Abstract
Description
Technical Field
[0001] This invention relates to the field of agricultural machinery and equipment technology, and in particular to a machine and method for laying, burying and cutting seed ropes, drip irrigation tapes and mulch films. Background Technology
[0002] The continuous decline in agricultural workers, high labor costs, and poor quality of traditional mechanized operations have become major challenges facing global agricultural development. With the development of agricultural mechanization and informatization technologies, key technologies in unmanned farms, such as automatic navigation, can significantly improve operational efficiency and reduce manual labor through mechanical information integration, resulting in substantial cost reduction and efficiency improvement. This has become a major development direction for current agricultural production. However, in unmanned planting operations for crops like cotton and radishes, manual labor is still required to follow the machinery, checking the condition of seed ropes / drip irrigation tapes and mulch film for timely replacement. Furthermore, when changing rows at the edge of the field, manual cutting and compaction of seed ropes / drip irrigation tapes and mulch film are also necessary. The poor working environment and high labor intensity make this a weak link in the mechanized planting of cotton and radishes, hindering the development of unmanned farms. Summary of the Invention

[0007] According to the present invention, a tool for laying, burying, and cutting seed ropes, drip irrigation tapes, and mulch films is provided. The first cutting mechanism includes: a first transmission assembly connected to the ground wheel; a first connecting rod, the first end of which is hinged to the first transmission assembly; a push rod, the first end of which is hinged to the second end of the first connecting rod, which can reciprocate in a straight line under the drive of the first transmission assembly; a guide tube, in which the seed rope or the drip irrigation tape passes, and the second end of the push rod is inserted into the guide tube, which can push the seed rope or the drip irrigation tape downwards during the reciprocating motion; a second transmission assembly; and a first cutter connected to the second transmission assembly via an iris mechanism, wherein the second transmission assembly drives the first cutter to rotate in order to cut the seed rope or the drip irrigation tape.
[0008] According to the present invention, a tool for laying, burying, and cutting seed ropes, drip irrigation tapes, and mulch films is provided. The second end of the push rod is provided with a flexible plug, which has a switchable expanded state and a contracted state. When the push rod moves in the direction of extending into the guide tube, the flexible plug is in the expanded state to increase the contact area with the seed rope or the drip irrigation tape. When the push rod moves in the direction of withdrawing from the guide tube, the flexible plug is in the contracted state to reduce the contact area with the seed rope or the drip irrigation tape.
[0009] According to the present invention, a tool for laying, burying, and cutting seed ropes, drip irrigation tapes, and mulch films is provided. The second cutting mechanism includes: a rack; a first gear, which is connected to the ground wheel for transmission, and a portion of the circumferential surface of the first gear is provided with teeth; a first rolling rod and a second rolling rod, the first rolling rod and the second rolling rod being arranged opposite to each other, the shaft of the first rolling rod being connected to the rack, and the first rolling rod being rotatable; wherein, the rack has a switchable downward movement state and an upward movement state.

Detailed Implementation
[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.
[0027] The terms "first" and "second" in the specification and claims of this invention may explicitly or implicitly include one or more of those features. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.
[0028] The following is combined Figures 1-8 The present invention describes the tools and methods for laying, burying, and cutting seed ropes, drip irrigation tapes, and mulch films.
[0029] like Figure 1 As shown in the embodiment of the present invention, the equipment for laying, burying, and cutting seed ropes, drip irrigation tape, and mulch film includes: a frame 1, a first conveying mechanism 2, ground wheels 3, a second conveying mechanism 8, a pre-burying mechanism 7, and a cutting mechanism. The frame 1 is equipped with multiple ground wheels 3, and the first conveying mechanism 2, the second conveying mechanism 8, the pre-burying mechanism 7, and the cutting mechanism are all mounted on the frame 1. The first conveying mechanism 2 is equipped with a monitor 202, which monitors the remaining amount of seed ropes and drip irrigation tape. The second conveying mechanism 8 is used to convey mulch film 505 and monitor its remaining amount. The pre-burying mechanism 7 is used to bury the mulch film 505, and the cutting mechanism is used to cut the seed ropes, drip irrigation tape, and mulch film 505. The ground wheels 3 are connected to the first conveying mechanism 2, the second conveying mechanism 8, the pre-burying mechanism 7, and the cutting mechanism.
[0030] Specifically, multiple ground wheels 3 are evenly distributed at the lower part of the frame 1 and are connected to the first conveying mechanism 2, the second conveying mechanism 8, the pre-embedding mechanism 7, and the cutting mechanism via chain / belt transmission. The corresponding mechanisms are driven by ground friction rotation. The first conveying mechanism 2 is used to set the seed rope reel and drip irrigation tape reel. When the seed rope reel and drip irrigation tape reel rotate, the seed rope and drip irrigation tape can be laid on the ground. The second conveying mechanism 8 is used to install the mulch film reel. When the mulch film reel rotates, it can lay the mulch film 505 on the ground. The pre-embedding mechanism 7 is used to bury the mulch film 505 in the soil. When the machine reaches the end of the field, the cutting mechanism cuts the seed rope, drip irrigation tape, and mulch film 505. Then, the machine turns around and starts laying the seed rope, drip irrigation tape, and mulch film 505 again.
[0031] Specifically, when the ground wheel 3 rotates, the seed rope reel, drip irrigation tape reel, and mulch film reel rotate to lay the seed rope, drip irrigation tape, and mulch film 505 on the ground. The pre-burying mechanism 7 buries the mulch film 505 in the soil. When the machine travels to the end of the field, the cutting mechanism cuts the seed rope, drip irrigation tape, and mulch film 505.
[0032] Furthermore, in an embodiment of the present invention, the monitor 202 is disposed on the first conveying mechanism 2. The monitor 202 is used to monitor the remaining amount of the seed rope and drip irrigation tape. When the remaining amount of both is less than a preset value, the monitor 202 sends a signal to the host computer, which then issues an alarm to remind the staff to replace the seed rope and drip irrigation tape. Optionally, in an embodiment of the present invention, the monitor 202 can be a snap ring, a photoelectric sensor, an ultrasonic sensor, or a torque sensor, etc. Furthermore, when the data detected by the monitor 202 changes very little or fluctuates within a period of time, it can be considered that a blockage has occurred. At this time, the monitor 202 also sends a signal to the host computer, which will also issue an alarm to remind the staff to carry out timely maintenance.
[0033] Furthermore, the second conveying mechanism 8 includes a strain gauge 801 and a mulch film shaft 802. The mulch film disc is sleeved outside the mulch film shaft 802 and can rotate freely. The strain gauge 801 is used to detect the deformation of the mulch film shaft 802. By detecting the deformation of the mulch film shaft 802, the weight of the mulch film 505 is indirectly measured. When the deformation of the mulch film shaft 802 is small, the allowance of the mulch film 505 is small. When the allowance of the mulch film 505 is less than a preset value, the strain gauge 801 sends a signal to the host computer, and the host computer issues an alarm. In addition, a bearing can be installed on the mulch film shaft 802 to reduce the friction between the mulch film disc and the mulch film shaft 802.
[0034] It should be noted that, in the embodiments of the present invention, agricultural materials include: seed ropes, drip irrigation tapes, and mulch films, etc.
[0035] The equipment for laying, burying, and cutting seed ropes, drip irrigation tapes, and mulch film provided in this invention embodiment, by setting up a monitor, realizes real-time monitoring of the remaining amount of seed ropes, drip irrigation tapes, and mulch film, as well as alarms for insufficient seed ropes and drip irrigation tapes during mechanical sowing operations such as cotton and radish planting. By setting up a first conveying mechanism, a second conveying mechanism, a pre-burying mechanism, and a cutting mechanism, the equipment can automatically lay and bury seed ropes, drip irrigation tapes, and mulch film. When the equipment reaches the end of the field, it can automatically cut the seed ropes, drip irrigation tapes, and mulch film, effectively solving the problems of poor working environment and high labor intensity caused by manual following of the equipment for burying and cutting. It improves work efficiency, reduces labor input, and enhances the level of unmanned operation in farms.
[0036] like Figure 1 As shown, in an embodiment of the present invention, the first conveying mechanism 2 includes multiple pairs of supports 201, which are arranged in parallel on the frame 1. One support 201 in each pair of supports 201 is used to set the seed rope reel, and the other support 201 is used to set the drip irrigation tape reel. The seed rope reel and the drip irrigation tape reel can rotate freely to lay the seed rope and drip irrigation tape on the ground. Each support 201 is provided with a monitor 202.
[0037] Specifically, the support frame 201 is located at the front of the machine. The seed rope reel support 201 and the drip irrigation tape reel support 201 are installed in pairs on the top of the frame 1 and can rotate independently of each other, enabling automatic retraction and extension of the seed rope and drip irrigation tape. Each support frame 201 is equipped with a monitor 202 to monitor the remaining amount of seed rope or drip irrigation tape.
[0038] Furthermore, a bearing 203 can be added to the bracket 201 to reduce the damping between the seed rope reel, the drip irrigation tape reel and the shaft, so that the seed rope reel and the drip irrigation tape reel can discharge material smoothly and the material tape can be extruded easily.
[0039] Optionally, bearing 203 can also be replaced with a damping bearing or a damping shaft can be installed between the spacers of each seed rope reel and drip irrigation tape reel. Without affecting the relative rotation of the seed rope reel and drip irrigation tape reel, the forward momentum can be recovered through the damping bearing or damping shaft as the power source for the auxiliary rotation of the material belt.
[0040] like Figure 1 As shown, in an embodiment of the present invention, the cutting mechanism includes: a first cutting mechanism 4 and a second cutting mechanism 5. The first cutting mechanism 4 is used to push the seed rope and drip irrigation tape downwards so that the seed rope and drip irrigation tape are laid on the ground. The first cutting mechanism 4 is also used to cut the seed rope and drip irrigation tape. The second cutting mechanism 5 is used to pull the mulch film 505 so that the mulch film 505 is laid on the ground. The second cutting mechanism 5 is also used to cut the mulch film 505.
[0041] like Figure 2 As shown, in an embodiment of the present invention, the first cutting mechanism 4 includes: a first transmission assembly, a first connecting rod 404, a push rod 405, a guide tube 410, a second transmission assembly, and a first cutter 407. The first transmission assembly is connected to the ground wheel 3. The two ends of the first connecting rod 404 are respectively hinged to the first transmission assembly and the first end of the push rod 405. Under the drive of the first transmission assembly, the push rod 405 can reciprocate in a straight line. The seed rope or drip irrigation tape is inserted into the guide tube 410, and the second end of the push rod 405 is inserted into the guide tube 410. When the push rod 405 reciprocates, it can push the seed rope or drip irrigation tape downward. The first cutter 407 is connected to the second transmission assembly by an iris mechanism. The second transmission assembly is used to drive the first cutter 407 to rotate in order to cut the seed rope or drip irrigation tape.
[0042] Specifically, the number of first cutting mechanisms 4 is equal to the number of supports 201. Each first cutting mechanism 4 is used to push, pull, and cut the seed rope or drip irrigation tape on a support 201. Specifically, the first transmission assembly includes: a second turntable 401, a synchronous belt 402, and a third turntable 403. The second turntable 401 and the third turntable 403 are connected by the synchronous belt 402. The third turntable 403 is provided with a boss. The two ends of the first connecting rod 404 are respectively hinged to the boss and the first end of the push rod 405. When the ground wheel 3 rotates, it drives the third turntable 403 to rotate, which in turn drives the first connecting rod 404 to rock, so that the push rod 405 can reciprocate linearly along the guide tube 410.
[0043] In this embodiment, the guide tube 410 includes a first tube body and a second tube body. The first tube body and the second tube body are inclined and connected. The seed rope / drip irrigation tape 411 is inserted into the first tube body. The second end of the push rod 405 is inserted into the second tube body. When the push rod 405 moves in the direction of extending into the second tube body, the push rod 405 abuts against the seed rope / drip irrigation tape 411 and pushes the seed rope / drip irrigation tape 411 downward so that the seed rope / drip irrigation tape 411 is laid on the ground. When the push rod 405 moves in the direction of withdrawing from the second tube body, the push rod 405 separates from the seed rope / drip irrigation tape 411.
[0044] Furthermore, such as Figure 3 As shown, the second end of the push rod 405 is provided with a flexible plug, which has a switchable expanded state and a contracted state. When the push rod 405 moves in the direction of extending into the guide tube 410, the flexible plug is in the expanded state and contacts the seed rope / drip tape 411 to push the seed rope / drip tape 411 downward. When the push rod 405 moves in the direction of withdrawing from the guide tube 410, the flexible plug is in the contracted state.
[0045] Specifically, the flexible plug is made of flexible material and has a concave end face. When the flexible plug is in an expanded state, its contact area with the seed rope / drip tape 411 increases, and the friction increases, which makes it easier to push the seed rope / drip tape 411. When the push rod 405 moves in the direction of withdrawing from the inside of the guide tube 410, the flexible plug is in a contracted state, and its contact area with the seed rope / drip tape 411 decreases, which enables the push rod 405 to retract quickly.
[0046] Furthermore, such as Figure 2As shown, the second transmission assembly includes an outer gear 406, a second gear 408, and a first motor 409. The first motor 409 drives the second gear 408 to rotate, and the second gear 408 meshes with the outer gear 406, thereby driving the outer gear 406 to rotate. The outer gear 406 is connected to the first cutter 407 via an iris mechanism. The first cutter 407 includes multiple blades arranged in a spiral pattern. When the first cutter 407 rotates, the multiple blades can converge to cut the seed rope / drip tape 411 or separate from each other. Specifically, when the outer gear 406 rotates, there is a relative rotational motion between the outer gear 406 and the first cutter 407, and the multiple blades move in the direction of convergence, thereby cutting the seed rope / drip tape 411.
[0047] In actual operation, after each row of work is completed, the host computer sends a signal to make the first motor 409 drive the second gear 408 to rotate, which in turn drives the outer gear 406 and the first cutter 407 to rotate, so as to cut the seed rope / drip tape 411.
[0048] Furthermore, such as Figure 2 As shown, in an embodiment of the present invention, the first cutting mechanism 4 further includes a first synchronizing rod 413. The first synchronizing rod 413 is used to connect all the first connecting rods 404 in the plurality of first cutting mechanisms 4 in series to avoid the phenomenon of uneven rotation angles of the third turntable 403 caused by the offset of the machine body, thereby ensuring that the push rod 405 pushes out the seed rope / drip tape 411 at a consistent speed. Since the machine will inevitably slip on both sides when moving forward, resulting in uneven rotation angles of the third turntable 403, the first cutting mechanism 4 adopts belt drive. When the angle difference between the two sides of the third turntable 403 is too large, the belt drive will slip, thereby preventing the first synchronizing rod 413 from being overloaded and deformed.
[0049] Furthermore, the first cutting mechanism 4 also includes a track block 412. The first side of the track block 412 is connected to the frame 1, and the second side of the track block 412 is provided with a through groove. The push rod 405 passes through the through groove. When the first connecting rod 404 is rocked, the push rod 405 reciprocates in the through groove. The through groove plays a role in positioning the direction of movement of the push rod 405, so as to ensure that the push rod 405 can smoothly perform reciprocating linear motion in the guide tube 410.
[0050] Furthermore, the pushing speed of push rod 405 can be changed by adjusting the transmission ratio between the second turntable 401 and the third turntable 403.
[0051] The tool for laying, burying, and cutting seed ropes, drip irrigation tapes, and mulch film provided in this embodiment of the invention has a flexible plug at one end of the push rod. When the push rod is inserted into the guide tube, the flexible plug expands to increase the contact area with the seed rope or drip irrigation tape, thereby pushing the seed rope or drip irrigation tape to be laid on the ground. When the push rod is withdrawn from the guide tube, the flexible plug contracts to reduce the contact area with the seed rope or drip irrigation tape, thereby facilitating the retraction of the push rod.
[0052] like Figure 4 As shown, in an embodiment of the present invention, the second cutting mechanism 5 includes: a rack 513, a first gear 501, a first rolling rod 504, and a second rolling rod 506. The first gear 501 is connected to the ground wheel 3 for transmission. A portion of the circumferential surface of the first gear 501 is provided with teeth. The first rolling rod 504 and the second rolling rod 506 are arranged opposite to each other. The shaft of the first rolling rod 504 is connected to the rack 513, and the first rolling rod 504 can rotate. The rack 513 has a switchable downward movement state and an upward movement state. When the rack 513 is opposite to the toothless portion of the first gear 501, the rack 513 is in the downward movement state. The first rolling rod 504 and the second rolling rod 506 abut against each other to clamp the mulch film 505 between them. When the first rolling rod 504 rotates, it can drive the mulch film 505 to be laid on the ground. When the rack 513 meshes with the first gear 501, the rack 513 is in an upward motion state, and the first rolling rod 504 separates from the ground film 505.
[0053] Specifically, when the ground wheel 3 rotates, it drives the first gear 501 to rotate. During each row of operation, the toothless part of the first gear 501 is opposite to the rack 513. The rack 513 moves downward under the action of gravity, which in turn drives the first rolling rod 504 to move downward together, so that the mulch film 505 is sandwiched between the first rolling rod 504 and the second rolling rod 506. When the first rolling rod 504 rotates, it can pull the mulch film 505 to move, thus laying the mulch film 505 on the ground. After part of the mulch film 505 is buried, the first gear 501 continues to rotate, so that the toothed part of the first gear 501 meshes with the rack 513, which in turn drives the rack 513 to move upward, causing the first rolling rod 504 to separate from the second rolling rod 506, thereby reducing the resistance encountered when the mulch film 505 is naturally pulled out.
[0054] Furthermore, such as Figure 4 As shown, the second cutting mechanism 5 further includes a third transmission assembly and a second cutter 507. The second cutter 507 is connected to the third transmission assembly, which drives the second cutter 507 to reciprocate in order to cut the mulch film 505.
[0055] Specifically, the third transmission component includes: a first eccentric gear 509, a second eccentric gear 508, and a third eccentric gear 510. The first eccentric gear 509 is connected to the ground wheel 3. When the ground wheel 3 rotates, it drives the first eccentric gear 509 to rotate. The first eccentric gear 509 meshes with the second eccentric gear 508 and the third eccentric gear 510, thereby driving the second eccentric gear 508 and the third eccentric gear 510 to reciprocate up and down. The second eccentric gear 508 is connected to the second cutter 507, thereby driving the second cutter 507 to reciprocate up and down.
[0056] Specifically, each rotation of the first eccentric gear 509 enables a single lifting and lowering of the second cutter 507. At the end of each row of work, the second cutter 507 completes the film cutting action under the drive of the second eccentric gear 508 and the third eccentric gear 510, and is lifted upward after film cutting is completed.
[0057] Furthermore, in an embodiment of the present invention, the second cutting mechanism 5 further includes a drive shaft 503 and a belt 502. The first gear 501 is connected to the drive shaft 503 via the belt 502, and the drive shaft 503 is also connected to the first rolling rod 504 via a chain drive. When the ground wheel 3 rotates, the first gear 501 can drive the drive shaft 503 to rotate, thereby driving the first rolling rod 504 to rotate. Specifically, when the toothless part of the first gear 501 is opposite to the rack 513, the first rolling rod 504 and the second rolling rod 506 press the ground film 505 together, and at the same time, the first rolling rod 504 rotates to drag the ground film 505 out, thereby laying the ground film 505 on the ground.
[0058] Optionally, such as Figure 4 As shown, in one embodiment of the present invention, the second cutting mechanism 5 further includes a slide rail 511 and a guide rail 512. A first eccentric gear 509, a second eccentric gear 508, and a third eccentric gear 510 are mounted on the slide rail 511. The cutting cycle of the second cutter 507 can be changed by adjusting the transmission ratio between the eccentric gears to alter the rotational speed of the first eccentric gear 509. A faster rotational speed results in a shorter cutting cycle and a shorter length per row. Optionally, the first eccentric gear 509 can also be continuously variable in speed using electro-hydraulic or other drive methods. The guide rail 512 is mounted on the frame 1, and the rack 513 can slide up and down along the guide rail 512.
[0059] Optionally, such as Figure 5As shown, in another embodiment of the present invention, the second cutting mechanism 5 further includes a gearbox 514 and a guide rail 512. A first eccentric gear 509, a second eccentric gear 508, and a third eccentric gear 510 are mounted on the gearbox 514. The cutting cycle of the second cutter 507 can be changed by adjusting the transmission ratio between the eccentric gears within the gearbox 514 to alter the rotational speed of the first eccentric gear 509. A faster rotational speed results in a shorter cutting cycle and a shorter length per row. Optionally, the first eccentric gear 509 can also be continuously variable via electro-hydraulic or other drive methods, in which case the gearbox 514 is not required. The guide rail 512 is mounted on the frame 1, and the rack 513 can slide up and down along the guide rail 512.
[0060] Furthermore, the separation time between the first rolling rod 504 and the second rolling rod 506 can be adjusted in the following ways: First, by changing the transmission ratio between the first gear 501 and the ground wheel 3; Second, by changing the number of teeth or the pitch circle diameter of the first gear 501 and the rack 513; Third, by changing the length of the guide rail 512 to make the rack 513 travel longer.
[0061] The tool for laying, burying, and cutting seed ropes, drip irrigation tapes, and mulch film provided in this embodiment of the invention makes part of the circumferential surface of the first gear toothless. When the toothless part is opposite to the rack, the rack moves downward, thereby causing the two rolling rods to press the mulch film tightly and lay it. After part of the mulch film is buried, the first gear meshes with the rack, thereby causing the two rolling rods to separate, thus reducing the resistance when the mulch film is laid freely.
[0062] like Figure 6 As shown, in an embodiment of the present invention, the pre-embedded mechanism 7 includes: a first turntable 701, a second connecting rod 703, a pressure rod 707, and a sliding assembly. The first turntable 701 is drivenly connected to the ground wheel 3. The first end of the second connecting rod 703 is hinged to the first turntable 701, and the pressure rod 707 is hinged to the second end of the second connecting rod 703. The pressure rod 707 is connected to a pressing blade 706, which is used to press the mulch film 505 into the soil. The pressure rod 707 is slidably connected to the sliding assembly. When the first turntable 701 rotates, it can drive the pressure rod 707 to slide relative to the sliding assembly, so that the pressing blade 706 always presses against the same position of the mulch film 505 to press the mulch film 505 into the soil.
[0063] Specifically, when the ground wheel 3 rotates, it drives the first turntable 701 to rotate, which in turn drives the second connecting rod 703 to shake. The second connecting rod 703 pushes the pressure rod 707 to slide along the sliding assembly, so that the relative position of the pressing blade 706 and the mulch film 505 remains unchanged. The pressing blade 706 always presses against the same part of the mulch film 505 to press the mulch film 505 into the soil.
[0064] Furthermore, the sliding assembly includes: an elastic element 705, a slide rail 709, and a slider 708. The first end of the elastic element 705 is connected to the frame 1. The slide rail 709 is located on the frame. The first side of the slider 708 is connected to the pressure rod 707. The second side of the slider 708 is slidably connected to the slide rail 709. The third side of the slider 708 is connected to the second end of the elastic element 705. The first side is opposite to the second side, and the third side is adjacent to the first side. When the first turntable 701 rotates, the slider 708 can slide along the slide rail 709 under the drive of the second connecting rod 703, so that the pressing blade 706 always presses against the same position of the mulch film 505. The elastic element 705 is used to drive the slider 708 to reset.
[0065] Specifically, the slide rail 709 is provided with a transverse groove, along which the slider 708 can slide. Thus, when the machine moves, the pressure rod 707 slides horizontally, while the pressing blade 706 remains in the same position relative to the mulch film 505. In this embodiment, when the machine moves, the ground wheel 3 drives the first turntable 701 to rotate, which in turn drives the second connecting rod 703 to rock, thereby causing the pressure rod 707 to slide laterally along the slide rail 709. The pressing blade 706 presses the mulch film 505 into the soil. As the pressure rod 707 slides, the elastic element 705 extends. After the mulch film 505 is covered with soil, the pressing blade 706 rises. After the operation is completed, the elastic element 705 drives the slider 708 to return to its original position. During the operation, the pressing blade 706 periodically presses down to ensure close contact between the mulch film 505 and the soil.
[0066] Furthermore, in this embodiment, a boss is provided on the second side of the slider 708, and the boss is fixed in the slide rail 709. At this time, the mechanism composed of the second connecting rod 703, the pressure rod 707 and the sliding assembly is a crank-rocker mechanism. In this embodiment, the rotation of the slider 708 in the horizontal direction is not restricted. At this time, the operation of pressing down the mulch film 505 is less forceful than locking the rotation of the slider 708 in the horizontal direction, which is suitable for laying thinner mulch film 505.
[0067] like Figure 6 As shown, the pre-embedded mechanism 7 further includes: a fixing block 704, a rotating shaft 710, a second synchronizing rod 711, and a chain 702. The fixing block 704 is disposed on the frame 1 and is connected to one end of the elastic element 705. The first turntable 701 is provided with a rotating shaft 710, which is connected to the ground wheel 3 via the chain 702. In an embodiment of the present invention, there are two pre-embedded mechanisms 7, which are symmetrically arranged at the tail of the frame 1. The second synchronizing rod 711 is used to connect the second connecting rods 703 of the two pre-embedded mechanisms 7 in series to avoid the phenomenon of uneven rotation angles of the first turntable 701 caused by the offset of the machine body.
[0068] The equipment for laying, burying, and cutting seed ropes, drip irrigation tapes, and mulch film provided in this embodiment of the invention, by setting elastic elements, slides, and sliders, allows the pressing blade to periodically press the mulch film into the soil as the equipment moves, ensuring close contact between the mulch film and the soil, avoiding manual burying, and improving the operating efficiency of the equipment.
[0069] Furthermore, the equipment for laying, burying, and cutting seed ropes, drip irrigation tapes, and mulch film also includes a soil covering mechanism 6. The soil covering mechanism 6 includes a soil covering shovel 601 and an adjusting bracket 602. The adjusting bracket 602 is connected to the frame 1, and the soil covering shovel 601 is connected to the adjusting bracket 602. The adjusting bracket 602 is used to adjust the depth of the soil covering shovel 601 into the soil to control the amount of soil covering.
[0070] like Figure 7 As shown, this embodiment of the invention also provides a method for laying, burying, and cutting seed ropes, drip irrigation tapes, and mulch films using machinery, specifically including the following steps:
[0071] Step 101: Obtain real-time operating information of the equipment and plan the operating path of the equipment; Step 102: Control the first conveying mechanism 2 to convey the seed rope and drip irrigation tape, and control the second conveying mechanism 8 to convey the mulch film 505; Step 103: Control the pre-burying mechanism 7 to bury the mulch film 505; Step 104: Obtain the real-time position information of the equipment, and when the equipment reaches the end of the field, control the cutting mechanism to cut the seed rope, drip irrigation tape and mulch film 505. In the steps of controlling the first conveying mechanism to convey the seed rope and drip irrigation tape and controlling the second conveying mechanism to convey the mulch film, the method also includes: real-time monitoring of the amount of seed rope, drip irrigation tape and mulch film 505 used, and issuing an alarm when the remaining amount of seed rope, drip irrigation tape and mulch film 505 is less than the preset value or when the seed rope and drip irrigation tape are blocked.
[0072] Specifically, after the machinery enters the plot and travels a certain distance, a marker is set up at the edge of the plot. The host computer, based on a combination of GNSS, inertial navigation unit, and vision navigation, determines the position of the seeder and plans the operation route and method in real time according to the work prescription map, plot map, and planted crops. The first conveying mechanism 2 is controlled to rotate, delivering the seed rope / drip tape 411 and laying it on the ground; the second conveying mechanism 8 is controlled to rotate, delivering the mulch film 505 and laying it on the ground. The pre-burying mechanism 7 buries the mulch film 505 to ensure close contact between the mulch film 505 and the ground. When the machinery reaches the edge of the plot, the first cutter 407 of the first cutting mechanism 4 cuts the seed rope / drip tape 411, and the second cutter 507 of the second cutting mechanism 5 cuts the mulch film 505, thus completing the laying, burying, and cutting of one row of seed rope, drip tape, and mulch film 505.
[0073] Furthermore, during the laying of the seed rope, drip irrigation tape, and mulch film 505, the monitor 202 monitors the remaining amount of the seed rope / drip irrigation tape 411 in real time. When the remaining amount of the seed rope / drip irrigation tape 411 is less than a preset value, a signal is sent to the host computer, which issues an alarm. Simultaneously, when material blockage occurs, the monitor 202 also sends a signal to the host computer, which issues an alarm. The strain gauge 801 monitors the remaining material of the mulch film 505 in real time. When the remaining material of the mulch film 505 is less than a preset value, the strain gauge 801 sends a signal to the host computer, which issues an alarm.
[0074] The method for laying, burying, and cutting seed ropes, drip irrigation tapes, and mulch film provided in this invention enables real-time monitoring of the remaining amount of seed ropes, drip irrigation tapes, and mulch film, as well as material shortage alarms. By setting up a first conveying mechanism, a second conveying mechanism, a pre-burying mechanism, and a cutting mechanism, the seed ropes, drip irrigation tapes, and mulch film can be automatically laid and buried. During row changes, the seed ropes, drip irrigation tapes, and mulch film can be automatically cut, effectively solving the problems of poor working environment and high labor intensity caused by manual following of the burying and cutting of the machinery. This improves work efficiency, reduces manual input, and enhances the level of unmanned operation in farms.
[0075] The following combination Figure 8 This invention provides a detailed description of the working process of the equipment used for laying, burying, and cutting seed ropes, drip irrigation tapes, and mulch films according to embodiments of the present invention.
[0076] Connect the seeder to the tractor via frame 1. Before starting work, lower the implements to the field and move them a short distance to expel the seed rope, drip irrigation tape, and mulch film 505. Set up a marker at the edge of the field. The host computer uses a combination of GNSS, inertial navigation unit, and vision to determine the seeder's position and plans the work route and operation method in real time based on the work prescription map, plot map, and planted crops.
[0077] Monitor 202 monitors whether the remaining amount of seed rope and drip irrigation tape is sufficient and whether the extrusion is smooth. Strain gauge 801 monitors the remaining amount of mulch film 505. If there is sufficient remaining material and no blockage occurs, the operation begins. During operation, the operating speed of each mechanism depends on the tractor traction speed.
[0078] When the machine moves, the first gear 501 rotates so that the toothless part is opposite to the rack 513. The rack 513 and the first rolling rod 504 fall along the guide rail 512. The first rolling rod 504 abuts against the second rolling rod 506 to press the mulch film 505 tightly. The drive shaft 503 rotates to drive the first rolling rod 504 to rotate, so as to extrude the mulch film 505 and lay it on the ground.
[0079] During the movement, the first turntable 701 drives the second connecting rod 703 to shake, which in turn causes the pressing blade 706 to press the mulch film 505 into the soil. The slider 708 will continue to press down on the mulch film 505 within a certain angle that the first turntable 701 has rotated through, so as to ensure that the pressing blade 706 will remain in the original position and press down on the mulch film 505 when the vehicle moves forward. After the mulch film is covered with soil, the pressing blade 706 is raised. After a single pressing action is completed, the elastic element 705 fixed on the fixing block 704 is reset, which in turn drives the slider 708 to reset.
[0080] Simultaneously, the rotation of the third turntable 403 causes the first connecting rod 404 to shake, which in turn causes the push rod 405 to reciprocate linearly along the guide tube 410. When the flexible plug of the push rod 405 is in an expanded state, the flexible plug contacts the seed rope / drip irrigation tape 411, thereby pushing the seed rope / drip irrigation tape 411 downward to lay the seed rope / drip irrigation tape 411 and the mulch film 505 at the same time. If there is insufficient material or blockage occurs, the host computer sends a signal back to the cloud management platform and alarms, and the material tape is replaced or repaired manually. Once the material tape replacement or repair is completed, the operation continues.
[0081] The system determines whether the machine has reached the field. If not, the operation continues. If it has, the host computer sends a signal to the first motor 409, which drives the second gear 408 connected to it to rotate at a certain angle. The outer gear 406, which meshes with the second gear 408, rotates, causing the first cutter 407 to tighten inward and cut the seed rope / drip tape 411, causing it to fall to the ground. The second cutter 507, driven by the second eccentric gear 508 and the third eccentric gear 510, completes the film cutting action. After film cutting, it lifts up and begins to turn and change lanes. During the turning process, it completes the pre-extrusion work for the next row of work and lifts all mechanisms.
[0082] Determine if the turn and change of direction is complete. If not, continue to complete the turn. If the turn and change of direction is complete, all mechanisms will drop down and the above operation will be repeated.
[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
