Embodiment 1

[0044] This embodiment provides a harvester fan, such as figure 1 and figure 2 As shown, it includes fan housing 3f, fan structure and fan drive.

[0045] The fan structure is installed in the cylindrical installation chamber of the fan housing 3f, and the two axial ends of the fan housing 3f are respectively provided with first air inlets 31f communicating with the outside world. The first air inlet 31f is a circular air inlet, concentric with the cross-section of the cylindrical installation cavity. An air outlet 33f is provided on the side wall of the fan housing 3f along its axial direction, and the width of the air outlet 33f is the same as that of the installation cavity. An air guide structure may be installed on the air outlet 33f, so as to guide the air to blow toward a set direction.

[0046] Such as figure 1 As shown, a second air inlet 32f is provided on the side wall of the fan housing 3f opposite to the air outlet 33f along the circumferential direction of t...

Abstract

The invention provides a harvester fan. The harvester fan comprises a fan shell, a fan structure and a fan driver. The fan structure is mounted in a cylindrical mounting cavity of the fan shell, and first air inlets communicating with the outside are formed at the two ends of the fan shell in the axial direction correspondingly. An air outlet is formed in the side wall of the fan shell in the axial direction of the fan shell, and the width of the air outlet is equal to that of the mounting cavity. A second air inlet is formed in the side wall, opposite to the air outlet, of the fan shell in the circumferential direction of the fan shell, and the second air inlet is located in the middle of the fan shell in the axial direction of the fan shell. The second air inlet is formed in the middle of the shell and matched with the first air inlets at the two ends of the fan shell, three air inlets evenly distributed in the fan shell are formed, enough air inlet amount is provided, and meanwhile air inlet is more uniform.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a harvester fan. Background technique [0002] Crawler combine harvester threshing system can be divided into crawler combine harvester threshing system can be divided into vertical axial flow threshing and cleaning system and horizontal axial flow threshing and cleaning system, these two forms of threshing and cleaning system are the most popular in the market The main structural form used above. [0003] The interior of the harvester is mainly divided into a threshing system, a screening system and a winnowing system from top to bottom. The function of the winnowing system is to continuously blow air towards the tail of the harvester, and the blowing air passes through the drop area of ​​crop seeds and the mesh screen in the screening system. On the surface, the debris such as broken grass and fluff, which are lighter than the crop grains, are blown out to the o...
