A fourth spring 30 is fixedly connected to the left side of the pressure sensor 29.

The working principle is as follows: when the device works, the driving shaft 14 drives the chain wheel 4 to rotate, the chain wheel 4 drives the material tray 3 to convey materials through the conveying chain 2, when the chain wheel 4 rotates too fast, the centrifugal force of the arc-shaped rod 9 inside is increased, the arc-shaped rod 9 is separated from the rod sleeve 12 to move outwards, the arc-shaped rods 9 on the upper side and the lower side simultaneously move outwards through the action of the linkage rod 11, the second friction plate 13 is driven to be contacted with the first friction plate 5 through the arc-shaped rod 9, the effect of reducing the speed of the chain wheel 4 is achieved, meanwhile, the arc-shaped rod 9 drives the movable rod 8 to move upwards, the movable rod 8 upwards extrudes the first spring 7, the fixed rod 6 moves towards the movable rod 8 through the groove 801, after the speed of the chain wheel 4 is reduced, the centrifugal force borne by the arc-shaped rod 9 is reduced, at the moment, the first spring 7 drives the movable rod 8 to move downwards through the reaction force, the movable rod 8 drives the arc-shaped, meanwhile, the arc-shaped rod 9 drives the arc-shaped rod 9 above to move downwards through the linkage rod 11 and return into the rod sleeve 12, so that the second friction plates 13 on the upper side and the lower side are separated from the first friction plate 5 at the same time, and the chain wheel 4 continues to operate. Thereby the effect that the materials in the pipeline are not easy to be broken and the chain wheel rotates too fast and automatically reduces the speed is achieved.

Then the material tray 3 is driven by the conveying chain 2 to move into the discharging bin 15, the material tray 3 drives the motion rod 18 to move towards the right side, the motion rod 18 drives the supporting block 17 to move towards the right side in the sliding chute 1501, meanwhile, the supporting block 17 pulls the second spring 16 to extend towards the right side, the motion rod 18 moves towards the right side to push the push rod 28 to move towards the air bag chamber 26, the push rod 28 drives the second extrusion plate 27 to extrude the second air bag 25, meanwhile, the second extrusion plate 27 is far away from the pressure sensor 29, the gas in the second air bag 25 runs into the first air bag 23 through the gas conveying hose 24, so that the first air bag 23 extrudes the first extrusion plate 22 upwards, the first extrusion plate 22 extrudes the telescopic rod 20 and the third spring 21 upwards, when the material tray 3 does not extrude the motion rod 18 any more, the motion rod 18 moves towards the left side to reset under the action of the first spring 7, at the moment, the push rod 28 does not extrude the motion rod 18, and the third spring 21 drives, the first extrusion plate 22 extrudes the first air bag 23, because the acting force of the third spring 21 is smaller, the gas in the first air bag 23 will slowly run into the second air bag 25 through the gas hose 24, because the weight of the push rod 28 and the second extrusion plate 27 is lighter, the second air bag 25 expands to extrude the second extrusion plate 27 to move to the left, when the next material tray 3 continues to drive the motion rod 18 to move to the right, the push rod 28 is pushed to make the second extrusion plate 27 extrude the second air bag 25 to make the gas run into the first air bag 23, and the operation is repeated, when the conveying chain 2 is broken, the conveying chain 2 will not drive the material tray 3 to push the motion rod 18, because there is no pushing of the material tray 3, the third spring 21 in the motion rod 18 continues to drive the first extrusion plate 22 to move downwards, the first extrusion plate 22 continues to extrude the gas in the first air bag 23 to run into the second air bag 25, until the second air bag 25 pushes the second extrusion plate 27 to extrude the pressure sensor 29 and the fourth spring 30, at the moment, the pressure applied to the pressure sensor 29 is greater than the set value, and the pressure sensor 29 stops the operation of the driving shaft 14 through an electric signal, so that the conveying chain 2 stops running, and the effects of chain breakage protection and difficulty in equipment damage are achieved.
