Description
Technical Field
The invention relates to the technical field of seeders, in particular to a compaction device of a seeder.
Background
In the sowing process, farmers need to dig a ditch first, then sow the seeds into the dug ditch, and then bury the sown seeds with soil, so the operation process is very complicated and the efficiency is low. The existing mechanical seeder integrates the functions of soil turning, seeding, fertilizing, soil covering and compacting, is convenient and efficient. The sowing machine is a planting machine using crop seeds as sowing objects, is used for sowing a certain type or a certain type of crops, is usually named by crop types, such as a grain drill, a corn hill planter, a cotton sowing machine, a pasture grass sowing machine and the like, and can be divided into a sowing machine, a drill, a hill planter, a precision sowing machine, a combined operation machine and a no-tillage sowing machine according to a sowing method, but the sowing flow of the sowing machine is basically unchanged no matter how the sowing is classified. The soil compaction, the final step of the seeding machine, is the most important step in the seeding step, and the soil compaction has different effects on the growth of the grains, namely, the soil compaction is not good or tight, so that the quality of the compaction device of the seeding machine is not small and variable.
The compaction devices of the sowing machines currently on the market have the following disadvantages and problems:
(1) when the roller of the seeder compacting device compacts soil, the height cannot be adjusted, and the compacting force is always single, so that the seeder compacting device is only suitable for compacting soil of partial soil and partial grains, the applicability is too narrow, if different soil or different grains are replaced by different rollers to compact the soil, the agricultural power is increased, the cost is increased, and the cost is not high;
(2) the compaction device of most existing seeders compacts an earth covering area by a roller with smooth side surface, but the area without earth covering can be compacted, thereby not only wasting redundant electric energy, but also slowing down the compaction speed of the compaction device, and when the large soil block is compacted by the smooth roller side surface, the large soil block is difficult to crush, and most of the conditions are that the roller directly presses the large soil block into the earth covering area, thereby causing the results of difficult seed growth and difficult ground breaking after rooting and germination, and reducing the seeding survival rate of the seeder;
(3) the compaction device of the general seeder can well press hard non-sticky soil, when the compaction device compacts wet or sticky soil, the side surface of the roller is stained with soil, the weight of the compaction device is increased, and the pressing force is reduced, so that the compaction device slowly rolls and compacts the soil, the compaction efficiency and the compaction quality are reduced, and the later growth of seeds is adversely affected.
