Description

Technical Field

[0001] The utility model belongs to the technical field of soil monitoring instruments, and in particular relates to a soil moisture monitoring instrument. Background Art

[0002] Soil moisture refers to the water content in the soil. When conducting profile observations in the field, the degree of moisture of the soil layer is distinguished, generally measured as dry, slightly moist, moist, damp, and wet. If you test it with your hand, if you feel a noticeable coolness, it is dry; if it is slightly cool but not moist, it is slightly moist; if it is noticeably moist and can be pressed into various shapes without any wet marks, it is moist; if no water seeps out when squeezed by hand, but there are wet marks, it is damp; if you squeeze it with your hand and waterlogging appears, it is wet. In modern agricultural planting, in order to provide crops with corresponding soil moisture, it is necessary to monitor soil moisture.

[0003] The commonly used soil moisture monitor inserts the probe into the soil during use. Since different crops have different root depths, it is necessary to detect the moisture at different depths of the soil. The traditional soil moisture monitor lacks a depth positioning device. When in use, it is necessary to bend over to observe the insertion depth of the probe, which is not only inconvenient to operate, but also generally multiple points are selected during monitoring, and the insertion depth is observed each time, which affects the monitoring efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a soil moisture monitoring instrument, which does not need to bend over to observe the insertion depth of the detection probe during monitoring, and is convenient for measurement.

[0006] Furthermore, there are three detection probes.

[0007] Furthermore, through holes are provided in the middle of the baffle plate and the middle of the extension plate, and the three detection probes pass through the three through holes respectively.

[0008] Furthermore, the connecting component includes a ring fixedly connected to the top of the extension plate, the ring is slidably connected to the detection probe, the top of the ring is fixedly connected to elastic sheets equidistantly distributed around the axis of the ring, and the side walls of the elastic sheets are fixedly connected to connecting sheets.

[0009] Furthermore, the locking component includes a sleeve, and the plurality of elastic sheets at the top end of the collar are rotatably connected to the inside of the sleeve, and the side wall of the sleeve is provided with an opening.

[0010] Furthermore, the top and bottom ends of the sleeve are fixedly connected to limit rings, and both ends of the sleeve side wall opening are fixedly connected to elastic plates.

[0011] Furthermore, the locking component also includes a bolt for locking the two tensioning plates, the bolt passes through the two tensioning plates, and a wing nut is threadedly connected to the bolt.

[0012] Compared with the prior art, the beneficial effects of the utility model are: firstly, the position of the limit component is adjusted according to the depth of the soil to be monitored, and when monitoring, the detection probe is directly inserted to make the bottom end of the limit component contact with the ground. There is no need to bend over to observe the insertion depth of the detection probe during monitoring, which is convenient for measurement. When multiple points are measured, the monitoring efficiency can be greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0019] like Figure 1-3As shown, a soil moisture monitoring instrument includes a detector body 1 and a detection probe 2, the detection probe 2 is fixedly connected to the bottom end of the detector body 1, the side wall of the detection probe 2 is slidably connected to a limiting component 3, the limiting component 3 includes a baffle 31, both sides of the baffle 31 are fixedly connected to an extension plate 32, the top of the extension plate 32 is fixedly connected to a connecting component 34, and the connecting component 34 is provided with a locking component 4 for locking the connecting component 34 on the detection probe 2.

[0020] According to the above structure, when in use, first adjust the position of the limit component 3 according to the depth of the soil to be monitored. When monitoring, directly insert the detection probe 2 so that the bottom end of the limit component 3 contacts the ground. There is no need to bend over and observe the insertion depth of the detection probe 2 during monitoring, which is convenient for measurement. When multiple points are measured, the monitoring efficiency can be greatly improved.

[0021] like Figure 2 and 3 As shown, there are three detection probes 2 , and through holes 33 are opened in the middle of the baffle 31 and the middle of the extension plate 32 , and the three detection probes 2 pass through the three through holes 33 respectively.

[0022] According to the above structure, the baffle 31 can slide along the detection probe 2, thereby adjusting the position of the limiting component 3, so as to limit the insertion depth of the detection probe 2 during monitoring.

[0023] like Figure 3 As shown, the connecting component 34 includes a ring 341 fixedly connected to the top of the extension plate 32, the ring 341 is slidably connected to the detection probe 2, the top of the ring 341 is fixedly connected with elastic sheets 342 equidistantly distributed around the axis of the ring 341, the side wall of the elastic sheet 342 is fixedly connected with a connecting sheet 343, the locking component 4 includes a sleeve 41, a plurality of elastic sheets 342 at the top of the ring 341 are rotatably connected to the inside of the sleeve 41, the side wall of the sleeve 41 is provided with an opening, the top and bottom ends of the sleeve 41 are fixedly connected with a limiting ring 42, both ends of the opening of the side wall of the sleeve 41 are fixedly connected with a tension plate 43, the locking component 4 also includes a bolt 44 for locking the two tension plates 43, the bolt 44 passes through the two tension plates 43, and a wing nut 45 is threadedly connected to the bolt 44.

[0024] According to the above structure, when adjusting the position of the baffle 31, first loosen the two wing nuts 45 so that the connecting component 34 can slide up and down along the detection probe 2. At this time, adjust the position of the baffle 31. After adjusting the baffle 31 to the corresponding position, tighten the wing nuts 45 to make the two elastic plates 43 approach each other, thereby tightening the opening of the sleeve 41, and then the sleeve 41 presses the elastic sheet 342 against the side wall of the detection probe 2, which plays a role in fixing the overall position of the limiting component 3.

There is no need to bend over to observe the insertion depth of the detection probe 2 during monitoring, which is convenient for measurement. When multiple points are measured, the monitoring efficiency can be greatly improved. The baffle 31 can slide along the detection probe 2 to adjust the position of the limiting component 3, which is convenient for limiting the insertion depth of the detection probe 2 during monitoring. When adjusting the position of the baffle 31, first loosen the two wing nuts 45 so that the connecting component 34 can slide up and down along the detection probe 2. At this time, the position of the baffle 31 is adjusted. After the baffle 31 is adjusted to the corresponding position, the two elastic plates 43 are brought close to each other by tightening the wing nuts 45, thereby tightening the opening of the sleeve 41, and then the sleeve 41 presses the elastic sheet 342 against the side wall of the detection probe 2, which plays a role in fixing the overall position of the limiting component 3. In this way, when monitoring, the detection probe 2 can be inserted until the bottom end of the baffle 31 contacts the ground.
