An integrated equipment for fertilization, film spreading and seeding compound operation

Abstract

The invention discloses an integrated equipment for fertilization, film spreading and seeding compound operation, which includes a tractor for paddy fields, and a fertilization unit connected to the frame of the tractor for paddy fields, a film spreading unit, a seeding unit, and a control unit; the tractor for paddy fields The fertilization unit, film spreading unit, and seeding unit are arranged sequentially from front to back in the direction of advancement, and the control unit is arranged on the frame of the paddy field tractor for coordinated control of the fertilizing unit, film spreading unit, and seeding unit; The seed metering unit includes a perforated seed metering mechanism that reciprocates up and down. After the film laying unit lays the mulch, the perforated seed metering mechanism makes holes on the mulch film and discharges seeds into the holes of the mulch film. The invention enables mechanized and automatic operation of the mulch perforating process in the mulching sowing technology, reduces labor intensity and improves planting work efficiency.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an integrated equipment for fertilization, film spreading and seeding compound operations. Background technique [0002] Rice is an important grain crop in my country, accounting for about 40% of the total grain output. Rice cultivation is an important part of rice cultivation. The rice cultivation methods in my country mainly include transplanting and direct seeding, of which rice transplanting accounts for about 60-70% of the rice planting area, but this method is labor-intensive and low in efficiency, which restricts the cultivation of rice The sustainable development of production, especially the rapid advancement of urbanization in my country, labor shortage, and rising labor costs, for this reason, rice direct seeding, especially precision direct seeding, has gradually become the development direction of rice planting in my country, and the mechanization syste...

Problems solved by technology

The above problems lead to an increase in the amount of rice seeds used, and an increase in production costs. At the same time, temperature, extreme weather, and insect pests cause rice production to decrease or even fail.

In order to solve the problems existing in rice direct seeding, some scholars have carried out the application of seed coating technology in rice direct seeding, and have achieved certain results, but there are still some problems: first, rice seeds are coated with a certain thickness of medicine, and when sowing and rubbing Second, the shape and size of the coated seeds are different, and accompanied by shedding drug impurities, which affect the normal operation of the seed metering device and cannot complete accurate sowing; third, the direct seeding of rice mostly uses germination-treated buds. It is easy to cause damage to the seeds after coating, and it is difficult to sow seeds immediately after coating. At the same time, my country has a vast territory and a large area of ​​rice planting. The technical requirements for seed coating are also different, which cannot meet different regions. technical needs

[0005] In the plastic film mulching sowing technology, there is a process that needs to punch the plastic film on the soil surface to provide openings for the seedlings to grow out of the plastic film, which is called seedling release. However, the implementation of the plastic film drilling in the existing plastic film covering sowing technology is mainly done manually , that is, after the soil surface of the paddy field is covered with plastic film, it is necessary to manually punch holes in the plastic film, which is labor-intensive and low-efficiency
