grain thresher machine for sorghum grain thresher machine development
in old times one of the simplest grain thresher equipment for threshing sorghum,wheat,millet,rice, is to pick up the sheaf of the grains sorghum and strike the panicles against a hard surface.Another frequently-used method of threshing sorghum is to trample it underfoot.Threshing sorghum, as well as wheat,rice,soybean,peanut,or groundnuts, can be done by striking sheaves spread out on a threshing-floor with a flail or a stick.The threshing-floors on which the sheaves are spread must have a hard, clean surface.By using one of these methods of hand-threshing, a worker can obtain 15 to 40 kg of product per hour.manual grain thresher machine for sorghum, which are relatively common and sometimes made by local artisans, permit easier and faster shelling of ears of grains like sorghum,maize,wheat,rice. These come in several models, some of them equipped to take a motor; they are generally driven by a handle or a pedal.Use of manual sorghum thresher machine generally requires only one worker.With yields of from 14 to 100 kg/in, they are well-adapted to the needs of small-scale production
Threshing with animals or vehicles
as time development,animals driven threshing are available and there are large quantities of sorghum threshing can be done by driving the animals over a layer of sheaves about 30 cm thick.This kind of operation, which is also called “treading out”, can equally well be accomplished with vehicles.This method of threshing sorghum is adopted in some Asian countries, using a tractor for power instead of draught animals.Paddy is obtained by running the tractor twice over sheaves of rice that are spread in layers on a circular threshing-floor 15-18 m in diameter.
Threshing or shelling with motorized equipment
In describing operations of threshing or shelling with motorized grain thresher equipment for sorghum,rice,wheat, the principal reference will be to motorized threshing machines.Although they are gradually being replaced by combine-harvesters, these machines still have an important place in the post-harvest production process, especially for their convertibility.By the simple replacement of a few accessories and the appropriate changes in settings, these machines can treat different kinds of grain (e.g. rice, maize, sorghum, beans, sunflowers, wheat, soybeans, etc.).which is quipped with a rotating threshing-drum and a stationary counter-thresher, these machines often have devices to shake out the straw and to clean and bag the Brain.Whether self-propelled or tractor-drawn, these threshers are often mounted on rubbertyred wheels for easy movement to the field.
On many small holder farmers, mechanical threshers can replace manual threshing by hand beating, a practice that often results in grain spillage, grain breakage, and incomplete separation of the grain from the chaff. Manual threshing is also a very labor and time intensive process that results in high human energy expenditure and a high rate of drudgery in the agricultural system. The introduction of low-cost, locally-produced mechanized threshing systems in smallholder agriculture can significantly reduce post-harvest loss in staple food grains.
we are as multifunction grain thresher manufacturers to develop a larger-scale multi grain thresher for sorghum with zero machine loss that can shell maize and thresh soybean, rice, beans, sorghum and other crops. The motorized grain thresher for sorghum is 40 times faster than manual beating when harvesting soybean, produces almost no dust, has near zero machine loss, does not split seeds, winnows out chaff, and requires only two people to feed and operate it efficiently. Commercially available multi-crop threshers that were also tested had from 5-50% machine loss of grain, required more people to operate, and produced large amounts of dust. The multifunction grains thresher for sorghum which has different threshing concaves for different crops, sells in Ghana for approximately $2,000 U.S. and is designed for middle-sized farmers or for-hire service providers who can also provide threshing services to groups of smallholder farmers.
