Description

Technical Field

[0001] The utility model relates to the technical field of coal transportation, in particular to an anti-stuck structure of a plate door of a scraper conveyor. Background Art

[0002] The scraper conveyor is used to transport coal slime. Its working principle is that the open chute is used as the bearing member of coal, gangue or materials, and the scraper is fixed on the chain (composed of the scraper chain) as the traction member. When the head transmission part is started, the sprocket on the head shaft is driven to rotate, so that the scraper chain circulates and drives the material to move along the chute until it is unloaded at the head. The scraper chain bypasses the sprocket to perform a stepless closed loop operation to complete the material transportation.

[0003] When conveying bulk raw coal, the raw coal that falls on the gate is dry bulk material. Dry bulk material will not be adsorbed on the steel plate of the gate, and there will be no major impact during the gate switch process. The gate can be opened and closed smoothly. Normally, the gate is closed. When conveying coal slime, the coal slime has a high moisture content and is very easy to adhere to the gap between the bottom plate of the scraper conveyor and the gate. In addition, due to the friction between the bottom plate of the scraper conveyor and the gate during the operation of the scraper conveyor, the bottom plate temperature is high, which causes the coal slime in the gap to lose moisture and solidify, resulting in the bottom plate of the scraper conveyor and the gate sticking together. When the gate needs to be opened, the bottom plate of the scraper conveyor and the gate are firmly bonded, causing the gate to get stuck during the switch process, or even unable to open. Summary of the invention

[0004] In order to solve the problems existing in the prior art, the utility model provides a scraper conveyor plate door anti-stuck structure, which has a simple structure and is easy to operate and use.

[0005] The utility model provides a technical solution to the above technical problems as follows: a scraper conveyor plug-in door anti-stuck structure, comprising a scraper conveyor body, a scraper conveyor bottom plate, a square support frame fixedly connected to the scraper conveyor bottom plate, a plug-in door runway, and a material unloading plug-in door movably placed on the plug-in door runway, the plug-in door runway being fixedly connected to the inner side of the square support frame, a plurality of plug-in door runway air holes being provided on the plug-in door runway on both sides, a plurality of material unloading plug-in door air holes being provided on both sides of the material unloading plug-in door, and the unloading plug-in door air holes being overlapped and connected with the plug-in door runway air holes.

[0006] Furthermore, the scraper conveyor bottom plate is fixedly connected to the square support frame by welding.

[0007] Furthermore, the plug-in door runway is fixedly connected to the inner side of the square support frame on three sides by welding.

[0008] Furthermore, the width of the unloading plug-in door is greater than the width of the unloading opening.

[0009] Preferably, the square support frame is welded from 10# channel steel, and the plug-in door runway 4 is made of 8# angle steel.

[0010] Compared with the prior art, the utility model has the following beneficial effects: during the coal slime conveying process, the coal slime entering the unloading plug-in gate and the bottom plate of the scraper conveyor will leak out from the vent holes of the unloading plug-in gate and the vent holes of the plug-in runway, effectively avoiding the accumulation of coal slime between the plug-in runway and the unloading plug-in gate, the bottom plate of the scraper conveyor and the unloading plug-in gate, so that the unloading plug-in gate no longer has a stuck state of being unable to open or close. The structure is simple and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
