Abstract

The invention discloses a transverse and longitudinal profiling device for a planting mechanism and a control method, the transverse and longitudinal profiling device comprises a frame, signal acquisition units, a signal feedback control system, a hydraulic execution system, a planting frame lifting mechanism, a planting frame and hydraulic profiling mechanisms; the signal acquisition units at the left side and the right side of the planting frame are connected by the signal feedback control system and the hydraulic execution system, the signal acquisition units sense changes of the distance between the signal acquisition units at the left side and the right side, the signal feedback control system controls the hydraulic execution system to drive the hydraulic profiling mechanisms at the left side and the right side to lift up and down respectively so as to drive the planting frame to lift up and down or rotate left and right to ensure consistent relative height of a duck mouth planting component and a ridge side, and planting depth profiling of the planting component can be realized. A distance sensor is used to sense terrain changes, and the distance sensor is sensitive to respond and has no delaying advancing phenomenon. The transverse and longitudinal profiling device has the advantages of small load, small bending moment, uniform force and simple structure, can ensure uniform planting depth, improves planting quality, and realizes the requirement of transplanting in a dry land.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery equipment transplanting machines, and in particular relates to a ground profiling device with a multi-row planting mechanism for a ride-on transplanting machine. Background technique [0002] Seedling transplanting can not only shorten the growth cycle, improve land utilization, but also reduce labor force, reduce production costs, etc. It can be seen that it has considerable social and economic benefits. At present, the domestically developed transplanting machines mainly include flexible round Disc type, hanging cup type, chain clip type, seedling guide tube type, etc. With the development of the modernization process, there will be more and more demands for pot seedling transplanting, and the transplanting machine will gradually develop from semi-automated to fully automated. Ensuring the quality of transplanting is the prerequisite for the development of transplanting technology...

AI Technical Summary

Problems solved by technology

For the profiling of the chassis, it is obvious that the load of the hydraulic system is relatively large, the impact is large, the structure is complicated, and the cost is high, and for multi-row transplanting, the influence of lateral height difference on planting quality cannot be considered

Patent CN204634349U discloses a hydraulic planting mechanism, which obtains the ups and downs of the ground through the ground sensing mechanism, feeds back to the hydraulic lifting actuator of the planter, and controls the expansion and contraction of the hydraulic cylinder to drive the lifting of the follower mechanism of the planter, thereby ensuring the planting parts The relative height between the planting mechanism and the ground, but it is only for the longitudinal profiling of the planting mechanism, and the ground sensing wheel is located at the rear wheel of the chassis, which has an advanced phenomenon in the profiling of the planting parts. The collision damage of the planter will affect the seedling quality of the planter. The planting mechanism has a large bending moment, low strength and poor applicability.

[0004] At present, walk-behind transplanters rely on the lifting of the chassis to realize the profiling of the planter to the ground. When working, hydraulic cylinders are required to drive the entire chassis frame to move up and down, which is relatively heavy, and requires a large hydraulic system and high cost. The structure is complex and the operability is poor; for traction and ride-on transplanters, the uniformity of the planting depth is achieved by lifting and lowering the working platform, but only for the longitudinal profiling of a single row or two rows, and the hydraulic cylinder is used by the profiling wheel. The mechanical link mechanism is used to adjust the expansion and contraction of the hydraulic cylinder. The precision is not high, and the profiling lags or advances. For multi-row transplanting, the factors affecting the lateral profiling will be more prominent, and the applicability is poor, and the planting quality is poor.
