Description

Technical Field

[0001] This utility model relates to the technical field of fruit tree harvesting auxiliary devices, specifically a buffer-type fruit tree harvesting auxiliary device. Background Technology

[0002] The fruit industry is an important part of my country's agriculture, with pome and stone fruits such as apples, pears, and peaches accounting for a large proportion. These fruits have high economic value, and their market price is closely related to their appearance and quality (such as the smoothness of the surface, the absence of bruises, rust spots, etc.). Therefore, minimizing mechanical damage during harvesting is crucial to ensuring the economic benefits for fruit farmers.

[0003] Currently, harvesting fruit from higher locations (such as the upper and middle parts of the tree canopy) still primarily relies on manual labor. Fruit growers often use ladders and high-pole shears for this task. The common practice is for harvesters to cut the fruit from a height and then directly drop it into collection bags or baskets suspended from the branches or held by ground personnel. However, this method has significant drawbacks: the fruit undergoes a free fall from the point of cut into the container, resulting in violent collisions and compression with the bottom and sides of the container or with other fruit already in it. Fruits like apples, pears, and peaches, while relatively hard, are also brittle, making them highly susceptible to developing subtle, invisible bruises or marks ("bumps") on the peel. These damages gradually become apparent during subsequent storage, transportation, and sales, leading to browning, rotting, and a significant decline in appearance and marketability, resulting in substantial economic losses.

[0004] To address this issue, some cushioning harvesting devices have emerged in existing technologies, such as padding the inside of the collection bag. However, these simple measures have limited cushioning effects, especially when the harvesting height is high and the fruit's falling speed and impact force are significant, their protective function is insufficient. Furthermore, a single collection bag cannot adapt to the varying heights of different fruit trees, resulting in poor versatility. Utility Model Content

[0005] To address the problem that the simple buffering measures in the above-mentioned technologies are insufficient in protection and prone to collisions, this utility model provides a buffered fruit tree harvesting auxiliary device.

[0006] The technical solution of this utility model is as follows: A buffer-type fruit tree harvesting auxiliary device includes multiple conveying pipes, which are detachably connected by clamps. Multiple elastic columns are provided on the inner side of the clamps, and the non-fixed ends of the elastic columns face the axis of the clamps. The inside of the conveying pipe is also provided with an elastic layer, the outer side of which is closely attached to the inner wall of the conveying pipe and is detachably connected to the conveying pipe. A fruit-receiving basket is also provided at the top of the uppermost conveying pipe, and the fruit-receiving basket is detachable from the conveying pipe.

[0007] As a preferred technical solution, the bottommost conveying pipe is designed with a bent pipe structure, and a net bag is provided at the end of the bent pipe away from the clamp.

[0008] To reduce the falling speed of the fruit and prevent it from colliding with the fruit due to excessive speed, multiple elastic columns are evenly distributed on the inside of the clamp, and the elastic columns can swing in any direction.

[0009] Furthermore, in the aforementioned buffer-type fruit tree harvesting auxiliary device, the elastic column and elastic layer are made of polyether or polyurethane foam material, and the cross-sectional shape of the elastic column is one of circular, elliptical or wavy.

[0010] To reduce bumps and knocks during harvesting, an elastic layer is provided on the inner wall of the fruit receiving basket, and the elastic layer is tightly attached to the inner wall of the fruit receiving basket.

[0011] Furthermore, in the aforementioned buffered fruit tree harvesting auxiliary device, the thickness of the elastic layer is 3mm to 10mm, and a raised corrugated or dot-matrix buffer structure is provided on the side of the layer away from the conveying pipe.

[0012] As a preferred technical solution, the movement of the elastic layer located on the inner wall of the conveying pipeline is restricted at both ends by the cooperation between the receiving basket and the clamp or adjacent clamp.

[0013] To complement other picking devices and enhance their picking assistance, the outer surface of the clamp is also provided with a snap-fit ​​ring, which snaps onto the surface of the picking device.

[0014] Furthermore, in the aforementioned buffer-type fruit tree harvesting auxiliary device, a support handle is also provided on the outer surface of the conveying pipe, and the support handle is detachably connected to the conveying pipe located at the bottom.

[0015] The beneficial effects of this utility model are as follows: This invention employs multiple conveying pipes connected by clamps, with multiple elastic columns that can swing in any direction set on the inner side of the clamp's middle layer. Simultaneously, an elastic layer with a corrugated or dot-matrix buffer structure is set throughout the conveying pipe. During the fall, the fruit collides with the elastic columns, changing its trajectory to dissipate energy, and makes soft contact with the inner wall of the elastic layer. This effectively avoids the impact damage caused by the fruit's hard contact with the pipe wall during fall, thus maximizing the preservation of the fruit's appearance quality and commercial value.

[0016] Furthermore, the upper and lower layers of the clamp are detachably connected to the conveying pipe, and components such as the fruit receiving basket and support handle are also detachable. This modular structure not only facilitates flexible assembly and adjustment of the device length according to the height of the fruit tree, but also greatly facilitates the carrying and transportation of the device. Further, the curved conveying pipe at the bottom and the net at the end guide and catch the falling fruit, preventing it from popping out or falling again. The elastic layer on the inner wall of the fruit receiving basket also effectively cushions the initial impact after the fruit leaves the tree. Attached Figure Description

[0017] The advantages and solutions of this application will become clear to those skilled in the art upon reading the following detailed description of preferred embodiments. The accompanying drawings are for illustrative purposes only and are not intended to limit the scope of this invention.

[0020] Example like Figure 1-3 The present invention provides a buffer-type fruit tree picking assistance device, the purpose of which is to solve the problem of severe damage to fruits picked from heights due to free fall and collision with hard containers in the prior art. This embodiment provides a buffer-type fruit tree picking assistance device, including multiple conveying pipes 1, which are detachably connected by clamps 3, and along the axial direction of the clamps 3, the two sides of the clamps 3 are respectively connected to different conveying pipes 1.

[0021] Multiple elastic posts 31 are provided on the inner side of the clamp 3, and the multiple elastic posts 31 are evenly distributed on the inner wall of the clamp 3. In this embodiment, eight elastic posts 31 are provided on the inner side of each clamp 3. The elastic posts 31 are made of polyether or polyurethane foam material, and the cross-sectional shape of the elastic posts 31 is one of circular, elliptical or wavy. In this embodiment, the material of the elastic posts 31 is polyurethane foam, and its cross-sectional shape is circular. One end of the elastic post 31 is fixed to the inner side of the clamp 3, and the non-fixed end extends freely toward the axis of the clamp 3. Due to its soft material, the elastic post 31 can swing in any direction under the action of external force. When the fruit falls and passes the position of the clamp 3, it will collide with these elastic posts 31, thereby effectively consuming its falling kinetic energy and changing its trajectory, avoiding vertical acceleration during the fall.

[0022] To further provide full-process cushioning, a removable elastic layer 4 is provided inside each section of the conveying pipe 1. The elastic layer 4 is made of polyether or polyurethane foam material with a thickness of 3mm to 10mm. In this embodiment, the elastic layer 4 is made of polyether foam material with a thickness of 5mm. A fruit receiving basket 2 is detachably installed on the top of the uppermost conveying pipe 1. In this example, the fruit receiving basket 2 is connected to the conveying pipe 1 by threads. The inner wall of the fruit receiving basket 2 is also adhered with the same elastic layer 4 as inside the conveying pipe 1, ensuring that the fruit is cushioned and protected from the moment it is cut from the tree and falls into the fruit receiving basket 2.

[0023] Furthermore, to further plan the fruit's trajectory, reduce its descent speed, and disperse impact force, a raised corrugated or dot-matrix buffer structure is provided on the surface of the elastic layer 4 away from the inner wall of the conveying pipe 1. In this embodiment, the side of the elastic layer 4 away from the inner wall of the conveying pipe 1 is provided with a raised dot-matrix buffer structure. The elastic layer 4 is tightly fitted to the inner wall of the conveying pipe 1, and its two ends are restricted by the mating fit between the fruit receiving basket 2 and the clamp 3 or adjacent clamp 3, thereby preventing displacement during use. The fruit is in contact with the soft elastic layer 4 throughout its descent, avoiding direct collision with the hard pipe wall.

[0024] To facilitate securing the entire device to the surface of the picking ladder or shears, a snap-fit ​​ring 5 is integrally formed on the outer surface of the clamp. The snap-fit ​​ring 5 can be easily snapped into and fixed to an external support. For easy hand operation by pickers, a support handle 6 is installed on the outside of the lowermost conveying pipe 1 via a snap-fit ​​connection. Simultaneously, the lowermost conveying pipe 1 is designed as a curved pipe structure, with a soft net (not shown in the figure) fitted at its outlet end to ultimately catch the sufficiently cushioned fruit and prevent it from rolling off.

[0025] Please refer to the appendix. Figure 1-3In this embodiment, the fruit-receiving basket 2 is first connected to one end of one of the conveying pipes 1. An elastic layer 4 is then laid on the surface of the fruit-receiving basket 2 and the inner wall of the conveying pipe 1. A clamp 3 is installed at the end of the conveying pipe 1 where the fruit-receiving basket 2 is not installed. The process of "connecting a new conveying pipe 1 - laying the elastic layer 4 inside the pipe - installing the clamp 3 at the joint" is repeated according to the actual height of the target fruit tree until the required length is reached. Finally, a bent conveying pipe 1 is installed at the end of the last clamp 3, and a net bag is securely connected to its outlet end, completing the assembly of the entire device. The detachable connection design between the components makes the assembly process simple and quick, and facilitates transportation and storage.

[0026] The user holds the device by the support handle 6 or secures it with the snap ring 5, aligning the fruit-collecting basket 2 with the fruit at a higher position. After being cut, the fruit first falls into the fruit-collecting basket 2 and receives initial cushioning, then slides into the conveyor tube 1. Within the channel composed of multiple layers of conveyor tubes 1, the fruit continuously rubs against the elastic layer 4 with a dot-matrix structure, slowing it down. As it passes each snap ring 3, it collides with the multi-directionally swinging elastic column 31, dissipating energy and changing direction, thus greatly reducing the downward force. Finally, guided by the curved tube, the fruit gently falls into the net bag at the end, completing the entire damage-free harvesting process.
