Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and in particular relates to a duckbill device of a pond digging and transplanting machine. Background Art

[0002] With the continuous development of agricultural machinery technology, the transplanting of seedlings has gradually changed from manual transplanting to mechanized transplanting. The same is true for flue-cured tobacco planting. The mechanical transplanting device for tobacco seedling transplanting uses a duckbill transplanter, which has the characteristics of high transplanting efficiency and high survival rate. However, the existing duckbill transplanters on the market are conical structures. Due to the large conical space, when the seedlings are too small, it is difficult for the seedlings to remain vertical when they fall to the bottom of the cone, resulting in the seedlings being skewed and lodged in the soil, which is not conducive to the growth of the seedlings. Summary of the invention

[0003] In order to solve the above problems, the utility model provides a duckbill for a seedling transplanter, which is used to prevent the seedlings from tilting and falling over during the transplanting process.

[0007] Below the left duckbill seat 2 and the right duckbill seat 3, three-section semi-conical opening and closing pieces 11 are fixedly connected respectively. The opening and closing piece 11 includes, from top to bottom, a vertical cylinder 12 and a first arc 13 and a second arc 14 with the same bending direction and different bending radii, as well as a first connecting section 15 connecting the vertical cylinder 12 and the first arc 13, and a second connecting section 16 connecting the first arc 13 and the second arc 14, which together constitute a three-section arc transition structure.

[0008] Preferably, the traction line 8 is one, extending along the arc-shaped side wall on either side of the left duckbill seat 2 and the right duckbill seat 3, and is fixed on the outside of the side wall of the right duckbill seat 3 after penetrating the side wall.

[0009] Preferably, there are two traction lines 8, which extend along the arc-shaped side walls of the left duckbill seat 2 and the right duckbill seat 3 respectively, penetrate the side wall of the right duckbill seat 3 and are fixed on the outside thereof.

[0010] Preferably, a plurality of fastening buckles 17 are arranged at intervals along the traction line 8 on the installation path of the left duckbill seat 2 and the right duckbill seat 3 to fit the traction line 8 to the side walls of the left duckbill seat 2 and the right duckbill seat 3 .
