Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to an auxiliary device for non-destructive harvesting of Camellia chrysantha flowers. Background Technology

[0002] As a valuable ornamental, medicinal, and economic crop, the integrity of the flower's shape has a crucial impact on its value. Currently, the harvesting of golden camellia flowers mainly relies on manual labor. This method is not only inefficient and labor-intensive, but also difficult to precisely control the force applied during harvesting, easily leading to petal damage, deformation, or loss due to human error.

[0003] To improve harvesting efficiency, some mechanized harvesting equipment has emerged, such as those using robotic arm end effectors for grasping or cutting. However, these devices have revealed significant technical shortcomings when applied to high-value, highly fragile flowers like Camellia chrysantha.

[0004] On the one hand, existing mechanical positioning and harvesting mechanisms are mostly rigid structures. When the robotic arm drives it to approach the flower, the instantaneous impact force generated by positioning deviation or motion inertia can easily cause hard contact with the petals, resulting in scratches or damage to the petals. At the same time, when clamping and positioning the flower to assist in harvesting, rigid clamping components are difficult to adapt to different branch thicknesses, and can easily cause squeezing damage to the base of the flower or the branch due to excessive clamping force.

[0005] On the other hand, existing technologies lack sufficient consideration for the non-destructive aspects of flower collection and transportation after the picking process. After being separated, flowers are often collected by simple dropping or rigid conveyor belts. During this process, flowers are very prone to rolling, collision, stacking, and friction, which can cause wear and tear on the petal edges or damage to their shape, resulting in serious secondary damage.

[0006] In summary, existing harvesting techniques often fail to balance the flexible buffering during the positioning and clamping stage with the lossless transport during the post-harvest collection stage. There is a lack of a lossless solution that can cover the entire harvesting assistance process, resulting in cumulative damage to the flowers throughout the entire process from positioning to final storage, which seriously affects the quality and economic value of Camellia chrysantha.

[0007] Therefore, this utility model proposes an auxiliary device for non-destructive harvesting of Camellia chrysantha flowers to address the shortcomings of existing technologies. Utility Model Content

[0008] In view of the problems in the existing technology of non-destructive picking auxiliary devices for Camellia chrysantha flowers, such as petal damage caused by rigid contact and impact during picking and positioning, and secondary damage caused by collision and stacking during the collection and transportation process after picking, this utility model aims to provide a non-destructive picking auxiliary device for Camellia chrysantha flowers with an improved structure that can effectively solve the above problems.

[0009] This utility model provides an auxiliary device for non-destructive harvesting of Camellia chrysantha flowers, comprising: a fixing block, a positioning and screening component fixedly connected to the fixing block, and a collection component communicating with the internal cavity of the positioning and screening component.

[0010] The positioning and screening component, as a core innovative structure, includes a guide cover, a silicone buffer ring, and an annular petal positioning ring. The annular petal positioning ring includes circumferentially distributed arc-shaped silicone blocks, a slider fixedly connected to the arc-shaped silicone blocks, a groove for accommodating the sliding of the slider, a limiting block fixedly disposed on the inner wall of the groove, and a spring connecting the arc-shaped silicone blocks and the bottom of the groove.

[0011] Furthermore, the guide cover is fixedly installed on the bottom of the fixed block; the silicone buffer ring is located on the inner side of the guide cover and at the opening end of the guide cover; the annular petal positioning ring is located behind the silicone buffer ring; the groove is formed on the fixed block; the slider is slidably connected to the groove. Through the combination of the above structures, a complete flexible positioning and screening system is formed.

[0012] Preferably, the arc-shaped silicone blocks are evenly distributed along the circumference of the annular petal positioning ring. This arrangement makes the pressure exerted on the branch surface by the annular petal positioning ring more balanced when it performs adaptive clamping, thus avoiding local stress concentration.

[0013] Preferably, the collection assembly includes a vacuum pump, a hose, a folded tube, a guide head, and an outlet; the folded tube forms the inlet of the collection assembly and is connected to the positioning and screening assembly, and the other end of the folded tube is connected to the guide head through the hose; the guide head is provided with the outlet; the suction port of the vacuum pump is connected to the hose or the folded tube, and this combination forms a complete, negative pressure-driven, contactless collection path.

[0014] Preferably, in the above solution, the guide head has a smooth arc-shaped inner wall structure. This smooth inner wall can gently guide the flowers in the airflow, preventing the flowers from being damaged by impacting the sharp angles or edges of the inner wall of the pipe when they are turned and discharged.

[0015] Preferably, the present invention further includes a vehicle body, a fixing frame, and a conveyor belt; the fixing frame is fixed to the vehicle body, the conveyor belt is fixed to the outer wall of the fixing frame, and the feed end of the conveyor belt is located below the outlet, for receiving and conveying the flowers discharged from the outlet.

[0016] Preferably, in the embodiment including the vehicle body and the conveyor belt, the present invention further includes a collection bin; the collection bin is located at the rear of the vehicle body, and the discharge end of the conveyor belt extends to the opening of the collection bin, so that the flowers can be transported in an orderly manner and stored in a centralized manner.

[0017] Preferably, as a further improvement, the inside of the collection chamber is provided with a flexible cushioning pad, which can absorb the impact energy when the flower falls into the collection chamber, preventing the flower from being damaged by falling collisions or the pressure of subsequent flower stacking.

[0018] Preferably, as another improvement to the conveying process, the conveyor belt is made of a flexible, non-slip material. This material not only provides gentler support but also increases the adhesion of the flowers to the conveyor belt, preventing the flowers from sliding or rolling due to bumps during conveying and reducing friction damage.

[0019] Preferably, in the embodiment including the fixed frame, the present invention also includes a slide rail; the slide rail is fixed to the fixed frame, and the fixed block is slidably connected to the slide rail. This structure allows the head of the entire harvesting auxiliary device to move along a preset trajectory, expanding the operating range and improving the flexibility of operation.

[0020] This utility model has the following beneficial effects:

[0021] 1. This utility model solves the problem of petals being scratched, broken, or squeezed due to positioning deviation, instantaneous impact, and rigid contact during picking and positioning in the prior art by setting a guide cover, a silicone buffer ring, and an adaptive annular petal positioning ring composed of an arc-shaped silicone block, a slider, a spring, and a groove. It achieves a non-destructive positioning effect of precise positioning, flexible buffering, and adaptive clamping.

[0022] 2. This utility model solves the problem of secondary damage caused by mechanical gripping, pipe collision, turning impact, conveying bumps and stacking compression during the collection and transportation of flowers after picking in the prior art by setting up a vacuum pump, hose, folding pipe, guide head with smooth arc inner wall, flexible anti-slip conveyor belt and collection chamber with built-in flexible buffer pad. It achieves the non-destructive collection effect of non-contact suction, flexible transmission and buffer collection throughout the process.

[0023] 3. This utility model, by organically combining the above-mentioned flexible positioning and screening components with the non-destructive collection components, and with the fixed block and fixed frame structure that can move along the slide rail, solves the problem in the prior art that the non-destructive positioning and non-destructive collection links are disconnected and cannot form a complete automated non-destructive operation process. It realizes the non-destructive and automated auxiliary operation of the entire process from positioning to collection, effectively improves the picking integrity rate of Camellia chrysantha flowers, and maximizes the preservation of its ornamental, medicinal and economic value.

[0035] To solve the above-mentioned technical problems, the auxiliary device for non-destructive picking of Camellia chrysantha flowers also includes a collection component 5, and the collection component 5 and the aforementioned positioning and screening component 4 form a specific structural cooperation and communication relationship.

[0036] Please refer to the following carefully. Figure 1 , Figure 2 and Figure 4 The collecting component 5 includes a vacuum pump 51, a hose 52, a folded tube 53, a guide head 54, and an outlet 55.

The suction port of the vacuum pump 51 is connected to the hose 52 or the folded tube 53 to generate a negative pressure airflow within the pipeline of the entire collecting component 5.

[0037] Specifically, the guide head 54 has a smooth, arc-shaped inner wall structure, which is used to guide the movement trajectory of the flower and ensure that the flower is smoothly discharged from the outlet 55.

[0038] For the transportation, carrying and moving of flowers after they are discharged from outlet 55, this embodiment also includes a vehicle body 1, a fixed frame 3, a conveyor belt 7, a collection bin 2 and a slide rail 8. The specific structure and connection relationship will be described later.

[0039] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0040] As a preferred embodiment, please refer to Figure 3 The arc-shaped silicone blocks 44 are evenly distributed around the circumference of the annular petal positioning ring 43.

[0044] Based on the above-described embodiment including the conveyor belt 7, as another further preferred embodiment, the conveyor belt 7 is made of a flexible, non-slip material.

[0045] Based on the above-described embodiment including the conveyor belt 7 and the fixing frame 3, as another further preferred embodiment, please refer to... Figure 1 The device also includes a slide rail 8, which is fixed to the mounting bracket 3, and a fixing block 6 is slidably connected to the slide rail 8.

[0046] The working principle of this utility model's auxiliary device for non-destructive harvesting of Camellia chrysantha flowers is as follows:

[0047] When picking Camellia chrysantha flowers, the guide cover 41, which is fixedly connected to the bottom of the fixed block 6, first guides the flower smoothly along the branch axis under the drive of the robotic arm. The guide cover 41 precisely confines the picking head within the effective working area containing the branch. During the feeding process, the silicone buffer ring 42 in the positioning and screening component 4 actively absorbs instantaneous impact and vibration energy due to its elastic properties, isolating the mechanical force from direct contact with the petals. Subsequently, when the flower enters the annular petal positioning ring 43 along with the branch, the annular petal positioning ring 43 can adaptively adjust according to the thickness of the branch. Specifically, this is achieved through circumferentially evenly distributed arc-shaped silicone blocks 44. When the arc-shaped silicone blocks 44 are squeezed by external force, they will slide smoothly inside the groove 48 on the fixed block 6 under the limiting and guiding action of the slider 45 and the limiting block 46, as well as the synergistic action of the elastic deformation of the spring 47, thereby achieving synchronous adaptive extension and contraction. When the thickness of the branch changes, the spring 47 will be compressed or extended accordingly. Through elastic feedback, it is ensured that the annular petal positioning ring 43 is always in close contact with the surface of the branch. The flexible material of the arc-shaped silicone blocks 44 can further buffer the force during the positioning process.

[0048] After the camellia flowers are picked, the operator starts the vacuum pump 51 in the collection assembly 5. The vacuum pump 51 generates a stable negative pressure, which is then used to form a directional airflow through the hose 52. This airflow gently draws the picked camellia flowers into the folded tube 53. The folded tube 53, due to its foldable nature, can flexibly adapt to the movement of the fixed block 6 as it slides along the preset track to adjust its position via the slide rail 8. Subsequently, the camellia flowers that have entered the folded tube 53 are guided by the airflow to the guide head 54. The guide head 54, through its smooth arc-shaped inner wall structure, precisely guides the movement trajectory of the flowers. Finally, the flowers are smoothly discharged from the outlet 55 and fall onto the conveyor belt 7 fixed to the outer wall of the fixed frame 3. The conveyor belt 7 is made of a flexible, non-slip material and maintains a uniform and stable speed during operation, transporting the flowers in an orderly manner into the collection chamber 2 at the rear of the vehicle body 1. The flexible buffer pads inside the collection chamber 2 further absorb the impact force when the flowers fall in.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
