Wheat rotary tillage combined seed and fertilizer drill

Abstract

The invention discloses a wheat rotary tillage combined seed and fertilizer drill which comprises a rack, a rotary blade, a fertilizing mechanism, a sowing mechanism and a land wheel suppression mechanism, wherein the fertilizing mechanism comprises a fertilizer box and a fertilizer discharge pipe; the sowing mechanism comprises a seed box, a seeding mechanism and a sowing boot; the fertilizer box is located right above the rotary blade and fixed on the rack; the fertilizer discharge pipe is arranged in front of the rotary blade; the sowing boot is arranged behind the rotary blade; an adjustable soil guide plate is arranged behind the sowing boot; and the soil guide plate is fixed on the rack. According to the wheat rotary tillage combined seed and fertilizer drill disclosed by the invention, the overall structure is relatively compact; a sowing sequence of fertilizing, rotary tillaging, sowing, earthing and pressing is formed by improving the agricultural technology; chemical fertilizer and soil can be uniformly mixed to improve the fertilizer efficiency; the rotary blade backwards throws a mixture of crushed straws and the soil at a high speed; and when meeting the soil guide plate, the back-thrown mixture falls back to the land surface along the soil guide plate and covers wheat seeds to realize the aim of soil moisture conservation and water conservation.

Description

technical field [0001] The invention relates to a rotary tillage fertilization seeder, in particular to a wheat rotary tillage fertilization seeder capable of saving water and moisture. Background technique [0002] Now in my country's Huanghuaihai summer sowing area, wheat sowing is generally carried out after corn stalks are crushed and returned to the field to carry out wheat rotary tillage sowing. The basic structure of the current rotary tillage and fertilization seeder is as follows: it is composed of a rotary tiller and a seeding and fertilizing machine. A group of first ditch openers and a group of second ditch openers are arranged on the frame of the sowing and fertilizing machine. The furrower is adjacent to the rotary tiller of the rotary tiller and connected to the seed box of the seeder, the second furrower is adjacent to the pressing wheel of the seeding and fertilizing machine, and the first furrower and the second furrower are both The chisel opener, or the ...

Problems solved by technology

[0003] 1. Due to the limitation of the soil depth of rotary tillage, the content of corn stalks in the soil is high, causing the lower roots of wheat seedlings to be in the mixed layer of straw and soil after emergence. During winter, due to the good air permeability of the mixed layer, wheat roots are easy to be frozen to death resulting in dead seedlings

[0004] 2. Ditch fertilization with chemical fertilizers. Straw that is
