Description
The utility model relates to the agricultural machinery that the rice wheat harvest obtains Work machine.
At present, the type and the negligible amounts of the rice combine promoted the use of of China south rice district.That has promoted the use of mostly is four-wheel tractor, or joins extension with cterpillar drive, and the combine of two-wheel or the supporting walking of one-wheeled tractor is seldom seen use.
The horizontal ceding of Taiwan that the four-wheel tractor of having promoted is worn is cut all feeding-in combine of stubble based on height, leaves the higher stubble that cuts after the operation, is unfavorable for small hand tractor tractor-ploughing operation, also is unfavorable for gathering in back sowing, and use is difficult in southern rice district.The low cutting stubble half-feeding combine employing crawler unit that has or two-wheel walking is the former thereby large-scale popularization not because of mechanism's complex work poor reliability etc. also.With the combine of domestic existing small hand tractor supporting (hand tractor do not do to change or change very less and supporting), not seeing so far has the popularization of coming into operation of reliable type, and its reason has:
1, hand tractor has been carried out bigger change after, as the supporting combine of chassis special, lost the advantage of a tractor serves several purposes.The combine of supporting like this one-tenth, more harm than good on the contrary.
2, adopt the walking tractor matching of two-wheel walking after, the weight of fixed harvesting, threshing unit all is carried on the walking iron tyre, make the walking iron tyre difficulty in walking that cause that sink more, the difficulty place that this has just become many places, various places for many years to succeed.For this reason, the multidirectional crawler type development of the running gear of rice combine.
On the workpiece of combining, the height of the horizontal ceding of Taiwan cuts a batch mode operation, though advantage is arranged, but its shortcoming is outstanding, become the key that is difficult to promote, recently it is supporting in four-wheel tractor that also there is research secondary cut mode various places, but since it exist the conveying of fringe portion after cutting cross in the adaptability problems of the serious and different height crops of cereal loss.
The purpose of this utility model provides a kind of small-sized rice/wheat combine of suitable southern rice district's operation.
1, do not changing or changing less under the existing hand tractor structure situation as far as possible, can join easily and hang up harvesting and threshing, collection grain parts, finishing the integration of operation of rice wheat, making tractor reach a tractor serves several purposes.
2, make this machine that adaptability more widely be arranged when farm work and the transfer of field piece---in stiff Udoll ground, adopt iron tyre walking energy reliably working, make its handiness flexible.
The novel purpose of this reality is such realization:
The principle of master-plan is, the distribution of weight of complete machine, born by ground and running gear respectively, overcomes the unreasonable design by the whole load-bearing of running gear.Promptly adopt by hand tractor walking iron tyre and drive the tractive force that produces, except that himself walking, the grain header that a part slides with being used for promoting forward to paste, another part are used for the dilatory backward collection grain device that lands and slide.Because the weight of header and collection grain device (comprising cereal) is by ground supporting, like this, iron tyre sank dark in the time of can not causing paddy-field-working because of its load-bearing is excessive, as long as iron tyre just can adapt to operation at its driving tractive force that sink and can provide within the specific limits.Generally speaking, the farming iron tyre of hand tractor adapted all can meet the demands.
Certainly its weight of collection grain device that tows behind header that pushes away before and the wheel is big more, the tractive force that needs tractor to provide is also big, this just need make the weight of header and collection grain device alleviate from design as far as possible, need the walking iron tyre that the big driving force of trying one's best is provided, thereby further improve the adaptability of whole unit in the paddy field.
Because the weight of header and collection grain device is by ground supporting, the beam frame structure that they are connected with hand tractor thereby also can simplify helps alleviating of complete machine structure weight, so also helps this machine combination property raising.
The weight of header is born by ground, even the ceding of Taiwan floats on the face of field, tractor walking iron tyre is let alone to sink to end sand ground soil, promptly allows iron tyre sink, and this design principle is at floating type paddy field harvester for both rice and wheat---and accomplished in the design of patent No. 91.217676.8.---adopt iron tyre walking promotion header to be close to the field face and slide.This machine then is on floating type grain header basis, how harvested straw is carried and is carried out threshing, collection grain and realize integration of operation.
Promptly on the harvester for both rice and wheat basis, floating type paddy field of patent No. 91.217676.8, having adopted and installed the pressure of carrying out secondary cut additional, cut, fed fringe head unit (3), (seeing accompanying drawing 1) fringe head delivery chute (7) and sheller unit (10) collection grain device (11) has been made up of the vertical type reaper platform (1) that floats and has carried out crop root cutting, feed fringe head unit (3) by crush-cutting again, delivery chute (7), sheller unit (10) collection grain device (11), finish cutting fringe head, carry fringe head and threshing, the combining unit of the harvesting of collection grain, threshing integration of operation simultaneously.Crop is after root and fringe portion process secondary cut, and remaining bottom cane is emitted on the side field face by transverse onveyer in the vertical type reaper platform (1).Like this, remain cane behind the unit operation at the field face, but peasant household's disposable, handle in the field of doing also that has, unnecessary, artificial take fortune after, help farming of following season or sowing.
The technical solution of the utility model is:
Side top at vertical type reaper platform (1), be provided with power take-off (12), have the pressure fringe bar (6) that the crank rotation drives, and disc cutter (4), feed the pressure that fringe dish (5) is formed, cut, after hello fringe head unit (3) is sleeved on the power take-off (12), under their rotation, straw after by standing header (1) the crop cane being cut for the first time from root, in its horizontal process, earlier by pressing fringe bar (6) that the fringe head is pressed down, that finishes cutting fringe head by round cutting-off tool (4) again and feed fringe dish (5) feeds the fringe head, makes the fringe head enter the import department of fringe head delivery chute (7) rapidly.At this moment, the scraper plate that has in the Synchronous Transmission conveyer belt in opening straight formula fringe head delivery chute (7) carries out threshing from the bottom scraping delivery of groove with the fringe head of import department immediately to sheller unit (10).Grain enters collection grain device (11) after the threshing, and the assorted surplus other end from sheller unit (10) in the threshing is discharged voluntarily, and operating personnel can get fortune cereal from collection grain device (11).
Cut the fringe action reliably for high speed rotating disc cutter (4) is finished, it also must have corresponding ledger-plate to support, and ledger-plate is arranged on the relative position of disc cutter (4) cutting edge.The effect of feeding fringe dish (5) is to feed rapidly to the import department of (7) for the fringe head that downcuts (no matter short or long fringe head).When the installation of disc cutter (4) and hello fringe dish (5) is exchanged, (be that power take-off (12) locates to install disc cutter (4), originally the position of dress disc cutter (4) changes the outfit and feeds fringe dish (5)), disc cutter this moment (4) just have cutting and feed two kinds of fringe cut can, feed fringe dish (5) and then play the effect of holding up fringe---the fringe head is held up cutting edge place to disc cutter (4).The angle of the cutting edge of disc cutter this moment (4) and corresponding ledger-plate should be changed.
For making the fringe head after the secondary cut, neither too short, not long again.Crush-cutting is fed the height of fringe head unit (3) on header (1) should be adjusted in the appropriate location.It is realized by height regulating rod (8).
Because crush-cutting is fed fringe head unit (3) and is fastened on the standing header (1), and the connecting rod (15) of connection standing header (1) on tractor and the angle (α) on ground, it waits with whether sinking of iron tyre (2) and changes, so fringe head delivery chute (7) can not be fastened on crush-cutting and feed on the device (3), it must freely rest the top that crush-cutting is fed device (3), before and after the energy, about do an amount of moving, because crush-cutting is fed device (3) and is wanted height up and down, so the other end of fringe head delivery chute (7) is the hinge structure, delivery chute (7) can be swung up and down, the pin joint of this swing, the fixed cover of the bearing block of the power input shaft by delivery chute (7) realizes, inserts jack (9) in the sheller unit (10) with the fixed cover of this bearing block, and delivery chute (7) and sheller unit (10) are linked together.Because the other end of delivery chute (7) freely rests crush-cutting and feeds on the device (3), so corresponding baffle plate and sealing and adjusting device thereof must be arranged in the porch of delivery chute (7), neither stop up, do not make the outside leakage loss of grain again, guarantee the normal operating conditions of fringe head in delivery chute (7) porch.(seeing accompanying drawing 2), the front end of fringe head delivery chute (7) rests crush-cutting and feeds on the base plate of the back lower place of device (3), the prolongation of the sheet rubber (19) of the lower plane that is fixed in crush-cutting hello device (3) is inserted in the porch of delivery chute (7), it is positioned between the base plate of the scraper plate (20) of conveyer belt and delivery chute (7), and guarantee between sheet rubber (19) and the conveyer belt scraper plate (20) certain interval (δ) is arranged, big I (δ) is reached by gap adjustment plate (21), makes the fringe head of feeding (7) import department can in time enter conveying.
The fringe head is after sheller unit (10) effect; grain comes together on the collection grain device (11) that tows that lands, and goes into bag (frame) or directly sends into bag (frame) by the device of delivering grain that horizontal auger in the sheller unit (10) and vertical auger (not marking among the figure) are formed and transport with manually scoop up out cereal with a dustpan from collection grain device (11).The artificial cereal of scooping up with a dustpan must be shut down before the edge of a field turns to and carried out, and shuts down the artificial fortune of scooping up with a dustpan, has taken the working time to have reduced effect, but simple in structure, processing cost is low, and fault is few.Adopt motor-driven auger to send paddy to go into bag, mechanism's complexity, cost height.
Collection grain device (11) is to be connected Xiao (17) by level to connect together with sheller unit (10), sheller unit (10) is connected with Xiao Zi with the traction frame of tractor rear end by link (18) again, and the Xiao Zikong of the other end of sheller unit (10) and tractor handle bar is linked to be an integral body.Collection grain device (11) is articulated in sheller unit (10) by horizontal Xiao Zi (17) and goes up and slide against in tow on the face of field.
When field transfer or farm work backward, collection grain device (11) can make collection grain device (11) rise, thereby have field trafficability characteristic (or backward) more widely by the hook of the suspension hook (chain sling) (16) on being located at thereafter on the tractor handle.
For crossing short or too high crop, when this unit was difficult to adapt to operation, removal pressed, cut feed fringe head unit (3) and fringe head delivery chute (7), sheller unit (10), collect grain device (11) after, also can become the harvesting unit separately.
Because this unit adopts Xiao Zi to articulate mode, mounting or dismounting are convenient, are particularly suitable for the existing hand steered supporting use of model machine of dragging of peasant household.
