Feeding control system for automatic transplanter and its control method

Abstract

The invention provides an automatic transplantation machine taking and feeding control system and a control method thereof. The automatic transplantation machine taking and feeding control system comprises a transplantation disk control system, a seedling taking control system, a seedling feeding control system and a programmable controller, wherein two main power sources such as a stepping motor and a chassis engine are used, the chassis power source is respectively transferred to a transplantation duckbill and a seedling separation rotation cup while an inflation pump is connected to supply a gas source for a gas cylinder, the movement coordination among various parts is achieved only with five sensors and an encoder, and the operation interface is designed in a touch screen manner and real-time monitoring and alarming can be achieved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery automation, and in particular relates to a fetching and feeding control system for an automatic transplanting machine and a control method thereof. Background technique [0002] Transplanting can shorten the growth process of crops, improve the disaster and drought resistance of crops, reduce the need for secondary replanting, increase the growth cycle of crops, and improve crop yield and quality. my country's transplanting machines have broad market prospects. The officially announced "2012-2014 Catalog of Agricultural Machinery Products Supported and Promoted by the State" shows that there are 27 varieties of transplanting machines and 12 companies included in the catalogue. Semi-automatic transplanting machines are the main ones, with low transplanting efficiency and heavy manual workload, so time-saving and labor-saving fully automatic transplanting is the main direction for the developmen...

my country's transplanting machines have broad market prospects. The officially announced "2012-2014 Catalog of Agricultural Machinery Products Supported and Promoted by the State" shows that there are 27 varieties of transplanting machines and 12 companies included in the catalogue. Semi-automatic transplanting machines are the main ones, with low transplanting efficiency and heavy manual workload. Therefore, time-saving and labor-saving fully automatic transplanting is the main direction for the development of transplanting machines in the future.

[0003] Patent CN104737686A discloses a motion coordination control system and control method for automatic transplanting machine for plug seedlings. Through the combination of PLC and relay, the coordinated control of the action of the transplanting machine is realized by using the relay on and off. The disk mechanism takes up a lot of space and is not suitable for greenhouse operations, and the transplanting efficiency is limited

CN104808573A discloses a transplanting machine control system, which uses a motor lead screw combined with a variety of position sensors to realize the entire transplanting process, but the system uses 6 stepping motors with too much power, the cost of the control system is high, and the control process is complicated

CN103294058A discloses a robot transplanting control system and control method for column cultivation, which is only suitable for indoor flower transplanting, seedling filling and bad removal operations
