[0026] When the bucket tooth shape needs to be changed according to demand, by operating the motor 325, the motor's rotational motion is converted into linear motion through the screw rod 326, and the top end of the screw rod 326 is movably connected to the top of the inner wall of the transmission chamber 321.

[0027] See also Figure 3-6The bucket tooth assembly 327 includes a transmission shaft 3271, the inner wall of the transmission shaft 3271 is threadedly connected to the outer wall of the screw rod 326, and the outer wall of the transmission shaft 3271 is rotatably connected to the rotating rod 3272 on both sides.

When the transmission shaft 3271 moves downward, it pulls the two push-pull rod connecting blocks 328 4 moves downward, the push-pull rod connecting block 3284 is connected to the flat-tooth main body 3281 through the flat-tooth push-pull rod 3283, so that the transmission shaft 3271 moves downward, driving the flat-tooth main body 3281 to move downward inside the two chute grooves 3278. As the flat-tooth main body 3281 moves downward inside the two chute grooves 3278, the two chute grooves 3278 are pushed gradually closer together by the push-pull rod 3276, thereby changing the overall shape into the two chute grooves 3278 being closer to each other. Since the top of the chute 3278 is relatively sharp, it is easier to crush hard objects than the combination of the flat-tooth main body 3281 and the two chute grooves 3278.
