Description
Technical field
The utility model relates to a kind of harvesting machinery, and especially a kind of high thick stem stalk crop harvester, belongs to agricultural machinery technological field.
Background technology
For realizing effective utilization of crop stem, it is carried out to effectively harvesting is primary link.At present, harvesting technology for short thin stem stalk crop (as paddy rice, wheat and herbage etc.) has been tending towards ripe and perfect, and formed the product of standard and sizing, and the research of the thick stem stalk of height crop (giantreed, high stalk reed, ramie, Chinese sorghum etc.) mechanized harvest is relatively lagged behind.
According to the applicant understood, ramie mechanized harvest mainly lays particular emphasis on the research of mechanization decorticating technology both at home and abroad, and grain header belongs to blank substantially.Broomcorn harvester in use is nearly all to be converted by wheat or rice harvester, and results effect is undesirable.Trace it to its cause, because of the conveying after the thick stem stalk of height crop harvesting, adopt traditional mechanism conscientiously to be ensured.
Retrieval is found, application number is that 98242245.8 Chinese utility model patent discloses a kind of reed harvester, its grain lifter need to start to hold up standing grain and finish to hold up the moment of standing grain to change the direction of motion of holding up standing grain moving tooth, cause producing great acceleration, thereby cause great alternate stress, easy damaged member, cause reliability poor, and a minute standing grain for this machine adopts passive minute traditional standing grain device, can not effectively separate high thick stem stalk crop stem, the normal harvesting of impact, easily generation is stopped up and is caused carrying not smooth.
For another example, application number is that 200920270903.6 Chinese utility model patent discloses a kind of broomcorn harvester, its cross conveyor only adopts conveyer belt to carry, lack grain lifter, easily lodging after Sorghum Stalk cutting, can not effectively be delivered to longitudinal conveying device, this machine is longitudinally carried and only with conveyer belt, is completed in addition, infeasible when growing distance, the conveying of acclive stem stalk.
Summary of the invention
The purpose of this utility model is: the shortcoming existing for above-mentioned prior art, proposes a kind of harvesting and carry steadily high thick stem stalk crop harvester reliably, thereby make this machine can obtain practical applying.
In order to reach above object, the thick stem stalk of height of the present utility model crop harvester comprises the shaving formula horizontal cutting device that is positioned at walking machine frame front lower place, the one group of horizontal profile of tooth conveyer belt being positioned on cutter sweep is set aside standing grain device, by the horizontal pressure clamping convey device of setting aside upper and lower two the horizontal circle carrier chains of standing grain device and forming, the conveying chain type that is positioned at horizontal pressure clamping convey device one side is longitudinally forced clamping convey device, and the collection stalk case that is positioned at longitudinal pressure clamping convey device rear end, its improvements are: also comprise and be positioned at upper group standing grain device of setting aside standing grain device top, the described upper standing grain device of dialling contains the rice-pulling shaft being supported on connection frame, the two ends of the described rice-pulling shaft former that is connected respectively, between two formers by be connected with it and circumferentially uniform one group of Hough seat respectively hinged level dial straw, on described group of straw, be intervally distributed with the grilled teeth radially extending, one end of described rice-pulling shaft is also set with fan-shaped flap, hinged two limited rollers that are positioned in same radius of turn of described fan-shaped flap, the cylindrical of two limited rollers contacts formation radial constraint with kink at the eccentric former middle inside through hole of rice-pulling shaft end, the uniform one group of hinged-support corresponding with Hough seat respectively of the circumference of described eccentric former, extend and axially vertical crank throw one end of the described group of contiguous eccentric former of straw, the other end of each crank throw is hinged with the pivoting support of the eccentric former of vicinity, described fan-shaped flap so that grilled teeth angular position be down fixed on connection frame.
During results, the stem stalk of high thick stem stalk crop enters cutter sweep cutting under the synergy of upper and lower group of standing grain device, and the stem stalk after cut-out is successively delivered to collection stalk case heap productive set under the linking of horizontal and vertical pressure clamping convey device is carried.Afterwards, after the stem stalk in collection stalk case reaches rated weight, height, adopt hydraulic means that hemp stalk is discharged to assigned address.In this process, setting aside standing grain device suitably separates and buttresses stem stalk, guiding stem stalk enters cutter sweep, and the upper straw shift wheel of dialling standing grain device synchronously rotates by turning the eccentric former parts of bent drive, group straw and grilled teeth in straw shift wheel remain direction down, thereby play the desirable standing grain effect of holding up, guaranteed the smooth and easy of harvesting, conveying; And because the direction of motion of moving tooth remains unchanged, therefore avoided alternate stress, guaranteed machine steady operation reliably and with long-term.
