Technical Field

[0001] The present invention relates to the technical field of fresh rhizome harvesting, and specifically to a fresh rehmannia rhizome harvesting device and method. Background Art

[0002] Fresh rehmannia is a herbaceous plant, and its fresh rhizome harvesting device is usually designed to collect and process the fresh stems and leaves of this plant. Large-scale production usually tends to use more advanced mechanical devices to improve efficiency and reduce labor costs, while maintaining product quality and hygiene standards.

[0003] The patent with the patent announcement number CN218649290U relates to a ginseng harvesting device convenient for harvesting, including a harvesting machine body. An installation frame is arranged on the harvesting machine body. A soil-shoveling tooth plate is arranged at the front end of the installation frame. A conveyor belt is arranged behind the soil-shoveling tooth plate. A sieve is arranged below the rear side of the conveyor belt. The sieve is inclined. A driving plate is arranged at the high end of the sieve. A collection box is arranged below the low end of the sieve. A driving box is arranged outside the driving plate. This patent uses a reciprocatingly rotatable sieve to quickly separate most of the soil from the ginseng plants lifted out of the soil, facilitating the collection of ginseng plants and improving the efficiency of ginseng collection.

[0004] In the above patent, it has the function of quickly separating most of the soil. By arranging a driving box outside the driving plate, the driving box drives the sieve to reciprocate and rotate, so that the ginseng plants lifted out of the soil by the sieve are quickly separated from most of the soil, which helps to reduce the workload of the staff and thus improve the efficiency of ginseng collection. However, when separating the soil, there is serious adhesion of the soil, resulting in the sieve being unable to effectively separate the soil. Summary of the Invention

[0014] A method for using a fresh rehmannia root harvesting device, comprising:

[0015] Step 1: The operator fixedly connects the mounting frame to the traction device. The movement of the traction device drives the movement of the mounting frame, the movement of the mounting frame drives the movement of the machine frame, and the movement of the machine frame drives the movement of the soil-shoveling tooth plate;

[0016] Step 2: The soil-shoveling tooth plate is inserted into the target soil during movement, so that the movement of the soil-shoveling tooth plate harvests the fresh rehmannia roots growing at the bottom of the soil, and the harvested fresh rehmannia roots fall onto the top of the conveyor belt under the guidance of the soil-shoveling tooth plate;

[0017] Step 3: Start the driving motor. The output end of the driving motor rotates to drive the roller to rotate, and the rotation of the roller drives the conveyor belt to move towards the collection box, and the movement of the conveyor belt drives the received fresh rehmannia roots to move towards the collection box;

[0018] Step 4: The fresh rehmannia roots fall into the interior of the collection box under the conveyance of the conveyor belt, so that the fresh rehmannia roots contact the top of the screening plate, and the screening plate discharges most of the soil adhering to the surface of the fresh rehmannia roots to the bottom of the collection box, thereby completing the separation work of most of the soil and the fresh rehmannia roots.

[0019] The present invention provides a fresh rehmannia root harvesting device, which has the following beneficial effects:

[0020] (1) In this fresh rehmannia root harvesting device, the rotating plate contacts and collides with the fresh rehmannia roots that are about to fall into the interior of the collection box during rotation. Through the intermittent contact between the first arc surface and the rotating plate, the rotating plate rotates reciprocally and collides with the soil on the surface of the fresh rehmannia roots, avoiding a high degree of soil adhesion and affecting the subsequent separation work. The rectangular block contacts the top of the limiting plate, so that the lifting rod is limited by the limiting plate applied by the limiting plate. By adjusting the position of the rotating plate, the staff can observe the soil adhesion degree and then select the pre-treatment, effectively improving the applicability of the rotating plate.

[0021] (2) For this fresh rehmannia root harvesting device, a downward pressure is applied to one side of the two pairs of arc-shaped screening plates. Affected by the pressure, the screening plates rotate. By intermittently applying a downward pressure to the screening plates through the L-shaped plates, the screening plates rotate back and forth in the collection box to improve the internal fluidity, prevent the top of the screening plates from being blocked, thereby enhancing the soil screening effect. When the rubber sheet contacts and collides with the blocking strip, vibrations are generated by the intermittent collision between the rubber sheet and the blocking strip, preventing the sliding plate from getting stuck. At the same time, when the rubber sheet resets, the collision is resolved through rotation to ensure that the sliding plate can smoothly reset, preparing for the subsequent screening.

[0022] (3) For this fresh rehmannia root harvesting device, the T-shaped plate drives the pushing plate to move. The movement of the pushing plate drives the fresh rehmannia roots to move away from the frame. By pushing the fresh rehmannia roots with the pushing plate, it is prevented that the fresh rehmannia roots accumulate and fall from the gaps between the frame and the collection box, causing the collection box to move and crush the fresh rehmannia roots. When the pushing plate moves and is affected by resistance, it stops moving. The T-shaped plate continues to move and squeezes the second elastic piece. When the resistance received by the pushing plate reaches the specified range, protection is carried out to prevent the pushing plate from forcibly moving and squeezing the collected fresh rehmannia roots, effectively improving the integrity of the fresh rehmannia root collection.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1-4 , an embodiment of the present invention is: A fresh rehmannia root harvesting device, including a frame 1, a soil-shoveling tooth plate 2 is fixedly installed on the surface of the frame 1, a mounting frame 3 is fixedly installed on the top of the frame 1, a roller 4 is rotatably installed on the inner wall of the frame 1, a driving motor 5 is fixedly penetrated through one side of the frame 1 close to the roller 4, a conveyor belt 6 is arranged on the circumferential surface of the roller 4, a collection box 7 is fixedly installed on the side of the frame 1 away from the soil-shoveling tooth plate 2, a screening plate 8 is rotatably installed on the inner wall of the collection box 7, the output end of the driving motor 5 is fixedly connected to the roller 4, a first scroll spring is arranged between the screening plate 8 and the collection box 7, and a processing device is further included; wherein, the processing device includes a loading plate 9, a lifting rod 10, a rotating plate 11, a holding rod 12, a first spring 13, a rectangular block 14, a plurality of limiting plates 15 and a contact plate 16. The loading plate 9 is fixedly penetrated through the inner and outer walls of the frame 1, the lifting rod 10 slides through the inner and outer walls of the loading plate 9, the rotating plate 11 rotates through one end of the lifting rod 10 close to the screening plate 8, the holding rod 12 slides through the other end of the lifting rod 10, the first spring 13 is arranged between the holding rod 12 and the lifting rod 10, the rectangular block 14 is fixedly installed on the circumferential surface of the holding rod 12, a plurality of limiting plates 15 are fixedly installed on the side of the loading plate 9 away from the screening plate 8, and the contact plate 16 is fixedly installed on the circumferential surface of the roller 4. By installing a rotatable screening plate 8 inside the collection box 7, the shaking generated when the collection box 7 moves drives the screening plate 8 to shake, thereby separating the soil.

[0034] One end of the contact plate 16 away from the roller 4 is provided with a first arc surface. A second volute spring is arranged between the rotating plate 11 and the lifting rod 10. Through the intermittent contact between the first arc surface and the rotating plate 11, the rotating plate 11 makes reciprocating rotations and collides with the soil on the surface of the fresh rehmannia root, so as to pre-treat the adhered soil and facilitate the subsequent soil separation.

[0035] The limiting plates 15 are symmetrically distributed with the center line of the loading plate 9 as the axis of symmetry. The bottom of the rectangular block 14 contacts the limiting plates 15. By standardizing the operation, the position of the rotating plate 11 can be quickly adjusted, so that the staff can observe the adhesion degree of the soil and then make a choice of pre-treatment, effectively improving the applicability of the rotating plate 11.

[0036] During the operation of this embodiment, the earth-removing tooth plate 2 is inserted into the target soil during movement, so that the movement of the earth-removing tooth plate 2 harvests the fresh rehmannia growing at the bottom of the soil. The harvested fresh rehmannia falls onto the top of the conveyor belt 6 under the guidance of the earth-removing tooth plate 2. The drive motor 5 is started, and the output end of the drive motor 5 rotates to drive the roller 4 to rotate. The rotation of the roller 4 drives the conveyor belt 6 to move towards the collection box 7. The movement of the conveyor belt 6 drives the received fresh rehmannia to move towards the collection box 7. At the same time, the rotation of the roller 4 drives the contact plate 16 to rotate towards the collection box 7. The first arc surface of the contact plate 16 contacts the rotating plate 11 near the top of the conveyor belt 6 during the rotation process. The rotation of the first arc surface exerts a downward thrust on the side of the rotating plate 11 close to the conveyor. The rotating plate 11 rotates away from the screening plate 8 under the action of the thrust. The rotating plate 11 stretches the second volute spring during the rotation process. The second volute spring deforms under the stretching force. At the same time, the rotating plate 11 contacts and collides with the fresh rehmannia that is about to fall into the collection box 7 during the rotation process. The first arc surface continues to rotate and separates from the surface of the rotating plate 11 that is in contact. The deformed second volute spring restores to drive the rotating plate 11 to reset. Through the intermittent contact between the first arc surface and the rotating plate 11, the rotating plate 11 makes a reciprocating rotation and collides with the soil on the surface of the fresh rehmannia. When the rotating plate 11 is not needed, the drive motor 5 is turned off, and the grip 12 is pulled to move away from the lifting rod 10. The grip 12 stretches the first spring 13 during the movement process. The first spring 13 deforms during the stretching process. At the same time, the movement of the grip 12 drives the rectangular block 14 to move away from the lifting rod 10. The rectangular block 14 separates from the bottom of the limiting plate 15 during the movement process, so that the limit applied by the limiting plate 15 to the lifting rod 10 is released. The grip 12 is pushed upward. The movement of the grip 12 drives the lifting rod 10 to move upward. The movement of the lifting rod 10 drives the rotating plate 11 to move upward. After the lifting rod 10 moves to a predetermined position, the pulling force applied to the grip 12 is reduced, so that the deformed first spring 13 restores under its own elasticity. The restoration of the first spring 13 drives the grip 12 to move towards the lifting rod 10. The movement of the grip 12 drives the rectangular block 14 to move towards the lifting rod 10. The rectangular block 14 contacts the top of the limiting plate 15 during the movement process, so that the movement of the lifting rod 10 is limited by the limiting plate 15. At the same time, the first arc surface does not contact the rotating plate 11 during the rotation process. By adjusting the position of the rotating plate 11, the staff can observe the adhesion of the soil and then select the pre-treatment method, effectively improving the applicability of the rotating plate 11.

[0037] Please refer to Figures 1-8, on the basis of the above embodiments, in another embodiment of the present invention, a separation device and a protection device are further included; the separation device includes a carrying frame 171, a sliding plate 172, a second spring 173, an L-shaped plate 174, a rubber sheet 175, a baffle 176 and a blocking strip 177. The carrying frame 171 is fixedly installed on the inner wall of the collection box 7 close to the conveyor belt 6. The sliding plate 172 is slidably installed on the top of the carrying frame 171. The second spring 173 is arranged between the sliding plate 172 and the carrying frame 171. The L-shaped plate 174 is fixedly installed on the side of the sliding plate 172 away from the carrying frame 171. The rubber sheet 175 is rotatably installed on the inner wall of the sliding plate 172. The baffle 176 is fixedly installed on the inner wall of the sliding plate 172. The blocking strip 177 is fixedly installed on the inner wall of the carrying frame 171. An inclined surface one is opened on the top of the sliding plate 172. By intermittently applying a downward pressure to the screening plate 8 through the L-shaped plate 174, the screening plate 8 is made to rotate reciprocally, thereby improving the effect of screening soil.

[0038] An arc surface two is opened at the bottom of the L-shaped plate 174. The top of the baffle 176 contacts the rubber sheet 175. By applying a pressure to one side of the screening plate 8 through the L-shaped plate 174, it is ensured that the screening plate 8 can rotate stably, thereby improving the stability of use.

[0039] An arc surface three is opened on the side of the rubber sheet 175 close to the blocking strip 177. A third scroll spring is arranged between the rubber sheet 175 and the sliding plate 172. An arc surface four is opened at the top of the blocking strip 177. By intermittently colliding between the rubber sheet 175 and the blocking strip 177 to generate vibration, the situation that the sliding plate 172 is stuck is avoided. At the same time, when the rubber sheet 175 resets, the resistance is resolved by rotation to ensure that the reset of the sliding plate 172 is not affected.

[0040] The protection device includes a placement box 181, a round rod 182, a moving plate 183, a third spring 184, a T-shaped plate 185, a first elastic sheet 186, a pushing plate 187 and a second elastic sheet 188. The placement box 181 is fixedly installed on the inner wall of the collection box 7 close to the carrying frame 171. The round rod 182 slidably penetrates through the inner and outer walls of the placement box 181. The moving plate 183 is fixedly installed at one end of the round rod 182 close to the placement box 181. The third spring 184 is arranged between the placement box 181 and the moving plate 183. The T-shaped plate 185 slidably penetrates through the side of the placement box 181 away from the collection box 7. The first elastic sheet 186 is arranged between the T-shaped plate 185 and the placement box 181. The pushing plate 187 slidably penetrates through the side of the T-shaped plate 185 away from the placement box 181. The second elastic sheet 188 is arranged between the pushing plate 187 and the T-shaped plate 185. The round rod 182 contacts the bottom of the L-shaped plate 174. By pushing the fresh rehmannia glutinosa through the pushing plate 187, it is avoided that the fresh rehmannia glutinosa accumulates and falls from the gap to between the frame 1 and the collection box 7, resulting in the collection box 7 moving and rolling over the fresh rehmannia glutinosa.

[0041] The bottom of the moving plate 183 is provided with a second inclined surface, and the surface close to the moving plate 183 of the T-shaped plate 185 is provided with a fifth arc surface. When the resistance received by the pushing plate 187 reaches a specified range, protection is carried out to prevent the pushing plate 187 from being forced to move and squeezing the collected fresh rehmannia roots, thus ensuring the integrity of the collection of the packaged fresh rehmannia roots.

[0042] During the operation of this embodiment, the first arc surface contacts the first inclined surface during rotation, and the movement of the first arc surface applies a downward pressure to the first inclined surface. The sliding plate 172 moves downward under the action of the pressure. During the movement of the sliding plate 172, the second spring 173 is squeezed, and the second spring 173 deforms under the squeeze. At the same time, the movement of the sliding plate 172 drives the L-shaped plate 174 to move downward. The second arc surface of the L-shaped plate 174 contacts the top of the screening plate 8 during the movement. The movement of the second arc surface applies a downward pressure to the side of the screening plate 8 close to the carrying frame 171. One side of the screening plate 8 rotates under the influence of the pressure. The screening plate 8 stretches the first volute spring during rotation, and the first volute spring deforms under the stretch. When the surface of the first arc surface in contact with the first inclined surface separates, the deformed second spring 173 restores and drives the sliding plate 172 to move upward. The movement of the sliding plate 172 drives the L-shaped plate 174 to move upward. The surface of the second arc surface in contact with the screening plate 8 separates, so that the pressure applied by the L-shaped plate 174 to the screening plate 8 gradually decreases. The deformed first volute spring restores and drives the screening plate 8 to reset. By intermittently applying a downward pressure to the screening plate 8 through the L-shaped plate 174, the screening plate 8 reciprocally rotates to improve the effect of screening soil. When the sliding plate 172 moves downward, it drives the rubber sheet 175 to move downward. The third arc surface of the rubber sheet 175 contacts and collides with the fourth arc surface of the blocking bar 177 during the movement. Since the baffle 176 contacts the top of the rubber sheet 175, the upward rotation of the rubber sheet 175 is blocked by the baffle 176, resulting in the resistance applied by the fourth arc surface to the movement of the third arc surface, so that the rubber sheet 175 deforms under the influence of the resistance during movement. When the third arc surface continues to move and separates from the fourth arc surface, the deformed rubber sheet 175 restores under the action of its own elasticity. When the sliding plate 172 resets, it drives the rubber sheet 175 to move upward. The rubber sheet 175 contacts the bottom of the blocking bar 177 during the movement, so that the movement of the rubber sheet 175 is blocked by the blocking bar 177 and rotates away from the baffle 176. The rubber sheet 175 stretches the third volute spring during rotation, and the third volute spring deforms under the stretch. The deformed rubber sheet 175 continues to move and separates from the blocking bar 177, so that the deformed rubber sheet 175 automatically restores. By intermittently colliding the rubber sheet 175 with the blocking bar 177 to generate vibration, the situation of the sliding plate 172 being stuck is avoided, and at the same time, when the rubber sheet 175 resets, the resistance is resolved through rotation;

[0043] The L-shaped plate 174 moves downward to exert a downward thrust on the round rod 182. Under the action of the thrust, the round rod 182 moves downward. The movement of the round rod 182 drives the moving plate 183 to move downward. When the moving plate 183 moves, it stretches the third spring 184. At the same time, the second inclined surface of the moving plate 183 contacts the fifth arc surface during the movement. The movement of the second inclined surface exerts a thrust on the fifth arc surface. Affected by the thrust, the T-shaped plate 185 moves away from the moving plate 183. During the movement, the T-shaped plate 185 stretches the first elastic piece 186, and the first elastic piece 186 deforms under the stretching. At the same time, the movement of the T-shaped plate 185 drives the push plate 187 to move away from the placement box 181. The movement of the push plate 187 drives the fresh rehmannia in the collection box 7 to move away from the frame 1. By pushing the fresh rehmannia with the push plate 187, it is avoided that the fresh rehmannia accumulates and falls from the gap between the frame 1 and the collection box 7, resulting in the collection box 7 moving and crushing the fresh rehmannia. When the push plate 187 pushes the fresh rehmannia to move, the resistance it receives gradually increases. When the resistance reaches the specified range, the push plate 187 stops moving under the influence of the resistance. The T-shaped plate 185 continues to move and squeezes the second elastic piece 188, and the second elastic piece 188 deforms under the squeeze. When the T-shaped plate 185 resets, the thrust applied to the second elastic piece 188 is reduced, so that the second elastic piece 188 is restored under the action of its own elasticity. At the same time, the movement of the T-shaped plate 185 drives the push plate 187 to move towards the placement box 181. When the resistance received by the push plate 187 reaches the specified range, protection is carried out to avoid the push plate 187 moving forcibly and squeezing the collected fresh rehmannia.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
