Description of the embodiments
Aiming at the problems in the prior art, the utility model provides the automatic warning device for the large foreign matters in the chute of the belt conveyor, which can automatically trigger a pull switch when the large foreign matters drop at the discharging position of the chute of the belt conveyor, so that the belt conveyor is stopped, a large amount of overflows are avoided, the labor intensity of cleaning staff is reduced, accidents such as belt breakage and the like are prevented, and enterprise losses are reduced.
Referring to fig. 1 and 2, the utility model mainly comprises a pull switch 4, a material collecting barrel 7, a baffle plate 8, a fixed pulley 9 and a pull rope 10, and the manufacturing and working processes of the utility model are as follows:
1. material preparation
Materials to be prepared include: a 20kg capacity material collecting barrel 7, a common pull-cord switch 4, a rectangular baffle plate 8, a fixed pulley 9 and a pull cord 10 made of a steel wire rope.
2. Manufacturing method
The material baffle 8 is fixed on the side wall of the belt conveyor chute 6, which is close to one side of a discharge hole of the belt conveyor, and the lower end of the material baffle 8 is higher than the height of the upper material on the belt when the belt conveyor is in normal operation and lower than the height of the discharge hole of the belt conveyor chute 6. The pull switch 4 and the fixed pulley 9 are fixed on the side part of the frame 3 of the belt conveyor, the signal output end of the pull switch 4 is connected with a belt conveyor control system, the pull rope 10 bypasses the fixed pulley 9, one end of the pull rope 10 is connected with the pull switch 4, and the other end of the pull rope is connected with the material collecting barrel 7 after sagging. The material collecting barrel 7 is arranged below the belt conveyor chute 6 and the baffle plate 8, when foreign matters are blocked at the discharging position of the belt conveyor chute 6 to cause overflow, the overflowed material from the belt conveyor falls into the material collecting barrel 7, and a pull switch is automatically triggered under the gravity action of the belt conveyor chute 6 and the material, so that the belt conveyor is stopped.
3. Working process
When the belt conveyor normally operates, a material collecting barrel is respectively hung below two sides of a feed opening of a chute of the belt conveyor.
When the blanking mouth of the chute of the belt conveyor drops large foreign matters, the normal materials cannot smoothly pass through the belt conveyor due to the blocking of the blanking mouth, the large foreign matters are blocked by the baffle plate and cannot enter subsequent equipment (such as a sintering machine), the blocking of the discharging mouth of the belt conveyor can be avoided, the large foreign matters are matched with the baffle plate, and the materials are forced to overflow at the baffle plate and fall into the material collecting barrel.
The gravity of the material collecting barrel and the materials received by the material collecting barrel acts on the pull rope switch 4 through the pull rope 10, when the weight of the material collecting barrel and the materials received by the material collecting barrel is larger than a set value (5 kg), the force born by the pull rope switch 4 reaches the set value, the pull rope switch 4 is triggered, the pull rope switch 4 outputs an alarm signal to the belt conveyor control system, and the belt conveyor stops running.
After the belt conveyor is stopped, operators can quickly check the site situation to carry out quick treatment.
The beneficial effects of the utility model are as follows:
when the large foreign matters fall off from the blanking part of the chute of the belt conveyor, the large foreign matters are matched with the baffle plate, so that the pull rope switch is automatically triggered after normal materials overflow from the belt conveyor, the belt conveyor is suddenly stopped, a large amount of materials are prevented from overflowing, and the abrasion to the belt is reduced.
