Automatic balance device of rice transplanter

Abstract

The invention discloses an automatic balancing device of a transplanter, which not only has function of lifting and profiling, but also has function of controlling the balance of the left, the right and the horizontal; the left, right and horizontal balance control comprises a hydraulic unit, a sensor component, a balancer assembly, a chain box and a travelling wheel; by applying the principle of universal gravitation and balance lever, a weight of a sensor finds balance automatically to control the hydraulic system, and a hydraulic cylinder drives the relevant components, thus realizing the control of the left, the right and the horizontal of the machine body; the automatic balancing device can avoid the phenomenon that the planting depth of seedlings is not identical, the planting depth of one side of the left side and the right side is deep, the planting depth of the other side thereof is low and the seedlings are floating, can reduce the labor intensity and improve the work quality and production efficiency.

Description

technical field [0001] The invention relates to mechanical fields such as engineering machinery and agricultural machinery, and in particular to a mechanism for realizing automatic balance of a rice transplanter by using a balance lever and the principle of gravity and adopting hydraulic technology. Background technique [0002] The rice transplanter has been vigorously promoted in rural areas, which greatly reduces the labor intensity of farmers and improves labor production efficiency. However, the existing rice transplanter requires the paddy field to be level when working in the farmland. The planting depth of the seedlings is inconsistent and the seedlings are floating. At present, most of the walk-behind rice transplanters sold in the domestic and foreign markets only involve the function of lifting and profiling. The machine can only control the profiling of the front and back due to the unevenness of the paddy field, but cannot achieve the control of the left and rig...

[0002] The rice transplanter has been vigorously promoted in rural areas, which greatly reduces the labor intensity of farmers and improves labor production efficiency. However, the existing rice transplanter requires the paddy field to be level when working in the farmland. The planting depth of the seedlings is inconsistent and the seedlings are floating

At present, most of the walk-behind rice transplanters sold in the domestic and foreign markets only involve the function of lifting and profiling. The machine can only control the profiling of the front and back due to the unevenness of the paddy field, but cannot control the horizontal balance of the left and right.

In actual operation, due to factors such as the unevenness of the field and the inclination of the field, it is easy to cause the left and right wheels to not be at the same horizontal position. The lifting profiling device can only control the height of the whole machine, but cannot control the balance of the whole machine in the left and right horizontal directions. , leading to inconsistencies in the planting depth of the seedlings, and even the phenomenon that the planting depth is very deep on the left and right sides, and the seedlings are floating on the other side, and the control is difficult, labor consumption is large, and the production efficiency is affected
