Description

Technical Field

[0001] This invention relates to the field of cold chain storage technology for agricultural products, and in particular to an intelligent transfer and lifting conveyor device for cold chain storage of agricultural products. Background Technology

[0002] Lifting devices are needed to transport agricultural products in cold chain storage.

[0003] In existing technologies, lifting devices such as forklifts are typically used to control the lifting and lowering of agricultural products. When in use, the forklift's boom lifts the pallet, and the agricultural products are placed on the pallet. The boom lacks a locking structure for the pallet, which means that the pallet cannot be reliably secured during transportation, making it prone to shaking or displacement. This instability may not only cause agricultural products to fall off the pallet or be crushed and damaged, but also affect the safety and positioning accuracy of the transfer operation, increasing the risk of damage to agricultural products in the cold chain storage process.

[0004] Therefore, it is necessary to design an intelligent transfer and lifting conveyor system for cold chain storage of agricultural products to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an intelligent transfer and lifting conveyor device for cold chain storage of agricultural products.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An intelligent transfer and lifting conveying device for cold chain storage of agricultural products includes a lifting module and a pallet. The lifting module includes a frame, on which a transport plate is slidably mounted. A vertical plate is fixed to the bottom of the transport plate, and a fixing rod is fixed to the side of the transport plate. An installation plate is provided on one side of the transport plate, and two connecting plates are fixed to the side of the installation plate. Both connecting plates are rotatably mounted on the fixing rod. Two lifting structures are provided on the side of the installation plate, each of which includes a bracket, and each bracket is provided with a pushing component. The tray is provided with two positioning components, and the vertical plate is provided with a driving component.

[0007] As a preferred embodiment of the present invention, in the lifting structure, the bracket is fixed to the side of the mounting plate, and the bracket has two opposite openings. A movable plate is slidably disposed in each opening. The lifting structure also includes a guide rod, which is fixed to the bracket. Two guide blocks are slidably sleeved on the guide rod, and the two guide blocks are respectively fixed to the two movable plates. Each guide block is connected to the bracket by a first spring.

[0008] As a preferred embodiment of the present invention, the positioning component includes two assembly plates, both of which are fixed on a tray. Each assembly plate has a slot on its side, and the two slots are arranged facing each other.

[0009] As a preferred embodiment of the present invention, the pushing component includes a limiting rod, which is fixed on a bracket. A movable seat is slidably disposed on the limiting rod. A connecting rod is fixed to the side of the movable seat. A push plate is fixed to the end of the connecting rod away from the movable seat. Two inclined surfaces are provided on the push plate. The push plate is positioned opposite the distance between the two movable plates. The two inclined surfaces on the push plate are respectively positioned opposite the two movable plates.

[0010] As a preferred embodiment of the present invention, the driving assembly includes a cylinder and a slide rail. The cylinder is mounted on the side of the vertical plate, the slide rail is fixed to the side of the vertical plate, a slide seat is slidably sleeved on the slide rail, the telescopic end of the cylinder is connected to the slide seat, a lifting plate is fixed to the side of the slide seat, and two connecting structures are provided on the lifting plate, which are respectively connected to two movable seats.

[0011] As a preferred embodiment of the present invention, the connecting structure includes an outer cylinder and a movable rod. The outer cylinder is rotatably mounted on the side of the lifting plate. A groove is provided at the end of the outer cylinder away from the lifting plate. The movable rod is slidably disposed in the groove. One end of the movable rod extends to the outside of the groove and is rotatably connected to the movable seat. The outer cylinder and the movable rod are connected by a second spring.

[0012] As a preferred embodiment of the present invention, the groove wall is fitted to the outer surface of the movable rod.

[0013] As a preferred embodiment of the present invention, a support assembly is provided on the side of the mounting plate. The support assembly includes a horizontal plate, which is fixed to the side of the mounting plate. A vertical rod is fixed to the bottom surface of the horizontal plate. A roller is installed at the end of the vertical rod away from the horizontal plate. A fixing block is fixed on the vertical plate. A lifting block is fixed to the side of the lifting plate. An inclined surface is provided on the lifting block, and the inclined surface of the lifting block is directly opposite the roller.

[0014] As a preferred technical solution of the present invention, in the initial state, the vertical plate is in a vertical state and the fixing block is in contact with the lifting plate.

[0015] The present invention has the following beneficial effects: 1. By setting a sliding movable plate on the bracket and a positioning component with a slot on the pallet, the movable plate is automatically locked into the slot by using a cylinder to drive the push plate, thus achieving reliable locking between the bracket and the pallet. This effectively avoids the pallet from shaking or shifting in position relative to the bracket during transportation, and improves the stability and safety of agricultural products in cold chain storage and transfer operations. 2. A support assembly is provided. When the cylinder drives the movable block to move to its limit position, the lifting block lifts the roller through the inclined plane, causing the mounting plate and bracket to rotate around the fixed rod and tilt the pallet. The gravity component forces the goods to slide towards the mounting plate, thus effectively preventing agricultural products from slipping off the pallet during transportation.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Example 1: This example describes the intelligent transfer and lifting conveyor device for cold chain storage of agricultural products disclosed in this embodiment, referring to... Figure 1-8 The system includes a lifting module and a tray 8. The lifting module includes a frame 1, on which a transport plate 2 is slidably mounted. A drive module for moving the transport plate 2 is mounted on the frame 1. When the drive module is running, the transport plate 2 can move up and down along the frame 1. The specific structure and working principle of the drive module are existing technologies, and the implementation method adopts conventional means. It is not shown in the figure and will not be described in detail here. A vertical plate 21 is fixed to the bottom of the transport plate 2, and a fixing rod 22 is fixed to the side of the transport plate 2. A mounting plate 3 is provided on one side of the transport plate 2. Two connecting plates 31 are fixed to the side of the mounting plate 3. Both connecting plates 31 are rotatably mounted on the fixing rod 22. The two connecting plates 31 can rotate around the fixing rod 22, so that the mounting plate 3 can rotate around the fixing rod 22.

[0020] The mounting plate 3 has two supporting structures on its side. The supporting structure includes a bracket 41, which is fixed to the side of the mounting plate 3. The bracket 41 has two openings 42 facing each other. A movable plate 43 is slidably installed in each opening 42. The side of the movable plate 43 fits against the inner surface of the opening 42 to ensure the stability of the movable block during movement. The supporting structure also includes a guide rod 44, which is fixed to the bracket 41. Two guide blocks 45 are slidably mounted on the guide rod 44. The two guide blocks 45 are fixed to the two movable plates 43 respectively. Each guide block 45 is connected to the bracket 41 by a first spring 46. Under the elastic force of the two first springs 46, the two guide blocks 45 tend to move away from each other.

[0021] The pallet 8 is equipped with two positioning components, each consisting of two mounting plates 81. Both mounting plates 81 are fixed to the pallet 8, and each mounting plate 81 has a slot 82 on its side. The two slots 82 are positioned opposite each other. When lifting, two brackets 41 are inserted under the pallet 8. At this time, the two brackets 41 are respectively positioned between the two opposite mounting plates 81. Then, the two movable plates 43 on each bracket 41 move away from each other, so that the four movable plates 43 are respectively engaged in the four slots 82. In this case, the four movable plates 43 and the four slots 82 together fix the two brackets 41 and the pallet 8, preventing the pallet 8 from shaking on the brackets 41 and ensuring the stability of the goods during transportation.

[0022] Each bracket 41 is equipped with a pushing component for driving the two movable plates 43 to move. The pushing component includes a limiting rod 51, which is fixed to the bracket 41. A movable seat 52 is slidably mounted on the limiting rod 51. The side of the movable seat 52 is in contact with the side of the bracket 41 to ensure the stability of the movable seat 52 during movement and prevent it from shaking. A connecting rod 54 is fixed to the side of the movable seat 52. A push plate 53 is fixed to the end of the connecting rod 54 away from the movable seat 52. The push plate 53 has two inclined surfaces. The distance between the two movable plates 43 is set directly opposite to the distance between the two movable plates 43. The two inclined surfaces on the push plate 53 are respectively set directly opposite the two movable plates 43. The vertical plate 21 is equipped with a drive assembly, which includes a cylinder 71 and a slide rail 72. The cylinder 71 is installed on the side of the vertical plate 21, and the slide rail 72 is fixed to the side of the vertical plate 21. A slide seat 73 is slidably sleeved on the slide rail 72. The telescopic end of the cylinder 71 is connected to the slide seat 73. A lifting plate 74 is fixed to the side of the slide seat 73. The lifting plate 74 is equipped with two connecting structures, which are respectively connected to the two movable seats 52.

[0023] The connecting structure includes an outer cylinder 761 and a movable rod 763. The outer cylinder 761 is rotatably mounted on the side of the lifting plate 74. A groove 762 is provided at the end of the outer cylinder 761 away from the lifting plate 74. The movable rod 763 is slidably disposed in the groove 762, with one end extending to the outside of the groove 762 and rotatably connected to the movable seat 52. The outer cylinder 761 and the movable rod 763 are connected by a second spring 764. When the lifting and transporting device proposed in this invention is in use, agricultural products are placed on a pallet 8. The operator controls the frame 1 to move, causing two brackets 41 to insert under the pallet 8. For the two brackets 41, they are respectively inserted between two opposite mounting plates 81. Subsequently, the operator activates the cylinder 71. When cylinder 71 operates, it drives slide 73 to move upward. When slide 73 moves upward, it drives lifting plate 74 to move upward. When lifting plate 74 moves upward, it can push two movable seats 52 to move synchronously through two outer cylinders 761 and two movable rods 763. When movable seats 52 move, they can drive push plate 53 to move through connecting rod 54. During the movement of push plate 53, the two inclined surfaces of push plate 53 press against two movable plates 43, causing the two movable plates 43 to move away from each other. When the two movable plates 43 move away from each other, they will be locked into two slots 82 respectively. In this case, the four movable plates 43 and the four slots 82 together play a role in fixing the two brackets 41 and the pallet 8, preventing the pallet 8 from shaking on the brackets 41 and ensuring the stability of the goods during transportation.

[0024] Example 2: Based on Example 1, this example discloses an intelligent transfer and lifting conveyor device for cold chain storage of agricultural products, such as... Figure 6As shown, a support assembly is provided on the side of the mounting plate 3. The support assembly includes a horizontal plate 61, which is fixed to the side of the mounting plate 3. A vertical rod 62 is fixed to the bottom surface of the horizontal plate 61. A roller 64 is installed at the end of the vertical rod 62 away from the horizontal plate 61. A fixing block 63 is fixed on the vertical plate 21. In the initial state, the vertical plate 21 is in a vertical state. The fixing block 63 is in contact with the lifting plate 74. The fixing block 63 provides support for the vertical plate 21, so that the mounting plate 3 and the vertical rod 62 are kept in a vertical position. A lifting block 75 is fixed to the side of the lifting plate 74. An inclined surface is provided on the lifting block 75. The inclined surface of the lifting block 75 is set directly opposite the roller 64.

[0025] During the movement of the movable plate 43 driven by the cylinder 71, when the movable plate 43 reaches its limit position, the two movable seats 52 can no longer move. At this time, the extension end of the cylinder 71 remains extended. During this process, the movable rod 763 overcomes the elastic force of the second spring 764 and retracts into the outer cylinder 761. The relative sliding between the movable rod 763 and the outer cylinder 761 can avoid motion interference between the cylinder 71 and the movable seat 52. Subsequently, the lifting plate 74 continues to drive the lifting block 75 to move upward, so that the inclined surface of the lifting block 75 lifts the roller 64, thereby causing the roller 64 to drive the vertical rod 62 to rotate. When the vertical rod 62 rotates, the mounting plate 3 rotates accordingly, and the two brackets 41 and the tray 8 also rotate synchronously, forming a... Figure 6 In the state shown, under this condition, the goods on pallet 8 will slide towards the mounting plate 3 under the action of the component of gravity, which can prevent the goods from slipping off pallet 8 during transportation.

[0026] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
