The device comprises a handle I, a handle II, a handle III, a pressure rod I, a spring button I, a sleeve I, a pressure rod II, a spring button II, a sleeve II, an outer barrel, a groove IV, a support device, a pin I, an inclined rod, a pin II, a bolt I, a nut I, a soil sampler I, a soil breaker, a steady rest, an outer cover, a bolt II, a nut II, a soil sampler II, a sleeve III, a sliding rail I, a groove I, a groove II, a groove III, a baffle plate I, a sleeve IV, a sliding rail II, a tapered end, an annular ring I, a controller, a control button, a baffle plate II, a stepping motor, a motor box, a center shaft, a connecting shaft I, a gear, a rack, a wall clip I, a wall clip II, a connecting shaft II, a base plate, a triangular support, a straight rod, a groove V, a bolt III, a nut III, an annular ring II, an annular ring III, a switch I, a switch II, a switch III, a pressure rod III, a sleeve V, a total button, a forward start button, a reverse start button and a baffle plate III. The device can realize soil sampling operation in the vertical direction and the horizontal direction as well, and the effect of disturbance for undisturbed soil in the soil sampling process is little, so that semi-automation can be realized.

Description

technical field [0001] The invention relates to an undisturbed earth-taking device capable of obtaining vertical and horizontal directions simultaneously, belonging to the field of agricultural machinery. Background technique [0002] The research on soil physical and chemical properties (such as soil water, fertilizer, salt and heavy metals, etc.) plays a very important role in exploring the influence of the soil environment on plant growth. How to obtain the relevant data of the undisturbed soil is the key to this research. During the process, the original soil structure will be destroyed due to compaction of the original soil, so that the relevant soil parameters obtained are inconsistent with the actual situation, and even have large deviations, which largely hinders the success of a series of soil-related experiments. Carrying out, especially conventional undisturbed soil borrowing method adopts excavation profile method mostly, although this method can realize undistur...

Problems solved by technology

[0003] At present, in order to make the measured soil sample data more accurate, it is mainly realized through undisturbed soil fetches, such as a utility model patent for undisturbed soil fetches (201320308632.5), a shallow undisturbed soil fetcher (201320488119.9), a Soil implements (201320204521.x), the first two types of soil extractors realize soil entry and excavation operations manually, and the latter are driven by electro-hydraulic push rods to achieve soil extraction operations, and all three types of soil extractors can achieve soil extraction operations in shallow soil , the disturbing effect on the undisturbed soil during the soil extraction process is relatively small, and the soil samples obtained are closer to the undisturbed soil. It can only take soil in the vertical direction; a patent for an undisturbed soil taking device and its collection method (201310594332.2), the soil taking device can achieve the purpose of soil sampling at different depths, the operation method is relatively simple, but it cannot collect horizontal Undisturbed soil with different profiles

Invention patent for a deep soil soil fetcher (201210577269.7) realizes the purpose of deep soil sampling, and is easy to operate, but it is driven by a pedal pressure rod to realize soil entry and excavation operations. The operation of this device is relatively time-consuming and laborious and can only be realized take soil vertically

Invention patent for an undisturbed soil fetcher for sliding belt soil (201310323843.0), which can achieve the purpose of sampling undisturbed soil for sliding belts, and is suitable for drilling and retrieving soil horizontally and vertically. The power input is completed by manipulating the symmetrical handle, and the operation is relatively simple. The disturbance to the undisturbed soil is small, because it is completed by manpower, the operation speed is relatively slow, especially the device cannot obtain the undisturbed soil samples in the vertical and horizontal directions at the same time, in addition, when the device obtains the undisturbed soil samples in the horizontal direction, it also needs Manual excavation of the soil profile is labor-intensive, time-consuming and labor-intensive
