The stirring circulation system is built into the silo system to transport the grain upwards and circulate it in the silo system.

[0003] At present, the inner cavity is a fixed structure without a stirring function; however, the lower part of the silo system is prone to clogging, resulting in poor circulation. Therefore, some drying machines in the existing structure will add a stirring system, such as the patent CN207515473U, which discloses a mobile grain dryer, which includes a silo system, a circulation system, a feeding system, a discharging system, a stirring system, a drying system, a dust removal system, a hydraulic system and a control system; characterized in that the silo system includes a bracket, a silo and an inner cavity, the circulation system includes a conveying auger and a main motor, the feeding system includes a feeding hopper, a feeding auger and a feeding motor, the discharging system includes a discharging pipe and a discharging valve, the stirring system includes a stirrer and a stirring transmission shaft, the drying system includes a biomass burner, an air supply fan and a heat exchanger, the dust removal system includes a dust removal sleeve, an exhaust fan and a dust collector, the hydraulic system includes a hydraulic pump, a hydraulic cylinder and a hydraulic motor, and the control system includes a control cabinet, a thermometer and a hygrometer.

[0004] However, the design of its stirring system is too complicated, the production cost is high, the structure is too complicated and not easy to maintain, and it only stirs the bottom material with a small stirring range, and has basically no stirring effect on the material deposited on the inner surface of the lower part of the outer cavity. Utility Model Content

[0005] The utility model provides a lower vertebral stirring structure of a grain dryer, which can solve the problems pointed out in the background technology.

[0006] A lower vertebral stirring structure of a grain dryer includes a rotating lower inner cavity and at least one group of stirring components arranged on the surface of the lower inner cavity. The lower inner cavity rotates axially when driven, driving the stirring components to stir the material outside the lower inner cavity. A driving connector and a rotary support are connected to the lower inner cavity. The driving connector is used for driving connection, and the rotary support provides rotational support. The stirring component includes a connector and an inclined toothed stirring plate.

[0007] Preferably, the toothed stirring plate is a mesh plate.

[0008] Preferably, the stirring assembly further comprises a vertical stirring plate located at the top.

[0009] Preferably, the connecting member is a plurality of connecting rods arranged along the height direction.

[0010] Preferably, the upper part of the lower inner cavity is connected to a rotating shaft via a connecting frame, and the driving connecting member and the rotating supporting member are both arranged on the rotating shaft.

[0011] Preferably, the driving connection member is a sprocket.

[0012] Preferably, the slewing support member is a slewing support bearing.

[0013] Preferably, the lower inner cavity is a conical lower inner cavity.

[0014] Beneficial effects: The utility model has a very simple structure, is convenient for agricultural and industrial production, is convenient for later maintenance, has a large stirring range, is also conducive to rapid drying, and can improve efficiency and product quality.

[0018] A specific implementation of the present utility model is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific implementation mode.

[0019] Example 1: Figure 1 As shown, an embodiment of the utility model provides a lower vertebral stirring structure of a grain dryer, comprising a rotating lower inner cavity 1 and at least one group of stirring components arranged on the surface of the lower inner cavity 1. The lower inner cavity 1 is driven to rotate axially, driving the stirring components to stir the material outside the lower inner cavity 1, that is, the material between the lower inner cavity 1 and the outer cavity is stirred, so that it can smoothly fall to the auger system at the bottom; in addition, by stirring the material in the lower inner cavity 1, the drying can also be accelerated and the drying efficiency can be improved.

[0020] The lower inner cavity 1 is connected to a driving connector 3 and a slewing support 4. The driving connector 3 is used for driving connection, and the slewing support 4 provides rotational support. The stirring assembly includes a connector 21 and an inclined toothed stirring plate 22. The toothed stirring plate 22 can better ensure the stirring effect. The toothed stirring plate 22 is connected to the lower inner cavity 1 through the connector 21, and the connector 21 is a plurality of connecting rods arranged along the height direction.

[0021] At present, the structure of the lower cavity is generally divided into an upper inner cavity and a lower inner cavity 1, which are welded together. The lower inner cavity 1 is generally conical. The conical structure facilitates the concentration of materials at the bottom of the auger. Therefore, in this embodiment, the lower inner cavity 1 is preferably a conical lower inner cavity.

[0022] Specifically, the toothed stirring plate 22 is a mesh plate, which facilitates the passage of hot air, making the drying airflow smoother and helping to improve the drying effect.

[0023] In some embodiments, in order to improve the stirring effect, the stirring assembly further includes a vertical stirring plate 23 located at the top.

[0024] Specifically, the upper part of the lower inner cavity 1 is connected to the rotating shaft 6 through the connecting frame 5, the driving connecting member 3 and the slewing support member 4 are both arranged on the rotating shaft 6, and the driving connecting member 3 is a sprocket. The slewing support member 4 is a slewing support bearing, and the slewing support bearing is connected to the upper inner cavity or the outer cavity through the mounting frame, that is, the slewing support bearing is fixed and stabilized by the mounting frame.

[0025] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
