Description

Technical Field

[0001] The present invention relates to the technical field of traditional Chinese medicine harvesting equipment, and particularly relates to a Codonopsis pilosula harvester. Background Art

[0002] Codonopsis pilosula is a unique traditional Chinese medicine material in China. As a commonly used traditional Chinese medicine, its source is the dried roots of Codonopsis pilosula, Codonopsis pilosula var. modesta, or Codonopsis tangshen, etc. Codonopsis pilosula is sweet in taste and neutral in nature, and has the functions of tonifying the middle-Jiao and replenishing qi, quenching thirst, strengthening the spleen and benefiting the lungs, nourishing blood and promoting fluid production. It is used for symptoms such as qi deficiency of the spleen and lungs, anorexia and lassitude, cough with deficiency asthma, insufficient qi and blood, sallow complexion, palpitation and shortness of breath, thirst due to fluid impairment, internal heat and polydipsia, listlessness and shortness of breath, weakness of the limbs, poor appetite, qi deficiency, deficiency of both qi and fluid, deficiency of both qi and blood, and sallow complexion due to blood deficiency. The efficacy of this product is similar to that of ginseng, but the medicinal power is weaker.

[0003] Publication (Announcement) Number: CN117480930A, which discloses a deep-rooted traditional Chinese medicine harvesting machine. The device includes: a frame, a digging device arranged at the bottom of the front end of the frame, a feeding device arranged inside the frame, the feeding end corresponding to the digging device, a screening device arranged inside the frame and located at the rear end of the feeding device, a power transmission system arranged on the frame, which sequentially transmits power to the feeding device and the screening device, and two ground wheels respectively arranged on both sides of the rear of the frame. Among them, the feeding device includes: a first-stage feeding roller horizontally arranged inside the frame and located at the rear end of the digging device, a second-stage feeding roller horizontally arranged inside the frame and located at the rear end of the first-stage feeding roller, and the second-stage feeding roller is connected to the first-stage feeding roller through a transmission component.

[0004] In order to improve work efficiency, automated machinery is used for harvesting mature Codonopsis pilosula in the existing market. However, when the traditional Codonopsis pilosula harvester is actually operating, it only has a preliminary soil crushing function for Codonopsis pilosula, and cannot further separate the soil adhering to the surface of Codonopsis pilosula, resulting in the need for further surface fine cleaning treatment after harvesting Codonopsis pilosula, increasing the harvesting cost of Codonopsis pilosula; at the same time, the traditional Codonopsis pilosula harvester cannot control the storage position of the harvested Codonopsis pilosula in a timely manner according to the needs of the operator (either stacking it in a collection box or directly spreading it on the ground), so it has limitations in use. Summary of the Invention

[0005] The present invention discloses a Codonopsis pilosula harvester, aiming to solve the technical problems that in the actual operation of the traditional Codonopsis pilosula harvester in the existing market, it only has a rough soil crushing function for Codonopsis pilosula, resulting in the need for further surface fine cleaning treatment after harvesting Codonopsis pilosula, increasing the harvesting cost of Codonopsis pilosula; at the same time, the traditional Codonopsis pilosula harvester cannot control the storage position of the harvested Codonopsis pilosula in a timely manner according to the needs of the operator, and also has limitations in use.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] A Codonopsis pilosula harvester, comprising a vehicle frame, and a harvesting mechanism for de-soiling Codonopsis pilosula is arranged at one end inside the vehicle frame;

[0008] A reprocessing mechanism for re-de-soiling the surface of Codonopsis pilosula is arranged at the other end inside the vehicle frame. The reprocessing mechanism includes a rotating disk rotatably installed on one side inside the vehicle frame. A first annular groove is formed on the rotating disk, and a plurality of uniformly arranged brush steel rollers are distributed inside the first annular groove. The end of the brush steel roller is slidably installed inside the first annular groove;

[0009] A switching mechanism for changing the running mode of the vehicle frame is arranged on the side of the reprocessing mechanism. The switching mechanism includes a pressing member, and the pressing member penetrates through the middle of the rotating disk;

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

[0011] Through the cooperation of the harvesting mechanism and the movement of the vehicle frame, the Codonopsis pilosula is de-soiled from the ground. At the same time, the Codonopsis pilosula after leaving the ground will enter the reprocessing mechanism for surface de-soiling treatment. By disassembling and installing the switching mechanism and cooperating with the operation of the collecting mechanism, two running modes of centrally stacking the de-soiled Codonopsis pilosula and directly spreading it in the field can be realized.

[0012] By arranging a harvesting mechanism inside the vehicle frame, the Codonopsis pilosula buried in the soil is de-soiled from the ground by using the cooperation of the harvesting mechanism and the movement of the vehicle frame. At the same time, the Codonopsis pilosula after leaving the ground will enter the reprocessing mechanism for surface de-soiling treatment, so as to directly complete the detachment treatment of the soil adhered to the surface of the Codonopsis pilosula during the harvesting of Codonopsis pilosula, improving the quality of Codonopsis pilosula during harvesting. By disassembling and installing the additionally arranged switching mechanism, it can cooperate with the operation of the collecting mechanism to realize two running modes of centrally stacking the de-soiled Codonopsis pilosula and directly spreading it in the field, thereby improving the functionality and working efficiency of the traditional Codonopsis pilosula harvester.

[0013] In a preferred solution, the harvesting mechanism includes a transmission installed inside the vehicle frame. The output end of the transmission penetrates through the side of the vehicle frame. A first steel roller conveyor belt group and a second steel roller conveyor belt group are rotatably installed inside the vehicle frame. The first steel roller conveyor belt group and the second steel roller conveyor belt group are distributed horizontally in a staggered manner. At the same time, a first transmission belt is sleeved between the output end of the transmission and the second steel roller conveyor belt group, and a second transmission belt is also sleeved 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 vehicle frame, and the shovel plate is distributed at one end of the first steel roller conveyor belt group.

[0014] By arranging a first steel roller conveyor belt group and a second steel roller conveyor belt group driven by a transmission inside the frame, and coordinating with the movement of the frame along the field, the shovel plate is inserted into the soil, and the codonopsis pilosula mixed with soil is carried to the tops of the first steel roller conveyor belt group and the second steel roller conveyor belt group. The rotating first steel roller conveyor belt group and second steel roller conveyor belt group are used to complete the screening of the codonopsis pilosula, so as to separate the codonopsis pilosula from the soil and complete the harvesting work of the codonopsis pilosula, ensuring the rationality of the realization of the equipment function.

[0015] In a preferred solution, a number of uniformly distributed telescopic rods are installed inside the rotating disk. The ends of the number of telescopic rods are jointly connected with an elastic member. The elastic member is sleeved outside the ends of the number of brush steel rollers. An annular disk is installed on the other side inside the frame. The other ends of the number of brush steel rollers are slidably installed inside the annular disk.

[0016] By arranging a number of brush steel roller structures slidably installed inside the rotating disk, the rotating disk drives the brush steel rollers to perform synchronous revolution. At the same time, the brush steel rollers are connected by the elastic member. The elastic member between the upper two groups of brush steel rollers will be squeezed by the switching mechanism and deformed, and then push the corresponding brush steel roller to move, so that the codonopsis pilosula falling from the second steel roller conveyor belt group can enter the inside of the number of brush steel rollers through the gaps between the brush steel rollers. Thus, with the revolution of the brush steel rollers, the secondary soil removal treatment of the surface of the codonopsis pilosula is completed, thereby greatly improving the harvesting quality of the equipment.

[0017] In a preferred solution, the switching mechanism further includes a base fixedly installed on the outside of the frame. A threaded rod is fixed on the side of the pressing member away from the brush steel roller. The threaded rod passes through the base and is connected by a nut. The top of the pressing member is in pressing contact with the elastic member. A back plate is installed at the end of the frame and near the reprocessing mechanism. An inclined plate is fixed on the side surface of the back plate.

[0018] By arranging a pressing member structure threadedly installed on the base and cooperating with the rotation of the rotating disk, the top of the elastic member is pressed, so as to complete the adjustment work of the gap between the upper two groups of brush steel rollers. Cooperating with the operation of the collection mechanism, the processed codonopsis pilosula can be collected. At the same time, when the operator disassembles the pressing member and the back plate together according to the needs, at this time, the number of brush steel rollers rotating with the rotating disk only has the function of crushing soil for the codonopsis pilosula, and the crushed codonopsis pilosula is thrown to the field through the position of the original back plate at the end of the frame, so as to control the falling point of the harvested codonopsis pilosula according to the needs and improve the functionality of the traditional codonopsis pilosula harvester.

[0019] In a preferred embodiment, the collection mechanism includes a collection bin installed on the side of the vehicle frame. A push plate conveyor belt group is rotatably installed inside the collection bin. A collection box is installed on the top of the vehicle frame, and the collection bin is docked with the collection box.

[0020] By providing a push plate conveyor belt group driven by a transmission to transport the codonopsis pilosula that falls out of the annular plate and convey it into the collection box, the centralized stacking of codonopsis pilosula is realized, improving the perfection of the operation of this equipment.

[0021] In a preferred embodiment, the elastic member includes a number of connecting sleeves sleeved on the ends of the brush steel rollers. The connecting sleeves are connected to each other by first elastic sheets, and the pressing member is in pressing contact with the first elastic sheets.

[0022] By providing a structure of a number of connecting sleeves sleeved outside the brush steel rollers, the connecting sleeves are connected to each other by first elastic sheets. Using the extrusion and pushing of the first elastic sheets by the pressing member, the first elastic sheets are deformed, thereby pushing the connecting sleeves and the brush steel rollers to move along the inside of the first annular groove, so as to adjust the distance between the two brush steel rollers at the top, allowing the codonopsis pilosula to fall into the cylindrical structure composed of a number of brush steel rollers, ensuring the perfection of the operation of this equipment.

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

[0024] First: By providing a first steel roller conveyor belt group and a second steel roller conveyor belt group driven by a transmission inside the vehicle frame, and cooperating with the movement of the vehicle frame along the field, the codonopsis pilosula mixed with soil is carried to the tops of the first steel roller conveyor belt group and the second steel roller conveyor belt group by inserting the shovel plate into the soil, and the preliminary screening of the codonopsis pilosula is completed by using the rotating first steel roller conveyor belt group and second steel roller conveyor belt group, so as to screen the codonopsis pilosula out of the soil. At the same time, by additionally providing a structure of a number of brush steel rollers slidably installed inside the rotating disk, the elastic member is driven to revolve by the rotating disk, and the brush steel rollers rotate synchronously due to the connection of the elastic member. At this time, the elastic member between the two brush steel rollers directly above will be squeezed by the switching mechanism, so as to deform and push the corresponding two brush steel rollers to move, so that the codonopsis pilosula falling from the second steel roller conveyor belt group can enter the inside of the cylindrical structure composed of a number of brush steel rollers through the gaps between the brush steel rollers, and along with the revolution of the brush steel rollers, the secondary soil removal treatment of the surface of the codonopsis pilosula is completed, thus greatly improving the harvesting quality and efficiency of this equipment.

[0025] Second: By setting an extrusion part structure installed on the base with threads and cooperating with the rotation of the rotating disk, the top of the elastic part is extruded, thereby completing the adjustment of the gap between the two sets of brush steel rollers at the top. The operation of the push plate conveyor belt group can centrally stack the processed codonopsis pilosula into the collection box. At the same time, when the operator disassembles the extrusion part and the back plate according to requirements, several brush steel rollers rotating with the rotating disk form a stable cylindrical structure at this time, making it impossible for the codonopsis pilosula to enter between the several brush steel rollers. Therefore, the codonopsis pilosula only has the function of crushing soil, and the crushed codonopsis pilosula is thrown to the field through the end of the vehicle frame at the original position of the back plate, enabling this codonopsis pilosula harvester to control the dropping point of the harvested codonopsis pilosula according to requirements (stored in the collection box or directly thrown into the field), thereby improving the functionality of the traditional codonopsis pilosula harvester.

[0040] 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.

[0041] A Codonopsis pilosula harvester disclosed by the present invention is mainly applied to the scenario of Codonopsis pilosula harvesting.

[0042] Refer to Figures 1 to 13 , a Codonopsis pilosula harvester, including a frame 1, and a harvesting mechanism 2 for removing soil from Codonopsis pilosula is arranged at one end inside the frame 1;

[0043] At the other end inside the frame 1, a re-processing mechanism 3 for re-removing soil from the surface of Codonopsis pilosula is arranged. The re-processing mechanism 3 includes a rotating disc 301 rotatably installed on one side inside the frame 1. A first annular groove 302 is formed on the rotating disc 301, and 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 installed inside the first annular groove 302;

[0044] A switching mechanism 4 for changing the running mode of the frame 1 is arranged on the side of the re-processing mechanism 3. The switching mechanism 4 includes an extrusion piece 401, and the extrusion piece 401 penetrates through the middle of the rotating disc 301;

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

[0046] Through the cooperation of the harvesting mechanism 2 and the movement of the vehicle frame 1, the codonopsis pilosula is removed from the soil above the ground. At the same time, the codonopsis pilosula after being lifted off the ground will enter the internal of the reprocessing mechanism 3 for surface soil removal treatment. And through the cooperation of the disassembly and assembly switching mechanism 4 and the operation of the collection mechanism 5, two operation modes can be realized, namely, centrally stacking the codonopsis pilosula after soil removal and directly spreading it in the field.

[0047] In this embodiment: Before use, the operator docks the vehicle frame 1 with an agricultural tractor, starts the tractor to drive the vehicle frame 1 to move to the codonopsis pilosula field. At the same time, the vehicle frame 1 is pushed to tilt by an external hydraulic device, and the harvesting mechanism 2 is inserted into the soil. At this time, the operator controls the tractor to move along the field. While moving, the harvesting mechanism 2 will shovel out the codonopsis pilosula buried in the soil and convey it along the inside of the vehicle frame 1. While conveying, the codonopsis pilosula is separated from large pieces of soil, sand and gravel. When the switching mechanism 4 is assembled inside the vehicle frame 1, the codonopsis pilosula moving along the inside of the vehicle frame 1 will fall into the internal of the reprocessing mechanism 3. The reprocessing mechanism 3 drives the codonopsis pilosula to continuously roll and scrape off the soil adhering to the outer surface of the codonopsis pilosula, and at the same time conveys the codonopsis pilosula to the internal of the collection mechanism 5 for centralized stacking; when the switching mechanism 4 inside the vehicle frame 1 is disassembled, at this time, the codonopsis pilosula conveyed along the inside of the vehicle frame 1 will cross over from the outside of the reprocessing mechanism 3 and fall into the field, and the rotating reprocessing mechanism 3 colliding with the codonopsis pilosula only plays a role in crushing the soil on the surface of the codonopsis pilosula.

[0048] Among them, it should be supplemented and explained that: A number of uniformly distributed reinforcing rods 207 are fixedly installed at the bottom of the vehicle frame 1, and the structural strength of the vehicle frame 1 is improved through the reinforcing rods 207.

[0049] In the above solution, considering that in order to strip the codonopsis pilosula from the muddy land, the specific operation is as follows.

[0050] Refer to Figures 1 to 5 , in a preferred embodiment, the harvesting mechanism 2 includes a transmission 201 installed inside the vehicle frame 1. The output end of the transmission 201 penetrates out from the side of the vehicle frame 1. A first steel roller conveyor belt group 202 and a second steel roller conveyor belt group 203 are rotatably installed inside the vehicle frame 1. The first steel roller conveyor belt group 202 and the second steel roller conveyor belt group 203 are distributed in a horizontal offset manner. At the same time, a first transmission belt 204 is sleeved between the output end of the transmission 201 and the second steel roller conveyor belt group 203, and a second transmission belt 205 is sleeved 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 vehicle 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 to move the frame 1 to the field of Codonopsis pilosula, and at the same time pushes the frame 1 to tilt through an external hydraulic device, inserts the shovel plate 206 into the soil. At this time, the operator controls the tractor to move along the field. While moving, the transmission 201 starts and drives the first steel roller conveyor belt group 202 and the second steel roller conveyor belt group 203 to rotate through the first conveyor belt 204 and the second conveyor belt 205. The shovel plate 206 will shovel out the Codonopsis pilosula buried in the soil and convey it along the inside of the frame 1 by using the first steel roller conveyor belt group 202 and the second steel roller conveyor belt group 203. While conveying, the Codonopsis pilosula is separated from the large pieces of soil, sand and gravel.

[0052] Among them, the transmission 201 is connected to the rear output shaft of the tractor and is used for driving rotation.

[0053] In the above solution, considering that in order to further strip the soil adhering to the surface of the Codonopsis pilosula, the specific operation is as follows.

[0054] Refer to Figures 3 to 5 、 Figures 7 to 11 , in a preferred embodiment, several uniformly distributed telescopic rods 304 are installed inside the rotating disk 301. The ends of the several telescopic rods 304 are commonly connected to an elastic member 305. The elastic member 305 is sleeved outside the ends of the several brush steel rollers 303. On the other side inside the frame 1, an annular disk 306 is installed. The other ends of the several brush steel rollers 303 are slidably installed inside the annular disk 306.

[0055] In this embodiment: When the switching mechanism 4 is assembled inside the frame 1, along with the operation of the transmission 201, the rotating disk 301 will rotate synchronously. While rotating, the elastic member 305 is driven to rotate synchronously through the telescopic rod 304, and the synchronously rotating elastic member 305 will drive the several brush steel rollers 303 to rotate. Along with the rotation of the several brush steel rollers 303, when the elastic member 305 between the two upper brush steel rollers 303 is squeezed, it will deform (such as Figure 9As shown in the figure), the two brush steel rollers 303 are driven to move in opposite directions 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 lose the extrusion 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 several brush steel rollers 303, the distance between the two upper brush steel rollers 303 is always in an enlarged state. At this time, the codonopsis pilosula moving along the inside of the vehicle frame 1 will fall into the cylindrical structure composed of several brush steel rollers 303. The brush steel rollers 303 drive the codonopsis pilosula to roll continuously and scrape off the soil adhering to the outer surface of the codonopsis pilosula, and at the same time convey the codonopsis pilosula towards the direction of the annular disk 306 until the codonopsis pilosula is conveyed into the inside of the collection mechanism 5 for centralized stacking; among them, a third transmission belt 308 is sleeved 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. The ends of adjacent two brush steel rollers 303 are connected with a second elastic piece 307, and the second elastic piece 307 is located in the second annular groove on one side of the annular disk 306. The ends of each brush steel roller 303 are elastically connected through the second elastic piece 307 to ensure the structural stability and prevent a single brush steel roller 303 from shaking during the rotation of the cylindrical structure composed of brush steel rollers 303; and the entire reprocessing mechanism 3 is inclined towards the collection mechanism 5.

[0056] Further, the elastic member 305 includes several connecting sleeves 3051 sleeved on the ends of the brush steel rollers 303. The connecting sleeves 3051 are connected to each other through the first elastic pieces 3052, and the pressing member 401 is in pressing contact with the first elastic pieces 3052; when the rotating disk 301 rotates, the elastic member 305 is driven to rotate synchronously through the telescopic rod 304 while rotating, and the synchronously rotating elastic member 305 will drive the cylindrical structure composed of several brush steel rollers 303 to rotate. Along with the rotation of the cylindrical structure composed of brush steel rollers 303, when the first elastic piece 3052 between the two upper brush steel rollers 303 is squeezed, it will deform outward, so as to use the connecting sleeve 3051 to drive the two brush steel rollers 303 to move in opposite directions 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 lose the extrusion of the switching mechanism 4 will be pulled by the first elastic piece 3052 to reset and move.

[0057] In the above solution, considering that it is convenient for users to change the stacking position of the harvested codonopsis pilosula according to their needs, the specific operation is as follows.

[0058] Refer to Figure 2 、 Figures 7 to 9, in a preferred embodiment, the switching mechanism 4 further includes a base 402 fixedly installed on the outer side of the vehicle frame 1. A threaded rod 4011 is fixed to 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 vehicle frame 1 and near the reprocessing mechanism 3, and an inclined plate 4031 is fixed to the side surface of the back plate 403.

[0059] In this embodiment: When the extrusion member 401 is assembled inside the vehicle frame 1, with the operation of the transmission 201, the rotating disk 301 will rotate synchronously. While rotating, the elastic member 305 is driven to rotate synchronously through the telescopic rod 304, and the elastic member 305 that rotates synchronously 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, when the elastic member 305 between the two upper brush steel rollers 303 is squeezed by the extrusion member 401, it will deform outward, pushing the two brush steel rollers 303 to move in opposite directions along the inside of the first annular groove 302, resulting in an increase in the gap between the two upper brush steel rollers 303; When the user rotates the nut 4012 and the threaded rod 4011 and removes the extrusion member 401 from the base 402, the operator needs to remove the back plate 403 together. 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 vehicle frame 1 to the field. The specific running track is as Figure 3 shown.

[0060] Among them, it should be supplemented that: When the extrusion member 401 is separated from the uppermost telescopic rod 304 and before contacting the next telescopic rod 304, there is a chance that the codonopsis pilosula that falls during this period cannot enter the cylindrical structure composed of the brush steel rollers 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 rollers 303 until the codonopsis pilosula enters the cylindrical structure composed of the brush steel rollers 303. Since the lower end of the inclined plate 4031 is in a non-contact state with the brush steel roller 303, there is a gap between the lower end of the inclined plate 4031 and the cylindrical structure composed of the brush steel rollers 303. In order to prevent the codonopsis pilosula or impurities from possibly falling into the gap between the back plate 403 and the brush steel rollers 303 through this gap, a brush structure is provided at the end of the inclined plate 4031 to flexibly block this gap, ensuring that the codonopsis pilosula fully falls into the cylindrical structure composed of the brush steel rollers 303 and preventing material jamming.

[0061] Further, as 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 to 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, Figure 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 vehicle frame 1 with the agricultural tractor, starts the tractor to drive the vehicle frame 1 to move to the field of Codonopsis pilosula, and at the same time pushes the vehicle frame 1 to tilt through an external hydraulic device, inserts the shovel plate 206 into the soil. At this time, the operator controls the tractor to move along the field. While moving, the transmission 201 starts, and drives the first steel roller conveyor belt group 202 and the second steel roller conveyor belt group 203 to rotate through the first conveyor belt 204 and the second conveyor belt 205. The shovel plate 206 will shovel out the Codonopsis pilosula buried in the soil and convey it along the inside of the vehicle frame 1 by using the first steel roller conveyor belt group 202 and the second steel roller conveyor belt group 203. While conveying, the Codonopsis pilosula is separated from large pieces of soil, sand and gravel. When the extrusion part 401 is assembled inside the vehicle frame 1, along with the operation of the transmission 201, the rotating disc 301 will rotate synchronously. While rotating, the elastic part 305 is driven to rotate synchronously through the telescopic rod 304. And the elastic part 305 that rotates synchronously 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 elastic piece 3052 between the two upper brush steel rollers 303 will be extruded by the extrusion part 401, so as to expand and deform, and push the two brush steel rollers 303 to move reversely along the inside of the first annular groove 302, resulting in an increase in the gap between the two upper brush steel rollers 303. And along with the continuous rotation of the rotating disc 301, the two brush steel rollers 303 that lose the extrusion of the extrusion part 401 will be pulled by the first elastic piece 3052 and thus reset and move. In this way, in the cylindrical structure composed of several brush steel rollers 303, the distance between the two upper brush steel rollers 303 is always in an enlarged state. At this time, the Codonopsis pilosula moving along the inside of the vehicle frame 1 will fall into the cylindrical structure composed of several brush steel rollers 303. The brush steel rollers 303 drive the Codonopsis pilosula to continuously roll and scrape off the soil adhering to the outer surface of the Codonopsis pilosula, and at the same time convey the Codonopsis pilosula towards the direction of the annular disc 306 until the Codonopsis pilosula is conveyed into the inside of the push plate conveyor belt group 502. And along with the operation of the transmission 201, the push plate conveyor belt group 502 starts synchronously, drives the Codonopsis pilosula to move and centrally convey it into the inside of the collection box 503; and when the extrusion part 401 is removed from the base 402, the operator needs to remove the back plate 403 together. At this time, when the Codonopsis pilosula 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 vehicle frame 1 to the field. The specific running track is as Figure 3 shown.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
