Description

Miniature grain combine

The utility model relates to a kind of grain combine, especially can hang supporting grain combine with small hand tractor.

At present, known grain combine mostly be self-propelled and with the backpack of four-wheel tractor; And to hang supporting type few with hand tractor, and its feeding mode mostly is half feeding pattern, and does not have cleaning plant, is mainly used in rice harves, the harvesting wheat in the incompatible north.

The purpose of this utility model provides and a kind ofly can hang the full feed type wheat and rice combine harvester be connected on the 5.8-8.8KW hand tractor, can finish simultaneously wheat or paddy rice harvesting, threshing, clean, collect operation such as grain.Load onto the harvest operation that can also carry out soybean behind the annex.

The purpose of this utility model is achieved in that the diesel engine on the hand tractor moved and is contained in special the having in gearbox back and turns on the power rack of tail wheel; In the gearbox front with a hitch with cutting, threshing, clean and grain conveyor is installed on the tractor, form combine.Its architectural feature is: the ceding of Taiwan directly links to each other with sheller unit, crank rocker sliding sash mechanism is adopted in the cutter transmission, ceding of Taiwan outlet is the threshing cylinder feeding mouth, one feeding roller is arranged between ceding of Taiwan outlet and threshing concave plate inlet, 6 piece flexible take off of the cereal of cutting off on ceding of Taiwan transport tube refer to take off send, by feeding roller feeding threshing cylinder.The notch board of sheller unit is a grid type, and threshing cylinder is an axial-flow type tapered rod dental roller, and feeding mouth is in the lower right, and stalk outlet is at left anterior-superior part, and straw discharges direction and grain header is 40 degree angles, discharges to the left front, is laid on the field piece that has gathered in.The blower fan of once cleaning is an air suction type, is located at left back, machine top, the blower fan chaff discharging port to the left back to discharging clever shell, foreign material such as broken straw rod.Grain conveyor is made up of a horizontal horizontal screw conveyor and a tilting lifting screw feeder that makes progress; The collection tanker is located at the rear of tractor revolver, is fixed on the power rack, and be equipped with secondary and clean screen box at its place suitable for reading, and tanker is filled the back by manually opening the unloading flashboard, and grain flows out outside the machine automatically.

Owing to adopt such scheme, can make the power power of small-power hand tractor be able to reasonable distribution, make the miniature wheat and rice combine harvester of this suspension type can carry out the grain harvest operation.

Below in conjunction with accompanying drawing the utility model is further specified.

In Fig. 1, header auger (3) is contained on the same frame with threshing cylinder (12), and feeding roller (4) is housed between them, and the attraction blower fan (9) that is used to clean is located at the left rear corner above the frame; Drive sprocket on clutch sprocket on the final drive shaft (8) and the tractor clutch wheel is connected with roller chain, 5 transmission pulley concial disks are housed, respectively transmission threshing cylinder (12), feeding roller (4), horizontal horizontal screw conveyor (5), attraction blower fan (9) and tilting lifting screw feeder (10) on it.Hanger bracket (7) is contained on the position of former installation power rack on the hand tractor gearbox, with 4 connecting rods (6) the combine body is hung to couple together.Miniature grain combine is when farm work, nearside divider (15) will cut the inside and outside crop in district separately, straw shift wheel (14) is dialled the crop that enters between the nearside divider of the left and right sides to cutter (1), cutter cuts off the crop cane, the crop of cutting off is in deadweight, swing to the ceding of Taiwan under tractor pace and the straw shift wheel mating reaction, deliver to the porch of ceding of Taiwan right side feeding mouth by header auger (3); Take off fingers (2) and feed under the mating reaction of roller (4) flexible, crop is grabbed into sheller unit by the bar tooth on the threshing cylinder (12) and carries out threshing, separates and clean.Crop makes garden Zhou Yundong and moves axially under threshing cylinder bar tooth, notch board (13) and cylinder top cover (11) guide plate mating reaction, shift to left end from the threshing cylinder right-hand member.Crop in moving process, be subjected to the bar tooth repeatedly strike, curry and on notch board (13), rub and threshing repeatedly.Grain falls by the grid hole of notch board (13), after attracting blower fan (9) air flow cleaning, fall in the horizontal horizontal screw conveyor (5), be sent to the lifting screw feeder (10) of left end, by promoting screw feeder (10) grain is delivered to grain dischzrging tube inflow collection tanker, the secondary on top is cleaned in the screen box, and cane is screened to be gone out outside the machine, and grain falls into the collection tanker.The assorted surplus blower fan (9) that is attracted sucks outside the blower fan discharge machine.Cane moves on to the left side along threshing cylinder, throws to the left front of machine under the effect of cylinder centrifugal force and cylinder Lysimachia sikokiana plate, is laid on the field piece that has gathered in.Like this, just finish harvesting, threshing, separated, clean, collected the integration of operation overall process of grain.

In Fig. 2, the drive sprocket (16) on the intermediate propeller shaft (26) is driven by the sprocket wheel on the cylinder (12), and crank (17) is coaxial with drive sprocket (16); When middle power transmission shaft (26) rotated, bearing pin drivening rod (18) on the crank (17) and bulb screw (19) made fork (20) do reciprocal oscillating motion around fork axle (21).

In Fig. 3, the end of moving knife riveted (23) is a sliding sash, and the sliding sleeve (24) in the frame groove is enclosed within on the bearing pin of fork (20), and sliding sleeve (24) has two sides and sliding sash cell wall for being slidingly matched; When fork (20) when doing reciprocal oscillating motion, sliding sleeve (24) drives moving knife riveted (23) and does reciprocating linear motion, and finishes the cutting action of moving knife.

In Fig. 4, collection tanker (33) is fixed on the power rack, and fan (36) is installed in the back of collection tanker (33), and crank belt pulley (32) is installed in the front of collection tanker (33); Screen box (40) has been hanged the oral area top that is hinged on collection tanker (33) by 3 poles (29) and rocking bar (37); Slide plate (27), shell sieve sheet (39), wire gauze sieve sheet (28) and garden hole sizer sheet (30) are housed in the screen box (40), and top sieve is made up of shell sieve sheet and wire gauze sieve sheet, and following sieve is a garden hole sizer sheet.Crank pin (31) is housed on the crank belt pulley (32), and an end of connecting rod (38) and rocking bar (37) are hinged, and the other end and crank pin (31) are hinged; When the powered pulley on the engine drives fan wheel (34) rotation, the small belt pulley coaxial with fan wheel (35) drives crank belt pulley (32) by bead apex and rotates, crank pin on the wheel (31) makes screen box (40) do reciprocal oscillating motion with crank belt crop rotation garden Zhou Yundong thereby drive rocking bar (37) by connecting rod (38).When combine during in farm work, through the grain once cleaned and a small amount of assorted surplus mixture through horizontal horizontal screw conveyor (5) with promote the charging aperture that screw feeder (10) is sent into screen box (40), on slide plate (27), scatter and the shell that flows into ground floor sieves above the sheet (30); Because the reciprocally swinging of screen box and the air-flow of fan (36) are carried, the light assorted surplus screen boxs that are blown such as grain husk shell, most of short cane is thrown by top sieve and is sent screen box, grain and a spot of short cane drop on down to be proceeded on the sieve to separate, grain falls into the collection tanker by hole, compass screen surface garden, short cane is sent screen box by throwing, cleans operation with regard to the secondary of having finished grain like this.
