[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A convenient bagging support cart includes: a lower base plate 1, with three sets of uprights 2 fixedly connected to its top. Connecting rods 3 are inserted into the interior of each of the three sets of uprights 2. An upper support 4 is fixedly connected to the top of each of the three sets of connecting rods 3. Several sets of hooks 5 for opening the bag openings are fixedly connected to the top of the upper support 4. By setting up the interlocking connection between the three sets of uprights 2 and the connecting rods 3, stable support is provided for the upper support 4 and the hooks 5, while also allowing for height adjustment, thus ensuring structural stability and adjustment feasibility. Furthermore, the uprights 2 are made of thickened square tubing, further enhancing their bending resistance and ensuring that the hooks 5 will not shift due to deformation of the support when loading heavy objects, thereby improving the long-term reliability of the equipment.

[0025] The connecting frame 6 is fixedly connected to one side wall of one of the columns 2. The connecting frame 6 is equipped with a lifting assembly 7 for height adjustment of the upper support 4 and several sets of hooks 5. The movable end of the lifting assembly 7 is fixedly connected to the upper support 4 via a fixing block 8. By setting the connecting frame 6 and the fixing block 8, the lifting assembly 7 is securely connected to the upper support 4, ensuring that the adjustment force of the lifting assembly 7 can be effectively transmitted to the upper support 4, thus achieving the effect of ensuring the stability of the height adjustment transmission. At the same time, the connecting frame 6 adopts a triangular reinforcing rib design, dispersing the lateral tensile force of the lifting assembly 7 on the column 2, further improving the fatigue resistance of the overall structure.

[0026] The lifting assembly 7 includes a screw 701, with its top and bottom ends rotatably mounted on the inner top and bottom of the connecting frame 6, respectively. The top of the screw 701 passes through the connecting frame 6 and is fixedly connected to a handwheel 702. A movable block 704 is threadedly connected to the outer wall of the screw 701 via a threaded sleeve 703. By welding the movable block 704 to the fixed block 8, the lifting movement of the movable block 704 can directly drive the upper bracket 4 and the hook 5 to move synchronously through the fixed block 8, avoiding the bracket tilting problem caused by errors in multiple connection points. At the same time, the contact surface between the fixed block 8 and the upper bracket 4 uses anti-slip rubber pads, reducing noise generated by direct metal friction and improving stability during adjustment. By setting up the lifting assembly 7 consisting of the screw 701, handwheel 702, threaded sleeve 703, and movable block 704, the rotation of the screw 701 drives the movable block 704 to move up and down, and the handwheel 702 facilitates manual adjustment by the operator, achieving the effect of precise height adjustment of the hook 5 and convenient operation.

[0027] The movable block 704 serves as the movable end of the lifting assembly 7, and the fixed block 8 is fixedly connected to one side of the movable block 704. By setting the fixed connection between the movable block 704 and the fixed block 8, the lifting movement of the movable block 704 can directly drive the upper bracket 4 and the hook 5 to move synchronously, thus ensuring the synchronization of height adjustment.

[0028] A guide protrusion 9 is fixedly connected to one side of the movable block 704. A guide groove 10 adapted to the guide protrusion 9 is formed on the inner wall of one side of the connecting frame 6. The guide protrusion 9 is slidably connected inside the guide groove 10. By setting the sliding engagement between the guide protrusion 9 and the guide groove 10, the movement trajectory of the movable block 704 is restricted, preventing the movable block 704 from deviating as the screw 701 rotates, thus ensuring the stability and accuracy of the lifting movement of the movable block 704. In addition, the inside of the guide groove 10 is coated with a wear-resistant lubricating coating, reducing the risk of wear after long-term use and extending the service life of the guide structure.

[0029] The column 2 has an internal groove 11 that matches the connecting rod 3, and the connecting rod 3 slides into the groove 11. By allowing the groove 11 inside the column 2 to slide into the connecting rod 3, the groove 11 radially limits the connecting rod 3, preventing it from shaking or coming off due to lateral forces during adjustment. It also reduces friction between the connecting rod 3 and the inner wall of the column 2, making height adjustment smoother. Furthermore, a dustproof brush strip is installed at the opening of the groove 11, effectively preventing dust and particles from entering the groove 11 and avoiding adjustment malfunctions caused by obstructions. The sliding connection between the groove 11 inside the column 2 and the connecting rod 3 provides guidance for the up-and-down movement of the connecting rod 3, preventing it from shaking during adjustment and improving the stability of the connecting rod 3's movement.

[0030] Several sets of retaining rods 12 are fixedly connected sequentially between the three sets of uprights 2. By setting several sets of retaining rods 12 to connect the three sets of uprights 2, the connection strength between the uprights 2 is enhanced, forming a more stable overall frame, thereby improving the overall structural rigidity and deformation resistance of the flatbed truck. At the same time, the retaining rods 12 adopt a hollow tube design, which reduces the overall weight while ensuring strength, making it easier for users to move or transport the equipment.

[0031] Four sets of casters 13 are symmetrically fixedly connected to the bottom of the base plate 1. These four sets of casters 13 allow the cart to move flexibly, facilitating transfer between different work locations and improving its usability. All four sets of casters 13 are self-locking swivel casters. The four sets of casters 13 allow the cart to turn and move flexibly, facilitating rapid transfer between different work sites and expanding the equipment's applicability. The self-locking swivel casters can be quickly locked using a foot-operated brake device, preventing the cart from slipping due to external forces or uneven ground during operation, ensuring safety during bagging operations. The self-locking swivel casters retain the 360-degree rotation flexibility of traditional casters while locking the cart in place during operation, avoiding the cumbersome operation of traditional fixed casters requiring additional support. Furthermore, the bearings of the casters are sealed to prevent moisture and dust from entering, extending wheel life and reducing maintenance costs.

[0032] Working principle: The operator rotates the handwheel 702, which drives the screw 701 to rotate. The screw 701 drives the movable block 704 to move up and down along the guide groove 10 through the threaded transmission. The movable block 704 drives the upper bracket 4 and the connecting rod 3 to rise and fall synchronously through the fixed block 8. The connecting rod 3 slides in the slide groove 11 of the column 2 to ensure the stability of the adjustment process. After the hook 5 moves to the target height with the upper bracket 4, the operator stops rotating the handwheel 702 to complete the height adjustment. The bag opening is placed on the hook 5, and the hook 5 is used to keep the bag opening open. The trolley is pushed to the material source (such as a grain pile or a granular conveyor belt) by the moving wheels 13 to start bagging. After bagging is completed, the self-locking casters are locked to prevent the trolley from moving, and then the full bag is removed. The three sets of uprights 2 form a stable frame through the stop bar 12. The cooperation between the guide protrusion 9 and the guide groove 10 prevents the movable block 704 from shifting, ensuring the transmission accuracy of the lifting assembly 7. The sliding connection between the slide groove 11 and the connecting rod 3 prevents the support from shaking. The overall structure maintains high rigidity during adjustment and operation. Through the synergistic effect of the above structure and principle, the device achieves precise and stable adjustment of the hook 5 height, while taking into account structural strength and ease of movement, significantly improving the efficiency and safety of bagging operations.

[0033] 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.
