Description

Technical Field

[0001] This utility model belongs to the field of seedling cultivation technology, specifically relating to a punching device for planting seedlings. Background Technology

[0002] Mulching refers to the measure of covering the ground surface with agricultural plastic film; it can effectively reduce soil moisture evaporation, conserve moisture during drought and improve moisture after rain, promote crop water absorption and growth, and improve soil moisture utilization efficiency.

[0003] The core advantage of transplanting after the mulch film is laid is that it optimizes the soil environment in advance, providing more stable growth conditions for seedlings. Pre-mulching quickly raises soil temperature, especially in early spring or cold seasons, allowing the seedling roots to adapt rapidly to the soil temperature and shortening the recovery period. For example, after transplanting greenhouse vegetables, the stable temperature under the film avoids direct stimulation of the roots by low temperatures, promoting new root germination. Furthermore, spraying herbicides or using physical barriers before mulching can significantly reduce weed germination rates. Completing this step before transplanting is crucial. This method avoids interference with seedling roots during later weeding operations, ensuring seedlings grow in an environment free from weed competition; sufficient watering before mulching effectively maintains stable soil moisture under the film; frequent watering is unnecessary after transplanting, reducing mechanical damage to seedlings during field operations and preventing root diseases caused by excessive moisture under the film; mulching before transplanting avoids tools tearing the film during transplanting, ensuring the film's integrity; for example, when planting vegetables, directly punching holes in the film to plant seedlings protects the film's function while enabling seedling transplantation.

[0004] Current methods of mulching, whether manual or mechanical, suffer from the problem of balancing efficiency and precision. Mechanical mulching easily tears or misaligns the mulch film, while manual mulching is time-consuming and costly, leaving circular gaps in the film. Since the root system of seedlings occupies a much larger area than the stem, holes need to be dug in the soil and backfilled after transplanting. Therefore, the hole size must accommodate the seedling roots and the digging tools, resulting in a hole diameter much larger than the seedling stem. After transplanting, although the soil covers the seedling roots, the soil around the stem is exposed in the holes, no longer covered by the mulch film. This leads to rapid changes in humidity and temperature, and increased evaporation of soil moisture. Summary of the Invention

[0005] Based on this, this application provides a punching device for planting seedlings to solve the technical problem in the prior art where the size of the holes is too large after punching, resulting in the soil around the stem of the seedling being exposed, causing rapid changes in humidity and temperature and easy evaporation of soil moisture.

[0006] The technical solution to the above-mentioned technical problems in this application is as follows:

[0007] A punching device for planting seedlings, comprising:

[0008] The membrane breaking assembly includes two conical tips and slides formed on the outer side of the conical tips, with a hanging rod slidably connected in each slide.

[0009] The base component has two cone tips that are respectively hinged to the base component and are symmetrical to each other. When the two cone tips are engaged, they are located below the base component and form a cone. When the two cone tips are opened, they can tear a gap in the mulch film.

[0010] Arrangement components are used to adjust the number and spacing of the basic components;

[0011] The suspension assembly includes a lifting section, the arrangement component is connected to the lower end of the suspension assembly, and multiple suspension rods are connected to the lifting section. The lifting section can drive the multiple suspension rods to vertically rise and fall to realize the opening and closing of the two cone tips.

[0012] Preferably, the basic component includes a circular tube and two sliders formed on both sides of the circular tube; the outer sides of the upper ends of the two cone tips are respectively rotated on both sides of the lower end of the circular tube by torsion springs, and the two sliders are connected to the arrangement component.

[0013] Preferably, the arrangement component includes a transverse groove with one end open and an end cap fastened to the open end of the transverse groove. Two sliders on the same round tube slide in contact with the two side walls of the transverse groove respectively. The transverse groove is connected to the lower end of the suspension component.

[0014] Preferably, the vertical plane where the two lifting rods are located is parallel to the side wall of the transverse groove and perpendicular to the vertical plane where the two sliders are located.

[0015] Preferably, an elongated hole is provided on one side wall of the transverse groove, and a threaded hole is provided on the side of the slider that slides in the transverse groove, and a locking bolt is connected in the threaded hole.

[0016] Preferably, the suspension assembly further includes a hanger and a vertical tube fixed to the hanger, the vertical tube being provided with a handle, the hanger being fixed to a horizontal groove, and the lifting part sliding in the vertical tube.

[0017] Preferably, the lifting part includes a horizontally arranged mounting groove that is parallel to the side wall of the horizontal groove. A vertical rod is fixed on the mounting groove and slides vertically in the vertical tube. The upper end of the vertical rod extends out of the vertical tube and is formed with a handle. The handle is located below the handle. The upper end of the lifting rod can slide and lock in the mounting groove.

[0018] Preferably, the arrangement assembly further includes a graduated ruler that is slidably connected to one side wall of the transverse groove in a horizontal state.

[0021] Compared with the prior art, this application has at least the following advantages:

[0022] This application provides a perforating device for seedling planting. A suspension assembly lowers a distribution assembly, and multiple film-breaking components at the lower ends of multiple base components contact the mulch film. This means that a cone formed by two interlocking cone tips moves downwards and pierces the mulch film. Maintaining the suspension assembly's height, the lifting part is pulled upwards, causing the lifting rod to rise. As the rod rises, it slides in a track away from the cone tips, causing the track to rotate and open the cone tips within the hinged position. After the lower ends of the two cone tips pierce the mulch film, they spread out to both sides, tearing the mulch film around the point where the cones pierce it, creating a slit. This slit covers the edge of the seedling stem, reducing exposed soil and maintaining stable humidity and temperature around the seedling roots, preventing excessive evaporation of soil moisture.

[0037] Please refer to Figures 1 to 10 In one specific embodiment of this application,

[0038] A punching device for planting seedlings, comprising:

[0039] The membrane breaking assembly includes two cone tips 104 and slides 105 formed on the outside of the cone tips 104, with a hanging rod 106 slidably connected in each slide 105;

[0040] The base component has two cone tips 104 that are respectively hinged to the base component and are symmetrical to each other. When the two cone tips 104 are fastened together, they are located below the base component and form a cone. When the two cone tips 104 are opened, they can tear a gap in the mulch film.

[0041] Arrangement components are used to adjust the number and spacing of the basic components;

[0042] The suspension assembly includes a lifting section, the arrangement assembly is connected to the lower end of the suspension assembly, and multiple hanging rods 106 are connected to the lifting section. The lifting section can drive the multiple hanging rods 106 to rise and fall vertically to realize the opening and closing of the two cone tips 104.

[0043] The suspension component can be a suspension bracket or a suspension beam, and it can be a device that can be manually operated; the arrangement component can be a slide rail or a guide rail, and the base component is a platform or device that can slide on the slide rail or guide rail; the lifting part can be a clamp (to clamp the upper end of the boom 106 to complete the connection) or a frame that can be connected to the upper end of the boom 106 and drive the boom 106 to rise and fall.

[0044] During operation, the two conical tips 104 in the film-breaking assembly are hinged to the lower end of the base assembly, and the upper end of the hanger 106 is connected to the lifting part. Then, by connecting multiple base assemblies to the arrangement assembly, the base assemblies are evenly distributed within the arrangement assembly. The suspension assembly can then be moved above the mulch film, and then moved downwards, causing the arrangement assembly to descend. Multiple film-breaking components at the lower ends of the base assemblies contact the mulch film, meaning the cone formed by the two interlocking conical tips 104 moves downwards and pierces the mulch film (at the interlocking ends of the two conical tips 104). Then, keeping the suspension assembly at a constant height, the lifting part is pulled upwards. In the initial state (i.e., when the two conical tips 104 are interlocked, the lower end of the hanger 106 is located at the innermost side of the slide rail 105), the lifting part raises the hanger 106. As the hanger 106 rises, it slides in the slide rail 105 away from the conical tips 104, thus... The slide rail 105 drives the cone tip 104 to rotate and open under the constraint of the hinge position (the two locked cone tips 104 rotate away from each other to open, the boom 106 rises and falls vertically, it does not move horizontally or rotate, when the boom 106 rises, it slides in the slide rail 105, when the boom 106 rises, it drives the slide rail 105 to rotate around the hinge position of the cone tip 104, the contact position between the boom 106 and the slide rail 105 moves from one side of the slide rail 105 to the other side, that is, the boom When the rod 106 rises, it slides in the slide rail 105. In fact, when the rod 106 rises, it drives the slide rail 105 to tilt and change the contact position between the slide rail 105 and the rod 106, so that the slide rail 105 gradually tilts, thereby driving the hinge position of the cone tip 104 to rotate. This causes the lower ends of the two cone tips 104 to penetrate the mulch film and then spread out to both sides. With the position where the cone penetrates the mulch film as the center, it spreads out to both sides, thereby tearing the mulch film and forming a gap on the mulch film.

[0045] By using the above method, a slit can be made in the mulch film. When transplanting seedlings, workers can open the slit, dig a hole for the exposed soil, place the seedling roots into the hole, backfill the soil, and then loosen the mulch film. The mulch film will then return to the slit state, covering the edge of the seedling stem. This reduces the amount of exposed soil, keeps the humidity and temperature of the soil around the seedling roots stable, and prevents the soil from being exposed and causing the water in the soil to evaporate too quickly.

[0046] Specifically, an embodiment is provided for the basic components in the above process:

[0047] The basic component includes a circular tube 101 and two sliders 102 formed on both sides of the circular tube 101; the outer sides of the upper ends of the two cone tips 104 are respectively rotated on both sides of the lower end of the circular tube 101 by torsion springs, and the two sliders 102 are connected to the arrangement component.

[0048] Two sliders 102 can connect the round tube 101 to the arrangement assembly. In this way, multiple round tubes 101 from multiple basic components can be evenly connected to the arrangement assembly. At the same time, as the lifting part drives the lifting rod 106 to rise, the slide rail 105 drives the cone tip 104 to rotate and open at the lower end of the round tube 101 to complete the tearing of the mulch film. During this process, the torsion spring undergoes elastic deformation. When the lifting rod 106 is no longer under the upward driving force after use, the torsion spring can drive the cone tip 104 to rotate and close at the lower end of the round tube 101.

[0049] In the above method, multiple basic components can be arranged, and multiple film-breaking components are connected to the arrangement components. Under the drive of the suspension components, multiple film-breaking components can simultaneously tear multiple gaps in the mulch film. Furthermore, the spacing between the multiple basic components can be adjusted on the arrangement components to adjust the spacing between the multiple gaps, thereby meeting the plant spacing required when transplanting different types of seedlings.

[0050] Specifically, an embodiment of the arrangement components in the above process is provided:

[0051] The arrangement assembly includes a horizontal groove 201 with one end open, and an end cap 204 fastened to the open end of the horizontal groove 201. Two sliders 102 on the same round tube 101 slide in contact with the two side walls of the horizontal groove 201 respectively. The horizontal groove 201 is connected to the lower end of the suspension assembly.

[0052] During operation, first open the end cap 204 to open one end of the transverse groove 201. Then, the two sliders 102 on the same round tube 101 can be aligned with the two side walls of the transverse groove 201 and slid in. According to the needs of the site, after sliding several round tubes 101 into the transverse groove 201, the open end of the transverse groove 201 can be sealed again with the end cap 204 to prevent the sliders 102 from sliding out, thus completing the installation of multiple basic components.

[0053] The above method allows for adjusting the number of basic components according to demand to meet the number of gaps that can be generated in a single operation. In other words, by driving the suspension components down, a corresponding number of film-breaking components are driven to tear the film, thus meeting the demand. Different numbers of gaps can be torn open in a single operation of the suspension components.

[0054] In addition, in the above process, in order to avoid interference between the lifting rod 106 and the horizontal groove 201 when the lifting rod 106 is raised and lowered, the vertical plane where the two lifting rods 106 are located is parallel to the side wall of the horizontal groove 201 and perpendicular to the vertical plane where the two sliders 102 are located.

[0055] In other words, the vertical planes where the two sliders 102 are located are perpendicular to the side walls of the transverse groove 201. During installation, the two sliders 102 slide into the two side walls of the transverse groove 201 respectively. At this time, the vertical planes where the two lifting rods 106 are located are parallel to the side walls of the transverse groove 201. Therefore, when the two lifting rods 106 are raised and lowered, there will be no obstacles in the direction of the lifting rods 106. Moreover, it can keep several lifting rods 106 in several membrane breaking components on the same vertical plane. In this way, it is convenient to use a lifting part to drive all the lifting rods 106 at the same time and control the cone tips 104 in several membrane breaking components to open at the same time.

[0056] In the above process, after connecting several basic components in the transverse groove 201, their positions need to be fixed to fix the spacing between the multiple basic components and prevent it from changing, so as to keep the spacing between the cones in the several membrane breaking components stable.

[0057] Therefore, in this application, an elongated hole 202 is provided on one side wall of the transverse groove 201, and a threaded hole is provided on the side of the slider 102 that slides in the transverse groove 201, and a locking bolt 103 is connected in the threaded hole.

[0058] As the slider 102 with the threaded hole slides into the corresponding side wall of the transverse groove 201, the locking bolt 103 will enter the elongated hole 202. After the round tube 101 reaches the appropriate position, the locking bolt 103 can be tightened, which will increase the pressure on the transverse groove 201 while the locking bolt 103 penetrates into the threaded hole. Thus, the locking bolt 103 and the slider 102 are clamped on the side wall of the transverse groove 201, and the position of the round tube 101 is fixed.

[0059] In the above manner, when multiple basic components are installed, the locking bolts 103 can be used to fix the position of multiple round tubes 101. After the multiple round tubes 101 are evenly distributed in the transverse groove 201, their positions are fixed, preventing them from moving again and changing the spacing. This can achieve the even distribution of multiple round tubes 101, and also improve the adjustment of the spacing and maintain stability.

[0060] Specifically, an embodiment of the suspension assembly in the above process is provided:

[0061] The suspension assembly also includes a hanger 301 and a vertical tube 302 fixed on the hanger 301. A handle 303 is provided on the vertical tube 302. The hanger 301 is fixed on the horizontal groove 201. The lifting part slides in the vertical tube 302.

[0062] During operation, by holding the handle 303, the hanger 301 can be raised and lowered through the vertical pipe 302, thereby enabling the hanger 301 to raise and lower the horizontal groove 201 fixed at the lower end of the hanger 301, which can raise and lower several basic components and several film breaking components in the horizontal groove 201. When descending, the film breaking components tear gaps in the ground film.

[0063] The above method allows for the creation of multiple gaps in a single operation during manual processing, while also facilitating handheld handling and movement.

[0064] Because the position of the circular tube 101 changes when adjusting the spacing in the transverse groove 201 during the above process, in order to keep the lifting rod 106 in a vertical position, a specific embodiment of the lifting part in the above process is provided:

[0065] The lifting part includes a horizontally arranged mounting groove 304, which is parallel to the side wall of the horizontal groove 201. A vertical rod 305 is fixed on the mounting groove 304. The vertical rod 305 slides vertically in the vertical tube 302. The upper end of the vertical rod 305 extends out of the vertical tube 302 and is formed with a handle 306. The handle 306 is located below the handle 303. The upper end of the lifting rod 106 can slide and lock in the mounting groove 304.

[0066] When in use, hold the handles 303 with both hands and lower the vertical tube 302, which in turn lowers the hanger 301 and the horizontal groove 201. The horizontal groove 201 then lowers the round tube 101, causing the two cone tips 104 at the lower end of the round tube 101 to pierce the mulch film. Then, hook the handle 306 upward with your fingers and use the handle 306 to slide the vertical rod 305 upward in the vertical tube 302, causing the height of the installation groove 304 to rise relative to the horizontal groove 201. This causes the installation groove 304 to move upward away from the horizontal groove 201. The installation groove 304 then pulls the hanger 106 vertically upward. The two hangers 106 can then rotate and open the two cone tips 104 that have pierced the mulch film, thus tearing a gap in the mulch film at the point where they are pierced.

[0067] The above process allows for manual operation by simply moving the handle 303 to the designated position, pressing down to allow the cone tip 104 to pierce the mulch film, and then pulling up the handle 306 to open the cone tip 104 and tear a gap. This is not only convenient, but also allows for quick operation of multiple points and multiple gaps when multiple mulch film breaking components are installed.

[0068] Additionally, according to Figure 4 and Figure 9The contents show the structure of the upper end of the boom 106 and the mounting groove 304. Several grooves are opened on the lower inner surface of the mounting groove 304 (that is, after the boom 106 is inserted into the groove, the boom 106 remains vertical, and the lower round tube 101 is fixed in the corresponding position in the horizontal groove 201 to keep the boom 106 vertical). After the boom 106 slides into the mounting groove 304 from one end, it will be inserted into the corresponding groove after reaching the corresponding position. At this time, the boom 106 will neither slide in the mounting groove 304 nor move up and down in the mounting groove 304 (because of the torsion spring, the cone tip 104 always maintains a downward pulling force on the boom 106). When the mounting groove 304 moves up and down, the boom 106 will not slide in the horizontal direction, which can ensure that the boom 106 is stable in the installation position and moves up and down with the mounting groove 304.

[0069] In this application, the structure of the upper end of the hanger 106 and the mounting groove 304 is square (e.g., Figure 4 Correspondingly, the groove should also be square, at which point the boom 106 will rise and fall vertically.

[0070] The punching device used for seedling planting produces multiple slits with identical spacing after a single operation, meeting the needs of seedling planting. These slits created in a single operation can be considered a group. In subsequent operations, while the spacing between slits in another group is also identical and consistent with the previous group, the position of the slits within each group—that is, the distance between the last slit of the previous group and the first slit of the next group—must also maintain consistency with the spacing within each group.

[0071] Therefore, the arrangement assembly also includes a graduated ruler 203, which is slidably connected to one side wall of the transverse groove 201 in a horizontal state.

[0072] When using the device, measure the distance from the center of the last film-breaking component to the nearest end of the transverse groove 201. Then, based on the distance between the two film-breaking components, move the measuring ruler 203 so that the distance between the end of the measuring ruler 203 near the outside of the transverse groove 201 and the last film-breaking component is equal to the distance between the two film-breaking components. This way, after processing one set of gaps using the seedling punching device, when processing the next set of gaps, the end of the measuring ruler 203 near the outside of the transverse groove 201 is positioned at the center of the last gap in the previous set of gaps. Then, use the seedling punching device to process the next set of gaps. At this time, the distance between the gap closest to the previous set of gaps in the next set of gaps and the last gap in the previous set of gaps is equal to the distance between each set of gaps.

[0073] Furthermore, while manually moving the seedling-planting hole-drilling device is acceptable for short periods, prolonged use will lead to a decline in physical strength.

[0074] Therefore, this application also includes a moving component, which includes a trolley 401, and the suspension component is connected to the trolley 401 and can be raised and lowered in the vertical direction. The trolley 401 can drive the suspension component to move.

[0075] Car 401 can be either an autonomous vehicle or a manually driven vehicle.

[0076] During use, the suspension assembly can be automatically moved by the trolley 401 along the length of the ground. When it reaches the corresponding position, the suspension assembly can be manually pressed down to break the film, and then the trolley 401 can move again to perform the next set of gap processing.

[0077] The aforementioned vehicle enables the suspension components to move without manual intervention, significantly reducing physical exertion. Once the vehicle is in position, the suspension components can be manually depressed, reducing workload and labor intensity.

[0078] Specifically, an embodiment is provided for the connection between the vehicle 401 and the suspension assembly in the above process:

[0079] The trolley 401 has a sliding hole 402 formed therein, the vertical tube 302 slides in the sliding hole 402, and a spring 403 is provided between the upper end face of the trolley 401 and the upper end outer wall of the vertical tube 302.

[0080] When the handle 303 is manually pressed down, the handle 303 drives the vertical tube 302 to slide down in the sliding hole 402. At this time, the vertical tube 302 compresses the spring 403. After the vertical tube 302 descends and the membrane breaking component breaks the membrane, the handle 303 is released. Under the action of the spring 403, the vertical tube 302 will rise back to the initial position (the position without pressing down), realizing automatic reset.

[0081] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
