Abstract
The invention discloses an externally inclined blade type inverted trapezoidal ditching cutter disc and a driving device thereof. A left cutter disc transmission square structure and a right cutter disc transmission square structure which are symmetrically arranged at two ends of a cutter disc main shaft are used for installing a left cutter disc device and a right cuter disc device which are identical in structure; cutter disc supports of the left cutter disc device and the right cutter disc device are installed on the cutter disc main shaft; the cutter disc supports are provided with moving blades through moving blade rotating supports which are arranged on the peripheral circumference; synchronous pins are arranged on the cutter disc supports meanwhile; the synchronous pins and synchronous grooves which are formed in a bearing base are installed in a matching mode; the cutter disc supports drive the moving blades to rotate through the moving blade rotating supports meanwhile the bearing base performs circular motion due to driven of the synchronous pins; accordingly downward internally collecting soil cutting and upward externally inclined soil turning through the moving blades are achieved and finally the inverted trapezoidal ditching is achieved. The externally inclined blade type inverted trapezoidal ditching cutter disc and the driving device thereof have the advantages of thoroughly solving the problems that the traditional reverse spinning type ditching is large in resistance and inverted trapezoidal scraper plough installation in a direct spinning type enables a ditcher to be easy to be blocked, effectively reducing power consumption of the ditcher, enabling soil generated during ditching to fall outside ditches and greatly reducing labor intensity of workers.
Description
Technical field
The present invention relates to agricultural machinery technological field, relate in particular to a kind of outer beat blade type inverted trapezoidal trench digging cutterhead and drive unit thereof.
Background technology
At present, ditching machine can be divided into adverse-rotary type ditching machine and just rotating ditching machine according to trench digging cutterhead and the counterrotating direction of wheel of travelling, and adverse-rotary type ditching machine is that the direction of rotation of trench digging cutterhead and the wheel that travels is contrary, and just rotating ditching machine is identical.Adverse-rotary type ditching machine is because the direction of rotation of trench digging cutterhead and the wheel that travels is contrary, the wheel that travels drives ditching machine to travel forward under the effect of driving force, and thereby the wheel counter-rotating of relatively travelling of trench digging cutterhead produces pulling force backward and makes ditching machine have the trend of motion backward, under the effect of positive and negative two kinds of power, ditching machine travel speed is because the driving wheel that travels trackslips and slight reduction by a small margin.Owing to travelling, wheel speed low driving force is large, the high-drag of trench digging cutterhead rotating speed is little, trench digging cutterhead is expert to sail under the effect of wheel and is forced to promote forward to break ground trench digging, the resultant direction of the power of travelling forward of ditching machine and adverse-rotary type cutterhead is angled downwards with horizontal plane in direction of advance, native to dive when causing trench digging cutterhead to be ditched forward, darker that ditch opens walked in ditching machine overtaking, finally cannot advance; For addressing the above problem, in ditching machine the place ahead, be provided with gauge wheel, for the contrary soil of diving that revolves of ditching machine is controlled to certain scope, due to the latent native characteristic of adverse-rotary type trench digging, the adverse-rotary type ditching machine primary ditching degree of depth is large, and degree of depth uniformity is consistent simultaneously, trench digging cutterhead forwards both sides is thrown soil, bottom of trench after trench digging is clean, neat, and without manual sorting, this rotary tillage ditching mode is used widely in small-sized self-walking ditching machine.Just rotating ditching machine is because trench digging cutterhead is identical with the direction of rotation of the wheel that travels, the common ditching machine that drives of trench digging cutterhead and the wheel that travels advances, forward drive power is large, ditching machine riding stability is good, yet ditching machine travels, the resultant direction of power and just rotating cutterhead is upwards angled with horizontal plane in direction of advance, cause the cutterhead ability of burying, ditching depth differs, of poor quality, and the ditching machine soil that retrojects, the hack covering of newly ditching again, needs special-purpose device to remove, and is generally applied in the ditching machine of large sized tractor traction.
Above-mentioned two kinds of ditching machines are all out upright ditch, thereby after causing trench digging, a large amount of earth is still scattered in slot wedge, and under the effect of rainwater wind-force, loose soil easily slips in ditch from slot wedge, follow-uply need manual amendment, therefore brought high-intensity work and the waste of human resource of repeating.Just rotating ditching machine is drawn by large sized tractor, and driving force is large, and dextrorotation ditching machine can adopt inverted trapezoidal to scrape mouldboard plough, and groove is spread to inverted trapezoidal, and the soil that scraper plate the scrapes cutterhead of being ditched is thrown away again, can realize out inverted trapezoidal ditch.But for small-sized self-walking ditching machine, reverse rotary tillage ditching resistance is large, as use dextrorotation instead and install inverted trapezoidal additional and scrape mouldboard plough, resistance is larger, the more important thing is that installing inverted trapezoidal additional scrapes after mouldboard plough, inverted trapezoidal is scraped the soil block that mouldboard plough scrapes and is deposited in the middle of ditching machine, easily produces and stops up, and the power of the cutterhead that makes to ditch first do not consuming on hack before trench digging, increase power consumption.
Summary of the invention
Technical problem solved by the invention is to provide a kind of outer beat blade type inverted trapezoidal trench digging cutterhead and drive unit thereof, to solve the shortcoming in above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions:
