Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery and agricultural automation production, in particular to a flexible banana supporting device with lateral wrapping properties. Background Art

[0002] Bananas are a staple food in some tropical regions because they are rich in vitamin A and fiber, and their flesh is highly nutritious. However, banana harvesting is still a manual process, typically requiring two or more people: one person to lift and protect the bunches and transport them, and one to cut the stalks. Manual handling of bananas is labor-intensive and inefficient, indirectly impacting the storage and freshness of bananas and, to a certain extent, reducing their economic benefits. To address this, research has been conducted in recent years on automated harvesting machinery for banana plantations. However, current banana harvesting machinery is complex and often utilizes a single gripping mechanism, such as a manipulator. Due to the heavy weight of banana bunches, the manipulator struggles to withstand this load during mechanized harvesting, which can easily lead to problems such as tipping over. Therefore, the design of a flexible banana support device with lateral wrapping capabilities is essential to replace manual handling of banana bunches. This would save significant manpower and resources, reduce mechanical damage to the bunches, enhance the lateral wrapping capability of the bunches during the support process, prevent tipping over, and improve harvesting efficiency.

[0003] Many banana plantations are located in mountainous and hilly areas. Bananas from these mountain orchards are mostly transported by cableway. However, transporting bananas from the trees to the cableway is almost entirely done manually, which is labor-intensive, inefficient, and lacks reliable mechanical equipment. Furthermore, during transport, bananas often collide with each other, directly damaging the bunches and reducing their economic benefits. Therefore, it is practical to design a flexible banana support device with lateral wrapping to facilitate banana transportation, reduce secondary damage, and improve transportation efficiency and economic benefits. Summary of the Invention

[0004] The present invention aims to overcome the shortcomings of the prior art by proposing a flexible banana support device with lateral wrapping. This device replaces manual lifting of banana clusters, overcomes the asymmetric growth of banana fruit bunches, and provides passive, flexible support for the base of the banana cluster during the harvesting process. The device can collaborate with a harvesting robot to reduce the robot's load and minimize mechanical damage to the cluster. Furthermore, the device can also work in conjunction with banana farmers who cut banana stalks to achieve semi-automated harvesting in banana orchards, reducing labor intensity and improving harvesting and transportation efficiency. Furthermore, for banana orchards using mechanized transportation, the device can also serve as an auxiliary support device for banana clusters, preventing secondary damage to the clusters during transportation and improving banana quality.

[0005] The object of the present invention is achieved by the following technical solution: a flexible banana supporting device with lateral wrapping performance, comprising a fixed disc, a base body, a flexible supporting mechanism and a flexible wrapping mechanism; wherein the flexible wrapping mechanism comprises a movable guide column, a compression spring, a lateral wrapping flexible finger, a rigid support plate and a rotating connecting piece; the bottom end of the movable guide column contacts the fixed disc, and the top end of the movable guide column extends out of the guide hole of the base body and is connected to the rotating connecting piece; the compression spring is sleeved on the outside of the movable guide column and is located between the base body and the fixed disc; one end of the rigid support plate is connected to the rotating ear of the base body, and the lateral wrapping flexible finger is connected to the rotating connecting piece through the rigid support plate, and multiple flexible wrapping mechanisms form a flexible supporting claw capable of wrapping the bottom of a banana bunch; the flexible supporting mechanism is mounted on the base body and located at the center of the base, and a through hole for passing the banana axis is opened at the center of the flexible supporting mechanism, the base body and the fixed disc, and the through holes of the three correspond to each other.

The compression spring is sleeved on the outside of the fixed guide column and is located between the base body and the fixed disc.

[0007] Furthermore, the base body includes a cylindrical portion and a disc portion connected in sequence from top to bottom, a plurality of rotating ears are provided along the outer circumference of the cylindrical portion, and a plurality of guide holes are evenly distributed along the outer circumference of the disc portion.

[0008] Furthermore, a groove is formed at the top of the movable guide column for connecting with the bottom of the rotating connecting member.

[0009] Furthermore, the rigid support plate is a 7-shaped support plate, which includes a long-side rigid beam and a short-side support beam; the ends of the long-side rigid beam are connected to the rotating ears of the two base bodies, and the bottom surface of the long-side rigid beam is provided with a plurality of fixing holes for connecting with the fixing blocks that laterally wrap the flexible fingers, and a sliding groove for connecting with the rotating connecting piece; the long-side rigid beam is connected to the short-side support beam, and the angle between the two is an acute angle, so that the short-side support beam is set diagonally upward.

[0010] Furthermore, the flexible supporting mechanism is a flexible hollow bag, which is a thin film hollow structure. Under the squeezing of the banana comb at the bottom of the banana bunch, the flexible hollow bag is deformed, causing the part of the top of the flexible hollow bag that does not contact the bananas to expand and deform upward, adaptively compensating for the height difference of the bananas, and achieving supporting and wrapping of the bottom of the bananas. At the same time, the side surfaces of the flexible hollow bag are deformed radially outward and contact the lateral wrapping flexible fingers, further promoting the lateral wrapping of the banana bunch by the lateral wrapping flexible fingers.

[0011] Furthermore, the laterally wrapped flexible finger includes a fin-like structure and a wing structure, and the wing structure is symmetrically arranged on both sides of the fin-like structure.

[0012] Furthermore, the fin-shaped structure includes a triangular flexible beam, a flexible support beam and a fixed block; the triangular flexible beam includes three flexible beams connected end to end in sequence, and the angle between each two flexible beams is an acute angle. The bottom of the triangular flexible beam is connected to the rigid support plate through a fixed block, so that the bottom of the triangular flexible beam is inclined downward and toward the center of the device, and the flexible support beams have multiple equidistantly arranged inside the triangular flexible beam.

[0013] Furthermore, the wing structure includes connecting columns and dorsal fin structures. The dorsal fin structures are stacked and connected from top to bottom to form a prism structure. Each dorsal fin structure is connected to the fin-shaped structure through a connecting column.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0016] 1) The present invention is a passive supporting device that can effectively replace manual labor in lifting banana bunches without the need for a power source. It can effectively cooperate with a cutting robot or a banana cutter to complete the harvesting process, reducing the load of the picking robot in the prior art, avoiding the overturning problem of the banana harvesting machine, saving labor costs, and reducing labor intensity.

[0017] 2) The present invention can achieve flexible and adaptive wrapping and supporting of banana clusters, and has good adaptability to specific parameters such as the shape and height difference of the bananas. By using flexible hollow sacs, it can effectively overcome the problem of difficulty in supporting due to the asymmetric distribution of banana clusters, adaptively compensate for the height differences of bananas, and achieve stable supporting of banana clusters at different heights, greatly improving the efficiency of banana harvesting and transportation, while significantly reducing mechanical damage to the bottom of the banana cluster.

[0018] 3) The lateral wrapping flexible fingers used in the present invention are flexible fingers with lateral wrapping capabilities. They rely on the elastic deformation of the flexible fingers to achieve the flexible wrapping and supporting function of the banana bunch. Through the deformation of the flexible wing mechanisms of multiple fingers, all-round wrapping of the banana bunch is achieved, improving the stability of the flexible support and wrapping, and can effectively reduce mechanical damage to the banana bunch during the support and transportation process. At the same time, it can achieve a good flexible wrapping and supporting function for banana bunches of different shapes and sizes. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present invention will be further described below with reference to specific embodiments.

[0033] See also Figures 1 to 5 As shown, this embodiment provides a flexible banana supporting device with lateral wrapping properties, comprising a fixed disc 1, a fixed guide post 501, a base body 2, a flexible supporting mechanism, and a flexible wrapping mechanism;

[0034] The fixed disc 1 is located at the bottom of the device, and a concentric circular through hole 102 is opened at its center to accommodate the small axis at the bottom of the banana bunch and limit the movement of the small axis; the base body 2 is generally in the shape of a boss, with a cylindrical portion 202 at the upper part and a disc portion 201 at the lower part. A through hole 203 for passing the banana axis is processed at the center of the base body 2; the cylindrical portion 202 is a thin-walled structure, and a flexible supporting mechanism is arranged inside. The flexible supporting mechanism is a flexible hollow bag 3. A plurality of rotating ears 204 are uniformly distributed circumferentially on the outer circumference of the cylindrical portion 202, and a plurality of guide holes 205 are uniformly distributed circumferentially along the edge of the disc portion 201.

[0035] The flexible wrapping mechanism includes a movable guide column 502, a compression spring 6, a laterally wrapped flexible finger 4, a rigid support plate 7 and a rotating connecting piece 8; the bottom of the fixed guide column 501 is connected to the fixed disc 1, and a boss is provided after the top of the fixed guide column 501 extends out of the guide hole of the base body 2 to play a limiting role, and the bottom end of the movable guide column 502 contacts the fixed disc 1, and a groove is opened at the top of the movable guide column 502, and the top end of the movable guide column 502 extends out of the guide hole of the base body 1 and is connected to a radially arranged rotating connecting piece 8; the compression spring 6 is sleeved on the outside of the fixed guide column 501 and the movable guide column 502, and the compression spring 6 is located between the base body 2 and the fixed disc 1; the rigid support plate 7 is evenly distributed along the circumference on the outer periphery of the base body 2 and is radially arranged, and the rigid support plate 7 is in the shape of a 7 as a whole, and the front end of the rigid support plate 7 is connected to the two rotating ears 204 of the base body 2, so that the rigid support plate 7 can rotate around the rotating ears 204 The central rotation is performed, and a slide groove 704 and a plurality of rectangular fixing holes 703 are processed on the longer plate 701 of the rigid support plate. The rectangular fixing holes 703 are used to connect the lateral wrapping flexible fingers 4. The bottom of the rotating connecting member 8 is connected to the groove at the top of the movable guide column 502, and the top of the rotating connecting member 8 is connected to the slide groove 704 of the rigid support plate 7; the number of the lateral wrapping flexible fingers 4 is consistent with the number of the rigid support plate 7, the movable guide column 502, and the rotating connecting member 8. One lateral wrapping flexible finger 4 is correspondingly installed on one rigid support plate 7, and each rigid support plate 7 is connected to one movable guide column 502 through a rotating connecting member 8; the lateral wrapping flexible fingers 4 are made of flexible material and are evenly distributed along the circumference on the outer periphery of the base body in a radial arrangement. The bottom of the lateral wrapping flexible fingers 4 is connected to the rigid support plate 7, and multiple lateral wrapping flexible fingers 4 form a flexible holding claw that can wrap the bottom of the banana bunch;

[0036] During the supporting process, the banana comb 901 at the bottom of the banana bunch 9 presses down the flexible hollow balloon 3, causing the flexible hollow balloon 3 to deform. The top surface of the flexible hollow balloon 3 deforms upward to fill and wrap the area around the banana axis 902, achieving adaptive compensation for the height difference of the banana comb, ensuring the stability of the banana bunch 9 during the supporting process. At the same time, the side of the flexible hollow balloon 3 deforms radially outward and contacts the middle fin-shaped structure of the side-wrapping flexible finger 4, prompting the side-wrapping flexible finger 4 to deform and wrap toward the center of the device. The banana bunch 9 continues to press downward by its own weight, and then The flexible hollow bag 3 and the base body 2 are moved downward to the corresponding positions. At the same time, the movable guide column 502 drives the rigid support plate 7 to rotate around the center of the rotating ear 204 through the rotating connecting piece 8, so that the side-wrapping flexible fingers 4 are deformed and wrapped toward the center of the device. When the banana bunch is further pressed downward, the multiple side-wrapping flexible fingers 4 are squeezed by the banana combs 901 at different heights on the circumference of the banana bunch 9 and deformed to different degrees. By adaptively adapting the banana comb and wrapping the banana comb laterally, the passive wrapping and supporting of the banana bunch is finally achieved.

[0037] Among them, see Figures 1 to 2 As shown, the flexible hollow balloon 3 is a thin film hollow structure made of flexible material, with a through hole for passing the banana axis processed at the center, and a certain amount of gas is filled inside. During the supporting operation, the banana comb 901 at the bottom of the banana bunch first contacts the flexible hollow balloon 3 and deforms it, prompting the top part of the flexible hollow balloon 3 that does not contact the banana to expand and deform upward, adaptively compensating for the height difference of the banana, and realizing the supporting and wrapping of the bottom of the banana. The side part of the flexible hollow balloon 3 deforms radially outward and contacts the side wrapping flexible fingers 4, further promoting the side wrapping of the banana bunch by the side wrapping flexible fingers 4.

[0038] See also Figure 2 、 Figure 5 As shown, the rigid support plate 7 is in a 7-shaped structure as a whole, which includes a long-side rigid beam 701 and a short-side support beam 702. The long-side rigid beam 701 is obliquely upward away from the pointed end toward the center of the flexible supporting claw, and the short-side support beam 702 is connected to the long-side rigid beam 701 to form a 7-shaped structure, and the angle between the two is an acute angle. The bottom surface of the long-side rigid beam 701 is processed with a plurality of fixing holes 703 for connecting with the fixed block that laterally wraps the flexible finger 4, and is processed with a slide groove 704 for connecting with the rotating connector 8.

[0039] See also Figure 1 、 Figures 6 to 13As shown, the lateral wrapping flexible finger 4 includes a fin-like structure 401 and two side wing structures 402, and the side wing structures 402 are symmetrically distributed on both sides of the fin-like structure 401; when supporting bananas, the fin-like structure 401 bends after contacting the banana and longitudinally wraps the banana comb 901. The lateral deformation of the flexible hollow bag 3 also produces a contact effect on the middle fin-like structure 401, promoting the longitudinal deformation and wrapping of the fin-like structure 401. At the same time, the side wing structures 402 on the left and right sides will also bend and deform under the combined action of the deformation of the fin-like structure 401 and the pressure of the banana, and then wrap the banana comb 901 from both sides, thereby improving the lateral wrapping ability during the banana bunch supporting process.

[0040] See also Figure 2 、 Figure 9 As shown, the fin-shaped structure 401 includes a triangular flexible beam 4011, a flexible support beam 4012 and a fixed block 4013; the triangular flexible beam 4011 is composed of three flexible beams connected, and the angle between each two flexible beams is an acute angle, the triangular flexible beam 4012 is tilted at the top of the long side rigid beam 701, one side of the triangular flexible beam 4011 is in contact with the short side support beam 702, and its bottom is tilted downward and toward the center of the flexible supporting claw, the interior of the triangular flexible beam 4011 is evenly distributed with a plurality of flexible support beams 4012 of increasing length, which are tilted upward at a preset angle to the triangular flexible beam 4011 and toward the center of the flexible supporting claw, the two ends of each flexible support beam 4012 are respectively connected to the two inner side surfaces of the triangular flexible beam 4011, and a plurality of fixed blocks 4013 are connected to the lower side edge of the bottom of the triangular flexible beam 4011 for connecting with the fixing hole 703 of the rigid support plate 7.

[0041] Preferably, the surface of the flexible beam is rectangular or trapezoidal.

[0042] See also Figures 6 to 10 As shown, the side wing structure 402 includes a plurality of connecting columns 4021 and a dorsal fin structure 4022. The plurality of dorsal fin structures 4022 are arranged in sequence from top to bottom to form a prism structure. Each dorsal fin structure 4022 is connected to the middle fin-shaped structure 401 through two connecting columns 4021.

[0043] The dorsal fin structure 4022 includes a π-shaped flexible beam 4023 and a flexible cross beam 4024. The π-shaped flexible beam 4023 is tilted on both sides of the middle fin-shaped structure 401. A plurality of flexible cross beams 4024 with increasing lengths are evenly distributed inside the π-shaped flexible beam 4023, which are tilted upward at an angle to the π-shaped flexible beam 4023 and wrap laterally around the center of the flexible finger 4. The two ends of each flexible cross beam 4024 are respectively connected to the two inner side surfaces of the π-shaped flexible beam 4023. The open end of the bottom of the π-shaped flexible beam 4023 is tilted downward, and its two ends are respectively connected to the end faces of the triangular flexible beam 4011 of the middle fin-shaped structure 401 through two connecting columns 4021.

[0044] The π-shaped flexible beam 4022 is composed of a top flexible crossbeam 4026 and two flexible side beams. The angle between the two flexible side beams and the top flexible crossbeam 4026 is an acute angle. The two flexible side beams include a long beam 4027 and a short beam 4025. The short beam 4025 is connected to the inner side of the fin-shaped structure 401, and the long beam 4027 is connected to the outer side of the fin-shaped structure 401. The height of the short beam 4025 is greater than the height of the long beam 4027, so that the entire π-shaped flexible beam 4022 is inclined upward at a preset angle and wraps laterally around the center of the flexible finger 4.

[0045] Preferably, the surface of the flexible beam is rectangular or trapezoidal.

[0046] The passivity and adaptability of this embodiment are reflected in the following aspects: the flexible banana supporting device with lateral wrapping does not require an additional power source, and relies on the pressure of the banana bunch to achieve the deformation and lateral wrapping supporting operation. The flexible hollow bag can passively adapt to the height difference characteristics of the target banana bunch, and the flexible fingers can passively adapt to the size and shape of different banana bunches through lateral wrapping. The adaptive and lateral wrapping effects are shown in the following figure. Figures 11 to 13 shown.

[0047] The flexible banana supporting device with lateral wrapping properties of this embodiment is not only suitable for banana harvesting, but can also be used for banana plantation transportation by adjusting factors such as the device's installation position, the size of the work carrier, and the travel speed. By adding fixing components to the flexible banana supporting device with lateral wrapping properties, it can be used in banana plantation cableway transportation to prevent collisions between banana clusters.
