Embodiment

Referring to Fig. 1～Fig. 8: this straw harvesting machine, comprise frame, nearside divider 6, straw shift wheel 20, through cross side to the clamping convey device that can carry to the rear of walking machine (can same prior art), cutter 1, mechanical driving device, after the rear portion of side direction clamping chain is provided with stalk, fell to device.Fell behind the stalk to the device for its compacted position above the clamping chain backward the elasticity of corner hold up standing grain to turn to depression bar 14 (seeing Fig. 4, Fig. 5), simple, effective.Fell behind the stalk and also held up the standing grain guide post, can establish one or 2 (figure part omitted) around the corner to device.Falling to device behind the stalk can also be (seeing Fig. 1, Fig. 2, Fig. 3): be provided with acceleration chain wheel 11 on the axle of chain driving wheel 8, acceleration chain wheel 11 is connected with guider minor sprocket 9 by quickening chain 10, guider minor sprocket 9 is contained on the removable elastic rod beam 7, the structure of removable elastic rod beam 7 is: have two sprocket wheel spacing bull sticks, two sprocket wheel spacing bull sticks are by inverted U-shaped bar and elasticity is housed holds up the rod member of standing grain depression bar 18 (or elasticity holds up standing grain guiding depression bar 14, effect with) to link to each other; Guider minor sprocket 9 is contained in an end of spacing bull stick.It both can be to tractor dead astern lay stalk, also can be according to situation to tractor right back lay stalk.1, cutter 1 (see figure 6) is 4 above rotary cutting knifes among 2 embodiment, the circular saw bench cross lamination of adjacent two rotary cutting knifes.See Fig. 1, Fig. 4, Fig. 5 (annotate: the vertical view of Fig. 1 right half is with the right half of Fig. 5), nearside divider 6 is that triangular shape is board-like; Laterally reaching the side direction clamping convey device is the clamping chain conveyor, the clamping chain is provided with short moving tooth 16, be provided with a long moving tooth 17 every 3～5 short moving teeth, the holding up of clamping chain side is fixed with a row pressure on the standing grain depression bar fixed mount 25 and holds up standing grain depression bar 18 to the elasticity of chain; Laterally the front end of (or oblique) and side direction clamping convey device is contained on the preceding movable frame 5, the rear end is contained on the movable frame 23 of back, preceding

movable frame

5 and 3 of forebaies are provided with lifting

adjustable mechanism

4, and 25 of back movable frame 23 and afer bays move up and down adjustable structure; Preceding movable frame 5, back movable frame 23 can be split type or Contiuum type, are contained on the tractor by forebay 3, afer bay 25.The power of the ceding of Taiwan is spread out of by the belt pulley of tractor diesel engine, passes on the belt pulley on the frame of front by the V-belt, passes to ceding of Taiwan gear-box 21 through preceding universal joint 19 again, and the V-belt does not change when making taiwan cut off and landing.If use two-way guider, when needs when stalk is placed in the tractor dead astern, right and left is turned to position as shown in Figure 2 to device, stalk by removable elastic rod clamping and the transmission of quickening chain 10 is transported to the tractor dead astern and left the speed of giving reaches purpose at tractor dead astern lay.When needs during to tractor right back lay, two-way device is turned to position as shown in Figure 3, stalk is held when being transported to acceleration chain wheel 11 decontrols clamping, and is accelerated the speed that chain 10 gives to right and reaches in the tractor right back or the purpose of right side side's lay.

During work, facility are walked forward, and chain 15 motion drives straw shift wheel 20 rotations, and stalk is forced to deliver to the place ahead of chain through nearside divider 6, straw shift wheel 20, and the elasticity that is installed on the support holds up standing grain depression bar 18 to push down, in case its lean forward, side falls.When on top stalk was brought under control, the cutter 1 in the ceding of Taiwan cut off the root of stalk.When chain 15 moved backward, stalk will be carried until guider thereupon backward after cutting off, and was directed to device and selects to dishing out, and lay is in the dead astern or the right back of tractor.The power of carrier chain is by the output of tractor rear drive sprocket, through transmission case 13, reaches the driving wheel 8 of chain again through rear universal joint 12; The power of cutter is by the main frame output ceding of Taiwan driving wheel 2 on forebay, reaches ceding of Taiwan gear-box 21 in the ceding of Taiwan through preceding universal joint 19, reaches cutter 1 by gear-box again.

Through on probation, effect is fine.
