Description

Technical Field

[0001] The invention relates to the technical field of traditional Chinese medicine harvesting equipment, in particular to a codonopsis pilosula harvester. Background Art

[0002] Codonopsis pilosula is a traditional Chinese medicinal material unique to my country. As a commonly used Chinese medicine, it comes from the dried roots of Codonopsis pilosula, Codonopsis pilosula, or Codonopsis pilosula of the Campanulaceae family. Codonopsis pilosula is sweet in taste and neutral in nature. It has the effects of tonifying the middle and replenishing qi, quenching thirst, strengthening the spleen and lungs, nourishing blood and producing body fluid. It is used for spleen and lung qi deficiency, poor appetite and fatigue, cough and weak asthma, insufficient qi and blood, sallow complexion, palpitations and shortness of breath, thirst due to loss of body fluid, internal heat and thirst, laziness and shortness of breath, weakness in the limbs, poor appetite, qi deficiency, deficiency of both qi and body fluid, deficiency of both qi and blood, and blood deficiency and sallow complexion. The efficacy of this product is similar to that of ginseng, but its medicinal power is weak.

[0003] Publication (announcement) number: CN117480930A, discloses a deep-rooted and stemmed Chinese medicinal material harvester, the device includes: a frame, an excavating device, which is arranged at the bottom of the front end of the frame, a feeding device, which is arranged in the frame, and the feeding end corresponds to the excavating device, a screening device, which is arranged in the frame and located at the rear end of the feeding device, a power transmission system, which is arranged on the frame and transmits power to the feeding device and the screening device in turn, and two ground wheels, which are respectively arranged on both sides of the tail of the frame, wherein the feeding device includes: a first-level feeding roller, which is horizontally arranged in the frame and located at the rear end of the excavating device, a second-level feeding roller, which is horizontally arranged in the frame and located at the rear end of the first-level feeding roller, and the second-level feeding roller is connected to the first-level feeding roller through a transmission assembly.

[0004] In order to improve work efficiency, the existing market uses automated machinery to harvest mature Codonopsis pilosula. However, during actual operation, traditional Codonopsis pilosula harvesters only have a preliminary soil crushing function for Codonopsis pilosula, and are unable to further separate the soil adhering to the surface of Codonopsis pilosula, resulting in the need for further surface fine cleaning of Codonopsis pilosula after harvesting, increasing the cost of Codonopsis pilosula harvesting. At the same time, traditional Codonopsis pilosula harvesters are unable to control the storage location of the harvested Codonopsis pilosula in the first place according to the needs of the operator (either stacking them in a collection box or directly laying them on the ground), thus having limitations in use. Summary of the invention

[0005] The invention discloses a codonopsis pilosula harvester, aiming to solve the problem that traditional codonopsis pilosula harvesters on the existing market only have the function of roughly crushing the codonopsis pilosula during actual operation, which results in the need for further surface fine cleaning of the codonopsis pilosula after harvesting, increasing the cost of harvesting the codonopsis pilosula; at the same time, traditional codonopsis pilosula harvesters cannot control the storage points of the harvested codonopsis pilosula in the first time according to the needs of operators, and also have technical problems with limitations when in use.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A codonopsis pilosula harvester comprises a frame, wherein a harvesting mechanism for removing soil from the codonopsis pilosula is arranged at one end of the frame;

[0008] The other end of the frame is provided with a reprocessing mechanism for re-soil removal of the surface of the Codonopsis pilosula, the reprocessing mechanism comprises a rotating disk rotatably mounted on one side of the frame, the rotating disk is provided with a first annular groove, a plurality of evenly arranged brush steel rollers are distributed inside the first annular groove, and the end of the brush steel roller is slidably mounted inside the first annular groove;

[0009] A switching mechanism for changing the operating mode of the frame is disposed on the side of the reprocessing mechanism, and the switching mechanism includes an extrusion member, and the extrusion member penetrates through the middle of the rotating disk;

[0010] A collecting mechanism for centrally stacking codonopsis pilosula is provided on the side of the vehicle frame;

[0011] The harvesting mechanism cooperates with the movement of the frame to lift the Codonopsis pilosula off the ground and remove the soil. At the same time, the Codonopsis pilosula after lifting off the ground will enter the reprocessing mechanism for surface soil removal. By disassembling and assembling the switching mechanism and coordinating with the operation of the collecting mechanism, two operating modes can be realized: centralized stacking of the Codonopsis pilosula after soil removal and direct laying of the Codonopsis pilosula in the field.

[0012] A harvesting mechanism is provided inside the frame, and the harvesting mechanism cooperates with the movement of the frame to lift the Codonopsis pilosula buried in the soil off the ground. At the same time, the Codonopsis pilosula after lifting off the ground will enter the reprocessing mechanism for surface soil removal, so that the soil adhering to the surface of the Codonopsis pilosula can be directly removed when the Codonopsis pilosula is harvested, thereby improving the quality of the Codonopsis pilosula when harvested. By disassembling and assembling the additional switching mechanism, it can cooperate with the operation of the collecting mechanism to realize two operating modes: centralized stacking of the Codonopsis pilosula after soil removal and direct laying of the Codonopsis pilosula in the field, thereby improving the functionality and work efficiency of traditional Codonopsis pilosula harvesters.

[0013] In a preferred embodiment, the harvesting mechanism includes a transmission installed inside the frame, the output end of the transmission passes through the side of the frame, and the first steel roller conveyor belt group and the second steel roller conveyor belt group are rotatably installed inside the frame. The first steel roller conveyor belt group and the second steel roller conveyor belt group are staggered in the horizontal direction. At the same time, a first transmission belt is connected between the output end of the transmission and the second steel roller conveyor belt group, and a second transmission belt is connected between the first steel roller conveyor belt group and the second steel roller conveyor belt group. A shovel plate is fixedly installed below the end of the frame, and the shovel plate is distributed at one end of the first steel roller conveyor belt group.

[0014] A first steel roller conveyor belt group and a second steel roller conveyor belt group driven by a transmission are arranged inside the frame, and the frame is moved along the field. The shovel plate is inserted into the soil, and the codonopsis mixed with soil is carried to the top of the first steel roller conveyor belt group and the second steel roller conveyor belt group. The codonopsis is screened by the rotating first steel roller conveyor belt group and the second steel roller conveyor belt group, so that the codonopsis is screened out from the soil, the harvesting of the codonopsis is completed, and the rationality of the equipment function is guaranteed.

[0015] In a preferred embodiment, the reprocessing mechanism also includes a plurality of evenly distributed telescopic rods installed on the inner side of the rotating disk, the ends of the plurality of telescopic rods are commonly connected to an elastic member, the elastic member is sleeved on the outer sides of the ends of the plurality of brush steel rollers, an annular disk is installed on the other side of the interior of the frame, and the other ends of the plurality of brush steel rollers are slidably installed inside the annular disk.

[0016] By providing a plurality of brush steel roller structures slidably installed on the inner side of a rotating disk, the rotating disk is used to drive the brush steel rollers to revolve synchronously. At the same time, the brush steel rollers are connected by elastic parts. The elastic parts between the two upper groups of brush steel rollers are squeezed by the switching mechanism to deform and push the corresponding brush steel rollers to move, so that the codonopsis pilosula falling from the second steel roller conveyor belt group can enter the interior of the plurality of brush steel rollers through the gaps between the brush steel rollers, thereby completing the secondary soil removal treatment of the codonopsis pilosula surface along with the revolution of the brush steel rollers, thereby greatly improving the harvesting quality of the equipment.

[0017] In a preferred solution, the switching mechanism also includes a base fixedly mounted on the outer side of the frame, a threaded rod is fixed on the side of the extrusion member away from the brush steel roller, the threaded rod passes through the base and is connected by a nut, the top of the extrusion member is in extrusion contact with the elastic member, a back plate is installed at the end of the frame and close to the reprocessing mechanism, and an inclined plate is fixed on the side of the back plate.

[0018] By providing an extrusion piece structure threadedly mounted on the base and cooperating with the rotation of the rotating disk, the top of the elastic piece is squeezed, thereby completing the adjustment of the gap between the two groups of brush steel rollers on the top, and cooperating with the operation of the collecting mechanism, the processed Codonopsis pilosula can be collected; at the same time, when the operator disassembles the extrusion piece and the back plate together as needed, the several brush steel rollers rotating with the rotating disk at this time only have the function of crushing the Codonopsis pilosula, and the crushed Codonopsis pilosula is thrown into the field through the end of the frame and the original position of the back plate, so that the drop point of the harvested Codonopsis pilosula can be controlled according to needs, thereby improving the functionality of traditional Codonopsis pilosula harvesters.

[0019] In a preferred solution, the collecting mechanism comprises a collecting bin mounted on the side of the frame, a push plate conveyor belt group is rotatably mounted inside the collecting bin, a collecting box is mounted on the top of the frame, and the collecting bin and the collecting box are docked.

[0020] A push plate conveyor belt group driven by a transmission is provided to transport the codonopsis pilosula that falls out of the annular disk and transport the codonopsis pilosula to the inside of a collecting box, thereby realizing centralized stacking of the codonopsis pilosula and improving the completeness of the operation of the equipment.

[0021] In a preferred solution, the elastic member includes a plurality of connecting sleeves sleeved on the ends of the brush steel rollers, the connecting sleeves are connected to each other via first elastic sheets, and the extrusion member is in extrusion contact with the first elastic sheets.

[0022] A plurality of connecting sleeve structures are provided which are sleeved on the outside of the brush steel roller. The connecting sleeves are connected to each other by a first spring sheet. The first spring sheet is squeezed and pushed by the extrusion piece to cause the first spring sheet to deform, thereby pushing the connecting sleeve and the brush steel roller to move along the inside of the first annular groove, thereby adjusting the distance between the two brush steel rollers at the top, allowing the codonopsis to fall into the cylindrical structure composed of the plurality of brush steel rollers, thereby ensuring the integrity of the operation of the equipment.

[0023] As can be seen from the above, the Codonopsis pilosula harvester provided by the present invention has the following improvements and advantages compared with the prior art:

[0024] First, a first steel roller conveyor belt group and a second steel roller conveyor belt group driven by a transmission are arranged inside the frame, and the frame is moved along the field. The shovel is inserted into the soil to carry the codonopsis mixed with soil to the top of the first steel roller conveyor belt group and the second steel roller conveyor belt group, and the codonopsis pilosula is initially screened by the rotating first steel roller conveyor belt group and the second steel roller conveyor belt group, so that the codonopsis pilosula is screened out from the soil. At the same time, a plurality of brush steel roller structures are additionally arranged that are slidably installed on the inner side of the rotating disk, and the codonopsis pilosula is screened out from the soil by the rotating disk belt. The dynamic elastic part revolves, and the brush steel roller rotates synchronously due to the connection of the elastic part. At this time, the elastic part between the two brush steel rollers directly above will be squeezed by the switching mechanism, thereby deforming and pushing the corresponding two brush steel rollers to move, so that the Codonopsis pilosula falling from the second steel roller conveyor belt group can pass through the gap between the brush steel rollers and enter the interior of the cylindrical structure composed of several brush steel rollers. Accompanied by the revolution of the brush steel rollers, the secondary soil removal treatment of the Codonopsis pilosula surface is completed, thereby greatly improving the harvesting quality and efficiency of this equipment.

[0025] Secondly, an extrusion piece structure threadedly mounted on the base cooperates with the rotation of the rotating disk to squeeze the top of the elastic piece, thereby completing the adjustment of the gap between the two groups of brush steel rollers on the top, and cooperating with the operation of the push plate conveyor belt group, the processed Codonopsis pilosula can be concentratedly stacked inside the collection box; at the same time, when the operator disassembles the extrusion piece and the back plate together as needed, the several brush steel rollers rotating with the rotating disk form a stable cylindrical structure, which makes it impossible for the Codonopsis pilosula to enter between the several brush steel rollers, so that the Codonopsis pilosula only has the function of crushing the soil, and the crushed Codonopsis pilosula is thrown into the field through the end of the frame and the original position of the back plate, so that the Codonopsis pilosula harvester can control the drop point of the harvested Codonopsis pilosula according to needs (stored in the collection box or directly thrown into the field), thereby improving the functionality of traditional Codonopsis pilosula harvesters.

[0040] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0041] The codonopsis pilosula harvester disclosed in the present invention is mainly used in the scene of codonopsis pilosula harvesting.

[0042] Reference Figures 1 to 13 A codonopsis pilosula harvester comprises a frame 1, wherein a harvesting mechanism 2 for removing soil from codonopsis pilosula is arranged at one end of the frame 1;

[0043] The other end of the frame 1 is provided with a reprocessing mechanism 3 for re-soil removal of the surface of the Codonopsis pilosula. The reprocessing mechanism 3 includes a rotating disk 301 rotatably mounted on one side of the frame 1. The rotating disk 301 is provided with a first annular groove 302. A plurality of uniformly arranged brush steel rollers 303 are distributed inside the first annular groove 302. The end of the brush steel roller 303 is slidably mounted inside the first annular groove 302.

[0044] A switching mechanism 4 for changing the operating mode of the frame 1 is disposed on the side of the reprocessing mechanism 3. The switching mechanism 4 includes an extrusion member 401, and the extrusion member 401 penetrates through the middle of the rotating disk 301.

[0045] A collecting mechanism 5 for centrally stacking Codonopsis pilosula is provided on the side of the vehicle frame 1;

[0046] The harvesting mechanism 2 cooperates with the movement of the frame 1 to remove the soil from the Codonopsis pilosula. After leaving the ground, the Codonopsis pilosula will enter the reprocessing mechanism 3 for surface desoiling. Through the operation of the disassembly and assembly switching mechanism 4 and the collection mechanism 5, two operating modes can be realized, namely, centralized stacking and direct laying in the field of the Codonopsis pilosula after desoiling.

[0047] In this embodiment: before use, the operator docks the frame 1 with the agricultural tractor, starts the tractor and moves the frame 1 to the Codonopsis field, and at the same time pushes the frame 1 to tilt through an external hydraulic device, inserts the harvesting mechanism 2 into the soil, and then the operator controls the tractor to move along the field. While moving, the harvesting mechanism 2 will shovel out the Codonopsis buried in the soil and transport it along the inside of the frame 1, and separate the Codonopsis from large pieces of soil and gravel while transporting. When the frame 1 is equipped with a switching mechanism 4, the Codonopsis moving along the inside of the frame 1 will fall into the inside of the reprocessing mechanism 3, and the reprocessing mechanism 3 will continue to roll with the Codonopsis and scrape off the soil adhering to the outer surface of the Codonopsis, and at the same time transport the Codonopsis to the inside of the collecting mechanism 5 for centralized stacking; when the switching mechanism 4 inside the frame 1 is disassembled, the Codonopsis transported along the inside of the frame 1 will pass over the outside of the reprocessing mechanism 3 and fall into the field, and the rotating reprocessing mechanism 3 collides with the Codonopsis and only serves to break the soil on the surface of the Codonopsis.

[0048] It should be additionally explained that: a plurality of uniformly distributed reinforcing rods 207 are fixedly mounted on the bottom of the frame 1 , and the structural strength of the frame 1 is improved by the reinforcing rods 207 .

[0049] In the above scheme, considering that in order to peel Codonopsis pilosula from the mud, the specific operations are as follows.

[0050] Reference Figures 1 to 5 In a preferred embodiment, the harvesting mechanism 2 includes a transmission 201 installed inside the frame 1, the output end of the transmission 201 passes through the side of the frame 1, and the first steel roller conveyor belt group 202 and the second steel roller conveyor belt group 203 are rotatably installed inside the frame 1. The first steel roller conveyor belt group 202 and the second steel roller conveyor belt group 203 are staggered in the horizontal direction. At the same time, a first transmission belt 204 is connected to the transmission sleeve between the output end of the transmission 201 and the second steel roller conveyor belt group 203, and a second transmission belt 205 is connected to the transmission sleeve between the first steel roller conveyor belt group 202 and the second steel roller conveyor belt group 203. A shovel plate 206 is fixedly installed below the end of the frame 1, and the shovel plate 206 is distributed at one end of the first steel roller conveyor belt group 202.

[0051] In this embodiment: the operator docks the frame 1 with the agricultural tractor, starts the tractor and moves the frame 1 to the Codonopsis field, and at the same time pushes the frame 1 to tilt through an external hydraulic device, inserts the shovel 206 into the soil, and then the operator controls the tractor to move along the field. While moving, the transmission 201 is started, and the first steel roller conveyor belt group 202 and the second steel roller conveyor belt group 203 are driven to rotate through the first transmission belt 204 and the second transmission belt 205. The shovel 206 will shovel out the Codonopsis buried in the soil and use the first steel roller conveyor belt group 202 and the second steel roller conveyor belt group 203 to transport it along the inside of the frame 1, and separate the Codonopsis from large pieces of soil and gravel during transportation.

[0052] The transmission 201 is connected to the rear output shaft of the tractor for transmitting rotation.

[0053] In the above scheme, in order to further peel off the dirt adhering to the surface of Codonopsis pilosula, the specific operation is as follows.

[0054] Reference Figures 3 to 5 , Figures 7 to 11 In a preferred embodiment, the complex processing mechanism 3 also includes a plurality of evenly distributed telescopic rods 304 installed on the inner side of the rotating disk 301, and the ends of the plurality of telescopic rods 304 are commonly connected to an elastic member 305, and the elastic member 305 is sleeved on the outer side of the ends of the plurality of brush steel rollers 303. An annular disk 306 is installed on the other side of the inside of the frame 1, and the other ends of the plurality of brush steel rollers 303 are slidably installed inside the annular disk 306.

[0055] In this embodiment, when the switching mechanism 4 is installed inside the frame 1, along with the operation of the transmission 201, the rotating disk 301 will rotate synchronously, and at the same time, the elastic member 305 will be driven to rotate synchronously through the telescopic rod 304, and the synchronously rotating elastic member 305 will drive a plurality of brush steel rollers 303 to rotate. Along with the rotation of the plurality of brush steel rollers 303, when the elastic member 305 between the two upper brush steel rollers 303 is squeezed, deformation will occur (such as Fig. 9As shown in the figure, the two brush steel rollers 303 are pushed to move in the opposite direction along the inside of the first annular groove 302, causing the gap between the two brush steel rollers 303 located above to increase. As the rotating disk 301 continues to rotate, the two brush steel rollers 303 that have lost the squeezing of the switching mechanism 4 will be pulled by the elastic member 305 to reset and move. In this way, in the cylindrical structure composed of a plurality of brush steel rollers 303, the distance between the two brush steel rollers 303 located above is always in an expanded state. At this time, the Codonopsis pilosula moving along the inside of the vehicle frame 1 will fall into the cylindrical structure composed of a plurality of brush steel rollers 303. The brush steel rollers 303 continue to roll with the Codonopsis pilosula and scrape off the dirt adhering to the outer surface of the Codonopsis pilosula, while pushing the Codonopsis pilosula toward the annular disk 306. The dang pilosula is transported in the direction until it is transported to the inside of the collecting mechanism 5 for centralized stacking; wherein, a third transmission belt 308 is connected with a transmission sleeve between the second steel roller conveyor belt group 203 and the rotating disk 301, and the ends of several brush steel rollers 303 are located in the second annular groove on one side of the annular disk 306, and the ends of two adjacent brush steel rollers 303 are connected with second elastic pieces 307, and the second elastic pieces 307 are located in the second annular groove on one side of the annular disk 306, and the ends of each brush steel roller 303 are elastically connected by the second elastic pieces 307, so as to ensure the structural stability and avoid the shaking of a single brush steel roller 303 during the rotation of the cylindrical structure composed of the brush steel rollers 303; and the entire complex processing mechanism 3 is tilted and distributed toward the direction of the collecting mechanism 5.

[0056] Furthermore, the elastic member 305 includes a plurality of connecting sleeves 3051 sleeved on the ends of the brush steel rollers 303, and the connecting sleeves 3051 are connected to each other through the first spring sheet 3052, and the extrusion member 401 is in extrusion contact with the first spring sheet 3052; when the rotating disk 301 rotates, the elastic member 305 is driven to rotate synchronously through the telescopic rod 304, and the synchronously rotating elastic member 305 drives the cylindrical structure composed of the plurality of brush steel rollers 303 to rotate, and the brush steel rollers 303 are connected to each other through the first spring sheet 3052; The cylindrical structure rotates, and when the first spring piece 3052 between the two upper brush steel rollers 303 is squeezed, it will deform outward, so that the connecting sleeve 3051 pushes the two brush steel rollers 303 to move in the opposite direction along the inside of the first annular groove 302, causing the gap between the two upper brush steel rollers 303 to increase. As the rotating disk 301 continues to rotate, the two brush steel rollers 303 that have lost the squeezing of the switching mechanism 4 will be pulled by the first spring piece 3052 and reset.

[0057] In the above scheme, considering that it is convenient for users to change the stacking location of the harvested Codonopsis pilosula according to their needs, the specific operations are as follows.

[0058] Reference Figure 2 , Figures 7 to 9In a preferred embodiment, the switching mechanism 4 also includes a base 402 fixedly installed on the outer side of the frame 1, a threaded rod 4011 is fixed on the side of the extrusion member 401 away from the brush steel roller 303, the threaded rod 4011 passes through the base 402 and is connected by a nut 4012, the top of the extrusion member 401 is in extrusion contact with the elastic member 305, a back plate 403 is installed at the end of the frame 1 and close to the reprocessing mechanism 3, and an inclined plate 4031 is fixed on the side of the back plate 403.

[0059] In this embodiment, when the extrusion member 401 is installed inside the frame 1, the rotating disk 301 will rotate synchronously with the operation of the transmission 201, and the elastic member 305 will be driven to rotate synchronously through the telescopic rod 304, and the synchronously rotating elastic member 305 will drive the cylindrical structure composed of the brush steel rollers 303 to rotate. As the cylindrical structure composed of the brush steel rollers 303 rotates, the elastic member 305 between the two upper brush steel rollers 303 will be squeezed by the extrusion member 401, thereby deforming outwards, pushing the two brush steel rollers 303 to rotate. The brush steel rollers 303 move in the opposite direction along the inside of the first annular groove 302, causing the gap between the two brush steel rollers 303 located above to increase; when the user turns the nut 4012 and the threaded rod 4011, and removes the extrusion piece 401 from the base 402, the operator needs to remove the back plate 403 at the same time. At this time, when it falls to the top of the cylindrical structure composed of several brush steel rollers 303, the codonopsis pilosula cannot enter the inside of the cylindrical structure, and will be rolled by the brush steel rollers 303 and fall from the end of the frame 1 into the field. The specific running trajectory is as follows Figure 3 shown.

[0060] Among them, it should be supplemented that: after the extrusion piece 401 is separated from the top telescopic rod 304 and before it contacts the next telescopic rod 304, there is a probability that the Codonopsis pilosula that falls during this period cannot enter the cylindrical structure composed of the brush steel roller 303. At this time, the inclined plate 4031 blocks and restricts the Codonopsis pilosula that has not entered the cylindrical structure composed of the brush steel roller 303 until the Codonopsis pilosula enters the cylindrical structure composed of the brush steel roller 303. Since the lower end of the inclined plate 4031 and the brush steel roller 303 are in a non-contact state, there is a gap between the lower end of the inclined plate 4031 and the cylindrical structure composed of the brush steel roller 303. In order to prevent Codonopsis pilosula or impurities from falling between the back plate 403 and the brush steel roller 303 through the gap, a brush structure is provided at the end of the inclined plate 4031. The brush structure is used to flexibly block the gap to ensure that the Codonopsis pilosula fully falls into the cylindrical structure composed of the brush steel roller 303 and prevent jamming.

[0061] Further, if Figure 6As shown, the supplementary explanation is as follows: a guide plate 6 is installed on the inner wall of the frame 1 and above the second steel roller conveyor belt group 203. The guide plate 6 guides the Codonopsis pilosula transported on the top of the second steel roller conveyor belt group 203, and transports the Codonopsis pilosula into the reprocessing mechanism 3 in a direction away from the annular disk 306, thereby improving the soil removal process of the Codonopsis pilosula in the reprocessing mechanism 3. The guide plate 6 can be disassembled and assembled later as needed.

[0062] In the above plan, considering the centralized storage of the harvested Codonopsis pilosula, the specific operations are as follows.

[0063] Reference Figures 1 to 3 , Figures 5 and 6 In a preferred embodiment, the collecting mechanism 5 includes a collecting bin 501 installed on the side of the frame 1, a push plate conveyor belt group 502 is rotatably installed inside the collecting bin 501, a collecting box 503 is installed on the top of the frame 1, and the collecting bin 501 and the collecting box 503 are connected.

[0064] In this embodiment: while the transmission 201 is running, the push plate conveyor belt set 502 is started synchronously, at which time the codonopsis pilosula transported from the direction of the annular disk 306 will fall onto the push plate conveyor belt set 502, and will be centrally transported to the inside of the collection box 503 as the push plate conveyor belt set 502 rotates; wherein, the second steel roller conveyor belt set 203 and the push plate conveyor belt set 502 are connected by a fourth transmission belt 504 and a transmission gear set 505, and the transmission gear set 505 is composed of two gears meshing with each other (the transmission gear set 505 is hidden in the collection bin 501, Figure 6 ), specifically, Fig.13 As shown, the fourth transmission belt 504 rotates clockwise, and after the transmission gear set 505 changes direction, the push plate conveyor belt set 502 rotates counterclockwise, which can lift the materials in the collection bin 501 upward.

[0065] Working principle: When in use, the operator docks the frame 1 with the agricultural tractor, starts the tractor and moves the frame 1 to the Codonopsis field, and at the same time pushes the frame 1 to tilt through the external hydraulic device, inserts the shovel 206 into the soil, and then the operator controls the tractor to move along the field. While moving, the transmission 201 is started, and the first steel roller conveyor belt group 202 and the second steel roller conveyor belt group 203 are driven to rotate through the first transmission belt 204 and the second transmission belt 205. The shovel 206 will shovel out the Codonopsis buried in the soil and use the first steel roller conveyor belt group 202 and the second steel roller conveyor belt group 203 to move along the inside of the frame 1. When the extrusion piece 401 is installed inside the frame 1, along with the operation of the transmission 201, the rotating disk 301 will rotate synchronously, and at the same time, the elastic piece 305 will be driven to rotate synchronously through the telescopic rod 304, and the synchronously rotating elastic piece 305 will drive the cylindrical structure composed of the brush steel rollers 303 to rotate. Along with the rotation of the cylindrical structure composed of the brush steel rollers 303, the first spring piece 3052 between the two upper brush steel rollers 303 will be squeezed by the extrusion piece 401, thereby expanding and deforming, pushing the two brush steel rollers 303 along the first ring The inside of the groove 302 moves in the opposite direction, causing the gap between the two brush steel rollers 303 located above to increase. As the rotating disk 301 continues to rotate, the two brush steel rollers 303 that have lost the extrusion of the extrusion member 401 will be pulled by the first spring piece 3052 to reset and move. In this way, in the cylindrical structure composed of a plurality of brush steel rollers 303, the gap between the two brush steel rollers 303 located above is always in an expanded state. At this time, the Codonopsis pilosula moving along the inside of the vehicle frame 1 will fall into the cylindrical structure composed of a plurality of brush steel rollers 303, and the brush steel rollers 303 will continue to roll with the Codonopsis pilosula and remove the soil adhered to the outer surface of the Codonopsis pilosula. The codonopsis pilosula is scraped off and transported toward the annular disk 306 until it is transported to the inside of the push plate conveyor belt group 502. As the transmission 201 is running, the push plate conveyor belt group 502 is started synchronously to drive the codonopsis pilosula to move and transport it to the inside of the collection box 503. When the extrusion member 401 is removed from the base 402, the operator needs to remove the back plate 403 at the same time. At this time, when the codonopsis pilosula falls to the top of the cylindrical structure composed of a plurality of brush steel rollers 303, the codonopsis pilosula cannot enter the inside of the cylindrical structure, and will be rolled by the brush steel roller 303 and fall from the end of the frame 1 into the field. The specific running trajectory is as follows Figure 3 shown.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
