Compacting device for a seeder

Abstract

The invention discloses a compacting apparatus of a seeder. The apparatus comprises a frame, bearing bars are fixedly installed at the bottom of double sides of the frame, shavers are installed at thebottom of the frame through a mounting rack, several fixed orifices are arranged at the side surface of the bearing bars, T shaped grooves are arranged in the bearing bars, rhombic bearings are internally inserted in the T shaped groove, and circular holes are arranged near left and right corners of the rhombic bearing; the rhombic bearing is internally inserted with rollers, the outside of the rollers is fixedly provided with a rolling wheel, several the rolling fingers are uniformly installed on the rolling wheel, and several triangular blocks are uniformly arranged on the external surfaceof the rolling fingers; the shavers comprise groove shavers and rolling finger shavers. Bearing height can be adjusted by fixed orifices of different heights, cost is saved, and universality is wider;by means of design of the rolling fingers and installation of triangular blocks, when the compacting apparatus compacts broken soil, large soil mass can be broken, cereal is easy to grow, soil attached to the side surface of the rolling wheels can be rejected by the shavers, so that working efficiency and working quality of the compacting apparatus can be guaranteed.

Description

technical field [0001] The invention relates to the field of seeder technology, in particular to a compacting device for a seeder. Background technique [0002] During the sowing process, farmers need to dig ditches first, then sow the seeds into the dug ditches, and then bury the sown seeds with soil. The operation process is very cumbersome and inefficient. However, the existing mechanical seeder integrates the functions of turning the soil, sowing, fertilizing, covering the soil and compacting, which is more convenient and efficient. A planter is a planting machine that uses crop seeds as the object of sowing. It is used for a certain type or a certain type of crop. It is often named after the name of the crop type, such as grain drill, corn hole sower, cotton seeder, pasture spreader, etc. According to the sowing method, it can also be divided into spreaders, drills, hole sowers, precision seeders, combined operation machines and no-tillage seeders, but no matter how th...

Problems solved by technology

[0004] (1) When the rollers of the seeder compaction device compact the soil, the height cannot be adjusted, and the compaction force is always single. Therefore, it is only suitable for compacting soil on some land and some grains, and the applicability is too narrow. If different land or different grains Changing different rollers to compact the land will increase the agricultural power and increase the cost, which is not cost-effective;

[0005] (2) The compaction devices of most of the current planters use smooth rollers to compact the soil-covered area, but the uncovered area will also be compacted, which not only consumes excess electric energy, but also slows down the compaction of the compaction device. It is difficult to crush the large soil when the smooth side of the roller presses the large soil, and in most cases, the roller directly presses the large soil into the soil-covered area, making it difficult for the seeds to grow and break the soil after rooting and germination. Difficult consequences, reducing the seeding survival rate of the planter;

[0006] (3) The compacting device of the general seeder is good for compacting hard and non-sticky soil. When the compacting device compacts wet or sticky soil, the side of the roller will be stained with soil, and the weight of the compacting device will increase. As a result, the compaction device will roll and compact the land slowly, and the compaction efficiency and quality will decrease, which will have a negative impact on the future growth of seeds
