Description

Technical Field

[0001] The present invention relates to the technical field of agricultural irrigation, and particularly to a high-speed production equipment for intelligent buried drip irrigation pipes. Background Art

[0002] At present, agriculture is gradually becoming intelligent. First of all, it requires the integration of water and fertilizer. In the past 30 years, China has achieved great success in water and fertilizer conservation by using micro-irrigation. Now, higher requirements have been put forward for agricultural development. Because the utilization rate of surface irrigation of water and fertilizer is low, the service life of the materials used for irrigation is short, and repeated laying and replacement waste resources and working time. To solve this problem, the buried drip irrigation method can be adopted at present. As another water-saving irrigation technology after sprinkler irrigation and drip irrigation, the drip irrigation technology essentially belongs to a form of underground irrigation. The drip irrigation pipe is pre-laid in the soil of the crop root activity layer, and the irrigation water source is directly sent to the crop root soil through the pipeline. With the help of the capillary water absorption and water potential of the soil, the water slowly and evenly enters the plant root area, which can solve problems such as surface water evaporation and soil erosion caused by spraying in ordinary irrigation technology, and can also loosen the soil, reduce pollution, and promote crop growth. It is a new water-saving irrigation technology with low cost, high income, and green and low-carbon.

[0003] A water-saving composite drip irrigation pipe and its preparation method disclosed in the existing publication (announcement) number: CN114868625A. The water-saving composite drip irrigation pipe includes a drip irrigation matrix layer and a drip irrigation film layer on its outer side. A plurality of mutually connected capillary pores are distributed in the drip irrigation matrix layer. The capillary pores extend from the inside of the drip irrigation matrix layer to the surface of the drip irrigation matrix layer and communicate with the outside. The drip irrigation film layer is formed by compounding a water-conducting fiber with a film matrix. Both ends of the water-conducting fiber are respectively exposed on both sides of the film matrix. The water-conducting fiber includes a fiber filament and a polyacrylamide-montmorillonite composite water-conducting material coated on the surface of the fiber filament. There are a plurality of mutually connected capillary pores in the drip irrigation matrix layer. When the drip irrigation matrix layer is filled with water as the inner layer of the pipeline, the water seeps from the inside of the drip irrigation matrix layer to the outside of the drip irrigation matrix layer along the capillary pores by capillary action and reaches the drip irrigation film layer. The existing composite drip irrigation pipes (such as CN114868625A) need to be prepared by multi-layer compounding, embedding of water-conducting fibers and post-curing processes. The production time of a single pipe is about 8-10 minutes, while a typical buried irrigation project requires 50,000-100,000 meters of pipes, resulting in a total production cycle of more than 2,000 hours. In contrast, the present invention improves the single-pipe production speed to 2 m / min through integrated extrusion, synchronous hole punching at high temperature and hierarchical cooling design, increases the efficiency by 15 times, and the rejection rate is less than 0.5%. Summary of the Invention

[0004] (I) Technical Problems to be Solved

[0005] In view of the above-mentioned disadvantages and deficiencies of the prior art, the present invention provides an intelligent buried drip irrigation pipe high-speed production equipment, which solves the technical problems of complex preparation process and low production efficiency of drip irrigation pipes.

[0006] (II) Technical Solution

[0007] In order to achieve the above object, the main technical solutions adopted by the present invention include:

[0008] The embodiment of the present invention provides an intelligent buried drip irrigation pipe high-speed production equipment, which sequentially includes a pipe extrusion mechanism, a hole forming mechanism, a cooling and forming mechanism, a forward traction mechanism, and a coiling and winding mechanism according to the production sequence. The pipe extrusion mechanism includes a feeding bin, a screw melting zone, and an extrusion forming zone. The extrusion forming zone includes an extrusion die head and an extrusion die sleeve arranged at the discharge end of the screw melting zone. An annular cavity for the molten raw material to pass through and form is formed between the extrusion die head and the extrusion die sleeve. The hole forming mechanism is located at the discharge end of the annular cavity and uniformly punches the formed pipe wall. The cooling and forming mechanism includes a cooling pool for continuously immersing the formed pipe for cooling. The forward traction mechanism includes multiple groups of forward wheels for clamping and horizontally moving the formed pipe. Each group of forward wheels includes two upper and lower ones, and a clamping groove for clamping and moving the formed pipe is formed on the circumferential side end of the forward wheel.

[0009] For an intelligent buried drip irrigation pipe high-speed production equipment proposed in the embodiment of the present invention, when producing buried drip irrigation pipes through this production equipment, the raw materials are directly poured into the feeding bin, and then the raw materials will enter the screw melting zone for melting and be transported to the extrusion forming zone. The molten raw material passes through the annular cavity between the extrusion die head and the extrusion die sleeve, thereby forming a continuous tube. At this time, the formed pipe has a high temperature and its shape is not completely fixed. Subsequently, the formed pipe is pulled out of the extrusion forming zone and timely punched through the hole forming mechanism. The punched formed pipe is directly immersed in the cooling pool for cooling and complete shaping. The formed pipe is clamped and pulled by multiple groups of forward wheels of the forward traction mechanism, so as to ensure the continuous production of subsequent formed pipes, and finally be wound on the coiling and winding mechanism. This solution makes the production of buried drip irrigation pipes more continuous and faster. At the same time, punching is carried out when the drip irrigation pipe is formed and has a high temperature, which is more convenient.

[0010] Optionally, the hole forming mechanism includes an extension rod coaxially fixed to one end of the extrusion die head away from the screw melting zone, a punching ring coaxially arranged at one end of the extension rod away from the extrusion die head, and multiple rotating rings rotatably connected to the punching ring. The rotation axis of the rotating ring is perpendicular to the rotation axis of the punching ring, and punching needles for punching through the formed pipe from the inside to the outside are vertically and circumferentially uniformly spaced on the circumferential side end of the rotating ring.

[0011] After the formed pipe is extruded from the annular cavity, the formed pipe extends along the extension rod. When the formed pipe extends and passes through the hole-punching ring, the punching needles on the rotating ring penetrate into the inner wall of the formed pipe and penetrate to the outer wall of the formed pipe. At the same time, as the formed pipe continues to pass through, the rotating ring will rotate and continuously punch holes, and multiple rotating rings will punch holes evenly arrayed on the formed pipe to achieve more dense punching holes, so that the buried irrigation pipe seeps water more finely and evenly during use. At the same time, the punching needles punch holes from the inside to the outside, making the punched holes gradually narrow from the inside to the outside, which is more convenient to adjust the water seepage effect by changing the water pressure later and reduces the probability of blockage.

[0012] Optionally, a plurality of the hole-punching rings are provided and arranged at intervals coaxially. Four of the rotating rings are circumferentially and evenly spaced on each of the hole-punching rings, and the rotation axes of the rotating rings on different hole-punching rings are skew lines.

[0013] By providing a plurality of hole-punching rings and rotatably connecting four rotating rings on each hole-punching ring, the rotation axes of the rotating rings on different hole-punching rings are skew lines, that is, all the rotating rings on the four hole-punching rings just cover the entire inner wall of the formed pipe, making the punching holes finer while avoiding a large pulling force at the same cross-section and reducing the impact on the continuous production of the formed pipe, which is more convenient.

[0014] Optionally, the hole-forming mechanism further includes a push sleeve fixed to one end of the extrusion die sleeve and a plurality of groups of outer push components circumferentially and evenly distributed on the inner wall of the push sleeve and located on the outer peripheral side of the extension rod. The outer push component includes a push frame rotatably connected to the inner wall of the push sleeve through a torsion spring and a push wheel rotatably connected to the push frame driven by a motor. An annular groove with an arc-shaped cross-section is formed at the circumferential end of the push wheel. The push frame drives the push wheel to abut against the side end of the formed pipe under the drive of the torsion spring, and the push wheel applies an outward pulling thrust to the formed pipe.

[0015] The hole-forming mechanism will cause a certain obstruction during hole punching. When the formed pipe is simply pulled out by the forward pulling mechanism, it is easy to cause the uncooled formed pipe to be stretched or broken. In this solution, by providing a plurality of groups of outer push components, the push wheel abuts against the side end of the formed pipe under the drive of the push frame, and the motor drives the push wheel to rotate, so as to apply a certain outward extending force to the formed pipe. Together with the forward pulling mechanism, the formed pipe with holes can be pulled out more smoothly, which is more convenient.

[0016] Optionally, the coiling and winding mechanism includes a support frame and a winding frame rotatably connected to the side end of the support frame. The rotation axis of the winding frame is horizontal. A gas injection plug for fixing and communicating with the end of the formed pipe is provided on the winding frame. The formed pipe is wound around the side end of the winding frame as the winding frame rotates, and the gas injection plug continuously injects gas into the formed pipe during the winding process of the formed pipe.

[0017] By arranging an air injection plug on the take-up rack, one end of the forming pipe is connected and communicated with the air injection plug. As the take-up rack rotates and winds, the air injection plug continuously injects air into the forming pipe, and the air will run out through the holes punched on the forming pipe, thus ensuring the continuous smoothness of the holes punched on the forming pipe. At the same time, it can prevent water from entering the inside of the forming pipe when the forming pipe is cooled and formed, which is more convenient.

[0018] Optionally, a lifting frame is vertically slidably arranged at the side end of the support frame. A rotating sleeve is rotatably arranged in the middle of the lifting frame. A jack for horizontally inserting and fixing the rotating sleeve is opened in the middle of the take-up rack. A slot is opened in the middle of the rotating sleeve, and an air pump is inserted into the slot. The air outlet end of the air pump is communicated with the air injection plug, and a clamping groove for inserting and fixing the air injection plug is opened on the take-up rack.

[0019] By vertically slidably arranging a lifting frame at the side end of the support frame and arranging a rotating sleeve on the lifting frame, after the take-up rack winds one roll of the buried drip irrigation pipe, it can be directly disassembled from the rotating sleeve, and then a new take-up rack is installed, so as to realize the continuous production of the buried drip irrigation pipe, which is more convenient. At the same time, the air pump is installed in the middle of the rotating sleeve, and the air injection plug is also detachably connected to the take-up rack, making the subsequent connection more convenient.

[0020] Optionally, the forward guiding and traction mechanism further includes a traction machine frame. The forward guiding wheel is rotatably connected to the traction machine frame. A grinding sleeve is horizontally arranged between two adjacent groups of the forward guiding wheels on the traction machine frame. The grinding sleeve is coaxially symmetric with the clamping groove, and grinding bumps for grinding the outer wall of the forming pipe are uniformly arranged in an array on the inner wall of the grinding sleeve.

[0021] When punching holes on the forming pipe from the inside to the outside by a needle, tiny burrs will be formed on the outer surface of the buried drip irrigation pipe, making it easy to block the punched holes when winding the buried drip irrigation pipe. In this solution, by arranging a grinding sleeve between two adjacent groups of the forward guiding wheels, when the buried drip irrigation pipe passes through the grinding sleeve, the grinding bumps on the inner wall of the grinding sleeve will grind off the burrs. At the same time, the internal air pressure of the buried drip irrigation pipe will prevent the grinding debris from blocking the punched holes, which is more convenient.

[0022] Optionally, smooth chamfers are arranged at the openings at both ends of the grinding sleeve.

[0023] By arranging smooth chamfers at the openings at both ends of the grinding sleeve, when the buried drip irrigation pipe passes through the grinding sleeve, it will not be affected by other forces except the friction generated during internal grinding, so that it can pass more smoothly, which is more convenient.

[0024] Optionally, the cooling and forming mechanism further includes a plurality of flowing water flushing pipes disposed at a side end of the cooling pool and extending above the cooling pool, and the plurality of flowing water flushing pipes are aligned with the discharging end of the extrusion forming area.

[0025] By arranging the flowing water flushing pipes above the cooling pool, aligning the cold water flushing pipes with the formed pipe drawn out from the extrusion forming area and spraying water, the cooling and forming of the formed pipe can be accelerated, the length of the cooling pool can be reduced, and further the volume of the entire production equipment can be reduced.

[0026] Optionally, the extrusion die head and the extrusion die sleeve are detachably connected to the discharging end of the screw melting area.

[0027] By detachably connecting the extrusion die head and the extrusion die sleeve to the discharging end of the screw melting area, the extrusion die head and the extrusion die sleeve can be replaced as needed, so as to produce buried irrigation pipes with different outer diameters and inner diameters. At the same time, the hole forming mechanism can be replaced synchronously to adapt to buried irrigation pipes with different diameters, which is more convenient.

[0028] (III) Beneficial effects

[0029] The beneficial effects of the present invention are as follows: for the intelligent high-speed production equipment for buried irrigation pipes of the present invention, when producing buried irrigation pipes through this production equipment, the raw materials are directly poured into the feeding bin, and then the raw materials will enter the screw melting area for melting and be transported to the extrusion forming area. The molten raw materials pass through the annular cavity between the extrusion die head and the extrusion die sleeve, so as to form a continuous tube. At this time, the temperature of the formed tube is relatively high and its shape is not completely fixed. Then, the formed tube is drawn out of the extrusion forming area and timely punched through the hole forming mechanism. The formed tube after punching is directly immersed in the cooling pool for cooling and complete shaping, and the formed tube is clamped and pulled by multiple sets of outgoing wheels of the outgoing traction mechanism, so as to ensure the continuous production of the subsequent formed tubes, and finally be wound on the coiling and winding mechanism. This solution makes the production of buried irrigation pipes more continuous and faster, and at the same time, punching is carried out when the irrigation pipe is formed and the temperature is relatively high, which is more convenient.

[0037] In order to better explain the present invention for easy understanding, the present invention will be described in detail below with reference to the accompanying drawings through specific implementation manners.

[0038] For the intelligent buried drip irrigation pipe high-speed production equipment proposed in the embodiment of the present invention, when producing buried drip irrigation pipes through this production equipment, the raw materials are directly poured into the feeding bin, and then the raw materials will enter the screw melting zone for melting and be transported to the extrusion forming zone. The molten raw materials pass through the annular cavity between the extrusion die head and the extrusion die sleeve, thereby forming a continuous tube. At this time, the formed tube has a high temperature and its shape is not completely fixed. Then, the formed tube is pulled out of the extrusion forming zone and timely punched through the hole forming mechanism. The punched formed tube is directly immersed in the cooling pool for cooling and complete shaping. The formed tube is clamped and pulled by multiple forward guiding wheels of the forward pulling and guiding mechanism, so as to ensure the continuous production of the subsequent formed tube, and finally be wound around the coiling and winding mechanism. This solution makes the production of buried drip irrigation pipes more continuous and faster. At the same time, punching is carried out when the drip irrigation pipe is formed and has a high temperature, which is more convenient.

[0039] In order to better understand the above technical solution, the exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and the scope of the present invention can be completely conveyed to those skilled in the art.

[0040] Refer to Figure 1, An intelligent in-ground infiltration irrigation pipe high-speed production equipment, which sequentially includes a pipe extrusion mechanism 1, a hole-forming mechanism 2, a cooling and forming mechanism 3, a forward traction mechanism 4, and a coiling and winding mechanism 5 according to the production sequence.

[0041] See Figure 1 and Figure 2 , The pipe extrusion mechanism 1 includes a feeding bin 11, a screw melting zone 12, and an extrusion and forming zone 13. The extrusion and forming zone 13 includes an extrusion die head 131 and an extrusion die sleeve 132 arranged at the discharging end of the screw melting zone 12. A ring cavity 133 for the molten raw material to pass through and form is formed between the extrusion die head 131 and the extrusion die sleeve 132. The hole-forming mechanism 2 is located at the discharging end of the ring cavity 133 and uniformly punches holes in the formed pipe wall. The raw material is directly poured into the feeding bin 11, and then the raw material will enter the screw melting zone 12 for melting and be transported to the extrusion and forming zone 13. The molten raw material passes through the ring cavity 133 between the extrusion die head and the extrusion die sleeve 132, thus forming a continuous tube. At this time, the temperature of the formed tube is relatively high and its shape is not completely fixed. Then, the formed tube is pulled out of the extrusion and forming zone 13 and timely punched by the hole-forming mechanism 2.

[0042] See Figure 2 and Figure 3 , The hole-forming mechanism 2 includes an extension rod 21 coaxially fixed at one end of the extrusion die head 131 away from the screw melting zone 12, a hole-punching ring 22 coaxially arranged at one end of the extension rod 21 away from the extrusion die head 131, and a plurality of rotating rings 23 rotatably connected to the hole-punching ring 22. The rotation axis of the rotating ring 23 is perpendicular to the rotation axis of the hole-punching ring 22. A plurality of punching needles 24 that pierce the formed tube from the inside to the outside are vertically and circumferentially evenly spaced on the circumferential side of the rotating ring 23. Each rotating ring 23 is circumferentially evenly distributed with 12 punching needles 24. The diameter of the punching needle is 0.3 mm, the tip angle is 25°, and the material is SUS440C stainless steel (hardness HRC58 - 60); the punching needles are inclined at a radial inclination angle of 5°, so that the puncture holes are in the shape of a cone with a larger inner diameter and a smaller outer diameter (the inlet diameter is 0.3 mm, and the outlet diameter is 0.2 mm), reducing the risk of blockage. When the formed tube is extruded from the ring cavity 133, the formed tube extends along the extension rod 21. When the formed tube extends and passes through the hole-punching ring 22, the punching needles 24 on the rotating ring 23 pierce into the inner wall of the formed tube and penetrate to the outer wall of the formed tube. At the same time, as the formed tube continues to pass through, the rotating ring 23 will rotate and continuously punch holes, and the plurality of rotating rings 23 will uniformly array punch holes on the formed tube to achieve more dense punching holes, so that the in-ground infiltration irrigation pipe seeps water more finely and evenly during use. At the same time, the punching needles 24 punch holes from the inside to the outside, so that the puncture holes gradually narrow from the inside to the outside, which is more convenient to adjust the water seepage effect by changing the water pressure later and reduces the probability of blockage at the same time.

[0043] There are multiple punching rings 22 arranged coaxially at intervals, and four rotating rings 23 are circumferentially and evenly spaced on each punching ring 22. The rotation axes of the rotating rings 23 on different punching rings 22 are skew lines. By arranging multiple punching rings 22 and rotatably connecting four rotating rings 23 to each punching ring 22 respectively, the rotation axes of the rotating rings 23 on different punching rings 22 are skew lines, that is, all the rotating rings 23 on the four punching rings 22 just cover the entire inner wall of the formed pipe, making the punching finer while avoiding a large pulling force at the same cross-section and reducing the impact on the continuous production of the formed pipe.

[0044] The hole forming mechanism 2 further includes a push sleeve 25 fixed to one end of the extrusion die sleeve 132 and multiple groups of outer push components 26 circumferentially and evenly spaced on the inner wall of the push sleeve 25 and located on the outer peripheral side of the extension rod 21. The outer push component 26 includes a push frame 261 rotatably connected to the inner wall of the push sleeve 25 through a torsion spring and a push wheel 262 rotatably connected to the push frame 261 driven by a motor. An annular groove 2621 with an arc-shaped cross-section is formed on the circumferential side end of the push wheel 262. The push frame 261 drives the push wheel 262 to abut against the side end of the formed pipe under the drive of the torsion spring, and the push wheel 262 applies an outward pulling thrust to the formed pipe. By arranging multiple groups of outer push components 26, the push wheel 262 abuts against the side end of the formed pipe under the drive of the push frame 261, and the push wheel 262 is driven to rotate by the motor, so as to apply a certain force for the formed pipe to extend outward. Then, cooperating with the forward-out traction mechanism 4, the formed pipe with holes can be smoothly drawn out.

[0045] See Figure 1 , the cooling and forming mechanism 3 includes a cooling pool 31 for the formed pipe to continuously immerse in for cooling and multiple water flow flushing pipes 32 arranged at the side end of the cooling pool 31 and extending to the upper side of the cooling pool 31. The multiple water flow flushing pipes 32 are aligned with the discharging end of the extrusion forming area 13. By arranging the water flow flushing pipes 32 on the upper side of the cooling pool 31, the cold water flushing pipes are aligned with the formed pipe drawn out from the extrusion forming area 13 and sprayed with water, so as to accelerate the cooling and forming of the formed pipe, reduce the length of the cooling pool 31, and further reduce the volume of the entire production equipment.

[0046] See Figure 1 and Figure 4, the forward-out traction mechanism 4 includes a traction machine frame 41 and multiple groups of forward-out wheels 42 that are rotationally connected to the traction machine frame 41 by a motor drive and clamp and move the formed pipe horizontally. Each group of forward-out wheels 42 includes two, one above the other. A clamping groove 421 for the formed pipe to move is provided on the circumferential side end of the forward-out wheel 42. A grinding sleeve 43 is horizontally arranged between adjacent two groups of forward-out wheels 42 on the traction machine frame 41. The grinding sleeve 43 is coaxially symmetric with the clamping groove 421. Grinding bumps 431 for grinding the outer wall of the formed pipe are uniformly arranged in an array on the inner wall of the grinding sleeve 43. Smooth chamfers 432 are provided at both ends of the grinding sleeve 43 with openings. The formed pipe is clamped and pulled by multiple groups of forward-out wheels 42 of the forward-out traction mechanism 4, and the grinding sleeve 43 is arranged between adjacent two groups of forward-out wheels 42. When the buried irrigation pipe passes through the grinding sleeve 43, the grinding bumps 431 on the inner wall of the grinding sleeve 43 will grind off the burrs. At the same time, the internal air pressure of the buried irrigation pipe will prevent the grinding debris from blocking the punched holes.

[0047] See Figure 1 and Figure 5 , the coiling and winding mechanism 5 includes a support frame 51 and a winding frame 52 rotationally connected to the side end of the support frame 51. The rotation axis of the winding frame 52 is horizontal. An air-blowing plug 53 for fixing and connecting the end of the formed pipe is provided on the winding frame 52. The formed pipe rotates with the winding frame 52 and is wound on the side end of the winding frame 52. The air-blowing plug 53 continuously blows air into the formed pipe during the winding process of the formed pipe. One end of the formed pipe is connected and communicated with the air-blowing plug 53. As the winding frame 52 rotates and winds, the air-blowing plug 53 continuously blows air into the formed pipe, and the air will run out along the punched holes on the formed pipe, thereby ensuring the continuous smoothness of the punched holes on the formed pipe. At the same time, it can prevent water from entering the inside of the formed pipe when the formed pipe is cooled and formed, which is more convenient.

[0048] A lifting frame 54 is vertically slidably arranged at the side end of the support frame 51. A rotating sleeve 55 is rotatably arranged in the middle of the lifting frame 54. A socket 521 for the horizontal insertion and fixation of the rotating sleeve 55 is provided in the middle of the winding frame 52. A slot 551 is provided in the middle of the rotating sleeve 55. An air pump 552 is inserted into the slot 551. The air outlet end of the air pump 552 is communicated with the air-blowing plug 53. A clamping groove 522 for the insertion and fixation of the air-blowing plug 53 is provided on the winding frame 52. After the winding frame 52 winds one roll of the buried irrigation pipe, it can be directly disassembled from the rotating sleeve 55, and then a new winding frame 52 is installed, thereby realizing the continuous production of the buried irrigation pipe, which is more convenient. At the same time, the air pump 552 is installed in the middle of the rotating sleeve 55, and the air-blowing plug 53 is also detachably connected to the winding frame 52, making the subsequent connection more convenient.

[0049] See Figure 2 and Figure 3, the extrusion die head 131 and the extrusion die sleeve 132 are detachably connected to the discharge end of the screw melting zone 12, so that the extrusion die head 131 and the extrusion die sleeve 132 can be replaced as needed, thereby realizing the production of buried drip irrigation pipes with different outer diameters and inner diameters. At the same time, the hole forming mechanism 2 can be replaced synchronously to adapt to buried drip irrigation pipes with different diameters, which is more convenient.

[0050] The gap of the annular cavity 133 between the extrusion die head 131 and the extrusion die sleeve 132 is adjustable (0.5 - 3 mm), which is suitable for the production of pipes with a wall thickness of 0.3 - 2.0 mm; the die head and the die sleeve are coated with tungsten carbide (hardness ≥ HRA90), with a wear-resistant life of ≥ 1500 hours, and are connected to the screw melting zone 12 through a flange quick-release structure (not shown).
