Abstract
The patent of the utility model relates to a corn drill's compaction wheel belongs to mechanical design and manufacturing field. The whole compaction wheel is in a shape of a nearly cylinder, the middle section of the outer surface of the compaction wheel is sunken in an arc shape, cylindrical surfaces at two ends of the surface are designed in a linear mode, and the edges of the end surfaces are chamfered; the middle part of the compaction wheel is provided with a big hole for fixing a bearing, and a small hole for placing a fixed shaft. By adopting the technical scheme, the compaction wheel is easy to design and manufacture, and the germination rate of the corn after sowing can be ensured.
Description
Technical Field
The patent of the utility model relates to a corn drill's compaction wheel belongs to mechanical design and manufacturing field.
Background
Corn is one of the main crops in China, the main agricultural steps are ditching, sowing, fertilizing, compacting and the like, and the complex agricultural process has increasingly strict requirements on cultivation equipment. With the development of science and technology, many types of corn seeders appear at home and abroad, most corn seeders have the functions of seeding, fertilizing, watering, covering soil, loosening soil, compacting and the like, but the design of a compacting wheel is basically designed in a traditional way when the corn seeder is used and found by looking up data summary, and the wheel is cylindrical. Although the cylindrical wheels can better compact the soil and have even stress, researches show that the germination rate of the corn after sowing is influenced to a certain extent.
Disclosure of Invention
In order to better solve the problem of the germination rate of the sowed corn, the compaction wheel is properly improved and designed. The utility model provides a simple structure, the compaction wheel of easily making uses the seeder of improving back compaction wheel through experimental study discovery, and the budding rate after the seeding obviously than improving preceding improvement.
Therefore, the utility model adopts the technical scheme that: the whole compaction wheel is in a shape of a nearly cylinder, the middle section of the outer surface of the compaction wheel is sunken into an arc shape, cylindrical surfaces at two ends of the surface are designed in a linear mode, and the edges of the end surfaces are chamfered; the middle part of the compaction wheel is provided with a big hole for fixing a bearing, and a small hole for placing a fixed shaft.
The utility model has the advantages that: adopt the utility model discloses a compaction wheel of technical design can guarantee the germination percentage after the maize seeding.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1 is an arc-shaped concave surface, 2 is a cylindrical surface, 3 is a shaft placing hole, and 4 is a bearing fixing hole.
Detailed Description
The utility model has the advantages that the whole compaction wheel is in a shape of a nearly cylinder, the middle section 1 of the outer surface of the compaction wheel is sunken into a circular arc shape, the cylindrical surfaces 2 at the two ends of the surface adopt a linear design, and the end surface edges are chamfered; the middle part of the compaction wheel is provided with a big hole 4 for fixing a bearing on the outer side, and a small hole 3 for placing a fixed shaft on the inner side.
The utility model has the advantages that: adopt the utility model discloses a compaction wheel of technical design, compaction wheel bear the most weight of seeding machine at during operation both ends face of cylinder 2, and 1 bearing capacity of middle circular-arc depressed face is less relatively, is unlikely to soil above the maize seed to be pressed too real when the compaction, therefore can guarantee the germination percentage after the maize seeding.
