AI Technical Summary

Technical Problem

Existing ride-on paddy field ditching machines lack stability in soft paddy fields, are difficult to move on the road surface, and have inconvenient auxiliary wheel adjustments, which affects operating efficiency and ditch quality.

Method used

A rideable paddy field ditching machine with adjustable auxiliary wheels was designed. The machine uses a lifting mechanism to flexibly raise and lower the auxiliary wheels, and combined with a linkage group and shock absorbers, it ensures the machine's stability and ease of operation under different ground conditions.

Benefits of technology

The system enables automatic locking of the auxiliary wheels during ditching operations in paddy fields, ensuring machine stability and ditching quality. At the same time, the auxiliary wheels can be lowered when traveling on roads to reduce impact and extend service life.

Abstract

This utility model provides a rideable paddy field ditching machine with adjustable auxiliary wheels, including a frame, a front wheel, and two auxiliary wheels. The front wheel is mounted on the front end of the frame via a reducer, and the two auxiliary wheels are mounted on both sides of the rear end of the frame. A lifting mechanism for raising and lowering the auxiliary wheels is also installed at the rear end of the frame. The lifting mechanism includes a gearbox, a pair of linkage groups, a pair of shock absorbers, and a lifting assembly. The gearbox is fixedly mounted on the rear end of the frame and located above the auxiliary wheels. The pair of linkage groups are mounted on the gearbox and located on both sides of the frame. One end of the shock absorber is connected to the linkage group on the same side, and the other end of the shock absorber is connected to the auxiliary wheel on the same side. The connecting end of the auxiliary wheel is connected to the linkage group on the same side. The lifting assembly is connected to one of the linkage groups. In this utility model, rotating the lifting handle releases the upper and lower locking rods from locking the gear linkage, and then rotating the gear linkage with the lifting handle releases the self-locking, thereby raising the auxiliary wheels.
