Crop inter-plant automatic weeding mechanism

Abstract

The invention discloses a crop inter-plant automatic weeding mechanism, and belongs to agricultural machinery. The crop inter-plant automatic weeding mechanism is characterized in that a sun gear is fixed on a power input shaft, a friction ring with a driving shaft is assembled outside the upper side of the sun gear, a planetary gear, a bevel gear A and a hanging frame are installed on the driving shaft, a middle shaft and a driven shaft are installed on the hanging frame, bevel gears B and C are fixedly installed on the middle shaft, a bevel gear D and a cutter head are fixedly installed on the driven shaft, a weeding cutter is fixedly installed on the cutter head, the planetary gear is sleeved with an inner gear ring, a stepping motor provided with a connecting plate and a n-shaped friction frame is arranged above the friction ring and the inner gear ring, a housing provided with an ultrasonic sensor covers the sun gear, the friction ring and the inner gear ring, and an automatic controller communicates with the ultrasonic sensor and the stepping motor through wires correspondingly. The mechanism has the advantages of being novel, unique and reasonable in structure, high in inter-plant mechanical weeding efficiency, good in quality, low in seedling damage rate and high in automation degree.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a mechanical weeding mechanism. Background technique [0002] In recent years, with the development of green organic agriculture in China, the use of chemical herbicides has been decreasing year by year, and mechanical weeding machines without pollution and drug residues have become indispensable tools for weeding operations. However, due to the deficiencies in the structural design, when the current weeding machine is weeding the inter-row grass, its operating parts not only remove the inter-row grass, but also produce irregular mechanical scraping damage to the seedlings. Even its root system is dug out from the soil, causing the death of the plant seedlings, the rate of injury to the seedlings is higher, and the popularization and application of mechanical weeding tools is limited. Contents of the invention [0003] The purpose of the present invention is to solve the problems...

Problems solved by technology

However, due to the deficiencies in the structural design, when the current weeding machine is weeding the inter-row grass, its operating parts not only remove the inter-row grass, but also produce irregular mechanical scraping damage to the seedlings. Even its root system is dug out from the soil, causing the death of plants and seedlings, the rate of injury to seedlings is high, and the popularization and application of mechanical weeding tools is limited
