Description

Technical Field

[0001] This invention relates to the field of Dendrobium harvesting technology, specifically to a harvesting device for Dendrobium production and its working method. Background Technology

[0002] Dendrobium, also known as Immortal Orchid, Immortal Grass, Resurrection Grass, Purple Fairy Plant, Hanging Orchid, Forest Orchid, Forbidden Life, etc., is a medicinal plant. It is sweet, bland and slightly salty in taste, cold in nature, and enters the stomach, kidney and lung meridians. It benefits the stomach and promotes the production of body fluids, nourishes yin and clears heat. It is used for yin deficiency and fluid depletion, dry mouth and thirst, poor appetite and dry retching, post-illness weakness and fever, and blurred vision. Purple-skinned Dendrobium is a herbaceous plant of the Dendrobium genus in the Orchidaceae family. Dendrobium dentata is the representative. The stem of purple-skinned Dendrobium is 50-70cm tall, fleshy, slender and cylindrical, with papery leaves and powdery seeds. Dendrobium often grows with moss and is mostly epiphytic on tree trunks or rock walls in deep mountains and old forests.

[0003] Currently, most methods of harvesting Dendrobium involve manual harvesting using scissors. If Dendrobium grows on high tree trunks or rock walls, climbing tools are needed. However, when workers use climbing tools to harvest Dendrobium, it is inconvenient to move the plant, resulting in very low harvesting efficiency.

[0004] Therefore, there is a need for a harvesting device and its working method for Dendrobium production to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problem, namely the low harvesting efficiency of existing Dendrobium harvesting methods, this invention provides a harvesting device for Dendrobium production and its operating method.

[0006] A harvesting device for Dendrobium officinale production includes a sleeve and a sleeve rod. The sleeve rod is slidably installed inside the sleeve. A connecting frame is fixedly installed at one end of the sleeve rod, and a support ring is fixedly installed at one end of the connecting frame. A lower sleeve ring is rotatably installed at the bottom of the support ring, and an upper sleeve ring is rotatably installed at the top of the support ring. A sorting inclined plate is installed through the lower sleeve ring and is drivenly connected to the lower surface of the support ring. A clamping arc plate is installed through the support ring and is drivenly connected to the lower surface of the upper sleeve ring. An alternating drive mechanism is provided inside the connecting frame and is drivenly connected to the lower and upper sleeve rings. A blade is installed on the lower sleeve ring. By placing the support ring at one end of the sleeve rod... The sleeve rod is slidably installed inside the sleeve. When harvesting Dendrobium, if it is inconvenient for the operator to move and the operator is far away from the Dendrobium, the sleeve rod can slide, allowing the operator to harvest Dendrobium from a distance without moving, effectively improving harvesting efficiency. By setting a sorting inclined plate on the lower sleeve ring and driving the sorting inclined plate to the support ring, the sorting inclined plate can be translated while the lower sleeve ring rotates, which can sort the messy Dendrobium and make it easier to cut and collect. By installing a clamping arc plate on the support ring and driving the clamping arc plate to the upper sleeve ring, the clamping arc plate can be translated while the upper sleeve ring rotates, which can clamp the sorted Dendrobium and make it easier to collect, further improving harvesting efficiency.

[0007] The above-mentioned harvesting equipment for Dendrobium production has a first end of the sleeve that is open-ended. A threaded hole is formed inside the sleeve rod, and a drive screw is threaded into the threaded hole. One end of the drive screw passes through the second end of the sleeve and extends to the outside of the sleeve. A limiting ring is coaxially fixedly installed on the outer surface of the drive screw. The limiting ring rotates within the wall of one end of the sleeve. One end of the sleeve rod extends to the outside of the sleeve and is fixedly connected to the connecting frame. When the drive screw is rotated, the threaded hole and the drive screw will undergo threaded movement. Since the cross-section of the sleeve rod is square and cannot rotate, the sleeve rod will translate under the drive of the drive screw, thus achieving an elongation effect.

[0008] The aforementioned harvesting equipment for Dendrobium production includes a support ring with a serrated groove on its lower surface, a lower sleeve ring with an inverted U-shaped cross-section, and a first serrated plate horizontally slidably mounted on the lower sleeve ring. The serrated teeth on the upper surface of the first serrated plate mesh with the serrated groove on the lower surface of the support ring. A sorting serrated plate is fixedly mounted at one end of the first serrated plate located inside the lower sleeve ring. When the lower sleeve ring rotates, the first serrated plate is driven by the serrated groove on the lower surface of the support ring, causing the sorting serrated plate to move horizontally. The inclined sorting serrated plate moves the disordered Dendrobium, thereby gathering the multiple necks of the Dendrobium and exposing the roots for easy cutting.

[0009] The above-mentioned harvesting equipment for Dendrobium production includes an upper collar with a convex cross-section on its lower surface and a second slidable toothed plate horizontally mounted on the support ring. The slids on the upper surface of the second slidable toothed plate mesh with the slids on the lower surface of the upper collar. A clamping arc plate is fixedly mounted on one end of the second slidable toothed plate located inside the support ring. A rubber sheet is provided between the two ends of the second slidable toothed plate. By providing a rubber sheet between the two ends of the clamping arc plate, the inner side of the clamping arc plate is made flat, which facilitates the clamping of Dendrobium. Furthermore, because the rubber sheet is soft, regardless of the size of the Dendrobium neck, the two rubber sheets can be brought together to clamp the Dendrobium without damaging it.

[0010] In the aforementioned harvesting equipment for Dendrobium production, the end of the connecting frame near the support ring is a transparent end. The alternating drive mechanism includes a drive motor, which is fixedly installed at the bottom of the connecting frame. The output shaft of the drive motor extends into the interior of the connecting frame and is coaxially fixedly mounted with a drive gear. A support rod is vertically fixedly installed inside the connecting frame, located between the drive gear and the support ring. A movable gear is slidably mounted on the support rod, meshing with the drive gear. A first spring is provided between the top of the movable gear and the top wall of the connecting frame.

[0011] The aforementioned harvesting equipment for Dendrobium production features toothed grooves on the outer surface of the lower ring near the top and the outer surface of the upper ring near the bottom. The movable gear alternately meshes with the toothed grooves on the outer surfaces of the lower and upper rings. By employing an alternating drive mechanism, in the initial state, under the elastic force of the first spring, the movable gear meshes with the toothed groove on the outer surface of the lower ring, driving the lower ring to rotate. When the movable gear is pulled up by an external force, it meshes with the toothed groove on the outer surface of the upper ring, driving the upper ring to rotate. This simplifies the internal mechanism and facilitates operation.

[0012] In the aforementioned harvesting equipment for Dendrobium production, a winding wheel is rotatably mounted on the top wall of the sleeve at the end away from the support ring. Part of the winding wheel extends to the top of the sleeve, and a pull rope is wound on the winding wheel. A first rope-passing hole is provided through the top wall of the connecting frame, and a second rope-passing hole is provided inside the top wall of the sleeve. One end of the pull rope passes through the second rope-passing hole and the first rope-passing hole in sequence and connects to the upper surface of the movable gear. By rotating the winding wheel, the movable gear can be lifted by pulling the rope.

[0013] The above-mentioned harvesting equipment for Dendrobium production includes a locking shaft coaxially fixed at one end of the winding wheel. The locking shaft has a locking hole on its outer surface, and an insertion hole is provided at the top of the sleeve. A locking rod is inserted into the insertion hole, with its bottom end extending into the locking hole on the outer surface of the locking shaft. A reset cavity is provided on the outer side of the insertion hole, and a spring seat is fixedly installed on the outer surface of the locking rod. The spring seat slides within the reset cavity, and a second spring is provided on the upper surface of the spring seat. When it is necessary to lift the movable gear, the locking rod is lifted, and then the winding wheel is rotated. After the movable gear is lifted, the locking rod is lowered. Under the pressure of the second spring, the locking rod fixes the locking shaft, thereby preventing the winding wheel from rotating.

[0014] The above-mentioned harvesting equipment for Dendrobium production includes an electric telescopic rod fixedly installed through the lower sleeve, and a blade fixedly installed at one end of the electric telescopic rod located inside the lower sleeve. The height of the blade is lower than the height of the sorting inclined plate. After the clamping arc plate clamps the Dendrobium after it has been sorted by the sorting inclined plate, the electric telescopic rod is controlled by the control device to make the blade cut the root of the Dendrobium.

[0015] A method for operating a harvesting device for Dendrobium production includes the following steps:

[0016] Step A: Length adjustment: Rotate the drive screw to extend the sleeve out of the sleeve;

[0017] Step B: Arranging Dendrobium: Place the Dendrobium inside the support ring, turn the drive motor, and the drive gear drives the lower ring to rotate through the movable gear. The first oblique tooth plate will be driven by the oblique tooth groove on the lower surface of the support ring, which will drive the arranging oblique plate to move inward while rotating, and tidy up the messy Dendrobium.

[0018] Step C: Clamping Dendrobium: Rotate the winding wheel and lift the movable gear by pulling the rope. The movable gear drives the upper collar. When the upper collar rotates, the oblique tooth groove on the lower surface will drive the second oblique tooth plate, causing the second oblique tooth plate to move the clamping arc plate inward to clamp the Dendrobium.

[0019] Step D: Cutting Dendrobium: Use the control button to extend the electric telescopic rod, which drives the blade to cut the root of the Dendrobium, thus completing the harvest.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. This invention, by setting a sorting inclined plate on the lower collar and driving the sorting inclined plate to the support ring, allows the sorting inclined plate to translate while rotating the lower collar, thus sorting the messy Dendrobium orchids and facilitating cutting and collection; by installing a clamping arc plate on the support ring and driving the clamping arc plate to the upper collar, the clamping arc plate can translate while rotating the upper collar, thereby clamping the sorted Dendrobium orchids and facilitating collection, further improving harvesting efficiency.

[0022] 2. In this invention, by setting a support ring at one end of the sleeve rod and sliding the sleeve rod inside the sleeve, if it is inconvenient for the operator to move the sleeve rod when harvesting Dendrobium orchids and the operator is far away from the Dendrobium orchids, the sleeve rod can be slid, so that the operator can harvest Dendrobium orchids at a distance without moving, which effectively improves the harvesting efficiency.

[0023] 3. In this invention, by setting a rubber sheet between the two ends of the clamping arc plate, the inner side of the clamping arc plate is made flat, which makes it easy to clamp the Dendrobium. Since the rubber sheet is soft, no matter how much or little the neck of the Dendrobium is, the two rubber sheets can be brought together to clamp the Dendrobium without damaging it.

[0024] 4. The present invention, by setting an alternating drive mechanism, in the initial state, under the elastic force of the first spring, the movable gear meshes with the tooth groove on the outer surface of the lower collar, driving the lower collar to rotate. When the movable gear is pulled up by an external force, the movable gear meshes with the tooth groove on the outer surface of the upper collar, driving the upper collar to rotate, thus simplifying the internal mechanism and facilitating operation.

[0036] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0037] like Figure 1-2 As shown in the figure, this invention discloses a harvesting device for Dendrobium production and its working method, including a sleeve 1 and a sleeve rod 2. The sleeve rod 2 is slidably installed inside the sleeve 1. A connecting frame 3 is fixedly installed at one end of the sleeve rod 2, and a support ring 4 is fixedly installed at one end of the connecting frame 3. A lower sleeve ring 5 is rotatably installed at the bottom of the support ring 4, and an upper sleeve ring 6 is rotatably installed at the top of the support ring 4. A sorting inclined plate 7 is installed through the lower sleeve ring 5 and is drivenly connected to the lower surface of the support ring 4. A clamping arc plate 8 is installed through the support ring 4 and is drivenly connected to the lower surface of the upper sleeve ring 6. An alternating drive mechanism is provided inside the connecting frame 3, and the alternating drive mechanism is drivenly connected to the lower sleeve ring 5 and the upper sleeve ring 6. A blade 9 is installed on the lower sleeve ring 5. By setting the support ring 4 at one end of the sleeve rod 2, The sleeve rod 2 is slidably installed inside the sleeve 1. When the operator is harvesting Dendrobium, if it is inconvenient to move the sleeve rod and the operator is far away from the Dendrobium, the sleeve rod 2 can be slid, allowing the operator to harvest Dendrobium from a distance without moving, effectively improving harvesting efficiency. By setting a sorting inclined plate 7 on the lower sleeve ring 5 and drivingly connecting the sorting inclined plate 7 to the support ring 4, the sorting inclined plate 7 can be translated while rotating the lower sleeve ring 5, which can sort the messy Dendrobium and make it easier to cut and collect. By installing a clamping arc plate 8 on the support ring 4 and drivingly connecting the clamping arc plate 8 to the upper sleeve ring 6, the clamping arc plate 8 can be translated while rotating the upper sleeve ring 6, which can clamp the sorted Dendrobium and make it easier to collect, further improving harvesting efficiency.

[0038] like Figure 3 As shown, the first end of the sleeve 1 is a through end, and the inside of the sleeve rod 2 is provided with a threaded hole 10. A drive screw 11 is installed inside the threaded hole 10. One end of the drive screw 11 passes through the second end of the sleeve 1 and extends to the outside of the sleeve 1. A limiting ring 12 is coaxially fixedly installed on the outer surface of the drive screw 11. The limiting ring 12 rotates inside the tube wall at one end of the sleeve 1. One end of the sleeve rod 2 extends to the outside of the sleeve 1 and is fixedly connected to the connecting frame 3. When the drive screw 11 is rotated, the threaded hole 10 will have a threaded movement with the drive screw 11. Since the cross-section of the sleeve rod 2 is square and cannot rotate, the sleeve rod 2 will translate under the drive of the drive screw 11, thereby achieving the effect of elongation.

[0039] like Figure 1-2 and Figure 6 As shown, the lower surface of the support ring 4 is provided with oblique tooth grooves, and the cross-section of the lower sleeve ring 5 is inverted convex shape. A first oblique tooth plate 13 is horizontally slidably installed on the lower sleeve ring 5. The oblique teeth on the upper surface of the first oblique tooth plate 13 are engaged with the oblique tooth grooves on the lower surface of the support ring 4. The sorting oblique plate 7 is fixedly installed at one end of the first oblique tooth plate 13 located inside the lower sleeve ring 5. When the lower sleeve ring 5 rotates, the first oblique tooth plate 13 is driven through the oblique tooth grooves on the lower surface of the support ring 4, which drives the sorting oblique plate 7 to move horizontally. The inclined sorting oblique plate 7 will move the messy dendrobium, thereby gathering the multiple necks of the dendrobium and exposing the roots for easy cutting.

[0040] like Figure 2 and Figure 8 As shown, the lower surface of the upper collar 6 is provided with oblique tooth grooves, and the cross-section of the upper collar 6 is convex. A second oblique tooth plate 14 is horizontally slidably installed on the support ring 4. The oblique teeth on the upper surface of the second oblique tooth plate 14 are engaged with the oblique tooth grooves on the lower surface of the upper collar 6. The clamping arc plate 8 is fixedly installed at one end of the second oblique tooth plate 14 located inside the support ring 4. A rubber sheet 15 is provided between the two ends of the second oblique tooth plate 14. By providing a rubber sheet 15 between the two ends of the clamping arc plate 8, the inner side of the clamping arc plate 8 is made to be flat, which facilitates the clamping of Dendrobium. Moreover, since the rubber sheet 15 is soft, no matter how much or little the neck of Dendrobium is, the two rubber sheets 15 can be brought together to clamp Dendrobium without damaging it.

[0041] like Figure 2As shown, the end of the connecting frame 3 near the support ring 4 is a through end. The alternating drive mechanism includes a drive motor 16, which is fixedly installed at the bottom of the connecting frame 3. The output shaft of the drive motor 16 extends into the interior of the connecting frame 3 and is coaxially fixedly installed with a drive gear 17. A support rod 18 is vertically fixedly installed inside the connecting frame 3. The support rod 18 is located between the drive gear 17 and the support ring 4. A movable gear 19 is slidably installed on the support rod 18. The movable gear 19 is meshed with the drive gear 17. A first spring 20 is provided between the top of the movable gear 19 and the top wall of the connecting frame 3.

[0042] like Figure 2 As shown, the outer surface of the lower collar 5 near the top and the outer surface of the upper collar 6 near the bottom are both provided with toothed grooves. The movable gear 19 alternately meshes with the toothed grooves on the outer surface of the lower collar 5 and the upper collar 6. By setting an alternating drive mechanism, in the initial state, under the elastic force of the first spring 20, the movable gear 19 meshes with the toothed groove on the outer surface of the lower collar 5, driving the lower collar 5 to rotate. When the movable gear 19 is pulled up by an external force, the movable gear 19 meshes with the toothed groove on the outer surface of the upper collar 6, driving the upper collar 6 to rotate. This simplifies the internal mechanism and facilitates operation.

[0043] like Figure 1 and Figure 4 As shown, a winding wheel 21 is rotatably mounted on the top wall of the sleeve 1 at the end away from the support ring 4. Part of the winding wheel 21 extends to the top of the sleeve 1. A pull rope 22 is wound on the winding wheel 21. A first rope hole 23 is opened through the top wall of the connecting frame 3. A second rope hole 24 is opened in the top wall of the sleeve 1. One end of the pull rope 22 passes through the second rope hole 24 and the first rope hole 23 in sequence and connects to the upper surface of the movable gear 19. By rotating the winding wheel 21, the movable gear 19 can be lifted by pulling the rope 22.

[0044] like Figure 4 As shown, a retaining rod 25 is coaxially fixed to one end of the winding wheel 21. A retaining hole is provided on the outer surface of the retaining rod 25. An insertion hole 26 is provided on the top of the sleeve 1. A retaining rod 27 is inserted into the insertion hole 26. The bottom end of the retaining rod 27 extends into the retaining hole on the outer surface of the retaining rod 25. A reset cavity 28 is provided on the outer side of the insertion hole 26. A spring seat 29 is fixedly installed on the outer surface of the retaining rod 27. The spring seat 29 slides in the reset cavity 28. A second spring 30 is provided on the upper surface of the spring seat 29. When it is necessary to lift the movable gear 19, the retaining rod 27 is lifted, and then the winding wheel 21 is rotated. After the movable gear 19 is lifted, the retaining rod 27 is lowered. Under the pressure of the second spring 30, the retaining rod 27 fixes the retaining rod 25, thereby preventing the winding wheel 21 from rotating.

[0045] like Figure 1-2 and Figure 9As shown, an electric telescopic rod 31 is fixedly installed through the lower collar 5, and a blade 9 is fixedly installed at one end of the electric telescopic rod 31 located inside the lower collar 5. The height of the blade 9 is lower than the height of the arranging inclined plate 7. After the clamping arc plate 8 clamps the Dendrobium after it has been arranged by the arranging inclined plate 7, the electric telescopic rod 31 is controlled by the control device to make the blade 9 cut the root of the Dendrobium.

[0046] A method for operating a harvesting device for Dendrobium production includes the following steps:

[0047] Step A: Length adjustment: Rotate the drive screw 11 to extend the sleeve 2 out of the sleeve 1;

[0048] Step B: Arranging Dendrobium: Place the Dendrobium inside the support ring 4, make the drive motor 16 rotate, and the drive gear 17 drives the lower ring 5 to rotate through the movable gear 19. The first oblique tooth plate 13 will be driven by the oblique tooth groove on the lower surface of the support ring 4, which will drive the arranging oblique plate 7 to move inward while rotating, and arranging the messy Dendrobium.

[0049] Step C: Clamping Dendrobium: Rotate the winding wheel 21 and lift the movable gear 19 by pulling the rope, so that the movable gear 19 drives the upper collar 6. When the upper collar 6 rotates, the oblique tooth groove on the lower surface will drive the second oblique tooth plate 14, so that the second oblique tooth plate 14 drives the clamping arc plate 8 to move inward to clamp the Dendrobium.

[0050] Step D: Cutting Dendrobium: Control the electric telescopic rod 31 to extend by controlling the button, which drives the blade 9 to cut the root of the Dendrobium, and the harvesting is completed.
