A large straw crushing and returning machine

Abstract

The invention provides a large-scale straw smashing field returning machine which comprises a machine frame, a gear box, a cover shell, a fixed blade, a movable blade, a right side board of the machine frame, a left side board of the machine frame, bearing seats, bearings, a right flail knife shaft, a power output shaft of the gear box and a left flail knife shaft. The left side board of the machine frame and the right side board of the machine frame are respectively provided with one bearing seat and each bearing is arranged in the corresponding bearing seat. The gear box is located in the middle of the machine frame and the power output shaft of the gear box is located at the bottom of the gear box. The right flail knife shaft is located at the right side of the gear box, the inner end of the right flail knife shaft is connected with the right end of the power output shaft of the gear box, and the outer end of the right flail knife shaft is installed in the bearing at the right side. The left flail knife shaft is located at the left side of the gear box, the inner end of the left flail knife shaft is connected with the left end of the power output shaft of the gear box, and the outer end of the left flail knife shaft is installed in the bearing at the left side. The large-scale straw smashing field returning machine has the advantages that the flail knife shafts of the straw smashing field returning machine are directly driven by the power output shaft of the gear box, so that a transmission system is simplified, the use reliability of the straw smashing field returning machine is improved, and the straw smashing effect is good.

Description

Technical field [0001] The invention belongs to a farmland working machine, in particular to a large-scale straw crushing machine. Background technique [0002] Crushing crop straws and returning them to the field is beneficial to increase the organic matter and nutrient content of the soil, improve the physical properties of the soil, increase the biological activity of the soil, and have a significant effect on increasing production.
