Description

Technical Field

[0001] The present application relates to the technical field of collection tools, and in particular to a plant specimen collection device. Background Art

[0002] Plant biodiversity surveys often require collecting wild plant sample information in the wild for identification and research of wild plant samples to promote plant community diversity surveys and exchanges. In the sampling of wild plant specimens, some trees and shrubs need to sample branches, while some plants need to sample their roots and rhizomes, which requires the use of tools to collect and sample.

[0003] The existing collection and sampling tools have relatively simple functions. For example, when collecting branches at higher places, long branch shears are needed for cutting, when collecting shorter shrubs, ordinary branch shears are used for cutting, and when collecting and sampling the rhizomes of plants, they need to be dug with a shovel. Therefore, it is necessary to carry multiple types of tools when collecting and sampling, especially long branch shears. Due to their long length, they take up a large space when carried, making it inconvenient for operators to travel.

Detailed implementation manners

[0040] In order to make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0041] Embodiment 1

[0042] As Figure 1 - Fig.13 shown, a plant specimen collection device proposed in Embodiment 1 of the present application includes:

[0043] A head rod 1, on which a shearing assembly 2 is installed. The shearing assembly 2 includes a static cutting plate 201 fixedly installed on the head rod 1. A movable rod 202 is hinged on the head rod 1. A movable cutting plate 203 is installed on the movable rod 202. A connecting spring 204 is installed between the movable rod 202 and the head rod 1. A plate body is installed on the head rod 1. The movable rod 202, the static cutting plate 201, and the connecting spring 204 are all installed on this plate body. The movable cutting plate 203 and the connecting spring 204 are respectively located on both sides of the hinge point of the movable rod 202. The connecting spring 204 forces the movable rod 202 to move away from the head rod 1, so that in the normal state of the device, the movable cutting plate 203 and the static cutting plate 201 are in an open state. By pressing the movable rod 202, the movable cutting plate 203 is close to the static cutting plate 201, and the branches are sheared by the edges of the two, so that the device can be used normally;

[0044] The tail rod 3 is provided with a shovel plate 4, the end of which is a pointed tip. The shovel plate 4 is used to shovel the soil. When the tail rod 3 is in use, the shovel plate 4 is used to dig and shovel the soil at the root of the plant, so that the device can collect and sample the root of the plant;

[0045] The extension rod 5 has a threaded block 501 installed at one end and a threaded hole 502 opened at the other end. The head rod 1 also has a threaded hole 502 opened, and the tail rod 3 is also installed with a threaded block 501. The extension rod 5 is used to connect the head rod 1 with the tail rod 3. When in use, when it is necessary to cut branches at a high place, the extension rod 5 is connected to the head rod 1 through the threaded block 501, and connected to the tail rod 3 through the threaded hole 502. If the height is not enough, the extension rod 5 can be further connected so that the overall length of the device can contact the branches that need to be collected;

[0046] The driving rod 6 is slidably mounted on the extension rod 5, and a convex plate 601 is mounted on the free end of the movable rod 202. A through groove 602 is provided on the driving rod 6 for accommodating the convex plate 601 and the rod body of the movable rod 202. When the driving rod 6 slides, the inner wall of the through groove 602 contacts the movable rod 202 to make the movable rod 202 rotate. Due to the push of the connecting spring 204, the movable rod 202 is in a tilted state in the normal state, and the driving rod 6 is in a position where the movable rod 202 is closer to the head rod 1. When the driving rod 6 is slid backward, the inner wall of the through groove 602 contacts the movable rod 202, forcing the movable rod 202 to gradually approach the head rod 1, thereby enabling the movable cutting plate 203 to approach the static cutting plate 201, so that the device can cut the branches, and when the inner wall of the through groove 602 moves to the convex plate 601, the convex plate 601 restricts the sliding of the driving rod 6, thereby reducing the possibility of separation of the driving rod 6 and the movable rod 202, and increasing the practicality of the device.

[0047] When the device is carried, the head rod 1, the tail rod 3 and the extension rod 5 can be disassembled and carried separately. Compared with the existing tools, it can save the carrying space of the long branch shears and is more convenient for operators to carry;

[0048] Compared with the prior art, when in use, a shearing assembly 2 is installed on the first rod 1 to form a branch shear, and a shovel plate 4 is installed on the tail rod 3 to enable it to function as a shovel. When it is necessary to collect samples from high branches, the first rod 1 and the tail rod 3 are connected by an extension rod 5. After the connection is completed, the entire device functions as a long branch shear. At this time, the driving rod 6 is pulled to resist the movable rod 202, thereby driving the shearing assembly 2. When in use, the device can be disassembled and carried, which is convenient for the operator to carry the device and operate it.

[0049] Embodiment 2

[0050] like Figure 3 and Fig.10 As shown, the second embodiment is based on the first embodiment and further discloses the head rod 1, the tail rod 3, the shovel plate 4 and the extension rod 5. In the second embodiment, the driving rod 6 includes a sliding sleeve 603 slidably mounted on the extension rod 5, the sliding sleeve 603 is hinged with a mounting rod 604, a through groove 602 is provided on the mounting rod 604, and a connecting block 605 for inserting into the through groove 602 is installed on one side where the mounting rod 604 is hinged with the sliding sleeve 603, and a shielding plate 606 is threadedly connected to the connecting block 605. , the length of the shielding plate 606 is greater than the width of the through slot 602, an extension sleeve 301 is slidably mounted on the tail rod 3, an extension rod 302 is hinged on the extension sleeve 301, a through slot 602 is also provided on the extension rod 302, a connecting block 605 and a shielding plate 606 are also mounted on the extension rod 302, when in use, the driving rod 6 can also be split into multiple sections, divided into multiple mounting rods 604, and an extension rod 302 is mounted on the tail rod 3, and a connecting block 605 and a shielding plate 606 are also mounted on the extension rod 302;

[0051] When installing the device, first rotate the shielding plate 606 to a position where the length direction of the shielding plate 606 is parallel to the length direction of the through-slot 602, so that the mounting rod 604 can be mounted on the connecting block 605, and then rotate the shielding plate 606 to rotate the length direction of the shielding plate 606 to the width direction of the through-slot 602, thereby blocking the mounting rod 604 and limiting the rotation of the mounting rod 604. The sliding sleeve 603 is slidably mounted on the extension rod 5, and the extension sleeve 301 is also slidably mounted on the tail rod 3, which will not affect the sliding of the entire driving rod 6. When in use, the driving rod 6 can also be disassembled and combined. When in use, it is not only convenient to carry the device, but also does not affect the normal use of the device, so that the operator can drive the driving rod 6 even if he holds the tail rod 3 with his hand, which further increases the convenience of the device when in use and increases the practicality of the device.

[0052] like Figure 8 and Fig. 9 As shown, in the second embodiment, the extension rod 302 is slidably mounted with a sliding rod 303 in the through slot 602, and a clamping plate 304 is rotatably mounted on the sliding rod 303. The sliding rod 303 is slidably mounted on the extension rod 302 along the length direction of the through slot 602, and the clamping plate 304 rotates along the axis of the sliding rod 303.

[0053] The shovel plate 4 includes a main board 401 installed on the clamping plate 304, hinged plates 402 are hinged on both sides of the main board 401, and a sub-board 403 is hinged on the free side of the hinged plate 402. The sum of the widths of the sub-boards 403 is consistent with the width of the main board 401. A plug hole 404 is provided on the side of the sub-board 403 and the main board 401 away from the clamping plate 304. The shovel plate 4 also includes a shovel head plate 405, and a plug rod 406 for being inserted into the plug hole 404 is installed on the shovel head plate 405. A clamp plate 407 for contacting the main board 401 is installed on the shovel head plate 405. A through hole 408 is provided on the clamp plate 407 and the main board 401, and a limiting rod 409 is inserted in the through hole 408. The axis is perpendicular to the axis of the socket 404, and the clamping plates 407 are located on both sides of the shovel head plate 405. The gap between the clamping plates 407 is used to accommodate the main board 401, the hinged plate 402 and the auxiliary plate 403. When in use, the auxiliary plate 403 and the hinged plate 402 are rotated to make them parallel to the main board 401, and then the insertion rod 406 is aligned with the socket 404 to connect the shovel head plate 405 with the main board 401. In the process, the gap of the clamping plates 407 clamps the main board 401, and then the limiting rod 409 is inserted into the through hole 408 to limit the tendency of the shovel head plate 405 to move away from the main board 401, so that the shovel plate 4 can be formed, so that the tail rod 3 can form a shovel effect;

[0054] A unified plate 7 is installed on the extension rod 302, and a unified rod 8 for being inserted into the socket 404 is installed on the unified plate 7. When the unified rod 8 is inserted into the socket 404, a cavity for accommodating the shovel head plate 405 and the limiting rod 409 is formed between the unified plate 7, the main plate 401, the hinged plate 402 and the auxiliary plate 403. The shovel head plate 405 is formed by two triangular plates, one of which is equipped with a rod body, and the other triangular plate is provided with a channel for accommodating the above-mentioned rod body, so that the shovel head plate 405 can be further split, and the axis of the channel is perpendicular to the axis of the socket 404. When the plug rod 406 is inserted into the socket 404, the two triangular plates are connected. The tendency of the angle plates to separate is also limited, which further facilitates the accommodation of the device. When the shovel is used and needs to be stored, the limiting rod 409 is separated from the through hole 408, and the shovel head plate 405 is also disassembled. Then, the auxiliary plate 403 and the hinged plate 402 are rotated to form a cavity between the two and the main plate 401, and the limiting rod 409 and the shovel head plate 405 are placed in the cavity. The locking plate 304 is rotated so that the opening of the above-mentioned cavity faces the unified plate 7, and then the sliding rod 303 is slid to drive the main plate 401 to slide close to the unified plate 7, and the unified rod 8 is inserted into the insertion hole 404, so that the unified plate 7 covers the opening of the cavity. Figure 4 and Fig. 9As shown, the possibility of loss of the limiting rod 409 and the shovel head plate 405 is reduced, and the unified rod 8 is a magnet, the main board 401, the auxiliary board 403 and the hinged board 402 are made of steel, and the possibility of separation of the unified board 7 and the main board 401 is further reduced through magnetic adsorption, thereby increasing the practicality of the device;

[0055] When the device is in use, the engaging plate 304 and the sliding rod 303 are rotated and slid, so that the main plate 401, the auxiliary plate 403 and the hinged plate 402 move to the outside of the extension rod 302, and the shovel head plate 405 and the limiting rod 409 are taken out of the cavity, and then the auxiliary plate 403 and the hinged plate 402 are rotated, and the shovel head plate 405 is installed, so that the device can be used as a shovel. When it is necessary to store it, the main plate 401, the hinged plate 402 and the auxiliary plate 403 are rotated to form a cavity, and the shovel head plate 405 and the limiting rod 409 are stored, so that when the entire shovel plate 4 is idle, the space occupied is further reduced, and it is further convenient to accommodate and carry the device;

[0056] Moreover, when in use, the main plate 401, the auxiliary plate 403 and the hinged plate 402 can not only be used as a part of the shovel, but also can be used as a container, thereby increasing the practicality of the three.

[0057] like Figure 2 , Fig.11 and Fig.12 As shown, in the second embodiment, the unified plate 7 is rotatably mounted on the extension rod 302, and a receiving cavity 9 is provided on the tail rod 3, and a support rod 10 is movably mounted in the receiving cavity 9, and a limiting block 11 is installed at one end of the support rod 10 located in the receiving cavity 9, and an external thread is provided on the limiting block 11, and an internal thread is provided in the receiving cavity 9. The support rod 10 is a hollow structure, and a resistance rod 12 is movably mounted in the support rod 10, and a limiting block 11 is also installed at one end of the resistance rod 12 located inside the support rod 10, and an internal thread is also provided in the inner cavity of the support rod 10. The resistance rod 12 is used to resist the inner wall of the through groove 602 on the tail rod 3, and the support rod 10 is installed on the end of the tail rod 3 where the threaded block 501 is not installed. At the end, the support rod 10 can rotate and slide in the accommodating chamber 9, and the interference rod 12 can rotate and slide in the support rod 10. When the device needs to use a shovel, first rotate the entire extension rod 302 to rotate it to the side facing the support rod 10. At this time, the projection of the support rod 10 is located in the through groove 602, and then slide the support rod 10 outward. When it slides to the limit block 11 and contacts the thread of the inner wall of the accommodating chamber 9, rotate the support rod 10. The rotation of the support rod 10 is restricted by the cooperation of the thread, and then slide the interference rod 12. When the limit block 11 slides to contact the thread on the inner wall of the support rod 10, rotate the interference rod 12 to restrict the sliding of the interference rod 12 through the thread. Figure 2As shown, the extension rod 302 is resisted by the resisting rod 12, so as to provide a supporting effect for the shovel board 4 when in use, thereby further increasing the stability of the shovel board 4 when in use.

[0058] like Figure 5 and Figure 7 As shown, in the second embodiment, a fixed rod 101 is installed on the first rod 1, a static cutting plate 201 is installed on the fixed rod 101, a curved plate 102 is installed on the fixed rod 101, a prying plate 103 is hinged on the fixed rod 101 through a torsion spring 104, a curved plate 102 is also installed on the prying plate 103, a pressure rod 105 for resisting the prying plate 103 is installed on the movable rod 202, the two curved plates 102 are located on the same side of the static cutting plate 201, and a cavity is provided between the curved plate 102 fixedly installed on the fixed rod 101 and the static cutting plate 201, the torsion spring 104 makes the prying plate 103 in a tilted state under normal conditions, so that the two curved plates 102 remain away from each other. When in use, when it is necessary When branches need to be cut, the device is extended into the branch cluster so that the opening of the cavity between the static cutting plate 201 and the arc plate 102 can accommodate the branches, and then the movable rod 202 is driven manually or by sliding the driving rod 6, so that the pressure rod 105 on the movable rod 202 presses the prying plate 103, so that the prying plate 103 rotates, so that the arc plate 102 located on the prying plate 103 is close to another arc plate 102, and when the dynamic cutting plate 203 and the static cutting plate 201 have completed cutting the branches, the branches are clamped by the proximity of the arc plates 102, which reduces the possibility of the branches falling into the branch cluster and being difficult to find after cutting, thereby further increasing the practicality of the device.

[0059] like Fig.13 As shown, in the second embodiment, a sandwich 13 is provided on the fixed rod 101, and a saw blade 14 is slidably installed in the sandwich 13 through a reset spring 26. The saw blade 14 is constructed with an inclined surface, and a push rod 15 for resisting the inclined surface of the saw blade 14 is slidably installed on the fixed rod 101. A screw block 16 that cooperates with the thread of the fixed rod 101 is rotatably installed on the free end of the push rod 15. In normal state, the reset spring 26 pulls the saw blade 14 to be located in the sandwich 13, reducing the possibility of inconvenience to the operator during the installation of the device. When the static cutting plate 201 and the dynamic cutting plate 203 are shearing, they are suitable for relatively small branches. When it is necessary to collect samples from relatively thick branches, the push rod 15 is slid to make it contact the inclined surface of the saw blade 14, so that the saw blade 14 moves to the outside of the interlayer 13, and then the screw block 16 is turned to be threadedly connected with the fixed rod 101 to limit the sliding of the push rod 15. Since the thicker branches are sawed by the saw blade 14, the thick branches themselves have enough holding force and will not slide with the sliding of the saw blade 14, thereby increasing the feasibility of the device. The saw blade 14 can be used to collect samples from relatively thick branches, further increasing the practicality of the device.

[0060] Embodiment 3

[0061] like Figure 1 - Fig.13 As shown, the third embodiment is further disclosed on the basis of the second embodiment. In the third embodiment, there are two saw blades 14, and the saw blades 14 are slidably matched with each other. The reset spring 26 is installed on one of the saw blades 14, and the other saw blade 14 is installed with a pull rope 17. A push spring 18 is installed between the saw blade 14 installed with the pull rope 17 and the first rod 1. The interlayer 13 is provided with an opening on one side of the saw blade 14 installed with the pull rope 17, so that the movement degree of the saw blade 14 is greater than that of the other saw blade 14. When in use, the saw blade 14 is set up When the saw blade 14 is placed on the branch, the pulling rope 17 is pulled, and the saw blade 14 is pushed and reset by the pushing spring 18, so that the saw blade 14 can slide back and forth on the branch. Through the above arrangement, when the saw blade 14 is placed on the branch, the pulling rope 17 is first pulled so that the saw blade 14 can be initially stuck in the branch, and a groove is sawed on the branch to facilitate sawing, and then the whole device is pulled to saw the branch. There is no need to drag the whole device at the beginning, which saves the operator's physical strength and enables the saw blade 14 to better saw the branch.

[0062] In the third embodiment, a connecting plate 20 is installed on the first rod 1, and an even number of pulleys 21 for winding the pulling rope 17 are rotatably installed on the connecting plate 20, and a pull ring 19 is installed on the free end of the pulling rope 17. When in use, the pulling rope 17 is wound by the pulley 21, so that the pulling rope 17 can be tightened by the pulley 21, so that when the pulling rope 17 is pulled, the saw blade 14 can be directly pulled, thereby reducing the possibility of a void when the pulling rope 17 is pulled, resulting in the need to pull a longer section of the pulling rope 17 to make the saw blade 14 slide, thereby improving the sensitivity of the device, and when the pulling rope 17 is pulled, by pulling the pull ring 19, the possibility of the pulling rope 17 causing marks on the user's hands during use is reduced.

[0063] In the third embodiment, a sliding plate 22 is slidably installed on the extension rod 5 and the tail rod 3, and a pulling rod 23 for being inserted into the pull ring 19 is installed on the sliding plate 22. Circular plates are installed on both sides of the pull ring 19, and the diameter of the circular plates is larger than the diameter of the pull ring 19. When in use, the pull ring 19 is sleeved on the pulling rod 23. At this time, the pulling rope 17 can be pulled by sliding the sliding plate 22. The sliding plate 22 is provided on the extension rod 5 and the tail rod 3. When in use, even after the length of the device is adjusted, the connection between the pull ring 19 and the pulling rod 23 can be met, which is convenient for pulling the pulling rope 17. When the length of the device is shortened due to reducing the extension rod 5, the pull rope 17 is wound up by rotating the pull ring 19, and then inserted into the pulling rod 23, which reduces the possibility of the pulling rope 17 being too long and further increases the practicality of the device.

[0064] In the third embodiment, a limiting plate 24 is installed at the end of the tail rod 3, and the length of the limiting plate 24 is greater than the inner diameter of the extension sleeve 301. When the extension sleeve 301 slides to the limiting plate 24, the limiting plate 24 blocks the extension sleeve 301, so that the extension sleeve 301 will not be separated from the tail rod 3 when sliding;

[0065] The end of the resistance rod 12 is hinged with a shaped plate 25, which is used to resist the limiting plate 24 to limit the sliding of the support rod 10 and the resistance rod 12. A rubber sheet is installed in the middle of the shaped plate 25. When in use, after the support rod 10 and the resistance rod 12 are stored, the shaped plate 25 is rotated so that the inner cavity of the shaped plate 25 accommodates and resists the limiting plate 24. Figure 3 As shown, the sliding of the support rod 10 and the abutment rod 12 is restricted, thereby reducing the space occupancy of the device and further increasing the practicality of the device.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
