[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0029] Example 1: A new type of spiral conveying auger, such as Figure 1 - Figure 6 As shown, it includes a screw dragon shaft 1, and the outer side of the screw dragon shaft 1 is equipped with a buffer blade segment 101, a transition blade segment 102, a feeding blade segment 103, a pressure reduction blade segment 104, and a blocking blade segment 105. The buffer blade segment 101, the transition blade segment 102, the feeding blade segment 103, the pressure reduction blade segment 104, and the blocking blade segment 105 have the same spiral diameter specifications, and the blocking blade segment 105 has an opposite spiral direction to the buffer blade segment 101, the transition blade segment 102, the feeding blade segment 103, and the pressure reduction blade segment 104. The blocking blade segment 105 is located at the end of the screw dragon shaft 1, the buffer blade segment 101 is located at the front end of the screw dragon shaft 1, the feeding blade segment 103 is located between the buffer blade segment 101 and the blocking blade segment 105, the transition blade segment 102 is located between the buffer blade segment 101 and the feeding blade segment 103, and the pressure reduction blade segment 104 is located between the feeding blade segment 103 and the blocking blade segment 105.

[0030] By setting the outer blades of the auger shaft 1 to have inconsistent specifications, it can have a variety of different effects under the same operation. First, based on the limitation of the pitch of the buffer blade segment 101 itself, under the initial limitation of the buffer blade segment 101 and the material, the material is reduced to reduce the material transfer volume and reduce the material flushing speed. Based on the transition blade segment 102, the material flowing through the buffer blade segment 101 continues to move and transmit, so that the material continues to move evenly. Based on the continuous transportation of the material by the feeding blade segment 103, the material flowing through the transition blade segment 102 continues to be evenly moved. Based on the blade of the pressure reduction blade segment 104 itself, the material is further moved. With the support of the distance between them, the flowing material moves a certain distance first and then is transmitted, which has the effect of relieving pressure. Based on the support of the reverse spiral of the blocking blade segment 105 itself, the circulating material is resisted and supported to prevent it from causing impact damage to the end of the auger shaft 1. Therefore, by combining the buffer blade segment 101, the transition blade segment 102, the feeding blade segment 103, the pressure reducing blade segment 104, and the blocking blade segment 105, the device is improved to have the functions of slowing down the impact of materials on the seal, evenly discharging materials into the hopper, releasing material pressure to reduce resistance, and blocking the impact of materials on the seal, thereby improving its efficiency and diversity.

[0031] like Figure 1- Figure 6 As shown, the auger shaft 1 is connected with the feed hopper 2, the auger barrel 3, and the discharge barrel 4. The auger shaft 1 extends out of the feed hopper 2 and the outside of the discharge barrel 4. A head end sealing block 6 is installed on the outside of the feed hopper 2, and an end sealing block 5 is installed on the outside of the discharge barrel 4. The end sealing block 5 and the head end sealing block 6 are used for the rotation seal of the auger shaft 1, and the auger shaft 1 extends the head end sealing block 6 to be connected to the outer drive device.

[0032] With the segmented support of the feed hopper 2, auger barrel 3, and discharge barrel 4, the auger shaft 1 and the fan blades at different positions thereon are ensured to be located within different processing steps, further improving the adaptability of the operating environment of each section of the auger shaft 1 and ensuring its stability and safety during actual use.

[0033] like Figure 1 - Figure 6 As shown, the buffer blade segment 101, the transition blade segment 102, and the feed blade segment 103 are all located inside the hopper 2. The pitch between two adjacent buffer blade segments 101 is smaller than the pitch between two adjacent transition blade segments 102, and the pitch between two adjacent feed blade segments 103 is slightly larger than the pitch between two adjacent transition blade segments 102.

[0034] The auger barrel 3 is located between the feed hopper 2 and the discharge barrel 4 , the pressure reducing blade segment 104 is located inside the auger barrel 3 near the feed hopper 2 , and the pitch between two adjacent pressure reducing blade segments 104 is greater than the pitch between two adjacent feeding blade segments 103 .

[0035] First, the pitch of the blades inside the buffer blade segment 101 is reduced as much as possible, which can be determined according to the characteristics of different material particle sizes, that is, the material conveying volume is reduced and the material flushing speed is reduced. Secondly, the blades here are extended out of the hopper 2 as much as possible under the condition of ensuring that no scratches occur, so as to block the material and prevent the material from directly impacting the head end sealing block 6, thereby reducing the wear of the head end sealing block 6 and the problem of powder leakage at the sealing point, extending the service life of the seal and the cleaning and maintenance cycle. Secondly, the transition blade segment 102 is designed into a transition pitch according to the hopper width, material conveying speed, and material ratio of each section, so as to achieve uniform material discharge in the hopper 2, improve the problem of piled material, and reduce the resistance of the accumulated material to the rotary conveying of the auger, thereby ensuring production, improving driving efficiency, and extending the life of the blades. Thirdly, the pitch of the pressure reducing blade segment 104 in the auger barrel 3 is appropriately increased, thereby reducing the blocking pressure, improving driving efficiency, and improving blade wear and service life.

[0036] Example 2: A new type of spiral conveying auger, such as Figure 1 - Figure 6 As shown, the blocking blade segment 105 is located inside the discharge barrel 4. The blocking blade segment 105 is composed of a single blade that can surround a circle, and the blades inside the blocking blade segment 105 are relatively strong.

[0037] Adjacent blades in the buffer blade segment 101 , the transition blade segment 102 , the feed blade segment 103 , and the pressure reduction blade segment 104 are fixedly connected to each other.

[0038] The blades in the blocking blade segment 105 are set as anti-spiral blades, and the specific pitch is based on the blade strength as the main reference item. It can block the direction of material rotation, block the impact of dust on the end seal, improve the sealing performance and seal life, and when the buffer blade segment 101, transition blade segment 102, feeding blade segment 103, and pressure reduction blade segment 104 are interconnected, the synchronization of the device during rotation can be improved, ensuring the stability and smoothness of material movement.

[0039] like Figure 1 - Figure 6 As shown, the feed hopper 2, the auger barrel 3, and the discharge barrel 4 are internally connected, and the upper part of the feed hopper 2 is connected to the external feed port, and the lower part of the discharge barrel 4 is connected to the external discharge port.

[0040] With the mutual connection between the feed hopper 2, the auger barrel 3, the discharge barrel 4 and the outer components, the device has a complete operating process, ensuring its safety and stability in actual use.

[0041] Working principle: When the material moves into the hopper 2, the auger shaft 1 is controlled to rotate at the same time, so that the material is buffered by the buffer blade segment 101, slowly guided by the transition blade segment 102, continuously transmitted by the feeding blade segment 103, first relieved and then guided by the pressure-reducing blade segment 104, and steadily moves into the discharge barrel 4. Finally, the anti-impact support of the blocking blade segment 105 allows the material to continue to move stably and safely.

[0042] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
