[0038] Reference Figures 1 to 4 The tidal flat sediment sample collector of the first embodiment of the present application includes a support assembly 100, a drive assembly 200, a sample collection assembly 300 and a stabilization assembly 400.

[0039] The support assembly 100 includes a base plate 110; the drive assembly 200 is arranged on the support assembly 100; the sample collection assembly 300 includes a sampling barrel 310 and a sampling conveying component 320 arranged on the sampling barrel 310, the drive assembly 200 is connected to the sampling barrel 310 and is used to drive the sampling barrel 310 to move, the sampling barrel 310 is respectively provided with an opening 311 and a sampling port 312, the sampling conveying component 320 is respectively connected to the opening 311 and the sampling port 312 and is suitable for conveying samples; and the stabilization assembly 400 includes a through-plug 410 and an auxiliary support member 420, the through-plug 410 is arranged at the bottom of the base plate 110 and extends in a direction away from the base plate 110, the number of the auxiliary support members 420 is multiple, and each auxiliary support member 420 is arranged at intervals around the circumferential side wall of the base plate 110 to increase the support area of ​​the base plate 110.

[0040] It can be understood that the tidal flat sediment sample collector of the embodiment of the present application is used for sampling tidal flat sediments, and is specifically a portable tidal flat sediment sample collector that solves the problem that long-term manual sampling operation reduces sampling efficiency and has poor stability when the bottom material is silt with a relatively high water content. Among them, the tidal flat sediment sample collector is an overall portable design, and mechanical parts can be used to replace manual operation to sample the tidal flat, thereby reducing the operation intensity and improving the sampling efficiency.

[0041] In some embodiments, the drive assembly 200 can drive the sampling tube 310 to move, so that the opening 311 can extend into the mudflat, the sample enters from the opening 311, and is transported along the interior of the sampling tube 310 to the sampling port 312 through the sampling transmission component 320, so that samples can be collected quickly from deeper parts of the mudflat and the samples can be easily removed.

[0042] In some embodiments, the insertion member 410 may be a structure such as a pointed cone or an inserted cone that can be inserted into the mudflat, and the auxiliary support member 420 may be a structure such as a support plate or a support bar that can extend along the side of the bottom plate 110 and increase the contact area. By setting the insertion member 410 at the bottom of the bottom plate 110 and the auxiliary support member 420 set on the side of the bottom plate 110, the overall stability can be increased when the bottom is silt with a relatively high water content.

[0044] Reference Figures 1 to 4 The mudflat sediment sample collector of the first embodiment of the present application, when sampling mudflat sediments, inserts the insertion plug 410 into the mudflat, and increases the contact area between the bottom plate 110 and the mudflat through the auxiliary support member 420, thereby improving its stability during use, and drives the sampling tube 310 to be inserted into the mudflat through the driving assembly 200, and performs sampling operations on the fixed position of the mudflat through the sampling transmission component 320, thereby improving the sampling efficiency and sampling effect. In summary, the mudflat sediment sample collector can solve the problem of reduced sampling efficiency caused by large-scale and long-term manual sampling operations as much as possible, and also solves the problem of poor stability when the bottom material is silt with a relatively high water content as much as possible.

[0045] In some embodiments of the present application, reference Figure 2 and Figure 4 The sampling and conveying component 320 includes a first motor 321, a rotating shaft 322 and a sampling paddle 323.
