Abstract
The utility model discloses a protection device for a head chute of a belt conveyor in , which comprises a bracket, a supporting shaft and a material receiving plate. The supporting shaft is horizontally provided on the bracket. The material receiving plate is hinged with the supporting shaft. The bracket is provided with a proximity switch which can be touched above one end of the material receiving plate. The bracket is provided below the head chute of the belt conveyor. One end of the material receiving plate is provided below an observation door. When the limestone fills the chute and overflows through the observation door, the limestone falls on the material receiving plate when falls out of the chute. Because the supporting shaft is hinged with the material receiving plate, one end of the material receiving plate is stressed and rotates downwards according to a lever principle, and the other end of the material receiving plate rotates upwards. When the other end of the material receiving plate moves upwards to the proximity switch, the contact switch transmits out a signal for indicating the belt conveyor to stop operation thereby ensuring no damage of the belt. The material jam protection device for the head chute of the belt conveyor has the following advantages: reasonable design, simple structure, easy fabrication and mounting, and capability of finding the material jam in time for obtaining a purpose of in-time settlement thereby reducing the loss of the enterprise.
Description
Technical field
The utility model relates to a kind of band conveyor head chute putty fender guard.
Background technology
As everyone knows; limestone is an indispensable raw material of producing cement; the numerous domestic cement mill generally all uses band conveyor to carry limestone; because limestone contains wet adhesive material in recovery process; very easily cause band conveyor head chute to stop up; stopping up the back limestone can be full of chute very soon and then overflow, drop to outside the chute outdoors by observing; thereby damage operating belt; serious needs are shut down maintenance or are changed belt; this just has influence on the continuity of production, and then has influence on the production and the economic benefit of enterprise.
The utility model content
The utility model provides a kind of band conveyor head chute putty fender guard in order to solve weak point of the prior art.
For solving the problems of the technologies described above; the utility model adopts following technical scheme: band conveyor head chute putty fender guard; comprise support, pivot shaft and the plate that connects material; the pivot shaft level is located on the support; connect material plate and pivot shaft is hinged, above plate one end that connects material, be provided with on the support can touch near switch.
Adopt technique scheme, support is arranged on the outer bottom of band conveyor head chute, plate one end that connects material is positioned at observes student side, when limestone is full of chute and then will falls on the plate that connects material outside the chute by observing to overflow outdoors, drop to, because pivot shaft is hinged with the plate that connects material, according to lever principle, stressed the rotating of this end of plate connects material, the plate other end that connects material upwards rotates, when upwards roof pressure arrives near switch, contact switch sends signal, and the indication band conveyor quits work, thereby guarantees that belt is injury-free.The utility model is reasonable in design, simple in structure, be easy to make and install, and can in time find the material blockage problem, reaching the purpose of timely solution, thereby reduced enterprises' loss.
Description of drawings
Fig. 1 is the structural representation of the utility model mode of operation.
The specific embodiment
As shown in Figure 1; band conveyor head chute putty fender guard of the present utility model; comprise support 1, pivot shaft 2 and the plate 3 that connects material; pivot shaft 2 levels are located on the support 1; the plate 3 that connects material is hinged with pivot shaft 2; plate 3 one ends that connect material are provided with contact plate 4, above contact plate 4, be provided with on the support 1 can touch near switch 5.
During use, support 1 is arranged on the chute 7 outer bottoms of band conveyor head 6, plate 3 one ends that connect material are positioned at observes door 8 belows, when limestone is full of chute 7 and then excessive by observing door 8, drop to and to fall (the diagram arrow is the blanking direction) on the plate 3 that connects material outside the chute 7, because pivot shaft 2 is hinged with the plate 3 that connects material, according to lever principle, connect material plate 3 this end is stressed and rotate, plate 3 other end contact plates 4 that connect material upwards rotate, when contact plate 4 upwards roof pressure near switch 5 time, send signal near switch 5, the indication band conveyor quits work, thereby guarantees that belt is injury-free.
