After the agricultural products are placed on the surface of the conveying device, a certain intensity of gas can be automatically delivered to the corresponding airbag 111, so that the airbag 111 has a certain shock-absorbing ability. After the agricultural products are transported to the designated position, the dust on the surface of the airbag 111 can be cleaned and the gas inside the airbag 111 can be automatically discharged. While avoiding the long-term inflation of the airbag 111, which will accelerate material fatigue and affect the service life of the airbag 111, it is also convenient for the subsequent placement of other agricultural products.

[0041] The dust cleaning component 33 includes a dust suction pipe 331 and a dust suction ring 332. The lower end of the dust suction pipe 331 is connected to the upper side wall of the collecting box 9. The dust suction ring 332 is a hollow structure.

[0042] The upper side wall of the horizontal plate 8 is fixedly connected with a cleaning motor 36 , and the output end of the cleaning motor 36 is fixedly connected with a cleaning brush 37 , which can clean the dust attached to the surface of the cleaning brush 35 .

[0043] The side walls on the opposite sides of the two support plates 6 are fixedly connected to a support seat 38, the lower side wall of the support seat 38 is fixedly connected to a hydraulic push rod 39, the movable end of the hydraulic push rod 39 is fixedly connected to a lifting seat 40, and the lower side wall of the lifting seat 40 is fixedly connected to a plurality of support wheels 41, which improves the convenience of movement of the conveying device.

[0044] A third control valve 42 is provided inside the air outlet end of the air pump 10, and a short tube 43 is connected to the air outlet end of the air pump 10. A fourth control valve 44 is provided inside the short tube 43. A second air pressure sensor 45 is connected to the side wall of the air supply box 191. The second air pressure sensor 45 is electrically connected to the third control valve 42 and the fourth control valve 44 through the PLC controller 7, so that a certain air pressure can be maintained in the air supply box 191 at all times.

[0045] The operating principle of the present invention is described as follows: the agricultural products are placed on the surface of the airbag 111 in sequence through an external device (the external device is a mechanical arm or other device). After the agricultural products are placed on the surface of the airbag 111, the pressure sensor 13 on the surface of the placement seat 12 is squeezed under the action of gravity. After the pressure sensor 13 detects pressure from above, the pressure sensor 13 controls the corresponding micro-electric push rod 16 to work through the PLC controller 7, and the micro-electric push rod 16 drives the limit pin 17 to be inserted into the limit groove 18. When the rotating tube When the conveyor belt 4 is driven to move, the conveyor belt 4 will drive the multiple baffles 5 and the multiple air bags 111 on the surface to move from right to left. During the movement, the baffles 5 will drive the air inlet hood 22 to move together through the bent pipe 21. During the movement, the air inlet hood 22 will contact the rear side wall of the air delivery box 191, and the extrusion plate 26 on the upper side of the air inlet hood 22 will squeeze the multiple trigger buttons 24 above during the movement. The trigger button 24 will control the corresponding first control valve 20 below to open through the PLC controller 7. At this time, the air pressure in the air delivery box 191 is relatively high, and the air Under the action of pressure, the product will be transported to the air intake hood 22 through the air supply pipe 192 (when the extrusion plate 26 squeezes a trigger button 24, the air supply pipe 192 aligned with the trigger button 24 is in the air intake hood 22. After multiple trigger buttons 24 are squeezed, multiple air supply pipes 192 will open to ensure the air supply amount). After entering the air intake hood 22, the air supply pipe 192 will be transported to the air bag 111 through the bent pipe 21, so that the air bag 111 swells up. At this time, the placement seat 12 under the agricultural product is limited by the limit pin 17 and the limit groove 18. The airbag 111 below the agricultural product does not swell because the airbag 111 is locked with the limiting cylinder 112. Therefore, a placement groove is formed directly below the agricultural product, thereby preventing the agricultural product from rolling during the movement, and preventing the agricultural product from rolling and colliding with mechanical parts during the transportation of the agricultural product, so that the juice of the agricultural product penetrates into the mechanical parts and affects the normal operation of the mechanical parts. In addition, a rubber seat is provided on the surface of the placement seat 12, which can reduce the vibration caused by the conveying device to a certain extent, thereby reducing the damage to the agricultural product caused by the vibration.

[0046] When the first air pressure sensor 29 detects that the air pressure inside the airbag 111 reaches the set threshold, the first air pressure sensor 29 will control the electromagnetic one-way valve 30 to cut off the power and close through the PLC controller 7 (the electromagnetic one-way valve 30 is mainly composed of a valve body, a valve core, a spring, an electromagnet and other components. The valve body is the main part of the valve and provides a fluid channel. Under the action of the spring, the valve core is usually in a closed position to prevent the gas from flowing in the opposite direction. When the electromagnet is energized, an electromagnetic force is generated to attract the valve core, so that the valve opens and allows the fluid to flow in the forward direction) to prevent the gas from continuing to enter the airbag 111. When the second air pressure sensor 45 detects that the air pressure inside the air delivery box 191 decreases, the second air pressure sensor 45 will control the fourth control valve 44 to close, and control the third control valve 42 to open, and the air pump 10 is always in a working state, and the air pump 10 can deliver external gas to the air delivery box 191. When the air pressure inside the air delivery box 191 reaches the set threshold, the second air pressure sensor 45 will control the third control valve 42 to close, and control the fourth control valve 44 to open through the PLC controller 7, so as to prevent the external gas from being continuously delivered to the air delivery box 191;

[0047] When the conveying device completes the conveying task, the agricultural products on the surface of the conveying device will be removed, and when the conveyor belt 4 drives the airbag 111 and the baffle 5 to rotate to the bottom of the roller 2, the laser signal emitted by the laser generator 31 on the left side will be received by the laser receiver 32 on the surface of the baffle 5. When the laser receiver 32 receives the laser signal for the first time, the laser receiver 32 will control all the corresponding micro-electric push rods 16 to work through the PLC controller 7, so that the micro-electric push rods 16 drive the limit pin 17 to retract (the micro-electric push rods 16 originally in the retracted state will not move, and only the micro-electric push rods 16 originally in the extended state will work), thereby releasing the limit between all the placement seats 12 and the limit cylinders 112, and the airbags 111 will all swell up. When the swollen airbags 111 pass over the cleaning brush 35, the dust on the surface of the airbags 111 will be cleaned off by the cleaning brush 35. At this time, the air pump 10 is in working condition, and the air pump 10 will The gas inside the collecting box 9 is discharged, and the external gas will carry dust through the dust suction hole 34 into the dust suction ring 332 under the action of negative pressure, and be transported to the collecting box 9 for storage through the dust suction pipe 331. When the air bag 111 after dust removal is continued to be transported to the right by the conveyor belt 4, it will pass through the front laser generator 31, and the laser signal emitted by the front laser generator 31 will be received again by the laser receiver 32 there and transmitted to the PLC controller 7. After receiving the laser signal again, the PLC controller 7 will control the corresponding second control valve 28 to open, so that the gas inside the air bag 111 is discharged from the air bag 111 through the bend pipe 21 and the exhaust pipe 27, so that the air pressure inside the air bag 111 and the bend pipe 21 drops synchronously. When the first air pressure sensor 29 detects that the air pressure inside the bend pipe 21 drops to the set threshold, the first air pressure sensor 29 will control the electromagnetic one-way valve 30 to be energized and opened through the PLC controller 7, so as to facilitate the subsequent placement of agricultural products.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
