Description

Technical Field

[0001] This application relates to the field of processing technology for Isatis indigotica leaves, and specifically discloses a processing apparatus for Isatis indigotica leaves. Background Technology

[0002] It refers to the leaves of Isatis indigotica, a biennial herbaceous plant belonging to the Brassicaceae family. It is mainly produced in Hebei, Shaanxi, and Jiangsu provinces. Harvesting occurs 2-3 times during summer and autumn. It can be used fresh or dried for use in treating febrile diseases with excessive thirst, influenza, acute infectious hepatitis, bacillary dysentery, acute gastroenteritis, acute pneumonia, erysipelas, hematemesis, epistaxis, jaundice, dysentery, sore throat, canker sores, carbuncles, and boils.

[0003] Isatis leaf is effective against a variety of bacterial and viral diseases. In addition to treating the above-mentioned diseases, it has been widely used clinically in internal medicine, surgery, gynecology, pediatrics, stomatology, and ENT to treat infectious diseases such as acute infectious lymphocytosis, cholangitis, multiple boils, puerperal fever, mastitis, post-abortion infection, tonsillitis, peritonsillar abscess, and periodontitis, with varying degrees of effectiveness.

[0004] Currently, Isatis leaf is mainly used for two purposes: internal decoction and external application after crushing. Regardless of the application method, Isatis leaf needs to be cleaned. Generally, there are two cleaning methods: for small batches, manual washing; for large batches, ultrasonic cleaning and agitation cleaning. However, ultrasonic cleaning is not thorough, and agitation cleaning is too vigorous, causing the Isatis leaf to collide with the equipment's inner wall, easily damaging the leaf and causing juice to leak out, affecting its suitability for internal decoction and external application. Therefore, there is a lack of a gentle yet effective device suitable for large-scale Isatis leaf cleaning. In light of this, the inventor has made improvements to the Isatis leaf cleaning process, proposing a processing device for Isatis leaf. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that traditional cleaning devices can cause damage to the leaves of Isatis indigotica due to excessively vigorous cleaning, thereby affecting the quality of the leaves.

[0006] To achieve the above objectives, the present invention provides the following basic solution:

[0007] Processing equipment for Isatis tinctoria leaves, including

[0008] Housing assembly: includes an outer shell, an end cap connected to the outer shell, and several feed ports and water inlets provided on the end cap;

[0009] Raw material placement assembly: a connecting pipe connected to the feeding port and a placement box rotatably connected to the connecting pipe are set inside the outer shell. The placement box includes an upper gear disk, a lower gear disk and a protective frame for placing raw materials set between the upper gear disk and the lower gear disk. A gap is left between adjacent protective frames. The connecting pipe is fixed to the end cap.

[0010] Water flow agitation component: includes a motor located at the bottom of the housing, the output shaft of the motor passing through the housing and connected to a water flow stirring rod, the water flow stirring rod being provided with a rotation component for the rotation of the raw material placement component;

[0011] Water flow vibration assembly: includes an annular groove on the inner wall of the housing, a circular toothed disk that meshes with a lower gear disk and slides circumferentially within the annular groove, the circular toothed disk is provided with contact blocks, and the inner wall of the annular groove is provided with contact balls that can contact the contact blocks.

[0012] The principle and effect of this basic scheme are as follows:

[0013] 1. Compared with existing technologies, this device has a simple structure and ingenious design. First, this device is for the cleaning process of indigo leaves, which can achieve both gentle and thorough cleaning. In terms of the product itself, it is highly automated. The feeding personnel only need to put the corresponding cleaning material into the feeding port, and the water cleaning can be carried out by adding appropriate water through the water inlet. It is very simple to use.

[0014] 2. Compared with existing technologies, to avoid the problem of raw material damage caused by collisions during traditional raw material stirring and cleaning, this device is equipped with a raw material placement component and a water flow agitation component. The raw materials are fixed in a small area, and a water flow stirring rod is used to generate a stirring action to achieve a vortex effect, i.e., water flow agitation. The agitated water flow acts on the raw materials through a protective frame, causing the raw materials to not only rotate but also helping the water flow into the protective frame, thereby achieving water replacement. The water flow agitation component helps to remove particulate impurities attached to the raw materials, and the raw materials are cleaned under the action of water flow. Furthermore, because the raw materials are in a small area, the damage caused by collisions is greatly reduced.

[0015] 3. Compared with existing technologies, in order to improve the stirring effect, this device also has an independently set rotation component. The rotation component and the water flow agitation component are independent of each other and can be used independently or together. When the rotation component is used independently, the placement box rotates, which is equivalent to the raw material rotating. If the water flow agitation component is not activated at this time, it is equivalent to the raw material rotating and being washed in static water. When the water flow agitation component is activated, the rotation component is also activated. It is equivalent to the raw material being washed while rotating, under the effect of dynamic water, which will improve the washing effect of the raw material. Similarly, regardless of the washing effect mentioned above, since the raw material is in a small range, the damage caused by the collision of the raw material is greatly reduced.

[0016] 4. Compared with the existing technology, in order to further improve the cleaning effect, this device is also equipped with a water flow vibration component. The water flow vibration component needs to be used in conjunction with the rotation component. The water flow vibration component can make the shell vibrate. Since the water is inside the shell, when the shell vibrates, the vibration can be transmitted to the water, causing the water to vibrate, thereby improving the cleaning effect of the material.

[0017] 5. Compared with existing technologies, the water flow vibration component can be used in conjunction with the rotation component, and the water flow turbulence component can be used with or without the rotation component, thus diversifying the cleaning intensity and methods. This ensures the cleaning effect and cleaning intensity. In either mode, because the raw materials are in a small area, the damage caused by the collision of the raw materials is greatly reduced.

[0018] 6. Compared with existing technologies, this device reduces the size and intensity of the cleaning space compared with the traditional "large agitation" method. On the basis of reducing the size and intensity of the space, the cleaning intensity is increased. Moreover, compared with the traditional single agitation cleaning method, the cleaning method and cleaning effect of this device are superior to the traditional single agitation mode. In addition, this device solves the problem that the traditional cleaning device is too vigorous and will damage the indigo leaves, thus affecting the quality of the indigo leaves.

[0019] Furthermore, the connecting pipe extends out of the feeding port, and a retaining ring is provided on the inner ring of the feeding port to fix the connecting pipe. The retaining ring is used to connect to the inner ring of the feeding port and thus fix the connecting pipe, counteracting the weight of the connecting pipe.

[0020] Furthermore, the upper gear disk has a groove, and a rotary bearing is installed within the groove. The end of the connecting pipe furthest from the feed inlet is connected to the rotary bearing. Since the rotation of the connecting pipe is not required, but the rotation of the upper gear disk is, the rotary bearing is provided, allowing the upper gear disk to rotate while the connecting pipe remains stationary.

[0021] Furthermore, the protective frame includes a steel wire fixed between the upper and lower gear discs and a flexible protective sleeve wound around the outer circumference of the steel wire. The steel wire is circumferentially distributed between the upper and lower gear discs, and the gap between adjacent protective sleeves is small enough to prevent qualified raw materials from falling out. The flexible protective sleeve is used to contact the raw material, protecting it from impact damage and thus protecting its quality. The gap between adjacent protective sleeves mainly allows water to enter and exit, while also preventing qualified raw materials from falling out.

[0022] Furthermore, the motor output shaft passes through the housing and is connected to a mounting block. The mounting block has receiving grooves around its perimeter, and the water-fluid stirring rod is horizontally mounted in these grooves. The mounting block is positioned below the lower gear disc. The water-fluid stirring rod generates a vortex, which is created from the bottom and thus acts on the raw materials in the storage box.

[0023] Furthermore, a connecting component is provided between the water flow stirring rod and the rotating assembly to prevent the rotating assembly from rotating coaxially with the motor. This connecting component includes a sleeve, a first connecting groove and a second connecting groove disposed on the inner wall of the sleeve, and a first locking block and a second locking block mounted on the top of the mounting block. The first and second locking blocks are respectively installed in the second connecting groove and the first connecting groove. The rotating assembly includes a motor connected to the second locking block at its bottom, an extension rod coaxially connected to the motor, and a drive gear disk coaxially connected to the extension rod. The drive gear disk meshes with the upper gear disk. This allows the water flow stirring rod to rotate while the rotating assembly remains stationary, ensuring that the water flow stirring rod and the rotating assembly operate independently without interfering with each other.

[0024] Furthermore, a connecting block is provided on the top wall of the annular groove, and a spring is connected to the connecting block. The free end of the spring is connected to the contact ball, and the spring is inclined. The spring is used to reset the contact ball. The contact ball impacts the outer shell, causing the outer shell to vibrate slightly, which is then transmitted to the water to achieve water vibration.

[0025] Furthermore, it also includes a water pressure-assisted cleaning component, which comprises a sleeve and a piston connected to the sleeve, the piston being slidably connected within a connecting pipe. This achieves water pressure-assisted cleaning and improves the cleaning effect.

[0026] Furthermore, the outer diameter of the piston is equal to the inner diameter of the connecting pipe, and the end of the sleeve rod away from the piston is provided with a mesh-like anti-slip texture. This ensures that water pressure can be generated, thus ensuring the effectiveness of water pressure-assisted cleaning.

[0027] Furthermore, the housing is equipped with a control panel, which houses a PLC controller. Both the motor and the motor motor are electrically connected to the PLC controller. This results in a high degree of automation, simplifying manual operation. Attached Figure Description

[0040] Implementation, for example Figures 1-9 As shown:

[0041] Processing equipment for Isatis tinctoria leaves, including

[0042] Housing assembly: includes housing 1, end cap 5 connected to housing 1, and several feed ports 6 and water inlets 7 disposed on end cap 5;

[0043] Specifically: the end cap 5 is detachably connected to the outer casing 1. A boss is provided on the inner wall of the outer casing 1. The end cap 5 is placed on the boss and secured with screws to ensure stable installation. Figure 1 As shown, there are two feeding ports 6. Feeding ports 6 are used for manually adding indigo leaves, and water inlets 7 are used for manually adding clean water.

[0044] like Figure 2 As shown, the raw material placement assembly consists of a connecting pipe connected to the feeding port 6 inside the outer casing 1 and a placement box rotatably connected to the connecting pipe. The placement box includes an upper gear disk 14, a lower gear disk 16, and a protective frame 15 for placing raw materials disposed between the upper gear disk 14 and the lower gear disk 16. A gap is left between adjacent protective frames 15, and the connecting pipe is fixed to the end cap 5.

[0045] Specifically: the connecting pipe extends out of the feeding port 6, and a fixing ring 17 is provided on the inner ring of the feeding port 6 to fix the connecting pipe. The fixing ring 17 is used to connect to the inner ring of the feeding port 6 and thus fix the connecting pipe, counteracting the weight of the connecting pipe.

[0046] Specifically: such as Figure 2 and Figure 7 As shown, regarding the protective frame 15: The protective frame 15 includes a steel wire 1501 fixed between the upper gear disk 14 and the lower gear disk 16, and a flexible protective sleeve wound around the outer circumference of the steel wire 1501. The steel wire 1501 is circumferentially distributed between the upper gear disk 14 and the lower gear disk 16. The gap between adjacent protective sleeves is large enough to prevent qualified raw materials from falling out. The flexible protective sleeve is used to contact the raw materials, protecting them from impact damage and thus protecting their quality. Gaps are provided between adjacent protective sleeves, primarily for water to enter and exit, while also preventing qualified raw materials from falling out.

[0047] Specifically: Because the upper gear disk 14 needs to rotate, while the connecting pipe does not rotate with it, therefore, as Figure 2 and Figure 8 As shown, the upper gear disk 14 has a groove, and a rotating bearing 26 is installed in the groove. The lower end of the connecting pipe away from the feeding port 6 is connected to the rotating bearing 26. Since the rotation of the connecting pipe is not required, but the rotation of the upper gear disk 14 is required, the rotating bearing 26 is provided so that the connecting pipe remains stationary while the upper gear disk 14 rotates.

[0048] Water flow agitation component: includes a motor 3 located at the bottom of the housing 1, the output shaft of the motor 3 passes through the housing 1 and is connected to a water flow stirring rod 9, and the water flow stirring rod 9 is provided with a self-rotating component for the rotation of the raw material placement component;

[0049] like Figure 2 As shown, the output shaft of motor 3 passes through housing 1 and is connected to mounting block 8. Mounting block 8 has receiving grooves around its perimeter. Water flow stirring rod 9 is horizontally mounted in the receiving grooves. The mounting block 8 is located below the lower gear disk 16. The water flow stirring rod 9 generates a vortex, which is generated from the bottom and thus acts on the raw materials in the placement box.

[0050] To enable the independent use of the water flow turbulence component and the rotation component, such as Figure 2 and Figure 5 As shown, a connecting component 10 is provided between the water flow stirring rod 9 and the self-rotating assembly to prevent the self-rotating assembly from rotating coaxially with the motor 3. The connecting component 10 includes a sleeve, a first connecting groove and a second connecting groove disposed on the inner wall of the sleeve, and a first locking block 1003 and a second locking block 1001 mounted on the top of the mounting block 8. The first locking block 1003 and the second locking block 1001 are respectively installed in the second connecting groove and the first connecting groove. The self-rotating assembly includes a motor 11 connected to the bottom of the second locking block 1001, an extension rod 12 coaxially connected to the motor 11, and a drive gear disk 13 coaxially connected to the extension rod 12. The drive gear disk 13 meshes with the upper gear disk 14. This allows the water flow stirring rod 9 to rotate while the self-rotating assembly remains stationary, making the water flow stirring rod 9 and the self-rotating assembly independent and able to operate independently without interfering with each other.

[0051] When the mounting block 8 rotates, the first locking block 1003 rotates circumferentially in the second connecting groove, while the sleeve remains stationary, thus realizing the self-rotating component. The first locking block 1003 and the second locking block 1001 are installed in the second connecting groove and the first connecting groove respectively to improve their respective support force and thus counteract gravity.

[0052] Water flow vibration assembly: includes an annular groove 23 on the inner wall of the outer casing 1, a circular toothed disk 20 that slides around the circumference of the annular groove 23 and meshes with the lower gear disk 16, the inner ring of the circular toothed disk 20 is evenly provided with meshing teeth 21, the circular toothed disk 20 is provided with contact blocks 22, and the inner wall of the annular groove 23 is provided with contact balls 25 that can contact the contact blocks 22.

[0053] Specifically: such as Figure 3 and Figure 4 and Figure 9 As shown, a connecting block is provided on the top wall of the annular groove 23, and a spring 24 is connected to the connecting block. The free end of the spring 24 is connected to the contact ball 25, and the spring 24 is set at an angle. The spring 24 is used to reset the contact ball 25. The contact ball 25 impacts the outer shell 1, causing the outer shell 1 to vibrate slightly, and the vibration is transmitted to the water to realize the vibration of the water.

[0054] When the self-rotating component is activated, the upper gear disk 14 and the lower gear disk 16 rotate. Since this invention has two sets of upper gear disks 14 and lower gear disks 16, in order to avoid motion interference, only one of the upper gear disks 14 and the lower gear disk 16 needs to contact the circular gear disk 20. After the circular gear disk 20 rotates, the contact block 22 rotates around the annular groove 23. The contact block 22 will continuously contact the contact ball 25, causing the spring 24 to deform, which in turn causes the contact ball to hit the outer shell 1, causing the outer shell 1 to vibrate slightly.

[0055] like Figure 2 and Figure 6 As shown, it also includes a water pressure-assisted cleaning assembly, which includes a sleeve rod 18 and a piston 19 connected to the sleeve rod 18. The piston 19 can slide within the connecting pipe. This enables water pressure-assisted cleaning and improves the cleaning effect. The outer diameter of the piston 19 is equal to the inner diameter of the connecting pipe, and the end of the sleeve rod 18 away from the piston 19 is provided with a mesh-like anti-slip texture. This ensures that water pressure can be generated, thus ensuring the effectiveness of the water pressure-assisted cleaning.

[0056] like Figure 2 As shown, a support column 2 is provided on the bottom of the outer casing 1 to improve the stability of the device. A control panel 4 is located on the surface of the outer casing 1, and a PLC controller is installed inside the control panel 4. The motor 3 and the motor 11 are both electrically connected to the PLC controller. This design achieves a high degree of automation, simplifying manual operation.

[0057] Specific implementation process:

[0058] The leaves of Daqingye enter the placement box through the feeding port 6, and water is poured in through the water inlet 7. After a certain amount of water is filled, the water is turned off and the washing begins.

[0059] The first method involves starting the motor 3 separately and using the water flow stirring rod 9 to generate a stirring action, thereby achieving a vortex effect, i.e., the turbulence of the water flow. The turbulent water flow acts on the raw material through the protective frame 15, causing the raw material to not only rotate but also helping the water flow to be replaced within the protective frame 15.

[0060] The second method is to start the motor 11 separately. When the self-rotation component is used independently, that is, the placement box rotates, which is equivalent to the raw material rotating. If the water flow agitation component is not started at this time, it is equivalent to the raw material rotating and cleaning in static water, thus achieving cleaning.

[0061] The third method: starting motor 11 and starting motor 3 at the same time, for the raw materials, not only can they be cleaned by self-rotation, but they can also be cleaned in dynamic water, which improves the cleaning effect.

[0062] Fourthly, when the second method is activated, the water flow vibration component is also activated, using slight vibration to improve the cleaning effect.

[0063] The fifth method is water pressure assisted cleaning. The piston 19 on the sleeve rod 18 moves inside the connecting pipe. Due to the U-tube principle, a portion of the connecting pipe contains water. The movement of the piston 19 can push this water downwards. Specifically, the upper end of the connecting pipe has a large diameter, and the lower end has a small diameter. The small diameter must not affect the downward movement of the large indigo leaves. Due to the change from large to small diameter, when the piston 19 starts to move, it can generate a certain pressure. This pressure will act on the large indigo leaves between the protective frames 15, causing the large indigo leaves to tumble in the water, thereby improving the cleaning effect.

[0064] The fifth method can be combined with any one or more of the first, second, third, or fourth cleaning methods mentioned above, thereby making the cleaning methods more diverse.

[0065] This device solves the problem that traditional cleaning devices, due to their excessively vigorous cleaning, can damage the leaves of the Isatis indigotica, thus affecting their quality.

[0066] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
