Abstract

A crop straw cutting machine belongs to the technical field of agricultural machinery. A fixed cutter is disposed on the lower portion of a frame, a crankshaft is fixedly mounted on the frame through bearings, a flywheel is fixedly mounted at one end of the crankshaft, a swing arm is disposed right above the fixed cutter, two ends of the swing arm are hinged to one end of a long connecting rod and one end of a short connecting rod respectively, the upper end of the long connecting rod is hinged to an eccentric shaft crank portion of the crankshaft, the upper end of the short connecting rod is hinged to the frame through a pin, and a moving cutter is fixedly mounted right below the swing arm. The moving cutter has vertical composite motion for double acting, straws are easy to cut off, power of a motor can be lowered effectively, acting force upon the cutters is small, wear of cutting edges can be decreased, and cracking of the cutting edges can be prevented.

Description

A kind of agricultural crop straw clipper

Technical field

The present invention relates to a kind of agricultural crop straw clipper, belong to agricultural machinery technological field.

Background technology

At present; Original as fertilizer sources and the stalk of the crops of abandoning because science and technology development, are developed and the approach of other many comprehensive utilizations effectively; Such as: with feed, fertilizer, the fuel of agricultural crop straw exploitation, and other diversified purposes.Before agricultural crop straw development and use, generally must shear disconnected the processing to agricultural crop straw, still, existing stalk cutting machine generally is to be made up of frame and fixed cutting tool and moving cutting knife; Wherein moving cutting knife is fixed on above the slide block, and slide block is done single moving both vertically up and down under the driving of drive unit, so; The edge of a knife also is to make horizontal ground motion up and down up and down, because stalk generally all has certain toughness, causes shear effect bad; The power that machine consumed is bigger, simultaneously, because the power of the shearing that edge of a knife position is born is bigger; Simultaneously, because the shearing force that edge of a knife position is born is bigger, so; The edge of a knife of cutting knife is easy abrasion not only, simultaneously, also can occur the phenomenon of chipping easily.

Summary of the invention

The objective of the invention is to: a kind of stalk clipper is provided, overcomes the existing existing above-mentioned defective of stalk clipper.

The present invention realizes that the technical scheme that I adopted of above-mentioned purpose is: described stalk clipper comprises; Frame, fixed cutting tool, moving cutting knife, short connecting rod, bearing pin, swing arm, motor, small belt pulley, belt, flywheel, bent axle, long connecting rod, bearing are formed; At the frame lower position fixed cutting tool is installed, on frame, installs and fixes bent axle, install and fix flywheel in the end of bent axle through bearing; Top in frame is mounted with motor; Install and fix small belt pulley on the described motor shaft, link to each other through belt between flywheel and the small belt pulley, the position is provided with swing arm directly over fixed cutting tool; Described swing arm two ends are hinged with an end of long connecting rod and short connecting rod respectively; An other end of said long connecting rod and the eccentric shaft of bent axle turn the position and are hinged, and an other end of said short connecting rod is hinged through bearing pin and frame, under swing arm, installs and fixes moving cutting knife.

Operation principle of the present invention is: motor rotates through the belt drives flywheel, because flywheel and crankshaft installed be fixed together, so; Bent axle just rotates with flywheel, and under the drive of bent axle, long connecting rod just drives swing arm and does swing up and down; Because the left end of swing arm is hinged through short connecting rod and frame; So swing arm is done the compound motion that swings simultaneously when moving up and down.

Beneficial effect: can be found out by operation principle of the present invention: the moving cutting knife on swing arm is done shearing up and down to material on the one hand, simultaneously, does the tearing action of left and right directions again; So under the effect of moving cutting knife double reaction plus, material cuts off easily; Can reduce the power of motor effectively, simultaneously, the active force that acts on the cutting knife is less; Not only can reduce the wearing and tearing of cutting edge, can also prevent the generation of the chipping accident of the edge of a knife.

Description of drawings

Accompanying drawing 1 is a mechanism principle figure of the present invention;

Shown in Fig. 1: 1, frame; 2, fixed cutting tool; 3, moving cutting knife; 4, short connecting rod; 5, bearing pin; 6, swing arm; 7, motor; 8, small belt pulley; 9, belt; 10, flywheel; 11, bent axle; 12, long connecting rod; 13, bearing.

Embodiment

Frame 1 is used the method manufacturing of steel plate welding or casting; At frame 1 lower position fixed cutting tool 2 is installed, on frame 1, installs and fixes bent axle 11, install and fix flywheel 10 in 11 ends of bent axle through bearing 13; Be mounted with motor 7 on the top of frame 1; Install and fix small belt pulley 8 on 7 in the described motor, link to each other through belt 9 between flywheel 10 and the small belt pulley 8, the position is provided with swing arm 6 directly over fixed cutting tool 2; Described swing arm 6 two ends are hinged with the lower end part of long connecting rod 12 with short connecting rod 4 respectively; The eccentric shaft of the upper end of said long connecting rod 12 and bent axle 11 turns the position and is hinged, and the upper end of said short connecting rod 4 is hinged through bearing pin 5 and frame 1, under swing arm 6, installs and fixes moving cutting knife 3.
