Description

Technical Field

[0001] This invention relates to the field of harvesting equipment technology, and specifically to a peony harvesting device. Background Technology

[0002] Peony and herbaceous peony are commonly used rhizomes in traditional Chinese medicine and as ornamental flowers. The main medicinal and processing parts are their underground tuberous rhizomes. At the same time, during the growth of the plants, a large number of single, thin rhizomes with medicinal or propagation value are produced. With the development of large-scale and intensive planting bases, the harvesting process has become a key bottleneck restricting the improvement of the industry's quality and efficiency. For large-scale harvesting of peonies and herbaceous peonies, harvesting machines are generally used.

[0003] Most harvesters on the market are mainly designed for digging, sifting soil, and conveying. They can only achieve the initial separation of soil from large rhizomes. During operation, slender and lightweight single rhizomes are easily dropped back into the field with the soil or thrown out by the sifting machine. They cannot effectively collect single rhizomes while harvesting rhizomes. This not only wastes medicinal resources, but also requires manual secondary collection and harvesting, without fundamentally reducing labor intensity and harvesting time.

[0004] Therefore, a peony harvesting device is needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] This invention provides a peony harvesting device, which aims to solve the technical problem of not being able to collect individual rhizomes simultaneously.

[0006] A peony harvesting device of the present invention includes a frame and a rotating screen, the rotating screen being disposed inside the frame, and further includes: A vibrating screen frame is positioned below the rotating screen; The collecting mesh frame is connected to the end of the vibrating mesh frame. Two symmetrical sides of the collecting mesh frame are rotatably connected to connecting rods. The end of the connecting rod away from the collecting mesh frame is rotatably connected to the frame. At least one set of eccentric drive structures is arranged between the frame and the vibrating mesh frame. The eccentric drive structures are used to make the vibrating mesh frame and the collecting mesh frame swing up and down. The weeding structure is set on the frame and located above the vibrating net frame. The weeding structure is used to remove weeds on the vibrating net frame. The weeding structure includes two support rods connected to the frame. A rotating roller is rotatably connected to the two support rods. The rotating roller is located above the vibrating net frame. Multiple weed wrapping frames are evenly connected to the outer surface of the rotating roller. The cutting structure, connected to the support rod, is used to cut off the weeds wrapped around the grass wrapping frame; The top material structure is set on the support rod and located below the vibrating mesh frame. The top material structure is used to push out the single rootstock inserted inside the vibrating mesh frame.

[0007] Preferably, the top material structure includes a top material support frame, top material springs, and a top material frame. The top material support frame is connected to the support rod. Multiple top material springs are evenly distributed on one side of the top material support frame. The top ends of the multiple top material springs are connected to the top material frame. The gap between the top material frame and the vibrating mesh frame corresponds to the gap position.

[0008] Its effect is to push out single roots stuck in the gaps of the mesh frame, avoid root residue, and ensure smooth conveying.

[0009] Preferably, the cutting structure includes a support block, a lead screw, a moving frame, and a cutting blade. The support block is connected to a support rod, the lead screw is rotatably connected to the support block, the length direction of the lead screw is parallel to the length direction of the rotating roller, the moving frame is threadedly connected to the lead screw, and there is at least one cutting blade, the cutting blade being positioned corresponding to the grass wrapping frame.

[0010] Its effect is that the screw-driven moving frame moves the cutting blade horizontally, which can accurately cut the weeds on the grass-wrapping frame. It is easy to operate, facilitates quick weed removal, and ensures the continuous operation of the weeding structure.

[0011] Preferably, the eccentric drive structure includes a second rotating shaft, a turntable, a rotating rod, and a connecting rod. The second rotating shaft is rotatably mounted on the frame, one end of which is connected to the turntable, and the second rotating shaft and the turntable are concentrically arranged. The rotating rod is rotatably located at the edge of one side of the turntable. One end of the connecting rod is rotatably connected to the rotating rod, the other end of which is rotatably connected to the frame, and the middle part of the connecting rod is rotatably connected to the side of the frame.

[0012] Its effect is that, through the eccentric rotation of the turntable and the lever transmission of the connecting rod, the rotational motion is converted into the up-and-down swinging of the vibrating mesh frame, providing a stable vibration force for soil separation and root transport.

[0013] Preferably, a rotating shaft is rotatably connected to the frame, and a transmission structure is provided between the rotating shaft and an input shaft of the rotating screen. The transmission structure is used to make the rotating shaft rotate with the operation of the rotating screen. A transmission structure is provided between the rotating shaft and the rotating roller, and the transmission structure is used to make the rotating roller rotate synchronously with the rotation of the rotating shaft.

[0014] Its effects are as follows: by using transmission structure one and transmission structure two to achieve linkage between the rotating roller and the rolling screen, no additional drive source is required, energy consumption is reduced, the equipment structure is simplified, and the synchronous operation is guaranteed.

[0015] Preferably, a drive component is installed on the frame, and a transmission structure three is provided between the drive component and the rotating screen. The transmission structure three is used to make the rotating screen work with the work of the drive component. A transmission structure four is provided between the drive component and the rotating shaft two. The transmission structure four is used to make the rotating shaft two rotate with the work of the drive component.

[0016] Preferably, two guide rollers are rotatably arranged near the end of the excavator shovel on the frame. A rotating shaft three is arranged on the frame. A gear drive assembly is arranged between the rotating shaft three and the guide rollers. The gear drive assembly is used to drive the guide rollers to rotate with the rotating shaft three. A transmission structure five is arranged between the rotating shaft three and the drive component. The transmission structure five is used to make the rotating shaft three rotate with the operation of the drive component.

[0017] Its effect is to smoothly introduce the excavated rhizomes, avoid the accumulation and jamming at the feed inlet of the machine frame, and ensure the continuity of the harvesting process.

[0018] Preferably, the support rod is rotatably equipped with a movable wheel, and a trailer frame is connected to the frame.

[0019] Preferably, transmission structure one, transmission structure two, transmission structure three, transmission structure four and transmission structure five are all one type of chain drive or belt drive structure.

[0020] The beneficial effects of this invention are: 1. By setting a vibrating screen and a collecting screen below the rotating screen, and using an eccentric drive structure to achieve up-and-down swinging, it can separate individual rhizomes from the soil and automatically transport the individual rhizomes to the collecting screen. This solves the problem that individual rhizomes are easily dropped with the soil or thrown out by traditional harvesters, completely avoiding the waste of medicinal resources. At the same time, it eliminates the need for manual secondary picking and re-harvesting, greatly reducing labor intensity and harvesting time, and improving the harvesting efficiency of large-scale planting.

[0021] 2. By setting up a weeding structure, the rotating roller drives the weed wrapping frame to rotate and wrap the weeds. Combined with the cutting structure, it is easy to clean up the wrapped weeds, effectively reducing the amount of weeds mixed into the collection frame. At the same time, the top material structure can push out individual roots stuck in the gaps of the vibrating frame, avoiding root residue and ensuring higher purity of collected individual roots. Subsequent sorting and processing operations are simpler, improving the overall processing efficiency of the industry. Attached Figure Description

[0031] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] like Figures 1 to 8 As shown, a peony harvesting device of the present invention includes a frame 10, with a digging shovel connected to one end of the frame 10. A rotating screen 20 is installed inside the frame 10, and a vibrating screen frame 30 is installed below the rotating screen 20. The vibrating screen frame 30 is used to collect single rhizomes that fall from the rotating screen 20. A collecting screen frame 31 is connected to one end of the vibrating screen frame 30. Connecting rods 32 are rotatably connected to two symmetrical sides of the collecting screen frame 31. The end of the connecting rod 32 away from the collecting screen frame 31 is rotatably connected to the frame 10. The frame 10... At least one set of eccentric drive structures is provided on the frame 10. The eccentric drive structures are connected to the vibrating mesh frame 30. The eccentric drive structures are used to make the vibrating mesh frame 30 and the collecting mesh frame 31 swing up and down to separate the soil and single rhizomes on the vibrating mesh frame 30 and transport the single rhizomes from the vibrating mesh frame 30 to the inside of the collecting mesh frame 31. A weeding structure is provided on the frame 10. The weeding structure is located above the vibrating mesh frame 30 and is used to remove weeds on the vibrating mesh frame 30 and reduce the weed content in the single rhizomes collected by the collecting mesh frame 31.

[0033] During the harvesting of peony or herbaceous peony rhizomes, a digging shovel enters the soil and excavates the rhizomes. The excavated rhizomes are then conveyed upwards by a rotating screen 20. During this conveying process, the rotating screen 20 separates the soil adhering to the rhizomes. A collection box or elevator can be connected to the end of the rotating screen 20. The collection box collects the rhizomes, or the elevator conveys them to the vehicle accompanying the harvesting device, thus completing the rhizome harvesting operation. Connecting a collection box or elevator to the end of the rotating screen 20 is an existing and mature technology, therefore it is not shown in the figure. During the process of conveying and screening the blocky rhizomes by the moving screen 20, individual rhizomes will fall onto the vibrating screen frame 30. With the swinging and vibration of the vibrating screen frame 30, the individual rhizomes on the vibrating screen frame 30 are separated from the soil. The individual rhizomes separated from the soil are then conveyed into the collection screen frame 31, thereby completing the automatic harvesting operation of the individual rhizomes. During the process of separating the individual rhizomes from the soil, the weeding structure will collect weeds, reducing the amount of weeds entering the collection screen frame 31, so that the collected individual rhizomes have fewer impurities, which makes the subsequent collection of individual rhizomes easier.

[0034] like Figures 1 to 4 and Figures 6 to 8 The weeding structure includes two support rods 40 connected to the frame 10. A rotating roller 41 is rotatably connected to the two support rods 40. The rotating roller 41 is located above the vibrating screen frame 30. Multiple weed wrapping frames 42 are evenly connected to the outer surface of the rotating roller 41. The weed wrapping frames 42 are used to wrap weeds. A transmission assembly is provided between the frame 10, the rotating roller 41 and the rotating screen 20. The transmission assembly is used to make the rotating roller 41 rotate with the operation of the rotating screen 20. A cutting structure is connected to the support rods 40. The cutting structure is used to cut the weeds wrapped by the weed wrapping frames 42, so that the operation of cleaning the weeds wrapped by the weed wrapping frames 42 is relatively simple.

[0035] The rotating roller 41 rotates under the drive of the transmission component, which drives the grass wrapping frame 42 to rotate. The grass wrapping frame 42 extends into the area above the vibrating net frame 30, wrapping and removing the weeds mixed in the roots and stems. When the harvesting work is completed or when there are too many weeds wrapped on the grass wrapping frame 42, the harvesting work is stopped. At this time, the weeds wrapped on the grass wrapping frame 42 can be cut off by the cutting structure, which facilitates quick cleaning.

[0036] The cutting structure includes a support block 43 connected to the support rod 40. A lead screw 44 is rotatably connected to one side of the support block 43. A turntable is connected to the end of the lead screw 44. A movable frame 45 is threaded onto the outer surface of the lead screw 44. At least one cutting blade 46 is connected to the side of the movable frame 45 near the grass wrapping frame 42. The cutting blade 46 is positioned corresponding to the grass wrapping frame 42. The maximum distance between the axis of the rotating roller 41 and the grass wrapping frame 42 is less than the minimum distance between the center of the rotating roller 41 and the lead screw 44, so as to avoid interference between the grass wrapping frame 42 and the lead screw 44 during rotation.

[0037] The length of the lead screw 44 is greater than the length of the grass wrapping frame 42. In the initial state, the cutting blade 46 is located at the end of the lead screw 44. At this time, the grass wrapping frame 42 will not interfere with the cutting blade 46 during rotation. The rotating turntable drives the lead screw 44 to rotate, causing the moving frame 45 and the cutting blade 46 to move along the lead screw 44. The cutting blade 46 approaches and cuts the weeds wrapped on the grass wrapping frame 42, which makes it easier for personnel to clean up the weeds and ensures that the weeding structure works continuously and effectively.

[0038] A guide plate is fixedly connected to one side of the support rod 40, and a guide rod is fixedly connected to one side of the guide plate. The length direction of the guide rod is parallel to the length direction of the rotating roller 41. The guide rod passes through the movable frame 45, and the movable frame 45 is slidably connected to the guide rod. The guide rod guides the movable frame 45 so that the movable frame 45 moves smoothly along the length direction of the guide rod.

[0039] The transmission assembly includes a rotating shaft 47 rotatably connected to the frame 10, a transmission structure 48 between the rotating shaft 47 and an input shaft of the rotary screen 20, the transmission structure 48 being used to make the rotating shaft 47 rotate with the operation of the rotary screen 20, and a transmission structure 49 between the rotating shaft 47 and the rotary roller 41, the transmission structure 49 being used to make the rotary roller 41 rotate synchronously with the rotation of the rotating shaft 47.

[0040] When the rotary screen 20 is in operation, the first shaft 47 is driven to rotate through the first transmission structure 48. The first shaft 47 then transmits power to the rotating roller 41 through the second transmission structure 49, so that the rotating roller 41 and the rotary screen 20 operate in conjunction, without the need to set up a separate drive source for the weeding structure.

[0041] like Figures 1 to 7 A top-feeding structure is connected to the support rod 40. The top-feeding structure is located below the vibrating mesh frame 30. The top-feeding structure is used to push out the single root inserted inside the vibrating mesh frame 30 to avoid the single root remaining on the vibrating mesh frame 30. This allows the single root on the vibrating mesh frame 30 to smoothly enter the collection mesh frame 31. The top-feeding structure includes a top-feeding support frame 50 connected to the support rod 40. Multiple top-feeding springs 51 are fixedly connected to one side of the top-feeding support frame 50. A top-feeding frame 52 is fixedly connected to the top of the multiple top-feeding springs 51. The top-feeding frame 52 is provided with a top-feeding groove for soil to fall. The gap position of the top-feeding frame 52 corresponds to that of the vibrating mesh frame 30, which makes the effect of pushing out the single root inserted in the gap position of the vibrating mesh frame 30 better.

[0042] When the rotary screen 20 is screening the blocky rhizomes, a single rhizome may fall vertically from the rotary screen 20 and insert into the gap of the vibrating screen frame 30. When the vibrating screen frame 30 swings up and down, the top material frame 52 pushes the stuck single rhizome upward from the gap of the screen frame to prevent the rhizome from blocking the gap of the screen frame. In addition, the top material spring 51 can deform when the top material frame 52 comes into contact with the vibrating screen frame 30, and make the top material frame 52 fit with the vibrating screen frame 30, thereby better pushing out the single rhizome on the vibrating screen frame 30. After the vibrating screen frame 30 separates from the top material frame 52, the top material frame 52 will be reset under the reaction force of the top material spring 51. The top material trough can allow soil to fall without affecting the soil screening, ensuring that the single rhizome is smoothly conveyed to the collection screen frame 31.

[0043] like Figures 1 to 3 The eccentric drive structure includes a rotating shaft 60 rotatably mounted on the frame 10. A turntable 61 is connected to the end of the rotating shaft 60. A rotating rod 62 is rotatably connected to one edge of the turntable 61. A connecting rod 63 is rotatably connected to the end of the rotating rod 62 away from the turntable 61. The middle part of the connecting rod 63 is rotatably connected to the side of the frame 10. The end of the connecting rod 63 away from the rotating rod 62 is rotatably connected to the vibrating mesh frame 30.

[0044] The rotating shaft 60 drives the turntable 61 to rotate, and the rotating rod 62 on the turntable 61 makes eccentric motion. Through the lever transmission of the connecting rod 63 and the rotation of the connecting rod 32, the rotational motion is converted into the up and down swing of the vibrating mesh frame 30, which provides vibration force for soil separation and rhizome transportation, so that a single rhizome can move towards the collection mesh frame 31.

[0045] like Figures 1 to 3 A drive component 11 is installed on the frame 10. A transmission structure 3 12 is provided between the drive component 11 and the rotating screen 20. The transmission structure 3 12 is used to make the rotating screen 20 work with the work of the drive component 11. A transmission structure 4 13 is provided between the drive component 11 and the rotating shaft 2 60. The transmission structure 4 13 is used to make the rotating shaft 2 60 rotate with the work of the drive component 11.

[0046] The drive component 11 provides power to the whole machine, drives the rotating screen 20 to operate through the transmission structure 3 12, and drives the rotating shaft 2 60 to rotate through the transmission structure 4 13, so that the rotating screen 20 and the eccentric drive structure are driven by the same power source, ensuring synchronous movement and compact structure.

[0047] Two guide rollers 14 are rotatably installed at the end of the frame 10 near the digging shovel. The rotation of the two guide rollers 14 allows the peony or peony root to move smoothly onto the rotating screen 20. A rotating shaft 15 is installed on the frame 10. A gear drive assembly is installed between the rotating shaft 15 and the guide rollers 14. The gear drive assembly is used to drive the guide rollers 14 to rotate with the rotating shaft 15. A transmission structure 16 is installed between the rotating shaft 15 and the drive component 11. The transmission structure 16 is used to make the rotating shaft 15 rotate with the operation of the drive component 11.

[0048] The drive unit 11 drives the rotating shaft 15 to rotate through the transmission structure 16. The rotating shaft 15 drives the guide roller 14 to rotate through the gear drive assembly. The guide roller 14 smoothly and steadily guides the roots dug out by the digging shovel into the rotating screen 20, avoiding the accumulation or jamming of roots at the feeding position and ensuring continuous and stable feeding.

[0049] Transmission structures 1 (48), 2 (49), 3 (12), 4 (13), and 5 (16) are all types of chain drive or belt drive structures. Each of these structures is equipped with a protective cover (not shown in the figure) to prevent external factors from affecting them, ensuring stable transmission and extending the service life of the transmission structures.

[0050] Both support rods 40 are connected to movable wheels 70, and a trailer frame 71 is connected to the frame 10. The trailer frame 71 is connected to a vehicle body such as a tractor, and the movable wheels 70 enable the harvesting device to move smoothly.
