A kind of precision seeder for wheat with wide seedling belt and its working method with less tillage and fertilizer application

Abstract

The invention relates to a wide-seedling-strip wheat precision planter achieving both minimal tillage and fertilizer and a work method thereof. The wide-seedling-strip wheat precision planter comprises a rack, a traction beam, seed discharging devices, rotary cultivators, openers, fertilizer applying mechanisms, pressing mechanisms, earthing mechanisms, compacting mechanisms, soil flattening mechanisms, ground wheels, seed boxes and seed discs. The seed discharging devices are mounted at the position, behind the traction beam, of the rack. The traction beam is fixedly mounted at the front end of the rack. The earthing mechanisms are mounted below the position, behind pressing wheels, of a connecting frame. Soil flattening wheels are mounted at the rearmost end of the rack. The ground wheels are mounted on the two sides of a rack of the seed discharging devices and connected with a driving shaft. An air suction device is adopted for seed taking and falling, the seed hole conveying belt seed discharging devices are used for wide-seedling-strip precision seed discharging, the whole seed taking and arranging process is controllable, meanwhile, a series of functions of seedling strip rotary tillage, ditching, fertilizer applying, pressing, earthing, compacting, soil flattening and the like are achieved, the workload of sowing wheat is reduced, and the precision and work efficiency of wheat sowing are improved.

Description

technical field [0001] The invention relates to the technical field of sowing agricultural machinery, in particular to a precision sowing machine for wheat with a wide seedling band that uses less tillage and fertilizer. [0002] technical background [0003] Wheat is an important economic crop in my country and the main source of food in northern China. The increase in wheat production and income is related to the development of the national economy. The quality of wheat sowing directly affects the quality of wheat growth conditions and the physiological processes such as wheat seed germination, emergence, tillering, and heading that determine yield formation. The existing wheat mechanized sowing technology has problems such as uneven distribution of plant spacing, inconsistent sowing depth, poor population quality, and low yield. "Wide seedling belt precision sowing" technology is one of the modern agricultural production technologies of "saving cost and increasing efficie...

Problems solved by technology

[0005] Aiming at the defects of the prior art, the present invention solves the problems of lack of wheat precision seeding machinery and low quality of existing seeds. The present invention provides a wide seedling-band wheat precision seeder and its working method with less tillage and fertilizer application. The planter adopts the air-suction needle seed picker to take and drop seeds, and the seed metering device with the seed hole conveyor belt to carry out precise seeding with a wide seedling belt. A series of functions such as front rotary tillage, ditching, fertilization, seed collection, seed arrangement, suppression, covering, compaction, and leveling
