Summary of the Invention

[0003] The object of the present invention is to provide an agricultural outdoor drying machine to solve the technical problem of easily generating drying dead corners.

[0004] To achieve the above-mentioned purpose, the specific technical solution of an agricultural outdoor drying machine of the present invention is as follows:

[0005] An agricultural outdoor dryer includes a drying box, a base, an upper end cover, a feed pipe, a heating pipe, a connecting pipe, a bellows, an executive motor 1, a transmission bevel gear 1, a transmission bevel gear 2, a rotating sleeve, a middle-end drive shaft, a hinged connecting rod, a driving rotating rod, an executive motor 2, a mounting bracket, an executive motor 3, a rotating sleeve, a fan blade, a discharge pipe, a discharge pipe end cover, a rotating limit ring, a material baffle, an opening, a stirring column and a rotating terminal. The upper end of the drying box is fixedly mounted with the upper end cover, the lower end of the drying box is fixedly mounted with the base, the heating pipe is mounted on the base, the heating pipe is mounted on one end of the connecting pipe, the other end of the connecting pipe is mounted on the bellows, the rotating sleeve is rotatably mounted on the bellows, the fan blade is mounted on the rotating sleeve, and there are multiple fan blades. The bellows is mounted with an executive motor 3, the output shaft of the executive motor 3 is mounted on the rotating sleeve, a material baffle is mounted in the heating pipe, the material baffle is opened with an opening, and there are multiple openings.

[0006] Furthermore, a rotating sleeve is rotatably installed on the upper end cover, and the rotating sleeve is rotationally limited by a rotating limit ring. A transmission bevel gear 2 is fixedly installed on the rotating sleeve, and the transmission bevel gear 2 is meshed with the transmission bevel gear 1 for transmission. The transmission bevel gear 1 is installed on the output shaft of the executing motor 1, and the executing motor 1 is installed on the upper end cover. A middle-end driving shaft is slidably installed in the rotating sleeve, and a rotating terminal is rotatably installed on the middle-end driving shaft. The rotating terminal is hingedly installed on one end of the hinged connecting rod, and the other end of the hinged connecting rod is hingedly installed on the driving rotating rod. The driving rotating rod is rotatably installed on the mounting bracket, and the mounting bracket is fixedly installed on the upper end cover. The executing motor 2 is installed on the mounting bracket, and the output shaft of the executing motor 2 is installed on the driving rotating rod. A stirring column is installed on the middle-end driving shaft, and a plurality of stirring columns are provided.

[0007] Furthermore, a plurality of the stirring columns are arranged in a circumferential array along the central axis of the middle end driving shaft.

[0008] Furthermore, the plurality of openings are arranged in a linear array along the material baffle.

[0009] Furthermore, the plurality of blades are arranged in a circumferential array along the central axis of the rotating sleeve.

[0010] Furthermore, a feed pipe is fixedly installed on the upper end cover.

[0011] Furthermore, a discharge pipe is installed at the lower end of the drying box body, and a discharge pipe end cover is threadedly installed on the discharge pipe.

[0012] Furthermore, an air heating device is installed in the heating tube, and the model of the heating device is FYL-YS-151L.

[0013] Furthermore, a groove A is formed on the rotating sleeve, and a rectangular slider A is provided on the middle end driving shaft, and the rectangular slider A is slidably matched with the groove A.

[0014] The advantages of the present invention are:

[0015] 1. The small granular crops to be dried are put into the upper end cover through the feed pipe, and the executive motor 3 is started. The executive motor 3 drives the fan blades to rotate by rotating the sleeve. The fan blades blow the outside air into the heating tube through the connecting pipe. The air is heated by the heating device in the heating tube, causing the hot air to flow into the drying box. The hot air contacts the small granular crops in the drying box, achieving drying of the small granular crops. When drying is completed, the dried small granular crops are recovered through the discharge pipe. At the same time, the material baffle blocks the small granular crops.

[0016] 2. With the accumulation of small granular crops, the middle of the small granular crops cannot be fully exposed to the hot air, resulting in a poor drying effect on the middle position of the small granular crops. The execution motor 1 is started, and the execution motor 1 drives the rotating sleeve to rotate through the meshing transmission between the transmission bevel gear 1 and the transmission bevel gear 2. The groove A on the rotating sleeve slides with the rectangular slider A on the middle-end drive shaft, so that the middle-end drive shaft drives the stirring column to rotate. At the same time, the execution motor 2 is started, and the execution motor 2 drives the driving rod to rotate. The rotating motion drives the rotating rod to drive the axial reciprocating motion of the middle-end drive shaft through the hinged connecting rod and the rotating terminal, and drives the stirring column on the middle-end drive shaft to rotate and reciprocate up and down at the same time. The rotating motion and up and down reciprocating motion of the stirring column achieve stirring of the small granular crops. During the stirring process, a certain gap will be generated in the small granular crops, which facilitates the influx of hot air, thereby achieving drying of the middle end of the small granular crops and avoiding the formation of drying dead corners.
