Copying precision sowing top dressing machine

Abstract

Belonging to the field of agricultural machinery, the invention relates to a copying non-tillage precision sowing top dressing machine, which consists of: a main frame, road wheels, a ditching device,a seed metering (fertilizer) box, a transmission mechanism and a press device. The sowing machine adopts suspended operation, not only can be used for sowing wheat and soybeans, but also can be usedfor fertilization operation during a crop seedling stage. The seed metering devices of the sowing machine are powered by ground wheels, and the seed metering (fertilizer feeding) amount can be adjustable. The ditching device and the soil covering press device both have copying function, the ditching device can adjust the ditching depth of a ditch opener according to the terrain during work, and ensure the ditching stability so as to meet the precise operation requirement. In addition, components on the sowing machine are mostly fixed by U-shaped wires, thus being convenient for adjustment of the line spacing of sowing (fertilization) operation, and also being convenient for installation and later maintenance. The copying non-tillage precision sowing top dressing machine provided by the invention realizes the sowing requirements of operation on uneven soil, and has the advantages of consistent sowing depth, high efficiency, multiple purposes, strong adaptability and the like.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and relates to an imitation form precision no-tillage sowing and topdressing machine. Background technique [0002] The seeder is one of the commonly used machines in agricultural production, and there are still many deficiencies in the existing traditional seeder in China. For example: when the existing sowing works on uneven ground, it is difficult to ensure the stability of ditching due to the large undulations of the ground, resulting in inconsistent sowing depths, thereby affecting the uniformity of seedling emergence; The amount of seeds cannot be adjusted, and one machine can not be used for multiple purposes, and it has been difficult to meet the needs of farmers. Therefore, there is an urgent need for a seeder that is multifunctional and capable of working on uneven ground. Contents of the invention [0003] The object of the present invention overcomes above-mentioned weak point...
