AI Technical Summary

Technical Problem

Traditional plastic seedling tray cultivation suffers from environmental pollution, high labor intensity, and low efficiency. In trayless burlap seedling cultivation technology, seedling cutting relies on manual labor or low-level machinery, which is inefficient and costly. Furthermore, existing machinery lacks precise guidance and positioning, resulting in skewed cutting trajectories and uneven edges, affecting the quality of subsequent operations.

Method used

Design a self-propelled seedling cutting device, including a walking mechanism, a longitudinal cutting mechanism, and a transverse cutting mechanism. It adopts a new energy power supply module and drives the longitudinal and transverse cutting blades through electric push rods and electric cylinders to realize the automated cutting of seedlings. Combined with a collaborative control module, it ensures cutting accuracy and efficiency.

Benefits of technology

It improves cutting efficiency and precision, reduces labor costs, minimizes damage to seedlings, conforms to the concept of green environmental protection, is suitable for flexible operation in narrow and elongated plots, and reduces the rate of missed planting and the cost of replanting.

Abstract

This utility model relates to the field of agricultural machinery technology and discloses a self-propelled seedling cutting device. The walking mechanism drives the device to move along the length of the seedbed. An electric push rod on the longitudinal cutting mechanism drives the longitudinal cutting blade to rise and fall in conjunction with its rotation during movement, allowing the longitudinal cutting mechanism to cut the seedlings longitudinally during travel and adjust the depth of penetration into the soil. A linear screw module on the transverse cutting mechanism drives two transverse cutting blades to move laterally, and an electric cylinder on the transverse cutting mechanism drives the two transverse cutting blades to rise and fall, enabling transverse cutting of the seedlings even when the device is stationary. It also allows for lateral movement of the cutting position and adjustment of the cutting depth. This utility model adopts a lightweight, unmanned design, reducing pressure on seedlings while improving work efficiency and reducing labor costs. It also offers high cutting precision, ensuring work quality, and the power and cutting modules can be quickly replaced.
