Seedling strip weeding single body for conducting ultrasonic ranging and automatically regulating weeding depth

Abstract

The invention discloses a seedling strip weeding single body for conducting ultrasonic ranging and automatically regulating weeding depth, and belongs to agricultural machinery. A mounting shelf is fixedly installed on a rack cross beam, a single body shelf is hinged to the mounting shelf through a parallel four-bar mechanism A, the two ends of a bothway hydraulic oil cylinder are hinged to the mounting shelf and the single body shelf respectively, an earth surface profiling slide plate assembly is hinged to the lower portion of the front end of the single body shelf through a parallel four-bar mechanism B, a ranging projection disc is horizontally and fixedly installed at the upper end face of the earth surface profiling slide plate assembly, an ultrasonic ranging sensor is installed at the portion, located above the ranging projection disc, on the single body shelf, a wire makes the ultrasonic ranging sensor communicated with a hydraulic system control single-chip microcomputer, and a weeding tooth disc wheel assembly is assembled at the portion, located at the rear part of the earth surface profiling slide plate assembly, of the lower lateral part of the rear end of the single body shelf. The seedling strip weeding single body makes weeding in-soil depths keep consistent all the time, and has the advantages of being novel and reasonable in structure, high in automated degree, good in work quality, and high in adaptability.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to an operation unit for automatically regulating the weeding depth of the seedling belt on a mechanical cultivating and weeding machine tool. Background technique [0002] In recent years, with the vigorous promotion and application of green organic agricultural technology, the use of herbicides has been greatly restricted. Therefore, the development and application of mechanical intertillage and weeding tools that are pollution-free and drug-free have received great attention, especially in many areas. In Heilongjiang, where there are few people and a high level of mechanized operations, mechanical intertillage and weeding have begun to be widely used, providing technical support for the production of green and organic agricultural products. However, due to the defects in the structural design, on the existing mechanical cultivating and weeding implements, the weeding toothed wheel a...

Problems solved by technology

However, due to the defects in the structural design, on the existing mechanical cultivating and weeding implements, the weeding toothed wheel assembly can be directly hinged on the frame, and the weeding toothed wheel assembly can be floated up and down. The direct support contact mode follows the shape of the ground. In actual operation, when the soil of the ridge is dry and stiff, the weeding tooth disc assembly is shallow into the soil, and the weeding effect is poor. When the soil of the ridge is soft or the water content is high, the depth of penetration large, high seedling injury rate, and even seedling embedding phenomenon, and the embedding rate is high, that is, the profiling effect of the existing structure is poor
