Detailed Description

In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1, this material level alarm device, including setting up trigger mechanism 1 in feed bin 4 and setting up in the outside suggestion unit 2 of being connected with trigger mechanism 1 in feed bin 4, still include photoelectric type rotational speed sensor 3, this trigger mechanism 1 includes pivot 12 and sets up the fan blade 11 in 12 one ends of pivot, and the 12 other ends of pivot stretch out feed bin 4 and set up photoelectric type rotational speed sensor 3, and this photoelectric type rotational speed sensor 3 is connected with suggestion unit 2 electricity. The utility model discloses in, feed bin 4 is for setting up according to bearing wall 5, and tip installation suggestion unit 2 after bearing wall 5 is worn out is followed to pivot 12, and of course, in some other embodiments, this feed bin 4 still can independently set up need not to depend on the bearing building.

The utility model discloses material level alarm device, the material of feed bin 4 is descending the in-process, and fan blade 11 becomes no rotating state that hinders by the quiescent condition that the material blockked, and trigger mechanism 1 work that comprises fan blade 11 and pivot 12 this moment, 3 collection of photoelectric type speed sensor and send electrical signal to suggestion unit 2 to make suggestion unit 2 carry out the suggestion of material level early warning. In a similar way, in the material rising process of the storage bin 4, the fan blade 11 is changed from a non-blocking rotation state into a static state blocked by the material, the trigger mechanism 1 composed of the fan blade 11 and the rotating shaft 12 works at the moment, and the photoelectric rotating speed sensor 3 collects and transmits a power signal to the prompting unit 2 so that the prompting unit 2 performs material level early warning prompting. The utility model discloses fan blade 11 and pivot 12 are simple mechanical structure, and photoelectric type speed sensor 3 sets up in the feed bin outside, receives the influence of dust less, and is not strict to use and installation environment requirement, and application scope is wider. Furthermore, the utility model discloses trigger mechanism 1 part is mechanical structure, and the cost is cheaper than current full photoelectricity formula structure.

Most material level measurement alarm device work is under serious dust environment, consequently considers prompt device's early warning suggestion effect, and this suggestion unit 2 includes base 22 and sets up the warning light 21 on base 22, and base 22 sub-unit connection has air supply 24, upper portion to be provided with and is used for dirt-proof first nozzle 25, and first nozzle 25 communicates with air supply 24 and just to with warning light 21. The air source 24 is communicated with the first nozzle 25, the air source 24 supplies air intermittently, and dust attached to the indicator light 21 is removed after the air is sprayed out from the first nozzle.

In order to further prevent dust from influencing the accuracy of the alarm device, a sealed space 23 is arranged in the base 22, one end of the rotating shaft 12 extends into the sealed space 23, a photoelectric rotating speed sensor 3 is arranged at the shaft end, and the photoelectric rotating speed sensor 3 is electrically connected with the prompting unit 2.
