Processing combined machine for grain harvesting and straw and stubble fertilizing and field-returning

Abstract

The invention provides a processing combined machine for grain harvesting and straw and stubble fertilizing and field-returning. The processing combined machine is composed of a header, a conveyor trough, a threshing main roller, a separating guide auxiliary roller, a ditching drive, a straw guide groove, a traveling system, a straw fertilizing biological fungus powder box, a spray amount control valve, a motor, a fungus powder pipe, a fan, an auxiliary air pipe, and a powder spraying opening. An inlet of the threshing main roller is connected with the conveyor trough, and an outlet of the threshing main roller is connected with an inlet of the separating guide auxiliary roller. The separating guide auxiliary roller is located on the back portion of the threshing main roller and is half of the threshing main roller in length. The separating guide auxiliary roller can improve the separating effect, and can guide threshed straws to the middle straw collecting ditch in the tail portion from the side of the machine so as to be favorable to returning the straws to field and bring convenience to subsequent no-tillage direct seeding. A straw and stubble fertilizing processing device can evenly spread biology fungus powder into field-returned straws and stubbles staying in field. The processing combined machine can utilize the biology fungus powder to quicken decomposition of straws and improve the organic fertilizer converting rate of straws, and has the advantages of being multipurpose, practical, and efficient, saving cost, increasing effects and the like.

Description

technical field [0001] The invention relates to a combined operation machine for rice and wheat harvesting, straw and root stubble fertilization and returning to the field, especially a simple and efficient combined operation machine for harvesting rice and wheat crops and straw and root stubble returning to the field with fertilizer. field of agricultural machinery. Background technique [0002] Traditional straw burial or rotary burial returning to the field can easily increase the soil pores, cause ventilation and accelerate moisture loss, thereby affecting seedling emergence; at the same time, it is difficult for the straw returned to the field to decompose in a short period of time and be used by crops. In the emission of CO 2 、CH 4 , N 2 O, H 2 At the same time as poisonous and harmful gases such as S, it will also compete with crops for nitrogen due to the consumption of nitrogen, which will cause yellow seedlings and even affect crop growth. [0003] The existin...
