The dynamic shaft assembly 9 and the linkage assembly 6 include a connecting rod 61 plugged into the output shaft of the master cylinder 2, a first pin 62 respectively plugged into the output shaft of the master cylinder 2 and the connecting rod 61, a felt sheet 67 and a deep groove ball bearing 68 arranged at the end of the connecting rod 61, wherein the felt sheet 67 has good sealing and wear resistance to effectively prevent dust, moisture and impurities from entering the deep groove ball bearing 68, ensuring the normal operation of the deep groove ball bearing 68, a pin 63 for limiting the position of the deep groove ball bearing 68, and a spacer 64, a gasket 65 and a second pin 66 for locking the pin 63 on the connecting rod 61; the second pin 66 is plugged into the pin 63, and the second pin 66 is located on the side of the gasket 65 away from the pin 63.

[0022] The transmission shaft assembly 9 includes a bearing seat 91 connected to the main frame 1 by bolts, a self-aligning ball bearing 93 arranged inside the bearing seat 91, a rotating shaft 92 movably connected to the bearing seat 91 through the self-aligning ball bearing 93, an elastic shaft baffle 94 for limiting the rotating shaft 92, and a baffle ring 95 also connected to the bearing seat 91 by bolts.

[0023] The clamping assembly 7 includes a gripper 71 for grabbing bagged materials, a cross bar 72 fixedly connected to the gripper 71, and a first adapter plate 73 and a second adapter plate 74 respectively fixedly mounted on the cross bar 72. The first adapter plate 73 is fixedly connected to the rotating shaft 92 by bolts, and the second adapter plate 74 is also fixedly connected to the rotating shaft 92 by bolts, and the second adapter plate 74 is also movably connected to the connecting rod 61.

[0024] The main frame 1 is also provided with a limit assembly 8 and a bag pressing assembly 10. The limit assembly 8 includes a baffle 82 for limiting the bagged material and a mounting plate 81 fixedly connected to the main frame 1. The baffle 82 is also fixedly connected to the mounting plate 81. The bag pressing assembly 10 includes a sub-cylinder 101 fixedly connected to the main frame 1 and a quick connector 102 provided on the sub-cylinder 101.

By pressing the bags, the bagged materials can be stacked more tightly and the gaps can be reduced, thereby enhancing the stability of the entire stack body and preventing the stack body from collapsing or the material bags from being damaged due to shaking or bumping during transportation. At the same time, tightly stacked bagged materials can make more effective use of the transportation space, increase the loading capacity of the vehicle, and thus improve transportation efficiency.

[0025] Working principle: the main frame 1 fixes the master cylinder 2, the output shaft of the master cylinder 2 passes through the connecting rod 61, and then the first pin 62 is inserted into the output shaft of the master cylinder 2, so that the connecting rod 61 can be connected to it. At this time, the connecting rod 61 will rise and fall with the rise and fall of the output shaft of the master cylinder 2, and the end of the connecting rod 61 is connected with the pin 63, and the pin 63 is fixed to the connecting rod 61 with the spacer 64, the gasket 65 and the second pin 66. At this time, the felt piece 67 and the deep groove ball bearing 68 can be restricted to the end of the connecting rod 61, and the deep groove ball bearing 68 and the connecting rod 61 are connected. A sliding groove with sealed ends can be formed, and the second adapter plate 74 fixed on the cross bar 72 is located inside the sliding groove. The first adapter plate 73 fixed on the cross bar 72 is fixedly connected to the rotating shaft 92 by bolts, and the rotating shaft 92 is movably connected to the bearing seat 91 fixed on the main frame 1 through the self-aligning ball bearing 93. A groove that cooperates with the elastic baffle 94 for the shaft is provided on the rotating shaft 92, so that the position of the rotating shaft 92 can be limited to the bearing seat 91, and the self-aligning ball bearing 93 is restricted to the bearing seat 91 by the baffle ring 95. At this time, the rotating shaft 92 is connected to the rotating shaft 92. The first adapter plate 73 connected thereto will drive the cross bar 72 to rotate, and the second adapter plate 74 is also connected to the rotating shaft 92, and the gripper 71 is fixed to the cross bar 72; therefore, when grabbing bagged materials for palletizing, the main cylinder 2 is started, and its output shaft drives the connecting rod 61 to slide upward, thereby changing the angle of the second adapter plate 74, so that the cross bar 72 drives the gripper 71 to rotate with the rotating shaft 92 as the center, and the grippers 71 on both sides of the connecting rod 61 rotate inward synchronously, so as to clamp the bagged materials, thereby palletizing. After the bagged materials are placed in the specified position, the main cylinder 2 is started, and its output shaft drives the connecting rod 61 to slide upward, thereby changing the angle of the second adapter plate 74, The auxiliary cylinder 101 on the body frame 1, the output shaft of the auxiliary cylinder 101 is fixed with the push plate 103, and the push plate 103 slides downward with its output shaft, pushing the pressure block 106 to squeeze the bagged material below it, completing the bagging, making the bagged material stacked more tightly, reducing the gap, thereby enhancing the stability of the entire stack body, and the dustproof plate 104 fixedly connected to the cylinder body of the auxiliary cylinder 101 is fixed with the accordion cover 105, and the accordion cover 105 is fixedly connected to the pressure block 106, so the pressure block 106 will move up and down in the vertical direction to meet the use requirements of bagging.
