Description

A kind of multipurpose miniature rice combine

The present invention relates to a kind of agricultural machinery product, is a kind of whole multipurpose miniature rice combine-harvester that gathers in and can plough specifically.

Combine is practical in a large number in northern wheet-producing area, still fails large tracts of land to use in the south rice producing region, and the harvesting paddy rice is still adopted traditional manpower mode, not only labour intensity is big, the cost height, and efficient is low, the double cropping rice producing region also often will miss the farming season, and causes the late rice underproduction.Trace it to its cause, the one, the paddy field field piece in south, particularly mountain area is little, is uneven, the 2nd, water or sposh are arranged in the rice field, the large and medium-sized combine that body is big, heavy can't be put its ability to good use.

The objective of the invention is to: provide that a kind of volume is little, in light weight, purposes is many, low-cost multipurpose miniature combine harvester,, alleviate peasant's labour intensity, raise labour efficiency to adapt to whole, the harvesting of ploughing of south or mountain area paddy field.

The object of the present invention is achieved like this: design comprises the rice cutter of base and base front portion, the thrasher at middle part, pressure standing grain device, gearbox, driving wheel, the engine directive wheel at rear portion and the miniature combine harvester of operating means, be characterized in: 1. base is a hull shape, the middle part of hull is fixed with gearbox, the rear portion is fixed with put-put, the two ends of output shaft of gear-box are fixed with Pu roll-type road wheel, the output shaft of this engine is after gearbox slows down, and two Pu roll-type road wheels that drive midship are realized advancing or retreating.The front end of hull shape base is fixed with the cutter up and down of the continuous serration of clip formula and blocks the rice cutter that the standing grain device is formed by nut and connecting rod, make behind the gear-box of the power of engine through a pair of worm gear, worm screw are arranged and block from left to right and the from right to left rotation of standing grain device, straw is cut off, and make the rice bar by the rotation from left to right and from right to left of the drum belt on the worm-wheel shaft by blocking the standing grain device, be delivered to thrasher and carry out threshing.2. be provided with up and down two thrashers that the threshing rolls wheel is formed at the middle part of hull base, be provided with left and right two belt pulleys in that thrasher is other, have belt pulley that the soft roller and the rigid plastics roller of spring are arranged in driving, composition can push down the pressure standing grain device that the rice bar carries out threshing.

Advantage of the present invention is: 1. because of support is a hull shape, afterbody is provided with steering wheel, and the hull middle-end is provided with roll-type driving wheel in Pu on two, thus this machine both can be in the nonirrigated farmland, do the field, also can be in the paddy field or wet field advance, finish the harvesting operation.2. simple in structure because of this machine, volume is little, and is in light weight, detachable and easy to assembly.3. can advance because of this machine or moving back, harvester also can be dismantled, and after laying down rice cutter, hangs up that plow harrow can be ploughed or whole field, realizes a tractor serves several purposes.

Introduce a tool embodiment below in conjunction with accompanying drawing:

Fig. 1 is the subjectivity figure of structural representation of the present invention;

Fig. 2 is the back sight figure of structural representation of the present invention;

Fig. 3 is the vertical view of Fig. 1.

With reference to accompanying drawing: be fixed with the cutter (2) of the continuous serration of upper and lower clip formula with nut in the base front portion of hull (1), connecting rod (3) is equipped with at the rear portion of cutter (2), holds up the standing grain star-wheel near cutting to add by bolt on the hull front end.(4), (5), (6), (7) are respectively held up on the fixed axis of standing grain star-wheel and the front end of hull both sides, be provided with nearside divider (8), (9), (10), (11), (12), (13), middle part at the hull front end is fixed with worm gear, the worm tooth roller box be used for driving (14), (15), (16), (17) make (14), (15) by upper and lower conveyer belt (18) by side-to-side movement, (16), (17) pass through upper and lower conveyer belt (18), motion from right to left.At fore-body another worm gear is housed simultaneously, the worm tooth roller box is used for driving transportation (49), (50) and connecting rod (3).

Fore-body is left and right respectively to be equipped with (19) and (20) two driving wheels.On the axle of two driving wheels, (21) and (22) two kinks are housed, are used for and hull connection and the mechanism that can make the hull lifting is housed.In the middle of the axle of two driving wheels, differential mechanism (23) is housed, goes up chain chain wheel (27) and drive, hull is marched forward by worm gear, worm tooth roller box (51).Simultaneously, having an action bars (28) to be used for controlling hull on the gear-box advances, retreats.Another sprocket wheel (47) of gear-box (51) be used for driving (48) thus drivening rod (3) and travelling wheel (49), gear-box (51) worm screw (44) is driven by the sprocket wheel (30) on another worm gear, the worm tooth roller box (32), sprocket wheel (44) is double-stranded wheel, can drive the wheel (45) of thrashing in addition.Dental forceps clutch on the gear-box (32) by action bars (26) thus control makes complete machine work.Two-groove belt pulley on the gear-box (33) is driven by the two-groove belt pulley (35) on the diesel engine (34).Gear-box (51) and (32) are fixed by bolts on the hull, steering wheel (24) is housed at the middle part of hull, one direction machine (25) is housed under the steering wheel, can makes the directive wheel (36) of hull back rotate 90 ° to the left or to the right by connecting rod (52), thereby complete machine is turned to the left or to the right.Seat (29) is housed in the back of steering wheel.The wheel (42) of thrashing is housed on the right side of midship, is driven by (45), right side of face has two pairs of belt pulleys (49), (50) and (40), (41) to be used for driving conveyer belt (54) and (53) wheel (42) under thrashing, make the rice bar uprightly also forward by after move.Be equipped with a relevant place of spike of rice in the middle of (53), (46) are used for spike of rice slowly is depressed into 45 °, and spike of rice are entered thrash wheel, and go out (56) from the exit, thereby finish the operation of thrashing.Be equipped with in the centre of conveyer belt (53) in addition and press standing grain device (43), in establish spring mechanism, thereby can make the front to the incompetent thick or thin rice bar tightly can both being pushed down of rice bar afterwards, the unlikely wheel (43) of being thrashed pulls away the rice bar and smoothly grain is taken off, the grain of taking off falls on the following elevating belt (39), fall into grain holding bucket (38) again, in the snakeskin band (37) of packing at last.Belt pulley (55) on the elevating belt (39) is driven by worm gear, the worm tooth roller box (can't draw) below (40).The intact straw of threshing is transported to outside the hull by (40) and (41).And fitly fall in the rice field of having cut.Overall structure all connects with bolt and nut, and hull is by angle bar and iron plate welding.

This machine will cut and set up plough after rice and sheller unit are pulled down, harrow, rolls, and can plough whole paddy field, carry out a tractor serves several purposes.
