Composite duckbill for planting machine

Abstract

The invention discloses a composite duckbill for a transplanting machine. The duckbill body includes an inner duckbill body and an outer duckbill body. The mouth body is nested inside the outer duckbill body, and the lower end of the inner duckbill body protrudes from the outer duckbill body. The transplanting machine drives the composite duckbill to rotate with the transplanting connecting rod through the transmission mechanism. Burying into the soil in sequence, the outer duckbill opens first and has a larger opening angle after being buried in the soil to complete the task of digging and making a well cellar, and the inner duckbill opens later and at a smaller opening angle to complete seedling spitting, supporting seedlings, Covering with soil, the production of well cellar, transplanting and watering can be completed at one time in the same pit. The depth is consistent, effectively avoiding buried seedlings and exposed roots during transplanting.

Description

technical field [0001] The invention relates to the technical field of planting machinery, and more specifically relates to a compound duckbill for a planting machine. Background technique [0002] With the vigorous advancement of agricultural modernization, more and more crops are planted in a factory and then transplanted in the field. The promotion of this modern agricultural technology can shorten the growth cycle of crops in the field and promote the early listing of agricultural products. , increase the multiple cropping rate of crops, and achieve agricultural efficiency, which has a huge boosting effect. With the continuous promotion of modern transplanting technology, the demand for transplanting machinery in agriculture will increase. At present, the transplanting mode is divided into two types: transplanting on the film and transplanting under the film. [0003] Transplanting on film can be divided into two methods: film first, then transplant and first transplant...

AI Technical Summary

Problems solved by technology

In order to adapt to the pit-type transplanting under the film, it can well meet the agricultural requirements of the transplanting under the film, but this kind of well-pit transplanting machine adds a digging device and a soil covering device before the ordinary duckbill transplanting machine, resulting in a complicated structure. Secondly, the mode of digging a hole first and then transplanting is not completed in the same cellar at one time. When the ground undulations are large, the consistency of the transplanting depth is poor. Sometimes the transplanting is too deep and the seedlings are buried, and sometimes the transplanting is too shallow and causes Roots exposed
