Apron feeder is widely used in mining, metallurgy, building materials and coal industries. The machine is mainly used under the silo and funnel with a certain bin pressure, to send a variety of large-capacity materials to a variety of crushing, screening or transportation equipment in a short distance, uniform and continuous. It is not only suitable for processing coarse grained materials, fine grained materials are also suitable, but also can complete heavy work in harsh environments, and has greater adaptability to changes in material particle size composition, temperature, viscosity and humidity, and uniform, accurate and reliable feeding.
Apron feeder chain rail and chain plate because of the bolt connection, and the working environment is very bad, easy to make the chain plate bolt deformation and elongation, need to be replaced in time. However, in the process of conveying materials, due to the direct contact between the material and the surface of the chain plate, it is easy to accumulate material around the nut of the bolt, which needs to be cleaned in time, otherwise it is difficult to replace the bolt in time, and affect the operation of the equipment. At present, for the bulk cleaning of the bolt head, many chisels and hand hammers are used to clean the bulk manually first, then the bolt head is cut off, and then the bolts are removed and replaced, resulting in extremely low maintenance efficiency, heavy maintenance workload, long time and high labor intensity. The purpose is to overcome the shortcomings of the prior art and provide a fast, convenient and labor-saving cleaning device for the bolt accumulation of apron feeder chain plate. Technical measures to achieve the above purposes: a cleaning device for bolt deposit material of apron feeder chain plate comprises an outer sleeve made of metal, a circular groove arranged in the upper end of the outer sleeve, an inner sleeve made of metal tightly fitted in the circular groove, and an electric wrench used in the upper end of the outer sleeve: the lower part of the outer sleeve is provided with an oblique scraping groove. It is characterized in that the upper end of the inner sleeve is connected with a reinforcing ring. The utility model is characterized in that the electric wrench is composed of a handle, a motor connected with one end of the handle, a rotating rod connected with the motor, and a connecting piece connected to the other end of the rotating rod: the shape of the connecting piece is cruciform or square. It is characterized in that the bottom of the inner sleeve is connected with a card slot matching the electric wrench. It is characterized in that the shape of the card slot is matched with the shape of the connecting piece. The features of the new model are as follows: replacing manual cleaning of bolt accumulation, shortening the cleaning time, improving the efficiency of overhaul operation, reducing the labor intensity of overhaul workers, ensuring the amount of overhaul work, improving the stable operation of apron feeder, and simple structure and easy implementation.
The cleaning device for bolt deposit material of apron feeder chain plate includes a metal outer sleeve, a circular groove formed by processing the upper end of the outer sleeve, interference matching with the installed metal inner sleeve in the circular groove of the outer sleeve, an electric wrench used with the upper end of the outer sleeve, and an oblique scraping discharge groove processed and distributed at the lower part of the outer sleeve. The upper end of the inner sleeve is connected with an integral machining or welded reinforcing ring. The electric wrench consists of a handle, a motor connected to one end of the handle, a rotating rod connected to the motor, and a connector threaded or welded to the other end of the rotating rod: the shape of the connector is cruciform or square. The bottom of the inner sleeve is welded or connected with the electric wrench through the support card groove, the shape of the card groove is matched with the shape of the connector, and is tightly bonded. When the utility model needs to be used, the lower end of the outer sleeve is first set to the bolt to be removed, and then the connecting piece on the electric wrench is fixed to the bottom card slot of the inner sleeve, and the motor of the electric wrench is started. At this time, the rotating rod connected to the motor drives the inner sleeve through the card slot, and the inner sleeve then the outer sleeve, so that the deposit on the bolt is scraped off by the inclined scraping and discharging groove. After the end of scraping, stop the operation of the electric wrench, and then remove the sleeve simple. The specific mode of implementation is only an example, and is not an implementation limitation of the utility model.
