[0021] like Figures 1-4 As shown, an automatic wheat dryer includes a wheat placement rack 1, which has an open box-like structure for holding wheat to be dried. Support plates 2 are symmetrically installed at the top and bottom of the wheat placement rack 1. Between the front and rear support plates 2, identical rotating rollers 3 are symmetrically installed vertically. A conveyor belt 4 is fitted onto the rotating rollers 3, and several buckets 5 are equidistantly installed on the outer side of the conveyor belt 4. One end of each rotating roller 3 extends through the support plate 2 and is connected to a drive wheel. The drive wheel is driven to rotate by a conveyor motor 6. As the drive wheel rotates, the conveyor belt 4 conveys the wheat vertically, transporting it from bottom to top. As the buckets 5 follow the conveyor belt 4, they transport the wheat from the placement rack 1 to a higher position, thus achieving automatic wheat feeding.

[0022] A drum dryer 7 is installed on the right side of the wheat placement rack 1. A feed hopper 8 is located on the upper left side of the drum dryer 7. An inclined guide plate 9 is installed on the feed hopper 8, extending towards the conveyor belt 4. That is, after the wheat on the bucket 5 reaches a high point, it falls freely in a parabolic motion as the bucket 5 no longer restrains it, eventually landing on the guide plate 9 and entering the feed hopper 8. During this process, some wheat that does not reach the guide plate 9 falls back onto the wheat placement rack 1 and is again transported to the feed hopper 8 by the bucket 5. This ensures transportation efficiency, frees up labor, and allows for controllable feeding quantity and speed, achieving automated feeding.

[0023] The inside of the drum dryer 7 is provided with a stirring device, which comprises a stirring device inside the drum dryer 7 and is connected with a stirring motor 10 after passing through the drum dryer 7. The outer wall of the drum dryer 7 is provided with a driving rotating device, and the two sides of the driving rotating device are provided with symmetrically distributed supporting rotating devices. The driving rotating device comprises a large gear 11 installed on the outer periphery of the drum dryer 7, the large gear 11 is engaged with a small gear 12, the center position of the small gear 12 is connected with a rotating shaft by a key, the rotating shaft is connected with a speed reduction mechanism, and the speed reduction mechanism is connected with a motor 13; the small gear 12 and the motor 13 are located on one side of the drum dryer 7. The supporting rotating device comprises a sliding rail 14 installed on the outer periphery of the drum dryer 7, symmetrically installed rollers 15 below the sliding rail 14, and the sliding rail 14 and the rollers 15 are in contact connection; the rollers 15 are directly installed in a limiting groove 16, and the sliding rail 14 is slidably installed in the limiting groove 16.

[0024] Specifically, after the wheat is sent into the drum dryer 7, the stirring device is started to stir the wheat, so as to avoid the accumulation of the wheat affecting the drying efficiency and quality; at the same time, the motor 13 is started, the small gear 12 rotates, and the large gear 11 engaged with the small gear 12 rotates together, thereby realizing the rotation of the drum dryer 7 and driving the wheat inside to roll; when the drum dryer 7 rotates, the sliding rail 14 rotates on the rollers 15, which serves to assist the rotation, and the limiting groove 16 avoids the axial movement of the drum dryer 7 during rotation, thereby ensuring the rotation stability and safety of the drum dryer 7. In addition, in order to shorten the drying time, heating fins can be appropriately installed on the outer wall of the drum dryer 7 without damaging the nutritional value of the wheat, and the temperature thereof is adjusted to about 50℃, which can ensure uniform drying and avoid the problems of darkening of the wheat color, deterioration of the taste or burning of the wheat.

[0025] A discharging cavity 18 is installed on the right side of the drum dryer 7, a discharging port 17 is installed at the bottom of the discharging cavity 18, a grid baffle 19 is installed on the right side wall of the discharging cavity 18, which blocks the wheat and allows it to fall into the discharging port 17 below under the action of the grid baffle 19, thereby realizing automatic discharging. A filtering cavity 20 is installed on the right side of the discharging cavity 18, a plurality of filter screens are installed in the filtering cavity 20, and the right side of the filtering cavity 20 is connected with a fan 21 through a wind cylinder, so that the filter screens can prevent impurities from entering the inside of the fan 21 and affecting the operation of the fan 21.

[0026] The fan 21 is connected with a fan motor through a transmission mechanism 22, the transmission mechanism 22 comprises a driven wheel connected with the central shaft of the fan 21 and a driving wheel connected with the output shaft of the fan motor, and the driving wheel and the driven wheel are connected through a transmission belt. The wind speed generated by the fan 21 is adjusted by the rotating speed of the fan motor, when drying, the wind of the fan 21 drives the air circulation, and does not mainly drive the wheat flow, mainly for the air to take away the moisture of the wheat seeds; when discharging, the wind is increased, the wind drives the wheat to flow from the cylinder air dryer 7, and finally falls in the discharging port 17.

[0027] The action process of the utility model is as follows:

[0028] Firstly, the fan 21 is started, air flow is driven, that is, the outside air is introduced into the cylinder air dryer 7 from the feeding hopper 8, then passes through the filter cavity 20 and the air cylinder in turn and is finally discharged; then, the conveying motor 6 is started, the wheat is transported to a high place under the action of the shovel 5 on the conveying belt 4 and is introduced into the guide plate 9 and then slides into the feeding hopper 8; after that, the stirring device and the motor 13 are started, the cylinder air dryer 7 is rotated under the action of the pinion 12 and the gear wheel 11 engaged with the pinion 12, and cooperates with the stirring device to stir the wheat in the cylinder air dryer 7; finally, the flowing air takes away the moisture of the continuously rolling wheat, until the wheat is dried, the wind force of the fan 21 is increased, under the driving of the wind, the wheat flows into the discharging cavity 18, due to the blocking action of the grid baffle 19, the wheat is finally discharged from the discharging port 17.

[0029] The above-described embodiment is only used for describing the preferred mode of the utility model, and does not limit the scope of the utility model, under the premise that the design spirit of the utility model is not departed from, various deformations and improvements of the technical scheme of the utility model made by the ordinary skilled in the art should fall into the protection scope determined by the claim of the utility model.
