Description

Technical Field

[0001] This utility model relates to the field of material conveying equipment technology, and in particular to a material conveying joint structure. Background Technology

[0002] Grain conveyors are mainly used for loading and unloading bulk grain in grain warehouses and grain trucks. Based on different working principles and structural forms, grain conveyors can be divided into various types, the most common of which are belt conveyors, bucket elevators, screw conveyors and pneumatic conveyors.

[0003] Pneumatic conveyors utilize airflow (positive or negative pressure) to transport grain through pipelines. They are suitable for long-distance, complex-path transport and are widely used in grain processing, storage, and port loading and unloading. However, traditional pneumatic conveyors typically have fixed pipe bends that cannot be adjusted. When encountering different unloading heights and distances, multiple overall angle adjustments are required, which is time-consuming, labor-intensive, and affects loading and unloading efficiency, thus limiting their practical application.

[0035] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0036] like Figures 1 to 4 As shown, the material conveying joint structure of this utility model includes a joint assembly 100, which includes an infeed joint 1 and an outlet joint 2. The infeed joint 1 and the outlet joint 2 are coaxially aligned and face-to-face. A rotating mechanism 3 connects the infeed joint 1 and the outlet joint 2, allowing the infeed joint 1 and the outlet joint 2 to rotate relative to each other along a central axis. Airflow or material enters from the infeed joint 1 and exits from the outlet joint 2.

[0037] The main bodies of the feeding joint 1 and the discharging joint 2 are cylindrical, with the diameter of the feeding joint 1 equal to the diameter of the discharging joint 2. A feeding pipe 11 is provided on the feeding joint 1, and a first material chamber 101 is located inside the feeding joint 1; the feeding pipe 11 connects to the first material chamber 101. A discharging pipe 21 is provided on the discharging joint 2, and a second material chamber 201 is located inside the discharging joint 2; the discharging pipe 21 connects to the second material chamber 201. The feeding pipe 11 and the discharging pipe 21 are inserted into the feeding joint 1 and the discharging joint 2 in opposite tangential directions. For example, if the feeding pipe 11 is set in the positive tangential direction, then the discharging pipe 21 is set in the negative tangential direction, which facilitates angle adjustment and material feeding and discharging. The end faces of the feeding joint 1 and the discharging joint 2 away from each other are closed surfaces, while the end faces facing each other are provided with openings that connect the first material chamber 101 and the second material chamber 201. The openings of the feeding joint 1 and the discharging joint 2 are face-to-face connected. When the feeding joint 1 rotates relative to the discharging joint 2 to any working angle, the opening of the first material chamber 101 is connected to the opening of the second material chamber 201, ensuring that the first material chamber 101 is always connected to the second material chamber 201 at any working angle, thus ensuring that the material flow channel remains open at all times.

[0038] like Figure 5 , Figure 6As shown, the main body of the feeding joint 1 includes a coaxial first outer cylinder 12 and a first inner cylinder 13. The first outer cylinder 12 and the first inner cylinder 13 form an annular cylinder, and a first annular cavity 10 is formed between the first outer cylinder 12 and the first inner cylinder 13. The feeding pipe 11 is inserted into the first outer cylinder 12 tangentially, and its inner end extends into the first annular cavity 10 and communicates with the first annular cavity 10. The inner wall of the feeding pipe 11 is horizontally blocked in the first annular cavity 10. A first guide plate 16 is provided in the first annular cavity 10. The first guide plate 16 is a spiral plate or an inclined plate. The material is guided by the first guide plate 16, which facilitates the transition from the feeding joint 1 to the discharging joint 2. The first guide plate 16 and the transverse baffle wall of the feed pipe 11 divide the first annular cavity 10 into a first material cavity 101 and a first sealing cavity 102. The first material cavity 101 is the cavity between the first guide plate 16 and the transverse baffle wall of the feed pipe 11, and the remaining cavity is the first sealing cavity 102. The end faces of the first outer cylinder 12 and the first inner cylinder 13 away from the discharge joint 2 are covered with a first outer sealing plate 14, and the end face of the first sealing cavity 102 near the discharge joint 2 is covered with a first inner sealing plate 15. A first support plate 17 is placed radially transversely inside the first inner cylinder 13.

[0039] like Figure 7 , Figure 8 As shown, the main body of the discharge joint 2 includes a coaxial second outer cylinder 22 and a second inner cylinder 23. The second outer cylinder 22 and the second inner cylinder 23 form an annular cylinder, and a second annular cavity 20 is formed between the second outer cylinder 22 and the second inner cylinder 23. The diameter of the second outer cylinder 22 is equal to the diameter of the first outer cylinder 12, and the diameter of the second inner cylinder 23 is equal to the diameter of the first inner cylinder 13. The discharge pipe 21 is inserted tangentially into the second outer cylinder 22, and its inner end extends into the second annular cavity 20 and communicates with the second annular cavity 20. The inner wall of the discharge pipe 21 is horizontally blocked in the second annular cavity 20. A second guide plate 26 is provided in the second annular cavity 20. The second guide plate 26 is a spiral plate or an inclined plate. When the feeding joint 1 rotates to its maximum angle relative to the discharge joint 2, the second guide plate 26 cooperates with the first guide plate 16 to guide the material to the discharge pipe 21, which is more conducive to discharge. The second guide plate 26 and the transverse baffle wall of the discharge pipe 21 divide the second annular cavity 20 into a second material cavity 201 and a second sealing cavity 202. The second material cavity 201 is the cavity between the second guide plate 26 and the transverse baffle wall of the discharge pipe 21, and the remaining cavity is the second sealing cavity 202. The length (arc length) of the second material cavity 201 is greater than the length (arc length) of the first material cavity 101. The end faces of the second outer cylinder 22 and the second inner cylinder 23 away from the feed joint 1 are covered with a second outer sealing plate 24, and the end face of the second sealing cavity 202 near the feed joint 1 is covered with a second inner sealing plate 25. A second support plate 27 is placed radially transversely inside the second inner cylinder 23.

[0040] like Figure 3 , Figure 4 As shown, in this embodiment, the rotating mechanism 3 uses a rotating bearing 31 and a driving mechanism 32 to drive the relative rotation of the feeding joint 1 and the discharging joint 2. The rotating mechanism 3 is connected to the first support plate 17 of the feeding joint 1 and the second support plate 27 of the discharging joint 2.

[0041] like Figure 9 As shown, in other embodiments, the rotating mechanism 3 can also use a main shaft 33, bearings 34 and a drive mechanism 32 to drive the relative rotation of the feeding joint 1 and the discharging joint 2. The main shaft 33 is axially mounted on the feeding joint 1 and the discharging joint 2. Bearings 34 are respectively sleeved between the main shaft 33 and the feeding joint 1 and the discharging joint 2. The main shaft 33 is connected to the drive mechanism 32 (the drive mechanism 32 is not shown in the figure).

[0042] The feeding joint 1 and the discharging joint 2 can be configured such that one is a fixed part and the other is a rotatable part, and the rotatable part is driven to rotate by the rotating mechanism 3 to adjust the angle; or both the feeding joint 1 and the discharging joint 2 can be configured as rotatable parts, and the rotatable part is driven to rotate by the rotating mechanism 3 to adjust the angle.

[0043] like Figures 10 to 12 As shown, in actual use, the feed pipe 11 of the joint assembly 100 is connected to the suction pipe 4, and the discharge pipe 21 is connected to the hopper 6 via the conveying pipe 5. Activating the air source equipment creates negative pressure in the pipeline. Under this negative pressure, the material is sequentially conveyed to the hopper 6 via the suction pipe 4, the joint assembly 100, and the conveying pipe 5. Depending on actual needs, rotating the feed joint 1 and / or the discharge joint 2 can adjust the angle of the feed pipe 11 and / or the discharge pipe 21. Figure 10 The first operating angle is shown, in which both the feed pipe 11 and the discharge pipe 21 are at a horizontal angle; Figure 11 The second usage angle is shown, in which the feed pipe 11 is tilted downwards and the discharge pipe 21 is at a horizontal angle; Figure 12 The third operating angle is shown, in which the feed pipe 11 is at a vertical angle and the discharge pipe 21 is at a horizontal angle.

[0044] The joint assembly 100 of this utility model adopts two cylindrical joints facing each other, and the feed pipe 11 and the discharge pipe 21 are inserted tangentially into the corresponding joints. The two joints can rotate relative to each other around the same axis. By rotating the joints, the relative angle between the feed pipe 11 and the discharge pipe 21 can be adjusted to adapt to different loading and unloading heights, loading and unloading distances and other requirements. It has strong adaptability, is simple, convenient and reliable to operate, and improves loading and unloading efficiency.

[0045] The above description is an explanation of this utility model and not a limitation thereof. This utility model can be modified in any form without departing from its spirit. For example, "feeding" and "discharging" are only relative definitions.
