The top cover seals the opening of the receiving tank body 10, and the material pipe 11 is fixedly installed on the top cover;

[0029] like Figure 2 , Figure 3 and Figure 4As shown, the cleaning assembly is arranged in the cavity of the receiving tank body 10 for cleaning the inner wall and the bottom impurities of the receiving tank body 10. The cleaning assembly includes a rotating shaft 20, a cross bar 21, a vertical bar 22 and a scraper 23. The rotating shaft 20 is rotatably connected to the receiving tank body 10. The top of the receiving tank body 10 is provided with a motor-driven rotating shaft 20, the cross bar 21 is fixedly connected to the rotating shaft 20, the vertical bar 22 is fixedly connected to the cross bar 21, the scraper 23 is detachably mounted on one side of the vertical bar 22 and contacts the inner wall of the receiving tank body 10, and the cross bar 21 is fixedly connected to the vertical bar 22. A scraper is fixedly installed at the bottom, and two groups of cross bars 21 are symmetrically arranged on the wall of the rotating shaft 20. The two cross bars 21 form a group. The two ends of the vertical rod 22 are fixedly connected to the two cross bars 21 of the same group respectively. The bottoms of the two lower cross bars 21 are fixedly connected to the same scraper. The scraper extends obliquely toward the bottom surface of the receiving tank body 10. The bottom surface of the receiving tank body 10 is provided with a slag discharge window. The bottom of the receiving tank body 10 is bolted with a sealing plate, which blocks and seals the slag discharge window. In this solution, the end of the output shaft of the motor forms The receiving tank body 10 is a rectangular columnar structure. The top of the rotating shaft 20 is provided with a rectangular notch. The motor output shaft is inserted into the notch. A bearing is installed at the bottom of the receiving tank body 10. The rotating shaft 20 is fixedly connected to the inner ring of the bearing. The rotating shaft 20 is driven by the motor to rotate. The rotating shaft 20 drives the horizontal rod 21 and the vertical rod 22 to move in a circle. The scraper and the scraper body 23 scrape the inner bottom surface and the side wall of the receiving tank body 10 respectively to achieve cleaning. The arc-shaped scraper body 23 itself has a certain elastic deformation ability, which can ensure the contact with the inner wall of the receiving tank body 10. With full contact, the inclined scraper can tightly contact the inner bottom surface of the receiving tank body 10, thereby ensuring the cleaning effect of the inner wall of the receiving tank body 10 and reducing the workload of manual cleaning. The simple structure is convenient for later maintenance and for the development and implementation of the cleaning work of the receiving tank body 10. The slag discharge window is close to the inner wall of the receiving tank body 10. Under the expulsion action of the scraper, it is easy to squeeze impurities toward the slag discharge window to achieve slag discharge. A sealing gasket is provided between the sealing plate and the receiving tank body 10 to ensure the sealing effect, which will not be elaborated here.

[0030] like Figure 4 and Figure 5 As shown, the cleaning component also includes a resistance plate 24, which is fixedly connected to the vertical rod 22. The resistance plate 24 can push the scraper 23 to resist the inner wall of the receiving tank body 10. The scraper 23 and the resistance plate 24 are both arc-shaped plate structures. One end of the resistance plate 24 is fixedly connected to the vertical rod 22, and the other end of the resistance plate 24 resists the concave surface of the scraper body 23.

The slot 25 is adapted to the protrusion 26. The height of the slot 25 is less than the height of the vertical rod 22. Specifically, the protrusion 26 is integrally formed with the scraping body 23. The scraping body 23 is installed by inserting the protrusion 26 into the slot 25. The top of the vertical rod 22 can be installed with a limit plate by bolts, and the protrusion 26 is pressed into the slot 25 by the limit plate, which is convenient for disassembly and assembly during the later maintenance process.

[0032] The working principle of the utility model is as follows: the rotating shaft 20 is driven to rotate by the motor, and the rotating shaft 20 drives the horizontal rod 21 and the vertical rod 22 to move in a circular motion, and the inner bottom surface and the side wall of the receiving tank body 10 are scraped by the scraper and the scraper body 23 respectively to achieve cleaning. The arc-shaped scraper body 23 itself has a certain elastic deformation ability, which can ensure full contact with the inner wall of the receiving tank body 10, and cooperates with the arc-shaped resistance plate 24 to resist the inner concave surface of the scraper body 23, that is, the inner circumferential surface of the scraper body 23. The resistance plate 24 has a certain elastic potential energy, which can ensure the squeezing and pushing force on the scraper body 23. The protrusion 26 and the scraper body 23 are integrally formed, and the installation of the scraper body 23 is achieved by inserting the protrusion 26 into the slot 25. The top of the vertical rod 22 can be installed with a limit plate by bolts, and the protrusion 26 is pressed tightly in the slot 25 by the limit plate, which is convenient for disassembly and assembly during the later maintenance process.
