Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of drip irrigation tape laying, in particular to a drip irrigation tape laying end self-fixing and shearing device. BACKGROUND

[0002] The statements herein merely provide background technology related to the present application, and do not necessarily constitute prior art.

[0003] In Xinjiang, a new type of slope water-saving drip irrigation technology is emerging, which forms a slope by slope in the field, then plants food crops on the slope, and drips irrigation at the top of the slope in the form of point source or line source, which can greatly reduce the use of drip irrigation tape per unit area, and at the same time can provide sufficient irrigation for farrowing wheat.

[0004] At present, in the above-mentioned slope water-saving drip irrigation technology, the drip irrigation tape laying mechanism is usually installed at the rear of the agricultural machine, and the agricultural machine travels in the process, and the drip irrigation tape laying mechanism digs ditch and lays drip irrigation tape at the top of the slope. When laying drip irrigation tape, it usually needs manual fixing of one end of the drip irrigation tape in the field (fixed by stepping) in the initial stage, and then the agricultural machine starts to travel, and the ditching part on the drip irrigation tape laying mechanism breaks the soil and digs ditch at the top of the slope. During the travel of the agricultural machine, the drip irrigation tape wound into a disc on the agricultural machine is automatically unwound under tension, enters the pre-buried ditch behind the ditching part through the preset guide groove, and then the soil covering plate installed behind the ditching part covers the drip irrigation tape. After traveling a sufficient distance, the fixed end of the drip irrigation tape is loosened (i.e. the foot is lifted), and the friction between the soil and the drip irrigation tape enables the drip irrigation tape to continue to prevent winding. In addition, after completing the drip irrigation tape laying of one slope, manual cutting of the drip irrigation tape is needed to turn the agricultural machine to the next slope for operation.

[0005] The above-mentioned drip irrigation tape laying mechanism needs manual fixing of one end of the drip irrigation tape for a long time, and manual cutting of the drip irrigation tape, which affects the overall work efficiency. SUMMARY

[0006] The purpose of the present application is to provide a drip irrigation tape laying end self-fixing and shearing device to solve the above-mentioned problems.

[0007] To solve the above-mentioned technical problems, the present application adopts the following technical solutions: A drip irrigation tape laying end self-fixing and shearing device, comprising: a fixed plate; a ditching part arranged at the bottom of the fixed plate for breaking soil and digging a drip irrigation tape pre-buried ditch; The unwinding component is located at the bottom of the fixed plate and behind the trenching component in the direction of travel. It includes two rotating shafts that are rotatably set at the bottom of the fixed plate and arranged in parallel, and a power component that drives one of the rotating shafts to rotate. The drip irrigation tape passes through the gap between the two rotating shafts from top to bottom and is clamped by the two rotating shafts. The rotation of the rotating shafts applies a tensile force to the drip irrigation tape to achieve the laying of the drip irrigation tape. The pressing component is located at the tail end of the fixed plate in the direction of travel. The pressing component has the functions of rotation and extension. It is used to press the end of the drip irrigation tape in the initial state, and rotate upward after the fixed plate has traveled a specified distance to release the pressure on the drip irrigation tape.

[0008] Furthermore, the pressing component includes a groove formed on the fixed plate, a slider slidably disposed in the groove, and a pressure plate rotatably connected to the slider. The groove includes a cavity formed inside the fixed plate. One end of the cavity passes through the tail end of the fixed plate in the direction of travel. The cavity is provided with a clearance opening above the tail end of the fixed plate to avoid the upward rotation of the pressure plate. The pressure plate is L-shaped. One side of the L-shape is rotatably engaged with the slider and can slide inside the cavity. A first torsion spring is provided between the slider and the pressure plate to drive the pressure plate to rotate upward. The other side of the L-shape is used to press the drip irrigation tape. It also includes a reset component for sliding the slider into the interior of the chamber, so that one side of the L-shape extends into the chamber and rotates downward within the chamber's boundaries.

[0009] Furthermore, the reset component includes a first upright rod mounted on a fixed plate, a first pulley rotatably mounted on the first upright rod, and a lifting platform mounted below the first pulley. The bottom of the lifting platform is provided with a rolling element that passes through the fixed plate. The rolling element is used to contact the ground and moves downward when the fixed plate is raised. It also includes a first traction rope, which passes around a first pulley and connects to the lifting platform and the slider, and is used to drive the slider to slide into the interior of the chamber when the fixed plate is lifted.

[0010] Furthermore, a spring is provided between the lifting platform and the fixed plate, and the spring is used to drive the lifting platform to move downward when the fixed plate is raised; a counterweight is also provided on the lifting platform to increase the load of the lifting platform moving downward.

[0011] Furthermore, it also includes a shearing component, which is located at the rear of the fixed plate in the direction of travel and behind the pressing component. The fixed plate has a clearance groove at the position between the shearing component and the pressing component to allow the pressing component to extend and retract. The fixed plate also has a through groove at the position of the shearing component. The shearing component includes a movable block disposed at the through slot, the bottom of which can extend out of the through slot to below the fixed plate. It also includes two shearing blades, the tops of which are rotatably connected to the bottoms of the movable block. A second torsion spring is disposed between the two shearing blades. The second torsion spring is used to move the bottoms of the two shearing blades away from each other. The two shearing blades cooperate to shear the material. It also includes a lifting connector, one end of which is connected to the lifting platform and the other end of which is connected to the moving block. When the lifting platform moves downward, it drives the moving block to move upward. When the moving block moves upward, it drives the two shearing blades to move upward together. Under the limitation of the through slot, the two shearing blades come together to form a shearing action until the tops of the two shearing blades pass through the through slot.

[0012] Furthermore, the lifting connector includes a second upright rod disposed on the fixed plate, the second upright rod being located at the through slot, a second pulley being disposed on the second upright rod, a second traction rope and a third pulley disposed on the first upright rod, the second traction rope passing around the second pulley and the third pulley, and its two ends being connected to the lifting platform and the moving block, for driving the moving block to move upward when the fixed plate is lifted.

[0013] Furthermore, a connecting rod is provided on the second upright, the second pulley is rotatably mounted on the connecting rod, a fourth pulley is rotatably mounted on the top of the movable block, one end of the second traction rope is fixed relative to the connecting rod, the second traction rope passes around the fourth pulley and the second pulley to form a pulley group, the fourth pulley is the movable pulley in the pulley group, and the second pulley is the fixed pulley in the pulley group.

[0014] Furthermore, the trenching component is a wedge-shaped block, with its end away from the unwinding component being triangular and used to break the soil to form a pre-buried trench. The bottom of the wedge-shaped block is a flat surface, and a rotating cavity is also provided at the bottom of the wedge-shaped block. A ground roller is rotatably arranged in the rotating cavity. The ground roller has multiple rolling teeth, which can extend out of the rotating cavity to the bottom of the wedge-shaped block and contact the bottom surface of the pre-buried trench. The ground roller can rotate synchronously with the movement of the wedge-shaped block to loosen the soil at the bottom of the pre-buried trench. The bottom of the lifting platform extends into the rotating cavity, and the ground roller also serves as a rolling component, rotatably installed at the bottom of the lifting platform.

[0015] Furthermore, the power component includes a power shaft rotatably mounted on the bottom of the fixed plate. The power shaft is arranged parallel to two rotating shafts. A first gear is mounted on the power shaft, and a second gear meshing with the first gear is mounted on the rotating shaft near the power shaft. At least one end of the power shaft is provided with a rotating wheel, which is used to contact the ground and drive the power shaft to rotate during travel. The linear velocity of the rotating wheel is equal to the linear velocity of the outer surface of the rotating shaft.

[0016] The beneficial effects of this invention are reflected in: This invention utilizes agricultural machinery to move a fixed plate. As the fixed plate moves, the ditching component breaks the soil and opens a ditch at the top of the slope. Simultaneously, the power unit applies tension to the drip irrigation tape to unwind it. After traveling a designated distance, the fixed plate rotates upward, releasing the pressure on the drip irrigation tape. Thus, in the initial stage of laying the drip irrigation tape, it is not necessary to manually fix one end of the tape, effectively improving the efficiency of manual work. Furthermore, the pressing component can effectively fix the end of the drip irrigation tape in the initial state, preventing displacement of the drip irrigation tape due to delays or movement differences of the power unit during the initial laying process.

[0019] 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 a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. 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.

[0020] Please see Figures 1-8 This invention discloses a self-fixing and shearing device for the end of drip irrigation tape, comprising: Fixing plate 1; The trenching component 2 is set at the bottom of the fixing plate 1 and is used to break the soil to open the trench for pre-burying the drip irrigation tape; The unwinding component 3 is located at the bottom of the fixed plate 1 and behind the trenching component 2 in the direction of travel. It includes two rotating shafts 31 that are rotatably set at the bottom of the fixed plate 1 and arranged in parallel, and a power component that drives one of the rotating shafts 31 to rotate. The drip irrigation tape passes through the gap between the two rotating shafts 31 from top to bottom and is clamped by the two rotating shafts 31. The rotation of the rotating shafts 31 applies a pulling force to the drip irrigation tape to achieve the laying of the drip irrigation tape. The pressing component 5 is located at the tail end of the fixed plate 1 in the direction of travel. The pressing component 5 has the functions of rotation and extension. It is used to press the end of the drip irrigation tape in the initial state and rotate upward after the fixed plate 1 has traveled a specified distance to release the pressure on the drip irrigation tape.

[0021] In practice, in the initial state, the pressing component 5 presses down on the end of the drip irrigation tape to prevent it from deviating (simple manual assistance can be used to ensure the tape lands in the designated position). Then, the agricultural machinery is started, and the fixed plate 1 is moved by the machinery. As the fixed plate 1 moves, the ditching component 2 breaks the soil and opens a ditch at the top of the slope. At the same time, the power component starts to apply tension to the drip irrigation tape to unwind it. After traveling a designated distance (e.g., 20 cm), the fixed plate 1 rotates upward to release the pressure on the drip irrigation tape. In this way, in the initial stage of laying the drip irrigation tape, it is not necessary to manually fix one end of the tape. Furthermore, because the power component has a delay in the initial state (it only starts after the agricultural machinery has moved), and there is a difference between the moving speed of the agricultural machinery and the linear speed of the rotating shaft 31 (i.e., the distance swept by a point on the outer surface of the rotating shaft 31 per unit time), the pressing component 5 can effectively fix the end of the drip irrigation tape in the initial state, preventing large displacement of the tape end.

[0022] Preferably, the system also includes a linkage assembly disposed on the fixed plate 1, which is used to connect the fixed plate 1 to the agricultural machinery. It should be noted that the linkage assembly can be any commonly used linkage assembly for connecting agricultural machinery in the prior art (the figure is for illustrative purposes only), therefore, the structure of the linkage assembly will not be described in detail here.

[0023] In one embodiment, the pressing component 5 includes a groove 13 formed on the fixed plate 1, a slider 51 slidably disposed in the groove 13, and a pressure plate 52 rotatably connected to the slider 51. The groove 13 includes a cavity formed inside the fixed plate 1. One end of the cavity passes through the tail end of the fixed plate 1 in the direction of travel. The cavity is provided with a clearance opening above the tail end of the corresponding fixed plate 1 to avoid the upward rotation of the pressure plate 52. The pressure plate 52 is L-shaped. One side of the L-shape is rotatably engaged with the slider 51 and can slide inside the cavity. A first torsion spring (not shown in the figure) is provided between the slider 51 and the pressure plate 52 to drive the pressure plate 52 to rotate upward. The other side of the L-shape is used to press the drip irrigation tape. It also includes a reset component 6, which slides the pull slider 51 into the interior of the chamber, so that one side of the L-shape extends into the chamber and rotates downward under the limitation of the chamber.

[0024] In practice, initially, one side of the pressure plate 52 is located inside the cavity, while the other side of the pressure plate 52 faces downward. When the agricultural machinery drives the fixed plate 1 to fall, the end of the pressure plate 52 presses down on the drip irrigation tape. During the movement of the fixed plate 1, the pressing force applied by the pressure plate 52 to the drip irrigation tape in turn forms a pulling force on the pressure plate 52, causing one side of the pressure plate 52 to gradually move towards the outside of the cavity until the pressure plate 52 moves to the opening. At this time, the torque of the first torsion spring is released, causing the pressure plate 52 to rotate upward to release the pressure on the drip irrigation tape.

[0025] It should be noted that the ability of agricultural machinery to raise and lower the fixed plate 1 is common knowledge to those skilled in the art, and therefore will not be elaborated upon here.

[0026] Of course, the pressing component 5 can also be formed by setting a combination of a rotating motor and a telescopic rod. However, considering the application scenarios of agricultural machinery, there is often no additional power to be supplied to the motor, and the motor has a shorter service life when working in such a dusty environment. Therefore, the above-mentioned solution is preferred.

[0027] In one embodiment, the reset component 6 includes a first upright 61 disposed on the fixed plate 1, a first pulley 62 rotatably disposed on the first upright 61, and a lifting platform 63 disposed below the first pulley 62. The bottom of the lifting platform 63 is provided with a rolling element 64 passing through the fixed plate 1. The rolling element 64 is used to contact the ground and moves downward when the fixed plate 1 is raised. It also includes a first traction rope 65, which passes around the first pulley 62 and is connected to the lifting platform 63 and the slider 51, and is used to drive the slider 51 to slide into the cavity when the fixed plate 1 is lifted.

[0028] In specific implementation, a through groove is provided on the fixed plate 1 along its traveling direction. One end of the through groove is connected to the chamber, and the other end extends towards the first pulley 62 and passes through the top of the fixed plate 1. The first traction rope 65 passes around the first pulley 62 and enters the through groove, extending along the through groove into the chamber and connecting with the slider 51. When the fixed plate 1 is lifted (i.e. when a row of drip irrigation tape is laid), the lifting platform 63 moves downward, driving the slider 51 to slide into the interior of the chamber for resetting.

[0029] In one embodiment, a spring 66 is provided between the lifting platform 63 and the fixed plate 1. The spring 66 is used to drive the lifting platform 63 downward when the fixed plate 1 is raised. A counterweight 67 is also provided on the lifting platform 63 to increase the load for the downward movement of the lifting platform 63. This design ensures that the lifting platform 63 has sufficient force to drive the corresponding traction rope when it moves downward. Preferably, the counterweight 67 is fixed to the lifting platform 63.

[0030] In one embodiment, a shearing component 7 is also included. The shearing component 7 is disposed at the tail end of the traveling direction of the fixed plate 1 and located behind the pressing component 5. The fixed plate 1 is provided with a relief groove 14 for the pressing component 5 to extend and retract at the position between the shearing component 7 and the pressing component 5. The fixed plate 1 is also provided with a through groove 15 at the position of the shearing component 7. The shearing component 7 includes a movable block 71 disposed at the through groove 15. The bottom of the movable block 71 can extend out of the through groove 15 to the bottom of the fixed plate 1. It also includes two shearing blades 72. The top ends of the two shearing blades 72 are rotatably connected to the bottom of the movable block 71, and a second torsion spring (not shown in the figure) is disposed between the two shearing blades 72. The second torsion spring is used to keep the bottoms of the two shearing blades 72 away from each other. The two shearing blades 72 cooperate with each other to shear the material. It also includes a lifting connector, one end of which is connected to the lifting platform 63 and the other end of which is connected to the moving block 71. When the lifting platform 63 moves downward, it drives the moving block 71 to move upward. When the moving block 71 moves upward, it drives the two shearing blades 72 to move upward together. Under the limitation of the through groove 15, the two shearing blades 72 approach each other to form a shearing action until the top of the two shearing blades 72 passes through the through groove 15.

[0031] In practice, when the agricultural machinery moves to the end of the slope, the drip irrigation tape needs to be cut, the fixing plate 1 needs to be lifted, and then the direction needs to be turned around to lay the drip irrigation tape again on another ridge of slope. In the existing technology, the drip irrigation tape is cut manually. However, in this application, the agricultural machinery only needs to continue to move a distance (since there is no slope here, the ditching component 2 is empty and will not damage the soil). Since one end of the drip irrigation tape is still buried in the soil, the drip irrigation tape will continue to unwind under tension. At this time, the exposed drip irrigation tape will pass through the shearing component 7 behind it, and then the agricultural machinery will lift the fixing plate 1. The lifting of the fixing plate 1 causes the lifting platform 63 to descend, and the two shearing blades 72 come together to form a shearing action to cut the drip irrigation tape.

[0032] It should be noted that the shearing blade 72 in the open state is attached to the slope, and is limited by the slope, so there is no need to worry that the exposed drip tape will start to move before the shearing component 7 reaches it.

[0033] Preferably, the bottom of the through groove 15 is chamfered to guide the two shearing blades 72 to gradually approach each other.

[0034] In one embodiment, the lifting connector includes a second upright 73 disposed on the fixed plate 1, the second upright 73 being located at the through groove 15, a second pulley 74 disposed on the second upright 73, a second traction rope 75, and a third pulley 68 disposed on the first upright 61. The second traction rope 75 passes around the second pulley 74 and the third pulley 68, and its two ends are connected to the lifting platform 63 and the moving block 71, for driving the moving block 71 to move upward when the fixed plate 1 is lifted.

[0035] In one embodiment, a connecting rod 731 is provided on the second upright 73, and a second pulley 74 is rotatably mounted on the connecting rod 731. A fourth pulley 76 is rotatably mounted on the top of the movable block 71. One end of the second traction rope 75 is fixed relative to the connecting rod 731. The second traction rope 75 passes around the fourth pulley 76 and the second pulley 74 to form a pulley group. The fourth pulley 76 is the movable pulley in the pulley group, and the second pulley 74 is the fixed pulley in the pulley group; thereby achieving the purpose of saving effort.

[0036] It should be noted that by adjusting the lengths of the first traction rope 65 and the second traction rope 75, the pressure plate 52 can be reset after the shearing component 7 cuts.

[0037] In one embodiment, the trenching component 2 is a wedge-shaped block, with one end away from the unwinding component 3 being triangular and used to break the soil to form a pre-buried trench. The bottom of the wedge-shaped block is a flat surface, and a rotating cavity 21 is also provided at the bottom of the wedge-shaped block. A ground roller is rotatably arranged in the rotating cavity 21. The ground roller has multiple ground teeth 641, which can extend out of the rotating cavity 21 to the bottom of the wedge-shaped block and contact the bottom surface of the pre-buried trench. The ground roller can rotate synchronously with the movement of the wedge-shaped block to loosen the soil at the bottom of the pre-buried trench. The bottom of the lifting platform 63 extends into the rotating cavity 21, and the ground roller also serves as a rolling component 64, which is rotatably installed at the bottom of the lifting platform 63.

[0038] In practice, the wedge-shaped section with a triangular face for breaking the soil has excellent flow conductivity, effectively reducing resistance and ensuring smooth operation during trenching. Simultaneously, setting the bottom of the wedge as a flat plane creates a wider and flat trench bottom, facilitating accurate drip irrigation tape installation. However, this method of extruding and breaking the soil can cause soil compaction at the trench bottom, affecting water infiltration (severe compaction can lead to water accumulation in the trench, with large amounts eventually overflowing the top and flowing down the slope, resulting in incomplete irrigation and poor water retention). Therefore, the design of the rolling ridge loosens the soil at the trench bottom, accelerating water infiltration and allowing water to quickly penetrate the seed rows for irrigation. At the same time, the rolling ridge is integrated with the lifting platform 63, which applies downward pressure to the rolling ridge, allowing it to rise and fall with the bottom of the trench.

[0039] Preferably, the rolling ridge is cylindrical in shape, and the rolling teeth 641 are distributed on the circumferential surface of the cylindrical shape; of course, the rolling teeth 641 can have various forms, such as being distributed on the circumferential surface of the cylindrical shape in the form of cylinders; the rolling teeth 641 can also be in the shape of a toothed disc, with a cylindrical outer surface coaxially arranged.

[0040] Preferably, the wedge-shaped block has a guide hole 22 inside, with one end of the guide hole 22 facing the fixing plate 1 and the other end facing the unwinding component 3. The fixing plate 1 has a clearance hole 12 at the corresponding position of the guide hole 22. One end of the drip irrigation tape passes through the clearance hole 12 and the guide hole 22 from top to bottom and enters the unwinding component 3. Of course, the drip irrigation tape can also be directly inserted into the opening on the fixing plate 1, so that one end of the drip irrigation tape enters the unwinding component 3.

[0041] In one embodiment, the power component can be a motor. However, considering the application scenario of this application, there is often no additional power supply to the motor, and the motor has a short service life when operating in a dusty environment. Therefore, the following solution can be adopted: The power unit includes a power shaft 32 rotatably mounted at the bottom of the fixed plate 1. The power shaft 32 is arranged parallel to two rotating shafts 31. A first gear 33 is provided on the power shaft 32. A second gear 34 that meshes with the first gear 33 is provided on the rotating shaft 31 near the power shaft 32. At least one end of the power shaft 32 is provided with a rotating wheel 35, which is used to contact the ground and drive the power shaft 32 to rotate during the movement. The linear velocity of the rotating wheel 35 (i.e., the distance swept by a point on the outer surface of the rotating wheel 35 per unit time) is equal to the linear velocity of the outer surface of the rotating shaft 31 (i.e., the distance swept by a point on the outer surface of the rotating shaft 31 per unit time).

[0042] Preferably, the rotating wheel 35 is located at both ends of the power shaft 32, and the outside of the rotating wheel 35 is provided with insert teeth 351 that contact the ground and can be inserted into the soil. This design not only avoids the rotating wheel 35 from slipping, but also makes it suitable for uneven ground and prevents it from being suspended in the air.

[0043] Preferably, the bottom of the fixing plate 1 is provided with two mounting plates 11, the two ends of the power shaft 32 and the two rotating shafts 31 are respectively rotatably disposed between the two mounting plates 11, the rotating wheel 35 is located on the side of the two mounting plates 11 that are far apart from each other, and the end of the power shaft 32 passes through the mounting plate 11 and is connected to the corresponding rotating wheel 35. Of the two rotating shafts 31, the rotating shaft 31 furthest from the power shaft 32 is fitted with a rotating cylinder 36. Both ends of the rotating shaft 31 extend out of the mounting plate 11 and rotating wheels 35 are also installed on the side of the mounting plate 11 that is far apart from each other. Furthermore, a transmission assembly 37 is provided between the power shaft 32 and the two rotating wheels 35 on the same side of the rotating shaft 31 to make the two rotating wheels on the same side rotate synchronously.

[0044] In practice, by also setting rotating wheels 35 at both ends of the rotating shaft 31 and making the two rotating wheels on the same side rotate synchronously, the rotating wheel 35 on the power shaft 32 can assist the power shaft 32 to rotate when it is suspended and cannot rotate (such as when encountering a small pit), thereby improving the equipment's obstacle-crossing ability.

[0045] It should be added that the two rotating wheels 35 on the same side do not interfere with each other and rotate synchronously only through the transmission assembly 37.

[0046] Preferably, the transmission assembly 37 can be a chain drive assembly including two sprockets and a chain, or a belt drive assembly including two pulleys and a drive belt, wherein the two sprockets or two pulleys are coaxially mounted with two rotating wheels on the same side.

[0047] Preferably, by roughening the surfaces of the rotating shaft 31 and the rotating drum 36, the friction is increased, preventing the rotating shaft 31 and the rotating drum 36 from slipping relative to the drip irrigation tape. There are many ways to roughen the surfaces of the rotating shaft 31 and the rotating drum 36. For example, a textured pattern can be rolled onto the outer surface, or a rubber sleeve with good friction performance can be fitted onto the outside of the rotating shaft 31 and the rotating drum 36. There are many methods, and no specific limitation is made here.

[0048] Preferably, it also includes a soil covering component 4, which is disposed at the bottom of the fixing plate 1 and located on the side of the fixing plate 1 away from the trench component 2. The soil covering component 4 includes two soil covering plates 41 distributed in a figure-eight shape, with the outwardly flared side of the figure-eight facing the unwinding component 3. The soil covering plate 41 is provided with a plurality of scraping teeth 42 on the side of the soil corresponding to the soil. The soil covering plate 41 scrapes out soil fragments at the top of the slope through the scraping teeth 42, and covers the drip irrigation tape with soil through the soil fragments during the process of moving.

[0049] In practice, since the ridge-forming method of the slope is achieved through compression molding by an inclined wheel, the surface of the slope is compacted. If a traditional soil-covering board 41 structure is used for soil covering, it is easy to run out of soil (because there is no broken soil, it is compacted during the slope shaping process). If a regular scraper tooth 42 is set directly opposite the trenching component 2, even if soil can be covered, the surface soil of the slope is compacted, and the scraped bumps are large. This not only easily breaks the shape of the slope, but also easily blocks large soil clods at the bottom of the fixing plate 1, increasing the burden on the farm. The energy consumption of the machine may even force the agricultural machine to stop or break the soil covering plate 41; however, the soil covering plate 41 with the "eight" shape distribution adopted in this application can discharge any excess soil from the "eight" shape opening, making it less likely to damage the "eight" shape. Moreover, the soil is scraped from both sides at an angle, so the soil on one side is relatively less stressed and the overall disturbance is small. Since the soil covering plate 41 with the "eight" shape distribution moves at an angle during the movement, it is not easy to form large protrusions. The protrusions cover the drip irrigation tape in a fragmented manner, which is more comprehensive and less likely to expose the drip irrigation tape.

[0050] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0051] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0052] Additionally, "multiple" refers to two or more.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
