Described upper and lower transverse onveyer is to be equipped with to dial on endless band to refer to.

At hoisting equipment place, described cutting bed end, be provided with baffle plate.

Described threshing cylinder is a rasp bar cylinder, and its rasp bar becomes screw type.

Up-small and down-big between described cylinder sieve with the spacing of threshing cover.

On described cylinder shaft, have assorted surplus group of finger.

Combine described in the utility model is simple in structure, and is in light weight, and institute's wasted work rate is little, is particularly suitable for splat and uses.

Fig. 1 is the schematic diagram of combine described in the utility model;

Fig. 2 is the schematic diagram of cutter sweep;

Fig. 3 is the partial sectional view of threshing cleaning unit.

Referring to Fig. 1 and Fig. 2, combine described in the utility model has cutting bed 1, hoisting equipment 2 and threshing cleaning unit 3.Described cutting bed has chassis 4 and cutter sweep.Described cutter sweep has the cutter of deciding 5, moving cutter 6, upper and lower transverse onveyer 7,8.Have a driving shaft 18 on the chassis, driven shaft 19 is equipped with moving cutter 6 on driving shaft 18, the driving wheel of upper and lower transverse onveyer 7,8 and hoisting equipment, and the driven pulley that moves cutter 6 and upper and lower transverse onveyer 7,8 is installed on the driven shaft.Like this, moving cutter 6, the rotating speed of upper and lower transverse onveyer 7,8 is identical, but the diameter of the driving wheel of moving cutter 6 is greater than the diameter of upper and lower transverse onveyer 7,8 driving wheels, thereby the linear velocity of moving cutter 5 is greater than the linear velocity of upper and lower transverse onveyer.Described moving cutter 5 is sawtooth that are equipped with separated by a distance on a wide for no reason chain, and its sawtooth is long to be 8-12mm, is generally the length of 2-3 pitch of chain, and the about 8-10mm of its spacing is the length of 2-3 pitch of chain.Described upper and lower transverse onveyer is to be equipped with to dial on endless band to refer to that its endless band can be a V belt.Described hoisting equipment has conveyer belt 20 and elevator case 21.Described conveyer belt 20 is to have riser on wide belt, is installed in the elevator case, so that the straw after will cutting is transported to sheller unit.The hoisting equipment place has baffle plate in the cutting bed end, in case straw splashes.This baffle plate can be installed on the elevator case 21, also can be installed on the chassis 1.Because driving wheel and the moving cutter 3 and the upper and lower transverse onveyer 4 of conveyer belt 20,5 driving wheel is coaxial, its diameter is greater than upper and lower transverse onveyer 7,8 driving wheel, therefore, the linear velocity of conveyer belt is greater than the linear velocity of upper and lower transverse onveyer, and its conveying capacity is greater than the conveying capacity of upper and lower transverse onveyer.

Referring to Fig. 3, described threshing cleaning unit has threshing cylinder 9, fan 11, cylinder sieve 10, threshing cover 13 and scourclean 15.Threshing cylinder 9 is a rasp bar cylinder, is installed in the cylinder sieve 10.Fan 11 is installed in the axle head of the axle of threshing cylinder 9.Has dividing plate 12 between cylinder and fan.On the axle of cylinder 9, also having assorted surplus group and referring to 22, so that outside the cane dial-out machine after the threshing.10 one-tenth cylindrical shapes of cylinder sieve, the one end has the straw inlet, and the other end has the cane outlet, is installed in the threshing cover 13, and both spacings are up-small and down-big.Described threshing cover is a cylindrical shape, and cylinder is provided with funnel shaped discharging opening.Described scourclean has charging aperture, has a mesh screen that tilts in tube, and scourclean is divided into the stock part and goes out hetero moiety, and the charging aperture 16 of this scourclean is sleeved on the discharging opening periphery of threshing cover, and spacing between the two should be greater than 20mm..There is a ventilation duct 14 to extend below the mesh screen of scourclean at the end with fan 11 of threshing and cleaning cover, so that wind is delivered to mesh screen.During work, cutting bed bottom surface overhead 20cm. begins cutting.Because the diameter of the driving wheel of moving cutter 3 is greater than the diameter of upper and lower transverse onveyer 4,5 driving wheels, machine advances, straw upper end under being cut relies on transverse onveyer 4, again since the linear velocity of upper and lower transverse onveyer 4,5 less than the linear velocity of moving cutter 3, therefore straw forms heeling condition and is sent to hoisting equipment, sends into threshing cleaning unit by hoisting equipment again.Because the rubbing effect between the outer mesh screen 10 of threshing cylinder 9 and cylinder, the wheat that enters on the straw of threshing cleaning unit is promptly got off by rubbing from the wheat head, the funnel part that mesh by cylinder sieve 10 enters threshing cover 13 enters some broken cane and grieshoch simultaneously.Because the effect of fan 11, wind blows below the mesh screen to scourclean 15 through ventilation duct 14, light broken cane and the grieshoch compass screen surface 17 that blown off, annular spacing through between the discharging opening of charging aperture 16 and threshing cover 13 blows out, wheat enters the stock case by sieve aperture, and at the scourclean 15 ports mouth of putting out cereal, this mouth can be provided with one, to edge of a field unloading, also pocket can be enclosed within mouthful last loading of putting out cereal.And heavy, size glides along compass screen surface greater than the various foreign material of wheat, falls ground through impurity outlet.

Combine described in the utility model goes for small tractor, also can be used for large sized tractor.When being used for small tractor, its cutter sweep can be driven by another small-sized motivation.
