[0002] At present, the traditional methods for measuring leaf moisture content mainly include drying method, chemical method, electrical measurement method, etc., but these methods are destructive, complex to operate, long in measurement time, and have certain limitations.

The device uses the detector body as the device body. When detection is required, the support plate is first opened and the leaves are flattened and placed on the support plate, and then the support plate is merged again, and then the light module is started to illuminate the leaves, and then data conversion is performed through the detection module, and then the adjustment rod is driven to move parallel inside the empty slot to switch different illumination points for multi-point detection.

[0016] The principles and advantages of this solution are:

[0017] 1. Pour the leaves to be inspected into the filter box through the inlet. The excess water on the leaves will be filtered by the filter plate, so that the leaves and the water attached to the leaves will be retained on the filter plate and the inspection plate. Since both sides of the filter box are inclined, the leaves retained on the filter plate will move toward the position of the inspection plate, that is, the leaves will be concentrated on the inspection plate, realizing the separation of excess water on the leaf surface and facilitating subsequent further operations.

[0018] 2. The first rack is set to limit the vertical movement of the detection plate during the period of filtering excess moisture on the blades, to ensure that the detection plate can move vertically downward under the combined gravity of the blades and the moisture attached to the blades only after the excess moisture on the blades has been filtered out, so as to prepare for subsequent alarm prompts.

[0019] 3. During the inspection of the weight of moisture attached to the blades by the detection board, if the weight of moisture attached to the blades does not exceed the standard, the detection board will not drive the vertical block to move vertically downward, so that the bell and the impact block will always remain at the same height, and the impact block will continue to hit the bell, causing the bell to make a sound, thereby reminding the workers that the weight of moisture attached to the blades being inspected does not exceed the standard; if the weight of moisture attached to the blades exceeds the standard, the detection board will drive the vertical block to move vertically downward, and then the impact block can act on the bell first, and then on the iron sheet. Since the sounds made by the bell and the iron sheet are different, the workers can conclude that the weight of moisture attached to the blades being inspected exceeds the standard by distinguishing the different sounds.

[0020] 4. When the impact block acts on the iron sheet, the iron sheet will first make a sound, and then, under the action of the impact block, it will move closer to the position of the slider. Then, the slider will hit the iron sheet and make a second sound, thereby enhancing the effect of the sound produced by the iron sheet and improving the utilization rate of the sound produced by the iron sheet. Because the impact block can make reciprocating motion, the combined action of the slider and the impact block can increase the frequency of the impact on the iron sheet, making the sound produced by the iron sheet more frequent and louder, thereby enhancing the inspection effect of the moisture content of the blades and improving the efficiency of the inspection of the moisture content of the blades.

[0021] 5. As the slider reciprocates, the movable block moves synchronously. During this motion, it continuously strikes the copper sheet, causing it to emit a sound. This mixing of the sound from the iron and copper sheets creates reverberation. This propagation of reverberation provides a more effective warning, allowing workers to more accurately identify the source of the sound and quickly determine if the moisture content of the blade being tested exceeds the standard, further improving the efficiency of moisture testing.

[0022] 6. Under the combined action of the movable block and the fourth spring, the copper disc reciprocates toward the sound hole. During this movement, the contact between the copper disc and the sound hole adjusts the amount of sound transmitted through the hole, causing the sound to fluctuate in volume. This modulated sound intensity increases the worker's sensitivity to sound, thereby comprehensively enhancing the effectiveness of leaf moisture testing.

[0023] 7. During the period when the impact block impacts the iron sheet, the auxiliary block cooperates with the impact block, so that the impact block and the auxiliary block can hit the iron sheet alternately, thereby making the frequency of the sound emitted by the iron sheet higher and the sound louder, ensuring that the sound emitted by the iron sheet is better transmitted and the transmission distance is farther, ensuring that the workers can receive the information that the moisture attached to the blades on the detection plate exceeds the standard.

[0024] 8. The brush block drives the bristle layer to rotate, and then the bristle layer can clean the dust blocked in the sound hole, so that the dust no longer blocks the sound hole, so that the dust does not interfere with the propagation of sound, thereby enhancing the effect of sound transmission through the sound hole, and ensuring that the sound can be transmitted to the outside world more fully and comprehensively through the sound hole.

[0025] 9. The lifting block drives the brush roller to move vertically, and then the brush roller can drive the leaves trapped on the filter plate to move toward the position of the detection plate, ensuring that all the leaves can be accumulated on the detection plate. At the same time, because the brush roller can also rotate, the brush roller has a stronger force, allowing the brush roller to clean the leaves trapped on the filter plate more comprehensively and thoroughly, ensuring that no leaves are left on the filter plate, which improves the accuracy of the detection plate in detecting moisture attached to the leaves.

[0026] 10. The brush roller cleans the blades on the filter plate so that there will be no blade residue on the filter plate, thereby ensuring that the blades will not block the filter plate, thereby enhancing the filtering effect of the filter plate and improving the filtering efficiency of the filter plate.

[0027] 11. The brush roller is provided with cleaning teeth to enhance the force of the brush roller, ensuring that the blades remaining on the filter plate can be cleaned more completely and thoroughly, further enhancing the cleaning effect of the brush roller and improving the cleaning efficiency of the brush roller.

[0028] 12. While the brush roller is cleaning the filter plate, the long block moves synchronously with the lifting block. During this movement, the long block drives the first electrode sheet toward the location of the second electrode sheet until the first and second electrode sheets are in contact, and the warning light is energized. When the warning light is energized, it conveys the message that the brush roller's cleaning work has been completed. If the sound emitted at this time is like a bell, it indicates that the moisture content of the blades is within the controllable range. If the sound emitted at this time is a reverberation of iron and copper sheets, it indicates that the blade moisture content test has failed. In other words, with the help of the warning light, workers can better judge the progress and results of the blade moisture content test, thereby improving the quality of the blade moisture content test.

[0057] Specific implementation process:

[0058] The leaves to be inspected are poured into the filter box 3 through inlet 44. Excess moisture on the leaves is filtered by the filter plate 4, trapping the leaves and any moisture attached to them on the filter plate 4 and the inspection plate 8. Because both sides of the filter box 3 are inclined, the leaves trapped on the filter plate 4 move toward the inspection plate 8, concentrating and accumulating on the inspection plate 8. This separates excess moisture from the leaf surfaces and facilitates subsequent operations. After filtration, the water flows through the conduit 5 to the outlet 45, thereby filtering and collecting the excess moisture.

[0059] After the excess moisture on the blades is filtered out, the servo motor 38 is activated, and its output shaft drives the screw to rotate. As the screw rotates, the nut holder 43 drives the lifting block 27 in vertical reciprocating motion along the length of the guide rod 42. During the movement of the lifting block 27, it drives the telescopic rod to move synchronously. During the movement of the telescopic rod, the brush roller 28 also moves synchronously. During this movement, the brush roller 28 drives the blades remaining on the filter plate 4 toward the location of the detection plate 8, ensuring that all the blades are deposited on the detection plate 8. Simultaneously, the second gear 47 and the second rack 48 engage, further driving the brush roller 28 to rotate. Because the brush roller 28 can still rotate, its force is stronger, allowing it to more comprehensively and thoroughly clean the blades remaining on the filter plate 4, ensuring that no blades remain on the filter plate 4. This improves the accuracy of the detection plate 8 in measuring the weight of the blades and the amount of moisture attached to them.

[0060] The cleaning teeth 35 are provided on the brush roller 28 to enhance the force of the brush roller 28, ensuring that the residual blades on the filter plate 4 can be cleaned more completely and thoroughly, further enhancing the cleaning effect of the brush roller 28 and improving the cleaning efficiency of the brush roller 28.

[0061] The first rack is provided to limit the vertical movement of the detection plate 8 during the period when the blades filter excess moisture, to ensure that the detection plate 8 can move vertically downward under the combined gravity of the blades and the moisture attached to the blades only after the blades have finished filtering, to prepare for subsequent alarm prompts.

[0062] During the rotation of the screw, the first gear 37 rotates synchronously. During the rotation of the first gear 37, due to the engagement between the first gear 37 and the first rack, the first rack moves along the length direction of the limit block 9 to a position away from the filter box 3.

[0063] After the first rack no longer limits detection plate 8, detection plate 8 begins to detect the weight of the blades on it. Simultaneously, elliptical disc 39 rotates synchronously with shaft 36. During its rotation, when the long axis of elliptical disc 39 contacts impact block 12, impact block 12 moves toward the location of bell 15, compressing the fifth spring. When the short axis of elliptical disc 39 contacts impact block 12, impact block 12 returns to its original position under the action of the fifth spring.

[0064] Therefore, during the inspection of the weight of moisture attached to the blades by the detection plate 8, if the weight of moisture attached to the blades does not exceed the standard, the detection plate 8 will not drive the vertical block 13 to move vertically downward, so that the bell 15 will always maintain the same height as the impact block 12, and the impact block 12 will continue to hit the bell 15, causing the bell 15 to make a sound, thereby reminding the workers that the weight of moisture attached to the blades being inspected this time does not exceed the standard; if the weight of moisture attached to the blades exceeds the standard, the detection plate 8 will drive the vertical block 13 to move vertically downward, and then the impact block 12 can first act on the bell 15 and then act on the iron sheet 14. Since the sounds made by the bell 15 and the iron sheet 14 are different, the workers can conclude that the weight of moisture attached to the blades being inspected this time exceeds the standard by distinguishing the different sounds.

[0065] During the period when the impact block 12 acts on the iron sheet 14, the iron sheet 14 will first make a sound, and then under the action of the impact block 12, it moves toward the position where the slider 18 is located, and then the slider 18 hits the iron sheet 14 to make a second sound, thereby enhancing the effect of the sound emitted by the iron sheet 14 and improving the utilization rate of the sound emitted by the iron sheet 14. Since the impact block 12 can make reciprocating motion, the combined action of the slider 18 and the impact block 12 can increase the frequency of the impact on the iron sheet 14, making the sound emitted by the iron sheet 14 faster and louder, thereby enhancing the inspection effect of the moisture content of the blades and improving the efficiency of the inspection of the moisture content of the blades.

[0066] Under the combined action of the iron sheet 14 and the third spring, the slider 18 reciprocates, while the movable block 21 moves synchronously. During this motion, the movable block 21 continuously strikes the copper sheet 20, causing it to emit a sound. This mixing of the sound produced by the iron sheet 14 and the sound produced by the copper sheet 20 creates reverberation. This propagation of reverberation provides a more effective warning, allowing workers to more accurately detect the source of the sound and quickly determine if the moisture content of the blade being inspected exceeds the standard, further improving the efficiency of moisture testing.

[0067] Under the combined action of the movable block 21 and the fourth spring, the copper plate 20 reciprocates toward the location of the sound hole 2. During this movement, the copper plate 20, through contact with the sound hole 2, can adjust the amount of sound transmitted through the sound hole 2, causing the sound to fluctuate in volume. This adjustment of the sound volume increases the worker's sensitivity to sound, thereby comprehensively enhancing the effectiveness of leaf moisture testing.

[0068] During the rotation of shaft 36, shaft 36 drives shaft 24 via belt 41. During the rotation of shaft 24, cam 40 rotates synchronously. During the rotation of cam 40, when the raised portion of cam 40 contacts power block 50, power block 50 drives auxiliary block 23 toward the location of iron sheet 14, compressing the seventh spring. When the raised portion of cam 40 no longer contacts power block 50, the seventh spring returns auxiliary block 23 to its original position. Consequently, auxiliary block 23 reciprocates toward the location of iron sheet 14.

[0069] During the period when the impact block 12 impacts the iron sheet 14, the cooperation between the auxiliary block 23 and the impact block 12 enables the impact block 12 and the auxiliary block 23 to alternately impact the iron sheet 14, thereby making the frequency of the sound emitted by the iron sheet 14 higher and the sound emitted louder, ensuring that the sound emitted by the iron sheet 14 has a better propagation effect and a longer propagation distance, ensuring that the workers can receive the information that the water content attached to the blades on the detection plate 8 is too high.

[0070] As the rotating shaft 24 rotates, the brush block 25 moves synchronously. The bristle layer 26 also moves during this movement. During this movement, the bristle layer 26 removes dust clogged within the sound hole 2, preventing it from clogging the hole 2 and interfering with sound transmission. This enhances the sound transmission effect through the sound hole 2 and ensures that the sound is more fully and comprehensively transmitted to the outside world through the sound hole 2.

[0071] During the vertical reciprocating motion of the lifting block 27, the long block 31 moves synchronously with the lifting block 27. During its motion, the long block 31 drives the first electrode sheet 32 toward the position of the second electrode sheet 33 until the first electrode sheet 32 and the second electrode sheet 33 are in contact, at which point the warning light 34 is energized. When the warning light 34 is energized, it signals that the brush roller 28 has completed its cleaning work. If the sound emitted at this time is that of the bell 15, it indicates that the blade moisture content is within a controllable range. If the sound emitted at this time is a reverberation of the iron sheet 14 and the copper sheet 20, it indicates that the blade moisture content test has failed. In other words, with the assistance of the warning light 34, workers can better judge the progress and results of the blade moisture content test, thereby improving the quality of the blade moisture content test.

[0072] In summary, if the weight of the water content attached to the blades is within the specified value, the worker will be notified by the warning light 34 and the bell 15. If the weight of the water content attached to the blades is above the specified value, the worker will be notified by the warning light 34, the iron sheet 14, and the copper sheet 20. This change allows workers to more quickly interpret the device's results on the water content attached to the blades, thereby enhancing the device's practicality.
