Detailed Description
The invention will be further explained by way of example with reference to the accompanying drawings.
Referring to the attached drawings, a belt conveyor groove blockage detection device comprises a detection hole 7, a micro-motion cover plate 1, a cover plate lining 3, an articulated shaft 2 and a micro-motion switch 5, wherein the detection hole 7 is formed in the chute wall 4, the detection hole 7 is provided with an edge 8 protruding out of the chute wall 4, the micro-motion cover plate 1 is connected with the chute wall 4 through the articulated shaft 2, the articulated shaft 2 is located above the detection hole 7, the inner wall of the micro-motion cover plate 1 is in contact with the edge 8, the cover plate lining 3 is connected to the inner wall of the micro-motion cover plate 1 in a welded mode, the shape of the cover plate lining is matched with the detection hole 7, the cover plate lining 3 is parallel to the chute wall 4, the micro-motion switch 5 is fixed on the chute wall 4, and the inner. The included angle formed by the micro-motion cover plate 1 and the chute wall 4 is 12 degrees. The inner plane of the cover plate lining 3 is 10mm concave to the inner surface of the chute wall 4. The detection hole 7 is a rectangular hole with the side length of 400 multiplied by 550 mm. The thickness of the micro-motion cover plate 1 is 4 mm. The lower edge of the detection hole 7 is arranged 500 mm above the belt.
In the embodiment, the micro-motion cover plate 1 is connected with the chute wall plate 4 through the hinge shaft 2, can be opened in a micro-motion manner up and down, and can be automatically reset by means of self gravity; the microswitch 5 is fixed on the chute wall, and the microswitch contact 6 is tightly attached to the microswitch cover plate 1; the included angle that fine motion apron 1 and chute wall 4 become, the contact of 1 inner wall of fine motion apron and border 8 to do benefit to fine motion apron 1 and lean on self gravity to form good sealedly with inspection hole 2, avoid detecting hole 2 department splash material in the use. The cover plate lining 3 is fixed on the inching cover 1, the inner side of the cover plate lining 3 is parallel to the chute wall 4 and is concave to the chute wall by 10mm, so that the transverse pressure of the material 11 is maximum to the moment of the hinge shaft 2 during material blockage, and the detection device is prevented from losing efficacy due to the fact that the material is stuck at the position of the detection hole 7.
During belt feeder chute putty, material 11 is to lapping on the transverse pressure of 3 inside linings transmits micro-gap cover plate 1, and micro-gap cover plate 1 is outwards opened, drives micro-gap switch contact 6 and removes to trigger position A2 from initial position A1, and micro-gap switch 5 sends the stifled groove signal, and backstage treater sends the warning and belt feeder instruction of shutting down according to stifled groove signal, has avoided because stifled groove causes to spill the material and the bad problem of belt wearing and tearing.
