Embodiment Construction

[0026] Below in conjunction with accompanying drawing, the present invention will be further described:

[0027] This high-precision combined leveling method suitable for standard rice seedling sheds: through the combined leveling machine that integrates the square coulter 23, the rotary leveler and the suppression roller, the combined leveling machine is used to pull the combined leveling machine by a tractor. Combination of crushing-flat-pressing finishing process to complete the fine leveling base surface of seedling raising;

[0028] When leveling the base surface for seedling raising, the combined leveler moves forward with the tractor, first cuts the shallow surface soil layer through the square coulter 23 at the front end of the body frame 5, and then implements the rotary extrusion leveling operation by the rotary leveler, rolling the leveling roller 8 is driven by the power rotation of the central main shaft 38 and moves forward with the leveling machine. Under the ac...

Abstract

The invention relates to a high-precision combined leveling method suitable for a standard rice seedling raising shed. The high-precision combined leveling method comprises the following steps that firstly, a shallow surface soil layer is chopped through square coulters at the front end of a machine body frame, then rotary extrusion soil leveling operation is performed through a rotary leveler, and a rolling soil leveling roller is driven by power rotation of a central main shaft to move forwards along with the leveler; the surface soil layer of a seedling raising shed basal plane is subjected to the action of rotating thrust of the rolling soil leveling roller so that soil particles of the surface soil layer of a seedling raising shed basal plane form a planar spiral flowing effect, continuous circular surface uniform flattening is carried out, under the action of spiral surface friction, soil at the raised areas are evenly pushed to lower terrain positions, it is fully guaranteed that the rolling soil leveling roller repeatedly extrudes the surface soil, soil layer air elimination gaps are removed, and therefore the flatness and the compaction degree are improved; and finally, the leveled basal plane is pressed by a drum-type pressing machine at the rear part of the machine body frame, and the soil basal plane is forcibly pressed again to compact the ground surface. According to the high-precision combined leveling method, a crushing-flattening-pressing combined finishing process is realized, and the requirement of finely flattening the seedling raising basal plane is met at a time.

Description

Technical field: [0001] The invention relates to special finishing equipment for rice seedling production bases in the technical field of agricultural machinery, and specifically relates to a high-precision combined leveling method suitable for standard rice seedling raising sheds. Background technique: [0002] Promoting the overall mechanization of the whole process is the overall layout of my country's agricultural machinery development plan. There are still many weak links and blank areas in the development of agricultural mechanization in my country. It is necessary to develop high-efficiency intelligent agricultural equipment for the frontier of science and technology and the needs of international competition, but also to develop farmers' needs, advanced and applicable characteristic areas, and production and operation equipment for characteristic crops based on national conditions. It is necessary to develop large and medium-sized agricultural machinery as well as s...
