Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mulch film covering technology, specifically relating to a melon mulch film covering device. Background Technology
[0002] In agricultural planting, mulching technology is a widely used and highly effective technique. By laying mulch on the soil surface, it effectively regulates soil temperature and humidity, suppresses weed growth, reduces water evaporation, and creates more favorable environmental conditions for crop growth, thereby improving crop yield and quality. Currently, there are various mulching devices on the market, which mainly consist of a frame, a film-hanging mechanism mounted on the frame, and a soil-covering mechanism.
[0003] The frame, as the main supporting structure of the equipment, typically employs an adjustable-width frame structure paired with wheels. The film-laying mechanism is responsible for installing the mulch film rolls. As the frame moves across the field, it lays the mulch film, laying the foundation for subsequent agricultural production. The soil-covering mechanism generally includes a soil-covering plate and connecting rods. During the frame's movement, the soil-covering plate cuts the soil and guides the soil clods to rise and turn over to the edge of the mulch film, thus achieving full-line coverage. This full-line coverage method ensures the mulch film's stability to a certain extent and is well-suited for large-scale planting of crops such as wheat and corn, or for growing vegetables and flowers in greenhouses—crops with high temperature and humidity requirements.
[0004] However, existing plastic film mulching systems have significant limitations for crops with specific growth characteristics, such as melons. Melons have relatively shallow root systems and require high soil aeration. Full-coverage mulching severely restricts airflow between the film and the soil, leading to reduced soil oxygen levels. In an oxygen-deficient environment, melon roots experience severely impaired respiration, affecting their ability to absorb nutrients and water. This not only inhibits the growth and development of melon plants but can also lead to decreased yield and poorer quality. For example, in prolonged oxygen-deficient environments, melon plants are prone to yellowing leaves, slow growth, and poor fruit development.
[0005] Furthermore, existing plastic film mulching devices lack the ability to space soil coverage, making it impossible to flexibly adjust the soil covering method according to the growth needs of crops such as melons. This results in poor applicability of the devices, making it difficult to meet the diverse needs of agricultural production. Summary of the Invention
[0006] To address the above problems, the purpose of this utility model is to provide a melon mulch covering device to solve the problems mentioned in the background art.
[0007] This utility model provides a cantaloupe mulch covering device, comprising: a frame, consisting of an adjustable-width frame structure and wheels, serving as the main support structure of the device; a film hanging mechanism, mounted on the frame, for installing mulch rolls; a soil covering mechanism, including a soil covering plate for covering soil onto the edge of the laid mulch when the frame moves, and a connecting rod for mounting the soil covering plate on the frame; and a spacing adjustment mechanism connected to the soil covering mechanism for adjusting the spacing of the soil covering, the spacing adjustment mechanism including: a crossbar, rotatably connected to the frame structure, for installing and supporting the connecting rod;
[0008] A power component, connected to the crossbar, is used to drive the crossbar to reciprocate and rotate to dynamically adjust the distance between the soil covering board and the ground, thereby achieving intermittent soil covering of the mulch film.
[0009] Preferably, it also includes a controller, which is electrically connected to the power component and is used to control the operating parameters of the power component according to a preset program.
[0010] Preferably, the film-attaching mechanism includes: two first telescopic rods, which are installed opposite each other on both sides of the frame structure to adjust the height of the film-attaching mechanism; a hanging plate installed at the bottom end of the first telescopic rods, with a mounting groove through the middle for installing the film roll, and an end cap for fixing the film roll is threaded to the outer side of the hanging plate.
[0011] Preferably, the crossbar includes: a sleeve installed at one end of the frame structure; and a sleeve rod disposed opposite to and slidably connected to the sleeve, wherein the distance between the two soil covering plates is adjusted by adjusting the length of the sleeve extending into the sleeve, and a locking element for locking the relative position of the sleeve and the sleeve rod is provided between the sleeve and the sleeve rod.
[0012] Preferably, it also includes a film pressing mechanism, which is located between the soil covering mechanism and the film hanging mechanism, for pressing the film flat on the ground. The film pressing mechanism includes: two second telescopic rods, which are installed opposite each other on both sides of the frame structure for adjusting the height of the film pressing mechanism; and a film pressing wheel, which is installed at the bottom end of the second telescopic rods for pressing the film rolled out from the ground flat on the ground.
[0013] Preferably, the frame is also provided with a handrail, and the surface of the handrail is provided with an anti-slip sleeve to facilitate the operator to push the device.
[0014] The beneficial effects of this invention are as follows: By connecting the soil covering mechanism with the spacing adjustment mechanism, this invention can dynamically adjust the distance between the soil covering plate and the ground, thereby achieving precise adjustment of the soil covering spacing. While ensuring the basic fixation of the mulch film, it increases soil permeability, provides sufficient oxygen for the melon roots, promotes healthy root growth, and thus improves the yield and quality of melons. It can also meet the needs of different planting scenarios, offering both mulch film soil spacing coverage and full-line coverage modes.
[0015] In addition, the local film covering device can adapt to covering films of different widths by setting up an adjustable-width frame and a soil covering mechanism. At the same time, it can adapt to laying films of different thicknesses and different terrains by setting up an adjustable-height film hanging mechanism and a film pressing mechanism.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.
[0024] The existing plastic film mulching device of this utility model mainly includes a frame 1, a film-hanging mechanism 4 and a soil-covering mechanism 5 mounted on the frame 1. The frame 1 is composed of an adjustable-width frame structure 2 and traveling wheels 3, serving as the main support structure of the device, capable of accommodating mulch films of different widths. The film-hanging mechanism 4 is used to install the mulch film roll 13. As the frame 1 moves, the mulch film is laid. After the mulch film is laid, the soil-covering mechanism 5 is needed to cover the edges of the mulch film with soil. Existing plastic film mulching devices only achieve full-line coverage. When the connecting rod 7 is installed on the frame 1 during use, As the frame 1 moves, the soil covering plate 6 cuts the soil and guides the soil clods to rise and turn over to the edge of the mulch film. Although full-line coverage is relatively firm, it is mainly suitable for large-scale planting of crops such as wheat or corn, or for planting vegetables, flowers and other crops with high requirements for temperature and humidity in greenhouses. However, for crops such as melons with shallow roots and high requirements for soil aeration, intermittent soil covering can increase soil aeration while ensuring the mulch film is fixed. The existing mulch film covering device does not have the function of intermittent soil covering and has poor applicability. The above is the existing mulch film covering device.
[0025] Based on the above problems, the present invention adopts the following improvement method to solve them.
[0026] like Figure 1-6 As shown, a melon mulch covering device, based on existing technology, is equipped with a spacing adjustment mechanism connected to a soil covering mechanism 5. This mechanism adjusts the spacing of the soil covering. The spacing adjustment mechanism includes a crossbar 8 rotatably connected to a frame structure 2 for mounting and supporting connecting rods 7, and a power component 9 connected to the crossbar 8 for driving the crossbar 8 to reciprocate and dynamically adjust the distance between the soil covering plate 6 and the ground, thus achieving the spaced soil covering of the mulch. Figure 2As shown, the power unit 9 can be a high-precision device such as a servo motor or a stepper motor. To improve the automation level of the local film covering device, a controller 10 is also installed, which is electrically connected to the power unit 9. The controller 10 controls the operating parameters of the power unit 9 according to a preset program. When covering the soil at intervals, the operating parameters of the power unit 9 are selected in advance on the buttons or touch screen on the controller 10, such as at least one of rotation speed, rotation angle, and rotation cycle. In this technical solution, the rotation angle of the power unit 9 is controlled within the range of 0-90 degrees. In the use state, the connecting rod 7 and the soil covering plate 6 are perpendicular to the ground. At this time, the power unit 9 rotates 90 degrees in the forward direction. As the worker applies traction force to the handrail 23 on the frame 1, the entire device is driven to move, so that the soil covering... The cover plate 6 can cut the soil. When not in use, the power component 9 rotates in the opposite direction by 45-90 degrees, driving the crossbar 8 and connecting rod 7 to rotate counterclockwise to the side away from the film-hanging mechanism 4, so that the cover plate 6 does not contact the ground. This process is repeated. The size of the soil covering spacing can be controlled by adjusting the rotation speed or rotation cycle of the power component 9. However, for the manually driven method, the soil covering spacing may be uneven, but this does not affect the use. The main difference between full-line soil covering and spaced soil covering is that full-line soil covering leaves no gaps, while spaced soil covering leaves gaps for plant respiration. Of course, in practical applications, an engine or other means can be used to drive the walking wheels 3 to overcome the difficulty of manually driving the device. During full-line soil covering, the power component 9 controls the cover plate 6 to always be perpendicular to the soil. The controller 10 also has a manual adjustment mode and an automatic adjustment mode. In the manual adjustment mode, the operator can directly input the operating parameters through the control panel; in the automatic adjustment mode, the controller 10 can automatically adjust the operating parameters according to the preset crop planting mode or soil conditions. Figure 1-2 As shown, the soil covering board 6 adopts a plow (including plowshare and plowshare). The plowshare can cut into the soil and lift up the soil mound, and the plowshare can further break up and turn the soil mound lifted by the plowshare to the edge of the mulch film.
[0027] The film-laying mechanism 4, which is capable of releasing the mulch film, mainly consists of two first telescopic rods 11 installed opposite each other on both sides of the frame structure 2 and a hanging plate 12 installed at the bottom of the first telescopic rods 11. The middle of the hanging plate 12 is provided with an installation groove 21, which is used to install the mulch film roll 13. The outer side of the hanging plate 12 is threaded with an end cap 22 for fixing the mulch film roll 13. Specifically, when the two ends of the mulch film roll 13 are inserted into the installation groove 21 on the hanging plate 12, the end cap 22 is screwed onto the two ends of the mulch film roll 13 and abuts against the outer walls on both sides of the hanging plate 12 to fix the mulch film roll 13. As the frame 1 moves, the mulch film is laid on the melon ground. To facilitate the application of soil from the covering board 6 to the edge of the mulch film, a pressing mechanism 16 is added. Located between the covering mechanism 5 and the film hanging mechanism 4, it is mainly used to flatten the mulch film on the ground. It mainly includes two second telescopic rods 17 installed opposite each other on both sides of the frame structure 2 for adjusting the height of the pressing mechanism 16, and a pressing wheel 18 installed at the bottom of the second telescopic rods 17 for flattening the mulch film released from the mulch film roll 13 onto the ground. The pressing wheel 18 is usually made of soft materials, such as rubber wheels or foam plastic wheels, to prevent scratching the mulch film during pressing. At the same time, the pressing wheel 18 has anti-slip texture on its surface and a hollow internal structure to reduce weight. The pressing wheel 18 is installed at the bottom of the second telescopic rod 17 through bearings and can rotate freely to reduce resistance during mulch film laying. (Regarding the first telescopic rod 11 and the second telescopic rod 17 in this utility model, their functions are to adjust the height of the film-attaching mechanism 4 and the film-pressing mechanism 16, respectively. Their common feature is that they are telescopic; they can be automatically adjusted, such as an electric telescopic rod, or manually adjusted, such as a crossbar 8. It mainly includes a sleeve 14 installed at one end of the frame structure 2 and a sleeve rod 15 opposite to and slidably connected to the sleeve 14. Both the sleeve 14 and the sleeve rod 15 are parallel to the ground. The distance between the two soil-covering plates 6 is adjusted by adjusting the length of the sleeve rod 15 extending into the sleeve 14. A locking element for locking the relative position of the sleeve 14 and the sleeve rod 15 is provided between them. The locking element can be a bolt 19, which is installed on the sleeve 14. Multiple adjustment holes 20 are evenly opened on the sleeve rod 15. By adjusting the width of the sleeve rod 15 inserted into the sleeve 14, the length of the crossbar 8 is adjusted, thereby adapting to the width of the frame 1. Specifically, regarding the first telescopic rod 11 and the second telescopic rod 17, as...) Figure 2 As shown, sleeve 14 is installed at the bottom of frame structure 2, while both sleeve rod 15 and sleeve 14 are perpendicular to the ground. The locking mechanism for sleeve 14 and sleeve rod 15 is the same as that for crossbar 8. Figure 1-2As shown, the frame structure 2 consists of two opposing trusses and two members respectively installed on the two trusses. One member has a slot that matches the other member, and the member without a slot has multiple adjustment holes 20. The member with the slot is fixed to the other member by locking bolts 19, thereby realizing the width adjustment of the frame 1.
