Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and particularly relates to a ground film punching device. Background Art

[0002] The mulch film punching device is a device specially used to punch holes in the mulch film covering farmland. The main purpose of this device is to improve the air permeability of the soil by forming holes in the mulch film, promote the respiration and growth of crop roots, and also help the water and nutrients in the soil penetrate into the crop roots.

[0003] However, different crops have different requirements for soil permeability and root growth space. Traditional fixed-structure drilling devices may not be able to flexibly adjust the depth and density of drilling, making it difficult to meet the growth needs of diverse crops. Soil moisture, hardness and other conditions will affect the drilling effect. Traditional devices may not be able to be fine-tuned according to the actual soil conditions, resulting in unsatisfactory drilling results. Utility Model Content

[0025] 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.

[0026] like Figure 1 As shown;

[0027] A ground film punching device comprises a connecting plate 1.

[0028] In this embodiment: different crops have different requirements for soil permeability and root growth space. The traditional fixed-structure punching device may not be able to flexibly adjust the depth and density of the punching, and it is difficult to meet the growth needs of diverse crops. Soil moisture, hardness and other conditions will affect the punching effect. The traditional device may not be able to make fine adjustments according to the actual soil conditions, resulting in unsatisfactory punching results. In order to solve this technical problem, a punching component 2 is added on this basis.

[0029] More specifically:

[0030] like Figures 1 to 5 As shown:

[0031] In combination with the above content: the punching assembly 2 includes a sliding frame 21, a mounting frame 22 and a rotating rod 23. The outer side of the end of the connecting plate 1 is slidably connected to two sliding frames 21, the outer side of the end of the sliding frame 21 is fixedly connected to the mounting frame 22, one end of the mounting frame 22 is rotatably connected to the rotating rod 23, the middle inner side of the rotating rod 23 is rotatably connected to the rotating shaft 24, one side of the rotating shaft 24 is fixedly connected to a ring 25, the inner side of the end of the ring 25 is movably connected to a plurality of punching cones 26, and one end of the punching cone 26 is rotatably connected to the inner side of a threaded hole. Rod 27, the outer side of the threaded rod 27 is threadedly connected to the inner side of the ring 25, and the outer side of the middle part of the threaded rod 27 is fixedly connected to the rotating handle ring 28. The outer side of one end of the threaded rod 27 is fixedly connected to the limiting ball 29. The limiting ball 29 is a spherical structure. The inner side of the end of the rotating rod 23 is rotatably connected to the buffer rod 210. The outer side of one end of the buffer rod 210 is slidably connected to the inner side of the end of the mounting bracket 22. The outer side of the end of the buffer rod 210 is provided with a ring 211, and the outer side of one end of the ring 211 is fixedly connected to the lower surface of the end of the mounting bracket 22.

[0032] In this embodiment: when the user uses the device, the connecting plate 1 can be connected to the tractor. At this time, when the tractor pulls the device, it will drive the inner ring 25 and the punching cone 26 at the end of the mounting frame 22 to rotate, and then the ground film punching operation can be performed through the punching cone 26. When the user needs to adjust the distance of the punching cone 26 extending inside the ring 25, the user only needs to rotate the threaded rod 27 by rotating the handle 28. While the threaded rod 27 rotates, it will move inside the ring 25. While the threaded rod 27 moves, it can drive the punching cone 26 at the end of the threaded rod 27 to move inside the ring 25, and then the distance of the punching cone 26 inside the ring 25 can be adjusted. At the same time, the limiting ball 29 can limit the position of the threaded rod 27 to prevent the threaded rod 27 from driving the punching cone 26 to extend too much to the outside, and at the same time, the ring 25 and the punching cone 26 can drive the rotating rod 23 rotates, and at the same time drives the buffer rod 210 at the end of the rotating rod 23 to slide on the inner side of the end of the mounting frame 22, and the ring 211 can be compressed and store elastic potential energy, thereby increasing the flexibility of the punching cone 26. The punching cones 26 evenly distributed on the ring 25 can ensure that regular and uniform holes are formed on the ground film. The precise position control of the punching cones 26 helps to improve the accuracy of the punching, so that the depth of the hole can meet the needs of crop growth and promote root ventilation and water penetration. The distance that the punching cone 26 extends to the outside is adjustable, which means that the depth of the hole can be adjusted according to the root growth characteristics and soil conditions of different crops. For example, for crops with deeper roots, the depth of the hole can be deepened so that the roots can better stretch and absorb nutrients; and for crops with shallow roots, the depth of the hole can be appropriately reduced to avoid unnecessary effects on the root system.

[0033] Going further:

[0034] In an optional embodiment, a plurality of threaded holes 212 are provided on the inner side of the end of the connecting plate 1 , and a limiting bolt 213 is detachably connected to the inner side of a through hole provided on one side of the sliding frame 21 , and the limiting bolt 213 is threadedly connected to the threaded hole 212 .

[0035] In this embodiment: different crops and planting methods may require ground films of different widths. By adjusting the gap between the two sets of rings 25 through the sliding frame 21 and the limit bolt 213, it can adapt to ground films of different widths, so that the device can be widely used in various farmland environments. After determining the width of the ground film, adjusting the gap between the two rings 25 can ensure that the punching cones 26 are evenly distributed on the ground film, avoiding over-dense or over-sparse punching, thereby optimizing the air permeability and water and fertilizer retention effects of the ground film.

[0036] Going further:

[0037] In an optional embodiment, a through slot 214 is formed on the inner side of one end of the punching cone 26 .

[0038] In this embodiment, during the drilling process, soil particles may become stuck inside the drilling cone 26, increasing the resistance to drilling. The design of the through groove 214 allows the soil to flow out smoothly during the drilling process, reducing the friction between the drilling cone 26 and the soil, thereby improving the drilling efficiency. The through groove 214 can also effectively prevent the drilling cone 26 from getting stuck or twisted in the soil, thereby ensuring the continuity and stability of the drilling operation.

[0039] Working principle: When using the device, the user can connect the connecting plate 1 to the tractor. At this time, when the tractor pulls the device, it will drive the inner ring 25 and the punching cone 26 at the end of the mounting frame 22 to rotate, and then the ground film punching operation can be performed through the punching cone 26. When the user needs to adjust the distance of the punching cone 26 extending inside the ring 25, the user only needs to rotate the threaded rod 27 by rotating the ring 28. The threaded rod 27 rotates and moves inside the ring 25. When the threaded rod 27 moves, it can drive the punching cone 26 at the end of the threaded rod 27 to move inside the ring 25, and then the punching cone 26 can be adjusted in the ring. The distance inside the ring 25, and the limiting ball 29 can limit the position of the threaded rod 27 to prevent the threaded rod 27 from driving the punching cone 26 to extend too much to the outside. At the same time, the ring 25 and the punching cone 26 can drive the rotating rod 23 to rotate, and at the same time drive the buffer rod 210 at the end of the rotating rod 23 to slide on the inside of the end of the mounting bracket 22. At the same time, the ring 211 can be compressed and store elastic potential energy to increase the flexibility of the punching cone 26. The punching cones 26 evenly distributed on the ring 25 can ensure that regular and uniform holes are formed on the ground film. The precise position control of the punching cone 26 helps to improve the accuracy of the punching, making the holes The depth can meet the needs of crop growth and promote root ventilation and water penetration. The distance that the punching cone 26 extends to the outside is adjustable, which means that the depth of the hole can be adjusted according to the root growth characteristics and soil conditions of different crops. For example, for crops with deeper root systems, the hole depth can be deepened so that the roots can better stretch and absorb nutrients; while for crops with shallow root systems, the hole depth can be appropriately reduced to avoid unnecessary impact on the root system. Different crops and planting methods may require different widths of mulch. The gap between the two sets of rings 25 can be adjusted by the sliding frame 21 and the limit bolt 213 to adapt to mulch of different widths. The device can be widely used in various farmland environments. After determining the width of the ground film, adjusting the gap between the two rings 25 can ensure that the punching cones 26 are evenly distributed on the ground film, avoiding too dense or too sparse punching, thereby optimizing the air permeability and water and fertilizer retention effects of the ground film. During the punching process, soil particles may be blocked inside the punching cone 26, increasing the resistance to punching. The design of the through groove 214 allows the soil to flow out smoothly during the punching process, reducing the friction between the punching cone 26 and the soil, thereby improving the punching efficiency. The through groove 214 can also effectively prevent the punching cone 26 from getting stuck or twisted in the soil, ensuring the continuity and stability of the punching operation.
