Agricultural rotary tillage sowing machine

Abstract

The invention discloses an agricultural rotary tillage sowing machine. The agricultural rotary tillage sowing machine comprises seed falling devices, a rotary tillage knife roll, a fertilizer broadcasting hopper, a straw smashing disc, a fertilizer storage barrel, a seed box and a sowing rack. A header is arranged at the front end of the sowing rack, the header is provided with an upper hood, the straw smashing disc is installed at the tail of the hood, the fertilizer broadcasting hopper is arranged behind the straw smashing disc, the upper portion of the fertilizer broadcasting hopper is communicated with the fertilizer storage barrel, the rotary tillage knife roll is installed behind the fertilizer broadcasting hopper, multiple ditch pressing wheels are installed at the rear end of the rotary tillage knife roll, one seed falling device is arranged behind each ditch pressing wheel, and the upper portions of the seed falling devices are communicated with the seed box. The agricultural rotary tillage sowing machine is compact in structure and convenient to use, crop straw is effectively smashed, fertilizer is convenient to broadcast, the rotary tillage effect is good, sowing and seed earthing burying are convenient, the bottom flattening effect is good, one machine achieves multiple purposes, the sowing quality and efficiency are improved, and the cost of agricultural rotary tillage sowing is reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to an agricultural rotary tillage and seeding machine. Background technique [0002] At present, farmland sowing can be divided into manual sowing and mechanical sowing. Traditional manual sowing involves field operations such as ditching, sowing, fertilization, herbicide application, soil covering, and suppression. The advantages are simple operation and low requirements for production tools. The disadvantages are: It requires a lot of labor and a large amount of seeds, and it is difficult to control the row spacing and plant spacing. There are often problems of excessive dense planting or uneven density, uneven seedling emergence, and labor-intensive and time-consuming. Although mechanical seeding has improved the seeding rate and seeding uniformity, it is also affected by factors such as soil conditions, and there are also problems such as large seed ...

Problems solved by technology

[0002] At present, farmland sowing can be divided into manual sowing and mechanical sowing. Traditional manual sowing involves field operations such as ditching, sowing, fertilization, herbicide application, soil covering, and suppression. The advantages are simple operation and low requirements for production tools. The disadvantages are: It requires a lot of labor, a large amount of seeds are used, it is difficult to control the distance between rows and plants, and there are often problems of excessive dense planting or uneven density, uneven seedling emergence, and labor-intensive and time-consuming

Although mechanical seeding has improved the seeding rate and uniformity of seeding, it is also affected by factors such as soil conditions, and there are also problems such as large seed volume and unequal spacing, and there are also problems such as fertilization with the seeds and uneven application of pesticides.

[0003] The use of mechanical sowing has high efficiency and high cost. It needs to complete multiple processes such as surface crop straw removal, fertilization, rotary tillage, ditching, sowing, soil covering, and suppression leveling. It requires a variety of mechanical operations, which reduces the overall cost of agricultural sowing. efficiency, unable to meet the needs of agricultural production
