Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a harvesting device for Fritillaria thunbergii flowers. Background Technology

[0002] Fritillaria thunbergii, the dried bulb of the plant *Fritillaria thunbergii*, belongs to the Liliaceae family. It possesses properties of clearing heat, resolving phlegm, relieving cough, detoxifying, dispersing nodules, and reducing swelling. It is used for wind-heat cough, phlegm-fire cough, lung abscess, and carbuncles. During its growth, *Fritillaria thunbergii* requires flower removal to promote the enlargement and growth of the underground bulb, thereby increasing yield. Specifically, *Fritillaria thunbergii* requires a large amount of nutrients to support its growth, and flowering consumes a significant amount of these nutrients. If the flowers are not removed in time, nutrients will be used for flowering rather than for the development of the underground bulb. Therefore, after flowering, farmers promptly remove the flowers to control the growth of the above-ground parts, ensuring that nutrients are concentrated on the underground bulb, thus promoting its enlargement and growth.

[0003] The flowers of Fritillaria thunbergii are typically removed manually. These removed flowers can be used for drug purification, making them a valuable medicinal raw material. However, manual removal is not only inefficient but also time-consuming and labor-intensive. Some farmers use electric rotary blades to remove the flowers, but this method easily damages the plant's stems and leaves, and the flowers are easily broken, making it difficult to ensure their integrity. Furthermore, the broken flowers cannot be collected and utilized, resulting in waste. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a harvesting device that will not damage the stems and leaves of the plant and can efficiently and completely harvest the flowers of Fritillaria thunbergii.

[0005] The technical solution of this utility model is to provide a harvesting device for Fritillaria thunbergii flowers with the following structure: including a frame and a cutting mechanism and a collecting mechanism connected to both ends of the frame;

[0006] The cutting mechanism includes a collecting cover, a cutting support, a driving unit, and a cutting blade. The collecting cover is funnel-shaped, wider at the top and narrower at the bottom, with a first through hole at its lower end. A conveying channel extends along the length of the collecting cover and passes through both ends of the collecting cover. The collecting cover is connected to one end of the collecting cover, and the first through hole communicates with the conveying channel. The cutting support is connected to the upper opening of the collecting cover. The driving unit is fixedly connected to the cutting support, and its output end is connected to the cutting blade to drive the cutting blade to move horizontally and cut the Fritillaria thunbergii flowers that extend into the collecting cover.

[0007] The collection mechanism includes a housing, a collection net, and a fan disposed within the housing; the housing has a second through hole and a third through hole at its two ends, the housing is connected to the other end of the frame, and the second through hole is connected to the conveying channel; the collection net is disposed on the side near the second through hole, and its opening is connected to the second through hole; the fan is disposed on the side near the third through hole, and is used to draw air from the first through hole and discharge it from the third through hole.

[0008] After adopting the above structure, the Zhejiang fritillary flower harvesting device of this utility model has the following advantages compared with the prior art:

[0009] When picking the flowers of Fritillaria thunbergii, the flowers are placed inside a collection hood, and then cut horizontally with a cutting blade. Under the suction of a fan, the flowers will enter the conveying channel through the first through hole, and after passing through the second through hole, they will enter the collection net, thus completing the picking and collection of the flowers. This device has high collection efficiency and will not damage the stems and leaves of the plant. The picked flowers are highly intact and easy to recycle.

[0010] Preferably, the cutting bracket is provided with two parallel guide rails extending along its width, and the two ends of the cutting blade are connected to blade holders, which are slidably connected to the corresponding guide rails. The cooperation between the blade holders and the guide rails ensures that the cutting blade moves stably along a preset trajectory, preventing deviation and cutting failure.

[0011] Preferably, there are two drive units symmetrically arranged at both ends of the cutting bracket; there are two cutting blades symmetrically arranged and slidably connected to the guide rail; the output ends of the two drive units are connected to the corresponding cutting blades to drive the two cutting blades to move towards or in opposite directions. This reduces the drive stroke of the drive units and completes the cutting more quickly.

[0012] Preferably, one side wall of the outer casing is provided with a compartment for removing or placing the collection net into the inner cavity of the outer casing, and the compartment is connected to a cover plate that can be opened. The collection net is made of iron mesh, and the opening faces the direction of the second through hole; the size of the compartment is matched with the size of the collection net, which facilitates the removal and placement of the collection net.

[0013] Preferably, the inner diameter of the conveying channel gradually increases from one end near the first through hole to the other. This allows for greater suction at the first through hole and prevents the flowers from getting stuck in the conveying channel.

[0014] Preferably, the frame is equipped with a handle, which is positioned on the side closest to the collection mechanism. Since the collection mechanism is relatively heavy, the handle is placed closer to it to ensure the user can maintain balance when holding it. Control buttons can also be installed on the handle to control the start and stop of the drive unit and the fan. Attached Figure Description

[0023] like Figures 1-4 As shown, this utility model discloses a harvesting device for Fritillaria thunbergii flowers: including a frame 1 and a cutting mechanism 2 and a collecting mechanism 3 connected to both ends of the frame 1.

[0024] The frame 1 is provided with a conveying channel 11 that extends along its length and passes through both ends of it. The two ends of the conveying channel 11 are connected to the cutting mechanism 2 and the collecting mechanism 3, respectively.

[0025] The cutting mechanism 2 includes a collection cover 21, a cutting bracket 22, a drive unit 23, and a cutting blade 24. The collection cover 21 is funnel-shaped, wider at the top and narrower at the bottom, and has a first through hole 211 at its lower end for the flowers to pass through. The collection cover 21 is connected to one end of the frame 1, and the first through hole 211 is connected to the conveying channel 11. The cutting bracket 22 is connected to the upper opening of the collection cover 21. The drive unit 23 is fixedly connected to the cutting bracket 22, and the output end of the drive unit 23 is connected to the cutting blade 24 to drive the cutting blade 24 to move horizontally and cut the Fritillaria thunbergii flowers that have entered the collection cover 21.

[0026] The cutting bracket 22 is provided with two parallel guide rails 221 extending along its width. The two ends of the cutting blade 24 are connected to blade holders 241, which are slidably connected to the corresponding guide rails 221. Through the cooperation between the blade holders 241 and the guide rails 221, the cutting blade 24 can be ensured to move stably along the preset trajectory, avoiding deviation that could cause cutting failure.

[0027] There are two drive units 23, symmetrically arranged at both ends of the cutting bracket 22; there are also two cutting blades 24, symmetrically arranged and slidably connected to the guide rail 221; the output ends of the two drive units 23 are connected to the corresponding cutting blades 24, which are used to drive the two cutting blades 24 to move towards or away from each other, so that the driving stroke of the drive unit 23 can be halved, and the cutting can be completed more quickly.

[0028] The collection mechanism 3 includes a housing 31 and a collection net 32 ​​and a fan 33 disposed inside the housing 31. The housing 31 has a second through hole 311 and a third through hole 312 at its two ends, and the housing 31 is connected to the other end of the frame 1. The second through hole 311 is connected to the conveying channel 11. The collection net 32 ​​is made of iron mesh and is disposed on the side near the second through hole 311, with its opening facing the direction of the second through hole 311 and connected to the second through hole 311. The fan 33 is disposed on the side near the third through hole 312 and is used to draw air from the first through hole 211 and discharge it from the third through hole 312.

[0029] A compartment (not shown in the figure) is provided on one side wall of the outer casing 31 for taking out or putting in the collection net 32 ​​into the inner cavity of the outer casing 31. The size of the compartment is matched with the size of the collection net 32 ​​to facilitate the taking out and putting in the collection net 32. A cover plate is also rotatably connected to the compartment for opening or closing the compartment.

[0030] The inner diameter of the conveying channel 11 gradually increases from one end near the first through hole 211 to the other end, which can make the suction at the first through hole 211 stronger and also prevent the flowers from accumulating and getting stuck in the conveying channel 11.

[0031] A handle 12 is attached to the frame 1. Since the collection mechanism 3 is relatively heavy, in order to balance the front and back gravity when the user holds it, the handle 12 can be placed on the side closer to the collection mechanism 3.

[0032] A control button can also be installed on the handle 12, which is electrically connected to the control drive unit 23 and the fan 33 via a controller, thereby controlling the start and stop of the drive unit 23 and the fan 33. The drive unit 23 is a linear motor, powered by a battery, which can be integrated into the housing 31 or an external battery mounted on a shoulder strap.

[0033] In this invention, when removing the flowers of Fritillaria thunbergii, the flowers are placed inside the collection cover 21, and then the flowers are horizontally cut by the cutting blade 24. Under the suction of the fan 33, the flowers will enter the conveying channel 11 through the first through hole 211, and after passing through the second through hole 311, they will enter the collection net 32, thus completing the picking and collection of the flowers. This device has high collection efficiency and will not damage the stems and leaves of the plant. The picked flowers are highly intact and easy to recycle.
