[0015] Please see Figs. 1 to 3 The embodiments of this utility model include:

[0016] A high-efficiency and energy-saving agricultural drying equipment includes a drying drum 1, an umbrella-shaped cover 2, a funnel cover 3, a spiral auger 4, a conveying pipe 5, a drive motor 6, and a heating component 7. The top of the drying drum 1 is a feed inlet 11, and the bottom is a conical slope 12. The conveying pipe 5 passes through the bottom of the drying drum 1 and is fixedly connected to it. The bottom of the conveying pipe 5 is a closed end, and the top is an open end. The spiral auger 4 is rotatably connected inside the conveying pipe 5. The drive motor 6 is fixedly connected to the bottom end of the conveying pipe 5. The output shaft of the drive motor 6 passes through the conveying pipe 5 and is fixedly connected to the spiral auger 4. The conveying pipe 5 has a conveying port 51 at the bottom of the drying drum 1 and a discharge port 52 at the bottom end of the conveying pipe 5 outside the drying drum 1. Two sets of funnel covers 3 are axially arranged on the inner wall of the drying drum 1, and two sets of umbrella-shaped covers 2 are axially arranged on the outer wall of the conveying pipe 5. The umbrella covers 2 and the funnel covers 3 are staggered. The bottom of the funnel cover 3 has multiple hot air vents 13 that communicate with the heating component 7.

[0017] The heating assembly 7 includes a fan 71, a heating plate 72, and an air collecting hood 73. The air collecting hood 73 is installed on the outer wall of the drying barrel 1 and covers the hot air outlet 13 inside. The fan 71 is fixedly connected to the outside of the drying barrel 1. The air outlet of the fan 71 is connected to the air collecting hood 73 through a flexible hose. The heating plate 72 is installed inside the air collecting hood 73 for heating the air.

[0018] The umbrella-shaped cover 2 and the funnel-shaped cover 3 are made of metal.

[0019] A door panel 8 for sealing is provided at the discharge port 52 at the bottom end of the conveying pipe 5;

[0020] With the above settings, its specific working principle in actual operation is as follows:

[0021] First, put the grain that needs to be dried into the feed inlet 11 of the drying drum 1. At this time, the grain falls to the bottom of the drying drum 1 under the action of gravity.

[0022] Then, the heating component 7 and the drive motor 6 are started simultaneously. The drive motor 6 drives the spiral auger 4 to rotate forward. The grain that falls to the bottom of the drying drum 1 enters from the conveying port 51 of the conveying pipe 5 and is conveyed out from the top of the conveying pipe 5 under the drive of the spiral auger 4. The output grain falls to the bottom of the drying drum 1 again under the action of gravity. During this process, the grain will slide off the surface of the umbrella cover 2 and the funnel cover 3 multiple times, thereby achieving the effect of scattering grain.

[0023] The fan 71 in the heating assembly 7 blows high-pressure airflow into the air collecting hood 73. The airflow entering the air collecting hood 73 is heated by the heating plate 72. The heated hot air is blown into the drying drum 1 through the hot air outlet 13. Since the hot air outlet 13 is located at the bottom of the funnel hood 3, when the hot air blows into the drying drum 1, it can also heat the umbrella hood 2 and the funnel hood 3 at the same time to dry the grain. During the process of the grain falling to the bottom of the drying drum 1, the hot air can fully contact the grain, thereby accelerating the drying speed of the grain.

[0024] After drying is completed, open the door panel 8 at the bottom of the conveying pipe 5, and then start the drive motor 6 to drive the spiral auger 4 to reverse, so that the grain that has fallen to the bottom of the drying barrel 1 enters from the conveying port 51 of the conveying pipe 5 and is conveyed out from the bottom discharge port 52 under the drive of the spiral auger 4.

[0025] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
