Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of crop stalk plucker, comprise, support wheel 1, support bar 2, pad 3, bolt 4, clamp nut 5, supporting frame 6, duplex chain wheel 7, fixed cover 8, link 9, V-type frame 10, left driving shaft 11, right driving axle 12, double strand chain 13, floating pressing plate 14, spring 15, limited block 16, support frame as described above body 6 is connected with link 9 by V-type frame 10, described link 9 is provided with fixed cover 8, supporting frame 6 is connected with minitype motivation chassis by fixed cover 8, front positioning type is adopted when the present invention is connected with minitype motivation chassis, during operation, the position of above about 200mm is shown at the position of chain front end clamping stem stalk at soil.
Dual-chain clamping mechanism mainly contains supporting frame 6, duplex chain wheel 7, left driving shaft 11, right driving axle 12, double strand chain 13, floating pressing plate 14, spring 15, limited block 16, these parts constitute the working portion pulling out stalk, double strand chain 13 side by side parallel is installed, form clamping gap, duplex chain wheel 7 drives two secondary double strand chains 13 to move in the same way under left driving shaft 11 and right driving axle 12 drive, and chooses for clamping and transmits stem stalk.
Floating pressure device, mainly comprise, floating pressing plate 14, spring 15, limited block 16, be arranged on the inner side of double strand chain 13, when pulling out stalk operation, stem stalk moves in chain track, the clamping force between spring 15 Automatic adjusument two double strand chain 13, to adapt to the stem stalk of different-diameter, can successfully it be extracted from soil under the prerequisite ensureing not damaged stem stalk.
Sprocket wheel elasticity adjusting mechanism, mainly comprises, pad 3, bolt 4, clamp nut 5, and the end pad 3 of one end of bolt and sprocket shaft is fixed, and changing bolt length and regulates centre-to-centre spacing between duplex chain wheel 7, controlling chain degree of tightness dynamics by turning clamp nut 5.
Stem stalk plucker advances under the drive of draw-gear, the transmission of Power output difference is to left driving shaft 11 and right driving axle 12, two drive shaft speed are identical, and turn to contrary, the duplex chain wheel 7 be arranged on two driving shafts rotates and drives the double strand chain 13 on it synchronously to move upward.Stem stalk enters from A, start to enter chain retained part at distance soil table 200mm right position, along with chain moves obliquely, stem stalk is subject to the chucking power of two double strand chains 13 and mutual squeezing action and pulling capacity upwards, be pulled out from soil gradually, because the diameter of different stem stalk is different, now floating pressing plate 14 extrudes in the middle part of chain under the Automatic adjusument effect of spring 15, ensure that effective chucking power of chain and suitable friction and Extrusion, make stem stalk be unlikely to lack friction and produce skidding, finally can be pulled out smoothly.After stem stalk is pulled out from soil, along with chain moves together, be transported to clamping chain end gradually, finally can be loaded collecting box by follow-up function or carry out cutting and grinding and make resource reclaim recycling.
