Compared with vertical mobile dryer, horizontal mobile dryer is lower in height and can be used in environments with height restrictions.

[0050] Working principle of the present invention:

[0051] When the present invention is in use, first, crops are added to the drying drum 2 through the discharge port 11, and then the servo motor 6 and the hot air blower 3 are turned on. The servo motor 6 drives the driving wheel 23 to rotate. During the rotation of the driving wheel 23, the driving ring 24 is driven to rotate, so that the driving ring 24 can effectively drive the drying drum 2 to rotate. During the rotation of the drying drum 2, the spiral plate 17 inside it will also rotate with the rotation of the drying drum 2, thereby driving the crops inside the drying drum 2 to move toward the direction close to the work-shaped part 5.

[0052] After the hot air blower 3 is turned on, the hot air blower 3 will transport hot air to the work-shaped member 5 through the input pipe. After entering the work-shaped member 5, the hot air will be blown into the drying cylinder 2 through the inclined air holes 20. After entering the drying cylinder 2, the hot air will blow on the crops in the drying cylinder 2, and the hot air will be used to achieve the purpose of drying the crops. During the drying process, since the drying cylinder 2 is in a rotating state, the drying cylinder 2 will turn over the crops inside it so that the crops are heated evenly. At the same time, the spiral plate 17 will carry part of the crops to the top of the drying cylinder 2 and then fall. During the falling process of the crops, the hot air blown out by the hot air blower 3 can further contact the crops, thereby achieving the purpose of drying the crops.

[0053] After the crops are harvested, dust or shells will adhere to their surface. The hot air blown by the hot air blower 3 can effectively blow out the dust or shells during the rotation of the drying drum 2, so that the dust or shells can be discharged through the discharge port 11, so that there are fewer impurities in the dried crops. At the same time, it can also effectively avoid the situation where the crop drying efficiency is reduced due to excessive impurities. By discharging impurities, the impurities are prevented from absorbing the heat in the hot air blown by the hot air blower 3. It should be noted that the shell is specifically a shell wrapped around the outside of the crops. Taking wheat ears as an example, it is specifically the epidermis wrapped around the outside of the wheat grains.

[0054] When the servo motor 6 is turned on, the first air pump 14 and the second air pump 16 are also turned on. After the second air pump 16 is turned on, air will be blown into the chute. After the gas enters the chute, it will push the sliding plate 25 upward, so that the sliding plate 25 drives the mounting frame 22 to move upward through the connecting column 26, and then the mounting frame 22 drives the cleaning cotton plate 21 to abut against the outer wall of the drying cylinder 2, so that the cleaning cotton plate 21 wipes the outer wall of the drying cylinder 2, which is beneficial to avoid dust or crop shells adhering to the outer wall of the drying cylinder 2, and is beneficial to maintaining the cleanliness of the drying cylinder 2.

[0055] Secondly, through the setting of the first water tank 7, in the process of the cleaning cotton plate 21 abutting against the outer wall of the drying drum 2, the water in the first water tank 7 can effectively enter the installation frame 22 through the rubber tube 27. In this process, the principle of the communicating vessel is utilized. When the water in the installation frame 22 is lower than the highest end of the connection between the rubber tube 27 and the first water tank 7, the gas in the outside atmosphere will enter the first water tank 7, and then the water in the first water tank 7 will enter the installation frame 22 for replenishment. This technology is a prior art and is commonly used in drinking water for poultry, so it will not be disclosed in detail here.

[0056] After the water in the first water tank 7 enters the installation frame 22, it will soak the cleaning cotton board 21 in the installation frame 22, thereby making the cleaning cotton board 21 moist. After the cleaning cotton board 21 is moistened, the dust on the outer wall of the drying cylinder 2 can be further cleaned, and the outer wall of the drying cylinder 2 can also be wetted. By wetting the outer wall of the drying cylinder 2, the drying cylinder 2 can also be cooled down.

[0057] As the second air pump 16 works, the second air pump 16 will gradually increase the air pressure in the chamber below the sliding plate 25 in the chute. When the air pressure rises to the preset pressure value of the first air pressure valve 28, the first air pressure valve 28 opens to discharge the excess gas in the first air pressure valve 28, and the discharged gas enters the built-in groove 30 through the built-in pipe 29, and finally blows on the outer wall of the drying cylinder 2 through the exhaust nozzle 15. After the gas blows on the outer wall of the drying cylinder 2, it will accelerate the evaporation of water on the outer wall of the drying cylinder 2, and further improve the cooling effect of the drying cylinder 2, which is conducive to avoiding the occurrence of burnt crops inside the drying cylinder 2 during the drying process due to the excessive temperature of the drying cylinder 2. The initial cooling of the outer wall of the drying cylinder 2 by the cleaning cotton board 21 will also apply water to the outer wall of the drying cylinder 2, and the water will be evaporated by the exhaust nozzle 15. The evaporation of water will absorb heat, and thus the cooling efficiency of the drying cylinder 2 can be improved.

[0058] After the first air pump 14 is turned on, it will blow air into the second water tank 12, thereby increasing the air pressure in the second water tank 12, and using the high pressure to make the water in the second water tank 12 enter the connecting water pipe 10. After entering the connecting water pipe 10, the water will enter the box body 9, and finally be sprayed through the atomizing nozzle 18. The water mist sprayed by the atomizing nozzle 18 can, on the one hand, reduce dust on the outside of the discharge port 11 on the drying cylinder 2, which is beneficial to prevent the dust and crop shells discharged from the discharge port 11 from falling on the outer wall of the drying cylinder 2, thereby causing the outer wall of the drying cylinder 2 to be contaminated. On the other hand, the hot air discharged from the drying cylinder 2 can be cooled by spraying water mist, which is beneficial to prevent the outside of the drying cylinder 2 from being overheated.

[0059] By setting the baffle plate 8, on the one hand, the gas exhausted from the drying drum 2 can move obliquely downward, which is beneficial to limit the dust exhausted from the drying drum 2 with the airflow from diffusing into the air, thereby causing excessive content of particulate dust in the air; on the other hand, it can also effectively prevent the water mist sprayed by the atomizing nozzle 18 from entering the discharge port 11, thereby preventing the water mist sprayed by the atomizing nozzle 18 from entering the discharge port 11, thereby preventing the crops from being effectively dried.

[0060] As the first air pump 14 works, the air pressure in the second water tank 12 will increase. When the air pressure in the second water tank 12 increases to the preset air pressure value of the second air pressure valve 33, the second air pressure valve 33 opens, allowing the gas in the second water tank 12 to enter the exhaust pipe 13, and then blow to the side of the servo motor 6 through the exhaust pipe 13 to achieve the purpose of dissipating the heat of the servo motor 6, which is beneficial to avoid overheating of the servo motor 6. At the same time, the gas will pass through the second water tank 12, and the humid air in the second water tank 12 can be used to further reduce the temperature of the gas during the flow process, thereby improving the effect of the airflow on dissipating heat and cooling the servo motor 6.

[0061] After the crops are dried, the first air pump 14 is turned off, and the vehicle body 1 is pulled to the storage area of ​​the crops, and then the servo motor 6 is controlled to rotate in the opposite direction. During the reverse rotation of the servo motor 6, the drying cylinder 2 and the spiral plate 17 inside it can be driven to rotate in the opposite direction. The rotation of the spiral plate 17 can effectively discharge the crops in the drying cylinder 2. At the same time, the gas blown out by the hot air blower 3 can also help blow out the crops in the drying cylinder 2, so that the drying cylinder 2 can discharge the crops more thoroughly. It should be noted that after the first air pump 14 is turned off, the atomizing nozzle 18 will stop spraying water mist, which is helpful to avoid the atomizing nozzle 18 from wetting the dried crops.

[0062] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention.
