Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a wheat planter that can be used for both drip irrigation and laying. Background Technology

[0002] Wheat is an important food crop in my country, ranking among the top in terms of both yield and planting area. However, with the continuous advancement of agricultural technology, the potential for wheat yield per unit area has reached a bottleneck. Drip irrigation and fertigation is a crucial link in improving wheat yield per unit area, enabling the reduction of ridges and the increase of arable land, while simultaneously providing precise water and fertilizer supply and efficient utilization of water and fertilizer.

[0003] The patent application number CN202411012729.0 proposes a seeder that integrates drip irrigation tape laying and fertilization. This device, combined with drip irrigation tape laying, fertilization and sowing, forms a new agricultural equipment. However, the drip irrigation tape in this device can only be laid on the shallow surface, and the drip irrigation tape exposed to the wind and sun in the farmland is easily damaged.

[0004] The patent application with application number CN202411127030.9 proposes an automatic drip irrigation tape laying device for a seeder terminal. The device is equipped with a soil covering plate, so that after laying, the drip irrigation tape can be covered with soil to avoid damage to the drip irrigation tape.

[0005] When laying pipelines in smaller farmland areas, a thicker main pipe is usually laid at the edge of the farmland, and then multiple drip irrigation tapes are laid in the farmland. After the main pipe is laid, an opening is made in it, and a two-way valve is assembled. Finally, the drip irrigation tapes are assembled onto the two-way valve.

[0006] However, for larger farmlands, simply installing a main pipe at the edge of the field results in insufficient water pressure and poor drip irrigation performance. Therefore, it is common practice to lay another main pipe in the middle of the farmland, such as... Figure 1 As shown, the drip irrigation tape 10 is laid longitudinally, and the main pipe is laid laterally perpendicular to it. After the drip irrigation tape is laid, the main pipe is laid. In the middle section of the farmland, the drip irrigation tape and the main pipe are connected by cutting the drip irrigation tape and assembling a three-way valve on the main pipe. The other two ends of the three-way valve are connected to the cut drip irrigation tape.

[0007] However, during the installation of drip irrigation tape, its tightness generally does not change significantly. There is no redundancy at the junction with the main pipe to connect with the three-way valve. In practice, it has been found that the lack of redundancy in the drip irrigation tape results in the connection section being in a taut state. This state will cause the drip irrigation tape to be subjected to excessive stress over a long period of time, leading to its damage. On the other hand, excessive stress will also cause the connection between the drip irrigation tape and the three-way valve to be loose, making it prone to leakage. Summary of the Invention

[0008] To address the shortcomings of existing technologies, this invention provides a dual-purpose drip irrigation and seeding machine for wheat. It solves the problem that during drip irrigation tape installation, the tightness of the tape remains largely unchanged, and there is no redundancy at the junction with the main pipe to connect to the three-way valve. This results in the connection section being taut, which on the one hand causes the drip irrigation tape to be subjected to excessive stress over a long period, leading to damage; on the other hand, excessive stress also causes the connection between the tape and the three-way valve to be loose.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a wheat seeder that combines drip irrigation and laying, comprising a seeding device and a drip irrigation laying device located behind the seeding device, the drip irrigation laying device comprising:

[0010] Installation box;

[0011] A furrow opener, located below the mounting box, is used to create furrows for the drip irrigation tape;

[0012] The tensioning wheel assembly is located inside the mounting box, and the drip irrigation tape passes through the tensioning wheel assembly from top to bottom;

[0013] A soil covering disc is located behind the trencher and is rotatably mounted on the trencher via a pin at the head of the connecting frame.

[0014] The pressure roller, located at the tail of the furrow opener, is used to press the drip tape that has passed through the tensioning roller assembly into the furrow.

[0015] A movable structure, installed on one side of the mounting box, is used to adjust the position of the tension wheel assembly so that the tension of the drip irrigation tape can be reduced in a short time.

[0016] A lifting assembly, mounted on a mounting box, is used to raise the soil covering plate when the tension of the drip irrigation tape decreases.

[0017] Furthermore, an acceleration component is provided between the central shaft and the pin shaft of the pressure roller to accelerate the laying of the drip irrigation tape when the tension of the drip irrigation tape decreases in a short time, forming a state of laying redundant drip irrigation tape in the required road section, and the redundant drip irrigation tape is not covered with soil.

[0018] Furthermore, the lifting assembly includes a steel rope body and a steel rope winding wheel. The steel rope winding wheel is located inside the mounting box. The steel rope winding wheel winds the steel rope body to make the connecting frame rotate on the connecting frame via a pin, thereby lifting the soil covering plate.

[0019] Furthermore, the lifting assembly also includes a winding gear, which is mounted on the central shaft of the steel rope winding reel, and a rack plate meshes above the winding gear. The rack plate is connected to the tensioning wheel assembly, so that the tensioning wheel assembly drives the rack plate to move when it moves with the moving structure.

[0020] Furthermore, the lifting assembly also includes:

[0021] The inner core is fixed at the center of the steel rope winding wheel, and the axial direction of the steel rope winding wheel is in the same direction as the movement direction of the tension wheel assembly.

[0022] The movable rod moves together with the tensioning wheel assembly and passes through the inner core. The inner core cavity is provided with a slider, and the movable rod is provided with a spiral groove adapted to the slider.

[0023] Furthermore, the acceleration component includes:

[0024] A sector gear, wherein the sector gear is located on one side of the head of the connecting frame and is concentric with the pin shaft;

[0025] Accelerating gear one, which is located on one side of the sector gear, can mesh with the sector gear or not mesh with it. Accelerating gear one is also provided with gear two coaxial with it. Gear three meshes on one side of gear two, and gear four meshes below gear three. Gear four is fixed to one end of the central shaft of the pressure roller.

[0026] After the connecting frame is lifted by the lifting component by 2°-4°, the sector gear and the acceleration gear begin to mesh.

[0027] Furthermore, a limiting block is provided on the other side edge of the head of the connecting frame, and an unlocking component is also provided inside the mounting box. The unlocking component is used to restrict the connecting frame to have the required deflection degree of freedom when it is not being lifted, so that the soil covering plate can avoid hard objects in the soil, and is used to no longer restrict its deflection angle when the connecting frame is being lifted.

[0028] Furthermore, the unlocking component includes:

[0029] The C-shaped frame is located on the side of the connecting frame head near the limiting block. When the connecting frame is not being lifted, the C-shaped frame limits the deflection angle of the connecting frame by restricting the position of the limiting block.

[0030] A pressure bar is fixed to the tension wheel assembly and moves synchronously with the tension wheel assembly. A force-bearing plate is provided inside the mounting box on the moving path of the tension wheel assembly. A pressure plate is provided between the force-bearing plate and the C-shaped frame. The force-bearing plate has an inclined surface.

[0031] Spring 2 is used to connect the force-bearing plate to the bottom surface of the mounting box.

[0032] Furthermore, a tension spring is installed between the connecting frame and the mounting box to reset the connecting frame after it loses its lifting force.

[0033] Furthermore, a front guide wheel is provided at the top inside the mounting box, and a rear guide wheel is provided at the bottom inside the mounting box, with the drip irrigation tape forming a V-shaped structure between the front guide wheel, the tension wheel assembly, and the rear guide wheel.

[0034] The present invention has the following beneficial effects:

[0035] (1) This drip irrigation laying and two-in-one wheat planter can lay drip irrigation tape in large farmland. When the drip irrigation tape reaches the position of the main pipe, it releases the excess drip irrigation tape and raises the soil covering plate at this stage, so that the operator can cut the drip irrigation tape and have enough length to connect it to the main pipe. This avoids the drip irrigation tape being in a taut state when connecting, avoids the drip irrigation tape being easily damaged due to excessive stress, and also ensures the tightness of the connection between the drip irrigation tape and the T-junction.

[0036] (2) The drip irrigation laying and laying wheat planter can make the pressure roller rotate actively and accelerate the rotation during use, thereby quickly laying the released drip irrigation tape, ensuring the formation of redundant sections, and reserving the required length for shearing and assembling the drip irrigation tape on the three-way valve of the main pipe.

[0037] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0052] 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.

[0053] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0054] The following is based on Figures 1-13 This invention describes a wheat seeder that can be used for both drip irrigation and laying, as provided in an embodiment of the invention.

[0055] Example 1

[0056] Please see Figure 2 and Figure 3 This invention provides a technical solution: a drip irrigation and laying dual-purpose wheat planter, including a sowing device 1, a drip irrigation laying device located behind the sowing device 1, and a compaction wheel 2 located behind the drip irrigation tape laying device. The device is assembled on a vehicle. The sowing device 1 is used for sowing while the vehicle is moving, the drip irrigation laying device is used for laying the drip irrigation tape 10 while the vehicle is moving, and the compaction wheel 2 is used for compacting the soil.

[0057] Combination Figures 2-7 The drip irrigation laying device shown includes a drip irrigation roll support frame 3 and a drip irrigation roll 4 mounted on the drip irrigation roll support frame 3. The drip irrigation roll support frame 3 is mounted on the machine frame. A U-shaped frame 5 is also mounted on the machine frame for assembling a furrow opener 16 below it. The furrow opener 16 is used to gradually open furrows in the direction of vehicle movement. An installation box 51 is also mounted on the U-shaped frame 5. In order to allow the drip irrigation tape 10 to enter the furrow formed by the furrow opener 16 during vehicle movement, a front guide wheel 15 is mounted at the top inside the installation box 51, a rear guide wheel 18 is mounted at the bottom inside the installation box 51, a tension wheel assembly 6 is mounted on one side of the middle of the installation box 51, and a pressure wheel 17 is mounted at the tail inside the furrow opener 16. The drip irrigation tape unwound from the drip irrigation roll 4 passes sequentially through the front guide wheel 15, the tension wheel assembly 6, the rear guide wheel 18, and the pressure wheel 17, and is pressed into the furrow by the pressure wheel 17.

[0058] Preferably, an auxiliary wheel 171 is provided on the side of the pressure wheel 17 near the drip irrigation belt 10.

[0059] Furthermore, an openable door is provided on the mounting box 51 to facilitate the operator to pass the drip irrigation tape 10 through each wheel.

[0060] Preferably, a smoothing frame 19 is also provided on the frame, which allows the drip irrigation tape 10 to pass through the smoothing frame 19 after it is released from the drip irrigation reel 4, so that the smoothing frame 19 can smooth it. The smoothing frame 19 includes a steel pipe and a PVC plastic pipe, and the plastic pipe is rotatable.

[0061] The reason for setting up the tensioning wheel assembly 6 is that the vehicle does not travel at a constant speed during the driving process, and there will inevitably be uneven driving speed. The tensioning wheel assembly 6 can be used to compensate for this speed difference, thereby avoiding the drip irrigation tape 10 being laid too tightly or too loosely.

[0062] Since larger farmlands require the installation of main pipelines in the middle, the drip irrigation tape 10 needs to be cut in the area where the main pipeline will be installed. To facilitate cutting the drip irrigation tape 10 and to allow sufficient installation length, the drip irrigation tape 10 forms a V-shape between the front guide wheel 15, the tension wheel assembly 6, and the rear guide wheel 18. A movable structure 11 is also provided, installed on one side of the mounting box 51, for adjusting the position of the tension wheel assembly 6. This allows the tension of the drip irrigation tape to decrease quickly, so that when the vehicle travels to the area in the middle of the farmland where the main pipeline needs to be installed, the driver can operate the movable structure 11 to adjust the position. Figure 6 Moving to the left from the perspective shown reduces the tension of the entire tensioning wheel assembly 6 on the drip irrigation tape 10, releasing more of the drip irrigation tape 10 and providing sufficient connection length for the cut drip irrigation tape 10. This prevents the already laid drip irrigation tape 10 from becoming too tight due to the operator pulling the drip irrigation tape 10 too hard on the three-way valve of the main pipe.

[0063] Optionally, the movable structure 11 is a cylinder, a hydraulic cylinder, or an electric telescopic rod.

[0064] like Figure 5 and Figure 7 As shown, the tensioning wheel assembly 6 mentioned above also has a certain tensioning performance when the moving structure 11 does not drive its movement. Specifically, the tensioning wheel assembly 6 includes a tensioning wheel body 61 and an auxiliary wheel 62 located on one side of the tensioning wheel body 61. The drip irrigation tape 10 can pass through the tensioning wheel body 61 and the auxiliary wheel 62. A side frame 63 is provided at the end of the tensioning wheel body 61 and the auxiliary wheel 62. The side frame 63 can move along the driving direction of the moving structure 11 on the inner wall of the mounting box 51. A guide rod 66 is sleeved inside the side frame 63. One end of the guide rod 66 is provided with a limiting plate 67, and the other end is provided with a connecting plate 64. A tension spring 65 is provided between the connecting plate 64 and the side frame 63. The other side of the connecting plate 64 is connected to the moving structure 11. When the moving structure 11 does not drive the connecting plate 64 to move, the connecting plate 64 locks the approximate position of the entire tension wheel assembly 6. At this time, the drip irrigation tape 10 can adjust the tension through the tension spring 65. When the moving structure 11 is working, the connecting plate 64 will first drive the guide rod 66 to move, and then drag the entire tension wheel assembly 6 to move together.

[0065] Combination Figures 6-10 As shown, in order to reduce the impact of external weathering on the drip irrigation tape 10, the drip irrigation tape 10 entering the soil trench is covered with soil. Therefore, a soil covering plate 12 is also set here. The soil covering plate 12 consists of two discs. The two discs are located behind the furrow opener 16 and on both sides of the trench, and are used to cover the soil generated when the furrow opener 16 opens the trench back onto the drip irrigation tape 10.

[0066] Preferably, the two discs are rotatably mounted on the furrow opener 16 via the pin 131 at the head of the connecting frame 13, so that they can move together with the furrow opener 16 and can be deflected at a certain angle on the furrow opener 16 to avoid being damaged when encountering hard materials in the soil.

[0067] Combination Figure 7 and Figure 10 As shown, it should be noted that when the vehicle reaches the area where the drip irrigation tape 10 needs to be connected to the main pipe, the tensioning wheel assembly 6 releases the drip irrigation tape 10. At this time, there is no need to cover the released redundant drip irrigation tape 10 with soil. Therefore, a lifting assembly 7 is set here. The lifting assembly 7 is located on the mounting box 51 and is used to raise the soil covering plate 12 when the tension of the drip irrigation tape decreases. At this time, the soil covering plate 12 is no longer covered with soil, thereby achieving the desired purpose. The desired purpose is that when the drip irrigation tape 10 reaches the area connected to the main pipe, the redundant drip irrigation tape 10 is released and the redundant drip irrigation tape 10 is no longer covered with soil, so that the operator can easily cut the drip irrigation tape 10 and have enough length to connect it to the main pipe, avoiding the drip irrigation tape 10 being in a taut state when connected.

[0068] Therefore, the drip irrigation laying and laying dual-purpose wheat planter provided in this embodiment of the invention can lay drip irrigation tape 10 in a large farmland. When the drip irrigation tape 10 reaches the laying position of the main pipe, the redundant drip irrigation tape 10 is released, and the soil covering plate 12 is lowered and raised at this stage, so that the operator can easily cut the drip irrigation tape 10 and have enough length to connect it to the main pipe, avoiding the drip irrigation tape 10 being in a taut state when connecting.

[0069] In actual operation, although the tensioning wheel assembly 6 can quickly release the drip irrigation tape 10, the pressure wheel 17 cannot quickly lay it down. Therefore, in this embodiment, an acceleration assembly 8 is also provided between the central shaft and the pin 131 of the pressure wheel 17, so that when the drip irrigation tape 10 is released in a short time, the pressure wheel 17 can accelerate the laying of the drip irrigation tape 10, forming a state of laying redundant drip irrigation tape 10 in the required paving section, and the redundant drip irrigation tape is not covered with soil.

[0070] Specifically, the aforementioned lifting assembly 7 includes a steel rope body 71 and a steel rope winding wheel 73. The steel rope winding wheel 73 is located inside the mounting box 51. The steel rope winding wheel 73 winds up the steel rope body 71 to make the connecting frame 13 rotate on the connecting frame 13 via the pin 131, thereby lifting the soil covering plate 12.

[0071] In this embodiment, the steel rope body 71 is fixed between the steel rope winding wheel 73 and the connecting frame 13. Therefore, when the steel rope winding wheel 73 winds up the steel rope body 71, the steel rope body 71 can pull the connecting frame 13, causing it and the pin 131 to rotate on the trencher 16, thereby lifting it.

[0072] Preferably, a tension spring 14 is installed between the connecting frame 13 and the mounting box 51, so that after the connecting frame 13 loses its lifting force, it can be stably reset downwards into the trench opened by the trencher 16 for soil covering.

[0073] In addition, in order to prevent the covering disc 12 from performing soil covering operations when the tensioning wheel assembly 6 is released, a winding gear 74 is also provided. The winding gear 74 is installed on the central shaft of the steel rope winding wheel 73, and a rack plate 75 meshes above the winding gear 74. The rack plate 75 is connected to the tensioning wheel assembly 6, so that when the tensioning wheel assembly 6 moves with the moving structure 11, it drives the rack plate 75 to move. When the rack plate 75 moves and passes the winding gear 74, the winding gear 74 can drive the steel rope winding wheel 73 to rotate and wind up the steel rope body 71.

[0074] Reference Figures 7-10 As shown, the aforementioned acceleration component 8 includes a sector gear 81 and an acceleration gear 82.

[0075] Specifically, sector gear 81 is located on one side of the head of connecting frame 13 and is concentric with pin 131. Acceleration gear 1 82 is located on one side of sector gear 81. Acceleration gear 1 82 can mesh with sector gear 81 or not. When sector gear 81 rotates 2°-4°, sector gear 81 can mesh with acceleration gear 1 82. Acceleration gear 1 82 is also provided with gear 2 83 coaxial with it. Gear 3 84 meshes on one side of gear 2 83. Gear 4 85 meshes below gear 3 84 and gear 4 85 is fixed to one end of the central shaft of pressure roller 17.

[0076] In this embodiment, when the connecting frame 13 is lifted by the lifting component 7 by 2°-4°, the sector gear 81 begins to mesh with the acceleration gear 1 82 and drives the acceleration gear 1 82 to rotate. The rotation of the acceleration gear 1 82 can drive the gear 2 83 to rotate, and then the gear 2 83 can drive the gear 3 84 to rotate, further accelerating the gear 3 84. The gear 3 84 can drive the gear 4 85 to rotate, so that the pressure roller 17 can rotate. Here, the gear 3 84 also plays a steering role, so that the rotation direction of the pressure roller 17 is the direction of pulling the released drip irrigation tape 10, so that the pressure roller 17 actively and quickly lays the drip irrigation tape 10, thereby forming redundant drip irrigation tape 10.

[0077] The reason why the sector gear 81 only starts to mesh with the acceleration gear 82 after the connecting frame 13 is lifted by the lifting component 7 by 2°-4° is that when the connecting frame 13 is not lifted, the connecting frame 13 and the soil covering plate 12 should also have a certain degree of rotational freedom. This degree of freedom is to avoid the soil covering plate 12 being blocked when it touches the hard structure in the soil and thus unable to cover the soil or move forward. When the connecting frame 13 rotates within this degree of freedom (2°-4° in each direction), the pressure roller 17 will not rotate actively, nor will it accelerate the laying of the drip irrigation tape 10. It only moves in the trench due to the movement of the vehicle.

[0078] Preferably, the central angle of the sector gear 81 is 45°-70°.

[0079] like Figure 11 To avoid the situation where the soil covering plate 12 cannot cover the soil due to excessive deflection when the redundant drip irrigation tape 10 is not released, a limiting block 132 is provided on the other side edge of the head of the connecting frame 13. The installation box 51 is also provided with an unlocking component 9. The unlocking component 9 is used to restrict the connecting frame 13 to have the required degree of deflection freedom when it is not lifted, so that the soil covering plate 12 can avoid hard objects in the soil. It is also used to no longer restrict the deflection angle when the connecting frame 13 is lifted, so that the connecting frame 13 can deflect 2°-4° in both directions when it is not lifted, and can deflect to the required angle when it is lifted.

[0080] For details, please refer to... Figure 11 As shown, the unlocking component 9 includes a C-shaped frame 93, a pressure rod 95, and a spring 94.

[0081] The C-shaped frame 93 is located on the side of the head of the connecting frame 13 near the limiting block 132. When the connecting frame 13 is not being lifted, the C-shaped frame 93 limits the position of the limiting block 132 to control the deflection angle of the connecting frame 13.

[0082] The pressure bar 95 is fixed on the tension wheel assembly 6 (fixed below one of the side frames 63) and moves synchronously with the tension wheel assembly 6. The mounting box 51 is provided with a force plate 91 on the moving path of the tension wheel assembly 6. A pressure plate 92 is provided between the force plate 91 and the C-shaped frame 93. The force plate 91 has an inclined surface.

[0083] In this embodiment, when the moving structure 11 drives the tensioning wheel assembly 6 to release the drip irrigation tape 10, the side frame 63 can drive the pressure rod 95 to move. The pressure rod 95 moves on the inclined plane and pushes the pressure plate 92 downward, causing the C-shaped frame 93 to move downward. As a result, the lower side of the C-shaped frame 93 loses its restriction on the limiting block 132. At this time, the connecting frame 13 can deflect at a large angle.

[0084] Preferably, a second spring 94 is also provided, which is used to connect the force plate 91 and the bottom surface of the mounting box 51, and is used to restore the pressure plate 92 to its original height after it loses the pressure of the pressure rod 95.

[0085] During use (operation), the driver drives the vehicle to move the device in the farmland. The sowing device 1 can perform sowing operations. The drip irrigation tape laying device is used to lay the drip irrigation tape 10. The process of laying the drip irrigation tape 10 is as follows: as the vehicle moves, the drip irrigation tape 10 is unwound by the drip irrigation reel 4. The drip irrigation tape unwound from the drip irrigation reel 4 passes sequentially through the front guide wheel 15, the tension wheel assembly 6, the rear guide wheel 18, and the pressure wheel 17. At the same time, as the vehicle moves, the furrow opener 16 can open furrows in the soil. The drip irrigation tape 10 is pressed into the furrow by the pressure wheel 17. The tension spring 65 in the tension wheel assembly 6 can automatically adjust the tension of the drip irrigation tape 10. Meanwhile, the soil covering plate 12 is used to cover the drip irrigation tape 10 with the soil generated when the furrow opener 16 opens the furrows, so as to achieve shallow burial of the drip irrigation tape 10. During this process, the connecting frame 13 and the pin 131 can deflect to a certain extent on the furrow opener 16 to avoid hard structures in the soil.

[0086] When the vehicle reaches the area in the middle of the farmland where the main pipe is to be laid, the movable structure 11 can be driven to work, which will drive the connecting plate 64 to move. At this time, the connecting plate 64 will first drive the guide rod 66 to move, and then drag the entire tensioning wheel assembly 6 to move together. Thus, the tensioning wheel assembly 6 can release the drip irrigation tape 10. At the same time, the tensioning wheel assembly 6 drives the rack plate 75 to move. When the rack plate 75 moves and passes the winding gear 74, the winding gear 74 can drive the steel rope winding wheel 73 to rotate and wind up the steel rope body 71, so that the connecting frame 13 can deflect. When it is lifted, the soil covering plate... 12 is raised and no longer covered with soil. Due to the action of the unlocking component 9, the connecting frame 13 can deflect without restriction. When the connecting frame 13 deflects, it drives the sector gear 81 to rotate. After the sector gear 81 rotates 2°-4°, the sector gear 81 can mesh with the acceleration gear 1 82. Through the acceleration and steering action of the acceleration gear 1 82, gear 2 83, gear 3 84, and gear 4 85, the pressure roller 17 accelerates and rotates actively, and lays the drip irrigation tape 10 to form a redundant, uncovered drip irrigation tape 10, which facilitates its connection with the main pipe.

[0087] After the redundant section is laid (in fact, the laying time of the redundant section is very short, that is, after the moving structure 11 pulls the tension wheel assembly 6, the laying of the redundant section is already completed, and at this time the pressing wheel 2 presses the redundant section on the bottom), the moving structure 11 drives the tension wheel assembly 6 to reset, and the tension wheel assembly 6 pulls the drip irrigation tape 10 above, so that the drip irrigation reel 4 is quickly unwound until the tension wheel assembly 6 is completely reset and the unwound of the drip irrigation tape 10 is restored to balance, and the drip irrigation tape 10 is continuously laid.

[0088] Example 2

[0089] Combination Figure 12 and Figure 13 As shown, the difference between this embodiment and Embodiment 1 is that the rotation method of the steel rope winding wheel 73 is different, and an inner core 76 moving rod 77 is provided here.

[0090] The inner core 76 is fixed at the center of the steel rope winding wheel 73, and the axial direction of the steel rope winding wheel 73 is in the same direction as the moving direction of the tension wheel assembly 6. The moving rod 77 is fixed on the connecting plate 64 and can move together with the tension wheel assembly 6. The moving rod 77 passes through the inner core 76. The inner cavity of the inner core 76 is provided with a slider, and the moving rod 77 is provided with a spiral groove 78 that matches the slider.

[0091] This implementation scheme only enables the moving rod 77 to move axially within the inner cavity of the inner core 76 when the tensioning wheel assembly 6 moves, so that the slider can slide within the spiral groove 78 and drive the steel rope winding wheel 73 to rotate.
