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
The present invention relates to agriculture rotary tillage or seeding machinery technical field.
Background technology
Existing wheat seeder is the trench digging drilling, and sowing is with narrow, and it is concentrated to emerge, and fight for nutrient between the Miao Yumiao, and soil nutrient between two Gansu Province and moisture can not be fully utilized.And before the existing sower operation, need earlier with rotary tillage, soil preparation machine plough put in order after, sow again, tractor needs enter ground twice, can fulfil assignment, the energy consumption height, cost is big, operating efficiency is low.Common wheat sowing machine tool is simpler and easy, and seed is spread on the face of land before rotary tillage, and seed stirs with soil and is embedded in undergroundly when treating rotary tillage, and the seed horizontal distribution is more even, but vertical distribution is relatively poor, part seed or expose the face of land or bury dark and can not germinate; Though part seed earthing is crossed shallow can emerging, it is dead and can not survive the winter to be subject to freeze injury or arid; Cause seed waste and liquid manure loss in seedling stage, this seeding method can not guarantee every mu of effective seeding quantity of reality and germination rate.
Summary of the invention
The purpose of this invention is to provide a kind of rotary tillage broadcast sowing combined drill for wheat, structure uniqueness, reasonable, rotary tillage, broadcast sowing operation and can once finish, saving of work and time, save the energy, raise the efficiency, reduce cost, soil nutrient, moisture and utilization rate of fertilizer height can be realized uniform broadcasting basically, especially can make the seed level unanimity, can guarantee the requirement of the seed germination degree of depth more effectively,, save seed for seed provides the environment that germinates preferably, improve seed germination rate greatly, improved the growth quality and the gross yield of wheat.
Main technical schemes of the present invention is: a kind of rotary tillage broadcast sowing combined drill for wheat, comprise frame and hanger bracket, gear-box, rotary tillage mechanism, dispenser and grain tube thereof, it is characterized in that grain tube has more than 2 or 2, arrange the lateral separation, seed laterally all spreads device under the soil layer all being connected with below the grain tube, seed laterally all spreads the degree of depth that kind of mouth is positioned at the following requirement of soil layer that of device lower end under the soil layer, and seed laterally all spreads the back that device is located at rotary ploughing cutter shaft under the soil layer.
Seed laterally all spreads the preferred construction of device and is under the described soil layer: have the boxlike seed outer cover that laterally all looses, the horizontal upper end of all loosing outer cover of boxlike seed is provided with kind of a pipe, the fall lower end of kind of pipe is provided with the seed side and divides bar, the laterally all diffusing outer cover lower end of boxlike seed is positioned under the soil layer, the germination environment of boxlike kind, save seed, improved seed germination rate greatly, improved the growth quality and the gross yield of wheat; Easy to use, flexible, operating cost is low, and effect is remarkable, is a breakthrough to prior art; Tractor can also be finished fertilising, rotary tillage with once advancing, broadcast sowing, rises the whole operations in the ridge; Pressure roller has been added in the rear end of sower, face of land earthing after planting can be compressed, thereby for seed provides the environment that germinates preferably, improves germination rate; The ridge of rising of sower both sides is ploughed and both sides soil can be piled into the ridge, can reduce the artificial ridge operation that rises, and reduces labour intensity.
Be described in further detail below in conjunction with embodiment and accompanying drawing, but not as a limitation of the invention.
