Abstract
The utility model provides a coal level sensor and relates to the technical field of coal mining. A shell (1) is fixed through a screw; the upper part of a contact rod (3) is fixedly arranged inside the shell (1); a contact (2) is fixedly arranged at the lower part of the contact rod (3); a universal joint (4) is arranged inside the shell (1); the universal joint (4) is connected with the upper part of the contact rod (3); two wiring terminals (5) are arranged at two sides of the upper part of the shell (1); and a lifting lug (6) is arranged at the top of the shell (1) and a full-coal indication lamp (7) is arranged at the front part of the shell (1). When a machine head of a conveyor is buried, a cabin is full and a coal bucket is full, a power supply of the conveyor is automatically cut off so as to realize coal level protection; and materials can be prevented from being stacked and a blocking accident is prevented from being caused.
Description
Technical field:
The utility model relates to the coal-mining technique field, is specifically related to a kind of coal site sensor.
Background technology:
During Coal Production, in coal bunker, carry out coal piling by the conveyer belt carry coal, because all be that flow process all is full automatic, unmanned guard, in transportation, when coal bunker piled with, the situation that can cause coal bunker wharf explosion or chute to stop up lowered efficiency, and influence is produced.
The utility model content:
The purpose of the utility model provides a kind of coal site sensor, and it buries head, buys securities with all one's capital, when expiring coal hopper, cuts off the power supply of transporter automatically and realize the protection of coal position when transporter occurring, can prevent solid accumulation, and accident results in blockage.
In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises shell 1, contact 2, feeler lever 3, universal joint 4, binding post 5, hangers 6 and full coal pilot lamp 7; Shell 1 passes through screw retention; The top of feeler lever 3 is fixed on the inside of shell 1, and contact 2 is fixed on the bottom of feeler lever 3, and universal joint 4 is arranged on the inside of shell 1; Universal joint 4 is connected with the top of feeler lever 3; Two binding posts 5 are arranged on the both sides, top of shell 1, and hangers 6 is arranged on the top of shell 1, and full coal pilot lamp 7 is arranged on the front portion of shell 1.
The utility model has adopted cam structure and moment amplification principle, and is non-directional, is active in one's movements, can be in the place of dry coal, water coal and trickle operate as normal.
The utlity model has following beneficial effect: it buries head, buys securities with all one's capital, when expiring coal hopper, cuts off the power supply of transporter automatically and realize the protection of coal position when transporter occurring, can prevent solid accumulation, and accident results in blockage.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Referring to Fig. 1, this embodiment adopts following technical scheme:: it comprises shell 1, contact 2, feeler lever 3, universal joint 4, binding post 5, hangers 6 and full coal pilot lamp 7; Shell 1 passes through screw retention; The top of feeler lever 3 is fixed on the inside of shell 1, and contact 2 is fixed on the bottom of feeler lever 3, and universal joint 4 is arranged on the inside of shell 1; Universal joint 4 is connected with the top of feeler lever 3; Two binding posts 5 are arranged on the both sides, top of shell 1, and hangers 6 is arranged on the top of shell 1, and full coal pilot lamp 7 is arranged on the front portion of shell 1.
The utility model has adopted cam structure and moment amplification principle, and is non-directional, is active in one's movements, can be in the place of dry coal, water coal and trickle operate as normal.
This embodiment in use, when increase when passing sensor contact the coal position, when contact drives feeler lever deflection certain angle, universal contact conducting in it, full coal pilot lamp is bright, can cut off the power supply of transporter simultaneously automatically and realize the protection of coal position.
This embodiment is buried head, buys securities with all one's capital, when expiring coal hopper, is cut off the power supply of transporter automatically and realize the protection of coal position when transporter occurring, can prevent solid accumulation, and accident results in blockage.
