Wheat sowing and fertilizer applying machine

Abstract

The invention belongs to the technical field of wheat sowing and fertilizer applying machines and discloses a wheat sowing and fertilizer applying machine. The wheat sowing and fertilizer applying machine is mainly and technically characterized by comprising a frame body, a fertilizer box and a seed box are arranged on the frame body, fertilizer guiding pipes are arranged below the fertilizer box, seed guiding pipes are arranged below the seed box, fertilizer applying drill legs are arranged in the front portion of the frame body, the fertilizer applying guide pipes are arranged behind the fertilizer applying drill legs, and the lower ends of the fertilizer guiding pipes are inserted into the fertilizer applying guide pipes. Sowing drill legs with the lower ends provided with sowing guide pipes are arranged behind the fertilizer applying drill legs, and the lower ends of the seed guiding pipes are inserted into the sowing guide pipes. A first straw paving mechanism is arranged between the sowing drill legs and the fertilizer applying drill legs, and a second straw paving mechanism is arranged behind the sowing drill legs. Fertilizer applying and sowing are completed through the drill legs, nearly all straw is spread on the surface of the soil, soil hardening is avoided, and the production cost is reduced; fertilizer is centralized, fertilizer waste is avoided, and the damage such as seedling burning caused when seeds fall onto the fertilizer is avoided.

Description

technical field [0001] The invention belongs to the technical field of wheat seeding machine accessories, in particular to a wheat seeding and fertilizing machine. Background technique [0002] At present, after the corn is harvested, in order to avoid burning the stalks and increase soil fertilizer, the corn stalks are crushed and returned to the field. The existing wheat planter adopts the rotary tillage sowing method, and a fertilizer guide pipe is arranged in front of the rotary tiller, and the soil is rotated with the rotation of the rotary tiller, and then a seed guide tube is arranged at the rear of the rotary tiller to feed the wheat. Seeds are sown. The above method has the following defects: one, the fertilizer is rotary tilled by the rotary tiller, and the fertilizer exists in various layers of the soil layer. When the wheat seeds fall on the fertilizer, it will cause burning and reduce the emergence rate; Layers and basically evenly distributed at all levels, t...

AI Technical Summary

Problems solved by technology

The above method has the following defects: one, the fertilizer is rotary tilled by the rotary tiller, and the fertilizer exists in various layers of the soil layer. When the wheat seeds fall on the fertilizer, it will cause burning and reduce the emergence rate; Layers and basically evenly distributed at all levels, the fertilizer is not concentrated, and it is far away from causing waste of fertilizer; Third, during the rotary tillage process of the rotary tiller, straws are present at all levels, and when wheat seeds fall on the straws, it will affect the germination of the seeds. rate, and the air permeability of the soil is high, which is not conducive to moisture conservation; Fourth, the stalks are rotated to the ground, causing serious soil water loss, and the sun directly shines on the ground, causing serious water evaporation
