Abstract
The invention belongs to agricultural machinery technological field, particularly the clear grass of the reverse differential of one servo-actuated wedge shape shovel disc surfaces, native device.Disc shaft is connected with disk by axle sleeve; Disk upper surface center arranges gearcase, installs gear shaft in gearcase; Gear wheel is sleeved on disc shaft, and pinion is sleeved on gear shaft, and engages with gear wheel; One end of gear shaft is through gear lid, and to shovel one end affixed with the wedge shape of " Z " type; During work, disk rotational and then drive disc shaft rotate, and the disc shaft of rotation drives wedge shape shovel to rotate backward in disc surfaces by gear train and gear shaft, reaches the object of cleaning disc surfaces weeds and earth.The gearcase device being arranged on disc surfaces is modularized design, and structure is simple, installation, convenient disassembly, and can be directly installed on existing disk coulter.
Description
Technical field
The invention belongs to agricultural machinery technological field, particularly relate to the clear grass of a kind of reverse differential servo-actuated wedge shape shovel disc surfaces, native device.
Background technology
At present, no-tillage seeding machine is being exempted from, is being widely used with minimal tilling, and plough, as its critical component, directly affects the quality of sowing and the operating efficiency of machine.What, consistency of soil many in weeds was high exempts from, when minimal tilling farmland operation, plough surface is often stained with many weeds and earth, will affect the normal work of plough so to a certain extent, thus have impact on seeding quality.Existing clear soil, careless device mainly fixedly mount scraper on plough backplate, and the scraper being close to disc surfaces just can remove earth when disk rotational, but add the working resistance of plough so simultaneously, and easily make soil block and the stuck disk of weeds.In addition, also just like the patent No. be ZL200720148432.2 " loose kind of the device of the scraping on a kind of disk coulter assembly " although designed by scraping kind of the device that falls apart eliminated between the two by the gap between increase scraper and disk
Friction, but due to scraper be also fixing, so also do not reach well clear soil, clear careless effect, simultaneously also larger to the disturbance of soil.Therefore needing to design a kind of scraper is motion, and the disk coulter surface weeds little to soil disturbance, power consumption is little and earth scavenge unit, to improve seeding quality.
Summary of the invention
The present invention is in order to problems such as the surface solving existing disk are native clearly, clear careless effect is bad, soil disturbance large, plough working resistance is large, provide the clear grass of a kind of reverse differential servo-actuated wedge shape shovel disc surfaces, native device, on disk coulter surface along with disk rotates together, thus weeds and the earth of disc surfaces can be cleared up.
The technical solution used in the present invention is:
Disc shaft is connected with disk by axle sleeve;
Disk upper surface center arranges gearcase, installs gear shaft in gearcase; Gear wheel is sleeved on disc shaft, and pinion is sleeved on gear shaft, and engages with gear wheel; One end of gear shaft is through gear lid, and to shovel one end affixed with wedge shape;
Wedge shape shovel is " Z " type, and a part of bottom surface and gear lid are fitted, and the bottom surface portions of bending and disc surfaces are fitted.
Described gear lid is connected with gearcase by external screw thread.
Described axle sleeve installs bearing (ball) cover outward, bearing (ball) cover and gearcase by 3 on the equally distributed both sides being bolted to disk of circumferencial direction.
The upper surface of described wedge shape shovel is inclined-plane, reduces gradually from stiff end to free end far away; And the upper surface of wedge shape shovel also possesses a sword face tilted gradually.
Beneficial effect of the present invention is:
The cross section of wedge shape shovel is in " Z " type, and its upper surface is inclined-plane can reduce disturbance to soil and energy ezpenditure as far as possible, and Ye Shi inclined-plane, one side can remove weeds and the earth of disc surfaces preferably; Wedge shape shovelman as time be servo-actuated, namely wedge shape shovel is what to be moved in a circle in disc surfaces under the drive of disk, simultaneously by the commutation of gearcase device and chronotropic action make wedge shape shovel with disk turn to contrary and rotating speed is higher, coordinate wedge shape to shovel two inclined-planes of upper surface and side again, wedge shape is shoveled with passive type without the need to additionally providing power and soil disturbance is little and the feature of active anti-blocking ability well; The gearcase device being arranged on disc surfaces is modularized design, and structure is simple, installation, convenient disassembly, and can be directly installed on existing disk coulter, does not need the plough redesigning, manufacture newtype to have good adaptability and interchangeability.The present invention can be widely used on disc plough.

Embodiment
The invention provides the clear grass of a kind of reverse differential servo-actuated wedge shape shovel disc surfaces, native device, below in conjunction with the drawings and specific embodiments, the present invention will be further described.
As shown in Figure 1, 2, 3, device of the present invention mainly comprises disk 1, axle sleeve 10, disc shaft 2, wedge shape shovel 5 and gearcase 3.
Disc shaft 2 is fixedly connected with the endoporus of axle sleeve 10, and the external cylindrical surface of axle sleeve 10 is fixedly connected with disk 1; Axle sleeve 10 outside is coated by bearing (ball) cover 11.
As shown in Figure 4, disk 1 upper surface center arranges gearcase 3, and gear lid 6 is connected with gearcase 3 by external screw thread; In gearcase 3, gear shaft 9 is installed; Gear wheel 8 is sleeved on disc shaft 2, and pinion 7 is sleeved on gear shaft 9, and engages with gear wheel 8; Bearing (ball) cover 11 and gearcase 33 bolts 4 are fixedly mounted on the two sides of disk 1 respectively.
One end of gear shaft 9 is through gear lid 6, and to shovel 5 one end affixed with wedge shape; Wedge shape shovel 5 is " Z " type, and a part of bottom surface and gear lid 6 are fitted, and fits in the bottom surface portions of bending and disk 1 surface.The upper surface of wedge shape shovel 5 is inclined-plane, reduces gradually from stiff end to free end far away, reduces the disturbance to soil when wedge shape shovel 5 can be made to bury; And the upper surface of wedge shape shovel 5 also possesses a sword face tilted gradually, wedge shape shovel 5 can be made when disk 1 surface pivots to clear up weeds and the earth on disk 1 surface, and the rotating speed of the rotating ratio disk 1 of wedge shape shovel 5 is high.
Operation principle of the present invention is: disk 1 rotates and drives disc shaft 2 to rotate, the disc shaft 2 rotated makes gear wheel 8 rotate and then drives the pinion 7 of engagement to rotate, pinion 7 makes gear shaft 9 rotate together, wedge shape shovel 5 on gear shaft 9 just can reversely rotate on disk 1 surface, the weeds on cleaning disk 1 surface and earth.
Each embodiment is only for illustration of the present invention above; wherein the structure, connected mode etc. of each parts all can change to some extent; every equivalents of carrying out on the basis of technical solution of the present invention and improvement, all should not get rid of outside protection scope of the present invention.
