Description

Technical Field

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

[0002] Forestry planning is a comprehensive and systematic arrangement and deployment of forestry production, management, protection and other activities. It comprehensively considers multiple factors such as the status of forest resources, ecological and environmental needs, and social and economic development goals, and formulates scientific and reasonable forestry development strategies, goals and specific implementation plans. Forestry planning is crucial to the sustainable use of forest resources and the stability of the ecosystem.

[0003] In forestry planning, the protection of rare and endangered tree species is of vital importance. In order to create a good growth environment for rare tree species, it is often necessary to clear other trees within a certain range around them that may affect the production of rare tree species, and build fences to protect them. This requires staff to measure whether the distance between rare tree species and surrounding objects is within a reasonable range, and to draw lines at the specified distance for subsequent fence laying.

[0004] However, in the prior art, workers usually use a tape measure or a laser rangefinder to measure the distance between the rare tree species and other surrounding trees one by one, and make simple marks. After the distance measurement between the trees is completed, the distance between the fence and the rare tree species is confirmed. In this way, although the measurement can be completed, the measurement efficiency is low, and when the trees are subsequently cleared, if there are many trees around, the problem of missing felling may occur. In view of this, the present invention is specially proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and to provide a distance measuring device and a measuring method for forestry planning that can overcome the above problems or at least partially solve the above problems.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a distance measuring device for forestry planning, comprising: a clamping member, a telescopic measuring rod and a marking mechanism; the clamping member comprises two symmetrically distributed semicircular clamping plates, the positions where the two semicircular clamping plates are attached to each other are symmetrically fixedly connected with fixing ears, and every two adjacent fixing ears are fixedly connected by fixing bolts; the two semicircular clamping plates are each provided with a first T-shaped slide groove for matching use; a first T-shaped block is slidably connected to the first T shaped slide groove; the marking mechanism includes a mobile trolley, a storage box and a suction pump, the storage box is fixedly installed on the mobile trolley, the suction pump is fixedly installed on the mobile trolley, and the feed end is connected with the discharge end of the storage box; the spray pipe is fixedly installed on the mobile trolley through a support rod, and the feed end is connected with the discharge end of the suction pump, and the discharge port of the spray pipe is arranged facing downward; an articulated seat is installed on one side of the storage box, and the two ends of the telescopic measuring rod are respectively connected to the first T-block and the articulated seat.

[0007] In order to facilitate drawing a complete circle on the outside of the rare tree species so that the staff can lay the fence more accurately, further, the storage box is fixedly connected to a shell on one side close to the hinged seat, a second T-shaped slide groove is opened in the shell, a second T-shaped block is slidably connected in the second T-shaped slide groove, and the hinged seat is fixedly connected to the second T-shaped block.

[0008] In order to facilitate the replacement of telescopic measuring rods of different lengths according to needs, the telescopic measuring rod further includes a multi-section telescopic rod and a threaded head, the threaded head is fixedly connected to both ends of the multi-section telescopic rod, and the first T-block and the hinged seat are both provided with threaded holes for use with the threaded head.

[0009] In order to facilitate the removal of weeds at the marking position so that the marking is clearer, it further includes a drive motor and a weeding knife group. The drive motor is fixedly connected to the front end of the mobile cart, and the output end of the drive motor passes downward through the mobile cart and is fixedly connected to the weeding knife group.

[0010] In order to facilitate guiding the weeds to both sides so that the lime slurry can better penetrate into the soil to inhibit the growth of weeds, further, an arc-shaped baffle is fixedly connected to the bottom of the mobile vehicle to block the weeds cut by the weeding knife group and guide them to both sides.

[0011] In order to facilitate the clamping piece to be applicable to rare tree species of different diameters, further, the semicircular clamping plate is symmetrically connected with an adjusting screw through a thread, and one end of the adjusting screw located on the inner side of the semicircular clamping plate is rotatably connected to the clamping plate.

[0012] In order to improve the stability between the clamping piece and the trunk of the rare tree species, further, the first T-shaped slide groove is opened in the middle position of the semicircular clamping plate, and the adjusting screw is located on the upper and lower sides of the first T-shaped slide groove.

[0013] In order to avoid the need for staff to manually limit the clamping plate when moving the clamping plate, further, the semicircular clamping plate is symmetrically slidably connected to guide rods on both sides of the adjusting screw, and one end of the guide rod is fixedly connected to the clamping plate.

[0014] In order to prevent the clamping plate from causing damage to the trunk of the rare tree species, further, a protective cushion is provided on the side of the clamping plate away from the adjusting screw.

[0015] A distance measurement method for forestry planning mainly includes the following steps:

[0016] S1: First, slide the first T-shaped block into the first T-shaped slot of one of the semicircular pallets, then dock the two semicircular pallets on the trunk of the rare tree species, and fix the two semicircular pallets on the trunk of the rare tree species by fixing bolts;

[0017] S2: Then the staff moves the trolley to the side away from the rare tree species to fully open the telescopic measuring rod. Then, while pushing the trolley to move, the staff starts the suction pump to spray the lime slurry onto the ground through the spraying pipe to mark the periphery of the rare tree species.

[0018] S3: When the mobile trolley is blocked by trees, the staff can retract the telescopic measuring rod so that the mobile trolley can pass over the blocking trees. After passing over the trees, the telescopic measuring rod can be straightened again to continue marking.

[0019] S4: When the mobile car moves a circle, the marking operation is completed. Then the staff can determine which trees need to be removed and the specific location of the fence according to the marking trajectory.

[0020] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art: the present invention uses the clamping member, the telescopic measuring rod and the marking mechanism and other components in coordination, and at the same time, the distance between the rare tree species and the surrounding trees can be measured, and the distance between the fence to be laid and the rare tree species can also be measured together, which not only improves the efficiency of the staff in measuring the distance, but also makes it easier for the staff to understand which trees need to be removed more intuitively, and also facilitates the laying of the fence according to the drawn marks.

[0021] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0032] Example 1: Reference Figure 1-Figure 7A distance measuring device for forestry planning includes: a clamping member 1, a telescopic measuring rod 2 and a marking mechanism 3; the clamping member 1 includes two symmetrically distributed semicircular clamping plates 101, the positions of the two semicircular clamping plates 101 being symmetrically fixedly connected with fixing ears 102, and each two adjacent fixing ears 102 are fixedly connected by fixing bolts 103; the two semicircular clamping plates 101 are each provided with a first T-shaped slide groove 108 for matching use; a first T-shaped block 109 is slidably connected in the first T-shaped slide groove 108; the marking mechanism 3 includes a moving trolley 30 1. A material storage box 302 and a suction pump 307. The material storage box 302 is fixedly mounted on the mobile trolley 301, and the suction pump 307 is fixedly mounted on the mobile trolley 301, and the feed end is connected with the discharge end of the material storage box 302; a material spraying pipe 308 is fixedly mounted on the mobile trolley 301 through a support rod, and the feed end is connected with the discharge end of the suction pump 307, and the discharge port of the material spraying pipe 308 is arranged facing downward; an articulated seat 306 is installed on one side of the material storage box 302, and both ends of the telescopic measuring rod 2 are respectively connected with the first T-block 109 and the articulated seat 306.

[0033] In the process of forestry planning, when encountering rare and endangered tree species that need special protection, forestry workers need to clear trees within a certain range that may affect the rare tree species and lay a circle of fences at a prescribed distance to protect them.

[0034] When it is necessary to measure whether the distance between the surrounding trees and the rare tree species is within a reasonable range, and to draw lines according to the specified distance for subsequent fence laying, the staff can transport the distance measuring device to the rare tree species, and then slide the first T-block 109 into the first T-shaped slide groove 108 of one of the semicircular pallets 101, and then dock the two semicircular pallets 101 on the trunk of the rare tree species, and adjust the height of the two semicircular pallets 101 so that the telescopic measuring rod 2 is in a horizontal position as much as possible. After adjustment, the two semicircular pallets 101 can be connected by the fixing bolts 103 to fix the two semicircular pallets 101 on the rare tree species.

[0035] After completing the connection between the distance measuring device and the rare tree species, the staff can move the mobile cart 301 to the side away from the rare tree species to fully open the telescopic measuring rod 2. Then the staff can transport full lime slurry into the storage box 302, and start the suction pump 307 to spray the lime slurry onto the ground through the spray pipe 308. When the spray pipe 308 sprays the lime slurry, the staff can push the mobile cart 301 to move in a circle around the rare tree species, so that a circle of marks can be drawn on the periphery of the rare tree species according to the specified distance, so that subsequent staff can lay the fence according to the marked line.

[0036] During the process of the spraying tube 308 spraying lime slurry in a circle around rare tree species, when the telescopic measuring rod 2 and the mobile cart 301 are blocked by trees, the staff can move the mobile cart 301 to one side of the clamping member 1 and retract the telescopic measuring rod 2 so that it can pass over the blocking trees. After passing over the trees, the telescopic measuring rod 2 can be straightened again to continue marking. When the mobile cart 301 moves one circle, the marking operation is completed.

[0037] It should be noted that, after the telescopic measuring rod 2 is fully extended, the distance between the mobile trolley 301 and the clamping member 1 is the distance between the fence and the rare tree species, and when the mobile trolley 301 and the telescopic measuring rod 2 rotate around the rare tree species, all trees whose distance to the rare tree species is less than the distance between the mobile trolley 301 and the clamping member 1 are trees that may affect the growth of the rare tree species. Therefore, when marking, the distance between other trees and the rare tree species can be indirectly measured, such as Figure 7 As shown, all the trees in the marked grooves are close to the rare tree species and will affect the growth of the rare tree species. In this way, the staff can more intuitively know which trees will affect the rare tree species and need to be removed. The staff no longer need to use a tape measure or rangefinder to measure the surrounding trees one by one, which effectively improves the efficiency of the staff in protecting rare tree species.

[0038] Example 2: Reference Figure 1-Figure 7 , a distance measuring device for forestry planning, is basically the same as Example 1, and further, a shell 303 is fixedly connected to one side of the storage box 302 close to the hinged seat 306, a second T-shaped slide groove 304 is opened in the shell 303, a second T-shaped block 305 is slidably connected in the second T-shaped slide groove 304, and the hinged seat 306 is fixedly connected to the second T-shaped block 305.

[0039] When the mobile trolley 301 is pushed to measure and mark a certain distance around the rare tree species, when the telescopic measuring rod 2 touches the tree to be cut down in the area, the housing 303, the second T-block 305 and the hinge seat 306 can be used to make the mobile trolley 301 continue to move forward for a distance, and when the telescopic measuring rod 2 passes over the tree to be cut down, the mobile trolley 301 can be moved backward for a distance, so as to measure the tree to be cut down. Figure 7 The groove opening shown is blocked so that the marking mechanism 3 can completely draw a circle, so that the subsequent staff can lay the fence more accurately along the drawn line.

[0040] Example 3: Reference Figure 1-Figure 7, a distance measuring device for forestry planning, is basically the same as Example 2, and further, the telescopic measuring rod 2 includes a multi-section telescopic rod 201 and a threaded head 202, the threaded head 202 is fixedly connected to both ends of the multi-section telescopic rod 201, and the first T-block 109 and the hinge seat 306 are both provided with threaded holes for use with the threaded head 202.

[0041] By making the multi-section telescopic rod 201 detachably connected to the first T-block 109 and the hinged seat 306 through the threaded head 202, when not in use, it is not only convenient for the staff to disassemble and store the device to reduce the occupied space, but when in use, the telescopic measuring rod 2 can also be replaced with the corresponding length according to the size of the required marking area, effectively improving the flexibility of the device when in use.

[0042] Example 4: Reference Figure 1-Figure 7 A distance measuring device for forestry planning is basically the same as Example 3, and further includes a driving motor 309 and a weeding knife group 3010. The driving motor 309 is fixedly connected to the front end of the moving cart 301, and the output end of the driving motor 309 passes downward through the moving cart 301 and is fixedly connected to the weeding knife group 3010.

[0043] An arc-shaped baffle plate 3011 is fixedly connected to the bottom of the mobile trolley 301 to block the weeds cut by the weeding knife group 3010 and guide them to both sides.

[0044] When the staff pushes the mobile cart 301 to move by the handle provided on the storage box 302, the driving motor 309 can be started, and the driving motor 309 will control the weeding knife group 3010 to rotate quickly, so that the weeds on the walking track of the mobile cart 301 can be removed to avoid the clarity of the lime slurry sprayed out by the spray pipe 308 for marking due to the high weeds, so that the staff can more conveniently cut down other trees in the range and lay fences later.

[0045] When the staff pushes the mobile cart 301 to remove weeds through the weeding knife group 3010, the arc-shaped baffle plate 3011 can block and guide the cut weeds, so as to facilitate blocking and guiding the cut weeds to both sides of the marked area, which can not only make the lime slurry better penetrate into the soil and inhibit the growth of weeds, but also prevent the cut weeds from splashing back onto the staff, and at the same time ensure that the marked lines are clearer.

[0046] Example 5: Reference Figure 1-Figure 7, a distance measuring device for forestry planning, which is basically the same as Example 4, and further, an adjusting screw 104 is symmetrically connected to the semicircular clamping plate 101 through a thread, and one end of the adjusting screw 104 located on the inner side of the semicircular clamping plate 101 is rotatably connected to a clamping plate 106. Through the arrangement of the adjusting screw 104 and the clamping plate 106, after the two semicircular clamping plates 101 are sleeved on the tree trunk through the fixing bolt 103, the adjusting screw 104 can be rotated, and then the clamping plate 106 can be moved toward the trunk until the clamping plate 106 is tightly attached to the surface of the trunk, which not only ensures the stability of the clamping member 1 installed on the tree trunk, but also makes the clamping member 1 suitable for trees of different thicknesses, effectively improving the applicability of the device.

[0047] The first T-shaped slide groove 108 is provided in the middle of the semicircular clamping plate 101, and the adjusting screw 104 is located at the upper and lower sides of the first T-shaped slide groove 108. Figure 3 As shown, by setting the first T-shaped slide groove 108 in the middle position and setting the adjusting screw 104 on the upper and lower sides of the semicircular clamping plate 101, when the marking mechanism 3 is controlled by the telescopic measuring rod 2 to move in a circle along the tree, the stability of the semicircular clamping plate 101 fixed on the tree trunk can be ensured, avoiding the semicircular clamping plate 101 from shaking, causing damage to the tree, and affecting the accuracy of measurement and marking.

[0048] The semicircular clamping plate 101 is symmetrically slidably connected to the guide rod 105 on both sides of the adjusting screw 104, and one end of the guide rod 105 is fixedly connected to the clamping plate 106. Through the setting of the guide rod 105, the clamping plate 106 can be limited and guided to prevent the clamping plate 106 from rotating when the adjusting screw 104 controls the movement of the clamping plate 106, so that when clamping the tree, the staff is required to manually limit the clamping plate 106, thereby facilitating the staff to quickly fix the clamping member 1 on the tree trunk.

[0049] A protective cushion 107 is provided on one side of the clamping plate 106 away from the adjusting screw 104. Through the provision of the protective cushion 107, when the clamping plate 106 is in close contact with the tree trunk, the tree trunk can be protected to avoid damage to rare tree species.
