Background

The auger is commonly known as a screw conveyor, and the rotating helical blade pushes materials to convey the materials, so that the screw conveyor is widely applied to various industries and is suitable for horizontal conveying, inclined conveying, vertical conveying and other forms of granular or powdery materials. The rotating blade needs to be fixedly connected with a shaft rod extending out of the casing, the shaft rod needs to be driven by the motor to rotate so as to drive the auger to run, and therefore a bearing is usually arranged between the shaft rod and the casing to be connected. At present, the bearings of most packing augers in the market are directly installed on a machine shell, so that powder materials can be in direct contact with the bearings, especially for the powder materials less than 150 microns, the powder can directly enter the bearings during daily operation, the bearings are blocked or damaged, and the damage rate is high.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a novel auger to the above-mentioned problem that prior art exists, the utility model aims to solve the technical problem that through optimizing the structure of auger, make the powder material and the bearing in it keep apart to avoid the powder material to get into in the bearing and make the bearing damage, prolong its life.

The purpose of the utility model can be realized by the following technical proposal: the novel auger is characterized by comprising a barrel, an end plate and a rotating blade, wherein the end plate and the barrel are fixedly connected together to form an auger bin; the packing pressing seat is cylindrical, and one end of the packing pressing seat is fixedly connected with the end plate; a first through hole is formed in the packing pressing seat on the end plate, the inner diameter of the first through hole is smaller than that of the packing pressing seat, a shaft lever is arranged on the rotating blade along the axis direction of the rotating blade, the shaft lever sequentially penetrates through the first through hole and the packing pressing seat, and a packing and a pressing sleeve are sequentially arranged in the packing pressing seat and on the shaft lever from one end, close to the end plate, of the packing pressing seat to the other end of the packing pressing seat in an extending mode; the packing auger also comprises a gland, wherein a second through hole is formed in the gland, the inner diameter of the second through hole is smaller than the outer diameter of the pressing sleeve, the gland is sleeved on the shaft rod, one end of the gland is connected with the packing pressing seat through threads, and a bearing is arranged at the other end of the gland; the bearing is sleeved on the shaft lever, the inner ring of the bearing is fixedly connected with the shaft lever, and the outer ring of the bearing is fixedly connected with the gland.

The outer end of the gland can be provided with a bearing mounting groove, and the bearing can be directly clamped in the bearing mounting groove, so that the subsequent replacement of the bearing is facilitated. When the packing auger is assembled, an end plate, a pressing sleeve and an assembled gland with a bearing can be sleeved on the shaft lever in sequence; then packing the packing in the packing pressing seat, and then arranging the pressing sleeve in the packing pressing seat; then, the gland is installed on the packing pressing seat and is tightly screwed (at the moment, because the inner diameter of the first through hole is smaller than that of the packing pressing seat, and only a small gap is formed between the shaft rod and the end plate, a notch is formed in the shaft rod when the shaft rod is inserted into the packing pressing seat, and the packing can be placed in the notch, so that the packing can be continuously extruded in the process of tightly covering the gland, and the gap between the shaft rod and the end plate can be sealed); finally, the rotating blades and the like are inserted into the cylinder body and fixed, and one end of the packing auger is assembled. The packing seal structure is adopted by the packing auger to isolate the auger bin from the bearing, so that powder materials in the auger bin can not enter the bearing, the blocking and damage of the bearing are effectively avoided, and the service life of the auger is prolonged.

The utility model discloses the advantage:

in this auger, bearing life has promoted by a wide margin than before, saves the cost simultaneously, and is effectual, has improved the stability of equipment.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1, 2 and 3, the novel packing auger comprises a barrel body 1, an end plate 2 and a rotating blade 3, wherein the end plate 2 and the barrel body 1 are fixedly connected together to form a packing auger bin 4, the rotating blade 3 is arranged in the packing auger bin 4, and a packing pressing seat 5 is arranged at the middle position of the end plate 2, which is positioned outside the packing auger bin 4; the packing pressing base 5 is cylindrical, and one end of the packing pressing base 5 is fixedly connected with the end plate 2; a first through hole 21 is formed in the packing pressing base 5 on the end plate 2, the inner diameter of the first through hole 21 is smaller than that of the packing pressing base 5, a shaft lever 6 is arranged on the rotating blade 3 along the axial direction of the rotating blade 3, the shaft lever 6 sequentially penetrates through the first through hole 21 and the packing pressing base 5, and a packing 7 and a pressing sleeve 8 are sequentially arranged in the packing pressing base 5 and on the shaft lever 6 in a manner that the packing pressing base 5 extends from one end close to the end plate 2 to the other end; the packing auger also comprises a gland 9, a second through hole 91 is formed in the gland 9, the inner diameter of the second through hole 91 is smaller than the outer diameter of the pressing sleeve 8, the gland 9 is sleeved on the shaft rod 6, one end of the gland 9 is connected with the packing pressing seat 5 through threads, and a bearing 92 is arranged at the other end of the gland 9; the bearing 92 is sleeved on the shaft lever 6, an inner ring of the bearing 92 is fixedly connected with the shaft lever 6, and an outer ring of the bearing 92 is fixedly connected with the gland 9.
