Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, specifically to an angelica harvester. Background Technology

[0002] Angelica dahurica is a tall perennial herb, with its roots used medicinally. The roots are cylindrical, and the base of the stem is 2-5 cm in diameter. It has functions such as dispelling dampness and dampness, draining pus and promoting tissue regeneration, and promoting blood circulation and relieving pain. It generally grows under forests, forest edges, streamsides, thickets, and mountain valley grasslands. When harvesting, the above-ground parts are usually cut off first, then the roots are dug up, the soil is shaken off, and they are transported to the drying yard for processing to complete the harvest.

[0003] Existing harvesting methods include manual harvesting, manual harvesting combined with machinery, and fully mechanized harvesting. Among these, manual harvesting is inefficient. Manual harvesting, which involves harvesters digging up the angelica and then picking it up and recycling it manually, is also inefficient. In the existing fully mechanized harvesting method, since the excavated angelica is mixed with a large amount of soil, rollers are needed to break up the large soil clods. Because the angelica is large and varies in size, in order not to damage it, the gap between the rollers must be set to be larger than the width of the angelica. This results in a large number of soil clods after roller pressing being the same size as, or even larger than, some smaller angelica clods, making it impossible to effectively separate the soil clods from the angelica and reducing work efficiency. Utility Model Content

[0004] This invention provides an Angelica dahurica harvester to solve the problem that soil clods of similar size to Angelica dahurica are difficult to separate effectively.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] A harvester for Angelica dahurica includes a frame, a digging section and a screening section mounted on the frame, and a conveying section. The conveying section includes a conveying device located above the screening section and a clamping device mounted on the conveying device. The clamping device includes a plurality of lifting plates and movable plates mounted on the conveying device. The lifting plates include a lifting surface facing the conveying direction of the conveying device and a connecting surface away from the conveying direction of the conveying device. A thrust elastic element is mounted on the connecting surface, and the movable plate is mounted on the thrust elastic element. Fasteners for fixing are mounted on the movable plate.

[0007] This invention uses a clamping device on a conveying device to transport angelica that has been screened by the screening department. During the conveying process, the movable plate is pushed by a thrust elastic element to impact the angelica or soil clods on the lifting plate, which can break the soil clods or crush the soil clods attached to the angelica, thereby further cleaning the soil clods and reducing the soil content in the harvested angelica.

[0008] Furthermore, the fastener includes limiting grooves fixedly installed on both sides of the lifting plate, and the limiting grooves match the lower end of the movable plate.

[0009] Since the thrust elastic element provides thrust to the movable plate, in order to keep the movable plate stable when it is not in operation, the movable plate is limited by the limiting groove, so that the thrust of the thrust elastic element is accumulated and released when the lower end of the movable plate leaves the limiting groove, forming an effective impact force and improving the effect of crushing soil clods.

[0010] Furthermore, the outer wall of the limiting groove on the side away from the supporting plate is designed as a slope. This facilitates the repositioning of the movable plate that has disengaged from the limiting groove.

[0011] Furthermore, a wedge-shaped body is provided below the moving path of the clamping device to allow the movable plate to disengage from the limiting groove, and a notch is provided at the lower end of the lifting plate for the wedge-shaped body to pass through.

[0012] The inclined surface of the wedge guides the movable plate, so that when the movable plate in the limiting groove passes the inclined surface of the wedge, the movable plate is lifted and gradually moves away from the limiting groove. Then, under the push of the thrust elastic element, it moves towards the lifting plate in front, which can impact and squeeze the angelica or soil clods lifted on the lifting plate, making it easier to clean the soil clods.

[0013] Furthermore, the moving path of the clamping device includes an upper clamping section and a lower reset section, with the wedge mounted on the clamping section.

[0014] Since the conveying device needs to rotate repeatedly, a conveyor belt structure is adopted. In order to transport the angelica in the screening section to the collection device or transfer device, such as the storage box of the harvester or an additional transport vehicle, the conveying device is preferably set to a horizontal or inclined upward state. Therefore, the angelica is clamped and transported by the clamping section above the conveying device, and the clamping device is reset by the reset section below.

[0015] Furthermore, a filter screen is provided below the clamping section from the wedge to one side of the screening section.

[0016] Similarly, since the conveying device is preferably set to a horizontal or inclined upward state, when the clamping device is not clamping the angelica, the filter screen lifts the angelica so that it is located inside the clamping device, making it easier for the clamping device to clamp it. The filter screen can also filter out small particles of soil.

[0017] Furthermore, a guide rod is provided between adjacent lifting plates, and a guide groove is provided on the movable plate, through which the guide rod passes.

[0018] Since the movable plate and the supporting plate are only connected by a thrust elastic element, the movable plate may be subject to lateral displacement. By using a guide rod to move and guide it, the lateral displacement of the movable plate can be prevented.

[0019] Furthermore, the width of the guide groove is equal to the diameter of the guide rod. This prevents the movable plate from shifting left or right during movement.

[0020] Furthermore, the length of the guide groove is greater than the diameter of the guide rod. This facilitates the vertical movement of the movable plate, allowing it to undergo a certain vertical displacement under the action of the inclined surface outside the wedge and the limiting groove, thus facilitating the movable plate's disengagement from or entry into the limiting groove.

[0021] Furthermore, a traction motor is installed on the lifting plate, and the traction end of the traction motor is connected to the movable plate.

[0022] The movable plate that has detached from the limiting groove is pulled back by a traction motor to facilitate the next clamping operation.

[0023] One or more technical solutions provided by this utility model have at least the following technical effects or advantages:

[0024] (1) This utility model transports the angelica that has been screened by the screening section by setting a clamping device on the conveying device. During the conveying process, the movable plate is pushed by the thrust elastic element to hit the angelica or soil on the lifting plate, which can break the soil or crush the soil attached to the angelica, thereby further cleaning the soil and reducing the soil content in the harvested angelica.

[0025] (2) The inclined surface of the wedge guides the movable plate, so that when the movable plate in the limiting groove passes the inclined surface of the wedge, the movable plate is lifted and gradually leaves the limiting groove. Then, under the push of the thrust elastic element, it moves towards the lifting plate in front, which can impact and squeeze the angelica or soil clods lifted on the lifting plate, making it easier to clean the soil clods.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0035] Example 1

[0036] This embodiment provides an Angelica dahurica harvester, such as Figures 1-5 As shown, the device includes a frame 1, a digging section 2 and a screening section 3 mounted on the frame 1, and a transmission section 4. The transmission section 4 includes a conveying device 5 located above the screening section 3 and a clamping device mounted on the conveying device 5. The clamping device includes several lifting plates 601 and movable plates 602 mounted on the conveying device 5. The lifting plate 601 includes a lifting surface facing the conveying direction of the conveying device 5 and a connecting surface away from the conveying direction of the conveying device 5. A thrust elastic element 603 is mounted on the connecting surface, and the movable plate 602 is mounted on the thrust elastic element 603. Fasteners for fixing are mounted on the movable plate 602.

[0037] The screening section 3 includes a vibrating filter screen connected to the excavation section 2 and a filter tank for temporary storage of Angelica dahurica connected to the vibrating filter screen. The lower end of the conveying device 5 is installed in the filter tank to deliver the Angelica dahurica from the filter tank. The conveying device 5 preferably adopts a chain conveyor or belt conveyor and is provided in two sets. The clamping device is mounted on the two sets of conveying devices 5. There is a through channel between the lifting plate 601 and the movable plate 602, that is, the Angelica dahurica or soil clods on the conveying device 5 can fall into the lower part of the conveying device 5 through the gap between the lifting plate 601 and the movable plate 602. The length of the lifting plate 601 and the movable plate 602 are both greater than the length of the Angelica dahurica and the width is both greater than the width of the Angelica dahurica. The thrust elastic element 603 is preferably a thrust spring, and preferably two or more are provided, evenly distributed along the long side of the lifting plate 601, and all the thrust elastic elements 603 on the same lifting plate 601 are mirror symmetrical.

[0038] In a more preferred embodiment, the fastener includes limiting grooves 604 fixedly installed on both sides of the lifting plate 601, the limiting grooves 604 matching the lower end of the movable plate 602. The limiting grooves 604 and the thrust elastic element 603 are installed on the same plane.

[0039] In a more preferred embodiment, the outer wall of the limiting groove 604 on the side away from the supporting plate 601 is provided as a slope 605. The slope 605 is inclined from the groove opening side of the limiting groove 604 towards the bottom side of the limiting groove 604.

[0040] In a more preferred embodiment, a wedge 7 is provided below the moving path of the clamping device to allow the movable plate 602 to disengage from the limiting groove 604, and a notch 606 is provided at the lower end of the lifting plate for the wedge to pass through.

[0041] The highest point of the wedge 7 is located above the limiting groove 604, which facilitates the ejection of the movable plate 602 from the limiting groove 604. The size of the notch 606 is larger than the size of the wedge 7, which facilitates the passage of the wedge 7.

[0042] In a more preferred embodiment, the moving path of the clamping device includes an upper clamping section and a lower reset section, and the wedge 7 is mounted on the clamping section; the clamping section extends from the wedge 7 to the lower side of the screening section 3 where a filter screen is provided.

[0043] In this solution, since the clamping device uses a conveyor belt, conveyor chain, etc., it includes an upper part for transporting Angelica dahurica and a lower rotating part. Therefore, the upper part is defined as the clamping section and the lower part is defined as the reset section. The wedge 7 is the component that activates the clamping device, so it is installed on the clamping section. The clamping device in the part of the clamping section before the wedge 7 is not activated and cannot clamp the Angelica dahurica. A filter screen needs to be set up to support it.

[0044] In a more preferred embodiment, the positions of the lifting plate 601 and the movable plate 602 on the clamping section and the reset section correspond to each other. That is, the gap between the lifting plate 601 and the movable plate 602 on the clamping section is below the gap between the lifting plate 601 and the movable plate 602 on the reset section, which facilitates the passage of angelica or soil clods.

[0045] In a more preferred embodiment, a traction motor 8 is mounted on the lifting plate 601, and the traction end of the traction motor 8 is connected to the movable plate 602.

[0046] Example 2

[0047] Based on Embodiment 1, a guide rod 607 is provided between adjacent lifting plates 601, and a guide groove 608 is provided on the movable plate 602, through which the guide rod 607 passes.

[0048] In a more preferred embodiment, the width of the guide groove 608 is equal to the diameter of the guide rod 607.

[0049] In a more preferred embodiment, the length of the guide groove 608 is greater than the diameter of the guide rod 607.
