Further, the said first threshing assembly comprises first threshing cylinder, is evenly equipped with several first threshing nail bars on first threshing cylinder, and first threshing cylinder below is provided with first concave grate; The said second threshing assembly comprises second threshing cylinder, is evenly equipped with several second threshing nail bars on second threshing cylinder, and second threshing cylinder below is provided with second concave grate.
Further, said backgauge structure is the baffle plate that is located between first concave grate and second concave grate, and baffle plate one end is fixed on the threshing body, leaves spacing between the baffle plate other end and the threshing body, and this spacing is the said ferry of crossing.
Further, said first guide frame is to be located at first threshing cylinder top to be first gib block that axial screw distributes, and the channeling direction of first gib block points to baffle plate; Said second guide frame is to be located at second threshing cylinder top to be second gib block that axial screw distributes, and the channeling direction of second gib block points to baffle plate.
Further, the diameter of said first threshing cylinder is greater than the diameter of second threshing cylinder.
Further, the rotating speed of said first threshing cylinder is less than the rotating speed of second threshing cylinder.
The beneficial effect of the utility model: adopt the twin-roll sheller unit; The cereal of relatively good threshing is accomplished threshing in the first threshing assembly; The cereal of difficult threshing carries out the threshing second time sending into the second threshing assembly, and two threshing assemblies synchronous workings have improved threshing efficiency; Grain threshing is thorough more, clean, and grain loss is little; Need not to carry out cereal and take off again, reduced farming personnel's working strength.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explanation:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
With reference to Fig. 1,2; Twin-roll axial threshing device comprises threshing body 1, and threshing body 1 front side is provided with charging aperture 10; Threshing body 1 rear side is provided with straw outlet 11; Be provided with the first threshing assembly 2, be provided with between the second threshing assembly, 3, the first threshing assemblies 2 and the second threshing assembly 3 near straw outlet 11 places and be provided with the backgauge structure near charging aperture 10 places in the threshing body 1, be provided with the ferry between backgauge structure and the threshing body 1; The first threshing assembly, 2 tops are provided with first guide frame, and the second threshing assembly, 3 tops are provided with second guide frame; First guide frame cooperates the first threshing assembly 2 that unthreshed cereal is sent into the second threshing assembly 3 through the ferry, and the foreign material that said second guide frame cooperates the second threshing assembly 3 to deviate from are sent into straw outlet 11.
The first threshing assembly 2 comprises that being evenly equipped with several first threshing nail bar, 21, the first threshing cylinders, 20 belows on first threshing cylinder, 20, the first threshing cylinders 20 is provided with first concave grate 22.
The second threshing assembly 3 comprises that being evenly equipped with several second threshing nail bar, 31, the second threshing cylinders, 30 belows on second threshing cylinder, 30, the second threshing cylinders 30 is provided with second concave grate 32.
First threshing nail bar 21 and second threshing nail bar 31 all adopt screw fastening, can increase and decrease installation according to feed quantity, cereal kind etc.
The backgauge structure is the baffle plate 4 that is located between first concave grate 22 and second concave grate 32, and baffle plate 4 one ends are fixed on the threshing body 1, leaves spacing 7 between baffle plate 4 other ends and the threshing body 1, and this spacing 7 is the said ferry of crossing.
