Example 1:
referring to fig. 1 and 2, the invention provides an automatic sprinkling irrigation device for magnetic suspension liquid for magnetic powder inspection, which comprises an upper tank body 1 and a lower tank body 2, wherein the upper tank body 1 is detachably connected with the lower tank body 2.
Specifically, in this embodiment, the upper tank body 1 and the lower tank body 2 can be detachably connected by the screw thread arranged on the inner side wall of the upper tank body 1 and the screw thread arranged on the outer side wall of the lower tank body, and certainly, the upper tank body 1 and the lower tank body 2 can also be detachably connected by the screw thread arranged on the outer side wall of the upper tank body 1 and the screw thread arranged on the inner side wall of the lower tank body; the embodiment of the invention does not limit the concrete connection mode of the upper tank body 1 and the lower tank body 2.
The lower tank body 2 is used for storing magnetic suspension.

A first gear can be sleeved on an output shaft of the driving motor, the first gear is matched with a second gear, the second gear is used for driving the stirring mechanism to work, and the output shaft of the driving motor is used for driving the water pump 6 to work. Therefore, only one driving motor is needed to drive the water pump 6 and the stirring mechanism to work simultaneously, and the space of the upper tank body 1 is saved.
The stirring mechanism may be a stirring shaft 14 which stirs the magnetic suspension in the lower tank 2 as it rotates.
As an alternative embodiment, the stirring mechanism includes a stirring shaft 14, a shaft sleeve 13 at least partially sleeved on the stirring shaft 14, and a stirring blade 131 disposed on the shaft sleeve 13; the stirring shaft 14 is driven by a driving motor to rotate. The stirring shaft 14 is arranged in the center of the second gear and driven by the second gear to rotate.
As the shaft sleeve 13 is sleeved on the stirring shaft 14, the stirring mechanism can be disassembled, the length of the stirring shaft 14 does not need to be very long, and when the length of the stirring mechanism penetrating into the lower tank body needs to be changed, the length of the shaft sleeve 13 only needs to be changed, so that the service life of the stirring shaft 14 is prolonged. In addition, because the shaft sleeve 13 is immersed in the magnetic suspension for a long time, and the magnetic suspension has certain corrosivity, if the stirring shaft 14 is used for stirring the magnetic suspension for a long time, the stirring shaft is easy to corrode; the stirring shaft 14 is matched with a driving motor, so that the stirring shaft is inconvenient to replace. Adopt the scheme that this application provided, establish axle sleeve 13 cover on (mixing) shaft 14, only need change axle sleeve 13 can, axle sleeve 13's material can be plastics, low cost to can obviously reduce the cost of maintenance of this device, improve life.

In the prior art, the magnetic suspension is mixed by manually shaking, but the mode has obvious low efficiency, wastes time and labor and has poor mixing effect. The stirring mechanism has been added to the device of this application, stirs under driving motor's drive automatically, has improved stirring efficiency. However, since the driving motor drives the water pump and the stirring mechanism to work at the same time, the magnetic suspension which is just sprayed is sprayed out without being fully stirred, and the uniformity of the magnetic suspension cannot be ensured. Therefore, the water inlet pipe 8 of the water pump 6 is provided with the electromagnetic valve, and the control circuit is used for controlling the electromagnetic valve to be opened after the preset time, namely the electromagnetic valve is controlled by the control circuit to be opened after the preset time. Therefore, when the device works, the stirring mechanism works firstly, after the preset time, the mixing of the magnetic suspension is relatively uniform, the control circuit controls the electromagnetic valve to open, the water pump 6 pumps the magnetic suspension, the magnetic suspension is ensured to be fully mixed every time, and any manual stirring operation is not needed.
The control circuit may be a time relay. A time delay may be preset, and after the power supply 3 is turned on, the time relay turns on the circuit after a preset time delay to control the solenoid valve to be opened.
In the magnetic powder inspection process, the spraying time of the magnetic suspension is accurately controlled, the precision of magnetic powder inspection can be improved, at present, the spraying time is automatically controlled by an operator, and if the operator is not concentrated, the spraying time is too long or too short easily. In order to solve the problem, the upper tank body 1 is also provided with a timing circuit, and the switch 5 and the timing circuit are respectively connected with the power supply 3; the timing circuit is used for controlling the power supply 3 to be switched off after a preset time. Therefore, an operator only needs to input spraying time before spraying the magnetic suspension, and the precision and accuracy of magnetic powder inspection are further improved.
The switch 5 may be a simple switch button, or may be a push switch, a self-locking switch or a non-self-locking switch.
And a water outlet pipe 7 of the water pump 6 is connected with the nozzle 9. The nozzle 9 is arranged on the side wall of the upper tank body 1.
Specifically, the water outlet pipe 7 of the water pump 6 can be arranged at the bottom of the water pump or at other parts of the water pump, and a water pipe at one end can be additionally connected between the water pump and the nozzle 9.
To improve the spraying effect of the magnetic suspension, the nozzle 9 may be an atomizer.
In order to replace the nozzle 9 conveniently, a quick-connection socket is further arranged on the upper tank body 1 and connected with the water outlet pipe 7, and the nozzle 9 is connected with the water outlet pipe 7 through the quick-connection socket.
