[0002] In industries such as casting, building materials, glass manufacturing, and composite materials, sand mixing is a key process that mixes manufactured sand, natural sand, and binders (such as resin, clay, water glass, etc.) in a certain proportion to form molding sand with certain uniformity and processing properties. Sand mixing equipment mostly adopts single-shaft spiral agitation, twin-shaft paddle agitation, or simple drum mixing.

[0003] When sand enters the hopper of the sand mixing equipment, it is poured in directly, which can easily cause it to accumulate inside the equipment. During mixing, the excessive amount of sand in some areas will increase the damping at the accumulation point, affecting the mixing efficiency and increasing energy consumption.

[0004] Therefore, a low-damping, energy-saving planetary sand mixing device is proposed to solve the problems mentioned above. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] Please see Figure 1 - Figure 6 The low-damping energy-saving planetary sand mixing device in this embodiment includes a frame 1, a mixing chamber 2 fixedly connected inside the frame 1, a planetary geared motor 3 fixedly connected to one side of the frame 1, a mixing paddle 4 rotatably connected inside the mixing chamber 2 via bearings, a discharge port 5 at the bottom of the mixing chamber 2, and a material distribution mechanism at the top of the mixing chamber 2. The material distribution mechanism includes a support 6, a hopper 7, a material distribution port 8, and an arc surface 9. The support 6 is fixedly connected to the back of the mixing chamber 2, the hopper 7 is fixedly connected to one end of the support 6, the material distribution port 8 is located at the bottom of the hopper 7, the arc surface 9 is located inside the hopper 7, and a screen 10 is provided at the top port of the mixing chamber 2 for passage.

[0021] During use, the manufactured sand and natural sand to be mixed enter the silo 7 and are dispersed through the distribution port 8 inside the silo 7. After being filtered through the screen 10, they enter the mixing chamber 2 for stirring and mixing. The distribution port 8 is designed to prevent the sand from piling up in the middle during filtration or mixing, which would reduce the screening and mixing efficiency. By avoiding piling up, the damping during mixing is reduced, the mixing efficiency is improved, and energy saving is achieved.

[0022] Please see Figure 1 - Figure 6 The output end of the planetary geared motor 3 is fixedly connected to one end of the mixing paddle 4, and the material distribution ports 8 are evenly distributed at the bottom of the hopper 7.

[0023] To facilitate sand screening, a transmission mechanism is provided on the outside of the frame 1. The transmission mechanism includes a guide frame 11, a slider 12, a connecting rod 13, a chute 14, a drive motor 15, a turntable 16, and a first fixed column 17. The guide frame 11 is fixedly connected to both sides of the frame 1, the slider 12 is slidably connected inside the guide frame 11, the connecting rod 13 is fixedly connected to the outside of the slider 12, the chute 14 is opened through the outside of the connecting rod 13, the drive motor 15 is fixedly connected to the outside of the mixing chamber 2, the turntable 16 is fixedly connected to the output end of the drive motor 15, and the first fixed column 17 is fixedly connected to the top of the turntable 16.

[0024] The drive motor 15 drives the turntable 16 to rotate. With the setting of the first fixed column 17 and the slide 14, the connecting rod 13 and the slider 12 are driven to slide back and forth, thereby achieving the effect of screening sand. This avoids large sand from entering the mixing chamber 2 and colliding with the mixing paddle 4, which could damage the mixing paddle 4. This provides better protection for the equipment and ensures that the mixed sand is more uniform.

[0025] Please see Figure 1 - Figure 6 The first fixed post 17 is set inside the slide groove 14. The inner wall of the slide groove 14 is in contact with the outer wall of the first fixed post 17. The outer side of the slider 12 is provided with a groove. The inner wall of the groove is in contact with the outer wall of the guide frame 11. A limit groove is provided at the connection between the guide frame 11 and the mixing chamber 2. The inner wall of the limit groove is in contact with the outer wall of the slider 12.

[0026] To facilitate the replacement and cleaning of the screen 10, a second pin 23 is fixedly connected to the bottom of the screen frame of the screen 10. A through groove 18 is provided on the outer side of the slider 12. A second fixing post 19 is fixed on both sides of the slider 12. A buckle 20 is inserted through the through groove 18. A first pin 21 is fixedly connected to the inner side of the buckle 20. A clamping plate 22 is fixedly connected to the outer side of the buckle 20.

[0027] When installing the screen 10, the second pin 23 is inserted into the slider 12, and then the buckle 20 is slidably engaged inside the through groove 18. At this time, the first pin 21 slides through and inserts into the second pin 23 to install and fix the screen 10. The clamping plate 22 is engaged with the second fixing post 19, thereby fixing the buckle 20 a second time, further ensuring the stable installation of the screen 10. The quick installation setting of the screen 10 makes it easy to disassemble and clean it or replace it with a screen 10 of different aperture, making the operation more convenient.

[0028] Please see Figure 1 - Figure 6The second pin 23 is slidably inserted into the inside of the slider 12, and the first pin 21 is slidably inserted through the second pin 23.

[0029] The working principle of the above embodiments is as follows: When in use, the manufactured sand and natural sand to be mixed enter the silo 7 and are dispersed through the distribution port 8 inside the silo 7. After being filtered through the screen 10, they enter the mixing chamber 2 for stirring and mixing. The distribution port 8 is designed to prevent the sand from piling up in the middle during filtration or mixing, which would reduce the screening and mixing efficiency. By avoiding piling up, the damping during mixing is reduced, and the mixing efficiency is improved. The drive motor 15 drives the turntable 16 to rotate. With the setting of the first fixed column 17 and the slide 14, the connecting rod 13 and the slider 12 are driven to slide back and forth, thereby achieving the effect of screening sand. This avoids large sand from entering the mixing chamber 2 and colliding with the mixing paddle 4, which would damage the mixing paddle 4. This provides better protection for the equipment and ensures that the mixed sand is more uniform. When installing the screen 10, the second pin 23 is inserted into the slider 12, and then the buckle 20 is slidably engaged inside the through groove 18. At this time, the first pin 21 slides through and inserts into the second pin 23 to install and fix the screen 10. The clamping plate 22 is engaged with the second fixing post 19, thereby fixing the buckle 20 a second time, further ensuring the stable installation of the screen 10. The quick installation setting of the screen 10 makes it easy to disassemble and clean it or replace it with a screen 10 of different aperture, making the operation more convenient.

[0030] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
