Description

Technical Field

[0001] The invention belongs to the field of agricultural machinery automation, and in particular relates to a control method for output of daylily picking equipment based on PLC output. Background Art

[0002] Daylily is an important economic crop in my country and belongs to the category of flower bud vegetables. The planting area in Wuzhong City, Ningxia Hui Autonomous Region is relatively large. Due to the concentrated flowering period, the daily amount of flowers harvested is huge. If the harvesting is not timely, the daylily will lose its commodity value after flowering. The growth state of the flower buds of the same daylily will also be different. When picking, the flower buds that have not reached the harvesting node cannot be destroyed. In addition, the rhizomes of daylily can grow for 8-10 years, so it is not possible to rely on the existing vegetable harvesting equipment for one-time harvesting and sorting. According to the survey, daylily picking is carried out from 4:00 to 8:30. Local growers will hire experienced workers to select and pick the buds and put them in the back cage. This picking operation is slow, the dew is heavy at night, the environment is harsh, and long-term standing, walking and weight-bearing are also very physically demanding for workers. In addition, the harvested daylily buds are weighed uniformly, and the specific yield of a certain production area cannot be obtained when picking.

[0003] In response to the first half of the problem, Shanxi Agricultural University designed a 4HF-6 daylily auxiliary harvester, which can simultaneously carry out 6-station daylily harvesting operations. It uses a crawler chassis with good maneuverability and improves the harvesting working environment. However, the prototype uses a hydraulic walking system, which has poor durability and reliability. In addition, the vibration of the machine is too large under this power mode, and the ride comfort is poor. In summary, the design of daylily picking machinery should be mainly to assist manual picking, and the power part needs to be improved. For growers, it is necessary to greatly improve the picking efficiency and monitor the yield of daylily in the travel area to facilitate the increase in production and income in the next year. Therefore, it is necessary to design a control method to intelligently output the daylily yield in the production area during the picking process. Summary of the invention

[0004] The present invention aims to solve at least one of the above technical problems to a certain extent. To this end, the present invention proposes a control method for outputting daylily picking equipment based on PLC, which controls the daylily auxiliary picking equipment to carry workers to steadily harvest daylily buds in the field during the working process through the PLC controller and the navigation module, and effectively outputs the daylily output per unit time or per unit area, and finally presents it intuitively in the form of a chart, thereby improving the picking efficiency and facilitating the monitoring of the daylily output in the traveling area.

[0005] Note that the description of these objectives does not prevent the existence of other objectives. One embodiment of the present invention does not need to achieve all of the above objectives.
