Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment technology, specifically to an electric heating perforation device for agricultural mulch film with adjustable hole spacing. Background Technology

[0002] Currently, in modern agricultural production, mulch film technology is widely used in the planting of various crops due to its advantages such as effectively increasing soil temperature, maintaining soil moisture, and suppressing weed growth. This technology has significantly promoted increased crop yields and plays an important role in the agricultural field. However, in the actual use of mulch film, there are still some technical problems that urgently need to be solved. For example, after the mulch film is laid, it is usually necessary to make holes in it to ensure that crops can emerge smoothly. Currently, this process mainly relies on manual labor, which is not only inefficient, but also leads to continuously rising labor costs as the scale of planting expands, making it difficult to meet the needs of efficient production in modern agriculture. Although mechanical hole-making technology has emerged in recent years, existing technologies are mostly used to make holes in already laid mulch film, which can easily lead to problems such as tearing and misalignment of the mulch film, thus affecting its effectiveness. In addition, existing mechanical hole-making technologies generally have the problem of inconvenient adjustment of row spacing and plant spacing, and cannot flexibly adapt to the planting needs of different crops. Inappropriate row and plant spacing can negatively impact crop growth. For example, insufficient spacing can hinder seedling development, while excessively large hole diameters reduce the utilization rate of the mulch film and land. Therefore, developing an agricultural mulch film perforation device that integrates perforation and mulching while offering flexible hole spacing adjustment is a pressing technical challenge in current agricultural production. This invention aims to provide an electric heating perforation device for agricultural mulch film with adjustable hole spacing through innovative design, thereby addressing the aforementioned problems and meeting diverse planting needs. Utility Model Content

[0003] This invention addresses the shortcomings of existing agricultural mulch film perforation devices, such as the inability to flexibly adjust row and plant spacing, significant problems with film tearing and misalignment, and poor applicability. It provides an electric heating perforation device for agricultural mulch film with adjustable hole spacing. The device achieves precise adjustment of row and plant spacing before perforation through mechanical structure design, and, combined with an electric heating perforation module, completes continuous perforation operations on the agricultural mulch film.

[0004] This utility model provides an electric heating perforation device for agricultural mulch film with adjustable hole spacing, including a frame, a film pressing module, an electric heating perforation module, and a film roll. The frame consists of a cross frame and side frames for mounting and supporting all components. One end of the frame is movably connected to the film roll via a bearing seat, and the other end is movably connected to the electric heating perforation module via a bearing seat.

Furthermore, the sliding bracket is fixedly connected to the rotating shaft by screws. When the screws are loosened, the sliding bracket can slide axially on the rotating shaft.

[0006] The technical solution of this utility model also includes specific adjustment methods for row spacing and plant spacing.

[0007] Furthermore, the process of laying and punching the mulch film of this utility model is as follows: S1: Unroll the film roll and lay it on the electric heating punching device. After the mulch film contacts the arc-shaped support plate, it continues to unfold, passing between the first and second pressing rods, and the end is fixed to the ground; S2: Start the electric heating punching module and start the drive motor at the same time.

[0013] This utility model provides an electric heating perforation device for agricultural mulch film with adjustable hole spacing. Through its mechanical structure design, it achieves precise adjustment of row spacing and plant spacing before perforation, and, combined with an electric heating perforation module, completes continuous perforation operations on the agricultural mulch film. The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0014] As shown in Figure 1, the overall structure of this utility model includes a frame, a film pressing module, an electric heating perforation module, and a film roll. The frame consists of a cross frame 1 and side frames 2, used to install and support all components. Tires 4 are installed at the bottom of the frame to support the device and fix it to the agricultural vehicle. One end of the frame is movably connected to the film roll 10 via a bearing seat 3, and the other end is movably connected to the electric heating perforation module 13 via a bearing seat 3. The film pressing module is located at one end of the frame and includes a first film pressing rod 8, a second film pressing rod 9, and a film pressing rod support 7. The first film pressing rod 8 and the second film pressing rod 9 are respectively fixed to the film pressing rod support 7 with bolts, used to control the flow direction of the agricultural film after perforation and to maintain its unfolded state.

[0015] The electric heating perforation module also includes a slide groove 14, which guides the sliding support 135 to move axially along the rotation axis 5. The distance between the first pressure rod 8 and the second pressure rod 9 is a fixed value, which is used to control the unfolding state of the mulch film.

[0016] The electrothermal drilling module 13 is the core component of this utility model, as shown in Figures 4 to 5. Figure 6As shown, its core component is a rotating shaft 5, with a driven wheel and a support wheel 15 fixedly connected to its two ends respectively. The driven wheel is connected to the driving wheel via a synchronous belt 12, and the driving wheel is driven by a drive motor 11. A slot is formed on the side of the support wheel 15, and an adjusting shaft is slidably connected within the slot. The adjusting shaft is used to adjust the plant spacing. The electrothermal drilling module also includes an adjusting block 133, an electrothermal block 131, an arc-shaped support plate 132, a sliding bracket 135, and an adjusting drum 137. The top of the adjusting block 133 is fixedly connected to the electrothermal block 131, and the arc-shaped support plate 132 is fixedly connected to the outer circumference of the electrothermal block 131. The arc-shaped support plate 132 is used to support the unfolded mulch film and guide it to contact the electrothermal block 131 for drilling. The adjusting block 133 is slidably connected to the support wheel 15 via the adjusting shaft. The distance between the electrothermal block 131 and the rotating shaft 5 is adjusted by sliding the adjusting shaft, thereby adjusting the plant spacing.

[0017] The sliding bracket 135 has a forward-rotating thread 134 at one end and a reverse-rotating thread 136 at the other end, which are movably connected to the forward-rotating and reverse-rotating threads at both ends of the adjusting cylinder 137, respectively. By rotating the adjusting cylinder 137, the sliding bracket 135 moves axially along the rotating shaft 5, thereby adjusting the distance between adjacent sliding brackets and achieving the purpose of adjusting the opening spacing. The sliding bracket 135 is fixedly connected to the rotating shaft 5 by screws 138. When the screws 138 are loosened, the sliding bracket 135 can slide axially on the rotating shaft 5.

[0018] In practical applications, the operator first installs the film roll 10 on the bearing seat 3 and rotates the adjusting wheel to a 90-degree clockwise position, bringing the adjusting shaft to its limit position. Next, the operator loosens the fixing screw 138 between the sliding bracket 135 and the rotating shaft 5, allowing the sliding bracket 135 to slide axially on the rotating shaft 5. At this point, the operator rotates the adjusting drum 137, adjusting the forward-rotating thread 134 and the reverse-rotating thread 136 at both ends of the drum 137 to move the sliding bracket 135 along the rotating shaft 5. After adjusting to the row spacing suitable for the current crop planting needs, the operator stops rotating the adjusting drum 137 and tightens the fixing screw 138. Subsequently, the operator continues to rotate the adjusting wheel, determining the rotation angle according to requirements. The adjusting wheel drives the adjusting shaft to slide, which in turn drives the adjusting block 133 to slide, thus adjusting the distance between the heating block 131 and the rotating shaft 5, completing the adjustment of the plant spacing.

[0019] The process of laying and perforating the plastic film is as follows: The film roll 10 is unrolled and laid on the electric heating perforation device. After the film contacts the arc-shaped support plate 132, it continues to unfold, passing between the first pressure rod 8 and the second pressure rod 9, and the end is fixed to the ground. The electric heating perforation module 13 is started, and the drive motor 11 is started at the same time. The drive motor 11 drives the rotating shaft 5 to rotate through the driving wheel, the synchronous belt 12 and the driven wheel. During the rotation of the rotating shaft 5, the electric heating block 131 heats and perforates the plastic film. The plastic film continues to flow and unfold under the pull of the ground. The next set of electric heating blocks 131 continues to perform perforation under the drive motor 11, thereby realizing the continuous operation of the plastic film flow unfolding and heating perforation.

[0020] This invention employs a method of perforating before covering with film, avoiding the tearing and misalignment problems caused by mechanical perforation after covering, thus improving the effectiveness of the film. The design of the adjustable drum 137 and adjusting wheels allows for precise adjustment of row and plant spacing, meeting the needs of different crop planting distances and improving the utilization rate of both the film and the land. The coordinated action of the sliding support 135, adjusting block 133, and heating block 131 ensures the efficiency and flexibility of the perforation operation. This invention features a compact and reasonable structural design, is easy to operate, and significantly improves the efficiency and applicability of agricultural film perforation, suitable for the planting needs of various crops.

[0021] In specific applications, this invention can be widely used in mulch film covering technology in modern agricultural production. For example, in vegetable cultivation, operators can quickly adjust the parameters of this device according to the actual plant spacing and row spacing requirements, based on the planting needs of different types of vegetables, to ensure that the distribution of holes on the mulch film conforms to planting specifications. Furthermore, because this device uses electrothermal perforation technology, it can effectively avoid the mulch film damage that may be caused by traditional mechanical perforation, thereby extending the service life of the mulch film and reducing resource waste.

[0022] In summary, this utility model solves many problems existing in current agricultural film perforation devices through innovative mechanical structure design and efficient electrothermal perforation technology, and has significant technical advantages and broad application prospects.

[0023] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
