Description

Technical Field

[0001] This utility model relates to the field of electric furnace technology, specifically to a feeding device for an electric furnace. Background Technology

[0002] An electric furnace is a device that uses electrical energy to heat materials. It can heat various non-metallic materials, promote chemical reactions, and produce various high-purity metals and alloys. Electric furnaces are widely used in chemical, metallurgical, building materials, and machinery industries. However, the deep working space of an electric furnace makes it inconvenient for operators to place materials, resulting in slow feeding speeds and the possibility of materials falling during the feeding process. Therefore, we propose a feeding device for electric furnaces. Utility Model Content

[0003] The purpose of this invention is to provide a feeding device for an electric furnace to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a feeding device for an electric furnace, comprising a conveyor seat, a support plate fixedly connected to the left rear end of the top of the conveyor seat, a third gear movably connected to the lower left end of the inner surface of the support plate, a toothed plate meshing with the outer surface of the third gear, a sliding plate fixedly connected to the front of the toothed plate, arc-shaped blocks fixedly connected to the left and right sides of the back of the sliding plate, and a frame movably connected to the outer surface of the sliding plate.

[0005] Preferably, a driven roller is movably connected to the left end of the inner surface of the conveyor seat, and a driving roller is movably connected to the right end of the inner surface of the conveyor seat, and the driving roller is connected to the driven roller via a conveyor belt.

[0006] Preferably, a motor is fixedly connected to the back of the conveyor seat, and the output shaft of the motor is fixedly connected to the back of the drive roller.

[0007] Preferably, the upper end of the inner surface of the conveyor seat is movably connected with a plurality of equidistant auxiliary rollers, the lower end of the inner surface of the conveyor seat is fixedly connected with a plurality of equidistant reinforcing rods, and the front and rear ends of the right side of the conveyor seat are both fixedly connected with support legs.

[0008] Preferably, a slide is fixedly connected to the top of the frame, a slider is slidably connected to the inner surface of the slide, and the slider is fixedly connected to the upper left end of the front of the support plate.

[0009] Preferably, a sleeve is fixedly connected to the upper right end of the front side of the sliding plate, a plurality of equidistant springs are fixedly connected to the top of the inner cavity of the sleeve, a scraper is fixedly connected to the bottom of the springs, a slot is provided at the upper end of the inner surface of the scraper and the lower end of the inner cavity of the sleeve, an electric telescopic rod is fixedly connected to the top of the sleeve, and a locking plate is fixedly connected to the telescopic end of the electric telescopic rod.

[0010] Preferably, a reinforcing plate is fixedly connected to the lower end of the front side of the support plate, and the end of the reinforcing plate is fixedly connected to the top of the conveyor seat. A second gear is movably connected to the left end of the back side of the support plate. The rear end of the second gear is connected to a third gear through a single-sided toothed synchronous belt. A first gear is meshed with the right side of the second gear. The first gear is movably connected to the back side of the support plate, and the rear end of the first gear is connected to the driven roller through a single-sided toothed synchronous belt.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention places the left end of the conveyor seat in contact with the material pile. Turning on the motor drives the active roller to rotate, which, in conjunction with the driven roller, moves the conveyor belt, thus achieving automatic material feeding. When the driven roller rotates, it drives the first gear via a single-sided toothed synchronous belt. The first gear, in turn, drives the second gear, which, in turn, drives the third gear via the same belt. With the cooperation of the support plate, slider, slide block, arc block, toothed plate, sliding plate, and frame, the sleeve can move up, down, left, and right, allowing the scraper to scrape the material to the top left end of the conveyor seat. When the scraper approaches the conveyor belt, the electric telescopic rod extends, causing the clamping plate to leave the slot. The cooperation of the spring and the sleeve allows the scraper to extend and retract, preventing the horizontal movement of the scraper from being obstructed when the height of the conveyor belt exceeds the height of the top left end of the conveyor seat. This ensures that the material is smoothly scraped onto the conveyor belt. Attached Figure Description
