Description

Technical Field

[0001] This application relates to the field of auxiliary equipment for crop planting, and in particular to a film-breaking device attached to a punching machine for agricultural planting. Background Technology

[0002] With the development of modern agricultural technology, mulching has become an indispensable technique in the production of tobacco, vegetables, and other cash crops. Mulching effectively increases soil temperature, retains moisture, and suppresses weed growth, thereby promoting early and rapid crop development and improving yield and quality. However, the perforation work before transplanting tobacco seedlings under mulching conditions faces unique technical challenges. Traditional electric perforators, including single-row and double-row models, are primarily designed for bare-field conditions. When applied to mulched fields, they generate a series of complex problems, affecting not only operational efficiency but also potentially leading to mulch damage and reduced planting quality.

[0003] Whether single-row or double-row, the core working component of an electric drilling machine is a high-speed rotating drill bit. The moment the drill bit contacts the soil, it first interacts with the plastic mulch film, which has a certain degree of toughness and elasticity. The rotation of the drill bit causes the mulch film to be cut and stretched, rather than directly cutting into the soil as it would in bare ground. More seriously, the high-speed rotation of the drill bit causes the mulch film in contact with it to rotate as well. Since the mulch film usually covers a large area and adheres tightly to the surface of the ridge, the rotating drill bit can easily roll up the surrounding mulch film, wrapping it around the drill bit's auger blades or shaft. This will have many negative impacts on agricultural production. For example, it will cause serious damage to the plastic film: when the drilling is completed, the drill bit will lift up the plastic film that is already wrapped around it, which will cause the plastic film to be torn, stretched or even lifted off completely, thus destroying the insulation effect of the plastic film; the drilling quality will decrease, and the plastic film wrapping will change the working state of the drill bit, which will reduce its cutting efficiency and may form irregular holes with insufficient depth. When tobacco seedlings are planted in such holes, the roots will not have sufficient contact with the soil, affecting their survival and subsequent growth; the operation efficiency will decrease, and the operator must frequently stop the machine to clean the broken film wrapped around the drill bit. This process is time-consuming and labor-intensive, and it will interrupt the continuous operation process.

[0004] Therefore, solving the problem of electric punching machines getting entangled in mulched fields has significant practical and economic value. With the promotion and expansion of mulch cultivation technology, the demand for specialized punching and film-breaking equipment suitable for mulch conditions is becoming increasingly urgent. Existing technologies include some film-breaking knives; for example, patent application CN115623947A discloses a film-breaking knife for crop cultivation. It includes a top plate and a film-breaking ring knife for puncturing the mulch film. A rotating plate is rotatably connected inside the top plate, and a first spring is fixedly connected to the bottom of the rotating plate. A connecting plate is fixedly connected to the other end of the first spring. The connecting plate and the film-breaking ring knife are connected via a telescopic assembly. A guide rod is fixedly connected to the bottom of the rotating plate, and one end of the guide rod passes through the connecting plate and is slidably connected to it. A sliding plate is slidably connected inside the film-breaking ring knife via a groove, and a hook is fixedly connected to the bottom of the sliding plate. The positioning assembly includes a support frame fixedly connected to the outer wall of the film-breaking ring knife. However, this film-breaking knife is a standalone, handheld or simple frame-supported dedicated film-breaking tool with a single function, focusing solely on film breaking and residual film collection. It is not integrated with existing punching machines, thus preventing continuous operation of breaking the film before punching. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an additional film-breaking device for an agricultural planting perforator, which is suitable for mulched fields. It enables the film to be broken before perforation, preventing film entanglement and avoiding serious damage to the film, while also improving the quality and efficiency of the perforation process.

[0006] To achieve the above and related objectives, this utility model provides an additional film-breaking device for an agricultural planting hole punch, including a fixed base for mounting the additional film-breaking device on the hole punch, a film-breaking arm mounted on the fixed base and with an adjustable position, and a film-breaking assembly installed at the end of the film-breaking arm away from the fixed base; the film-breaking assembly includes an annular film-breaking knife assembly and a drill rod installed in the annular cavity of the annular film-breaking knife assembly, with a plurality of film-attaching teeth provided on the side wall of the drill rod.

[0007] Furthermore, it also includes an adjusting and locking mechanism for adjusting and fixing the relative position of the rupture arm and the fixed seat, the adjusting and locking mechanism including an adjusting screw and two locking nuts.

[0008] Furthermore, it also includes a positioning component, which is mounted on the film-breaking arm via the positioning component, and the positioning component includes a cross-shaped positioning plate.

[0009] Furthermore, the drill rod is mounted on the node of the positioning plate, and the annular rupture knife assembly includes multiple knife rods respectively mounted on the connecting end of the positioning plate.

[0010] Furthermore, there are at least three tool holders.

[0011] Furthermore, the annular membrane-breaking knife assembly also includes a membrane-breaking knife, which is integrally formed and has a circular structure.

[0012] Furthermore, the annular membrane-breaking knife assembly also includes multiple membrane-breaking knives, which are arc-shaped and form an annular structure when they are enclosed.

[0013] Furthermore, the blade of the membrane-breaking knife has a serrated structure.

[0014] Furthermore, the end of the drill pipe furthest from the fixed seat has an inverted conical structure.

[0015] Furthermore, the punching machine is equipped with a punching drill bit, and the additional film breaking device is located on the same side of the punching machine as the punching drill bit, and is arranged at intervals along the direction of travel of the punching machine.

[0016] The beneficial technical effects of this utility model are as follows:

[0017] This utility model, by setting an additional film-breaking device, enables the film to be broken before drilling, based on the existing drilling machine. The additional film-breaking device is directly fixed on the drilling machine. The drilling machine drives the additional film-breaking device to move downward to cut the film, which facilitates subsequent drilling and avoids the situation of film entanglement and damage to the mulch film. It can be applied to mulched plots.

[0018] The additional film-breaking device of this utility model is fixedly connected to the punching machine through a fixed base. The film is broken and cut by the annular film-breaking knife assembly. A drill rod with film-hanging teeth is set in the annular cavity of the annular film-breaking knife assembly. The drill rod moves down and drills into the film at the punching position along with the film-breaking knife. After the film-breaking knife cuts and separates the film at the punching position, the film hangs on the film-hanging teeth and is lifted up with the drill rod, which avoids the cut film remaining at the punching position and causing the punching drill bit to be wrapped with film.

[0019] This utility model has the advantages of breaking the film before drilling, preventing the drill bit from getting tangled in the film, avoiding serious damage to the mulch film, and being simple and labor-saving to operate. Attached Figure Description

Detailed Implementation

[0027] Unless otherwise defined, all technical and / or scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. It should be understood that certain features of this invention (described in the context of separate embodiments for clarity) may also be provided in combination in a single embodiment. Conversely, multiple features of this invention (described in the context of a single embodiment for brevity) may also be provided separately or in any suitable combination or, where appropriate, in any other described embodiment of this invention. Certain features described in the context of various embodiments will not be considered essential features of those embodiments unless the embodiment is inoperable without those elements. The present invention is further illustrated below by specific examples; however, it should be noted that the specific process conditions and results described in the embodiments of this invention are for illustrative purposes only and should not be construed as limiting the scope of protection of this invention. All equivalent changes or modifications made in accordance with the spirit and essence of this invention should be covered within the scope of protection of this invention.

[0028] like Figures 1 to 4 As shown, this utility model provides an additional film-breaking device for an agricultural planting punching machine, including a fixed base 101 for mounting the additional film-breaking device 1 on the punching machine 10, and a film-breaking arm 102 mounted on the fixed base 101 and whose position is adjustable. A film-breaking component is installed at one end of the film-breaking arm 102 away from the fixed base 101. The film-breaking component includes an annular film-breaking knife assembly and a drill rod 107 installed in the annular cavity of the annular film-breaking knife assembly. A plurality of film-attaching teeth 108 are provided on the side wall of the drill rod 107.

[0029] Furthermore, the agricultural planting hole punch 10 of this application can be selected from existing equipment, such as a side-mounted stepping electric hole punch for transplanting, or a double-row stepping hand-held electric hole punch for seedling transplanting. The hole punch 10 is equipped with a hole punch 2, and the auxiliary film-breaking device 1 and the hole punch 2 are located on the same side of the hole punch 10 and are spaced apart along the direction of travel of the hole punch 10. The auxiliary film-breaking device 1 and the hole punch 2 follow the hole punch 10 and move up and down under the drive of the up-and-down drive structure of the hole punch 10, thereby performing the operation of breaking the film before punching.

[0030] Furthermore, the mounting base 101 of this application is used for fixed connection with the upper and lower drive structure of the drilling machine 10, and the fixed connection method includes, but is not limited to, bolt connection, riveting, etc. Figures 1 to 3 As shown, the device of this application also includes an adjustment and locking mechanism for adjusting and fixing the relative position of the film-breaking arm 102 and the fixed seat 101. The adjustment and locking mechanism includes an adjusting screw 109 and two locking nuts 110. Furthermore, one end of the adjusting screw 109 is fixedly connected to the fixed seat 101 by bolts, riveting, welding, or other means, and the other end is movably connected to the film-breaking arm 102. The two locking nuts 110 are sleeved on the adjusting screw 109 and located on the upper and lower sides of the film-breaking arm 102, respectively, to lock the position of the film-breaking arm 102. When it is necessary to adjust the position of the film-breaking arm 102, the two locking nuts 110 are loosened, the film-breaking arm 102 is moved along the adjusting screw 109 to a suitable height position, and then the two locking nuts 110 are tightened to lock the film-breaking arm 102 in the current position.

[0031] Furthermore, such as Figure 1 , Figure 2 As shown, the device of this application also includes a positioning component. The film-breaking component is mounted on the film-breaking arm 102 via the positioning component. The positioning component includes a cross-shaped positioning plate 104 and two connecting rods 103. One end of the connecting rod 103 is fixedly connected to the film-breaking arm 102, and the other end is fixedly connected to the positioning plate 104. The fixed connection method includes, but is not limited to, bolt connection, welding, snap-fit, and riveting.

[0032] Furthermore, the drill rod 107 of this application is installed on the node of the positioning plate 104, and the annular film-breaking knife assembly includes a plurality of downwardly extending knife rods 105 respectively installed on the connecting ends of the positioning plate 104. There are at least three knife rods 105, preferably four, and they are evenly installed on the four connecting ends of the positioning plate 104, thereby ensuring uniform force during film breaking, which helps the annular film-breaking knife assembly to stably cut into the mulch film, reduce shaking, and avoid uneven tearing of the mulch film or inconsistent tear sizes, thereby ensuring consistent film breaking quality around each hole; and during the film breaking process, the multiple knife rods 105 can share the resistance generated when cutting into the mulch film and soil. Compared with a single knife rod 105 or fewer knife rods 105, this application can reduce the stress borne by each knife rod 105 and reduce the risk of deformation or damage to the knife rod 105.

[0033] Furthermore, the annular film-breaking knife assembly of this application also includes a film-breaking knife 106 installed at the bottom of the knife rod 105. The film-breaking knife 106 is integrally formed and has a circular structure. Alternatively, the annular film-breaking knife assembly also includes multiple film-breaking knives 106, which have an arc-shaped structure and are arranged to form a circular structure. This circular structure gives the film-breaking knife 106 higher strength, better film-breaking effect, and lower cost. In addition, when the film-breaking knife 106 is integrally formed, its structure is reinforced and stable, with good uniform stress distribution, making it suitable for farmland requiring high strength, high reliability, and long-term stable operation, such as continuous operation in large-scale standardized farmland. When there are multiple film-breaking knives 106, the arc-shaped film-breaking knife 106 can be replaced independently, facilitating maintenance and making it suitable for farmland with variable operating conditions that may require flexible adjustments.

[0034] Furthermore, for ease of manufacturing, the film-breaking knife 106 of this application can adopt a flexible blade-like structure, and the blade of the film-breaking knife 106 has a serrated structure, which can cut the film more efficiently and adapt to complex field operation environments.

[0035] Furthermore, the end of the drill rod 107 furthest from the fixing base 101 has an inverted conical structure. To ensure that the film cut after rupture can be hung on the drill rod 107 and lifted by the film-hanging teeth 108 to separate from the film covering on the plot, the bottom end of the drill rod 107 extends downward to below the bottom end of the rupture blade 106. In addition, the inverted conical structure of the drill rod 107 reduces the amount of soil carried by the drill rod 107, lowers operational resistance, and prevents soil from affecting the rupture effect or causing entanglement.

[0036] Furthermore, this application provides, by way of example, various embodiments of assembling the additional membrane breaking device 1 with the punching machine 10, as follows:

[0037] Example 1

[0038] In this embodiment, the drilling machine 10 is a side-mounted step-transplanting electric hole-drilling machine from the prior art. It is a side-mounted single-row double-hole drilling machine. Its specific structure includes a frame and a handrail on the frame, a front roller, a rear wheel, a battery, an electrical control box, a walking motor that provides walking power to the rear wheel, a three-speed changeover switch, an air switch, etc., as well as an upper and lower motor located in the middle of the upper end of the frame, and a sliding arm and a T-shaped connecting arm connected to the upper and lower motors through a transmission structure for setting the drilling drill bit 2. The upper and lower motors and their transmission structure, as well as the sliding arm, T-shaped connecting arm, etc., can be the upper and lower drive structure of the drilling machine 10 in this utility model.

[0039] In practical implementation, the additional film-breaking device 1 and the drilling bit 2 of this application can be installed along the traveling direction of the drilling machine 10, as follows: Figure 4 As shown in Figure 4, the arrow above the puncher 10 indicates the forward direction of the puncher 10. Figure 4 The arrow on the front side of the punching machine 10 indicates the direction of vertical movement of the additional membrane breaking device 1 and the punching drill bit 2.

[0040] like Figure 4 As shown, the additional film-breaking device 1 is fixedly installed on the punching machine 10 via the fixing base 101. At this time, the additional film-breaking device 1 is located in front of the punching drill bit 2 and is on the same working line as the punching drill bit 2. After the installation of the additional film-breaking device 1 is completed, it can be put into use. The punching machine 10 drives the additional film-breaking device 1 and the punching drill bit 2 to the required working position. The up and down drive structure of the punching machine 10 drives the additional film-breaking device 1 and the punching drill bit 2 to move down. The film-breaking blade 106 at the bottom of the additional film-breaking device 1 cuts the film. The drill rod 107 inside the film-breaking blade 106 drills down, removing the film. The cut film is brought to the film-attaching teeth 108. After the film is broken, the upper and lower drive structure drives the additional film-breaking device 1 to move upward, and the film-breaking knife 106 separates from the film. At the same time, the cut film is carried away with the film-attaching teeth 108 on the drill rod 107, realizing the complete cutting of the film. Meanwhile, the drilling bit 2 behind performs drilling operations. After one film-breaking and drilling operation is completed, the drilling machine 10 continues to move forward. The additional film-breaking device 1 performs film-breaking operation on the previous drilling position, and the drilling bit 2 drills holes on the next drilling position after the film is broken. This process is repeated until all drilling operations are completed.

[0041] It should be noted that in this embodiment, the drilling machine 10 has one up-and-down drive structure, which drives the additional film-breaking device 1 and the drilling bit 2 to move up and down simultaneously. However, it is not limited to this. This embodiment is only a preferred embodiment. In other embodiments, the up-and-down drive structures used to drive the additional film-breaking device 1 and the drilling bit 2 to move up and down can be set separately into two, which can drive the additional film-breaking device 1 and the drilling bit 2 up and down independently. The setting of the up-and-down drive structure does not affect the implementation of the technical solution of breaking the film before drilling in this application. It is only necessary to realize the up-and-down drive function. Therefore, the up-and-down drive structure is not specifically limited here.

[0042] Example 2

[0043] In this embodiment, the punching machine 10 is a double-row stepping hand-held electric punching machine for seedling transplanting, which includes a frame and a handrail, front wheel and rear wheel mounted on the frame. It also includes a battery, a PLC unit, a motor controller and a walking motor that provides driving power to the rear wheel. The front of the frame is provided with an upward mounting frame. The mounting frame is provided with a lifting beam that can move up and down along the mounting frame. Two symmetrical punching devices are provided on both sides of the lifting beam. The punching device includes a rotary motor and a punching drill bit 2 connected to the output end of the rotary motor. An air switch is provided on the handrail. The battery, air switch, PLC unit, motor controller and walking motor are electrically connected in sequence. The rotary motor is electrically connected to the air switch. An encoder is provided on the outer end of the output shaft of the walking motor. The encoder is electrically connected to the PLC unit. When the double-row single-hole punching machine 10 is applied to the pre-film breaking and post-punching technology of this application, the fixed square tube structure at its lifting beam can be replaced with a structure suitable for installing the pre-film breaking and post-punching technology of this application, such as the T-shaped connecting arm in the aforementioned side-mounted step-transplanting electric punching machine. This is common knowledge to those skilled in the art, and therefore will not be elaborated here. Furthermore, the principle of this embodiment is the same as that of Embodiment 1 above, and will not be elaborated here.

[0044] In addition, it should be noted that, apart from the aforementioned side-mounted stepping electric hole puncher for transplanting and the double-row stepping hand-held electric hole puncher for seedling transplanting, other existing hole punchers that can serve as carriers for the pre-film breaking and hole punching technology in this application are also acceptable. It is not limited to the two existing hole punching technology solutions mentioned above, and will not be elaborated further here.

[0045] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
