It can be seen that the utility model provides a mud appearance collector is applicable to the sediment sample collection in river course, simple structure, convenient operation, and can effectually keep the river course not changed by the layering physical form of the sediment of gathering for operating personnel can be succinct more, conveniently gather complete and have obvious layered structure's column river sediment mud appearance, carry out the analysis of characteristics such as mud appearance colour, smell and mobility, thereby improve the scientific of research and the accuracy of observation data. In addition, when the mud sample collector is used, an operator can complete the collection work of the bottom mud of the river channel by shoreside at a representative river section or by means of a bridge without a drilling device and a ship. It should be noted that, the specific structure of the check valve 300 is not limited in the present invention; the length of extension pipe can be adjusted, through the adjustment the sediment sample of the different degree of depth can be gathered to the length of extension pipe to adapt to the sampling work in various regions, improved the operating efficiency in the very big degree, reduced the running cost.

Preferably, the sampling tube 100 is provided with a bevel 110 at one end for inserting into the sediment for sampling. Thereby, the insertion of the sampling tube 100 into the substrate sludge for sampling is facilitated by the chamfered opening 110.

Preferably, the extension pipe includes a plurality of extension single pipes 210 detachably connected. Therefore, the whole length of the extension pipe can be adjusted through the arrangement, and then sediment samples of different depths can be collected through adjusting the number of the extension single pipe 210, so that the sampling device is suitable for sampling work of various regions, the working efficiency is improved to a great extent, and the working cost is reduced.
