Abstract

The utility model belongs to the field of agricultural machinery, especially, relate to a twin drum rice combine. The technical scheme of the utility model is that: double drum rice combine, including shale shaker, frame, the horizontal axial compressor cylinder and the concave sieve that are located the frame, the horizontal axial compressor cylinder that is located the frame includes preceding cylinder and rear drum, and there is the drum shaft preceding, the inside of rear drum, is connected through the chain between two cylinders, has feeding port and row grass mouth respectively on preceding, the rear drum, and preceding cylinder row grass mouth is corresponding with rear drum feeding port, preceding, the rear drum below corresponds respectively has preceding, back concave sieve. The threshing and separating distance is doubled compared with the original distance, thus not only improving the threshing rate, the yield and the productivity of the rice threshing operation, but also reducing the loss of the threshing operation and improving the production efficiency.

Description

The twin-roll rice combine

Technical field

The utility model belongs to agricultural mechanical field, relates in particular to a kind of twin-roll rice combine.

Background technology

China paddy rice plantation area is wide, and various places output just differs, and is wide in variety, and some paddy rice (as the stalk rice) is difficult to threshing.Existing corn mowing machine; it is main mostly being single threshing cylinder, limited by type, and drum length and concave grate separating area increase limited; during the harvesting paddy rice; the effective travel of threshing is short, and threshing is bad with the effect of separating, and is not bad adaptability; it is exactly the percentage of damage height; entrainment loss is serious, and field loss is big, and threshing performance, the seed rate of recovery and clean rate are not high.

Summary of the invention

The objective of the invention is to, deficiency at present technology, and provide a kind of twin-roll rice combine, this scheme is added with a threshing cylinder parallel with former cylinder in vertical side of original threshing cylinder, make threshing and the distance of separating grow one times than originally, not only improved the rice threshing operation threshing performance, add yield and productivity ratio, but also reduced the loss of threshing operations, improved production efficiency.

For solving the problems of the technologies described above, the technical solution of the utility model is: the twin-roll rice combine, involving vibrations sieve, frame, be positioned at lateral shaft stream roller and concave grate on the frame, the lateral shaft stream roller that is positioned on the frame comprises front roll and back roll, there is drum shaft the inside of forward and backward cylinder, be connected by chain between two cylinders, feeding mouth and straw outlet are arranged respectively on the forward and backward cylinder, the front roll straw outlet is corresponding with the back roll feeding mouth, below the described forward and backward cylinder respectively to forward and backward concave grate should be arranged.Cereal enters from the front roll feeding mouth, move on threshing on one side in cylinder, separation one side straw outlet direction vertically, crop to front roll straw outlet place, under centrifugal action, throw in the back roll from the back roll feeding mouth, the threshing on one side of crop in the back roll, separation Yi Bian move to straw outlet vertically, are discharged from the shelling body to straw outlet place cane.

Chain described in the utility model is connected the end of forward and backward drum shaft.Front roll directly drives back roll by chain, and forward and backward cylinder is worked simultaneously, and front roll straw outlet and back roll feeding mouth interface are not stopped up,

Vibratory sieve described in the utility model be positioned at before concave grate and the back concave grate below.Fall on the vibratory sieve 7 through seed and thin foreign material (clever shell etc.) that forward and backward drum threshing, concave grate separate, under the acting in conjunction of blower fan 10 and vibratory sieve 7, seed is separated,

The beneficial effects of the utility model are: the twin-roll rice combine, involving vibrations sieve, frame, be positioned at lateral shaft stream roller and concave grate on the frame, the lateral shaft stream roller that is positioned on the frame comprises front roll and back roll, there is drum shaft the inside of forward and backward cylinder, be connected by chain between two cylinders, feeding mouth and straw outlet are arranged respectively on the forward and backward cylinder, and the front roll straw outlet is corresponding with the back roll feeding mouth, below the described forward and backward cylinder respectively to forward and backward concave grate should be arranged.Because side by side former and later two lateral shaft stream rollers on the frame, and corresponding two concave grates are arranged, like this under the situation that does not change the grain header width, the length of threshing cylinder and concave grate separating area can nearly double, threshing and disengaging time have correspondingly been increased, greatly improve the threshing and the separating property of grain header, reduce the seed loss.

Description of drawings

Fig. 1 is a structural representation of the present utility model,

Fig. 2 is the vertical view of Fig. 1.

Among the figure: concave grate before the 1-front roll, 2-, 3-chain, 4-back roll, concave grate behind the 5-, 6-frame, 7-vibratory sieve, 8-drum shaft, 9-front roll straw outlet, 10-back roll feeding mouth, 11-back roll straw outlet, 12-front roll feeding mouth.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

Embodiment

According to illustrated in figures 1 and 2, the twin-roll rice combine, involving vibrations sieve 7, frame 6, be positioned at lateral shaft stream roller and concave grate on the frame 6, the lateral shaft stream roller that is positioned on the frame 6 comprises front roll 1 and back roll 4, before, there is drum shaft 8 inside of back roll, the end of two drum shafts 8 is connected by chain 3, before, feeding mouth and straw outlet are arranged respectively on the back roll, front roll straw outlet 9 is corresponding with back roll feeding mouth 10, below front roll 1 and the back roll 4 respectively to preceding concave grate 2 should be arranged, before back concave grate 5, vibratory sieve 7 are positioned at concave grate 2 and back concave grate 5 below.Cereal enters from front roll feeding mouth 12, move on threshing on one side in front roll 1, separation one side front roll straw outlet 9 directions vertically, crop to front roll straw outlet 9 places, under centrifugal action, throw in the back roll 4 from back roll feeding mouth 10, the threshing on one side of crop in the back roll, separation Yi Bian move to back roll straw outlet 11 vertically, are discharged from the shelling body to back roll straw outlet 11 place's canes.
