multifunctional seeder

Abstract

The invention belongs to the field of agricultural machines, and particularly relates to a multifunctional seeding machine for planting paddy and wheat in a large area. The multifunctional seeding machine comprises a machine frame, a first beam, a second beam, plowing shovels, plowing shovel frames, a flattening device, a seeder assembly, a broken shaft connection regulator and U-shaped clamps. The distance between the plowing shovel frames is adjusted by adjusting the distance between the U-shaped clamps arranged on the first beam and the second beam, and the distance between the plowing shovels is further adjusted so that the aim of adjusting the seeding line spacing can be achieved. Each plowing shovel further comprises a plowing shovel accessory, each plowing shovel accessory can rapidly shoveled into hard soil and conduct deep plowing, and therefore the operating quality and the operating efficiency are ensured. Compared with the prior art, the multifunctional seeding machine has the advantages that the plowing procedure, the seeding procedure, the fertilizing procedure, the soil preparation procedure and other procedures can be completed at a time, and the multifunctional seeding machine is good in operating quality, high in efficiency and convenient to use, integrates multiple purposes, and is stable in performance and novel in structure.

Description

technical field [0001] The invention belongs to the category of agricultural machinery, in particular to a multifunctional seeder for planting rice and wheat in a large area. Background technique [0002] Rice and wheat are the main food crops in Ningxia, with a planting area of ​​more than 5 million mu. With the development of science and technology, the production of planting machinery and grains has greatly increased; Low energy consumption, high energy consumption, so as not to meet the needs of the current agricultural mechanized production. [0003] Existing implements have a single function. When engaged in farmland operations, one model is used at a time. As far as rice planting is concerned, after land preparation with the Hirata Instrument, proceed to: Rotary tiller or heavy harrow operation; grinding work; fertilization operations; secondary grinding; repressive operations; Sowing jobs. For these six different operations, different machines need to...

AI Technical Summary

Problems solved by technology

This single operation method has the following unfavorable factors. First, the operation cycle is long, the mechanical efficiency is low, and a lot of machinery and manpower need to be invested; second, the degree of compaction of the soil is large, resulting in uneven distribution of soil firmness, which affects crops. Third, if encountering rainy weather, the relevant autumn sowing operation procedures will be difficult to carry out, which will delay the autumn sowing time, which is not conducive to disaster resistance; fourth, the single operation cost is high, energy consumption is large, the time is long, and the wear and tear on the tractor is large, reducing the unit utilization
