Description
Technical field
The utility model belongs to mechanical equipment technical field, is specifically related to a kind of roller sand making grating machine.
Background technology
Roller sand making machine is widely used in the ore of below the industrial department medium hardness such as sand processed, ore dressing, cement, metallurgy, chemical industry, building materials and rock broken and in small, broken bits, the bearing block that existing roller sand making grating machine adopts is the formula of dividing right and left, and isolated operation, cannot ensure that rotor is parallel, product grain type can be caused single, and pair roller foot wheel abrasion is uneven, thus reduce service life; In addition, often motor cabinet adopts fixed, operationally produces side-to-side vibrations because of acting force of the spring like this to running roller, and when vibrating, belt easily drops, and produces stretching action, belt rapid wear during tensioner to belt; On the other hand, rotor adopts certain one dynamic form, and when fragmentation, discharging opening size is changing always, and the product size that such fragmentation goes out is uneven.
Utility model content
The purpose of this utility model is to provide a kind of roller sand making grating machine, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of roller sand making grating machine, comprise body and gantry base, described gantry base is provided with firm banking and mobile base, firm banking described in it is provided with running roller and the feeding mouth that is arranged on running roller top, described dynamical system is provided with to running roller side, opposite side was provided with iron protective device, describedly be fixed on power transmission shaft to running roller by large round nut, described large platen is also provided with to running roller inside, seamless pipe and little platen, described large platen and described little platen are separately positioned on the both sides of seamless pipe, the side of described power transmission shaft is provided with shaft coupling and bearing holder device, described bearing holder device is arranged on the inner side of shaft coupling, described seamless pipe is fixed on power transmission shaft by holding out against screw.
Preferably, described dynamical system comprises motor and decelerator, fixed rotor and belt, and described motor and described fixed rotor are that integral type is connected.
Preferably, described body both sides are provided with adjustment briquetting.
Technique effect of the present utility model and advantage: this roller sand making grating machine, comprise running roller, dynamical system, cross iron protective device, power transmission shaft, shaft coupling, bearing holder device and hold out against screw, due to rotor run-in synchronism when board works, make product grain type even, reduce back broken rate, enhance productivity, motor and rotor are that integral type is connected, reduce belt vibration, reduce wearing and tearing, rotor is set to fixed, without moving left and right during work, easily running roller is rotated and article are pulverized, ensure that the product produced is in the same size, improve the quality of products, when being mingled with the excessive object of hardness in charging, pass through telescopic spring, rotor spacing changes, increase rotor life cycle, and broken yield rate can reach about 70 percent, this roller sand making grating machine is reasonable in design, high degree improve broken yield rate.
