Abstract
A high speed harvesting apparatus of harvester of the utility model belongs to an agricultural machinery field. The apparatus is suitable for the using of a harvester. The major technique of the utility model is that a throwing material board on a first allocation packing auger is opened with a breach. A screw leaf of the first allocation packing auger is provided with two tube reducing plane segments. A throwing material board on a second allocation packing auger is opened with four breaches. A screw leaf of the second allocation packing auger is provided with a tube reducing plane segment. Two of four ribbed boards on a movable rack concave board are respectively opened with two circular arc grooves. One of the other two ribbed boards is opened with a circular arc groove. A limit striker board is made to be rigid. The major advantages of the utility model are: the model can be suitable for the harvesting of the dried rice straws. The loss rate of the grains of the rice is from 0. 5% to 1% and the loss rate is much lower than the loss rate required by the country. In addition, the clean degree of the grains of the rice is high.
Description
One, technical field
The utility model belongs to agricultural mechanical field.
Two, background technology
Existing 2A type, the self-propelling grain header of 2.5A type got extensive use in the rice wheat harvest aspect cutting, but these types all come with some shortcomings aspect harvesting, and first deficiency is: when gathering at a high speed, cause machine to stop up easily, can not normally move.Second deficiency is: can cause serious seed loss when gathering at a high speed, it is more to produce the impurity that contains in the millet in addition, makes millet unclean.These deficiencies all are unreasonable the causing of structural design by the scope of activities of movable grid concave plate and the striker plate of limiting the quantity of, and therefore will design again the scope of activities of the movable grid concave plate of existing grain header and the structure of the striker plate of limiting the quantity of.
Three, technology contents
The purpose of this utility model is exactly to design a kind of high speed reaping apparatus of grain header, has both adapted to dry rice straw harvesting, the rice straw harvesting that the humidity that can suit again is higher.The utility model major technique is: open a gap on the first material casting plate that distributes on the screw feeder, the section of scabbling that two place's tube reducings are arranged on the spiral leaf of the first distribution screw feeder, on the second material casting plate that distributes on the screw feeder, open four breach, the section of scabbling that one place's tube reducing is arranged on the spiral leaf of the second distribution screw feeder, respectively have two garden arc flutings on two gussets on movable grid concave plate in four gussets, have a garden arc fluting on a gusset, the striker plate of limiting the quantity of is made rigidity.The utility model major advantage: can adapt to the high speed harvesting of drying of rice straw, the requirement of the low what national regulation of the seed percent of loss of millet, the seed cleanliness of millet is good.

Five, embodiment
Describe details of the present utility model and working condition in detail in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5.The rice wheat of harvesting will threshing in movable grid concave plate (5), the position of movable grid concave plate, just opening degree is controlled by handle (18) and lever (17), on the movable grid concave plate four gussets (6) are arranged, wherein there is tibet cinnamon bark plate and first to distribute the screw feeder (1) and the second material casting plate (3) that distributes on the screw feeder (2), (4) and first distribute screw feeder, spiral leaf (19) on second screw feeder has interference, influenced the opening degree of movable grid concave plate, make opening degree not increase, thereby reduced the harvesting speed of grain header, when particularly the rice straw is dry, harvesting speed height, understand and beat the rice straw to such an extent that mistake is morcelled little, influenced millet and raised only, so grain header can only move under lower-speed state.In order to increase the opening degree of movable grid concave plate (5), adapt to harvesting at a high speed, on the first material casting plate (3) that distributes on the screw feeder (1), open a gap (14), the section of scabbling (13) that two place's tube reducings are arranged on the spiral leaf (19) of the first distribution screw feeder, on the second material casting plate (4) that distributes on the screw feeder (2), have four breach (14), the section of scabbling (13) that one place's tube reducing is arranged on the spiral leaf (19) of the second distribution screw feeder, respectively have two garden arc flutings (16) on two gussets (6) in last four gussets of movable grid concave plate (5) (6), on a gusset (6), open a garden arc fluting.On the movable grid concave plate four gussets (6) are arranged, only on three gussets that interference arranged, open garden arc groove (16), do not have just no longer to have opened garden arc groove on the gusset of interference.The utility model is in order to reduce the loss of millet, and the striker plate of limiting the quantity of (8) is made rigidity.The striker plate of limiting the quantity of that grain header is original is flexible, and the striker plate of limiting the quantity of of this flexibility can not be controlled the charging of wanting well sifted rice wheat material equably, this material is meant through rice straw and rice wheat after the friction, so the striker plate (8) of limiting the quantity of is made rigidity.In order to control inlet amount better, the lower end of the striker plate of limiting the quantity of (8) connects a rectangle portable plate (11) with hinge (12), and the lee face in the striker plate of limiting the quantity of (8) is fixed a gag lever post (10) on grain header wallboard (20).The striker plate because limit the quantity of (8) is to hang on handle (18) axle (7) with ring (9), striker plate can freely swing so limit the quantity of, simultaneously connected a rectangle portable plate (11) with hinge (12) in the lower end of the striker plate of limiting the quantity of, a gag lever post (10) has been installed again simultaneously, so it is even relatively that inlet amount can reach, reduce the compass screen surface load, thereby can make the millet choosing clean, avoided excessive, caused the millet screening not cause damage only because of inlet amount.Distributing screw feeder (1) and second to distribute on the screw feeder (2) first all is equipped with material casting plate (3), (4), has done reinforcement (15) on material casting plate (3), (4).This reinforcement (15) is to prevent that the distortion of material casting plate (3), (4) is set.
Claims (3)
