Description

Technical Field

[0001] The present invention relates to the technical field of soil moisture detection equipment, and in particular to a soil moisture detection device for information-based water conservancy irrigation. Background Art

[0002] Water conservancy irrigation is a technical measure to supplement the water needed by crops. In order to ensure the normal growth of crops and obtain high and stable yields, crops must be supplied with sufficient water. Under natural conditions, the water requirements of crops cannot be met due to insufficient precipitation or uneven distribution. Therefore, artificial irrigation must be carried out to make up for the lack of natural rainfall. Therefore, it is necessary to use soil moisture detection equipment to detect the humidity in the land to facilitate timely watering of crops. When detecting soil humidity, soil moisture sensors are generally used for detection, and soil humidity detection is usually divided into wired humidity detectors (the detection probe is connected to the controller through wires) and wireless humidity detectors (the detection probe is connected to the client through the network or other means).

[0003] After searching, the existing patent (Announcement No.: CN215180170U) discloses a soil moisture detection device for information-based water conservancy irrigation, which includes a mounting base, a humidity detection mechanism and a photovoltaic power generation mechanism. The humidity detection mechanism includes a connecting block, a mounting block, a servo motor A, a driving gear, a driven gear, a transmission screw, a slide plate, a servo motor B, a rotating rod, a humidity detector, a drill bit, a fixing block and a fastening bolt. By starting the servo motor A, the driving gear can be driven to rotate, so that the driven gears meshing on both sides of the driving gear drive the transmission screw to rotate. At this time, the slide plate threaded on the transmission screw can move vertically downward, and then the servo motor B is started to drive the rotating rod and the drill bit to rotate, so that the humidity detector is moved into the land to detect the humidity of the land, which has the advantage of easy operation.

[0004] However, there are still some shortcomings in the above scheme:

[0005] 1. The rotation and lifting of the rotating rod and the drill bit need to be driven by dual motors, and the cost of using the device is relatively high;

[0006] 2. The humidity detector is installed between the rotating rod and the drill bit. In the process of drilling the soil using the rotating rod and the drill bit, the humidity detector is rubbed and squeezed with the soil for a long time, which is easy to cause damage to the humidity detector. Especially when encountering hard lumps in the soil during the drilling process, it is more likely to cause damage to the humidity detector, reducing the service life and detection accuracy of the humidity detector.

[0007] In view of this, the present invention proposes a soil moisture detection device for information-based water irrigation. Summary of the invention

The top of the inner tube 74 is fixedly connected to the second end cover 741, and the top of the middle tube 73 is fixedly connected to the first end cover 731. A second reset spring 76 is connected between the first end cover 731 and the fixed column 711, and a first reset spring 75 is connected between the second end cover 741 and the first end cover 731. The inner tube 74 penetrates the inside of the first end cover 731.

[0056] Furthermore, a locking component 77 is provided on the inner side of the middle tube 73, and the locking component 77 includes a movable cavity 776 symmetrically opened on the outer wall of the middle tube 73, and a fixed ring 772 and a movable ring 773 are provided inside each movable cavity 776. The fixed ring 772 is fixedly connected to the inner wall of the movable cavity 776, and the movable ring 773 is slidably connected to the inner wall of the movable cavity 776. A plug post 774 is connected between the fixed ring 772 and the movable ring 773, and the plug post 774 is fixedly connected to the movable ring 773, and the plug post 774 is slidably connected to the fixed ring 772.

[0059] In this embodiment, after the spiral drill rod 4 moves down to the specified position, the inner tube 74 is first pressed down by the second end cover 741, so that the inner tube 74 slides down inside the middle tube 73, so that the first return spring 75 is compressed, and the bottom end of the inner tube 74 squeezes the two plug posts 774, so that the two plug posts 774 move away from each other, so that the movable ring 773 approaches the fixed ring 772 to compress the third return spring 775, so that the movable ring 773 drives the plug posts 774 to be inserted into the annular limiting groove 771 opened on the inner wall of the outer tube 72, so as to limit the position between the middle tube 73 and the outer tube 72. Afterwards, the middle tube 73 is pressed down by the hand holding handle 712 through the first end cover 731.

The outer tube 72 and the wedge block 78 gradually slide and stagger, so that the wedge block 78 drives the wireless humidity detector 31 to move, so that the telescopic rod 79 extends and the spring outside the telescopic rod 79 stretches, so that the detection rod on the wireless humidity detector 31 extends out of the elliptical ball cover 53 until it is inserted into the soil hole wall opened by the spiral drill rod 4, so as to detect the soil moisture.

[0060] Working principle and use process: The installation frame 1 is moved to the work site through the moving assembly 8, and then the motor 2 is started. The motor 2 drives the large pulley 61 to rotate through its output shaft, wherein the motor 2 can be connected to an external power supply or equipped with a battery for power supply, which is a prior art and will not be described in detail here. During the rotation of the large pulley 61, the small pulley 62 can also rotate under the action of the transmission belt 63. When the large pulley 61 rotates, it can also drive the screw 64 to rotate, so that the lifting platform 9 can move up and down along the outer walls of the two guide rods 11, and the lifting platform 9 drives the hanging pipe 52 to lift and lower, and the hanging pipe 52 drives the hexagonal telescopic frame 51 to extend and adjust the drilling depth of the spiral drill rod 4. During the rotation of the small pulley 62, it can drive the hexagonal telescopic frame 51 to rotate, and the hexagonal telescopic frame 51 drives the spiral drill rod 4 to rotate through the hanging pipe 52 and the elliptical ball cover 53, and the rotating and downwardly moving spiral drill rod 4 realizes the drilling of the soil.

After the spiral drill rod 4 moves down to the specified position, the inner tube 74 is first pressed down by the second end cover 741, so that the inner tube 74 slides down inside the middle tube 73, so that the first return spring 75 is compressed, and the bottom end of the inner tube 74 squeezes the two plug posts 774, so that the two plug posts 774 move away from each other, so that the movable ring 773 approaches the fixed ring 772 to compress the third return spring 775, so that the movable ring 773 drives the plug posts 774 to be inserted into the annular limiting groove 771 provided on the inner wall of the outer tube 72, and the middle tube 73 and the outer tube 72 are limited. The locking member 77 is then engaged to allow the locking nut 78 to be moved downwardly, thereby allowing the locking nut 78 to move downwardly and the locking nut 78 to move out of the way so that the locking nut 78 can be moved downwardly.
