[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model controls the third electric telescopic rod to extend backward. When the third electric telescopic rod extends backward, it drives the rear end of the shovel arm to swing downward. When the rear end of the shovel arm swings downward, it drives the bucket to swing downward. When the bucket swings downward and fits the ground, the electric tricycle body is controlled to travel backward. When the electric tricycle body travels backward, the power generated by the electric tricycle body traveling backward will push the bucket to shovel the bulk material on the ground. When the bucket shovels the bulk material on the ground, the third electric telescopic rod is controlled to retract forward. When the third electric telescopic rod is retracted forward, it drives the shovel arm to swing upward. When the shovel arm swings upward, it drives the bucket to swing upward. When the bucket swings upward to the upper end of the load bucket, the bulk material shoveled in the bucket will automatically slide down and be loaded into the load bucket under the action of gravity, thereby facilitating the shoveling and loading of the bulk material.

[0016] 2. The utility model also controls the second electric telescopic rod to extend or retract. When the second electric telescopic rod is extended or retracted, it will drive the bucket to swing up and down. When the bucket swings up and down, it can adjust the up and down shoveling angle of the bucket, so that the bucket can adapt to different bulk material loading conditions, thereby facilitating the shoveling loading of bulk materials and adjusting the shoveling angle of the bucket up and down.

[0023] Main support columns 5 are fixedly installed on both sides of the rear end of the electric tricycle body 1, and there are two main support columns 5, which are symmetrically distributed on both sides of the rear end of the electric tricycle body 1. The outer curved surface in the middle of the main support column 5 is rotatably connected to a shovel arm 6 through a rotating shaft, and a shovel bucket 7 for shoveling materials is rotatably connected to the rear end of the shovel arm 6 through a pin shaft. A connecting rod 8 for connecting the shovel arm 6 is fixedly installed on the inner side of the rear end of the shovel arm 6. The upper end of the middle part of the connecting rod 8 is rotatably connected to a second electric telescopic rod 9 through a pin shaft, and the telescopic part of the upper end of the second electric telescopic rod 9 is tilted backward. The second electric telescopic rod 9 has an upper telescopic portion which is rotatably connected to the outer wall of the upper end of the bucket 7 via a pin shaft. Auxiliary support columns 10 are fixedly installed on both sides of the middle part of the electric tricycle body 1. There are two auxiliary support columns 10, which are symmetrically distributed on both sides of the middle part of the electric tricycle body 1. The outer curved surface of the auxiliary support column 10 is rotatably connected to the third electric telescopic rod 11 via a rotating shaft. The upper telescopic portion of the third electric telescopic rod 11 is tilted backwards. The upper telescopic portion of the third electric telescopic rod 11 is rotatably connected to the upper side of the front end of the shovel arm 6 via a pin shaft.

[0024] Working principle: when in use, the utility model controls the third electric telescopic rod 11 to extend backward. When the third electric telescopic rod 11 extends backward, it drives the rear end of the shovel arm 6 to swing downward. When the rear end of the shovel arm 6 swings downward, it drives the bucket 7 to swing downward. When the bucket 7 swings downward and fits the ground, the electric tricycle body 1 is controlled to travel backward. When the electric tricycle body 1 travels backward, the power generated by the backward travel of the electric tricycle body 1 will push the bucket 7 to shovel the bulk material on the ground. When the bucket 7 shovels the bulk material on the ground, the third electric telescopic rod 11 is controlled to retract forward. When the third electric telescopic rod 11 is retracted forward, it drives the shovel arm 6 to swing upward. When the shovel arm 6 swings upward, it drives the bucket 7 to swing upward. When the bucket 7 swings upward to the upper end of the load bucket 2, the bulk material shoveled in the bucket 7 will automatically slide and be loaded into the load bucket 2 under the action of gravity, thereby facilitating the shoveling and loading of the bulk material.

[0025] When the bulk material in the loading bucket 2 needs to be unloaded, the first electric telescopic rod 3 is controlled to extend backward. When the first electric telescopic rod 3 extends backward, it drives the loading bucket 2 to swing backward. When the loading bucket 2 swings backward, the bulk material in the loading bucket 2 automatically slides to the ground under the action of gravity, thereby facilitating the unloading of the loaded bulk material.

[0026] At the same time, by controlling the second electric telescopic rod 9 to extend or retract, when the second electric telescopic rod 9 is extended or retracted, it will drive the bucket 7 to swing up and down. When the bucket 7 swings up and down, it can adjust the up and down shoveling angle of the bucket 7, so that the bucket 7 can adapt to different bulk material loading conditions, thereby making it easy to shovel and load the bulk material while facilitating the up and down adjustment of the shoveling angle of the bucket 7.
