Description

Technical Field

[0001] The invention relates to the technical field of navel orange packaging and transportation, and in particular to a navel orange packaging and transportation device. Background Art

[0002] During the packaging and transportation of navel oranges, especially in small-scale operations like rural production cooperatives, manual flatbed trucks are often used for transport. The specific process involves manually stacking boxes of navel oranges layer by layer onto a flatbed truck, which is then pushed to a transport vehicle and manually loaded into the vehicle for long-distance transportation.

[0003] While this traditional method can achieve basic transport functions, in practice, operators often stack navel orange boxes in multiple layers on flatbed trucks to improve single-trip efficiency. However, navel oranges are soft and have fragile skins. The bottom box, bearing the entire static load of the upper layers, can easily suffer from concentrated pressure, leading to cell rupture and skin damage, directly impacting the commercial value and storage life of the navel oranges. Therefore, we propose a navel orange packaging and transportation device. Summary of the Invention

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figure 1 - Figure 9 The illustrated device for packing and transporting navel oranges comprises: a base 1 having rollers 2 at the bottom and a push rod 3 at one side for the operator to push and move the device; a plurality of stacked support plates 4 located on top of the base 1 for placing navel orange boxes layer by layer; a fixed frame 5 and an auxiliary frame 6 fixedly mounted on either side of the base 1, the push rod 3 fixedly mounted on the outside of the fixed frame 5, and a transfer assembly 7 disposed within the auxiliary frame 6 for transferring the navel orange boxes from the support plates 4 to a transport vehicle; The movable frame 8 is provided between the fixed frame 5 and the auxiliary frame 6, and has a vertically distributed embedded groove 9 on its inner side; the telescopic component 10 connects the support plate 4 and the movable frame 8. By adjusting the position of the embedded rod 15 in the embedded groove 9, the height spacing of each layer of the support plate 4 can be flexibly changed to adapt to navel orange boxes of different sizes; the telescopic component 10 includes a slider 12 and a first compression spring 13. The outer side of the support plate 4 is provided with a symmetrically distributed mounting groove 14. The slider 12 is slidably arranged in the mounting groove 14 and is connected to the mounting groove 14 through the first compression spring 13. The embedded rod 15 is fixed to the outer side of the slider 12, and the outer side of the slider 12 is fixed A pull rod 16 is provided, and the pull rod 16 slides in cooperation with the sliding groove provided on the side of the installation groove 14. It is worth noting that the stacking spacing of the support plates 4 is adjusted by the embedding rod 15 and the embedding grooves 9 of different heights, and each layer of support plates 4 only carries a single layer of navel orange boxes; during operation, the pull rod 16 on the outside of the support plate 4 is pulled to make the slider 12 slide along the installation groove 14 and compress the first compression spring 13. After the embedding rod 15 is disengaged from the current embedding groove 9, the support plate 4 can be freely adjusted to the target height. After releasing the pull rod 16, the first compression spring 13 rebounds and pushes the slider 12 to reset, and the embedding rod 15 is snapped into the corresponding embedding groove 9 to complete the fixation.

[0023] An auxiliary assembly 11 is provided in the fixed frame 5 and is used to drive the movable frame 8 and all the support plates 4 to rise and fall as a whole. The auxiliary assembly 11 includes a second screw 26, a gear transmission group 27 and a crank 28. The second screw 26 is rotatably connected to the inside of the fixed frame 5, the gear transmission group 27 is fixedly provided on the top of the fixed frame 5, and the crank 28 is rotatably provided on the outside of the fixed frame 5. The second screw 26 is threadedly connected to the movable frame 8 and is linked to the crank 28 through the gear transmission group 27 to achieve the lifting and lowering of the movable frame 8. The gear transmission group 27 includes a first bevel gear 29 and a second bevel gear 30 that mesh with each other and are fixed to the crank 28 and the second screw 26 respectively; The principle of the auxiliary component 11 lifting the support plate 4: the auxiliary component 11 is linked to the crank 28 through the gear transmission group 27 to drive the movable frame 8 to rise and fall as a whole. When the crank 28 rotates, the second screw 26 is driven to rotate through the engagement of the first bevel gear 29 and the second bevel gear 30. The second screw 26 is threadedly connected to the movable frame 8. When the screw rotates, the movable frame 8 moves in the vertical direction, thereby synchronously adjusting the height of all support plates 4. This design enables the device to quickly adapt to the height of the carriage of different transport vehicles and improve loading and unloading efficiency. For example, when the carriage of the transport vehicle is higher, the movable frame 8 is lifted by the crank 28 so that the support plate 4 is flush with the floor of the carriage, reducing the vertical distance of manual handling.

[0024] In addition, the transfer assembly 7 includes a transfer plate 17, a first screw 18 and a slide 19. The first screw 18 is rotatably arranged in the auxiliary frame 6 and is threadedly connected to the slide 19. The slide 19 is slidably connected to the auxiliary frame 6. The top of the first screw 18 passes through the auxiliary frame 6 and is fixed with a turning handle 20. The transfer plate 17 is rotatably connected to the slide 19 through a rotating shaft, and a retractable support block 21 is provided at the bottom of the transfer plate 17 for limiting and fixing. The support block 21 is connected to the transfer plate 17 through a fixing rod 22 and a second compression spring 23. An auxiliary block 24 is fixed to the bottom of the transfer plate 17. The fixing rod 22 passes through the auxiliary block 24 and is fixed to the auxiliary block 24. Two second compression springs 23 are provided. The two second compression springs 23 are symmetrically arranged on the outside of the fixing rod 22. One end of the second compression spring 23 is fixed to the support block 21, and the other end is fixed to the auxiliary block 24. A sink 25 is provided on the outside of the support block 21 for cooperating with the vertical surface of the auxiliary frame 6 to limit. The transfer plate 17 is provided with evenly distributed first rollers 31 on top of the rotational device. The support plate 4 is provided with a placement groove on top, and a second roller 32 is provided at the bottom of the placement groove. A placement plate 33 matching the placement groove is provided in the placement groove. The second roller 32 supports the placement plate 33. The navel orange boxes on the support plate 4 are placed on the placement plate 33. The first roller 31 and the second roller 32 cooperate to achieve smooth transfer of the navel orange boxes on the placement plate 33. Transfer assembly 7 transfers orange crates from support plate 4 to the transport vehicle using the following principles: When the device is moved to the vehicle's side, the operator turns handle 20 to rotate first screw 18, causing slide 19 to slide along auxiliary frame 6, adjusting the height of transfer plate 17. Simultaneously, transfer plate 17 rotates to a horizontal position. Support block 21 at the bottom of transfer plate 17 is linked to fixed rod 22 via second compression spring 23. Support block 21 moves toward auxiliary frame 6 under the action of second compression spring 23 and is inserted into the outside of auxiliary frame 6 through a recessed groove 25 provided on the outside of support block 21, ensuring that transfer plate 17 bears load horizontally and stably. Evenly distributed first rollers 31 are provided on the surface of transfer plate 17, cooperating with second rollers 32 in the grooves provided in support plate 4 to form a smooth conveying channel. The navel orange box is placed on the placement plate 33 of the support plate 4, and the bottom of the placement plate 33 is supported by the second roller 32. When the transfer plate 17 is aligned with the support plate 4, the operator only needs to push the navel orange box lightly to transfer the box from the support plate 4 to the transport vehicle through the rolling action of the roller, which greatly reduces manpower consumption. At the same time, the placement plate 33 moves with the navel orange box to carry the navel orange box, which can reduce the damage caused by the collision between the first roller 31 and the second roller 32 when the navel orange box passes through.

[0025] It is worth noting that a retractable shielding frame 34 is rotatably provided on the top of the placement plate 33, and a receiving groove 36 for receiving the shielding frame 34 is provided on the placement plate 33 and the support plate 4. The shielding frame 34 is rotatably connected to the support plate 4, and limiting cylinders 35 are sleeved at both ends of the shielding frame 34, which are slidably connected to the shielding frame 34. The limiting cylinder 35 can be inserted into the vertical groove provided at the end of the receiving groove 36 to fix the vertical state of the shielding frame 34; a limiting hole 37 is provided at the end of the transfer plate 17 away from the slide seat 19, and a pin shaft 38 is slidably engaged in the pin hole provided at the top of the auxiliary frame 6. Through the cooperation of the pin shaft 38 and the limiting hole 37, the transfer plate 17 is vertically stored in the auxiliary frame 6; A retractable shielding frame 34, located atop the placement plate 33, prevents the navel orange crate from accidentally slipping during transport. The shielding frame 34 is connected to the support plate 4 via a retaining cylinder 35, which inserts into a vertical slot at the end of a receiving slot 36, securing the shielding frame 34 in a vertical, fenced position. When the device needs to be stored or the transfer plate 17 is not in use, the shielding frame 34 folds into the receiving slot 36. Meanwhile, the transfer plate 17 engages with a retaining hole 37 at the top of the auxiliary frame 6 via a pin 38, allowing it to be vertically stored inside the auxiliary frame 6, avoiding the need for additional space. Furthermore, when the navel orange crate is placed on the placement plate 33, the shielding frame 34, retracted into the receiving slot 36, ensures that the support plate 4 is flush with the placement plate 33, facilitating placement of the navel orange crate on the placement plate 33. Furthermore, the enclosing structure formed by the fixing frame 5, transfer plate 17, and shielding frame 34 further enhances the stability of the crate during transport.

[0026] The implementation steps of this technical solution are as follows: S1. The operator first adjusts the spacing between the support plates 4 at each layer according to the height of the navel orange box and the transportation requirements. The specific operation is as follows: First, pull the pull rod 16 on the outside of the support plate 4 to make the slider 12 slide along the installation groove 14, compress the first compression spring 13, and drive the embedded rod 15 out of the current embedded groove 9; then, manually lift the support plate 4 to the target height and release the pull rod 16. The first compression spring 13 rebounds and pushes the slider 12 back to its original position, and the embedded rod 15 is snapped into the embedded groove 9 of the corresponding height to complete the fixation; thereafter, if the height of all support plates 4 needs to be adjusted synchronously, the crank 28 on the outside of the fixing frame 5 can be rotated. The crank 28 drives the second screw 26 to rotate through the gear transmission group 27 (the first bevel gear 29 is meshed with the second bevel gear 30), driving the movable frame 8 to rise and fall as a whole, thereby adjusting the stacking spacing of all support plates 4 to match the height of the transport vehicle compartment; S2. Place single-layer navel orange crates one by one on placement plate 33 of support plate 4, ensuring that each layer carries only a single crate to avoid stacking pressure. Flip upward the shielding frame 34 on top of placement plate 33 so that its limiting cylinder 35 is inserted into the vertical groove at the end of the receiving slot 36. Together with the transfer plate 17 stored in the fixing frame 5 and auxiliary frame 6, it forms a vertical fence to prevent the navel orange crates from sliding during transportation. The operator pushes the device with the push rod 3 and uses the bottom rollers 2 to move the device loaded with navel orange boxes to the vicinity of the transport vehicle; S3. The operator turns the handle 20 on the top of the auxiliary frame 6 to drive the first screw 18 to rotate, so that the slide 19 slides along the auxiliary frame 6 and moves the transfer plate 17 to a position flush with the bottom plate of the transport vehicle compartment; releases the limit of the transfer plate 17 and the auxiliary frame 6, and pulls out the pin shaft 38 from the limit hole 37 of the transfer plate 17, thereby extending the transfer plate 17 horizontally in the direction of the transport vehicle compartment. At the same time, the support block 21 at the bottom of the transfer plate 17 moves toward the auxiliary frame 6 under the action of the second compression spring 23, and is inserted into the outside of the auxiliary frame 6 through the sink groove 25 provided on the outside of the support block 21 to ensure that the transfer plate 17 is horizontal and stable in bearing weight; check whether the first roller 31 on the transfer plate 17 is aligned with the second roller 32 in the placement groove of the support plate 4 to ensure that a continuous and smooth conveying channel is formed; S4. The operator gently pushes the placement plate 33 on the support plate 4, and uses the rolling action of the second roller 32 to slide the placement plate 33 along the support plate 4 to the area of the first roller 31 on the transfer plate 17. The operator continues to push the navel orange box, and the rolling action of the first roller 31 smoothly transports the box to the transport vehicle compartment. No manual lifting and handling is required during the entire process, reducing the risk of fruit damage. S5. After the transfer is completed, pull out the pin 38 on the top of the auxiliary frame 6, retract the transfer plate 17 vertically around the rotation axis to the inside of the auxiliary frame 6, and then use the first screw 18 to reset the slide 19. Then, insert the pin 38 into the limiting hole 37 of the auxiliary frame 6 and the transfer plate 17 to fix the transfer plate 17 and the auxiliary frame 6; pull out the limiting cylinder 35 of the shielding frame 34 upward, withdraw it from the vertical groove, and fold the shielding frame 34 into the storage groove 36 to restore the device to a compact state; Afterwards, the crank 28 is rotated in the opposite direction to lower the height of the movable frame 8 so that the support plate 4 returns to its initial position; S6. Check whether all components have been reset, then reload the next batch of navel orange boxes and repeat the above process.

[0027] Example 2: This embodiment further explains Example 1, and the difference lies in the optimization of the roller 2; Specifically, the roller 2 can be a universal wheel to improve the smoothness of the steering process of the device.

[0028] Example 3: This embodiment further explains Example 1, and the difference lies in the optimization of the placement plate 33; Specifically, a rubber pad (not shown in the drawings) can be provided on the surface of the placement plate 33 to cushion the impact on the navel orange boxes on the placement plate 33 when the buffer device is bumpy, thereby reducing possible damage to the navel oranges during transportation to the transport vehicle through the device.
