[0002] Grain refers to the general term for various plant seeds used in cooking food, and can also be generally referred to as "cereals". Grain crops are rich in nutrients, mainly protein, vitamins, dietary fiber, fat, starch, etc., and are also generally referred to as edible raw and finished grains such as cereals, beans and potatoes. The concept of grain refers to cereals, including wheat, beans, coarse grains and rice, etc. Grain is easily affected by moisture and mold during storage, which affects its consumption. Therefore, it is necessary to use monitoring devices to monitor the humidity of stored grains.
[0003] The existing grain moisture monitoring device has a relatively simple structure. When in use, it is generally directly fixed on the grain box, and its monitoring probe is inserted into the grain to achieve real-time monitoring of the moisture condition of the grain. However, when encountering a deeper grain box, the moisture degree of grains at different depths is different. The monitoring result of a single position is not convincing. Utility Model Content

[0006] 2. Technical solution
[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0013] Furthermore, the position of the lower end of the threaded screw is consistent with the position of the lower end of the monitoring probe.
[0014] 3. Beneficial effects
[0015] Compared with the prior art, the advantages of the present invention are:
[0016] (1) The timing module in the processing module of this solution can control the screw motor to start every half an hour.

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0025] Example
[0026] like Figure 1-4 As shown, a grain moisture monitoring device includes a screw motor 1 and a grain storage box 2. The screw motor 1 is fixedly installed on the upper edge of the outer wall of the grain storage box 2. A threaded screw 11 is arranged inside the screw motor 1. The upper end of the threaded screw 11 is rotatably connected to a bearing 3. The outer circumferential surface of the bearing 3 is fixedly connected to a connecting rod 4. The upper end of the connecting rod 4 is fixedly connected to a mounting seat 5. The upper end of the mounting seat 5 is fixedly connected to a processing module 6 and a humidity sensor 7. The lower end of the connecting rod 4 is fixedly connected to a monitoring probe 8. A pair of connecting blocks 12 are fixedly connected to one side of the screw motor 1. One end of the pair of connecting blocks 12 is fixedly connected to a limiting block 13. The pair of limiting blocks 13 are symmetrically distributed on both sides of the connecting rod 4. The processing module 6 includes a timing module and a data transmission module. The screw motor 1, the processing module 6, the humidity sensor 7 and the monitoring probe 8 are electrically connected.
[0027] When in use, the timing module in the processing module 6 can control the screw motor 1 to start at regular intervals every half an hour. After the screw motor 1 is turned on, it can drive the threaded screw 11 to rotate and extend. During the rotation and extension process, the threaded screw 11 can drive the connecting rod 4 to move up and down synchronously. During the up and down movement of the connecting rod 4, the monitoring probe 8 can monitor grains at different depths. The monitoring results are sent to the data terminal for statistics by the data transmission module, making the humidity monitoring results more convincing and greatly improving the monitoring effect.
[0028] like Figure 1-3 As shown, the limit block 13 is rotatably connected to a roller 14 on one side close to the connecting rod 4 , and both sides of the connecting rod 4 are grooved with limit guide grooves 41 , and the outer circumferential surface of the roller 14 contacts the inner wall of the limit guide groove 41 .
[0029] When in use, when the connecting rod 4 moves up and down, the limit block 13 can limit the connecting rod 4 to ensure that the connecting rod 4 can move up and down along a straight line. When the limit block 13 limits the connecting rod 4, the roller 14 can greatly reduce the friction between the limit block 13 and the connecting rod 4, thereby improving the smoothness of the connecting rod 4 in the process of moving up and down, reducing the wear between parts, and increasing the service life.
[0030] like Figure 4 As shown, the interior of the connecting rod 4 is hollow, and the connection line between the humidity sensor 7 and the monitoring probe 8 is located inside the connecting rod 4 .
[0031] During use, since the connection line between the humidity sensor 7 and the monitoring probe 8 is located in the connecting rod 4, when the connecting rod 4 moves up and down in the grain, the connection line will not be subject to the friction caused by the grain, so as to avoid damage to the surface of the connection line.
[0032] like Figure 1-2 As shown, the position of the lower end of the threaded screw 11 is consistent with the position of the lower end of the monitoring probe 8.
[0033] When in use, the threaded screw 11 and the monitoring probe 8 move up and down synchronously. The position of the lower end of the threaded screw 11 is the position of the monitoring probe 8 in the grain, which is convenient for personnel to observe the specific depth of the monitoring probe 8 in the grain.
[0034] In summary, the specific working process of this scheme is as follows: the timing module in the processing module 6 can control the screw motor 1 to start regularly every half an hour. After the screw motor 1 is turned on, it can drive the threaded screw 11 to rotate and extend. The threaded screw 11 can drive the connecting rod 4 to move up and down synchronously during the rotation and extension process. The connecting rod 4 can cooperate with the monitoring probe 8 to monitor the grains at different depths during the up and down movement. The monitoring results are sent to the data terminal for statistics by the data transmission module, making the humidity monitoring results more convincing and greatly improving the monitoring effect.
[0035] Among them, when the connecting rod 4 moves up and down, the limit block 13 can limit the connecting rod 4 to ensure that the connecting rod 4 can move up and down along a straight line. When the limit block 13 limits the connecting rod 4, the roller 14 can greatly reduce the friction between the limit block 13 and the connecting rod 4, thereby improving the smoothness of the connecting rod 4 in the process of moving up and down, reducing the wear between parts, and improving the service life.
[0036] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
