When discharging, the receiving pipe is connected to the discharge pipe, and the cement raw materials can be smoothly transferred to the transport vehicle. However, during the discharge process, the connection between the receiving pipe and the discharge pipe is easily broken, which leads to the cessation of discharge and a large amount of waste of cement raw materials, affecting the continuity and efficiency of cement raw material discharge. Utility Model Content
[0003] The purpose of this utility model is to provide a fixing structure for the connection of the feeding pipe, which can solve the technical problem that the connection between the feeding pipe and the receiving pipe is prone to breakage, affecting the continuity of feeding. It tightens and fixes the connection between the feeding pipe and the receiving pipe to prevent the connection from loosening and breaking, thus ensuring the continuity of feeding.
[0004] To achieve the above objectives, this utility model employs the following technical solution:
[0005] A fixing structure for a discharge pipe connection includes a first locking clamp and a pull rod disposed between a discharge pipe and a receiving pipe. The receiving pipe is sleeved on the outside of the discharge pipe, and the first locking clamp is sleeved on the outside of the receiving pipe. The first locking clamp includes two symmetrically arranged left and right clamps, one end of the left clamp and one end of the right clamp are rotatably connected, and a locking rod is provided between the other ends of the left and right clamps. One end of the pull rod is rotatably connected to the discharge pipe, and the other end of the pull rod is provided with a second locking clamp, which is sleeved on the outside of the receiving pipe.
[0006] Furthermore, one end of the locking rod is rotatably connected to the right hoop, and the left hoop is provided with a retaining ring for use with the locking rod.
[0007] Furthermore, the retaining ring is provided with a notch for use with a locking rod. The locking rod passes through the notch and enters the interior of the retaining ring.

[0020] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0021] Reference Figure 1 and Figure 2 This utility model describes a fixing structure for the connection of a discharge pipe. The main structure includes a first locking clamp 3 and a pull rod 4 disposed between the discharge pipe 1 and the receiving pipe 2. The discharge pipe 1 is connected to a storage tank, and the receiving pipe 2 is connected to a transport vehicle. The receiving pipe 2 is sleeved on the outside of the discharge pipe 1. The receiving pipe 2 is generally made of a flexible material such as rubber, while the discharge pipe 1 is made of a rigid material such as metal or plastic, allowing the receiving pipe 2 to be bent or compressed to fit against the outside of the discharge pipe 1. The first locking clamp 3 is sleeved on the outside of the receiving pipe 2. A locking clamp 3 is located on the outside of the connection between the receiving pipe 2 and the discharging pipe 1, tightening the connection to increase friction and reduce the likelihood of loosening or breaking. The first locking clamp 3 includes two symmetrically arranged left clamp rings 5 and right clamp rings 6. One end of the left clamp ring 5 and one end of the right clamp ring 6 are rotatably connected by a pin or hinge. A locking rod 7 is provided between the other ends of the left clamp ring 5 and the right clamp ring 6. After the first locking clamp 3, composed of the left clamp ring 5 and the right clamp ring 6, is opened by rotation, it is fitted onto the receiving pipe. The outside of 2 is rotated, and then the two are closed by rotating in the opposite direction. The locking rod 7 between the ends of the two is used to lock and fix them, so that the two are more firmly fitted at the connection. The structure is simple and easy to operate. It can lock and reinforce the connection between the two, and improve the firmness of the connection. One end of the pull rod 4 is rotatably connected to the feed pipe 1. Specifically, a fixed shaft is set on the feed pipe 1, and the end of the pull rod 4 is rotatably connected to the fixed shaft. The other end of the pull rod 4 is fixed with a second locking clamp 8 by welding or bolting. The material receiving pipe 2 is sleeved on the outside of the material discharging pipe 1. After the material receiving pipe 2 is sleeved on the outside of the material discharging pipe 1, the pull rod 4 is rotated so that the second locking clamp 8 at the other end of the pull rod is rotated close to the material receiving pipe 2. Then the second locking clamp 8 is sleeved on the outside of the material receiving pipe 2, thereby tightening and fixing the material receiving pipe 2 and the material discharging pipe 1 in the axial direction. This prevents the two from loosening or breaking in the axial direction, greatly improves the firmness of the connection, avoids the material discharging stoppage or material waste caused by the connection breaking during the material discharging process, and ensures the continuity and efficiency of material discharging.
[0022] Preferably, one end of the locking rod 7 is rotatably connected to the right hoop 6 via a pin or hinge, and the left hoop 5 is provided with a retaining ring 9 that cooperates with the locking rod 7. With this structure, after the left hoop 5 and the right hoop 6 are closed, the locking rod 7 is rotated to cooperate with the retaining ring 9 on the left hoop 5, thereby locking and fixing the movable ends of the left hoop 5 and the right hoop 6. The structure is simple and easy to operate, improving the firmness and convenience of locking the movable ends of the left hoop 5 and the right hoop 6.
[0023] Preferred, refer to Figure 3 The retaining ring 9 is provided with a notch 10 for use with the locking rod 7. The notch 10 penetrates the side wall of the retaining ring 9. The locking rod 7 passes through the notch 10 and enters the interior of the retaining ring 9. A sleeve 11 is threadedly connected to the locking rod 7. One end of the sleeve 11 is fixed with a stop block 12 that contacts the side of the retaining ring 9 by welding or integral molding. With this structure, rotating the sleeve 11 will drive the stop block 12 at its end to move toward the retaining ring 9. After the stop block 12 contacts the side of the retaining ring 9, continue to rotate the sleeve 11 to further tighten and fix the movable ends of the left hoop 5 and the right hoop 6. The threaded connection structure keeps the stop block 12 in contact with the retaining ring 9, which can further lock and fix the connection state of the left hoop 5 and the right hoop 6 after they are combined. This greatly improves the locking force at the connection, increases the relative friction at the connection, and ensures the firmness of the connection.
[0024] Preferred, refer to Figure 4 The second locking clamp 8 includes an upper clamp ring 13 and a lower clamp ring 14. One end of the upper clamp ring 13 and one end of the lower clamp ring 14 are rotatably connected by a pin or hinge. The other end of the upper clamp ring 13 and the other end of the lower clamp ring 14 are movably connected. This structure allows the second locking clamp 8 to be fitted onto the outside of the receiving pipe 2 simply by rotating the upper clamp ring 13 and the lower clamp ring 14 to open it. After fitting it onto the outside of the receiving pipe 2, the other end can be connected and fixed. The second locking clamp 8 is used to maintain the connection and fixation with the receiving pipe 2 and to provide a support point for the connection of the pull rod 4. Thus, the pull rod 4 can be used to connect and fix the discharge pipe 1 and the receiving pipe 2, making the connection and fixation with the receiving pipe 2 more convenient and faster.
[0025] Preferably, the ends of the upper hoop 13 and the lower hoop 14 are both welded or integrally formed with connecting plates 15. The two connecting plates 15 are fixedly connected by bolts. After the upper hoop 13 and the lower hoop 14 are combined, the two connecting plates 15 come into contact. At this time, bolts are used to pass through the two to fix them, so that the connection between the upper hoop 13 and the lower hoop 14 is tighter and more fitted, and the connection is more secure.
[0026] Preferably, the discharge pipe 1 is made of metal and the receiving pipe 2 is made of rubber. This material allows the receiving pipe 2 to be tightened after being sleeved on the discharge pipe 1, making the connection between the discharge pipe 1 and the receiving pipe 2 tighter and less prone to leakage, thus further ensuring the smoothness of discharge.
[0027] Working Principle: In this invention, after the receiving pipe 2 is fitted onto the outside of the discharging pipe 1, a first locking clamp 3 is fitted onto the outside of the receiving pipe 2. Specifically, by rotating, the left clamp 5 and right clamp 6 are opened and fitted onto the outside of the receiving pipe 2. Then, the locking rod 7 between the ends of the left clamp 5 and the right clamp 6 is used to lock them together, making the first locking clamp 3 more securely fitted onto the outside of the receiving pipe 2. This locks and fixes the connection between the discharging pipe 1 and the receiving pipe 2, ensuring the strength of the connection and reducing the risk of breakage. The probability of loosening or breaking at the joint is greatly reduced, thus improving the continuity of material feeding. A pull rod 4 is rotatably connected to the feeding pipe 1, and a second locking clamp 8 is provided at the other end of the pull rod 4. The second locking clamp 8 is sleeved on the outside of the receiving pipe 2. This structure uses the pull rod 4 to connect the feeding pipe 1 and the receiving pipe 2 axially, making it difficult for them to move relative to each other after being connected by the pull rod 4. This makes the structure at the joint more robust, effectively avoiding the probability of the joint breaking, and further ensuring the continuity and efficiency of material feeding.
