Abstract
The utility model relates to a vibration sieve device for a miniature paddy rice combined harvester, which is a special device in the grain outlet casing of the miniature paddy rice combined harvester. The vibration sieve device adopts the structure that a sieve plate is connected with a transmission shaft and a swing shaft through a support frame and then is tightly fixed by a bolt on the grain outlet through a bearing support. The vibration sieve device is driven by a chain wheel through the output of the upper chain wheel axle of a scrapping plate chain; and the backward and forward movement of the vibration sieve is carried out by an eccentric shaft connecting swing lever on the chain wheel through the transmission shaft, so that sundries are vibrated out of from a sundry outlet from the sieve plate. Because the chain wheel is connected with a blower by using the chain, dust is blown out from the sundry outlet simultaneously. Therefore, grains outflowing from a grain outlet are clean and have extremely low trash content. The vibration sieve device is applicable to the miniature paddy rice combined harvester as a sundry removing device.
Description
Technical field
The utility model relates to the vibrating screen device of a kind of parts of combine, particularly miniature rice combine-harvester.
Background technology
China mountain area, hills area area are bigger, and the mountain region terraced fields are a lot, and the field piece is little, and since agriculture-countryside-farmer's policy execution, the enthusiasm that the peasant plants ground increases and cultivated area is big more, and big with traditional harvesting tool harvester for rice wheat labour intensity, operating efficiency is very poor.Along with the development of agricultural machinery, the miniature rice combine-harvester development was very big in recent years.But it is exactly the percentage of impurity height that there is common shortcoming in miniature harvester, though some machinery has designed blower fan, percentage of impurity is also than higher.Existing market requires high to the cereal cleannes of grain header, but still fails suitable solution in the prior art.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of vibrating screen device that reduces the miniature combine harvester percentage of impurity is provided.
The utility model is realized with following mode:
A kind of vibratory sieve of miniature rice combine-harvester, it has housing, flight chain, sprocket wheel, sprocket shaft and blower fan, it is characterized in that eccentric shaft is arranged on the sprocket wheel, sieve plate connects power transmission shaft and swinging axle through support respectively by bearing pin, power transmission shaft and swinging axle respectively through bearing block and bolted on grain header grain outlet housing diverse location, the fork two ends connect power transmission shaft and swing arm respectively, the swing arm other end connects eccentric shaft, bearing pin makes sieve plate be connected with power transmission shaft with swinging axle through support, swinging axle is fastened on the position that position on the grain header grain outlet housing is higher than power transmission shaft, sprocket shaft output transmission by swing arm make vibratory sieve can before and after back and forth movement.
The vibratory sieve of dress in the utility model grain header grain outlet housing, the paddy that flight chain is carried up falls on sieve plate, and the miscellaneous object outlet that shakes of the foreign material in the paddy, good paddy flows down on sieve plate by vibration.This vibration screen device effectively reduces the percentage of impurity of the outer paddy of grain header outlet, and it is suitable for miniature harvester and does the impurity removing device use.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail
In the utility model combine grain outlet housing 8 vibratory sieve is housed, it connects power transmission shaft 5 and swinging axle 4 by sieve plate 1 respectively through support 2 usefulness bearing pins 3, power transmission shaft 5 and swinging axle 4 are fixed tightly in diverse location on the grain header grain outlet housing 8 respectively through bearing block 6 usefulness bolts 7, fork 17 two ends connect power transmission shaft 5 and swing arm 13 respectively, swing arm 13 other ends connect eccentric shaft 10, eccentric shaft 10 is by carrying sprocket shaft 11 output sprocket wheel 12 transmissions on the flight chain 9, sprocket wheel 12 is housed on sprocket shaft 11, connect swing arm 13 by the eccentric shaft on the sprocket wheel 12 10, make by power transmission shaft 5 through fork 17 to come and go running before and after the vibratory sieve, the foreign material in the paddy that flight chain 9 is carried come up are gone out from miscellaneous object outlet 14 by vibratory sieve.Connect blower fan 16 by sprocket wheel 12 usefulness chains 18, blower fan 16 is run well cooperate vibrating screen device to drop to the percentage of impurity in the cereal minimum.The cereal that grain outlet 15 places are flowed out is very clean.
