[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] The following is in conjunction with the appendix Figure 1-4 The embodiments of this application will be described in further detail.

[0034] Example 1

[0035] A cylindrical grain dryer includes a support frame 1, a servo motor 4, an outer drying cylinder 5, a stirring rod 6, and an inner drying cylinder 7. The servo motor 4 is fixed to one end of the top of the support frame 1. The outer drying cylinder 5 is fixed to the side of the support frame 1 away from the servo motor 4, and the inner side of the outer drying cylinder 5 is hollow. One end of the stirring rod 6 is connected to the output end of the servo motor 4, which drives the stirring rod 6 to rotate. The inner drying cylinder 7 is located inside the outer drying cylinder 5, and its inner diameter is smaller than that of the outer drying cylinder 5. The inner side of a connecting assembly 9 is penetrated by one end of the stirring rod 6. The connecting assembly 9 includes... The inner wall of one end of the inner drying cylinder 7 is fixed with a docking ring 91, a hollow cavity 93 is opened inside the docking ring 91, and grooves 92 are opened at equal intervals on the inner wall of the hollow cavity 93. The docking assembly 11 includes a docking post 112 fixedly connected to the stirring rod 6, a protrusion 111 fixed around the outer wall of the docking post 112, and a rubber pad 113 fixed at the middle of one end of the docking post 112. The rubber pad 113 connects the docking post 112 and the stirring rod 6. There are six grooves 92 and six protrusions 111. The inner side of the groove 92 and the outer side of the protrusion 111 interlock with each other.

[0036] When using this embodiment, first refer to... Figure 1 As can be seen, the inner drying cylinder 7 is pushed into the inner side of the outer drying cylinder 5 in the direction of the arrow. When it is pushed into the inner side of the outer drying cylinder 5 in the direction of the arrow, the docking component 11 at one end of the stirring rod 6 passes through the middle position of the connecting component 9. During the pushing process, the protrusion 111 slides with the inner side of the groove 92 and locks when it slides to the end face. At this time, when the stirring rod 6 rotates, the inner drying cylinder 7 can be rotated at the same time by using the connecting component 9, so as to turn the grain placed inside the inner drying cylinder 7, which can improve the drying efficiency.

[0037] Example 2

[0038] The outer wall of the outer drying cylinder 5 is uniformly provided with second hollow holes 13, and the outer wall of the inner drying cylinder 7 is uniformly provided with first hollow holes 12. The inner diameter of the first hollow hole 12 is larger than the inner diameter of the second hollow hole 13, and the inner diameter of the second hollow hole 13 is smaller than the size of the grain particles. To further explain, since the inner diameter of the second hollow hole 13 is smaller than the size of the grain particles, the grain will not leak out through the second hollow hole 13 when the device is in use. The air is blown into the inner side of the outer drying cylinder 5 through the second hollow hole 13, thus achieving the purpose of drying. The dryer also includes a load-bearing horizontal plate 2 fixed to one side of the load-bearing frame 1, three sets of drying fans 3 fixed to the top of the load-bearing horizontal plate 2, a side cover 8 fixed to one end of the inner drying cylinder 7, and a support foot 10 fixed to the bottom of the load-bearing horizontal plate 2. The air outlet direction of the drying fans 3 is directly towards the outer drying cylinder 5. The drying fans 3 blow air into the outer drying cylinder 5, and the drying function is achieved during the blowing process.

[0039] The implementation principle of the drum-type grain dryer of this application is as follows:

[0040] The inner drying cylinder 7 is pushed into the inner side of the outer drying cylinder 5 in the direction of the arrow. When it is pushed into the inner side of the outer drying cylinder 5 in the direction of the arrow, the connecting component 11 at one end of the stirring rod 6 passes through the middle position of the connecting component 9. During the pushing process, the protrusion 111 slides against the inner side of the groove 92 and locks at the end face. When the stirring rod 6 rotates, the connecting component 9 can simultaneously drive the inner drying cylinder 7 to rotate, thereby turning over the grain placed inside the inner drying cylinder 7. This can improve the drying efficiency. At the same time, the second hollow hole 13 allows the air to blow into the inner side of the outer drying cylinder 5, thus achieving the purpose of drying. Furthermore, the rotation of the inner drying cylinder 7 during the rotation process can screen the grain placed inside the inner drying cylinder 7, adding a screening function while drying.

[0041] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
