Abstract
The present invention discloses a moveable threshing comb and a rice and wheat combine. The combine consists of a device ,a power device, an idler wheel and a driving means, the threshing comb is transversely mounted on the front of the device body, multi-rows of fixed combs and corresponding moveable threshing combs are equably installed on a rotating round end plate at both ends of a rotating shaft of the threshing comb board of the comb is an arc board forward radial extending, on a still round end plate of the comb, a means making the threshing comb and the fixed comb to shut or open when the threshing comb is rotated to a given position. The rotating shaft is connected to the power device by a transmission; there are many dial rods over a granule receiving box at middle-rear of the threshing comb, at same time, multi guiding rods extends forwardly at front-down of the threshing comb.
Description
Technical field
The present invention relates to a kind of rice and wheat crops harvest machinery, specifically is a kind of movable threshing comb and the direct threshing type rice wheat harvester that this comb is housed.
Background technology
Existing rice wheat harvester is of a great variety, and structure is different, but generally is to cut earlier afterwards to fail to take off again, and its structure is generally complicated, and volume is heavier, and cost is higher, and general peasant household is difficult to accept, and also not too is fit to fritter fields such as mountain area, hills and uses.The directly report of threshing type rice wheat harvester was arranged on the publication, but some deficiencies was separately all arranged, if any employing suction type principle, directly inhale rice wheat head grain with powerful vacuum, but volume is huger, it is bigger to consume energy, straw is too many, and the above-mentioned situation of incompatibility equally.The direct threshing of employing broach separating mechanism that and for example also has, performance is better than other harvester for both rice and wheat, but still have some shortcomings in the practice: 1, threshing comb is fixed, the gap of broach immobilizes, and the bar footpath that how much reaches straw of the rice wheat head changes, relief width take off unclean, the gap is narrow but the difficult straw that accurately inserts rice wheat head below in; 2, because broach is to be contained on the transverse bar of circumference point of major diameter roller, so the spacing distance on circumference is too big between broach and broach, and the process of its comb is owed continuously in practical operation, and it is more to leak the rice wheat head of combing; 3, its structure still seems complicated.
Summary of the invention
The technical problem that the present invention will solve is, overcomes above the deficiencies in the prior art, provides a kind of and can accurately insert straw, rice wheat comb can be taken off totally again, and is difficult for the movable threshing comb of the rice combing leakage wheat head.
Another technical problem that the present invention will solve is, overcome above the deficiencies in the prior art, provide a kind of and can accurately insert straw, the clean rate height of comb, be difficult for the rice combing leakage wheat head, and the direct threshing type rice wheat harvester that is widely used in mountain area, little field, hills that structure is simpler, volume is littler, cost is lower.
A technical solution of the present invention is; a kind of movable threshing comb is provided: it comprises fixedly nose circle plate of support and two; the circle at rotating shaft two ends revolves on the end plate and evenly is provided with the fixing comb of many rows around circumference; the comb panel is the circular arc panel that radially extends forward; with every row fixedly the activity that matches of comb shape shape comb horizontal sliding fit on fixing comb or/and lower surface, have on the quiet nose circle plate when the fixedly comb of threshing comb and movable comb rotate to ad-hoc location movable comb and fixing comb are closed up or open device.
Its main body of the plan view shape of the broach of described comb can be rectangle, and movable comb is or/and the dual-side of fixing comb broach can be established several little teeth, and its head can be triangle.
Another technical solution of the present invention is, a kind of direct threshing type rice wheat harvester that above-mentioned movable threshing comb is housed is provided, and comprises body, engine, roller and drive unit thereof; Described movable threshing comb is laterally hinged with (installation) front end at body, and the rotating shaft of threshing comb is connected with engine through gearbox; The middle rear of threshing comb is for connecing the grain bucket, and the body that connects grain bucket top is provided with the many axial retaining grain bars that match with the broach gap, and there are the many grain guiding rods that axially protract the front lower place of threshing comb.
The cutting mechanism of the straw after the cutting threshing can be established in the back lower place of threshing comb.
After adopting above structure, movable threshing comb of the present invention and direct threshing type rice wheat harvester that this comb is housed compared with prior art have following remarkable advantage and beneficial effect:
1, this movable threshing comb can be installed in the supporting with it use of front end of other harvesting machineries arbitrarily; also can be installed in the front end of other agricultural machinery; be equipped with uses such as grain receiving bucket; also can be assembled into the reaping machine (as this reaping machine) of a platform independent; because the gap of this movable threshing comb broach can be regulated automatically; threshing comb both can accurately have been inserted in the straw of rice wheat head below, can comb grain or wheat on the clean rice wheat head again, its threshing is satisfactory for result.
2, because the every row's broach of this movable threshing comb all is to be the footpath radiotropism to arrange from the axle center,, avoided the phenomenon of the rice combing leakage wheat head fully so the course of work of comb threshing is uninterrupted continuously.
3, because this direct threshing type rice wheat harvester is equipped with this movable threshing comb, so, except that having above-mentioned two advantages fully, its structure is very compact, simple, and its machine volume is very little, and is in light weight, cost is low, less energy consumption, common peasant household affords and affords to use, and is widely used in the little field on mountain area, hills.
4, this directly the dogstail of not cutting of threshing type rice wheat harvester can return the field and macerate mashed back as fertilizer sources; In the time of need cutting standing grain, load onto cutting mechanism of the present invention and get final product, this cutting mechanism is simple in structure, the cutting convenient power-saving, and long service life, it is low to consume energy, and this machine can satisfy different peasant households and cut and the different needs that do not cut.
