Cost.
The guide groove 101l and gib block 101c is gap-matched, and the work of guide and limit is played to weight block 101d
With effectivelying prevent weight block 101d, there is a phenomenon where deviations during the motion, while weight block 101d can be balanced and be forced in
Air bag 101i is more advantageous to air bag 101i and inflates outward.
The bore of the venthole 101m is much smaller than the bore of sand, and two neighboring venthole 101m is in the laying that is staggered,
It effectively prevent sand to enter inside air-dispersing rramming block 101g by venthole 101m, is also avoided that venthole 101m is blocked,
More advantageous air-flow is uniformly spread, so that sand is maintained drying.
Spacing between the sanding particle head 101n and sanding particle head 101n is much larger than the bore of maximum sand, effectively
Sand is prevented to be stuck between sanding particle head 101n and sanding particle head 101n, sand of the more advantageous sanding particle head 101n to agglomeration
Son is broken up.
The setting of the sponge buffer stopper 101b plays the role of buffering to weight block 101d, can effectively prevent weight block
With concave mounting head 101a rigid collision occurs for 101d due to whereabouts is overweight, avoids weight block 101d impaired.
The working principle of the invention: sand is poured into from feed hopper 4 and is tumbled in drum sieve 2, and drum sieve 2 is rotated to sand
Son is screened, and when sieving sand, knocking device 3 beats drum sieve 2, effectively prevent 2 blockage phenomenon of drum sieve, cylinder
Sieve 2 drives driven wheel 12 to rotate rotation by transmission belt 11, so that shaft 13 drives sanding while linkage
The sand of 10 pairs of agglomerations of mechanism carries out breaing up operation, is more advantageous to the screening of sand, effectively prevent being greater than clearance hole because of agglomeration sand
And be discharged, sieve sand efficiency is further improved, avoids qualified sand from being screened, specially mounting disc 100 is with shaft 13
Dynamic and sanding group 101 is rotated, sanding group 101 stir to sand scattered, while sanding cylinder 101j and air-dispersing rramming when rotating
Block 101g also generates centrifugal force to sand, the sand of agglomeration throwing out ruthlessly can be acted on drum sieve 2, thus the sand of agglomeration
Son is easier to scatter, and the sanding particle head 101n on sand cylinder 101j and air-dispersing rramming block 101g can more rub with sand
It wipes, while sand can also be effectively prevent to be stuck between sanding particle head 101n and sanding particle head 101n, more advantageous sanding
Grain head 101n breaks up the sand of agglomeration, when air-dispersing rramming block 101g rotates to be vertically drum sieve 2 by horizontality
When inner bottom surface state, weight block 101d is due to self gravity and under the effect of the guide and limit of guide groove 101l and gib block 101c
And to air bag 101i movement and gradually to air bag 101i pressure, so that inner spring 101h is compressed by original state, so that air bag 101 is logical
It crosses outlet nozzle 101f to inflate into air-dispersing rramming block 101g, uniform guide functions of the air-flow in metal mesh 101e and venthole 101m
Sand is acted on down, while sanding group 101 also has distinguished and admirable generation in rotary course, so that sand is maintained drying.
In conclusion the technological progress that the present invention obtains compared with the prior art is: the drum type brake sand sieving machine is built-in with sanding
Device is arranged, using drum sieve as power source, in drum sieve to sand by the combination of sanding mechanism, transmission belt, driven wheel, shaft
Sand lump is broken up by sanding mechanism while son is screened, the sand quilt for effectively avoiding the ratio screen holes in sand lump small
It screens out, helps to improve screening effect, while sand lump can be effectively prevent to block more screen holes, be conducive to improve screening
Efficiency reduces screening time, in addition combination setting of the sanding group by components such as sanding cylinder, weight block, air bag, inner springs, benefit
It is miscarried and is given birth in rotary course apoplexy with the gravity and spring of weight block, the characteristic of air bag and sanding group, sand lump can included
There is the sand of moisture to blow, so that sand is maintained drying, avoids occur agglomerating again when sand is accumulated after screening from showing
As.
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art,
It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is carried out etc.
With replacement, all within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in this
