Embodiment Construction
[0026] As shown in the figure, a planting depth automatic control device for a transplanting machine, the transplanting machine includes a planter, and the planting depth automatic control device includes:
[0027] The synchronous belt movement device is used to drive the planter in the transplanter to move up and down to realize the process of seedling picking and planting;
[0028] The ground profiling mechanism, including the ground profiling plate and the axially movable connecting rod connected with the ground profiling plate in rotation, the ground profiling plate is used to simulate the flatness of the ground and provide a reference for the detection of the planting depth control system;
[0029] The planting depth control system, by comparing with the simulation results of the ground profiling mechanism, detects and collects the starting point information of the planter's entry into the soil, and controls the movement of the synchronous belt movement device according to...

The invention provides an automatic planting depth control device for a transplanter. The transplanter comprises a planter; the automatic planting depth control device comprises a synchronous belt moving device, a ground profiling mechanism and a planting depth control system, wherein the synchronous belt moving device is used for driving the planter in the transplanter to move up and down to achieve seedling receiving and planting processes; the ground profiling mechanism comprises a ground profiling plate and an axially moving connection rod rotationally connected with the ground profiling plate, and the ground profiling plate is used for simulating the ground levelness to provide a reference basis for detection of the planting depth control system; the planting depth control system detects the position relation between the planter and the ground profiling mechanism in real time, judges whether the bottom of the planter makes contact with the surface of soil and controls the synchronous belt moving device to move to control the planting depth of the transplanter when the bottom of the planter just makes contact with the surface of the soil. The automatic planting depth control device has the benefits as follows: a traditional planting depth limiting control manner realized by means of a mechanical structure is abandoned, and the planting depth of the transplanter can be changed through setting of digital parameters.
Description
technical field [0001] The invention relates to the field of transplanting machinery, in particular to an automatic control device and control method for planting depth of a transplanting machine. Background technique [0002] Transplanting technology is indispensable in modern agriculture. Transplanting through seedling cultivation can improve the seedling growth rate and survival rate of seedlings, thereby increasing crop yield. The popularization of transplanting technology has promoted the development of transplanting machinery, and transplanting machine is mainly made up of operating parts such as seedling picking device, planter, seedling supporting mechanism, ditch opener, covering soil suppressing device at present. In the transplanting operation, the evaluation indicators for the completion of the operation mainly include the rate of seedling establishment, planting depth, and planting speed. Among them, the planting depth index affects the slow seedling cycle and ...
