Description

Technical Field

[0001] The utility model relates to the technical field of forest farm tree management, and specifically relates to a device for measuring the diameter of forest farm trees, painting lime, and counting positions. Background Art

[0002] Forest farm management includes work such as forest resource management and pest control management. In forest resource management work, it generally includes the direct measurement and statistics at a specific height of the tree trunk. At present, the direct measurement at the corresponding position of the tree trunk is carried out manually using a flexible ruler. This measurement method has low efficiency and high manual labor intensity; in pest control management work, it is generally necessary to paint lime on trees in winter. At present, there are some automatic devices for painting lime on trees on the market. However, the price of the device is relatively high and the structure is relatively complex, which is not convenient for maintenance and repair. At the same time, in some areas, manual painting of lime is still used. Manual painting of lime is to smear lime slurry on the tree trunk little by little by hand. This method not only has low work efficiency but also high labor intensity. Content of the Utility Model

The controller is electrically connected to the GPS locator, the radar ranging sensor, and the laser rangefinder. The flexible spraying pipe is arranged below the annular frame with an opening formed by the semi-circular support seat, the left opening and closing arm, and the right opening and closing arm. Both ends of the flexible spraying pipe are in a closed state. A number of nozzles are arranged at equal intervals on the side wall of the flexible spraying pipe, and the liquid outlet of each nozzle points to the center of the semi-circular support seat. The lime slurry conveying component is used to convey lime slurry to the flexible spraying pipe.

[0005] Preferably, the lime slurry conveying component includes a liquid storage barrel, a conveying pump, a first conveying pipe, a second conveying pipe, and a control switch.

DETAILED DESCRIPTION

[0020] The following will be combined with specific embodiments and attached Figures 1-5 , the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the preferred embodiments of the utility model, not all of the embodiments. Those skilled in the art can make similar modifications without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0021] The utility model provides a device for measuring the diameter of forest trees, painting lime, and counting positions, which includes a controller box 1, a controller, a mobile trolley, a lime slurry spraying system, a laser rangefinder 3, a GPS locator, and a radar ranging sensor. The controller can be a mature single-chip microcomputer or PLC controller available on the market. In this specific embodiment, to reduce the overall operating weight, a single-chip microcomputer is preferably selected as the controller. This controller also has a storage function to store the detection data of the laser rangefinder 3, the GPS locator, and the radar ranging sensor. The laser rangefinder 3, the GPS locator, and the radar ranging sensor are all mature technical products in the prior art, so the working principles of the laser rangefinder 3, the GPS locator, and the radar ranging sensor will not be introduced in detail here. The laser rangefinder 3 is mainly used to assist in the preliminary measurement of the diameter at a specific height of the tree trunk. The GPS locator is mainly used to measure the geographical location information of a single tree trunk. The radar ranging sensor is mainly used for monitoring the position at a specific height of the tree trunk. The lime slurry spraying system includes a lime slurry conveying component, a spraying operation frame, and a flexible spraying pipe 27. The spraying operation frame includes a hand-held handle 22, a semi-circular support seat 23, a left opening and closing arm 24, and a right opening and closing arm 25. The rear part of the hand-held handle 22 is fixedly connected to the front part of the semi-circular support seat 23. The diameter of the semi-circular support seat 23 can be determined according to the diameter range of the measured target tree trunk. During use, it is convenient for it to be able to surround the outside of the tree trunk 101. The left opening and closing arm 24 and the right opening and closing arm 25 are respectively hinged at the left rear end and the right rear end of the semi-circular support seat 23, and the left opening and closing arm 24 and the right opening and closing arm 25 are symmetrically arranged left and right. The left opening and closing arm 24 and the right opening and closing arm 25 are both arc-shaped. The left opening and closing arm 24 can automatically swing to the right and return to the initial position. The right opening and closing arm 25 can automatically swing to the left and return to the initial position. A surrounding entrance 28 is reserved between the rear ends of the left opening and closing arm 24 and the right opening and closing arm 25. In actual application, when the left opening and closing arm 24 and the right opening and closing arm 25 are both in the initial position, at this time, the semi-circular support seat 23, the left opening and closing arm 24, and the right opening and closing arm 25 form a ring-shaped frame with a surrounding entrance 28. After the left opening and closing arm 24 and the right opening and closing arm 25 are opened under the action of an external force, the ring-shaped frame formed by the semi-circular support seat 23, the left opening and closing arm 24, and the right opening and closing arm 25 can be smoothly sleeved outside the tree trunk 101. When pulling the hand-held handle 22 away from the tree trunk 101, the ring-shaped frame will be separated from the tree trunk 101. After being completely separated, the left opening and closing arm 24 and the right opening and closing arm 25 will automatically return to the initial position. To facilitate the left opening and closing arm 24 and the right opening and closing arm 25 to open under the action of an external force, here, a guide rod 26 is fixedly arranged at the rear end of each of the left opening and closing arm 24 and the right opening and closing arm 25. The two guide rods 26 are distributed in a V shape. When surrounding the tree trunk, the two guide rods 26 are aligned with the tree trunk, and then, the hand-held handle 22 is pushed in the direction close to the tree trunk 101.With the contact between the guide rod 26 and the outer side of the tree trunk 101, and with continuous pushing, under the guiding action of the guide rod 26, the left opening and closing arm 24 and the right opening and closing arm 25 are opened. When the tree trunk 101 completely enters the annular frame, the left opening and closing arm 24 and the right opening and closing arm 25 automatically return to the initial position, thereby realizing the encircling of the tree trunk 101. The controller box 1 is arranged on the hand-held handle 22. The controller, GPS locator and radar distance measuring sensor are all arranged in the controller box. As the hand-held handle 22 moves up and down, the radar distance measuring sensor can realize the real-time detection of the height of the hand-held handle 22 from the ground. The GPS locator realizes the statistics of the geographical location of the corresponding tree trunk. The laser rangefinder 3 is fixedly arranged at the rear right end of the semi-circular support base 23, and the laser beam axis of the laser rangefinder 3 coincides with the connection line 102 between the left end and the right end of the rear side of the semi-circular support base 23. The purpose of the laser beam axis of the laser rangefinder 3 coinciding with the connection line 102 between the left end and the right end of the rear side of the semi-circular support base 23 is that after the encircling process is completed, it is convenient to align the laser beam axis of the laser rangefinder 3 with the center of the tree trunk by operating the hand-held handle 22, so as to achieve the accuracy of tree trunk diameter measurement as much as possible. The controller is electrically connected to the GPS locator, radar distance measuring sensor and laser rangefinder 3. The controller can be used to control the operation of the GPS locator, radar distance measuring sensor and laser rangefinder 3. The flexible spraying pipe 27 is arranged below the annular frame with an opening formed by the semi-circular support base 23, left opening and closing arm 24 and right opening and closing arm 25. Because the flexible spraying pipe 27 has a certain flexibility, the part of the flexible spraying pipe 27 located below the left opening and closing arm 24 and the right opening and closing arm 25 can smoothly follow the opening and closing movement of the left opening and closing arm 24 and the right opening and closing arm 25. When the annular frame completes the encircling of the tree trunk, the flexible spraying pipe 27 synchronously realizes the encircling outside the tree trunk 101. Both ends of the flexible spraying pipe 27 are in a closed state. A number of nozzles 271 are arranged at equal intervals on the side wall of the flexible spraying pipe 27, and the liquid outlets of the nozzles 271 all point to the center of the semi-circular support base 23. After the flexible spraying pipe 27 completes the encircling of the tree trunk 101, when high-pressure lime slurry flows into the flexible spraying pipe 27, the lime slurry is sprayed out through the nozzles 271, thereby realizing the work of brushing lime on the tree trunk 101. During the continuous spraying process of the nozzles 271, the flexible spraying pipe 27 is moved up and down to realize the brushing lime operation within a certain height range of the tree trunk. During the process of the annular frame encircling or separating from the tree trunk 101, in order to prevent the nozzles 271 from colliding with the outer side wall of the tree trunk, the nozzles 271 can be located outside the lower part of the inner circle of the annular frame, that is, when the side wall of the tree trunk contacts the inner side wall of the annular frame, there is still a certain gap between the nozzles 271 and the side wall of the tree trunk, and then the anti-collision protection of the nozzles 271 can be effectively realized; The lime slurry conveying assembly is used to convey lime slurry to the flexible spraying pipe 27.,

[0022] On the basis of the above embodiments, the specific implementation manner of the lime slurry conveying assembly is as follows: The lime slurry conveying assembly includes a liquid storage barrel, a delivery pump, a first delivery pipe, a second delivery pipe 21, and a control switch. The liquid storage barrel and the delivery pump are both placed on the mobile trolley. The delivery pump is used to achieve high-pressure pumping of the lime solution. Lime slurry is contained in the liquid storage barrel. The inlet of the delivery pump is communicated with the inner bottom of the liquid storage barrel through the first delivery pipe. The outlet of the delivery pump is communicated with the flexible spraying pipe 27 through the second delivery pipe 21, and a part of the second delivery pipe 21 penetrates through the hand-held handle 22. The control switch is arranged at the front end of the hand-held handle 22, and the control switch is electrically connected to the controller. In practical applications, when lime slurry spraying operation is required, the control switch sends signals to the controller to turn on the delivery pump, the laser rangefinder 3, the GPS locator, and the radar rangefinder, so that the device synchronously performs lime brushing, diameter measurement, and geographical location information statistics work. According to the forest farm management requirements, generally, the diameter at a height of 1.2 meters from the ground of the tree trunk is measured. Therefore, in the actual working process, when the radar rangefinder detects that the height of the hand-held handle 22 is 1.2 meters at this time, it sends a data measurement and recording signal to the controller for the laser rangefinder 3, and then the measurement data of the tree trunk diameter at a height of 1.2 meters is recorded. After the data at this location is recorded, the controller uses this data as the basic data and according to the set calculation program, and finally realizes the diameter data of the tree trunk 101.

[0023] Based on the above embodiments, the specific implementation manner for the left opening and closing arm 24 and the right opening and closing arm 25 to automatically return to the initial position is as follows: A left torsion spring 4 is arranged on the hinge shaft 103 of the left opening and closing arm 24 and the semi-circular support seat 23. Specifically, a hinge groove 232 is arranged at the left end of the rear side of the semi-circular support seat 13, the hinge shaft 103 is fixedly arranged in the hinge groove 232, the left torsion spring 4 is sleeved on the hinge shaft 103, two hinge lugs 242 are arranged at the front end of the left opening and closing arm 24, the hinge lugs 242 are sleeved on the hinge shaft 103 and the left torsion spring 4 is clamped between the two hinge lugs 242. One of the two torsion bars at the outer end of the left torsion spring 4 abuts against the left side wall of the left opening and closing arm 24, and the other abuts against the left side wall of the semi-circular support seat 23. Through the above installation of the left torsion spring 4, it always exerts a thrust force on the left opening and closing arm 24 to swing to the right. During the process that the left opening and closing arm 24 rotates around the hinge shaft 103 under the push of the torsion spring, when the first limiting part 231 on the right side of the front part of the left opening and closing arm 24 abuts against the second limiting part 241 corresponding to the first limiting part 231 at the left end of the rear side of the semi-circular support seat 23, the left opening and closing arm 24 stops rotating, thereby realizing the positioning of the left opening and closing arm 24. At this time, the left opening and closing arm 24 is in the initial position. When an external force pushes the left opening and closing arm 24 to rotate to the left, the left torsion spring 4 is compressed. When the external force is removed, the left opening and closing arm 24 rotates under the push of the left torsion spring 4 and returns to the initial position. A right torsion spring is arranged on the hinge shaft of the right opening and closing arm 25 and the semi-circular support seat 23, and the right torsion spring always exerts a thrust force on the right opening and closing arm 25 to swing to the left. In this specific implementation, the specific setting manner of the right torsion spring at the right end of the rear side of the right opening and closing 25 and the semi-circular support seat 23 can completely refer to the specific setting manner of the left torsion spring 4. Therefore, the specific implementation manner of the right torsion spring will not be introduced in detail. During the actual application process, when the two guide rods 26 are pushed close to the tree trunk, due to the guiding effect of the guide rods 26, the left opening and closing arm 24 and the right opening and closing arm 25 are gradually opened. During the continuous opening process of the left opening and closing arm 24 and the right opening and closing arm 25, the left torsion spring 4 and the right torsion spring are compressed. When the tree trunk completely enters the annular frame, the external force that pushes the left opening and closing arm 24 and the right opening and closing arm 25 to open is removed. At this time, under the action of the left torsion spring 4 and the right torsion spring, the left opening and closing arm 24 and the right opening and closing arm 25 automatically rotate back to the initial position, and then the surrounding work is completed. After the lime brushing operation is completed, pulling the handheld handle 22 in the direction away from the tree trunk 101, the left opening and closing arm 24 and the right opening and closing arm 25 are pushed open by the tree trunk 101 again, so as to finally realize the separation of the tree trunk 2 in the annular frame. After the tree trunk is separated, the left opening and closing arm 24 and the right opening and closing arm 25 return to the initial working position again, which is convenient for the lime brushing operation of the next tree trunk 101.

[0024] On the basis of the above-mentioned embodiments, to facilitate the installation and fixation of the laser rangefinder 3, a first mounting seat 31 is fixedly arranged on the right end portion at the rear side of the semi-circular support seat 23, and the laser rangefinder 3 is arranged on the first mounting seat 31.

[0025] On the basis of the above-mentioned embodiments, to reduce the friction between the left opening and closing arm 24 and the right side wall of the semi-circular support seat 23 and the tree trunk, and at the same time, to improve the measurement data accuracy of the laser rangefinder 3 as much as possible, an arc-shaped plate 5 is arranged on the upper part of the left opening and closing arm 24 and the upper left part at the rear side of the semi-circular support seat 23. A set of surrounding guiding components 6 are arranged below the arc-shaped plate 5. The two sets of surrounding guiding components 6 are distributed in a front-back symmetrical state. Each set of surrounding guiding components 6 includes a ball bracket 61 and a ball 62. The ball bracket 61 is arranged below the arc-shaped plate 5. The ball 62 is clamped in the ball bracket 61 and the ball 62 can rotate freely relative to the ball bracket 61. Specifically, the ball bracket 61 is a hollow frame. A circular opening is arranged on one side wall of the hollow frame. The ball 62 is clamped in the hollow frame and part of the sphere is exposed outside the hollow frame through the circular opening. To prevent the ball 62 from slipping out of the circular opening and ensure the stable clamping of the ball 62 in the ball bracket 61, here, the left side wall of the ball 62 is attached to the right side wall inside the hollow frame. At the same time, the diameter of the circular opening is 4 mm smaller than the diameter R of the ball 62. Through the above setting method, it can be ensured that the ball 62 can rotate freely in all directions in the hollow frame. When performing the surrounding operation, the ball 62 contacts the side surface of the tree trunk. The rolling action of the ball 62 can reduce the wear of the left opening and closing arm 24 and the right side wall of the semi-circular support seat 23. At the same time, by using the rolling action of the ball 62, it is convenient for the device to move up and down flexibly relative to the tree trunk, and at the same time, it can also move back and forth flexibly. Since the two balls 62 distributed on the left opening and closing arm 24 and the semi-circular support seat 23 are distributed in a front-back symmetrical state and are distributed on the same circle, after the surrounding work is completed, it is convenient to realize the surrounding of the two balls 62 on the tree trunk. After the two balls 62 are tightly abutted against the tree trunk, it is convenient to align the laser beam of the laser rangefinder 3 with the center of the tree trunk, so as to realize the measurement accuracy of the tree trunk diameter as much as possible. The specific principle of using the laser rangefinder 3 to measure the tree trunk diameter is as follows: Figure 5 As shown in the figure, when the surrounding work is completed and the two balls 62 are tightly abutted against the side wall of the tree trunk, at this time, the laser rangefinder 3 is basically opposite to the center of the tree trunk. Since the distance L1 between the laser emission end face of the laser rangefinder 3 and the outer tangent circle of the right side walls of the two balls 62 is fixed, and at the same time, the outer side wall of the tree trunk coincides with the outer tangent circle, therefore, L1 can be used as the basic data for measuring the tree trunk diameter. When the laser rangefinder 3 obtains the distance L2 between its emission end face and the side wall of the tree trunk, then the diameter of the tree trunk 101 can be directly obtained by subtracting L2 from L1.

[0026] On the basis of the above embodiments, to facilitate the fixation of the ball bracket 61 on the arc-shaped plate 5, herein, an adjustment positioning hole 51 is provided on the arc-shaped plate 5, and the threaded rod 611 provided on the upper part of the ball bracket 61 is sleeved in the adjustment positioning hole 51. A locking nut 63 is sleeved on the threaded rod 611, and the ball bracket 61 is firmly fixed to the lower part of the arc-shaped plate 5 through the locking nut 63. Further, to facilitate the two balls 62 to reasonably and effectively surround tree trunks with different diameters, herein, the adjustment positioning hole 51 is an arc-shaped long round hole, and the threaded rod 611 can be adjusted in position within the adjustment positioning hole 51, so as to adjust the arc distance between the two balls 62. When the arc distance between the two balls 62 is small, it is convenient to effectively surround a tree trunk with a small diameter. When the arc distance between the two balls 62 is large, it is convenient to effectively surround a tree trunk with a large diameter.

[0027] After the annular frame surrounds the outside of the tree trunk, to make the annular frame and the tree trunk as perpendicular as possible, herein, a second mounting seat 233 is fixedly provided below the lower left end of the rear side of the semi-circular support seat 23, and a surrounding guiding assembly 6 is provided on the second mounting seat 233. In the left front projection or the right front projection, the three balls 62 are distributed in an isosceles triangle state. In practical applications, when force is applied to make all three balls 62 fit against the outer wall of the tree trunk, the adjustment of the horizontal placement posture of the annular frame is realized, and then it is beneficial to make the annular frame horizontally distributed relative to the tree trunk.

[0028] The process of using the present utility model for lime brushing, diameter measurement and geographical location statistics of tree trunks is as follows: Move the mobile trolley to a suitable position. Then, hold the handheld handle 22 by hand so that the two guide rods 26 are aligned with the tree trunk 101. After alignment, push the handheld handle 22 towards the tree trunk. During the movement of the handheld handle 22, utilize the guiding function of the guide rods 26 to realize the encirclement of the tree trunk by the semi-circular support seat 23, the left opening and closing arm 24 and the right opening and closing arm 25. After the encirclement is completed, make the three ball bearings 62 close to the side wall of the tree trunk, and make the encirclement height higher than 1.2 meters. Then, press the control switch. After the control switch is started, it sends a signal to the controller. After the controller receives the signal, start the delivery pump, the radar rangefinder, the GPS locator and the laser rangefinder 3. When slurry sprays out from the nozzle 271, the staff drives the annular frame to move down along the tree trunk through the handheld handle 22. After moving close to the ground, move up to near the initial position. Then, release the control switch. After the control switch is released, it sends a stop signal to the controller. After the controller receives the stop signal, stop the operation of the delivery pump, the radar rangefinder, the GPS locator and the laser rangefinder 3, thereby completing the lime brushing, diameter measurement and geographical location statistics of the tree trunk. During the reciprocating movement of the annular frame up and down, ensure that the three ball bearings 62 always fit as closely as possible to the side wall of the tree trunk. At the same time, during the reciprocating movement of the annular frame up and down, when the radar rangefinder detects that the distance from the ground is 1.2 meters, it sends a diameter measurement value recording signal to the controller. After the controller receives this signal, synchronously record the measurement data of the laser rangefinder 3 at this time, and use this measurement data as the basic data for subsequent calculation and storage of the tree trunk diameter. In practical applications, try to make the measurement initial end of the radar rangefinder and the height of the laser beam of the laser rangefinder 3 be in the same horizontal plane, so as to improve the accuracy of the diameter measurement data at the specified height.

[0029] In the present utility model, "front", "rear", "upper", "lower", "left" and "right" are all relative positions used for conveniently describing the positional relationship, so they cannot be understood as absolute positions to limit the protection scope.

[0030] Except for the technical features described in the specification, they are all known technologies to those skilled in the art.

[0031] As described above, the preferred embodiments and examples of the present utility model have been described in detail in conjunction with the drawings. However, the present utility model is not limited to the above embodiments and examples. For those of ordinary skill in the art in this technical field, without departing from the concept of the present utility model, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
