Abstract
The utility model relates to a threshing roller of a rice thresher, which is composed of channel steel racks, a main shaft and two circular rack installing frames sheathed on the main shaft, wherein the channel steel racks has odd teeth and even teeth; teeth on the racks form a non-symmetrical reverse U shape, namely that one side of the U-shaped teeth forms a crescent machete shape, and the other end is relatively sharp; the odd teeth or even teeth are uniformly, evenly and regularly welded on a piece of channel steel along the direction of a surface in the shape of a crescent machete; the whole roller using ten to twelve channel steel racks in alternative arrangement according to the odd teeth and the even teeth are installed on installation holes of the two circular rack installing frames. The utility model is mainly used on an automatic cereal and straw separating type power paddy rice thresher. Compared with the prior art, the ear and cereal straw crashing rate in mature grain is reduced by 70 %, and grain yield efficiency is improved by 20 %. The utility model can be also suitable for batch mechanization production.
Description
Technical field
The utility model relates to the sheller unit on the rice thresher, particularly a kind of threshing cylinder of rice thresher.
Background technology
Existing rice thresher threshing cylinder is made up of polylith plank tooth bar, main shaft and two rack circle mounting brackets being enclosed within on the main shaft." U " shape is manual squeezes in the plank because the tooth on the plank tooth bar is curved down by iron wire, when using this threshing cylinder, the tooth on the plank tooth bar impacts spike of rice sticking effect of drawing in the process, will put in order the strain spike of rice easily and pull out, cause broken spike of rice millet straw too much, but also paddy efficient is produced in influence.Every plank tooth bar all will be squeezed into " U " shape iron wire by hand in addition, and homogeneity of product is poor, can not adapt to industrialization.
Summary of the invention
The purpose of this utility model is to provide a kind of through threshing, produces paddy efficient height, can be fit to the rice thresher threshing cylinder that mechanization is in batches produced.
To achieve these goals, the threshing cylinder of a kind of rice thresher that the utility model proposes is made up of channel-section steel tooth bar, main shaft and two rack circle mounting brackets being enclosed within on the main shaft.Described channel-section steel tooth bar has two kinds in odd number tooth and even number tooth, tooth on its tooth bar is asymmetric " U " shape, that is: " U " shape tooth one side wherein is crescent moon tulwar shape, another side is relatively for very precipitous, and this tooth is even, neat with odd number or even number, crescent moon tulwar shape face direction as one man is welded on the channel-section steel; Whole cylinder is alternately arranged by odd number tooth and even number tooth with ten to 12 channel-section steel tooth bars and is installed on the installing hole of two rack circle mounting brackets.
Because the utility model improves the profile of tooth of tooth bar, soon " U " shape tooth one side is wherein made and is crescent moon tulwar shape, another side is relatively for very precipitous, when using this threshing cylinder, this tooth impacts spike of rice has the slip of cutting as cutter to hit the effect of cutting in the process, can like a cork the paddy in the spike of rice be hit and cut out, can not pull out putting in order the strain spike of rice.Reduced the broken spike of rice millet straw of Cheng Guzhong.Can reduce the broken spike of rice millet straw 70% of Cheng Guzhong in actual the use compared to existing technology, produce paddy efficient and also improved 20%.Therefore the utility model through threshing, produce paddy efficient height.Asymmetric " U " shape tooth of the present utility model in addition is welded on the channel-section steel, does not need non-operation by hand, so can be fit to mechanization production in batches.
Description of drawings
Fig. 1 is a profile schematic diagram of the present utility model;
Fig. 2 is an application state schematic diagram of the present utility model;
In above-mentioned figure: 1 threshing cylinder; 11 channel-section steel tooth bars; 12 main shafts; 13 rack circle mounting brackets; Tooth on 14 tooth bars; 15 installing holes; 2 automatic millet straw separate type power rice threshers.
Specific embodiment
The utility model is described in more detail with concrete embodiment below in conjunction with accompanying drawing:
Present embodiment is a kind of threshing cylinder of automatic millet straw separate type power rice thresher, and this threshing cylinder is made up of channel-section steel tooth bar 11, main shaft 12 and two rack circle mounting brackets 13 being enclosed within on the main shaft.Described channel-section steel tooth bar 11 has described channel-section steel tooth bar (11) that two kinds of seven teeth and octadentates are arranged.Tooth 14 on its tooth bar is asymmetric " U " shape of falling, that is: " U " one side the shape tooth wherein be crescent moon tulwar shape, another side is relatively for very precipitous, this tooth with seven or eight evenly, neatly, crescent moon tulwar shape face direction as one man is welded on the channel-section steel; Whole cylinder is alternately arranged by odd number tooth and even number tooth with ten to 12 channel-section steel tooth bars 11 and is installed on the installing hole 15 of two rack circle mounting brackets 13.
Accompanying drawing 2 is that the threshing cylinder 1 with present embodiment is installed in a kind of automatic millet straw separate type power rice thresher 2 application state schematic diagrames.
