[0050] The working principle and use method of a suction and unloading integrated grain conveying device of this embodiment:

[0051] The present embodiment provides an integrated suction and unloading grain conveying equipment, which establishes electrical connections with the fan, the rotating device 6, the adjusting device 7, the dust removal device 9, and the conveying equipment through the PLC controller in the control room 8, so as to realize automatic control of the whole set of equipment, such as the wind strength of the fan, the rotation angle of the rotating platform 5, the pitch and horizontal movement of the suction pipeline 3, etc., so as to realize precise control of the grain conveying process; the driving motor 62 of the rotating device 6 is connected to the rotating bearing 63 through the reducer, and drives the rotating cylinder 61 to rotate, thereby driving the rotating platform 5 to rotate freely, so that the suction pipeline 3 and the discharge pipeline 4 can be adjusted to the appropriate position according to the operation requirements; the adjusting device 7 accurately controls the horizontal rotation and pitch movement of the suction pipeline 3 through the coordinated operation of the rotating turntable 71, the pitch driving assembly 72 (including the driving cylinder 721 and the telescopic beam arm 722) and the universal pipe hinge 73, so that it can adapt to grain piles of different heights and angles, enhance the suction efficiency, and the fan is started Afterwards, negative pressure is formed in the suction pipeline 3, which attracts the grain to enter the pipeline system through the suction nozzle 36 of the vertical material pipe 35. The suction pipeline 3 includes horizontal and curved pipes 32, ball joints 33 and other components. The horizontal rotation and precise adjustment of the pitch angle of the suction pipeline 3 are achieved through the adjustment device 7 (including a rotating turntable 71, a pitch drive component 72, a universal pipe hinge 73, etc.) to adapt to materials of different heights and angles. The design of the ball joint 33 and the vertical material pipe 35 ensures the flexibility of the suction process and the stable transmission of the material. The material passes through the dust removal device 9 to remove dust and impurities in the air, and then enters the discharge pipeline 4 (conveyor 41 and discharge chute 42), and is transported to the discharge chute 42 through the conveyor 41 on the plank road 10, so that the grain is transported to the designated position. During the transportation process, the dust suppression air duct 91 is used to extract and filter out the tiny dust generated during the transportation process, so as to keep the working environment clean and reduce the loss and pollution of grain during transportation.

[0052] Before use, the operator needs to confirm that all parts of the equipment are firmly installed and undamaged, especially check whether the suction pipe 3, the discharge pipe 4, the rotary platform 5 and the protective facilities are intact. Then the operator enters the control room 8 through the ladder 13, turns on the power, starts the PLC control system, and performs a self-check of the equipment to ensure that all parts such as the fan, the rotary device 6, the adjustment device 7 and the dust removal device 9 are in standby mode; then the wind strength of the fan, the desired rotation angle of the rotary platform 5, the preset pitch and horizontal movement range of the suction pipe 3 are set through the PLC control system; these parameters should be adjusted based on the height and density of the grain stacking and the specific layout of the operation area to achieve the best suction and transportation effect.

The adjusting device 7 drives the suction pipeline 3 to move precisely according to the preset or real-time adjusted angle and position requirements, so that the suction nozzle 36 is accurately inserted into the grain pile. The fan starts to run, generates negative pressure, and starts the suction operation. The sucked grain passes through the dust removal device 9 and is then sent to the discharge pipeline 4. The grain is smoothly transported along the plank road 10 to the discharge chute 42 through the conveyor 41, and finally delivered to the designated storage or processing area; when the transportation task is completed, the suction process is stopped first to ensure that there is no residual grain in the pipeline, and then the fan, conveyor 41 and other moving parts are gradually deactivated; finally, a comprehensive equipment inspection and necessary cleaning and maintenance are carried out to prepare for the next operation.
