Abstract
The utility model relates to a rice thresher which can separate grains from straws. The utility model is characterized in that the existing rice thresher is provided with a vibratory screen mechanism and a waterwheel type chain wheel grain conveying mechanism with a spiral push rod, and a diesel engine serves as a power source. In operation, rice ears are fed onto a threshing drum; grains drop in a rice collecting bucket and are transferred to a pannier; a portion of straws is knocked down to a vibratory screen and removed from the machine. The machine has simple structure, peculiar design, easy operation and wide application range. In threshing course, automatic separation of grains from straws is achieved; moreover, grains are automatically transferred to the pannier without the need of manually removing straws or discharging grains. Harmful dust inhaled by operators can be decreased. The machine reduces labor intensity, enhances work efficiency, and ameliorates working environment, which is an ideal threshing machine for agricultural work.
Description
Technical field

Background technology
Existing rice thresher generally is divided into two big classes: promptly artificial rice thresher and Electric rice thresher.Artificial rice thresher is when operation, spike of rice threshing under the effect of threshing cylinder, its grain is fallen into the rice thresher bottom half, millet straw is mingled with together, must remove straw by artificial screening, with dustpan the millet large bamboo or wicker basket of packing into is transported then, owing to can not carry out millet straw and separate automatically, and must manually remove straw and people's frock basket, and so labour intensity is big, inefficiency.And Electric rice thresher is to need power supply, in the mountain area of keeping away partially or when not having power supply, just is not suitable for farm work.Though the Electric rice thresher that has can accomplish that millet straw separates, complex structure, drive disk assembly is too many, and the cost height, is not suitable for farmland operation.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, the power rice thresher that provide a kind of simple in structure, easy to manufacture, cost is low separates automatically with millet straw.
The technical solution of the utility model is to set up straw vibratory sieve mechanism and Waterwheel-type sprocket wheel grain conveying mechanism on existing artificial rice thresher, adopt diesel engine as power source, at frame rear end one rice-collecting bucket is set, one collection paddy groove is arranged in the rice-collecting bucket, by the grain auger cardan shaft in the collection paddy groove grain is entered in the Waterwheel-type sprocket wheel grain transport tube, chain by the band blade is transferred to grain in the large bamboo or wicker basket then, during operation, start diesel engine and drive the threshing cylinder rotation, spike of rice is fed on the threshing cylinder, its grain and part straw stalk leaf are shot down, drop on vibrating screen, its grain falls into and enters collection paddy groove in the rice-collecting bucket, by the rotation cardan shaft grain is pushed in the transport tube more thereupon, by the Waterwheel-type chain-wheel mechanism grain is transferred in the large bamboo or wicker basket at last, its straw is eliminated on vibrating screen and sends outside the body.The concrete scheme of this rice thresher is as follows: it comprises frame, drive on threshing cylinder, cover cap, belt, diesel engine, mesh screen, the drum shaft, driving belt and lower driving wheel is characterized in that: diesel engine and the both sides on the power rice thresher that the power rice thresher that millet straw separates is provided with as power source are respectively equipped with straw vibratory sieve mechanism and Waterwheel-type sprocket wheel grain conveying mechanism; Diesel engine is arranged on the frame, is connected with threshing cylinder by belt; Straw vibratory sieve mechanism comprises mesh screen, pushes away the sieve bar and by turning the connecting lever that axle and connecting rod and adjustable plate constitute, its mesh screen front end is provided with pulley at the bottom of the sieve that moves back and forth on the frame, mesh screen places on the frame and to become 8 °～15 ° angle with horizontal plane, pushing away the sieve bar is arranged on the frame under the threshing workbench and with mesh screen and is connected, the axle that turns of connecting lever upper end is arranged on the drive of drum shaft, and the adjustable plate of connecting lever lower end sieves bar one end and is connected with pushing away;
Described Waterwheel-type sprocket wheel grain conveying mechanism is to comprise grain auger cardan shaft, Waterwheel-type sprocket wheel grain transport tube and grian-feeding barrel, its Waterwheel-type sprocket wheel grain transport tube is made of cylindrical shell, upper and lower gear and the chain with uniform blade that is looped around on the lower gear, it cogs and is fixed on the frame, and lower gear is sleeved on the grain auger cardan shaft;
The mesh screen bottom has a rice-collecting bucket, rice-collecting bucket bottom to be provided with a collection paddy groove, collection paddy groove communicates with the import of Waterwheel-type sprocket wheel transport tube, in the collection paddy groove grain auger cardan shaft is set, cardan shaft one end is connected with lower driving wheel, and the lower gear in the other end and the Waterwheel-type sprocket wheel grain transport tube is connected.
In sum, the utility model is simple in structure, novel in design unique, easy and simple to handle, accommodation is extensive, vibratory sieve mechanism and Waterwheel-type sprocket wheel grain conveying mechanism and grain rotation cardan shaft structurally is set, just reached that millet straw automatically separates and grain passes on the purpose that falls into large bamboo or wicker basket automatically, and do not needed the artificial screening straw and manually grain is packed in the large bamboo or wicker basket, reduced harmful dust suction, alleviate operator's labour intensity greatly, improved operating efficiency; Improved work situation, it is a kind of thresher machine of desirable farmland operation.
