Detailed Description

In order to make the purpose and technical solution of the present invention clearer, the following description is made with reference to the accompanying drawings and embodiments to further explain the present invention:

the device for detecting the blockage of the large-particle-size stone chute shown in the figures 1 to 3 comprises a material accumulating bin 1, wherein the material accumulating bin is connected with a chute 2; further comprising: a window is arranged on the side edge of the material accumulating bin 1; the movable plate 3 is hinged to the window; a contact rod 4 mounted on the movable plate 3; the triangular contact 5 is arranged on the contact rod 4; and the contact sensor 6 is arranged on the outer side of the movable plate and is spaced from the movable plate by a certain distance, and is matched with the triangular contact 5 for use.

Preferably, the hinge structure of the movable plate 3 is: fixing rings 31 are arranged on two sides above the window; a connecting rod 32 is arranged above the movable plate, and the connecting rod 32 passes through the two fixing rings 31 to be installed.

Preferably, the contact sensor 6 is mounted by means of a fixed bar 7; connecting rods 71 are arranged on two sides of the fixing rod 7, and two ends of each connecting rod 71 are fixedly installed on the material accumulating bin 1.

Preferably, the touch sensor 6 is externally wrapped with a protective layer 8.
