Description

Technical Field

[0001] The invention belongs to the technical field of specimen collection, and in particular relates to a harmless specimen collection device for higher emergent plants. Background Art

[0002] Emergent plants: plants whose roots and rhizomes grow in the bottom mud of the water, and whose stems and leaves emerge from the water. They are often found in shallow waters of 0-1.5 meters, and some species grow on wet shores. The part of these plants in the air has the characteristics of terrestrial plants, and the part growing in the water has the characteristics of aquatic plants. Common plants include reeds, cattails, water chestnuts, lotus, water celery, wild rice stem, lotus, cattail, etc.

[0003] In order to make specimens of emergent plants harmlessly, it is necessary to obtain the complete stems and leaves of the emergent plants. Taking the lotus as an example, its stem extends underwater. If it is pulled upwards directly, the stem may easily break. However, collecting it underwater has certain technical difficulties and risks. Summary of the invention

DETAILED DESCRIPTION

[0025] The present application is described in further detail below. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0026] Example 1

[0027] like Figure 1-4 As shown, a device for collecting harmless specimens of higher emergent plants comprises:

[0028] The collar 1 is provided with an opening, and a locking assembly is provided at the opening, and the locking assembly is used to prevent the collar 1 and the stem of the emergent plant from being separated;

[0029] Two cutting assemblies provided on the collar 1 are used to cut the stems of emergent plants;

[0030] Two stoppers 2 are arranged on the collar 1, and when the stoppers 2 contact the bottom of the water, they move relative to the cutting assembly so that the cutting assembly is triggered;

[0031] The connecting piece 3 provided on the thimble 1 is used for recovering the thimble 1 .

[0032] As a further solution of the present invention, the locking assembly includes a lock buckle 4, on which a first magnet 5 is provided, and on the ring 1, a second magnet 6 with opposite magnetic properties to the first magnet 5 is provided, so that during the rotation of the lock buckle 4, the first magnet 5 contacts the second magnet 6 and the opening of the ring 1 is blocked.

[0033] As a further solution of the present invention, the cutting components are symmetrically distributed on both sides of the ring 1, and the cutting components include a bracket 7, a No. 1 telescopic rod is provided on the bracket 7, a No. 1 telescopic rod is wound around the No. 1 telescopic rod, and a cutting blade 8 is connected to the end of the No. 1 telescopic rod away from the corresponding bracket 7, and a stop block 9 is provided on the cutting blade 8, and the stop block 9 is in contact with the limit member 2.

[0034] As a further solution of the present invention, a bend 10 is provided on the limiting member 2, and the bend 10 is staggered with the stopper 9 during movement so that the stopper 9 can move.

[0035] In the above embodiment, the user takes a boat to the collection site, puts the collar 1 on the stem of the plant to be collected, turns the lock 4, and uses the magnetic attraction between the No. 1 magnetic block 5 and the No. 2 magnetic block 6 to limit the lock 4, thereby preventing the plant stem from being separated from the collar 1. After the installation is completed, the collar 1 is placed in the water by holding the connecting piece 3. The collar 1 dives along the stem of the plant in the water under its own gravity until the collar 1 moves to the bottom of the water. When the limiting piece 2 on the collar 1 contacts the bottom of the water, the collar 1 continues to move downward, so that the limiting piece 2 and the collar 1 and the stopper 9 are relatively displaced. When the stopper 9 is no longer in contact with the limiting piece 2, the No. 1 spring drives the cutting blade 8 to move, cutting off the stem of the plant. The user uses the connecting piece 3 to pull the collar 1 out of the water and can also bring the plant up.

[0036] The bend 10 on the limiting member 2 can allow the stopper 9 to be smoothly separated from the limiting member 2, and the limiting member 2 can extend downward to trigger the cutting assembly.

[0037] As a further solution of the present invention, a connecting rope 16 is provided on the limiting member 2 .

[0038] In the above embodiment, if there are a lot of aquatic plants or a lot of silt on the bottom of the water, the limiter 2 cannot move relative to the cutting assembly. At this time, by quickly pulling the connecting rope 16, the limiter 2 can move quickly to trigger the cutting assembly. Because the collar 1 has a certain inertia and the water has resistance to the collar 1, the collar 1 is relatively stable during the movement of the limiter 2, ensuring the smooth movement of the limiter 2.

[0039] As a further solution of the present invention, two installation grooves are provided on the inner wall of the collar 1, a No. 2 telescopic rod is provided in the installation groove, a No. 2 telescopic rod is wound with a No. 2 spring, a clamping block 11 is provided at the telescopic end of the No. 2 telescopic rod, a No. 1 limit block 12 is provided on the clamping block 11, and a No. 2 limit block 13 corresponding to the No. 1 limit block 12 is provided on the cutting blade 8, and when the No. 2 limit block 13 moves, it drives the No. 1 limit block 12 to move.

[0040] As a further solution of the present invention, a sponge is provided on the inner wall of the clamping block 11 .

[0041] In the above embodiment, the cutting blade 8 drives the second stopper 13 to move when it moves, and when the second stopper 13 moves to the first stopper 12, it drives the first stopper 12 to move together, so that the clamping block 11 is driven synchronously. The two clamping blocks 11 clamp the stem of the plant through the sponge, so that the plant can be pulled out of the water together with the collar 1, avoiding the stem of the plant from hooking other plants and being unable to move upward, thereby ensuring the integrity of the plant.

[0042] As a further solution of the present invention, the limit member 2 is provided with a plurality of slots 14 along its length direction, the bracket 7 is provided with a saw blade 15, the saw blade 15 includes saw teeth, the saw teeth are engaged with the slots 14, and a reset spring is provided between the limit member 2 and the ring 1 to drive the limit member 2 to reset.

[0043] In the above embodiment, when the collar 1 moves upward, it hooks the roots of other plants, which will hinder the movement of the collar 1. By repeatedly pulling the connecting rope 16, the limiter 2 is caused to reciprocate up and down under the action of the reset spring, so that the saw blade 15 is continuously reversed and rotated. During the rotation process, the saw blade 15 vertically cuts off the roots hooked on the collar 1, so that the collar 1 can be smoothly pulled upward out of the water.

[0044] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
