Abstract
The utility model discloses a double air channel oblique flow type cross flow fan for a combine harvester, comprising a fan scroll casing; a fan impeller is arranged in the fan scroll casing, a driving wheel is fixedly arranged at one end of the extending shaft of the fan impeller, and a cleaning air channel and a separating air channel are arranged on the fan scroll casing, and the separating air channel is an S-shaped air channel which leads a free jetting angle at the hole opening of the separating air channel to be remarkably improved, thus leading the air flow which is pre-cleaned to be blown out, and the probability that a few of wizened seeds which do Brownian movement collide with the top cover of a cleaning chamber is increased, therefore, the probability of interception and capturing is correspondingly increased, and the separating effect is increased.
Description
Technical field
The utility model relates to the cleaning and sorting system in a kind of grain combine, relates in particular to the fan in a kind of cleaning and sorting system.
Background technique
Be that the two air channels of the self-propelled axial flow grain combine diagonal flow type cross flow fan patented technology of representative exists following problem at present with Xinjiang-2:
(1) separation free jet angle, aperture, air channel (upper air duct) is too little, although adopt guide plate to improve efflux angle outside its aperture, because of jet inertia produces little effect, brings thus to comprise to blow out to be lost in interior series of negative effect.
(2) all with accordingly streamline is vertical with cleaning aperture, air channel (lower air duct) section to separate the air channel, produces thus with next problem:
1. orifice area is less than normal, not only produce the opening vortex loss, and air-flow useful effect covering of the fan is little and inhomogeneous.
2. the seed that falls from shuttle board pours in down a chimney easily into the air channel, particularly the moment of shutdown.
3. utilize the air quantity adjustable cap can not realize linearly adjust wind speed and air quantity.
The model utility content
Technical problem to be solved in the utility model provides a kind of performance and adapts to the two air channels of the combine diagonal flow type cross flow fan of cutting axial flow reinforcement threshing separation more.
For solving the problems of the technologies described above, the technical solution of the utility model is: the two air channels of combine diagonal flow type cross flow fan, comprise the fan spiral case, in the described fan spiral case blast fan is installed, the shaft extension of described blast fan goes out an end and is installed with drive wheel, described fan spiral case is provided with to be cleaned the air channel and separates the air channel, and described separation air channel is the serpentine air channel.
As a kind of improvement, the described air channel of cleaning is the vertical mouth with the described exhaust outlet that separates the air channel.
As further improvement, described drive wheel is the step change wheel that is fixedly mounted on the described fans wheel shaft.
As further improvement, described step change wheel comprises the price fixing on the axle that is fixed on described blast fan, with the Moving plate that described price fixing cooperates, is provided with the adjusting pad between described price fixing and the described Moving plate.
Owing to adopted technique scheme, the two air channels of combine diagonal flow type cross flow fan, comprise the fan spiral case, in the described fan spiral case blast fan is installed, the shaft extension of described blast fan goes out an end and is installed with drive wheel, described fan spiral case is provided with to be cleaned the air channel and separates the air channel, and described separation air channel is the serpentine air channel; The setting in serpentine air channel significantly improves the free jet angle of separating the aperture, air channel, thereby make a small amount of shrivelled seed and the increase of sorting chamber top cover collision energy dissipating probability that are blown away, do Brownian movement by pre-clear air-flow, thereby the also corresponding increase of probability of being intercepted and captured, increased the effect of separating.

Embodiment
As shown in Figure 1, the two air channels of combine diagonal flow type cross flow fan, comprise fan spiral case 1, in the described fan spiral case 1 blast fan 3 is installed, the end that the shaft extension of described blast fan 3 goes out described fan spiral case 1 is installed with drive wheel, and described drive wheel is a step change wheel 2, and described fan spiral case 1 is provided with cleans air channel 12, the described air channel 12 of cleaning is for exporting the tubaeform air channel of flaring from entering the mouth to, described clean air channel 12 clean the cleaning device of exhaust outlet 12c towards combine-harvester.
Tangential also being provided with of described fan spiral case 1 is positioned at described separation air channel 11 of cleaning 12 tops, air channel, and described separation air channel 11 is the serpentine air channel, and described separation air channel exhaust outlet is towards the segregating unit of combine-harvester.The free jet angle of separating the air channel exhaust outlet significantly improves, thereby makes a small amount of shrivelled seed and the increase of sorting chamber top cover collision energy dissipating probability that is blown away, does Brownian movement by pre-clear air-flow, thereby the also corresponding increase of probability of being intercepted and captured, and has increased the effect of separating.
As shown in Figure 2, the air port 11c that isolates in described separation air channel 11 is the vertical mouth.The described exhaust outlet 12c that cleans that cleans air channel 12 is the vertical mouth.Thereby significantly improved the useful effect covering of the fan of whole free jet, and made the more reasonable distribution in flow field, and the setting of vertical mouth has been avoided pouring in down a chimney into the air channel from the seed that shuttle board falls.
As shown in Figure 3, described step change wheel 2 comprises the price fixing 21 that is fixed on the described fan spiral case 1, with the Moving plate 22 that described price fixing 21 is connected, is provided with between described price fixing 21 and the described Moving plate 22 and regulates pad 23.Linear mutually based on rotating speed and wind speed, adopt step change to take turns 2 speed governing, " V " shape groove that promptly adopts increase and decrease to regulate pad 23 change step change wheels 2 is opened a grade physical dimension, realizes the step change purpose, and replaces former double flute surely than drive wheel with this.
