Abstract
The utility model discloses a through-flow blower for a maize machine, which includes a volute casing and an impeller rotationally assembled in the volute casing, wherein an air inlet and an air outlet both extending in the spiral direction of the volute casing are formed in the side wall of the volute casing respectively; a volute tongue is communicated with the air outlet of the volute casing; a wind volume adjusting plate used for controlling the size of the air inlet and extending in the spiral direction of the volute casing is arranged at the air inlet of the volute casing in a sliding manner; and a wind pressure adjusting plate used for controlling the size of the air outlet and extending in the spiral direction of the volute casing is arranged at the air outlet of the volute casing in a sliding manner. The size of the air outlet can be controlled through the wind pressure adjusting plate to adjust the intensity of airflow entering the volute tongue, and finally adjust the intensity of airflow exhausting from the volute tongue, so that the normal operation of the maize machine cannot be influenced by over-big or over-small airflow.
Description
Technical field
The utility model relates to the cleaning fan device of corn machine, is specifically related to a kind of diagonal flow type cross flow fan.
Background technique
Existing corn machine cleaning fan device adopts straight leaf centrifugal fan of hypsokinesis and diagonal flow type cross flow fan more.The specific of centrifugal blower is: pressure is bigger, and width is bigger, and receives the restriction of corn machine complete machine structure; It is too big that blower fan can not be done, and for improving its ability to work, has to improve its rotating speed; Need thicker axle and bigger bearing and having relatively high expectations after improving rotating speed to balance; The fluctuation of static pressure causes the variation of operating mode easily in addition, and this just makes the vibrations of centrifugal blower, noise increase, and influences the reliability of machine and tractor driver's operating environment.
And cross flow fan has solved the big and big problem of noise of centrifugal blower volume; Cross flow fan comprises that spiral case and rotation are assemblied in the impeller in the spiral case; Spiral case has intake grill and the exhaust outlet that extends along its Hand of spiral; The connection of exhaust outlet place is provided with tubular snail tongue, and impeller is by constituting along the spaced apart arc shaped blade of its circumferencial direction.During the impeller rotation, air-flow gets in the impeller from the slit of intake grill between blade of spiral case, gets into the snail tongue by the slit between the blade through the exhaust outlet of spiral case again, is finally discharged by the exhaust port of snail tongue.The corn machine is when work, and snail tongue exhaust port relies on the rotation of impeller towards iblet, and air-flow is blowed to iblet and removes the impurity in the iblet.But the air-flow that cross flow fan is discharged can't be regulated, if air-flow is excessive, easily impurity is removed together with iblet, causes waste; If air-flow is too small, the removing poor effect of impurity.
The model utility content
The purpose of the utility model provides a kind of can the adjusting and discharges the big or small cross flow fan of air-flow.
The utility model adopts following technological scheme: a kind of cross flow fan that is used for the corn machine; Comprise that spiral case and rotation are assemblied in the impeller in the spiral case; Offer the intake grill and the exhaust outlet that extend along the snail shell coiling direction on the sidewall of said spiral case respectively; The exhaust outlet place connection of spiral case is provided with the snail tongue; Sliding and be provided with the air-flow plate that is used to control the intake grill size that extends along the snail shell coiling direction in the intake grill place of said spiral case, slides and be provided with the blast regulator plate that is used to control the exhaust outlet size that extends along the snail shell coiling direction in the exhaust outlet place of said spiral case.
Said blast regulator plate and air-flow plate are the curved plate structure of coincideing and cooperating with the sidewall of said spiral case.
The length of said air-flow plate is greater than intake grill length, and the length that said blast adjusting is not taken is greater than exhaust outlet length.
Adopt the cross flow fan of said structure; Sliding respectively and are provided with air-flow plate and blast regulator plate in the spiral case intake grill place of cross flow fan and exhaust outlet place, through the size of air-flow plate control intake grill, thereby regulates the air-flow size that gets in the spiral case; Size through blast regulator plate control exhaust outlet; Thereby regulate the air-flow size that gets into the snail tongue, the final air-flow size of being discharged by the snail tongue of regulating has prevented the excessive or too small proper functioning that influences the corn machine of air-flow.

Fig. 2 is the left view of Fig. 1.
Embodiment
A kind of embodiment who is used for the cross flow fan of corn machine of the utility model: like Fig. 1, shown in Figure 2; The spiral case 1 of cross flow fan is a tubular structure; Be rotatably equipped with impeller 3 in the spiral case 1, the blade formation that impeller 3 is served as reasons and is provided with at interval along its circumferencial direction offers the intake grill that extends along spiral case 1 Hand of spiral on the lower end sidewall of spiral case 1; Offer the exhaust outlet that extends along spiral case 1 Hand of spiral on the upper end sidewall of spiral case 1; Exhaust outlet place sealing is provided with the tubular snail tongue 4 that is communicated with spiral case 1, and the end of snail tongue 4 is an exhaust port, and above content is existing technology or can realizes through existing technology.Slide respectively and are provided with air-flow plate 5 and blast regulator plate 2 in the intake grill place of spiral case 1 and exhaust outlet place, air-flow plate 5 is the curved plate structure of coincideing and cooperating with spiral case 1 outer circumferential face with blast regulator plate 2.Move the size of air-flow plate 5 control intake grills along the circumferencial direction of spiral case 1, thereby regulate the air-flow size that gets into by intake grill; Move the size of blast regulator plate 2 control exhaust outlets along spiral case 1 circumferencial direction, thereby regulate the air-flow size that gets into snail tongue 4, can pass through in order to guarantee blast regulator plate 2, said spiral case 1 offers with snail tongue 4 connecting parts and is used for the gap that blast regulator plate 2 passes through.For the size that guarantees intake grill and exhaust outlet is consistent in spiral case 1 Hand of spiral all the time, the length of said air-flow plate 5 is greater than the length of intake grill, and the length of blast regulator plate 2 is greater than the length of exhaust outlet.
In the foregoing description, said air-flow plate 5 is the curved plate structure with blast regulator plate 2, in other embodiments, also can be platy structure.
The foregoing description is when in running order, and air-flow is got in the impeller 3, through the rotation of impeller 3 by the slit of intake grill between blade of spiral case 1; Get into snail tongue 4 by the slit between the blade through exhaust outlet again, finally the exhaust port by snail tongue 4 blows to iblet, when air quantity is excessive; Move air-flow plate 5 and blast regulator plate 2, intake grill and exhaust outlet are diminished, when air quantity is too small; Move air-flow plate 5 and blast regulator plate 2, make intake grill and exhaust outlet become big.
