[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0020] See also Figure 1-4A dust hood for casting processing with a dust-proof effect includes a dust hood body 1, a dust suction groove 2 is opened inside the dust hood body 1, a dust inlet hole 3 is opened on the inner wall of the dust hood body 1, the dust suction groove 2 is connected to the suction port of the suction pump 4, a cleaning mechanism 5 is provided inside the dust hood body 1, and an anti-blocking component 6 is provided in the inner wall of the dust hood body 1. The cleaning mechanism 5 includes a motor 51, the motor 51 is fixedly connected to the outer wall of the dust hood body 1, and the output shaft of the motor 51 is fixedly connected to a reciprocating screw rod 52. The reciprocating screw rod The rod 52 is slidably connected to the slider 53 through the reciprocating groove opened on the surface. The slider 53 is fixedly connected to the control block 54. The control block 54 is in the shape of a hollow rectangular parallelepiped, and the control block 54 does not contact the inner wall of the dust collector body 1. By setting the shape of the control block 54, it is ensured that the device can achieve the effect of unidirectional and multi-faceted cleaning at the same time. The control block 54 is slidably connected to the moving block 55. The moving block 55 passes through the inner wall of the control block 54. The friction between the moving block 55 and the control block 54 is large, and when there is no external force The moving block 55 cannot move. The control block 54 is slidably connected to a scraper 56. The surface material of the scraper 56 is soft rubber, and a metal core is provided inside the scraper 56. By setting the material of the scraper 56, the scraper 56 can ensure the cleaning effect of the inner wall of the dust collector body 1 without being easily deformed. The scraper 56 is fixedly connected to a driving block 57. The driving block 57 is hinged with a connecting rod 58. The connecting rod 58 is hinged on the moving block 55. The reciprocating screw rod 52 is driven by the motor 51 to rotate, thereby making the slider 53 The control block 54 is driven to move back and forth, and contacts the moving block 55 through the upper and lower inner walls of the dust hood body 1, so that when the moving block 55 hits the upper inner wall of the dust hood body 1 and moves downward, the moving block 55 drives the connecting rod 58 to make the scraper 56 in an extended state. When the moving block 55 hits the lower inner wall of the dust hood body 1 and moves upward, the moving block 55 drives the connecting rod 58 to make the scraper 56 in a retracted state, thereby achieving the effect of driving the waste residue on the inner wall of the dust hood body 1 downward and cleaning it.

[0021] During use, when the staff needs to vacuum, the staff first starts the power supply of the equipment to start the motor 51, so that the output shaft of the motor 51 drives the reciprocating screw 52 to rotate, so that the slider 53 is driven by the reciprocating screw 52 to move back and forth, and the control block 54 is driven by the slider 53 to move back and forth up and down. When the control block 54 moves upward so that the moving block 55 contacts the top inner wall of the dust hood body 1, the moving block 55 is squeezed and moves downward, and drives the end of the connecting rod 58 connected to the moving block 55 to move downward. At this time, the connecting rod 58 moves toward both sides away from the end of the moving block 55, so that the driving block 57 moves outward, and drives the scraper 56 to move outward through the driving block 57, so that the scraper 56 is in the outer area of ​​the control block 54. At this time, the control block 54 is on the reciprocating screw 52 When the slider 53 moves downward, the scraper 56 can scrape off the waste residue on the inner wall of the dust hood body 1. When the control block 54 moves to make the moving block 55 contact the lower inner wall of the dust hood body 1, the moving block 55 is squeezed by the lower inner wall of the dust hood body 1, so that the moving block 55 moves upward, so that the moving block 55 drives the side of the connecting rod 58 close to the moving block 55 to move upward, so that the connecting rod 58 moves inward away from the end of the moving block 55, and drives the block 57 to move inward, thereby driving the scraper 56 to move inward. At this time, when the control block 54 moves upward, the scraper 56 is inside the control block 54, thereby ensuring that the scraper 56 does not contact the inner wall of the dust hood body 1 when it moves upward, thereby ensuring that the waste residue is in the area below the dust hood body 1 after being cleaned, making it convenient for the staff to clean. Example

[0022] See also Figure 1-5The air bag 62 is fixedly connected to the inner wall of the dust collection hood body 1, and a sliding block 63 is slidably connected to the inner wall of the air pressure tube 61. The sliding block 63 is slidably connected to the baffle 64, and the baffle 64 is slidably connected to the pushing block 65. The shape of the pushing block 65 is a cylinder with an inclined cut on the top, and the size of the pushing block 65 matches the dust inlet hole 3. By setting the shape of the pushing block 65, it is ensured that the pushing block 65 can push the waste residue inside the dust inlet hole 3, and at the same time, it is ensured that the pushing block 65 will not have an obstruction effect after the baffle 64 moves upward. The end of the sliding block 63 close to the baffle 64 is fixedly connected to the spring 66, and the end of the spring 66 away from the pushing block 65 is fixedly connected to the baffle The spring 66 is arranged in a groove on the outer wall of the baffle 64. By setting the tension of the spring 67 and the elastic force of the spring 66, it is ensured that when the airbag 62 is not subjected to external force, the baffle 64 can automatically reset under the drive of the spring 67 without being interfered with by the spring 66 and the pushing block 65. When the scraper 56 moves downward, the airbag 62 is squeezed, so that the gas inside the airbag 62 enters the airbag 61, thereby causing the sliding block 63 to move outward and drive the baffle 64 to move downward, thereby causing the pushing block 65 to enter the same horizontal area as the dust inlet hole 3, and causing the pushing block 65 to move outward under the drive of the spring 66, pushing the waste residue inside the dust inlet hole 3, thereby preventing the waste residue from clogging the dust inlet hole 3.

[0023] During use, based on Example 1, the airbag 62 is squeezed during the downward movement of the scraper 56, so that the gas inside the airbag 62 enters the air pressure tube 61, thereby increasing the pressure inside the air pressure tube 61, so that the sliding block 63 moves outward under the action of the air pressure, so that the sliding block 63 pushes the baffle 64 downward, so that the pushing block 65 moves to a position in the same horizontal area as the dust inlet hole 3. At this time, the pushing block 65 moves toward the center area of ​​the dust hood body 1 under the drive of the spring 66, thereby achieving the effect of pushing the waste residue inside the dust inlet hole 3 into the interior of the dust hood body 1, and at the same time ensuring that the waste residue will not enter the external area of ​​the dust hood body 1 through the dust inlet hole 3 during the downward movement of the scraper 56, thereby ensuring the use effect.
