Abstract
The utility model relates to a sand blasting machine field, concretely relates to sand blasting machine sand bucket alarm device. It includes sand bucket, photoelectric switch, controller, and photoelectric switch includes transmitter and receiver, and the transmitter is equipped with to the inside lower extreme position one side that is close to of sand bucket, and the opposite side corresponds the transmitter and is equipped with the receiver, and transmitter and receiver passing signal line be connection director respectively, and the controller passes through the wire and connects motor, oscillator, is equipped with the buzzer above the controller. The advantage is that the design is simple, and convenient to use utilizes correlation type photoelectric switch to detect diamond dust quantity, and sand bucket no. 1 is less than photoelectric switch detection position, just immediately motor and oscillator bring to rest, safe and reliable, protective apparatus, reduction operation.
Description
Technical field
The utility model relates to sand-blasting machine field, is specifically related to a kind of sand-blasting machine sand bucket warning device.
Background technology
In use, the diamond dust sand amount in sand bucket is limited to sand-blasting machine, has used up and has not also known, motor, oscillator all in operation, need personnel to cut off one by one, lose time, and equipment idle running also has infringement.
Summary of the invention
In order to solve the problem, the utility model proposes a kind of sand-blasting machine sand bucket warning device, simplicity of design, easy to use, utilize correlation type optoelectronic switch to detect diamond dust quantity, easily control.
In order to reach foregoing invention object, the utility model proposes following technical scheme:
Sand-blasting machine sand bucket warning device, it comprises sand bucket, optoelectronic switch, controller, optoelectronic switch comprises transmitter and receiver, sand bucket is inner is equipped with transmitter near lower end position side, the corresponding transmitter of opposite side is equipped with receiver, transmitter and receiver are by holding wire connection control device respectively, and controller connects motor, oscillator by wire, above controller, buzzer is housed.
In the main circuit of described sand-blasting machine sand bucket warning device, normally closed remote control switch is housed, motor, motor two ends oscillator in parallel, main circuit is parallel with warning circuit, warning circuit is equipped with and often drives remote control switch and buzzer, main circuit is also parallel with 24V apparatus for converting DC power, transmitter and the receiver that optoelectronic switch is housed in parallel on 24V apparatus for converting DC power, transmitter comprises resistance and light emitting diode, resistance is together with light emitting diode series connection, receiver comprises resistance, amplifier and control coil, resistance is together with amplifier series connection, control coil is connected in parallel on resistance outer end.
The utility model has the advantages that simplicity of design, easy to use, utilize correlation type optoelectronic switch to detect diamond dust quantity, sand bucket one detects position lower than optoelectronic switch, just immediately motor and oscillator out of service, safe and reliable, proterctive equipment, reduces operation.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is circuit diagram of the present utility model.
Detailed description of the invention
In order to further illustrate the utility model, introduce below in conjunction with Figure of description:
With reference to accompanying drawing, sand-blasting machine sand bucket warning device, it comprises sand bucket 1, optoelectronic switch, controller 2, optoelectronic switch comprises transmitter 3 and receiver 4, sand bucket 1 is inner is equipped with transmitter 3 near lower end position side, and the corresponding transmitter 3 of opposite side is equipped with receiver 4, and transmitter 3 and receiver 4 are by holding wire connection control device 2 respectively, controller 2 connects motor M, oscillator 5 by wire, and controller 2 is equipped with buzzer above.
In the main circuit of described sand-blasting machine sand bucket warning device, normally closed remote control switch J1 is housed, motor M, motor M two ends oscillator 5 in parallel, main circuit is parallel with warning circuit, warning circuit is equipped with and often drives remote control switch J2 and buzzer 6, main circuit is also parallel with 24V apparatus for converting DC power 7, transmitter 3 and the receiver 4 that optoelectronic switch is housed in parallel on 24V apparatus for converting DC power 7, transmitter 3 comprises resistance and light emitting diode 8, together with resistance is connected with light emitting diode 8, receiver 4 comprises resistance, amplifier 9 and control coil J, together with resistance is connected with amplifier 9, control coil J is connected in parallel on resistance outer end.
When the utility model uses, when diamond dust in sand bucket is higher than optoelectronic switch position, diamond dust blocks the light that transmitter sends, receiver does not receive optical signal, whole optoelectronic switch is just in closed condition, control coil J is just in release conditions without electricity, and in a state of nature, motor and oscillator normally run normally closed remote control switch J1 and Chang Kai remote control switch J2; Once in sand bucket diamond dust lower than optoelectronic switch position, receiver receives the optical signal sent of transmitter, optoelectronic switch is just in open mode, control coil J obtains electric, control coil J closes, then normally closed remote control switch J1 opens and causes motor and oscillator dead electricity, often opens that remote control switch J2 is closed makes buzzer warning.
