Description

Technical Field

[0001] The present invention relates to the technical field of furnace charging, and in particular to a furnace charging device. Background Art

[0002] During the casting production process, it is necessary to add metal raw materials to the casting furnace from time to time. The casting furnace feed port is at the top of the furnace body. In the process of adding materials into the furnace, it is difficult to control the amount of addition. In the process of conveying the materials, there is no positioning and clamping function for the materials. The materials may fall directly into the furnace, causing the slurry to splash, affecting production safety. Adding too much material at one time may cause the slurry to splash. Summary of the Invention

[0003] In order to solve the technical problems existing in the background technology, the present invention proposes a furnace charging device.

[0004] The present invention proposes a furnace loading device, which includes a strip conveyor plate, the top of the strip conveyor is rotatably connected to a tipping bucket, the end of the strip conveyor is installed with a mounting platform, the mounting platform is installed with a cylinder, the top of the cylinder is fixedly connected with a top plate, and the side wall of the strip conveyor close to one end of the mounting platform is installed with a slide plate, the slide plate transports the material into the strip conveyor, and the top plate pushes the material toward the tipping bucket, side plates are vertically installed on both sides of the upper surface of the strip conveyor, the two groups of side plates are parallel to each other, and the inner side walls of the two groups of side plates are installed with conveyor belts, the belt surfaces of the two groups of conveyor belts are opposite, and a motor is installed at the bottom of the strip conveyor, and one end of the motor is connected to the tipping bucket through a rotating shaft.

[0005] Preferably, the slide plate is inclined toward the strip conveying path.

[0006] Preferably, limit plates are vertically installed on both sides of the slide, a number of rollers are rotatably connected between the two groups of limit plates, and a baffle is installed on the side of the top plate close to the slide.

[0007] Preferably, the two groups of side plates are slidably connected to the strip conveyor, and the spacing between the two groups of side plates can be adjusted on the strip conveyor.

[0008] Preferably, two groups of slide grooves are horizontally opened on the upper surface of the strip conveyor, and the bottoms of the two groups of side plates are connected with card keys, and the card keys are engaged with the corresponding slide grooves. The outer side walls of the side plates are provided with guide slopes, and the thickness of the side plates gradually narrows from top to bottom. Two groups of telescopic rods are vertically installed on the top of the strip conveyor, and top rollers are installed on the tops of the two groups of telescopic rods. The two groups of top rollers are respectively located below the guide slopes of the side plates, and elastic members are provided in the slide grooves;

[0009] When the two groups of telescopic rods are pushed upward, the two groups of side plates approach each other, and when the two groups of telescopic rods are retracted, the elastic members separate the two groups of side plates.

[0013] In the present invention, a furnace loading device is proposed. The strip conveyor extends the tipping bucket into the inner cavity of the furnace. The slide guides the material to be melted to the strip conveyor. The top plate is driven forward by the cylinder. The strip conveyor is clamped and transported forward by the conveyor belts on both sides to push the material into the tipping bucket. The tipping bucket rotates to drop the material into the furnace. The roller can convert sliding friction into rolling friction. While the top plate pushes the material into the strip conveyor, the baffle blocks the material on the slide from continuing to load, and can also control the loading amount. When the top plate retreats, the loading channel on the slide The road opens and the material enters the strip conveyor. When the two sets of telescopic rods are lifted up and the top roller pushes upward, the distance between the two sets of side plates decreases and moves closer under the guidance of the guide slope. The two sets of conveyor belts clamp the material and convey it forward. The distance between the two sets of conveyor belts can be adjusted according to the amount of material, and the material can be clamped and conveyed during the conveying process. Compared with traditional conveyor belts, when the inclination angle of the strip conveyor is too large, to avoid slipping, the motor drives the tipping bucket to rotate through the rotating shaft. When the material slips from the tipping bucket, the buffer plate acts as a barrier to prevent the molten slurry from splashing when it falls into the furnace.

[0014] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The strip conveyor 1 extends the tipping bucket 4 into the inner cavity of the furnace, and the slide 2 guides the material to be melted to the strip conveyor 1. The cylinder 301 drives the top plate 302 to push forward, and the conveyor belts 102 on both sides clamp the strip conveyor 1 and convey it forward, pushing the material into the tipping bucket 4. The tipping bucket 4 rotates and drops the material into the furnace.

[0025] Preferably, the slide plate 2 is inclined toward the strip conveyor 1 , and gradually guides the material into the strip conveyor 1 under the action of gravity.

[0026] Preferably, limit plates are vertically installed on both sides of the slide 2, and a number of rollers 201 are rotatably connected between the two groups of limit plates. A baffle 303 is installed on the side of the top plate 302 close to the slide 2. The roller 201 can convert sliding friction into rolling friction. When the top plate 302 pushes the material into the strip conveyor 1, the baffle 303 blocks the material on the slide 2 from continuing to be loaded, and can also control the loading amount. When the top plate 302 retracts, the loading channel on the slide 2 opens, and the material enters the strip conveyor 1.

[0027] Preferably, the two groups of side plates 101 are slidably connected to the strip conveyor 1 , and the spacing between the two groups of side plates 101 can be adjusted on the strip conveyor 1 .
