Description
Technical Field
[0001] This utility model relates to the field of harvesting device technology, specifically to an orchard harvesting device. Background Technology
[0002] Traditional orchard harvesting methods mainly rely on manual picking, which requires pickers to stand on the ground for long periods of time or use simple ladders and other tools to work. This is not only labor-intensive but also inefficient. The limitations of manual picking become more and more obvious, especially when dealing with large orchards and tall fruit trees.
[0003] While some existing orchard harvesting devices attempt to address these issues to some extent, they still have many shortcomings. For example, the harvesting platform area of some devices is fixed and cannot be flexibly adjusted according to the distribution of fruit trees and the growth position of the fruit. This makes it difficult for harvesters to complete the harvesting task comprehensively and efficiently in some narrow areas or areas with uneven fruit distribution. Utility Model Content

Multiple harvesting platforms are installed at suitable locations on the frame. The surface of the sliding cavity is smooth, and the extension platform slides in and out within the cavity. The extension platform allows the operator to flexibly adjust the working area of the harvesting operation according to the actual needs of the harvesting work.
[0039] The addition of multiple picking platforms increases the area for simultaneous picking operations, improving picking efficiency. The design of the sliding cavity and extension platform allows the picking area to be flexibly adjusted according to the distribution of fruit trees in the orchard and the operational needs of the pickers. In narrow rows of fruit trees, the extension platform can be retracted for easy movement of the device; while in areas with denser fruit trees or wider fruit distribution, the extension platform can be slid out to expand the picking range, effectively improving the adaptability of the picking device to different orchard environments.

[0049] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are merely some embodiments of this utility model. For those skilled in the art, they can be understood as further technical solutions without creative effort. In some drawings, components with the same structure or function are only schematically illustrated, or only one is marked. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."
[0050] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0051] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0052] Reference Figures 1 to 7 The first embodiment of this utility model proposes an orchard picking device, including a frame 1; a plurality of picking platforms 2, all of which are set on the frame 1, and each picking platform 2 has a sliding cavity 21; a plurality of extension platforms 3, which are correspondingly slidably set in the sliding cavity 21, and the extension platforms 3 slide into or out of the sliding cavity 21 after sliding.
[0053] In this embodiment, the frame 1 serves as the basic support structure of the entire harvesting device. It is made of a sturdy yet lightweight metal material (such as aluminum alloy), and its stability and integrity are ensured through welding or bolt connections to support the weight of the harvesting platform 2 and other components, while also adapting to the movement requirements of different terrains within the orchard. Multiple harvesting platforms 2 are installed at suitable locations on the frame 1. The surface of the sliding cavity 21 is smooth, and the extension platform 3 slides in and out within the sliding cavity 21. The function of the extension platform 3 is to allow the operator to flexibly adjust the working area of the harvesting operation according to the actual needs of the harvesting work.
[0054] The addition of multiple picking platforms 2 increases the area for simultaneous picking operations, improving picking efficiency. The design of the sliding cavity 21 and the extension platform 3 allows the picking area to be flexibly adjusted according to the distribution of fruit trees in the orchard and the operational needs of the pickers. In narrow rows of fruit trees, the extension platform 3 can be retracted for easy movement of the device; while in areas with denser fruit trees or wider fruit distribution, the extension platform 3 can be slid out to expand the picking range, effectively improving the adaptability of the picking device to different orchard environments.
[0055] Furthermore, the first mounting bracket 22 is mounted on the vehicle frame 1; the pedal 23 has a first vertical part 231, a horizontal part 232 and a second vertical part 233 arranged in sequence, the first vertical part 231 and the second vertical part 233 are mounted on the first mounting bracket 22, and a sliding cavity 21 is formed between the horizontal part 232 and the first mounting bracket 22.
[0056] In this embodiment, the first mounting bracket 22 is made of a suitable metal profile (such as channel steel or square steel), and is processed into the required shape and size through processes such as cutting, bending and welding to ensure that it has sufficient strength and stability to provide support for the foot pedal 23. The mounting bracket is connected to the frame 1 by bolts or welding.
[0057] The foot pedal 23 has a non-slip metal surface (such as patterned steel plate), which is formed into the shape of a first vertical part 231, a horizontal part 232, and a second vertical part 233 through stamping or bending processes. The first vertical part 231 and the second vertical part 233 are fixed to the first mounting bracket 22 by welding or bolting. The gap between the horizontal part 232 and the first mounting bracket 22 is the sliding cavity 21.
[0058] The first mounting frame 22 provides a stable support structure for the entire picking platform 2, ensuring the safety of the picking operation. The shape of the foot pedal 23 is designed to facilitate the standing and operation of the picking personnel. The formed sliding cavity 21 utilizes the space between the foot pedal 23 and the first mounting frame 22 without taking up too much additional device volume, making the structure of the picking device more compact and reasonable.
[0059] Furthermore, the first mounting bracket 22 has a sliding channel 221, and the second mounting bracket 31 is slidably disposed within the sliding channel 221; one end of the extension plate 32 is slidably disposed within the sliding cavity 21, and the other end is disposed on the second mounting bracket 31.
[0060] In this embodiment, the first mounting frame 22 has a hollow square tube structure, and the hollow part of the square tube is the sliding channel 221. This structure reduces the weight of the entire device. The second mounting frame 31 also has a square tube structure. The square tube of the second mounting frame 31 is smaller in size and can be inserted into the sliding channel 221 and slide along the sliding channel 221. In this embodiment, a telescopic cylinder is designed on the first mounting frame 22. The telescopic end of the telescopic cylinder is set on the second mounting frame 31. After the telescopic cylinder extends and retracts, it drives the second mounting frame 31 to extend and retract. The extension plate 32 slides in the sliding cavity 21, and the other end is connected to the second mounting frame 31 by welding or bolting. This allows the extension plate 32 to move with the second mounting frame 31 during the extension and retraction of the telescopic cylinder, realizing the effective expansion and contraction of the harvesting area.
[0061] Furthermore, the lower end face of the second mounting bracket 31 has a first sliding groove 311, and the upper end face has a second sliding groove 312. There are several first rollers 4, which are rotatably arranged in the first sliding groove 311 at intervals. The first rollers 4 abut against the lower end face of the sliding channel 221. The second rollers 5 are rotatably arranged in the second sliding groove 312, and the second rollers 5 abut against the upper end face of the sliding channel 221.
[0062] In this embodiment, a first groove 311 and a second groove 312 are respectively machined on the lower end face and the upper end face of the second mounting bracket 31. The first roller 4 and the second roller 5 can rotate freely in the first groove 311 and the second groove 312 without coming out.
[0063] The first roller 4 and the second roller 5 are made of wear-resistant, high-load-bearing rubber or nylon material and are installed in the first slide groove 311 or the second slide groove 312 through the cooperation of shafts and bearings. During installation, the position and spacing of the first roller 4 and the second roller 5 are adjusted so that the first roller 4 is in close contact with the lower end face of the sliding channel 221 and the second roller 5 is in close contact with the upper end face of the sliding channel 221. Thus, during the sliding of the second mounting frame 31, the first roller 4 and the second roller 5 can effectively reduce friction and play a supporting and guiding role, making the sliding of the extension platform 3 smoother and more stable.
[0064] The placement of the first roller 4 and the second roller 5 further reduces the friction between the expansion platform 3 and the sliding channel 221, making the sliding of the expansion platform 3 easier, reducing energy loss and mechanical wear, and extending the service life of the device. At the same time, the first roller 4 and the second roller 5 have a guiding function, preventing jamming or collisions caused by misalignment.
[0065] Furthermore, several first mounting brackets 22 are arranged sequentially on the frame 1 from high to low.
[0066] In this embodiment, the height of the first mounting frame 22 is reasonably designed and adjusted according to the height distribution of fruit trees in the orchard and the actual needs of the harvesting operation. The height of the first mounting frame 22 varies. The first mounting frame 22 is fixed to the frame 1 in descending order by welding or bolting, ensuring that the height difference of each harvesting platform 2 can meet the convenience requirements of harvesters picking fruits at different heights, and that it is not easy to tip over during movement and operation.
[0067] This staggered arrangement of picking platforms 2 better adapts to the diverse heights of fruit trees in the orchard. Pickers can choose the appropriate height of picking platform 2 to work based on the actual height of the fruit trees, eliminating the need for frequent bending or stretching, thus reducing labor intensity and improving picking efficiency and work accuracy.
[0068] Furthermore, the upper frame 6 is movably mounted on the frame 1; the mounting block 7 is mounted on the frame 1; one end of the first link 8 is rotatably mounted on the mounting block 7, and the other end is rotatably mounted on the upper frame 6; one end of the second link 9 is rotatably mounted on the mounting block 7, and the other end is rotatably mounted on the upper frame 6, forming a parallel four-bar linkage between the first link 8, the second link 9, the mounting block 7, and the upper frame 6.
[0069] In this embodiment, a fixed mounting block 7 is installed on the frame 1, with the mounting block 7 pointing vertically downwards. This provides stable support and a rotational connection point for the first link 8 and the second link 9. The first link 8 and the second link 9 are metal rods of appropriate length and strength, with their ends connected to the mounting block 7 and the upper frame 6 respectively via pins. This ensures the rotational flexibility of the connection points, allowing the upper frame 6 to move smoothly relative to the frame 1 under the drive of the parallel four-bar linkage, achieving specific motion trajectories and functions.
[0070] The design of the parallel four-bar linkage makes the movement of the upper frame 6 more flexible and precise, and can be quickly and accurately adjusted according to different stages and needs of the picking operation. This makes it easier for pickers to transport the picked fruits and fruit baskets to the frame 1, reducing the workload and labor intensity of manual handling.
[0071] Furthermore, the conveyor 10 is cyclically arranged on the frame 1. After the upper frame 6 moves, it is used to convey fruit baskets onto the conveyor 10. The lower frame 11 is flexibly arranged on the frame 1. After the lower frame 11 is flexibly arranged, it is used to support the fruit baskets on the conveyor 10. The conveyor 10 consists of two conveyor belts, which are spaced apart on the frame 1. The lifting platform 12 is flexibly arranged on the frame 1, located between the two conveyor belts. After the lifting platform 12 is flexibly arranged, it is used to drive the fruit baskets to move up and down.
[0072] In this embodiment, two conveyor belts are installed parallel and spaced apart on the frame 1. Fruit baskets can be placed on top of the two conveyor belts. By adjusting the supports and tensioning devices of the conveyor belts, the flatness and spacing of the two conveyor belts are ensured to meet the requirements for transporting fruit baskets. The fruit baskets move under the drive of the two conveyor belts without shifting or getting stuck. The surface of the conveyor belts is made of anti-slip material to increase the friction between the fruit baskets and the conveyor belts, preventing the fruit baskets from slipping during transportation.
[0073] The lifting platform 12 is mounted on the vehicle frame 1 using a metal frame structure. Its lifting function is achieved through a hydraulic system, electric screw jack, or pneumatic device. The lifting height and speed of the lifting platform 12 are precisely controlled by a control system, enabling it to raise fruit baskets from a lower position to a higher one, allowing pickers to place the fruit from a higher position. After the lower frame 11 is raised to the same height as the conveyor 10, the conveyor 10 continues to move, transporting the fruit baskets directly onto the lower frame 11. The lower frame 11 then descends and unloads the fruit.
[0074] Furthermore, the first mounting bracket 22 is ellipsably mounted on the frame 1, the second mounting bracket 31 has a first sliding space, the first step 13 is ellipsably mounted within the first sliding space and has a second sliding space; there are several second steps 14, one of the edge second steps 14 is slidably mounted within the second sliding space and has a third sliding space, and adjacent second steps 14 are slidably mounted within the third sliding space of another adjacent second step 14; the third step 15 is mounted on the frame 1 and has a fourth sliding space, and another edge second step 14 is ellipsably mounted within the fourth sliding space.
[0075] In this embodiment, after the first mounting frame 22 rises a certain distance, the lower end surface of the first sliding space on the first mounting frame 22 contacts the first step 13, causing the first step 13 to rise. Similarly, the first step 13, several second steps 14 and third steps 15 are arranged from high to low in sequence. When the first mounting frame 22 descends, the first mounting frame 22 descends a certain distance, and the upper end surface of the first sliding space on the first mounting frame 22 contacts the first step 13, causing the first step 13 to descend. Similarly, the process continues.
[0076] Furthermore, there are several third rollers 16 arranged sequentially on the upper frame 6 and the lower frame 11 along the fruit basket conveying direction. When the upper frame 6 moves to the same height as the conveyor 10, the third rollers 16 are connected to one conveyor belt. There are several fourth rollers 17 arranged sequentially on the upper frame 6 and the lower frame 11 along the fruit basket conveying direction. When the upper frame 6 moves to the same height as the conveyor 10, the fourth rollers 17 are connected to another conveyor belt. After the third rollers 16 and the fourth rollers 17 rotate, the fruit basket can be conveyed onto the conveyor 10.
[0077] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
