[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0031] Reference Figure 1 、 Figure 3 and Figure 4 The utility model provides an embodiment: a vegetable planting mulching tool, including a pull rod 1. The pull rod 1 is the support and control component of the entire tool, made of aluminum alloy, lightweight and not easily deformed by pressure. The pull rod 1 is used to operate and push the entire tool, and is fixedly connected to the subsequent components by threaded welding to ensure stability. The lower end of the pull rod 1 is fixedly connected to a movable frame 2. The movable frame 2 is the part connected to the pull rod 1. It can flexibly adjust the degree of inclination through the subsequent components. It is suitable for users of different heights and arm lengths, and can make the pull rod 1 turn to the appropriate angle, which is convenient and labor-saving. The bottom end of the movable frame 2 is fixedly connected to a gear block 3. The gear block 3 is the core part of the angle adjustment component. Its gears are engaged with the subsequent components. When they are closed together, they will not rotate. They are used to fix the angle and can flexibly adjust the angle after separation. This design is to facilitate the operation of the tool.
[0032] A hole is formed on the inner side of tooth block 1 (3), into which a through-rod (5) is slidably connected. As an important component connecting tooth block 1 (3) and subsequent components, through-rod (5) limits the rotational range of tooth block 1 (3) and subsequent components, providing and transmitting the force used to close and open the gears. One end of through-rod (5) is fixedly connected to a limit assembly, and a tooth block (2) (4) is slidably connected to the outer side of through-rod (5). Tooth block (2) (4) is located on the inner side of the two tooth blocks (3) and meshes with them. The interaction between these structures can effectively drive the different functions of the tool, such as adjusting the tool depth or pushing and pulling subsequent components. The outer side of tooth block (2) (4) meshes with the outer side of tooth block (3), while the inner side of tooth block (2) (4) slides on the outer side of through-rod (5). The top of through-rod (5) is formed with a hole, into which a rotating shaft (1) (6) is rotatably connected. Rotating shaft (1) (6) is used to limit the rotational space of the subsequent components, allowing them to rotate flexibly.
[0033] The outer side of shaft 1 (6) is rotatably connected to a wrench 7, which is used to control the opening and closing of tooth block 1 (3) and tooth block 2 (4). Eccentric holes are provided on either side of the wrench 7, and shaft 1 (6) rotates in these eccentric holes. When wrench 7 is turned horizontally, tooth block 1 (3) separates from tooth block 2 (4) under the action of elastic force, facilitating adjustment of the angle of pull rod 1. When wrench 7 is turned vertically, its eccentric design causes tooth block 1 (3) to be pressed downward, causing tooth block 1 (3) to engage with tooth block 2 (4), fixing the angle of pull rod 1 for subsequent use. The inner side of wrench 7 is rotatably connected to the outer side of through-rod 5. An extension block 9 is fixedly connected to the outer side of tooth block 2 (4). Extension block 9 separates the angle adjustment assembly from subsequent components, preventing damage to subsequent components during rotation. A frame 10 is fixedly connected to the outer side of extension block 9. Frame 10 is the external structure of the entire tool, made of steel or high-strength plastic, and is used to support the rest of the device. Frame 10 is provided with multiple holes or slots for mounting subsequent components.
[0034] The limiting assembly includes a limiting block 8, which is a limiting assembly of the through rod 5 to prevent the through rod 5 from excessive movement or deviating from the designed track. The limiting block 8 is connected to the through rod 5 by a fixing screw or a slot to ensure that it can be maintained stably during operation. The outer side of the limiting block 8 is fixedly connected to the top of the through rod 5, the top of the through rod 5 is fixedly connected to the outer side of the limiting block 8, the outer side of the through rod 5 is slidably connected to the inner side of the tooth block 1 3, and the outer side of the through rod 5 is slidably connected to the inner side of the tooth block 2 4. The limiting assembly is used to limit the opening and closing angle of the tooth block 1 3 after the wrench 7 is opened, and can press the tooth block 1 3 when the wrench 7 is closed to prevent it from bouncing open and losing the adjustment function.
[0035] Reference Figures 1 to 3 A sizing rod 11 is fixedly connected to the inside of the frame 10. This sizing rod 11 serves to orient and support the frame 10, maintaining the tool's structural stability and preventing deformation or loosening of the frame 10 during use. A hole is provided at the bottom end of the frame 10. A second shaft 12 is rotatably connected to the hole in the frame 10. The second shaft 12 is used to rotate subsequent components thereon. Its smooth rotation enables subsequent components to rotate at the required rate. The outer side of the second shaft 12 is rotatably connected to the inner side of the hole in the frame 10.
[0036] The outer side of the second rotating shaft 12 is covered with a ground film 13. Ground film 13, an important material in vegetable cultivation, is arranged in a roll. Ground film 13 can be installed on the second rotating shaft 12, rotating it along with the second rotating shaft 12, and unrolling the ground film 13. The inner side of ground film 13 is rotatably connected to the outer side of the second rotating shaft 12. The inner side of the short rods at the bottom of the frame 10 is rotatably connected to the guide shaft 14. The ground film 13 passes between the two guide shafts 14, which can ensure that the ground film 13 is rolled out in the correct direction and avoid curling, entanglement, and tearing during the unrolling process. The outer side of the guide shaft 14 is rotatably connected to the inner side of the short rods at the bottom of the two frames 10.
[0037] The bottom of the frame 10 is fixedly connected to a fixing rod 15, which is used to carry and store subsequent height adjustment components, so that the internal components can move flexibly and provide certain mechanical support. A groove is provided on the inner side of the fixing rod 15, and a limit plate 16 is fixedly connected to the groove of the fixing rod 15. The limit plate 16 is used to limit the movement distance and direction of the subsequent components in the fixing rod 15, and can prevent the components therein from falling. The inner side of the limit plate 16 is rotatably connected to a bevel gear 18, which is used to change the horizontal rotational force into a longitudinal rotational force, so that the subsequent components run more smoothly, and its transmission is smooth and efficient, with high stability. The outer side of the bevel gear 18 is meshedly connected to a bevel gear 2 19, which is used to transmit force to the subsequent components. Its material is strong, there is little noise during rotation, and the transmission is smooth. The bottom of the bevel gear 18 is fixedly connected with a threaded rod 17. The rotation of the threaded rod 17 is used to adjust the height of the subsequent components. It is limited by the limiting plate 16 to rotate within the fixed rod 15. It is flexible and not stuck, so that the height adjustment is accurate and not prone to damage. The threaded rod 17 and the bottom of the threaded rod 17 are fixedly connected with a bottom block 20. The bottom block 20 is used for buffering and vibration reduction, and its diameter is larger than the subsequent components, which plays a limiting role to prevent excessive height adjustment from damaging the machine.
[0038] The outer side of threaded rod 17 is threadedly connected to movable rod 22, a core component of the height adjustment assembly. Its top end is threaded, allowing it to rise or fall as threaded rod 17 rotates. The aperture at its top end is smaller than the diameter of base block 20, limiting its range of motion and preventing damage to the machine from excessive adjustment. The outer side of movable rod 22 is slidably connected to the inner side of fixed rod 15, while the outer side of base block 20 is slidably connected to the inner side of movable rod 22.
[0039] The bottom of the movable rod 22 is rotatably connected to a rotating shaft 3 23, which can connect the movable rod 22 and subsequent components so that the subsequent components can drive it to rotate. The outer side of the rotating shaft 3 23 is fixedly connected to a film pressing wheel 24. The distance between the two film pressing wheels 24 is less than the length of the ground film 13. The excess parts on both sides of the ground film 13 can be pressed into the soil, so that the ground film 13 is fixed and prevented from being blown away by the wind. The effect is significant. In addition, the surface of the film pressing wheel 24 is smooth and has no sharp spots. It is not easy to scratch the ground film 13 and cause loss and waste. The rear side of the bevel gear 2 19 is fixedly connected to a turntable 21. The turntable 21 can control the rotation of the bevel gear 2 19. It can be manually rotated to accurately control the adjustment of the height adjustment component. The outer side of the turntable 21 is rotatably connected to the top hole of the fixed rod 15.
[0040] The frame 10 is connected to a toothed tire 25 for rotation. The toothed tire 25 can bear weight and is located at the bottom of the frame 10, driving the entire frame 10 and the components above it to move. The surface of the tire has teeth, and the soil where the tire passes will be dug by the teeth, making the soil soft, making it easier for the subsequent film pressing wheel 24 to press the ground film 13 into the soil, and can prevent the ground film 13 from being scratched by unbroken soil blocks, reducing the loss of the ground film 13. The outer side of the toothed tire 25 is rotatably connected to the inner side of the bottom of the frame 10, and the top of the fixing rod 15 is fixedly connected to the bottom of the frame 10.
[0041] Working principle: When it is necessary to cover the vegetables with ground film 13, first bend the wrench 7 to the horizontal direction. At this time, the outward-opening tooth block 13 loses pressure and expands outward, so that tooth block 13 and tooth block 2 4 are separated. At this time, adjust the movable frame 2 and the pull rod 1 to a suitable angle, and bend the wrench 7 to the vertical direction. At this time, the eccentric design of the wrench 7 and the limit block 8 together press tooth block 1 3 to the middle, so that tooth block 2 4 and tooth block 1 3 are engaged and cannot rotate. At this time, the angle is fixed. Then turn the turntable 21 to rotate the bevel gear 2 19 and the bevel gear 1 18, driving the threaded rod 17 to start rotating, causing the movable rod 22 to start descending. According to the different water content and hardness of the land in different regions, adjust the film pressing wheel 24 to the appropriate downward pressing distance to facilitate subsequent downward pressing.
[0042] Then the ground film 13 is installed into the rotating shaft 2 12, and a section of the ground film 13 is pulled out so that it is clamped between the two guide shafts 14, and the two sides of the ground film 13 are pressed under the film pressing wheel 24, and the pulled section of the ground film 13 is pressed under the soil. At this time, the pull rod 1 is pulled, and the toothed tire 25 drives the device to start moving. The toothed tire 25 turns the soil during the movement, and then the two guide shafts 14 guide the ground film 13 out, and the film pressing wheel 24 presses the ground film 13 on both sides into the soft soil to complete the fixation.
[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
