Abstract

A corn harvester comprises a harvesting mechanism, a walking mechanism and a stalk crushing mechanism. The harvesting mechanism is mounted at the front of a four-wheel tractor of the walking mechanism, a reel, a snapping device and a discharge device of the harvesting mechanism are driven to work by transmitting power forwards via belt pulleys of a diesel engine, through a baffle plate and a line separating device, corn stalks are shifted between a positive spiral snapping roller and a negative spiral snapping roller to be snapped by the reel, the snapped corn stalks are downwardly discharged, and corn ears enter an ear collecting hopper to be discharged towards a lateral surface by spiral blades. The stalk crushing mechanism is mounted at the rear of the four-wheel tractor, power is transmitted backwardly by a clutch of the tractor to drive a cutting machine and a crushing machine to rotate, the cutting machine cuts the snapped corn stalks from roots and sends the corn stalks to the crushing machine to be crushed, and then the crushed corn stalks are enabled to return to fields. The corn harvester is used for mechanically harvesting corns.

Embodiment

Complete machine structure is consulted Fig. 1, Fig. 2: harvesting mechanism is installed in the place ahead at the running gear four-wheel tractor, be fed forward power by the belt pulley on the diesel engine (1) to harvesting mechanism, about two sliding bars (3) about reaping machine framework (2) rear side are inserted in the notch (5) of two columns (4), column (4) is fastened on the crossbeam (6) in four-wheel tractor the place ahead, makes after belt (25) tensioner and pin with the card silk.By the belt pulley (1) of diesel engine by the belt pulley (8) of jaw clutch (7) is housed on belt (25) the lead agency frame (2), when starting, separate by control stick control power, connect by control stick control power during operation, by the gear transmission device in the gear chamber (9), respectively organize right-handed screw stripping roller (10) about drive, with backpitch stripping roller (11) in the opposite direction to changeing, head end at two right-handed screw stripping rollers (10), installing worm and wormwheel (12), driving meshing thumb wheel (13) rotates, between backpitch stripping roller (11) and right-handed screw stripping roller (10), be provided with collection fringe bucket (14), the helical blade (15) that rotation is arranged in the collection fringe bucket (14), in collection fringe bucket (14) the place ahead branch's device (16) is arranged, there is baffle plate (17) on both sides.Under the effect of baffle plate (17) and branch's device (16), the corncob bar is uprightly dragged on to plucking fringe between the right-handed screw stripping roller (10) that changes and the backpitch stripping roller (11) by the thumb wheel (13) that rotates, stalk is discharged downwards, the corncob of removing falls in the collection fringe bucket (14), is discharged to the side by the helical blade (15) that rotates in the collection fringe bucket (14).

Crushed stalk mechanism is installed at running gear four-wheel tractor rear; by the clutch (18) of four-wheel tractor transmitting power backward; drive the friction clutch (19) of crushed stalk mechanism; connect power during operation, disconnect power, the coaxial belt pulley (20) that jaw clutch (7) are housed that is transferred to during turning; during road traveling; separate by control stick control power, protection friction clutch (19), operation connects power by control stick in the field.The belt pulley (22) that drives grinder main shaft (21) rotates, drive by same shaft pulley (23) again and be installed in grinder the place ahead rice cutter main shaft (24) rotation, go up the rice crop-cutter (26) that a plurality of Y types front and back bifurcated is installed at rice cutter main shaft (24), can slice off stalk from root during rotation, flow to grinder backward.Go up string at grinder main shaft (21) and adorn a plurality of disks (27), and go up installation a plurality of flail knives (28) at disk (27), flail knife during rotation (28) inserts in the space that is ranked between the cutter (29) of rear side, effectively crushing straw.

Because rice cutter all rotates backward with identical direction with grinder, the maize straw that rice cutter stays harvesting mechanism slices off from root sends into grinder, under the effect of flail knife (28) and stationary knife (29), cornstalk is pulverized and is shed on the ground.Utilizing the hydraulic arm (30) of running gear four-wheel tractor to hang pulverizing chamber frame (31) is the axle center with the main shaft (32) of friction clutch (19), and arc is to lifting, the height on land wheel (33) length of support ground.Finished the job task of corn picker and straw chopping and returning.
