[0027] Reference Figure 1-5 The utility model provides an anti-clogging sand falling machine, including a supporting leg 1, a spring 2 is fixedly connected to the upper end of the supporting leg 1, a connecting frame 3 is fixedly connected to the upper end of the spring 2, a box 4 is fixedly connected to the side end of the connecting frame 3, a vibration motor 5 is fixedly connected to the front and rear ends of the box 4, a supporting rod 12 is fixedly connected to the inside of the box 4, a plurality of supporting rods 12 are arranged, and are evenly distributed inside the box 4, a dredging mechanism 8 is arranged inside the box 4, and the dredging mechanism 8 is used to dredge the molding sand between the two supporting rods 12, and a discharge port 6 is fixedly connected to the lower end of the box 4.

[0028] Specifically, first turn on the vibration motor 5, then the box body 4 can be vibrated under the action of the vibration motor 5, and then the molding sand and the casting can be placed on the support rod 12. At this time, the molding sand and the casting can be separated as the vibration motor 5 works, and the separated molding sand falls from the gaps between the support rods 12, and finally discharged from the discharge port 6 to facilitate secondary utilization later. When the gaps between the support rods 12 need to be dredged, the dredging mechanism 8 can dredge the gaps between the support rods 12, thereby avoiding the molding sand from being blocked between the support rods 12, which is conducive to the falling of the molding sand and improves the falling efficiency of the molding sand.

[0029] The dredging mechanism 8 includes a second motor 801, a crankshaft 802, a mobile frame 803, a dredging rod 804 and a linkage rod 805. The crankshaft 802 is rotatably connected inside the box body 4. The circumferential surface of the crankshaft 802 is rotatably connected to the linkage rod 805. The end of the linkage rod 805 away from the crankshaft 802 is rotatably connected to the mobile frame 803. The upper end of the mobile frame 803 is fixedly connected to the dredging rod 804.
