Embodiment 1

[0021] Embodiment 1, portable semi-automatic rotary type soil original state sampler, with reference to figure 1 :

[0022] Portable semi-automatic rotary soil sampler, level meter 2 and rotating power device 5 fixed on the hollow T-shaped structure base 1 of the longitudinal axis, rechargeable battery as the power source, and the down-cutting speed is controlled by the non-concentric shaft transmission mechanism 4 and the reduction mechanism 6 , the non-concentric shaft transmission mechanism 4 is connected to the hollow drill bit 8 with the function of undercutting through the buckle 7 . A mobile ruler 3 for measuring the depth of the soil sample is installed through the hollow axis of the matrix. A sampling tube 9 installed on the base body is built into the hollow drill bit, and the sampling tube does not perform rotary motion when working. When the sampler is working, the hollow drill bit is rotated by the transmission output end of the reduction mechanism so that the s...

Abstract

The disclosed sampler includes following structure: sampling tube is fixed on T shape structured basal body with hollow vertical axis; rotating power set is installed on the basal body; through drive gear with not coaxial shaft, the rotating power set is coupled to hollow boring bit; diameter of the hollow boring bit is larger than diameter of the sampling tube; and being coaxial to the sampling tube, the hollow boring bit is positioned outside the sampling tube. Optimized scheme includes following parts: reduction gears is setup between the rotating power set and the hollow boring bit; rechargeable battery is as power for the rotating power set; level meter is setup on table-board of T shape structured basal body; shiftable rule is provided for measuring height of the soil sample. Advantages are: lowering interference on soil to minimum, saving time and labor, portable and semi automatic operation.

Description

technical field [0001] The invention belongs to a soil sampling tool, in particular to a hand-held semi-automatic rotary soil undisturbed sampler, which is especially suitable for undisturbed soil sampling of farmland plow layer and sub-plow layer. Background technique [0002] Soil science research and related work require that the collection of soil samples must be representative, otherwise, the obtained analytical data will lose their application value. Wrong sampling may lead to completely wrong conclusions, even though the specific analysis operation may be very standardized and precise. Therefore, in this sense, sampling technique is the key to soil research. The standard sampling method is that the soil sampling depth and weight of each sampling point (mainly controlled by capacity when sampling in the field) should be uniform, and the proportion of the upper layer and the lower layer of the soil sample should also be the same. The basic requirement for collecting u...
