Because adopt said structure, this installs double-stranded clamping device and adopts the parallel side by side installation of a pair of double strand chain, form the clamping gap, duplex chain wheel drives down that two chains move in the same way, is used for clamping and chooses and transmit the stem stalk.
Described floating pressure device is arranged on the inboard of double strand chain, and spring is equipped with in inside, leans on the effect self adaptation of spring force to regulate the clamping force between two double strand chains, to adapt to the stem stalk of different-diameter.
Described sprocket wheel degree of tightness governor motion adopts the bolt and nut form, and an end of bolt and the end pad of sprocket shaft are fixed, and regulates the centre-to-centre spacing between the duplex chain wheel, control chain degree of tightness dynamics through turning nut change bolt length.
Described support wheel is installed in the front end below of device, can not only guarantee the stability of equilibrium of complete machine during operation, and play certain guide effect.
Said driving shaft depends on the power output on small-sized chassis, and the big I of its rotating speed, moment of torsion is utilized the transmission device change according to the planting requirement of crop.
In sum, the present invention is simple and practical, and compact conformation improves the operating efficiency of pulling out stalk effectively, reduces people's labour intensity.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4; A kind of crop stem 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 through V-type frame 10; On the said link 9 fixed cover 8 is installed; Supporting frame 6 is connected with the minitype motivation chassis through fixed cover 8, adopts front positioning type when the present invention is connected with the minitype motivation chassis, and the position about above 200mm is shown at soil in the position of chain front end clamping stem stalk during operation.
Double-stranded clamping device 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; This several sections has constituted the working portion that pulls out stalk; The parallel side by side installation of double strand chain 13; Form the clamping gap, duplex chain wheel 7 drives down at left driving shaft 11 and right driving axle 12 that drive two secondary double strand chains 13 move in the same way, is used for clamping and chooses and transmit the stem stalk.
Floating pressure device mainly comprises, floating pressing plate 14, spring 15, limited block 16; Be arranged on the inboard of double strand chain 13; When pulling out the stalk operation, the stem stalk moves in chain track, and spring 15 self adaptations are regulated the clamping force of 13 of two double strand chains; To adapt to the stem stalk of different-diameter, under the prerequisite that guarantees not damaged stem stalk, can successfully it be extracted from soil.
Sprocket wheel degree of tightness governor motion mainly comprises, pad 3, bolt 4, clamp nut 5, and an end of bolt and the end pad of sprocket shaft 3 are fixing, regulate the centre-to-centre spacing between the duplex chain wheel 7, control chain degree of tightness dynamics through turning clamp nut 5 change bolt length.
Stem stalk plucker advances under the drive of draw-gear; Left driving shaft 11 and right driving axle 12 are given in power output transmission respectively; Two drive shaft speed are identical, and switched in opposite is installed in duplex chain wheel 7 rotations on two driving shafts and the double strand chain 13 that drives on it and moves upward synchronously.The stem stalk gets into from A; Begin to get into the chain retained part in distance soil table position, the 200mm left and right sides, along with chain moves obliquely, the stem stalk receives chucking power and the mutual extrusion effect and the pulling capacity upwards of two double strand chains 13; From soil, be pulled out gradually; Because the diameter of different stem stalks is different, this moment, floating pressing plate 14 pushed the chain middle part under the self adaptation regulating action of spring 15, had guaranteed effective chucking power of chain and suitable friction and Extrusion; Make the stem stalk be unlikely to lack friction and produce and skid, finally can be pulled out smoothly.After the stem stalk is pulled out,, be transported to the clamping chain end gradually along with chain moves together from soil, finally can be through follow-up function with its collecting box or carry out cutting and grinding and do the resource recycling of packing into.
