[0002] A sand mixer is a casting equipment that uniformly mixes molding sand, binders, additives, and other materials, and effectively coats the surface of sand particles with binders. It is widely used in casting, building materials processing and other fields. During the use of a sand mixer, materials tend to adhere to the inner wall of the mixer and the mixing components. If not cleaned in time, the residual materials will gradually clump and harden, which will not only affect the mixing quality of subsequent materials, but may also cause the mixing components to jam, accelerate equipment wear, and reduce the service life of the equipment.

A discharge pipe 8 is connected to the lower surface of the sand mixing tank 1, and a control switch 9 is provided on the outer surface of the discharge pipe 8. By setting the discharge pipe 8 and the control switch 9, the discharge of the mixed material in the sand mixing tank 1 can be controlled, avoiding leakage or incomplete discharge during the discharge process, and improving the convenience and controllability of the discharge operation. A support frame 6 is fixedly connected to the upper surface of the sand mixing tank 1, and a servo motor 4 is fixedly installed on the upper surface of the support frame 6. The servo motor 4 is connected to... Controlled by an external controller, the support frame 6 provides stable mounting support for the servo motor 4, ensuring the stability of the servo motor 4 during operation. The output end of the servo motor 4 passes through the upper surface of the support frame 6 and is fixedly connected to the stirring shaft 7. The bottom end of the stirring shaft 7 is rotatably connected to the inner wall of the sand mixing tank 1. The outer surface of the stirring shaft 7 is fixedly fitted with stirring components 5 at equal intervals. The servo motor 4 drives the stirring shaft 7 and the equally spaced stirring components 5 to rotate, which can uniformly and efficiently stir the material in the sand mixing tank 1, ensuring the mixing quality of the material and meeting the production and processing requirements.
[0020] The upper surface of the support frame 6 is provided with a spray component 3 and a cleaning component 2 respectively. The spray component 3 and the cleaning component 2 are integrated and installed on the support frame 6, eliminating the need for additional installation structures, simplifying the overall layout of the equipment, and facilitating unified maintenance of the two components, thereby improving the convenience of using the equipment.
[0021] The cleaning component 2 includes a mounting frame 21, which is fixedly mounted on the upper surface of the support frame 6. A cylinder 22 is fixedly mounted on the upper surface of the mounting frame 21. The mounting frame 21 provides a stable mounting base for the cylinder 22, ensuring the structural stability of the cylinder 22 during operation. The cylinder 22 is powered by an external air source to start operation, and the output end of the cylinder 22 passes through the upper surface of the mounting frame 21 and is fixedly connected to a connecting plate 23. The cylinder 22 drives the connecting plate 23 to move up and down, which can drive the subsequent cleaning components to achieve reciprocating cleaning action, providing power support for automatic cleaning, which is more efficient than manual cleaning.
[0022] A connecting rod 24 is fixedly connected to the lower surface of the connecting plate 23, and a cleaning scraper 25 is movably installed on the lower surface of the connecting rod 24. The connecting plate 23 and the connecting rod 24 form a transmission connection structure, which can stably transmit the power of the cylinder 22 to the cleaning scraper 25. The cleaning scraper 25 adopts a movable installation method, which is convenient for subsequent disassembly and replacement, reducing equipment maintenance costs. A plug rod 26 is fixedly connected to the upper surface of the cleaning scraper 25. The plug rod 26 is movably inserted into the lower surface of the connecting rod 24. A stainless steel bolt 27 is threaded between the plug rod 26 and the connecting rod 24. Through the movable insertion and engagement of the plug rod 26 and the connecting rod 24, combined with the threaded fixation of the stainless steel bolt 27, the cleaning scraper 25 and the connecting rod 24 are detachably fixedly connected. The installation and disassembly are convenient, and the stainless steel bolt 27 has good corrosion resistance, which can extend the service life of the connection structure.
[0023] The cleaning scraper 25 has an annular cross-sectional shape. The outer surface of the cleaning scraper 25 slides against the inner wall of the sand mixing tank 1. The cleaning scraper 25 adopts an annular cross-sectional design, and the outer surface slides against the inner wall of the sand mixing tank 1. When the cylinder 22 drives it to move up and down, it can scrape and clean the inner wall of the sand mixing tank 1, effectively removing the mortar adhering to the inner wall. Compared with manual cleaning, it is more convenient and efficient, and significantly improves cleaning efficiency.
[0024] The spray assembly 3 includes a water tank 37, which is fixedly installed on the upper surface of the support frame 6. The water tank 37 can store the water required for cleaning, providing continuous water supply for spray cleaning. A water inlet 38 is provided on the upper surface of the water tank 37 for timely water replenishment. A sealing plug 39 is movably engaged with the inner wall of the water inlet 38, sealing the water inlet 38 to prevent water leakage or external contamination within the water tank 37. A water pump 31 is connected to one side of the water tank 37. A water pump 32 is connected to one end of the water pump 31 and is fixedly installed on the upper surface of the support frame 6. The water pump 32 is fixed on the support frame 6, which is stable and has low vibration during operation. A water delivery pipe 33 is connected to the output end of the water pump 32. The water pump 32 draws water from the water tank 37 through the water pump 31 and delivers the high-pressure water flow to the subsequent spraying components through the water delivery pipe 33, providing sufficient water pressure for spraying and cleaning and ensuring the cleaning effect.
[0025] One end of the water supply pipe 33 passes through the support frame 6 and is connected to a spray pipe 36. The outer surface of the spray pipe 36 is connected to a first spray head 35 in a ring array. The first spray head 35 is inclined and faces the inner wall of the sand mixing tank 1. The spray pipe 36 provides a mounting carrier for the first spray head 35. The ring array of first spray heads 35, together with their inclined orientation towards the inner wall of the sand mixing tank 1, can perform high-pressure spray rinsing on the inner wall of the sand mixing tank 1. This, combined with the scraping cleaning of the cleaning scraper 25, further improves the cleaning effect of the inner wall of the sand mixing tank 1 and avoids mortar residue.
[0026] The spray pipe 36 is fixedly installed on the lower surface of the support frame 6. The lower surface of the spray pipe 36 is connected to a plurality of second spray heads 34 for use with the agitator 5. The second spray heads 34 are specially designed to work with the agitator 5 and can perform high-pressure spray rinsing on the outer surface of the agitator 5 on the agitator shaft 7, effectively removing material residues adhering to the surface of the agitator 5, ensuring that the agitator 5's mixing effect is not affected. In addition, the second spray heads 34 can also perform high-pressure rinsing on the lower inner wall of the sand mixing tank 1. At the same time, they work together with the first spray head 35 to achieve comprehensive cleaning of the inside of the sand mixing tank 1 and the agitator components, optimizing the overall cleaning effect of the equipment.
[0027] Working principle: First, start the servo motor 4. The output end of the servo motor 4 drives the stirring shaft 7 to rotate around the inner wall of the mixing tank 1. The stirring parts 5, which are fixedly sleeved at equal intervals on the outer surface of the stirring shaft 7, rotate synchronously with the stirring shaft 7, so as to carry out all-round and uniform mixing of the materials to be mixed in the mixing tank 1 until the materials reach the preset mixing effect.
[0028] After the sand mixing is completed, turn on the control switch 9 on the outer surface of the discharge pipe 8, and the mixed material will be discharged through the discharge pipe 8, thus completing the sand mixing operation.
[0029] Automatic cleaning operation, mechanical scraping cleaning, the cylinder 22 in the cleaning component 2 is activated. The cylinder 22 is fixedly installed on the mounting bracket 21. The output end of the cylinder 22 drives the connecting plate 23 to move up and down reciprocally. The connecting plate 23 drives the cleaning scraper 25 to move up and down synchronously through the connecting rod 24. Since the cleaning scraper 25 has an annular cross section and its outer surface slides and adheres to the inner wall of the sand mixing tank 1, it can completely scrape off the material residue adhering to the inner wall of the sand mixing tank 1 during the movement.
[0030] The cleaning scraper 25 is movably connected to the connecting rod 24 via the insert rod 26 and is fixed by stainless steel bolts 27, ensuring that the cleaning scraper 25 and the connecting rod 24 are firmly connected during the scraping process, preventing them from falling off and affecting the cleaning effect. At the same time, the movable cleaning scraper 25 is also easy to maintain and replace.
[0031] High-pressure spray cleaning is performed simultaneously with the water pump 32 in the spray assembly 3. The water pump 32 draws clean water from the water storage tank 37 through the water pipe 31. The water inlet 38 on the upper surface of the water storage tank 37 can be used to replenish the water source. The sealing plug 39 ensures that the water storage tank 37 is sealed and leak-proof. The water pump 32 delivers high-pressure water through the water delivery pipe 33 to the spray pipe 36.
[0032] The first spray head 35, which is connected in a ring array on the outer surface of the spray pipe 36, is tilted toward the inner wall of the sand mixing tank 1. After the high-pressure water flows through the first spray head 35 and sprays out, it performs high-pressure rinsing on the inner wall of the sand mixing tank 1. Combined with the scraping action of the cleaning scraper 25, it thoroughly removes the residual material on the inner wall.
[0033] At the same time, multiple second spray heads 34 connected to the lower surface of the spray pipe 36 are specifically aimed at the agitator 5, and the high-pressure water jets sprayed out wash the surface of the rotating agitator 5 to remove the material residue adhering to the agitator 5.
[0034] In addition, the second spray head 34 can perform high-pressure rinsing on the lower inner wall of the sand mixing tank 1.
[0035] Wastewater and residual material debris generated during cleaning are discharged from the mixing tank 1 through the discharge pipe 8 and the control switch 9 is turned on, thus completing the comprehensive cleaning operation.
[0036] The mechanical scraping of the cleaning component 2 and the high-pressure spraying of the spraying component 3 work together. The cleaning scraper 25 first scrapes away a large area of stubborn residue on the inner wall, and then the first spray head 35 and the second spray head 34 perform high-pressure rinsing to ensure that there is no material residue on the inner wall of the sand mixing tank 1 and the mixing component 5, thus achieving the self-cleaning function.
[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
