Abstract
The utility model relates to a combined harvester for beans and wheat, which belongs to a grain harvesting machine in agricultural machinery. A threshing cleaning assembly of the combined harvester for beans and wheat is formed by a funnel-shaped rice cleaning chamber composed of belt pulleys arranged coaxially, a threshing roller, a grass removing wheel, a fan and a left, a right, a front and a back side plates which are fixed on a machine frame, a wind sucking passage having a changeable cross section is matched with a wind riddle to clean grain, and a gap bridge conveyor belt of a conveying trough assembly is directly sheathed with the inner diameter of a vane of a packing auger of a header. The combined harvester for beans and wheat has the characteristics of simple structure, light weight, little loss of the header and conveyance, few operating faults and favorable cleaning effect.
Description
That the utility model belongs to is supporting for small four-wheel tractor, be used for crop harvesting, threshings such as soybean, wheat, paddy rice, clean the combining facility of operation.
Small four-wheel tractor is to use maximum, the maximum farm power machinery of recoverable amount in the agricultural production of present China, for giving full play to its effect, improve agriculture harvest operation mechanization level, for its supporting all kinds of beans wheat combining facility are widely used in the agricultural production, be subjected to peasant's welcome.But in existing beans wheat combine, ubiquity the complete machine structure complexity, weight is big, fault is many, the common fault of dependability difference, become a great problem for the supporting design of small tractor, for example the threshing on such facility partly all is made up of threshing cylinder, shake cleaning shoe, fan and the numerous and diverse transmission system of a cover, and none lacks; For another example, the cane before the threshing is not carried twice extruding of the belt chain harrow of flexible rake teeth of the screw feeder that has all adopted header and delivery chute, the mode that relay is carried, both existed baroque drawback, exist the excessive defective of the cereal ceding of Taiwan and conveyance loss again; In addition, the design of traditional air channel is prismatic on the facility, because the loss of wind-force in flowing in the air channel weakens wind speed gradually, has reduced the cleannes of cereal after the threshing.
The purpose of this utility model is exactly big, the relatively poor problem of cleaning effect of cereal loss in carrying at the implement structure complexity that exists in the prior art, cane, design a kind of beans wheat combine, reach the purpose of simplifying complete machine structure, reduction complete machine weight, the operation fault that reduces, raising cutting, conveying, threshing, cleaning effect.
Basic design of the present utility model is that this machine is made up of header assembly, delivery chute assembly and threshing and cleaning assembly.On the threshing and cleaning axle, installing the threshing and cleaning belt pulley simultaneously, threshing cylinder, grass-removing wheel and fan, notch board is configured in the threshing cylinder below, be fixed on the left side on the frame, right, before, back side panel is formed funnelform cleaning unit, and integral body is positioned at the notch board below, at the lower end of left plate connection wind riddle, the upper end exhaust outlet that is fixed on the variable cross-section air draught road on fan drum and the frame is communicated with the air inlet of fan, inlet scoop, lower end and wind riddle coupling, triangular driving band is connected main drive belt wheel and threshing and cleaning belt pulley, so far constitutes the threshing and cleaning assembly of this machine; The air draught road cross-sectional area of variable cross-section is evenly reduced gradually by inlet scoop, lower end to upper end exhaust outlet; Three grain lifters are installed on the header assembly; The gap bridge conveyer belt front end of fixing the rake teeth that extends of delivery chute assembly directly is sleeved on the screw feeder blade interior diameter of header assembly.
The utlity model has complete machine structure simple, in light weight, save that steel, operation fault are few, the ceding of Taiwan and conveyance loss is little, the threshing cleaning effect is good characteristics.

Fig. 2 is a threshing and cleaning assembly structure schematic diagram;
Fig. 3 is the side direction view of Fig. 2;
Fig. 4 is grain lifter installation site schematic diagram on the header assembly;
Fig. 5 is gap bridge conveyer belt and screw feeder assembly structure schematic diagram.
Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.The beans wheat combine is assemblied by header assembly 1, delivery chute assembly 2 and threshing and cleaning assembly 3.On threshing and cleaning axle 7, installing threshing and cleaning belt pulley 6 successively, threshing cylinder 8, grass-removing wheel 9 and fan 10, notch board 11 is configured in the below of threshing cylinder 8, and notch board 11 can be realized and threshing cylinder 8 between the cylinder-concave clearance adjustment, left plate 12, right plate 13, front side board 14, back side panel 15 all is fixed on the frame 16, form funnelform cleaning unit 23, these cleaning unit's 23 integral body are positioned at the below of notch board 11, wind riddle 18 in the connection of the lower end of left plate 12, and communicate with row's grain mouth, shell and 17 its upper end exhaust outlets of the air draught road on the frame 16 of being fixed on fan 10 are communicated with the air inlet of fan 10, inlet scoop, lower end and wind riddle 18 are complementary, triangular driving band 5 is sleeved on main drive belt wheel 4 and the threshing and cleaning belt pulley 6, so far constitutes the threshing and cleaning assembly 3 of this machine.Air draught road 17 cross sections are the variable cross-section shape of even transition from bottom to top, are promptly reduced gradually by the inlet scoop of the lower end exhaust outlet cross-sectional area to the upper end.Three grain lifters 19 are installed on header assembly 1, and the furrow central lines in the middle of the center line of middle grain lifter 19 and the two ridge platforms.Gap bridge conveyer belt 21 front ends of delivery chute assembly 2 directly are sleeved on the screw feeder 20 1 side screw feeder blade interior diameters of header assembly 1, are fixing lengthening rake teeth 22 on gap bridge conveyer belt 21.
During harvest operation, after header assembly 1 will cut down gap bridge conveyer belt 21 experience that the cane that has grain utilizes screw feeder 20 and have a rake teeth 22 that extend and once push, send in the threshing and cleaning assembly 3 through delivery chute assembly 2 again, the threshing cylinder 8 of rotation cooperates with notch board 11 to be taken off grain from cane, grain after taking off and assorted surplus grade are from notch board 11 falls people cleaning unit 23, and the cane after the threshing is discharged threshing cylinder 8 by grass-removing wheel 9.Grain and assorted surplus left, right, front and rear side plate 12,13,14,15 surfaces along inclination glide with certain thickness and flow velocity, in the time of on arriving wind riddle 18, assorted surplus by variable cross-section air draught road 17 and fan 10 siphons away and the eliminating machine outside, grain is then discharged pack by row's grain mouth.
