Abstract
The present invention relates to coal mine fully-mechanized mining crusher actuation techniques field, the hammer mill that specifically a kind of hydraulic motor directly drives, including hammer mill, hydraulic motor and coupling assembly.The hammer mill is to couple the output shaft of hydraulic motor by coupling assembly flat key or spline with the hammer axis of crusher, eliminates multiple large-sized powers such as motor, coupling device and retarder and drive apparatus.The present invention directly drives hammer mill using hydraulic motor; realize the flexible protective to crusher hammer axis; improve hammer axis service life; explosion-proof effect is good; transmission efficiency can be effectively improved, the installation and maintenance link of many equipment originally is reduced, reduces failure rate; cost is greatlyd save, the service requirement of crusher is met.
Description
Technical field
The present invention relates to coal mine fully-mechanized mining crusher actuation techniques field, the hammer crushing that specifically a kind of hydraulic motor directly drives
Machine.
Background technique
Hammer mill is the main raw coal crushing plant of underground coal mine, and coal cinder is rolled using high speed impact, and hammer axis turns
It is fast high, it absorbs impact load and shakes very big and change violent.The driving portion of hammer mill is widely used motor and adds limit square at present
The form of type fluid-flywheel clutch acceleration and deceleration device, there are slip power losses for load limiting type of constant filling fluid coupling, can when not using explosive plug
Explosion accident can be led to, speed adjustable range is narrow, no bending moment ability, and needs to reserve sizable put between motor and retarder
Between emptying.Entirely driving portion takes up space larger, and at high cost, installation and maintenance link is more, high failure rate.
Hammer mill is directly driven using hydraulic motor, makes working media in system by the closed circuit of hydraulic system
In closed circulation, can automatic identification and adapt to load variation, control can be continuously adjusted when velocity variations are larger, transmission
Steady impact resistance can preferably realize the flexible protective to hammer axis, greatly improve hammer axis service life, and explosion-proof performance is more preferable, effect
Rate increases, compact-sized, and failure rate is low, while eliminating the power such as motor, coupling device and retarder and drive apparatus,
Cost is greatly lowered.Therefore, it is more suitable for being mounted directly use on crusher than traditional driving device in all respects.
Summary of the invention
The object of the present invention is to provide the hammer mills that kind of hydraulic motor directly drives, including hammer mill, hydraulic motor
And coupling assembly.
The purpose of the present invention is achieved through the following technical solution:
The invention discloses a kind of hammer mills that hydraulic motor directly drives, including hammer mill, hydraulic motor and shaft coupling
The hammer axis of component, hammer mill is coupled with the output shaft of hydraulic motor by coupling assembly flat key or spline, and electricity is saved
Multiple large-sized powers such as motivation, coupling device and retarder and drive apparatus.Hammer mill side is welded with gusset piece, hydraulic horse
It is fixed on hammer mill up to positioning and being connected by bolts by seam allowance with gusset piece.The working media of hydraulic motor is
Oil, hydraulic system are closed circuit.
Beneficial effects of the present invention are mainly manifested in:
The present invention directly drives hammer mill using hydraulic motor, makes the working media be by the closed circuit of hydraulic system
Closed circulation in system, can automatic identification and adapt to load variation, control can be continuously adjusted when velocity variations are larger, biography
Steady impact resistance to be moved, can preferably realize the flexible protective to hammer axis, greatly improves hammer axis service life, explosion-proof performance is more preferable,
Compact-sized, efficiency increases, and failure rate is low, while eliminating the power such as motor, coupling device and retarder and transmission is set
It is standby, considerably reduce cost.
Detailed description of the invention:
Attached drawing of the invention is constituted for providing a further understanding of the present invention, illustrative embodiments and their description of the invention
It is used to explain the present invention, does not constitute improper limitations of the present invention.In the accompanying drawings:
Fig. 1 is a kind of hammer mill structure chart that hydraulic motor directly drives
In figure: 1. gusset piece of A. hammer mill B. coupling assembly C. hydraulic motor
Embodiment:
With reference to the attached drawing in the embodiment of the present invention, technical solution in the embodiment of the present invention completely, clearly retouch
It states, it is clear that the described embodiment is only a part of the embodiment of the present invention, and not all.
A kind of hammer mill that hydraulic motor directly drives, including A. hammer mill, C. hydraulic motor and B. shaft coupling group
Part, A. hammer of hammer crusher axis are coupled with C. hydraulic motor output shaft by B. coupling assembly flat key or spline, and electricity is saved
Multiple large-sized powers such as motivation, coupling device and retarder and drive apparatus.A. hammer mill side is welded with 1. gusset pieces, C.
Hydraulic motor and 1. gusset pieces, which are positioned and are connected by bolts by seam allowance, to be fixed on crusher.C. the work of hydraulic motor is situated between
Matter is oil, and hydraulic system is closed circuit.
It should be appreciated that being above schematical by the detailed description that preferred embodiment carries out technical solution of the present invention
And not restrictive.Those skilled in the art can be to recorded in embodiment on the basis of reading description of the invention
Technical solution modify or equivalent replacement of some of the technical features, and these are modified or replaceed, not
The essence of corresponding technical solution is set to be detached from the spirit and scope of technical solution of the embodiment of the present invention.
