As shown in fig. 16, the connection method of the body segment BT is first described.

The body component S1 is arranged at the head of a body rubber tube L1, and the body spiral piece K1 in the body rubber tube L1 is directly welded and connected with the body welding end face 311 of the body head 3. Then, the first body cylinder 21 is inserted into the head of the body hose L1 and locked by a hoop 13. Finally, the plug 12 is placed on the head of the body assembly S1, and the plug 12 is fixed on the head of the body assembly S1 by using the connecting internal thread 222 connecting the external thread 124 and the second body barrel 22, so as to obtain the body section BT, as shown in fig. 17.

In fig. 16 and 17, only a part of the body hose L1 and the body spiral sheet K1 are shown. The far end of the body rubber tube L1 is directly connected with a grain collecting bin, and the far end of the body spiral sheet K1 is connected with an output shaft of a driving motor.

When grain is sucked, the driving motor is started, the body spiral sheet K1 rotates in the body rubber tube L1 along the direction R, meanwhile, the body head 3 of the body assembly S1 also rotates along with the body spiral sheet K1, and grain enters the body rubber tube L1 from the opening M1 between the first body cylinder 21 and the second body cylinder 22 along the direction F1 and is conveyed to a far-end grain collecting bin.

It should be noted that, at this time, the plug 12 is not an essential component, and is used to facilitate insertion of the body section BT into the grain pile, and also to protect the hook 24 on the second body cylinder 22. When the grain sucking device does not need to be prolonged, the grain sucking can be completed only through the body section BT.

The manner of connection of the extension YC is described below.

As shown in fig. 18, an extension rubber tube L2 of a predetermined length is taken, and an extension screw K2 is provided in the extension rubber tube L2. The length of the extension hose L2 may be set to a standard length, such as 10 meters.

Next, a body assembly S1 is disposed at the head of the extension hose L2, an extension assembly S2 is disposed at the tail of the extension hose L2, the head of the extension screw sheet K2 is welded to the body welding end face 311 of the body head 3 of the body assembly S1, and the tail of the extension screw sheet K2 is welded to the extension welding end face 611 of the extension head 6 of the extension assembly S2.

Next, the first body cylinder 21 of the body assembly S1 is inserted into the head of the extension hose L2, and the first extension cylinder 51 of the extension assembly S2 is inserted into the tail of the extension hose L2 and is locked by a respective anchor 13. Finally, an extension YC is obtained, as shown in fig. 19. When the extension head 6 of the extension assembly S2 rotates, the extension head 6 rotates the extension screw sheet K2, and thus the body head 3 of the body assembly S1 rotates.

The combination of the body section BT and the extension section YC is described below.

As shown in fig. 20, the plug 12 of the body section BT is first unscrewed.

Next, the extension section YC is placed on the head of the body section BT, and the extension section YC and the body section BT are abutted along the direction F2 by using the hook head 54 of the extension section YC and the hook seat 24 on the body section BT, and the hook head 54 and the corresponding hook seat 24 are locked.

The unscrewed plug 12 is then screwed again to the head of the extension YC.

Then, two sealing sleeves S3 are taken, and the opening of the body section BT and the opening of the tail of the extension section YC are sealed. Finally, the connection of the body section BT and the extension section Y is completed as shown in fig. 21.

It should be noted that, when the extension sections YC and BT are docked, the body clamping groove 34 of the body head 3 needs to be aligned with the extension clamping bar 64 of the extension head 6.

When grain is sucked, the driving motor is started, the body head 3 in the body section BT rotates, the body spiral section 33 of the body head 3 drives the extension thread section 63 of the extension head 6 of the extension section YC, then the extension head 6 of the extension section YC rotates, and then the body head 3 of the extension section YC rotates. Finally, grains sequentially enter the extension rubber tube L2 and the body rubber tube L1 along the direction F3 from the opening M2 of the head part of the extension section YC and are conveyed to a grain collection bin at the far end.

The user can select the quantity of the extension sections YC as required to easily realize long-distance grain sucking operation, the combination is simple and convenient, and the operation is convenient.

Without being limited thereto, any changes or substitutions that are not contemplated by the inventors are intended to be included within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
