Corn strew grinding return-to-field machinery

Abstract

The invention provides a corn stalk crushing and returning machine, which includes a throwing knife, a frame, and a pressing wheel horizontally installed on the frame, a machine cover, and a deflector, wherein the pressing wheel is installed on the rear lower part of the frame through a sliding bearing, The knife shaft is installed on the frame through rolling bearings, and the knife is evenly fixed on the knife shaft through the knife seat in a helical line. There are multiple deflectors on the rear of the hood, and the feature is that several sets of fan blades are added along the shaft. The blades are evenly distributed on the cutter shaft, and multiple fan blades in the same group are evenly distributed around the same circumference of the cutter shaft at a certain inclination angle; the deflector is welded on the head of the adjusting bolt, and is movably installed on the rear of the hood by the adjusting bolt. On the inner side, the angle between it and the forward direction is adjusted by the adjusting mechanism. When working, the high-speed rotating fan blades generate a certain axial force, so that the crushed straw can adjust the throwing direction through the movable deflector, so that it can be thrown in a fan shape, change the width of the throwing, and make the straw throwing more uniform. Excellent working performance.

Description

technical field [0001] The invention provides a corn stalk crushing and returning machine with fan blades, which belongs to the technical field of agricultural machinery. Background technique [0002] At present, the general-purpose straw crushing and returning machines are mostly composed of a frame, a machine cover, a pressing wheel, a rotating knife shaft, a fixed knife seat, a throwing knife, and a deflector. The pressing wheel is installed on the rear lower part of the machine cover through sliding bearings; the rotating knife shaft is installed on the machine cover through rolling bearings, and the fixed knife seat is evenly welded on the knife shaft in a spiral line; the moving knife and the fixed knife seat are generally connected by bolts. The two sides of the hood are welded together with the frame, and a plurality of deflectors are welded on the rear inner side of the hood, and the direction is perpendicular to the hood and is the same as the forward direction of ...

AI Technical Summary

Problems solved by technology

Since the width of the straw returning machine is smaller than the width between the two driving wheels of the tractor, when the straw returning machine is working normally, the crushed straw will be thrown unevenly in the field, which will affect the growth and development of wheat in the future.
