Rotary tillage seeder

Abstract

The rotary tillage seeder comprises a walking support, a rotary tillage cutter shaft, a press wheel, rotary tillage cutters, a seeding box, a fertilization box, a transmission device and a core ploughshare, the multiple rotary tillage cutters are arranged on the rotary tillage cutter shaft in pairs, and the two rotary tillage cutters in each group are symmetrically arranged; the plurality of core ploughshares and the plurality of fertilizer discharging pipes on the fertilizer applying box are respectively arranged along the axial direction parallel to the rotary tillage cutter shaft, and are positioned at the central symmetry positions corresponding to the rotary tillage cutter group; a plurality of seed-metering pipes on the seeding box are arranged in pairs and are arranged at equal intervals in a manner that the central symmetry positions of the seed-metering pipes are consistent with the central symmetry positions of the rotary blade groups. The row-to-row rotary tillage device has the advantages that the rotary tillage blades of the row-to-row rotary tillage device are only arranged at the narrow-distance positions of the adjacent seed-metering pipes of the seeder, power consumption is reduced, soil corresponding to the wide-distance positions of the adjacent seed-metering pipes of the seeder is not subjected to rotary tillage during operation of the seeder, and the purpose of protective tillage can be achieved; wide-narrow row alternation and plant position staggering of wheat seedlings are formed after sowing, and ventilation and light transmission of wheat are facilitated.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a wide and narrow row rotary tillage seeder with side deep fertilization. Background technique [0002] Although the current wheat compound operation machine has functions such as ditching, leveling, sowing, and suppression, the operation effect is equal row spacing, which makes the wheat plants poorly ventilated and light-transmitting, which affects the wheat yield; and the fields between the rows where no wheat is planted are also plowed. , which consumes more work power, and is not conducive to field fertilizer storage; at the same time, this kind of operating machine must cooperate with a fertilizer spreader or artificial fertilizer, and manual fertilizer needs to cooperate with the mechanical soil preparation process to implement it well. Therefore, this operation method of separating seeding and fertilization makes it impossible for the fertilizer to be accur...

Problems solved by technology

[0002] Although the current wheat compound operation machine has functions such as ditching, leveling, sowing, and suppression, the operation effect is equal row spacing, which makes the wheat plants poorly ventilated and light-transmitting, which affects the wheat yield; and the fields between the rows where no wheat is planted are also plowed. , which consumes more operating power, and is not conducive to field fertilizer storage; at the same time, this kind of operating machine also needs to cooperate with a fertilizer spreader or artificial fertilizer, and manual fertilizer needs to cooperate with the mechanical soil preparation process to implement it well

Therefore, this kind of operation method of sowing and fertilizing separately prevents the fertilizer from being accurately and evenly distributed in the sowing area, causing serious waste and loss, and the fertilizer layer is chaotic and the amount of fertilizer at the bottom is small.
