DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, purposes and effects realized by the present application easy to understand, the present application is further described below in combination with specific embodiments.

[0022] As Figures 1 to 7 shown, the present application provides a technical solution: a water content detector, comprising an arc-shaped platform 1, the bottom of the arc-shaped platform 1 is fixedly connected with a detector 2, the top of the arc-shaped platform 1 is provided with a soil loosening assembly for pretreating soil, both sides of the arc-shaped platform 1 are provided with a lifting assembly for inserting the detector 2 or the soil loosening assembly into soil, the other side of the arc-shaped platform 1 is provided with a rotating assembly, the rotating assembly is used for exchanging the positions of the detector 2 and the soil loosening assembly, so that only the detector 2 or the soil loosening assembly enters the soil each time, one side of the arc-shaped platform 1 is provided with a display panel 34, the display panel 34 is used for collecting detection data.

[0023] When the soil moisture content is detected, the detection head is directly inserted into the soil, which makes it difficult to insert the detection head into the soil for detection, and the detection head is prone to damage, affecting the detection data and service life of the detection head. Through the embodiments of the present scheme, in specific use, in the initial state, the detector 2 and the soil loosening assembly are located below and above the arc-shaped platform 1 respectively, the lifting assembly is started, and the lifting assembly drives the detector 2 and the soil loosening assembly to descend through the arc-shaped platform 1. During the descending process, the arc-shaped platform 1 touches the rotating assembly, so that the arc-shaped platform 1 rotates by 180 degrees. At this time, the detector 2 and the soil loosening assembly are exchanged in position, so that the soil loosening assembly faces the soil and can enter the soil. During the process that the soil loosening assembly enters the soil, the soil can be loosened, so that the soil structure in the region becomes loose. Then the arc-shaped platform 1 is reset by the lifting assembly. During the resetting process, the positions of the detector 2 and the soil loosening assembly are exchanged again, so that the detector 2 faces the soil and can enter the soil. The arc-shaped platform 1 is lowered again by the lifting assembly. At this time, the detector 2 is inserted into the soil that has been loosened and detects the moisture content of the soil. The data obtained is collected and displayed through the display panel 34. Through the above embodiments, before the detector 2 detects the soil, the soil can be loosened first. When the detector 2 is inserted into the soil, it will not be difficult to insert and prone to damage due to the hardness of the soil inside. The loosening treatment can increase the porosity and looseness of the soil, increase the gap between soil particles, thereby reducing the resistance when the detection head is inserted, and also reducing the friction between the detection head and the soil particles, making the insertion process smoother.

[0038] As Figures 1 to 2 shown, the number of teeth of the rack plate 27 is half of the number of teeth of the column gear 16.

[0039] When the column gear 16 meshes with the rack plate 27, the arc-shaped platform 1 rotates, and because the number of teeth of the rack plate 27 is half of the number of teeth of the column gear 16, the arc-shaped platform 1 rotates 180 degrees, and at this time, the detector 2 and the soil loosening assembly also rotate 180 degrees, which can achieve the effect of position replacement.

[0046] And the first time the lifting assembly is started, no current is passed between the electromagnet one 30 and the electromagnet two 31, at this time the column gear 16 can be engaged with the rack plate 27 when it is lowered, so that the detector 2 and the loosening assembly are exchanged in position, and the second time the lifting assembly is started, at this time the electromagnet one 30 and the electromagnet two 31 are passed through the current, and because the electromagnet one 30 and the electromagnet two 31 are parallel and the magnetic poles of the mutually close faces are the same, the electromagnet two 31 will squeeze the electromagnet one 30, so that the rack plate 27 and the plug-in rod 28 slide inside the connecting plate 29, when the column gear 16 is lowered for the second time, the position of the rack plate 27 is changed, and will not be engaged with the rack plate 27, so that the detector 2 can always be lowered and finally inserted into the soil for water content detection, and the position of the rack plate 27 is reset by the plug-in rod 28, after the detector 2 is reset after the entire detection is completed, the current of the electromagnet one 30 and the electromagnet two 31 is turned off, and the rack plate 27 is reset for next use.
