Description

Technical Field

[0001] This utility model belongs to the field of transport aircraft technology, specifically relating to a monorail transport aircraft. Background Technology

[0002] Monorail conveyors are commonly used for transporting fruits and vegetables in mountainous areas. Due to the undulating terrain, fruits and vegetables placed on the conveyor tend to tilt and undulate with the machine during transport, easily leading to problems such as rolling, bumping, and falling. While the applicant's earlier application for a self-balancing rack specifically designed for monorail conveyors effectively prevents these problems, it still has shortcomings. For example, it can only accommodate a single rack, and each rack is large, making it impossible to categorize various fruits and vegetables, thus limiting transport efficiency and operational flexibility. Therefore, improvements to the existing technology are urgently needed. Summary of the Invention

[0003] The purpose of this utility model is to provide a single-track transport machine that improves the structure of the storage rack to solve the problems of the existing storage rack being unable to classify and having poor flexibility, thereby achieving the classified storage and efficient transportation of different kinds of fruits and vegetables.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0005] This utility model discloses a monorail transport machine, including a power head, several frames arranged in a straight line connected to the power head, and a guide wheel mechanism set at the bottom of the frames. Several self-balancing storage baskets are provided on the frames. Each self-balancing storage basket includes a storage basket, a rotating shaft set on both sides of the storage basket, and a support base supporting the rotating shaft and allowing the rotating shaft to rotate around its own axis. The two rotating shafts are symmetrical from left to right. The support base is installed on the frame and includes a base body, a guide block, a spring, and a limiting block. The guide block and the spring are set in the guide groove of the base body, and the spring is located below the guide block, providing upward support and buffering for the guide block. The rotating shaft of the storage basket is inserted into the guide block, and the limiting block is installed at the top of the base body, thereby closing the guide groove to form a guide space.

[0006] Compared with existing technologies, this utility model achieves classified storage of different types of fruits and vegetables by setting multiple self-balancing storage baskets on the frame. At the same time, the design of the self-balancing storage baskets can automatically maintain the balance of the storage baskets by using the rotation of the shaft in the support seat when the transport machine travels on undulating terrain, reducing the rolling and collision of fruits and vegetables, meeting diverse transportation needs, and improving transportation efficiency. The supporting and buffering effect of the spring in the support seat on the guide block, as well as the weight of the fruits, vegetables and storage baskets themselves, can effectively reduce the impact of mountain bumps on fruits and vegetables, further protecting the quality of fruits and vegetables.

[0007] The storage basket has an overall structure that is wider at the top and narrower at the bottom. Preferably, the storage basket has an inverted frustum structure.

[0008] This structural design draws inspiration from the form of traditional baskets. On the one hand, it can stably support and place regular baskets, facilitating loading and transportation; on the other hand, the storage basket itself can also be used directly as a basket, simplifying the transportation process.

[0009] The storage basket includes an upper ring, a lower ring, and several connecting rods evenly distributed around the circumference between the upper ring and the lower ring. The lower ring also has a concentric ring, and there are several supporting rods between the lower ring and the concentric ring.

[0010] The basic frame structure of the storage basket is formed by the upper ring, lower ring and connecting rod. The concentric ring and support rod further enhance the structural strength and stability of the bottom of the storage basket, making it less prone to deformation when loading fruits and vegetables. It also provides more stable support for placing baskets or directly loading fruits and vegetables.

[0011] The frame includes a mesh tray and guardrails on both sides of the mesh tray, and the support base is installed on the guardrails.

[0012] The frame adopts a structure of mesh tray and guardrail, with the support base installed on the guardrail. This not only ensures that the storage basket meets the height requirements for rotating around the axis, but also places the entire storage basket between the two guardrails, playing a role in stabilizing and protecting the fruits and vegetables. Combined with the speed adjustment device of the power head, the reasonable design of the guide wheel mechanism, and the self-balancing storage basket, the monorail transporter can better adapt to complex mountainous terrain, improving the overall performance and operational flexibility of the transporter.

[0013] The length of the guardrail is greater than the length of the mesh tray, and the difference in length between the two is greater than or equal to the space between two adjacent racks. A set of self-balancing storage baskets can be placed in this space.

[0014] This design effectively utilizes the previously unused space between racks, increasing the loading capacity of the monorail transporter.

[0015] The guide block includes an intermediate body and extensions on both sides of the intermediate body. A guide space is formed between the two extensions. The guide space matches the guide groove, so that the part of the seat body located in the guide groove is embedded in the guide space. The bottom surface of the supporting spring and the bottom surface of the intermediate body that compresses the spring in the guide groove have limiting shafts, which are inserted into the center hole of the spring.

[0016] This structural design enhances the stability and fit of the connection between the guide block and the seat; the spring is positioned by the limiting shaft to prevent it from shifting or twisting during operation, ensuring that the spring can always stably provide upward support and cushioning to the guide block.

[0017] The beneficial effects of this utility model are:

[0018] Compared with existing technologies, the monorail conveyor of this invention, by setting multiple self-balancing storage baskets on the frame, whose inverted truncated cone structure can directly serve as baskets or be adapted to traditional baskets, and with the addition of detachable dividers, allows for the classified storage of fruits and vegetables, meeting diverse transportation needs. The self-balancing storage baskets are connected to the support base via a rotating shaft, and utilize the spring buffer and the damping effect of the fruits and vegetables' own weight, combined with the shock-absorbing springs of the guide wheel mechanism, to form multiple shock absorption protections, effectively reducing the rolling, bumping, and falling of fruits and vegetables caused by transportation bumps.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0023] Please see Figures 1 to 3 This utility model provides a single-track transport machine, including a power head, several frames 1 connected in a straight line to the power head, and a guide wheel mechanism 2 set at the bottom of the frames 1. Several self-balancing storage baskets 23 are provided on the frames 1. Each self-balancing storage basket 23 includes a storage basket 3, a rotating shaft 4 set on both sides of the storage basket 3, and a support seat 5 that supports the rotating shaft 4 and allows the rotating shaft 4 to rotate around its own axis. The two rotating shafts 4 are symmetrical from left to right. The support seat 5 is installed on the frame 1 and includes a seat body 6, a guide block 7, a spring 8, and a limiting block 9. The guide block 7 and the spring 8 are set in the guide groove 10 of the seat body 6, and the spring 8 is located below the guide block 7 and has an upward support and buffering effect on the guide block 7. The rotating shaft 4 of the storage basket 3 is inserted into the guide block 7. The limiting block 9 is installed at the top of the seat body 6, thereby closing the guide groove 10 to form a guide space.

[0024] The storage basket 3 has an overall structure that is wider at the top and narrower at the bottom. Preferably, the storage basket 3 has an inverted frustum structure.

[0025] This structural design draws inspiration from the form of traditional baskets. On the one hand, it can stably support and place conventional baskets, facilitating loading and transportation; on the other hand, the storage basket 3 itself can also be used directly as a basket, simplifying the transportation process.

[0026] The storage basket 3 includes an upper ring 11, a lower ring 12, and a number of connecting rods 13 evenly distributed in a circle between the upper ring 11 and the lower ring 12. The lower ring 12 is also provided with a concentric ring 14, and there are a number of support rods 15 between the lower ring 12 and the concentric ring 14.

[0027] The basic frame structure of the storage basket 3 is formed by the upper ring 11, the lower ring 12 and the connecting rod 13. The concentric ring 14 and the support rod 15 further enhance the structural strength and stability of the bottom of the storage basket 3, making the storage basket 3 less prone to deformation when loading fruits and vegetables. It also provides more stable support for placing baskets or directly loading fruits and vegetables.

[0028] In addition, we can install dividers inside storage basket 3 (not shown in the drawing) to further enhance the categorized storage function.

[0029] The frame 1 includes a mesh tray 16 and guardrails 17 arranged on both sides of the mesh tray 16, and the support base 5 is installed on the guardrails 17.

[0030] The length of the guardrail 17 is greater than the length of the mesh tray 16, and the difference in length between the two is greater than or equal to the space between two adjacent racks 1. A set of self-balancing storage baskets 23 can be placed in this space.

[0031] This design effectively utilizes the previously unused space between racks 1, increasing the loading capacity of the monorail transporter.

[0032] The guide block 7 includes an intermediate body 18 and extensions 19 disposed on both sides of the intermediate body 18. A guide space 20 is formed between the two extensions 19. The guide space 20 matches the guide groove 10, so that the part of the seat 6 located in the guide groove 10 is embedded in the guide space 20. The bottom surface of the supporting spring 8 and the bottom surface of the intermediate body 18 that presses against the spring 8 in the guide groove 10 respectively have limiting shafts 21. The limiting shafts 21 are inserted into the central hole of the spring 8.

[0033] This structural design enhances the stability and fit of the connection between the guide block 7 and the seat 6; the spring 8 is positioned by the limiting shaft 21 to prevent the spring 8 from shifting or twisting during operation, ensuring that the spring 8 can always stably provide upward support and cushioning to the guide block 7.

[0034] The following describes the installation method and working principle of the monorail transport machine of this utility model:

[0035] I. Installation of frame and support base

[0036] Frame 1 Assembly: High-strength, lightweight steel is used to construct the mesh tray 16 and guardrails 17. The mesh tray 16 is placed horizontally, and the guardrails 17 on both sides are vertically fixed to the edges of the mesh tray 16 by welding or bolting. Ensure that the length of the guardrails 17 is 15-20 cm longer than the length of the mesh tray 16 (this length difference can be adjusted according to the actual space of the frame 1 to ensure that a set of self-balancing storage baskets 23 can be accommodated). Mounting holes are pre-drilled at the top of the guardrails 17 for subsequent fixing of the support base 5.

[0037] Installation of support base 5: Fix the base 6 to the guardrail 17 with bolts through the reserved mounting holes. Before installing the spring 8, check whether the limiting shaft 21 on the bottom surface of the guide groove 10 is intact. Of course, the limiting shaft 21 can be integrally formed with the base 6. Slide the cylindrical helical spring 8 onto the limiting shaft 21. The elastic coefficient of the spring 8 is selected according to the weight of the storage basket 3 and the full load of fruits and vegetables. Generally, a spring 8 that can provide 1.2-1.5 times the load-bearing buffer force is selected. Embed the guide block 7 (the middle body 18 with extensions 19 on both sides) into the guide groove 10 of the base 6, so that the guide space 20 and the guide groove 10 are precisely matched and fitted, ensuring that the guide block 7 can slide up and down in the guide groove 10 without obvious shaking. Finally, use screws to fix the limiting block 9 to the top of the base 6 to close the guide groove 10.

[0038] II. Installation of Self-Balancing Storage Baskets

[0039] Connection of storage basket 3: The rotating shaft 4 of the self-balancing storage basket 23 is made of smooth stainless steel (other metal materials can also be selected), with a diameter of 1.5-2 cm. Insert the rotating shaft 4 into the pre-set shaft hole 22 of the guide block 7, leaving a gap of 0.1-0.2 mm between the shaft hole 22 and the rotating shaft 4 to ensure that the rotating shaft 4 can rotate flexibly. After installation, lubricant can be applied to further reduce friction.

[0040] III. Overall Operation and Handling

[0041] Start-up and operation: Connect the power supply at the power head and start the transport machine to a suitable speed using the speed adjustment device. The guide wheels of the guide wheel mechanism 2 are in contact with the track, and the shock-absorbing springs on the wheel axles buffer the vibration from the track in real time during operation.

[0042] Self-balancing is achieved as follows: When the transport vehicle travels on undulating mountain roads, the storage basket 3 tilts due to the terrain changes. At this time, the rotating shaft 4 rotates within the guide block 7 of the support base 5, causing the storage basket 3 to automatically adjust its angle to maintain balance. The support and buffering effect of the spring 8 on the guide block 7, combined with the damping effect formed by the weight of the fruits, vegetables, and the storage basket itself, effectively reduces the swaying amplitude of the storage basket 3, preventing the fruits and vegetables from rolling or bumping.

[0043] Transport complete: Upon arrival at the destination, reduce the speed of the transport aircraft until it stops, and turn off the power to the engine head. Remove the fruits and vegetables from storage basket 3. If transport is required again, the position of the dividers (not shown in the drawings) can be readjusted or the number of storage baskets 3 can be increased or decreased according to the new transport needs.

[0044] In summary, this utility model achieves the classified storage of different types of fruits and vegetables by setting multiple self-balancing storage baskets 23 on the frame; at the same time, the design of the self-balancing storage baskets 23 can automatically keep the storage baskets 3 balanced when the transport machine travels on undulating terrain by utilizing the rotation of the shaft 4 within the support base 5, reducing the rolling and collision of fruits and vegetables, meeting diverse transportation needs, and improving transportation efficiency; the supporting and buffering effect of the spring 8 on the guide block 7 in the support base 5, as well as the weight of the fruits and vegetables and the storage baskets 3 themselves acting as dampers, can effectively reduce the impact of mountain bumps on fruits and vegetables, further protecting the quality of fruits and vegetables.
