Description

Technical Field

[0001] The utility model relates to the technical field of gates, in particular to a controller for a discharging self-cleaning gate exclusive for a scraper conveyor. Background Art

[0002] Scraper conveyor is a drag chain conveyor, which can convey various powder, small particles and block-shaped bulk materials with good fluidity, such as ore, coal, sand, gypsum, cement, grain, etc. It is widely used in metallurgy, grain, power plants, ports, and underground mines such as coal mines, salt mines, gypsum mines, etc. However, it is not suitable for conveying brittle materials that are easy to break and wear. The basic structure consists of a head, a tail, a scraper chain, a transition trough, a middle trough and a baffle. Scraper conveyor is mainly used for horizontal conveying of materials in a closed state, without dust and low breakage. It is widely used in grain storage and processing.

[0003] A discharge gate is generally installed at the bottom of the scraper conveyor. The guide grooves of some existing gates are generally lower than the material running plane of the scraper conveyor, which makes it easy for grain materials to accumulate in the groove after the gate is closed. Grain materials are prone to mildew when accumulated in the groove for a long time, which reduces the storage quality of grain materials. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings that the guide grooves of some existing gates are generally lower than the material running plane of the scraper conveyor, which makes it easy for grain materials to accumulate in the grooves after the gate is closed, and the grain materials are easily moldy when accumulated in the grooves for a long time, thereby reducing the quality of the grain materials. A controller for a discharging self-cleaning gate exclusively for scraper conveyors is provided.

[0005] The purpose of the utility model is achieved through the following technical solutions: a controller for a self-cleaning discharge gate exclusive to a scraper conveyor, comprising a scraper feeding surface, a feeding port being provided on the scraper feeding surface, a gate being installed on the bottom surface of the feeding port, and two groups of corresponding door panels being installed on the gate, the two groups of door panels being arranged in a split-open manner, the two groups of door panels being fitted with the scraper feeding surface, two groups of rotatable hinge shafts being installed in the gate, the two groups of hinge shafts being respectively connected to the bottom surfaces of the two groups of door panels, two groups of cylinders being installed on the gate, the cylinders being connected to the hinge shafts through hinge plates, and by arranging the door panels to fit with the scraper feeding surface, no groove can be formed between the scraper feeding surface and the door panels, thereby preventing materials from remaining in the gate during the gate unloading process, thereby preventing grain materials from remaining in the gate and causing mildew, thereby ensuring the storage quality of grain materials.

[0006] A further technical solution is that folding plates are installed on the sides of the two sets of door panels that are close to each other, and the two sets of folding plates are in contact with each other. By providing the folding plates, the sealing between the two sets of door panels can be improved, thereby preventing leakage of grain materials.

[0007] A further technical solution is that a bearing is installed on the side wall of the gate, and the twist shaft is connected to the inner ring of the bearing.

[0008] A further technical solution is that a sealing sleeve is installed on the gate, and the bearing is installed in the sealing sleeve. By providing the sealing sleeve, the sealing effect of the bearing can be improved, dust and impurities can be prevented from entering the bearing, and the service life of the bearing can be guaranteed.

[0009] A further technical solution is that two sets of fixing plates corresponding to the blanking openings are installed on the scraper conveying surface, and the fixing plates are located above the door panels. By setting the fixing plates, the bearing strength of the blanking opening can be improved.

[0010] A further technical solution is that the two sets of fixed plates are cross-arranged. By cross-arranging the two sets of fixed plates, materials can be quickly dropped when the door panel is opened to avoid clogging of the gate.

[0011] The utility model has the following advantages: the utility model can make no groove exist between the scraper feeding surface and the door plate by arranging the door plate to fit with the scraper feeding surface, thereby avoiding material residue in the gate during the gate unloading process, thereby avoiding grain material residue in the gate and mildew, ensuring the storage quality of grain material, and by arranging the folding plate, the sealing between the two sets of door plates can be improved, thereby avoiding leakage of grain material.
