Abstract
Description
Technical Field
[0001] This utility model relates to the field of marine product testing, and in particular to a sandworm sampling device. Background Technology
[0002] In the process of marine biological research, it is sometimes necessary to take slicing samples from marine organisms, such as sandworms. In the traditional slicing process, because the surface of sandworms is covered with mucus, making it moist and smooth, and they will move violently, especially when stimulated by external factors, it is necessary to spray alcohol on the surface of the sandworms to anesthetize them before slicing.
[0003] When spraying alcohol, it is desirable for the sandworm to be in an extended state; otherwise, the anesthesia effect will be affected. The traditional method is for one operator (wearing gloves) to hold both ends of the sandworm, straightening it and keeping it in an extended state, while another operator sprays alcohol onto the surface of the sandworm. This method requires two people to operate, consuming more manpower, and the work efficiency is relatively low.
[0004] Therefore, a method or apparatus is needed to solve the above problems. Utility Model Content

[0027] An intake pipe 20 is connected to the second pipe 15 between the second one-way valve 32 and the piston 17. The port of the intake pipe 20 is open to the atmosphere, and a third one-way valve 21 is also provided in the intake pipe 20, through which air can enter the second pipe 15.
[0028] The two side walls of the housing 1 are respectively provided with operation holes 22, and the operation holes 22 are corresponding to the two ends of the positioning groove 8.
[0029] One end of the housing 1 is also provided with a tool support beam 23. The middle part of the tool support beam 23 is movably supported by a tool connecting shaft 24. The bottom end of the tool connecting shaft 24 is connected to a cutter 25 located below the tool support beam 23. A second spring 26 is sleeved on the tool connecting shaft 24. The second spring 26 is located between the tool support beam 23 and a limiting block 27 located at the end of the tool connecting shaft 24.
[0030] The housing 1 is also equipped with an alcohol pipeline that communicates with the second interlayer 12, and the top opening of the alcohol pipeline is higher than the height of the alcohol nozzle 9.
[0031] The gripper 7 includes a left gripper arm 28 and a right gripper arm 29 that are hinged to each other. A torsion spring 30 is provided at the connection between the two, and an arc-shaped clamping part 31 is provided at the bottom end of both the left gripper arm 28 and the right gripper arm 29.
[0032] The bottom opening of the first pipe 13 is located at the bottom of the second interlayer 12.
[0033] The working process of the sandworm sampling device in this utility model embodiment is as follows: First, adjust the relative position of the two clamping mechanisms on the box 1 according to the size of the sandworm to be sampled, that is, move the clamping mechanisms to a position that will not obstruct the placement of the sandworm, and then place the sandworm in the positioning groove 8.
[0034] Move the two clamping mechanisms to both ends of the sandworm, then use the clamping mechanisms to clamp both ends of the sandworm, and move the two clamping mechanisms in the opposite direction to stretch the sandworm to an extended state; then the operator presses the piston rod 16, and injects air into the second interlayer 12 through the piston 17. The second interlayer 12 is pre-filled with alcohol. After the air enters the closed second interlayer 12, under the action of air pressure, the alcohol enters the first interlayer 10 through the first pipe 13 and is sprayed out through the alcohol nozzle 9. Since there are multiple pairs of alcohol nozzles 9, and they are evenly distributed along the length of the positioning groove 8, the surface of the sandworm will be evenly sprayed with alcohol to achieve an anesthetic effect.
[0035] The position of the sandworm is adjusted by adjusting the specific position of the clamping mechanism. The sandworm is transported to the bottom of the cutter 25 (at this time, the end of the sandworm protrudes outside the box 1 through the operation hole 22). The operator quickly presses down the cutter connecting shaft 24, and the cutter 25 moves down to cut off the end of the sandworm. The cut-off part can then be transferred to the next process for further processing.
[0036] When it is necessary to control the movement of the clamping mechanism, simply push the support beam 3, and the slider 4 will slide within the slide rail 5;
[0037] When alcohol needs to be injected into the first interlayer 10 and the second interlayer 12, the seal at the top of the alcohol pipeline is opened, and alcohol is injected into the second interlayer 12 through the alcohol pipeline. After the alcohol pipeline is full, the injection stops and is resealed. When the piston rod 16 is pressed, under the action of the piston 17, the air in the second pipeline 15 is introduced into the second interlayer 12 through the second one-way valve 32. The air pressure in the second interlayer 12 increases, which drives the alcohol from the first pipeline 13 through the first one-way valve 14 into the first interlayer 10. When the piston rod 16 is released, under the action of the first spring 19, the piston rod 16 returns to its original position. During this process, outside air enters the second pipeline 15 through the air inlet pipeline 20 to replenish its internal cavity. During the above process, the first one-way valve 14, the second one-way valve 32 and the third one-way valve 21 can control the flow direction of the medium (alcohol or air).
[0038] After several repeated operations, alcohol can be seen spraying out through alcohol nozzle 9. Then, open the seal at the top of the alcohol pipeline and refill the second interlayer 12 with alcohol until the alcohol pipeline is full and then reseal it. From this step onwards, when the piston rod 16 is pressed again, alcohol will spray out from multiple alcohol nozzles 9 to anesthetize the sandworms located in the positioning groove 8.
[0039] When the gripper 7 needs to be operated to perform the gripping / opening action, the operator only needs to drive the top of the left gripper arm 28 and the right gripper arm 29 to move closer to each other. Under the action of the lever principle, the two arc-shaped gripping parts 31 at the bottom will move away from each other. After the left and right gripper arms are released, under the action of the torsion spring 30, the two arc-shaped gripping parts 31 move closer to each other and clamp the sandworm in the middle from both sides respectively.
[0040] During cutting and sampling, the operator quickly presses down the tool connecting shaft 24, and the cutter 25 moves downward to cut the sandworm below. During this process, the second spring 26 is compressed. After the operator releases the pressure, the tool connecting shaft 24 drives the cutter 25 back to the initial position under the action of the second spring 26, waiting for the next cutting and sampling operation.
