Abstract
The invention relates to agricultural machinery, in particular to a separation unit for a rice-wheat combine harvester. The separation unit for a rice-wheat combine harvester comprises a separator which is composed of a discharging port arranged at the top end of a casing, a fine fodder outlet arranged at the bottom end of the casing, a coarse fodder inlet arranged on the casing wall opposite to the fine fodder outlet, and a dirt raising fan arranged on the middle upper part of the casing, wherein the coarse fodder inlet of the casing is butted with a fodder discharging port on a threshing box; the dirt raising fan is connected to the side wall of the casing adjacent to the coarse fodder inlet through the singe side of a bearing, and a shaft of the dirt raising fan is directly connected with a power-output shaft sprocket wheel or belt on the threshing box. Due to the structure, the separation unit for a rice-wheat combine harvester has the advantages of high work efficiency and less loss of kinetic energy; and the separation unit can regulate amount of wind and variation of speed as required, and can also reduce use cost.
Description
Technical field
The present invention relates to agricultural machinery, the particularly a kind of separation unit for rice-wheat combine harvester that can increase work efficiency.
Background technology
Along with development of social productivity, miniature agricultural is popularized gradually with machinery, and the hilly country rice/wheat combine is particularly universal in China.Yet rice/wheat combine in use, and stalk is kept in motion and is easy to be cut off by separating tooth in the threshing case, produces short and small standing grain bits and enter appearance grain vessel, thereby increased peasant's the amount of labour.For reducing peasant's the amount of labour; rice/wheat combine in the market is to connect a separator in the exit that breaks away from case by drainage line; by separator short and small standing grain bits are separated with grain or wheat, thereby reduced peasant's the amount of labour to a certain extent.But the separator of prior art in use, and grain or wheat need pass through drainage line, and this has just reduced operating efficiency; The separator of prior art generally can not be regulated air quantity as required, and short and small standing grain bits are easy to be wrapped on the blade of airborne dust fan, finally cause the purpose that it can not the airborne dust deslagging, when making kinetic energy loss, also need to work after removing, further reduced operating efficiency being wrapped in standing grain bits on the blade of airborne dust fan.
In sum, the deficiency of the rice/wheat combine separator of prior art existence is: kinetic energy loss is big, inefficiency.
Summary of the invention
The objective of the invention is provides a kind of high efficiency and kinetic energy loss little in order to overcome the prior art above shortcomings, can also regulate the separation unit for rice-wheat combine harvester of air quantity and speed change.
The technical solution used in the present invention is such, it is a kind of separation unit for rice-wheat combine harvester, comprise by the coarse fodder import that is provided with on the outlet of the fine fodder of slag-drip opening that is arranged on the housing top and lower end, the housing wall relative, the airborne dust that is arranged on the housing middle and upper part and fan the separator of forming that wherein: the coarse fodder import of described housing is docked with discharge gate on the threshing case with the fine fodder outlet; Described airborne dust fan pass cross bearing monolateral be connected with coarse fodder import adjacent housings sidewall on, the axle of airborne dust fan directly be arranged on the threshing case on power take-off sprocket wheel or belt be connected.
In the said structure: the housing wall relative with the airborne dust fan is installed is provided with the bypass exhaust duct, and the two-port of bypass exhaust duct is communicated with formation deslagging air channel respectively with fine fodder outlet and slag-drip opening.
The bottom of described housing is provided with sieve plate.
Be provided with change-speed gearing or gearbox between the axle of described airborne dust fan and the power take-off.
Be connected with inserting groove on the housing at described fine fodder exit position place, be provided with in the inserting groove regulate air quantity insert-connecting plate.
Described inserting groove bottom is concordant with fine fodder outlet bottom, and the upper end is higher than fine fodder outlet top.
The advantage that the present invention has owing to said structure is conspicuous: high efficiency and kinetic energy loss are little, can regulate air quantity and speed change as required, can also reduce use cost.
Description of drawings
Said structure of the present invention can further specify by the non-limiting embodiment that accompanying drawing provides.
Accompanying drawing is a structural representation of the present invention.
In the accompanying drawing: 1, separator; 2, housing; 3, airborne dust fan; 4, coarse fodder import; 5, fine fodder outlet; 6, sieve plate; 7, discharge gate; 8, inserting groove; 9, insert-connecting plate; 10, power take-off; 11, bypass exhaust duct; 12, slag-drip opening; 13, threshing case.
Embodiment
The invention will be further described below in conjunction with drawings and Examples:
Referring to accompanying drawing, separation unit for rice-wheat combine harvester among the figure, comprise by the fine fodder of slag-drip opening 12 that is arranged on housing 2 tops and lower end outlet 5, export the coarse fodder import 4 that is provided with on 5 relative housing 2 walls with fine fodder, the airborne dust that is arranged on housing 2 middle and upper parts is fanned 3 separators of forming 1, wherein: the coarse fodder import 4 of described housing 2 is docked with discharge gate 7 on the threshing case 13; Described airborne dust fan 3 by bearing monolateral be connected with coarse fodder import 4 adjacent housings 2 sidewalls on, the axle of airborne dust fan 3 directly be arranged on threshing case 13 on power take-off 10 sprocket wheels or belt be connected.
In the said structure: fan 3 relative housing 2 walls and be provided with bypass exhaust duct 11 with airborne dust is installed, the two-port of bypass exhaust duct 11 is communicated with formation deslagging air channel respectively with fine fodder outlet 5 and slag-drip opening 12.
The bottom of described housing 2 is provided with sieve plate 6.
Be provided with change-speed gearing or gearbox between the axle of described airborne dust fan 3 and the power take-off 10.
Described fine fodder exports on the housing 2 of 5 positions and is connected with inserting groove 8, be provided with in the inserting groove 8 regulate air quantity insert-connecting plate 9.
It is concordant that described inserting groove 8 bottoms and fine fodder export 5 bottoms, and the upper end is higher than fine fodder and exports 5 tops.
In sum, the present invention is owing to the advantage of described structure is: high efficiency and kinetic energy loss are little, can regulate as required air quantity and speed change, can also reduce use cost.
