[0001] This utility model relates to the field of soil moisture content monitoring, and in particular to a soil moisture content monitoring device. Background Technology

[0002] In soil and water conservation operations, it is necessary to monitor soil moisture content. The conventional monitoring method is to insert the probe of the monitor into the soil. For harder soils, it is necessary to pre-drill holes to form a monitoring area before inserting the probe through the drilled holes. This process is relatively cumbersome, time-consuming, and inefficient. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides a soil moisture content monitoring device that is simple to operate, reduces time consumption, and improves monitoring efficiency.

[0004] The technical solution of this utility model is as follows:

[0007] A drilling rig assembly, mounted on a base frame, includes a motor, a shaft, and a drill bit. The motor is connected to the top of the drill bit via the shaft. The diameter of the drill bit is larger than that of the shaft, and the end of the drill bit extends through the base frame to the bottom of the base frame.

[0008] The monitoring component includes a detector for monitoring soil moisture content and a probe for the detector. The detector is mounted on a support frame, and the probe is vertically mounted on one side of the rotating shaft, directly above the edge of the drill bit.

[0009] The pressing assembly includes a pressure rod located on top of the motor, and a pressure handle is provided at the top of the pressure rod.

[0010] In a further technical solution, the base frame includes a connecting block and multiple connecting rods. The multiple connecting rods are arranged in a circular array on the outside of the connecting block. The support legs are located at the ends of the connecting rods. The middle of the connecting block has a first through hole for the drill bit to pass through. The bottom end of the spring is connected to the top side of the connecting rod.

[0011] In a further technical solution, a guide post is also sleeved on the inner side of the spring, the top end of the guide post is connected to the bottom of the support frame, and a guide hole matching the guide post is opened on the connecting rod, through which the guide post passes.

[0012] In a further technical solution, a limiting block is provided at the bottom end of the guide post.

[0013] In a further technical solution, the end of the connecting rod is provided with a threaded hole, and the support leg is cylindrical with an external thread for connecting the threaded hole in the middle.

[0014] In a further technical solution, a pad is provided at the bottom end of the support leg.

[0017] The beneficial effects of this utility model are:

[0018] 1. This device can be placed at the location to be monitored by a frame support. The drill bit diameter of the drilling rig assembly is larger than that of the shaft, so that when the drill bit drills deep into the soil, there is still a gap on one side of the shaft. This is beneficial for the monitor's probe to enter the drilled hole to monitor the soil moisture content while the drill bit is penetrating the soil. When the drill bit descends, it relies on its own weight and the operator to manually press down the pressure rod. The operation is simple, time-saving, and efficient. After drilling into the soil, the spring rebound force can be used to easily pull up the drill bit by hand.

[0019] 2. The guide column ensures that the support frame remains vertical when pressed down, preventing lateral displacement and making operation more stable;

[0020] 3. Each support leg is adjustable in height to ensure the drilling angle of the drill bit, making it suitable for different terrain locations;

[0021] 4. A foot pedal is provided, which can be used with both hands and feet or separately, further facilitating the downward pressing operation of the drilling rig components;

[0027] The embodiments of this utility model will be further described below with reference to the accompanying drawings. Example

[0028] like Figures 1-2 As shown, a soil moisture content monitoring device includes a frame, a drilling rig assembly, a monitoring assembly, and a pressing assembly;

[0029] The frame includes a base frame 10 and four support legs 20 located at the bottom of the base frame 10. The base frame 10 includes a connecting block 11 and four connecting rods 12. The four connecting rods 12 are arranged in a circular array on the outside of the connecting block 11. The support legs 20 are located at the ends of the connecting rods 12. The middle of the connecting block 11 has a first through hole 13 for the drill bit 53 to pass through. The top of the base frame 10 is provided with a support frame. A spring 30 is provided between the support frame and the connecting rods 12. The support frame includes a bottom support plate 41 and a side support plate 42. The side support plates 42 are located on both sides of the top of the bottom support plate 41. The middle of the bottom support plate 41 has a second through hole of the same size as the first through hole 13.

[0030] The drilling rig assembly includes a motor 51, a shaft 52, and a drill bit 53. The diameter of the first through hole 13 is larger than the diameter of the drill bit 53. The motor 51 is connected to the top of the drill bit 53 through the shaft 52. The diameter of the drill bit 53 is larger than the shaft 52. The motor 51 is located on the top of the side support plate 42. The drill bit 53 can extend to the bottom of the base frame 10 through the first through hole 13 and the second through hole.

[0031] The monitoring components include a detector for monitoring soil moisture content and a probe 62 of the monitor 61. The monitor 61 is located between two side support plates 42 on the bottom support plate 41. The probe 62 is vertically located on one side of the rotating shaft 52. The two do not contact each other. The probe 62 is located directly above the edge of the drill bit 53.

[0032] The pressing assembly includes a pressure rod located on top of the motor 51, and a pressure handle 73 is provided at the top of the pressure rod.

[0033] The working principle of the above technical solution is as follows:

[0034] In use, the device frame is set up at the location to be monitored. The motor 51 is started to drive the drill bit 53 to rotate. The pressure handle 73 is pressed down to drive the drill bit 53 and the probe 62 to descend. The diameter of the drill bit 53 in the drilling assembly is larger than that of the rotating shaft 52, so that when the drill bit 53 drills into the soil, there is still a gap on one side of the rotating shaft 52. This is conducive to the drill bit 53 penetrating into the soil. At the same time, the probe 62 of the monitor 61 enters the drilled hole to monitor the soil moisture content. When the drill bit 53 descends, it relies on its own weight and the operator to manually press down the pressure handle. After drilling into the soil and monitoring, the drill bit 53 can be easily pulled up by hand using the spring force of the spring 30.

[0035] In another embodiment, such as Figure 1-2 As shown, a guide post 31 is also sleeved on the inner side of the spring 30. The top of the guide post 31 is connected to the bottom of the support frame. A guide hole 14 matching the guide post 31 is opened on the connecting rod 12. The guide post 31 is set through the guide hole 14. A limit block 32 is provided at the bottom of the guide post 31 to prevent the guide post 31 from disengaging from the guide hole 14.

[0036] The guide column 31 ensures that the support frame moves vertically when it is pressed down, avoiding lateral displacement and making the operation more stable.

[0037] In another embodiment, such as Figure 1-2 As shown, the end of the connecting rod 12 is provided with a threaded hole 15, and the support leg 20 is cylindrical with an external thread for connecting the threaded hole 15 in the middle. To further form a stable support, a pad 21 can be provided at the bottom of the support leg 20. The pad 21 and the bottom of the support leg 20 can be connected by a ball joint (not shown in the figure).

[0038] The rotatable support legs 20 can be adjusted up and down to adjust the support height of each support leg 20, ensuring the drilling angle of the drill bit 53. At the same time, the pad block 21 can be adjusted relative to the support legs 20 according to the support position, which is suitable for different terrain locations.

[0039] In another embodiment, such as Figure 1 As shown, the pressing assembly also includes a pedal 76, which is located on the side of the support frame.

[0040] The pedal 76 can be used with both hands and feet, or separately, to further facilitate the downward pressing operation of the drilling rig components.

[0041] In another embodiment, such as Figure 1As shown, the pressure rod includes a fixed section 71 and a telescopic section 72. The fixed section 71 is located on the top of the motor 51 and is sleeved on the outside of the telescopic section 72. Two first locking holes are opened on one side of the top of the fixed section 71 in the vertical direction. Several second locking holes 74 are opened on the side of the telescopic section 72 corresponding to the first locking holes in its length direction. Bolts 75 that can be connected to the second locking holes 74 are inserted in the first locking holes. The pressure handle 73 is located at the top of the telescopic section 72.

[0042] When adjusting the height of the pressure sensor, the bolt 75 can be unscrewed out of the second locking hole 74, the telescopic section 72 can be moved relative to the fixed section 71 to a suitable operating position, and then the bolt 75 can be screwed into the corresponding second locking hole 74 to complete the adjustment.

[0043] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
