Field returning machine capable of embedding materials into soil

Abstract

The invention discloses a field returning machine capable of embedding materials into soil. The returning machine comprises a vehicle underframe and a driving wheel, wherein a crushing box is installed at the upper end of the vehicle underframe, a splash-proof opening is formed in the top of the crushing box, four groups of crushing rollers are arranged below the splash-proof opening, roller shafts are arranged at the two ends of each crushing roller, the roller shaft at one end of each group of crushing rollers is sleeved with a chain wheel, two adjacent groups of chain wheels are connected through a chain, gears are mounted on the roller shafts at one ends of the two groups of crushing rollers in the middle and are meshed with each other, and ring roller blade groups are arranged on the roller surfaces of the crushing rollers at equal intervals. According to the field returning machine capable of embedding the materials into the soil, airflow is sprayed out through a spraying pipe in a material mixing cavity, straw powder is splashed and mixed with water flowing out of a spraying nozzle, on one hand, the discharging speed of the straw powder can be increased conveniently, discharging from a square pipe is facilitated, on the other hand, the powder is dissolved in water, the purpose of dust removal is achieved, environmental pollution is reduced, and a better use prospect is brought.

Description

technical field [0001] The invention relates to the field of agricultural machinery design, in particular to a field-returning machine for embedding materials into the soil. Background technique [0002] Straw returning to the field is a measure to increase soil fertility that is generally valued in the world today. It can increase fertilizer and increase production while eliminating the air pollution caused by straw burning. Straw returning to the field can increase soil organic matter and improve soil structure. Make the soil loose, increase the porosity, reduce the capacity, and promote the activity of microorganisms and the development of crop roots; after the existing straw returning machine crushes the straw, it generally directly sprinkles the straw debris and covers it on the surface of the farmland, which will prolong the life of the straw. The rotting time reduces the efficiency of straw use, and causes the seeds to be easily wrapped by the straw so that they canno...

[0002] Straw returning to the field is a measure to increase soil fertility that is generally valued in the world today. It can increase fertilizer and increase production while eliminating the air pollution caused by straw burning. Straw returning to the field can increase soil organic matter and improve soil structure. Make the soil loose, increase the porosity, reduce the capacity, and promote the activity of microorganisms and the development of crop roots; after the existing straw returning machine crushes the straw, it generally directly sprinkles the straw debris and covers it on the surface of the farmland, which will prolong the life of the straw. The rotting time reduces the efficiency of straw use, and causes the seeds to be easily wrapped by the straw so that they cannot touch the soil when the farmland is cultivated, which reduces the germination rate of the seeds. The harshness of the working environment has brought certain adverse effects in the process of use. Therefore, we propose a field returning machine for inserting materials into the soil.
