Description

Technical Field

[0001] The utility model relates to the technical field of corn root sampling, in particular to a corn root sampling device. Background Art

[0002] The crop corn is used as the research object, and the corn root system is semi-automatically collected to measure the root activity, nitrogen, phosphorus and potassium content and other physiological and biochemical indicators. After or before the crop matures, its root system is mechanically collected, and the corn root system is dug out under the greatest possible conditions and the impact on the soil layer is minimized, so that the soil living environment of the subsequent planted plants is basically the same as before digging, to ensure the implementation of the entire experimental system.

[0003] Patent CN111397946B proposes a corn root sampling device, which controls the swinging part through a driving mechanism to adjust the angle of the shovel. The driving mechanism controls the telescopic pressing part to allow the shovel to enter the soil. This not only ensures the angle of the shovel entering the soil, but also ensures the depth of the shovel entering the soil, thereby ensuring the excavation of the corn roots. At the same time, a spray mechanism can be used to clean the corn roots and sample the corn roots.

[0004] In the above scheme, four sets of triangular iron shovels are inserted into the soil, and the corn roots are taken out together with the surrounding soil after closing. However, this technical method is not convenient for adjusting the insertion position of the iron shovel, and cannot be adjusted according to the range of the corn. In addition, when the iron shovel is inserted and rotated inward, the surrounding soil layer will be squeezed, which is easy to damage the environment and structure of the surrounding soil.

The four groups of plug plates are vertically inserted into the soil through the first electric push rod. Different lengths can be inserted according to the depth of the root system. Then the reciprocating numerical movement is performed to loosen the soil in the insertion area. In conjunction with the rotation of the second rotating plate, the soil in the circular range within the corn root planting area is loosened, thereby facilitating its removal. The structural damage to the surrounding soil layer is relatively small, which is also convenient for the return planting of the corn roots in the later stage.
