Combined air-suction type seeder and air-suction type seeding system

Abstract

The invention provides a combined air-suction type seeder and an air-suction type seeding system and relates to the field of agricultural machinery. The air-suction type seeding system comprises a tractor, a driving device and a the combined air-suction type seeder; the combined air-suction type seeder comprises a bearing cart, an air-suction type seeding device, a vacuum fan assembly, a fertilizing device and a loose tillage device; the bearing cart comprises a reduction gearbox, a bearing frame, a plurality of rubber wheels, a plurality of shock absorbers and at least one cross shaft; the air-suction type seeding device comprises a seed accommodating box, an air-suction type seed sowing device, a vacuum pipeline and a blanking pipeline, the air-suction type seed sowing device is connected with the vacuum fan assembly through the vacuum pipeline, and the air-suction type seed sowing device is connected with the seed accommodating box; the loose tillage device comprises a groundbreaking and furrowing shovel, a rotary tillage component and a countersunk head component; the fertilizing device comprises a fertilizer box and a fertilizing pipe. Compared with the prior art, the combined air-suction type seeder is good in loose tillage effect, high in seeding efficiency, low in leakage sowing rate and good in seeding effect.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a combined air-suction seeder and an air-suction seeding system. Background technique [0002] With the rapid advancement of industrialization and urbanization, the consumption demand of grain and other major agricultural products has grown rigidly, and the constraints on arable land and water resources have become increasingly severe. The task of planting development is very heavy. It is necessary to speed up the transformation of the development mode of the planting industry, strengthen the construction of facilities and equipment, optimize the planting structure, and rely on scientific and technological progress to improve resource utilization and land output. [0003] With the agricultural technology and the demand of people's living water, it is imminent to increase the output of agricultural products. For example: potato, corn, wheat and other crops, for a long time, ...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the seeders in the domestic market are parts with outer grooved wheels as the core work. Due to design reasons, there are uneven sowing phenomena, and even missed sowing, which causes a lot of work in the later stage of sowing, and even causes crops to fail. massive production cuts

Moreover, the work is not stable, there are many faults, the joint operation cannot be completed, and the efficiency of the whole machine operation is low
