[0029] In one embodiment, there are at least two transmission wheel groups, and each transmission wheel group is arranged side by side and at equal intervals at the upper end and the lower end of the conveying frame 21 .

[0030] Please see Figure 6 , wherein a material-pickling wheel 26 is arranged on one of the transmission wheels 23 in the transmission wheel group. Material-pickling protrusions 261 are evenly distributed around the four edges of the material-pickling wheel 26; when clamping the seedlings, the material-pickling wheel 26 rotates synchronously with the transmission wheel 23, and the seedlings can be quantitatively delivered through the material-pickling protrusions 261 to prevent clamping of too many seedlings.

[0031] Please see Figure 8 In one embodiment, there are at least two cutting devices 03, and the number of cutting devices 03 is consistent with the number of transmission wheel 23 groups.
