Multifunctional rotary tillage, fertilization and seeding machine

Abstract

The invention relates to a multifunctional rotary tillage, fertilization and seeding machine, in particular to a multifunctional rotary tillage, fertilization and seeding machine suitable for seeding of rice, wheat and oilseed rape, which belongs to the technical field of agriculture and forestry machines. The multifunctional rotary tillage, fertilization and seeding machine comprises a rack; a rotary tillage ditching mechanism and an auxiliary ditching mechanism are arranged on the front part of the rack, a seeding and fertilization mechanism is arranged in the middle part of the rack, and a pressing and covering mechanism is arranged on the rear part of the rack; one side of the rack is provided with a first speed changer connected with an external power output end, and the other side of the rack is provided with land wheels; the seeding and fertilization mechanism comprises a fertilizer unit and a seeder unit, a power output end of the first speed changer is connected with a power input end of the rotary tillage ditching mechanism, and the land wheels are connected with power input ends of the fertilizer unit and the seeder unit through transmission chains, respectively. The multifunctional rotary tillage, fertilization and seeding machine has the functions of simultaneously performing rotary tillage, fertilization and seedling in one operation.

Description

technical field [0001] The invention relates to a fertilizing and seeding machine, in particular to a multi-functional rotary tillage and fertilizing and seeding machine suitable for sowing rice, wheat and rapeseed, belonging to the technical field of agricultural and forestry machinery. Background technique [0002] According to the applicant's understanding, most of the planters currently on the market have shortcomings: 1) Rotary tillage and fertilization operations must be performed before sowing operations, which increases the number of times the equipment goes to the ground, and multiple compactions on the ground are not conducive The growth of crops increases the production cost at the same time; 2) Usually it can only be adapted to sow one or a few crops with the same particle size, and cannot adapt to the sowing requirements of rice, wheat, and rape at the same time. Seeds with a large difference need to be realized by replacing different seed meters, which is troub...

[0002] According to the applicant's understanding, most of the planters currently on the market have shortcomings: 1) Rotary tillage and fertilization operations must be performed before sowing operations, which increases the number of times the equipment goes to the ground, and multiple compactions on the ground are not conducive The growth of crops increases the production cost at the same time; 2) Usually it can only be adapted to sowing one or a few crops with the same particle size, and cannot meet the sowing requirements of rice, wheat, and rapeseed at the same time. Seeds with a large difference need to be realized by replacing different seed meters, which is troublesome to operate; 3) The seeding rate is adjusted by changing the effective working length of the seed meter or replacing a different seed wheel, and the adjustment range is relatively large. small, low precision
