Description

[0001] The present application relates to the technical field of soil treatment devices, in particular to a seedbed leveling and rolling integrated device of seeding machinery. BACKGROUND

[0002] In the modern agricultural production system, the early stage treatment of the seedbed plays a crucial role in the growth and development of crops. The leveling and rolling of the seedbed, as a key link before seeding, directly affects the germination rate of seeds, root growth and the health of plants in the later stage.

[0003] With the development of agricultural mechanization, some simple mechanical devices have been gradually applied to seedbed treatment work. However, these existing mechanical devices have many limitations. When facing the problem of soil clumping, their processing capacity is seriously insufficient. Larger soil clumps often cannot be effectively broken, so that the soil texture cannot reach the uniform and delicate degree. This is because the design principle of traditional machinery is relatively simple, and there is a lack of targeted breaking structure for soil clumps. For example, some devices only rely on simple rolling or harrowing, which cannot effectively break the internal compact soil clumps. In addition, these traditional devices lack flexibility and adaptability in structural design. They are difficult to effectively adjust and optimize according to different soil conditions (such as clay, sandy soil, etc.) and terrain conditions (such as slope, undulation, etc.). When encountering complex terrain or special soil, not only can they not guarantee the quality of seedbed treatment, but they may even cause mechanical failure, affecting the normal agricultural production process.

[0036] Before the seedbed leveling operation is performed, the operator first checks the overall state of the seeding machine, ensures that each component is firmly connected, and that the key components such as the motor and transmission device can operate normally, confirms that there is no error, starts the seeding machine, and the machine body 1 starts to slowly advance. The roller 3 installed at the advancing end of the machine body 1 starts to rotate under the drive of the motor through a transmission mechanism (such as a belt, chain or gear transmission, etc., which is specifically designed according to the actual design, not shown in the figure). The power of the motor is stably transmitted to the roller 3, which starts to rotate at a set speed, laying the foundation for subsequent soil treatment work.

[0037] Preliminary soil division: After the roller 3 starts to rotate, the multiple groups of division rods 5 fixed on its surface start to rotate together. The inclined tail end of the division rod 5 first cuts into the surface of the seedbed soil. Since the division rods 5 are arranged in a ring shape at equal intervals and the directions of the inclined tail ends are consistent, they act like a small shovel during the rotation of the roller 3, orderly dividing the soil. As the roller 3 rotates, the division rods 5 continuously push the soil in the soil apart. In this process, the larger clumps in the soil cannot be easily moved in the direction of the soil being pushed apart due to their size and weight, and are blocked between the division rods 5. For example, when a larger diameter soil block is encountered, the inclined tail end of the division rod 5 will first contact one side of the soil block. As the roller 3 rotates, a force is generated along the inclined direction of the division rod, trying to push the soil block, but since the soil block is large and is somewhat adhered to the surrounding soil, it will not be easily pushed and will be left in the area between the division rods 5, waiting for further processing.

[0038] Soil clumps enter the roller cavity: As the roller 3 continues to rotate stably, the soil clumps blocked between the division rods 5 move along the straight end direction of the division rods 5. When the soil clumps move to the position of the air gap 301, they will come into contact with the rotating plate 302. At this time, the soil clumps generate a lateral extrusion force on the rotating plate 302. Under the action of this extrusion force, the rotating plate 302 needs to overcome the elastic force of the torsional spring 303 to rotate. The torsional spring 303 is designed to ensure that the rotating plate 302 can maintain the state of closing the air gap 301 when there is no external force, preventing soil particles from entering the hollow cavity of the roller 3 at will. When the extrusion force of the soil clumps is large enough, the rotating plate 302 starts to rotate around its connecting shaft with the roller 3, gradually opening the air gap 301, and the soil clumps enter the hollow cavity of the roller 3 through this open air gap 301. In this process, the soil discharge holes provided on the rotating plate 302 play a role. Some fine soil particles are discharged through the soil discharge holes during the entry of the soil clumps, avoiding the entry of too much fine soil into the roller cavity and affecting the subsequent processing operation of the larger soil clumps.

[0039] It should be noted that the arrangement density of the dislodging rods 5 in this scheme is designed for the common size of soil clods (3-8 cm in diameter) that need to be broken in agricultural production. Multiple sets of dislodging rods 5 are arranged in a ring shape at equal intervals on the outer periphery of the roller 3, and the ring direction included angle of the adjacent two sets of dislodging rods 5 is 15°-20°. The single dislodging rod 5 in each set of dislodging rods 5 is arranged at equal intervals along the axial direction of the roller 3, and the interval is 4-6 cm, which is smaller than the minimum diameter of the target processing clods, so that clods with a diameter greater than 3 cm can be intercepted, and fine soil with a diameter less than 3 cm can pass through. In the extreme case, the ring direction coverage of the adjacent two sets of dislodging rods 5 cooperates with the length of the dislodging rod 5 to form a wrapped interception for clods with a diameter greater than 8 cm.

[0040] The straight end length of the dislodging rod 5 is 8-12 cm, and the arc-shaped guide edge with a curvature radius of 5-8 cm is arranged on the side edge close to the dislodging rod 5 of the rotating plate 302. The torsion spring 303 of the rotating plate 302 is set to have a spring force of 5-8 N. When the soil clod is intercepted between the dislodging rods 5, it will slide along the slightly inclined guide surface of the straight end, be guided by the arc-shaped guide edge at the position of the air gap 301, and when the weight of the clod is greater than 50 g, it can push the rotating plate 302 to pass through the air gap 301 and enter the hollow chamber of the roller 3.

[0041] In-cavity soil clod collision crushing: The soil clods entering the hollow chamber of the roller 3 are in contact and collision with each other in the chamber as the roller rotates continuously. The continuous rotation of the roller 3 makes the soil clods in the chamber in a dynamic state of motion, which constantly changes their positions and directions and frequently collides with each other. Due to the irregular shape of the soil clods, the protruding parts and fragile parts of their surfaces will be impacted first during the collision, and gradually broken into smaller particles. For example, some soil clods with cracks on the surface or uneven texture will have the cracks further expanded after multiple collisions, and finally broken into smaller particles.

[0042] Top rod extrusion crushing: When the roller 3 rotates, the top rod 403 moves up and down along the arc surface of the arc-shaped rod 401, because the arc-shaped rod 401 is fixed on the fixed plate 4, and the fixed plate 4 is fixed relative to the machine body 1. When the roller 3 rotates, the rotating shell 402 moves around the arc-shaped rod 401 with the top rod 403. Due to the arc design of the arc-shaped rod 401, the top rod 403 will produce axial displacement during the movement. When the top rod 403 moves towards the center of the rotating shell 402, the end of the top rod 403 will extrude the soil clods in the chamber. The reset spring on the top rod 403 is compressed when the top rod 403 moves outward under the action of the arc-shaped rod 401, storing elastic potential energy. When the top rod 403 moves to a position where it can be reset along the arc surface of the arc-shaped rod 401, the reset spring releases the elastic potential energy, so that the top rod 403 is reset for the next extrusion action. This periodic extrusion action further breaks the soil clods, making their size continuously decrease.

[0043] Pressing ring auxiliary crushing: the connecting rod 404 moves up and down with the top rod 403, driving the pressing ring 405 to move reciprocatingly horizontally, the extrusion end of the pressing ring 405 matches the surface of the rotating shell 402, and the soil clumps are crushed and pressed during the reciprocating movement, when the top rod 403 moves upward, the pressing ring 405 is driven to move in one direction by the connecting rod 404; when the top rod 403 moves downward, the pressing ring 405 moves in the opposite direction, in this process, the pressing ring 405 will contact and apply pressure to the soil clumps in the cavity, for some relatively small but still relatively compact soil clumps, the pressing action of the pressing ring 405 can effectively further break them up, and the convex mounting rod 406 limits the movement range of the connecting rod 404, ensuring that the pressing ring 405 moves reciprocatingly within a certain trajectory, improving the stability and effectiveness of the crushing and pressing of the soil clumps.

[0044] Soil crushing and discharging: as the roller 3 continues to rotate, the crushed soil particles are discharged from the roller cavity through the soil discharge holes on the rotating plate 302 and other gaps of the roller 3 under the action of gravity and rotational centrifugal force, returning to the surface of the seedbed, when the roller 3 rotates to a certain position, the soil particles in the cavity are affected by the centrifugal force and move to the outside of the roller 3, while the soil discharge holes on the rotating plate 302 and the small gaps that may exist on the wall of the roller 3 provide a discharge channel for these soil particles, the crushed soil returning to the surface of the seedbed further fills the soil voids, making the seedbed soil more uniform and flat, completing the preliminary leveling of the soil.

[0045] After the seedbed is processed by the leveling device, the machine body 1 continues to move forward according to the set route and speed, and the pressing plate 2 installed on the machine body 1 moves accordingly, the shape and size of the pressing plate 2 are designed according to the actual width of the seedbed and the pressing requirements, and it usually has a large planar area to ensure that it can uniformly press the soil of the seedbed, when the pressing plate 2 contacts the soil surface of the leveled seedbed, it presses the soil of the seedbed through its own gravity and the pressure of the machine moving forward, in this process, the pressing plate 2 further compacts the leveled soil, reducing the gap between the soil particles, for example, some relatively loose areas that may exist during the leveling process are pressed more tightly by the soil particles under the action of the pressing plate 2, forming a relatively compact soil layer, which helps to retain soil moisture, reduce water evaporation and loss, and provide a stable soil environment for seed germination, at the same time, the compact soil layer can also prevent the seed from lodging during the subsequent growth process due to the soil being too loose, as the machine body 1 continues to move forward, the pressing plate 2 sequentially presses each area of the seedbed, until the entire seedbed leveling and pressing process is completed.

[0046] The application can block the larger soil clumps between the distribution rods 5 and make them enter the hollow chamber of the roller 3 to collide and crush each other in the process of the rotation of the roller 3, compared with the traditional mode, greatly improves the soil crushing efficiency and effect, makes the soil texture more uniform, and creates good conditions for seed germination.

[0047] The above is only the preferred specific embodiment of the application, but the protection scope of the application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the application within the technical range disclosed by the application, which should be covered in the protection scope of the application.
