Compound operating machine for band seeding of brassica napus rotary tillage, ditching and fertilizing clean area

Abstract

The invention discloses a compound operating machine for band seeding of a brassica napus rotary tillage, ditching and fertilizing clean area. The compound operating machine comprises a rack and grassdividers, a rotary tillage device, furrow openers and press wheels which are connected to the rack in sequence from front to rear, wherein the rack is also provided with a fertilizer can and seed boxes, a plurality of fertilizer discharging devices are arranged under the fertilizer can, the lower portions of the fertilizer discharging devices are connected with fertilizer discharging sliding ways, seeders are arranged under the seed boxes, and the lower portions of the seeders are connected with seeding pipes; each grass divider comprises two grass dividing wheels, the edges of every two grass dividing wheels are provided with outward inclined grass dividing teeth. Each grass divider also comprises a grass divider wheel fork and a wheel seat, wherein one end of each grass divider wheel fork is hinged to the rack, the other end of the corresponding grass divider wheel fork is connected to the corresponding wheel seat, each wheel seat is connected with the corresponding two grass divider wheels, and every two grass divider wheels are inclined to the direction opposite to the horizontal plane. The compound operating machine for band seeding of the brassica napus rotary tillage, ditching and fertilizing clean area integrates grass dividing, band rotary tillage, drainage ditch digging, fertilizing, seeding in the clean area and suppression, can clear up straw on a field seeding zone through the grass divider, avoids the effect of the field straw on normal seeding, and reduces the soil disturbance only through rotary tillage on the seeding zone.

Description

technical field [0001] The invention relates to a compound operation machine for belt-shaped sowing of rapeseed rotary tillage, ditching, fertilization, and clean area, and belongs to the technical field of rapeseed seeders. Background technique [0002] At present, most foreign seeders are suitable for large-scale farms, which require relatively high land flatness. They are generally large-scale machines and are expensive. Domestic seeders are mostly small machines that can meet the requirements of sowing. The price is relatively low, but the function is single. , the sowing rate is uneven, the operation effect is poor, and the rapeseed yield is low, which cannot meet the development requirements of agricultural mechanization in my country. The accuracy of the sowing rate of the existing seeder is not high, and the function is single, which leads to complicated production process and high production cost for farmers. On the other hand, the current harvesting process of agri...

[0002] At present, most foreign seeders are suitable for large-scale farms, which require relatively high land flatness. They are generally large-scale machines and are expensive. Domestic seeders are mostly small machines that can meet the requirements of sowing. The price is relatively low, but the function is single. , the sowing rate is uneven, the operation effect is poor, and the rapeseed yield is low, which cannot meet the development requirements of agricultural mechanization in my country

The accuracy of the seeding rate of the existing seeder is not high, and the function is single, resulting in a complicated production process and high production costs for farmers

On the other hand, the current harvesting process of agricultural products basically uses large-scale machinery, and the waste straw after harvesting is basically discarded in the field. These waste straw can be used as fertilizer, but because the waste straw is evenly spread in the field, the amount of straw It will affect the sowing of rapeseed, especially when working in rice stubble fields. Due to the characteristics of large amount of straw and high soil moisture content in this kind of field, it is difficult to guarantee the operation quality of general machinery and tools.
