Abstract
The utility model discloses a cylinder type feed bin unloading detection device, a cylinder type feed bin unloading detection device, including detecting head, cylinder, pneumatic system and electrical system, detect pretext probe and slide cartridge constitution, electrical system closes position switch before by pressure relay, cylinder, the electric cabinet is constituteed, its characterized in that: the plunger type sliding pair is formed by probe and slide cartridge to the detecting head, and the detecting head binds with piston rod of the cylinder is in the same place, and position switch is installed to the end around the cylinder, and the cylinder does not have the pole chamber and is connected with pressure relay, has time relay and controlling element in the electric cabinet, and pneumatic system is the cylinder air feed, electrical system contrasts through the pressure that does not have the pole chamber to cylinderpiston from the back end motion to time of front end and when moving, can provide the signal whether feed bin travelled empty. Visit time measuring to the unloading circumstances in the feed bin, electrical system is that time and the pressure that when moving does not have pole chamber of cylinderpiston from the back end motion to the front end contrasts through the circumstances of stretching out to the probe, can provide the signal whether feed bin travelled empty. The utility model discloses cylinder type feed bin unloading detection device's advantage is that the theory of operation is simple, and the operational reliability is high, and the constitution expense is maintained easily the end of than.
Description
Technical field
The utility model relates to a kind of feed bin emptying pick-up unit, particularly a kind of air-cylinder type feed bin emptying pick-up unit.
Background technology
In the conveying or transfer process of powdery or granular material, often need to material in feed bin whether emptying detects, to perform next process, conventional pick-up unit is radar level gauge and detection of weighing, but such device complex structure, somewhat expensive.
Summary of the invention
The purpose of this utility model is to propose that a kind of structure is simple, the air-cylinder type feed bin emptying pick-up unit of low cost.
The technical scheme realizing above-mentioned purpose is: a kind of air-cylinder type feed bin emptying pick-up unit, comprises detecting head, cylinder, pneumatic system and electric-control system; Detection head by pop one's head in and slide cartridge forms, electric-control system by closing position switch before pressure switch, cylinder, electric cabinet forms; It is characterized in that: detecting head by pop one's head in and slide cartridge form piston type slide pair, detecting head and cylinder piston rod are bound up, and the termination, front and back of cylinder is provided with position switch, and cylinder rodless cavity is connected with pressure switch; Free relay and control element in electric cabinet, pneumatic system is cylinder air feed; Electric-control system is contrasted by the pressure of rodless cavity when the time and the motion that cylinder piston are moved to front end from rear end, can give the signal of discharging bin whether emptying.
The course of work of the present utility model is: during air-cylinder type feed bin emptying pick-up unit normality, cylinder piston rod is in retrieving position, and probe is hidden in slide cartridge; Need detect feed bin whether emptying time, control to send instruction into system, electromagnetic switch valve events is to cylinder rodless cavity air feed, and cylinder piston rod reach promotes probe and stretches out, and the power output of cylinder only needs to overcome the friction force of self and probe sliding pair, and operating air pressure is less; When in feed bin during material emptying, probe can stretch out completely, and piston speed can arrive front end faster, and cylinder front position switch sends signal to control system, and solenoid directional control valve reversing cylinder piston rod drives spy to return its normal orientation; Because cylinder front position switch sends signal, to send front air cylinder piston movement short period time relay not operating, and cylinder operation air pressure lower pressure relay is not operating simultaneously, and electric-control system can judge feed bin emptying concurrent discharging bin emptying signal; When the non-emptying of material in feed bin, probe stretches out and is obstructed, piston ceases movement, rodless cavity operating air pressure raises and causes pressure switch action, simultaneously cylinder piston can not arrive front end and makes cylinder front position switch send signal thus time relay action in setting-up time, and solenoid directional control valve reversing cylinder piston rod drives spy to return its normal orientation; Electric-control system can judge the non-emptying of feed bin concurrent discharging bin material stock signal.Source of the gas regulating device is for keeping the stable of supply gas pressure.
The advantage of the utility model air-cylinder type feed bin emptying pick-up unit is that principle of work is simple, and functional reliability is high, the composition expense comparatively end, safeguards easily.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model embodiment.
In figure: 1. source of the gas regulating device; 2. solenoid directional control valve; 3. cylinder; 4. pressure switch; 5. position switch after cylinder; 6. cylinder front position switch; 7. pop one's head in; 8. slide cartridge; 9. material in feed bin.
Embodiment
As shown in Figure 1, a kind of air-cylinder type feed bin emptying pick-up unit, comprises detecting head, cylinder, pneumatic system and electric-control system.Detection head is by pop one's head in (7) and slide cartridge (8) forms, electric-control system is made up of pressure switch (4), cylinder front and back position switch (5,6), electric cabinet, detecting head by pop one's head in (7) and slide cartridge (8) to form piston type slide secondary, detection head is arranged on the wallboard of feed bin bottom; Cylinder (3) is double acting single lever-type cylinder, and probe (7) and cylinder piston rod are bound up, and slide cartridge (8) and cylinder block are rigidly connected, and the termination, front and back of cylinder is provided with magnetic position switch, cylinder piston is furnished with annular magnetic stripe; Cylinder rodless cavity is connected with pressure switch; Free relay and control element in electric cabinet; Pneumatic system is cylinder air feed.
