[0021] like Figure 1 As shown, this utility model is an airtight feeding tube, including a fixed feeding tube 1, a rotating feeding tube 3 rotatably connected to the bottom of the fixed feeding tube 1 via a slewing bearing 2, a bracket 4 mounted on the outer wall of the rotating feeding tube 3, an airtight mechanism 7 provided around the rotating feeding tube 3, and a swing feeding tube 8 hinged to the bottom of the rotating feeding tube 3. The rotating feeding tube 3, the bracket 4, and the swing feeding tube 8 are provided with a swing feeding tube adjustment mechanism.
[0022] like Figure 2 The airtight mechanism 7 consists of a vertical cover 11, a sealing ring 12, and a vertical dustproof and waterproof plate 13. The vertical cover 11 is welded or bolted to the outer wall of the rotating feed pipe 3. A mounting step is located at the bottom inner side of the cover for vertically fixing the sealing ring 12. The outer circle of the sealing ring 12 contacts the vertical inner wall of the vertical cover 11, and the inner circle of the sealing ring 12 contacts the outer wall of the vertical dustproof and waterproof plate 13. The sealing ring 12 is an inflatable sealing ring; after inflation, it expands to seal the vertical cover 11 and the vertical dustproof and waterproof plate 13, thus providing a seal.
[0023] The swing feeding tube adjustment mechanism includes a swing control winch 5 and a rope wheel bracket. The swing control winch 5 is mounted on the bracket 4. The two rope wheel brackets are arranged vertically on the outside of the rotating feeding tube 3. Swing steering wheels are mounted on the rope wheel brackets. The swing control winch 5 is connected to one end of the swing adjustment rope 19. The other end of the swing adjustment rope 19 passes around the two swing steering wheels and is connected to the lifting lug on the outer wall of the swing feeding tube 8.
[0024] The swing adjustment rope 19 is made of steel wire rope.
[0025] The feed tube 1 is either round or square.
[0026] In order to extend the service life of the oscillating feed tube 8, a wear-resistant tube is installed inside the oscillating feed tube 8. The wear-resistant tube is made of steel pipe.
[0027] To prevent the oscillating feed tube 8 from impacting the rotating feed tube 3 during oscillation, a crash barrier 10 is installed on the lower outer wall of the rotating feed tube 3. Specifically, the crash barrier 10 is made of polyurethane material.
[0028] To expand the range of material feeding, a telescopic tube 9 is slidably sleeved around the outer periphery of the oscillating feeding tube 8. Specifically, a combination roller 14 is fixed to the inner wall of the telescopic tube 9, and a C-shaped guide rail 15 is fixed to the outer wall of the oscillating feeding tube 8. The combination roller 14 is embedded in the C-shaped guide rail 15 and slides within the guide rail.
[0029] A limiting structure is provided between the swing feeding tube 8 and the telescopic tube 9. The limiting structure includes a first fixed limiting block 16, a second fixed limiting block 17, and a sliding limiting block 18. The first fixed limiting block 16 and the second fixed limiting block 17 are located at both ends of the outer wall of the swing feeding tube 8, and the sliding limiting block 18 is fixed to the inner wall of the telescopic tube 9. The sliding limiting block 18 slides between the first fixed limiting block 16 and the second fixed limiting block 17.
[0030] In order to extend the service life of the telescopic tube 9, a wear-resistant tube is installed inside the telescopic tube 9. The wear-resistant tube is made of steel pipe.
[0031] Meanwhile, to better control the telescopic pipe 9, a telescopic pipe adjustment mechanism is provided on the rotating feed pipe 3, the support 4, and the telescopic pipe 9. The telescopic pipe adjustment mechanism includes a telescopic control winch 6 and a telescopic steering wheel. The telescopic control winch 6 is mounted on the support 4, and the telescopic steering wheel is mounted on the rope wheel support. The telescopic control winch 6 is connected to one end of the telescopic adjustment rope 20, and the other end of the telescopic adjustment rope 20 passes around the two telescopic steering wheels and is connected to the lifting lug on the outer wall of the telescopic pipe 9.
[0032] The telescopic adjustment rope 20 is made of steel wire rope.
[0033] An airtight material feeding pipe installation structure includes an airtight material feeding pipe installed on a silo. The top of the silo is a silo top 21, and a silo inlet 22 is opened on the silo top 21. The top of a fixed feeding pipe 1 is connected to an incoming material pipe 23. The upper part of a rotating feeding pipe 3 is located in the silo inlet 22. A bracket 4 is located above the silo inlet 22. The lower part of the rotating feeding pipe 3, the swing feeding pipe 8, and the telescopic pipe 9 extend into the silo. A vertical waterproof and dustproof plate 13 is connected to the silo inlet 22. The sealing ring 12 expands after being inflated, sealing the passage between the inside of the silo and the outside, thus achieving a sealing function.
[0034] The working process of this utility model is as follows:
[0035] After the material arrives from the upstream feed pipe 23, it enters the fixed feed pipe 1, then flows down into the rotating feed pipe 3, then into the swing feed pipe 8, and finally flows into the material bin through the telescopic pipe 9. The impact force of the material falling from the top of the bin impacts the arching point, thus achieving the arch-breaking effect.
[0036] To adjust the impact point, the bracket 4 can be manually pushed to adjust the plane angle of the rotating feed tube 3; the telescopic control winch 6 can be cranked to extend or shorten the swing adjustment rope 19 to control the vertical angle of the swing feed tube; the telescopic control winch 6 can also be cranked to extend or shorten the telescopic adjustment rope 20 to control the extension or retraction of the telescopic tube 9 along the axis of the swing feed tube 8. These three actions combined can adjust the position of the material's impact point in the plane projection direction.
[0037] This utility model's airtight flushing pipe is equipped with an airtight device, which can effectively reduce fumigation loss and leakage of toxic substances during the circulating fumigation stage in the silo. The flushing pipe can rotate freely 360° and is equipped with a telescopic joint, which can freely adjust the flushing angle and range.
[0038] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
