Ditching type seedling planting device used in vegetable dry land transplanting machine

Abstract

The invention discloses a ditching type seedling planting device used in a vegetable dry land transplanting machine. A duckbilled seedling planting device is prone to soil adhesion in clayed soil. The ditching type seedling planting device used in the vegetable dry land transplanting machine comprises a rack mechanism, a planting mechanism and a soil covering wheel mechanism; the planting mechanism comprises a ditcher, a tension spring, a cam, a sliding block component, a push rod combined body, rotating cup doors, a fixed cup door and a sliding groove rod; a bearing roller hinged to the front end of the push rod combined body and the cam form a cam pair; the push rod combined body and the cam are connected through the tension spring; the fixed cup door is fixed to the rear end of the push rod combined body; the middle portion of the sliding block component is fixed to the push rod combined body, and each of the two ends of the sliding block component and a corresponding linear guide rail form a movement pair; the tops of the inner sides of the two rotating cup doors are hinged to the two sides of the fixed cup door; the sliding groove rod fixed to the rotating cup doors and a groove pin form a cylindrical pair; and the groove pin is fixed to the bottom of a groove pin fixing plate which is fixed to a reference supporting block. The ditching type seedling planting device used in the vegetable dry land transplanting machine avoids damage to pot seedlings in the seedling pushing process and is compact in structure.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and relates to a vegetable transplanter, in particular to a ditching type seedling planting device used in a vegetable dryland transplanter. Background technique [0002] At present, most of the semi-automatic or fully automatic vegetable transplanting machines used in my country are based on duckbill vegetable transplanting machines. In most transplanting operations, the duckbill seedling planting device has a better planting effect than other seedling planting devices. However, this seedling planting device is prone to clay. For plants suitable for cultivation in sticky soils such as rape and corn, the problem of duckbill seedling planting device carrying soil during planting operations will be magnified, which will have a greater impact on its planting effect. On the other hand, the duckbill type seedling planting device has a complex structure, and the whole mechanism is not easy to prod...

AI Technical Summary

Problems solved by technology

However, this kind of seedling planting device is prone to clay soil. For plants suitable for cultivation in sticky soil, such as rape and corn, the problem of duckbill seedling planting device carrying soil during planting operations will be magnified, which will have a greater impact on its planting effect

On the other hand, the duckbill type seedling planting device has a complex structure, the whole mechanism is not easy to produce and process, and the cost is relatively high

And in some cases where the soil conditions are poor, the duckbill parts are easy to be damaged due to touching the stones inside the soil, causing unnecessary troubles to the farmers, so that the planting effect is not ideal
