[0034] When it is necessary to use the present device to screen and thread the Codonopsis pilosula, the user collects the Codonopsis pilosula collected from the cultivated land, and then the user arranges the Codonopsis pilosula of different thicknesses longitudinally and places them uniformly and gradually on the first feeding plate 9 and the second feeding plate 10 at a regular and quantitative manner, and the user starts the vibration motor on the lower side of the sub-screening plate 4, and the vibration motor drives the first feeding plate 9 and the second feeding plate 10 to vibrate together through the sub-screening plate 4 and the screening shell 3. Under the vibration of the first feeding plate 9 and the second feeding plate 10, the Codonopsis pilosula gradually passes through the gap between the first feeding plate 9 and the second feeding plate 10 and falls onto the sub-screening plate 4, and the Codonopsis pilosula that falls onto the sub-screening plate 4 gradually moves to the right due to the inclined sub-screening plate 4 and the vibration of the sub-screening plate 4.

[0035] In the process of the unified movement of Codonopsis pilosula of different thicknesses to the right, the Codonopsis pilosula of different thicknesses first contacts the smaller through holes evenly distributed on the sieve plate 4. If the maximum diameter of the Codonopsis pilosula is smaller than the finer through holes on the sieve plate 4, the Codonopsis pilosula falls onto the conveyor belt of the left conveying device 8 through the finer through holes on the sieve plate 4 and the first dispersion shell 5. The user starts the two conveying devices 8 at the same time. The conveyor belt of the left conveying device 8 conveys the Codonopsis pilosula that falls thereon to the left to the temporary storage room on the left side of the dispersion rack 2, while the Codonopsis pilosula with a maximum diameter larger than the finer through holes on the sieve plate 4 continues to move to the right until it moves to the coarser through holes on the sieve plate 4, and moves downward to the conveyor belt of the right conveying device 8 through the larger through holes on the sieve plate 4 and the second dispersion shell 6. The conveyor belt of the right conveying device 8 conveys the Codonopsis pilosula on it to the right to the temporary storage room on the right side of the dispersion rack 2. This is the Codonopsis pilosula screening step.

[0036] During the screening process of Codonopsis pilosula, the Codonopsis pilosula may be stuck in the baffle through-hole on the screening plate 4 due to its upper secondary roots. To ensure the normal screening of Codonopsis pilosula, the following operations need to be performed:

[0037] When screening Codonopsis pilosula, the user controls the two bidirectional lead screws 1101 to rotate together through external power at the same time. Taking the front bidirectional lead screw 1101 as an example, the bidirectional lead screw 1101 drives the fixed plate 1102, the first sliding frame 7 and the upper air bag to move to the left together through the thread, the first sliding frame 7 drives the air storage shell 1103 to move to the left, and the air storage shell 1103 drives the piston plate 1104, the fixed rod 1108 and the extrusion plate 1109 to move to the left synchronously, and as the extrusion plate 1109 and the first sliding frame 7 gradually move to the left, the air storage shell 1103 drives the piston plate 1104, the fixed rod 1108 and the extrusion plate 1109 to move to the left synchronously. When the first sliding frame 7 is about to move to the left to the larger through hole on the rightmost side of the sub-screen plate 4, the extrusion plate 1109 contacts the two first limit blocks 1106 on the rightmost side. As the extrusion plate 1109 continues to move to the right, the inclined surfaces of the two first limit blocks 1106 on the right squeeze and drive the extrusion plate 1109 to gradually move backward. The extrusion plate 1109 squeezes and drives the fixing rod 1108 and the piston plate 1104 to move backward, and the air in the air storage shell 1103 is squeezed and flows through the pipeline to the air on the first sliding frame 7. In the airbag, the airbag on the first sliding frame 7 gradually expands until the airbag on the first sliding frame 7 moves to the upper side of the through hole of the rightmost sub-screen plate 4. At this time, the lower side of the airbag expands to the rightmost through hole of the sub-screen plate 4. If there is codonopsis stuck in the rightmost through hole of the sub-screen plate 4, the airbag on the first sliding frame 7 is used to squeeze the codonopsis stuck in the through hole of the sub-screen plate 4, thereby solving the problem of codonopsis stuck in the through hole of the sub-screen plate 4 affecting screening, and improving the screening efficiency of codonopsis. In this process, since the airbag on the first sliding frame 7 is soft, the first sliding frame The airbag on 7 will not over-exert the Codonopsis pilosula, thereby preventing damage to the integrity of the Codonopsis pilosula. As the first sliding frame 7 continues to move to the left, the extrusion plate 1109 cooperates with the second limit block 1107 to squeeze the smaller through holes on the sub-screen plate 4. The extrusion plate 1109 cooperates with the first limit block 1106 to control the expansion of the airbag on the first sliding frame 7 in stages according to the position of the through holes on the sub-screen plate 4, thereby ensuring normal screening of the Codonopsis pilosula and preventing the Codonopsis pilosula from getting stuck due to its secondary roots, thereby improving the practicability of the device.

[0038] When the first sliding frame 7 moves to the left to the extreme position, taking the front extrusion plate 1109 as an example, the leftmost second limit block 1107 squeezes and drives the extrusion plate 1109 to move to the left rectangular frame of the first limit frame 1105, and the spring between the air storage shell 1103 and the piston plate 1104 drives the fixing rod 1108 and the extrusion plate 1109 to move forward through the left rectangular frame of the first limit frame 1105, and the gas in the airbag on the first sliding frame 7 is re-extracted into the air storage shell 1103. As the bidirectional screw 1101 continues to rotate, the bidirectional screw 1101 drives the fixing plate 1102 and the first sliding frame 7 Moving to the right, the extrusion plate 1109 contacts the left inclined surface of the first limiting frame 1105. As the extrusion plate 1109 continues to move to the right, the extrusion plate 1109 is squeezed and moves forward, and at the same time, the spring between the extrusion plate 1109 and the fixed rod 1108 is compressed. At this time, the extrusion plate 1109 moves to the front side of the first limiting frame 1105, and the first limiting frame 1105 limits the extrusion plate 1109. Then the first sliding frame 7 and the extrusion plate 1109 continue to move to the right until the extrusion plate 1109 is reset, and the spring between the extrusion plate 1109 and the fixed rod 1108 drives the extrusion plate 1109 to reset.

[0039] As the above-mentioned Codonopsis pilosula screening process proceeds, finer Codonopsis pilosula gradually accumulates in the temporary storage chamber on the left side of the dispersion rack 2, while coarser Codonopsis pilosula gradually accumulates in the temporary storage chamber on the right side of the dispersion rack 2. Taking the finer Codonopsis pilosula as an example, the user gradually arranges the Codonopsis pilosula with its head facing upward and places it in the equidistantly distributed through holes formed by the first fixed rack 1203 and the second sliding rack 1202. After the Codonopsis pilosula is placed in the through hole, the lower side of the Codonopsis pilosula first contacts the sliding plate 1206. After the Codonopsis pilosula of different lengths are placed, the heads of the Codonopsis pilosula will appear uneven. The user controls the electric slider in the electric slide rail in the fixed shell 1201 to drive the second sliding rack 1202 and the Codonopsis pilosula and parts thereon to move to the left. During this process, the second sliding rack 1202 drives the first fixed rack 1203 and its The two second limiting frames 1207, the two extrusion blocks 1208 and the two second fixed frames 1209 move to the left, and the two second fixed frames 1209 contact the first inclined surface on the right side of the third limiting frame 1210. Taking the front second fixed frame 1209 as an example, the second fixed frame 1209 is squeezed and moved forward by the first inclined surface on the right side of the third limiting frame 1210, and the second fixed frame 1209 drives the extrusion block 1208 to move forward. The front inclined surface of the extrusion block 1208 squeezes and drives the second limiting frame 1207 to move to the left, and the second limiting frame 1207 drives the extrusion frame 1204 and the fixed ropes 1205 evenly distributed thereon to move to the left relative to the first fixed frame 1203, and at the same time squeezes the spring between the second limiting frame 1207 and the first fixed frame 1203.

[0040] In the process that the above-mentioned extrusion frame 1204 and the equidistant fixed ropes 1205 thereon move to the left relative to the first fixed frame 1203, the equidistant fixed ropes 1205 gradually contact the Codonopsis pilosula carried on the sliding plate 1206, and the Codonopsis pilosula is squeezed to the left by the adjacent fixed ropes 1205 and contacts the right side of the second sliding frame 1202 for preliminary fixation. At this time, the second sliding frame 1202 and the Codonopsis pilosula on it move to the left to the lower side of the leveling plate 1306. As the second sliding frame 1202 and the Codonopsis pilosula on it continue to move to the left, the higher head of the Codonopsis pilosula contacts the lower inclined surface of the leveling plate 1306. As the Codonopsis pilosula on the second sliding frame 1202 gradually moves to the left, the lower inclined surface of the leveling plate 1306 contacts and squeezes the Codonopsis pilosula with the higher head downward, thereby leveling the Codonopsis heads of different lengths to ensure the height consistency of the Codonopsis heads when threading.

[0041] After the above-mentioned Codonopsis pilosula head is leveled, the second fixed frame 1209 squeezes and contacts the second inclined surface on the right side of the adjacent third limiting frame 1210. As the second sliding frame 1202 and the Codonopsis pilosula on it continue to move to the left, taking the front second fixed frame 1209 as an example, the second fixed frame 1209 is squeezed by the second inclined surface on the right side of the third limiting frame 1210 and continues to move forward, thereby driving the squeezing frame 1204 and the equidistantly distributed fixing ropes 1205 thereon to continue to move to the left to strengthen the fixation of the Codonopsis pilosula until the second sliding frame 1202 moves to the left and reaches the threading position. The user controls the electric slider in the electric slide rail on the fixed shell 1201 to drive the second sliding frame 1202 and the Codonopsis pilosula and parts thereon to stop moving to the left.

[0042] When the second sliding frame 1202 and the Codonopsis pilosula and parts on it move to the left to the threading position, the user drives the two power wheel groups 1302 to rotate together through external power, and the power wheel group 1302 drives the piercing iron rod to move backward. During this process, the piercing iron rod gradually passes through the Codonopsis pilosula until the piercing iron rod moves backward out of the rear power wheel group 1302. At this time, the threading of the Codonopsis pilosula is completed, and the upper piercing iron rod moves downward to the loading rack 1304. Then the user controls the threaded rod 1305 to rotate through external power, and the threaded rod 1305 drives the piercing iron rod inside it to continue to move backward through the thread until the piercing iron rod moves backward between the two power wheels. The user controls the threaded rod 1305 to reverse and drive the loading rack 1304 to reset. At this time, the loading is completed, and the extrusion rack 1204 cooperates with the leveling plate 1306 to initially fix the Codonopsis pilosula and then level it, and then the leveled Codonopsis pilosula is threaded through the power wheel group 1302, thereby ensuring the neatness of the Codonopsis pilosula after threading.

[0043] After the piercing of the codonopsis pilosula is completed, the user controls the electric slider in the electric slide rail on the fixed shell 1201 to drive the second sliding frame 1202 and the codonopsis pilosula and parts thereon to continue to move to the left, until the second sliding frame 1202 drives the threaded codonopsis pilosula to move to the left out of the lower side of the leveling plate 1306, at which time the second fixed frame 1209 contacts the leftmost inclined surface of the third limiting frame 1210. Taking the front second fixed frame 1209 as an example, the spring between the second limiting frame 1207 and the first fixed frame 1203 drives the second limiting frame 1207 to move to the right, and the second limiting frame 1 207 squeezes and drives the squeezing block 1208 and the second fixed frame 1209 to move backward, and the second limiting frame 1207 drives the squeezing frame 1204 and the fixing ropes 1205 evenly distributed thereon to move to the right, thereby losing the fixation of the Codonopsis pilosula. Then the user takes out the Codonopsis pilosula that has been threaded, and the electric slider in the electric slide rail on the user's fixed shell 1201 drives the second sliding frame 1202 and the parts thereon to move to the right and reset. The user repeats the above steps to continue screening and threading the Codonopsis pilosula until all the Codonopsis pilosula have been threaded, at which time the use of the device is completed.

[0044] Embodiment 2: Based on embodiment 1, Figure 1-Figure 3 and Fig.12 As shown, the conveyor belt of the conveying device 8 is provided with equally distributed through holes, and a dust collecting shell 14 is fixedly connected to the lower side of the dispersion frame 2. The side walls of the dust collecting shell 14 are all inclined surfaces for guiding the soil downward.

[0045] During the screening process of Codonopsis pilosula, the soil attached to the Codonopsis pilosula is gradually fallen off due to the influence of vibration and the like. In order to prevent a large amount of dust from occurring during the screening process, the following operations need to be performed: Before the screening begins, the user first connects a dust bag to the lower outlet of the dust collecting shell 14, and then performs screening. During the screening process, the soil attached to the Codonopsis pilosula moves downward into the dust collecting shell 14 through the through holes on the sieve plate 4 and the through holes on the conveyor belt on the conveying device 8. The soil continues to move downward under the guidance of the dust collecting shell 14 until the soil moves downward into the dust collecting bag. The soil that falls during the screening process is collected by the dust collecting shell 14 and the conveyor belt on the conveying device 8, thereby reducing the additional step of cleaning up the accumulated dust and improving the integrity of the working process of the device.

[0046] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
