Abstract
The utility model discloses a cleaning device of a combined harvester. The cleaning device of the combined harvester comprises a stand, a vibrating screen, a blower and an induced draft fan. The blower is arranged at a feed opening of the cleaning device, and the induced draft fan is arranged above the discharge end of the vibrating screen. The induced draft fan comprises a rotating shaft, two rotary plates and a plurality of strip-shaped fan blades. Two ends of each fan blade are fixed on the two rotary plates, and the fan blades are fixed on the rotary plates along the radial direction. The rotating shaft passes through the center of the rotary plates to firmly connect with the rotary plates. Two ends of the rotating shaft are fixed on the stand through bearings, and one end of the rotating shaft is connected with a power device through a transmission mechanism. The side of the induced draft fan towards a discharge hole of the cleaning device is provided with a separating plate fixed on the stand. The cleaning device of the combined harvester is capable of sucking and discharging lighter impurities on the vibrating sieve, so that the impurities are avoided from accumulating on the sieve surface, the vibrating sieve cleaning area is reduced, the problem of unclean seeds due to too much chaffs after the seed cleaning is avoided, and the cleaning effect is greatly improved.
Description
Technical field
The utility model belongs to agricultural mechanical field, relates to the cleaning plant of a kind of combined harvester, particularly a kind of combined harvester.
Background technology
For meeting the demand in present market, combined harvester constantly develops to the large feed quantity of high-power aspect.And the cleaning plant of combined harvester is a key device, because feed quantity increases, and the hair-dryer wind-force deficiency of a centrifugation, vibratory sieve discharge end stacking material and stop up the problem such as sieve aperture particularly on ubiquity vibratory sieve, and then cause and clean area and reduce, in cleaning load deficiency, tanker the too much seed of clever chaff unclean etc. technical problem, greatly affected result of use.
Utility model content
The utility model provides a kind of cleaning plant of combined harvester, and object is the unclean problem of the too much seed of clever chaff after solution cleaning load deficiency and seed cleaning.
To achieve these goals, the technical scheme that the utility model is taked is:
The cleaning plant of described combined harvester, comprises frame, vibratory sieve, and described vibratory sieve is provided with hair-dryer, and the discharge end top of described vibratory sieve is provided with attraction blower fan; Described attraction blower fan is provided with towards described cleaning plant discharging opening one side the separating plate being fixed in described frame, and described separating plate is obliquely installed, and one side of close described attraction blower fan is higher than another side.
Adopt this scheme can increase the wind-force on vibratory sieve, by the particularly outside sucking-off of the material of discharge end on vibratory sieve.Prevent that solid accumulation is on compass screen surface, reduce the area of cleaning of vibratory sieve, improve the effect of cleaning.Lighter assorted remainingly separate from the top of separating plate, seed falls into tanker from the below of separating plate, avoids the unclean problem of the too much seed of clever chaff after seed cleaning.
Brief description of the drawings
Fig. 1 is the structural representation of the cleaning plant of a kind of combined harvester of the utility model.
Being labeled as in figure:
1, frame; 2, rotating disk; 3, rotating shaft; 4, flabellum; 5, separating plate; 6, vibratory sieve.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail, to help those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the present utility model, technical scheme.
As shown in Figure 1, the utility model provides a kind of cleaning plant of combined harvester, comprises frame 1, vibratory sieve 6, hair-dryer and attraction blower fan.Hair-dryer is located at cleaning plant spout place, and the material on vibratory sieve 6 is blown and cleaned.Because inventory is more, less at the wind-force at cleaning plant discharging opening place, therefore above the discharge end of vibratory sieve 6, an attraction blower fan is set, to increase wind-force, prevent solid accumulation, improve and clean effect.
Attract blower fan to comprise the flabellum 4 of rotating shaft 3, two rotating disks 2 and some strips.The two ends of flabellum 4 are separately fixed on two rotating disks 2, and flabellum 4 is radially fixing on rotating disk 2.Rotating shaft 3 is fixedly connected with rotating disk 2 through the center of rotating disk 2.Rotating shaft 3 is laterally arranged in frame 1 by bearing, and one end of rotating shaft 3 is connected on power set by transmission mechanism.Above discharging opening, reduce air pressure by blower fan, by material sucking-off.The two ends of flabellum 4 are stressed, can be because of the excessive deformed damaged of local pressure.The length of flabellum 4 is not less than the width of vibratory sieve 6, thereby makes the material of discharge end all be subject to attracting the suction affects of blower fan.
The rotation direction of described attraction blower fan and the direction of rotation of described hair-dryer.Because hair-dryer is to make the wind blowing out produce impulsive force to material, wind direction downwards.Be upwards and attract the suction of blower fan, its rotation direction should be contrary with hair-dryer.
Attracting blower fan to be provided with the separating plate 5 being fixed in frame 1 towards cleaning plant discharging opening one side.Separating plate 5 is obliquely installed, and near attracting, one side of blower fan is higher, and away from attracting, one side of blower fan is lower.Lighter assorted remainingly separate from the top of separating plate 5, seed falls into tanker from the below of separating plate 5, avoids the unclean problem of the too much seed of clever chaff after seed cleaning.
In the time that cleaning plant is worked, vibratory sieve 6 constantly vibrates, and hair-dryer and attraction blower fan are worked simultaneously.Under the wind-force effect that material produces at blower fan, constantly move to discharging opening.Particularly, at the discharge end of vibratory sieve 6, attract the suction of blower fan to become the main power that attracts material movement.Material is attracted blower fan and picks up, lighter assorted remainingly separate from the top of separating plate 5, and seed falls into tanker from the below of separating plate 5, effectively completes cleaning of seed, has solved the unclean problem of seed.
