The induced-draft-type impurity discharging device is mounted on the middle-upper portion of the elevator of the corn harvester, an induced-draft-type impurity discharging fan is mounted on the upper portion of the elevator of the corn harvester, most of broken stalks and impure leaves are shredded in advance and discharged in a distributary manner, the induced-draft-type impurity discharging fan, and the impurity discharging pair roller on the rear portion of the elevator, a blower and the like form a combined impurity discharging mode, so that elevating and impurity discharging capacity of the corn harvester are improved, and working efficiency, operating performance and working reliability of the whole machine are improved.
Description
Technical field
The present invention relates to agricultural machinery equipment, especially a kind of elevator trash discharging apparatus of self-propelled corn harvester.
Background technology
The traditional board-like corn snapping unit of the general employing of self-propelled corn harvester ear harvesting bench, be characterized in that the seed damage is little, broken stipe is more, the fruit ear percentage of impurity is higher, therefore the trash discharging apparatus such as blower fan and pair roller are set to reduce the fruit ear percentage of impurity at the elevator top, but along with the raising of operating speed and the passing of harvest time, the assorted leaf of broken stipe and corn sharply increases, existing blower fan pair roller trash discharging apparatus can not to satisfy effectively impurities removal requirement, thereby operating efficiency and the fruit ear cleannes of machine have been reduced, particularly with the maize harvesting machine of debarker, the peeling effect reduces and accelerates the wearing and tearing of peeling rollers.
Summary of the invention
The object of the present invention is to provide a kind of maize harvesting machine air draught type trash discharging apparatus, by the disconnected stem stalk of the fruit ear in the elevator, assorted leaf are shunted processing in advance, the disconnected stem stalk of major part and assorted leaf are discharged in advance, thereby reduce the impurities removal amount of rear portion trash discharging apparatus, reach the effect that improves operating efficiency and operation quality.
Its technical scheme is: a kind of maize harvesting machine air draught type trash discharging apparatus, be installed in maize harvesting machine elevator middle and upper part, the front of impurities removal pair roller, with the elevator bolt-connection, the inlet scoop communicates with elevator, it is characterized in that: this device comprises lower case, fan shaft assembly, upper body, cover plate pin, cover plate, turns to the tooth case, and the described tooth case that turns to is connected with the power transmission of maize harvesting machine by driving member.
On the fan shaft assembly of described air draught type trash discharging apparatus the flail knife sheet is housed.
An air draught type trash discharging apparatus is installed above in the middle of existing self-propelled corn harvester elevator, this device is by fan, the chopping flail knife, housing, turn to the compositions such as tooth case, power can reach the gear-box wheel for inputting by driving member from the elevator upper shaft, after gear-box turns to, export and pass on the sprocket wheel that is installed on the fan shaft, drive the blower fan High Rotation Speed, produce negative pressure in import department, the leaf thereby the corn that relative mass is lighter is mixed, disconnected stem stalk picks up, after the chopping flail knife of High Rotation Speed is pulverized, dish out by blower fan, reach the disconnected stem stalk of major part and the assorted leaf of the corn purpose of shunting in advance.
The present invention is installed on maize harvesting machine elevator top air draught type impurities removal blower fan has been installed, in advance shunting after most disconnected stem stalk, the assorted leaf chopping is discharged, formed the combined type impurities removal with the impurities removal pair roller at elevator rear portion, hair-dryer etc., thereby promoted maize harvesting machine elevator impurities removal ability, improved operating efficiency, transaction capabilities and the functional reliability of complete machine.

Embodiment:
Installation site of the present invention structure diagram as shown in Figure 1.Apparatus of the present invention 2 are installed in the middle and upper part of elevator 1, the front of impurities removal pair roller 5, combined type impurities removal and elevator 1 bolt-connection have been formed with the impurities removal pair roller 5 at elevator rear portion, hair-dryer etc., the inlet scoop communicates with elevator, cover closure is used in the front and rear part that is connected with the air draught type trash discharging apparatus above the elevator, to strengthen the suction effect, power can reach the wheel for inputting that turns to tooth case 2.6 by driving member from elevator 1 upper shaft, the driving device operation.
Such as Fig. 2, shown in Figure 3, air draught type trash discharging apparatus of the present invention is by lower case 2.1, fan shaft assembly 2.2, upper body 2.3, cover plate pin 2.4, cover plate 2.5, turn to tooth case 2.6 to form.Upper-lower casing is that the spiral case opposite opened is formed by connecting with bolt, turn to tooth case 2.6 to be installed on the framework of upper body 2.3, fan shaft assembly 2.2 is installed between the blower fan upper-lower casing by bearing block 2.2.4, and cover plate 2.5 is hinged by cover plate pin 2.5 with upper body 2.3, to make things convenient for maintenance and inspection.Turn to tooth case 2.6 and fan shaft assembly 2.2 by chain drive power.
As shown in Figure 4, fan shaft assembly 2.2 is comprised of fan shaft seam 2.2.1, blade one 2.2.2, blade two 2.2.3, rolling bearing units 2.2.4, drive sprocket 2.2.5.Fan shaft seam 2.2.1 is formed by reinforcement disk 8.2.1.1, fan propeller 8.2.1.2, tool rest 2.2.1.4, axle 2.2.1.5 seam, blade one 2.2.2, blade two 2.2.3 are hinged on the tool rest 2.2.1.4 by bearing pin, and sprocket wheel 2.2.5 is connected on the axle by key.
In the housing of upper and lower part, there are respectively median septum 2.3.1,2.1.1 that it is divided into fan room and pulverizing chamber, cut concentric holes D on two dividing plates, UNICOM two Room.Blade one 2.2.2 tactical diameter should be greater than aperture D, and the tactical diameter of blade two 2.2.3 should not exceed the installation inclined-plane.
Lower case 2.1 interface width B and gradient β should be consistent with elevator 1 width and installation gradient.
During work, the corn ear that ear harvesting bench is taken, disconnected stem stalk, when the assorted leaf of corn upwards is transported to air draught type trash discharging apparatus installation site in elevator, the assorted leaf of the corn that quality is relatively light, the air-flow that disconnected stem stalk is produced by the blower fan of High Rotation Speed drives and picks up, after pulverizing, the chopping flail knife of High Rotation Speed dishes out by blower fan, the stem stalk that remaining fruit ear and part are long continues to move to the terminal and whereabouts of being dished out of elevator, in the dropping process, the stem stalk of not shunted, assorted leaf is under the effect that meets that rear portion impurities removal pair roller tractive and underlying blower fan blow, entering straw outlet discharges, fruit ear directly falls or falls into fruit-ear box through debarker after peeling and collect because heavier.The existing impurities removal of the present invention and maize harvesting machine mechanism forms the impurities removal of formation combined type, has strengthened maize harvesting machine elevator impurities removal ability, has improved operating efficiency, transaction capabilities and the functional reliability of complete machine.
