Self-excited vibration drag-reduction intertillage hiller

Abstract

The invention relates to a self-excited vibration drag-reduction intertillage hiller, and belongs to the field of agricultural machinery. The hiller comprises a shovel tip, a shovel chest, a connecting plate, a fixing plate, a shovel handle, a hilling plate, a positioning block and a self-excited vibration device, wherein the fixing plate is arranged in the middle of the shovel handle; the hillingplate is installed on the fixing plate; the connecting plate is hinged to the shovel handle below the fixing plate; the positioning block is installed at the lower end of the shovel handle; the shovel tip is connected with the self-excited vibration device capable of driving the shovel tip to vibrate; the self-excited vibration device is hinged to the positioning block; and the shovel chest is arranged on the upper end face of the shovel tip. During intertillage hilling, the interaction force between the self-excited vibration device and the shovel tip is continuously changed, so that the shovel tip vibrates within a certain range, more favorable cutting conditions and a more favorable stress state for soil crushing are generated, self-excited vibration can be generated without applying additional exciting force, the tillage resistance in the intertillage hilling operation process is effectively reduced, the power consumption in the intertillage hilling process is reduced, and the effects of saving energy and protecting the environment are achieved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a self-excited vibration and drag-reducing cultivator for cultivating soil. Background technique [0002] As an important part of agricultural production, cultivating has always been valued by the working people. Ridging cultivation has the advantages of increasing the ground temperature, increasing the air permeability of the root system, and making the root system survive in the fertile living soil layer, which greatly promotes the increase of crop production, and is also conducive to timely drainage after rain in the field to prevent rot. and the occurrence of epidemics, so it has been widely used. Many crops cultivated by ridges require intertillage and weeding and heightening ridges in the middle stage of growth and development to achieve the purpose of water storage and moisture conservation. The application of intertillage soil cultivators greatly reduces...

Problems solved by technology

Because it is located in a mountainous area, the popularization and application of large tractors and large agricultural machinery is limited

Especially for some mountainous areas where the soil is clay-heavy soil, this kind of soil shows different properties due to its different moisture content: when the moisture content is high, the soil viscosity increases, and it is easy to produce back-up soil, which makes the adhesion of the earth-building parts Increase; when the soil moisture content is low, it is easy to agglomerate, and the resistance of broken soil increases, which increases the power consumption of cultivating soil
