Embodiment
Below, based on accompanying drawing, embodiments of the present invention are described in detail.
Fig. 1 is the overall schematic three dimensional views of ceding of Taiwan structure, and Fig. 2 is straw shift wheel left view, and Fig. 3 is straw shift wheel right view.As shown in Figure 1-2, this straw shift wheel (12) comprises group straw (121), fixing width dish (122a), eccentric width dish (122b), rice crop-poking wheel axis (123), semi-disc (124), support gyroaxis (not shown), anti-tangle frame (126), tensioning combination (127), straw shift wheel strut (128) and strut slide (129) etc.The function of straw shift wheel (12) be by the ceding of Taiwan before crop be allocated to cutter (13) and cut off, and the crop of cutting off is dialled be poured in the ceding of Taiwan (1), straw shift wheel (12) is conducive to propping up laid crop, reduces to dial the strike of grain ear and reducing and chooses careless phenomenon when straw (121) is mentioned.
Rice crop-poking wheel axis (123) is provided with the fixing width dish (122a) of branch shape near the both sides of axle head, and power intake is positioned at the right side of straw shift wheel (12), near the eccentric width dish (122b) that side of power intake being set with branch shape.Dial straw (121) across being installed in parallel on the fixing width dish (122a) of branch shape of the left and right sides, the right-hand member dialling straw (121) is welded with eccentric spindle nose (121a), and left end is welded with movable spindle nose (121b).As Figure 1 and Figure 4, eccentric spindle nose (121a) is in Z-shaped, and the fixing width dish (122a) of the branch shape of its one end connection bit in the right side of straw shift wheel (12), the other end connects the eccentric width dish (122b) of branch shape.
As shown in Figure 3, the semi-disc (124) at inclination angle before and after adjustable rice-pulling tooth (121c) is also equipped with in one end of setting-up eccentricity width dish (122b).Semi-disc (124) is made up of roller (124a) and semicircle adjustment disk (124b), wherein semicircle adjustment disk (124b) is provided with pivoted housing (124b1), on the sheathed excircle being fixed on rice crop-poking wheel axis (123) of pivoted housing (124b1), roller (124a) is fixed by bolts on semicircle adjustment disk (124b), and by the cylindrical portion (122b1) that roller (124a) is stuck in eccentric width dish (122b), its cylindrical portion (122b1) along eccentric width dish (122b) is done relative motion.During side-looking, rice-pulling tooth (121c) straight down, when gathering in laid crop, being transferred to and being tilted backwards 15 ~ 30 ° by rice-pulling tooth (121c), when gathering in the crop of Gao Ermi, is transferred to by rice-pulling tooth (121c) and turns forward 15 °.
As shown in Figure 1, shown in Figure 5, straw shift wheel (12) can be bearing in rotationally and be arranged on the left and right supporting arm (129a) of the straw shift wheel strut (129) swung up and down on header frame (11) rear-side cross member (113b) via horizontal cross.Straw shift wheel strut (129) left and right supporting arm (129a) is arranged in the concentric circles that first circular clip (113c) and cover plate (113d) formed, and the rice crop-poking wheel axis (122) in supporting arm (129a) outside on the right side of direction of advance is also provided with power input wheel (127a).The anti-tangle circle preventing from twining grass between fixing width dish and straw shift wheel strut is welded with inside strut sliding sleeve on the right side of described straw shift wheel direction of advance.
The middle part of cam-action reel strut (129) two supporting arm (129a) is provided with the Connection Block (129a1) connecting support cylinder (129b), its front and back position should ensure that cam-action reel (12) swings up and down scope, when straw shift wheel (12) rises to the highest, crown distance cutter (13) of minimum rice-pulling tooth (121c) should be greater than 370mm, when straw shift wheel (12) is down to minimum, the crown of rice-pulling tooth (121c) is preferably made to touch ground for guaranteeing to prop up laid crop.The front end of straw shift wheel strut (129) two supporting arm (129a) is provided with multiple jack can regulate the front and back position of straw shift wheel (12), for ensureing that straw shift wheel (12) its minimum point in adjustable range can touch ground, straw shift wheel strut (129) two supporting arm (129a) is designed to reclinate arc.As shown in Figure 8, strut slide (129) is welded by strut mount pad (129b) and anti-tangle circle (129a).Anti-tangle circle (129a) prevents fixing width dish and twines grass between (122a) and straw shift wheel strut (129), in order to avoid stuck straw shift wheel.
As shown in Figure 6, dial straw (121) by the pipe of holing at regular intervals (121d), two ends be the eccentric spindle nose (121a) of parallel band edge short cylinder, the movable spindle nose (121b) in band edge short cylinder is welded.After seam, side-looking pipe axis, eccentric spindle nose (121b) and the band edge short cylinder of pipe (121d) welding ends and the band edge short cylinder concentric of pipe (121d) and movable spindle nose (121b).Multiple rice-pulling tooth (121c) runs through in the boring of inserting pipe (121d).For easy to connect with raising seedling-erecting performance, run through the rice-pulling tooth (121) inserting pipe (121d) and be designed to " door " shape, and with certain radian, during side-looking, to bend inwardly.For improving intensity and the bending resistance of both sides rice-pulling tooth (121c), the diameter of first, second rice-pulling tooth (121c1) of both sides is greater than the diameter of the rice-pulling tooth (121c2) of middle part; Or the strength of materials of first, second rice-pulling tooth (121c1) of both sides is greater than the strength of materials of the rice-pulling tooth (121c2) of middle part.The micro-Z-shaped connection of eccentric spindle nose (121a) is pulled center line and is overlapped with the projection that pipe (121d) cross section runs through the line extended line of jack or become to be less than the angle of 10 °.
As shown in Figure 1, during installation, the band edge short cylinder of movable spindle nose (121b) is movably connected in the branch top of the fixing width dish (122a) of the branch shape of support side by u tie (122b2) and bolt (122b3); The band edge short cylinder of eccentric spindle nose (121a) and pipe (121d) welding ends is movably connected in the branch top of the fixing width dish (122a) of the branch shape of power input side by u tie (122b2) and bolt (122b3); The parallel end band limit short cylinder of eccentric spindle nose (121a) is movably connected in the branch top of eccentric width dish (122b) by u tie (122b2) and bolt (122b3).In addition, for avoiding twining grass, anti-tangle frame (126) is also equipped with in fixing width dish (123) outside of support side and the outside of eccentric width dish (124), covers the parallel end band limit short cylinder being arranged on all movable spindle nose (121b) on the fixing width dish (122a) of support side and the eccentric spindle nose (121a) on power input side bias width dish (122b) respectively.As shown in Figure 7, anti-tangle frame (126) is welded by umbellate form connecting plate (126a) and L-type connection strap (126b).Umbrella shape connecting plate (126a) becomes regular pentagon to distribute, and L-type connection strap (126b) is that connection two umbellate form connecting plates (126a) make it fix, and makes anti-tangle frame (126) become regular pentagon.
Although the present invention discloses as above with preferred embodiment; so itself and be not used to limit the present invention; those skilled in the art without departing from the spirit and scope of the present invention, can carry out suitable amendment and variation, and therefore protection scope of the present invention is when being as the criterion of defining depending on claim.
