Abstract
The utility model relates to a net-shaped protective cover of a transmission drum at the belt conveyer tail under a coal mine well, in particular to the net-shaped protective cover of the transmission drum at the belt conveyer tail. The problems that existing fully-closed protective covers enable coal to be easily accumulated, coal cleaning is difficult and the like are solved. The net-shaped protective cover comprises a curved upper hood cover and a side hood cover connected beside the upper hood cover, and the upper hood cover and the side hood cover are net-shaped. The net-shaped protective cover is suitable for protection of a fully mechanized mining face and fully mechanized heading face movable type transmission drum at the belt conveyer tail, cleaning of off-line coal on a belt and treatment of dust produced by the transmission drum at the belt conveyer tail. A phenomenon that the dust formed by repeated extrusion of a rubber belt and the drum flies in the air and accordingly affects physical health of users and pollutes the environment when a belt conveyer conveys coal and the coal falls onto a lower-layer belt is avoided.
Description
Technical field
The utility model relates to belt machine end driving drum protector under a kind of coal mine, is specially the netted protective cover of a kind of belt machine end driving drum.
Background technology
According to the requirement of safety of coal mines pertinent regulations, protective cover must be installed in all running positions.And mine belt conveyer tail driving drum protective cover generally adopts the totally enclosed type that iron plate weldering system forms at present, has played the effect of protection personal safety.But because its moving belt conveyer receives its work plane condition, production link to influence, unload actual conditions such as coal breakage point, belt deviation, its belt deviation coal is more, causes " suppressing the tail driving drum " phenomenon to take place.Simultaneously the sideslip coal pushes the formation dust repeatedly through adhesive tape and cylinder and aloft flies upward, and influences health of human body, and contaminated environment causes dust to gather.
It " suppresses cylinder ", and phenomenon Chang Yi causes the conveyor operating load big, and is long apart from the belt starting difficulty, and aircraft tail cylinder damages, accident such as tear tape.Mode that the processing that rules require " is suppressed cylinder " is " stop the conveyor transportation, conveyor is carried out locking, adopt spade to stretch into clear coal in the tail driving drum protective cover ".And in the scene, down-hole, because worker's awareness of safety and lucky heart amount, part worker has taked to stretch into clear this mode of operating against regulations of coal in the operating belt machine end protective cover with spade in the process of handling " suppressing cylinder ".The belt that takes place like certain ore deposit accident of causing casualties of hurting sb.'s feelings is exactly a typical together worker case of handling the belt deviation coal violating the regulations.
Summary of the invention
The utility model provides a kind of belt machine end driving drum netted protective cover in order to solve the problems such as coal, cleaning difficulty of gathering easily that existing totally enclosed type protective cover is brought.
The technical scheme of the utility model is, the netted protective cover of a kind of belt machine end driving drum comprises the upper cover of curved, the side cover cap that the upper cover side connects, and upper cover, side cover cap are netted.
Be applicable to combine adopt, the protection of fully mechanized workface moving belt conveyer tail driving drum, the cleaning of belt deviation coal, the treating flour dust that the belt machine end driving drum produces.
Compare with the existing device that uses; The utility model has adopted all sides of tail protective cover has been designed to web form; When the sideslip coal falls into end belt and brings in the tail guard shield, utilize the aircraft tail cylinder operation that coal is pushed into the reticulated cell place, it utilizes the back coal of piling up to push away preceding coal; Freely flow out through its reticulated cell, artificial only need in its outside it being cleaned out with spade gets final product.Reach and do not stop the purpose that belt can be handled the sideslip coal.Atomization mechanism is installed simultaneously above it; Shower nozzle is aimed at tail driving drum and adhesive tape joint, when solving conveyor lower floor's belt falling into coal when the fortune coal, push the formation dust repeatedly through adhesive tape and cylinder and aloft fly upward; Influence health of human body, the phenomenon of contaminated environment.
