The device can efficiently, safely and portably replace the shoveling blade. The specific principles of the portable shoveling blade replacement device of the present application will be described below in combination with more embodiments.

[0021] Specifically, as shown in Figure 1 , Figure 2 and Figure 3 , the portable shoveling blade replacement device of the present embodiment includes a lifting trolley 10 and at least two shoveling components 20, the lifting trolley 10 has a bracket 11, the shoveling components 20 are movably mounted on the bracket 11, and the shoveling components 20 have penetrating pieces 21 for movably penetrating the bolt holes of the shoveling blade 100 to be replaced. Each shoveling component 20 is used for receiving the shoveling blade to improve the stability and safety of the shoveling blade replacement process. By rotating the lifting trolley 10, the bracket 11 can be at different heights, so as to adjust the height of the shoveling blade 100.

[0022] In one or more embodiments, the lifting trolley 10 comprises a main shaft 12 and two wheels 13 rotatably mounted at two ends of the main shaft 12, and the bracket 11 is connected to the main shaft 12, and the angle of the bracket 11 can be adjusted by rotating the main shaft 12.

[0023] Exemplarily, the bracket 11 comprises a connecting rod 11a and a bearing rod 11b, two ends of the connecting rod 11a are connected to the main shaft 12 and the bearing rod 11b respectively, and the shifter assembly 20 is slidably connected to the bearing rod 11b. Among them, the number of connecting rods 11a is two, the connecting rod 11a is connected to the main shaft 12 perpendicularly, and the bearing rod 11b is connected to the connecting rod 11a perpendicularly.

[0024] In one or more embodiments, the shifter assembly 20 comprises a shifter body 22, a sleeve 23 and a plug-in piece 21, the sleeve 23 is installed on the back of the shifter body 22, and the sleeve 23 is slidably sleeved on the bearing rod 11b, and the plug-in piece 21 is installed on the shifter body 22.
