DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0031] Mulberry leaves are the dried leaves of the mulberry plant Morus alba L., which are generally used as the main food for silkworms and can also be used as traditional Chinese medicine. Both require cleaning after the mulberry leaves are picked to ensure their cleanliness. Conventional cleaning methods sometimes involve using water flow to impact the mulberry leaves and then draining and drying the cleaned mulberry leaves. This method separates each step and is undoubtedly time-consuming through draining and drying. Moreover, mulberry leaves generally have two sides. When the mulberry leaves are stacked together, the contact surfaces with each other are not thoroughly cleaned, resulting in poor cleaning effects. Therefore, this technical problem needs to be solved.

[0032] As Figures 1 - 8 shown, the present invention relates to a mulberry leaf cleaning device, including a frame 1, on which a tank body 2 is fixed. The tank body 2 has a feed door 3, a discharge door 4 and a housing 5. The housing 5 is fixed above the tank body 2 and communicates with it. A rotating shaft 6 is rotatably arranged in the tank body 2. A shaft hole 7 is formed in the rotating shaft 6. A screen box 8 is arranged outside the rotating shaft 6. The rotating shaft 6 and the screen box 8 are connected by a plurality of connecting mechanisms. A power unit and a wind power unit are arranged on the frame 1. The power unit cooperates with the rotating shaft 6. One end of the wind power unit is rotationally and sealingly cooperated with the shaft hole 7 through a rotary joint, and the other end of the wind power unit communicates with the housing 5.

[0033] With such a design, during use, open the feed door 3. In the initial state, the mouth of the screen box 8 is aligned with the feed door 3, and the inside of the tank body 2 is filled with water. Then, the mulberry leaves can be put into the inside of the screen box 8. Close the feed door 3. Drive the rotating shaft 6 to slowly rotate counterclockwise in the direction close to the discharge door 4 through the power unit. During the rotation, generate wind power through the wind power unit and transport the wind power into the shaft hole 7 in the rotating shaft 6, and then transport it into the inside of the screen box 8 through the connecting mechanism. The connecting mechanism blows the mulberry leaves from below, causing the dust on the mulberry leaves to escape from the screen box 8 and be placed in the tank body 2 after vibration. At the same time, the other end of the wind power unit sucks through the housing 5, causing a negative pressure in the housing 5. Under the action of the negative pressure, the dust in the tank body 2 enters the inside of the housing 5, thereby realizing the circulating flow of the wind power and removing the dust in the circulation during the flow process.

[0034] As the rotating shaft 6 rotates, when the sieve box 8 flips, the mulberry leaves inside it also flip accordingly, and the air outlet end of the connecting mechanism also switches accordingly. At this time, the switched connecting mechanism blows the other side of the mulberry leaves, and the principle is the same as the above description, so it will not be elaborated too much here, thus achieving a comprehensive cleaning of the mulberry leaves. The above processes are all located in the upper half of the tank body 2, and dust removal of the front and back sides of the mulberry leaves is achieved through the impact of air flow.

[0035] Again, as the rotating shaft 6 rotates, the sieve box 8 is placed in the water in the lower half of the tank body 2. The principle is similar to the previous description. The difference is that due to the presence of water, the mulberry leaves in the sieve box 8 are evenly distributed, and with the flow of air, the water flow is made to flow to wash the mulberry leaves. Since the sieve box 8 also flips the mulberry leaves during the rotation in the lower half of the tank body 2, the front and back sides of the mulberry leaves can be cleaned by the way of water flow washing.

[0036] Again, as the rotating shaft 6 rotates, the sieve box 8 leaves the water surface and gradually approaches the feed door 3. At this time, the heating function of the fan 23 is turned on, and the mulberry leaves in the sieve box 8 are dried by hot air. Then, as the rotating shaft 6 rotates, the sieve box 8 gradually approaches the discharge door 4. During this period, the mulberry leaves in the sieve box 8 will flip, so the front and back sides of the mulberry leaves can also be dried during drying. When the box opening of the sieve box 8 is aligned with the discharge door 4, the movement stops, and then the discharge door 4 can be opened to take out the mulberry leaves.

[0037] It should be noted that the gap between the sieve box 8 and the tank body 2 is small, while the size of the mulberry leaves is large, so the mulberry leaves will not fall off from the gap. And when the sieve box 8 leaves the water, the rotating shaft 6 can be temporarily stopped to allow the mulberry leaves in the sieve box 8 to drain water.

[0038] Specifically, the connecting mechanism includes a connecting rod 9, a switching member, two connecting pipes 10 and two square pipes 11. The rotating shaft 6 is fixed to the sieve box 8 through the connecting rod 9. A horizontal hole 12 and a vertical hole 13 that are perpendicular to each other and communicate are formed inside the connecting rod 9. The shaft hole 7 communicates with the sieve box 8 through the horizontal hole 12. The switching member is movably arranged in the vertical hole 13. The two ends of the vertical hole 13 are respectively communicated with the two square pipes 11 through the two connecting pipes 10. The two square pipes 11 are respectively fixed on both sides of the sieve box 8 and communicate with it. Pressure relief valves 14 are fixed at the connection between the horizontal hole 12 and the sieve box 8 and at the connection between the two square pipes 11 and the sieve box 8.

[0039] The switching member includes a hollow column 15. An upper opening 16, a middle opening 17 and a lower opening 18 that communicate with each other are formed on the hollow column 15 from top to bottom in sequence. The aperture sizes at both ends of the vertical hole 13 are larger than the aperture size in the middle part.

[0040] With such a design, the wind enters the horizontal hole 12 in the connecting rod 9 through the shaft hole 7 in the rotating shaft 6. In the initial state, the hollow column 15 abuts against the inner bottom wall of the vertical hole 13 under its own gravity. At this time, a part of the wind is transmitted to the sieve box 8 through the horizontal hole 12, the middle opening 17, and the pressure relief valve 14 on the horizontal hole 12. At the same time, another part of the wind is transmitted to the square pipe 11 below through the horizontal hole 12, the middle opening 17, the lower opening 18, and the connecting pipe 10 below, and is transmitted to the sieve box 8 through the pressure relief valve 14 in the square pipe 11, so as to realize the blowing of the mulberry leaves from the height direction and the width direction of the sieve box 8, making the contact area between the mulberry leaves and the wind larger. The height direction of the sieve box 8 is the same as the axis direction of the connecting rod 9;

[0041] When the sieve box 8 rotates with the rotating shaft 6 to turn the mulberry leaves inside it, at this time the hollow column 15 also switches accordingly. The principle is similar to the above. A part of the wind is transmitted to the sieve box 8 through the horizontal hole 12, the middle opening 17, and the pressure relief valve 14 on the horizontal hole 12; the difference is that another part of the wind is transmitted to the other square pipe 11 through the horizontal hole 12, the middle opening 17, the upper opening 16, and another connecting pipe 10.

[0042] It should be noted that the pressure relief valve 14 can be replaced by a breathable valve or a one-way valve; the wind power unit can work intermittently so that the mulberry leaves can shake up and down inside the sieve box 8. When the sieve box 8 is located in the upper half of the tank body 2, it can accelerate the separation of dust from the mulberry leaves or accelerate the drying rate of the mulberry leaves.

[0043] Specifically, the feed door 3 and the discharge door 4 are distributed on both sides of the tank body 2. Among them, the feed door 3 is located above the horizontal diameter line of the tank body 2, and the discharge door 4 is located below the horizontal diameter line of the tank body 2; a guide plate 19 is fixed on the tank body 2, and the guide plate 19 is located below the discharge door 4.

[0044] With such a design, the inclined feed door 3 is convenient for the staff to put the mulberry leaves into the inside of the sieve box 8, and for the inclined discharge door 4, when the sieve box 8 is aligned with the discharge door 4, by opening the discharge door 4, the wind discharged through the connecting mechanism can accelerate the discharging process of the mulberry leaves in the sieve box 8, so that the mulberry leaves are discharged through the guide plate 19.

[0045] Specifically, a plurality of sieve holes are opened on both sides of the sieve box 8 and on the side close to the inside of the rotating shaft 6. After a plurality of orifice plates 20 are fixed in the sieve box 8, a plurality of cleaning chambers 21 are formed through the plurality of orifice plates 20.

[0046] With such a design, it is convenient for the dust to escape or accelerate the separation of moisture through a plurality of sieve holes; and through a plurality of cleaning chambers 21, the mulberry leaves can be placed separately, avoiding excessive accumulation of the mulberry leaves together, so as to ensure the cleaning effect on the mulberry leaves.

[0047] Specifically, a plurality of dust suction holes 22 are formed in the tank body 2, and the tank body 2 is communicated with the housing 5 through the plurality of dust suction holes 22.

[0048] With such a design, it is convenient for dust to enter the interior of the housing 5 through the dust suction holes 22.

[0049] Specifically, the wind power unit includes a blower 23 with a heating function and a dust filter 24. Both the blower 23 and the dust filter 24 are fixed on the frame 1. One end of the blower 23 is rotationally and sealingly fitted with the shaft hole 7 through a rotary joint, and the other end of the blower 23 is communicated with the housing 5 through the dust filter 24.

[0050] With such a design, wind power is generated by the blower 23, and the dust in the wind circulation process is filtered by the dust filter 24 to ensure the cleanliness of the air flow.

[0051] Specifically, the power unit includes a servo motor 25, a gearbox 26 and a large pulley 27. Both the servo motor 25 and the gearbox 26 are fixed on the frame 1. The large pulley 27 is fixed on the rotating shaft 6. The driving pulley on the servo motor 25 and the driven pulley on the gearbox 26 are connected by a vertical transmission belt, and the small pulley on the gearbox 26 and the large pulley 27 on the rotating shaft 6 are connected by an inclined transmission belt.

[0052] With such a design, the driven pulley on the gearbox 26 is moved by the driving pulley on the servo motor 25 and the vertical transmission belt. Under the action of the gearbox 26, the small pulley and the inclined transmission belt drive the large pulley 27 on the rotating shaft 6 to rotate, thereby realizing the driving operation of the rotating shaft 6.

[0053] Considering that the water flow in the tank body 2 will contain more foreign matters after use, in order to ensure the cleaning effect on mulberry leaves and save water resources, a water circulation unit is provided on the frame 1. The water circulation unit includes a pump body 28, a water tank 29 and a circulation filter 30. The pump body 28, the water tank 29 and the circulation filter 30 are all fixed on the frame 1. One end of the pump body 28 is communicated with the tank body 2, the other end of the pump body 28 is communicated with the water tank 29, and the water tank 29 is communicated with the tank body 2 through the circulation filter 30; and electromagnetic valves are fixed at the connection between the circulation filter 30 and the tank body 2 and at the connection between the pump body 28 and the tank body 2.

[0054] With such a design, during use, the two electromagnetic valves are opened, and the water in the water tank 29 is conveyed into the interior of the tank body 2 by the pump body 28. Then the water flow in the tank body 2 flows into the interior of the circulation filter 30, and the water is filtered by the circulation filter 30 to remove foreign matters and dirt, ensuring the flushing effect of the water on the mulberry leaves. The filtered water returns to the interior of the water tank 29 again, thereby realizing the recycling of water.
