Abstract

The invention relates to a V-shaped seedling pin, pertaining to the technical field of agricultural machinery. The seedling pin comprises a pin handle at one end of a pin body and cutting sections at the other end thereof, wherein, the front end of the cutting section is cut with a V-shaped breach in the horizontal direction; the V-shaped breach is communicated with a straight channel extending towards the middle of the body so as to respectively form a left cutting section with a left pin point and a right cutting section with a right pin point; downward vertical edge folds are respectively formed at the outside of the left cutting section and the right cutting section; the front end of the vertical edge fold is cut with a vertical V-shaped concave breach one edge of which close to the pin point forms a main cutting blade and the other edge of which far from the pin point forms an auxiliary cutting blade. Since double V-shaped cutting blades are formed, the main cutting blade and the auxiliary cutting blade jointly act along the cutting moving track of the seedling pin to cut in a seedling block in a sliding way and complete the point-line-plane cutting process from the upper end and the lower end gradually, which can greatly reduce the tearing of the seedling block and ensure the tidy and correct cutting of the seedling block.

Description

Technical field

[0001] The invention relates to a seedling needle matched with a seedling transplanter, in particular to an improvement in the structure of the seedling needle, and belongs to the technical field of agricultural machinery. Background technique

[0002] The seedling needle is the executive part of the seedling transplanter, and its function is to cut the seedling block containing an appropriate amount of seedlings from the larger seedling block by reciprocating relative movement with the seedling door to transport it to the seedling transplanting mechanism.

[0003] As far as the applicant understands, the existing seedling needles are all needle-shaped, that is, there is only one cutting edge. When picking the seedlings, the cutting is mainly based on the relative movement between the seedling needle and the seedling door. However, due to the gap between the seedling needle and the seedling door, and the seedling block will follow the cutting process, the tearing ...
