Description

Technical Field

[0001] This invention relates to the field of tree radial growth measurement technology, specifically to a tree radial growth monitoring device and method. Background Technology

[0002] Radial measurement of trees provides data for landscape tree planting design, species selection, and comparison of different tree varieties. It also allows for determining the timing of planting. The radial height of a tree refers to the vertical distance from the rootstock above ground to the top of the crown. Tree height not only reflects its growth and quality but also impacts the surrounding environment. Monitoring different types of trees during landscape planting helps determine if they meet design requirements. Different types of trees of the same age can vary significantly in height; trees that do not meet design requirements should be marked. Different tree categories should also be distinguished to facilitate species selection in landscape projects and allow for additional fertilization of trees that do not meet design requirements.

[0003] The patent application CN114963934A discloses a device and method for monitoring tree height, comprising a fixed cylinder with connecting shafts connected to one end of each of its front and rear sides; both sets of connecting shafts are rotatably connected to a support assembly via bearings; a leveling device allows the base to be placed horizontally on the ground; a user stands at the recess and observes the top of the tree through the fixed cylinder; when the top is not visible, the user rotates a handwheel with their right hand, causing a lead screw to rotate, which in turn drives a sliding rod to slide on a connecting frame, causing a connecting plate to rotate the fixed cylinder by a rotating wheel at a certain angle until the user can see the top of the tree through the fixed cylinder; the height of the tree can be obtained through simple measurement and calculation; the method is simple to operate, low in cost, and easy to implement.

[0004] However, the above-mentioned device still has the following problems in its implementation: When operators adjust the rotation angle of the fixed cylinder by manually rotating the handwheel, they need to constantly adjust it to reach the measurement position. It is impossible to guarantee that the angle of the fixed cylinder can be accurately adjusted during the adjustment process, and the angle adjustment cannot be precise, resulting in redundant adjustment steps and making it impossible to adjust quickly. However, the vertical measurement of tree height is easily affected by tree branches and leaves, which cannot guarantee the accuracy of the vertical measurement of trees. At the same time, during the radial measurement, operators cannot mark and distinguish between trees that meet the requirements and those that do not. Operators are prone to confusion about specific parameters. Furthermore, when selecting different types of trees for landscaping, the measurement data of different types of trees that are not marked can vary greatly, which can lead to operators confusing the parameters of trees that do not meet the requirements, thus affecting the efficiency of horticultural tree selection. Summary of the Invention

The fixed base is installed at the top of the cylinder body, and a rotating shaft is rotatably installed inside the fixed base. The sleeve is fixedly sleeved onto the surface of the rotating shaft. A micro motor is installed on one side of the fixed base, and the output end of the micro motor is fixed to one end of the rotating shaft. A second sleeve is installed on the other side of the bottom of the connecting plate, and a connecting rod is provided inside the second sleeve. A steel cable is installed on the surface of the connecting rod. A second mounting groove is provided on the surface of the storage bin, and an annular guide rail is installed inside the second mounting groove.

[0016] Optionally, the triggering component includes:

[0017] Fixed plates are installed at intervals on the inner wall of the tube. Sliding rods are installed between adjacent fixed plates. A return spring is provided on one fixed plate and is sleeved on one end of the sliding rod. A slider is slidably sleeved on the sliding rod. The two ends of the return spring are fixed to the bottom of the slider and one end of the sliding rod, respectively. A through hole is provided at the top of one fixed plate. A steel cable passes through the through hole and is fixed to the top of the slider. A protrusion is provided on one side of the slider.

[0018] Optionally, the driving component includes:

[0019] The mounting platform is mounted on the moving end of the annular guide rail. The second limit switch is mounted on one side of the mounting platform. The top of the mounting platform has a groove, and the bottom of the groove has a direct drive guide rail. A drive plate is slidably mounted inside the groove and slides through one side of the groove. The bottom of the drive plate is fixed to the moving end of the direct drive guide rail. Limit blocks are provided on both sides of the bottom of the drive plate. The top of the drive plate has a groove, and a rotary motor is mounted on the inner wall of one side of the groove. A drive shaft is rotatably mounted through the inner wall of the other side of the groove. The output end of the rotary motor is fixed to one end of the drive shaft, and a drive column is mounted on the other end of the drive shaft. A fixed arm is provided on one side of the mounting platform, and a buffer block is mounted on one end of the fixed arm. The second limit switch is mounted on the surface of the buffer block.

[0020] Optionally, the spraying mechanism includes:

[0021] The spray plate has one end of the transmission column fixed to one side of the outer surface of the spray plate. A spray box is installed on the inner surface of the spray plate. Spray nozzles are spaced apart on the surface of the spray box. A solenoid valve is installed on the outer surface of the spray plate. The solenoid valve is connected to the spray box through a conduit. One end of the solenoid valve is connected to a feeding hose. A feeding pump is installed on the surface of the storage bin. The output end of the feeding pump is connected to one end of the feeding hose.

[0022] A method of using a tree radial growth monitoring device includes the following steps:

[0023] Step S1: Reset Process: First, the operator adds the required paint into the storage bin. The direct drive guide rail retracts the drive plate back into the groove. The adjacent spray plates are retracted under the drive of the drive plate, reducing the unfolded area and facilitating the operator's transfer and subsequent use of the device.

[0024] Step S2: Installation Procedure: When the operator needs to measure the distance to the tree, firstly, the device is moved into position using the casters at the bottom of the base. After the device is in position, the operator drives the second telescopic component, which drives the insertion rod to insert into the soil in the area where the device is located, thereby ensuring the stability of the bottom of the device.

[0025] Step S3: Distance Measurement Process: The circular guide rail is driven to rotate, causing the mounting platform to rotate. Limit switches are installed on the fixed arms between adjacent mounting platforms. When adjacent mounting platforms approach each other, the adjacent fixed arms also approach each other. The operator measures the distance between adjacent spray plates to determine the radial distance of the tree.

[0026] Step S4: Spraying process: When adjacent fixed arms approach each other, adjacent buffer blocks move closer together. The limit switch on the buffer block can trigger the limit switch when the radial value of the tree is small, thereby driving the spray head to mark the tree trunk surface in multiple positions. This makes it easier to distinguish different types of trees, avoids confusion of different tree parameters, and ensures the efficiency of horticultural tree selection.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. This invention, through the provision of the telescopic component two and the insert rod, allows for quick and stable installation of the device's bottom, preventing the device's bottom from shaking.

[0029] 2. The ranging component inside this device can measure the distance to tree heights. Once the tree data is measured, different types of trees can be marked with signals. This component has the following features:

[0030] The movement is achieved by driving a circular guide rail, which in turn rotates the mounting platform. Limit switches are installed on the fixed arms positioned between adjacent mounting platforms. When adjacent mounting platforms approach each other, the adjacent fixed arms also approach each other. The operator measures the radial distance between adjacent spray plates to determine the tree's diameter.

[0031] 3. This invention includes a triggering component that can work with a ranging component to output tree ranging signals and can also interact with a spraying component. This triggering component comprises:

[0032] When adjacent fixed arms approach each other, adjacent buffer blocks move closer together. The limit switch on the buffer block, when the radial value of the tree is small, triggers the limit switch by the mutual compression of adjacent buffer blocks, thereby driving the nozzle to mark multiple positions on the tree trunk surface. This facilitates differentiation between different types of trees, avoids confusion regarding parameters for different tree types, and ensures efficient selection of horticultural trees.

[0033] 4. The telescopic component 1 provided in this invention can drive the storage bin to move vertically when the limit switch 1 is continuously triggered, thereby increasing the spraying distance of the nozzle, so as to distinguish different types of trees, avoid confusion of different types of tree parameters, and ensure the efficiency of horticultural tree selection.

[0059] Example 5:

[0060] Based on the above embodiments:

[0061] Please see Figure 1 , Figure 2 , Figure 4 and Figure 6The ranging component includes:

[0062] The system comprises a fixed cylinder 13 and a fixed base 12. A connecting plate 122 is bolted to one side of the fixed cylinder 13. A sleeve 123 is welded to the bottom of the connecting plate 122, with the sleeve 123 positioned at the center of the bottom of the connecting plate 122. The fixed base 12 is mounted on the top of the tube body 1 via a bracket. The tube body 1 has a through groove for installation. A rotating shaft 121 is rotatably mounted inside the fixed base 12. The sleeve 123 is fixedly fitted onto the surface of the rotating shaft 121. A micro motor 127 is mounted on one side of the fixed base 12. The output end of the micro motor 127 is connected to one end of the rotating shaft 121 via a coupling, allowing the rotating end of the micro motor 127 to drive the rotating shaft 121 to rotate. A second sleeve 124 is mounted on the other side of the bottom of the connecting plate 122, and a connecting rod 125 is installed inside the second sleeve 124. The diameter of the connecting rod 125 is much smaller than the inner diameter of the sleeve 124, allowing the connecting rod 125 to slide inside the sleeve 124. The sleeves 124 are configured in two sets, spaced apart. Limiting plates (not shown in the diagram) are provided at both ends of the connecting rod 125. A steel cable 126 is installed on the surface of the connecting rod 125. The storage bin 5 has an installation groove 56 on its surface. An annular guide rail 561 is installed inside the installation groove 56. One end of the steel cable 126 is installed in the area between adjacent sleeves 124. The limiting plates are in contact with the sleeves 124 to prevent the connecting rod 125 from slipping out of the sleeves 124. The annular guide rail 561 is fitted to the inner wall of the installation groove 56, allowing the moving part on the annular guide rail 561 to smoothly move the mounting table 51 back and forth.

[0063] Example 6:

[0064] Based on the above embodiments:

[0065] Please see Figure 1 , Figure 2 , Figure 4 and Figure 6 The triggering components include:

[0066] Fixed plates 14 are spaced apart and installed on the inner wall of the pipe body 1. Slide rods 141 are installed between adjacent fixed plates 14. A return spring 143 is provided on one fixed plate 14 and is sleeved on one end of the slide rod 141. A slider 142 is slidably sleeved on the slide rod 141. The two ends of the return spring 143 are fixed to the bottom of the slider 142 and one end of the slide rod 141, respectively. When the steel cable 126 pulls the slider 142 to move, the slider 142 pulls the return spring 143 to pull. When the micro motor 127 reverses, the steel cable 126 and the slider 142 are pulled down by the return spring 143 to reset. A through hole 144 is provided on the top of a fixed plate 14. The steel cable 126 passes through the through hole 144 and is fixed to the top of the slider 142. A protrusion 1421 is provided on one side of the slider 142. The protrusion 1421 is trapezoidal, and the two sides of the trapezoidal area of ​​the protrusion 1421 are smooth, so that the protrusion 1421 can smoothly trigger and reset the limit switch 15. 1. A limit switch 15 is installed on the inner wall. Limit switch 15 is electrically connected to solenoid valve 63 and telescopic component 31 in series via external wires and power supply. Limit switch 15 and solenoid valve 63 are controlled by PLC-1200. A single trigger of limit switch 15 causes the paint to spray and triggers telescopic component 31 to rise continuously. Double trigger of limit switch 15 does not spray paint. The simple industrial programming logic involved in the scheme is well known to those skilled in the art and will not be described in detail here. When protrusion 1421 continuously triggers limit switch 15, the paint spraying action continues and the spraying distance is continuously adjusted. When protrusion 1421 disengages from limit switch 15, the paint spraying action stops and the spraying distance adjustment stops. A limit switch 8 is installed on one side of storage bin 5. When adjacent limit switches 8 touch each other and trigger, the nozzle 62 is started to perform the spraying operation. Limit switch 8 is electrically connected to solenoid valve 63 and telescopic component 31 in series via external wires and power supply.

[0067] Example 7:

[0068] Based on the above embodiments:

[0069] Please see Figure 1 , Figure 2 and Figure 3 The driving components include:

[0070] Mounting platform 51 is mounted on the moving end of annular guide rail 561. Limit switch 8 is mounted on one side of mounting platform 51. A groove 1 511 is provided on the top of mounting platform 51. A direct drive guide rail 512 is bolted to the bottom of groove 1 511. A drive plate 52 is slidably mounted inside groove 1 511, sliding through one side of groove 1 511. The bottom of drive plate 52 is fixed to the moving end of direct drive guide rail 512. Limit blocks 521 are provided on both sides of the bottom of drive plate 52. Under the drive of drive plate 52 and the moving end of direct drive guide rail 512, the limit blocks 521 slide and adhere to both sides of direct drive guide rail 512, thereby improving the stability of drive plate 52. A groove 2 522 is provided on one side of the top of drive plate 52. On the inner wall of one side of groove 2 522... A rotary motor 523 is installed, and a drive shaft 53 is rotatably installed on the inner wall of the other side of the groove 522. The output end of the rotary motor 523 is fixed to one end of the drive shaft 53 by a coupling. A drive column 54 is installed on the other end of the drive shaft 53. A fixed arm 57 is provided on one side of the mounting platform 51. A buffer block 571 is installed on one end of the fixed arm 57. The buffer block 571 is provided with a certain elasticity. Limit switches 8 are installed on the surface of the buffer block 571. Adjacent limit switches 8 will touch each other and trigger when they approach each other. When a reset is required, the direct drive rail 512 retracts the drive plate 52 and moves it, so that the drive plate 52 can retract back into the groove 511, reducing the unfolded area and making it easier for operators to transport and move the device for subsequent use.

[0071] Example 8:

[0072] Based on the above embodiments:

[0073] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 The spraying mechanism includes:

[0074] The spray plate 6 has one end of the transmission column 54 fixed to one side of the outer surface of the spray plate 6. The inner surface of the spray plate 6 is bolted with a spray box 61. The surface of the spray box 61 is provided with spray nozzles 62 at intervals, with six sets of spray nozzles. The outer surface of the spray plate 6 is equipped with a solenoid valve 63. The solenoid valve 63 is connected to the spray box 61 through a conduit. The solenoid valve 63 can supply paint to the inside of the spray box 61. One end of the solenoid valve 63 is connected to a feed hose 7. The surface of the storage bin 5 is equipped with a feed pump 55. The output end of the feed pump 55 is connected to one end of the feed hose 7. The feed pump 55 delivers paint into the inside of the feed hose 7.

[0075] Working principle: The method of using this tree radial growth monitoring device includes the following steps:

[0076] Step S1: Reset Procedure: First, the operator adds the required paint into the storage bin 5 and drives the micro motor 127 to operate. The micro motor 127 slowly releases the steel cable 126. Under the pull of the reset spring 143, the steel cable 126 resets the protrusion 1421, so that the protrusion 1421 is back in the bottom of the limit switch 15. When the limit switch 15 is reset, the direct drive rail 512 retracts the drive plate 52 back into the groove 511. The adjacent spray plates 6 are retracted under the drive of the drive plate 52, reducing the unfolded area, which makes it easier for the operator to transfer and move the device and use it later.

[0077] Step S2: Installation procedure: When the operator needs to measure the distance of the tree, first move the device into place using the casters 4 at the bottom of the base 2. After the device is in place, the operator drives the telescopic component 24, which drives the insertion rod 25 to be inserted into the soil in the area where the device is located, thereby ensuring that the bottom of the device is stable.

[0078] Step S3: Distance Measurement Process: The circular guide rail 561 is driven to rotate, causing the mounting platform 51 to rotate. Limit switches 8 are installed on the fixed arms 57 positioned between adjacent mounting platforms 51. When adjacent mounting platforms 51 approach each other, the adjacent fixed arms 57 approach each other. The operator measures the distance between adjacent spray plates 6 to determine the radial distance of the tree.

[0079] Step S4: Spraying process: When adjacent fixed arms 57 approach each other, adjacent buffer blocks 571 continuously approach each other. The limit switch 8 on the buffer block 571 can satisfy the condition that when the radial value of the tree is small, the adjacent buffer blocks 571 squeeze each other and trigger the limit switch 8, thereby driving the spray head 62 to mark the tree trunk surface in multiple positions, so as to distinguish different types of trees, avoid confusion of different types of tree parameters, and ensure the efficiency of horticultural tree selection.

7. A method of using a tree radial growth monitoring device, based on the tree radial growth monitoring device according to any one of claims 4-6, characterized in that, Includes the following steps: Step S1: Reset process: First, the operator adds the required paint into the storage bin (5). The direct drive rail (512) retracts the drive plate (52) back into the groove (511). The adjacent spray plates (6) are pulled together by the drive plate (52) to reduce the unfolded area, making it easier for the operator to transfer and move the device and use it later. Step S2: Installation process: When the operator needs to measure the distance of the tree, the device is first moved into place by the universal wheels (4) at the bottom of the base (2). After the device is moved into place, the operator drives the telescopic part two (24), and the telescopic part two (24) drives the insertion rod (25) to be inserted into the soil in the area where the device is located, thereby ensuring that the bottom of the device is stable. Step S3: Distance measurement process: The circular guide rail (561) is driven to move, and the circular guide rail (561) drives the mounting platform (51) to rotate. The fixed arm (57) between the adjacent mounting platforms (51) is equipped with limit switch two (8). When the adjacent mounting platforms (51) are close, the adjacent fixed arms (57) are close. The operator measures the distance between the adjacent spray plates (6) to measure the radial data of the tree. Step S4: Spraying process: When adjacent fixed arms (57) approach each other, adjacent buffer blocks (571) continuously approach each other. The limit switch (8) on the buffer block (571) is triggered when the radial value of the tree is small. The adjacent buffer blocks (571) squeeze each other to trigger the limit switch (8), thereby driving the nozzle (62) to mark the tree trunk surface in multiple positions so as to distinguish different types of trees, avoid confusion of different types of tree parameters, and ensure the efficiency of horticultural tree selection.
