Abstract
The utility model discloses a floating type micro-grain impurity-removing sieve-shaking device. The floating type micro-grain impurity-removing sieve-shaking device comprises a sieving net (5) and an eccentric driving device (10). The sieving net (5) is arranged below an outlet of a grain conveying channel (1) and an elastic supporting device is arranged under the two ends of the sieving net (5). The elastic supporting device is connected with the eccentric driving device (10) and an impurity-removing plate (4) is arranged on top of the sieving net (5). According to the floating type micro-grain impurity-removing sieve-shaking device, the eccentric driving device is adopted to drive the sieving net with the impurity-removing plate to float up and down, and at the same time, the sieving net swings back and forth to achieve the sieve-shaking effect. Therefore, the eccentric driving device enables the impurities on the sieving net to 'bounce' successively toward the direction of the outlet and the impurities are pushed off by the impurity-removing plate from the sieving net. The purposes of grain separation and impurity elimination are achieved. The floating type micro-grain impurity-removing sieve-shaking device is simple in structure, easy to work and high in impurity-removing efficiency and enables a miniature combine harvester to truly achieve the one-step finished operation of harvest, threshing, sieving and impurity-removing, reduces the trouble that the operation of impurity-removing is separated from the operation of threshing, and avoids the improvement of the production cost.
Description
Technical field
The utility model belongs to the grain-sorting mechanism technical field, is specifically related to a kind of floating type miniature cereal removal of impurities that is suitable for containing after the threshing cereal sorting impurities removing of foreign material and trembles screen device.
Background technology
Micro combined rice harvester advantages of small volume, simple in structure, operate light, but it connects grain mouth feed track and header is rigidly connected, and along with the header elevating movement, feed track, connects the curved motion of grain mouth.Because feed track floats, the power transmission difficulty, this type combine can't be provided with screen cleaning device always, and the percentage of impurity of the cereal of harvesting threshing is very high always, has brought very big trouble for follow-up separation, the removal of impurities of cereal.Therefore, developed a kind of simple in structurely, easy and simple to handle, the floating type completely miniature cereal removal of impurities of foreign material sorting is trembled screen device and is very important, and has a extensive future.
The utility model content
It is a kind of simple in structure that the purpose of the utility model is to provide, and it is light to work, and screen device is trembled in the floating type completely miniature cereal removal of impurities of foreign material sorting.
The purpose of the utility model is to realize like this; Comprise screen cloth and eccentric driving device; Described screen cloth is arranged at cereal feed track outlet below; Below, described screen cloth two ends is provided with resilient supporting unit, and described resilient supporting unit connects eccentric driving device, and described screen cloth top is provided with the removal of impurities plate.
Screen cloth swing when fluctuating that the utility model adopts eccentric driving device to drive and has the removal of impurities plate produces the effect of trembling sieve; Make that foreign material " are beated " to the impurity outlet direction successively on the screen cloth; And pushed away screen cloth by the removal of impurities plate, reach separation cereal, the purpose of impurities removing.The utility model is simple in structure, and it is light to work, and it is high that foreign material are rejected efficient, makes miniature combine harvester realize that really harvesting, threshing, sub-sieve remove auxiliary work and once accomplish, and has reduced after the threshing trouble of removal of impurities separately, has avoided the raising of production cost.
