Embodiment Construction

[0030] The invention provides a device for detecting moisture in dry soil, which includes a cylindrical detection rod 1, the detection rod 1 is hollow inside, and is made of high-strength stainless steel. The conical cap includes a first conical cap 2 and a second conical cap 3 , and the first conical cap 2 and the second conical cap 3 are interchangeably mounted on the head of the detection rod 1 . Preferably, the inner wall of the head of the detection rod 1 is provided with an internally threaded hole, and one end of the conical cap connected to the detection rod 1 is provided with an externally threaded rod 11 cooperating with the internally threaded hole, and the two are threaded to facilitate replacement.

[0031] The first conical cap 2 is provided with a first hole group 21 . The size and shape of the two conical caps can be consistent. The first conical cap 2 is used for detection, and the second conical cap 3 is used as a tip when the detection rod is inserted into t...

Abstract

The invention discloses a device used for detecting moisture in dry soil. The device comprises a detection rod, conical caps, a leaf spring assembly, a detection assembly and a ball screw, wherein the conical caps comprise the first conical cap and the second conical cap, the leaf spring assembly comprises a movable plate and a spring, the detection assembly comprises a movable sleeve and a soil moisture sensor, the ball screw comprises a screw body and a screw nut, the screw nut is fixed into the detection rod, the screw body is used for driving the movable sleeve to move downwards when moving downwards, and the upper end of the screw body extends out of the detection rod. The two conical caps are arranged on the detection rod, and different conical caps are used during sampling and detection. During detection, a probe of the soil moisture sensor penetrates through a first hole group and then extends into soil through the ball screw, and accordingly moisture detection of the layer of soil can be achieved. After detection, the conical caps can be replaced so that the detection device can continue to extend into the lower layer of soil, and detection is conducted again.

Description

technical field [0001] The invention relates to the technical field of soil detection instruments, in particular to a device for detecting moisture in dry soil. Background technique [0002] The growth of plants requires a good soil environment. Different plants or the same plant have different requirements for the soil environment at different growth stages. By detecting changes in temperature, moisture content, and pH in the soil, it can help users understand the basic situation of the soil in a timely manner. Changes in the soil can determine whether the growth of plants in the soil urgently needs water and the addition of acid-base fertilizers. The timely acquisition of environmental temperature change information for plant growth can prevent the damage to plants caused by sudden cooling and warming of the weather, thereby ensuring that the plants are in a relatively stable environment. Grow in an ideal soil environment to increase production and income. [0003] A vari...
