Corn strew grinding return-to-field machinery

Abstract

The corn stalk crushing and throwing machine includes one frame, one spiral throwing cutter with one shaft mounted through rolling bearing onto the frame, one horizontal pressing wheel mounted through sliding bearing onto the frame, one hood and guide plates in the back part of the hood. It features the increased groups of blades mounted homogeneously onto the cutter shaft and the guide plates mounted through an angle regulating mechanism. During operation, the high speed rotating blades produce axial force to through the crushed stalk homogeneously in certain angle range.

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 ...
