[0035] Embodiment 2 The embodiment provides a bucket mechanism for a bulldozer, which is based on the embodiment 1 and increases the soil discharge assembly 7.

[0036] As shown in Figures 7-12 The bottom wall of the bucket 1 is provided with a through slot 101 extending along the width direction thereof; The soil discharge assembly 7 comprises a bottom pipe 6, two spiral impellers one 72, two motors one 71 and two vertical pipes 73. The bottom pipe 6 is horizontally arranged below the through slot 101 of the bucket 1, the upper half circumferential wall of the bottom pipe 6 is provided with a discharge hole in communication with the inside of the bucket 1, and the lower half circumferential wall is in a closed structure to close the through slot 101; The two spiral impellers one 72 are coaxially arranged in the inside of the bottom pipe 6 and are separately arranged at the two ends of the bottom pipe 6. The two motors 71 are respectively fixed at both ends of the axial direction of the bottom tube 6, and their output shafts extend into the bottom tube 6 to drive the corresponding spiral impellers 72. The bottom ends of the two vertical tubes 73 are respectively connected to the end regions of both ends of the bottom tube 6, and the end regions are located at the end of the bottom tube 6 near the motor 71.

[0037] Specifically, the soil discharge assembly 7 also includes a spiral impeller 75 and a motor 74; The second spiral impeller 75 is installed inside the vertical tube 73, and the bottom end of the second spiral impeller 75 extends into the bottom tube 6; The second motor 74 is fixedly installed at the top of the vertical pipe 73, and the output end of the second motor 74 is connected to the second spiral impeller 75 for transmission. In a preferred embodiment, such as Figure 12 As shown, the soil discharge assembly 7 also includes a first rectangular tube 76 and a second rectangular tube 77; The rectangular tube 76 is inserted into the top of the vertical tube 73, and its extension direction is away from the bucket 1; The second rectangular tube 77 is slidably connected to the end of the first rectangular tube 76 away from the vertical tube 73, and can move along the length of that end.

[0039] It should be noted that in this embodiment, when the bucket 11 is shoveling soil forward, it needs to discharge soil to both sides directly to the sides of the river or ditch (the width of the river or ditch is adapted to the width of the bucket 11). The motor 1 71 is started to drive the spiral impeller 1 72 to rotate, and the soil falling into the channel 101 in the bucket 1 is transported to one side of the bottom pipe 6. Then the motor 2 74 is started to drive the spiral impeller 2 75 to rotate, and the soil in the bottom pipe 6 is transported to the vertical pipe 73 and discharged from the rectangular pipe 1 76 and the rectangular pipe 2 77. The rectangular pipe 2 77 can slide along the rectangular pipe 1 76 to adjust its length, and is fixed by rotating the insertion rod 771 at its end to the limiting hole 701 on the rectangular pipe 1 76, thereby precisely controlling the soil discharge position. Thus, the bucket 1 does not need to discharge the soil in the bucket 1 externally, and can quickly discharge the soil in the bucket 1 to the slope. This reduces the original repeated operation of loading and unloading soil in the bucket 1, thereby improving the efficiency of river and ditch excavation and reducing the difficulty of operation for workers.
