Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0023] Please refer to Figures 1-6 The present application provides a technical scheme: a resin sand gas collecting device, which comprises a shell 1, a gas inlet pipe 2 connected to the lower outer side of the shell 1, a gas outlet pipe 3 connected to the upper outer side of the shell 1, a gas inlet grille frame 4 fixedly connected to the lower inner side of the shell 1, a gas inlet grille main body 5 fixedly connected to the inner side of the gas inlet grille frame 4, an air suction machine 8 arranged above the gas inlet grille frame 4, a pushing mechanism 6 arranged below the gas inlet grille frame 4, and an elastic mechanism 7 arranged inside the outer side of the gas inlet grille frame 4.

[0024] The pushing mechanism 6 comprises a gas cylinder 601 fixedly connected to the other side of the lower side of the shell 1, a gas rod 602 fixedly connected to the output end of the gas cylinder 601, a first elastic telescopic rod 603 fixedly connected to one end of the gas rod 602, a scraper 604 fixedly connected to one end of the first elastic telescopic rod 603, a first guide groove 605 arranged inside the side of the gas inlet grille frame 4 away from the gas inlet pipe 2, an a point arranged on the outer side of one end of the first guide groove 605 close to the gas cylinder 601, a b point arranged on the inner side of one end of the first guide groove 605 close to the gas cylinder 601, a c point arranged on the outer side of one end of the first guide groove 605 away from the gas cylinder 601, a d point arranged on the inner side of one end of the first guide groove 605 away from the gas cylinder 601, a first hole 606 arranged inside the gas rod 602, a push rod 607 arranged inside the first hole 606, the inner side surface of the first hole 606 being attached to the outer side surface of the push rod 607, the appearance structure of the push rod 607 being a cuboid, the central axis of the push rod 607 being perpendicular to the central axis of the gas rod 602, so that the push rod 607 does not rotate and shake when moving inside the first hole 606, the first guide groove 605 being provided with a first guide rod 608 fixedly connected to the push rod 607, the a point of the first guide groove 605 being farther away from the gas inlet pipe 2 than the b point of the first guide groove 605, and the c point of the first guide groove 605 being closer to the gas inlet pipe 2 than the d point of the first guide groove 605, so that the first guide rod 608 moves to the a point and moves back to the side of the first guide groove 605 farther away from the gas inlet pipe 2.

[0025] The elastic mechanism 7 comprises a bearing plate 701 fixedly connected to the side of the scraper 604 away from the air cylinder 602, a second hole 703 is arranged in the inner side of the air inlet grille frame 4 away from the air cylinder 601, a first baffle 704 is arranged in the inner side of the second hole 703, a third hole 705 is arranged on the side of the first guide groove 605 close to the shell 1, a sliding plate 706 is slidably connected to the inner side of the third hole 705, a second baffle 707 is arranged on the outer side of the sliding plate 706, a second guide groove 708 is arranged on the inner side of the sliding plate 706, a second guide rod 709 is arranged in the second guide groove 708, the connection between the second guide rod 709 and the first baffle 704 is fixed connection, the second elastic telescopic rod 710 is fixedly connected between the second baffle 707 and the air inlet grille frame 4, the collecting box 711 is communicated to the side of the shell 1 away from the air cylinder 601, the outer appearance structure of the second guide groove 708 is inclined straight line, and the cooperation between the second guide groove 708 and the second guide rod 709 is gap cooperation, so that the second guide groove 708 can drive the second guide rod 709 to move up and down when the second guide groove 708 moves horizontally, the outer side of the upper end of the first baffle 704 is attached to the inner side of the second hole 703, the width of the lower end of the first baffle 704 is less than the width of the upper end of the first baffle 704, and the central axis of the first baffle 704 is perpendicular to the upper plane of the air inlet grille frame 4, so that the first baffle 704 will not shake when moving in the inner side of the second hole 703.

[0026] When it is necessary to clean large particles, the air cylinder 601 drives the air rod 602, the first elastic telescopic rod 603, the scraper 604 and the bearing plate 701 to move horizontally. Because the air suction machine 8 is working, the large particles are always moving on the lower surface of the air inlet grid main body 5, so that the bearing plate 701 is in contact with the inner side of the first baffle 704. At this time, the upper part of the bearing plate 701 is blocked by the lower surface of the air inlet grid frame 4, and the other side is blocked by the first baffle 704. The air pressure does not affect the large particles above the bearing plate 701. At this time, the air cylinder 601 is continuously started to drive the air rod 602 to move, so that the push rod 607 and the first guide rod 608 move. At this time, the first guide rod 608 is on the side of the first guide groove 605 away from the air inlet pipe 2. The push rod 607 pushes the sliding plate 706 to move horizontally, driving the second guide groove 708 to move horizontally. Because the outer appearance structure of the second guide groove 708 is an inclined straight line, and the cooperation mode of the second guide groove 708 and the second guide rod 709 is gap cooperation, the second guide rod 709 and the first baffle 704 move upward. At this time, the first elastic telescopic rod 603 has stored energy. Because the upper end of the first baffle 704 is in contact with the inner side of the second hole 703, and the lower end of the first baffle 704 is smaller than the upper end of the first baffle 704, when the bearing plate 701 is aligned with the lower end of the first baffle 704, the bearing plate 701 and the scraper 604 will collide with the first baffle 704, so that the large particles inside are extruded, facilitating collection. When the first baffle 704 moves out of the range of the bearing plate 701, the first elastic telescopic rod 603 still has a certain amount of stored energy, which drives the bearing plate 701 and the scraper 604 to move to the inner side of the collection box 711, so that the large particles move to the collection box 711 under the action of inertia. When the air rod 602 moves back, because point a of the first guide groove 605 is farther away from the air inlet pipe 2 than point b of the first guide groove 605, and point c of the first guide groove 605 is closer to the air inlet pipe 2 than point d of the first guide groove 605, the first guide rod 608 can move to the side of the first guide groove 605 close to the air inlet pipe 2 when it moves back to point c, so that the push rod 607 loses control of the first baffle 704 and moves horizontally. The second elastic telescopic rod 710 immediately resets, and the first baffle 704 moves downward to the inner side of the bearing plate 701. When the bearing plate 701 moves back, the large particles on its surface are scraped off. As described above, the large particles can be scraped off while the air suction work continues uninterrupted, reducing damage to the air inlet grid.
