Abstract
The invention relates to a grain combine harvester. The invention adopts the axial flow assembly which is coaxially arranged and has the functions of propulsion, separation, vertical separation and cleaning after the grains are cut by the ear of the vertical header, and the axial flow assembly and the concave plate screen are conveyed and cleaned to form a compact whole and are hung on one side of a tractor or a multipurpose chassis. Thereby simplifying the complex middle conveying mechanism of the combine harvester, saving power and reducing use cost.
Description
The invention relates to the combine of cereal mechanized harvest.Now paddy rice, combined wheat harvester, general adopt with the ceding of Taiwan, middle conveying plant, threshing unit be arranged in tractor or multi-purpose chassis before, during and after the position so that mechanism's complexity, loose, use cost height.Even picture Foshan type half-feeding combine tries hard to hang over tractor reducing cost with cutting, send, take off three big workpieces, but also because of the inconvenient abundant use that influences tractor of dismounting.Chinese patent CN85102442U has announced a kind of " the rice wheat is upright results and carries flow process and machine thereof ", though significant improvement has been arranged, also needs configuration engine in addition, thereby can not make full use of tractor, and increased cost.
The purpose of this invention is to provide a kind of new grain combine, at first design one pre-small post-large, low early and high after axial flow combination roll, carry, clean the composition one under itself and the concave grate, join and hang over tractor or multi-purpose chassis one side, and cut, send, take off three big steps and need not to dispose in addition engine, thereby can make full use of tractor or multi-purpose chassis, reduce the results use cost.
The purpose of this invention is to provide a kind of new grain combine, at first design one pre-small post-large, low early and high after axial flow combination roll, carry, clean the composition one under itself and the concave grate, join and hang over tractor or multi-purpose chassis one side, and cut, send, take off three big steps and need not to dispose in addition engine, thereby can make full use of tractor or multi-purpose chassis, reduce the results use cost.
Grain combine of the present invention, comprise grain lifter, the ceding of Taiwan, straw shift wheel, threshing cleaning unit, set gradually propeller, hulling disk and separation barrel after it is characterized in that on same axle by forward direction, and it is contained in the pre-small post-large cylindrical casing the tilting low early and high afterly side at tractor or multi-purpose chassis.The case that is in hulling disk and separation barrel below is a concave grate, and it has the grain conveyer belt of a closure.Side at separation barrel is provided with a dogstail outlet.
Roll the rear of letter in axial flow combination, the coaxial dust absorption fan that is provided with, this blower fan are contained in the guard shield, are provided with an air outlet in a side of guard shield, and the earthing is provided with an air inlet with putting out cereal mouthful mutually in the lower end of guard shield and cereal conveyer belt rear end.Thereby the cereal on the conveyer belt before the outlet pack, is further cleaned.
Fig. 1 is the embodiment of the present invention front view
Fig. 2 is the vertical view of structure diagram of the present invention
Fig. 3 is the end view of axial flow combination roll structure diagram of the present invention
Fig. 4 is the BB cutaway view of axial flow combination roll structure diagram of the present invention
Realize that a kind of better mode of the present invention sees Fig. 1: in a side of small four-wheel tractor (20), axial flow combination roll of the present invention (21) is tilted fixing by front bumper and trailing wheel bearing support (23), join extension one standing header (1) in the place ahead of four-wheel tractor (20), its power and four-wheel tractor flywheel are complementary.The power resources of grain conveyer belt (10) that are arranged on cylinder below are in four-wheel tractor driving wheel (19).Axial flow combination roll axle (22) is through universal joint (14), belt pulley (15), intermediate propeller shaft (16), by four-wheel tractor power take-off (17) transmission.
As shown in Figure 2: the front end of axial flow combination roll (21) is connected with standing header (1) through casing (3), and makes straw-poking star wheel (2) that cut substrate is dialled in smoothly.Axial flow combination roll (21) is by coaxial spiral propeller (4), internal lobe formula hulling disk (6) and the spiketooth type separation barrel (7) of being provided with behind the forward direction, and be contained in the pre-small post-large cylindrical casing (25), be provided with a dogstail outlet (8) in a side of separation barrel (7).
Shown in Fig. 3,4: the case that is in hulling disk (6) and separation barrel (7) below is a concave grate (9), and it is provided with the grain conveyer belt (10) of a closure down by conveyer belt guard shield (18).Rear in axial flow combination roll (21), with the coaxial cleaning fan (11) that is provided with of drum shaft (22), should be contained in the guard shield (24) by interior machine, its air inlet (25) communicates with the end of conveyer belt (10) and put out cereal mouthful (13), and its air outlet (12) is located at a side of guard shield (24).
The workflow of embodiment of the present invention is:
After standing header (1) cuts the cereal fringe down, be delivered to the ceding of Taiwan one side, dial in connection casing (3) by straw-poking star wheel (2), enter propeller (4), be pushed into hulling disk (6) through straw deceleration guide plate (5), a large amount of seeds are taken off, enter again that separation barrel (7) is defeated to help threshing, at this moment, straw is discharged from outlet (8), and the conveyer belt (10) of seed below concave grate (9) enters transported to the rear end, cleans through cleaning fan (11), impurity is discharged from air outlet (12), and grain is discharged pack from put out cereal mouthful (13).
The present invention compared with prior art has following advantage:
1, simple in structure, compact, simplified and carried in the middle of complicated Mechanism;
2, coaxial setting has propelling, threshing, separates and cleans function The axial flow assembly, thereby reduced use cost, saved power.
3 applicable to a harvest operation of kind crop.
Claims (1)
- A kind of grain combine, comprise grain lifter, the ceding of Taiwan, straw shift wheel, threshing cleaning unit, it is characterized in that threshing cleaning unit is the pre-small post-large axial flow combined type cylinder of diameter, be obliquely installed in low early and high after mode, be provided with propeller successively after by forward direction on same axle, hulling disk and separation barrel are below hulling disk and separation barrel, be provided with closed grain conveyer belt, the coaxial cleaning fan that is provided with by concave grate at the rear of axial flow combination roll.
