Description

The full-automatic two Portable rice threshing machines that separate of " fixed network " formula millet straw

The utility model relates to a kind of agricultural thresher machine, particularly is furnished with two Portable rice threshing machines that separate vibrating screen and human-machine dual-purpose device.

At present, during the results paddy rice of vast rural area, generally continue to use backward old-fashioned rice thresher, this facility volume is big, heavy, labour intensity is big, and grain runs off serious, can not carry out the millet straw separation.The manpower multifunctional portable rice thresher that Chinese patent 92212215.6 is announced, its volume is less, weight is lighter, but the structure more complicated realizes adopting when millet straw separates wheel band driven type structure, and three groups of wheel bands are housed, be that drive belt moves separate mesh integral body through main shaft drive separate mesh drive reposefully, often make that dropping on grain on the separate mesh can not be vibrated and cross net and descend, the millet straw separation is not thorough, causes grain loss.Simultaneously because broken grass is involved in the separate mesh race and can causes net, and the separate mesh wheel has resistance slightly, and the driving-belt rope just stops operating along with elongating, practice shows that this rice thresher operation and maintenance wastes time and energy very much.The fixed net type millet straw by my design through Patent Office of the People's Republic of China's approval separates the Portable rice threshing machine patent, the patent No. 97208260.3, and this rice thresher is simple in structure, volume is little, in light weight, the efficient height, for once millet straw separates, still be mingled with more grain in the millet straw after the separation, lose greatlyyer, need further the personnel selection work point to waste time and energy again from millet straw, and can not realize that manpower is motor-driven dual-purpose, labour intensity is big.

The purpose of this utility model is to provide a kind of " fixed network " formula millet straw full-automatic two Portable rice threshing machines that separate, accomplish that volume is big, in light weight, rational in infrastructure, saving of labor, laborsaving, efficient can automatically separate by very clean realization millet straw, operating maintenance is convenient, labour intensity is little, and grain loss is very little, manpower, motor-driven dual-purpose.

The purpose of this utility model is to realize like this.The full-automatic two Portable rice threshing machines that separate of this " fixed network " formula millet straw are by pedal and support, yoke, a left side, right millet baffle, back millet baffle, back grain-blocking cloth, a left side, careless cloth is blocked on the right side, last millet baffle, retaining paddy bulletproof cloth, in block careless guided plate, the careless deflector of outer retaining, wood paddy bucket, the cuckoo bucket, last grain-blocking cloth, manpower drive unit and motor-driven transmission device, it is characterized in that adopting fixedly mesh screen and movable mesh screen to combine and form the first separation device, promptly below thrasher, arc surface along thrasher is provided with a fixedly mesh screen, be connected and fixed the screw apical axis by movable net then and fuse with the movable mesh screen in back, whole wire side covers the cross section of rice thresher thrasher.Movable mesh screen with movable net transmission cramp bar promotes separate mesh by the travelling gear combination through movable net connecting rod and does upper and lower vibration, realizes that millet straw separates for the first time.It comprises that also is installed in the careless deflector of an outer retaining lower end, by the secondary separation mesh screen, and the secondary separation device that secondary separation net connecting rod, the combination of secondary separation net travelling gear, secondary separation net cramp bar etc. are formed." bow " shape tooth is set, apart from left and right side millet baffle gap 1-2mm on the round frame of rice thresher thrasher.Above-mentioned manpower drive unit is made up of pedal and support, kinematic link, gear wheel, pinion, steelframe etc.Motor-driven transmission device is swept careless plate etc. by motor-driven drive, diesel engine, thrasher, waterproof anti-sticking and is formed.

After above-mentioned realization millet straw separates for the first time, be sieved into wooden paddy bucket through movable mesh screen vibration grain and go into basket via cuckoo bucket water conservancy diversion, simultaneously, broken grass, spikes of rice etc. are thrown into rapidly on the fixedly mesh screen of thrasher, because thrasher high speed rotating, under the effect of strong centrifugal force and threshing tooth, after spike of rice in the broken grass impacted once more, blocking careless guide plate water conservancy diversion in the broken grass warp enters on the secondary separation mesh screen, promote through secondary separation net travelling gear compound action and connecting rod again, on the secondary separation mesh screen is done, following vibration is screened through wooden paddy bucket water conservancy diversion millet baffle water conservancy diversion grain residual in the broken grass once more and is gone into basket, and broken grass is discharged automatically, fall on the base plate of pedal support, realize the separation once more of millet straw.

The utility model is compared background technology and is had following characteristics:

1, volume is little, in light weight, rational in infrastructure, working service convenient.

2, millet straw automatically separates, and separates thoroughly; The work efficiency height, and reduced labour intensity.

But 3 manpowers, motor-driven dual-purpose, as long as pull down the manpower kinematic link when motor-driven, the starting facility just can move; When power or power do not have fault to keep in repair,, pull down diesel engine and get final product as long as load onto the manpower kinematic link.This machine can be used as the threshing of paddy rice and wheat.
