Detailed Description
The principles and features of the present invention are described below in conjunction with the drawings and the embodiments, which are set forth for the purpose of illustration only and are not intended to limit the scope of the invention.
As shown in fig. 1 and 2, this embodiment provides a cleaning auxiliary mechanism, include an installation pole 11 and many edges that set up along the left and right direction level installation pole 11 length direction interval install on it and be the distribution tooth 12 of bar, many the equal vertical setting of distribution tooth 12, every the upper end of distribution tooth 12 respectively with installation pole 11 is connected, every the lower extreme of distribution tooth 12 extends to the rear side below respectively, and many the lower extreme level of distribution tooth 12 is unanimous, and its simple structure can make grain on the sifter distribute more evenly on the sifter through the distribution tooth, is favorable to improving its screening effect so.
In the technical scheme, the distribution teeth 12 are divided into two groups, each group is provided with a plurality of distribution teeth, the distribution teeth 12 are respectively distributed at two ends of the mounting rod 11, and the lower end of one distribution tooth, which is close to the middle part of the mounting rod 11, of two adjacent distribution teeth 12 in the same group is positioned behind the lower end of the other distribution tooth 12, so that the grains on the screen surface can be distributed more uniformly, namely the grains on the screen surface are firstly distributed to two sides by the distribution teeth at the middle part and then distributed by the distribution teeth close to the two sides step by step.
In the above technical scheme the distribution teeth 12 are in the shape of a bent strip, and every the distribution teeth 12 are respectively provided with a vertical section located above and a bending section located below the vertical section and bent towards the rear lower part, so that the size of the cleaning auxiliary mechanism can be reduced.
In the above technical scheme, the bending section of the distribution teeth 12 is bent towards the rear lower part to be close to the middle part of the mounting rod 11, so that the area of spreading materials of each distribution tooth is larger, and the screening effect is better.
