At the same time, by setting the support frame 2 and further defining the structural form of the trolley walking part 3, the stability of the feeding process is ensured when the feeding screw conveyor 1 does not need to move.

[0028] In order to ensure the stability of the feeding screw conveyor 1 during the moving process and the firmness in the fixed state, trolley walking parts 3 are relatively arranged on the left and right sides below the feeding screw conveyor 1. The trolley walking part 3 further includes a trolley walking part support 305. The driving part 301 is fixedly arranged on the trolley walking part support 305. The trolley walking part supports 305 on the left and right sides are fixedly connected to the support frame 2 through a connecting part 306. Further, trolley walking parts 3 are respectively arranged on the left and right sides below the front and rear ends of the feeding screw conveyor 1.

[0029] For the convenience of movement, the trolley walking part 3 further includes tracks 307 respectively arranged below the first driving walking wheel 302 and the second driving walking wheel 304.
