[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] As Figure 1 shown, the present invention provides a cultivated land soil moisture monitoring device, including a housing 1. A channel is provided at the bottom of the housing 1, and a power mechanism and a monitoring probe 6 are provided inside the housing 1. The monitoring end of the monitoring probe 6 is close to the channel, and the monitoring probe 6 can slide out or slide into the channel along the vertical direction. The power mechanism is arranged inside the housing 1 and is connected to the monitoring probe 6, and the power mechanism is used to drive the monitoring probe 6 to perform the action of sliding out or sliding into the channel.

[0027] Among them, the monitoring probe 6 is rotatably connected to the lifting plate 4 through a bearing.

[0028] A keyway 601 is provided on the upper end face of the monitoring probe 6, a key shaft 8 is arranged in the keyway 601, and the key shaft 8 is in sliding contact with the keyway 601. The upper end of the key shaft 8 extends outside the keyway 601 and is fixedly connected to the inner wall of the housing 1. A driving member for driving it to rotate is arranged inside the housing 1 and is connected to the key shaft 8.

[0029] When in use, the device is placed at the monitoring point, and the monitoring probe 6 is driven by the power mechanism to slide out of the channel downward. The monitoring probe 6 continuously moves downward and gradually inserts into the cultivated land soil, so as to install the monitoring probe 6 in the cultivated land soil.

[0030] At the same time, the key shaft 8 is driven to rotate by the driving member, and the key shaft 8 drives the monitoring probe 6 to rotate through the keyway 601, so as to drive the monitoring probe 6 to spiral into the cultivated land soil, improve the insertion speed of the monitoring probe 6 into the cultivated land soil, and at the same time the monitoring probe 6 is completely and tightly attached to the cultivated land soil, ensuring the monitoring accuracy of the monitoring probe 6 for the moisture of the cultivated land soil.

[0031] In this embodiment, the number of the monitoring probes 6 is at least two, and multiple monitoring probes 6 are all connected to the output end of the power mechanism. Therefore, at least two monitoring probes 6 can be inserted simultaneously through this device, and multiple monitors can be performed on the same location in real time at one time to obtain multiple groups of data, changing the traditional single-point monitoring method, avoiding the special points in a certain place of the cultivated land soil during the monitoring process from affecting the monitoring judgment of the entire area, and further improving the monitoring accuracy of the soil moisture in the cultivated land.

[0032] In this embodiment, the power mechanism includes a lifting plate 4 arranged in the housing 1, and the lifting plate 4 can move up and down in the housing 1. A motor 2 is installed in the housing 1, the output shaft of the motor 2 is connected to a threaded rod 3, and the lifting plate 4 is threadedly sleeved on the threaded rod 3 through a thread ring.

[0033] A plurality of guide rods 5 are fixedly arranged in the housing 1, and the lifting plate 4 is slidably sleeved on the plurality of guide rods 5 to prevent the lifting plate 4 from rotating.

[0034] When the power mechanism is started, the motor 2 drives the threaded rod 3 to rotate, the threaded rod 3 drives the lifting plate 4 to move up and down (under the guiding action of the guide rod 5, the lifting rod 4 cannot rotate), and the lifting plate 4 drives the monitoring probe 6 connected thereto to move up or down, so as to drive the monitoring probe 6 to slide out or slide into the channel.

[0035] In this embodiment, a conical head 7 is connected to the lower end of the monitoring probe 6, and a spiral blade is connected to the side wall of the conical head 7, so that the front end of the monitoring probe 6 is equivalent to a drill bit, which is more conducive to the monitoring probe 6 moving downward and drilling into the cultivated land soil.

[0036] In this embodiment, scale lines are arranged on the outer surface of the monitoring probe 6 along its length direction, so that when the staff inserts the monitoring probe 6 into the cultivated land soil, the depth of the monitoring probe 6 inserted into the cultivated land soil can be intuitively read, and further the moisture data at the corresponding depth of the cultivated land soil can be determined.

[0037] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
