[0023] Preferably: the protective mechanism includes: a placement groove 14, a blocking net 15, a bolt 16 and a fixing hole 17. A placement groove 14 is opened on the inner surface of the feed hopper 2, and the inner surface of the placement groove 14 is connected to the blocking net 15. A bolt 16 is penetrated and connected to one side surface of the blocking net 15, and one end of the bolt 16 extends into the fixing hole 17 opened inside the feed hopper 2.

[0024] When in use, the blocking net 15 is slidably placed in the placement groove 14, and then the bolt 16 is penetrated through the blocking net 15 and screwed into the fixing hole 17, so that the position of the blocking net 15 can be fixed in the placement groove 14, so that the blocking net 15 will cover and protect one end of the air inlet 3.

[0025] Preferably, the position of the inner space of the air inlet 3 is connected to the position of the inner space of the connecting pipe 4 .

[0026] During specific use, the air in the air intake port 3 can enter the connecting pipe 4 , so when suction is generated in the air intake port 3 , the flying dust in the feed hopper 2 will be transported to the connecting pipe 4 .

[0033] Working principle: when using the automatic dust removal device of the sand making machine, when the main machine 1 of the sand making machine is performing sand making operation, dust will fly outward from the feed hopper 2. At this time, the dust suction fan 6 is started, and the dust suction fan 6 will generate suction in the connecting pipe 4 through the three-way pipe 5, so that the air intake port 3 connected to the connecting pipe 4 will generate suction, so that the dust flying outward from the feed hopper 2 will be sucked into the air intake port 3, so that the dust passes through the connecting pipe 4 and the three-way pipe 5 and then through the dust suction fan 6 from the feeding pipe 7 to be input into the collecting box 8 for collection, and the automatic dust removal operation is never completed, so as to avoid the dust flying in the feed hopper 2 from polluting the working environment. The dust collection in the collecting box 8 can be observed through the transparent observation window 13. When the dust in the collecting box 8 needs to be cleaned, the butterfly bolt 12 is twisted to separate one end of the butterfly bolt 12 from the collecting box 8, so that the baffle 10 will be rotated through the hinge 9 to expose the opening at the bottom of the collecting box 8, thereby allowing the collecting box 8 to be opened. The dust in the collection box 8 can slide out, thereby completing the cleaning operation of the dust in the collection box 8. After cleaning is completed, the baffle 10 is rotated by the hinge 9 to make the top surface of the baffle 10 contact with the bottom surface of the collection box 8, and then the butterfly bolt 12 is penetrated through the baffle 10 and screwed into the collection box 8, so that the baffle 10 can cover the opening at the bottom of the collection box 8 again. At this time, the convex block on the inner side of the baffle 10 will contact the sealing ring 11, so that the gap between the collection box 8 and the baffle 10 will be filled by the sealing ring 11, thereby forming a sealing structure to prevent the dust in the collection box 8 from penetrating. Secondly, the baffle net 15 is slidably placed in the placement groove 14, and then the bolt 16 is penetrated through the baffle net 15 and screwed into the fixing hole 17, so that the position of the baffle net 15 can be fixed in the placement groove 14, so that the baffle net 15 will block and protect one end of the air intake port 3 to prevent larger particles from splashing into the air intake port 3 when the feed hopper 2 is feeding, resulting in blockage in the air intake port 3.
