Straw crushing body and crushing returning apparatus with same

Abstract

The invention discloses a straw crushing body and a crushing returning apparatus with the same and belongs to the field of agricultural machinery. The straw crushing body comprises a housing, a pickuproller, a main crushing roller, an auxiliary crushing roller, a first straw transfer roller, a second straw transfer roller, and a dual-roller crushing component; the main crushing roller is positioned above the right of the pickup roller; the auxiliary crushing roller is positioned above the left of the main crushing roller; the first straw transfer roller is positioned among the pickup roller,the main crushing roller and the auxiliary crushing roller; the second straw transfer roller is positioned on the left of the auxiliary crushing roller above the main crushing roller; a housing outletis arranged below the right of the main crushing roller. The straw crushing body has the advantages that the auxiliary crushing roller is designed at the upper right corner of the main crushing roller, part of straw is transferred to the auxiliary crushing roller through the two straw transfer rollers to take deep crushing, crushing time of straw from a housing inlet to the housing outlet can beextended, the straw can be fully crushed accordingly, and the straw may be finer and more uniform at the housing outlet.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a straw crushing main body and a crushing and returning device using the straw crushing main body. Background technique [0002] Straw returning has many advantages such as improving soil structure, increasing soil organic matter, improving soil fertility, and eliminating air pollution caused by straw burning. It has gradually become popular and produced good economic, ecological and social benefits. [0003] At present, the main method of returning corn stalks to the field in dry farming areas in northern my country is: corn harvesting machinery crushes the stalks and throws them on the surface while harvesting corn ears, and then plows them into the soil with rotary tillage machinery in the later stage, in order to achieve the goal of rotting and decomposing the stalks. Purpose. This is currently the simplest method of returning straw to the field, and it is also the model...
