Abstract
The utility model relates to a small combine harvester for wheat matched with a small four-wheel tractor, mainly composed of a cutting component, a threshing component, a cleaning component, etc. A cutting device adopts an upper cutting knife and a lower cutting knife, and each cutting knife has the structure of double acting knives driven by a pair of cylindrical cams. The upper cutting knife just cuts ear heads and sends the ear heads to a transport gap bridge. The lower cutting knife cuts leaving straws and lays the leaving straws in field. A threshing device is the tapered drum with rasp bars of an axial flow type, which can simultaneously finish threshing and separating functions. A cleaning shoe adopts the structure of an axial flow fan and a circular wind channel. Due to the adoption of the structure, the feed quantity of the small combine harvester for wheat decreases 60%. The loads of threshing and cleaning devices are reduced, so power consumption is obviously reduced. Threshing rate, separating rate and other operation quality index are obviously increased. The small combine harvester for wheat has simple structure and low cost.
Description
The utility model belongs to agricultural machinery, particularly a kind of that can gather in the crops wheat and the supporting novel combined harvester of tractor with small four wheels.
Existing and the supporting wheat combine of tractor with small four wheels all are dwindling on the big-and-middle-sized combined harvester size, and operation principle does not change.So the outstanding problem that embodies in the work is exactly the underpower of tractor, thereby has caused operation quality low, yield loss rate height, the problem of functional reliability difference; And complex structure, weight are big, the manufacturing cost height.
The purpose of this utility model is that a kind of novel small-sized wheat combine will be provided, and it can solve the under powered problem of tractor effectively, and can improve operation quality, reduces yield loss, optimizes complete machine structure, reduces production costs.
The purpose of this utility model is achieved in that the front portion that all working parts of this reaping machine all is configured in tractor, and the required drive of reaping machine all working parts provides by the main transmission clutch sprocket wheel of installing on the engine belt pulley.Threshing and separator are the drum with rasp bars axial-flow type that tapering is arranged, and both are integrated; Tanker is configured in the bottom of cleaning unit; These three big parts all are fixed on mechanism on the results body with liter, and are fixed in by body and bracing piece on the guard and crossbeam of tractor front portion.Ceding of Taiwan frame hinge is coupled to the front upper place of body, by elevating mechanism make ceding of Taiwan frame front end cutter and blow that the standing grain fan rises or landing.Cutter adopts two-layer up and down, and adjustability is big, and the upper strata cutter is only cut off the fringe head and send into to carry and passes a bridge, the remaining stem stalk of lower floor's cutter cutting, and with its lay in the field; Two moving knife structures that two cutteves all adopt a pair of cylindrical cam to drive.Owing to adopt said structure, make the feed quantity of reaping machine reduce 60%, significantly reduced the load of threshing, separation and cleaning mechanism, thereby power consumption significantly reduces, make threshing performance, separation rate and all other operational indicators improve greatly, and this is simple in structure, running is steady, cost is low.
Fig. 1 is the principle assumption diagram according to the small-sized wheat combine that the utility model proposes.
Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.
Small-sized wheat combine is mainly by tractor with small four wheels (1), body (2), tanker (3), cleaning mechanism (4), elevating mechanism (5), profiling sled mechanism (6), nearside divider (7), following cutter (8), cutter transmission mechanism (9), upper cutter knife (10) blows standing grain fan board (11), blow standing grain fan (12), fan belt (13) is carried and is passed a bridge (14), ceding of Taiwan frame (15), ceding of Taiwan driving-chain (16), hinge wheel (17), minor sprocket (18), installed threshing separator (19), roller sprocket (20), tightener sprocket (21), main transmission chain (22), bracing piece (23), main transmission clutch sprocket wheel (24), clutch shifter handle (25) is formed.The required drive of this machine provides by the main transmission clutch sprocket wheel of installing on the engine belt pulley (24); The clutch of clutch sprocket wheel is partly adopted castellated, realizes the cut-out and the combination of power by clutch shifter handle (25).The all working parts of reaping machine are fixed on the guard and crossbeam of tractor (1) by body (2) and bracing piece (23); Cutting tool (15) hinge is coupled to the front upper place of body (2), by elevating mechanism (5) make cutting tool (15) front end cutter (8) (10) and blow standing grain fan (12) and rise or land; Elevating mechanism is by lifting sleeve and the gentle Suo Zucheng of pulley.
This reaping machine cutter adopts upper and lower two-layer configuration, i.e. upper cutter knife (10) and following cutter (8); Upper cutter knife (10) is only cut off the fringe head and send into to carry and passes a bridge (14), following cutter only cut remaining stem stalk and with its lay in the field; Two cutteves (10) (8) all adopt two moving knife reciprocating structures, drive cutter with a pair of cylindrical cam (being cutter transmission mechanism (9)) and do relatively reciprocating motion.To realize impulsive force and inertia force to the smooth cutting and the motion of minimizing moving knife of stem stalk.Dial the standing grain device and adopted the centrifugal standing grain fan (12) that blows to drive, play the effect of guiding, support stem stalk and lay, can adjust the height and the blowing angle of blowing standing grain fan board (11), make and dial standing grain effect the best according to the height of crop by fan belt (13).And reduced the seed loss.Threshing separates dress (19), and to adopt cylinder be the rasp bar axial-flow type that tapering is arranged, and threshing with separate both and be integrated, quilt is taken off thing one end-grain cutting to feeding, and the other end tangentially flows out, and finishes threshing simultaneously and separates two functions.Cleaning mechanism (4) adopts the structure in aerofoil fan and circular air channel; Light foreign material material is blown away, and reaches the purpose of grain clearly.Tanker (3) is configured in the bottom, cleaning unit, collects the clean grain of having taken off.
The power transmission route of this reaping machine is by main transmission clutch sprocket wheel (24), drives roller sprocket (20) and hinge wheel (17) by main transmission chain (22) and tightener sprocket (21); The belt pulley of the drum shaft other end drives clear grain fan; Hinge wheel (17) and minor sprocket (18) are on same axle, and minor sprocket (18) drives cutter transmission mechanism (9) by ceding of Taiwan driving-chain (16), carry simultaneously and have received the fringe head.The belt pulley of the other end of hinge wheel (17) axle drives by fan belt (13) and blows standing grain fan (12).
