Description

Technical Field

[0001] This utility model relates to a high-quality sweet corn tillage device, and in particular to a high-quality sweet corn tillage device, belonging to the field of corn planting technology. Background Technology

[0002] The important role of tillage in agricultural production is that it can transform a certain depth of compacted soil into a loose and fine topsoil layer, thereby increasing soil porosity to facilitate the absorption and storage of rainwater, promote the conversion of potential nutrients in the soil into available nutrients, and encourage the extension of crop roots; it can also turn crop residues, weeds, and fertilizers on the surface into the soil, cleaning the topsoil surface and thus improving the quality of land preparation and sowing.

[0003] During corn cultivation, rotary tillers use high-speed rotating blades to cut the soil, and the resulting impact disrupts the soil's natural granular structure. This granular structure is crucial for soil fertility, effectively retaining moisture and nutrients while enhancing soil aeration. However, long-term rotary tillage can easily lead to soil compaction, forming a hard plow pan, which in turn hinders the downward extension of corn roots and affects the normal growth of the plants.

[0004] Therefore, there is an urgent need to improve a high-quality sweet corn tillage device to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a high-quality sweet corn tillage device that can perform gentle deep tillage, avoiding soil compaction and affecting the normal growth of plants.

[0006] To achieve the above objectives, the main technical solution adopted by this utility model includes: a high-quality fresh sweet corn tillage device, comprising a machine and a power output shaft, mounting plates fixedly installed on corresponding sides of the machine, two turntables rotatably connected between the two mounting plates, universal ball joints fixedly installed on the turntables, rocker arms rotatably connected to the universal ball joints through an adjustable sleeve rod device, both rocker arms being connected to the mounting plates through connecting rods, a shovel plate being provided between the two rocker arms, and a deep loosening shovel fixedly installed at the lower end of the shovel plate;

[0007] The adjustable sleeve includes: a first connecting block, a second connecting block, and a bidirectional threaded rod.

[0008] Preferably, the universal ball joint is located at an off-center position on the turntable.

[0009] Preferably, the first connecting block is threadedly screwed into the universal ball joint, the second connecting block is rotatably connected to the rocker arm, and both the first connecting block and the second connecting block are threadedly screwed into the bidirectional threaded rod.

[0010] Preferably, a drive gear is fixedly mounted on the power output shaft, and the drive gear is meshed with a driven gear.

[0011] Preferably, a connecting shaft is fixedly mounted on the driven gear, and the connecting shaft is fixedly connected to the turntable.

[0012] Preferably, both the driving gear and the driven gear are non-circular gears.

[0013] Preferably, springs are rotatably connected to both ends of the shovel plate, and the end of the spring away from the shovel plate is fixedly connected to the rocker arm.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. When the turntable rotates, it drives the universal ball joint to rotate, which in turn drives the adjustable sleeve device connected to it to rotate. Since one end of the rocker arm is rotatably connected to the connecting rod, and the connecting rod is fixedly connected to the mounting plate, the rotation of the adjustable sleeve device drives the rocker arm to swing back and forth. This causes the shovel plate and the subsoil shovel to swing back and forth, thus using the mechanical force of the subsoil shovel to insert, pry, and lift the soil clods. The gentle force can maintain the soil's granular structure, forming a loose topsoil layer and avoiding soil compaction, which would affect the normal growth of plants.

[0016] 2. By installing a spring between the shovel and the rocker arm, when the shovel tip encounters insurmountable obstacles such as large underground rocks or tree roots, the huge resistance will force the shovel body to rotate around the axis, compressing or twisting the spring, thereby lifting the shovel tip over the obstacle. After the obstacle is overcome, the spring force will reset the shovel body, which effectively prevents the mechanism from getting stuck or damaged. Attached Figure Description

[0023] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] Examples, such as Figures 1-4 As shown, a high-quality sweet corn tillage device includes a machine 1 and a power output shaft 3. Mounting plates 2 are fixedly installed on opposite sides of the machine 1. Two turntables 6 are rotatably connected between the two mounting plates 2. Universal ball joints 8 are fixedly installed on the turntables 6. Rocker arms 12 are rotatably connected to the universal ball joints 8 via an adjustable sleeve device. Both rocker arms 12 are connected to the mounting plates 2 via connecting rods 13. A shovel plate 14 is provided between the two rocker arms 12. A deep loosening shovel 15 is fixedly installed at the lower end of the shovel plate 14. The turntables 6 are rotatably connected between the two mounting plates 2, and the universal ball joints 8 are fixedly installed at an eccentric position on the turntables 6. Simultaneously, the universal ball joints 8 are rotatably connected to the turntables 6 via the adjustable sleeve device. The rocker arm 12 is connected to the turntable 6. When the turntable 6 rotates, it drives the universal ball joint 8 to rotate. When the universal ball joint 8 rotates, it drives the adjustable sleeve device connected to it to rotate. Since one end of the rocker arm 12 is rotatably connected to the connecting rod 13, and the connecting rod 13 is fixedly connected to the mounting plate 2, when the adjustable sleeve device rotates, it drives the rocker arm 12 to swing back and forth. As a result, the shovel plate 14 and the deep loosening shovel 15 are driven by the rocker arm 12 to swing back and forth. The mechanical force of the deep loosening shovel 15 is used to insert, pry, and lift the soil clods. The gentle force can maintain the soil granular structure, form a loose topsoil layer, and avoid soil compaction, which would affect the normal growth of plants.

[0025] The adjustable sleeve includes a first connecting block 9, a second connecting block 11, and a bidirectional threaded rod 10. The universal ball joint 8 is located at the eccentric position of the turntable 6. By setting the adjustable sleeve device, the length of the overall adjustable sleeve can be changed, which will directly change the initial angle of the rocker arm 12, thereby determining the angle of the deep loosening shovel 15 when it enters the soil and the maximum depth that it can reach.

[0026] like Figures 2-3As shown, the first connecting block 9 is threadedly connected to the universal ball joint 8, and the second connecting block 11 is rotatably connected to the rocker arm 12. Both the first connecting block 9 and the second connecting block 11 are threadedly connected to the bidirectional threaded rod 10. By setting the universal ball joint 8 to connect to the first connecting block 9, the first connecting block 9 can rotate slightly, avoiding the device from being too tight and causing the adjustable sleeve device and the rocker arm 12 to break. By setting the bidirectional threaded rod 10, and the threads at both ends of it are opposite, the threads between the first connecting block 9 and the second connecting block 11 are also opposite. When the operator rotates the bidirectional threaded rod 10, the total length of the first connecting block 9, the second connecting block 11 and the bidirectional threaded rod 10 will be adjusted, which will directly change the initial angle of the rocker arm 12.

[0027] like Figures 2-3 As shown, further, a drive gear 4 is fixedly installed on the power output shaft 3, and the drive gear 4 is meshed with a driven gear 5. A connecting shaft 7 is fixedly installed on the driven gear 5, and the connecting shaft 7 is fixedly connected to the turntable 6. Both the drive gear 4 and the driven gear 5 are non-circular gears. By setting the power output shaft 3 and connecting the power output shaft 3 to an external motor, this is existing technology and will not be elaborated here. The drive gear 4 is fixedly installed on the power output shaft 3, and the drive gear 4 is meshed with the driven gear 5. Thus, when the power output shaft 3 rotates, it drives the drive gear 4 to rotate, and the drive gear 4 drives the driven gear 5 to rotate. The connecting shaft 7 is fixedly installed on the driven gear 5, and the connecting shaft 7 is fixedly connected to the turntable 6. Thus, when the driven gear 5 rotates, it drives the connecting shaft 7 to rotate, and the connecting shaft 7 drives the turntable 6 to rotate. At the same time, both ends of the connecting shaft 7 are rotatably connected to the mounting plate 2.

[0028] By setting both the driving gear 4 and the driven gear 5 to be non-circular gears, and as can be seen from the figure, both the driving gear 4 and the driven gear 5 are elliptical gears, making their rotational motion non-uniform. When the deep loosening shovel 15 needs to enter the soil, the driven gear 5 is in the position of driving the short radius with the long radius, thereby obtaining a low speed and a high torque output, achieving slow soil entry. When the deep loosening shovel 15 needs to lift and throw the soil, the driven gear 5 is in the position of driving the long radius with the short radius, thereby obtaining a high speed output, achieving fast soil lifting.

[0029] like Figure 4 As shown, furthermore, springs 16 are rotatably connected to both ends of the shovel plate 14. The end of the spring 16 away from the shovel plate 14 is fixedly connected to the rocker arm 12. By setting the spring 16 between the shovel plate 14 and the rocker arm 12, when the shovel tip encounters insurmountable obstacles such as huge underground rocks or tree roots, the huge resistance will force the shovel body to rotate around the axis, compressing or twisting the spring 16, thereby lifting the shovel tip over the obstacle. After the obstacle is overcome, the elastic force of the spring 16 will reset the shovel body. This effectively prevents the mechanism from being hard-jammed or damaged.

[0030] It should be noted that the spring 16 is subjected to a certain amount of pre-compression or pre-torsion during installation. Under normal working conditions, the resistance of the soil to the shovel plate 14 is much less than the pre-tension of the spring 16. Therefore, the spring 16 is hardly compressed additionally, and the shovel plate 14 is rigidly connected to the rocker arm 12, which is very stable.

[0031] In this embodiment, as Figures 1-4 As shown in the figure, the principle of the high-quality sweet corn tillage device provided in this embodiment is as follows:

[0032] Assuming the mechanism begins a cycle from the deep tillage shovel 15 at its highest point, ready to enter the soil: During smooth entry into the soil (non-circular gear state): the driving gear 4 (long radius) drives the driven gear 5 (short radius), outputting a low speed. Under the traction of the adjustable lever device, the rocker arm 12, centered on the connecting rod 13, slowly and powerfully moves the deep tillage shovel 15 forward and downward. The shovel tip cuts into the soil at a small angle. Due to the slow speed and small impact, it smoothly reaches the maximum tillage depth and cuts off a large clod of soil from the underlying soil. During accelerated lifting (non-circular gear state): the driving gear 4 (radius) begins to drive the driven gear 5 (long radius), and the output speed increases sharply. The movement of the lower end of the rocker arm 12... The direction changes to a rapid upward and backward swing. The deep loosening shovel 15 prys up the entire cut soil clod and accelerates its transport upward and backward. This process overcomes the soil's adhesion, loosening the soil clod. During throwing and falling, the non-circular gear continues to maintain a high speed. The deep loosening shovel 15 reaches the highest point of its trajectory and throws the soil clod out, causing it to fall along the designed parabola into the gap of the rear soil-breaking roller. Subsequently, the shovel body begins to fall forward and upward, preparing for the next soil entry. During the reset preparation, the non-circular gear's state is: the speed gradually decreases, preparing to enter the next low-speed soil entry cycle. The shovel body traces a trajectory in the air and returns to the starting position, preparing for the next work cycle.
