Adaptive multi-frequency ultrasonic-vibration low-resistance wear-resistance subsoiler and operation method thereof

Abstract

The invention provides an adaptive multi-frequency ultrasonic-vibration low-resistance wear-resistance subsoiler and an operation method thereof. The adaptive multi-frequency ultrasonic-vibration low-resistance wear-resistance subsoiler comprises a frame, a subsoiling soil-preparation device and an ultrasonic vibration device. The frame is used for supporting and fixing the subsoiling soil-preparation device and the ultrasonic vibration device and is connected with a tractor suspension system; the subsoiling soil-preparation device is used for work of subsoiling and soil preparation, surface soil block breaking and compacting; the ultrasonic vibration device is used for generating ultrasonic waves and converting the same into high-frequency mechanical vibration for the subsoiling operationparts so as to realize ultrasonic vibration operation of the subsoiler. By means of ultrasonic-vibration resistance reducing, the subsoiler needs low power as compared with the conventional subsoilerduring operation; with the adaptive multi-frequency ultrasonic vibration working mode, the subsoiler is adaptable to different work environments; adhesion and resistance are both reduced by means ofultrasonic vibration on the shovel surface, the problem of severe wear to the subsoiler during operation can be solved, and accordingly, dependency to import parts is reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and relates to a self-adaptive multi-frequency ultrasonic vibration low-resistance subsoiler and a method, which realize subsoiling operations while reducing operation resistance and improving the service life of a subsoiling shovel. technical background [0002] At present, subsoiling technology is an important method of conservation tillage. Subsoiling operation is conducive to improving the soil's ability to store water and moisture, and create good conditions for crop growth and root penetration. Loose soil is conducive to the infiltration of rainwater and increases the water storage capacity of the soil field. Therefore, subsoiling operation has important practical significance for improving crop yield and quality; [0003] On the one hand, due to the large resistance during the subsoiling operation, a high-power tractor is required for traction to provide power. High-power tr...

Problems solved by technology

[0006] After searching the literature of the existing technology, it was found that the Chinese invention patent "a vibrating subsoiler" patent application number 201620213914.0 uses a tractor power output shaft directly connected to mechanical vibration components such as a reducer to perform low-frequency vibration on the subsoiler , low-frequency vibration has a general effect on reducing viscosity and drag, while mechanical vibration reduces traction resistance, but the energy consumption of the tractor increases a lot

Chinese invention patent "Bionic drag-reducing deep loose shovel handle based on power function curve" patent application number 201310756322.4 uses bionics to imitate the surface contour of brown bear claws and toes, and its shape has a power function curve form, but it is not suitable for animals' active planing, digging, Actions such as soil movement are not imitated, only the contour curves of animals are imitated, so it belongs to passive drag reduction. At the same time, no key research has been carried out on the wear of key components of the subsoiler; existing subsoilers mostly use passive bionics to reduce drag. Resistance or low-frequency vibration drag reduction, did not solve the problems of large subsoiling resistance, easy wear of key components, and low service life, which led to the unpopularity of domestic field subsoiling operations
