[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0034] like Figures 1 to 11 As shown, the utility model provides an auger conveyor, including an auger shaft 1, a first fixed flange 2 and a second fixed flange 3 arranged at both ends of the auger shaft 1, a first sealing assembly 4 arranged on the first fixed flange 2, a second sealing assembly 5 arranged on the second fixed flange 3, a first bearing assembly 6 arranged at the end of the first sealing assembly 4 away from the first fixed flange 2, and a second bearing assembly 7 arranged at the second sealing assembly 5 away from the second fixed flange 3, the first sealing assembly 4 and the second sealing assembly 5 both include a sealing sleeve 41, a first wool felt sealing ring 42 and a second wool felt sealing ring 43 arranged in the sealing sleeve 41 and sleeved on the outside of the auger shaft 1, an oiling sleeve 44 is arranged between the first wool felt sealing ring 42 and the second wool felt sealing ring 43, and a sealing gasket pressing plate 8 is provided on the second wool felt sealing ring 43. The utility model realizes double sealing by arranging the first wool felt sealing ring 42 and the second wool felt sealing ring 43. The oiling spacer 44 is added with edible oil to play a good lubricating role, thereby avoiding heat generation by friction and extending the service life of the first wool felt sealing ring 42 and the second wool felt sealing ring 43. The sealing pad pressing plate 8 is used to extrude the second wool felt sealing ring 43. In this way, even if the wool felt sealing ring is worn, it can still play a good sealing role under the action of extrusion, thereby preventing powder leakage and avoiding waste of powder.

[0035] The sealing sleeve 41 is fixed to the first fixing flange 2 or the second fixing flange 3 by a first fastener 9 (specifically a hexagon socket head screw in this embodiment).

[0036] The sealing gasket pressing plate 8 is fixed on the sealing sleeve 41 .

[0037] The first bearing assembly 6 is configured as a seat bearing, and the seat bearing is sleeved on the auger shaft 1. The sealing sleeve 41 is fixedly connected to the seat body of the first bearing assembly 6.

[0038] From outside to inside, the second bearing assembly 7 includes a bearing seat 71 , a universal bearing 72 and a bearing sleeve 73 . The bearing sleeve 73 is sleeved on the auger shaft 1 .

[0039] The bearing seat 71 is fixed to the sealing sleeve 41 by a third fastener 11 (specifically a hexagon socket screw in this embodiment).

[0040] The bearing sleeve 73 is secured to the auger shaft 1 via a fourth fastener 12 (specifically, a set screw in this embodiment). The ingenious design of the second bearing assembly 7, employing a universal joint 72 with a movable inner ring and a stationary outer ring, ensures concentricity during shaft rotation, preventing shaft breakage, significantly extending the conveyor's service life, and reducing consumable material waste.

[0041] The sealing sleeve 41 comprises a circular ring block 411 and four screw posts 412 evenly distributed around the circumference of the upper surface of the ring block 411. A first wool felt sealing ring 42 and a second wool felt sealing ring 43 are both mounted on the inner wall of the ring block 411. The ring block 411 is provided with a screw 413 and a screw hole 414. The screw posts 412 are formed with screw holes 415. The sealing sleeve 41 and the first bearing assembly 6 are connected via screws disposed in the screw holes 415. The first fastener 9 passes through the screw holes 414 and is embedded in the first fixing flange 2 or the second fixing flange 3.

[0042] The sealing gasket pressure plate 8 includes a pressure plate body 81 and connecting blocks 82 extending outward from the four sides of the pressure plate body 81 (four L-shaped structures are formed on the sealing gasket pressure plate 8). During assembly, the connecting block 82 is located on one side of the screw column 412 (the screw column 412 is provided at the corner of the L-shaped structure). The outer edge of the connecting block 82 is arc-shaped, matching the shape of the annular block 411. A connecting hole 821 is provided on the connecting block 82, and the screw 413 is inserted into the connecting hole 821 and then locked by a nut to achieve a fixed connection between the sealing sleeve 41 and the sealing gasket pressure plate 8. By adjusting the nut on the screw and moving downward, the wool felt is squeezed to deform the wool felt and fit tightly against the shaft, thereby achieving a sealing effect.

[0043] A through hole 811 and a protrusion 812 extending downward from the plate body 81 are formed in the central region of the plate body 81. An L-shaped step 813 is formed between the outer side of the protrusion 812 and the plate body 81. The inner side of the protrusion 812 forms a portion of the through hole 811. The protrusion 812 precisely presses against the second wool felt sealing ring 43, stretching it and achieving a better sealing effect.

[0044] In short, the utility model can achieve good sealing and prevent powder waste through ingenious structural design. Moreover, by using universal bearings, the concentricity of the machine shaft can be guaranteed, solving the problem of broken shaft in the prior art, greatly extending the service life of the conveyor and reducing the waste of consumables.
