Description

Micro combined reaping machine

The utility model relates to agricultural harvesting machinery, particularly is used to gather in the crops the micro combined reaping machine of paddy and wheat.

Existing combined harvester volume is big, Heavy Weight, complex structure, and all is the driving formula, is not suitable for the results of mountain area, hills and fritter field, soil.Present all types particularly, crop from after the cutter cuts to the threshing cylinder, conveying mechanism is very long, not only volume is doted on greatly, and makes grain, wheat loss increase the utilization percent reduction.In order to alleviate the work degree of mountain area, hills and fritter field, soil results paddy and wheat, the grain header or the thresher of special purpose have occurred, but can not once finish the work of harvesting and threshing.

The purpose of this utility model is the deficiency that exists at existing combined harvester, provides a kind of compact conformation, volume is little, in light weight, utilization percent is high, is applicable to that mountain area, hills and fritter field, soil once finishes the micro combined reaping machine of harvesting and threshing.

The purpose of this utility model is achieved through the following technical solutions: micro combined reaping machine, comprise frame, be installed in engine, moderate fluctuation wheel, decelerator, the handrail at frame rear portion, be installed in threshing cylinder, sieve plate, auger conveyor and the Yang Guqi of central rack, be installed in the cutter of frame front, group standing grain mechanism of both sides, be installed in the road wheel of bottom, be installed in the floating roller between two road wheels; The standing grain mechanism of dialling of each side is referred to form by three sprocket wheels, chain cover, chains and the standing grain of dialling that is installed on the chain, and is connected with branch standing grain sheet on the chain cover, and the front end of branch standing grain sheet is hinged with the branch straw; Engine drives main shaft by belt pulley and rotates, and two clutches that the control walking arranged on the main shaft and gather in the crops link with two sprocket wheels respectively, closed results clutch, and the sprocket wheel on the main shaft is by being rotated by movable sprocket drive threshing cylinder of linking to each other.Be fixed with two sprocket wheels on the cylinder shaft, wherein the winnow blade of sprocket wheel drive auger conveyor and auger conveyor axle head rotates together; The hinge wheel that another sprocket wheel on the cylinder shaft drives on the front axle rotates, be fixed with three conical gears and a spur gear on the front axle, two conical gears in opposite directions of inner face respectively drive one and dial the standing grain mechanism kinematic, being installed in the standing grain of dialling on the standing grain mechanism chain of dialling refers under the drive of drive sprocket, move upward obliquely, realize holding up the standing grain function; Conical gear that the conical gear drive of preceding shaft end is engaged with and coaxial eccentric wheel rotate, and eccentric wheel drives cutter by a connecting rod and makes reciprocal cutting movement; The spur gear of the front axle other end drives conveying cylinder by the spur gear that is engaged with and rotates, and makes conveyer belt realize conveying function.Closed Traction clutch makes another sprocket wheel on the main shaft drive the decelerator rotation, and reducer output shaft drives road wheels by two sprocket wheels and rotates forward, and floating roller also rotates thereupon.The moderate fluctuation at frame rear portion wheel can regulate and frame between the distance of vertical direction, making complete machine is that fulcrum carries out pitching with two road wheels, reaches control frame front end and holds up the on the spot effect of height of standing grain mechanism.It is characterized in that a floating roller is installed between two road wheels, the center of gravity of miniature reaping machine drops on this floating roller, so this function walks on very narrow loaning, also can rely on floating roller single wheel walking on the raised path through fields, is adapted at hills and mountain area operation.

Described micro combined reaping machine, it is characterized in that between cutter and the threshing cylinder outer cover by a section being that the groove of ∪ type is connected, ∪ type groove is over against threshing cylinder cover inlet, and ∪ type trench bottom top is equipped with a conveyer belt, and the length of ∪ shape groove and conveyer belt is all 50CM ± 5CM.Fringe head under the cutting is directly poured in the ∪ shape groove between cutter and threshing cylinder cover, auxiliary fringe head down at conveyer belt is drawn in threshing in the threshing cylinder cover by threshing cylinder, thereby make compact integral structure, volume-diminished, weight saving, and eliminated fully because the loss of being scattered that middle conveying is caused.Threshing cylinder with the threshing of fringe head after outside the residue foreign material discharge machine.Paddy of taking off or wheat be through sieve plate, and auger conveyor at last by outside the winnow blade output machine, thereby is realized combining to paddy or wheat.

The utility model compare with existing combined harvester have compact conformation, volume is little, in light weight, advantage that utilization percent is high, complete machine weight has only more than 100 kilogram, the I of wheelspan is to 40CM, can rotate 360 ° on the spot, flexible and convenient operation, be particularly suitable for mountain area, hills and fritter field, soil harvest operation.The utility model production cost is low, and price is low, promotes easily.
