Description

Technical Field

[0001] The present invention relates to the technical field of laser measurement, and specifically to a laser measurement device for processing redwood boards. Background Art

[0002] Redwood boards refer to boards processed from specific redwood tree species that meet the definition of the "National Standard for Redwood in China" (GB / T 18107). Their materials must be strictly limited to the scope of 5 genera, 8 categories, and 29 species of redwoods defined by the national standard, such as precious tree species like Pterocarpus santalinus and Dalbergia odorifera. These woods have dense textures, excellent stability, corrosion resistance, and insect resistance, and can withstand fine carving and long-term use without being easily deformed or cracked. In the wood processing industry, the core uses of redwood boards are concentrated in the high-end manufacturing field. Their natural textures and deep colors endow furniture with unique artistic value, while their high-density materials ensure the stability of load-bearing structures. Their durability and cultural symbolic significance make them become space decoration elements that demonstrate identity. In addition, redwood boards also occupy an irreplaceable position in niche fields such as musical instrument making and cultural relic inlay.

[0003] Due to their scarcity, cultural value, and excellent performance, redwood boards need to be accurately screened through multi-dimensional technical means at the stage of selecting raw logs for processing to balance quality, cost, and compliance. Traditional selection relied on the experience of craftsmen, but modern technology has gradually formed a composite system of "scientific identification + intelligent analysis". For example, in the selection of redwoods, laser measuring instruments can quickly obtain data such as the diameter, length, and curvature of raw logs through high-precision, non-contact scanning technology, providing a basis for subsequent cutting plans; through high-resolution laser point cloud modeling, surface defects such as cracks, knots, and wormholes can be accurately located, and combined with AI image analysis algorithms, the defective areas can be automatically marked, and the texture direction and local density changes of the wood surface can be analyzed, significantly improving the efficiency and accuracy of raw log screening.

[0004] When selecting redwoods, after the staff carry the laser measurement equipment into the raw log forest farm, although the collection efficiency is outstanding, due to the heavy weight of the laser measurement equipment itself, and the complex geological conditions and high-density coverage of the forest farm site environment, it is difficult for the staff to relieve the action burden by means of transportation. The staff carrying the laser measurement equipment are extremely prone to increased fatigue and discomfort due to excessive burden during the work process, resulting in the staff having to rest frequently during the redwood selection process. If the redwood selection work is carried out in summer when the outdoor temperature is relatively high, the action burden will be further aggravated, which is even more unfavorable for the redwood selection work.

[0005] In view of this, in order to overcome the above technical problems, the present invention proposes a laser measurement device for processing redwood boards. Summary of the Invention

[0006] To make up for the deficiencies of the prior art, the technical solution adopted by the present invention to solve its technical problems is as follows: A laser measurement device for processing redwood boards according to the present invention includes:

[0007] A measuring instrument housing, in which a measuring instrument main body is installed;

[0008] A radar bracket, which is also installed on the back main body, and a lidar is installed on the radar bracket;

[0009] Shoulder straps, which are symmetrically and fixedly connected to the measuring instrument housing, and are used for staff to carry the measuring instrument housing on the back;

[0010] It also includes:

[0011] A back-carrying sandwich layer, which is fixedly connected between the measuring instrument housing and the shoulder straps. The back-carrying sandwich layer includes:

[0012] A back-attaching layer, which is close to the back of the staff;

[0013] A support layer, which is attached to the end face of the measuring instrument housing close to the shoulder straps. The support layer is made of a hard material and bends inward to form a "D" - shaped structure together with the back-attaching layer.

[0014] Preferably, the back-attaching layer is composed of an outer frame made of a hard material and a tensile mesh structure stitched and fixed along the outer frame. Arc-shaped depressions are provided on both sides of the outer frame.

[0015] Preferably, the side of the vertical section of the outer frame is a slightly curved "S" - shaped frame, and the upper horizontal section of the outer frame is an arc-shaped frame that is recessed inward.

[0016] Preferably, the shoulder strap also includes an adjustment strap fixedly connected to the side wall of the outer frame at the lower part. The width of the shoulder strap is greater than the width of the adjustment strap, and the shoulder strap and the adjustment strap are detachably connected through a snap fastener.

[0017] Preferably, the radar bracket is rotatably connected to the measuring instrument housing through a receiving shaft. A locking groove is provided at the position where the receiving shaft extends into the measuring instrument housing, and a locking mechanism is installed in the locking groove. The locking mechanism is used to lock and control the receiving shaft.

[0018] Preferably, the locking mechanism includes:

[0019] A rotating wheel, which is rotatably connected to the wall of the locking groove. The rotating wheel is fixedly connected to one end of the receiving shaft extending into the measuring instrument housing;

[0020] An engaging claw, a torsion spring is sleeved between the engaging claw and its rotating shaft, and the engaging claw is engaged with the teeth of the rotating wheel under the elastic force of the torsion spring;

[0021] A locking block, the locking block is a conical rod rotatably connected in the locking groove. When the locking block is in the locked state, its axis is collinear with the center of the rotating wheel. At this time, the engaging claw just interferes with the teeth of the rotating wheel under the pushing action of the locking block.

[0022] Preferably, a locking rod is fixedly connected above the end of the locking block far from its rotating shaft. The locking rod passes through the locking groove and extends outwards from the radar frame. The radar frame is provided with a travel groove along the rotating direction of the locking rod at the position where the locking rod extends. The width of the travel groove is the same as the diameter of the locking rod. The locking rod also includes a holding handle fixedly connected to the rod body of the part extending out of the travel groove. The outer diameter of the holding handle is greater than the width of the travel groove.

[0023] Preferably, the travel groove further includes another arc groove with the center of the rotating shaft as the center and the distance from the center of the rotating shaft to the center of the locking rod as the radius, and the central angle of this arc groove is 180°.

[0024] Preferably, placing bases are fixedly connected to the vertical side wall and the top horizontal side wall of the radar frame. The lidar is detachably connected to the radar frame through the placing bases.

[0025] Preferably, placing grooves for storing the lidar are symmetrically opened at the upper end of the measuring instrument housing. The inner wall of the top of the placing groove is connected with internal threads, and the internal threads are in threaded cooperation with the external threads opened on the outer wall of the top of the lidar.

[0026] The beneficial effects of the present invention are as follows:

[0027] 1. The "D"-shaped structure formed between the support layer made of a hard material and the back-attached layer in the back sandwich not only prevents direct contact between the back of the staff and the measuring instrument housing, but also has a large gap. This allows the staff to free their hands during the process of carrying the measuring instrument, and the heat generated during the carrying process will not accumulate on the back. Instead, it can be dissipated out in time through the gap of the "D"-shaped structure. This not only reduces the sweating phenomenon caused by heat accumulation during the staff's movement and the resulting discomfort, but also avoids the heat conduction into the measuring instrument housing and affecting the operation of the main body of the measuring instrument.

[0028] 2. By setting placing bases on the radar frame, the lidar can be taken out from the placing bases when the mahogany selection work is not carried out, and stored in the placing grooves at the upper end of the measuring instrument housing. Then, the lidar is rotated, and the external threads at the top of the lidar are in threaded cooperation with the internal threads at the top of the placing grooves, so as to lock the lidar in the placing grooves. Thus, the wrapping of the measuring instrument housing can prevent the lidar from being damaged due to accidental collision during non-working hours, improving the use stability of the lidar.

[0036] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0037] As Figures 1 to 5 shown, an embodiment of the present invention provides a laser measurement device for processing redwood boards, including:

[0038] A measuring instrument housing 1, in which a measuring instrument main body is installed;

[0039] A radar bracket 2, which is also installed on the back main body, and a LiDAR 3 is installed on the radar bracket 2;

[0040] Shoulder straps 4, which are symmetrically and fixedly connected to the measuring instrument housing 1, and are used for staff to carry the measuring instrument housing 1 on the back;

[0041] It further includes:

[0042] A backpacking sandwich 5, which is fixedly connected between the measuring instrument housing 1 and the shoulder straps 4, and the backpacking sandwich 5 includes:

[0043] A back-attached layer 6, which is close to the back of the staff;

[0044] The support layer 7 is attached to the end face of the measuring instrument housing 1 close to the shoulder strap 4. The support layer 7 is made of a rigid material and bends inward to jointly form a "D" - shaped structure with the back - attaching layer 6.

[0045] As an implementation mode of the present invention, the back - attaching layer 6 is composed of an outer frame 8 made of a rigid material and a tensile mesh structure stitched and fixed along the outer frame 8. Arc - shaped depressions are provided on both sides of the outer frame 8.

[0046] As an implementation mode of the present invention, the side surface of the vertical section of the outer frame 8 is a slightly curved frame, and the upper horizontal section of the outer frame 8 is an arc - shaped frame that is recessed inward.

[0047] When conducting the selection work of mahogany in the forest farm area, the staff open the measuring instrument host inside the measuring instrument housing 1. After ensuring that the two lidar sensors 3 on the radar stand 2 are in normal working condition, they can start the selection operation by carrying the measuring instrument housing 1 on the back through the shoulder strap 4 fixedly connected to the measuring instrument housing 1. There is also a carrying sandwich 5 between the measuring instrument housing 1 and the staff's back. The "D" - shaped structure formed between the inward - concave support layer 7 made of hard material and the back - adhering layer 6 in the carrying sandwich 5 not only prevents direct contact between the staff's back and the measuring instrument housing 1, but also leaves a large gap. This allows the staff to free their hands during the movement of carrying the measuring instrument, and the heat generated during the carrying process will not accumulate on the back, but can be dissipated outward in time through the gap of the "D" - shaped structure. This not only reduces the sweating phenomenon caused by heat accumulation during the staff's movement, reduces the resulting discomfort, but also avoids the influence of heat conduction into the measuring instrument housing 1 on the operation of the measuring instrument host. Different from the support layer 7 made of all - hard material, only the outer frame 8 of the back - adhering layer 6 is made of the same light hard material as the support layer 7. The central part actually in direct contact with the staff's back is a net - surface structure stitched and fixed along the outer frame 8, and this net - surface structure is woven from high - tensile nylon wire. The two sides of the outer frame 8 made of hard material are concave in an arc shape inward, leaving room for the staff's shoulders to move. The slightly curved "S" - shaped vertical section of the outer frame 8 has the same bending amplitude as the natural bending curve of the human spine, and the inward - concave amplitude of the arc - shaped horizontal section is the same as the conventional curve of the human shoulder bones. This enables the back - adhering layer 6 to fit the staff's back as much as possible, dispersing the weight of the measuring instrument housing 1 to the entire back muscle group instead of concentrating on a certain part of the muscle, thus effectively relieving the staff's muscle fatigue and improving the staff's work efficiency. The net - surface structure woven from high - tensile nylon wire not only further enhances the breathability of the back - adhering layer 6, allowing the heat generated by the staff during the carrying process to quickly dissipate through the mesh holes of the net - surface structure, but also the compressive deformation generated when the net - surface contacts the back can make the back - adhering layer 6 fit the actual back curve of the staff more closely, further reducing the staff's carrying burden and relieving the staff's fatigue.

[0048] As an implementation mode of the present invention, the shoulder strap 4 further includes an adjustment strap 9 fixedly connected to the side wall of the outer frame 8 below. The width of the shoulder strap 4 is greater than the width of the adjustment strap 9, and the shoulder strap 4 and the adjustment strap 9 are detachably connected through a snap - fastener 10.

[0049] During operation, when the staff member just picks up the measuring instrument housing 1 through the shoulder strap 4, the length of the adjusting strap 9 can be adjusted so that the back-attaching layer 6 and the relatively wide part of the shoulder strap 4 can better fit the body. However, as the log exploration and selection work continues, the physical strength of the staff member is continuously consumed. Inevitably, the situation of being tired and needing to rest will still occur. When the staff member feels tired and sits down to rest, the buckle 10 design between the shoulder strap 4 and the adjusting strap 9 enables the staff member to quickly remove the carried measuring instrument housing 1 even when already sitting, facilitating the staff member to rest and thus quickly recover physical strength to resume the rosewood selection operation.

[0050] As an embodiment of the present invention, the radar frame 2 is rotatably connected to the measuring instrument housing 1 through a receiving shaft 11. A locking groove 12 is provided at the position where the receiving shaft 11 extends into the measuring instrument housing 1. A locking mechanism 13 is installed in the locking groove 12, and the locking mechanism 13 is used to lock and control the receiving shaft 11.

[0051] As an embodiment of the present invention, the locking mechanism 13 includes:

[0052] A rotating wheel 14, which is rotatably connected to the groove wall of the locking groove 12, and the rotating wheel 14 is fixedly connected to one end of the receiving shaft 11 extending into the measuring instrument housing 1;

[0053] An engaging claw 15, a torsion spring is sleeved between the engaging claw 15 and its rotating shaft, and the engaging claw 15 is engaged with the teeth of the rotating wheel 14 under the elastic force of the torsion spring;

[0054] A locking block 16, which is a tapered rod rotatably connected in the locking groove 12. When the locking block 16 is in the locked state, its axis is collinear with the center of the rotating wheel 14. At this time, the engaging claw 15 just interferes with the teeth of the rotating wheel 14 under the pushing action of the locking block 16.

[0055] As an embodiment of the present invention, a locking rod 17 is fixedly connected above the end of the locking block 16 far from its rotating shaft. The locking rod 17 passes through the locking groove 12 and extends out of the radar frame 2. A travel groove 18 is provided at the position where the locking rod 17 extends out of the radar frame 2 along the rotation direction of the locking rod 17. The width of the travel groove 18 is the same as the diameter of the locking rod 17. The locking rod 17 further includes a holding handle 19 fixedly connected to the part of the rod body extending out of the travel groove 18, and the outer diameter of the holding handle 19 is greater than the width of the travel groove 18.

[0056] As an embodiment of the present invention, the travel groove 18 further includes another arc groove with the center of the rotating shaft as the center and the distance from the center of the rotating shaft to the axis of the locking rod 17 as the radius, and the central angle of this arc groove is 180°.

[0057] During operation, the forestry areas that require the selection of rosewood are usually far from urban areas. Therefore, before the selection operation, it is often necessary to drive a vehicle to the vicinity of the target forestry area with the measuring instrument housing 1 first, and then officially carry out the rosewood selection operation. To facilitate the carrying of the measuring instrument housing 1, the radar frame 2 is designed to be rotatably connected to the measuring instrument housing 1 through the receiving shaft 11. When preparing to set off for the rosewood forest, the staff can rotate the holding handle 19 clockwise, driving the locking rod 17 to rotate along the travel groove 18. The relatively thick holding handle 19 is convenient for the staff to pull, making it easier for the locking block 16 fixedly connected to the locking rod 17 to rotate along with it and disengage from the meshing claw 15. At this time, the locking mechanism 13 in the locking groove 12 is in the unlocked state. The staff can rotate the radar frame 2 originally located at the upper end of the measuring instrument housing 1 clockwise and transfer it to the lower part of the measuring instrument housing 1, thus saving space and facilitating carrying. During the process of rotating the radar frame 2 and driving the receiving shaft 11 to rotate together, although the meshing claw 15 is still in contact with the teeth of the rotating wheel 14 under the action of the torsion spring, the deflection force provided by the torsion spring is much smaller than the pressure generated when the teeth of the rotating wheel 14 are in contact with the meshing claw 15. Therefore, it will not interfere with the rotation of the radar frame 2. When the radar frame 2 rotates to the directly lower part of the measuring instrument housing 1, the holding handle 19 also just arrives at the other end of the travel groove 18 and is limited by the travel groove 18, thus prompting the staff that it has been rotated to the storage position and can be ready to set off for the rosewood forest. When arriving at the forest and preparing to carry out the rosewood selection work, the staff only needs to rotate the radar frame 2 reversely. After the radar frame 2 rotates to the upper part of the measuring instrument housing 1, then pull the holding handle 19 along the travel groove 18 to drive the locking rod 17 to rotate, so that the locking block 16 abuts against the meshing claw 15. At this time, the meshing claw 15 is supported by the locking block 16 and meshes with the teeth of the rotating wheel 14 to cause interference, playing a role in locking the rotating wheel 14. The receiving shaft 11 fixedly connected to the rotating wheel 14 is also locked accordingly, thus completing the extension of the radar frame 2. The staff can then carry the measuring instrument housing 1 on their back and start to carry out the rosewood selection work in the forestry area.

[0058] As an implementation manner of the present invention, placing bases 20 are fixedly connected to the vertical side wall and the top horizontal side wall of the radar frame 2, and the lidar 3 is detachably connected to the radar frame 2 through the placing bases 20.

[0059] As an implementation manner of the present invention, placing grooves 21 for storing the lidar 3 are symmetrically opened at the upper end of the measuring instrument housing 1. The inner wall of the top end of the placing groove 21 is connected with internal threads, and the internal threads are in threaded cooperation with the external threads opened on the outer wall of the top end of the lidar 3.

[0060] During operation, among the components of the backpack laser measuring instrument, the cost of the main body of the measuring instrument and the lidar 3 is the highest. The main body of the measuring instrument is hidden in the measuring instrument housing 1 and is not easily damaged, while the lidar 3 is exposed outside and is more likely to collide with the outside world. Therefore, a placement base 20 is provided on the radar mount 2 so that the lidar 3 can be taken out from the placement base 20 when not selecting rosewood, and stored in the placement groove 21 at the upper end of the measuring instrument housing 1. Then, the lidar 3 is rotated, and through the thread fit between the external thread at the top of the lidar 3 and the internal thread at the top of the placement groove 21, the lidar 3 is locked in the placement groove 21, so as to avoid damage to the lidar 3 caused by accidental collision during non-working hours by the protection of the measuring instrument housing 1, improving the use stability of the lidar 3.

[0061] The above shows and describes the basic principles, main features and remarkable advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above specific embodiments. Without departing from the spirit and scope of the present invention, the present invention may also be subject to various changes and improvements to adapt to different use environments and customer requirements, and these changes and improvements all fall within the protection scope of the present invention. The protection scope of the present invention is defined by the appended claims and their equivalents.
