Abstract
The utility model relates to a grid sieve, particularly relates to an inlet grid sieve of a crusher, and belongs to the technical field of mining equipment. The inlet grid sieve comprises a grid body and square sieve pores. The square sieve pores comprise grid bars which longitudinally and transversely intersect with one another, the grid body comprises a front grid and a rear grid, a rear frame of the front grid is connected with a front frame of the rear grid by an elastic pad, the front grid and the rear grid are fixedly locked by bolt pairs which are arranged below a sieve surface, and a resin abrasion-resistant layer is coated on the upper surface of the front grid. The inlet grid sieve has the advantages that the inlet grid sieve is convenient to maintain and difficult to block, the material utilization rate of the grid sieve can be increased, the service life of the inlet grid sieve can be prolonged, and the production cost can be reduced.
Description
Technical field
The utility model relates to a kind of Grid screen, and particularly a kind of disintegrating machine entry grates sieve, belongs to mining equipment technical field.
Background technology
In mining process, the ore of exploiting out needs advanced row filter before carrying out fragmentation entering disintegrating machine tiger's jaw, to avoid excessive ore to cause damage to disintegrating machine.Grid screen, in the process of vibration screening, due to the factor such as impact, gravity of ore, can cause the wear-out failure of Grid screen.Especially the front portion of Grid screen, be not only subject to the impact that ore falls, and ore weight is larger, weares and teares more serious, causes whole Grid screen to be scrapped.
Utility model content
According to above the deficiencies in the prior art, technical problem to be solved in the utility model is: a kind of disintegrating machine entry grates sieve is provided, and easy to maintenance, improve Grid screen stock utilization, increase the service life, be difficult for stopping up, reduce production costs.
A kind of disintegrating machine entry grates sieve described in the utility model, the square sieve aperture that comprises grid body and formed by crisscross grizzly bar, grid body is made up of front grid, rear grid, the rear frame of front grid is connected with the front bezel of rear grid by bullet pad, both are by being arranged on the bolt pair fixing and locking of compass screen surface below, front grid upper surface coated with resins wearing layer.
By grid body being divided into front grid, rear grid, damaged by the factors such as ore impact very fast, after current grid damages, changed, rear grid damages slower, and service time is longer, has therefore improved Grid screen stock utilization, greatly extend service life, reduced maintenance cost.By bolt pair fixing and locking, front grid and rear grid are connected firmly, prevent from becoming flexible, front grid keeps good use state, has reduced the probability of stopping up.Front grid upper surface coated with resins wearing layer, slows down the dynamics of knowing clearly and impacting on the one hand, has strengthened on the other hand anti-wear performance.
Described grizzly bar cross section is inverted trapezoidal, and corresponding screen size increases downwards gradually along compass screen surface, and it is trapezoidal that sieve aperture is, and along with the whereabouts of ore, screen size increases gradually, makes ore be difficult for being blocked in sieve aperture, has reduced obstruction probability.
Described front bezel, rear frame are equipped with downward flanging, and bolt pair is fixed on this flanging.
Described bolt pair two ends length dimension is less than the width dimensions of front grid and rear grid junction, and bolt pair is hidden in below, junction, while avoiding ore to fall, interferes.
Described resin wearing layer is 2～3mm.
Described front grid accounts for 1/4～1/3 of whole grid body.
When ore is fallen compass screen surface, fall to producing impact force action at front grid surface, under resin wearing layer buffering, reduced the destruction of impulsive force to front grid, ore screens with the vibration of compass screen surface subsequently, and the ore filtering out falls in disintegrating machine tiger's jaw.When current grid breakage is more serious, bolt pair is pulled down, the front grid more renewing, rear grid can continue to use, and the utilization rate that has extended material reduces maintenance cost.
Compared with prior art, the beneficial effect the utlity model has is:
This disintegrating machine entry grates is sieved by front grid, rear grid are set, and has improved Grid screen stock utilization, has greatly extended service life, reduces maintenance cost; Front grid upper surface coated with resins wearing layer, slows down the dynamics of knowing clearly and impacting on the one hand, has strengthened on the other hand anti-wear performance; It is trapezoidal that sieve aperture is, and along with the whereabouts of ore, screen size increases gradually, makes ore be difficult for being blocked in sieve aperture, reduced obstruction probability.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Fig. 1～2, this disintegrating machine entry grates sieve comprises grid body, grid body is made up of frame and grizzly bar 6, and crisscross grizzly bar 6 forms square sieve aperture 7, and grizzly bar 6 cross sections are inverted trapezoidal, corresponding sieve aperture 7 sizes increase downwards gradually along compass screen surface, sieve aperture 7 is trapezoidal, and along with the whereabouts of ore, sieve aperture 7 sizes increase gradually, make ore be difficult for being blocked in sieve aperture 7, reduced obstruction probability.Grid body is made up of front grid 1, rear grid 5, and wherein, front grid 1 accounts for 1/4～1/3 of whole grid body.The rear frame 2 of front grid 1 is connected with the front bezel 4 of rear grid 5 by bullet pad 3, front bezel 4, rear frame 2 are equipped with downward flanging, front grid 1, rear grid 5 are by being arranged on bolt pair 9 fixing and lockings of compass screen surface below, bolt pair 9 two ends length dimensions are less than the width dimensions of front grid 1 and rear grid 5 junctions, bolt pair 9 is hidden in below, junction, while avoiding ore to fall, interferes.Front grid 1 upper surface coated with resins wearing layer 8, resin wearing layer 8 is 2～3mm.
The course of work:
When ore is fallen compass screen surface, fall to producing impact force action on front grid 1 surface, under resin wearing layer 8 bufferings, reduced the destruction of impulsive force to front grid 1, ore screens with the vibration of compass screen surface subsequently, and the ore filtering out falls in disintegrating machine tiger's jaw.1 breakage of current grid when more serious, is pulled down bolt pair 9, the front grid 1 more renewing, and rear grid 5 can continue to use, and the utilization rate that has extended material reduces maintenance cost.
