Description

Technical Field

[0001] This invention relates to the field of seepage irrigation technology, specifically to a deep-buried seepage irrigation pipe laying machine. Background Technology

[0002] Drip irrigation introduces irrigation water to a certain depth below the field surface, moistening the root zone soil through capillary action to meet the needs of crop growth. Chinese Patent CN201822137646.0 discloses a drip irrigation pipe laying machine, including a frame, power transmission box, cutter head assembly, drip irrigation pipe disc, and backfill shovel. The cutter head assembly consists of a cutter head and trenching blades; multiple trenching blades are evenly distributed along the circumference of the cutter head. Trenching is performed by the trenching blades of the cutter head assembly, and backfilling is done by the backfill shovel. This technical solution can achieve underground laying of drip irrigation pipes, solving the problem of low efficiency in manual laying. Its drawback is that it can generally only bury drip irrigation pipes shallowly. If the drip irrigation pipe is buried deeply (e.g., to a depth of 60cm), the size of the trenching blades must be larger, resulting in a larger overall height of the laying machine and requiring greater power output to break up the soil. In addition, in the existing technology, when the drip irrigation pipe is buried deep, the deep soil is broken up by a plow. The unevenness of the shallow soil clods causes the laying machinery to rise and fall, which in turn makes the burial depth of the drip irrigation pipe inconsistent. Summary of the Invention

[0003] The purpose of this invention is to provide a deep-buried drip irrigation pipe laying machine, which is applied to the deep-buried drip irrigation pipe laying operation. By breaking up the shallow soil, the influence of shallow hard soil blocks on the stability of the laying machine is reduced, so as to ensure the consistency and accuracy of the deep-buried drip irrigation pipe laying depth.

[0004] The technical solution adopted by this invention to solve its technical problem is: a deep-buried drip irrigation pipe laying machine, including a frame, a drip irrigation pipe frame, and a trenching and pipe laying assembly. The front end of the frame is connected to a traction vehicle, the drip irrigation pipe frame is located at the rear end of the frame, and a drip irrigation pipe reel is rotatably mounted on the drip irrigation pipe frame. The trenching and pipe laying assembly is located in the middle of the frame and has a guide channel. The drip irrigation pipe on the drip irrigation pipe reel moves along the guide channel. The machine also includes a crushing assembly, which includes a crushing box, a crushing shaft, crushing components, a main shaft, and a transmission unit. The crushing box is fixed to the front end of the frame, the crushing shaft is rotatably mounted inside the crushing box, and the crushing components are multiple components fixed on the crushing shaft and evenly arranged along the axial direction of the crushing shaft. The number of crushing components is equal to the number of drip irrigation pipe reels. A transmission box is located at the top of the frame. One end of the main shaft is connected to the output end of the traction vehicle, and the other end of the main shaft is rotatably connected to the transmission box. The transmission unit is located between the other end of the main shaft and the crushing shaft. The crushing components crush the shallow soil as the crushing shaft rotates.

[0005] Furthermore, the crushing component includes a central cylinder and plate-shaped shovel blades. The central cylinder has a cylindrical structure, and the shovel blades are evenly arranged circumferentially with one end fixedly connected to the outer wall of the central cylinder. The other end of the shovel blades is arc-shaped, and each pair of adjacent shovel blades is fixedly connected by a blade connecting plate.

[0006] Furthermore, the inner side of the other end of the shovel blade has a "V"-shaped cutting blade, and the large end of the cutting blade is fixedly connected to the other end of the shovel blade.

[0007] Furthermore, the transmission unit includes a worm gear, a worm, and a chain drive mechanism. The worm gear is fixed on the crushing shaft, the worm is rotatably installed inside the crushing box and meshes with the worm gear, and the chain drive mechanism is located between the main shaft and the worm shaft of the worm.

[0008] Furthermore, the trenching and pipe-laying assembly includes, from top to bottom, an installation block, a plow fixing rod, a plow movable rod, and a trenching plow. The plow fixing rod is fixedly connected to the installation block, and the upper end of the plow movable rod is located inside the plow fixing rod and slidably connected to it. A locking fastener is provided between the plow movable rod and the plow fixing rod, and the trenching plow is fixed to the bottom of the plow movable rod. The top of the installation block has a guide bucket, and the trenching plow has a guide wheel inside. The installation block has a through hole running vertically through it, and the through hole forms a guide channel with the inner cavity of the plow fixing rod, the inner cavity of the plow movable rod, and the inner cavity of the trenching plow. The drip irrigation pipe is introduced into the upper end of the guide channel from the guide bucket.

[0009] Furthermore, the plow lever has a triangular structure, and one side edge of the plow lever has a cutting edge facing the front of the frame.

[0010] Furthermore, the furrowing plow has a triangular frustum structure, and there are partitions on the left and right side walls of the furrowing plow. The partitions are set at an acute angle to the horizontal plane, and the lower end of the partitions faces the front end of the furrowing plow.

[0011] Furthermore, the partitions on each side wall of the furrowing plow are two pieces arranged vertically, with the lower end of the upper partition intersecting the side edge of the furrowing plow and the lower end of the lower partition intersecting the bottom edge of the furrowing plow.

[0012] Furthermore, one end of the drip irrigation pipe rack is hinged to the machine frame, the other end of the drip irrigation pipe rack is used to install the drip irrigation pipe reel, and a tilting cylinder is provided between one end of the drip irrigation pipe rack and the machine frame.

[0013] Furthermore, the drip irrigation pipe frame includes side rods, cross rods, and extension rods. The side rods are two parallel rods. The cross rod is located between the two side rods and is fixedly connected to the side rods. The extension rod is fixed to the cross rod at one end of the drip irrigation pipe frame. The drip irrigation pipe reel is located between the ends of the two side rods. The extension rod is hinged to the piston rod of the tilting cylinder. The cylinder of the tilting cylinder is hinged to the frame.

[0014] The beneficial effects of this invention are as follows: This invention enables the deep burial of the drip irrigation pipe by setting up the trenching and pipe laying assembly, and the crushing assembly set in front of the trenching and pipe laying assembly crushes the shallow soil layer. On the one hand, this reduces the resistance of the trenching and pipe laying assembly during its movement, and on the other hand, by crushing and loosening the shallow soil layer, it reduces the impact of shallow hard soil clods on the stability of the laying machinery, thereby ensuring the laying accuracy and depth consistency of the drip irrigation pipe.

[0035] like Figures 1 to 19 As shown, the present invention includes a frame 1, a trenching and pipe-laying assembly, a crushing assembly, and an irrigation pipe rack 5. The present invention will be described in detail below with reference to the accompanying drawings.

[0036] like Figures 1 to 5 As shown, the deep-buried drip irrigation pipe laying machinery includes a frame 1, a drip irrigation pipe frame 5, and a trenching and pipe-laying assembly. The front end of the frame 1 is connected to a traction vehicle. Specifically: Figure 1As shown, the front end of the frame 1 has a front ear plate 11, and the top of the front end of the frame 1 has a square support frame 13. The bottom of the support frame 13 is fixedly connected to the frame 1, and the top of the support frame 13 has a support frame ear plate 14. The front ear plate 11 is used to connect with the body hinge of the traction vehicle, and the support frame ear plate 14 is used to connect with the hydraulic cylinder hinge on the traction vehicle. The inner side of the support frame 13 is provided with a cross-shaped reinforcement member 15. The four ends of the reinforcement member 15 contact the inner wall of the support frame 13. The reinforcement member 15 is provided to increase the structural strength of the support frame 13.

[0037] The frame 1 has a square frame structure. The inner side of the rear end of the frame 1 has multiple mounting arms 17. The mounting arms 17 are provided to increase the structural strength of the frame 1 and facilitate the installation of other components.

[0038] like Figures 1 to 5 As shown, the drip irrigation pipe rack 5 is located at the rear end of the frame 1. A drip irrigation pipe reel 8 is rotatably mounted on the drip irrigation pipe rack 5, and drip irrigation pipe is wound on the reel 8. One end of the drip irrigation pipe rack 5 is hinged to the rear ear plate 12 at the rear end of the frame 1, and the other end of the drip irrigation pipe rack 5 is used to mount the drip irrigation pipe reel 8. A tilting cylinder 6 is located between one end of the drip irrigation pipe rack 5 and the frame 1. Specifically: Figure 12 As shown, the drip irrigation pipe frame 5 includes side rods 51, cross rods 52, and outriggers 53. The side rods 51 are two parallel rods, one end of which is hinged to the rear ear plate 12. The cross rods 52 are located between the two side rods 51 and fixedly connected to them. Multiple cross rods 52 are evenly spaced. The outriggers 53 are fixed to the cross rods 52 at one end of the drip irrigation pipe frame 5 connected to the frame 1 and are perpendicular to the cross rods 52. The drip irrigation pipe reel 8 is located between the other ends of the two side rods 51. The outriggers 53 are hinged to the piston rod of the tilting cylinder 6. The cylinder of the tilting cylinder 6 is hinged to the cylinder ear plate 61 on one of the mounting arms 17. Figure 4 As shown, when the piston rod of the tilting cylinder 6 retracts, the irrigation pipe rack 5 is in a vertical position; as Figure 11 As shown, after the piston rod of the tilting cylinder 6 is fully extended, the irrigation pipe rack 5 is tilted and the irrigation pipe reel 8 at one end of the irrigation pipe rack 5 is close to the ground, which makes it easy to replace and install the irrigation pipe reel 8.

[0039] like Figure 10 As shown, the drip irrigation pipe reel 8 is used to wind the drip irrigation pipe 10, as follows: Figure 1As shown, the drip irrigation pipe reel 8 includes a reel 81, a baffle 82, a pipe winding shaft 83, support rods 84, and an outer ring 85. The baffle 82 has a circular structure with a circular hole in its center. Two baffles 82 are arranged in parallel, and multiple pipe winding shafts 83 are located between the two baffles 82. The pipe winding shafts 83 are evenly arranged circumferentially, and their ends are in contact with and fixed to the corresponding baffles 82. When winding the drip irrigation pipe 10, the innermost drip irrigation pipe 10 is in contact with the pipe winding shaft 83, and the cylindrical structure formed by the pipe winding shaft 83 serves as support for winding the drip irrigation pipe 10. Several support rods 84 are provided on the circular outer wall of the baffle 82. On the one hand, the support rods 84 are evenly arranged circumferentially; on the other hand, the support rods 84 are also arranged radially along the baffle 82. The outer ring 85 is a circular structure located around the entire drip irrigation pipe reel. The support rod 84 is positioned between the outer ring 85 and the baffle 82, securing the outer ring 85 to the baffle 82 and providing a blocking effect for the drip irrigation pipe 10. To achieve the assembly between the drip irrigation pipe reel 8 and the drip irrigation pipe frame 5, as follows... Figure 12 As shown, a handle 86 is fixed at one end of the reel 81, and a nut 87 is provided at the other end of the reel 81. During installation, the drip irrigation pipe reel 8 is first placed between the ends of the two side rods 51. Then, holding the handle 86 at one end of the reel 81, the other end of the reel 81 is inserted into the round hole at the end of one of the side rods 51, and then sequentially passes through the round holes on the two baffles 82 and the round hole at the end of the other side rod 51, until the other end of the reel 81 extends out of the other side rod 51. Then, the nut 87 is installed at the other end of the reel 81 to limit the reel 81 and the side rod 51 along the axial direction of the reel 81.

[0040] like Figure 4 As shown, the trenching and pipe-laying assembly is located in the middle of frame 1, as... Figure 8 , Figure 9 As shown, the trenching and pipe-laying assembly has a guide channel along which the irrigation pipe 10 on the irrigation pipe reel 8 moves. Figure 7 , Figure 8As shown, the trenching and pipe-laying assembly includes, from top to bottom, an installation block 43, a plow fixing rod 42, a plow movable rod 41, and a trenching plow 4. The installation block 43 has a rectangular parallelepiped structure, with a rectangular insertion hole 431 at each end. The upper end of the plow fixing rod 42 is fixedly connected to the installation block 43, and the upper end of the plow movable rod 41 is located inside the plow fixing rod 42 and slidably connected to it. The inner side of the plow fixing rod 42 has a groove for sliding connection with the plow movable rod 41. The trenching plow 4 is fixed to the bottom of the plow movable rod 41. A locking fastener, which is a bolt, is provided between the plow movable rod 41 and the plow fixing rod 42 to achieve locking and fixing between them. When it is necessary to adjust the relative position between the plow movable rod 41 and the plow fixed rod 42, i.e., to adjust the height of the furrowing plow 4, loosen the locking fastener, move the plow movable rod 41 up and down until it is in the appropriate position, and then lock the plow movable rod 41 and the plow fixed rod 42 again using the locking fastener, thereby achieving the adjustment of the burial depth of the irrigation pipe. The top of the mounting block 43 has a guide bucket 44, which is a funnel-shaped structure. The small end of the guide bucket 44 is in contact with and fixed to the mounting block 43, and the large end of the guide bucket 44 faces upward. A guide wheel 45 is rotatably installed inside the furrowing plow 4. The mounting block 43 has a through hole that runs vertically through the plow. The through hole forms a guide channel with the inner cavity of the plow fixed rod 42, the inner cavity of the plow movable rod 41, and the inner cavity of the furrowing plow 4. Figure 9 As shown, the drip irrigation pipe 10 is introduced into the upper end of the guide channel from the guide hopper 44, and then contacts the guide wheel 45 at the lower end of the guide channel. The guide wheel 45 is used to change the direction and guide the drip irrigation pipe 10. Figure 9 , Figure 13 As shown, in order to reduce the friction between the drip irrigation pipe 10 and the guide hopper 44, a smooth outer wall pad 47 is also provided on the inner wall of the guide hopper 44. The upper end of the guide hopper 44 is large, which is conducive to the drip irrigation pipe 10 extending into the guide channel; the pad 47 can reduce the friction between the drip irrigation pipe 10 and the guide hopper 44.

[0041] like Figure 7 As shown, the plow lever 41 has a triangular structure. The side edge of the plow lever 41 facing the front of the frame 1 has a blade 411. The blade 411 faces the front of the frame 1 and, when the frame 1 moves forward, it can cut the soil and push the soil to both sides. The furrowing plow 4 has a triangular frustum structure, as shown... Figure 16 , Figure 17 As shown, the left and right sidewalls of the furrowing plow 4 are soil-turning surfaces 46, and each soil-turning surface 46 has a partition 7. The partition 7 is set at an acute angle to the horizontal plane, and the lower end of the partition 7 faces the front end of the furrowing plow 4. Each sidewall of the furrowing plow 4 has two partitions 7, one above the other. The lower end of the upper partition 7 intersects with the forward-facing side edge of the furrowing plow 4, and the lower end of the lower partition 7 intersects with the bottom edge of the furrowing plow 4. Figure 18As shown, when the furrowing plow 4 moves forward, the soil 9 is cut by the blades on the side of the furrowing plow 4, and the soil 9 is also cut into multiple layers by the partition 7. Thus, as... Figure 18 As shown, on the one hand, soil 9 moves from top to bottom along the partition, as... Figure 19 As shown, on the other hand, after the soil 9 is cut by the blade, it moves to both sides of the furrowing plow 4, which makes it easy to form cavities in the path of the furrowing plow 4 or the soil that the furrowing plow passes through becomes loose, thus reducing the pressure on the drip irrigation pipe after it is laid, which is conducive to the normal infiltration of water in the drip irrigation pipe.

[0042] The most prominent difference between this invention and existing technologies also includes the inclusion of a crushing component, such as... Figures 1 to 4 , Figure 6 As shown, the crushing assembly includes a crushing box 2, a crushing shaft 22, crushing parts 23, a main shaft 3, and a transmission unit. The crushing box 2 is a hollow cuboid structure with an open bottom. The top of the crushing box 2 has a crushing box mounting plate 21, which is a rectangular plate. The length of the crushing box mounting plate 21 is greater than the length of the crushing box 2, and the width of the crushing box mounting plate 21 is greater than the width of the crushing box 2. Figure 5 As shown, the inner side of the frame 1 is provided with a mounting step 18, which is essentially a rectangular metal frame. During installation, the crushing box 2 is extended out from the inner side of the mounting step 18 until the edge of the crushing box mounting plate 21 contacts the upper surface of the mounting step 18, and the crushing box mounting plate 21 is positioned at the front end of the frame 1. Bolts are then installed between the edge of the crushing box mounting plate 21 and the mounting step 18 to achieve relative fixation between the crushing box 2 and the frame 1. Figure 6 As shown, the crushing shaft 22 is rotatably installed inside the crushing box 2. Multiple crushing components 23 are fixed to the crushing shaft 22 and evenly arranged along its axial direction. The number of crushing components 23 is equal to the number of irrigation pipe reels 8. Figure 14 As shown, the crushing component 23 includes a central cylinder 231 and plate-shaped shovel blades 232. The central cylinder 231 has a cylindrical structure. The shovel blades 232 are evenly arranged circumferentially, with one end of each blade fixedly connected to the outer wall of the central cylinder 231 and the other end of each blade being arc-shaped. Each pair of adjacent shovel blades 232 is fixedly connected by a blade connecting plate 233. The blade connecting plate 233 is an arc-shaped metal plate, and its arrangement enhances the structural strength of the entire crushing component 23. Figures 1 to 5 As shown, the top of the frame 1 has a transmission box 29. One end of the main shaft 3 is used to connect to the output end of the traction vehicle, and the other end of the main shaft 3 is rotatably connected to the transmission box. The transmission unit is set between the other end of the main shaft 3 and the crushing shaft 22. When the crushing piece 23 rotates with the crushing shaft 22, it shovels and throws the shallow soil, thereby crushing the shallow soil.

[0043] To further enhance the breaking effect on shallow soil, such as Figure 15 As shown, the inner side of the other end of the shovel blade 232 has a "V"-shaped cutting blade 234, the larger end of which is fixedly connected to the other end of the shovel blade 232. The edge of the larger end of the cutting blade 234 is arc-shaped, which can perfectly fit with the other end of the shovel blade 232, facilitating welding. When the shovel blade 232 digs the soil, the smaller end of the cutting blade 234 can cut the soil, which is beneficial for soil breaking.

[0044] To achieve power transmission between the drive shaft 3 and the crushing shaft 22, such as Figure 6 As shown, the transmission unit includes a worm gear 24, a worm 25, and a chain drive mechanism. The worm gear 24 is fixed on the crushing shaft 22. The worm shaft 251 of the worm 25 is rotatably installed inside the crushing box 2, and the worm 25 meshes with the worm gear 24. The chain drive mechanism is located between the main shaft 3 and the worm shaft 251 of the worm 25. The chain drive mechanism includes a driven sprocket 27 coaxially arranged with the worm shaft 251, a driving sprocket 31 coaxially arranged with the main shaft 3, and a chain 28 disposed between the driving sprocket 31 and the driven sprocket 27. One end of the main shaft 3 is connected to the power output end of the traction vehicle via a coupling. When the main shaft 3 rotates, it drives the worm 25 to rotate through the chain drive mechanism, which in turn drives the worm gear 24 to rotate, which in turn drives the crushing shaft 22 to rotate, which in turn drives the crushing component 23 to rotate. During the rotation of the crushing component 23, the shallow soil is crushed. To support the worm shaft 251, as shown... Figure 6 As shown, a shaft support 26 is provided inside the crushing box 2. One end of the shaft support 26 is fixedly connected to the crushing box 2, and the other end of the shaft support 26 is rotatably connected to the worm shaft 251. To facilitate the assembly of the main shaft 3, as shown... Figure 1 As shown, the center of the reinforcement 15 has a central ring 16, and one end of the main shaft 3 extends forward after passing through the central ring 16.

[0045] The working principle of the present invention is described below: Figure 10As shown, after connecting the front end of the frame 1 to the traction vehicle, the traction vehicle moves the entire frame forward. At this time, the crushing component 23 rotates, crushing the shallow soil 20 (soil 0-30cm below the surface). Simultaneously, the trenching plow 4 crushes the deep soil 19 (soil 30-60cm below the surface). As the frame 1 moves forward, the irrigation pipe 10, pressed down by the soil, pulls the irrigation pipe reel 8 to rotate, causing the irrigation pipe 10 on the reel 8 to be continuously disassembled and moved through the guide channel, eventually being buried in the trench dug by the trenching plow 4. The trenching plow 4 crushes, loosens, and pushes the lower soil layer, placing the buried irrigation pipe 10 in a loose environment, facilitating normal water infiltration within the pipe. The crushing component also reduces the degree of soil compaction in the shallow soil layer. Since the crushing component is located in front of the trenching and laying component, the crushing component first crushes the shallow soil 20, thereby reducing the resistance when the plowing rod 41 of the trenching and laying component moves.

[0046] This invention utilizes a trenching and pipe-laying assembly to deeply bury irrigation pipes. A crushing component positioned in front of this assembly breaks up the shallow soil, reducing resistance during the assembly's movement and mitigating the impact of hard soil layers on the stability of the laying machinery. Large soil clods can cause unevenness in the laying machinery, leading to inconsistent pipe-laying depths. Breaking up the shallow soil ensures smooth movement and consistent pipe-laying depth. Loosening the shallow soil also prevents compaction. The structure of the trenching and pipe-laying assembly allows for adjustment of the burial depth. The sidewall baffles of the trenching plow facilitate cutting and lifting of deeper soil, creating trenches along the plow's path and reducing pressure on the irrigation pipes after laying.
