DETAILED DESCRIPTION

[0021] The preferred embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0022] As Figures 1-4As shown, a feeding device for recycled automotive castings includes a receiving box 1, which is movably mounted above a base plate 2. A protective cover 3 is rotatably connected to the top surface of the receiving box 1 via a hinge. The top surface of the protective cover 3 has a discharge port 4 and a spheroidizing agent discharge hole 5. A fixing frame 6 is detachably mounted inside the receiving box 1, and a screen 7 is fixed inside the fixing frame 6. Two mounting slots 8 are respectively opened on the left and right sides of the inner wall of the receiving box 1. Mounting plates 9 are respectively fixed on the left and right sides of the outer wall of the fixing frame 6. Fixing grooves 10 are provided on the outer side of the loading plate 9. Fixing holes 11 are provided on the left and right sides of the outer wall of the receiving box 1. Fixing shafts 12 are slidably inserted into the two fixing holes 11. The two fixing shafts 12 are slidably inserted into the two fixing grooves 10. Stop blocks 13 are fixed to the outer ends of the two fixing shafts 12. Springs 14 are fixed to the left and right sides of the outer wall of the receiving box 1. The two springs 14 are respectively wrapped around the two fixing shafts 12. The outer ends of the two springs 14 are respectively fixedly connected to the inner sides of the two stop blocks 13.

[0023] In use, the operator first puts the material into the protective cover 3 through the discharge port 4, and then puts the low-silicon spheroidizing agent into the protective cover 3 through the spheroidizing agent discharge hole 5. By using the low-silicon spheroidizing agent, the silicon increase is reduced by 0.1% to 0.2%, improving the utilization rate of recycled materials. After the material falls into the protective cover 3, it comes into contact with the screen 7 and is separated by the screen 7. Larger materials stay on the surface of the screen 7, while smaller materials fall into the receiving box 1. When the operator needs to disassemble the screen 7, first flip the protective cover 3 open, and then turn the baffle 13 outward. Pulling the fixed shaft 12 away from the inside of the fixed groove 10 will cause the spring 14 to be in a stretched state, allowing the fixed frame 6 and screen 7 to be removed. Conversely, when the worker needs to install the screen 7, first pull the stop block 13 outward, then place the fixed frame 6 and screen 7 into the receiving box 1 from top to bottom, so that the mounting plate 9 slides into the mounting groove 8. Then release the stop block 13, and the fixed shaft 12 will automatically reset through the spring 14, allowing the fixed shaft 12 to slide into the fixed groove 10, thus completing the installation of the screen 7.

[0024] The mounting plate 9, fixed shaft 12, stop block 13, and spring 14 facilitate the disassembly and assembly of the fixed frame 6 and screen 7 by the staff without the need for additional tools, saving time and effort, improving the convenience of operation, and making the maintenance of screen 7 easier.

[0025] like Figures 1-4 As shown, two positioning blocks 15 are fixed on the left and right sides of the outer wall of the fixed frame 6, and two positioning grooves 16 are opened on the left and right sides of the inner wall of the receiving box 1, respectively, and the two positioning grooves 16 respectively position the two positioning blocks 15.

[0026] In use, the positioning block 15 and the positioning groove 16 facilitate the positioning of the fixing frame 6, ensuring the accurate installation position of the fixing frame 6 and avoiding misplacement or deviation during installation.

[0027] As shown in Figures 1-4 The bottom surface of the fixing frame 6 is fixed with a vibration motor 17, and the top surface of the bottom plate 2 is fixed with a hydraulic push rod 18, one end of the telescopic rod of the hydraulic push rod 18 is fixedly connected with the bottom surface of the receiving box 1.

[0028] In use, after starting the vibration motor 17, the fixing frame 6 and the screen 7 start to vibrate, which promotes the flow and separation of materials on the screen 7, making the screening process more efficient and thorough. By starting the hydraulic push rod 18, the receiving box 1 can be adjusted in height, and the height of the receiving box 1 and the screen 7 can be adjusted, which can be flexibly adjusted according to actual needs.

[0029] As shown in Figures 1-4 The top surface of the bottom plate 2 is fixed with a plurality of limiting sleeves 19, the inner part of the plurality of limiting sleeves 19 is respectively slidably inserted with a limiting column 20, the top end of the plurality of limiting columns 20 is respectively fixedly connected with the bottom surface of the receiving box 1, and the outer wall left side and right side of the protective cover 3 is respectively fixed with a handle 21.

[0030] In use, the limiting sleeve 19 and the limiting column 20 facilitate the limiting of the receiving box 1, prevent the receiving box 1 from deviating, and improve the stability of the receiving box 1 during lifting. The staff can easily and quickly open the protective cover 3 by grabbing the handle 21, which is convenient for operation and maintenance.

[0031] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
