Abstract

The utility model discloses a micro rice thresher which comprises a thresher frame, a winnower, a thresher cover hood, a threshing roller, a dynamic gasoline or a dynamic diesel engine, a vibration sieve, a transmission belt and a belt pulley. The utility model is characterized in that the dynamic gasoline engine or the dynamic diesel engine drives the threshing roller to drive the winnower to winnow and drive a deflection mechanism to left and right pull the vibration sieve to sieve grains. Clean grains are winnowed out from the winnower to be sacked. Rice leaves and sundries are pushed out from the upper side of the vibration sieve. The utility model has the advantages of simple and reasonable structure and low manufacture cost, and the threshing efficiency is higher more than 30% than the threshing efficiency of a congener machine. The utility model threshes grains 700 kilograms / hour, and a distance between the thresher bottom and the ground is 150 mm. The machine body is 900 multiplying 500 multiplying 1000, and the thresher weight is 60 kilograms or so. The utility model which can cleanly separate the rice leaves, weeds and the grains is an ideal micro rice thresher in an agricultural machine thresher class.

Description

The miniature rice threshing machine

The utility model belongs to the agriculture machine threshing machine, particularly a kind of miniature rice threshing machine.

Existing threshing machine has full-automatic threshing machine and half mechanized threshing machine.Half mechanized threshing machine hand fed, foot pedal head roll degrain, labour intensity is big like this, and efficient is not high enough, and also the handlebar foot pedal changes the motor power driving into recently, adds the spiral propeller rotation the crowded blower fan of releasing of grain is sent the dress bag.This has improved production efficiency greatly, welcome by society, still, because its driven by motor cylinder shelling and spiral propeller rotate its transmission speed ratio and are not easy to cooperate suitable the use, cause mechanism huge, heaviness lifts on the frame and shake to sieve to be mounted in, thereby be added to the height space of fuselage, element part easily produces fatigue, causes unreasonable structure, hampers the raising of production efficiency, oil consumption height in the running, 500 kilograms of low shellings of efficient/time.Full-automatic threshing machine is owing to automatically need oil consumption big, and fuselage is overweight, and price is also high.These defectives are also treated further raising.

It is a kind of simple and reasonable that the purpose of this utility model is to provide, low cost of manufacture, shelling efficient height, 700 kilograms/time, fuselage is lightly attractive in appearance, heavily about 60 kilograms of machine, overhead apart from 150mm, oil consumption is hanged down 100 kilograms/0.1 kilogram at the bottom of the machine, and price is lower than similar 30% miniature rice threshing machine.

Technical solution of the present utility model is such, comprise by frame, winnow, cover cover, shelling cylinder, gasoline or diesel powered, the sieve that shakes, driving belt, belt pulley, the driving belt big belt pulley is loaded on an end of shelling drum shaft, and big belt pulley is a two-groove belt pulley.A groove thongs and is connected transmission with the belt pulley of vapour, diesel powered output shaft; Another groove of big belt pulley thongs and is connected transmission with an axle head belt pulley of winnow.The one axle head dress of shelling cylinder shakes and sieves the small belt pulley of swing mechanism, the small belt pulley of shelling cylinder connects the eccentric small belt pulley of transmission by driving belt, upwards there is an eccentric wheel in the footpath of small belt pulley, eccentric wheel is connected with the carriage center holder axle at the sieve end that shakes, connecting eccentric wheel has connecting rod between the sieve collet axle with shaking, and holder axle overhead is in shaking one of front and back, the sieve end, and the carriage holder axle of the holder axle of back is connected transmission with connecting rod, and being connected transmission with rocking bar, rocking bar is swung around the rocking bar core semicircular arc.Rocking bar core is installed on the frame, corresponding to the position that the shelling cylinder is installed two elongated slots are arranged on the frame face, but the bearing block of shelling cylinder dress be fixed in elongated slot axial adjustment shelling cylinder to power belt apart from length, the winnow outer wall is welded into the radian angle of R30～120 degree to folder with two boards, transition arc connection between the front and back swash plate of bucket at the bottom of the Lougu, the about R30 of circular arc～150 degree, but punch forming or welding.

The utility model has the advantages that simple and reasonable, low cost of manufacture, shelling efficient is higher more than 30% than similar, 700 kilograms of shellings/time, overhead apart from 150mm, body 900 * 500 * 1000, machine are heavily about 60 kilograms at the bottom of the machine, can separate clean pack to paddy rice clothing, weeds with millet, be the desirable miniature rice threshing machine of agricultural machinery threshing machine class.
