It includes a frame, a storage platform mounted on the frame, and a harvesting platform located above the storage platform. The storage platform is used to store fruit baskets, and the harvesting platform is used to carry workers. A transfer device is lifted and mounted on the frame for transferring fruit baskets between the harvesting platform and the storage platform.

Description

Technical Field

[0001] This utility model relates to the field of harvesting equipment technology, specifically to a novel self-propelled electric controlled harvesting and transportation platform. Background Technology

[0002] In agricultural planting scenarios such as orchards and vegetable gardens, the transportation of fruits and vegetables after harvesting is crucial. Workers typically need to operate at different heights (such as different branches of fruit trees or different ridge heights for vegetables). After harvesting, the fruits and vegetables need to be promptly transferred to the storage area before being transported out of the planting area.

[0003] In existing technologies, most fruit picking and transportation platforms adopt a fixed structure design, typically consisting of a picking platform for carrying workers and a storage platform for storing fruit baskets, connected by simple supports or channels. To facilitate the transfer of fruit baskets between the picking and storage platforms, some platforms have an outward-extending support structure between them to facilitate the transfer of fruit baskets.

[0004] However, this fixed-structure support device has a significant drawback: because the support structure cannot be stowed away, the overall lateral dimensions of the harvesting and transportation platform are quite large. When traveling through narrow passages in orchards or vegetable gardens, especially when turning or avoiding obstacles such as fruit trees and field ridges, the excessive size makes it difficult for the platform to pass smoothly. This not only increases the risk of collisions with surrounding objects, causing equipment damage or fruit and vegetable spoilage, but also reduces the efficiency of harvesting and transportation and increases the difficulty of operations. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this utility model provide a novel self-propelled electric controlled harvesting and transportation platform, which solves the technical problem in the related technology that harvesting and transportation platforms are difficult to pass smoothly through narrow sections due to their excessive size.

[0006] According to one aspect, at least one embodiment of the present invention provides a novel self-propelled, electrically controlled harvesting and transportation platform, comprising:

[0007] The vehicle frame is equipped with a storage platform and a picking platform located above the storage platform. The storage platform is used to store fruit baskets, and the picking platform is used to support staff.

[0008] A transfer device is provided, which is ellipsably mounted on the frame and is used to transfer fruit baskets between the picking platform and the storage platform. The transfer device includes a frame and a support frame. The frame is ellipsably mounted on the frame, and the support frame is rotatably mounted on the frame. The transfer device has a storage state and a carrying state. When the transfer device is in the storage state, the support frame rotates and moves closer to the frame. When the transfer device is in the carrying state, the support frame rotates and moves away from the frame to carry the fruit baskets.

[0009] For example, in a novel self-propelled electric controlled harvesting and transportation platform provided in at least one embodiment of this utility model, the transfer device further includes a locking device disposed between the frame and the support frame. The locking device is used to limit the position of the support frame, and the locking device includes:

[0010] The base is mounted on the frame.

[0011] A rotating component is rotatably mounted on the rotating shaft of the support frame. The rotating component has several helical teeth along the circumferential direction, and a groove is formed between two helical teeth.

[0012] A limiting member is rotatably mounted on the base, and the limiting member can be inserted into the groove to put the locking device in a locked state.

[0013] For example, in a novel self-propelled electric controlled harvesting and transportation platform provided in at least one embodiment of this utility model, the helical teeth are configured such that the upper end face of the helical teeth is an avoidance slope, and the locking device further includes an elastic member disposed between the limiting member and the base, the elastic member being used to elastically pull the limiting member so that the limiting member is inserted into the groove; the avoidance slope is configured such that when the carrier frame rotates to change the transfer device from a carrying state to a storage state, the end of the limiting member slides along the avoidance slope and then inserts into the adjacent groove.

[0014] For example, in a novel self-propelled electric controlled harvesting and transportation platform provided in at least one embodiment of this utility model, the limiting member is provided with a handle, and the handle can drive the limiting member to rotate so that the limiting member is disengaged from the groove.

[0015] For example, in a novel self-propelled electric controlled harvesting and transportation platform provided in at least one embodiment of the present invention, the harvesting platform is provided with a transportation device, the transportation device includes a plurality of rotating pulleys, the pulleys are configured such that the fruit and vegetable box can slide on the transportation device via the plurality of pulleys.

[0016] For example, in a novel self-propelled electric controlled harvesting and transportation platform provided in at least one embodiment of this utility model, the storage platform is provided with a transportation device two, the transportation device two includes a plurality of rotating pulleys two, the pulleys two are configured so that the fruit and vegetable box can slide on the transportation device two through the plurality of pulleys two.

[0017] For example, in a novel self-propelled electric controlled harvesting and transportation platform provided in at least one embodiment of this utility model, a plurality of pulleys are rotatably provided on the support frame.

[0018] For example, in a novel self-propelled electric controlled harvesting and transportation platform provided in at least one embodiment of this utility model, the transfer device further includes:

[0019] A telescopic component is mounted on the vehicle frame and is used to drive the transfer device to lift and lower.

[0020] A chain, one end of which is disposed at the fixed end of the telescopic member, and the other end is connected to the frame. The telescopic end of the telescopic member is provided with a sprocket for tensioning the chain.

[0021] For example, in a novel self-propelled electric controlled harvesting and transportation platform provided in at least one embodiment of this utility model, the storage platform is provided with fences on both sides, and the fences are rotatably mounted on the vehicle frame;

[0022] The picking platform is equipped with protective railings.

[0023] For example, in a novel self-propelled electric controlled harvesting and transportation platform provided in at least one embodiment of this utility model, the number of the first transportation device and the second transportation device is at least two, and they are spaced apart along the width direction of the vehicle frame.

[0024] The beneficial effects of this utility model are as follows:

[0025] In this invention, the carrier frame of the transfer device features a rotatable design, allowing it to switch between a stowed state and a carrying state. When the platform is in a non-operational state, such as driving or turning, the carrier frame can rotate to a stowed state close to the vehicle frame, reducing the overall outward dimensions of the platform and enabling it to easily navigate narrow passages in orchards, vegetable gardens, and other similar environments. This design effectively avoids the problem of traditional fixed-structure platforms having difficulty turning due to their excessive size, significantly reducing the possibility of collisions between the platform and surrounding obstacles such as fruit trees, field ridges, and fences, ensuring the safety of the equipment and surrounding crops. It also significantly improves the platform's smoothness of movement and adaptability in complex planting environments. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0032] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0033] 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.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] 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.

[0037] like Figure 1 As shown, the novel self-propelled electric controlled harvesting and transportation platform provided by this solution includes a frame 1, which serves as the basic load-bearing structure of the entire platform, providing installation support for other components. The frame 1 is equipped with a storage platform 2 and a harvesting platform 4. The storage platform 2 is used to store fruit baskets, and the harvesting platform 4, located above the storage platform 2, is used to support workers performing harvesting operations. The frame 1 is also equipped with a transfer device 3, which can be raised and lowered. Its function is to transfer fruit baskets between the harvesting platform 4 and the storage platform 2, thereby realizing the transfer of fruits and vegetables from the harvesting location to the storage location.

[0038] The transfer device 3 includes a frame 31 and a support frame 32. The frame 31 is vertically mounted on the vehicle frame 1, and the support frame 32 is rotatably mounted on the frame 31. The transfer device 3 has a storage state and a carrying state. When in the storage state, the support frame 32 rotates and moves closer to the vehicle frame 1; when in the carrying state, the support frame 32 rotates and moves away from the vehicle frame 1 to carry the fruit basket. Here, "vertical mounting" means that the frame 31 can move vertically along the vehicle frame 1, and "rotating mounting" means that the support frame 32 can rotate about a rotation axis relative to the frame 31.

[0039] In actual operation, when it is necessary to transfer fruit baskets, the staff adjusts the transfer device 3 to the load-bearing state. At this time, the load-bearing frame 32 is away from the frame 1, which makes it easier to receive fruit baskets from the picking platform 4 or to transfer fruit baskets to the storage platform 2. When the transfer operation is completed and the platform needs to move or turn, the load-bearing frame 32 is rotated to a position close to the frame 1, so that the transfer device 3 is in the storage state, thereby reducing the overall outward size of the platform.

[0040] Furthermore, such as Figure 2 As shown, the transfer device 3 also includes a locking device 33, which is located between the frame 31 and the support frame 32 to restrict the position of the support frame 32. The locking device 33 includes a base 331, a rotating member 332, and a limiting member 333. The base 331 is mounted on the frame 31. The rotating member 332 is rotatably mounted on the rotation shaft of the support frame 32. The rotating member 332 has several helical teeth 3321 along its circumference, forming a groove 3322 between two helical teeth 3321. The limiting member 333 is rotatably mounted on the base 331 and can be inserted into the groove 3322 to lock the locking device 33. When the support frame 32 rotates to the desired position, the limiting member 333 inserts into the corresponding groove 3322, thus fixing the position of the support frame 32 and preventing accidental rotation during operation.

[0041] Optionally, the upper end face of the helical tooth 3321 is a clearance slope 3323. The locking device 33 also includes an elastic element 335 disposed between the limiting member 333 and the base 331. The elastic element 335 is used to elastically pull the limiting member 333 so that the limiting member 333 is inserted into the groove 3322. When the carrier frame 32 rotates to change the transfer device 3 from the carrying state to the storage state, the end of the limiting member 333 slides along the clearance slope 3323 and then inserts into the adjacent groove 3322. During the rotation of the carrier frame 32, the helical tooth 3321 pushes the limiting member 333 to rotate against the pulling force of the elastic element 335. When it rotates to the appropriate position, under the action of the elastic element 335, the limiting member 333 automatically inserts into the corresponding groove 3322, realizing automatic locking without additional operation.

[0042] Furthermore, the limiting member 333 is equipped with a handle 334, which can rotate the limiting member 333 to disengage it from the groove 3322. When it is necessary to adjust the position of the support frame 32, the operator can pull the handle 334 to rotate the limiting member 333, causing it to disengage from the groove 3322, thereby releasing the restriction on the support frame 32, making the operation convenient.

[0043] like Figure 1 As shown, the picking platform 4 is equipped with a transport device 41, which includes several rotating pulleys 412. The pulleys 412 are configured so that the fruit and vegetable boxes can slide on the transport device 41. Workers place fruit baskets filled with fruits and vegetables on the picking platform 4 onto the transport device 41. By rotating the pulleys 412, the fruit baskets can be easily moved on the transport device 41, facilitating their transfer to a position close to the transfer device 3.

[0044] The storage platform 2 is equipped with a transport device 21, which includes several rotating pulleys 211. The pulleys 211 are configured so that the fruit and vegetable crates can slide on the transport device 21. When the fruit crates arrive at the storage platform 2 via the transfer device 3, the rotation of the pulleys 211 can move the fruit crates to a suitable storage location on the transport device 21, reducing the handling effort of the staff.

[0045] The support frame 32 is equipped with several pulleys 321. When the fruit basket is transferred through the support frame 32, the rotation of the pulleys 321 can reduce the friction between the fruit basket and the support frame 32, making the transfer of the fruit basket smoother.

[0046] like Figure 3 As shown, the transfer device 3 also includes a telescopic component 34 and a chain 35. The telescopic component 34 is mounted on the frame 1 and is used to drive the transfer device 3 to rise and fall. One end of the chain 35 is mounted on the fixed end of the telescopic component 34, and the other end is connected to the frame 31. The telescopic end of the telescopic component 34 is equipped with a sprocket 36 for tensioning the chain 35. When the telescopic component 34 extends or retracts, the sprocket 36 drives the chain 35 to move, thereby driving the frame 31 to rise and fall, realizing the height adjustment of the transfer device 3. The telescopic component 34 can be a hydraulic cylinder, a pneumatic cylinder, etc.

[0047] The storage platform 2 is equipped with railings 5 ​​on both sides, which are rotatably mounted on the frame 1. The picking platform 4 is equipped with guardrails 6. The railings 5 ​​can block the fruit baskets on the storage platform 2 and prevent them from falling off during the platform's movement. The rotatable railings 5 ​​facilitate the loading and unloading of fruit baskets. The guardrails 6 can provide safety protection for the staff on the picking platform 4 and prevent them from falling accidentally.

[0048] A transport device 41 is installed on the picking platform 4, and includes several rotating pulleys 412. There are at least two transport devices 41, which are spaced apart along the width of the frame 1. The multiple transport devices 41 together support the fruit basket. When the fruit basket is placed on it, the force distribution is more even, and it is not easy to tilt or shake during the sliding transport through the pulleys 412, thus maintaining stability.

[0049] The second transport device 21 is installed on the storage platform 2 and includes several rotating pulleys 211. There are at least two transport devices 21, which are spaced apart along the width of the frame 1. The multiple transport devices 21 form a spaced support structure on the storage platform 2. When the fruit basket is placed on it, it can be stably supported by multiple fulcrums. During the process of moving with the platform or adjusting the position by sliding the pulleys 211, the tipping caused by uneven force at a single point can be reduced, thus ensuring the stability of the fruit basket.

[0050] This solution, through the aforementioned structural design, allows the support frame 32 of the transfer device 3 to rotate, switching between storage and carrying states. In the non-operating state, the overall size of the platform is reduced, facilitating travel and turning in narrow sections, thus solving the problem of traditional platforms being too large to pass through narrow areas. The locking device 33 ensures the stability of the support frame 32 in both operating and storage states. The cooperation between the elastic element 335 and the avoidance ramp 3323 achieves automatic locking during the rotation of the support frame 32, while the handle 334 facilitates unlocking. The inclusion of transport device one 41, transport device two 21, and pulley three 321 makes the transfer of fruit baskets more effortless and smooth. The cooperation between the telescopic element 34 and the chain 35 enables the lifting and lowering of the transfer device 3, adapting to different height transfer needs. The fence 5 and guardrail 6 respectively improve the safety of fruit basket storage and personnel. The spacing of multiple transport devices improves operational efficiency. These structures work together to enhance the practicality and reliability of the harvesting and transport platform.

[0051] 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.
