Pneumatic conveying no-till subsoiling fertilization seeder

Abstract

The invention provides a pneumatically conveyed no-tillage subsoiling and fertilizing seeder, which is characterized in that: along the traveling direction, the seedling belt cleaner is installed under the inner side of the front end of the frame side plate; The auger is located at the front end of the suppression wheel and is connected with the transmission of the suppression wheel. The ditching fertilizer applicator and the seed distributor are installed on the frame, between the seedling belt cleaner and the soil cover device; the material box is divided into a seed chamber and a In the fertilizer room, side panels are arranged on both sides of the partition in the seed room and the fertilizer room to form the seed ventilation channel and the fertilizer ventilation channel. The fertilizer discharger and the seed metering device are located at the bottom of the fertilizer ventilation channel and the seed ventilation channel; The input end of the fan is connected to the main gearbox through the speed increaser, the outlet of the fan is connected to the seed ventilation channel and the fertilizer ventilation channel, the two ends of the seed guide pipe are respectively connected to the seed ventilation channel and the seed settler, and the two ends of the fertilizer guide tube are respectively connected to the The fertilizer ventilation channel is communicated with the fertilizer settler. The invention has the advantages of accurate sowing and fertilization, anti-congestion and excellent working performance.

Description

technical field [0001] The invention relates to a pneumatic conveying type no-tillage subsoiling fertilization seeder, which belongs to the technical field of agricultural machinery. Background technique [0002] As the second largest grain crop in China, wheat is of great significance to ensuring national food security and improving the quality of life. At present, most of the wheat seeders used are mechanical or pneumatic seeding. For example, a wheat rotary tillage and fertilization seeder (201210198434.8) published in the Chinese invention patent can realize fertilization first, then rotary tillage, and then sowing and covering soil. However, the use of full-width stubble removal not only affects the effect of conservation tillage, but also destroys the soil ecological environment. In addition, the use of fertilization first and then rotary tillage seriously affects the performance of fertilizer efficiency; and its seed guide tube must be linear to ensure the seed It ca...

Problems solved by technology

Most of the currently used wheat seeders are mechanical seeding or pneumatic seeding. For example, a wheat rotary tillage and fertilization seeder (201210198434.8) published by the Chinese invention patent can realize fertilization first, then rotary tillage, and then sow and cover soil. However, the use of full-width stubble removal not only affects the effect of conservation tillage, but also destroys the soil ecological environment. In addition, the use of fertilization first and then rotary tillage seriously affects the performance of fertilizer efficiency; and the seed introduction tube must be straight to ensure that the seeds Otherwise, it will affect the sowing accuracy of the seeds; another example is the pneumatic no-tillage seeder (200810110084.9) published by the Chinese invention patent, which can realize stubble breaking, ditching, sowing, and soil covering in the field. , suppression, and paving combined operations. The seeding adopts a central seeding structure of a collection and row type, which realizes long-distance transportation of seeds. However, the machine has problems such as seed drill seeding, unstable spring tooth covering soil, and insufficient airflow sorting accuracy.
