Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] Please combine Figures 1-4 This embodiment of a portable grain appearance quality testing device includes a cylinder 1. A partition 2 is fixedly installed inside the cylinder 1, dividing the interior of the cylinder 1 into upper and lower parts. The lower part is defined as a battery compartment 4, which can be fitted with dry cell batteries. A lower end cap 16 is threadedly connected to the bottom of the battery compartment 4.

[0023] The upper part is designated as observation chamber 3, which contains a tray 5 for holding the grain to be observed and a lighting assembly 7. First, an annular mounting plate 6 is fixedly connected to the top of observation chamber 3. The tray 5 is installed in the middle of the annular mounting plate 6 and is used to hold the grain to be observed. The tray 5 is made of transparent glass. Additionally, an annular buffer gasket 19 is provided on the upper surface of the annular mounting plate 6, located outside the tray 5. The buffer gasket 19 is higher than the tray 5, and when the grain is placed on the tray 5, the buffer gasket 19 can restrain the grain.

[0024] The lighting assembly 7 includes a light strip 71 and a reflector bowl 72. First, the light strip 71 is installed on the lower surface of the annular mounting plate 6. The light strip 71 can be a full-spectrum, low-brightness light strip. The upper end of the reflector bowl 72 is fixedly connected to the annular mounting plate 6, and the lower end is fixedly connected to the partition plate 2, with the light strip 71 located inside the reflector bowl 72. The light strip 71 is electrically connected to the battery in the battery compartment 4. Therefore, when the light strip 71 is turned on, the light, after being reflected by the reflector bowl 72, passes through the support plate 5.

[0025] An upper observation frame 8 is movably mounted on top of the cylinder 1, and a pressure plate 9 is installed inside the upper observation frame 8. Similar to the support plate 5, the pressure plate 9 is made of transparent glass. The thickness of both the support plate 5 and the pressure plate 9 must be less than 2 mm, and the glass surface must be flat and smooth. This reduces light loss when passing through the support plate 5 and the pressure plate 9, resulting in clearer subsequent imaging and easier observation. Additionally, a magnifying glass 10 is installed inside the upper observation frame 8, positioned above the pressure plate 9.

[0026] To facilitate the placement of the grains to be observed on the tray 5, a guide hole 12 is provided on the cylinder 1. A guide plate 11 is slidably installed in the guide hole 12, and the upper end of the guide plate 11 is fixedly connected to the upper observation frame 8. A control button 13 is slidably installed on the outer wall of the cylinder 1, and the control button 13 is fixedly connected to one of the guide plates 11.

[0027] Therefore, when the control button 13 is moved, the guide plate 11 and the upper observation frame 8 are moved, so that the upper observation frame 8 is close to or away from the supporting plate 5. A magnetic buckle 14 is installed on the bottom of the upper observation frame 8 and the cylinder 1, and when the upper observation frame 8 is close to the cylinder 1, the magnetic buckle 14 is attached.

[0028] In order to protect the above magnifying glass 10, the supporting plate 5 and the pressing plate 9, a thread is formed on the side of the cylinder 1, and an upper end cover 15 is arranged, which covers the upper observation frame 8 when the upper observation frame 8 is attached to the cylinder 1, and the upper end cover 15 is threadedly connected with the cylinder 1.

[0029] The implementation process and principle of the grain appearance quality detection device convenient to carry in the embodiment of the application are as follows:

[0030] In the unused state, the guide plate 11 is located in the guide hole 12, the upper observation frame 8 and the cylinder 1 are connected through the magnetic buckle 14, and the upper end cover 15 is arranged outside the upper mounting frame to protect the upper observation frame 8 and the structures such as the magnifying glass 10 and the pressing plate 9 in the inside.

[0031] In use, the upper end cover 15 is first rotated and taken out, the upper observation frame 8 and the cylinder 1 are separated by moving the control button 13, and the supporting plate 5 is exposed at this time, and the grain to be observed is placed on the supporting plate 5.

[0032] The upper observation frame 8 is reset through the control button 13, and the upper observation frame 8 and the cylinder 1 are connected through the magnetic buckle 14. Therefore, the buffer washer 19 is arranged on the annular mounting plate 6. When the upper observation frame 8 is reset, the pressing plate 9 is in contact with the upper end surface of the buffer washer 19. That is, the grain is fixed between the supporting plate 5 and the pressing plate 9 through the supporting plate 5, the pressing plate 9 and the buffer washer.

[0033] The lamp strip 71 is powered on, and the light passes through the reflecting bowl 72 and then passes through the supporting plate 5, the pressing plate 9 and the magnifying glass 10 in sequence. The user can observe the grain through the magnifying glass 10.

[0034] Firstly, the grain is fixed between the supporting plate 5 and the pressing plate 9, and the light can be supplemented through the lighting assembly 7. At the same time, the magnifying glass 10 can magnify the grain, so that the user can intuitively and clearly observe whether the grain is full, complete and the color of the grain. At the same time, the structure of the application is simple, small and convenient to operate and carry. The above embodiment is only a preferred embodiment of the application, and cannot be used to limit the protection range of the application. Any non-essential change and replacement made by the person skilled in the art on the basis of the application belongs to the range of the application.
