DETAILED DESCRIPTION

[0033] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0034] Example:

[0035] like Figures 1 to 5 As shown, in order to solve the above problems, this embodiment discloses a spiral assembly, including a conveying pipeline 10, a spiral conveying structure 20 and a driving structure 30, wherein the spiral conveying structure 20 is rotatably disposed in the conveying pipeline 10 for conveying materials, and the driving structure 30 is disposed at one end of the conveying pipeline 10 for driving the spiral conveying structure 20;

[0036] The spiral conveying structure 20 includes at least one pair of tubular rotating shafts 200, each of which is provided with a spiral conveying blade 201, and the conveying blade 201 is fixedly connected to the rotating shaft 200. A fixed connecting member 202 is provided between the pair of rotating shafts 200, and the fixed connecting member 202 is used to connect the pair of rotating shafts 200. The fixed connecting member 202 includes a first fixed ring body 203, a first fixed blade 204, a second fixed ring body 205, a second fixed blade 206 and an insertion rod 207;

[0038] Compared with the traditional auger hoist, the utility model sets the spiral conveying structure 20 as at least one pair of tubular rotating shafts 200, and connects the pair of rotating shafts 200 through a fixed connector 202. During transportation, the rotating shaft 200 can be split, so that the relative length of the spiral conveying structure 20 is reduced, thereby facilitating transportation. During installation, one end of the insertion rod 207 can be inserted into the first fixed ring body 203 and one end of the rotating shaft 200 provided with the first fixed ring body 203, and then the first fixed blade 204 and the second fixed blade 206 are fixedly connected by at least one pair of fixing bolts 208, thereby facilitating the installation of the spiral conveying structure 20.

[0039] In order to further facilitate the installation of the spiral conveying structure 20 and the transportation of materials, a feed port 103 is provided at one end of the conveying pipeline 10 and a discharge port 104 is provided at the other end. The conveying pipeline 10 includes at least a pair of pipeline bodies 105, and the pipeline bodies 105 are connected by flanges.

During installation, the pipeline bodies 105 and the rotating shafts 200 can be installed in batches to facilitate the installation of the spiral conveying structure 20 .

[0041] The conveying pipeline 10 is configured as at least one pair of pipeline bodies 105, which can effectively reduce the relative length of the conveying pipeline 10 during transportation, thereby facilitating transportation. At the same time, during installation, the conveying pipeline 10 and the spiral conveying structure 20 can be installed one section at a time in coordination with the rotating shaft 200. By configuring the originally integrated conveying pipeline 10 and the spiral conveying structure 20 as a combination of multiple rotating shafts 200 and pipeline bodies 105, and by reducing the length of a single rotating shaft 200 and pipeline body 105, the difficulty of hoisting the integrated conveying pipeline 10 and the spiral conveying structure 20 can be effectively reduced, thereby reducing the difficulty of installing the overall structure.

[0042] The first fixing ring body 203 and the second fixing ring body 205 can be fixed on the rotating shaft 200 by welding.

[0043] like Figures 4 to 5 As shown, in order to facilitate enhancing the stability of transmission between two adjacent rotating shafts 200, this embodiment is modified on the basis of the above embodiment.

One end of the connecting shaft 102 passes through the connecting disk 101 and extends into the conveying pipeline 10. The connecting shaft 102 is rotatably connected to the connecting disk 101. The end of the connecting shaft 102 located in the conveying pipeline 10 is detachably connected to one end of the rotating shaft 200.

[0046] One end of the connecting shaft 102 can be inserted into the rotating shaft 200 and fixedly connected to the rotating shaft 200. The specific connection method can be a block-and-slot plug-in method. The block can be set on the connecting shaft 102, and the slot is set on the inner wall of the rotating shaft 200. The block and the slot are matched with each other, so that after one end of the connecting shaft 102 is inserted into the rotating shaft 200, the block is inserted into the slot to form a limit, so that the connecting shaft 102 and the rotating shaft 200 can rotate synchronously.

[0047] A shaft seal may be provided at the rotation connection between the connecting shaft 102 and the connecting disk 101 to facilitate sealing between the connecting shaft 102 and the connecting disk 101.

[0050] The transmission method between the driving wheel 301, the driven wheel 302 and the transmission belt 303 can adopt the pulley transmission method in the prior art that can realize the function of the utility model, for example: transmission is achieved through the friction between the transmission belt 303 and the driving wheel 301 and the driven wheel 302, or mating teeth are arranged on the driving wheel 301, the driven wheel 302 and the transmission belt 303 to mesh with each other, so that the transmission belt 303 and the driving wheel 301 and the driven wheel 302 are meshed and transmitted through mating teeth.

[0051] When in use, the driving motor 300 drives the driving wheel 301, which in turn drives the driven wheel 302 through the transmission belt 303, which in turn drives the connecting shaft 102 to rotate, and then drives the rotating shaft 200 connected to the connecting shaft 102 to rotate, thereby rotating the spiral conveying structure 20 to complete the lifting of the material.

[0052] In order to facilitate the installation of the conveying pipeline 10 and the driving motor 300, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that it also includes a mounting seat 40.
