Soil humidity data acquisition equipment

Abstract

The invention relates to the field of soil environment monitoring, and discloses soil humidity data acquisition equipment which comprises a humidity sensor shell, a screw rod arranged along the axis of the shell, a sleeve plate screwed to the periphery of the screw rod, a limiting mechanism enabling the sleeve plate to reciprocate in the axial direction of the screw rod, a plurality of traction rods having upper ends connected with the sleeve plate, and a drill bit hollow inside. The telescopic mechanism is arranged between the screw and the drill bit, the upper end of the rotating rod extendsout of the upper end of the screw, an outer gear structure is arranged on the periphery of the part, extending into the drill bit, of the rotating rod, an inner gear structure is arranged on the inner circumferential wall of the gear and meshed with the outer gear structure, and the rack is meshed with outer teeth of the gear. One end of the rack is fixedly connected to a humidity sensor. According to the soil humidity data acquisition equipment provided by the invention, the drill bit rotates and moves downwards, so that the situation that the probe of the humidity sensor directly collides with a hard object in soil is avoided, the probe of the humidity sensor is prevented from being damaged, and the measurement precision is ensured.

Description

technical field [0001] The invention relates to the field of soil environment monitoring, in particular to a soil moisture data acquisition device. Background technique [0002] Different environmental factors have a direct or indirect impact on the growth, development, reproduction and distribution of plants. Soil moisture is one of the important environmental factors. Suitable soil moisture is the basic condition for plant growth. In order to understand the status of soil moisture and ensure the healthy growth of plants , It is necessary to carry out periodic sampling surveys and tests on the moisture in the soil. [0003] In the investigation of environmental conditions, it is often necessary to use a humidity sensor to detect the humidity in the soil. When using a humidity sensor to detect the humidity in the soil, the humidity sensor is directly drilled into the soil to a certain depth for detection. However, since the soil is often mixed with hard objects such as grav...

[0003]In the investigation of environmental conditions, it is often necessary to use a humidity sensor to detect the humidity in the soil. When using a humidity sensor to detect the humidity in the soil, it is always The humidity sensor is directly drilled into the soil to a certain depth for detection, but since the soil is often mixed with hard objects such as gravel and glass, during the process of the sensor drilling into the soil, the probe at the front end of the humidity sensor is likely to directly contact with the soil. The collision of hard objects in the soil will cause damage to the humidity sensor probe and affect the detection accuracy
