Currently existing seed cotton cleaning machines can be divided into two types according to the flow condition of cotton: a horizontal seed cotton cleaner with cotton flow flowing horizontally and an inclined seed cotton cleaner with cotton flow flowing obliquely,
chinese patent CN20489154U shows an inclined seed cotton cleaning machine, which is known from its structure to be provided with a plurality of spike rollers and a grid bar below each spike roller at a distance, and the gap between the spacers in the grid bar is an important factor affecting seed cotton cleaning efficiency. The basic structure of the grid is not explicitly shown in chinese patent CN204849154U, and the grid may be considered as an assembly formed by assembling a plurality of parallel grids through end plates, and is similar to the grid structure as a whole, and is called grid. The spacing between adjacent bars is approximately the same, and impurities generated by cleaning fall through the gaps between the bars. The non-standard names of the grid bars are also grid bars, grid bars and the like.
It should be noted that the grating gate not only separates seed cotton from separated impurities, but also has larger relative motion with the rotating spike roller, and the seed cotton wound by the spike roller can rub and strike the grating gate in the advancing process, so that the impurities are separated from the seed cotton. The intensity of friction and striking is related to the shape and the spacing of the grids on the grid bars, so that different grid bar spacing is adapted for seed cotton with different quality, and the technical development direction of the vehicle matching with flowers is met. However, the grid bars on the grid bars of the seed cotton cleaning machine in the current market are generally welded with the end plates, namely, the grid bars are relatively fixed, and the mutual distance adjustment cannot be performed, so that the vehicle distribution due to flowers cannot be realized.
The Chinese patent document CN204849132U discloses a grid screen used for a seed cotton cleaning machine, which provides a conventional structure of a grid, and is provided with two end plates and a plurality of flat steels, namely grid bars, wherein the two end plates are arranged in parallel and used for determining the width of the grid, the flat steels are sequentially arranged and fixedly connected on the upper edges of the end plates, and a plurality of rib plates are further arranged between the two end plates and are interwoven with the flat steels into a net shape for improving the overall rigidity. The flat steel is used for replacing round steel, so that the cleaning effect is improved, however, the distance between the flat steel cannot be adjusted, in other words, the cleaning effect is relatively fixed, and the vehicle can not be matched due to flowers.
