Abstract
The utility model relates to an anti-clogging winnower which comprises a shell; the side wall along the circumferential direction of the shell is provided with a rough rice outlet that can be communicated with a winnowing channel, and the shell is internally provided with a winnowing blade that is connected with a packing auger shaft in a coaxial way; a clapboard is arranged inside the shell along the radial direction, and the winnowing blade is positioned in the shell which is arranged at one side of the clapboard that faces to a packing auger; the shell arranged at the other side of the clapboard is internally provided with an air supply vane that is connected with the packing auger shaft in a coaxial way, and the side wall along the circumferential direction of the shell arranged at the other side of the clapboard is provided with an air outlet that is communicated with the winnowing channel; the air outlet and the rough rice outlet are arranged side by side, and an air inlet is opened on the end surface of the shell which is corresponding to the air supply vane. As the clapboard and the air supply vane are additionally arranged, the air inlet of the winnower can be set to be larger, so that the air supply is enough; at the same time, the wind power blown from the air supply vane into the winnowing channel is powerful, even if the rotating speed is not accelerated, light sundries such as husk, etc. can be blown out in time, so as to prevent the winnower from being blocked and generate pumping action to the corn mixture in the winnower, thereby improving the throwing performance of the winnower.
Description
Technical field
The utility model relates to a kind of cereal separation instrumentation, especially a kind of winnow that is used to carry cereal.
Background technology
Winnow is indispensable parts in the agricultural machinery such as grain harvester combine or thresing machine; mixtures such as the seed that the cereal of results forms after threshing, disconnected fringe, clever chaff and broken bar generally will be transported in the winnow through screw feeder; toss to the passage of winnowing by winnow again, so that light foreign material such as cereal kernel and clever chaff, broken bar are separated.The structure of common winnow comprises housing, grain inlet, outlet are arranged on the housing, and import is communicated with the screw feeder inner chamber, and channel connection exports and winnow, have in the housing and the coaxial blade of winnowing that is connected of screw conveyor shaft, on the housing end face of the blade of winnowing, have the air inlet of bore less than seed.The winnow of this structure in use, though can produce wind-force, wind-force is very limited; can not blow away being mixed in the lighter foreign material of proportion such as clever chaff in the cereal kernel and broken bar; so these light foreign material usually can be detained, stop up winnow, make the winnow can not normal operation.At present, reduce measure that winnow stops up and be the ability of tossing that the rotating speed that promptly improves screw conveyor shaft by the rotating speed that improves winnow promotes winnow, like this, though can receive certain effect, but also increased simultaneously cereal kernel when carrying by the ratio of the screw feeder blade and the blade injury of winnowing, reduce the quality of cereal kernel, also increased power consumption on the other hand.
The utility model content
The purpose of this utility model provides a kind of under the prerequisite that does not improve the winnow rotating speed, promotes the winnow of its conveying capacity to prevent to stop up.
For achieving the above object, the utility model adopts following technical scheme: the anti-clogging winnow, comprise housing, have on the circumferential side wall of housing can with the mouth of a valley that goes out of the channel connection of winnowing, have in the housing and the coaxial blade of winnowing that is connected of screw conveyor shaft, radially be provided with dividing plate in the housing, the blade of winnowing is positioned at the housing towards screw feeder one side of dividing plate; Be provided with in the housing of dividing plate opposite side and the coaxial wind feeding blades that is connected of screw conveyor shaft, on the circumferential side wall of this side body, have can with the air outlet of the described channel connection of winnowing, air outlet with go out the mouth of a valley and be arranged side by side, have air inlet on the housing end face of wind feeding blades relatively.
Described dividing plate is connected with screw conveyor shaft is coaxial, and winnow blade and wind feeding blades all are fixedly arranged on the dividing plate.
Described air outlet with go out mouth of a valley cross connection.
Wind feeding blades is arranged along the radial direction of screw conveyor shaft.
The inclined of the relative screw conveyor shaft of wind feeding blades arranges that wind feeding blades leans forward to the direction of rotation of screw conveyor shaft.
The inclined of the relative screw conveyor shaft of wind feeding blades arranges that wind feeding blades is to the direction of rotation hypsokinesis of screw conveyor shaft.
Compare with traditional winnow, the utility model has been set up dividing plate and wind feeding blades in housing, make the air inlet of winnow can offer greatlyyer, the air intake abundance, simultaneously the wind-force that blows in the passage of winnowing of wind feeding blades is powerful, like this under the prerequisite that does not improve the winnow rotating speed, not only light foreign material such as clever chaff and broken bar in time can be blown away, prevent to stop up winnow, can also produce certain swabbing action, thereby improve the ability of tossing of winnow the maslin in the winnow.When the utility model being disposed in the agricultural machinery such as grain harvester combine or thresing machine; can both prevent obstruction than the conveying task of finishing under the slow-speed of revolution cereal kernel and foreign material, guarantee the serviceability rate of cereal kernel again; and low in energy consumption, strong to cereal state adaptability.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the K of Fig. 1 is to view;
Fig. 3 is the winnow schematic diagram that wind feeding blades leans forward and is provided with;
Fig. 4 is the winnow schematic diagram that the wind feeding blades hypsokinesis is provided with.
The specific embodiment
Fig. 1, anti-clogging winnow shown in Figure 2, comprise housing, radially be provided with in the housing and the screw conveyor shaft 1 coaxial dividing plate that is connected 4, side towards screw feeder on the dividing plate is equipped with the blade 6 of winnowing, opposite side is equipped with wind feeding blades 3 on the dividing plate, wind feeding blades 3 is arranged along the radial direction of screw conveyor shaft 1, have bigger air inlet 2 on the housing end face of wind feeding blades 3 relatively, corresponding position of winnowing blade 6 has out the mouth of a valley on the housing perisporium, the position of corresponding wind feeding blades 3 has air outlet, air outlet with go out the mouth of a valley and be arranged side by side, and cross connection forms a big outlet, this outlet is communicated with the passage 7 of winnowing when winnow is installed and used, at the blade 6 of the winnowing seed of tossing in the passage of winnowing, in the time of mixtures such as grain husk chaff and broken bar, wind feeding blades 3 is blown in this passage, powerful wind-force can blow away light foreign material such as clever chaff and broken bar, prevents that winnow from blocking.In this structure, winnow blade and wind feeding blades also can be directly installed on the screw conveyor shaft.
Anti-clogging winnow shown in Figure 3, the difference of itself and Fig. 1, winnow shown in Figure 2 is, the inclined setting of wind feeding blades 6 relative screw conveyor shafts, wind feeding blades leans forward to the direction of rotation of screw conveyor shaft.
Anti-clogging winnow shown in Figure 4, the difference of itself and Fig. 1, winnow shown in Figure 2 is, the inclined setting of wind feeding blades 6 relative screw conveyor shafts, wind feeding blades 6 is to the direction of rotation hypsokinesis of screw conveyor shaft.
