[0002] Feed packaging is a crucial step in ensuring feed quality and facilitating transportation and storage. Appropriate packaging effectively prevents feed from getting damp, contaminated, and damaged, extends shelf life, and reduces losses during transport. Common feed packaging materials include plastic bags, woven bags, and paper bags. Packaging design needs to consider the material's moisture resistance, durability, and environmental friendliness. With technological advancements, some smart packaging materials are also being applied in the feed industry, enabling the monitoring of feed freshness and quality. Overall, good feed packaging helps enhance the market competitiveness of feed products.

[0003] Material handling lifts are devices used for material handling and lifting, widely used in warehousing, production lines, and logistics industries. They can lift feed packaging from low to high places or lower items from high places to low places, greatly improving work efficiency. The design of the lift includes electric or hydraulic drive systems, making it easy to operate and highly safe. Common types include fixed and mobile types, which can be selected according to usage needs. By reducing manual handling, it not only improves production efficiency but also reduces labor intensity. Material handling lifts are an indispensable piece of equipment in modern warehousing and logistics.

[0004] The feed handling lifting platform uses hydraulic or electric power to lift or lower feed packages to a designated height for convenient transfer or transportation. However, in traditional feed handling lifting platforms, the platform used to place the feed packages does not have a limiting structure, and the feed packages are prone to tilting or even falling from a height, causing damage.

The housing 10 is used to connect and protect the internal parts. The springs 11 are used to push the piston 12 to move. The piston 12 is used to cause the positive and negative pressure inside the housing 10 to move back and forth. The switching mechanism includes a push rod 13 that bears the thrust of the cam 15 to move the piston 12, a gear 14 that drives the cam 15 to rotate, the cam 15 that pushes the push rod 13 to move, a pipe 16 for conveying lubricating oil, a one-way valve 17 to prevent lubricating oil backflow, a valve 18 for controlling the opening and closing of the pipe 16, and an oil tank 19 for storing lubricating oil. The cam 15 abuts against the front of the push rod 13, enabling it to push the push rod 13. The piston 12 is slidably connected to the inner wall of the housing 10, and the push rod 13 is slidably connected to the inside of the housing 10.

[0035] Working Principle: When using this device to transport feed packages, first adjust the position of the limiting plate 3 according to the size of the feed package. By moving the sliding plate 6 to compress the spring 5, the insert rod 7 retracts into the outer shell 4 and disengages from the limiting plate 3. At this time, the stop block 8 will automatically fall down and block the outlet of the insert rod 7. Then, start moving the limiting plate 3 to block the feed package. At this time, pull the stop block 8 upward to disengage it from the insert rod 7. The spring 5 will immediately push the sliding plate 6 to reset the insert rod 7 and reinsert it into the limiting plate 3, keeping the limiting plate 3 stable. Then, the device can be used normally. Place the feed package on the platform 2, and use the hydraulic cylinder to move the platform 2 up and down along the bracket 1 to transport it, thereby completing the transportation and preventing the feed package from falling. After a period of time, wear will occur due to the back-and-forth movement of the platform 2 and the limiting plate 3. At this time, it is necessary to add lubricating oil in time. By opening the valve 18, the second spring 11 will instantly push the piston 12 to drive the push rod 13 to reset. Then, when the platform 2 moves, the rack 9 will cause the gear 14 to drive the cam 15 to rotate. The cam 15 will push the push rod 13 to compress the second spring 11. The piston 12 moves back and forth to switch the positive and negative pressure of the sleeve 10. With the cooperation of the two one-way valves 17, the lubricating oil in the oil tank 19 is transported along the pipe 16 to the friction point between the platform 2 and the bracket 1 to achieve lubrication. When it is not necessary to add oil, simply close the valve 18 and push the piston 12 to the rearmost position to stop pumping oil. The operation is convenient and labor-saving.
