A distance measuring device for forestry planning

Abstract

The invention discloses a distance measuring device for forestry planning, which belongs to the technical field of forestry measurement. The device comprises an adjustment unit and a measurement unit. By judging the deformation state of a plate body, information on soil properties and structural changes can be obtained. Since the lower end surface of the plate body is in contact with the upper end surface of the soil to be measured at this time, the expanded soil is turned over with the outer end surface of the plate body as a fulcrum, so that the structure and layer of the soil can be better observed and analyzed. The installation plate under the impact state returns to the quasi-working state, and the elastic potential energy accumulated by the spring itself is released, so that the knocking tube collides with the inner cavity wall of the box body at both ends. An early warning sound is emitted at the moment when the two contact, and construction personnel can hear the early warning sound within the vicinity of the device. The push rod and the push-out cross frame plate penetrate the inner cavity through the extended port, so that the push rod pushes the soil to be measured to a distance, and the device can switch between the quasi-working state and the flipping state.

Description

Technical Field

[0001] The invention relates to the technical field of forestry measurement, and in particular to a distance measuring device for forestry planning. Background Art

[0002] In forestry planning, distance measurement is an important technique used to assess the size, shape and distances between locations in a forest, especially the distances and layer structures of soils within the planning area.

[0003] In order to plan the layout of forestry seedling planting, forestry surveying and mapping personnel need to measure the planting distance between trees and the soil state and layer structure within a certain radius. The distance measuring devices currently available on the market can only perform ground measurements using tools such as rangefinders, measuring tapes, and total stations. It is impossible to measure the soil structure and layer within the radius around the plants in the forest and collect and centrally test the soil. Therefore, a distance measuring device for forestry planning is proposed. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings in the prior art and to propose a distance measuring device for forestry planning.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A distance measuring device for forestry planning comprises an adjustment unit and a measuring unit, wherein the side end face of the adjustment unit is connected to the measuring unit, and the measuring unit comprises a measuring box and a blocking plate installed in the inner cavity of the measuring box, the side end face of the blocking plate is arranged with an arrangement cross block, both sides of the inner cavity wall of the measuring box are provided with a limiting mechanism, and a protruding mechanism is interspersed between two groups of the limiting mechanisms, an adjustment frame plate is arranged at an edge position of one end of the measuring box away from the adjustment unit, and the second supporting mechanism is capable of rotational adjustment like the first supporting mechanism, and one end of the second supporting mechanism can support the entire adjustment frame plate in a deformed state, thereby improving the stability of the adjustment frame plate in a deformed state and ensuring the accuracy of the measurement result, and the blocking plate and the arrangement cross block block the soil wrapped between the devices, thereby reducing soil dust and pollution around the device, providing a cleaner and safer operating environment, and helping to maintain the originality of the soil and avoid interference with the soil by external factors, so as to obtain more accurate soil information and data.

[0007] Preferably, the limiting mechanism includes a knocking tube and a mounting plate installed on one end of the knocking tube, springs are arranged on both sides of the side end edge of the mounting plate, the edge position of the mounting plate is connected to the matching frame through a transversely arranged spring, and insertion holes are arranged transversely on the inner end surface of the mounting plate on one side.

[0008] Preferably, the limiting mechanism also includes an extended horizontal plate arranged at the edge of the matching frame on one side, a matching extension frame is opened in the middle of the matching frame on the other side, and an insertion support rod is arranged on the inner end surface of the other group of mounting plates, and the insertion support rod can be inserted into the inner cavity of the insertion hole, and the extended horizontal plate and the matching extension frame are adapted to each other. When the entire device is transported, the extension mechanism in the device is taken out, and the extended horizontal plate is inserted into the inner cavity of the matching extension frame, so that the two groups of limiting mechanisms form a whole in the transport state, ensuring that the various components of the device remain in an integral state during the transport process, reducing the risk of looseness and damage of the components.

[0009] Preferably, the matching frame and one end of the extended horizontal plate are fixedly mounted on the inner cavity wall of the measuring box, and the four groups of springs are all mounted on the inner cavity wall of the measuring box. When the driving motor is driven in reverse, the pushing horizontal frame plate and the pushing rod in the pushing state are retracted inwardly into the inner cavity of the extension port, and due to the open state of the pushing horizontal frame plate, a certain amount of soil can be brought into the inner cavity of the device. In the process of returning to the initial state, the extended positions of both ends of the pushing horizontal frame plate will be blocked by the mounting plate, and the soil will remain in the inner cavity of the box body. After measuring the soil at the same position for multiple times, the staff can collect and test the soil remaining in the inner cavity of the box body.

[0010] Preferably, the measuring box comprises a box body and observation holes opened on both sides of the edge of the box body, and a protruding opening is opened at the middle position of the end points of the box body.

[0011] Preferably, the extending mechanism includes a pushing cross cylinder and a pushing rod inserted and arranged at one end of the pushing cross cylinder, and push-out cross frame plates are arranged on both sides of the edge of one end of the pushing rod, and the opening width of the push-out cross frame plates is not greater than the width of the extending opening. In the quasi-working state, the two sets of mounting plates are flipped to a vertical state with the insertion hole as a fulcrum to the matching frame, and the mounting plates in the flipped state are pulled and involved by the spring. When the two sets of mounting plates are in the flipped state, the side end surfaces of the mounting plates are in contact with the top position of the pushing rod. When the driving motor externally connected to the other end of the pushing cross cylinder pushes the pushing rod toward the other end, the pushing rod and the push-out cross frame plate laterally impact the side end surfaces of the mounting plates, and the mounting plates in the impacted state return to the quasi-working state, and release the elastic potential energy accumulated by the spring itself, so that the knocking cylinder collides with the inner cavity wall of the box body at both ends, and a warning sound is issued at the moment the two contact, and the construction personnel can hear the warning sound within the vicinity of the device to remind nearby construction personnel to pay attention to safety. This helps prevent accidents. The push rod and the push-out cross frame plate pass through the inner cavity of the extension port, so that the push rod pushes the measured soil to a distance. The device can switch between a quasi-working state and a flipping state, so that the measured soil has more flexibility and controllability when measuring and operating.

[0012] Preferably, the adjustment frame plate includes a plate body and an inner limiting frame arranged transversely and installed in the inner cavity of the plate body. The overall device is inserted into the starting point of the soil to be measured with the outer surface of the first mounting cylinder as the support point. The rotating shaft, telescopic rod and inner supporting frame can rotate with the middle position of the supporting cylinder as the fulcrum, so that the positions of the rotation and support points can change freely. In this way, the arrangement and use of the device can be flexibly adjusted according to specific needs to adapt to different geological and soil conditions. When the first supporting mechanism is in a rotating state, the inner supporting frame supports the inner end surface of the plate body in a bent state from the inside to the outside, and the inner supporting frame supports each group of inner limiting frames at different positions from the inside to the outside. When the inner supporting frame contacts the inner limiting frames at both ends, the protruding curvature of the plate body is relatively gentle. When the inner supporting frame contacts the inner limiting frame in the middle, the protruding curvature of the plate body is in the most protruding state. The protruding state of the plate body is used to measure the protruding radius length between the plate body and the midpoint of the first mounting tube to measure and judge the soil. By judging the deformation state, information about soil properties and structural changes can be obtained. Because the lower end surface of the plate body is in contact with the upper end surface of the measured soil at this time, the expanded soil is turned over with the outer end surface of the plate body as a fulcrum, so that the structure and layer of the soil can be better observed and analyzed.

[0013] Preferably, the adjustment unit includes a bearing mechanism and a first supporting mechanism installed on the side end surface of the bearing mechanism, a second supporting mechanism is arranged on one side of the first supporting mechanism, the bearing mechanism includes a first mounting tube and an insertion hole opened on the side end surface of the first mounting tube, a second mounting tube is installed on the other end of the first mounting tube, the other end of the second mounting tube is connected to the reinforcement block through a connecting rod, an assembly block is laterally arranged on the outer end surface of the second mounting tube, and the assembly block and the reinforcement block are bent and connected through a series bending axis.

[0014] Preferably, the first supporting mechanism includes a supporting tube and a rotating shaft movably connected to the inner cavity of the supporting tube, the other end of the rotating shaft is connected to the inner supporting frame through a telescopic rod, and an inner fitting rod is arranged at the interval between the supporting tube and the series bending shaft, and the end point position of the inner fitting rod is fitted to the outer end surface of the series bending shaft.

[0015] Preferably, the diameter of the outer end surface of the inner receiving frame is consistent with the diameter of the groove of the inner limiting frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The soil is measured and judged by measuring the protruding radius length between the plate and the midpoint of the first mounting tube by utilizing the protruding state of the plate. Information on soil properties and structural changes can be obtained by judging the deformation state. Because the lower end surface of the plate is in contact with the upper end surface of the measured soil at this time, the expanded soil is turned over with the outer end surface of the plate as a fulcrum, so that the structure and layers of the soil can be better observed and analyzed.

[0018] The second supporting mechanism can be rotatably adjusted like the first supporting mechanism, and one end of the second supporting mechanism can support the entire adjustment frame plate in a deformed state, thereby improving the stability of the adjustment frame plate in a deformed state and ensuring the accuracy of the measurement results.

[0019] The set blocking plates and arranged horizontal blocks will block the soil wrapped between the devices, which can reduce soil dust and pollution around the devices, provide a cleaner and safer operating environment, help maintain the originality of the soil and avoid interference with the soil by external factors, so as to obtain more accurate soil information and data.

[0020] The installation plate under impact returns to the quasi-working state, and releases the elastic potential energy accumulated by the spring itself, so that the striking tube hits the inner cavity wall of the box body at both ends. The moment the two come into contact, an early warning sound is emitted, and construction workers in the vicinity of the device can hear the early warning sound to remind nearby construction workers to pay attention to safety. This helps prevent accidents. The push rod and the push-out cross frame plate pass through the inner cavity of the extension port, so that the push rod pushes the measured soil to a distance. The device can switch between the quasi-working state and the flip state, making the measurement and operation of the measured soil more flexible and controllable.

[0021] When the horizontal frame is pushed out and returns to its initial state, its two ends will be blocked by the mounting plates, and soil will remain in the inner cavity of the box. After measuring the soil at the same position several times, the staff can collect and test the soil remaining in the inner cavity of the box.

[0022] When the entire device is being transported, the extension mechanism in the device is taken out, and the extended horizontal plate is inserted into the inner cavity of the matching extension frame, so that the two sets of restriction mechanisms form a whole in the transport state, ensuring that the various components of the device remain in an integral state during the transport process, reducing the risk of loosening and damage of the components.

[0035] The limiting mechanism 24 includes a knocking tube 241 and a mounting plate 242 installed at one end of the knocking tube 241. Springs 243 are arranged on both sides of the side end edge of the mounting plate 242. The edge position of the mounting plate 242 is connected to the matching frame 245 through the transversely arranged springs 243. Insertion holes 244 are arranged transversely on the inner end surface of the mounting plate 242 on one side.

[0036] In Example 2, the limiting mechanism 24 also includes an extended horizontal plate 246 arranged at the edge of the matching frame 245 on one side, and a matching extension frame 247 is opened in the middle of the matching frame 245 on the other side. The inner end surfaces of another group of mounting plates 242 are arranged with insertion support rods 248, and the insertion support rods 248 can be inserted into the inner cavity of the insertion hole 244. The extended horizontal plate 246 and the matching extension frame 247 are adapted to each other. When the entire device is transported, the extending mechanism 25 in the device is taken out, and the extended horizontal plate 246 is inserted into the inner cavity of the matching extension frame 247, so that the two groups of limiting mechanisms 24 form a whole in the transport state, ensuring that the various components of the device remain in an integrated state during the transport process, reducing the risk of looseness and damage of the components.

[0037] Embodiment 3, the matching frame 245 and one end of the extended horizontal plate 246 are fixedly installed on the inner cavity wall of the measuring box 21, and the four groups of springs 243 are all installed on the inner cavity wall of the measuring box 21. When the driving motor is driven in the reverse direction, the ejection horizontal frame plate 253 and the push rod 252 in the ejection state retract inwardly into the inner cavity of the extension port 213, and because the ejection horizontal frame plate 253 is in the open state, a certain amount of soil can be brought into the inner cavity of the device. When the ejection horizontal frame plate 253 returns to the initial state, its two ends of the extended position will be blocked by the mounting plate 242, and the soil will remain in the inner cavity of the box body 211. After measuring the soil at the same position for multiple times, the staff can collect and detect the soil remaining in the inner cavity of the box body 211.

[0038] Embodiment 4, the measuring box 21 includes a box body 211 and observation holes 212 opened on both sides of the edge of the box body 211, and a protruding opening 213 is opened at the middle position of the end point of the box body 211. The protruding mechanism 25 includes a pushing horizontal cylinder 251 and a pushing rod 252 inserted and arranged at one end of the pushing horizontal cylinder 251. Both sides of the edge of one end of the pushing rod 252 are provided with a pushing horizontal frame plate 253, and the opening width of the pushing horizontal frame plate 253 is not greater than the width of the protruding opening 213. The two sets of mounting plates 242 in the quasi-working state are flipped to a vertical state with the matching frame 245 with the insertion hole 244 as the fulcrum. The mounting plates 242 in the flipped state are pulled and involved by the spring 243. When the two When the mounting plate 242 is in the flipping state, the side end surface of the mounting plate 242 contacts the top position of the push rod 252. When the driving motor externally connected to the other end of the push cross cylinder 251 pushes the push rod 252 to the other end, the push rod 252 and the push cross frame plate 253 impact the side end surface of the mounting plate 242 laterally. The mounting plate 242 in the impacted state returns to the quasi-working state, and releases the elastic potential energy accumulated by the spring 243 itself, so that the knocking cylinder 241 impacts the inner cavity wall of the box body 211 at both ends. The moment the two contact, an early warning sound is issued, and the construction personnel in the vicinity of the device can hear the early warning sound to remind the nearby construction personnel to pay attention to safety. This helps to prevent accidents. The push rod 252 and the push cross frame plate 253 penetrate the inner cavity of the extension port 213, so that the push rod 252 pushes the measured soil to a distance. The device can switch between the quasi-working state and the flipping state, so that the measured soil has more flexibility and controllability when measuring and operating.

[0039] Embodiment 5, the adjustment frame plate 26 includes a plate body 261 and an inner limiting frame 262 which is arranged horizontally and installed in the inner cavity of the plate body 261. The whole device is inserted into the starting point of the soil to be measured with the outer surface of the first mounting cylinder 111 as the support point. The rotating shaft 122, the telescopic rod 123 and the inner supporting frame 124 can rotate with the middle position of the supporting cylinder 121 as the fulcrum, so that the position of the rotation and support points can be changed freely. In this way, the arrangement and use of the device can be flexibly adjusted according to specific needs to adapt to different geological and soil conditions. When the first supporting mechanism 12 is in a rotating state, the inner receiving frame 124 supports the inner end surface of the plate body 261 in a bent state from the inside to the outside, and the inner receiving frame 124 supports each group of inner limiting frames 262 at different positions from the inside to the outside. When the inner receiving frame 124 contacts the inner limiting frames 262 at both ends, the protruding curvature of the plate body 261 is relatively gentle. When the inner receiving frame 124 contacts the inner limiting frame 262 in the middle, the protruding curvature of the plate body 261 is in the most protruding state. The protruding state of the plate body 261 is used to measure the protruding radius length between the plate body 261 and the midpoint of the first mounting tube 111 to measure and judge the soil. By judging the deformation state, information about soil properties and structural changes can be obtained. Because the lower end surface of the plate body 261 is in contact with the upper end surface of the measured soil at this time, the expanded soil is turned over with the outer end surface of the plate body 261 as the fulcrum, so that the structure and layer of the soil can be better observed and analyzed.

[0040] Embodiment 6, the adjustment unit 1 includes a bearing mechanism 11 and a first supporting mechanism 12 installed on the side end surface of the bearing mechanism 11, a second supporting mechanism 13 is arranged on one side of the first supporting mechanism 12, the bearing mechanism 11 includes a first mounting tube 111 and an insertion hole 112 opened on the side end surface of the first mounting tube 111, a second mounting tube 113 is installed on the other end of the first mounting tube 111, the other end of the second mounting tube 113 is connected to a reinforcing block 115 through a connecting rod 114, an assembly block 116 is transversely arranged on the outer end surface of the second mounting tube 113, and the assembly block 116 is bent and connected with the reinforcing block 115 through a series bending shaft 117;

[0041] The first supporting mechanism 12 includes a supporting tube 121 and a rotating shaft 122 movably connected to the inner cavity of the supporting tube 121. The other end of the rotating shaft 122 is connected to the inner supporting frame 124 through a telescopic rod 123. An inner fitting rod 125 is arranged at the interval between the supporting tube 121 and the series bending shaft 117. The end point position of the inner fitting rod 125 fits the outer end surface of the series bending shaft 117. The diameter of the outer end surface of the inner supporting frame 124 is consistent with the diameter of the groove of the inner limiting frame 262.

[0042] In summary: a distance measuring device for forestry planning, comprising an adjustment unit 1 and a measuring unit 2, the side end face of the adjustment unit 1 is connected to the measuring unit 2, the measuring unit 2 comprises a measuring box 21 and a blocking plate 22 installed in the inner cavity of the measuring box 21, the side end face of the blocking plate 22 is arranged with an arrangement cross block 23, both sides of the inner cavity wall of the measuring box 21 are provided with a limiting mechanism 24, and a protruding mechanism 25 is interspersed between the two groups of limiting mechanisms 24, an adjustment frame plate 26 is arranged at the edge position of one end of the measuring box 21 away from the adjustment unit 1, the overall device is inserted into the starting point of the soil to be measured with the outer surface of the first mounting cylinder 111 as the support point, and the rotating shaft 122, the telescopic rod 123 and the inner receiving frame 124 can be rotated with the middle position of the support cylinder 121 as the fulcrum, so that the position of the rotation and support points can be changed freely. In this way, the arrangement and use of the device can be flexibly adjusted according to specific needs to adapt to different geological and soil conditions. When the first supporting mechanism 12 is in a rotating state, the inner receiving frame 124 supports the inner end surface of the plate body 261 in a bent state from the inside to the outside, and the inner receiving frame 124 supports each group of inner limiting frames 262 at different positions from the inside to the outside. When the inner receiving frame 124 contacts the inner limiting frames 262 at both ends, the protruding curvature of the plate body 261 is relatively gentle. When the inner receiving frame 124 contacts the inner limiting frame 262 in the middle, the protruding curvature of the plate body 261 is in the most protruding state. The protruding state of the plate body 261 is used to measure the protruding radius length between the plate body 261 and the midpoint of the first mounting tube 111 to measure and judge the soil. By judging the deformation state, information about soil properties and structural changes can be obtained. Because the lower end surface of the plate body 261 is in contact with the upper end surface of the measured soil at this time, the expanded soil is turned over with the outer end surface of the plate body 261 as a fulcrum, so that the structure and layer of the soil can be better observed and analyzed.

[0043] The second supporting mechanism 13 is capable of rotational adjustment like the first supporting mechanism 12, and one end of the second supporting mechanism 13 can support the entire adjustment frame plate 26 in a deformed state, thereby improving the stability of the adjustment frame plate 26 in a deformed state and ensuring the accuracy of the measurement result;

[0044] The blocking plate 22 and the arranged horizontal blocks 23 block the soil between the devices, which can reduce dust and pollution of the soil around the devices, provide a cleaner and safer operating environment, help maintain the original nature of the soil and avoid interference with the soil by external factors, so as to obtain more accurate soil information and data;

[0045] The two groups of mounting plates 242 in the quasi-working state are flipped to a vertical state with the matching frame 245 with the insertion hole 244 as the fulcrum. The mounting plates 242 in the flipped state are pulled and involved by the spring 243. When the two groups of mounting plates 242 are in the flipped state, the side end surfaces of the mounting plates 242 contact the top position of the push rod 252. When the driving motor externally connected to the other end of the push cross cylinder 251 pushes the push rod 252 toward the other end, the push rod 252 and the push cross frame plate 253 laterally impact the side end surfaces of the mounting plates 242. The mounting plates 242 in the impacted state return to the quasi-working state, and release the elastic potential energy accumulated by the spring 243 itself, so that the knocking cylinder 241 collides with the inner cavity wall of the box body 211 at both ends. An early warning sound is emitted at the moment the two contact, and the construction personnel in the vicinity of the device can hear the early warning sound to remind the nearby construction personnel to pay attention to safety. This helps prevent accidents. The push rod 252 and the push-out cross frame plate 253 penetrate through the inner cavity of the extension port 213, so that the push rod 252 pushes the measured soil to a distance. The device can be switched between a quasi-working state and a flipping state, so that the measurement and operation of the measured soil are more flexible and controllable.

[0046] When the driving motor is driven in the reverse direction, the push-out horizontal frame plate 253 and the push rod 252 in the push-out state are retracted inwardly into the inner cavity of the extension port 213, and because the push-out horizontal frame plate 253 is in the open state, a certain amount of soil can be brought into the inner cavity of the device. When the push-out horizontal frame plate 253 returns to the initial state, the extended positions at both ends thereof will be blocked by the mounting plate 242, and the soil will remain in the inner cavity of the box body 211. After measuring the soil at the same position for multiple times, the staff can collect and test the soil remaining in the inner cavity of the box body 211 in a centralized manner;

[0047] When the entire device is being transported, the extending mechanism 25 in the device is taken out, and the extended horizontal plate 246 is inserted into the inner cavity of the matching extension frame 247, so that the two sets of limiting mechanisms 24 form a whole in the transport state, ensuring that the various components of the device remain in an integral state during the transport process, reducing the risk of loosening and damage of the components.
