Foot-pedaling paddy rice threshing machine

Abstract

A foot-pedaling paddy rice threshing machine comprises a rack, a material accommodating drum and two sets of stirring mechanisms. The front end of a first connection rod of each stirring mechanism is connected to the rack via a first rotating pair; a pedal is fixed on the back end of the first connection rod; one end of a second connection rod is connected to the first connection rod via a second rotating pair; the other end of the second connection rod is connected to a driving belt wheel via a third rotating pair; a rotating shaft of each driving belt wheel is fixed on the upper end of a first supporting rod via a bearing and a bearing seat; the lower end of the first supporting rod is fixed on the rack; two ends of a wheel shaft of each stirring propeller wheel are fixed on the upper end of a second supporting rod and the center of the side surface of the material accommodating drum via a bearing and a bearing seat; the second supporting rod is disposed in the material accommodating drum; a driven belt wheel is fixed on the end head of the wheel shaft of each stirring propeller wheel outside the material accommodating drum; and a belt is tensioned on each driving belt wheel and each driven belt wheel. Speed difference between stirring propeller wheels is utilized, shearing force is added on the basis of paddy rice beating force, so grain can be easily separated from rice spikes.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a foot-operated paddy thresher. Background technique [0002] Although mechanized rice harvesting has begun to be popularized in many areas, the traditional foot-operated rice thresher is still practical in the western mountainous areas with complex terrain and potholes. , there are many stones, and large harvesters cannot adapt to such mountainous terrain. On the other hand, in hilly areas, rice is planted in terraced fields, and small mechanical threshing machines need to use batteries or gasoline. In the terraced fields, and the terraced fields are built along the contour of the hills, they need to be moved frequently and require a lot of labor. Generally, the mountainous areas are economically underdeveloped, and young people go out to work. Most of the rural laborers are old people. For Older people with low education levels find it difficult to operate small mechanica...

[0002] Although mechanized rice harvesting has begun to be popularized in many areas, the traditional foot-operated rice thresher is still practical in the western mountainous areas with complex terrain and potholes. , there are many stones, and large harvesters cannot adapt to such mountainous terrain. On the other hand, in hilly areas, rice is planted in terraced fields, and small mechanical threshing machines need to use batteries or gasoline. In the terraced fields, and the terraced fields are built along the contour of the hills, they need to be moved frequently and require a lot of labor. Generally, the mountainous areas are economically underdeveloped, and young people go out to work. Most of the rural laborers are old people. For Elderly people with low educational level find it difficult to operate small mechanical harvesting equipment, and prefer to continue to use the traditional foot-operated rice thresher that has been used for a lifetime
