[0022] (III) Beneficial effects

[0023] Compared with the prior art, the present invention provides an intertidal benthic animal stratified sampler, which has the following beneficial effects:

[0024] 1. Through the inner rotating groove, the limit baffle, the end guide groove and the locking bolt arranged on the edge of the collection vertical cylinder, it is convenient to block and unblock the collection groove by rotating the position of the limit baffle, so as to facilitate the entry of samples during sampling and to be able to sample when the collection vertical cylinder reaches the predetermined collection depth during drilling. At the same time, the limit sliding groove arranged on the top of the mounting round plate and the limit block at the bottom of the sampling box to be pushed out facilitate the limit sliding of the sampling box to be pushed out;

[0025] At the same time, the pushing mechanism composed of the connecting rod, the mounting sleeve, the rotating support, the drive shaft and the first motor is used so that after the collection trough reaches the sampling depth, the pushing mechanism is used to push the sampling box to move, so that the sampling box is pushed out of the collection trough. Combined with the accommodating cavity and the collection scraper, the collected samples are conveniently scraped into the sampling box, so as to achieve better collection of samples at this level.

[0026] 2. By arranging a support spring and a mounting block on the inner side of the mounting sleeve, an elastic support connection structure is formed between the mounting sleeve and the connecting rod, so that the mounting sleeve and the connecting rod can make the pushed-out sampling box fit more tightly in the intertidal mud layer when pushing the sampling box to collect samples, thereby achieving more effective sampling. In combination with the movable shaft, the movable extrusion block and the second motor, it is convenient to squeeze and drive the pushed-out sampling box to move back and forth through the rotation of the movable extrusion block. When the position of the mounting sleeve is limited, the reciprocating expansion and contraction of the support spring can be used to make the pushed-out sampling box shake continuously, thereby facilitating the vibration separation of the soil and benthic animals in the collected sample. At the same time, when the sample is collected subsequently, it is convenient to quickly separate the sample from the pushed-out sampling box through vibration, thereby improving the convenience of collection.

[0027] 3. The mounting plate, connecting screw, third motor and sliding seat facilitate the movement of the disassembly and assembly card seat, connecting frame and profile plate, thereby facilitating the alignment collection box to gradually approach or move away from the collection vertical cylinder. By aligning the collection box and the extruded rubber strips on its edges with the edges of the collection vertical cylinder, the samples pushed out of the sampling box by vibration can be effectively collected. The fitting grooves and closing plates provided on the edges of the alignment collection box can seal the edges of the alignment collection box, thereby facilitating the collection and preservation of samples.

[0028] The disassembly and assembly card holder and the connecting frame are connected by a snap connection, and the limit pin facilitates the limiting of the distance between them, so that the connecting frame and the molded plate are more convenient to disassemble, and the alignment collection box is convenient to disassemble, making it more convenient to carry and transport samples.

[0029] 4. The installation of the driving hydraulic cylinder is facilitated by the cross frame, support plate and horizontal plate, and the sampler can be adjusted and supported by the multi-stage telescopic rod and limit anchor head to ensure stability during the sampling process. At the same time, the connecting frame, drive motor, rotating arc block and limit rail are used to conveniently drive the connecting sleeve and the collection vertical cylinder to rotate, so as to facilitate drilling into the intertidal zone for sampling. With the cone head and spiral blade, the collection vertical cylinder can more conveniently rotate the soil and benthic animals into the collection trough when rotating for drilling and sampling, making sampling more convenient and simplifying the operation during sampling.

The bottom end of the sliding seat 39 is connected to a disassembly and assembly base 40.

[0046] Inside the dismountable card seat 40, a connecting frame 42 is fitted and connected. At the position corresponding to the collection groove 15 on the edge of the connecting frame 42, a U-shaped plate 43 is installed. Inside the dismountable card seat 40, a card slot is opened. The top of the connecting frame 42 is clamped in the card slot, and the connecting frame 42 and the dismountable card seat 40 are detachably connected by a limit pin 41, making it more convenient to disassemble the connecting frame 42 and the U-shaped plate 43, facilitating the disassembly of the alignment collection box 44. The inside of the U-shaped plate 43 is embedded and clamped with an alignment collection box 44. The position of the alignment collection box 44 corresponds to the position of the collection groove 15, and the end area of the alignment collection box 44 is larger than the area of the collection groove 15, facilitating the effective collection of samples by the alignment collection box 44;

[0047] On one side edge of the alignment collection box 44, a fitting groove 45 is opened. Inside the fitting groove 45, a closing plate 46 is fitted and clamped. At the edge end of the alignment collection box 44, an extrusion rubber strip 47 is provided. At the edge end of the alignment collection box 44, an arc groove is provided, and this arc groove fits with the edge of the collection vertical cylinder 12. The extrusion rubber strip 47 is bonded to the edge of the arc groove. By the alignment collection box 44 and the extrusion rubber strip 47 on its edge fitting with the edge of the collection vertical cylinder 12, it is convenient to effectively collect the samples pushed out through vibration in the push-out sampling box 22.

[0048] The working principle and usage process of the present invention: First, through the cross frame 1, the support plate 2, and the horizontal plate 3, it is convenient to install the driving hydraulic cylinder 4, and in cooperation with the multi-stage telescopic rod 5 and the limit anchor head 6, it is convenient to adjust and support the sampler, ensuring the stability during the sampling process. Using the rotating bracket 7, the driving motor 8, the rotating arc block 9, and the limit rail 10, it is convenient to drive the connecting sleeve 11 and the collection vertical cylinder 12 to rotate. The driving hydraulic cylinder 4 is convenient to drive the collection vertical cylinder 12 to perform lifting activities, so as to facilitate drilling into the intertidal zone for sampling. In cooperation with the cone head 13 and the spiral leaf 14 on the edge of the collection vertical cylinder 12, when the collection vertical cylinder 12 rotates and drills for sampling, it can more conveniently make the soil and benthic animals rotate into the collection groove 15, making the sampling more convenient and simplifying the operation during sampling; [[ID=X]]

[0049] During sampling, through the inner rotating groove 16, the limit baffle 17, the end guide groove 18, and the locking bolt 19 provided on the edge of the collection vertical cylinder 12, it is convenient to block and unblock the collection groove 15 by rotating the position of the limit baffle 17, facilitating the entry of samples during sampling and enabling sampling when the collection vertical cylinder 12 reaches the predetermined collection depth during drilling. At the same time, through the limit sliding groove 21 provided on the top of the mounting circular plate 20 and the limit block 23 at the bottom of the push-out sampling box 22, it is convenient for the limit sliding of the push-out sampling box 22;

[0050] When the sampling box 22 is pushed out of the edge of the collection vertical cylinder 12, the pushing mechanism composed of the connecting rod 26, the mounting sleeve 27, the rotating support 28, the driving shaft 29 and the first motor 34 is used to make the collection trough 15 reach the sampling depth. The pushing mechanism is used to push the sampling box 22 to move, so that the sampling box 22 is pushed out of the collection trough 15. Combined with the accommodating cavity 24 and the collection scraper 25, it is convenient to scrape the collected samples into the sampling box 22, so as to better collect the samples at this layer. At the same time, by arranging a supporting spring 30 and a mounting block 31 on the inner side of the mounting sleeve 27, an elastic support connection structure is formed between the mounting sleeve 27 and the connecting rod 26. Therefore, when the mounting sleeve 27 and the connecting rod 26 push the sampling box 22 to collect samples, the sampling box 22 can be more closely fitted in the intertidal mud layer, thereby achieving more effective sampling.

[0051] When it is necessary to collect the samples collected in the sampling box 22, the mounting plate 36, the connecting screw 37, the third motor 38 and the sliding seat 39 are used to conveniently drive the disassembly and assembly card seat 40, the connecting frame 42 and the shaped plate 43 to move, so as to facilitate driving the alignment collection box 44 to gradually approach the collection vertical cylinder 12. By aligning the collection box 44 and the extruded rubber strip 47 on its edge with the edge of the collection vertical cylinder 12, the samples pushed out by vibration in the sampling box 22 can be effectively collected. At the same time, the support spring inside the mounting sleeve 27 and the connecting rod 26 is On the basis of the support frame 30 and the mounting block 31, the movable shaft 32, the movable extrusion block 33 and the second motor 35 are coordinated to facilitate the extrusion drive of the push-out sampling box 22 to reciprocate by the rotation of the movable extrusion block 33. When the position of the mounting sleeve 27 is limited, the reciprocating expansion and contraction of the support spring 30 is utilized to make the push-out sampling box 22 shake continuously, thereby facilitating the vibration separation of the soil and benthic animals in the collected sample. At the same time, when the sample is subsequently collected, the sample can be quickly separated from the push-out sampling box 22 by vibration, thereby improving the convenience of collection.

[0052] Finally, the disassembly and assembly card holder 40 and the connecting frame 42 are connected by a snap connection, and the limit pin 41 facilitates limiting the position between them, so that the connecting frame 42 and the shaped plate 43 are more convenient to disassemble, and the alignment collection box 44 is convenient to disassemble, making it more convenient to carry and transport samples. The fitting groove 45 and the closing plate 46 set on the edge of the alignment collection box 44 can block the edge of the alignment collection box 44, thereby facilitating the collection and preservation of samples.

[0053] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
