[0002] Food refers to all kinds of finished products, raw materials, and items that are traditionally both food and Chinese medicinal materials for human consumption or drinking. From the perspective of food hygiene legislation and management, food in a broad sense is the same concept as agricultural products, food additives, and related items.

[0003] When transporting boxed food, forklifts or other equipment are used to move the stacked food from the factory to the vicinity of the truck bed. Then, ground staff manually lift and move the food, while staff inside the truck bed need to retrieve the boxes. Because the transport vehicles are generally large and the truck bed is high, staff inside the truck bed need to bend over repeatedly when retrieving food, which can easily cause fatigue and back injuries.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution:

[0023] A loading device for food logistics transportation includes a base 1. An adjusting seat 2 is vertically and movably mounted on the base 1 via an adjusting mechanism. Two cargo boxes 3 are mounted on the top of the adjusting seat 2 via a switching mechanism. The switching mechanism includes a first motor 4, a bracket 5, a main shaft 6, and connecting arms 7. The two brackets 5 are vertically and fixedly mounted on the top of the adjusting seat 2. The main shaft 6 is rotatably connected between the two brackets 5. The first motor 4 is fixedly mounted on the surface of one of the brackets 5, and the output end of the first motor 4 is connected to one end of the main shaft 6. The center parts of the two connecting arms 7 are fixedly mounted on the surface of the main shaft 6. The side of one cargo box 3 is rotatably connected to one end of the two connecting arms 7, and the side of the other cargo box 3 is rotatably connected to the other end of the two connecting arms 7.

[0024] Please see Figures 1-3The first motor 4 is started, which drives the main shaft 6 to rotate. When the main shaft 6 rotates, it drives the connecting arm 7 to rotate. When the connecting arm 7 rotates, its far end drives the cargo box 3 to rotate synchronously. At this time, the cargo box 3 remains horizontal due to its own weight and the hinged state between the connecting arm 7 and the cargo box 3. Therefore, the staff can lift the cargo by placing it on the cargo box 3, so that the staff in the carriage can load the cargo. After loading is completed, the first motor 4 is reversed, so that the empty cargo box 3 is lowered and the other cargo box 3 filled with cargo is raised, so that the staff in the carriage can continue to load cargo. After the empty cargo box 3 is lowered, the staff on the ground can continue to fill the cargo box 3 with cargo.

[0025] The adjustment mechanism consists of four lifting units symmetrically arranged between the base 1 and the adjustment seat 2. Each lifting unit includes a second motor 8, a threaded rod 9, a traction block 10, and a support rod 11. The second motor 8 is fixedly installed on the surface of the base 1, the threaded rod 9 is rotatably connected to the surface of the base 1, the output end of the second motor 8 is connected to one end of the threaded rod 9, the traction block 10 is threadedly connected to the surface of the threaded rod 9, the top of the traction block 10 is hinged to the bottom of the support rod 11, and the top of the support rod 11 is hinged to the bottom of the adjustment seat 2.

[0026] Please see Figures 1-3 The second motor 8 is started, which drives the threaded rod 9 to rotate. When the threaded rod 9 rotates, it drives the traction block 10 to move horizontally on the surface of the base 1. By controlling the rotation direction of the second motor 8, the traction block 10 moves towards the adjusting seat 2. Since the length of the support rod 11 is fixed, when the traction block 10 moves horizontally, it can drive the end of the support rod 11 to move synchronously. The top of the support rod 11 can then drive the adjusting seat 2 to rise, thereby raising the overall height of the cargo box 3 so that the cargo box 3 can adapt to the height of the vehicle body.

[0027] The surface of the cargo box 3 is provided with a pair of pushing structures, which include push rods 12, slides 13, guide rods 14 and springs 15. The slides 13 are symmetrically arranged on the surface of the cargo box 3. The guide rods 14 are fixedly connected to the inside of the slides 13. The bottom of the push plate is slidably connected to the slides 13 and sleeved on the surface of the guide rods 14. The springs 15 are fixedly connected between the slides 13 and the push rods 12 and sleeved on the surface of the guide rods 14. A driving mechanism is provided between the two push rods 12. The driving mechanism includes a rack 16, a gear 17 and a third motor 18. The third motor 18 is fixedly installed on the bottom surface of the cargo box 3. The gear 17 is fixedly installed on the output end of the third motor 18. The rack 16 is fixedly installed on the bottom of the push rods 12 and fits against the bottom surface of the cargo box 3. One end of the rack 16 meshes with the gear 17.

[0028] Please see Figure 4 and Figure 5 The third motor 18 drives the gear 17 to rotate. When the gear 17 rotates, it drives two linear movements. At this time, when the rack 16 moves, it drives the push rod 12 to move synchronously, so that the two push rods 12 move closer to each other. When the push rod 12 moves, it can flatten the boxed goods so that the goods are concentrated towards the middle of the box 3. After the first layer of goods is flattened, the remaining goods are placed on top in sequence. When the push rod 12 moves, it can move synchronously on the surface of the guide rod 14 and compress the spring 15. At this time, the spring 15 accumulates energy. When the goods are flattened, the third motor 18 is controlled to reverse, so that the third motor 18 drives the rack 16 to move in the opposite direction, so that the two push rods 12 move away from each other. At this time, the spring 15 gradually releases energy.

[0029] A storage battery 19 is fixedly installed in the middle of the base 1. The storage battery 19 is electrically connected to the first motor 4, the second motor 8 and the third motor 18.

[0030] Please see Figure 1 The battery 19 is used to power the first motor 4, the second motor 8, and the third motor 18. A controller for controlling the first motor 4, the second motor 8, the third motor 18, and the battery 19 can also be installed on the base 1. The controller is used to control the rotation direction and working status of the first motor 4, the second motor 8, the third motor 18, and the battery 19. Since the connecting arm 7 reciprocates, the distance between the third motor 18 and the battery 19 is always within a certain range. Therefore, the wires used to connect the third motor 18 and the battery 19 will not become tangled due to the rotation of the connecting arm 7.

[0031] At least four casters 20 are fixedly installed on the bottom of the base 1, and the four casters 20 are all fixedly installed in the corners below the base 1.

[0032] Please see Figure 1 The casters 20 are used for the overall movement of the base 1 so as to move it to a location near the carriage when loading.

[0033] Working principle: The third motor 18 drives the gear 17 to rotate. When the gear 17 rotates, it drives two linear movements. At the same time, when the rack 16 moves, it drives the push rod 12 to move synchronously, so that the two push rods 12 move closer to each other. When the push rod 12 moves, it can level the boxed goods, so that the goods are concentrated towards the middle of the cargo box 3, thereby keeping the overall center of gravity of the cargo box 3 in the middle and preventing the goods from shifting during the lifting process. The first motor 4 drives the main shaft 6 to rotate. When the main shaft 6 rotates, it drives the connecting arm 7 to rotate. When the connecting arm 7 rotates, it drives the cargo box 3 to rotate synchronously. At this time, the cargo box 3 always maintains a horizontal state due to its own weight and the hinge state between the connecting arm 7 and the cargo box 3. Therefore, the staff can place the goods on the cargo box 3 and lift the goods to a higher height through the cargo box 3, so that the staff in the carriage can load the goods. The other empty cargo box 3 will descend. After the empty cargo box 3 descends, the staff on the ground can continue to fill the cargo box 3 with goods.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
