[0029] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0030] Embodiment 1:

[0031] like Figure 1-5 As shown, a grain drying device capable of continuous feeding includes a drying barrel 2 supported on the ground by supporting legs 1 and a continuous feeding assembly 4 arranged on one side of the drying barrel 2.

[0032] A drying assembly 3 is arranged on the outside of the drying barrel 2, the top and bottom of the drying barrel 2 are respectively fixedly connected and communicated with a feed hopper 11 and a discharge pipe 10, a partition 7 is fixedly connected to the inner wall of the drying barrel 2, a rotating shaft 5 is rotatably connected to the inner wall of the partition 7, a plurality of radially arranged arc-shaped material-selecting plates 6 are fixedly connected to the outer wall of the rotating shaft 5, a plurality of leakage holes are opened on the inner wall of the partition 7, and a motor 8 is fixed to the bottom of the partition 7 by bolts, and the output shaft of the motor 8 is fixedly connected to the rotating shaft 5 through a coupling.

[0033] The starting motor 8 drives the rotating shaft 5 to drive the arc-shaped material-discharging plate 6 to rotate, and then the continuous feeding component 4 is used to transport the grain to be dried to the feed hopper 11. The grain enters the drying barrel 2 through the feed hopper 11. Due to the obstruction of the partition 7, the grain will fall to the surface of the partition 7. The rotation of the arc-shaped material-discharging plate 6 drives the grain to fall from the leakage hole on the partition 7 in the shape of "raindrops". During the falling of the grain, the drying component 3 dries the grain.

[0034] The device is provided with an arc-shaped material-shifting plate 6 and a partition 7. When grains enter the drying barrel 2, they are blocked by the partition 7 and fall to the top surface of the partition 7. The rotation of the arc-shaped material-shifting plate 6 can drive the grains to fall from the leakage holes in the shape of "raindrops", thereby breaking up the grains, increasing the gaps between the grains, and improving the drying efficiency and quality.

[0035] In this embodiment, a heating wire is arranged inside the partition 7. The partition 7 is heated by the heating wire, so as to preheat the grains, increase the temperature of the grains themselves, and thus accelerate the drying efficiency.

[0036] The drying component 3 includes an annular tube 12, an air supply pipe 13 and a heat pump 14. The annular tube 12 is fixedly connected to the circumferential outer wall of the drying barrel 2 through a connecting pipe 9. The heat pump 14 is fixedly connected to the outer wall of the drying barrel 2 through a supporting plate 15. The output end of the heat pump 14 is connected to the annular tube 12 through the air supply pipe 13.

[0037] The heat pump 14 is started to extract external air, and the heated gas is transported to the annular tube 12 through the air supply pipe 13. The annular tube 12 transports the gas to the drying barrel 2 through multiple connecting pipes 9, thereby heating and drying the falling grains in the drying barrel 2.

[0038] In this embodiment, the continuous feeding assembly 4 includes a hollow cylinder 20 supported on the ground by a bracket 16, and the hollow cylinder 20 is arranged at an angle.

[0039] The upper side of the bottom end of the hollow cylinder 20 is welded and connected to the second feed hopper 18, and the lower side of the top end of the hollow cylinder 20 is welded and connected to the discharge pipe 22, which is located above the first feed hopper 11.

[0040] The inner wall of the hollow cylinder 20 is rotatably connected with a spiral blade 19 via a second rotating shaft 21, and a second motor 17 is fixed to the side wall of the bottom end of the hollow cylinder 20 via bolts, and the output end of the second motor 17 is fixedly connected to the spiral blade 19 via a coupling.

[0041] The second motor 17 is started to drive the second shaft 21 to drive the spiral blade 19 to rotate, thereby transporting the grain upward, and the grain falls into the first feed hopper 11 through the discharge pipe 22.

[0042] In this embodiment: when it is necessary to dry the grain, start the motor 2 17 to drive the rotating shaft 2 21 to drive the spiral blade 19 to rotate, thereby transporting the grain upward, and the grain falls into the feed hopper 11 through the discharge pipe 22. The grain enters the drying barrel 2 through the feed hopper 11. Due to the obstruction of the partition 7, the grain will fall to the surface of the partition 7, and the partition 7 is heated by the electric heating wire to preheat the grain and increase the temperature of the grain itself. At the same time, the motor 18 drives the rotating shaft 15 to drive the arc-shaped material-dispensing plate 6 to rotate. The rotation of the arc-shaped material-dispensing plate 6 drives the grain to fall from the leakage hole on the partition 7 in the shape of "raindrops". During the falling of the grain, start the heat pump 14 to extract external gas, heat the gas and then transport it to the annular tube 12 through the air supply pipe 13. The annular tube 12 transports the gas to the drying barrel 2 through multiple connecting pipes 9, thereby heating and drying the falling grain in the drying barrel 2. The dried grain is discharged through the discharge pipe 10 under the action of gravity.

[0043] Embodiment 2:

[0044] A grain drying device capable of continuous feeding, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 1-5 As shown:

[0045] The motor 1 8 , the heating wire, the heat pump 14 and the motor 2 17 are connected in parallel in the same power supply circuit.

[0046] In this embodiment: when the feeding speed is faster, the rotation speed of motor 2 17 is faster, and the power of motor 1 8, heating wire and heat pump 14 are all increased, thereby ensuring that the feeding speed, heating power and feeding speed are interrelated to ensure the grain drying effect.

[0047] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
