Description

Technical Field

[0001] The present invention relates to the field of goods placement equipment, and specifically refers to a smart logistics commodity storage shelf based on an agricultural trade commodity storage center. Background Art

[0002] Smart logistics is an innovative logistics model that leverages advanced information technology, the Internet of Things, big data, and artificial intelligence to achieve intelligent operation and management of all aspects of logistics, comprehensively improving logistics efficiency, reducing costs, and optimizing service quality. In the agricultural trade sector, it can provide the fastest storage and transportation services for goods with short storage cycles and high freshness requirements.

[0003] As a crucial link in the smart logistics system, warehousing centers carry out numerous core functions, including cargo transshipment, storage, and maintenance.

DETAILED DESCRIPTION

[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. 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.

[0048] In this document, the term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0049] like Figure 1 and Figure 2 As shown, the smart logistics product storage rack for agricultural product storage centers includes a frame 1 and storage units. Frame 1 consists of four uprights and several crossbeams, forming a stable three-dimensional structure. There are several storage units, equidistantly mounted on frame 1 vertically. The crossbeams correspond to the positions of the storage units, ensuring stability without affecting the storage units while also ensuring the stability of the uprights and, consequently, the overall stability of the equipment. The storage units include a placement mechanism 2, storage boxes 3, and a refrigeration assembly 4. The placement mechanism 2 is mounted on frame 1. There are several storage boxes 3, each of which is placed on the placement mechanism 2. The storage boxes 3 are rectangular containers with open tops and contain agricultural products. The placement mechanism 2 automatically arranges the boxes 3 in an orderly fashion using their weight. The refrigeration assembly 4 is mounted on frame 1 and located at the bottom of the placement mechanism 2. It contains ice cubes or other cooling materials to cool the goods in the storage boxes 3 placed at the top of the placement mechanism 2.

[0050] refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the placement mechanism 2 includes: a mounting frame 21, an extension frame 2101, rollers 22, guide rollers 23, a rotating shaft 24, a rotating frame 25, a drive plate 26, and a guide groove 27. The mounting frame 21 serves as the basic support structure of the entire placement mechanism 2 and is mounted on the frame 1 using bolts. The mounting frame 21 is made of stainless steel to ensure that it can bear the weight pressure brought by the many subsequent components and the storage box 3. There are several rollers 22, and several rollers 22 are rotatably mounted on the mounting frame 21. Several rollers 22 are arranged horizontally. The rollers 22 are composed of a central axis and a roller body, and the roller body can rotate around the central axis. The storage box 3 is placed on the rollers 22. When the storage box 3 is placed on the rollers 22, since the rollers 22 can rotate freely, the friction force on the storage box 3 during movement is reduced, allowing the storage box 3 to slide in the horizontal direction. In this embodiment, the width of the storage box 3 is adapted to the width of the mounting frame 21 to ensure that the storage box 3 can slide smoothly therein. In addition, the surface of the roller 22 is made of polyurethane material to prevent the storage box 3 from displacement or surface damage during sliding. The extension frame 2101 is mounted on the mounting frame 21 by welding, ensuring a stable connection between the two. There are multiple guide rollers 23, each rotatably mounted on the extension frame 2101. The extension frame 2101 is tilted upward away from the mounting frame 21. When a new storage box 3 needs to be placed in the placement mechanism 2, due to the tilt angle of the extension frame 2101, the storage box 3 will slide down along the inclined surface under the action of its own weight due to the rotation of the guide roller 23, ensuring that the storage box 3 can slide accurately into the area supported by the roller 22. The newly placed storage box 3 will push the already placed storage box 3 away from the extension frame 2101, so that each storage box 3 is automatically and neatly arranged together, avoiding skew or misalignment, and realizing the function of automatically placing multiple storage boxes 3 in a neat sequence using the weight of the storage boxes 3. In addition, in this embodiment, the highest point of the guide roller 23 closest to the mounting frame 21 is higher than or equal to the highest point of the roller 22, ensuring that the storage box 3 can achieve seamless and precise connection when entering the placement area, and ensuring that the storage box 3 can smoothly transition from the guide roller 23 to the roller 22 to avoid interference. The rotating shaft 24 is rotatably mounted on the mounting frame 21. The rotating shaft 24 can flexibly rotate around its own axis. The torsion spring 28 is installed between the rotating shaft 24 and the mounting frame 21. When the rotating shaft 24 rotates, the torsion spring 28 can be deformed. When the external force is removed, the elastic force of the torsion spring 28 can reset the rotating shaft 24. The rotating frame 25 is fixedly mounted on the rotating shaft 24. When the rotating frame 25 rotates with the rotating shaft 24, there will be no relative displacement, ensuring the consistency and accuracy of the entire rotation movement. The installation position of the rotating shaft 24 and the rotating frame 25 is located on the side of the rotating frame 25 away from the extension frame 2101.The upper surface of the rotating frame 25 contacts several rollers 22. As the rotating frame 25 rotates, it lifts each roller 22, forming an inclined plane. This allows each storage box 3 to move along the inclined plane, away from the extension frame 2101, under its own weight. This ensures that the storage boxes 3 farther from the extension frame 2101 slide out of the storage mechanism 2 first, ensuring first-in, first-out order and preventing prolonged congestion. Furthermore, there's no need for handling equipment to penetrate deep into the storage mechanism 2, making the removal of goods simple and quick. A drive plate 26 is mounted on the side of the rotating frame 25 near the rotating shaft 24. The drive plate 26 is tilted upward, away from the rotating frame 25. The presence of the drive plate 26 provides a convenient control point for the operator. When the lifting forks of a forklift used to transport the goods contact the drive plate 26 from top to bottom, the drive plate 26 and the rotating frame 25 are smoothly driven to rotate. Furthermore, the tilted position of the drive plate 26 ensures smooth, directional rotation, preventing interference. There are several guide grooves 27, each defined on the inner wall of the mounting frame 21. The shaft ends of the rollers 22 are slidably mounted within these guide grooves 27. Each of the guide grooves 27 is arc-shaped and coaxial with the rotating shaft 24. This ensures that when the rotating frame 25 rotates, the shaft ends of the rollers 22 always slide along the arc-shaped guide grooves 27, preventing instability such as shaft end deviation and movement, and ensuring stable and reliable rotation of the rollers 22. The rotation of the rotating frame 25 also ensures that the rollers 22 can be stably lifted and tilted, allowing the storage boxes 3 to slide in a precisely directional manner and ensuring that the storage boxes 3 remain neatly and orderly during placement and removal.

[0051] The above-described structure is specifically used as follows: When storing goods, the handling device steadily places the storage box 3 containing the agricultural products on the guide rollers 23. Under the influence of gravity, the storage box 3 slides along the inclined guide rollers 23 toward the idlers 22. Once the storage box 3 rests on the idlers 22, it stops. Subsequently, the newly placed storage box 3 continues to slide along the guide rollers 23. Once it rests on the idlers 22, it pushes the previously placed storage box 3 toward the drive plate 26. To remove goods, the handling device presses down on the drive plate 26 from top to bottom, rotating the rotating frame 25 and deforming the torsion spring 28, which in turn rotates the idlers 22. This causes each storage box 3 to slide along the inclined surface toward the drive plate 26 and into the handling device, completing the removal process. When the handling device stops pressing down on the drive plate 26, the elastic force of the torsion spring 28 resets the rotating frame 25 and the idlers 22.

[0052] This structure can utilize the deadweight of the storage box 3 and the cooperation of the inclined guide roller 23 to realize automatic orderly placement in sequence, and can also automatically orient the mobile storage box 3 according to the storage order. When placing multiple storage boxes 3, there is no need for manual fine adjustment of the position, which greatly saves labor costs and time costs and improves the efficiency of shelving goods. It can also utilize the rotation of the rotating shaft 24 and the rotating frame 25 to complete automatic picking of goods, ensure that the first placed first picked up, and avoid long-term detention of goods without goods.

[0053] according to Figure 3 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10As shown, the refrigeration assembly 4 includes: a shell 41, a through hole 42, a chamber 43, a stopper 44, a storage box 45, a first slide 46, a second slide 4601, a guide rod 47, a movable block 48, a stopper 49, and a pull rod 410. The shell 41 is mounted on the frame 1 and is made of stainless steel, which has good strength. The chamber 43 is disposed within the shell 41. The inner wall of the chamber 43 is provided with an insulating material composed of a metal steel plate and a thermally insulating polyurethane foam bonded together to ensure that the temperature in the chamber 43 is stable and can be maintained for a long time when the chamber 43 is in a low-temperature environment. There are a plurality of through holes 42, which are arranged in an array on the upper surface of the shell 41. The function of the through holes 42 is to enable air circulation between the chamber 43 and the outside world. There are two stoppers 44, which are symmetrically mounted in the chamber 43. The storage box 45 is mounted in the chamber 43 and is located at the top of the stopper 44. The storage box 45 is restrained by a stopper 44, ensuring stable movement when the box 45 is pulled. The storage box 45 in this embodiment is a hollow container with an open top, in which ice cubes, dry ice, etc. are placed. Cold air can diffuse outward through the through hole 42, ensuring that the goods in the storage mechanism 2 remain cold and fresh. A first chute 46 and a second chute 4601 are provided on the lower surface of the storage box 45. The first chute 46 and the second chute 4601 are interconnected, and the second chute 4601 is inclined relative to the first chute 46. Two guide rods 47 are smooth metal rods to reduce friction. The two guide rods 47 are mounted in the chamber 43, and a movable block 48 is slidably mounted on the guide rods 47. The movable block 48 can slide freely along the axial direction of the guide rod 47. A stopper 49 has one end mounted on the upper surface of the movable block 48, and the other end mounted in the second chute 4601. When the moving block 48 slides on the guide rod 47, the limiting rod 49 slides within the second slide groove 4601 and the first slide groove 46 as the moving block 48 moves, thereby causing the storage box 45 to move accordingly. A pull rod 410 is mounted on the moving block 48, and the end of the pull rod 410 away from the moving block 48 extends out of the chamber 43. The operator can control the sliding of the moving block 48 on the guide rod 47 by pulling the pull rod 410.

[0054] The above structure is used as follows: Pulling the pull rod 410 causes the movable block 48 to slide along the guide rod 47, causing the stop rod 49 to move from the second slide groove 4601 toward the inclined first slide groove 46, allowing the storage box 45 to move out of the chamber 43 in the direction of the pull rod 410. After placing a coolant such as ice cubes in the storage box 45, push the pull rod 410 back to reset it. During cooling, the cold air in the storage box 45 is released through the through-holes 42 in the outer shell 41, cooling the agricultural products above.

[0055] This structure can ensure that cold air can be efficiently and evenly diffused upward through the array of through holes 42 on the outer shell 41, and accurately act on the storage box 3 of the upper placement mechanism 2, creating a suitable low-temperature environment for agricultural products; with the help of the ingenious linkage structure composed of the guide rod 47, the moving block 48, the limit rod 49 and the pull rod 410, the operator only needs to pull or push the pull rod 410 to easily control the movement of the storage box 45, so as to realize the convenient placement, removal or replacement of the refrigerant, which greatly reduces the difficulty and labor intensity of operation, saves labor costs and operation time; the limit blocks 44 symmetrically installed in the chamber 43 not only firmly support the storage box 45 to prevent it from shifting or shaking during operation or operation, thereby ensuring the stability of operation, but also protect the storage box 45 to a certain extent, avoid damage caused by accidents such as collisions, extend its service life, reduce the frequency of maintenance and replacement, and indirectly improve the efficiency of warehousing operations.

[0056] In addition, the chamber 43 is also provided with a shift rod 411, a vertical rod 412, a rotating block 413, a first connecting block 414, a second connecting block 145 and a spring 416. The shift rod 411 is installed on the lower surface of the moving block 48 and forms an organic whole with the moving block 48. The vertical rod 412 is installed in the chamber 43, and the rotating block 413 is rotatably installed on the vertical rod 412 and can rotate around the axis of the vertical rod 412. The first connecting block 414 is installed on the rotating block 413, and the second connecting block 415 is installed in the chamber 43, and the first connecting block 414 and the second connecting block 415 are respectively located on both sides of the vertical rod 412, and the two ends of the spring 416 are respectively installed on the first connecting block 414 and the second connecting block 415. When the rotating block 413 rotates, it can force the spring 416 to stretch or compress. Figure 11 4. The figure shows the position of the rotating block 413 when the spring 416 is in the natural state. The above structures together constitute a locking assembly, which is used to limit the moving block 48 to prevent the pull rod 410 from being touched by external forces and moving randomly.

[0057] The above structure is used in the following manner: when the moving block 48 moves from the second slide 4601 to the first slide 46, the lever 411 will first move the rotating block 413 and the spring 416 will be stretched. When the rotating block 413 rotates and crosses the straight line connecting the second connecting block 415 and the center point of the column 412, the pulling force of the spring 416 will be used to rotate the rotating block 413 to Figure 11 As shown in the position, when the moving block 48 continues to move, it will continue to turn the rotating block 413 and compress the spring 416 until the lever 411 is out of contact with the rotating block 413 and the rotating block 413 recovers. Figure 12 At the initial moment of movement of the moving block 48, the tension of the spring 416 can be used to prevent the moving block 48 from easily moving beyond the position of the column 412, thereby providing a certain locking protection capability.

[0058] The above specific embodiments do not limit the scope of protection of the present invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may be made based on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be included within the scope of protection of the present invention.
