[0038] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] refer to Figures 1 to 5 The utility model protects a raw material conveying device, which includes a conveying component 1 and a vacuum component 3 capable of conveying raw materials. The conveying component 1 includes a pipeline 11, and at least two dehumidification components 2 are fixedly arranged on the pipeline 11 along the axial direction. The dehumidification component 2 can discharge the water vapor in the conveying component 1.

[0040] The dehumidification component 2 includes a heating element and a drying element.

[0041] The heating element is fixedly arranged at the top of the pipe 11, and an exhaust port is provided at the top of the heating element. The heating element absorbs sunlight to generate heat, heating the air at the top of the pipe 11. After the air is heated, it rises and is discharged from the exhaust port.

[0042] The drying element connects the interior of the pipe 11 with the outside air, so that the outside air enters the interior of the pipe 11 after being dried by the drying element.

[0043] When the heating element is not working, the vacuum assembly 3 can provide suction to discharge the air at the top of the pipe 11.

[0044] The present invention is provided with a plurality of dehumidification components 2, and for a long pipe 11, water vapor can be dispersedly discharged at multiple positions to prevent a large amount of water vapor from accumulating in the pipe 11. By providing a heating element at the top of the pipe 11, the air at the top of the pipe 11 can be heated by absorbing sunlight, and the hot air will automatically rise and be discharged from the exhaust port, which is conducive to the discharge of water vapor. By providing a drying element, external air can pass through the drying element into the pipe 11, and dry air is replenished into the pipe. The heating element discharges water vapor, and the drying element replenishes dry air. The combination of the two can effectively reduce the humid air in the pipe 11 and prevent soybeans from deteriorating. When working at night, the heating element cannot generate heat. By providing a vacuum component 3, the air at the top of the pipe 11 is discharged using the vacuum component 3 to ensure that the external air passes through the drying element and replenishes the pipe 11, thereby reducing the humid air in the pipe 11.

[0045] In a specific embodiment, a top opening is provided on the top surface of the pipe 11 .

[0046] The heating element includes a first top plate 23 and a second top plate 25 . The first top plate 23 is a transparent plate, and the second top plate 25 is a black metal plate.

[0047] The first top plate 23 has multiple pieces, which are fixedly arranged above the top opening. The multiple first top plates 23 are connected to form a closed A-shaped top, which completely blocks the top opening. An exhaust port is provided at the top of the A-shaped top.

[0048] The second top plate 25 is parallel to the first top plate 23 . There is a gap between the second top plate 25 and the side wall of the pipe 11 . Water vapor in the pipe 11 can be discharged from the exhaust port through the gap.

[0049] In this embodiment, by providing a transparent first top plate 23 and a transparent second top plate 25, sunlight can pass through the first top plate 23 and illuminate the second top plate 25. The second top plate 25 is made of ferrous metal, which absorbs heat effectively. After absorbing heat, it heats the air between the first and second top plates 23 and 25. The hot air automatically rises and is discharged through the exhaust port. Due to the chimney effect, external air automatically passes through the drying element and enters the duct 11. This allows the air inside the duct 11 to be exhausted and dry air to enter, effectively reducing the accumulation of moisture inside the duct 11.

[0050] In one embodiment, the drying element comprises an outer panel 21 that is black.

[0051] The outer plate 21 is fixedly arranged on the outer side of the side wall of the pipeline 11, and a closed interlayer is formed between the outer plate 21 and the side wall of the pipeline 11. A desiccant 27 is detachably arranged in the closed interlayer, and the desiccant 27 can absorb water vapor.

[0052] The outer plate 21 is provided with an air inlet 211 .

[0053] An opening is provided on the side wall of the pipe 11 , and an air intake membrane 26 is fixedly provided in the opening. The air intake membrane 26 is a waterproof and breathable membrane.

[0054] This embodiment utilizes a closed interlayer, providing a large storage space. This allows for a large amount of desiccant 27 to be added, reducing the time required to replace desiccant 27. Air inlet holes 211 and openings are located on both sides of the closed interlayer, allowing sufficient contact between outside air and desiccant 27 for air drying. The waterproof, breathable membrane is provided to prevent potential damage, such as the outer layer of the closed interlayer breaking, allowing rainwater to enter the interlayer. This prevents rainwater from directly entering pipe 11, thus blocking the rainwater.

[0055] In a specific embodiment, the air inlet 211 is close to the top of the pipe 11 , and a bent plate 212 is fixed above the air inlet 211 . The bent plate 212 can block rainwater and prevent rainwater from entering directly from the air inlet 211 .

[0056] The air inlet membrane 26 is close to the bottom end of the pipe 11.

[0057] In this embodiment, the air inlet 211 is located at the top, and the air inlet membrane 26 is located at the bottom. External air enters the enclosed interlayer from the top and exits at the bottom. This air travels a long path, allowing it to fully contact the desiccant 27 and achieve drying. Because water vapor has a lower density than air, it tends to be adsorbed in the upper part of the interlayer, while air automatically descends to the lower part, which facilitates air drying.

[0058] In one specific embodiment, the desiccant is silica gel or activated alumina. The air inlet membrane 26 is a PE breathable membrane or a PTFE membrane. Taking activated alumina as an example, commercially available activated alumina produced by Guohong Water Treatment Materials Company absorbs 250% of its weight in water vapor at 25°C and 90% relative humidity. Assuming an initial air RH of 80%, the initial moisture content is 23.01 x 80% (approximately 18.41 g / m³). 1 kg of activated alumina can absorb 2.5 kg of water vapor, equivalent to treating approximately 135 cubic meters (135,000 liters) of air. This reduces the frequency of activated alumina replacement. Furthermore, after high-temperature drying, activated alumina can expel moisture, restoring its moisture absorption capacity. This offers excellent economic benefits.

[0059] In one embodiment, an exhaust pipe 24 is provided above the exhaust port, the bottom end of which is connected to the exhaust port. The exhaust pipe 24 can quickly discharge water vapor from the A-shaped roof. In this embodiment, the exhaust pipe 24 provided at the exhaust port can guide the hot air carrying water vapor to quickly discharge, thereby preventing external air from flowing back into the interior of the pipe 11.

[0060] In a specific embodiment, the exhaust pipe 24 includes a venturi tube 241, the air inlet end of the venturi tube 241 is connected to the exhaust port, and the air outlet end of the venturi tube 241 is fixed with a cross bar 244, and the cross bar 244 is fixed to the pipe cover 242 above the cross bar 244 through a support rod 243. The diameter of the pipe cover 242 is larger than the diameter of the air outlet end of the venturi tube 241. There is a gap between the pipe cover 242 and the tube wall of the venturi tube 241, and the pipe cover 242 can block rainwater.

[0061] In a specific embodiment, the throat of the venturi tube 241 is connected to the closed interlayer through the first air pipe 22, and the venturi tube 241 can discharge the water vapor in the closed interlayer.

[0062] In this embodiment, the throat of the venturi tube 241 is connected to the enclosed interlayer. Because the throat of the venturi tube 241 creates a vacuum, it can extract some of the moisture within the enclosed interlayer. The outer panel 21 is black, and the heat absorbed by the outer panel 21 heats the desiccant 27, discharging a small amount of moisture from the desiccant 27 through the venturi tube 241. This extends the life of the desiccant 27.

[0063] In a specific embodiment, the vacuum assembly 3 includes a vacuum pump 31 and a second air pipe 32 .

[0064] The throat of the venturi tube 241 is also connected to the vacuum pump 31 through the second air pipe 32. In this embodiment, the vacuum pump 31 is provided to provide negative pressure at night or when there is insufficient sunlight to exhaust the air in the pipe 11 and ensure that dry air can enter the pipe 11.

[0065] In a specific embodiment, a spiral blade 14 is rotatably provided inside the pipe 11 , one end of the spiral blade 14 is connected to the motor 13 , a feed port is provided on the pipe 11 , and a hopper 12 is fixed on the feed port.

[0066] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
