measurement results, including the bifurcation angle and three-dimensional structure diagram, through a display screen or other output devices. If the bifurcation angle exceeds the reasonable range, an alarm is issued. The user can also limit the bifurcation through the clamp 1, and then tie the cable tie to correct the constraint. The measurement data can be stored in the internal storage unit or transmitted to the orchard management system through the wireless communication module to achieve long-term monitoring of the growth status of the fruit trees. This avoids the tediousness of manual measurement one by one and improves the detection efficiency of the bifurcation angle of the fruit tree branches.

[0041] In order to measure the angle change of the fruit tree branches from the intersection to the distance, the angle measuring component 3033 further includes a fixed plate 301, a rotating plate 302 is rotatably installed on the upper part of the fixed plate 301, a flip motor 304 is fixedly installed on one side of the fixed plate 301, and the output end of the flip motor 304 electrically connected to the control board is fixedly connected to the rotating shaft of the rotating plate 302.

[0042] The rotating plate 302 is controlled by a flipping motor 304. In its initial state, it is perpendicular to the fixed plate 301 and parallel to the clamp 1 to ensure the initial reference. The flipping motor 304 drives the rotating plate 302 to rotate, so that it gradually unfolds along the branching direction of the fruit tree branches and is adjusted in real time to a position parallel to the target branch. The distance measuring component 303 is installed at the end of the rotating plate 302. As the rotating plate 302 rotates, it continuously records the real-time distance and angle changes between it and the forked branches. During the flipping process of the rotating plate 302, the angle sensor and the distance measuring component 303 work together to record the rotation angle between the rotating plate 302 and the fixed plate 301 and the distance from the forked branches. The flipping motor 304 controls the rotation angle so that the rotating plate 302 can cover the range from the intersection to the distant target position.

[0043] In order to achieve the angle change of the distance measuring member 303, further, a slide rail 309 is fixedly connected to the upper part of the rotating plate 302, two sliders 308 are slidably installed on the upper part of the slide rail 309, and a distance measuring member 303 is rotatably installed on the upper part of each slider 308. In order to achieve the angle change of the infrared rangefinder 3033 by using the slider 308, further, the distance measuring member 303 includes a support plate 3031, the support plate 3031 is rotatably installed on the upper part of the slider 308, two limit plates 3032 are fixedly connected to the lower part of the support plate 3031, the limit rod 310 is fixedly connected to the upper part of the rotating plate 302, the head of the limit rod 310 is slidably inserted between the two limit plates 3032, and the infrared rangefinder 3033 is fixedly installed on the upper part of the support plate 3031. In order to realize the synchronous swinging scanning of the fruit tree branches by the two distance measuring members 303, further, a driven gear 305 is rotatably mounted on the upper part of the rotating plate 302, and two driven gears 305 are provided, and the two driven gears 305 are meshed and connected, and a fixed rod 306 is fixedly connected to the upper part of each driven gear 305, and a connecting rod 307 is provided on the outer sliding sleeve of the fixed rod 306, and the connecting rod 307 is fixedly connected to the slider 308. In order to realize the driving of the two driven gears 305, further, one of the driven gears 305 is meshed and connected with a driving gear 311, and the driving gear 311 is rotatably mounted on the upper part of the mounting plate.

[0044] In order to realize the angle change and synchronous swing of the distance measuring element 303, the design introduces a slide rail 309, a slider 308, a limit structure and a gear linkage mechanism, so that the infrared distance measuring element 303 can swing back and forth along the branch direction of the fruit tree branch to complete an efficient scanning operation.

[0045] The driving gear 311 meshes with a driven gear 305; the two driven gears 305 are meshed and connected to form a linkage mechanism. A fixed rod 306 is fixedly connected to each driven gear 305. A connecting rod 307 is slidably sleeved outside the fixed rod 306. The connecting rod 307 is fixedly connected to the slider 308 to form a slider 308 driving structure. The fixed rod 306 of each driven gear 305 drives the slider 308 to slide left and right on the slide rail 309 through the connecting rod 307. The two sliders 308 always keep synchronization, but move in opposite directions to ensure that the infrared rangefinder 3033 swings symmetrically.

[0046] When the slider 308 slides along the slide rail 309, the infrared rangefinder 3033 realizes synchronous left and right swing along with the support plate 3031. The infrared rangefinder 3033 maintains synchronous swing through gear linkage, covering both sides of the branch of the fruit tree, completing a comprehensive scan of the target area. The infrared rangefinder 3033 obtains the distance data of the target branch in real time, and records the measurement value of each swing angle through the control panel.

[0047] In order to realize the rotation of the rotating plate 302, the driving wheel can be driven to rotate at a variable speed, the lower part of the driving gear 311 passes through the rotating plate 302 and is fixedly connected to the first bevel gear 312, the first bevel gear 312 is meshedly connected to the second bevel gear 313, the second bevel gear 313 is rotatably installed at the lower part of the rotating plate 302, one side of the second bevel gear 313 is fixedly connected to a rotating rod 314, the end of the rotating rod 314 away from the second bevel gear 313 is fixedly connected to a contact gear 315, one side of the fixed plate 301 is fixedly connected to an arc-shaped rack 316, and the inner side of the arc-shaped rack 316 is movably meshed with the contact gear 315.

When the rotating plate 302 rotates, the contact gear 315 rotates around its own axis and engages with the inner side of the arc-shaped rack 316 fixedly installed on one side of the fixed plate 301, thereby driving the second bevel gear 313 to drive the first bevel gear 312 to rotate, completing the driving gear 311, and realizing the control of the swing scanning of the two distance measuring parts 303 while flipping the rotating plate 302.

[0049] To realize the electric drive control and switch 2 control based on the control board, the clamp 1 further includes a handle 101, the control board is integrated and installed inside the handle 101, and the switch 2 fixedly installed on one side of the handle 101 is electrically connected to the control board. To realize the clamping action of the first clamping plate 102 and the second clamping plate 103, further, the first clamping plate 102 is fixedly connected to one side of the handle 101, the second clamping plate 103 is slidably installed on the side of the first clamping plate 102 away from the handle 101, and the screw rod 107 rotatably installed on one side of the handle 101 is screwed to the second clamping plate 103. In order to realize the clamping action of the electrically driven first clamping plate 102 and the second clamping plate 103, further, the clamping motor 109 fixedly installed at one end of the handle 101 is electrically connected to the control board, and the output end of the clamping motor 109 is fixedly connected to the large pulley 104, and the small pulley 106 rotatably installed on the handle 101 is connected to the large pulley 104 through the transmission belt 105, one side of the small pulley 106 is fixedly connected to the screw rod 107, and the outside of the screw rod 107 is screwed with a slide plate 108, one side of the slide plate 108 is fixedly connected to the second clamping plate 103, and the slide plate 108 is slidably connected to the first clamping plate 102.

[0050] For the electric drive clamping mechanism of the clamp 1, the clamping action of the first clamping plate 102 and the second clamping plate 103 is realized through the control panel, the clamping motor 109 and the mechanical transmission device. The user triggers the control signal through the switch 2 installed on one side of the handle 101, and the switch 2 transmits the command to the control panel inside the handle 101. The control panel controls the start, stop and rotation direction of the clamping motor 109 according to the signal. The control panel receives and processes the switch 2 command, drives the clamping motor 109 to operate according to the preset mode, such as clamping or loosening action. After the clamping motor 109 is started, its output end drives the large pulley 104 to rotate through the transmission shaft. The large pulley 104 is connected to the small pulley 106 through the transmission belt 105, and the power is transmitted to the small pulley 106. The small pulley 106 is fixedly connected to the screw rod 107. When the small pulley 106 rotates, it drives the screw rod 107 to rotate synchronously.

The slide plate 108 is fixedly connected to the second clamping plate 103, and during the sliding process of the slide plate 108, the second clamping plate 103 is driven to move closer to or farther from the first clamping plate 102. The slide plate 108 is slidably connected to the first clamping plate 102 to ensure the smooth movement of the second clamping plate 103, and to perform clamping or loosening actions.

[0051] In the present invention, the operator moves to the vicinity of the target fruit tree branch and clamps the main branch where the bifurcation point is located into the clamp 1. The clamp 1 fixes the fruit tree branch through an automatic clamping mechanism to ensure that the device is stable and avoid errors caused by looseness during the measurement process. The two distance measuring parts 303 are initially parallel to the clamp 1 to ensure that the reference for the initial measurement is unified. The two distance measuring parts 303 begin to flip around the clamp 1 as an axis. The distance measuring parts 303 record the distance changes between them and the bifurcation branches in real time. During the flipping of the distance measuring parts 303, the control panel monitors the flipping angle of the distance measuring parts 303 in real time and records the rotation position of each distance measuring part 303. The control panel receives the angle information of the two distance measuring parts 303 and the corresponding distance data. Using the relative position of the bifurcation branch and the main branch, the control panel constructs a three-dimensional spatial model of the bifurcation point. The control panel calculates the angle between the two bifurcation branches based on the three-dimensional model, and further optimizes the measurement angle according to the measured length to avoid the problem of inaccurate angle measurement when the traditional device is tilted for measurement.
