The invention has the following beneficial effects:

1. the bell mouth guides the sand outlet of the sand bag to accurately fall on the cutter point, so that only the sand outlet of the sand bag is broken when the sand is broken, and the sand bag is not damaged;

2. when the sand is broken, a sand outlet channel is automatically established to assist in forming cylindrical sand flow, and the shakeout is stable and rapid;

3. the auxiliary blade can cut the inner bag, meanwhile, the stress of the connecting rod is enhanced, and the inner bag is guided to slide outwards;

4. the inner bag of the sand bag is prevented from falling, stacking and winding, so that the sand outlet of the sand tank is prevented from being blocked;

5. the hollow tool rest is convenient for sand flow to pass through, and can prevent foreign matters from forming blockage at the sand breaking opening;

6. the rhombus filter screen can bear sand bags or inner bags which accidentally slide off, and does not need to be cleaned immediately.
