Description

Technical Field

[0001] The invention relates to the technical field of bark sampling, and in particular to a device for sampling bark samples at different heights of forestry trees. Background Art

[0002] Bark sampling is a common research method in forest ecology, plant pathology, wood science and other fields. The correct sampling method can ensure the representativeness and accuracy of the sample, thereby improving the reliability of the research results. Therefore, when focusing on the growth of forestry trees, the bark of the tree can generally be obtained through a bark sampler.

[0003] Chinese patent authorization announcement number CN115993265A discloses a tree bark sample collection device and method, including: a housing, a motor, a sampling drill, a sampling shovel, a drill chuck for mounting the sampling drill, a shovel mounting head for mounting the sampling shovel, and a reciprocating transmission mechanism for converting rotation into linear reciprocating motion to drive the sampling shovel to reciprocate for shoveling, which can collect bark samples. Compared with manual scraper sampling, the operation is labor-saving, fast, and can stably maintain the size of each sample.

[0004] The above-mentioned prior art solutions have the following shortcomings: the device is easily restricted by the height of the operator during actual use, so that the height for sampling the tree bark is limited, making it difficult to perform multiple sampling at different heights. Moreover, since most forestry trees grow outdoors, the outer surface of their bark is often stained with stains, etc. When testing the bark, in order to avoid the influence of external factors, it is generally necessary to clean the bark. However, in this device, the bark is directly peeled off, and then the outer surface cannot be automatically cleaned when the bark is obtained. Therefore, there is room for improvement.

The magnetic plate, the metal plate 1, etc. can be used to limit and fix the bark to reduce the collision and friction between the barks during the movement of the device and reduce damage. On the other hand, the interlayer storage method can be used to prevent confusion caused by mutual squeezing between the barks, so as to facilitate clear viewing of the sampled barks corresponding to different positions and improve the accuracy of subsequent research.

Obviously, the described embodiments are only part of the embodiments of the invention, not all of the embodiments. Based on the embodiments of the invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the invention.

[0034] Embodiment 1

[0035] In order to solve the problem that the existing sampling device for sampling the skin samples of forestry trees at different heights is not easy to sample at different heights, the following scheme is disclosed, specifically as follows: Figure 1 , Figure 2 , Figure 3 As shown:

[0043] The linkage opening and closing mechanism 15 includes a gear 1501 installed at the top of the fixed box 7, and one side of the gear 1501 is meshed with a longitudinal tooth plate 1502, the top of the longitudinal tooth plate 1502 extends to the outside of the fixed box 7, and the bottom of the longitudinal tooth plate 1502 extends to the inside of the exhaust tube 9 and is connected to a baffle 1504, the front side of the baffle 1504 is against one end of the fixed tube 10, and the other side of the gear 1501 is meshed with two parallel horizontal tooth plates 1503, and one end of the horizontal tooth plate 1503 They are connected to one side of the T-shaped rod 13 located above, the outside of the horizontal tooth plate 1503 is sleeved with a guide sleeve 1505, and the top of the guide sleeve 1505 is connected to the top of the sampling hole 5, the horizontal tooth plate 1503 and the longitudinal tooth plate 1502 are vertically distributed, and the upper and lower ends of the baffle 1504 are provided with magnets. When the baffle 1504 moves upward or downward, the baffle 1504 uses the magnet to adsorb and fix with the upper end surface or the lower end surface inside the exhaust cylinder 9, thereby realizing the opening and closing adjustment of the fixed tube 10;

[0044] The digging assembly 6 includes two upper turning rods 601 which are parallelly distributed on the two inner side walls of the sampling hole 5, and the two upper turning rods 601 are rotatably connected to the inner side wall of the sampling hole 5 through a rotating shaft, the inner sides of the two upper turning rods 601 are coaxially connected to the lower turning rods 602, the outer ends of the two upper turning rods 601 and the two lower turning rods 602 extend to the outside of the sampling hole 5, the outer sides of the two upper turning rods 601 and the two lower turning rods 602 are connected to spring ropes 603, and one end of the spring ropes 603 is connected to the outer wall of the movable box 1 to ensure that each group of upper turning rods 601 and lower turning rods 602 are in an open state, the outer ends of the two upper turning rods 601 are commonly connected to an upper cutting knife 604, and the outer ends of the two lower turning rods 602 are commonly connected to a lower cutting knife 605;

[0045] The upper cutter 604 has the same shape and size as the lower cutter 605, the cross-sections of the upper cutter 604 and the lower cutter 605 are semi-elliptical, the cutting surfaces of the upper cutter 604 and the lower cutter 605 are curved structures, and the dirt extraction cover 12 faces the center position between the upper cutter 604 and the lower cutter 605;

[0046] During the movement of the two T-shaped rods 13, the front sides of the two T-shaped rods 13 contact the inner sides of the upper flip rod 601 and the lower flip rod 602 respectively, and drive the upper flip rod 601 and the lower flip rod 602 to flip and approach each other, so that the upper cutting knife 604 and the lower cutting knife 605 approach each other and perform arc cutting on the tree bark.

[0047] In this embodiment, when the movable box 1 stops during use, the exhaust fan 8 is started, and the electric push rod 14 is extended, so that the extension tube 11 moves along the outside of the fixed tube 10 toward the tree. As the extension tube 11 moves, the T-shaped rod 13 moves synchronously, and the upper T-shaped rod 13 pulls the horizontal tooth plate 1503 to move synchronously outward, so that the gear 1501 rotates, and the longitudinal tooth plate 1502 moves upward under the meshing action, and then the baffle 1504 moves upward synchronously, and the baffle 1504 is fixed after rising by the effect of the magnet, so that the fixed tube 10 and the exhaust cylinder 9 are connected, and then the suction force generated by the rotation of the exhaust fan 8 is moved from the exhaust hood 12 along the extension tube 11 to the fixed tube 10 and the exhaust cylinder 9, so that the exhaust hood 12 generates suction on the stains on the outer surface of the sampled bark in the process of approaching the sampled bark, so as to achieve a cleaning effect;

As the bark is cut off, the sampling bark is automatically picked up under the suction operation of the sewage extraction hood 12;

[0049] Start the electric push rod 14 to shorten and reset, so that the extension tube 11 drives the sewage hood 12 to reset, and then the T-shaped rod 13 is reset to achieve the reset of the two spring ropes 603. With the movement of the T-shaped rod 13, the linkage opening and closing mechanism 15 moves in the opposite direction, so that the baffle 1504 is reset and one end of the fixed tube 10 is blocked, so that the suction force inside the fixed tube 10 disappears, and then the sewage hood 12 loses its attraction to the bark, and then the bark automatically falls off to the storage groove 16 for storage.

[0050] Embodiment 3

[0051] This embodiment is different from the first and second embodiments. The interlayer fixing assembly 18, the magnetic plate 19, the metal plate 20, etc. are used to facilitate the interlayer stacking of bark at different sampling positions for subsequent research and use. Figure 2 , Figure 7 , Figure 8 and Fig. 9 , Fig.10 As shown:

[0052] A storage groove 16 is provided at the bottom end of the sampling hole 5, and a box door 17 is provided on the outside of the storage groove 16, and the box door 17 is located below the limiting component 2. The sewage extraction hood 12 is located directly above the storage groove 16 in the initial position, and the two side walls inside the storage groove 16 are provided with a partition fixing component 18.

[0053] The partition fixing assembly 18 includes five flip partitions 1801 which are evenly spaced and longitudinally distributed on the inner wall of the storage slot 16, and one side of the flip partition 1801 is rotatably connected to the inner wall of the storage slot 16 via a connecting shaft, and a plurality of connecting ropes 1803 are distributed in parallel at the outer top end of the bottom flip partition 1801, and one end of the connecting ropes 1803 is connected to the bottom end of the storage slot 16, and a plurality of connecting ropes 1802 are connected in parallel between the outer top end of the upper flip partition 1801 and the inner top end of the adjacent flip partition 1801 below.

[0054] In the initial state, the connecting rope 1803 is inclined, and the lengths of the connecting rope 1802 and the connecting rope 1803 are the same. After the cut bark enters the storage groove 16, the connecting rope 1803 is pressed down under the action of gravity and impact force, causing the connecting rope 1803 to deform, and then pulling the lowest flip partition 1801 to flip, thereby covering the bark, and causing one end of the connecting rope 1802 on the flip partition 1801 to move and be distributed in an inclined state, and then the next bark is received.

[0055] The inner side of the flip partition 1801 is fixedly connected with a metal plate 20, and the inner side of the metal plate 20 is adsorbed with a magnetic plate 19, and the inner side of the magnetic plate 19 is fixedly connected to the inner wall of the storage slot 16. The flip partition 1801 is inclined in the state, that is, the side away from the connecting axis approaches the inner wall of the storage slot 16, and the side of the storage slot 16 close to the connecting axis is fixedly connected with a metal plate 21. When the flip partition 1801 is flipped, the metal plate 21 approaches the magnetic plate 19, and the metal plate 20 moves away from the magnetic plate 19.

[0056] In this embodiment, when in use, the sampled bark is impacted by falling in the storage tank 16, so that the bark presses down the two groups of connecting ropes 1803 on the left and right, so that the connecting ropes 1803 are deformed, and then one end of the connecting rope 1803 generates a pulling force on the bottom flip partition 1801, so that the bottom flip partition 1801 flips to cover the fallen sampled bark. At this time, as the flip partition 1801 flips, the metal plate 21 approaches the direction of the magnetic plate 19, so that the metal plate 1 20 and the magnetic plate 19 are separated from each other, and at the same time The flipped flip partition 1801 pulls one end of the connecting rope 1802 to move, so that the connecting rope 1802 forms an inclined shape, and then when the next sampled bark falls, the connecting rope 1802 is deformed, so that each layer of the flip partition 1801 is automatically flipped after each sampled bark falls, thereby achieving a layer-by-layer stacking and storage effect for multiple sampled barks to prevent confusion between the sampled barks. Finally, when the device descends to the lower end of the tree, the box door 17 is opened by pulling outward to facilitate the taking of the sampled bark in the storage slot 16.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
