Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, a kind of accuracy of detection height, strong, the easy-to-install strength cleaning type of adaptability infrared seeding monitoring sensor are provided.
For achieving the above object, the present invention adopts following technical proposals: strength cleaning type infrared seeding monitoring sensor of the present invention comprises discharging tube, infrared receiving tube, infrared transmitting tube, circuit board, signal cable.Also comprise sensor housing, sleeve pipe, pressure cap, gas path joint, the gas circuit flexible pipe, gas source interface, threeway, seal, water joint, described infrared receiving tube and infrared transmitting tube are integrated on the same circuit board, by the pressure cap squeezing bushing, the peripheral localized axial of this circuit board is fitted on the boss of sensor housing, make between the boss of this circuit board and sleeve pipe and sensor housing and constitute partial aperture, and communicate with the inner chamber of sleeve pipe, the gas circuit flexible pipe is tightly connected by gas path joint and pressure cap, and this gas circuit flexible pipe communicates with the inner chamber of sleeve pipe, this gas circuit flexible pipe is provided with threeway, this threeway external gas source interface, described signal cable one end links to each other with this circuit board, the other end passes the gas circuit flexible pipe, and is fixed on the outer end of this gas circuit flexible pipe by seal and water joint.
As the improvement of strength cleaning type infrared seeding monitoring sensor of the present invention, described board design is circular and the symmetry angular shape that cuts off, and makes between the boss of this circuit board and sleeve pipe and sensor housing to constitute partial aperture.
After adopting technique scheme, the invention has the beneficial effects as follows:
1. accuracy of detection height.Constitute partial aperture between the boss of this circuit board and sleeve pipe and sensor housing, guarantee under electric signal transmission and the bubble-tight prerequisite thereby be implemented in, compressed air is blown into sensor internal from the space between gas circuit flexible pipe and the signal cable, finally blow out from the partial aperture that constitutes between the boss of circuit board and sleeve pipe and sensor housing, and form turbulent flow at infrared transmitting tube and infrared receiving tube surf zone, dust can not be gathered, realize continuing dedusting.It is stable to make sensor detect property retention, has improved accuracy of detection.
2. adaptability is strong.Described infrared receiving tube and infrared transmitting tube are integrated on the same circuit board, promptly be installed in same infrared transmitting tube and infrared receiving tube the same side of being positioned at discharging tube on the circuit board, form radial surveyed area, be not easy to take place omission for the seed of dispersing the whereabouts, can be used for the environment, strong of judder for the adaptability of seed seed size.
3. be easy to install.Described infrared receiving tube and infrared transmitting tube are integrated on the same circuit board, have reduced sensor bulk, need not to consider the axiality of infrared transmitting tube and infrared receiving tube during installation.
