Abstract
The utility model belongs to agricultural machinery, in particular to a secondary cleaning device of a grain combine harvester. The utility model has the technical scheme that the secondary cleaning device of a grain combine harvester comprises a vibrating sieve, wherein the vibrating sieve is arranged between a barn and a pushing auger; a vibrating sieve driving device connected with the vibrating sieve is connected with the top end of the pushing auger through a belt; a material outlet of the vibrating sieve is connected with a material inlet of a trash recovery auger; a material outlet of the trash recovery auger is connected with a threshing roller, and one end of the trash recovery auger is connected with the pushing auger through the belt. The power is provided by the harvester self,and the new power source does not to be added, so the structure is simple; the threshing percentage is greatly enhanced; and the trash content is decreased.
Description
Technical field
The utility model belongs to agricultural machinery, relates in particular to a kind of secondary cleaning plant of grain combine.
Background technology
In the now general grain combine, cereal comes out from threshing chamber, threshing cylinder, be raised device through the seed behind the cleaning room and directly send into silo, in said process, can only remove the long shoot bar, and also have foreign material such as certain clever chaff, crushing straw in the seed, and plant the landlord and can not directly dry envelope storehouse, back, also to manually raise again one time, so not only increased workload, the effect of removing is also bad.
Summary of the invention
The purpose of this utility model is, at the deficiencies in the prior art, and provide a kind of secondary cleaning plant of grain combine, this device is installed a vibratory sieve at the silo top, provide power by grain header itself, do not increase new power source, simple in structure, the most rate of taking off of threshing improves greatly, and percentage of impurity reduces.
For solving the problems of the technologies described above, the technical solution of the utility model is: the secondary cleaning plant of grain combine, comprise at silo and push vibratory sieve between the screw feeder, the vibratory sieve transmission device that is connected with vibratory sieve is connected with the top that pushes screw feeder by belt, the vibratory sieve discharging opening is connected with the charging aperture of assorted surplus recovery screw feeder, the discharging opening of assorted surplus recovery screw feeder is connected with threshing cylinder, an end of the described surplus recovery screw feeder of mixing by belt with push screw feeder and be connected.Power comes from the grain header top and pushes screw feeder, power divides two-way: the one tunnel passes to the vibratory sieve transmission system drives the vibratory sieve reciprocating motion, assorted surplus recovery screw feeder is passed on another road, the assorted surplus crop that vibratory sieve is collected out is transported to threshing cylinder by assorted surplus recovery screw feeder and carries out threshing once more, cleans, advance silo through the seed elevator, circulation goes round and begins again.
Described vibratory sieve transmission device comprises the drive pulley that is connected with belt, and drive pulley is connected with eccentric wheel by power transmission shaft, and the eccentric shaft on the eccentric wheel is connected with shaker shoe pitman on the vibratory sieve.Push screw feeder like this and drive drive pulley by belt and rotate, drive pulley drives eccentric wheel by power transmission shaft and rotates, and the shaker shoe pitman that is connected with eccentric shaft on the eccentric wheel moves reciprocatingly like this, and gyration has been transformed into reciprocating motion.
The beneficial effects of the utility model are: by pushing screw feeder power is passed to vibratory sieve, vibratory sieve is moved back and forth, the clean seed silo that bled.Push screw feeder simultaneously and give assorted surplus recovery screw feeder transmission of power, will send into threshing cylinder from clever chaff, crushing straw that vibratory sieve comes out and carry out threshing once more.This scheme is in the normal harvest process of combine harvester, assorted surplus crop in the seed can not enter silo influences the seed cleannes, can not lose in vain again, guarantees that the seed cleannes in the grain header silo improve on former basis greatly, this structural design is simple, and is convenient and practical.
Description of drawings
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is the plan structure schematic diagram of Fig. 1.
Among the figure: the 1-vibratory sieve, 2-pushes screw feeder, 3-silo, 4-shaker shoe pitman, 5-eccentric shaft, 6-eccentric wheel, 7-power transmission shaft, 8-drive pulley, 9-belt, 10-vibratory sieve discharging opening, the 11-surplus recovery screw feeder of mixing, 12-threshing cylinder.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Embodiment
According to illustrated in figures 1 and 2, the secondary cleaning plant of grain combine, comprise at silo 3 and push vibratory sieve 1 between the screw feeder 2, the vibratory sieve transmission device that is connected with vibratory sieve 1 is connected with an end that pushes screw feeder 2 by belt 9, vibratory sieve discharging opening 10 is connected with the charging aperture of assorted surplus recovery screw feeder 11, the discharging opening of assorted surplus recovery screw feeder 11 is connected with threshing cylinder 12, an end of the described surplus recovery screw feeder 11 of mixing by belt 9 with push screw feeder 2 and be connected.The vibratory sieve transmission device comprises the drive pulley 8 that is connected with belt 9, and drive pulley 8 is connected with eccentric wheel 6 by power transmission shaft 7, and the eccentric shaft 7 on the eccentric wheel 6 is connected with shaker shoe pitman 4 on the vibratory sieve 1.
