Description

Technical Field

[0001] The utility model relates to the technical field of conveyors, in particular to a heavy-load ground conveyor for conveying pallets. Background Art

[0002] A heavy-duty ground conveyor is a mechanical device specially designed to carry and transport heavy materials in a ground environment. A heavy-duty ground conveyor is an efficient and reliable material conveying equipment that transports heavy materials from the starting point to the end point through continuous motion. Currently, when transporting pallets, workers will use heavy-duty ground conveyors to transport pallets. Pallets are usually made of wood, plastic or metal, among which wood pallets are the most common.

[0003] After searching, a heavy-load ground conveyor for conveying pallets, application number: CN202121821275.3, is unable to effectively position the pallets when conveying them, which results in the pallets on the conveyor shaking due to vibration or external force when conveying large quantities of pallets stacked together. This shaking increases the risk of pallet collapse, which may not only cause damage to the goods, but also cause personal injury to the staff. Moreover, the conveying height cannot be adjusted, which makes it more troublesome for the staff to unload the pallets from trucks or other transportation equipment onto the conveyor.

After the pallet is transported to the other side by the feed plate 7, the staff can transport and unload the pallet through the feed rollers 20 above the material unloading platform 19 when unloading, which provides convenience for the staff's unloading work.

[0029] Working principle: when the staff needs to transport the pallet, the staff first opens the cylinder 6 above the mobile platform 5, so that the output shaft of the cylinder 6 pushes the feeding plate 7 to rise, and then adjusts the unloading height so that the staff can unload the pallet to the top of the feeding plate 7. When the pallets are stacked and placed above the feeding plate 7, the staff can select the rotating disk 92 on one side, so that the positioning plates 12 on both sides move toward each other, and the stacked pallets are positioned by the positioning plates 12. Then the cylinder 6 is opened again to lower the feeding plate 7 to its original position. After the positioning is completed, the staff can turn on the motor 2 below, so that the driving wheel 3 rotates, and the driving wheel 3 drives the driven wheel 4 to rotate through the belt. When the belt is active, the connecting seat 13 on the belt surface will drive the mobile platform 5 to move to the left to transport the pallet. When the pallet is transported to the far left, the staff can remove the pallet from the feeding plate 7, and can move the pallet to the top of the unloading platform 19, and complete the unloading operation of the pallet through the feeding roller 20, thereby completing the transportation of the pallet.
