Vibrating type harvesting machinery for lotus roots and intelligent control method of harvesting machinery

Abstract

The invention provides vibrating type harvesting machinery for lotus roots and an intelligent control method of the harvesting machinery. The machinery includes hydraulic cylinders I, a lifting platform, a leakage sieve, a machine frame, a rotating hairbrush, a gearbox, a hydraulic motor, a pulley mechanism, and a crank double-rocker mechanism. According to the machinery provided by the invention,a tractor is used to provide power, the machinery is installed at the front end of the tractor, the rotating hairbrush is utilized to remove mud at the surface of the lotus roots, deep mud of the lotus roots is loosened by the leakage sieve, and therefore the lotus roots without sludge are floated out of the water surface. The intelligent control method of the harvesting machinery relies on a pressure sensor to detect the pressure change of brushing of the rotating hairbrush at the surface layer of the lotus roots in real time to realize self adaptive adjustment of the height of the hairbrush; and at the same time, the method relies on a revolution speed sensor to detect the revolution speeds of the hydraulic motor and a power plant engine in real time to realize the self adaptive adjustment of the revolution speeds. The machinery provided by the invention is widely applied to excavation of the lotus roots in an artificial lotus root field, and can realize the effects of saving costsand increasing benefits; and the promotion and application of the machinery promote the ''quality'' leap of a lotus root excavation manner, thereby driving the lotus root production and processing industries, and promoting the agricultural industry structure adjustment.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery automation, and in particular relates to a machine intelligent control method for a vibrating lotus root harvester. Background technique [0002] Lotus root is a characteristic agricultural product with good economic benefits and high edible value. With the adjustment of the agricultural industrial structure, the planting area of ​​lotus root in my country has been continuously expanding, exceeding more than 60 million mu. However, lotus root is also an agricultural product that is easy to grow and difficult to harvest. Currently, its excavation method mainly relies on manual labor, which not only has high labor intensity and harsh working environment, but also has a low digging rate and serious damage to the lotus root, which restricts the development of the lotus root industry. [0003] At present, most domestic lotus root harvesting machines use high-pressure water jet harvester...

AI Technical Summary

Problems solved by technology

However, the existing lotus root digging machines have the following problems: 1) High-pressure water guns are used for repeated washing, resulting in high energy consumption and long working hours; 2) Workers need to work underwater and the high-pressure water guns are difficult to control, resulting in high labor intensity and high technical requirements; 3) The underwater environment is complex, and the water circulation and filtration system fails frequently
