Abstract
The utility model discloses a stubble -cleaning heavy duty harrow single -leaf spring landing leg integrated configuration, the protection device comprises an installation pedestal, a protection cover installation plate, a driving shaft, three shaft sleeves and a driven shaft, the blade is installed through the landing leg to the installation base, the installation base is divided into base and lower base two parts, install the lead screw down on the base, be connected with upper plate and spring on the lead screw, the utility model has the advantages of: the protection blade is meetting the problem that receives the damage under the condition of stone, and the installation is dismantled conveniently, the maintenance of being convenient for, and bearing seal is good, has prolonged life, has improved work efficiency.
Description
Technical field
This utility model relates to a kind of heavy duty harrow supporting leg, specifically a kind of stubble-cleaning heavy duty harrow single-leaf spring supporting leg combinative structure, belongs to heavy duty harrow supporting leg field.
Background technology
Traditional heavy duty harrow is that between square shaft, pipe blade supporting leg is combinative structure, forms overall blade group, structure bulky, dismounting trouble, not easy-maintaining.During work, composite entity rotates, and the most directly can cause supporting leg bearing damage due to square shaft, and leg shaft bearing poor sealing, service life is short.If blade runs into stone breakage problem often occurs.
Utility model content
In order to solve the problems referred to above, this utility model devises a kind of stubble-cleaning heavy duty harrow single-leaf spring supporting leg combinative structure, it is to avoid blade is damaged in the case of running into stone, easy installation and removal, it is simple to maintenance, bearing seal is good, extend service life, improve work efficiency.
The technical solution of the utility model is:
Stubble-cleaning heavy duty harrow single-leaf spring supporting leg combinative structure, including mounting seat, described mounting seat is provided with blade by supporting leg, described mounting seat is divided into upper bed-plate and lower bottom base two parts, on described lower bottom base, leading screw is installed, connect on described leading screw and have upper plate and spring, when blade is pressed onto stone when, blade moves upward, while the change of supporting leg angle, lower bottom base pulls downward on leading screw compression spring, at this moment plays the effect of buffering, automatically restores to operating position by the tension force effect supporting leg of spring afterwards.
Further, the both sides of described blade are stepped up by two, left and right bearing block, two bearings being mounted side by side it are provided with in two described bearing blocks, a fixing axle it is provided with in two described bearings, one end of described fixing axle is through the hole on described supporting leg, described fixing axle one end is provided with screw thread, is fixed on described supporting leg by nut check；Being provided with spacer sleeve between described bearing and supporting leg, when nut check, bearing and a leg pressing spacer sleeve play the effect of fixing bearing, and spacer sleeve and axle are tight fits.
Further, one end of described supporting leg is welded in mounting seat and carries angle when welding.
Further, described bearing block uses double-channel sealing structure, it is not easy to enter soil；Described bearing uses and carries sealing bearing, it is not easy to damage, highly reliable.
During installation, blade fore-and-aft direction above-below direction is simultaneous with angle, and effect of burying is more preferable.
The utility model has the advantage of: by arranging spring bumper, the problem that protection blade is damaged in the case of running into stone, easy installation and removal, it is simple to maintenance, bearing seal is good, extends service life, improves work efficiency.
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment；
Fig. 2 is the schematic perspective view of this utility model embodiment；
Fig. 3 is the sectional view of this utility model embodiment bearing block.
Detailed description of the invention
Hereinafter preferred embodiment of the present utility model is illustrated, it will be appreciated that preferred embodiment described herein is merely to illustrate and explains this utility model, be not used to limit this utility model.
Embodiment 1
As Figure 1-3, a kind of stubble-cleaning heavy duty harrow single-leaf spring supporting leg combinative structure, including mounting seat, described mounting seat is provided with blade 6 by supporting leg 4, the both sides of described blade 6 are stepped up by two, left and right bearing block 13, it is provided with two bearings being mounted side by side in two described bearing blocks 13, connect in two described bearings and have a fixing axle 11, one end of described fixing axle 11 is through the fixing hole on described supporting leg 4, described fixing axle 11 one end is provided with screw thread, described screw thread is provided with locking nut 16, is fixed on described supporting leg 4 by nut check；Being provided with spacer sleeve between described bearing and supporting leg, when nut check, bearing and a leg pressing spacer sleeve play the effect of fixing bearing, and spacer sleeve and axle are tight fits.
One end of described supporting leg is welded in mounting seat and carries angle when welding.
Described mounting seat is divided into upper and lower two parts i.e. upper bed-plate 5 and lower bottom base 1, the latter half of of upper and lower base is fixed by pin, pin can be up and down as rotary shaft, on described lower bottom base 1, leading screw 20 is installed, connect on described leading screw 20 and have upper plate 23 and spring 22, when blade is pressed onto stone when, blade moves upward, while the change of supporting leg angle, lower bottom base pulls downward on leading screw compression spring, at this moment play the effect of buffering, automatically restore to operating position by the tension force effect supporting leg of spring afterwards.
Described bearing block 13 uses double-channel sealing structure, it is not easy to enter soil；Described bearing uses and carries sealing bearing, it is not easy to damage, highly reliable.
