Articulated combined soil preparation and sowing machine for leafy vegetables

Abstract

The invention relates to an articulated combined soil preparation and sowing machine for leafy vegetables and belongs to the technical field of agricultural machines. The articulated combined soil preparation and sowing machine comprises a front rack and a rear rack; the rear end of the front rack and a middle rack form a lockable sliding pair; the front end of the rear rack is hinged with the middle rack; the front rack is provided with an articulated gearbox and supports against a rotary tillage mechanism driven by and connected with the articulated gearbox; the rear of the rotary tillage mechanism is provided with a scraping plate; the middle rack supports against a front compression roller; the front end of the rear rack is provided with a sowing boot, and the middle of the rear rack supports against a sowing device; and the sowing device is driven by and connected with a rear compression roller supported at the rear end of the rear rack. By using the articulated combined soil preparation and sowing machine, all operation steps including soil cultivation and preparation, bedding, furrowing and sowing as well as earthing for bed compression formation can be completed at one step, and the mechanical production capacity of fast-growing leafy vegetables such as Chinese little greens can be comprehensively improved; and the articulated combined soil preparation and sowing machine has good applicability and universality and can meet the requirement open field and facility plantation on flat and sloping lands.

Description

technical field [0001] The invention relates to a soil preparation and sowing machine, in particular to a combined leaf vegetable and soil preparation seeder, which belongs to the technical field of agricultural machinery. Background technique [0002] Featherweed is a typical close-planted fast-growing leafy vegetable with small seeds, large sowing volume and short sowing cycle. Although the level of plowing and sowing technology has been greatly improved in recent years, most of them have poor soil fragmentation and easy blockage of seed tubes under the condition of heavy clay soil, and the operation performance is unreliable; and the existing plowing and seeding machines are mostly It is suitable for flat fields, and it is difficult to popularize and apply in steep slopes and hilly areas. [0003] According to the applicant's knowledge, there is currently a lack of leafy and vegetable joint operation equipment that integrates multiple functions of soil preparation, furro...

Problems solved by technology

Although the level of plowing and sowing technology has been greatly improved in recent years, most of them have poor soil fragmentation and easy blockage of seed tubes under the condition of heavy clay soil, and the operation performance is unreliable; and the existing plowing and seeding machines are mostly It is suitable for flat fields, and it is difficult to popularize and apply in steep slopes and hilly areas

[0003] According to the applicant's knowledge, there is currently a lack of leafy and vegetable joint operation equipment that integrates multiple functions of soil preparation, furrowing, sowing, and compaction. Planting chicken feathers still needs to use a small hand-held rotary tiller to prepare the soil first, and then manually divide the furrows. The furrows are ready, the furrows are leveled, and finally the seeds are sown manually or with a walk-behind seeder

This three-step method is not only labor-intensive and time-consuming, but also has low efficiency, and the uniformity of the seeds sown is poor, the sowing amount is large, and the reseeding rate of the walk-behind planter is high, which seriously wastes seeds.

In addition, this extensive planting method directly affects the efficiency and performance of the harvester
