[0002] Shot blasting machine is a casting equipment that uses high-speed projectiles ejected from the shot blasting device to clean or strengthen the surface of the casting. The shot blasting machine uses one or more sand materials to hit the surface of the metal to remove some attachments on the metal surface, such as rust, or to obtain a specific surface layer through shot blasting.

[0003] The Chinese patent publication number CN221111378U discloses a discharge mechanism for a shot blasting machine. After the workpiece is polished by the launcher, the fallen projectiles and rust are transported to the collection tube through the feed conveyor belt. The separation mechanism is activated, and the projectiles are attracted to the left side of the distribution box by the permanent magnet. The rust will not be attracted by the permanent magnet and will fall into the right side of the distribution box, achieving the purpose of automatic separation of waste materials, saving time and effort.

[0024] The present utility model provides a blanking mechanism for a shot blasting machine through improvement. The technical solution of the present utility model is:

[0025] As Figures 1-4As shown in the figure, a blanking mechanism for a shot blasting machine includes a shot blasting machine body 1. A collection box 4 is fixedly connected to the shot blasting machine body. Two collection boxes are slidably connected to the bottom of the collection box 4, respectively used for collecting rust and shot. A conveyor belt 2 is fixedly connected to the collection box 4, and a hair dryer 3 is fixedly connected to the conveyor belt 2. A blanking component 5 is provided on the collection box 4. The blanking component 5 includes a fixed column 51, a blanking hopper 52, a blanking pipe 53, an electromagnet 54, a protective shell 55, a first motor 56, a first bevel gear 57, a second bevel gear 58, a rotating column 59, a fixed disk 510, a rotating disk 511, a first chain 512, and a through hole 513. Four fixed columns 51 are fixedly connected to the collection box 4. The blanking hopper 52 is fixedly connected to the four fixed columns 51. The two ends of the blanking pipe 53 are respectively fixedly connected to the blanking hopper 52 and the collection box 4. The electromagnet 54 is rotatably connected to the collection box 4, and the diameter of the electromagnet 54 is larger than the diameter of the blanking pipe 53. The protective shell 55 is fixedly connected to the collection box 4. The first motor 56 is fixed to the protective shell 55 by bolts. The electromagnet 54 is fixed to the output shaft of the first motor 56 by bolts. The first bevel gear 57 is fixed to the output shaft of the first motor 56 by bolts. The rotating column 59 is rotatably connected to the blanking hopper 52 and the protective shell 55. The second bevel gear 58 is fixedly connected to the rotating column 59. The first bevel gear 57 meshes with the second bevel gear 58, and the diameters of the first bevel gear 57 and the second bevel gear 58 are the same. The fixed disk 510 is fixedly connected to the blanking pipe 53. The rotating disk 511 is rotatably connected to the blanking pipe 53. The diameters of the fixed disk 510, the rotating disk 511, and the inner wall of the blanking pipe 53 are the same. The first chain 512 is arranged between the rotating column 59 and the rotating disk 511. A plurality of through holes 513 are respectively opened on the fixed disk 510 and the rotating disk 511. An auxiliary component 6 is provided on the collection box 4.

[0026] Further, as Figure 4 shown, the auxiliary component 6 includes a second chain 61 and a rotating shaft 62. The rotating shaft 62 is rotatably connected to the collection box 4, and the diameter of the rotating shaft 62 is the same as the diameter of the output shaft of the first motor 56. The second chain 61 is arranged between the rotating shaft 62 and the output shaft of the first motor 56.

[0027] Further, as Figure 3 and Figure 4 shown, the auxiliary component 6 further includes a convex block 63 and a sliding groove 64. The convex block 63 is fixedly connected to the rotating shaft 62, and the length of the convex block 63 is equal to the length of the sliding groove 64. The through hole 513 is opened on the collection box 4.

[0028] Further, as Figure 3 and Figure 4 shown, the auxiliary component 6 further includes a spring 65 and a sliding block 66. The sliding block 66 is slidably connected to the sliding groove 64. The cross-section of the sliding block 66 is in the shape of an "H". The two ends of the spring 65 are respectively fixedly connected to the sliding groove 64 and the sliding block 66.

[0029] Further, as Figure 3 shown, the auxiliary component 6 further includes a knocking rod 67. Two knocking rods 67 are fixedly connected to the sliding block 66, and the two knocking rods 67 are symmetrical about the spring 65.

[0030] Further, as Figures 2-4 shown, the auxiliary component 6 further includes a second motor 68 and a rotating plate 69. The second motor 68 is fixed to the collection box 4 by bolts. The rotating plate 69 is rotatably connected inside the collection box 4. The length of the rotating plate 69 is less than the inner wall length of the collection box 4. The rotating plate 69 is fixed to the output shaft of the second motor 68 by bolts.

[0031] The specific working method is as follows: After the workpiece is processed, it is removed from the shot blasting machine body 1 and passes through the blanking hopper 52. The rust at the bottom of the workpiece will enter the blanking hopper 52. When the workpiece to be processed is moved onto the conveyor belt 2, the hair dryer 3 is started. The hair dryer 3 is used to blow the rust and shot on the surface of the workpiece into the blanking hopper 52. Subsequently, the first motor 56 is started, and its output shaft drives the first bevel gear 57 to rotate. Since the first bevel gear 57 meshes with the second bevel gear 58, the second bevel gear 58 rotates accordingly, driving the rotating column 59 to rotate. Under the action of the first chain 512, the rotating disk 511 is driven to rotate, so that the through holes 513 on the rotating disk 511 and the through holes 513 on the fixed disk 510 overlap periodically. The rust and shot fall into the collection box 4 along the through holes 513. At this time, the electromagnet 54 is energized. The electromagnet 54 has magnetism and will adsorb the shot, while the rust will not be adsorbed and falls along the rotating plate 69 to the bottom of the collection box 4. The electromagnet 54 rotates with the rotation of the first motor 56. Under the action of the second chain 61, the rotating shaft 62 starts to rotate, driving the convex block 63 to rotate. When the convex block 63 meets the sliding block 66, it will push the sliding block 66 to move towards the spring 65, squeezing the spring 65. When the convex block 63 moves away from the sliding block 66, under the action of the spring 65, the sliding block 66 resets and pushes the knocking rod 67 to move towards the electromagnet 54, knocking the electromagnet 54 to make it vibrate, separating the rust mixed in the shot from the shot. After the rust is cleaned up, the second motor 68 is started, and its output shaft drives the rotating plate 69 to rotate, making the rotating plate 69 tilt towards the other side of the collection box 4. At this time, the electromagnet 54 is powered off, and the electromagnet 54 loses magnetism. The shot falls off the electromagnet 54 and lands on the bottom of the collection box 4 along the rotating plate 69, thus completing the separation of the shot and the rust.

The matters not covered in the present utility model belong to the common general knowledge of those skilled in the art.
