[0027] Suction part, the suction part includes transition warehouse 1, suction pipe 2 and suction feeder 3, the suction pipe 2 is communicated transition warehouse 1 and suction feeder 3;

[0028] Check part 4, at least one group check part 4 is established on the pipeline of suction pipe 2;The check part 4 includes buffer pipe 41, filter 42 and collection bag 43, one end of buffer pipe 41 is communicated with suction pipe 2, buffer pipe 41 is installed vertically to suction pipe 2, and the other end of buffer pipe 41 is provided with throttle valve 44, and the outlet end of throttle valve 44 is provided with check valve 45, and the outlet end of check valve 45 is communicated with filter 42 and collection bag 43 respectively.

[0029] The material suction part is connected by the material suction pipe 2, and the material in the transition bin 1 is conveyed by the material suction machine 3. Specifically, in the material suction process, the material suction machine 3 generates negative pressure to vacuum-adsorb and carry the material mixed with air in the transition bin 1. The check part 4 is used to avoid the material in the material suction pipe 2 from spilling out of the air supplement opening after the equipment stops. Specifically, the buffer pipe 41 in the check part 4 is vertically installed on the top of the material suction pipe 2. When the equipment stops, the negative pressure brings the material from the material suction pipe 2 into the buffer pipe 41. The height of the buffer pipe 41 provides a buffer space for the rising of the material, wherein the large particles will naturally fall, and the small particles of the material pass through the throttle valve 44 on the top of the buffer pipe 41. The throttle valve 44 is used to control the opening of the whole check pipeline and the flow of the air supplement. The check valve 45 is arranged at the outlet end of the throttle valve 44. In the material suction process, the check valve 45 is opened under the action of the negative pressure. After the material suction is stopped, the check valve 45 is automatically closed, the returning air flow cannot be spilt out, and the material is cut off on the side of the check valve 45. The other end of the check valve 45 is provided with the collecting bag 43 and the filter 42. In the moment when the equipment stops, even if a little residual material spits out through the check valve 45, the residual material will fall into the collecting bag 43, which can avoid the waste and pollution of the environment caused by the discharge of the material, and can also avoid the blockage of the filter screen, thereby ensuring the ventilation of the filter screen.

[0030] The buffer pipe can make the large particles of the material naturally fall back, the check valve 45 can ensure that the material cannot spit out when the material suction fan 31 stops the material suction, the spit-out material can be collected through the collecting bag 43, the material accumulation is avoided, the blockage of the filter screen of the filter 42 is avoided, and the ventilation of the filter screen is ensured.

[0031] Further, the check part 4 further comprises a straight elbow pipe 46, which is arranged between the throttle valve 44 and the check valve 45.

[0032] Specifically, the straight elbow pipe 46 is connected between the throttle valve 44 and the check valve 45, the direction of the returning air flow can be changed, and the speed of the air flow is reduced when the air flow passes through the straight elbow pipe 46 into the check valve 45 from the buffer pipe 41, thereby reducing the amount of the spit-out material.

[0033] Further, the check part 4 further comprises a straight elbow pipe 46, which is arranged between the throttle valve 44 and the check valve 45.

[0034] Specifically, the filter 42 and the collecting bag 43 are connected by the right-angle tee pipe 47, the returned airflow can pass a small amount of material through the check valve 45, and the right-angle tee pipe 47 can make the material enter the collecting bag 43. As a preferred scheme of the utility model, the two outlet ends of the right-angle tee pipe 47 are vertically installed, and the filter 42 is arranged at the top of the collecting bag 43. The filter 42 and the collecting bag 43 are vertically installed, so that even if a little residual material is sprayed out, the material can also enter the collecting bag 43 at the bottom through the right-angle tee pipe 47, further ensuring the ventilation of the filter screen.

[0035] Further, the filter 42 and the collecting bag 43 are detachably connected with the right-angle tee pipe 47.

[0036] Specifically, the filter 42 and the collecting bag 43 are detachably connected with the right-angle tee pipe 47 through threads, so that the filter screen of the filter 42 can be regularly detached and cleaned, ensuring normal use of the filter screen. The collecting bag 43 can be detached, and the internal material can be cleaned.

[0037] Further, the check valve 45 comprises a valve body 451, a rotating seat 452 and a valve plate 453, the rotating seat 452 is arranged in the valve body 451, one side of the valve plate 453 is hinged to the rotating seat 452, and the valve plate 453 is arranged on the side of the valve body 451 close to the throttle valve 44.

[0038] Specifically, the valve plate 453 is arranged on the side of the valve body 451 close to the throttle valve 44, and the valve plate 453 is hinged to the rotating seat 452 in the valve body 451. During the material suction process, the valve plate 453 is turned over and opened under negative pressure, and the suction pipe 2 is supplemented with air; after the material suction machine 3 stops working, the valve plate 453 is automatically closed, so that the material cannot pass through the check valve 45.

[0039] Further, a sealing gasket 454 is arranged between the valve plate 453 and the rotating seat 452, so that the sealing property of the check valve 45 can be improved, and the leakage of the material can be avoided.

[0040] Further, the material suction machine 3 is provided with a material suction fan 31, and an exhaust valve 32 is arranged between the material suction fan 31 and the material suction machine 3.

[0041] Specifically, the material suction fan 31 on the material suction machine 3 is used to generate negative pressure, and the material is transported through the negative pressure. The exhaust valve 32 is used to release the negative pressure when the machine stops, so that the negative pressure in the suction pipe 2 is not too large when the machine stops, and more material is not introduced into the air supplementing structure.

[0042] Further, the suction machine 3 is further provided with a suction pulse device 33. Embodiment two
