Description

Technical Field

[0001] This utility model relates to the field of cement conveying chute technology, specifically a steerable cement conveying chute. Background Technology

[0002] Cement conveying chute is a pneumatic conveying device that uses airflow to fluidize materials and transport dry powdery materials along the chute. It features low energy consumption and easy maintenance and is widely used in the cement industry.

[0003] In the existing cement industry, cement shipments are large, so cement elevators need to operate for a long time. Each component of the elevator has its own service life. When the key components of the elevator are damaged, the elevator will stop and affect the cement's delivery.

[0004] To overcome the above-mentioned defects, the prior art (Chinese patent No. CN216548548U, published on 2022-05-17) discloses a cement conveying chute interconnection device, including an air-filled box A, an air-filled box B, an air-filled box C, a connecting pipe one, and a connecting pipe two. The air-filled box B is connected to the first air-filled chute conveyor, and the air-filled box A and the air-filled box C are connected to the second air-filled chute conveyor. The first connecting pipe connects the air-filled box A and the air-filled box B, and the second connecting pipe connects the air-filled box B and the air-filled box C. The first connecting pipe and the second connecting pipe are respectively equipped with valve A and valve C. Valve B is provided on the second air-filled chute conveyor section between the air-filled box A and the air-filled box C. Valve D is provided on the first air-filled chute conveyor section after the air-filled box B. The beneficial effect is that even if the elevator on one conveyor fails, materials can still be smoothly discharged from that conveyor.

[0005] While the above design can solve the aforementioned problems, cement will accumulate and solidify at the connection end during long-term cement transportation, which will hinder the overall operation and adjustment functions of the equipment. At the same time, the existing designs mostly rely on manual direct pushing to control the cement flow direction, which makes the use of the equipment very time-consuming and labor-intensive, reducing the efficiency and convenience of the equipment.

[0006] The purpose of this utility model is to provide a steerable cement conveying chute to solve the problem mentioned in the background art where cement accumulates and solidifies at the connection end during long-term cement conveying, which hinders the overall operation and adjustment functions of the equipment. At the same time, existing designs mostly use manual direct pushing to control the flow direction of cement, which makes the use of the equipment very time-consuming and labor-intensive, reducing the efficiency and convenience of the equipment.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a steerable cement conveying chute, comprising a cement conveying trough, wherein a swing adjustment trough is installed on the outer surface of the cement conveying trough, and a fitting cleaning mechanism for moving an internal cleaning frame back and forth is installed inside the swing adjustment trough, the fitting cleaning mechanism comprising a rotary drive motor, and the rotary drive motor is fixedly installed on the side of the swing adjustment trough; a rotating support frame is installed on the upper surface of the cement conveying trough, and a rotating adjustment mechanism for rotating the swing adjustment trough as a whole is installed inside the rotating support frame.

[0008] Furthermore, the rotation adjustment mechanism includes an integral fixed plate, which is nested inside the rotation support frame. An insertion connecting plate is installed at the front end of the integral fixed plate, and a sliding nested rod is installed inside the insertion connecting plate.

[0009] Furthermore, the front end of the swing adjustment groove is rotatably mounted on the upper and lower sides of the cement conveying groove, and a central extension rod is installed at the center of the swing adjustment groove. The front end of the sliding nested rod is nested on the outer surface of the central extension rod, and the sliding nested rod is slidably mounted inside the insertion connecting plate.

[0010] Furthermore, a push-meshing rack is installed on the outer surface of the output end of the rotary drive motor, and the integrated gear rod is rotatably installed on the upper surface of the swing adjustment groove. A central fixing rod is installed on the outer surface of the other end of the integrated gear rod, and an insertion transmission rod is installed at the end of the central fixing rod.

[0011] Furthermore, the side of the swing adjustment groove is provided with a transverse limiting inner groove, and the side of the inner cleaning rack is nested inside the transverse limiting inner groove. The inner surface of the insertion transmission rod is slidably installed inside the side of the inner cleaning rack, and the inner surface of the inner cleaning rack is fitted to the outer surface of the swing adjustment groove.

[0012] Furthermore, the outer surface of the pushing meshing rack contacts the outer surface of the gear integrated rod to form a meshing structure, and the side of the inserted transmission rod is slidably installed inside the side of the internal cleaning frame, and the inner surface of the transverse limiting inner groove contacts the side of the internal cleaning frame to form a sliding structure.

Moreover, the swing adjustment groove is externally limited and rotated along the opening of the cement conveying trough.

[0014] Compared with the prior art, the beneficial effects of this utility model are: when the inside of the swing adjustment trough of the steerable cement conveying chute needs to be cleaned, the rotary drive motor is directly started to drive the gear rod to rotate by pushing the meshing rack. At this time, the central fixed rod can drive the internal cleaning frame by inserting the transmission rod. This design prevents cement from accumulating and solidifying, which makes the overall operation and adjustment function of the equipment smoother. Furthermore, when it is necessary to adjust the swing adjustment channel, simply rotate the integrated fixed plate to drive the sliding nested rod by inserting the connecting plate. At this time, the central extension rod can drive the swing adjustment channel along the output end of the cement conveying channel. This design makes the equipment more efficient and convenient to use. Furthermore, the swing adjustment groove and the central extension rod are designed as a single unit, so that the central extension rod can drive the swing adjustment groove in a corresponding manner through the sliding nested rod. This design makes the equipment more stable to use. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: Please refer to Figure 2 , Figure 3 and Figure 4 This utility model provides the following technical solution: a steerable cement conveying chute, including a cement conveying trough 1, a swing adjustment trough 2 installed on the outer surface of the cement conveying trough 1, and a fitting cleaning mechanism for moving an internal cleaning frame 13 back and forth inside the swing adjustment trough 2, such as... Figure 3 As shown, the bonding cleaning mechanism includes a rotary drive motor 8, which is fixedly installed on the side of the swing adjustment trough 2. A rotating support frame 6 is installed on the upper surface of the cement conveying trough 1, and a rotation adjustment mechanism for rotating the swing adjustment trough 2 as a whole is installed inside the rotating support frame 6.

[0019] like Figure 2 , Figure 3 and Figure 4 The technical solution shown addresses the problem of cement accumulation and solidification at the connection end during long-term cement conveying, which hinders the overall operation and adjustment functions of the equipment. It discloses a rotating adjustment mechanism comprising an integrated fixed disk 7 nested within a rotating support frame 6. An insertion connecting disk 5 is mounted at the front end of the integrated fixed disk 7, and a sliding nested rod 4 is installed inside the insertion connecting disk 5. The swing adjustment groove 2 is rotatably mounted on the upper and lower sides of the cement conveying trough 1 at its front end, and a central extension rod 3 is installed at the center of the swing adjustment groove 2. Figure 4 As shown, the front end of the sliding nested rod 4 is nested on the outer surface of the central extension rod 3, and the sliding nested rod 4 is slidably installed inside the insertion connecting plate 5. The insertion connecting plate 5 and the integral fixed plate 7 are designed as a whole, and the outer surface of the central extension rod 3 and the inner surface of the sliding nested rod 4 are in contact to form a sliding structure. Moreover, the swing adjustment groove 2 is externally limited and rotated along the opening of the cement conveying groove 1.

[0020] After prolonged cement conveying operations, when cleaning the cement adhering to the inner surface of the swing adjustment trough 2, the rotary drive motor 8, fixedly mounted on the side of the swing adjustment trough 2, is directly started to perform reciprocating push-pull operation. During the operation of the rotary drive motor 8, the push meshing rack 9, fixedly mounted on the outer surface of the front output end, is synchronously pulled back and forth. During the movement of the push meshing rack 9, it comes into contact with the externally abutting gear rod 10 and generates a meshing motion. Since the gear rod 10 is rotatably mounted on the upper surface of the swing adjustment trough 2, the swing adjustment trough 2 can generate synchronous and stable circumferential rotation driven by the meshing motion. Figure 4As shown, the operation of the gear-integrated rod 10 will synchronously drive the middle fixing rod 11, which is fixedly installed inside the other end, to rotate. At this time, the movement of the middle fixing rod 11 will synchronously pull the insertion transmission rod 14, which is nested on the other end. Since the insertion transmission rod 14 is slidably installed on the corresponding side of the inner cleaning rack 13, the insertion transmission rod 14 will always remain vertical. The inner cleaning rack 13 can then move laterally with the drive of the insertion transmission rod 14. During the movement of the inner cleaning rack 13, it will conform to the inner side of the lateral limiting groove 12 opened at the corresponding position on the side of the swing adjustment groove 2. The inner side of the swing adjustment groove 2 and the outer side of the inner cleaning rack 13 are in contact with each other, so that the cement adhering inside the swing adjustment groove 2 can be cleaned efficiently.

[0021] Example 2: Figure 1 , Figure 5 and Figure 6 The technical solution shown addresses the problem that existing designs for controlling cement flow mostly rely on manual pushing, which makes equipment use time-consuming and labor-intensive, reducing efficiency and convenience. The solution discloses: a push-meshing rack 9 is mounted on the outer surface of the output end of the rotary drive motor 8; a gear-integrated rod 10 is rotatably mounted on the upper surface of the swing adjustment groove 2; a central fixing rod 11 is mounted on the outer surface of the other end of the gear-integrated rod 10; an insertion transmission rod 14 is mounted at the end of the central fixing rod 11; a transverse limiting inner groove 12 is formed on the side of the swing adjustment groove 2; the side of the internal cleaning frame 13 is nested inside the transverse limiting inner groove 12; and the inner surface of the insertion transmission rod 14 is slidably mounted inside the side of the internal cleaning frame 13. Figure 5 As shown, the inner surface of the internal cleaning rack 13 and the outer surface of the swing adjustment groove 2 are fitted together, the outer surface of the push meshing rack 9 and the outer surface of the gear rod 10 are in contact to form a meshing structure, and the side of the insertion transmission rod 14 is slidably installed inside the side of the internal cleaning rack 13, and the inner surface of the transverse limiting inner groove 12 is in contact with the side of the internal cleaning rack 13 to form a sliding structure.

[0022] When the output end of the swing adjustment groove 2 needs to be adjusted according to actual use, the integrated fixing plate 7 is directly fixed, and the integrated fixing plate 7 is limited to rotate inside the rotating support frame 6 fixed at the corresponding position on the top of the cement conveying trough 1. At this time, the integrated fixing plate 7 can drive the front-end integrated insertion connecting plate 5 to rotate synchronously. During the movement of the insertion connecting plate 5, the sliding nested rod 4 inside will be driven synchronously. Figure 6As shown, at this time, the other end of the sliding nested rod 4 will fit against the outside of the circular extension rod 3 and move up and down. Since the circular extension rod 3 is fixedly installed at the center of the swing adjustment groove 2, the swing adjustment groove 2 can rotate left and right under the drive of the sliding nested rod 4. During the driving process, the sliding nested rod 4 will also slide back and forth along the inside of the insertion connecting plate 5. This design makes the use of the equipment more convenient and efficient, and makes the adjustment work more time-saving and labor-saving.
