Described drive system (2) side and the ceding of Taiwan connect and are driven rotation by the ceding of Taiwan, and described drive system (2) opposite side passes described dust absorption fan (1) and dust shield (3) and drives fan blade (12) to rotate.
Described drive system (2) and the ceding of Taiwan realize connecting by following version: include the transmission regulating wheel (4) being arranged in the ceding of Taiwan, being arranged on the drive (5) that described drive system (2) side drives drive system (2) to operate, described drive (5) is driven by described transmission regulating wheel (4) and rotates.
Described drive system (2) drives fan blade (12) to rotate by power transmission shaft (21), and described power transmission shaft (21) passes described dust absorption fan (1) and dust shield (3).
Described power transmission shaft (21) both sides are fixed on dust shield (3) and outer housing (11) by bearing block respectively.
Described outer housing (11) is the worm frame form of spiral type.
Described fan blade (12) uses straight-vaned version, straight-vaned quantity to be 3 to 6.
The utility model has the advantages that: this utility model uses centrifugal fan, utilizes the power drive of harvester header drive system.The straw sucking blower fan can directly be sent outside machine by novel harvester ceding of Taiwan dust exhaust apparatus with air-out, solves the problem of straw blockage in axial-flow type dust absorption fan work process, improves working performance.
This utility model have employed the centrifugal fan dust absorption fan as harvester header dust exhaust apparatus, is cutting off, during effectively reducing or eliminate harvester operation, a large amount of airborne dusts produced above platform, and dust absorption fan operation smoothness will not occur straw blockage phenomenon.Working performance is high, it is ensured that the working environment of tractor driver.

Detailed description of the invention
This utility model includes dust absorption fan 1, drive system 2 and dust shield 3；
Described dust absorption fan 1 includes outer housing 11 and the fan blade 12 being arranged in outer housing 11；
Described dust shield 3 is arranged on the sidepiece of described dust absorption fan 1 and connects with dust absorption fan 1 formation；
Described drive system 2 side and the ceding of Taiwan connect and are driven rotation by the ceding of Taiwan, and described drive system 2 opposite side passes described dust absorption fan 1 and dust shield 3 and drives fan blade 12 to rotate.
Described drive system 2 and the ceding of Taiwan realize connecting by following version: include the transmission regulating wheel 4 being arranged in the ceding of Taiwan, being arranged on described drive system 2 side and drive the drive 5 of drive system 2 operating, described drive 5 is driven rotation by described transmission regulating wheel 4.
Described drive system 2 drives fan blade 12 to rotate by power transmission shaft 21, and described power transmission shaft 21 is through described dust absorption fan 1 and dust shield 3.
Described power transmission shaft 21 both sides are fixed on dust shield 3 and outer housing 11 by bearing block respectively.
Described outer housing 11 is the worm frame form of spiral type.
Described fan blade 12 uses straight-vaned version, straight-vaned quantity to be 3 to 6.
Below this utility model is made further instructions:
The power transmission shaft 21 of this utility model drive system 2 in the middle of the outer housing 11 of dust shield 3 and dust absorption fan 1 through and be separately fixed at the side plate of dust shield 3 and the panel of outer housing 11 at the two ends bearing block of power transmission shaft 21.The fan blade 12 being positioned at dust absorption fan 1 outer housing 11 is arranged on the power transmission shaft 21 of drive system 2 and can rotate with the power transmission shaft 21 of drive system 2.
The outer housing 11 of dust absorption fan 1 of the present utility model uses the spiral case of spiral type, and the fan blade 12 of dust absorption fan 1 uses prismatic blade, and for avoiding fan blade 12 to block, straight-vaned quantity uses 3 to 6.
