Description

Technical Field

[0001] This utility model relates to a heat fusion welding device for prefabricated polymer irregular-shaped irrigation canals, belonging to the technical field of prefabricated polymer irrigation canal welding equipment. Background Technology

[0002] Precast polymer irrigation canals are long, straight strips with a U-shaped cross-section, primarily used for farmland irrigation. During farmland water conservancy construction, multiple precast polymer irrigation canals, spliced ​​together end-to-end, facilitate the introduction of reservoir water into the fields for convenient irrigation. Due to the complex terrain in rural areas, precast polymer irrigation canals are not always laid in straight lines; some are irregularly shaped and require bends to adapt to the specific rural terrain.

[0003] The existing precast polymer-modified irregular-shaped irrigation canals are achieved by hot-melting two precast polymer-modified irrigation canals end to end. The specific welding process involves: bringing the head end of one straight precast polymer-modified irrigation canal at a certain angle to the tail end of another straight precast polymer-modified irrigation canal, and then manually using a spray gun to heat the ends to their melting point. After the head and tail ends are heated, the two straight precast polymer-modified irrigation canals are then quickly moved manually to join them end to end. After natural cooling, the precast polymer-modified irregular-shaped irrigation canal is formed. However, this process has several drawbacks. Due to individual differences, manual hot-melt operation with a spray gun is cumbersome, labor-intensive, and covers a small area, resulting in low efficiency. Furthermore, manual movement of the precast polymer-modified irrigation canals during splicing can easily cause angular misalignment, leading to inconsistent joint angles and affecting the subsequent installation of these canals in rural areas. Therefore, improvements are necessary. Summary of the Invention

[0004] The purpose of this utility model is to provide a hot-melt welding device for prefabricated polymer irrigation canals that effectively reduces manual labor, improves the efficiency of hot-melt welding, and solves the problem that angle deviation easily occurs during the manual splicing of existing prefabricated polymer irregular-shaped irrigation canals, resulting in inconsistent docking angles.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution.

One end of the guide rod is fixedly connected to a fixed frame, and the other end is connected to the base frame via a limiting sleeve and a limiting nut. Symmetrical receiving plates are fixedly mounted on the two cylinders. A third clearance recess is provided on the receiving plate, and a positioning rib groove C is provided within the third clearance recess corresponding to the positioning rib groove A.

[0025] The left frame plate 1 and the right frame plate 2 are connected by multiple connecting rods 9. The connecting rods 9 are bent to make the left frame plate 1 deflect at a certain angle relative to the right frame plate 2, thereby ensuring that the two straight precast polymer irrigation canals 7 on the left frame plate 1 and the right frame plate 2 are connected end to end at a certain angle.

[0026] A fixing frame 10 is fixedly installed inside the base frame. The fixing frame 10 is a rectangular plate. The fixing frame 10 is a rectangular plate. A fourth clearance recess 11 is provided on the fixing frame 10. A positioning rib groove D12 is provided in the fourth clearance recess 11 corresponding to the positioning rib groove B6. The positioning rib groove D12 has the same function as the positioning rib groove B6, which is used to position the straight polymer prefabricated irrigation canal 7.

[0027] The fixed frame 10 has locking rods B13 hinged at both ends, and locking nuts B14 are threaded onto the locking rods B13.

[0028] A movable assembly is installed in the base frame on one side of the fixed frame 10. The movable assembly includes two cylinders 15. Guide rods 16 are movably inserted into the two cylinders 15 through sealing rings. Pistons 17 are fixedly installed on the guide rods 16 in the cylinders 15. A first air inlet 18 and a second air inlet 19 are respectively installed at corresponding positions in the cavities of the cylinders 15 on both sides of the piston 17. In use, gas of different pressures is introduced into different cavities of the cylinders 15 through the first air inlet 18 and the second air inlet 19, so that the cylinders 15 slide to the left or right along the guide rods 16.

[0029] One end of each of the two guide air rods 16 is fixedly connected to the fixed frame 10. The other end of the guide air rod 16 is slidably inserted into the left frame plate 1 of the base frame and extends to the outside of the left frame plate 1. A limit sleeve 20 is fitted on the guide air rod 16 extending to the outside of the left frame plate 1. The limit sleeve 20 is in contact with the left frame plate 1. A limit nut 21 is threaded on one side of the guide air rod 16 of the limit sleeve 20. The limit nut 21 is in contact with the limit sleeve 20.

[0030] Two support plates 22 are symmetrically fixedly installed on the two cylinder blocks 15. The two support plates 22 are fixedly connected by a connecting rod. The purpose is to ensure the structural stability between the two support plates 22 through the connecting rod.

[0031] The receiving plate 22 is provided with a third clearance recess 23, and a positioning rib groove C24 is provided in the third clearance recess 23 corresponding to the positioning rib groove A5. The positioning rib groove C24 has the same function as the positioning rib groove A5, and is used to position the straight polymer prefabricated irrigation canal 7.

[0032] Locking rods A25 are hinged to both ends of the receiving plate 22, and locking nuts A26 are threaded onto the locking rods A25.

[0033] A positioning seat is symmetrically arranged on the base frame between the movable component and the fixed frame 10. The positioning seat includes a fixing block 27 and a positioning rod 28. The fixing block 27 is fixedly installed at the bend of the connecting rod 9, and the positioning rod 28 is fixedly installed on the fixing block 27. The positioning rod 28 is a long round rod.

[0034] A hot-melt assembly is detachably inserted into the positioning seat. The hot-melt assembly includes a hot-melt plate 29, which is semi-circular. A connecting seat 30 is provided on the hot-melt plate 29. Handles 31 are fixedly installed at both ends of the connecting seat 30. A power cord 32 is connected to the handle 31 and electrically connected to the hot-melt plate 29. A limiting seat 33 is fixedly installed on the connecting seat 30 on one side below the handle 31. A positioning groove is provided on the limiting seat 33 at the position corresponding to the positioning rod 28. In use, the hot-melt assembly is placed on the base frame between the moving component and the fixed frame 10 by inserting the slot of the connecting seat 30 into the positioning rod 28 of the positioning seat.

[0035] A first pressing plate 34 is detachably installed on the fixing frame 10. The first pressing plate 34 has a semi-circular cross-section and limit forks at both ends. The limit forks have a U-shaped cross-section. In use, the locking rod B13 of the fixing frame 10 is flipped into the fork groove of the limit fork of the first pressing plate 34, and then the locking nut B14 is tightened so that the locking nut B14 abuts against the limit fork of the first pressing plate 34, thereby realizing the pressing of the straight polymer prefabricated irrigation canal 7 by the fixing frame 10 and the first pressing plate 34.

[0036] The structure of the second pressing plate is the same as that of the first pressing plate 34. The cross-section of the second pressing plate is semi-circular, and the two ends of the second pressing plate are respectively provided with limit forks. The cross-section of the limit forks is U-shaped. In use, by flipping the locking rod A25 of the receiving plate 22 into the fork groove of the limit fork of the second pressing plate, and then tightening the locking nut A26, the locking nut A26 is made to abut against the limit fork of the first pressing plate 34, thereby realizing the pressing of the straight polymer prefabricated irrigation canal 7 by the receiving plate 22 and the second pressing plate.

[0037] When using the heat fusion welding device for the prefabricated polymer irrigation canal, the first straight prefabricated polymer irrigation canal 7 is first placed on the two receiving plates 22 and the left frame plate 1 of the moving component, so that the ribs 8 on the first straight prefabricated polymer irrigation canal 7 correspond to the first relief recess 3 of the left frame plate 1 and the third relief recess 23 of the receiving plate 22, thereby making the left frame plate 1 and the receiving plate 22 support the first straight prefabricated polymer irrigation canal 7. Then, the two second pressing plates are respectively placed on the first straight prefabricated polymer irrigation canal 7, corresponding to the receiving plate 22. The locking rod A25 of the receiving plate 22 is flipped into the fork groove of the limiting fork of the second pressing plate, and then the locking nut A26 is tightened, so that the locking nut A26 abuts against the limiting fork of the first pressing plate 34, thereby realizing the pressing of the straight prefabricated polymer irrigation canal 7 by the receiving plate 22 and the second pressing plate.

[0038] Next, the second straight precast polymer irrigation canal 7 is placed on the fixing frame 10 and the right frame plate 2, so that the ribs 8 on the second straight precast polymer irrigation canal 7 correspond to the fourth relief recess 11 of the fixing frame 10 and the second relief recess 4 of the right frame plate 2, thereby making the fixing frame 10 and the right frame plate 2 support the second straight precast polymer irrigation canal 7. Then, a first pressing plate 34 is placed on the second straight precast polymer irrigation canal 7, corresponding to the fixing frame 10. The locking rod B13 of the fixing frame 10 is flipped into the fork groove of the limiting fork of the first pressing plate 34, and the locking nut B14 is tightened, so that the locking nut B14 abuts against the limiting fork of the first pressing plate 34, thereby realizing the pressing of the second straight precast polymer irrigation canal 7 by the fixing frame 10 and the first pressing plate 34.

[0039] After the first and second straight precast polymer irrigation channels 7 are placed in place, the hot-melt assembly is inserted into the positioning seat. The hot-melt plate 29 of the hot-melt assembly contacts and connects with one end of the first and second straight precast polymer irrigation channels 7, respectively. When the power cord 32 is powered on, the hot-melt plate 29 begins to heat up. The second air inlet 19 is controlled to supply air, and the pressure in the cavity of the cylinder 15 on the right side of the piston 17 increases to the cavity of the cylinder 15 on the left side of the piston 17. The cylinder 15 moves to the right along the guide rod 16. At this time, the receiving plate 22 on the cylinder 15... The cylinder 15 moves to the right in sync with the first straight precast polymer irrigation channel 7 until the end face of the first straight precast polymer irrigation channel 7 is completely melted and reaches a suitable melting point. Then, the hot-melt assembly is removed. As the cylinder 15 continues to move, the molten tail end of the first straight precast polymer irrigation channel 7 contacts and connects with the molten head end of the second straight precast polymer irrigation channel 7. After the first and second straight precast polymer irrigation channels 7 cool and solidify naturally, a precast polymer irregular-shaped irrigation channel is obtained. The above steps are repeated to start the welding operation of the next precast polymer irregular-shaped irrigation channel.

[0040] This hot-melt welding device effectively reduces manual labor and improves the efficiency of hot-melt welding. At the same time, it solves the problem that angle deviation easily occurs during the manual splicing of existing prefabricated irregular-shaped irrigation canals, resulting in inconsistent docking angles.
