Abstract
The utility model discloses a material bed detection arrangement of centrifuge, mainly comprising a detection plate arranged in a rotating drum of the centrifuge. The detection plate is connected with a transmission shaft. The transmission shaft is movably arranged on a shaft base. The centrifuge is also provided with an angle detector which can detect the rotation angle of the transmission shaft. When the material bed detection arrangement is used and when the material in the rotating drum surpasses the set value, the material can impel the detection plate to rotate and the detection plate can drive the transmission shaft to rotate an angle. Thus, the angle detector can detect the variation of the angle and can transmit a control signal to cause the feeding device to stop feeding so as to ensure the rotating drum not to operate in overloading state and ensure the normal operation of the centrifuge.

Embodiment
Below in conjunction with the drawings and specific embodiments technical scheme described in the utility model and operation principle thereof and advantage are further described.
As shown in Figure 1, be an embodiment of the present utility model, the structure of described bed of material sniffer is mainly: be provided with detecting plate 4 in the rotary drum 1 of centrifuge, as shown in Figure 3, detecting plate 4 is connected with power transmission shaft 6 by connecting plate 41, and as shown in Figure 1, power transmission shaft 6 is movably arranged in the axle bed 7; The same with the centrifuge of traditional structure, rotary drum 1 is arranged in the casing 3, is provided with cover 5 at the top of casing 3; On centrifuge, also be provided with the angle detection device that can detect power transmission shaft 6 anglecs of rotation.In the present embodiment, described angle detection device is: as shown in Figure 1 and Figure 2, be installed with drive sleeve 11 on power transmission shaft 6, be installed with mount pad 8 on axle bed 7, microswitch 9 is installed in the mount pad 8, and the contact 10 of microswitch 9 contacts with recess on the drive sleeve 11.In the present embodiment, on centrifuge, also be provided with thrust unit that can promote power transmission shaft 6 rotations and the resetting means that power transmission shaft 6 is resetted.As shown in Figure 1 and Figure 2, described thrust unit is: cylinder 13 is fixedly mounted in the mount pad 8, and the piston rod of cylinder 13 contacts with push arm 12 on the drive sleeve 11.As shown in Figure 2, described resetting means is: an end of back-moving spring 14 is connected with mount pad 8 upper branch arms 15, and the other end of back-moving spring 14 is connected with reset arm 16 on the drive sleeve 11.
The operation principle of the bed of material sniffer of said structure is: when the material 2 that enters into rotary drum 1 increases gradually, material 2 can be long-pending more thick more on the inwall of rotary drum 1, can configure the tilt angle of detecting plate 4 in advance earlier, the contact 10 of microswitch 9 is contacted with recess on the drive sleeve 11; After material 2 surpasses the scope of setting, material 2 will touch detecting plate 4, will promote detecting plate 4 rotations then, detecting plate 4 will drive angle of power transmission shaft 6 rotations, power transmission shaft 6 will drive drive sleeve 11 rotations, like this, recess on the drive sleeve 11 will break away from contact 10, that is to say, drive sleeve 11 can promote contact 10, make microswitch 9 send a signal of telecommunication, just can control feed arrangement after this signal controlled device receives and stop charging, thereby guarantee that rotary drum 1 can not work overloadingly, guarantee the operate as normal of whole centrifuge.
