Mobile and support is broken the lump material of cutting, and himself is same easily occurs overload deformation, and block
The cutting that material is crushed cutting by crushing toothed roller is impacted, and under this impact force action, causes lump material
Moment of being broken produces and unordered splash and roll；For frame in said structure to guide plate, and then pass through
The support of lump material is arranged by guide plate, due to the factor such as weight of lump material so that guide plate and frame
Between cannot obtain stable use state by arranging the Structure deformation of roller, this comes from lump material
Easily damaged to the axle or bearing that make roller and then needs are frequently changed by weight and the impact dropped, and therefore lead
Between plate and frame generally by sliding contact to realize the frame support to guide plate, and be also derived from guide plate
Load to lump material so that the sliding friction between guide plate and the frame of movement easily causes guide plate and machine
The Fast Wearing of frame and bigger operating noise；In running, owing to falling within the block on conveyer device
Shape material has ponderable randomness and uncertainty, the therefore poor stability of course of conveying；Same because falling
Lump material on conveyer device has randomness and uncertainty, this tooth that makes to be broken the most in the same time
Increasing and decreasing randomly occurs in the lump material that roller carries out crushing；It is drawn through spiral shell between above-mentioned chain and scraper plate
Stricture of vagina connector level is connected, and this makes threaded connector, when by bigger load, the phenomenons such as dropout easily occur.
Above structure arranges and makes that monodentate kibbler roll operation stability is low, poor durability, simultaneously crushing efficiency
The operation stability of above-mentioned mono-roller type disintegrating machine of the prior art is low, poor durability and crushing efficiency
The design defect such as low becomes those skilled in the art and is presently required and solves the technical problem that.

Detailed description of the invention
The core of the present invention is to provide a kind of feeding crushing equipment, will be significantly improved by the application of the present invention
Operation stability, ruggedness and crushing efficiency.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the present invention, and
It is not all, of embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art are not doing
Go out the every other embodiment obtained under creative work premise, broadly fall into the scope of protection of the invention.
Refer to Fig. 1 to Fig. 5, each specific embodiment will be described according to Fig. 1 to Fig. 5 below.
Include rotating and border is provided with for lump material carries out the feeding crushing equipment of broken cutting
The breaker roll 1 of crushing teeth 11, for support the scraper plate 2 that carries lump material, the top surface 21 of scraper plate 2
Having angle with horizontal plane, the span basis of design of angle includes the average thickness of lump material, breaks
The structure of broken roller 1 and location parameter and the finished breaking granularity of lump material, the direction of steeving of angle is with broken
The rotation direction of tooth 11 is consistent.Carry lump material at scraper plate 2, and then lump material is broken cutting process
In, power, by the broken cutting force of crushing teeth 11, is transferred to scraper plate 2 by lump material, due to scraper plate 2
Top surface 21 has that set according to above-mentioned parameter with horizontal plane angle, and angle steeve direction with
The rotation direction of crushing teeth 11 is unanimously arranged, and which ensure that top surface 21 is cut towards the broken of crushing teeth 11
Cut force direction, therefore the direction of the power that scraper plate 2 top surface 21 is transmitted is basic and top surface 21 in
Vertical and do not have excessive angle, this makes scraper plate 2 can provide the support stronger to lump material, from
Body will not be because of the extruding force of excessive incline direction that is subject to and the deformation that deflects, meanwhile, to lump material
Support in basic front makes lump material can preferably be crushed cutting effect.Such as, originally give
The average diameter of lump material can be crushed to 100mm by 600mm by material disintegrating apparatus, therein initially
What particle mean size 600mm was angle arranges one of reference data.
In prior art, do not set the top surface of scraper plate according to lump material thickness and the structure of breaker roll
The parameters such as size set angle of inclination, crush lump material under crushing teeth and scraper plate act on jointly
During cutting, it is impossible to reaching upper and lower forward and coordinate generation squeezing effect, this makes scraper plate by lump material
Extruded by the bigger inclination of breaker roll, cause scraper plate to be easily generated torsional deformation and even damage, the most unfavorable
In expeditiously lump material being carried out broken cutting.Thus, compared to prior art, the present invention's should
With significantly improving operation stability, ruggedness and crushing efficiency.
In another specific embodiment, the top surface 21 arranging scraper plate 2 is perpendicular to crushing teeth 11 and block
The estimating the tangential of initial contact point and can be vertically subject to by lump material realizing scraper plate 2 of material
The extruding of crushing teeth 11, the position basis of design estimating initial contact point includes the average thickness of lump material
Structure and location parameter with breaker roll 11.Arranged by above structure, when scraping in feeding crushing equipment
Plate 2 support lump material and is transported between crushing teeth 11 and lump material the initial contact preset
During point, lump material contacts with crushing teeth 11 and the tooth 11 that is broken crushes cutting, according to physical principle, block
Shape material is being broken in cutting process by overall structure, and its structural damage process is necessarily initial broken
Need during broken cutting to apply maximum broken cutting force, i.e. crushing teeth 11 at initial contact broken cutting cube
Moment during shape material is maximum, and this position is in feeding crushing equipment the initial contact point estimated, due to
The physical dimension of lump material has not unicity, and the initial contact point therefore arranged can be according to above-mentioned each ginseng
Number synthesis calculates and then estimates out this initial contact point.In initial contact point position, lump material is with broken
The produced active force of extruding between tooth 11 is transferred to be perpendicular to the top of the scraper plate 2 of this force direction
Surface 21, then coordinate the squeezing effect position to lump material between the top surface 21 of scraper plate 2 and crushing teeth 11
On same linear function direction, this makes scraper plate 2 can keep the stability of strutting system of self, and to bulk
The broken cutting of material reaches optimum efficiency, avoids splashing of broken lump material simultaneously.
Scraper plate top surface and crushing teeth are not set between the initial contact point to lump material by prior art
Put relevant vertical positional relationship, therefore, jointly act on crushing teeth at scraper plate and lump material is broken
In broken cutting process, the extruding of the crushing teeth suffered by scraper plate easily makes crushing shell produce torsional deformation, simultaneously
Lump material is broken the poor effect of cutting, and the bulk easily crushed because the existence of extruding angle
Splashing of material.Thus, ining contrast to prior art, the feeding crushing equipment that the present invention provides will significantly carry
High operation stability, the ruggedness of equipment and the crushing efficiency to lump material.
At another about in the specific embodiment of feeding crushing equipment, on the basis of above-mentioned specific embodiment
On, also include the insertion plate door device 3 for the lump material carried being carried out limit for height and limitation, along scraper plate
The insertion plate door device 3 that the top of 2 and both sides are arranged constitutes closed loop with scraper plate 2 on its moving direction cross section
Profile.Height and the limiting structure of width that scraper plate 2 and slotting door apparatus 3 collectively constitute make scraper plate 2 carry
After lump material moves through slotting door apparatus 3, the lump material of both sides and short transverse redundancy is plugged in door-plate
Device 3 intercepts and stops, and the intercepted redundancy lump material landing stopped to follow-up follow-up scraper plate 2 and then
Continuing across slotting door apparatus 3, thus, the lump material after slotting door apparatus 3 is crossed in the warp let-off has unified
Height and width are piled up, and this makes the volume and weight of the lump material persistently carried be guaranteed, with
Time, contact with breaker roll 1 at lump material, be broken when tooth 11 is broken to be cut and there is unified dimensions,
The broken cutting output torque that this one side makes breaker roll 1 is more stable, on the other hand more ensure that broken
The positional accuracy of the initial contact point of tooth 11 and lump material.Therefore, the setting inserting door apparatus 3 enters one
Step improves stability and the crushing efficiency that equipment runs.
For the scraper plate 2 in above-mentioned specific embodiment, scraper plate 2 is set to the wedge shape that cross section is hollow structure
Scraper plate 2.Owing to it needs support lump material and withstands shocks, therefore it is set to the wedge shape structure of hollow structure
Make the effect enabling to play gusset each other between each several part of scraper plate 2, improve the carrying energy that support supports
Power, avoids simultaneously and is set to the weight increasing that more thick and heavy solid construction is brought by increasing bearing capacity
The drawback added so that conveying power draw, as much as possible for the conveying to lump material, it reduces negative
Carry, add the stability of operation.
On the basis of above-mentioned specific embodiment, it is also possible to be provided for keeping broken cutting stability in real time
Load limiting type of constant filling fluid coupling, it is broken with drive breaker roll 1 that load limiting type of constant filling fluid coupling is installed on breaker roll 1
To adapt to the moment variations that the real-time quantitative change of lump material causes between broken roll driving apparatus.Due to block
The size of material has uncertainty, is therefore delivered to the lump material of breaker roll 1 by scraper plate 2 in each moment
There is the randomness of size and quality, which results in institute when breaker roll 1 carries out crushing cutting to lump material defeated
The moment gone out is real-time change, and if at a time assemble to breaker roll 1 position lump material relatively
Many, the output torque of breaker roll 1 beyond rated range, " suppressing car " i.e. commonly referred to, then easily causes
The damage of breaker roll driving means, by the setting of load limiting type of constant filling fluid coupling in this specific embodiment, just
Can be by leading between breaker roll driving means and breaker roll 1 in the case of breaker roll 1 output torque transfinites
The leader tape relation of being dynamically connected separates, and protects breaker roll driving means with this.Presented herein
Breaker roll driving means is usually motor.
On the basis of above-mentioned specific embodiment, it is also possible to monitoring system is set and for driving scraper plate 2 to move
Frequency conversion motor, monitoring system is connected with load limiting type of constant filling fluid coupling with can monitoring coupling information, monitoring
System can be connected with frequency conversion motor to speed governing.In the arranging of this specific embodiment, when moment-limited hydraulic is even
When clutch carries out corresponding coupling change with the change of output torque, its coupling information system of being monitored is supervised
Control, and have this coupling information, monitoring system carries out speed governing to frequency conversion motor.Coupling information discloses brokenly
The broken real-time moment of roller 1 exports, the big or little block illustrating to be delivered to breaker roll 1 position of moment output
Material number, therefore, monitoring system information accordingly controls the rotation speed change of frequency conversion motor, and then have adjusted
Scraper plate 2 carries the speed of lump material, and this had both avoided scraper plate 2 and the conveying of more lump material has been accumulated to brokenly
The state of broken roller 1, it also avoid crushing few, and the state that crushing efficiency is low thus ensure that broken effect
Rate.Meanwhile, which further improves the protective effect to breaker roll 1.
In another specific embodiment, feeding crushing equipment also includes scraping in the frame 4 of support scraper plate 2
The passive slide rail of plate 2.Owing to scraper plate 2 moves conveying when support lump material,
Therefore bigger frictional force is produced between frame 4 and the scraper plate 2 of support scraper plate 2, big between frame 4 and scraper plate 2
The friction of area will make the serious wear of frame 4 and scraper plate 2, and this is unfavorable for the operation steady in a long-term of equipment,
Arranging slide rail in frame 4 can make scraper plate 2 reduce with the contact area of frame 4, and this makes the long-term of equipment
Stability in use increases.For slide rail set in frame 4, it can be set for engineering plastics material
Slide rail, This further reduces friction.It is, for example possible to use the slide rail of nylon material.
In another specific embodiment, for being directly connected and draw the chain 5 that scraper plate 2 moves with scraper plate 2,
Chain 5 arranges location-plate 51, accordingly, scraper plate 2 is provided with locating slot, makes chain 5 and scrape
Plate 2 is connected up and down by the grafting between location-plate 51 and locating slot.Due to location-plate 51 and locating slot
Being matched with face by face and contact, the ability of power conduction is strong.Prior art is threaded connection part will scrape
Plate is connected in horizontal plane with chain, and in power conductive process, because the factor such as rocking, screw buckle is easily sent out
The phenomenons such as raw dropout.Therefore, ining contrast to prior art, this structure makes the operation stability of equipment obtain
Further, by chain 5 hook tensioner 6 with regulate chain 5 rate of tension, due to scraper plate 2
