The wire I and the wire II are provided with wire outlet locking buckles 1-13 at the positions penetrating through the reserved holes on the supporting sealing covers 1-6.
The invention relates to a mechanical large block blockage detection device of a bulk material chute of a chain grate, which is arranged on two sides of a bulk material chute 5, wherein the upper end of the bulk material chute 5 is connected with a wind box flange of the chain grate or a roasting machine, the lower end of the bulk material chute is connected with a flange of a double-layer ash discharge valve 6, and an emergency cleaning door 3 is further arranged on the bulk material chute 5. The large block stop lever 7 is arranged in the bulk material chute 5, and the guide lugs 1-4 are respectively welded at the two ends of the large block stop lever 7, and as the guide grooves 1-3 are arranged at the two sides of the supporting seat 1-2, the guide lugs 1-4 of the large block stop lever 7 are arranged in the guide grooves 1-3 of the supporting seat 1-2, so that the large block stop lever 7 can move up and down and can not move back and forth and left and right; the lower planes at the two ends of the large block stop lever 7 are respectively connected with the upper part of the supporting spring 1-1, and the lower part of the supporting spring 1-1 is fixed with the supporting seat 1-2, even if the large block stop lever 7 and the gravity of the materials above the large block stop lever act on the supporting spring 1-1; limiting piles 1-7 are respectively arranged on the lower planes at the two ends of the large-block baffle rod 7 to prevent the supporting springs 1-1 from being crushed due to oversized blocks or excessive blocking materials; the movable insulating block 1-8 is fixed on the lower plane at two ends of the large-block baffle rod 7 through insulating bolts, the movable insulating block 1-8 is fixedly connected with one end of the buffer spring 1-9, the other end of the buffer spring 1-9 is connected with the movable trigger piece 1-10, the fixed trigger piece 1-11 is arranged right below the movable trigger piece 1-10, the fixed trigger piece 1-11 and the fixed insulating plate 1-12 are fixed on the supporting seat 1-2 through insulating bolts, a wire I is connected with the movable trigger piece 1-10, a wire II is connected with the fixed trigger piece 1-11, and the wire I and the wire II pass through the supporting sealing cover 1-6 and the wire outlet locking buckle 1-13 fixed on the supporting sealing cover 1-6 and then reach the junction box 2 for electric connection.

The supporting sealing cover 1-6 fixed with the supporting seat 1-2 is fixed on the bulk material chute 5 through bolts.
The bulk material is small pellet ore one by one and discontinuous, so that the bulk material can fall from the large block stop lever 7 (or between the large block stop lever 7 and the wall of the bulk material chute 5) when falling, namely the bulk material is collided on the large block stop lever 7 when falling, and the large block stop lever 7 can not act under the action of the supporting spring 1-1; however, when the large block appears, the large block can be blocked by the large block stop lever 7 (or the large block stop lever 7 and the wall of the bulk material chute 5), so that at least half of the gravity of the large block acts on one large block stop lever 7, and the subsequent bulk material falls on the large block, so that the large block stop lever 7 drives the trigger piece to act. The detection and alarm of the large block or the blocking material are truly realized on line.
The detection process comprises the following steps: under the action of gravity, the bulk cargo falls to the double-layer ash valve 6 in the bulk cargo chute 5, and is discharged to the belt conveyor through the double-layer ash valve 6. When large lump materials appear, the large lump materials can be blocked by a large lump material stop lever 7 in a bulk material chute 5, and the subsequent falling scattered materials fall on the large lump materials, the weight of the large lump materials and the scattered materials falling on the large lump material stop lever 7 acts on the large lump material stop lever 7, so that the large lump material stop lever 7 compresses a supporting spring 1-1, moves towards a fixed trigger piece 1-11 with a movable insulating block 1-8, a buffer spring 1-9 and a movable trigger piece 1-10, and enables the movable trigger piece 1-10 to be in contact with the fixed trigger piece 1-11, and outputs alarm information for finding large lump materials or blocking materials; when the block is too large or the block is blocked, the bottom of the limit pile 1-7 below the block stop lever 7 is directly contacted with the supporting seat 1-2 to prevent the supporting spring 1-1 from being crushed, but under the action of the buffer spring 1-9, the alarm is always given until the block or the block is removed, and under the action of the supporting spring 1-1, the block stop lever 7 moves along the moving insulating block 1-8, the buffer spring 1-9 and the moving trigger piece 1-10 in a direction away from the fixed trigger piece 1-11, the moving trigger piece 1-10 is separated from the fixed trigger piece 1-11, the alarm disappears, and the block stop lever 7 is reset.
The mechanical large-block blockage detection device for the bulk material chute of the chain grate machine can accurately detect whether large blocks or blockage occur in the bulk material chute in real time, and give an alarm when the large blocks or blockage occur, so that the problems that the conventional manual inspection is not timely found and the large blocks or blockage occur in the bulk material chute are difficult to accurately judge are avoided, the time and the labor are saved, and the device plays an important role in guaranteeing continuous and stable operation of a pellet production line; the two ends of each large block stop lever 7 have the capability of independently detecting and alarming, namely, no matter what angle and what position the large block falls on the large block stop lever 7, the weight of the block or the blocking material can output an alarm signal; the invention is a mechanical detection, reliable, stable and long-lived.
