[0034] Please see the attached Figure 1 To the attached Figure 5 As shown, the present invention provides a device for preventing a blowing nozzle from connecting to an air pipe and piling up materials for a color sorter, comprising:

[0035] Protective mechanism 1, protective mechanism 1 includes a seat plate 11 and a shield 12, the interior of the shield 12 is provided with an injection mechanism 5 for blowing out heterochromatic particulate materials, the injection mechanism 5 includes a nozzle 51 and a nozzle connecting air pipe 52, the seat plate 11 and the shield 12 are fixedly connected, the interior of the shield 12 is fixedly installed with a nozzle mounting seat 53, the nozzle 51 is installed inside the shield 12 through the nozzle mounting seat 53, the rear end of the nozzle 51 is connected to the nozzle connecting air pipe 52, the nozzle connecting air pipe 52 passes through the base 21 and is connected to the nozzle air valve, the inner wall of the shield 12 is fixedly provided with a guide column 14, the inner wall of the shield 12 is provided with a rotation groove 13, the bottom of the protective mechanism 1 is provided with a guide seat mechanism 2, the guide seat mechanism 2 includes a bottom fixedly connected to the seat plate 11 The seat 21 has a discharge port 22 formed on the side of the base 21, a sliding roller 23 is installed at the bottom of the discharge port 22, and the outer surface of the sliding roller 23 is located inside the discharge port 22, the sliding roller 23 is in rolling contact with the guide plate 35, a lifting airbag 25 is provided inside the base 21, and lifting plate guide grooves 27 are formed at both ends of the base 21, and a lifting plate guide column 28 is fixedly installed inside the lifting plate guide groove 27, a lifting base 24 is fixedly installed on the inner wall of the base 21, and the lifting airbag 25 is fixedly installed inside the base 21 through the lifting base 24, and an airbag connecting nozzle 26 is fixedly installed at the bottom of the lifting base 24, and the airbag connecting nozzle 26 is connected to the lifting airbag 25, and the lifting airbag 25 is connected to the lifting air valve through the airbag connecting nozzle 26;

[0036] The installation of the injection mechanism 5 is achieved through the protection mechanism 1 and the guide seat mechanism 2, and the nozzle connecting air pipe 52 is protected by the seat plate 11, which prevents the nozzle connecting air pipe 52 from being damaged by the outside world and avoids the problem of material flying out when material jumping occurs.

[0037] The material guiding mechanism 3 is arranged inside the guide seat mechanism 2, and is used for guiding the material which falls into the interior of the base 21 to the outside of the guide base 21. The material guiding mechanism 3 includes a lifting plate 31 and a material guiding plate 35. The lifting plate 31 is connected with the lifting air bag 25, and the lifting air bag 25 can control the lifting plate 31 to rise or fall. The surface of the lifting plate 31 is provided with a plug hole 32, and the lifting plate 31 is sleeved on the surface of the nozzle connecting air pipe 52 through the plug hole 32. Lifting blocks 33 are fixedly installed at both ends of the lifting plate 31. The lifting block 33 is slidably arranged inside the lifting plate guide groove 27. The surface of the lifting block 33 is provided with a lifting guide hole 34. The lifting block 33 is slidably sleeved on the surface of the lifting plate guide column 28 through the lifting guide hole 34. The material guiding plate 35 is hinged to the lifting plate 31, and the material guiding plate 35 is slidably inserted into the inside of the discharge port 22;

[0038] When the nozzle air valve is opened and the nozzle 51 is controlled to spray air through the nozzle-connected air pipe 52, the lifting air valve is opened at the same time, and air pressure is injected into the interior of the lifting airbag 25, causing the lifting airbag 25 to expand and stretch, and lift the lifting plate 31 upward. During the rising process, the lifting plate 31 will drive the side of the guide plate 35 away from the discharge port 22 to rise, so that the surface of the guide plate 35 is tilted, so that the material falling onto the surface of the guide plate 35 is discharged through the discharge port 22, and when the lifting plate 31 drives the guide plate 35 to tilt, one side of the guide plate 35 is pulled by the lifting plate 31, so that the surface of the guide plate 35 forms a thrust toward the discharge port 22, thereby causing the material on the surface of the guide plate 35 to be discharged through the discharge port 22 more quickly.

[0039] The material shaking mechanism 4 is arranged inside the protective cover 12, and the material shaking mechanism 4 is used to shake off the material that falls on the nozzle connecting air pipe 52, and the material shaking mechanism 4 includes a material shaking lifting plate 41 and a material shaking rod 48, and the material shaking lifting plate 41 is fixedly connected to the lifting plate 31, and the surface of the material shaking lifting plate 41 is provided with a material shaking rod accommodating groove 42 and a material shaking rod giving way groove 43, and the material shaking lifting plate 41 is provided with two groups, and the two groups of material shaking lifting plates 41 are respectively arranged at the two ends of the lifting plate 31, and the surface of the material shaking lifting plate 41 is provided with a guide groove 46, and the material shaking lifting plate 41 is slidably sleeved on the surface of the guide column 14 through the guide groove 46, and the surface of the material shaking lifting plate 41 is fixedly installed with a return guide plate positioning column 44 and a return guide plate rotating shaft 45, and the surface of the return guide plate rotating shaft 45 is rotatably provided with a return guide plate 47, and the surface of the return guide plate 47 is provided with a return guide plate rotating shaft hole 471. The return guide plate 47 is provided with an arc guide groove 472 on the surface of the return guide plate 47, and the return guide plate 47 is slidably sleeved on the surface of the return guide plate positioning column 44 through the arc guide groove 472. The two ends of the shaking rod 48 are fixedly mounted with cranks 481, and the surface of the crank 481 is fixedly mounted with a shaking rod rotating shaft 482. The shaking rod rotating shaft 482 is rotatably inserted into the interior of the rotating groove 13, and a second torsion spring is provided between the shaking rod rotating shaft 482 and the inner wall of the rotating groove 13.

[0040] When the lifting airbag 25 lifts the lifting plate 31 upward, the lifting plate 31 drives the shaking lifting plates 41 at both ends to rise synchronously. During the rising process of the shaking lifting plates 41, the side walls of the shaking rod accommodating groove 42 squeeze the shaking rod 48, causing the shaking rod 48 to detach from the inside of the shaking rod accommodating groove 42 and move away from the shaking lifting plate 41. Then, after passing the side of the return guide plate 47, the shaking rod 48 quickly falls into the inside of the shaking rod yielding groove 43 under the action of the torsion spring. At the same time, the shaking rod 48 hits the surface of the nozzle connecting air pipe 52, causing the nozzle connecting air pipe 52 to shake, thereby shaking the material falling on the surface of the nozzle connecting air pipe 52 to the surface of the guide plate 35, avoiding the accumulation of material between the nozzle connecting air pipe 52.

[0041] After the shaking of the material is completed, the air pressure inside the jacking airbag 25 is extracted, driving the lifting plate 31 to descend, and at the same time the lifting plate 31 drives the shaking material lifting plate 41 to descend synchronously. At this time, the shaking material rod 48 and the return guide plate 47 squeeze each other, causing the return guide plate 47 to rotate. When the other end of the arc guide groove 472 is in contact with the return guide plate positioning column 44, the return guide plate 47 is tilted. At this time, the end of one side surface of the return guide plate 47 is docked with the side of the shaking material rod giving way groove 43 opening close to the shaking material rod accommodating groove 42, so that the shaking material rod 48 can slide out of the shaking material rod giving way groove 43 through the side of the return guide plate 47 and return to the inside of the shaking material rod accommodating groove 42.

[0042] In summary, in this case, by setting the material guiding mechanism 3 and the material shaking mechanism 4, the material falling on the nozzle connecting air pipe 52 is shaken off, and the shaken-off material is discharged and collected at the same time.

[0043] Working principle: During the use of the color sorter, when the photoelectric detection mechanism detects heterochromatic granular materials, the nozzle air valve opens, and the nozzle 51 is controlled to eject air through the nozzle-connected air pipe 52. The lifting air valve opens at the same time, and the air pressure is injected into the interior of the lifting airbag 25, causing the lifting airbag 25 to expand and stretch, and push the lifting plate 31 upward. During the rising process, the lifting plate 31 will drive the side of the guide plate 35 away from the discharge port 22 to rise, so that the surface of the guide plate 35 is tilted, so that the material falling onto the surface of the guide plate 35 is discharged through the discharge port 22, and when the lifting plate 31 drives the guide plate 35 to tilt, one side of the guide plate 35 is pulled by the lifting plate 31, so that the surface of the guide plate 35 forms a thrust toward the discharge port 22, thereby causing the material on the surface of the guide plate 35 to pass through the discharge port more quickly. The material is discharged from the outlet 22, and while the lifting airbag 25 lifts the lifting plate 31 upward, the lifting plate 31 drives the shaking material lifting plates 41 at both ends to rise synchronously. During the rising process of the shaking material lifting plates 41, the side walls of the shaking material rod accommodating groove 42 squeeze the shaking material rod 48, causing the shaking material rod 48 to detach from the inside of the shaking material rod accommodating groove 42 and move away from the shaking material lifting plate 41. Then, after passing the side of the return guide plate 47, the shaking material rod 48 quickly falls into the inside of the shaking material rod yielding groove 43 under the action of the torsion spring. At the same time, the shaking material rod 48 slaps the surface of the nozzle connecting air pipe 52, causing the nozzle connecting air pipe 52 to shake, thereby shaking the material falling on the surface of the nozzle connecting air pipe 52 to the surface of the guide plate 35, avoiding the accumulation of material between the nozzle connecting air pipe 52.
