Rotary tillage broadcast sowing combined drill for wheat

Abstract

The invention provides a tilling and seeding combination seed drill for sowing wheat, and relates to the technical field of agricultural rotary-cultivating and sowing machines. The combination seed drill comprises a machine frame and a mounted frame, a gear box, a rotary tillage mechanism, and a seeding mechanism and a seed delivering mechanism thereof, and is characterized in that: two or more than two seed tubes are arranged transversely and at intervals; the seed tubes are connected with underground seed transverse and even casting devices below which are arranged behind rotary tilling blade shafts. The combination seed drill has the advantages of unique and reasonable structure, integrated operations of fertilization, rotary tillage, seeding, ridge raising, compression, etc. with a tractor, labor and time conservation, energy conservation, improved working efficiency, reduced labor intensity, high utilization rate of nutrition, water and manure in soil, basically even seeding, uniform seeding depth meeting requirement of seeds for germination, creation of good environment for seed germination, great improvement on the germination percent of the seeds, and improvement on the growth quality and total output of wheat.

Description

technical field [0001] The invention relates to the technical field of agricultural rotary tillage or seeding machinery. Background technique [0002] The existing wheat seeders are all ditch drills, the sowing belt is narrow, the emergence of seedlings is concentrated, the seedlings compete for nutrients, and the soil nutrients and water between the two ridges cannot be fully utilized. Moreover, prior to the operation of the existing seeder, it is necessary to plow with a rotary tiller and a soil preparation machine before sowing. The tractor needs to enter the field twice to complete the operation, which has high energy consumption, high cost and low operation efficiency. Ordinary wheat sowing equipment is relatively simple. The seeds are scattered on the surface before rotary tillage. When the rotary tillage is completed, the seeds are turned and buried in the ground with the soil.

Problems solved by technology

[0002] The existing wheat planters are all ditch-drill sowing, the sowing belt is narrow, the emergence of seedlings is concentrated, the seedlings compete for nutrients, and the soil nutrients and water between the two ridges cannot be fully utilized

Moreover, prior to the operation of the existing seeder, it is necessary to plow with a rotary tiller and a soil preparation machine before sowing. The tractor needs to enter the field twice to complete the operation, which has high energy consumption, high cost and low operation efficiency.

Ordinary wheat sowing equipment is relatively simple. The seeds are scattered on the surface before rotary tillage. When the rotary tillage is completed, the seeds are turned and buried in the ground with the soil. The horizontal distribution of the seeds is relatively uniform, but the vertical distribution is poor. Some of the seeds are either exposed on the surface or buried If it is too deep, it cannot germinate; if some seeds are covered with too shallow soil, although they can germinate, they are vulnerable to freezing damage or drought and cannot survive the winter; this will cause waste of seeds and loss of water and fertilizer at the seedling stage. This sowing method cannot guarantee the actual effective sowing amount and germination rate per mu.
