Description

Technical Field

[0001] This invention relates to the field of pipeline laying construction equipment technology, specifically a special pipe laying equipment and method for concealed pipe salt drainage. Background Technology

[0002] The formation of alkaline and alkalized soils in my country is largely related to the accumulation of carbonates in the soil, resulting in generally high alkalinity. In severely saline-alkali soil areas, plants can hardly survive. Drainage and salt leaching are essential measures for saline-alkali land management, following the natural law that "salt comes with water and goes with water." Underground drainage technology involves laying porous pipes at a certain depth underground. Water collected after irrigation or rainfall, or groundwater directly flowing into the pipes, is discharged through the pipes, carrying away salt and thus improving the saline-alkali land.

[0003] Existing underground pipe laying equipment for salt drainage involves laying perforated corrugated pipes in trenches and covering them with soil. However, because the corrugated pipes are made of plastic, they are prone to bending and deformation during laying. If these bends or deformations are not detected when covering with soil, they can easily lead to pipe blockage later. If they are detected, manual straightening and adjustment are required, which not only affects work efficiency but also causes inconvenience to workers. Especially when covering with soil, if a large amount of soil is applied at once, the corrugated pipes are more likely to deform under the influence of soil gravity and impact. Furthermore, it is not easy for workers to find the deformed locations after covering with soil, making the operation quite inconvenient. Therefore, there is an urgent need to develop a dedicated underground pipe laying equipment and method for salt drainage to overcome the shortcomings in current practical applications. Summary of the Invention

[0004] The purpose of this invention is to provide a special pipe-laying device and method for concealed salt drainage, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0010] External traction equipment drives the V-shaped soil-pulling seat and support shell to move in the trench. The V-shaped soil-pulling seat and support shell drive the pipeline conveying component and pipeline positioning component to move respectively. While the moving pipeline conveying component lays the pipeline in the trench, the pipeline positioning component achieves the pre-positioning of the pipeline after laying by covering the sides and top of the laid pipeline with different amounts of soil.

[0025] The transmission wheel and the counting wheel are rotatably mounted inside the support housing, and both the transmission wheel and the counting wheel are fitted with rubber rings, which are connected by rolling.

[0026] A measuring display, which is fixedly mounted on the outer wall of the support housing and electrically connected to the counting wheel; and

[0027] The detection counting wheel is fixedly connected to the transmission wheel, and the detection counting wheel also passes through the detection groove and is slidably connected to the detection groove. The detection counting wheel is also evenly distributed with multiple anti-slip protrusions.

[0028] As a further aspect of the present invention, it also includes: a placement groove, wherein the placement groove is formed at the bottom end of the V-shaped soil-removing seat;

[0029] Anti-slip rollers, wherein there are multiple anti-slip rollers evenly distributed within the placement groove and rotatably connected to the inner wall of the placement groove; and

[0030] The scraper blades are multiple in number, and all of the scraper blades are fixedly installed in the placement groove and are installed in conjunction with the anti-slip rollers.

[0031] As a further aspect of the present invention: the pipe positioning assembly includes:

[0032] A soil diversion port, which is fixedly installed on the top of the soil distribution cylinder;

[0033] The side outlets are two in number, and the two side outlets are respectively fixedly installed on both sides of the bottom of the soil diversion cylinder;

[0034] A central drain outlet, which is fixedly connected to the soil diversion cylinder and located in the middle of the two side drain outlets;

[0035] A drive motor is fixedly mounted on the soil distribution cylinder, and a rotating sleeve is fixedly mounted on the output end of the drive motor, the rotating sleeve being rotatably mounted inside the soil distribution cylinder; and

[0036] Discharge control unit, which is connected to the soil diversion cylinder and the rotating sleeve respectively.

[0037] As a further aspect of the present invention: the displacement control unit includes:

[0038] Two soil-feeding rollers are provided, with each roller located on one side of the rotating sleeve and having a receiving groove.

[0039] The second soil-feeding roller is fixedly installed on the rotating sleeve and located in the middle of the two first soil-feeding rollers. The second soil-feeding roller is also provided with a second receiving groove, the volume of which is smaller than the volume of the first receiving groove.

[0040] The through holes are multiple, and the multiple through holes are respectively opened in the receiving groove two and the receiving groove one;

[0041] A blower, fixedly mounted on the soil distribution cylinder, with an air supply pipe fixedly installed at the blower's output end, the air supply pipe being sleeved within the rotating sleeve and fixedly connected to the inner wall of the soil distribution cylinder; and

[0042] An air diversion protrusion is located on the air supply pipe and is slidably connected to the inner wall of the rotating sleeve. The air supply pipe is also detachably connected to the through hole.

[0043] A method for laying concealed pipes for salt drainage, which uses the aforementioned concealed pipe laying equipment for salt drainage, includes the following steps:

[0044] Step 1: First, place the V-shaped soil-pulling seat in the trench after the trenching is completed, and pass the pipe to be laid through the guide tube and place it in the arc-shaped conveying trough. Then, fix the external traction equipment to the mounting base. Under the pulling action of the external traction equipment, the V-shaped soil-pulling seat and the support shell move forward in the trench, while the pipe is continuously conveyed into the trench.

[0045] Step 2: During the pipeline laying process in Step 1, start the drive motor. The drive motor drives the rotating sleeve to rotate and drives the soil delivery roller one and soil delivery roller two to rotate synchronously, so as to discharge the different amounts of soil stored in the receiving tank one and receiving tank two to the sides and top of the pipeline through the side outlet and the middle outlet respectively.

[0046] Step 3: In step 2, while the middle outlet discharges soil, it also flattens the soil covering the pipeline, thereby simultaneously limiting the pipeline in all directions.

[0047] Compared with the prior art, the beneficial effects of the present invention are:

[0048] During pipeline laying, the V-shaped soil-lifting seat is first placed in the pre-dug trench. External traction equipment pulls the mounting base, moving the entire system within the trench. The V-shaped soil-lifting seat moves the soil at the bottom of the trench to both sides (this laterally moved soil can further restrict the laying of the pipeline), facilitating the pipeline's placement at the bottom and preventing bending or damage due to hard soil clods. Simultaneously, the pipeline conveying assembly continuously transports the pipeline to be laid behind the V-shaped soil-lifting seat and places it at the bottom of the trench. A soil distribution cylinder, pre-filled with relatively dry soil and equipped with auxiliary supports and rollers, positions the rollers on both sides of the trench. The soil is rolled on the surface to prevent excessive weight of the soil in the soil distribution cylinder from affecting the movement of the V-shaped soil-lifting seat in the trench. Of course, other methods can also be used, as long as the V-shaped soil-lifting seat can move smoothly in the trench. This will not be elaborated on further. After the pipeline is laid in the trench, under the control of the pipeline positioning component, the soil in the soil distribution cylinder can be discharged to the sides and top of the pipeline in different quantities according to the conditions on both sides and above the pipeline. That is, the amount of soil discharged from the sides of the pipeline is larger, and the discharge time of the soil above the pipeline lags behind that of the soil on the sides, ensuring that the pipeline is limited in all directions. The operation is simple, avoiding deformation of the pipeline under the influence of the gravity and impact of covering a large amount of soil at once. This ensures that the pipeline will not bend or deform during the laying process and avoids blockage during later use, improving work efficiency and providing convenience for workers.

Detailed Implementation

[0059] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0060] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0061] Please see 1- Figure 9The present invention provides a special pipe-laying device for concealed salt drainage, comprising a support plate 1, on which a mounting base 2 is fixedly installed, and further comprising:

[0062] A supporting housing 12 is fixedly connected to the supporting plate 1, and a V-shaped soil-diverting seat 10 is fixedly installed at the bottom end of the supporting housing 12. A bracket 13 is fixedly installed on the V-shaped soil-diverting seat 10, and a soil diversion cylinder 14 is fixedly installed on the bracket 13; and

[0063] A salt drainage pipe laying mechanism is connected to the support shell 12 and the soil diversion cylinder 14 respectively. The salt drainage pipe laying mechanism includes a pipe conveying component and a pipe positioning component.

[0064] The pipeline conveying assembly is connected to the supporting housing 12, the pipeline positioning assembly is connected to the soil diversion cylinder 14, and the pipeline positioning assembly is also located above the pipeline conveying assembly;

[0065] External traction equipment drives the V-shaped soil-pulling seat 10 and the support shell 12 to move in the trench. The V-shaped soil-pulling seat 10 and the support shell 12 drive the pipeline conveying component and the pipeline positioning component to move respectively. While the moving pipeline conveying component lays the pipeline in the trench, the pipeline positioning component achieves the pre-positioning of the pipeline after laying by covering the sides and top of the laid pipeline with different amounts of soil.

[0066] During pipeline laying, the V-shaped soil-pulling seat 10 is first placed in the prepared trench. The mounting base 2 is then pulled by an external traction device, moving the entire assembly within the trench. The V-shaped soil-pulling seat 10 causes the soil at the bottom of the trench to move to both sides (this soil movement can later limit the movement of the laid pipeline), facilitating the pipeline's placement at the bottom of the trench and preventing bending or damage due to hard soil clods at the bottom. Simultaneously, the pipeline conveying assembly continuously transports the pipeline to be laid to the rear of the V-shaped soil-pulling seat 10 and places it at the bottom of the trench. A soil diversion cylinder 14, pre-filled with relatively dry soil, is also installed. An auxiliary support rod 17, on which rollers are mounted, allows the rollers to... The soil is rolled on the ground on both sides of the trench to prevent the soil in the soil diversion cylinder 14 from being too heavy and affecting the movement of the V-shaped soil-lifting seat 10 in the trench. Of course, other methods can also be used, as long as the V-shaped soil-lifting seat 10 can move smoothly in the trench. We will not go into too much detail here. After the pipeline is laid in the trench, under the control of the pipeline positioning component, the soil in the soil diversion cylinder 14 can be discharged to the sides and top of the pipeline in different discharge amounts according to the situation on both sides and above the pipeline after the pipeline is laid. That is, the amount of soil discharged on both sides of the pipeline is larger, and the discharge time of the soil above the pipeline is delayed after the discharge time of the soil on both sides of the pipeline, so as to ensure that the pipeline is limited in all directions. The operation is simple and avoids the deformation of the pipeline under the influence of the gravity and impact of covering a large amount of soil at one time. This ensures that the pipeline will not bend or deform during the laying process and can avoid blockage during the later use of the pipeline, improving work efficiency and providing convenience for workers.

[0067] In one embodiment of the present invention, please refer to Figures 1-5 It also includes: a guide cylinder 3, which is fixedly installed on one side wall of the support plate 1;

[0068] An arc-shaped limiting plate 4 is fixedly installed on the other side wall of the support plate 1 and is positioned opposite the guide cylinder 3. The arc-shaped limiting plate 4 is also installed in conjunction with the pipeline conveying assembly.

[0069] The connecting rod 19 has its two ends fixedly connected to the V-shaped soil-moving seat 10 and the bracket 13, respectively.

[0070] Please see Figures 1-5 It also includes: a detection plate 20, which is fixedly installed at the end of the support housing 12 and located above the support housing 12; and

[0071] The plate 21 is provided in two pieces, and the two plates 21 are fixedly installed on both sides of the detection plate 20.

[0072] Please see Figures 1-5 It also includes: support plate 29, the number of support plates 29 is two, one end of each of the two support plates 29 is fixedly connected to the V-shaped soil-moving seat 10, and the two support plates 29 are arranged collinearly.

[0073] Two sets of telescopic cylinders 30 are provided, and the two sets of telescopic cylinders 30 are respectively fixedly installed on the two sets of support plates 29; and

[0074] An arc-shaped guide rod 31 is provided, with its two ends fixedly connected to the output ends of two sets of telescopic cylinders 30, and multiple rotating rings 32 are also fitted on the arc-shaped guide rod 31, with the rotating rings 32 rotatably connected to each other.

[0075] Guided by the guide cylinder 3 and the arc-shaped limiting plate 4, the pipeline can smoothly enter the pipeline conveying assembly. By working in conjunction with the arc-shaped guide rod 31 and the rotating ring 32, the pipeline can be smoothly laid at the bottom of the trench. The height of the arc-shaped guide rod 31 can be adjusted by the telescopic cylinder 30 to avoid excessive compression of the pipeline. When the V-shaped soil-removing seat 10 moves forward in the trench, the detection plate 20 can detect the degree of soil accumulation in front of the trench. When the soil accumulation is too high, it is not conducive to the laying of the pipeline, and the staff needs to be reminded to deal with it in time.

[0076] In one embodiment of the present invention, please refer to Figures 1-6 The pipeline delivery assembly includes:

[0077] Arc-shaped conveying trough 5, which is located on the supporting housing 12;

[0078] Two limiting baffles 7 are provided, and both limiting baffles 7 are fixedly installed on the supporting housing 12 and located on both sides of the arc-shaped conveying groove 5, respectively.

[0079] Reinforced protective plates 9, wherein there are multiple reinforced protective plates 9, and both ends of the multiple reinforced protective plates 9 are respectively fixedly connected to two limiting baffles 7; and

[0080] The laying plate 18 is fixedly connected to the V-shaped soil-moving seat 10 and is installed in conjunction with the arc-shaped conveying trough 5.

[0081] Please see Figures 1-6It also includes: a detection groove 6, which is formed on the support housing 12 and located in the middle of the arc-shaped conveying groove 5, wherein the diameter of the detection groove 6 is smaller than the diameter of the arc-shaped conveying groove 5 and is connected to the arc-shaped conveying groove 5;

[0082] The transmission wheel 34 and the counting wheel 35 are rotatably mounted inside the support housing 12, and each of the transmission wheel 34 and the counting wheel 35 is fitted with a rubber ring 36, and the two rubber rings 36 are rolled together.

[0083] A measuring display 25 is fixedly mounted on the outer wall of the support housing 12 and electrically connected to the counting wheel 35; and

[0084] The detection counting wheel 8 is fixedly connected to the transmission wheel 34, and the detection counting wheel 8 also passes through the detection groove 6 and is slidably connected to the detection groove 6. The detection counting wheel 8 is also evenly distributed with a plurality of anti-slip protrusions 33.

[0085] Under the guidance of the arc-shaped conveying trough 5, the limiting baffle 7, the reinforcing protective plate 9, and the laying plate 18, the external pipeline can be smoothly conveyed to the bottom of the trench. During the pipeline conveying process, since the pipeline is always located within the arc-shaped conveying trough 5 and moves within it, the detection counting wheel 8 can be driven to rotate. When the detection counting wheel 8 rotates, it can drive the counting wheel 35 to rotate via the transmission wheel 34, thereby detecting the length of the pipeline and displaying the detection data on the measuring display 25 for easy viewing by the staff. If the length on the measuring display 25 does not change during the conveying process, it indicates that the transmission wheel 34 and the counting wheel 35 are in a stopped state. At this time, the pipeline located in the arc-shaped conveying trough 5 may not be in contact with the detection counting wheel 8, indicating that the pipeline may have shifted position or experienced other issues during the conveying process. This allows the staff to check in time and avoid the pipeline bending or breaking due to squeezing or other issues during the conveying process. In addition, the support housing 12 is also equipped with an inspection cover 11, which allows for the inspection and maintenance of various components inside the support housing 12.

[0086] In one embodiment of the present invention, please refer to Figures 1-5 It also includes: a placement groove 26, which is located at the bottom end of the V-shaped soil-removing seat 10;

[0087] Anti-slip rollers 27, wherein there are multiple anti-slip rollers 27, which are evenly distributed within the placement groove 26 and rotatably connected to the inner wall of the placement groove 26; and

[0088] The scraper blade 28 is provided in multiples. All scraper blades 28 are fixedly installed in the placement groove 26 and are installed in conjunction with the anti-slip roller 27.

[0089] As the V-shaped soil-removing seat 10 moves within the trench, multiple anti-slip rollers 27 are installed to reduce friction between the V-shaped soil-removing seat 10 and the bottom of the trench. Each anti-slip roller 27 protrudes slightly from the bottom of the V-shaped soil-removing seat 10, allowing it to roll at the bottom of the trench. Simultaneously, a scraper 28 is installed to scrape away the soil adhering to the anti-slip rollers 27.

[0090] Please see Figures 1-9 The pipe positioning assembly includes:

[0091] Soil diversion port 16, which is fixedly installed on the top of the soil diversion cylinder 14;

[0092] Side outlet 22, the number of side outlets 22 is two, and the two side outlets 22 are respectively fixedly installed on both sides of the bottom of the soil diversion cylinder 14;

[0093] The central outlet 24 is fixedly connected to the soil diversion cylinder 14 and is located in the middle of the two side outlets 22;

[0094] A drive motor 15 is fixedly mounted on the soil distribution cylinder 14, and a rotating sleeve 42 is fixedly mounted on the output end of the drive motor 15. The rotating sleeve 42 is rotatably mounted inside the soil distribution cylinder 14.

[0095] The discharge control unit is connected to the soil diversion cylinder 14 and the rotating sleeve 42 respectively.

[0096] Please see Figures 1-9 The displacement control unit includes:

[0097] There are two soil feeding rollers 38, which are located on both sides of the rotating sleeve 42, and each of the two soil feeding rollers 38 has a receiving groove 45.

[0098] The second soil-feeding roller 39 is fixedly installed on the rotating sleeve 42 and located in the middle of the two first soil-feeding rollers 38. The second soil-feeding roller 39 is also provided with a second receiving groove 37, the volume of which is smaller than the volume of the first receiving groove 45.

[0099] Through holes 40, there are multiple through holes 40, and the multiple through holes 40 are respectively opened in the second receiving groove 37 and the first receiving groove 45;

[0100] A blower 23 is fixedly installed on the soil distribution cylinder 14, and an air supply pipe 43 is fixedly installed on the output end of the blower 23. The air supply pipe 43 is sleeved inside the rotating sleeve 42 and fixedly connected to the inner wall of the soil distribution cylinder 14; and

[0101] An air diversion protrusion 44 is located on the air supply pipe 43 and is slidably connected to the inner wall of the rotating sleeve 42. The air supply pipe 43 is also detachably connected to the through hole 40.

[0102] As the pipeline continues to be laid in the trench, the drive motor 15 is started, which drives the rotating sleeve 42 to rotate, and drives the soil-feeding rollers 31 and 39 to rotate synchronously. During the rotation of the soil-feeding rollers 31 and 39, the soil in the soil guide port 16 can enter the receiving trough 27 and the receiving trough 15. Since the receiving troughs 27 and 45 are different in size, as the rotating sleeve 42 drives the soil-feeding rollers 29 and 31 to rotate continuously, the soil in the receiving troughs 27 and 45 will be discharged to the outside of the soil distribution cylinder 14 through the side discharge port 22 and the middle discharge port 24 respectively under the action of gravity. As the equipment moves forward in the trench, the soil in the soil distribution cylinder 14 can be continuously added to the soil distribution cylinder 14 by workers manually or mechanically. To ensure timely replenishment, the outlet of the central outlet 24 is located behind the outlet of the side outlet 22, so that a certain amount of soil can be covered on both sides of the laid pipeline first. As the equipment moves forward, soil can be covered on top of the pipeline to prevent the pipeline from being deformed by pressure. In addition, the installed fan 23 can fill the air supply pipe 43 with high-pressure gas. When the rotating sleeve 42 rotates and the receiving tank 2 37 and receiving tank 1 45 are directly below, the through holes 40 in the receiving tank 2 37 and receiving tank 1 45 will contact the air diversion protrusion 44, so that the high-pressure gas in the air supply pipe 43 can be sprayed outward through the through holes 40. On the one hand, this can increase the rate at which soil falls from the receiving tank 2 37 and receiving tank 1 45. On the other hand, it can prevent a large amount of soil from adhering to the receiving tank 2 37 or receiving tank 1 45, affecting the subsequent soil discharge.

[0103] A method for laying concealed pipes for salt drainage, which uses the aforementioned equipment for laying concealed pipes for salt drainage, includes the following steps:

[0104] Step 1: First, place the V-shaped soil-moving seat 10 in the trench after the trenching is completed, and pass the pipe to be laid through the guide cylinder 3 and place it in the arc-shaped conveying trough 5. Then, fix the external traction equipment to the mounting base 2. Under the pulling action of the external traction equipment, the V-shaped soil-moving seat 10 and the support shell 12 move forward in the trench, while the pipe is continuously conveyed into the trench.

[0105] Step 2: During the pipeline laying process in Step 1, start the drive motor 15. The drive motor 15 drives the rotating sleeve 42 to rotate, and drives the first soil delivery roller 38 and the second soil delivery roller 39 to rotate synchronously, so as to discharge different amounts of soil stored in the first receiving tank 45 and the second receiving tank 37 to the sides and top of the pipeline through the side discharge port 22 and the middle discharge port 24 respectively.

[0106] Step 3: In step 2, while the middle outlet 24 discharges soil, it also flattens the soil covering the pipeline, thereby simultaneously limiting the pipeline in all directions.

[0107] It should be noted that, in this invention, unless otherwise explicitly specified and limited, the terms "sliding," "rotating," "fixed," and "equipped" should be interpreted broadly. For example, they can refer to welded connections, bolted connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0108] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
