[0040] As a further implementation scheme of the present invention, the air inlet and air outlet of the fan 4 are adjustable.

[0041] In a specific implementation, the reverse cleaning of the inclined filter 16 can be achieved by adjusting the air inlet and outlet ends of the fan 4 .

[0042] Working principle of the present invention: When the present invention is in use, the dried mulberry leaves are first placed in the inner cylinder 3, and then the motor 13, the fan 4 and the heating plate 15 are turned on. At this time, the fan 4 draws air from the inner cylinder 3, and the heating plate 15 transfers heat to the collection box 8 to achieve the purpose of heating the collection box 8. After the motor 13 is turned on, the cutting knife 23 and the scraper 27 are driven to rotate through the rotating shaft 17. During the rotation process, the cutting knife 23 can effectively cut the mulberry leaves.

[0043] After the fan 4 is turned on, air will be extracted from the interlayer 21 through the air outlet pipe 5. After the air in the interlayer 21 is extracted, air will be extracted from the inside of the inner tube 3 through the sieve hole 22 for replenishment, so as to realize the flow of air. In the process of air flow, the mulberry leaf fragments cut by the cutting knife 23 will be extracted, and then the mulberry leaf fragments will pass through the sieve hole 22 into the interlayer 21, and then enter the air outlet pipe 5. After entering the air outlet pipe 5, the mulberry leaf fragments will contact the inclined filter screen 16 under the drive of the air, and the inclined filter screen 16 will cause the mulberry leaf fragments to generate a downward component force, and then fall into the collection box 8 under the action of the component force and gravity, and the mulberry leaf fragments are effectively collected by the collection box 8.

[0044] During the operation of the fan 4, the motor 13 will also drive the connecting rod 24 to rotate through the rotating shaft 17, and then the connecting rod 24 will drive the scraper 27 to rotate. During the rotation, the scraper 27 will effectively scrape the sieve hole 22, and then move the uncut mulberry leaves moving with the airflow toward the direction close to the cutting knife 23. On the one hand, it can make the uncut mulberry leaves contact with the cutting knife 23, thereby improving the cutting rate of the mulberry leaves. On the other hand, it can also prevent the mulberry leaves from clogging the sieve hole 22, resulting in the cut mulberry leaves being unable to be discharged from the sieve hole 22, thereby causing the mulberry leaves to be over-broken.

[0045] In the process of cutting mulberry leaves, the moisture in the mulberry leaves will penetrate at the incision, and then a certain amount of liquid will appear at the cutting edge of the mulberry leaf pieces, the main components of which are water and inorganic salts. However, in the subsequent process of feeding silkworms, the mulberry leaves often have certain requirements for the humidity of the mulberry leaves. The mulberry leaves cannot be too wet. The airflow driven by the fan 4 is used for discharge, which is conducive to using the flow of airflow to accelerate the evaporation of the liquid at the cutting wound of the mulberry leaves, which is conducive to avoiding the mulberry leaves from being too wet, thereby improving the degree of dryness of the mulberry leaves. After heating, the heating plate 15 under the collection box 8 will increase the temperature of the collection box 8, thereby accelerating the continuous evaporation of the moisture in the mulberry leaf pieces entering the collection box 8, further realizing the drying of the mulberry leaf pieces, which is conducive to avoiding the mulberry leaf pieces from being too wet.

[0046] After the blower 4 near the side of the support 6 is turned on, on the one hand, the mulberry leaves cut in the inner cylinder 3 will be discharged, and on the other hand, the output end of the blower 4 will output airflow into the empty slot, and then the airflow will be discharged through the exhaust hole 11. In the process of the airflow being discharged through the exhaust hole 11, the frame 7 placed above the support 6 can be blown, and by placing the mulberry leaves that have not been cut in the frame 7, before the mulberry leaves are cut, the mulberry leaves are pre-dried by the airflow, which is conducive to avoiding the situation that the mulberry leaves are too wet due to the presence of moisture on the surface of the mulberry leaves, and further ensuring the drying of the mulberry leaves. By placing the mulberry leaves after cleaning and preliminary drying in the frame 7, the drying of the mulberry leaves is realized by the flow of airflow, while ensuring that the mulberry leaves are clean, the drying of the mulberry leaves can also be ensured. Through the setting of the mesh 31, it is conducive to avoiding the situation that the mulberry leaves are blown away by the airflow.

[0047] After the fan 4 on the side away from the support 6 is turned on, in addition to being able to discharge the cut mulberry leaves in the inner tube 3, it also outputs air flow toward the connecting air pipe 9, thereby increasing the air pressure in the hollow tube 14. By using the heating plate 15 located below the fan 4, the gas in the chamber of the hollow tube 14 located on the side of the air pressure plate valve 12 away from the support 6 can be heated, so that the temperature of the gas rises. Before the air pressure plate valve 12 is opened, the gas entering the hollow tube 14 will enter the sleeve 19 through the air inlet pipe 26, and then enter the built-in tube 18 through the through hole 20, and finally blow onto the cutting knife 23 through the atomizing nozzle 28 located at the top of the rotating shaft 17.

[0048] By guiding the airflow through the atomizing nozzle 28, on the one hand, the mulberry leaf fragments adhering to the cutting knife 23 can be blown off, which is beneficial to avoid the mulberry leaf fragments adhering to the cutting knife 23. On the other hand, the heated airflow can also be used to heat the cutting knife 23, which is beneficial to use the temperature of the cutting knife 23 to quickly evaporate the moisture on the wound of the mulberry leaf when the cutting knife 23 cuts the mulberry leaf. At the same time, the airflow will also blow on the mulberry leaf that has just been cut, which can accelerate the evaporation of moisture at the cut wound of the mulberry leaf, improve the drying efficiency of the mulberry leaf, and help avoid the mulberry leaf from becoming too wet due to excessive outflow of internal liquid, which is not conducive to the subsequent consumption of mulberry silkworms.

[0049] With the continuous operation of the blower 4 away from the support 6 side, the air pressure in the chamber of the air pressure plate valve 12 on the side away from the support 6 inside the hollow tube 14 will gradually increase. When the air pressure increases to the preset pressure value of the air pressure plate valve 12, the air pressure plate valve 12 will open. After opening, the air pressure plate valve 12 will allow the gas in the hollow tube 14 to enter the riser 10, and then blow on the mulberry leaves placed inside the frame 7 through the empty groove and the exhaust hole 11, further drying the mulberry leaves, and the gas passing through the hollow tube 14 will be heated by two heating plates 15, so that the temperature of the airflow is increased to a certain extent, which is conducive to accelerating the evaporation of the moisture on the surface of the mulberry leaves, and further ensuring the reduction of the moisture of the mulberry leaves before cutting. The two blowers 4 can effectively dry the mulberry leaves, ensuring that the surface of the mulberry leaves is dry before cutting.

[0050] After the mulberry leaves in the inner cylinder 3 are cut, the dried mulberry leaves in the frame 7 are placed in the inner cylinder 3 for continuous cutting. New mulberry leaves can also be added to the frame 7 to dry the surface of the new mulberry leaves.

[0051] After all the mulberry leaves have been cut, the air inlet and outlet ends of the fan 4 are changed by controlling the fan 4 so that the fan 4 draws air from the empty slot. Then, the external water pump is turned on, and the external water pump delivers water to the sleeve 19 through the water inlet pipe 25. After the water enters the sleeve 19, it is sprayed through the built-in tube 18 and the atomizing nozzle 28. On the one hand, the cutting knife 23 and the inner wall of the inner tube 3 can be effectively flushed, which is beneficial to prevent the pigment in the mulberry leaves from condensing in the inner tube 3. On the other hand, the water flow sprayed by the atomizing nozzle 28, while keeping the motor 13 working, can also enable the motor 13 to drive the connecting rod 24 and the scraper 27 to continue to rotate, and the inner bottom wall panel of the inner tube 3 is cleaned by the connecting rod 24, and the sieve hole 22 is cleaned by the scraper 27, so as to improve the cleanliness of the inner tube 3.

[0052] After the fan 4 changes its air inlet and outlet, the fan 4 will blow air toward the inclined filter 16 to achieve reverse cleaning of the inclined filter 16 and blow off the mulberry leaf fragments stuck on the inclined filter 16. It should be noted that after the mulberry leaves are cut, the collection box 8 is removed, and in the process of the water pump conveying water to the inner cylinder 3, as more and more water is in the inner cylinder 3, the water will enter the interlayer 21 through the sieve hole 22, and then enter the air outlet pipe 5, and fall on the bottom plate 1 through the discharge port.

[0053] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention.
