Description

Technical Field

[0001] The present invention relates to the technical field of grain storage environment detection devices in a grain silo, and in particular to an external inspection and internal adjustment visual grain silo and a detection and adjustment method thereof. Background Art

[0002] The grain storage environment of a granary is related to the storage time and quality of the stored grain. At present, most of the existing granaries are barrel-shaped structures. In order to realize the detection of the grain storage environment of the granary, it is necessary to deploy a detection system inside the granary to realize the detection of the grain storage environment (gas environment, temperature environment, pest environment, etc.) inside the granary through the detection system.

[0003] The application document with application number CN202410620680.0 in the patent library discloses a method for inspecting the full-depth granary environment and pests with an automatic inspection device. The automatic inspection device includes a transparent cylindrical column vertically arranged inside the granary. A pulley is provided inside the column and slides vertically on a guide rail. The pulley is equipped with a camera and a temperature and humidity sensor. An insect attractant module is provided inside the column. Through the movement of the pulley and the operation of the insect attractant module, the camera and temperature and humidity sensor are used to collect pest image information on the outer wall of the column and temperature and humidity information inside the granary, thereby realizing the detection of the granary environment. However, it still has certain limitations when used:

[0004] 1) The inspection device needs to be pre-installed inside the granary. Once a failure or damage occurs, the disassembly and installation work will become more complicated;

[0005] 2) Because the inspection device is located in the middle of the granary and the camera is mounted on a pulley, its image acquisition angle is limited, making image acquisition from the back of the camera difficult.

[0006] 3) The above-mentioned inspection device can only play the role of environmental monitoring. When the granary environment is abnormal, manual intervention is required to adjust the granary environment. Summary of the Invention

[0007] In order to solve the technical problems existing in the above-mentioned background technology, the present invention provides a visual granary with external inspection and internal adjustment and a detection and adjustment method thereof.

The grain storage system includes a grain storage device for storing grain, and an environmental detection device for detecting the grain storage environment. The environmental adjustment system is used to adjust the internal environment of the granary when the grain storage environment is abnormal.

The environmental adjustment system 4 is used to adjust the internal environment of the granary when the grain storage environment is abnormal. The structure of the visual granary (the above-mentioned external inspection and internal adjustment visual granary) is described in detail below.

[0060] In this embodiment, combined with Figure 2 and Figure 3 The grain storage device 2 includes a bottom plate and a cylindrical inner cylinder 22, a detection cylinder 23 and an outer cylinder, which are sequentially sleeved with gaps on its upper side from the inside to the outside, wherein the inner cylinder 22 is configured as a mesh structure that can only accommodate pests passing through, and the detection cylinder 23 is made of transparent material. The upper end of the inner cylinder 22 is lower than the upper end of the detection cylinder 23, and an annular isolation net 24 is provided between the outer ring and the detection cylinder 23. The upper ends of the inner cylinder 22 and the outer cylinder are respectively buckled with an inner cover 25 and an outer cover 26, and the outer cover 26 forms a sealed protective barrel 21 with the outer cylinder and the bottom plate, wherein the upper end of the detection cylinder 23 is against the outer cover 26 and the outer ring is circumferentially provided with air holes 231. Of course, a gap may also be reserved between the upper end of the detection cylinder 23 and the outer cover 26, and no unnecessary restrictions are made here.

[0061] Furthermore, the bracket includes a supporting ring, and the outer ring of the outer cylinder is provided with a supporting ring platform 212 and is fixed in the supporting ring through the supporting ring platform 212.

[0062] In this embodiment, based on the above-mentioned grain storage device 2, the environmental detection device 3 includes a cylindrical rotating rack 32 rotatably arranged inside the gap between the detection cylinder 23 and the outer cylinder, and an annular detection rack 35 is vertically slidably provided on the rotating rack 32. The detection rack 35 is provided with a detection part 36 capable of detecting the granary environment. Through the rotation of the rotating rack 32 and the vertical sliding of the detection rack 35, the detection work of the grain storage environment inside the granary (protective barrel 21) can be completed through the detection part 36.

[0063] Specifically speaking, the structure of the rotating frame 32 includes an upper fixing ring 323 and a lower fixing ring 321 that are arranged opposite to each other. A vertical rod 322 is vertically provided between the two fixing rings. The detection frame 35 is vertically slidably connected to the vertical rod 322.

[0064] On the basis of the above-mentioned rotating frame 32 structure, in order to make the maintenance and replacement of the environmental detection device 3 simpler and faster, the environmental detection device 3 also includes an annular turntable arranged between the detection cylinder 23 and the outer cylinder. The lower side of the rotating frame 32 is rotated with the turntable, and the turntable is rotated and fixed with the base plate.

[0065] Combine Figure 5 Specifically, as to the fixing method of the rotating frame 32 and the turntable, an annular rotating groove is opened on the upper side of the turntable, and the lower fixed ring 321 is rotatably arranged in the rotating groove.

The first driving motor 33 can drive the lower fixed ring 321 to rotate (alternately rotate forward and reverse), thereby driving the rotating frame 32 to rotate.

[0067] Furthermore, the environmental detection device 3 also includes a second driving motor 325 that can drive the detection frame 35 to slide up and down. In order to enable the detection frame 35 to have a higher lifting accuracy under the action of the second driving motor 325 and increase the controllability of the lifting height of the detection frame 35, the second driving motor 325 is connected to the detection frame 35 through a screw 324.

With the cooperation of the insect trap 361, the plurality of cameras 362 arranged circumferentially can complete the collection of pest image information on the inner wall of the detection tube 23 without blind spots, and the temperature sensor 364 and the nitrogen concentration sensor 363 can complete the collection of temperature information and nitrogen concentration information inside the protective barrel 21, and finally complete the detection of the grain storage environment information inside the protective barrel 21. The environment detection device 3 is independently arranged between the detection barrel 23 and the outer barrel, making its disassembly, assembly and maintenance work more convenient. At the same time, in conjunction with the circumferentially arranged cameras 362, the collection of pest image information inside the granary can be more complete and reliable.
