Description
Technical field
The utility model relates to screening machine field, particularly relates to a kind of cereal screening machine.
Background technology
In rural households, the cereal (as wheat) of harvesting, containing impurity such as the more grains of sand and stones, needs could to process after cereal and these magazins' layout further.Current rural households mainly adopt artificial hand picked mode to be separated, and not only efficiency is low, labour intensity large, and are separated not thorough, impact screening grain quality.Although there is a lot of cereal screening machine in the market, these equipment are used for processing factory of enterprise, and device structure is complicated, expensive, area occupied large, are not suitable for family and use.
Therefore be necessary to develop a kind of cereal screening machine, the screening of cereal machine automatization can be realized, increase work efficiency, reduce hand labor intensity, the quality of screening cereal is guaranteed, and mechanism is simple, easy to use, is suitable for family and applies.
Utility model content
Select the inconvenience of cereal impurity and the deficiency of existing cereal screening machine for rural households are manual, the utility model provides the cereal screening machine that a kind of structure is simple, easy to operate, operating efficiency is high, cheap.
For reaching above-mentioned purpose, a kind of cereal screening machine of the utility model, comprises actuating unit, sieve and frame, described actuating unit comprises motor, little straight spur gear, large straight spur gear, crank, straight pin, connecting rod and slide block, described motor is positioned on the boss of described frame, described motor connects little straight spur gear by power transmission shaft, described little straight spur gear is connected with a joggle large straight spur gear, described large straight spur gear is by bolster connecting crank, there is the connecting rod connected by straight pin matched in clearance all sides of described crank, the middle part of described connecting rod other end connection sliding block, described frame top end face is provided with narrow-long groove track, described slide block is placed in the narrow-long groove track of described frame top end face, sieve is provided with above described slide block, described slide block can drive sieve to move around.
Wherein said sieve is rectangle, is screen cloth bottom it.
Wherein said connecting rod is elongate rod, and respectively there is circular hole at its two ends, is connected respectively by straight pin with crank and slide block, forms revolute pair.
Wherein said slide block 10 is made up of three slide bodies, and cross section is T-shaped; A middle slide body there is circular hole, for being connected by straight pin with connecting rod 8, forming revolute pair.
The utility model achieves following technique effect: can fast by the magazins' layout of smaller size smaller in cereal out, and structure is simple, and volume is little, easy to use, is applicable to especially remote mountain village family of rural households
Below in conjunction with accompanying drawing, a kind of cereal screening machine of the utility model is described further.
Accompanying drawing explanation
Fig. 1 is cereal screening machine structural scheme of mechanism.
Fig. 2 is the schematic diagram of mechanism of the actuating unit top view of cereal screening machine.
Description of reference numerals: 1-sieve; 2-frame; 3-motor; The little straight spur gear of 4-; The large straight spur gear of 5-; 6-crank; 7-straight pin; 8-crank; 9-straight pin; 10-slide block; 11-power transmission shaft; 12-back shaft.
Detailed description of the invention
Below in conjunction with drawings and Examples, to above-mentioned being described in more detail with other technical characteristic and advantage of the utility model.
As shown in diagram 1, for a kind of cereal screening machine, be made up of actuating unit, sieve and frame, described actuating unit comprises motor 3, straight spur gear 4,5, crank 6, straight pin 7,9, connecting rod 8 and slide block 10, described sieve 1 is rectangle, bottom is screen cloth, for by the granule magazins' layout in cereal out, be placed on above slide block 10, described frame 2 is square, boss is had below inwall, for laying motor 3, porose on sidewall, for supporting shaft and back shaft, top end face there is narrow-long groove, for the track as slide block 10.
As shown in Figure 2, actuating unit comprises motor 3, little straight spur gear 4, large straight spur gear 5, crank 6, straight pin 7, connecting rod 8, straight pin 9, slide block 10, power transmission shaft 11 and back shaft 12, described motor 3 provides power for cereal screening machine, be placed on the boss of frame 2, its rotating shaft is power transmission shaft 11, described power transmission shaft 11 one end is connected with motor 3, the other end is provided with little straight spur gear 4, described little straight spur gear 4 and large straight spur gear 5 form reducing gear, motor 3 higher rotation speed is transformed to the comparatively slow-speed of revolution and passes to crank 6 by back shaft 12, described back shaft 12 is provided with large straight spur gear 5 and crank 6, described crank 6 is disk, there is an aperture in the edge of crank, for forming revolute pair with straight pin 7 matched in clearance and connecting rod 8, crank 6 rotates thus drivening rod 8 moves, described connecting rod 8 is elongate rod, respectively there is circular hole at two ends, by straight pin 7, 9 respectively with crank 6, slide block 10 forms revolute pair, connecting rod 8 Sports band movable slider 10 is along rail moving, described slide block 10 is made up of three slide bodies, cross section is T-shaped, a middle slide body there is circular hole, for forming revolute pair with connecting rod 8, slide block 10 is placed in the narrow-long groove track of frame 2 top end face, and move around along it, slide block 10 moves and drives the sieve 1 be placed on it to move, thus the granule foreign material in cereal are separated.
When using practical this Novel grain screening machine, cereal is placed upside down in sieve 1, open the power switch of motor 3, sieve 1 moves back and forth on the track of frame 2 with slide block 10, thus by magazins' layout more short grained in cereal out, turn off electric motor power switch time clean Deng cereal, cereal is poured out from sieve.
Above-described embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
