DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] Please refer to Figures 1 to 4, in the embodiment of the present utility model, a ladle paving machine includes a semi-finished product bin 2, a belt conveyor 4, a slow feeding pipe 9 and a ladle 11. The belt conveyor 4 is arranged at the discharge port of the semi-finished product bin 2. The semi-finished products output from the semi-finished product bin 2 are sent to a high position through the belt conveyor 4. A slow feeding pipe 9 capable of receiving semi-finished products is arranged at the high position end of the belt conveyor 4. The ladle 11 is a container for containing liquid molten metal. By pouring the semi-finished products of the liquid molten metal into the bottom of the ladle 11, it can effectively prevent the molten iron from scouring the bottom wall of the ladle 11 and play a protective role for the ladle. The design and innovation of the paving machine is to utilize the feeding equipment and the belt conveyor 4. The feeding equipment can be a vibrating feeding device to perform the paving operation for the ladle 11 at a fixed point. The start and stop of the belt conveyor 4 and the vibrating feeder are controlled by using a wireless remote control handle, which is both convenient and safe. The use of the paving machine reduces the costs such as forklift labor and fuel, avoids the safety risks existing in forklift operation, and solves the problem of the molten iron scouring the inner lining of the bottom wall of the ladle 11.
[0022] In a preferred embodiment, a high-position bin support 1 is arranged at the bottom of the semi-finished product bin 2, and a feeder 3 is arranged at the discharge port of the semi-finished product bin 2. The semi-finished products are evenly output to the belt conveyor 4 through the feeder 3. The feeder 3 can be a vibrating feeding device, and its main function is to keep the feeding speed and the semi-finished products uniform. Only the semi-finished products lifted by the belt conveyor 4 can maintain a uniform speed and quantity.
[0023] In a preferred embodiment, a strengthening support 6 is erected at the bottom of the belt conveyor 4, and a lifting support 5 in contact with the ground is arranged outside the strengthening support 6. The belt conveyor 4 is arranged obliquely. The main function of the belt conveyor 4 is to lift the semi-finished products. Because the ladle 11 has a certain height and the ladle 11 has only one inlet and outlet opening, it is necessary to lift the semi-finished products to a height higher than the ladle 11 before filling them in.
[0024] In a preferred embodiment, a terminal support 7 is arranged outside the slow feeding pipe 9 through a connector 8;
[0025] The connector 8 includes a mounting cross beam 801, an inclined angle bracket 802, a pipe seat 803 and a pipe clamp 804. The mounting cross beam 801 is fixed on the terminal support 7 by bolts. Two inclined angle brackets 802 are fixed on the mounting cross beam 801 by bolts. A pipe seat 803 is installed between the inclined angle brackets 802. The pipe seat 803 and the pipe clamp 804 fix and hold the slow feeding pipe 9 by bolts. The fixed support of the slow feeding pipe 9 is crucial because it needs to extend a certain distance. The semi-finished products have a high density and a large weight. The supporting equipment of the slow feeding pipe 9 needs to have good stability and supportability. The inclined angle bracket 802 can provide good supportability and stability for it, and has the advantages of being disassemblable and replaceable.
[0026] In a preferred embodiment, the material buffer pipe 9 is composed of a material receiving hopper 901, a material sliding pipe 902 and a vertical pipe 903. The material receiving hopper 901 is installed at the top of the material sliding pipe 902, and the vertical pipe 903 is installed at the bottom. The material receiving hopper 901 is located at the discharging end of the belt conveyor 4. The material sliding pipe 902 is inclined and extends outward for a distance of two to four meters, which is greater than the radius of the ladle 11. The main function of the material buffer pipe 9 is to convey semi-finished products and control the feeding of semi-finished products. The ladle 11 is lifted by a special lifting tool 10. In order to prevent the lifting tool 10 from colliding with the material buffer pipe 9, the material buffer pipe 9 needs to be set inclined. The ladle 11 needs to be sleeved outside the vertical pipe 903 from the bottom. Therefore, a pit 12 is arranged below the vertical pipe 903 to increase the moving space of the ladle 11.
[0027] In a preferred embodiment, a material buffer slide plate 904 is arranged in the vertical pipe 903. The material buffer slide plate 904 is inclined, and the inclination angle is greater than 20 degrees. A downward sliding opening is arranged at the inclined bottom end of the material buffer slide plate 904, and the area of the downward sliding opening is greater than the conveying speed of the semi-finished product. The vertical pipe 903 can send the semi-finished product to the bottom of the ladle 11. If the drop of the semi-finished product is too large, it will impact the bottom wall lining of the ladle 11, and the service life of the lining of the ladle 11 will also be reduced. Therefore, the material buffer slide plate 904 is arranged in the vertical pipe 903, and the semi-finished product slides down on the material buffer slide plate 904 to avoid impact caused by vertical falling.
[0028] It should be noted that the above embodiments all belong to the same inventive concept of the utility model. The descriptions of the embodiments have their own emphases. For the parts not described in detail in individual embodiments, reference can be made to the descriptions in other embodiments.
[0029] The above embodiments only represent the implementation modes of the present utility model. The descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, without departing from the inventive concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
