Embodiment

[0032] See Figure 5 In this embodiment, tilt detection is performed, and the detection method is as follows:

[0033] Hold the handle 3, put the cone structure 10-2 perpendicular to the ground, and push the handle 3 downward so that the silicone block 12 on the cross bar 6 is clamped in the clamping slot 4-2 at the upper edge of the strip groove 4-1 At this time, the detection end 8 is placed in the insertion hole 10-3, and the handle 3 is continued to be pushed down. While pushing, rotate the handle 3, driving the detection rod 4 to rotate, and driving the excavating mechanism 5 to rotate, digging The soil mechanism 5 excavates the soil downward under the action of the cone structure 10-2 and the threaded notch 10-1. During the opening process, the detection rod 4 and the detection end 8 connected to its lower end enter the soil together In the layer

[0034] When the cone 10-2 reaches below the soil layer that needs to be detected, the handle 3 stops rotating. At this time, the...

Abstract

The invention discloses a soil moisture measuring method and measuring equipment. The invention relates to the technical field of soil detection. Two cross rods are symmetrically arranged outside thedetection rod; one end of the cross rod is movably clamped in a strip-shaped groove formed in the annular wall of the detection rod up and down; the other end of the cross rod is fixed at the upper end of the connecting rod, the lower end of the connecting rod is fixed on the top wall of the screw rod, an imbedding hole is clamped in the screw rod, the detection end is movably arranged in the imbedding hole, a threaded notch is formed in the outer ring wall of the screw rod, and the lower end of the screw rod is of a conical head structure; and the outer diameter of the screw rod is greater than that of the detection rod. The detection rod can be inserted while digging soil, the problem that the detection rod is damaged by hard objects such as gravels in the soil in the insertion process is avoided, the detection rod is effectively protected, and meanwhile the detection time and the detection procedure can be saved.

Description

Technical field [0001] The invention relates to the technical field of soil detection, in particular to a soil moisture measurement method and measurement equipment. Background technique [0002] Soil water is the main source of water absorption by plants (except for hydroponic plants). In addition, plants can also directly absorb a small amount of water that falls on the leaves. The main sources of soil water are precipitation and irrigation water, which participate in the large water cycle of lithosphere-biosphere-atmosphere-sphere-hydrosphere. [0003] At present, the soil moisture measurement equipment is to insert a probe rod of suitable length into the soil. However, due to the presence of hard objects such as sand and gravel in the soil, it is easy to damage the probe during the insertion process. The existing technology adopts the method of first digging the soil and then inserting the rod, which increases the operation procedures and the inspection time, and urgent impro...
