Description

Technical Field

[0001] This utility model relates to the field of saline-alkali farmland planting technology, specifically a device for laying underground pipes for rapid salt drainage in saline-alkali land. Background Technology

[0002] Saline-alkali farmland commonly suffers from problems such as rapid surface salt return, poor soil permeability, and salt accumulation in the topsoil. If the salt in the soil cannot be drained in time, crop roots are easily damaged by the high-salt environment, leading to low germination rates, weak growth, or even failure to plant. To facilitate the drainage of salt into the ground, agricultural practices typically involve laying underground drainage pipes beneath the topsoil to divert saline water from the farmland, thereby improving the root growth environment. Therefore, laying these underground pipes is a crucial step in the improvement of saline-alkali land.

[0003] Currently, many areas still use manual pipe laying methods, requiring multiple people to follow behind the equipment to support the hoses and prevent them from tilting, jumping out of the trench, or being blown off course by the wind. Saline-alkali land is loose, windy, and full of potholes. The hoses themselves are lightweight and easily deformed, making manual laying labor-intensive and inefficient. Furthermore, it is difficult to ensure that the underground pipes are stably attached to the ground and maintain a fixed slope, which can easily affect the later salt drainage effect.

[0004] Even with the use of some existing simple pipe-laying equipment, several problems generally exist: the hose is prone to shaking or getting stuck at the conduit point, and tends to deviate from the trench wall during laying; the hose often floats in the trench or is dragged and arched; in typical saline-alkali environments such as strong winds and uneven ground, the hose is very easy to swing around or get out of the trench, requiring continuous manual intervention. It is still difficult to truly achieve stable, continuous, and highly efficient mechanized pipe laying.

[0005] Therefore, there is a need for a device for laying underground pipes to quickly drain salt from saline-alkali land, reducing manual labor and improving the quality and efficiency of underground pipe laying. Utility Model Content

[0006] The purpose of this invention is to provide a device for laying underground pipes for rapid salt drainage in saline-alkali land, so as to solve the problems mentioned in the background art, such as large amount of labor and low construction efficiency of manual laying, and difficulty in ensuring that the underground pipe can stably adhere to the bottom and maintain a fixed slope, which can easily affect the salt drainage effect in the later stage.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a buried pipe laying device for rapid salt drainage in saline-alkali land, comprising a pipe laying frame, a connecting assembly, a conduit assembly, and a pipe clamping assembly; the pipe laying frame includes a crossbeam, with side plates welded to both sides of the crossbeam, and a plow frame fixedly connected to the side plates and the crossbeam; the plow frame has a ditching plow fixedly installed at its bottom end for ditching and plowing; the connecting assembly includes a rotating frame rotatably connected to the center position above the crossbeam, with a hydraulic rod connecting frame fixedly sleeved on the outside of the rotating frame for connecting to the tractor hydraulic system; the conduit assembly includes... The connecting column is welded to the right wall of the pipe laying frame. Two sets of protective rings are fixedly connected to the outside of the connecting column. Each protective ring has a rotating wheel rotatably connected inside. The rotating wheels are fixedly connected to each other through a connecting shaft for guiding the pipeline. The pipe clamping assembly includes a metal clamp welded to the center of the bottom of the crossbeam. A track is opened at the front end of the metal clamp. A push-pull rod is movably connected inside the track. An inner clamping wheel is installed at the front end of the push-pull rod. Rotating blocks are rotatably connected to both sides inside the metal clamp. A clamping hand is rotatably connected inside the rotating block. A side clamping wheel is installed at the front end of the clamping hand for clamping the concealed pipe.

[0008] As a further technical solution of this utility model, the trenching plow blades are provided in two sets, symmetrically distributed below the crossbeam, for symmetrical excavation of underground pipe trenches.

[0009] As a further technical solution of this utility model, the hydraulic rod connecting frame rotates within a vertical range of 0-170° at the rotating frame, and the hydraulic rod connecting frame is turned by the tractor hydraulic system.

[0010] As a further technical solution of this utility model, a bearing is installed between the outer ring of the rotating wheel and the inner ring of the protective ring. The rotating wheel and the protective ring form a rolling friction structure through the bearing to reduce frictional resistance.

[0011] As a further technical solution of this utility model, the inner clamping wheel and the side clamping wheel are the same size, forming a triangular clamping structure. A welding rod is welded behind the protective ring, and a guide ring is welded to the top of the welding rod. The guide ring is a semi-circular tube with a groove at the top.

[0012] As a further technical solution of this utility model, a cylinder is fixedly connected to the bottom of the crossbeam through a connector, a movable groove is opened behind the metal clamp, and a fixed block is fixedly connected to the piston rod of the cylinder through the movable groove. The front end of the fixed block is fixedly connected to the push-pull rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up a pipe laying frame, connecting components, conduit components and pipe clamping components, this device can connect trenching, guiding, laying and clamping actions in a continuous manner, so as to achieve continuous and stable laying of underground pipes. In actual operation, only one tractor driver is needed to complete the whole process, without the need for many people to follow and watch the hose, thus reducing manual input. Under the unfavorable conditions of loose surface, large wind force changes and light weight of salt drainage hoses that are common in saline-alkali land, the device can still keep the hose laying path stable and close to the ground, thus improving laying efficiency.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 The present invention provides an embodiment of a buried pipe laying device for rapid salt drainage in saline-alkali land, comprising a pipe laying frame 1, a connecting component 2, a conduit component 3, and a pipe clamping component 4. The pipe laying frame 1 includes a crossbeam 104, with side plates 101 welded to both sides of the crossbeam 104. A plow frame 102 is fixedly connected to the side plate 101 and the crossbeam 104. A ditching plow 103 is fixedly installed at the bottom of the plow frame 102 for ditching and plowing.

[0018] Specifically, such as Figure 1 As shown, the paired ditching plow blades 103 directly cut the soil under the drive of the tractor, opening up the hard and sticky surface layer of the saline-alkali land in one go. The two plow blades work together to make the width and depth of the trench relatively stable. The soil in saline-alkali land is often hard and loose, and manual trenching is not continuous. The ditching plow blades 103 can make the trenches form a straight line, which makes it convenient for the salt drainage hose to adhere to the bottom.

[0019] The connecting component 2 includes a rotating frame 201 rotatably connected to the center position above the crossbeam 104. A hydraulic rod connecting frame 202 is fixedly sleeved on the outside of the rotating frame 201 for connecting the tractor hydraulic system. The hydraulic rod connecting frame 202 rotates within a vertical range of 0-170° at the rotating frame 201 and is turned by the tractor hydraulic system.

[0020] Specifically, such as Figure 1 As shown, after the rotating frame 201 and the hydraulic rod connecting frame 202 are connected to the hydraulic port of the tractor, the lifting and soil entry angle of the whole machine can be adjusted at any time. By adjusting the angle hydraulically, the trenching plow 103 can maintain a similar soil entry depth, the trench depth is consistent, and the drainage of the underground pipe is smooth in the later stage, without being too shallow or too deep.

[0021] The conduit assembly 3 includes a connecting column 301 welded to the right side wall of the pipe-laying frame 1. Two sets of protective rings 302 are fixedly connected to the outside of the connecting column 301. Each protective ring 302 is rotatably connected to a rotating wheel 305. The rotating wheels 305 are fixedly connected to each other by a connecting shaft 306 for guiding the pipeline. A bearing 307 is installed between the outer ring of the rotating wheel 305 and the inner ring of the protective ring 302. The rotating wheel 305 and the protective ring 302 form a rolling friction structure through the bearing 307 to reduce frictional resistance. The inner clamping wheel 410 and the side clamping wheel 408 are the same size and form a triangular clamping structure. A welding rod 304 is welded behind the protective ring 302. A conduit ring 303 is welded to the top of the welding rod 304. The conduit ring 303 is a semi-circular tube with a groove at the top.

[0022] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, after the salt drainage hose enters through the conduit assembly 3, it is first positioned by the conduit ring 303, and then falls onto the connecting shaft 306 under the rotor 305. When the tractor moves forward, the rotor 305 rotates accordingly, steadily sending the hose backward. In saline-alkali land, the wind is strong and the ground is uneven. By setting the conduit assembly 3, the hose always moves in the direction of the ditch, without the need for constant manual support. The bearing 307 between the rotor 305 and the protective ring 302 can reduce friction, so even if the hose gets muddy or wet, it can still be laid stably.

[0023] The pipe clamping assembly 4 includes a metal clamp 401 welded to the center of the bottom of the crossbeam 104. A track 409 is provided at the front opening of the metal clamp 401. A push-pull rod 405 is movably connected inside the track 409. An inner clamping wheel 410 is installed at the front end of the push-pull rod 405. Rotating blocks 407 are rotatably connected to both sides inside the metal clamp 401. A clamping hand 406 is rotatably connected inside the rotating block 407. A side clamping wheel 408 is installed at the front end of the clamping hand 406 for clamping the underground pipe. Two sets of trenching plows 103 are provided, symmetrically distributed below the crossbeam 104, for symmetrically excavating underground pipe trenches. A cylinder 402 is fixedly connected to the bottom of the crossbeam 104 through a connector. A movable groove 403 is provided behind the metal clamp 401. A fixing block 404 is fixedly connected to the piston rod of the cylinder 402 through the movable groove 403. The front end of the fixing block 404 is fixedly connected to the push-pull rod 405.

[0024] Specifically, such as Figure 1 and Figure 2 As shown, after the hose is delivered to the clamping assembly 4, the cylinder 402 pushes forward with the push-pull rod 405, and the clamp 406 opens or tightens, causing the inner clamping wheel 410 and the side clamping wheel 408 to form a triangular clamp. This will not flatten the hose or affect its forward movement, but it can provide a clamping force to the hose, allowing it to be laid along the bottom of the trench. This is especially effective for small-diameter salt drainage hoses, preventing them from bouncing up or deviating from the trench wall during laying, which would affect the subsequent drainage effect.

[0025] Working Principle: This device is towed by a tractor during operation. As the tractor moves the entire machine, the paired trenching blades 103 first cut into the soil, directly turning over the hard and easily broken surface layer of the saline-alkali land. The blade holder 102 maintains the synchronous depth of the two blades, creating a stable and continuous trench line, providing a continuous trench bottom for the burial of the underground pipe. Simultaneously, the tractor's hydraulic system continuously adjusts the depth of the machine's penetration through the rotating frame 201 and the hydraulic rod connecting frame 202. When encountering undulating terrain or changes in soil layers, the angle of the trenching blades 103 can be changed immediately to maintain a relatively consistent trench depth, thus ensuring stable burial depth and smooth slope for the subsequent salt drainage underground pipe. The salt drainage hose enters through the guide coil 303 of the guide assembly 3 and is pre-corrected in direction before falling into the two sets of... At the connecting shaft 306 between the protective rings 302, as the tractor moves forward, the rotating wheel 305 continuously rolls, smoothly delivering the hose towards the trench. The rolling structure of the bearing 307 reduces the resistance caused by mud and water adhesion, allowing the hose to move smoothly even in wet or loose environments in saline-alkali soil, without jumping or swaying. After the hose is delivered to the hose clamping assembly 4, the cylinder 402 generates reciprocating thrust through the fixed block 404 and the push-pull rod 405, causing the clamp 406 and the rotating block 407 to open and close. The inner clamping wheel 410 and the side clamping wheel 408 form a triangular pressing structure, providing continuous but not excessive ground pressure to the hose, ensuring that the hose always stays close to the bottom of the trench during movement, without deviating from the trench wall or being squeezed and deformed. This is especially effective when laying small-diameter hoses, reducing jumping and drifting.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
