The output of the utility model the first drive unit is connected with the roll shaft of the first breaker roll by the first shaft coupling, and the output of the second described drive unit is connected with the roll shaft of the second breaker roll by the second shaft coupling.

As shown from the above technical solution; the utility model is by arranging first, second, third, fourth temperature sensor; can effectively to the operating temperature of four bearings, monitor; when the temperature of bearing surpasses setting value; temperature sensor can be given shutdown signal of master control power supply; now close first, second drive unit, play the effect of protection disintegrating machine.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described further:

A kind of bi-fluted roller type disintegrating machine as shown in Figure 1, comprise disintegrating machine body 1, in disintegrating machine body 1, be provided with the first breaker roll 2 and the second breaker roll 3 that parallel, wherein the first breaker roll 2 is respectively by first, the second bearing 21, 22 are fixed on disintegrating machine body 1, and the roll shaft of the first breaker roll 2 is connected with the first drive unit 41, the second breaker roll 3 is respectively by the 3rd, the 4th bearing 31, 32 are fixed on disintegrating machine body 1, and the roll shaft of the second breaker roll 3 is connected with the second drive unit 42, the roll shaft of the roll shaft of the first breaker roll 21 and the second breaker roll 3 is away from first, the second drive unit 41, one end of 42 is provided with intermeshing first, the second gear 5, 6, the first breaker roll 2 and the second breaker roll 3 locking phases are to rotation, and be equipped with crushing teeth on the first breaker roll 2 and the second breaker roll 3, on clutch shaft bearing 21 and the 3rd bearing 31, be respectively equipped with first, three-

temperature sensor

71, 73.

Preferably, on the second bearing 22 and the 4th bearing 32, be respectively equipped with the second, the 4th temperature sensor 72,74, be used for fixing like this on four bearings of the first breaker roll 2 and the second breaker roll 3 and be equipped with temperature sensor, better to the monitoring effect of bearing.When the temperature of bearing surpasses setting value (referring generally to over 75 ℃), temperature sensor can be given shutdown signal of master control power supply, now closes first, second drive unit, plays the effect of protection disintegrating machine.
