[0055] The present invention will be further described below with reference to the accompanying drawings:

[0056] This embodiment:

[0057] Please see Figure 1-10In this embodiment: a medicinal herb cleaning machine includes: a cleaning component, a feeding component, and a dust removal device.

[0058] The cleaning component is used to clean the medicinal materials; the cleaning component includes: sieve cylinder 5, which is used to separate debris and medicinal materials.

[0059] In this embodiment, by operating the cleaning component, the cleaning component will cause the sieve cylinder 5 to rotate rapidly, thereby causing the medicinal materials inside to rotate. The surface of the sieve cylinder 5 is provided with holes, which allows the debris and dust that have detached from the medicinal materials to leak out and be separated.

[0060] The feeding assembly is connected to the sieve cylinder 5 and is used to feed the medicinal materials into the sieve cylinder 5.

[0061] In this embodiment, the feeding component can continuously feed the medicinal materials into the sieve cylinder 5, thereby improving the cleaning efficiency.

[0062] The dust removal device is located on the outside of the screen cylinder 5 and is fixedly connected to the screen cylinder 5. It is used to remove the dust after cleaning.

[0063] In this embodiment, by operating the dust removal device, the leaked debris and dust will be collected and cleaned, while preventing dust from coming into contact with the user, achieving sealed dust removal during the cleaning process, which is convenient to use.

[0064] The herb cleaning machine also includes: a support frame 1; the support frame 1 consists of a shell, two sets of crossbars and a movable frame, the two sets of crossbars and the movable frame are located on one side of the shell, and the bottom end of the movable frame is slidably connected to the crossbars.

[0065] In this embodiment, by pushing the movable frame, the movable frame can be moved along the crossbar in a direction away from the outer casing.

[0066] like Figure 3 and Figure 6 As shown, the dust removal device includes: a dustproof sleeve 14, a cleaning auger 15, and a fan 16.

[0067] The dustproof sleeve 14 is fitted onto the outer wall of the screen cylinder 5, and the outer wall of the dustproof sleeve 14 is fixedly connected to the movable frame.

[0068] In this embodiment, the dustproof sleeve 14 can prevent the generated dust from coming into contact with the user; when the mobile frame moves, it can move the dustproof sleeve 14; a box door is installed at the bottom of the dustproof sleeve 14, and this box door is in the same vertical plane as the fan 16, which can clean up larger debris.

[0069] The cleaning auger 15 is positioned between the screen cylinder 5 and the dustproof sleeve 14, and is wrapped around the outer surface of the screen cylinder 5.

[0070] In this embodiment, when the screen cylinder 5 rotates, it will drive the cleaning auger 15 to rotate synchronously, and the cleaning auger 15 will push the debris from other locations to the location of the blower 16.

[0071] The input end of the fan 16 is connected to the inside of the dustproof sleeve 14; the output end of the fan 16 is connected to the outside.

[0072] In this embodiment, the fan 16 cleans up the generated dust and small debris to prevent the dust from coming into contact with the user.

[0073] During dust removal, as the screen cylinder 5 rotates, the cleaning auger 15 rotates synchronously. The cleaning auger 15 pushes debris from other locations to the location of the fan 16. At this time, the fan 16 is started. Due to the setting of the dustproof sleeve 14, dust can be prevented from spreading outward. The fan 16 can suck away dust and smaller debris, while larger debris is collected and cleaned through the box door below the dustproof sleeve 14, thus achieving the dust removal function.

[0074] like Figure 4 and Figure 5 As shown, the feeding assembly includes: a feeding channel 2, a feeding auger 3, and a drive motor 4.

[0075] Specifically, the feed channel 2 is located inside the outer shell, and one end of the feed channel 2 is connected to the screen cylinder 5, while the other end is connected to the outside.

[0076] In this embodiment, the medicinal materials enter the sieve cylinder 5 through the feeding channel 2.

[0077] The feeding auger 3 is located at one end of the feeding channel 2, and one end of the feeding auger 3 passes through the corresponding position of the feeding channel 2 and is rotatably connected to the feeding channel 2; the output end of the drive motor 4 is fixedly connected to the end of the feeding auger 3 that passes through the feeding channel 2.

[0078] In this embodiment, the model of the drive motor 4 is selected according to actual needs, as long as it meets the working conditions; when the drive motor 4 is running, the output end of the drive motor 4 drives the feeding auger 3 to rotate, and the feeding auger 3 can send the medicinal materials into the sieve cylinder 5.

[0079] like Figure 4 and Figure 6 As shown, the cleaning assembly also includes: a first transmission assembly 6, multiple sets of limiting members 7, a gearbox 8, a second transmission assembly 9, and multiple sets of limiting wheels 13.

[0080] The first transmission component 6 consists of a first gear and a second gear, with the edge of the first gear meshing with the second gear; a notch is provided on one side of the first gear so that one end of the screen cylinder 5 can be inserted into the notch.

[0081] In this embodiment, by inserting the sieve cylinder 5 into the notch of the first gear, the first gear can drive the sieve cylinder 5 to rotate; and when the moving frame moves, it can drive the sieve cylinder 5 to move, so that the sieve cylinder 5 disengages from the notch.

[0082] An annular groove is provided on the other side of the first gear; one end of each set of limiting members 7 is set in the annular groove and is slidably connected to the first gear through the annular groove; the other end of the limiting member 7 is fixedly connected to the outer shell.

[0083] In this embodiment, the limiting member 7 can support the first gear, preventing it from falling off when the screen cylinder 5 separates from the first gear, and also supporting the rotation of the first gear.

[0084] The output shaft of the gearbox 8 is fixedly connected to the shaft of the second gear; the second transmission assembly 9 consists of a chain and two sets of sprockets, with the edges of the two sets of sprockets meshing with the chain; the shaft of one set of sprockets is fixedly connected to the input shaft of the gearbox 8; and the shaft of the other set of sprockets is fixedly connected to the output end of the drive motor 4.

[0085] In this embodiment, when the output end of the drive motor 4 rotates, it can simultaneously drive the sprocket connected to it to rotate. This sprocket drives another sprocket to rotate through the chain, and the other sprocket drives the second gear to rotate through the reduction of the gearbox 8.

[0086] Multiple sets of limiting wheels 13 are located at the edge of the screen cylinder 5 away from the outer shell and are in contact with the screen cylinder 5.

[0087] In this embodiment, the limiting wheel 13 will restrict the screen cylinder 5 to the middle position, but will not restrict the rotation of the screen cylinder 5.

[0088] like Figure 8 As shown, the cleaning assembly also includes: a rotating rod 17, multiple sets of extension components, and a baffle assembly.

[0089] Specifically, one end of the rotating rod 17 is fixedly connected to the end of the feeding auger 3 that is away from the drive motor 4.

[0090] In this embodiment, when the feeding auger 3 rotates, it will drive the rotating rod 17 to rotate synchronously.

[0091] Multiple extension components are disposed on the outer surface of the rotating rod 17.

[0092] In this embodiment, the extension component is used to increase the number of impacts on the medicinal materials during the cleaning process, thereby improving cleaning efficiency.

[0093] The material blocking assembly is located at the end of the screen cylinder 5 away from the outer shell and is used to control the material discharge.

[0094] In this embodiment, the discharge speed is controlled by controlling the distance between the baffle assembly and the screen cylinder 5.

[0095] like Figure 8 As shown, the material stop assembly includes: a material stop plate 12, a threaded rod 10, and a handle 11.

[0096] The outer diameter of the baffle plate 12 is larger than the inner diameter of the screen cylinder 5; one end of the threaded rod 10 passes through the corresponding position of the baffle plate 12 and is threadedly connected to the baffle plate 12.

[0097] In this embodiment, when the threaded rod 10 rotates, the baffle plate 12 will move horizontally, thereby controlling the distance between the baffle plate 12 and the screen cylinder 5.

[0098] The other end of the threaded rod 10 passes through the corresponding position of the movable frame and is rotatably connected to the movable frame; the handle 11 is fixedly connected to one end of the threaded rod 10 that passes through the movable frame.

[0099] In this embodiment, the threaded rod 10 is rotated by rotating the handle 11.

[0100] When it is necessary to control the discharge speed, the screw rod 10 is rotated by turning the handle 11. The screw rod 10 will cause the baffle plate 12 to move horizontally, thereby controlling the distance between the baffle plate 12 and the screen cylinder 5. When the distance is larger, the discharge speed is faster; conversely, when the distance is smaller, the discharge speed is slower.

[0101] like Figure 7 As shown, each extension assembly includes: a cleaning rod 18, a slider 19, and an extension sleeve 20.

[0102] Specifically, a spiral slide is provided on the outer surface of the cleaning rod 18; one end of the slider 19 is located in the spiral slide and is slidably connected to the cleaning rod 18 through the spiral slide.

[0103] In this embodiment, the slider 19 can slide along the spiral slide, thereby changing the position of the slider 19.

[0104] The extension sleeve 20 is fitted onto the surface of the cleaning rod 18 and is fixedly connected to the other end of the slider 19.

[0105] In this embodiment, by rotating the extension sleeve 20, the extension sleeve 20 drives the slider 19 to rotate, and the slider 19 slides along the spiral slide, thereby causing the extension sleeve 20 to move while rotating.

[0106] When extension is required, by rotating the extension sleeve 20, the extension sleeve 20 will drive the slider 19 to rotate, and the slider 19 will slide along the spiral slide, so that the extension sleeve 20 moves along the surface of the cleaning rod 18 while rotating, thereby extending the length of the cleaning rod 18, which can clean the medicinal materials when there are few medicinal materials.

[0107] After rotation, the position of the extension sleeve 20 is not restricted and it easily returns to its original position.

[0108] To address the aforementioned issues, this embodiment proposes an implementation method in which the herb cleaning machine further includes a limiting device; the limiting device is located inside the rotating rod 17 and is used to restrict the rotation of the extension sleeve 20.

[0109] In this embodiment, as Figure 9 and Figure 10 As shown, the limiting device includes: multiple sets of limiting rods 21, multiple sets of wedges 22, connecting rods 23, multiple sets of elastic elements 24, and moving rods 25.

[0110] In this case, one end of each set of limiting rods 21 passes through the corresponding position of the cleaning rod 18 and extends into the extension sleeve 20.

[0111] In this embodiment, the rotation of the extension sleeve 20 is restricted by inserting the limiting rod 21 into the extension sleeve 20, thereby restricting the position of the extension sleeve 20.

[0112] Each set of wedges 22 is slidably connected to the other end of the limiting rod 21.

[0113] In this embodiment, a slide rail and a protrusion are provided at the connection between the wedge block 22 and the limiting rod 21, and the contact surface is an inclined surface, which can ensure that the wedge block 22 and the limiting rod 21 are always in contact; when the wedge block 22 moves horizontally, it will cause the limiting rod 21 to move vertically.

[0114] The connecting rod 23 is fixedly connected to multiple sets of wedges 22.

[0115] In this embodiment, when the connecting rod 23 moves, it will simultaneously drive multiple sets of wedges 22 to move.

[0116] One end of the elastic element 24 is fixedly connected to the connecting rod 23, and the other end can be inserted into the inner wall of the rotating rod 17; the moving rod 25 is fixedly connected to the elastic element 24.

[0117] In this embodiment, the elastic element 24 is formed by connecting a round rod and a hollow rod, and a spring is provided between the round rod and the hollow rod. When the elastic element 24 is inserted into the inner wall of the rotating rod 17, it will restrict the movement of the connecting rod 23.

[0118] When it is necessary to restrict the rotation of the extension sleeve 20, first pull the moving rod 25 towards the middle to compress the elastic element 24 and make the elastic element 24 separate from the inner wall of the rotating rod 17. At this time, the connecting rod 23 can be driven, and the connecting rod 23 simultaneously drives multiple sets of wedges 22 to move. The wedges 22 cause the limiting rod 21 to move vertically and insert the limiting rod 21 into the extension sleeve 20 to restrict the rotation of the extension sleeve 20.

[0119] like Figure 2 As shown, the herb cleaning machine also includes an electric push rod 26; the electric push rod 26 is disposed in the housing, and the output end of the electric push rod 26 is fixedly connected to the movable frame for pushing the movable frame to move.

[0120] In this embodiment, the model of the electric push rod 26 is selected according to actual needs, as long as it meets the working conditions.

[0121] Working principle:

[0122] When using this herb cleaning machine, before cleaning, first pull the moving rod 25 towards the center to compress the elastic element 24 and disengage it from the inner wall of the rotating rod 17. At this time, the connecting rod 23 can be driven, and the connecting rod 23 simultaneously drives multiple sets of wedges 22 to move. The wedges 22 cause the limiting rod 21 to move vertically, so that the limiting rod 21 disengages from the extension sleeve 20. Then, adjust the electric push rod 26 so that the output end of the electric push rod 26 pushes the moving frame to move along the crossbar. The moving frame will drive the entire dust removal device and the sieve cylinder 5 to move, so that the rotating rod 17 is exposed to the air.

[0123] At this time, by rotating the extension sleeve 20, the extension sleeve 20 will drive the slider 19 to rotate, and the slider 19 will slide along the spiral slide, so that the extension sleeve 20 moves along the surface of the cleaning rod 18 while rotating, so that the length of the cleaning rod 18 can be extended or retracted, which can be adjusted according to the amount of medicinal materials.

[0124] Subsequently, the electric push rod 26 is adjusted in the opposite direction, so that the entire dust removal device and screen cylinder 5 return to their original positions, and the limiting device is activated again to limit the extension sleeve 20.

[0125] Next, the medicinal materials are poured into the feeding channel 2. The rotation of the output end of the drive motor 4 drives the feeding auger 3 to rotate, sending the medicinal materials into the sieve cylinder 5. When the feeding auger 3 rotates, it drives the rotating rod 17 to rotate. The rotating rod 17 drives multiple sets of extension sleeves 20 to rotate clockwise. During this process, the output end of the drive motor 4 also drives the second transmission component 9 to rotate. The second transmission component 9 drives the first transmission component 6 to rotate through the gearbox 8. The first transmission component 6 causes the sieve cylinder 5 to rotate counterclockwise, using the reverse rotation to improve working efficiency.

[0126] As the screen cylinder 5 rotates, it drives the cleaning auger 15 to rotate synchronously. The cleaning auger 15 pushes debris from other locations to the location of the blower 16. At this time, the blower 16 is started. Due to the setting of the dustproof sleeve 14, dust can be prevented from spreading outward. The blower 16 can suck away dust and smaller debris, while larger debris is collected and cleaned through the box door below the dustproof sleeve 14, thus realizing the dust removal function and completing the use of this device.

[0127] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
