Specific embodiments

[0021] Next, the technical solutions in the embodiments of this utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this utility model.

[0022] As Figures 1-5 shown, a grain moisture detection device includes a control rod 1 and a detection rod 2. A display screen 4 is arranged on the control rod 1. A plurality of extension rods 3 are connected between the control rod 1 and the detection rod 2. Connection components are arranged at the connection parts of the control rod 1, the detection rod 2, and the extension rods 3. The connection component includes a rotating sleeve 11 rotatably connected to one end of the circumferential side of the detection rod 2 and the extension rod 3 through a bearing, a connecting sleeve 12 slidably connected to the circumferential side of the rotating sleeve 11 through a slider 121 and a sliding groove 111, a limit seat 10 welded to one end of the control rod 1, and a spring 13 arranged in the sliding groove 111. Two ends of the spring 13 are respectively connected to the slider 121 and the upper side of the sliding groove 111. An L-shaped limiting block 122 is integrally formed at one end of the connecting sleeve 12 close to the limit seat 10. An arc-shaped rotating groove 101 is opened in the limit seat 10. A limiting groove 102 and an insertion slot 103 are respectively opened at both ends of the rotating groove 101. The insertion slot 103 communicates with the side of the limit seat 10 close to the connecting sleeve 12, and the limiting block 122 can move in the rotating groove 101 through the insertion slot 103 and be inserted into the limiting groove 102;

[0023] Detection components for detecting the moisture of grains are arranged inside the control rod 1 and the extension rods 3 and at the front end of the detection rod 2.

[0024] During use, the staff connect several extension rods 3 between the control rod 1 and the detection rod 2 according to the depth of the grain to be detected, and make the extension rods 3 fit against the opposite sides of the control rod 1 and the detection rod 2. Then, the staff rotate the rotating sleeve 11 so that the limiting block 122 is in the same straight line as the insertion slot 103. After that, the staff push the connecting sleeve 12 so that the limiting block 122 is inserted into the insertion slot 103. When the limiting block 122 moves into the rotating slot 101, the staff rotate the rotating sleeve 11 so that the limiting block 122 moves in the rotating slot 101 to the limiting slot 102. Under the action of the spring 13, the limiting block 122 moves upward and is inserted into the limiting slot 102, preventing the extension rod 3 from detaching from the control rod 1 and the detection rod 2 during use, ensuring the reliability of the detection device during use. At the same time, the length of the detection device is extended, enabling the staff to detect the moisture content of the grain deep in the granary. When the grain moisture detection is completed, the staff push the connecting sleeve 12 so that the limiting block 122 disengages from the limiting slot 102 and enters the rotating slot 101. Then, rotate the rotating sleeve 11 so that the limiting block 122 moves to the insertion slot 103, and under the action of the spring 13, the limiting block 122 disengages from the limiting seat 10. After that, the staff remove the extension rod 3 from the control rod 1 and the detection rod 2, thereby reducing the length of the detection device and facilitating the storage of the detection device.

[0025] In this embodiment, signal transmission lines 6 are inserted into the control rod 1, the detection rod 2, and the extension rod 3. The signal transmission lines 6 are connected through USB interfaces 601. During use, the detection information of the detection component can be transmitted to the control rod 1 through the signal transmission line 6 and displayed on the display screen 4, improving the convenience for the staff to observe the data.

[0026] In this embodiment, the detection component includes a moisture detector 7 installed in the control rod 1, the extension rod 3, and the detection rod 2 by bolts, and a conical shell 8 welded to the front side of the detection rod 2. The moisture detector 7 is electrically connected to the signal transmission line 6. A plurality of detection holes 801 are provided on the circumferential sides of the control rod 1 and the extension rod 3 and on the outer side of the conical shell 8. The diameter of the detection holes 801 is smaller than the diameter of the grain. During use, the air between the grains passes through the detection holes 801 and contacts the moisture detector 7, enabling the moisture detector 7 to detect the air in the granary and transmit the detection result to the display screen 4 through the signal transmission line 6 to ensure the accuracy of the detection device.

[0027] In this embodiment, a power supply 5 connected to the display screen 4 is installed in the handle of the control rod 1 by bolts. A charging port 501 is provided on the side of the power supply 5 away from the display screen 4. During use, the power supply 5 can provide energy for the detection device to ensure the normal operation of the detection device. When the power of the power supply 5 is exhausted, the staff can charge the power supply 5 through the charging port 501 to ensure the reuse of the power supply 5.

[0028] In this embodiment, a cover 9 is threadedly connected to the top end of the handle of the control rod 1. During use, the cover 9 can prevent external water flow and dust from entering the power supply 5 through the charging port 501, extending the service life of the power supply 5.

[0029] In this embodiment, inclined surfaces are provided on both the upper and lower sides of the limit seat 10. The inner side surfaces of the inclined surfaces are in contact with the circumferential side surfaces of the control rod 1 or the extension rod 3, and the circumferential side surfaces of the connecting sleeve 12. A conical protrusion that is integrally formed on the lower side surface of the connecting sleeve 12 and is in contact with the circumferential side surface of the extension rod 3 or the detection rod 2 is provided. A gap is left between the conical protrusion and the opposite side surface of the rotating sleeve 11. During use, the inclined surfaces and the conical protrusion can reduce the components of the grain when inserting the detection device, improving the convenience for the staff when inserting the detection device.

[0030] In this embodiment, sealing gaskets 14 with sealed fit are provided on the side surfaces where the control rod 1, the detection rod 2, and the extension rod 3 are in contact. During use, the sealing gaskets 14 improve the sealing performance when the control rod 1, the detection rod 2, and the extension rod 3 are connected, preventing external dust and moisture from entering the USB interface 601.

[0031] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
