[0013] By adopting the above technical solution, the middle part of the screw conveyor is supported by columns and base, thereby providing support for the middle part of the screw conveyor.

[0014] A further feature of this invention is that a first pulley is fixedly installed at the bottom of the base, and a second pulley is fixedly installed at the bottom of the counterweight box.

[0015] By adopting the above technical solution, after feeding is completed, the second connecting plate is removed from the top of the feed pipe, and the base and counterweight box are moved by the first pulley and the second pulley.

[0016] A further feature of this invention is that a support rod is fixedly connected to the bottom of the sand mixer, and a support plate is fixedly connected to the bottom of the support rod.

[0017] By adopting the above technical solution, the bottom of the sand mixer is supported by support rods and support plates.

[0018] A further feature of this invention is that the number of support rods is four, the number of support disks is four, and the four support rods and support disks are distributed in a circular array.

[0019] By adopting the above technical solution, four support rods and four support discs are distributed around the bottom of the sand mixer, improving the stability of the support.

[0020] A further feature of this invention is that each of the four support plates has a support leg fixedly connected to both sides, and the support leg has a bolt threaded inside.

[0021] By adopting the above technical solution, the bolts are threaded into the inside of the support legs, and the bolts extend into the base surface, thereby fixing the entire sand mixer.

[0022] A further feature of this invention is that the number of vibration motors is two, and the two vibration motors are symmetrically distributed on both sides of the feed pipe.

[0023] By adopting the above technical solution, two vibration motors are distributed on the left and right sides of the feed pipe. The vibration effect is improved by setting up two vibration motors.

[0024] A further feature of this invention is that the bottom of the sand mixer is provided with a discharge pipe, and the inside of the discharge pipe is provided with a gate.

[0025] By adopting the above technical solution, after the coated sand is mixed inside the sand mixer, the coated sand is discharged through the discharge pipe.

[0026] The beneficial effects of this utility model are:

[0027] This device reduces the difficulty of feeding and improves the feeding efficiency by conveying the coated sand from low to high. It can also prevent blockages during the feeding process. After feeding is completed, the feeding mechanism of this device can be separated from the sand mixer, which improves the ease of use. Attached Figure Description

The second connecting disc 8 is fixed to the top of the feed pipe 7 via the screw pin 9. The screw conveyor 5 is inclined and set outside the sand mixer 1. After the coated sand enters the screw conveyor 5, it is fed from low to high, thus creating a feeding effect of coated sand from low to high. The end of the screw conveyor 5 is connected to the feed pipe via a gauze layer 10, which can prevent leakage of coated sand. During the feeding process, the vibrating motor 12 provides a vibration effect, causing the coated sand inside the feed pipe to shake, thus preventing leakage of the feed pipe. To address the issue of feed blockage, this device reduces the difficulty of feeding and improves feeding efficiency by conveying the coated sand from low to high. It also prevents blockages during the feeding process. The counterweight 13 is installed inside the counterweight box 2 through a cavity, increasing the overall weight of the counterweight box 2 and improving the support stability of the screw conveyor 5. The coated sand enters the screw conveyor 5 through the trumpet-shaped feed hopper 14. The large opening of the feed hopper 14 prevents leakage of the coated sand during the feeding process. Two vibrating motors 12 are distributed on the left and right sides of the feed pipe 7, which enhances the vibration effect.

The bottom of the sand mixer 1 is provided with a discharge pipe, and the inside of the discharge pipe is provided with a gate.

[0045] Specifically, the bottom of the sand mixer 1 is supported by support rods 20 and support plates 21. Four support rods 20 and four support plates 21 are distributed around the bottom of the sand mixer 1 to improve support stability. Bolts 23 are threaded into the inside of the support legs 22 and extend into the base surface, thereby fixing the entire sand mixer 1. After the coated sand is mixed inside the sand mixer 1, it is discharged through the discharge pipe.

[0046] In this invention, the screw conveyor 5 is rotatably connected to the inside of the connecting frame 3 via the rotating shaft 4.
