Abstract
The invention provides sorting fan blades for a thresher. A plurality of blades are distributed uniformly around an axle hole in the middle of the side of a blade plate of thresher sorting fan blades produced through engineering plastic through one step. A side plane is arranged at the axle hole in the middle of the side of the blade plate, and accordingly, the semi-crescent axle hole is formed, the plurality of the blades are in balanced consistent curve structures, and a reinforcing supporting rib is arranged on each blade. By means of the sorting fan blades, the sorting fan blades can keep stable during high-speed operation, shaking caused by imbalance is prevented, and damage to equipment caused by shaking and loosening of the fan blades can be prevented.
Description
Technical field
The present invention relates to a kind of thresher component, fan blade cleaned by a kind of thresher specifically.
Background technology
Present thresher configure use clean fan blade, all produced by Metal Material Welding, this traditional mode of production can be different and thermal expansion shrinkage effect is inconsistent due to quality of welding spot during welding, dynamic equilibrium performance is caused to be affected, when thresher runs up, integral device can produce shake, under long playing state, the fatigue damage of component can be caused, the direct normal use affecting thresher, and then affect the service life of thresher, simultaneously, used fan blade axis hole is all circular, nut packing and rotating shaft is only relied on to fix, this structure also can operation due to fan blade time the anxious inertia stopped cause nut loosening, thus cause fan blade to damage.
Summary of the invention
The object of the present invention is to provide a kind of thresher to clean fan blade, overall operation dynamic equilibrium can be guaranteed, and produce loosening phenomenon under can not suddenly stopping the effect of inertia when high-speed cruising.
The present invention includes impeller and blade; the technical scheme adopted is: the thresher adopting engineering plastics one-shot forming to produce is cleaned the axis hole surrounding of fan blade in the middle of impeller side and is evenly distributed with several blade; axis hole in the middle of impeller side has a side plane, forms a meniscate axis hole of semicircle thus.Specifically add man-hour, size, the quality of several blade should be consistent, guarantee that dynamic equilibrium can reach best effects with this, and the axis hole arranged thus, after loading blade shaft, is fixed on blade shaft by side plane, can effectively avoid overall loosening with inertia.
In such scheme: several blade is balanced consistent warp architecture shape, each blade is provided with one and strengthens brace rod.Better can guarantee that High Rotation Speed can make blade more reliable and more stable thus.
Beneficial effect of the present invention is: due to the fan blade of cleaning of thresher be have employed above-mentioned such one setting; in addition adopt one-shot forming to produce to be integrated; when using after the integral installation formed; effectively can avoid the wild effect of High Rotation Speed; make the long-play of threshing function normal table; solve present thresher high-speed cruising and easily produce shake; the direct problem affecting thresher and normally run; there is handling ease, the low and favourable thresher processed safely of cost and improve the feature of operating efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is structural representation of the present invention.
Embodiment
Shown in Fig. 1: the thresher adopting engineering plastics one-shot forming to produce is cleaned axis hole 2 surrounding of fan blade in the middle of impeller 1 side and is evenly distributed with several blade 3; axis hole 2 in the middle of impeller 1 side has a side plane 4, forms a meniscate axis hole 2 of semicircle thus.Several blade 3 is balanced consistent warp architecture shape, and each blade 3 is provided with one and strengthens brace rod 5.
The blade 3 of the warp architecture that involved equilibrium is consistent, its equilibrium unanimously refers to that quality is consistent with size pattern, and warp architecture is the structure that a kind of microbend is rolled over, by accompanying drawing can be clear and definite statement described in warp architecture.
Claims (2)
1. fan blade cleaned by a thresher; comprise impeller (1) and blade (3); it is characterized in that: the thresher adopting engineering plastics one-shot forming to produce is cleaned axis hole (2) surrounding of fan blade in the middle of impeller (1) side and is evenly distributed with several blade (3); axis hole (2) in the middle of impeller (1) side has a side plane (4), forms a meniscate axis hole of semicircle (2) thus.
2. fan blade cleaned by thresher according to claim 1, it is characterized in that: several blade (3) is balanced consistent warp architecture shape, and each blade (3) is provided with one and strengthens brace rod (5).
