When the air-locking shaft support device provided by the present invention is in use, the mounting plate 1 is first connected to the air-locking side plate of the leaf-threshing and redrying blanking device, and then the lateral position of the support adjustment mechanism 3 is adjusted on the support plate 2 so that it is located directly below the air-locking shaft. Secondly, the longitudinal height of the support adjustment mechanism 3 is adjusted so that the rotation adjustment structure is close to the position of the air-locking shaft. Finally, the rotation adjustment mechanism 4 is adjusted and fine-tuned so that the rotation adjustment mechanism 4 can support the air-locking shaft. Through the above-mentioned arrangement, the present invention enables the operator to conveniently adjust the height of the support adjustment mechanism 3 and the angle of the rotation adjustment mechanism 4 according to needs to support the air-locking shaft.

[0058] In the air lock shaft support device provided by the utility model, refer to Figures 1 to 3 The support adjustment mechanism 3 includes a first driving member 31 slidably connected to the support plate 2 and a support rod 32 connected to the drive shaft of the first driving member 31. The rotation adjustment mechanism 4 is provided at the top of the support rod 32. For illustration, the first driving member 31 can be selected from any one of a stepping motor, a DC reduction motor or a servo motor, preferably a servo motor. The first driving member 31 can slide laterally on the support plate 2 to position the lateral position of the air lock shaft, and can also extend or shorten its drive shaft to adjust the longitudinal height of the support rod 32 to position the longitudinal height of the air lock shaft. In a specific embodiment, the first driving member 31 is a sleeve, and the support rod 32 is provided in the sleeve and is threadedly connected to the sleeve. When in use, the height of the support rod 32 can be raised or lowered by rotating the support rod 32.

[0059] In the air lock shaft support device provided by the utility model, refer to Figure 1 and Figure 2 , the support plate 2 is provided with a through slot 21 in the same direction as the extension of the support plate 2, and the first driving member 31 is vertically provided in the through slot 21 and is slidably connected to the through slot 21. The first driving member 31 is provided with a fixing rod 33 in the same direction as the extension of the through slot 21 on the side away from the mounting plate 1, and a part of the fixing rod 33 is located outside the through slot 21, and the fixing rod 33 is suitable for driving the first driving member 31 to move along the extension direction of the through slot 21. The support plate 2 is provided with a fixing block 22 at one end away from the mounting plate 1, and the fixing block 22 is detachably connected to the fixing rod 33. As an illustration, the connection relationship between the fixing rod 33 and the through slot 21 is similar to that of an injection syringe, and the fixing rod 33 can be pulled outward or pushed inward in the through slot 21. At this time, the first driving member 31 will follow the fixing rod 33 to move inward or outward, thereby realizing the movement of the first driving member 31 in the through slot 21. In a specific embodiment, refer to Figure 4 The fixing block 22 is provided with a fixing block opening 22.1, and the fixing rod 33 is provided with a plurality of fixing rod openings 33.1 arranged in sequence along the extending direction of the fixing rod 33.

When adjusting the lateral position of the first driving member 31, the fixing rod 33 can be pulled outward or pushed inward. Since the fixing rod 33 is connected to the first driving member 31, the first driving member 31 will move outward or inward with the fixing rod 33. When the first driving member 31 is directly below the air lock shaft, the lateral position of the first driving member 31 is determined. At this time, the fixing rod opening 33.1 on the fixing rod 33 closest to the fixing block 22 is found, and the lateral position of the first driving member 31 is slightly corrected so that the fixing rod opening 33.1 is aligned with the fixing block opening 22.1. Finally, the fixing screw 34 is inserted into the fixing rod opening 33.1 and the fixing block opening 22.1 to complete the fixation. Furthermore, a handle 33.2 is provided on one end of the fixing rod 33 outside the through slot 21. The handle 33.2 facilitates the operator to pull outward or push inward the fixing rod 33. This arrangement allows the operator to easily adjust the lateral position and longitudinal height of the support adjustment mechanism to position the air lock shaft as needed, thereby improving the applicability of the present invention.

The limit block 31.1 is arranged in the limit slot 21.1 and is slidably connected to the limit slot 21.1. For illustration, the cross-sectional shapes of the through slot 21 and the limit slot 21.1 can be referred to Figure 6 Similar to the T-shaped blocks in Tetris, the function of the limit slot 21.1 is to limit the support rod 32, preventing the support rod 32 from accidentally falling out when moving in the through slot 21, thereby improving the safety of the present invention. Generally speaking, the extension length of the limit slot 21.1 is smaller than the through slot 21 to ensure that the support rod 32 is not pulled too far and thus pulled out of the through slot 21.

[0061] In the air lock shaft support device provided by the utility model, refer to Figure 2 、 Figure 5 and Figure 7 The rotation adjustment mechanism 4 includes a rotor 41 provided on the top of the support adjustment mechanism 3 and capable of rotating about the axis of the support adjustment mechanism 3, an adapter block provided on the outside of the rotor 41, and a support frame 43 connected to the adapter block; a bracket 43.1 suitable for supporting the air lock shaft is provided on the top of the support frame 43. For illustration, the rotor 41 is spherical in shape, a groove is provided in the rotor 41, and the top of the support rod 32 is provided in the groove. Preferably, the top of the support rod 32 is a dome. When in use, the rotor 41 is rotated, the adapter block will rotate with the rotor 41, and the support frame 43 will also rotate with the adapter block until the extension direction of the bracket 43.1 in the support frame 43 matches the extension direction of the air lock shaft. Through the above arrangement, the operator can easily adjust the rotation position of the bracket 43.1 to match the direction of the air lock shaft according to needs, thereby improving the applicability of the present utility model.

Generally speaking, the length of the tripods 31.3 can also be extended or stretched. When in use, the tripods 31.3 are spread out like a camera tripod and stretched until they can stably contact the ground to provide longitudinal support for the first driving member 31.

[0065] The utility model also provides a method for using the air-lock shaft support device of the leaf threshing and redrying blanking device, which is specifically described as follows:
