Straw-mulching stubble-cleaning ditching seeding machine

Abstract

The invention discloses a straw-mulching stubble-cleaning ditching seeding machine. On the basis of a using direction, the straw-mulching stubble-cleaning ditching seeding machine comprises a first roller and a second roller, which are arranged in tandem, and a seeder, wherein a housing baffle is arranged above the first roller and the second roller; a flow distribution plate is arranged between the second roller and the housing baffle; a smashed straw flow channel is formed between the flow distribution plate and the housing baffle; a first knife roll group is arranged on the first roller; a second knife roll group and a plurality of ditching knives are arranged on the second roller; the seeder comprises a plurality of seed dropping pipes; and outlets of the seed dropping pipes are formed on the rear upper part of the second roller. According to the straw-mulching stubble-cleaning ditching seeding machine, straw smashing, straw cleaning, shallow rotation stubble cleaning, seed drilling, straw mulching, ditching, earth covering and seed covering can be accomplished in one-time operation. Straws can be effectively separated from soil cultivation, and soil incompactness caused by a large number of straws within the soil can be prevented, so seeds can be sown in the soil with a good structure, seed sowing quality and the rate of emergence are improved. The straw-mulching stubble-cleaning ditching seeding machine can be applied to modeled cultivation and is comprehensive and wide in popularization prospect.

Description

technical field [0001] The invention relates to a compound operation machine for farmland operations, in particular to a straw-covered stubble-cleaning ditching seeder, which is especially suitable for straw returning to the field with less and no-tillage planting, and can complete straw cleaning, surface stubble clearing, Seeding, straw mulching, ditching and soil covering seeds. Background technique [0002] With the acceleration of the construction of a well-off society in our country, the advancement of urbanization has allowed a large number of farmers to go to towns and cities, the improvement of the level of agriculture, rural areas and farmers, the era of liquefaction of farmers' living fuel, and the use of a large amount of straw from agricultural production for farmers' fuel has passed. Gone forever, a large amount of straw has become agricultural waste that is difficult to deal with. In recent years, a large number of straw burnings have caused flight delays, hig...

Problems solved by technology

On the one hand, this sowing method causes an increase in the amount of seed used for sowing. In some places, the amount of seed used per mu of wheat is as high as 40 kg, and the emergence rate is extremely low, resulting in a waste of seed; on the other hand, it is easy to cause wheat seeds to be of different depths in the soil. , resulting in uneven seedling emergence, uneven density, and a serious decline in population quality, which affects field ventilation and lighting in the later stage of wheat growth, and easily induces sheath blight, powdery mildew, scab and late lodging

In addition, this sowing method plows all the straw into the soil, and a large amount of straw is mixed with the soil, causing the soil to become empty. Competing with the seedlings for nitrogen fertilizer, resulting in nitrogen deficiency and malnutrition at the seedling stage, increasing the difficulty of field management, making it difficult to ensure high and stable yields, which directly restricts the further increase of wheat yields; and this sowing method is not suitable for model cultivation and cannot be fully promoted
