Description

Technical Field

[0001] The utility model belongs to the technical field of rice transplanters, and particularly relates to a hydraulic lifting over-ridge device for a rice transplanter. Background Technique

[0002] With the acceleration of the agricultural modernization process, the degree of mechanization in rice planting is increasing day by day. Rice transplanters play a very important role in this process. When traditional rice transplanters are designed, they mainly focus on the stability and accuracy of field transplanting operations. Their chassis height is usually determined according to driving and transplanting operations in flat paddy fields. Generally, in order to ensure the center of gravity stability during transplanting operations and avoid damaging rice seedlings, the ground clearance of the chassis is relatively small. When facing ridges, this low chassis height exposes many problems.

[0003] Currently, existing rice transplanters are relatively heavy and have a limited chassis height. When crossing ridges, the chassis is prone to collide and scrape with the ridges. This not only damages the chassis components of the rice transplanter but also may cause the rice transplanter to be blocked during travel or even get stuck in the soft soil beside the ridges, affecting the operation efficiency and increasing the maintenance cost and operation time cost. For this reason, we provide a hydraulic lifting over-ridge device for a rice transplanter to solve the above problems. Content of the Utility Model
