Description

Technical Field

[0001] This utility model belongs to the field of greenhouse vegetable and fruit transportation technology, and specifically relates to watermelon transportation equipment based on greenhouse cultivation. Background Technology

[0002] Currently, the rise of high-standard watermelon greenhouses has driven a leap in both watermelon variety improvement and unit yield. Since watermelons in greenhouses are generally grown on raised beds, and to increase yield, only enough space for a single person to walk between adjacent beds is left; therefore, there are two common methods for transporting watermelons out of the greenhouse during the harvest season. One method is to stack watermelons in baskets, with two farmers working together to lift them out of the greenhouse. However, this purely manual method is not only inconvenient to walk in the greenhouse but also very labor-intensive. The other method is to use a wheelbarrow to transport the baskets full of watermelons out of the greenhouse. However, existing wheelbarrows have a high center of gravity after placing the baskets, making it easy for watermelons to roll out of the baskets during transport. Furthermore, existing wheelbarrows generally require ropes to secure the baskets, which is not a quick fix and affects transport efficiency. Utility Model Content

[0003] The purpose of this utility model is to overcome at least one of the aforementioned problems in the existing technology and to provide a watermelon transfer device based on greenhouse cultivation. The specific technical solution is as follows: This utility model provides a watermelon transport device based on greenhouse cultivation, including a frame with a "U"-shaped structure. A front wheel frame is horizontally welded to the front end of the frame, and a wheel is rolled below the middle of the end face of the front wheel frame. Handrails are symmetrically welded to the rear end of the frame along its long axis. A fixed clamp with an arc-shaped structure is fixedly suspended directly below the front part of the frame. A movable clamp with an arc-shaped structure is movably suspended on the side of the frame opposite to the fixed clamp. The movable clamp can slide horizontally along the long side of the frame. The ring-shaped clamp structure formed by the movable clamp and the fixed clamp can clamp a round basket used to hold watermelons, and the movable clamp is locked in position after clamping by a top component set in the rear part of the frame.

[0004] As a preferred technical solution of this utility model, the two ends of the fixed clamp are respectively connected to the corresponding long side of the frame by a suspension rod that is adapted to it and is L-shaped.

[0005] As a preferred technical solution of this utility model, the middle part of the outer arc surface of the fixed clamp is connected to the short side of the front end of the frame by a two-braced suspension rod that is adapted to it and is L-shaped.

[0006] As a preferred technical solution of this utility model, the sliding sleeves at both ends of the moving clamp are respectively axially slidingly fitted with the corresponding long side of the frame, and are connected by a three-suspension suspension rod that is adapted to it and is L-shaped.

[0007] As a preferred technical solution of this utility model, a push rod is horizontally arranged in the rear part of the frame along its short side direction. The two ends of the push rod are respectively radially and vertically connected to the sliding sleeves that are axially slidingly fitted on the corresponding long side of the frame. The middle part of the outer arc surface of the moving clamp is connected to the push rod by a four-suspension suspension rod that is adapted to it and is L-shaped.

[0008] As a preferred embodiment of this utility model, the top positioning assembly includes a top rod arranged along the long side of the frame. The rear end of the top rod is pivotally connected to a U-shaped seat fixed above the middle of the short side of the rear end of the frame, and the top rod can rotate around the U-shaped seat in a vertical plane. A locking groove is fixed above the middle of the push rod, and the locking groove is open towards the rear end of the frame. The front end of the top rod can rotate into the locking groove that matches the movable clamp after it is clamped by the circular basket to achieve the top positioning of the movable clamp.

[0009] As a preferred technical solution of this utility model, the front wheel frame and the short side of the front end of the frame form an isosceles trapezoidal frame structure, and a support rod is longitudinally fixed to the lower part of the middle of the end face of the front wheel frame, and the wheel is rotatably connected between the two support rods.

[0010] As a preferred technical solution of this utility model, the handrail is an inverted L-shaped structure, which is fixedly welded to the end face of the corresponding long side of the frame, and the bottom end of the vertical part of the handrail is flush with the bottom edge of the wheel.

[0011] As a preferred embodiment of this utility model, the horizontal end of the handrail is axially fitted with an anti-slip sleeve.

[0012] As a preferred technical solution of this utility model, the outer edge of the opening of the round basket is integrally fixed with an annular flange.

[0013] The beneficial effects of this utility model are: 1. This utility model enables rapid fixing and releasing of round baskets, improving transfer efficiency. Through a ring-shaped clamping structure formed by a fixed clamp and a movable clamp, the round basket can be quickly fitted onto the fixed clamp. Subsequently, the movable clamp slides laterally along the frame, working together with the fixed clamp to hold the portion of the round basket near its opening. A top-positioning component is located at the rear of the frame, allowing for quick locking of the position after the movable clamp has engaged, eliminating the need for additional binding tools such as ropes. This design simplifies the fixing process of round baskets, avoiding the cumbersome binding required by existing wheelbarrows, thus shortening loading and unloading time. It is suitable for high-frequency transfer operations during the watermelon harvesting season, effectively improving overall transfer efficiency.

[0014] 2. This utility model lowers the center of gravity of the equipment, enhances transport stability, and prevents watermelons from rolling off. Because the fixed and movable clamps hold the round basket near its opening, the basket's installation position on the frame is relatively low, significantly lowering the overall center of gravity of the entire equipment. Combined with the wheels positioned below the front of the frame and the frame's own "U"-shaped stabilizing structure, the equipment is less prone to tilting or swaying during transport, reducing the risk of watermelons rolling or tipping over due to a high center of gravity, thus ensuring the integrity of the watermelons and safe transport.

[0015] 3. This utility model improves the convenience and comfort of manual handling, reducing labor intensity. The symmetrical handrails welded to the rear of the frame provide melon farmers with ergonomic push-pull fulcrums, facilitating the operation of the wheelbarrow between narrow melon rows. Compared to purely manual carrying, the wheelbarrow design reduces the physical exertion of melon farmers and avoids the inconvenience of two people carrying baskets in confined spaces. The quick-locking top component further simplifies operation, allowing melon farmers to easily fix and transfer round baskets, effectively alleviating labor intensity. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model. Example

[0019] To address the technical problems in the background section, the following watermelon transfer equipment based on greenhouse cultivation is provided: Combination Figures 1-4As shown, the watermelon transfer equipment based on greenhouse cultivation includes a frame 1 with a "U"-shaped structure. A front wheel frame 11 is horizontally welded to the front end of the frame 1, and a wheel 2 is rolled below the middle of the end face of the front wheel frame 11. A handrail 12 is symmetrically welded to the rear end of the frame 1 along its long axis. A fixed clamp 3 with an arc-shaped structure is fixedly suspended directly below the front part of the frame 1. A movable clamp 4 with an arc-shaped structure is movably suspended on the side of the frame 1 that is horizontally opposite to the fixed clamp 3. The movable clamp 4 can slide laterally along the long side of the frame 1. The ring-shaped clamp structure formed by the movable clamp 4 and the fixed clamp 3 can clamp the round basket 7 used to hold watermelons. The movable clamp 4 is locked in position after clamping by a top component 6 set in the rear part of the frame 1.

[0020] In the above technical solution, the watermelon transfer equipment can quickly fix and release the round basket 7, improving transfer efficiency. Through the annular clamping structure formed by the fixed clamp 3 and the movable clamp 4, the round basket 7 can be quickly fitted into the fixed clamp 3. Then, the movable clamp 4 slides laterally along the frame 1, together with the fixed clamp 3, clamping the part of the round basket 7 near the opening. The top positioning component 6 is located in the rear of the frame 1, which can quickly lock the position of the movable clamp 4 after clamping, without the need for additional binding tools such as ropes. This design simplifies the fixing steps of the round basket 7, avoids the cumbersome binding problem required by existing wheelbarrows, thereby shortening the loading and unloading time. It is suitable for high-frequency transfer operations during the watermelon harvesting season and effectively improves the overall transfer efficiency.

[0021] This watermelon transfer device lowers the center of gravity, enhancing transfer stability and preventing watermelons from rolling off. Because the fixed clamp 3 and movable clamp 4 hold the round basket 7 near its opening, the basket 7 is mounted relatively low on the frame 1, significantly lowering the overall center of gravity of the device. Combined with the wheels 2 positioned below the front end of the frame 1 and the frame 1's own "U"-shaped stabilizing structure, the device is less prone to tilting or swaying during transfer, reducing the risk of watermelons rolling or tipping over due to a high center of gravity, thus ensuring the integrity of the watermelons and safe transportation.

[0022] This watermelon transport equipment improves the convenience and comfort of manual handling, reducing labor intensity. The symmetrical handrails 12 welded to the rear of the frame 1 provide farmers with ergonomically designed push-pull fulcrums, facilitating the operation of the wheelbarrow between narrow watermelon rows. Compared to manual lifting, the wheelbarrow design reduces the physical exertion of farmers and avoids the inconvenience of two people carrying baskets in confined spaces. The quick-locking top component 6 further simplifies operation, allowing farmers to easily secure and transport the round baskets 7, effectively alleviating labor intensity.

[0023] like Figure 1 and Figure 2As shown, the two ends of the fixed clamp 3 are respectively connected to the corresponding long sides of the frame 1 by L-shaped hangers 31. The middle part of the outer arc surface of the fixed clamp 3 is connected to the short side of the front end of the frame 1 by L-shaped hangers 32.

[0024] In the above technical solution, the fixed clamp 3 is connected to the frame 1 through multiple L-shaped hangers, forming a stable triangular support structure. This design effectively distributes and transfers the weight of the round basket 7 to the frame 1 through the hangers, avoiding stress concentration, ensuring the rigidity and durability of the entire front structure under load, and preventing the round basket 7 from loosening due to deformation under stress.

[0025] like Figure 1 and Figure 2 As shown, the two ends of the moving clamp 4 are respectively axially slidingly fitted with the sliding sleeve 42 on the corresponding long side of the frame 1, and are connected by a matching L-shaped hanger 41.

[0026] like Figure 1 and Figure 2 As shown, a push rod 5 is horizontally arranged in the rear part of the inner side of the frame 1 along its short side. The two ends of the push rod 5 are radially and vertically connected to the sliding sleeves 51 that are axially slidingly fitted on the corresponding long side of the frame 1. The middle part of the outer arc surface of the moving clamp 4 is suspended and connected to the push rod 5 by a matching L-shaped hanger 52.

[0027] In the above technical solution, the movable clamp 4 is connected to the long side of the frame 1 through the sliding sleeves 42 at both ends and the hanging rod 41, realizing lateral sliding along the frame 1. A synchronous drive mechanism is formed by a horizontally placed push rod 5, the sliding sleeves 51 at both ends, and the hanging rod 52 connecting the push rod 5 and the middle of the movable clamp 4. The operator only needs to push or pull the push rod 5 at the rear of the frame 1 to synchronously control the movement of the movable clamp 4, realizing a smooth operation of clamping and releasing with one hand, and improving the efficiency of fixing and releasing the round basket 7.

[0028] like Figures 1-4 As shown, the top positioning assembly 6 includes a top rod 61 arranged along the long side of the frame 1. The rear end of the top rod 61 is pivotally connected to a U-shaped seat 62 fixed above the middle of the short side of the rear end of the frame 1, and the top rod 61 can rotate around the U-shaped seat 62 in the vertical plane. A locking groove 63 is fixed above the middle of the push rod 5, and the locking groove 63 is opened towards the rear end of the frame 1. The front end of the top rod 61 can rotate into the locking groove 63 after the movable clamp 4 and the round basket 7 are clamped, thereby positioning the movable clamp 4.

[0029] In the above technical solution, the top rod 61 of the top component 6 can rotate in the vertical plane around the U-shaped seat 62. When the movable clamp 4 moves to the position of clamping the round basket 7 via the push rod 5, the front end of the top rod 61 only needs to be rotated downwards and embedded into the locking groove 63 fixed on the push rod 5. By the top rod 61 abutting against the locking groove 63, the tendency of the push rod 5 and the entire movable clamp 4 connected to it to retract backwards is effectively locked, thus realizing a mechanical self-locking that can be completed quickly without ropes. This locking method is not only fast, but also more reliable than traditional binding, effectively preventing the round basket 7 from loosening due to vibration during transportation.

[0030] like Figures 1-3 As shown, the front wheel frame 11 and the short side of the front end of the frame 1 form an isosceles trapezoidal frame structure. Support rods 21 are longitudinally fixed to each other below the middle of the end face of the front wheel frame 11, and the wheel 2 is rotatably connected between the two support rods 21.

[0031] In the above technical solution, the front wheel frame 11 and the front end of the frame 1 form an isosceles trapezoidal frame, and the wheels 2 are mounted on the longitudinally arranged support rods 21 below, thus forming a stable load-bearing and walking foundation. This structure can withstand the pressure of a fully loaded round basket 7 and the bumps during travel, ensuring that the equipment will not become unstable due to structural deformation and improving the overall mechanical strength.

[0032] like Figure 1 , Figure 3 and Figure 4 As shown, the handrail 12 has an inverted L-shaped structure, which is fixedly welded to the end face of the corresponding long side of the frame 1, and the bottom end of the vertical part of the handrail 12 is flush with the bottom edge of the wheel 2.

[0033] like Figures 1-4 As shown, the horizontal end of the handrail 12 is axially fitted with an anti-slip sleeve 121.

[0034] In the above technical solution, the bottom of the vertical part of the handrail 12 is flush with the bottom edge of the wheel 2, which allows the equipment to form a stable three-point support together with the wheel 2 when parked. Whether loading, unloading, or pausing midway, the equipment can stand firmly on the ground without tilting forward or backward, ensuring operational safety.

[0035] The anti-slip sleeve 121, which is fitted onto the horizontal end of the handrail 12, increases the friction of the operator's hand. Even when the palms are sweaty or wet, it ensures a firm and comfortable grip during push-pull operation, preventing slippage and improving ergonomics and operational safety.

[0036] like Figure 3 and Figure 4 As shown, the outer edge of the opening of the round basket 7 is integrally fixed with an annular flange 71.

[0037] In the above technical solution, an annular flange 71 is integrally provided on the outer edge of the opening of the round basket 7. When the fixed clamp 3 and the movable clamp 4 are clamped at the opening of the basket, this annular flange 71 plays a physical limiting role. Even if the vehicle experiences significant bumps on rough roads, the round basket 7 cannot easily detach from the clamping structure upwards or outwards. Together with the clamping force, it forms a double safety measure to prevent the round basket 7 from accidentally slipping, thus significantly improving the safety of the transportation process.

[0038] Working principle and usage process of this utility model: In use, the operator first manually pulls the push rod 5 backward. The push rod 5 slides on the long side of the frame 1 through the sliding sleeves 51 at both ends. At the same time, the moving clamp 4 moves backward along the frame via the L-shaped hanging rod 52, thereby opening the space between the fixed clamp 3 and the moving clamp 4. Then, the round basket 7 containing watermelons is placed into this space, so that the opening of the basket, especially below the annular flange (71), is securely fitted and supported in the fixed clamp 3.

[0039] Next comes the clamping and locking stage: the operator pushes the push rod 5 forward. The push rod 5, through the lifting rod 4 52, pushes the movable clamp 4 to slide laterally along the frame, causing it to close together with the fixed clamp 3, forming a ring-shaped clamp structure that firmly clamps the round basket 7. Subsequently, the operator rotates the top rod 61 of the top positioning assembly 6 downward, so that its front end is embedded in the locking groove 63 fixed in the middle of the push rod 5, preventing the push rod 5 and the entire movable clamp 4 connected to it from moving backward, thus achieving a fast and reliable mechanical locking of the position.

[0040] Finally, the transfer and unloading stage: The operator holds the handlebar 12 and lifts the rear end of the frame so that the wheels 2 touch the ground, allowing for smooth transfer between the melon rows. Upon arrival at the destination, the equipment is placed stably, the top rod 61 is rotated upwards to release the lock, and the push rod 5 is pulled backwards to open the clamp structure and remove the round basket 7.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
