[0017] Figure 1 , 2 The components include: base frame 1, first cylinder connecting plate 2, trolley pusher plate 3, second cylinder connecting plate 4, slide bar locking seat 5, stainless steel plate 6, pusher limit plate 7, cylinder shaft 8, cylinder connecting block 9, slide rail connecting plate 10, drag chain mounting plate 11, drag chain seat 12, protective cover 13, seated linear bearing 14, guide shaft 15, cylinder 16, guide rail 17, floating joint 18, foot seat 19, etc.

[0018] like Figure 1 , 2 As shown, this utility model is a mobile package delivery trolley, including a base frame 1, a guide shaft 15 is installed on the top of the base frame 1, a trolley pusher plate 3 is slidably disposed on the guide shaft 15, and pusher limit plates 7 are respectively provided at both ends of the pusher side of the trolley pusher plate 3.

[0019] A pusher assembly is also installed on the top of the base frame 1 to push the trolley pusher plate 3 to reciprocate along the guide shaft 15. The pusher assembly includes two cylinders 16, which are installed vertically between two first cylinder connecting plates 2. The piston rods of the two cylinders 16 extend and retract in opposite directions. The piston rod of the lower cylinder 16 is connected to the trolley pusher plate 3, and the piston rod of the upper cylinder is connected to the second cylinder connecting plate 4, which is installed on the top of the base frame 1.

[0020] Two guide shafts 15 are arranged parallel to each other on the top of the base frame 1. Two sets of seated linear bearings 14 are installed on the bottom of the trolley pusher plate 3. The seated linear bearings 14 are slidably engaged with the corresponding guide shafts 15. The trolley pusher plate 3 is slidably engaged on the guide shafts 15, which enables reliable and stable movement of the trolley pusher plate 3.

[0021] The two ends of the guide shaft 15 are rotatably supported on the corresponding slide rod locking seat 5, which is installed on the top of the base frame 1.

[0022] Cylinder connecting block 9 is installed on the second cylinder connecting plate 4. Cylinder connecting block 9 is connected to the piston rod end of the upper cylinder 16. The piston rod end of the lower cylinder is connected to the floating joint 18. The floating joint 18 is connected to the trolley push plate 3 through the cylinder shaft 8.

[0023] The base frame 1 is supported by feet 19, which allow for height adjustment of the base frame 1. In practice, to ensure reliable and stable support for the base frame 1, three sets of feet 19 are evenly distributed along the length of the bottom surface of the base frame 1.

[0024] Furthermore, in order to enable the first cylinder connecting plate 2 to reliably move linearly on the base frame 1, a guide rail 17 is provided on the top of the base frame 1, and a slide rail connecting plate 10 is provided on the bottom of the first cylinder connecting plate 2, wherein the slide rail connecting plate 10 and the guide rail 17 are slidably engaged.

The stainless steel plate 6 is located between the two guide shafts 15, and the bottom of the trolley pusher plate 3 is located above the stainless steel plate 6. The trolley pusher plate 3 can push materials forward along the stainless steel plate 6. The pusher limit plate 7 limits the material and prevents the material from falling from both sides of the stainless steel plate 6 during the pushing process. The stainless steel plate 6 is supported and fixed by steel plate supports and locked to the bracket 1 with screws.

[0027] During operation, the ton bag is placed on the stainless steel plate 6. The piston rod of the upper cylinder 16 of the pushing assembly extends, thereby moving the two cylinders 16 together with the two first cylinder connecting plates 2 as a whole, and pushing the trolley pushing plate 3 to move. The trolley pushing plate 3 then moves the ton bag on the stainless steel plate 6. After the upper cylinder 16 moves into position, the piston rod of the lower cylinder extends, moving the trolley pushing plate 3 to move. Together with the initial position, the position movement of the ton bag is achieved at three workstations.
