Tractor Suspension Transplanting Machine with Adjustable Planting Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vegetable transplanting machines lack adaptability for different crops in terms of planting depth and spacing, and they do not efficiently automate the process of seedling picking, planting, and watering, leading to inefficiencies and high manual labor costs.
Innovation Solution
A tractor suspension type automatic transplanting machine with a modular design incorporating land wheels, a machine frame, seedling pickup and planting devices, plug tray conveying and recovery systems, and a watering mechanism, allowing for adjustable planting depth and spacing, and enabling automated seedling handling and watering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a semi-automatic transplanter is used, then manual work is reduced, but it cannot meet the stability requirement of all-day planting without manual intervention
Solution Approach 1:
The transplanting machine is designed to perform all transplanting operations automatically without requiring manual intervention throughout the day. The seedling picking mechanism, conveying system, and planting devices work continuously and autonomously, allowing the machine to serve itself complete the full transplanting process from seedling pickup to soil covering without human assistance.
2Speed
If a self-propelled transplanter is used, then mobility is improved, but it cannot meet the efficiency requirement for large-field work
Solution Approach 1:
The transplanting machine is designed with universal adaptability for large-field work through its tractor suspension type structure that can be attached to various tractor models. The machine features adjustable seedling picking mechanisms and conveying systems that can handle different seedling types and planting requirements, making it versatile for various large-scale agricultural operations while maintaining high transplanting efficiency.
3Ease of operation
If a traction type transplanter is used, then mobility is improved, but it cannot automatically control planting depth
Solution Approach 1:
The transplanting machine incorporates automatic depth control mechanisms that monitor and adjust planting depth in real-time. The seedling planting devices are equipped with depth sensing capabilities that provide feedback to the control system, which then automatically adjusts the planting parameters to maintain consistent and accurate planting depth throughout the operation.
4Adaptability or versatility
If planting depth and spacing are fixed, then machine structure is simplified, but adaptability to different crops is poor
Solution Approach 1:
The transplanting machine features dynamically adjustable planting parameters including variable planting depth and spacing controls. The machine structure incorporates adjustable seedling picking mechanisms, movable conveying systems, and adjustable planting devices that can be configured for different crop types and planting requirements, providing adaptability without excessive structural complexity.
5Reliability
If watering function is not included, then machine structure is simplified, but seedling survival rate is affected
Solution Approach 1:
The transplanting machine integrates a watering function combined with the planting operation. The watering device is merged with the seedling planting mechanism, allowing water to be applied directly to planted seedlings immediately after transplantation. This integration improves seedling survival rate while minimizing additional structural complexity by combining multiple functions into a unified system.

AI summary
A tractor suspension type automatic transplanting machine for plug tray seedlings includes land wheels, a machine frame, a three-point linkage, a seedling pickup mechanism, a plug tray conveying device, a plug tray recovery device, seedling separating and planting devices driven by land wheels, and a watering device. Through front and rear drive cylinders, the seedling pickup mechanism is driven to move front and back to pick up seedlings above plug trays and release seedlings above a seedling guide device. Juxtaposed left and right seedling pickup modules in the seedling pickup mechanism are driven by left and right drive cylinders, to move left and right and pick up seedlings after combing, and to release seedlings after separating towards left and right. Plug trays fall onto a plug tray conveyor belt of the plug tray recovery device and slides into a plug-tray-recovery stacking box.
