Description

A kind of plastic cement compound blender

Technical field

This utility model relates to road and bridge construction mechanical field, more specifically, it relates to a kind of plastic cement compound blender。

Background technology

Plastic cement compound is general adopted most common ground surface material in athletic ground, in order to test plastic cement, whether to meet road surfacing up to standard, then it is accomplished by plastic cement is mixed and stirred in advance test, plastic cement blender is exactly one of most important equipment, usual plastic cement compound is as a kind of composite, being formed by combining by plastic cement, coarse aggregate, fine aggregate, breeze, wherein mixing and stirring of compound is a considerable link, the whether uniform quality directly affecting compound mixed and stirred；Existing plastic cement blender often cannot ensure that the unexpected injury, particularly motor of operator are when starting, and the stirring paddle meeting high speed rotating being exposed to, if people's hypotelorism easily causes the injury of health, it is impossible to effectively play the strick precaution of production safety。

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is in that to provide a kind of plastic cement compound blender, it is possible to resolve the problem that equipment operationally cannot ensure production safety。

For achieving the above object, this utility model provides following technical scheme:

A kind of plastic cement compound blender, including the blender in frame and frame, described blender is internally provided with protection circuit, and described protection circuit includes,

Induction module, for sensing the output detections signal of biological thermal source；

Alarm modules, receives and responds to the detection signal of induction module output, exports alarm signal；

Drive module, receive and respond to the detection signal of induction module output, drive relay to start。

By adopting technique scheme, so that blender ensures safety in production in the running, when avoiding blender to be stirred, the health distance blender of human hand or people is crossed near and is damaged, protection circuit it is provided with in blender, induction module in protection circuit may be used for sensing foreign object and enters in blender, now induction module transmits induced signal to alarm modules, alarm modules receives and starts alarm, alarm modules is to driving module to continue transmission signal simultaneously, the drive source that module controls blender is driven to close, reach timely stopping, foreign object is avoided to enter inside blender, blender remains in operation the injury that foreign object is caused。

This utility model is further arranged to: described induction module includes,

Detection unit, the biological thermal source in the detection external world output detections signal；

Converting unit, is coupled to detection unit, exports after detection signal is carried out electricity opto-electronic conversion。

This utility model is further arranged to: described detection unit includes infrared sensor, for biological thermal source is carried out sensing output detections signal。

By taking technique scheme, infrared sensor T is mainly used in the infrared detection to blender foreign object, when foreign object distance blender hypotelorism being detected, infrared sensor T produces and transmits signal, now photoelectrical coupler T1 diode one end receives signal and produces light source, generation due to optical signal, sensing element in photoelectrical coupler T1 makes luminous energy be converted into electric energy, photoelectrical coupler T1 produces current direction relay and buzzer T2, buzzer T2 starts to report to the police through current lead-through, and relay conducting provides loop current for driving module。

By taking technique scheme, signal is changed by the Main Function of converting unit exactly accordingly, so after detection unit passes output detections signal, being converted unit and received, now carry out conversion then through photoelectrical coupler and be changed to detection signal。

This utility model is further arranged to: described alarm modules includes,

Buzzer, is coupled to converting unit, response detection signal jingle bell alarm。

By taking technique scheme, when the buzzer in alarm modules and relay are simultaneously received after the control signal of converting unit, relay starts simultaneously at work with buzzer because of in parallel, and relay drive motor rotates, and buzzer sends jingle bell alarm。

This utility model is further arranged to: described infrared sensor also peripheral hardware is connected to knife switch, and described knife switch one end and infrared sensor couple, and the other end couples ground connection。

By adopting technique scheme, when carrying out reporting to the police without when protecting by blender, it is possible to prevent the startup of alarm modules, after disconnecting switchblade knife K, separated due to infrared sensor T and primary nodal point, protection circuit cannot be provided signal by infrared sensor T, and induction module cannot receive signal and start, thus alarm modules cannot be run, it is to avoid need not time buzzer T2 warning interference。

Compared to prior art, this utility model has equipment and operationally ensures production safety advantage。

Detailed description of the invention

With reference to accompanying drawing, embodiment of the present utility model is described further。

With reference to Fig. 1, so that blender 111 ensures safety in production in the running, when avoiding blender 111 to be stirred, the health distance blender 111 of human hand or people is crossed near and is damaged, it is provided with protection circuit in blender 111, induction module 100 in protection circuit may be used for sensing foreign object and enters in blender 111, now induction module 100 transmits induced signal to alarm modules 200, alarm modules 200 receives and starts alarm, alarm modules 200 is to driving module 300 to continue transmission signal simultaneously, the drive source that module 300 controls blender 111 is driven to close, reach timely stopping, foreign object is avoided to enter blender 111 internal, blender 111 remains in operation the injury that foreign object is caused。

With reference to Fig. 2, infrared sensor 112 is mainly used in the infrared detection to blender 111 foreign object, when foreign object distance blender 111 hypotelorism being detected, infrared sensor 112T produces and transmits signal, now photoelectrical coupler 113 diode one end receives signal and produces light source, generation due to optical signal, sensing element in photoelectrical coupler T113T1 makes luminous energy be converted into electric energy, photoelectrical coupler 113 produces current direction relay 119 and buzzer 115, buzzer 115 starts to report to the police through current lead-through, and relay T2119 conducting provides loop current for driving module 300。

With reference to On current after Fig. 3 and Fig. 4, relay T2119 reception signal, now alarm modules 200 is to driving module 300 to transmit electric current。When forming loop after driving module 300 to receive alarm modules 200 electric current and between power supply, now driving module 300 to start working, coil T3 operating drives blender 111 drive source to drive or stops。

When carrying out reporting to the police without when protecting by blender 111, it is possible to prevent the startup of alarm modules 200, after disconnecting switchblade knife 114, separated due to infrared sensor 112 and primary nodal point, protection circuit cannot be provided signal by infrared sensor 112, induction module 100 cannot receive signal and start, thus alarm modules 200 cannot be run, it is to avoid need not time buzzer 115 warning interference。

The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model。It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model。
