The invention relates to a grader lower end main shaft supporting device and belongs to the technical field of grader lower end main shaft supporting device structures. The grader lower end main shaft supporting device comprises a clutch claw installed on the outer portion of a grader and connected with a spiral shaft of the grader and a clutch shaft matched with the clutch claw in use. The clutch claw is connected with a hanging ring. The other end of the clutch shaft is installed in a sliding way seat. A shifting fork used for driving the clutch shaft to slide laterally along the sliding way seat is installed on the sliding way seat. A locking screw which achieves the locking and locating functions is further arranged on the sliding way seat. The grader lower end main shaft supporting device is reasonable in structural design, capable of preventing a rolling bearing from being corroded and abraded by water and sand in a groove, long in service life, low in accident rate and capable of saving resources.
Description
Technical field
The present invention relates to a kind of grader lower end main shaft support device, belong to grader lower end main shaft support apparatus structure technical field.
Background technology
At present, the helical axis lower end axis of rolling bearing portion of grader is arranged in tank, though existing rolling bearing pedestal design sealing good be unable to undergo soaking into of cement sand can very quick-wearing, easily cause and stop production and change parts.
Above-mentioned design is through using for many years, after it is found that its shortcoming, reform into again rubber plain bearing housing or nylon plain bearing housing, although cost is lower, easy to maintenance, but its harm is very large, because it is without sealing device, very fast bore is worn into elongated hole, after wearing into elongated hole gradually, helical axis parts also and then decline gradually, the bearing value of plain bearing housing is almost eliminated, weight all concentrates in helical blade outer rim, the silt particle harder by bottom land supports, due to the supporting of silt particle, helical blade wearing and tearing are also very fast, and helical axis parts part weight can produce very large resistance by silt particle supporting completely, larger for driving section loss, because supporting portion is conjugated, after producing larger resistance, helical axis also produces thereupon and radially bends, lower slider support holes is ground into elongated hole, often there is disconnected macro-axis accident in spire, cause the off-time long, wealth, thing, manpower waste greatly, very undesirable.
Summary of the invention
The object of the invention is to the weak point solving the existence of above-mentioned prior art, a kind of reasonable in design is provided, rolling bearing can be ensured not by the husky etch of trough inner water and wearing and tearing, long service life, accident rate is low, the grader lower end main shaft support device economized on resources.
The present invention is achieved through the following technical solutions:
Grader lower end main shaft support device, its special character be to comprise be installed on the outside and clutch pawl 4 be connected with the helical axis 1 of grader of grader, with clutch pawl 4 with the use of clutch shaft 7, clutch pawl 4 is connected with suspension ring 5, the other end of clutch shaft 7 is installed in slideway base 17, slideway base 17 being provided with the fork 10 for driving clutch shaft 7 to horizontally slip along slideway base 17, slideway base 17 being also equipped with the tie down screw 11 of locking positioning effect;
Described clutch shaft 7 is provided with filler chamber 6 near one end of clutch pawl 4, is sealed between filler chamber 6 and clutch shaft 7 by filler 18, filler chamber 6 is provided with filler chamber's gland 8;
Described clutch shaft 7 is provided with bearing block 13 and bearing block gland 15 near one end of slideway base 17, and bearing block 13 is fixedly connected with by round nut 14 and bearing 16 with bearing block gland 15;
The below of described grader is provided with cell body 19, and slideway base 17 is connected with cell body 19 by support post;
Described slideway base 17 is provided with the fork support 12 for fixing fork 10.
Grader lower end of the present invention main shaft support device, reasonable in design, each part fits uses, and can ensure rolling bearing not by the husky etch of trough inner water and wearing and tearing, need not change parts of bearings, ensure life-span maximum use, more can ensure normal production, can not have an accident, helical axis be operated more better than existing design, not easily broken macro-axis, reduction expense and accident stop production the loss caused, and have good application prospect.

Detailed description of the invention
Provide the specific embodiment of the present invention below with reference to accompanying drawing, be used for that the present invention is described further.
Embodiment 1
The grader lower end main shaft support device of the present embodiment, comprise be installed on the outside and clutch pawl 4 be connected with the helical axis 1 of grader of grader, with clutch pawl 4 with the use of clutch shaft 7, helical axis 1 is provided with support 3 and blade 2, clutch pawl 4 is connected with suspension ring 5, the other end of clutch shaft 7 is installed in slideway base 17, slideway base 17 being provided with the fork 10 for driving clutch shaft 7 to horizontally slip along slideway base 17, slideway base 17 being also equipped with the tie down screw 11 of locking positioning effect; Clutch shaft 7 is provided with filler chamber 6 near one end of clutch pawl 4, is sealed between filler chamber 6 and clutch shaft 7 by filler 18, filler chamber 6 is provided with filler chamber's gland 8; Clutch shaft 7 is provided with bearing block 13 and bearing block gland 15 near one end of slideway base 17, and bearing block 13 is fixedly connected with by round nut 14 and bearing 16 with bearing block gland 15; The below of grader is provided with cell body 19, and slideway base 17 is connected with cell body 19 by support post; Slideway base 17 is provided with the fork support 12 for fixing fork 10.
Operation principle: when ore dressing plant system equipment overhaul stops production time, when helical axis 1 if desired promotes, only the screw at shaft flange place is unloaded, drive clutch shaft 7 along slideway base 17 internal slide by fork 10, thus make clutch shaft 7 away from clutch pawl 4, now, helical axis 1 is promoted, if not repairing cell body 19 leak, as far as possible by solids emptying in cell body 19 by suspension ring 5, flange screw can not be unloaded, the trouble that also need not promote.
Beneficial effect of the present invention:
1, ensure rolling bearing not by the husky etch of trough inner water and wearing and tearing, parts of bearings need not be changed, ensure life-span maximum use, more can ensure normal production, can not have an accident;
2, ensure that helical axis running is than intrinsic ideal, not easily broken macro-axis, cost saving and accident stop production the loss caused;
3, through improving rear blade light abrasion, long service life, investment reduction.
