Description

Technical Field

[0001] This invention relates to the field of saline-alkali land improvement technology, and more specifically, to a manufacturing equipment and method for a blind water conduit used in saline-alkali land improvement. Background Technology

[0002] Saline-alkali land is a special type of land widely existing globally, with excessive soluble salts in its soil, which severely inhibits plant growth. With continuous population growth and rapid economic development, land resources are becoming increasingly scarce, making the transformation and development of saline-alkali land, as a potential usable land resource, particularly important. Water conservancy improvement technology is an important method for improving saline-alkali land. To overcome the problem of salinity rebound in existing water conservancy improvement technologies, the inventor proposed a blind water-conducting pipe and filed a patent application on the same day as this case. Due to the special structure of this blind water-conducting pipe, there is a lack of production equipment for it in the existing technology. Summary of the Invention

[0003] This invention provides a manufacturing equipment and method for a water-conducting blind pipe used for saline-alkali land improvement, which improves upon the lack of such production equipment in the prior art and can be used for the production of the water-conducting blind pipe.

[0004] To achieve the above objectives, in a first aspect, the present invention provides a manufacturing apparatus for a blind drainage pipe for saline-alkali land improvement, comprising:

[0005] A clamping device, the clamping device comprising two opposing and rotatably disposed chucks;

[0006] A guiding device is disposed between the two chucks. The guiding device includes two clamping arms, which are arranged radially opposite to each other along the chucks. Each clamping arm includes a hinge portion, an arched portion, and an end portion connected in sequence. The hinge portion is rotatably arranged in a direction that moves away from or closer to each other along the two end portions. The arched portions of the two clamping arms are arched in an arc shape in opposite directions. The line connecting the two chucks passes through the space between the two arched portions. The two end portions are arranged radially spaced along the chucks to allow the space to communicate with the outside. In use, two chucks clamp both ends of the central rod, and then the outer peripheral rods are inserted into the gap between the two ends in sequence. Due to the constraint of the two arched parts, the outer peripheral rods will be distributed around the central rod and temporarily fixed. At this time, the outer peripheral rods can be tied more easily, thereby fixing the outer peripheral rods to the outside of the central rod. Since the central rod and the outer peripheral rods are fixed by the chucks and the bottom is suspended, it is also easier to wrap straw mats and bamboo mats around the outer peripheral rods and fix them.

[0007] As an optional technical solution, the guiding device further includes a rotating seat, a connecting rod, and a linear drive component. The hinged portion is rotatably connected to the rotating seat at the connection point with the arched portion. The end of the hinged portion is hinged to one end of the connecting rod, and the other end of the connecting rod is connected to the linear drive component. The linear drive component is disposed between the two clamping arms and is arranged radially along the chuck. The linear drive component can drive the clamping arms to open and close, allowing for convenient unloading after the outer peripheral rod is fixed.

[0008] As an optional technical solution, the guiding device further includes a slide rail and a limiting structure. The slide rail is arranged along the movement direction of the linear drive member, the rotating seat is slidably disposed on the slide rail, and the limiting structure is disposed at both ends of the slide rail. The limiting structure is disposed on the side of the slide rail facing the arched portion. The distance from the limiting structure to the line connecting the two chucks corresponds to the radius of curvature of the arched portion. Multiple guiding devices are provided, spaced apart along the line connecting the two chucks. The radius of curvature of the arched portion on any two guiding devices is different. In some technical solutions, this water-guiding blind pipe can have multiple layers of nested outer peripheral rods, each with a different diameter of its circumscribed circle. Therefore, multiple guiding devices with different radii of curvature can constrain and guide the outer peripheral rods when assembling different layers of outer peripheral rods.

[0009] As an optional technical solution, the guiding device further includes a return spring, which is disposed at the connection between the hinge and the rotating seat. The return spring is used to move the two clamping arms away from each other. After the outer peripheral rod is installed, the linear drive retracts to the side away from the rotating seat. Due to the action of the return spring, the two clamping arms will first move away from each other, and then the rotating seat will descend along the slide rail. This helps to avoid scraping or damaging the water guide blind pipe when the guiding device retracts.

[0010] As an optional technical solution, an open-type strapping device is also included. This device is positioned between the two chucks, with its loading port corresponding to the interval between the two ends. When the outer peripheral rod is inserted into the guiding device, the loading port of the open-type strapping device can avoid the path of the outer peripheral rod, thus simplifying the assembly of the blind water guide pipe.

[0011] As an optional technical solution, a guide rail is also included, which is arranged along the line connecting the two chucks, and the open-type strapping device is slidably disposed on the guide rail. The open-type strapping device can slide along the axial direction of the water-guiding blind pipe via the guide rail, thereby allowing a single open-type strapping device to perform multiple strapping operations along the axial direction on the water-guiding blind pipe, which helps to reduce the complexity and cost of the manufacturing equipment.

[0012] As an optional technical solution, the clamping device further includes a rotating shaft rotatably connected to the chuck. After the outer peripheral rod is fixed to the outer periphery of the central rod, the chuck can be rotated to cover the outer peripheral rod with straw mats and bamboo mats, which helps to simplify the operation of assembling the blind water pipe.

[0013] Secondly, the present invention also provides a method for manufacturing a blind drainage pipe for saline-alkali land improvement, applied to the manufacturing equipment described in any of the above technical solutions, comprising the following steps:

[0014] S1: Install both ends of the central rod onto the two chucks respectively;

[0015] S2: Insert the outer peripheral rods into the space from the gap between the two ends in sequence, and arrange the outer peripheral rods so that they are circumferentially arranged along the inner wall of the space;

[0016] S3: Bind the outer peripheral rods;

[0017] S4: Cover the outer perimeter of the outer rod with straw mats and bamboo mats, and secure them in place.

[0018] As an optional technical solution, step S2 includes:

[0019] S21: Insert the outer peripheral rod into the space through the gap between the two ends, and position the bamboo pole at the bottom of the space;

[0020] S22: Continue to insert the outer peripheral rod into the space from the gap between the two ends, so that the subsequently inserted outer peripheral rod pushes the previously inserted outer peripheral rod toward one of the clamping arms until the space is filled.

[0021] As an optional technical solution, the clamping device further includes a rotating shaft, which is rotatably connected to the chuck; step S4 includes: rotating the rotating shaft to rotate the central rod and the outer peripheral rod; and winding and fixing the straw mat and bamboo mat around the outer peripheral rod.

[0022] One or more technical solutions provided by this invention have at least the following technical effects or advantages:

[0023] This invention discloses a manufacturing equipment and method for a blind drainage pipe used in saline-alkali land improvement. The manufacturing equipment includes a clamping device and a guiding device. The clamping device has two opposing and rotatably arranged chucks. The guiding device is located between the two chucks and includes two clamping arms arranged radially opposite to each other. Each clamping arm consists of a hinge, an arched portion, and an end portion connected in sequence. The hinge is rotatably arranged in a direction that moves away from or closer to each other at the two ends. The two arched portions are opposite to each other and form an arc shape. The line connecting the two chucks passes through the space between the two arched portions, and the two ends are arranged radially apart to allow this space to communicate with the outside. In use, the two chucks clamp the two ends of the central rod, and the outer peripheral rods are inserted through the gap between the two ends. Constrained by the arched portions, they automatically distribute around the central rod and are temporarily fixed, facilitating quick bundling and subsequent wrapping with straw mats and bamboo mats. This equipment significantly improves the efficiency and convenience of manufacturing blind drainage pipes. Attached Figure Description

[0043] Example 1

[0044] This embodiment provides a manufacturing apparatus for a blind drainage pipe used in saline-alkali land improvement, comprising:

[0045] The clamping device includes two opposing and rotatably arranged chucks 11;

[0046] A guiding device 2 is disposed between two chucks 11. The guiding device 2 includes two clamping arms 21, which are arranged radially opposite to each other along the chucks 11. Each clamping arm 21 includes a hinge portion 211, an arched portion 212, and an end portion 213 connected in sequence. The hinge portion 211 is rotatably arranged in a direction that moves away from or closer to each other along the two end portions 213. The arched portions 212 of the two clamping arms 21 are arched in an arc shape in opposite directions. The line connecting the two chucks 11 passes through the space between the two arched portions 212. The two end portions 213 are arranged radially spaced along the chucks 11 to allow the space to communicate with the outside. In use, the two chucks 11 clamp the two ends of the central rod 101, and then the outer peripheral rods 102 are inserted into the gap between the two ends 213 in sequence. Due to the constraint of the two arched parts 212, the outer peripheral rods 102 will be distributed around the central rod 101 and temporarily fixed. At this time, the outer peripheral rods 102 can be tied more easily, thereby fixing the outer peripheral rods 102 to the outer periphery of the central rod 101. Since the central rod 101 and the outer peripheral rods 102 are fixed by the chucks 11 and the bottom is suspended, it is also easier to wrap straw mats and bamboo mats around the outer peripheral rods 102 and fix them.

[0047] As an optional implementation, the clamping device also includes a rotating shaft rotatably connected to the chuck 11. After the outer peripheral rod 102 is fixed to the outer periphery of the central rod 101, the chuck 11 can be rotated to cover the outer peripheral rod 102 with straw mats and bamboo mats, which helps to simplify the operation of assembling the blind water pipe 100.

[0048] Preferably, the axes of rotation of the two chucks 11 and the axis of the space between the two arched portions 212 are coaxially arranged.

[0049] In addition, the end portion 213 may be provided with a guide structure that extends away from the hinge portion 211.

[0050] Example 2

[0051] Based on Embodiment 1, the guiding device 2 further includes a rotating seat 22, a connecting rod 23, and a linear drive member 24. The hinge portion 211 and the arched portion 212 are rotatably connected to the rotating seat 22. The end of the hinge portion 211 is hinged to one end of the connecting rod 23, and the other end of the connecting rod 23 is connected to the linear drive member 24. The linear drive member 24 is disposed between the two clamping arms 21 and is arranged radially along the chuck 11. The linear drive member 24 can drive the clamping arms 21 to open and close, and after the outer peripheral rod 102 is fixed, the material can be unloaded more conveniently.

[0052] The linear drive component 24 can be a cylinder, an electric actuator, or a hydraulic rod, etc., and this embodiment does not impose any restrictions.

[0053] As an optional implementation, the guiding device 2 further includes a slide rail 25 and a limiting structure 26. The slide rail 25 is arranged along the movement direction of the linear drive member 24, the rotating seat 22 is slidably arranged on the slide rail 25, and the limiting structure 26 is arranged at both ends of the slide rail 25. The limiting structure 26 is arranged on the side of the slide rail 25 facing the arched portion 212. The distance from the limiting structure 26 to the line connecting the two chucks 11 corresponds to the radius of curvature of the arched portion 212. There are multiple guiding devices 2, which are spaced apart along the line connecting the two chucks 11. The radius of curvature of the arched portion 212 on any two guiding devices 2 is different. In some embodiments, the water guide blind pipe 100 may have multiple layers of nested outer peripheral rods 102, in which case the diameter of the circumscribed circle of each layer of outer peripheral rods 102 is different. Therefore, multiple guiding devices 2 with different radii of curvature can constrain and guide the outer peripheral rods 102 when assembling different layers of outer peripheral rods 102. The limiting structure 26 can be a stop block installed on the slide rail 25 at the end of the stroke of the rotating seat 22 using bolts or other locking components, or it can be a quick-adjustable limiting screw, etc. The number of guiding devices 2 can be set according to the number of layers of outer peripheral rods 102 in the water guide blind pipe 100. If necessary, a clearance groove can be provided on the rotating seat 22 or the slide rail 25 and the limiting structure 26 can be offset to prevent interference with the water guide blind pipe 100 under manufacturing.

[0054] In some implementations, the slide rail 25 may be a telescopic guide rail 4 to avoid interference with the blind water pipe 100.

[0055] As an example, assume that the water-conducting blind pipe 100 is provided with two layers of outer peripheral rods 102 nested sequentially, and the diameters of the circumscribed circles of the two layers of outer peripheral rods 102 from the inside to the outside are a and b respectively, where a < b; then in the corresponding embodiment, two sets of guiding devices 2 may be provided, wherein the curvature radius of the arch portion 212 of one of the guiding devices 2 is set corresponding to a, and when the rotating seat 22 of said guiding device 2 slides to the side away from the linear driving member 24, the diameter of the inscribed circle formed by the arch portion 212 and the rotating seat 22 shall be greater than a, so as to form a clearance fit with the outer peripheral rod 102 of this layer; the curvature radius of the arch portion 212 of the other guiding device 2 is set corresponding to b, and when the rotating seat 22 of said guiding device 2 slides to the side away from the linear driving member 24, the diameter of the inscribed circle formed by the arch portion 212 and the rotating seat 22 shall be greater than b, so as to form a clearance fit with the outer peripheral rod 102 of this layer.

[0056] Specifically, the manufacturing method corresponding to this embodiment shall include:

[0057] All the guiding devices 2 are fully opened; that is, the rotating seat 22 of the guiding device 2 slides to the side close to the linear driving member 24, and the two clamping arms 21 are spaced apart from each other;

[0058] The guiding devices 2 are sequentially closed and opened in the order of the curvature radius of the arch portions 212 thereon from small to large, to assemble the outer peripheral rods 102 of the corresponding layers.

[0059] As an optional embodiment, the guiding device 2 further includes a return spring 27, which is disposed at the connection between the hinge portion 211 and the rotating seat 22, and the return spring 27 is configured to keep the two clamping arms 21 spaced apart from each other. After the outer peripheral rods 102 are installed, the linear driving member 24 retracts to the side away from the rotating seat 22. Due to the action of the return spring 27, the two clamping arms 21 will move away from each other first, and then the rotating seat 22 will descend along the sliding rail 25, which is beneficial to avoiding scratching or damaging the water-conducting blind pipe 100 when the guiding device 2 exits. Preferably, there is a frictional force between the rotating seat 22 and the sliding rail 25 that is not less than the self-weight of the rotating seat 22, so that the guiding device 2 is fully opened before exiting. Specifically, a friction plate may be disposed between the rotating seat 22 and the sliding rail 25, and an adjusting screw abutting against the friction plate may be disposed on the rotating seat 22 along the width direction of the sliding rail 25 to adjust the frictional force between the rotating seat 22 and the sliding rail 25.

[0060] As an optional embodiment, an open-type strapper 3 is further included, the open-type strapper 3 is disposed between the two chucks 11, and the feeding port of the open-type strapper 3 is disposed corresponding to the gap between the two end portions 213. When the outer peripheral rods 102 are placed into the guiding device 2, the feeding port of the open-type strapper 3 can avoid the path of the outer peripheral rods 102, which is beneficial to simplifying the operation difficulty of assembling the water-conducting blind pipe 100.

[0061] As an optional implementation, a guide rail 4 is also included, which is arranged along the line connecting the two chucks 11, and the open-type strapping device 3 is slidably disposed on the guide rail 4. The open-type strapping device 3 can slide along the axial direction of the water-conducting blind pipe 100 via the guide rail 4, so that a single open-type strapping device 3 can also perform multiple strapping along the axial direction on the water-conducting blind pipe 100, which helps to reduce the complexity and cost of manufacturing equipment.

[0062] In addition, the clamping device can also be slidably mounted on the guide rail 4 so that the clamping device can match the center rod 101 of different lengths. Specifically, the clamping device may also include a mounting base, with the chuck 11 rotatably connected to the mounting base, and the mounting base slidably connected to the guide rail 4.

[0063] Example 3

[0064] This embodiment provides a method for manufacturing a blind drainage pipe for saline-alkali land improvement, applied to the manufacturing equipment in any of the above embodiments, including the following steps:

[0065] S1: Install both ends of the central rod 101 onto the two chucks 11 respectively;

[0066] S2: Insert the outer peripheral rods 102 into the space through the gap between the two ends 213 in sequence, and arrange the outer peripheral rods 102 so that they are arranged circumferentially along the inner wall of the space;

[0067] S3: Bind the outer peripheral member 102;

[0068] S4: Cover the outer perimeter of the outer rod 102 with straw mats and bamboo mats, and secure them.

[0069] As an optional implementation, step S2 includes:

[0070] S21: Insert the outer peripheral rod 102 into the space through the gap between the two ends 213, and place the bamboo pole at the bottom of the space;

[0071] S22: Continue to insert the outer peripheral rod 102 into the space through the gap between the two ends 213. This will cause the subsequently inserted outer peripheral rod 102 to push the previously inserted outer peripheral rod 102 toward a clamping arm 21 until the space is filled.

[0072] As an optional implementation, the clamping device also includes a rotating shaft, which is rotatably connected to the chuck 11; step S4 includes: rotating the rotating shaft to rotate the central rod 101 and the outer peripheral rod 102; and winding and fixing the straw mat and bamboo mat around the outer peripheral rod 102.

[0073] Example 4

[0074] A blind water conduit 100 for saline-alkali land improvement is manufactured using the equipment described in Example 1 or 2, and / or by the method described in Example 3, and includes a central rod, an outer peripheral rod surrounding the central rod, and a covering layer 103 surrounding the outer peripheral rod.

[0075] The central member is a water guide rod 101, and the outer peripheral members include multiple water guide rods 101 arranged around the central member and at least one connecting rod 102 arranged parallel to the central member.

[0076] The water guide rod 101 has multiple spaced partitions 1011 arranged axially inside, forming a space between adjacent partitions 1011. The partitions 1011 have through holes 10111 to connect the adjacent spaces. The wall of the water guide rod 101 has water-permeable holes 1012 that penetrate the space to the outside of the water guide rod 101. There are multiple water guide rods 101, which are connected to each other radially. The end of the connecting rod 102 has a connecting structure 1021. The connecting rod 102 is arranged parallel to the water guide rod 101 and radially connected to the water guide rod 101, so that the multiple water guide rods 101 and the connecting rod 102 form an outer peripheral rod 102 arranged in a bundle structure. The covering layer 103 includes a water storage layer 1031, which wraps around the outer peripheral rod.

[0077] When in use, the blind drainage pipe 100 is laid below the ground surface, with one end connected to an open drainage ditch. When there is excess moisture in the surface soil, some of the moisture is absorbed and stored by the water storage layer 1031, while the other part of the water enters the interior of the water guide rod 101 through the permeable hole 1012 and flows into the open drainage ditch through the connecting hole 10111. Due to the presence of the baffle 1011, not all the water will be discharged from the water guide rod 101, but some will be retained by the baffle 1011. When the residual moisture in the surface soil evaporates rapidly, the water retained in the water storage layer 1031 and the water guide rod 101 will replenish the surface soil, replacing the evaporation of groundwater, thereby reducing the movement of groundwater carrying salt to the surface soil and thus achieving the purpose of preventing the rise of soil salinity.

[0078] The covering layer 103 wraps around the outer periphery of the outer peripheral rod. By setting the central rod and the outer peripheral rod, all the blind water pipes 100 can have similar structures, which facilitates the connection between different blind water pipes 100.

[0079] The central member can be a single water guide rod 101, or it can be formed by radially binding 2-4 water guide rods 101.

[0080] Preferably, the water guide rod 101 is made of bamboo. Bamboo has naturally formed hollow nodes, with natural diaphragms between the nodes acting as partitions 1011. Bamboo is a natural renewable resource; compared to traditional plastic or metal blind pipes, bamboo has a shorter growth cycle and causes less environmental damage. Using bamboo water guide pipes 100 in the process of saline-alkali land reclamation aligns with green environmental protection principles, helps reduce dependence on non-renewable resources, and achieves sustainable development.

[0081] As an optional implementation, the outer peripheral members are arranged in multiple layers, nested sequentially. A filter layer 1032 or a filter layer 1032 and a water storage layer 1031 are provided between adjacent outer peripheral members. A covering layer 103 wraps around the outermost outer peripheral member. Setting multiple layers of outer peripheral members allows for more guide rods 101 and water storage layers 1031 within the same blind water pipe 100, which helps increase the drainage efficiency and water storage capacity of the blind water pipe 100.

[0082] It should be noted that when using bamboo poles to manufacture the water guide pole 101, pre-drying and anti-corrosion treatments should be performed. For example, drying can be done naturally for 1-2 weeks, or by drying at 60-80℃ for 2-3 hours, reducing the moisture content of the bamboo poles to 10%-15%. Anti-corrosion treatment can be done using traditional fumigation methods or modern chemical impregnation methods (such as soaking in preservatives like boric acid solution) to extend service life. The bamboo poles can be soaked in the preservative for 24-48 hours. After soaking, remove the bamboo poles and let them air dry to allow the preservative to fully penetrate the interior of the bamboo. If necessary, tung oil or varnish can also be applied to the surface of the bamboo.

[0083] The outer side of the cover layer 103 and / or the outer side of the bundle structure formed by the water guide rod 101 and the connecting rod 102 can be fixed with wire, rope or cable tie.

[0084] When laying the blind water conduit 100, the trench should be excavated using excavation equipment or manually. The width and depth of the trench should be determined according to the dimensions of the blind water conduit 100. Generally, the trench width should be 10-15 cm larger than the diameter of the blind water conduit 100, and the trench depth should be between 30-50 cm. During excavation, care should be taken to maintain the verticality and flatness of the trench walls to avoid collapse.

[0085] As an optional implementation, one end of the connecting rod 102 is provided with a tapered pin 10211, and the other end is provided with a pin hole 10212. The tapered pin 10211 is used to cooperate with the pin hole 10212 of another connecting rod 102. The two connecting rods 102 can be connected by the cooperation of the tapered pin 10211 and the pin hole 10212, which helps to improve the convenience of construction when laying the water-conducting blind pipes 100.

[0086] The connecting rod 102 can be made of bamboo with a diameter smaller than that of the water guide rod 101.

[0087] As an optional implementation, the length of the tapered pin 10211 is greater than or equal to 20 cm.

[0088] As an optional implementation, the cover layer 103 further includes a filter layer 1032, which wraps around the outer periphery of the water storage layer 1031. The filter layer 1032 can prevent impurities such as silt from entering the water guide rod 101 and causing blockage.

[0089] As an optional implementation, the water storage layer 1031 is made of straw mat, and the filter layer 1032 is made of bamboo mat. Using straw mat as the water storage layer 1031 and bamboo mat as the covering layer 103 helps reduce the generation of microplastics during the use of the blind water conduit 100, and helps improve the environmental performance of the blind water conduit 100 during use.

[0090] As an optional implementation, the permeable holes 1012 on the multiple water guide rods 101 face the same direction. When laying the blind water guide pipe 100, the permeable holes 1012 are oriented vertically upwards, so that most of the water entering the water guide rod 101 returns to the soil in the form of evaporation along the permeable holes 1012 rather than being directly lost.

[0091] As an optional implementation, the wall thickness of the water guide rod 101 is greater than or equal to 8 mm.
