Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a miniature sweet and crisp corn planting, fertilizing and mulching machine. Background Technology

[0002] In modern agricultural production, especially for cash crops such as sweet and crisp corn, the use of agricultural film mulching technology is an important means to ensure increased crop yield, moisture retention, temperature increase, and weed control. In order to improve agricultural operation efficiency and reduce labor costs, sowing, fertilizing, and mulching machines that integrate sowing, fertilizing, and mulching functions have been widely used.

[0003] However, existing mulching machines, especially miniature machines, generally have prominent problems in actual operation, particularly when operating in hilly or uneven fields. The soil surface of farmland is difficult to make completely level, often resulting in unevenness or clods.

[0004] When the laminating machine travels on these uneven surfaces, the pressure rollers used to compact the film mostly employ rigid connections or simple elastic structures. When encountering ground protrusions, this structure generates a rigid impact on the pressure rollers, which is instantly transmitted to the film being laid, potentially causing the film to break or tear. Conversely, when encountering depressions, the pressure rollers may be suspended or lack sufficient pressure, resulting in the film failing to adhere tightly to the ground, leading to poor laying quality and weak wind resistance.

[0005] The core problem of uneven ground causing damage to the film and poor laying quality seriously affects the actual effect of mulched cultivation and the operational reliability of agricultural machinery.

[0006] Therefore, this utility model proposes a miniature sweet and crisp corn planting, fertilizing, and mulching machine to address the shortcomings of existing technologies. Utility Model Content

[0007] In view of the problems existing in the prior art, such as the fact that the pressing rollers of a mini sweet and crisp corn planting, fertilizing and mulching machine are mostly rigidly connected when operating on uneven ground, making the film easy to be torn or broken due to ground impact, and the poor laying quality and insufficient adaptability to complex terrain, this utility model aims to provide a mini sweet and crisp corn planting, fertilizing and mulching machine with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a miniature sweet and crisp corn planting, fertilizing and mulching machine, including: a machine body, a film feeding mechanism, a soil covering and film pressing mechanism, a planting pipe and a fertilizing pipe; the film feeding mechanism includes a roller, a hydraulic rod and a long plate, the soil covering and film pressing mechanism includes a rubber wheel, a piston and a fixed arm, both the planting pipe and the fertilizing pipe are connected to a soil covering plate, and the soil covering and film pressing mechanism is also connected to a soil sealing plate.

[0009] Among them, the soil covering and pressing mechanism is the key to realizing the core function of this utility model. Its fixed arm is fixedly connected to the lower rear of the machine body, and the rubber wheel is rotatably set at the lower end of the fixed arm through a rotating bracket. The film passes through the bottom of the rubber wheel to compact it.

[0010] Furthermore, the body, the soil covering and pressing mechanism, and the piston are combined through a unique buffer structure. One end of the piston is rotatably connected to the rotating bracket, and the other end of the piston is rotatably connected to the fixed arm. The piston provides effective buffering force for the vertical movement of the rubber wheel relative to the fixed arm, thereby actively adapting to changes in ground height and absorbing the impact caused by uneven ground.

[0011] In addition, the film feeding mechanism has radial guide grooves on its roll, and a long plate is slidably set in the guide grooves. One end of the hydraulic rod is fixedly connected to the long plate and is used to drive the long plate to move radially along the guide grooves in order to precisely adjust the tension applied to the film. At the same time, the soil covering plate is fixedly connected to the rear side of the seeding pipe and the rear side of the fertilizer pipe, and the soil sealing plate is fixedly connected to the fixed arm and is located behind the soil covering plate, forming a graded soil covering structure.

[0012] Preferably, the film feeding mechanism further includes a fixed rod and a connecting rod. The roll and the fixed rod are coaxially sleeved on the connecting rod. A fixed plate is fixedly connected to the top of the connecting rod. Rotating rods are rotatably connected to the upper middle parts of the left and right ends of the fixed plate. The fixed rod rotates synchronously with the roll. This structure provides a reliable foundation support for the stable rotation of the roll. The rotating rod rotates in the opposite direction to the roll, which can press down the film and prevent the film from becoming loose, thus ensuring a smooth film feeding process.

[0013] Preferably, the film feeding mechanism further includes a fixing block, which is used to fix the fixing rod to the roll, and the roll is provided with the guide groove so that the long plate can slide accurately. This design not only realizes the reliable fixation of the components, but also provides a guiding basis for the precise movement of the tension adjustment mechanism.

[0014] Preferably, the film feeding mechanism further includes a limiting plate, which is fixedly connected to one end of the fixing rod to prevent the fixing rod from axially falling off the connecting rod. This simple structural design greatly enhances the structural stability and safety of the film feeding mechanism in complex operating environments.

[0015] Preferably, the film feeding mechanism further includes a friction pad, which is fixedly attached to the outer peripheral surface of the roll. By increasing the friction between the film and the roll surface, the friction pad effectively prevents the film from slipping due to tension changes or machine vibrations during the conveying process, thus ensuring the continuity and stability of film feeding.

[0016] Preferably, the soil covering and pressing mechanism further includes a fixed shaft and a support block. The rubber wheel is rotatably connected to the fixed shaft, and both ends of the fixed shaft are fixedly connected to the rotating bracket through the support block. The structure provides a stable installation foundation for the reliable rotation of the rubber wheel, ensuring the effective execution of the pressing operation.

[0017] Preferably, as a specific connection method, one end of the piston is rotatably connected to the support block, and the other end of the piston is rotatably connected to the fixed arm. This scheme clarifies the transmission path of the buffer force, making the mechanical structure clearer and the overall design more compact and reliable.

[0018] Preferably, the soil covering and pressing mechanism further includes a second limiting plate, which is fixedly connected to the connection between the fixed arm and the machine body to prevent the fixed arm from loosening or falling off due to vibration or accidental impact caused by long-term operation, thereby improving the safety of the connection of key components of the whole machine.

[0019] Preferably, to optimize the synergistic effect of soil covering and sealing, the soil covering plate is a V-shaped scraper integrally formed and fixedly connected to the rear side of the seeding pipe and the fertilizer application pipe, and the soil sealing plate is a flat scraper set in front of the rubber wheel. Through the functional cooperation of scrapers of different shapes, more efficient and flatter covering and sealing operations for seeds and fertilizers can be achieved.

[0020] This utility model has the following beneficial effects: 1. This utility model solves the problems of low efficiency, cumbersome procedures, and poor soil covering effect in the existing technology of integrated sowing, fertilization, and mulching operations by arranging the sowing tube and fertilization tube alternately in front and behind, and equipping the sowing tube and fertilization tube with soil covering plates respectively, and setting a soil sealing plate at the rear for secondary soil sealing. It achieves the technical effect of completing sowing, fertilization, primary soil covering and secondary soil sealing in one operation, which significantly improves the operation efficiency and soil covering quality.

[0021] 2. This utility model solves the problem in the prior art where the pressing wheel causes rigid impact to the film when encountering uneven soil, which easily damages or tears the film. It achieves the technical effect of buffering and shock absorption. When the rubber wheel is lifted, the piston absorbs the impact force, effectively protecting the film and enhancing the machine's adaptability to complex terrain.

[0022] 3. This utility model solves the problems of inconvenient film tension adjustment and difficulty in adapting to films of different thicknesses in the prior art by setting a hydraulic rod to drive the long plate in the film feeding mechanism and making the long plate move radially in the guide groove of the roll, while the rotating rod can restrict the loosening of the film. It achieves the technical effect of flexibly and accurately adjusting the film tension, ensuring the flatness and adhesion of the film during the laying process, and improving the film coating quality and wind resistance.

[0023] 4. This utility model solves the problems of film slippage during conveying and insufficient connection stability of key components in the prior art by setting friction pads on the outer circumferential surface of the roll and setting limit plate one and limit plate two on the fixed rod and fixed arm respectively. It achieves the technical effects of preventing film from falling off, ensuring film feeding stability, and improving the overall structural reliability of the machine. Attached Figure Description

In a preferred embodiment, in order to achieve a reliable connection between the fixing rod 201 and the roll 207 and to provide guidance for the long plate 205, the film feeding mechanism 2 also includes a fixing block 206. The fixing block 206 is used to fix the fixing rod 201 and the roll 207, and a guide groove is provided on the fixing block 206 to allow the long plate 205 to slide accurately.

In a preferred embodiment, in order to achieve reliable rotational installation of the rubber wheel 301, the soil covering and pressing mechanism 3 further includes a fixed shaft 302 and a support block 303. The rubber wheel 301 is rotatably connected to the fixed shaft 302, and both ends of the fixed shaft 302 are fixedly connected to the rotating bracket through the support block 303. In a preferred embodiment, to further clarify the buffer connection path of piston 304, one end of piston 304 is rotatably connected to support block 303, and the other end of piston 304 is rotatably connected to fixed arm 305. As a preferred embodiment, in order to improve the installation stability of the fixed arm 305, the soil covering and pressing mechanism 3 also includes a second limiting plate 307, which is fixedly connected to the connection between the fixed arm 305 and the machine body 1 to prevent the fixed arm 305 from falling off. As a preferred embodiment, in order to optimize the specific effects of covering and sealing the soil, the covering plate 308 is a V-shaped scraper that is integrally formed and fixedly connected to the rear side of the seeding pipe 5 and the fertilizer pipe 4, and the sealing plate 306 is a flat scraper that is set in front of the rubber wheel 301.

[0036] Working principle: The machine moves forward under traction. The corn seeds and fertilizer inside the machine body 1 are vertically fixed to the bottom of the machine body 1 through the sowing pipe 5 and the fertilizer pipe 4 respectively and fall into the soil. Since the fertilizer pipe 4 and the sowing pipe 5 are arranged alternately, the sowing and fertilization are carried out simultaneously. After the seeds and fertilizer fall, the soil covering plate 308 fixedly connected to the rear side of the sowing pipe 5 and the fertilizer pipe 4 first covers the soil, and then the soil sealing plate 306 fixedly connected to the fixed arm 305 performs a second soil sealing. While sowing and covering with soil, the film feeding mechanism 2 starts working. As the machine moves forward, the film is pulled out. The pulling force drives the drum 207 and the fixed rod 201 to rotate synchronously on the connecting rod 208. The fixed block 206 ensures the synchronous rotation of the fixed rod 201 and the drum 207. The limit plate 202 prevents the fixed rod 201 from falling off. At this time, the hydraulic rod 203 is activated. The hydraulic rod 203 drives the long plate 205 to move radially in the guide groove, applying pressure to the film on the drum 207. A fixed plate 209 is fixed on the connecting rod 208. A rotating rod 210 is rotatably connected to the fixed plate 209. The space between the rotating rod 210 and the drum 207 is used to place the film. The rotating rod 210 can prevent the film from loosening and realize the tension adjustment of films of different thicknesses. The friction pad 204 increases the friction of the film on the drum 207 and prevents the film from falling off. The released film passes through the bottom of the rubber wheel 301 of the soil covering and pressing mechanism 3. The rubber wheel 301 rotates under the support of the fixed shaft 302 and the support block 303, compacting the film and making it adhere to the ground, thus improving the film covering effect in windy conditions. When the machine encounters uneven ground caused by different soil heights during its movement, the rubber wheel 301, along with its rotating bracket and support block 303, will be lifted up. The rotating bracket or support block 303 is rotatably connected to one end of the piston 304, and the other end of the piston 304 is rotatably connected to the fixed arm 305. Therefore, the piston 304 can provide buffering force for the bumps of the rubber wheel 301, absorb the impact, and prevent the film from being damaged. The fixed arm 305 supports the entire pressing assembly, and the limiting plate 307 ensures that the fixed arm 305 is installed securely.
