Description

Technical Field

[0001] The invention relates to the technical field of fir pruning mechanical equipment, and in particular to a fir pruning height clamp ring and a use method thereof. Background Art

[0002] Chinese fir is an important fast-growing commercial timber species in southern my country and plays a pivotal role in my country's forestry production. With the development of ecological civilization in my country, the management of Chinese fir plantations is no longer aimed at obtaining small-diameter timber in the short term, but has turned to focus more on cultivating large-diameter timber and improving timber quality. In order to obtain large-diameter timber with large trunk thickness, straight trunks and no scars, it is necessary to consider timely removal of trunk side branches during the growth of the forest, also known as pruning.

[0003] During the growth process of Chinese fir, as the tree height increases, the side branches at the bottom of the trunk will die regularly from bottom to top. However, after the side branches die, they will not fall off in time, but will remain on the trunk for a long time, resulting in serious scarring of the trunk, which seriously affects the quality of the trunk and the output of wood boards. If the dead side branches are removed in time, as the trunk grows, the original attachment points of the side branches on the trunk can be slowly wrapped up, which will not only make the trunk surface smooth and improve the quality of the trunk, but also greatly increase the output of wood boards. In order to further improve the quality of large-diameter Chinese fir forest stands, a large number of studies and forestry production practices have attempted to remove the branches that have not completely died and survived in the middle and lower parts of the trunk in advance. It is necessary to determine the pruning height. At present, there is no unified standard for the pruning height of Chinese fir. The determination of pruning height is currently based on the trunk diameter. For example, the pruning height is below 8cm, 10cm or 12cm in trunk diameter. Currently, there are no corresponding mature tools or devices, and operators mainly make simple clamps by themselves using wooden strips or PVC tubes, for example, to make fixed diameters of 8 cm or 12 cm. The diameter of a single clamp is single, and the diameter size cannot be adjusted at any time according to needs, resulting in low reuse rate. In addition, multiple attempts to clamp the tree trunk are required to find the trunk position of the target size (for example, the trunk position of 8 cm or 12 cm in diameter), and the work efficiency is low.

[0033] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0034] Please refer to Figures 1 to 3 , the embodiments provided by the present invention are:

[0035] A fir pruning height clamp comprises an up-and-down walking component 1 and a diameter measuring component 2. The up-and-down walking component 1 can move up and down along a tree trunk, while the diameter measuring component 2 can measure the diameter of the tree trunk in real time.

[0036] Specifically, with respect to the specific structure of the up and down walking component 1, the up and down walking component 1 includes an enclosing frame 11, and the enclosing frame 11 includes an enclosing frame body 12 and a movable frame plate 13. The enclosing frame body 12 and the movable frame plate 13 are detachably connected, and the enclosing frame body 12 and the movable frame plate 13 are assembled into a closed shape. When used on site, the enclosing frame 11 surrounds the tree trunk.

[0037] Preferably, the shape of the enclosing frame 12 is circular, polygonal or square, which can enclose the tree trunk and facilitate the installation of the roller telescopic assembly 14. Specifically, the enclosing frame 12 and the movable frame plate 13 are detachably connected by screws and nuts, which is convenient for disassembly and has a stable structure.

[0038] Furthermore, the up-and-down walking assembly 1 also includes four roller telescopic assemblies 14, and the four roller telescopic assemblies 14 are distributed on two intersecting straight lines. Through the four rollers 15 located on the two intersecting straight lines, two V-shaped tops are formed for the tree trunk, which can prevent the up-and-down walking assembly 1 from running off due to insufficient roundness of the tree trunk. Preferably, the angle between the two intersecting straight lines on which the four roller telescopic assemblies 14 are distributed is 45° to 90°, forming two V-shaped tops for the tree trunk, and having good structural stability.

[0039] Preferably, the roller 15 is vertically placed in a vertical plane passing through the intersection line where it is located, and its rotation axis is horizontally arranged and perpendicular to the intersection line where it is located. Under this structure, the up and down walking component 1 moves straight up and down, and the up and down walking component 1 can be installed on an external linear lifting pruning equipment for use, or it can be driven by the telescopic rod 31 to move up and down.

[0040] Alternatively, the roller 15 rotates along the intersection line through which it passes. With this structure, the up-down walking assembly 1 can also climb up in a spiral around the tree trunk, and the up-down walking assembly 1 can be installed on an external spiral ascending pruning device for use.

[0041] Specifically, with regard to the specific structure of the roller telescopic assembly 14, the roller telescopic assembly 14 includes a roller 15 and a spring 16. The four rollers 15 are all located on the inner side of the enclosing frame 12. The rollers 15 are telescopically slidably arranged on the enclosing frame 11 through the springs 16. The rollers 15 are in rolling contact with the tree trunk to prevent damage to the bark. The rollers 15 are slidably arranged on the enclosing frame 11 along a cross straight line, and the springs 16 are used to ensure that the rollers 15 can still contact the trunk as the diameter of the trunk changes.

[0042] Further, the roller telescopic assembly 14 further comprises a support rod 17 and a limit nut 18, wherein the support rod 17 is axially slidably arranged on the surrounding frame 12, the roller 15 is rotatably arranged on the inner end of the support rod 17, the spring 16 is sleeved on the support rod 17 and is located between the roller 15 and the surrounding frame 12, and the limit nut 18 is fixed on the outer end of the support rod 17. The support rod 17 is a bare rod, and its outer end is provided with an external thread, and the inner end of the support rod 17 is provided with a flange to prevent the spring 16 from coming out, if the snap ring is not fixed on the trunk, under the action of the spring 16, the roller 15 and the support rod 17 slide toward the inner side of the surrounding frame 11 until the limit nut 18 touches the surrounding frame 11; if the snap ring is fixed on the trunk, under the action of the trunk, the roller 15 and the support rod 17 slide toward the outer side of the surrounding frame 11, but under the action of the spring 16, the roller 15 always contacts the trunk.

[0043] More specifically, the roller telescopic assembly 14 also includes a fixed block 19, which is fixed on the outer side of the enclosing frame 12, and the support rod 17 is axially slidably set on the fixed block 19. The fixed block 19 and the enclosing frame 11 support the sliding support rod 17, so that the support rod 17 has good force stability and the overall structural stability of the retaining ring is good.

[0044] Further, with regard to the specific structure of the diameter measuring assembly 2, the diameter measuring assembly 2 includes two detection plates 21 and a distance measuring sensor 24. The two detection plates 21 are fixed on the two roller telescopic assemblies 14 located on the same intersecting straight line, and the transmitting end and the receiving end of the distance measuring sensor 24 are respectively fixed on the two detection plates 21. A set of distance measuring sensors 24 and detection plates 21 are fixed by two roller telescopic assemblies 14 located on the same intersecting straight line, and the distance between the two detection plates 21 changes as the distance between the two rollers 15 changes, thereby realizing the detection of the trunk diameter.

[0045] For details, please refer to Figure 2 and Figure 3The detection plate 21 is a spoon-shaped plate, which includes an arc-shaped plate 22 and a flat plate 23 connected in one piece. The openings of the arc-shaped plate 22 are arranged opposite to each other, and the roller 15 is located inside the arc-shaped plate 22. Preferably, after the two spoon-shaped plates and the two roller telescopic assemblies 14 are installed, the distance between the flat plates 23 of the two spoon-shaped plates is equal to the distance between the inner sides of the rollers 15 on the two roller telescopic assemblies 14 installed thereon. In this case, the distance detected by the distance measuring sensor is the actual measured trunk diameter.

[0046] Alternatively, the detection plate 21 is in the shape of a flat plate. In this case, the distance detected by the distance measuring sensor 24 minus twice the distance from the flat plate to the contact point between the roller 15 connected thereto and the tree trunk is the actual trunk diameter.

[0047] In addition, the two detection plates 21 and a set of distance measuring sensors 24 are also fixed on the two roller telescopic components 14 of another intersecting straight line, which can detect two trunk diameter values ​​at the same time. Through these two trunk diameter values, a more reasonable trunk diameter value can be fitted to make the value more reliable.

[0048] Specifically, the distance measuring sensor 24 is a laser sensor or an ultrasonic sensor.

[0049] Furthermore, the diameter measuring assembly 2 further comprises a display screen 25, and the distance measuring sensor 24 is electrically connected to the display screen 25, and the measured trunk diameter value can be observed in real time through the display screen 25. The display screen 25 is arranged at the bottom of the trunk, and a person standing on the ground can observe it. The display screen 25 can be powered by a battery.

[0050] In addition, if the up and down walking component 1 and the diameter measuring component 2 are not fixed on the external pruning equipment to work, in order to check whether the pruning height of the external pruning equipment is reasonable, it also includes a lifting component 3, and the lifting component 3 includes a telescopic rod 31. The up and down walking component 1 is fixed on the top of the telescopic rod 31, and the telescopic rod 31 is extended and retracted to drive the up and down walking component 1 and the diameter measuring component 2 to move straight up and down.

[0051] Furthermore, in order to know the current height of the up-and-down walking assembly 1, a length scale line is provided on the telescopic rod 31, so that a person standing on the ground can observe and record the height value in real time.

[0052] Furthermore, in order to facilitate the fixation of the telescopic rod 31, the lifting assembly 3 also includes a tripod 32, and the bottom of the telescopic rod 31 is fixed on the tripod 32, so that the telescopic rod 31 can stand upright without the need for human support.

[0053] Furthermore, in order to realize automatic extension and retraction of the telescopic rod 31, the lifting assembly 3 also includes an electric control panel and a switch button 33. The telescopic rod 31 is an electric telescopic rod. The electric control panel is electrically connected to the electric telescopic rod. The switch button 33 is electrically connected to the electric control panel. The switch button 33 is fixed to the lower part of the telescopic rod 31. A person standing on the ground controls the switch button 33 to realize control of the electric telescopic rod, and the operation is convenient and labor-saving.

[0054] Furthermore, in order to supply power to the lifting assembly 3 , the lifting assembly 3 further includes a back-type battery pack 34 , and the back-type battery pack 34 is electrically connected to the electric control assembly to supply power to the electric telescopic rod and also to the display screen 25 .

[0055] Please refer to Figure 4 As shown, the present invention also provides a method for using the above-mentioned fir pruning height clamp, the method comprising:

[0056] S1 assembles the movable frame plate and the surrounding frame body to surround the tree trunk into a surrounding frame, so that the rollers of the four roller telescopic assemblies are all against the tree trunk;

[0057] The S2 up-and-down walking component moves upward along the tree trunk under the action of external force, and the distance sensor returns the measured trunk diameter value in real time;

[0058] Among them, the external force refers to the external pruning equipment or the upper and lower telescopic rods.

[0059] The clamp can transmit the trunk diameter value in real time while moving up and down, which is convenient to use.

[0060] In view of the difference in external force, further, in S2, "the up and down walking component moves upward along the trunk under the action of external force" is specifically:

[0061] The up and down walking components are fixed on the external pruning equipment and move upward along with the external pruning equipment.

[0062] The pruning equipment can be moved and the trunk diameter value can be transmitted back in real time.

[0063] Alternatively, in S2, “the up-and-down walking component moves upward along the trunk under the action of external force” is specifically:

[0064] The up-and-down walking assembly is fixed on the telescopic rod and moves upward with the telescopic rod; wherein the telescopic rod is manual or electric. Specifically, the telescopic rod is provided with a length scale line, which can check the value of the current height of the up-and-down walking assembly, so as to predict the pruning height.

[0065] The fir pruning height clamp ring and the use method provided by the present invention have the following beneficial effects:

[0066] 1. The diameter measuring component 2 fixed on the up-and-down walking component 1 can transmit the trunk diameter value in real time when the up-and-down walking component 1 moves up and down along the trunk;

[0067] 2. The up and down walking assembly 1 can be fixed on an external pruning device, or can be fixed on a self-set telescopic rod 31 to move up and down;

[0068] 3. The four roller telescopic assemblies 14 located between the two crosses are used to tighten the tree trunk, so that two V-shaped clamps are formed on the tree trunk, thereby effectively preventing the up and down walking assembly 1 from running off;

[0069] 4. By fixing the clamp ring on the external pruning equipment, the trunk diameter can be detected while pruning;

[0070] 5. By setting a length scale line on the telescopic rod 31, the height of the tree trunk pruning can be easily checked and predicted.
