Description

Technical Field

[0001] This invention relates to the field of fruit and vegetable conveying technology, and in particular to a cold storage facility for storing fruits and vegetables. Background Technology

[0002] Fruit and vegetable cold storage is a key facility in modern agricultural product cold chain logistics and warehousing systems. Its core function is to extend the shelf life of fruits and vegetables by controlling environmental parameters such as temperature and humidity inside the storage. In large cold storage, fruits and vegetables are usually stored on multi-layer shelves to make full use of space. However, this high-density storage method also brings huge challenges to the entry, exit and daily inventory of fruits and vegetables. Currently, common methods for storing and retrieving fruits and vegetables mainly rely on manual operation or simple mechanized equipment, such as forklifts and fixed lifting platforms. First, manual operation is inefficient, labor-intensive, and poses safety hazards when working at heights. Second, traditional mechanized equipment lacks flexibility, making it difficult to accurately and stably store and retrieve fruit and vegetable boxes in specific locations within dense shelving, and easily causing bumps and damage to fruits and vegetables during operation. In addition, existing equipment has limited movement dimensions, usually only able to move horizontally or vertically, and cannot directly retrieve goods from deep within the shelves, often requiring wide operating aisles, reducing the space utilization rate of the cold storage. Therefore, this invention provides a cold storage facility for storing fruits and vegetables. Summary of the Invention

[0003] The purpose of this invention is to solve the above-mentioned problems by designing a cold storage facility for storing fruits and vegetables. This solution addresses the issues of low efficiency, high labor intensity, and safety hazards associated with manual operations, especially when working at heights. Furthermore, traditional mechanized equipment lacks flexibility, making it difficult to accurately and stably retrieve fruit and vegetable boxes from specific locations within densely packed shelves, and easily causing damage to the fruits and vegetables during operation. Additionally, existing equipment has limited movement dimensions, typically only allowing horizontal or vertical movement, and cannot directly retrieve goods from deep within the shelves, often requiring wide operating aisles and reducing the space utilization rate of the cold storage facility.

A moving plate is installed on one side of the drive motor, and an electric push rod is installed on one side of the moving plate. The electric push rod is fixedly installed on one side of the upper end of the drive plate. Rotation limiters are installed on one side of each of the two moving frames, and each rotation limiter is movably fitted onto the upper end of the two guide rails. A lifter is installed at the lower end of the drive plate, with its bottom end connected to both sides of the transverse moving part.

[0005] Preferably, the rotation limiter includes two connecting rods, one end of which is connected to the side wall of the two movable frames respectively. Four sliding blocks are installed on the upper end of the two connecting rods. The four sliding blocks are movably fitted onto the upper end of the two guide rails respectively. A first limiting gear ring is installed between two sliding blocks, and a second limiting gear ring is installed between the other two sliding blocks. A drive shaft is installed on the drive end of the drive motor. The other end of the drive shaft movably passes through the center of the first limiting gear ring. A drive gear is fixedly installed on the other end of the drive shaft. The drive gear is located between the first limiting gear ring and the second limiting gear ring.

[0006] Preferably, the longitudinal mover includes a sliding frame, with both ends of the sliding frame movably fitted onto the upper ends of the two sliding rods. Two upright plates are installed at the lower end of the sliding frame, and two bearings are fixedly embedded in the upper ends of the two upright plates. A moving shaft is movably embedded in the two bearings. A transmission gear is installed at the center of the moving shaft, and the transmission gear meshes with the first limiting gear ring. Two moving wheels are installed at both ends of the moving shaft, and the two moving wheels are movably embedded in the two sliding grooves.

[0007] Preferably, the lifter includes two fixed frames, which are respectively installed on both sides of the lower end of the drive plate. Two winding shafts are fixedly installed at the lower end of the two fixed frames. A transmission shaft is installed between the shafts of the two winding shafts. A driven gear is fixedly installed at the upper end of the transmission shaft, and the driven gear meshes with the drive gear.

[0008] Preferably, the lateral mover includes a sliding plate, with both ends of the sliding plate movably embedded in the two lifting grooves. The upper sides of the sliding plate are connected to the two winding shafts via ropes. A linear module is installed on the upper wall of the sliding plate, and the driving end of the linear module is connected to an installation shaft. A limit plate is fixedly installed on the lower side wall of the installation shaft, and a rotary motor is installed on the lower wall of the installation shaft. A connecting frame is movably fitted on the outside of the limit plate, with the lower end of the connecting frame located outside the rotary motor.

[0014] A cold storage facility for storing fruits and vegetables, manufactured using the technical solution of this invention, can precisely control the rotating extraction rack at the end through the coordinated work of the longitudinal mover, the lateral mover, and the drive lifting module. This allows for movement in three dimensions—front-to-back, left-to-right, and up-down—within the cold storage rack space, completely replacing manual labor and achieving automated storage and retrieval. The lifter controls the lateral mover by using a winding shaft to raise or lower the rope, resulting in smooth movements that effectively prevent mechanical damage to fruits and vegetables caused by shaking or collisions during handling. The integrated drive motor, transmission mechanism, and lifting mechanism create a compact structure, requiring less space within the rack aisles and allowing for denser rack arrangements, thus significantly improving the overall storage space utilization of the cold storage facility. Furthermore, the rotating motor drives the lifting rack and double-headed bracket to rotate at a certain angle, lifting the goods without requiring a large operating space for forklifts or other equipment, making it suitable for high-density racking systems. The engagement of the first and second limit gear rings in the rotation limiter with the drive gear not only reliably transmits the power of the drive motor to the longitudinal mover and the lifter, but also locks the longitudinal mover and the lifter as they move, ensuring the accuracy and reliability of power transmission.

[0022] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-6 As shown, a cold storage facility is used for storing fruits and vegetables.

[0023] Example: A cold storage for storing fruits and vegetables includes two longitudinal beams 1. Each longitudinal beam 1 has a sliding groove 2 on its side wall. Two sliding rods 3 are installed on the upper end of the side wall of the two longitudinal beams 1. A longitudinal mover is movably fitted on the upper end of the two sliding rods 3. The two ends of the longitudinal mover are respectively movably embedded in the two sliding grooves 2. Two lifting grooves 38 are installed on both sides of the lower end of the longitudinal mover. A transverse mover is movably embedded in the two lifting grooves 38. A drive lifting module is installed between the transverse mover and the longitudinal mover. A rotating extraction frame is installed at the lower end of the transverse mover. When storing fruits and vegetables, staff first install two longitudinal beams 1 on the upper walls of the designated cold storage room according to preservation requirements. The overall length of the longitudinal beams 1 is then cut or spliced ​​according to the specifications of the cold storage room. Next, the specifications of the longitudinal and transverse movers are adjusted according to the width of the cold storage room, and then assembled. The two ends of the longitudinal mover are then embedded into two sliding grooves 2 and movably fitted onto the upper ends of two sliding rods 3. The two sliding rods 3 ensure the overall stability of the longitudinal mover's movement. Then, the two ends of the transverse mover are embedded into two lifting grooves 38 and connected to the longitudinal mover via a drive lifting module. Finally, a rotating extraction rack is installed. When storing fruits and vegetables, the longitudinal mover is first driven by the drive lifting module to move to the outer fruit and vegetable placement position. The height of the transverse mover is then adjusted by the drive lifting module. Finally, the rotating extraction rack supports and places the fruits and vegetables. Through the cooperation of the drive lifting module, the longitudinal mover, and the transverse mover, the fruits and vegetables are hoisted and moved to the designated position for stable storage in the cold storage room.

[0024] The drive lifting module includes a drive plate 4, with both ends of the drive plate 4 fixedly connected to the lower sides of the longitudinal locator wall. An operating groove 5 is provided at the center of the drive plate 4. Two guide rails 6 are installed on both sides of the upper end of the drive plate 4, located on both sides of the upper end of the operating groove 5. A drive motor 7 is movably embedded in one side of the operating groove 5. Two moving frames 8 are installed on the outer walls of both sides of the drive motor 7, and the two moving frames 8 are movably fitted onto the upper ends of the two guide rails 6. A moving plate 9 is installed on one side of the drive motor 7, and an electric push rod 10 is installed on one side of the moving plate 9. The electric push rod 10 is fixedly installed on one side of the upper end of the drive plate 4. A rotation limiter is installed on one side of the two moving frames 8, and the two sides of the rotation limiter are movably fitted onto the upper ends of the two guide rails 6. A lifter is installed at the lower end of the drive plate 4, and the bottom end of the lifter is connected to both sides of the transverse locator.

[0025] When driving the longitudinal mover and the lifter, the operator first operates the electric push rod 10 on the upper end of the drive plate 4 according to the driving requirements. The electric push rod 10 changes the position of the drive motor 7, the two moving frames 8, and the rotation limiter on the upper end of the operating groove 5 and the two guide rails 6. When the longitudinal mover needs to be driven, the electric push rod 10 makes the drive gear 16 mesh with the transmission gear 21 of the longitudinal mover, so that the drive motor 7 can drive the longitudinal mover. At the same time, the rotation limiter located on one side of the moving frame 8 meshes with the lifter to limit the rotation of the lifter. When the longitudinal mover moves to the designated position, the electric push rod 10 works in the opposite direction to make the drive gear 16 mesh with the lifter and the rotation limiter limits the rotation of the longitudinal mover to position the longitudinal position. Then, the drive motor 7 cooperates with the lifter to lift the transverse mover and the rotating extraction frame as a whole. Then, it cooperates with the longitudinal mover again to move the fruits and vegetables to the designated position.

[0026] In the specific implementation process, the rotation limiter includes two connecting rods 11. One end of each connecting rod 11 is connected to the side wall of the two movable frames 8. Four sliding blocks 12 are installed on the upper end of the two connecting rods 11. The four sliding blocks 12 are movably fitted onto the upper end of the two guide rails 6. A first limiting gear ring 13 is installed between two sliding blocks 12, and a second limiting gear ring 14 is installed between the other two sliding blocks 12. A drive shaft 15 is installed on the drive end of the drive motor 7. The other end of the drive shaft 15 movably passes through the center of the first limiting gear ring 13. A drive gear 16 is fixedly installed on the other end of the drive shaft 15. The drive gear 16 is located between the first limiting gear ring 13 and the second limiting gear ring 14.

[0027] When the longitudinal extractor is driven, it moves along the moving frame 8 via two connecting rods 11 and four sliding blocks 12. When the drive gear 16 meshes with the transmission gear 21 of the longitudinal moving frame 8, the second limiting gear ring 14 located on the right side of the drive gear 16 meshes with the lifter to limit the rotation of the lifter. Then, the drive motor 7 cooperates with the drive shaft 15 to drive the drive gear 16 and mesh with the transmission gear 21 inside the longitudinal extractor to drive the longitudinal mover and change the position of the longitudinal mover between the two longitudinal directions. When the drive gear 16 meshes with the lifter, the first limiting gear ring 13 located on the other side of the drive gear 16 meshes with the longitudinal mover to limit the rotation of the longitudinal mover. At the same time, the drive gear 16 cooperates with the lifter to drive the lifter.

[0028] In the specific implementation process, the longitudinal mover includes a sliding frame 17, with both ends of the sliding frame 17 movably fitted onto the upper ends of two sliding rods 3. Two upright plates 18 are installed at the lower end of the sliding frame 17. Two bearings 19 are fixedly embedded in the upper ends of the two upright plates 18. A moving shaft 20 is movably embedded in the two bearings 19. A transmission gear 21 is installed at the center of the moving shaft 20. The transmission gear 21 meshes with the first limiting gear ring 13. Two moving wheels 22 are installed at both ends of the moving shaft 20. The two moving wheels 22 are movably embedded in the two sliding grooves 2.

[0029] When moving the fruits and vegetables vertically, the drive gear 16 in the drive lifting module meshes with the transmission gear 21 at the upper end of the moving shaft 20. As the transmission gear 21 rotates, the moving shaft 20 rotates at a constant speed in the two bearings 19. At the same time, the two moving wheels 22 located at both ends of the moving shaft 20 roll in the two sliding grooves 2, which can change the overall position of the sliding frame 17 and the two upright plates 18. Through the cooperation of the sliding frame 17 and the two sliding rods 3, the overall movement stability of the sliding frame 17 and the two upright plates 18 can be fully guaranteed.

[0030] In the specific implementation process, the lifting device includes two fixed frames 23, which are respectively installed on both sides of the lower end of the drive plate 4. Two winding shafts 24 are fixedly installed at the lower end of the two fixed frames 23. A transmission shaft 25 is installed between the shafts of the two winding shafts 24. A driven gear 26 is fixedly installed at the upper end of the transmission shaft 25. The driven gear 26 meshes with the drive gear 16.

[0031] When adjusting the height of the lateral mover, the two take-up shafts 24 are connected to the upper sides of the lateral mover by ropes. Then, the drive lifting module is driven to work, so that its drive gear 16 meshes with the driven gear 26 at the upper end of the transmission shaft 25. By having the driven gear 26 follow the rotation of the drive lifting module, the two take-up shafts 24 can be driven synchronously to lift the lateral mover as a whole.

[0032] In the specific implementation process, the lateral mover includes a sliding plate 27, with both ends of the sliding plate 27 being movably embedded in two lifting grooves 38. The upper sides of the sliding plate 27 are connected to two winding shafts 24 by ropes. A linear module 28 is installed on the upper wall of the sliding plate 27. The driving end of the linear module 28 is connected to a mounting shaft 29. A limit plate 30 is fixedly installed on the lower side wall of the mounting shaft 29. A rotary motor 31 is installed on the lower wall of the mounting shaft 29. A connecting frame 32 is movably fitted on the outside of the limit plate 30. The lower end of the connecting frame 32 is located outside the rotary motor 31. A lifting frame is installed at the bottom of the connecting frame 32.

[0033] When extracting and moving fruits and vegetables, the lifting module is first connected to the sliding plate 27 to adjust the height of the sliding plate 27 within the two lifting grooves 38. Then, the linear module 28 at the upper end of the sliding plate 27 is driven to work, changing the lateral position of the mounting shaft 29 until one side of the lifting frame is embedded into the side of the fruit and vegetable tray. Then, the sliding plate 27 is lifted by driving the lifting module, and the position of the lifting frame and the fruit and vegetable tray is changed by the operation of the linear module 28. According to different spaces and placement angles, the rotary motor 31 at the lower end of the mounting shaft 29 is driven to change the angle of the connecting frame 32 within the limiting plate 30, thereby adjusting the overall angle of the lifting frame and the fruit and vegetable tray. The limiting plate 30 enables the movable connection between the lifting frame and the mounting shaft 29, ensuring the lifting effect while the lifting frame can rotate stably with the rotary motor 31.

[0034] In the specific implementation process, the lifting frame includes a lifting plate 33. The four corners of the upper end of the lifting plate 33 are connected to the lower end of the connecting frame 32. The center of the upper wall of the lifting plate 33 is connected to the drive end of the rotary motor 31. A double-headed bracket 34 is installed at the lower end of the lifting plate 33.

[0035] When supporting and hoisting fruit and vegetable pallets, the staff first changes the position of the longitudinal and lateral movers. Then, one side of the double-headed bracket 34 at the lower end of the lifting plate 33 is inserted under the fruit and vegetable pallet. The lateral mover is then raised and lowered by the lifting device. With the connection of the lifting plate 33, the double-headed bracket 34 and the fruit and vegetable pallet can be hoisted as a whole. Furthermore, with the connection between the lifting plate 33 and the rotary motor 31, the angle of the lifting plate 33 and the double-headed bracket 34 can be adjusted to meet the multi-angle placement operation of the fruit and vegetable pallet.

[0036] In the specific implementation process, an auxiliary frame 35 is installed at the connection between the mounting shaft 29 and the drive end of the linear module 28.

[0037] The auxiliary frame 35 effectively ensures the connection strength between the mounting shaft 29 and the drive end of the linear module 28, preventing shaking when multiple fruit and vegetable pallets are moved and ensuring the overall transportation stability of the fruit and vegetable pallets.

[0038] In the specific implementation process, the sliding groove 2 is a concave sliding groove 2, and the bottom ends of the two moving wheels 22 are in contact with the inner lower wall of the sliding groove 2.

[0039] The concave sliding groove 2 guides the movement wheel 22 to ensure the overall rolling effect of the movement wheel 22.

[0040] In the specific implementation process, two lifting frames 36 are installed at the connection position between the sliding plate 27 and the two winding shafts 24.

[0041] The lifting frame 36 effectively ensures the connection strength between the sliding plate 27 and the rope inside the winding shaft 24, thereby ensuring the lifting stability of the lifting device on the sliding plate 27.

[0042] In the specific implementation process, two sliding sleeves 37 are installed at the connection position between the sliding frame 17 and the two sliding rods 3.

[0043] The two sliding sleeves 37 and the two sliding rods 3 are designed to work together to ensure the smooth movement of the sliding frame 17.

[0044] The above technical solutions only embody the preferred technical solutions of the present invention. Any modifications that may be made by those skilled in the art to certain parts thereof embody the principles of the present invention and fall within the protection scope of the present invention.
