METHOD OF SURFACE IMPROVEMENT OF GETTING HILLOCK MEADOWS AND PASTURES AND DEVICE FOR ITS IMPLEMENTATION

摘要

FIELD: agriculture.;SUBSTANCE: method includes the undercut of bases and simultaneous milling of vegetative and ground knolls. In addition a turfy layer is cut and milled, and undercut of bases of knolls and turfy layer is performed to the depth 5 cm from the soil surface on the width strip 1.2 m. After that the milled particles of knolls and turfy layer are separated into fine particles with the size no more than 5 cm and into coarse particles, with the size above 5 cm, with laying of fine particles above coarse ones, and grading of the soil surface. Grass seeds are sown to the depth 1-1.5 cm with application of starting dose of mineral fertilizings and after-sown rolling down, leaving unsown 10 cm edge strips along the strip to be sawn. The device includes the vertical milling drums installed on the basic frame at equal intermediate space with a possibility of rotation. The working members of milling drums are designed with the shape of spherical disks with shaped cuts with a cutting edge as convex curve along their edge, milling drums installed on shafts layer-by-layer equally spaced, and with a convex surface facing towards the basic frame. Meanwhile the basic frame is installed at the angle to the direction of the machine motion, ensuring overlapping of trajectories of motion of spherical disks. In addition, the device is equipped with series-installed raking grating and sowing section with raning roller behind the milling drums on the additional frame. Meanwhile the additional frame is rigidly connected with basic one and is installed towards the machine motion. Besides, the raking grating, teeth of which are installed with equal spacing interval 5 cm, is connected articulately to the additional frame, and milling drums are installed on the basic frame with a possibility of rotation towards each other.;EFFECT: inventions allow to increase productivity of meadows and pastures.;2 cl, 5 dwg
