Hydraulic contour-following planting mechanism

Abstract

The invention discloses a hydraulic contour-following planting mechanism which comprises a ground sensing mechanism, a hydraulic actuating mechanism and a planting device servo mechanism. The ground sensing mechanism is used for acquiring the undulation condition of ground and feeding the undulation condition of the ground back to the hydraulic actuating mechanism to control a hydraulic cylinder to stretch or draw back to drive the planting device servo mechanism to move up or down so as to ensure a consistent relative height between a duck bill planting component and the ground. The hydraulic contour-following planting mechanism is simple in structure and easy to popularize. The rear planting device servo mechanism adopts a parallelogram link structure, can bear a heavy load and amplify displacement, and ensures the balance and verticality of a planting device during a contour-following process, thus ensuring the uniformity of planting depth during a transplanting process, improving the planting quality and better meeting the requirement of field transplanting in dry land.

Description

technical field [0001] The invention belongs to the technical field of dryland transplanting machines, in particular to a transplanting machine planting mechanism with ground profiling capability. Background technique [0002] Seedling transplanting is an important production link in the cultivation of vegetables and other crops. Transplanting in dry land can greatly improve the survival rate of seedlings and reduce secondary replanting. my country began to develop dryland transplanting machines from the end of the 1950s, and successively carried out relevant experimental research on vegetables such as cotton and corn, and developed various types of transplanting machines. The planter is the core component of the transplanting machine except for the seedling-taking mechanism. It provides seedlings by the seedling-taking mechanism or manually, and then plants the seedlings in the ground. It has the advantage of upright planting and can reflect the transplanting machine Devel...

Problems solved by technology

However, the chassis profiling requires the hydraulic cylinder to drive the whole frame to move, and the load that the hydraulic cylinder needs to bear is particularly high. At this time, it is necessary to choose a hydraulic system with a large bearing capacity, which greatly increases the cost; The inertial force on the hydraulic cylinder is particularly large during the movement process. Long-term high-load and continuous work may cause damage to the hydraulic cylinder, which will eventually affect the efficiency of planting. Moreover, most of the chassis profiling has complex structures and poor operability, making it difficult to Achieve large-scale promotion
