Description

Technical Field

[0001] The utility model relates to a harvesting device, in particular to a harvesting device for Mongolian medicine Gentiana dahurica Fisch. flowers, belonging to the technical field of medicine harvesting devices. Background Art

[0002] Gentiana dahurica Fisch. flowers, with the Mongolian medicine name Huhe Zhuligen-Qimuge, are the dried flowers of Gentiana dahurica Fisch. of the genus Gentiana in the family Gentianaceae. At present, when harvesting Gentiana dahurica Fisch. flowers, it is usually manually collected, which is time-consuming and laborious, and a lot of impurities will be mixed in.

[0003] In the prior art, some special harvesting devices have also been designed for the harvesting of plant flowers. For example, a sugar beet picking and harvesting transporter disclosed in the publication number CN115413470A is also a device that uses the principle of vacuum adsorption for harvesting. It is provided with a vacuum harvesting mechanism, the vacuum harvesting mechanism is fixed on the collection box, and the suction port of the vacuum harvesting mechanism is located at the rear side of the vehicle body. The discharge port of the vacuum harvesting mechanism is communicated with the separation chamber. This sugar beet picking and harvesting transporter can separately carry out separation and harvesting operations on sugar beet roots and leaves, and there is no need to remove the leaves from the harvested sugar beet roots later. However, this device is a large driving device, that is, it can be applied to large-area harvesting operations. For the planting environment of Gentiana dahurica Fisch. flowers, Gentiana dahurica Fisch. flowers are often distributed and planted in areas such as mountain slopes. The existing harvesting devices are not convenient for direct operation in these areas. Moreover, although the existing devices can carry out separation operations after collection, they cannot separate and clean the particulate impurities, dry grass or dry leaves and other impurities entrained during the harvesting process, resulting in an unsatisfactory actual separation effect. Secondly, a safflower dry flower picking machine disclosed in the publication number CN205727101U, although it is aimed at the harvesting of dry flowers, only has a harvesting function and cannot further process the impurities entrained during the harvesting process. Moreover, when collecting the harvested dry flowers, there are also no corresponding anti-breaking measures, which greatly affects the work efficiency and harvesting quality.

Furthermore, the coarse-grained sundries entrained in the collected Gentiana dahurica Fisch. flowers can fall by hitting the inner wall of the lower cone under the action of centrifugal force. When the conveying air flow carries the Gentiana dahurica Fisch. flowers into the upper cone, since the inclination angle of the conical surface of the lower cone is greater than that of the conical surface of the upper cone, that is, the lower cone with a large cone angle can accelerate the radial movement of coarse particles, and the upper cone with a small cone angle can extend the axial residence time of the Gentiana dahurica Fisch. flowers in the upper cone, so as to facilitate the falling of the fine dust entrained in the Gentiana dahurica Fisch. flowers, that is, the separation of the particle sundries entrained in the vacuum adsorption collection process can be realized;

[0019] 3. The electrostatic adsorption separation component provided by the present utility model includes a separation housing and an electrostatic adsorption plate. Since during the vacuum adsorption collection of Gentiana dahurica Fisch. flowers, some sundries such as dry hay or dry leaves will also be entrained and adsorbed. And because the moisture content of sundries such as dry hay or dry leaves is extremely low, they are not only light in weight, but also obtain static charges through friction with the inner wall of the cone during the separation of particle sundries in and out of the double-cone centrifugal separation component. Then, after entering the separation housing, the dry hay or dry leaves with static charges are adsorbed by the electrostatic adsorption plate. However, since the Gentiana dahurica Fisch. flowers are heavier than sundries such as dry hay, the Gentiana dahurica Fisch. flowers cannot be adsorbed by the electrostatic adsorption plate.

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Embodiment 1

[0034] As Figure 1 、 Figure 3 、 Figure 6 and Figure 8As shown in the figure, a harvesting device for Mongolian medicine gentian flower includes a harvesting box 1. A vacuum conveyor 2 is arranged on the outer side of the harvesting box 1. A separation component and a harvested product collection cylinder 8 are arranged inside the harvesting box 1. The vacuum conveyor 2 is communicated with the input end of the separation component. The harvested product collection cylinder 8 is arranged directly below the output end of the separation component. By using the method of vacuum adsorption to collect gentian flower, the collection efficiency can be greatly improved. And during the harvesting process, there is no need for manual contact with the gentian flower, which greatly reduces the damage to the gentian flower during the collection process. And after collection, the separation component can separate the sundries entrained in the vacuum adsorption collection process. The gentian flower after impurity removal can be stored in the harvested product collection cylinder 8, which greatly improves the harvesting quality of the gentian flower;

[0035] The separation component includes a double-cone centrifugal separation component 3 and an electrostatic adsorption separation component 6. The discharge end of the double-cone centrifugal separation component 3 is communicated with the feed end of the electrostatic adsorption separation component 6. The double-cone centrifugal separation component 3 includes an upper cone 32 and a lower cone 31 which are butt-jointed together from bottom to top. The taper angle of the conical surface of the lower cone 31 is greater than that of the conical surface of the upper cone 32. The vacuum conveyor 2 is communicated with the bottom conical surface of the lower cone 31, and the material conveyed by the vacuum conveyor 2 is conveyed into the lower cone 31 along the tangential direction of the inner wall of the lower cone 31. When the harvested gentian flower is conveyed into the lower cone 31, since the gentian flower is conveyed along the tangential direction of the inner wall of the lower cone 31, the gentian flower can rise spirally along the inner wall of the lower cone 31 under the action of the conveying air flow. Thus, the coarse-grained sundries entrained in the collected gentian flower can fall by hitting the inner wall of the lower cone 31 under the action of centrifugal force. When the conveying air flow carries the gentian flower into the upper cone 32, since the taper angle of the conical surface of the lower cone 31 is greater than that of the conical surface of the upper cone 32, that is, the lower cone 31 with a large cone angle can accelerate the radial movement of the coarse particles, and the upper cone 32 with a small cone angle can extend the axial residence time of the gentian flower in the upper cone 32 to facilitate the falling of the fine dust entrained in the gentian flower. That is, the separation of the particulate sundries entrained in the vacuum adsorption collection process can be realized;

[0036] The electrostatic adsorption separation component 6 includes a separation housing 61 and an electrostatic adsorption plate 62. The electrostatic adsorption plate 62 is rotatably connected inside the separation housing 61. The bottom end of the separation housing 61 is communicated with the harvested product collection cylinder 8. The material entering the separation housing 61 is located below the electrostatic adsorption plate 62. A hay and sundry scraping component 9 is arranged on the lower plate surface of the electrostatic adsorption plate 62. During the vacuum adsorption and collection process of Gentiana dahurica Fisch. flowers, some sundries such as hay or dry leaves will also be carried and adsorbed. Since the moisture content of sundries such as hay or dry leaves is extremely low, they are not only light in weight, but also obtain static charges through friction with the inner wall of the cone during the separation of particle sundries in and out of the double-cone centrifugal separation component 3. Then, after entering the separation housing 61, the hay or dry leaves with static charges are adsorbed by the electrostatic adsorption plate 62. However, since the weight of Gentiana dahurica Fisch. flowers is larger than that of sundries such as hay, Gentiana dahurica Fisch. flowers cannot be adsorbed by the electrostatic adsorption plate 62. Therefore, the Gentiana dahurica Fisch. flowers after electrostatic separation can fall into the harvested product collection cylinder 8, that is, the separation of sundries such as hay or dry leaves carried during the vacuum adsorption collection process can be realized, and the sundries such as hay or dry leaves adsorbed on the lower plate surface of the electrostatic adsorption plate 62 can be cleaned and scraped off by the hay and sundry scraping component 9 to ensure that the electrostatic adsorption plate 62 can maintain a good adsorption and impurity removal effect during the long-term harvesting process.

[0037] Embodiment 2

[0038] Improved on the basis of Embodiment 1:

[0039] As Figures 1 to 5 shown, a box cover 11 is movably connected to the opening side of the box body of the harvesting box 1. A partition 12 is fixedly connected inside the box of the harvesting box 1. A storage battery 17 and an air pump 24 are also fixedly connected to the bottom of the box body of the harvesting box 1. The installation positions of the storage battery 17 and the air pump 24 are both below the partition 12. The storage battery 17 is electrically connected to each electrical component of the harvesting device. By opening and closing the set box cover 11, it is convenient to repair each component inside the harvesting box 1, and it is also convenient to take out the collected particle sundries and the harvested Gentiana dahurica Fisch. flowers. The set partition 12 can divide the harvesting box 1 into upper and lower cavities, so that the separation component and the harvested product collection cylinder 8 can be arranged above the partition 12, and the storage battery 17 and the air pump 24 are arranged below the partition 12, playing a role of separating and setting to avoid mutual influence. The set storage battery 17 can supply power to each electrical component to ensure that the harvesting device can operate outdoors for a long time. It should be noted that moving driving devices such as rollers can be further installed at the bottom of the box of the harvesting box 1, and a handle can be further installed at the upper end of the harvesting box 1 to facilitate carrying and moving the harvesting device during actual use.

[0040] Further, the air outlet end of the air pump 24 is connected to a telescopic air delivery pipe 23. The other end of the telescopic air delivery pipe 23 is connected to the vacuum conveyor 2. The output end of the vacuum conveyor 2 is connected to a telescopic suction pipe 21. A spiral conveyor pipe 22 is vertically connected inside the harvesting box 1. The upper end of the spiral conveyor pipe 22 is connected to the telescopic suction pipe 21. The bottom end of the spiral conveyor pipe 22 is connected to the upper cone 32. The air flow provided by the air pump 24 can be conveyed to the vacuum conveyor 2 through the telescopic air delivery pipe 23, so that the vacuum conveyor 2 can perform vacuum adsorption on the Gentiana dahurica Fisch. flowers to be collected, suck the Gentiana dahurica Fisch. flowers into the telescopic suction pipe 21, and further convey the Gentiana dahurica Fisch. flowers to the double-cone centrifugal separation assembly 3 through the spiral conveyor pipe 22. Moreover, the telescopic suction pipe 21 and the telescopic air delivery pipe 23 are provided with telescopic tube bodies, so as to facilitate the collection of Gentiana dahurica Fisch. flowers at different positions. It should be noted that the vacuum conveyor 2 can adopt the SUNAIR pneumatic conveyor of San'ai.

[0041] Further, sleeve rings 25 are fixedly sleeved on the tube bodies of the telescopic suction pipe 21 and the telescopic air delivery pipe 23. Spiral diversion grooves 26 are formed on the inner wall of the spiral conveyor pipe 22. The telescopic suction pipe 21 and the telescopic air delivery pipe 23 can be bundled together through the action of the sleeve rings 25, enabling the two pipes to be telescoped simultaneously. When the Gentiana dahurica Fisch. flowers enter the spiral conveyor pipe 22, the spiral diversion grooves 26 can provide a spiral guiding effect on the air flow in the pipe to ensure that the Gentiana dahurica Fisch. flowers can smoothly enter the double-cone centrifugal separation assembly 3.

[0042] Further, a conical fixing through groove 13 is formed on the plate body of the partition plate 12. The bottom end of the double-cone centrifugal separation assembly 3 is fixedly clamped in the conical fixing through groove 13. The bottom of the harvesting box 1 is fixedly connected with a first limit base 14. The connection position of the first limit base 14 is located directly below the conical fixing through groove 13, and a particle and debris collection cylinder 5 is movably arranged in the first limit base 14. The upper plate surface of the partition plate 12 is fixedly connected with a second limit base 15. The connection position of the second limit base 15 is located directly below the electrostatic adsorption separation assembly 6, and a harvested product collection cylinder 8 is movably arranged in the second limit base 15. The first limit base 14 and the second limit base 15 can respectively fixedly arrange the particle and debris collection cylinder 5 and the harvested product collection cylinder 8, so that when the harvesting device is moved, the displacement of the collection cylinders will not be caused. Moreover, the conical fixing through groove 13 can fix the installation position of the double-cone centrifugal separation assembly 3 to ensure that the double-cone centrifugal separation assembly 3 can stably perform centrifugal separation on the particle debris entrained in the Gentiana dahurica Fisch. flowers.

[0043] As Figure 2 、 Figure 3 、 Figures 6 to 11As shown in the figure, a collecting hopper 34 is connected to the bottom of the lower cone 31 of the double-cone centrifugal separation assembly 3. The outlet end of the collecting hopper 34 is connected to a solenoid valve 35. A flow guide plate 33 is fixedly connected to the inner wall of the lower cone 31. The flow guide plate 33 is arranged in an upward-inclined shape along the inner wall of the lower cone 31, and the plate body of the flow guide plate 33 is in a downward-inclined shape. The provided collecting hopper 34 facilitates the collection of centrifugally separated particulate impurities. After the harvesting operation is completed, the solenoid valve 35 is opened to drop the collected particulate impurities into the particulate impurity collection cylinder 5, facilitating the cleaning of the particulate impurities. At the same time, since the solenoid valve 35 is provided to keep the collecting hopper 34 closed during the harvesting operation, the airflow entering the double-cone centrifugal separation assembly 3 can only flow upward, that is, it can drive the Gentiana dahurica Fisch. flowers to be conveyed upward from the bottom end of the double-cone centrifugal separation assembly 3.

[0044] Furthermore, a conveying conduit 4 is connected between the separation housing 61 of the electrostatic adsorption separation assembly 6 and the top discharge port of the upper cone 32. A rotary motor 63 and an electrostatic generator 64 are fixedly connected to the inner wall of the top of the separation housing 61. The rotating shaft of the rotary motor 63 is fixedly connected coaxially with an electrostatic adsorption plate 62. The connection position of the electrostatic generator 64 is located on one side of the rotary motor 63, and the electrode end of the electrostatic generator 64 is placed on the upper plate surface of the electrostatic adsorption plate 62, so as to convey the Gentiana dahurica Fisch. flowers after particulate impurity separation to the inside of the separation housing 61 through the conveying conduit 4. At the same time, the electrostatic generator 64 makes the electrostatic adsorption plate 62 carry static charges to realize electrostatic adsorption of impurities such as hay or dry leaves entrained by the Gentiana dahurica Fisch. flowers. And during the adsorption process of the electrostatic adsorption plate 62 on impurities such as hay or dry leaves, the rotary motor 63 drives the electrostatic adsorption plate 62 to rotate, so that the hay impurity scraping assembly 9 can scrape off the adsorbed hay or dry leaves and other impurities. It should be noted that the electrostatic adsorption plate 62 can be made of an aluminum-based copper-clad laminate, and the inner wall of the separation housing 61 is coated with an insulating coating.

[0045] Furthermore, a guide cloth bag 7 is connected to the bottom opening of the separation housing 61 of the electrostatic adsorption separation assembly 6. The lower end of the guide cloth bag 7 is movably sleeved inside the harvested product collection cylinder 8. The harvested product collection cylinder 8 includes a cylinder frame 81, an outer peripheral cover net 82, and a bottom net 83. The outer peripheral cover net 82 is fixedly connected to the outer periphery of the cylinder frame 81, and the bottom net 83 is fixedly connected to the bottom end of the cylinder frame 81. The provided guide cloth bag 7 can form a sealed channel between the harvested product collection cylinder 8 and the bottom opening of the separation housing 61, thereby preventing the Gentiana dahurica Fisch. flowers from scattering outside the harvested product collection cylinder 8 during the downward dropping and collection process. And the outer periphery and bottom of the provided harvested product collection cylinder 8 are both provided with a net structure, which can make the dropped Gentiana dahurica Fisch. flowers land softly inside the harvested product collection cylinder 8, playing a protective role in the collection process of the Gentiana dahurica Fisch. flowers.

[0046] Further, a scraping component support rod 16 is connected below the hay and sundry scraping component 9, and the other end of the scraping component support rod 16 is supported and connected to the inner wall of one side of the harvesting box 1. The hay and sundry scraping component 9 includes an aggregate trough 91, a discharge pipe 92 and a scraping plate 93. The scraping plate 93 is connected in an inwardly inclined manner at the edge of the long side groove of one side of the aggregate trough 91. The bottom of the aggregate trough 91 is inclined. The length of the trough body of the aggregate trough 91 is equal to the radius of the plate body of the electrostatic adsorption plate 62. The discharge pipe 92 is communicated with one side of the inclined bottom end of the aggregate trough 91, and the pipe body of the discharge pipe 92 penetrates through the inner wall of one side of the harvesting box 1. The provided scraping component support rod 16 can play a good role in stable support for the hay and sundry scraping component 9. And when the electrostatic adsorption plate 62 rotates, the scraping plate 93 can scrape the plate body part with the radius length of the electrostatic adsorption plate 62 to ensure that the hay, dry leaves and other sundries adsorbed by the electrostatic adsorption plate 62 can be completely scraped off. The scraped sundries can fall into the aggregate trough 91 and can be discharged through the discharge pipe 92.

[0047] Working principle: The air flow provided by the air pump 24 is transported to the vacuum conveyor 2 through the telescopic air delivery pipe 23, so that the vacuum conveyor 2 is aligned with the Gentiana dahurica Fisch. flowers to be collected for vacuum adsorption, sucking the Gentiana dahurica Fisch. flowers into the telescopic suction pipe 21, and further transporting the Gentiana dahurica Fisch. flowers to the double-cone centrifugal separation assembly 3 through the spiral delivery pipe 22. When the collected Gentiana dahurica Fisch. flowers are transported into the lower cone 31, since the Gentiana dahurica Fisch. flowers are transported along the tangential direction of the inner wall of the lower cone 31, the Gentiana dahurica Fisch. flowers can spiral upward along the inner wall of the lower cone 31 under the action of the transported air flow. Furthermore, the coarse-grained sundries entrained in the collected Gentiana dahurica Fisch. flowers can fall by hitting the inner wall of the lower cone 31 under the action of centrifugal force. When the transported air flow carries the Gentiana dahurica Fisch. flowers into the upper cone 32, since the taper angle of the lower cone 31 is greater than that of the upper cone 32, that is, the large cone angle of the lower cone 31 can accelerate the radial movement of the coarse-grained particles, and the small cone angle of the upper cone 32 can extend the axial residence time of the Gentiana dahurica Fisch. flowers in the upper cone 32 to facilitate the falling of the fine dust entrained in the Gentiana dahurica Fisch. flowers. That is, the separation of the particle sundries entrained in the vacuum adsorption collection process can be realized. While the particle sundries are separated in and out of the double-cone centrifugal separation assembly 3, sundries such as hay or dry leaves obtain static charges by rubbing against the inner wall of the cone. Furthermore, after entering the separation housing 61, the hay or dry leaves with static charges are adsorbed by the static adsorption plate 62. Since the weight of the Gentiana dahurica Fisch. flowers is larger than that of sundries such as hay, the Gentiana dahurica Fisch. flowers cannot be adsorbed by the static adsorption plate 62. Therefore, the Gentiana dahurica Fisch. flowers after electrostatic separation can fall into the harvested product collection cylinder 8, that is, the separation of sundries such as hay or dry leaves entrained in the vacuum adsorption collection process can be realized, and the sundries such as hay or dry leaves adsorbed on the lower plate surface of the static adsorption plate 62 can be cleaned and scraped off by the hay sundries scraping assembly 9 to ensure that the static adsorption plate 62 can maintain a good adsorption and impurity removal effect during the long-term harvesting process. The Gentiana dahurica Fisch. flowers after impurity removal can be stored in the harvested product collection cylinder 8, greatly improving the harvesting quality of the Gentiana dahurica Fisch. flowers.
