Sampling tool for soil information of saline-alkali soil

Abstract

The invention relates to the technical field of sampling, in particular to a saline-alkali soil information sampling tool which comprises a bearing plate, supporting legs are arranged on the bearing plate, a limiting block is fixedly connected to the outer side of the bearing plate, a self-taking assembly for sampling is arranged on the bearing plate, and a starting rod and a main sending block are arranged in the self-taking assembly. Power can be provided for saline-alkali soil sampling through cooperation of a starting rod and a main sending block, through cooperation of a self-taking assembly, a cut-off assembly and a self-repairing assembly, when saline-alkali soil needs to be sampled, a transmission column rotates to drive the main sending rod to promote downward pressing of the starting rod, and downward pressing of the starting rod drives vertical sampling of a sampling shell; the situation that the sampling quality and the data reliability are affected due to the fact that soil particles are rearranged and even crushed into aggregate structures due to left-right shaking in the sampling process is avoided, and the accuracy of saline-alkali soil sampling information is improved.
