Description
Technical Field
[0001] The utility model relates to the technical field of moisture detection, in particular to a grain moisture detection device. Background Art
[0002] During the operation and maintenance of grain storage in granaries, the moisture content of grains directly affects the quality of grains. The moisture detection of grains is of great significance for the purchase, transportation, storage, and processing of grains. For example, Chinese Patent No. 2020218155417 discloses a capacitive grain moisture detection device, which uses two detection probes inserted into the material to be detected to detect the moisture content. However, the depth of the grain pile in the granary is relatively large, and the probe length of this capacitive grain moisture detection device is usually 10 - 15 cm. Therefore, it can only detect the moisture content of grains at a depth of 10 - 15 cm below the top surface of the grain pile, and cannot detect the moisture content deeper in the grain pile.
[0003] When it is necessary to detect the moisture content of grains deep below 1 m in the grain pile, it is necessary to first take samples of the grains deep in the grain pile, and then detect the moisture content of the samples. Since the area of the granary is very large, multiple samplings are required; it is very inconvenient to take samples deep in the grain pile, and after the samples are taken out, the internal humidity and moisture content will change, thereby affecting the detection accuracy. Summary of the Utility Model
[0004] In order to solve the above problems existing in the prior art, the utility model provides a grain moisture detection device that does not require sampling, can directly detect in situ at the depth of the grain pile, and is more convenient to use.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] A grain moisture detection device includes a housing and an end cover provided at the lower end of the housing. A slider is provided inside the housing, and a moisture detection component is fixedly provided at the lower end of the slider. Two parallel probes are provided at the lower end of the moisture detection component. Two through holes corresponding to the probes are provided at the bottom of the end cover, and the probes extend into the through holes to form a sliding connection. A connecting pipe is fixedly provided at the upper end of the housing. A driving rod for driving the slider to lift and lower inside the housing is provided inside the connecting pipe. The upper end of the driving rod extends outside the connecting pipe. A display screen is provided on the side surface of the upper end of the connecting pipe. A data line for connecting the moisture detection component and the display screen is provided inside the connecting pipe. When the slider rises to the first position, the lower end of the probe is flush with the lower end of the through hole. When the slider descends to the second position, the lower end of the probe extends outside the through hole.
[0007] By adopting the above technical solution: during use, first move the slider upward to the first position through the driving rod. At this time, the probe is completely retracted into the through hole. Then insert the housing at the lower end of the connecting pipe into the preset depth of the grain pile. Then drive the driving rod to move the slider downward to the second position, and the probe extends out of the through hole and inserts into the grain pile. The moisture content of the grain at this depth can be directly observed from the display screen. After the detection, drive the driving rod to drive the slider to move to the first position. Finally, pull out the connecting pipe from the grain pile and repeat the above actions to detect the moisture content at different areas and different depth positions in the granary. When using this kind of grain moisture detection device to detect the moisture content of the grain pile in the granary, there is no need to take samples, and it can be directly inserted into the grain pile for use, which is very convenient.
[0008] Preferably, the housing is of a cylindrical structure. Limiting convex strips are arranged along the circumferential direction on the inner wall of the housing. The slider is in clearance fit with the inner wall of the housing. A limiting groove adapted to the limiting convex platform is arranged on the side surface of the slider.
[0009] Preferably, the end cover is of a frustum structure with a larger upper part and a smaller lower part. The frustum structure can reduce the resistance when inserting into the grain pile, making the insertion more labor-saving.
[0010] Preferably, a first connecting seat is fixedly arranged at the upper end of the connecting pipe. First handles are arranged on both sides of the first connecting seat coaxially. The upper end of the driving rod slides through the first connecting seat. A second connecting seat is fixedly arranged at the upper end of the driving rod. Second handles are arranged on both sides of the second connecting seat coaxially. When the second handle approaches the first handle, the lower end of the probe extends out of the through hole. When the second handle moves away from the first handle, the lower end of the probe retracts into the through hole.
[0011] Preferably, a locking wheel for locking the driving rod is arranged on the side surface of the first connecting seat. When this device is not in use, after moving the slider to the first position, lock it through the locking wheel, so as to protect the probe and prevent the probe from being bent, deformed or damaged due to being knocked.
[0012] Preferably, the length of the connecting pipe is configured to be 80 - 200 cm. The probe and the housing itself have a certain length. Matching with the length of the connecting pipe, it can be used to detect the grain at a depth of 1 - 2 m in the grain pile.
[0013] Preferably, a scale for indicating the depth is arranged on the surface of the connecting pipe. The depth of insertion into the grain pile can be directly seen through the scale.
[0014] Therefore, the utility model has the beneficial effects of no need for sampling, being able to directly detect in situ at the depth of the grain pile, and being more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In this embodiment, the moisture detection component 30, the probes 31, and the display screen 32 are all components of an existing probe-type moisture detector and are directly purchased.
[0026] The housing 10 has a cylindrical structure. A circumferentially distributed limiting rib 100 is provided on the inner wall of the housing 10. The slider 20 is in clearance fit with the inner wall of the housing 10. A limiting groove 200 adapted to the limiting boss is provided on the side surface of the slider 20.

[0030] Combined with the attached drawings, the principle of the present utility model is as follows: In the initial state, the states of the slider 20, the moisture detection component 30, and the probe 31 are as Figure 3 shown. When in use, as Figure 6 shown, insert the housing at the lower end of the connecting pipe into the preset depth of the grain pile. Hold the first handle with one hand and the second handle with the other hand, and drive the second handle closer to the first handle. At this time, the slider descends to the second position, and the probe extends from the through hole to the state as Figure 5 shown. The probe is inserted into the grain pile for moisture detection. The moisture content of the grain at this depth can be directly observed from the display screen. After the detection is completed, pull the second handle away from the first handle, and the slider resets to the first position. Pull out the connecting pipe from the grain pile, and repeat the above actions to detect the moisture content at different areas and different depth positions in the granary. When using this kind of grain moisture detection device to detect the moisture content of the grain pile in the granary, there is no need to take samples, and it can be directly inserted into the grain pile for use, which is very convenient. When not in use, move the slider to the first position and lock the driving rod through the locking wheel.
