Abstract
The utility model relates to a crusher, in particular to a novel double-roller crusher which comprises a hopper. A driving roller and a driven roller are arranged below the hopper and fixedly connected on a fixed shaft seat and a movable shaft seat respectively, a discharge port is arranged between the driving roller and the driven roller, the movable shaft seat is slidably arranged between an upper rail and a lower rail, a hydraulic oil cylinder seat is arranged between the upper rail and the lower rail, a hydraulic oil cylinder is arranged on the hydraulic oil cylinder seat and acts with the movable shaft seat, and an oil way inside the hydraulic oil cylinder is connected with an energy storer. According to the technical scheme, the double-roller crusher can lower working intensity for operating personnel and is convenient to remotely control and digitally manage.
Description
Technical field
The utility model relates to a kind of disintegrating machine, relates in particular to a kind of novel double-roll crusher.
Background technology
Double-roll crusher on the domestic and international market all adopts spring as the load protection of double-roll crusher discharge gate.Referring to Figure of description 1, because the double-roll crusher drive roll is fixed, adjust the size that roller can be regulated into (row) material mouth, spring 33 is as overload protection.Spring 33 holds out against (prestressing force) by threaded mandrel 44, and normal (medium hardness building stones) work of guaranteeing is carried and how to be passed through, in case run into the iron block overload, effectively protects through spring, makes other (portion) accessory of machine exempt from destruction.But the roll crusher machine is big, and load is big, and the push rod bolt holds out against through manual type that oneself is very difficult.
So in order to reduce operating personnel's working strength, for the ease of remote control and regulation and digital management, we spy has developed hydraulic means.
Summary of the invention
The utility model provides a kind of novel double-roll crusher at deficiency of the prior art.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Double-roll crusher, comprise hopper, the below of hopper is provided with drive roll and driven voller, is provided with discharge gate between drive roll and the driven voller, and drive roll and driven voller are fixedly connected on respectively on dead axle seat and the moving axis seat, the moving axis seat be located at get on the right track and lower railway between, the moving axis seat get on the right track and lower railway between slidably, get on the right track and lower railway between be provided with the hydraulic jack seat, the hydraulic jack seat is provided with hydraulic jack, hydraulic jack and the effect of moving axis seat, the hydraulic jack internal oil passages is connected with accumulator.
Building stones fall into discharge gate between drive roll and the driven voller through hopper, through being squeezed into the product that presets, drive roll is stationary roll, by motor, reductor provides specified rotating speed and moment of torsion, driven voller provides the hydraulic fluid pressure energy by Hydraulic Station to oil cylinder, reaches oil cylinder piston and carries out controlled telescopic variation, makes the moving axis seat drive driven voller and carries out the adjusting of discharge gate size.When hydraulic control, during apparatus overload, carry out overload protection by accumulator.When apparatus overload, discharge gate amplifies, and it is mobile backward that driven voller drives the moving axis seat, and hydraulic cylinder piston is moved in hydraulic jack, and hydraulic oil in the extruding cylinder body forces hydraulic oil to enter accumulator.After overload, accumulator is compressed into hydraulic jack again with hydraulic oil, makes discharge gate get back to origin-location and original pressure.
As preferably, hydraulic jack acts on the center of moving axis seat.Act on the center, make the moving axis seat stressed evenly, the seismism of unbalance stress can not occur.
As preferably, accumulator hangs on the side frame of disintegrating machine.The setting of accumulator does not influence use and the floor space of whole double-roll crusher.
According to the double-roll crusher of the technical solution of the utility model, reduce operating personnel's working strength, also be convenient to remote control and regulation and digital management.
Description of drawings
Fig. 1 is prior art constructions schematic diagram of the present utility model.
Fig. 2 is the structural representation of double-roll crusher of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the utility model is described in further detail:
Double-roll crusher, comprise hopper 1, the below of hopper 1 is provided with drive roll 3 and driven voller 5, be provided with discharge gate 2 between drive roll 3 and the driven voller 5, drive roll 3 and driven voller 5 are fixedly connected on respectively on dead axle seat 4 and the moving axis seat 6, moving axis seat 6 be located at get on the right track 11 and lower railway 7 between, moving axis seat 6 get on the right track 11 and lower railway 7 between slidably, get on the right track 11 and lower railway 7 between be provided with hydraulic jack seat 10, hydraulic jack seat 10 is provided with hydraulic jack 9, hydraulic jack 9 acts on the center of moving axis seat 6, and hydraulic jack 9 internal oil passages are connected with accumulator 8, and accumulator 8 hangs on the side frame of disintegrating machine.
Building stones fall into discharge gate 2 between drive roll 3 and the driven voller 5 through hopper 1, through being squeezed into the product that presets, drive roll 3 is stationary roll, by motor, reductor provides specified rotating speed and moment of torsion, driven voller 5 provides the hydraulic fluid pressure energy by Hydraulic Station to oil cylinder, reaches oil cylinder piston and carries out controlled telescopic variation, makes moving axis seat 6 drive driven voller 5 and carries out the adjusting of discharge gate 2 sizes.When hydraulic control, during apparatus overload, carry out overload protection by accumulator 8.When apparatus overload, discharge gate 2 amplifies, and it is mobile backward that driven voller 5 drives moving axis seat 6, and hydraulic cylinder piston is moved in hydraulic jack 9, and hydraulic oil in the extruding cylinder body forces hydraulic oil to enter accumulator 8.After overload, accumulator 8 is compressed into hydraulic jack 9 again with hydraulic oil, makes discharge gate 2 get back to origin-location and original pressure.
In a word, the above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
