Combined duck bill for transplanter

Abstract

The invention discloses a combined duck bill for a transplanter. The combined duck bill body comprises an inner duck bill body and an outer duck bill body, wherein the inner duck bill body and the outer duck bill body are hinged to the lower end of a transplanting connecting rod through a pin shaft; the inner duck bill body is nested at the inner part of the outer duck bill body; the lower end ofthe inner duck bill body stretches out of the outer duck bill body; the transplanter drives the combined buck bill to rotate together with the transplanting connecting rod through a transmission mechanism; the inner duck bill body and the outer duck bill body can sequentially stretch into soil, the outer duck bill body can be firstly opened after stretching into the soil, the opening angle is larger, and a task for digging soil to make a well pit can be completed; the inner duck bill body can be opened later, the opening angle is smaller, seedling emerging, seedling supporting and soil covering in the well pit can be completed, and operation items of well pit preparation, transplanting, watering and the like can be completed in the same pit in one time. According to the combined duck billdisclosed by the invention, agricultural requirements of well pit transplanting are met, the structure of the transplanter is simplified, the consistency of transplanting depth is ensured, and seedling burying and root exposing during transplanting can be effectively avoided.

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
