Description

Technical Field

[0001] This utility model relates to the field of garlic planting technology, specifically a linear walking mechanism for garlic planting. Background Technology

[0002] In garlic planting, the performance of the walking mechanism directly affects planting efficiency and adaptability. Traditional walking mechanisms typically employ a fixed-wheel design, which struggles to adapt to complex field environments with varying soil conditions. Fixed wheel blades cannot adjust according to soil hardness, leading to slippage in soft soil and excessive resistance in hard soil, thus affecting travel speed. Furthermore, the fixed-wheel design is inconvenient for normal roadside travel, increasing the overall structural complexity and reducing the equipment's versatility and flexibility. Utility Model Content

[0003] The purpose of this invention is to provide a linear walking mechanism for garlic planting, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a linear walking mechanism for garlic planting, comprising a frame and walking wheels. A main shaft is mounted on the bottom of the frame via clamps, and walking wheels are mounted on both ends of the main shaft. A lead screw is mounted on the center of the outer side of each walking wheel via a bearing. A handwheel is provided at the top of the lead screw, and a movable sleeve is fitted on the lead screw. Each walking wheel includes a fixed wheel connected to the main shaft. Wheel blades are evenly distributed on the outer side of the fixed wheel, and a strip-shaped adjustment groove is provided in the middle of each wheel blade. A movable wheel is provided on the outer side of each wheel blade, and each movable wheel is connected to the movable sleeve via a connecting rod. A transmission wheel one and a transmission wheel two are respectively provided on the main shaft on both sides of the frame, and a planting box is provided on the top of the frame. A planting drum is mounted inside the planting box via a transmission shaft. Both ends of the transmission shaft extend to both sides of the planting box and are respectively equipped with gear one and gear two. A chain is detachably installed between transmission wheel one and gear one, and between transmission wheel two and gear two.

[0005] Preferably, bait blocks 2 are evenly distributed on the outer side of the movable sleeve, and bait block 1 is provided on each movable wheel. Each bait block 1 is connected to each bait block 2 in a one-to-one correspondence through a connecting rod.

[0006] Preferably, both ends of the connecting rod are movably connected to bait block one and bait block two via rotating shafts.

[0007] Preferably, a rotating disk is provided on the outer side of the lead screw near the fixed wheel, and a locking bolt is provided on the rotating disk.

[0008] Preferably, the first transmission wheel and the second transmission wheel have different diameters, and the first gear and the second gear also have different diameters. The first transmission wheel and the first gear are matched with each other, and the second transmission wheel and the second gear are matched with each other.

[0009] Preferably, the first transmission wheel and the second transmission wheel cannot be used for transmission at the same time.

[0010] Preferably, each of the movable wheels is provided with a protective pad on its outer side, and when each of the movable wheels is extended to its maximum distance, the movable wheels form a circular structure with each other.

[0011] This utility model relates to a linear walking mechanism for garlic planting, which has significant advantages and positive effects compared with the prior art, specifically in the following aspects:

[0012] 1. Improve adaptability and flexibility:

[0013] By designing the walking mechanism wheels to be adjustable, this invention allows for flexible adjustment of the blade extension length according to different soil conditions. This design not only enhances the adaptability of the walking mechanism to different soil environments but also effectively addresses the challenges posed by variations in soil looseness and moisture. Compared to the fixed blade design in existing technologies, this invention significantly improves the applicability and working efficiency of the seeder.

[0014] Furthermore, when each movable wheel is extended to its maximum distance, the combination of movable wheels forms a circular structure, which enables good stability and passability when walking on the roadside, avoiding walking difficulties caused by excessively long or short wheel blades. This improves adaptability without increasing the complexity of the overall structure.

[0015] 2. Optimize seeding speed adjustment:

[0016] This invention achieves flexible adjustment of the sowing speed by incorporating gear structures of different diameters on the main shaft, in conjunction with a gear structure connecting the sowing shaft. Users can select different combinations of gears according to actual sowing needs, thereby precisely controlling the sowing speed. This design not only improves the flexibility of sowing operations but also allows for fine-tuning based on crop growth requirements and soil conditions, ensuring sowing quality and efficiency.

[0017] Compared to existing designs with fixed sowing speeds or limited adjustment ranges, this invention offers a wider range of more precise adjustment options, meeting the diverse needs of different users.

[0018] 3. Improve transmission efficiency and stability:

[0019] The design, which utilizes the rotation of the walking mechanism wheels to drive the sowing wheel, simplifies the transmission system, reduces intermediate transmission links, lowers energy loss, and improves transmission efficiency. Simultaneously, this direct transmission method enhances the system's stability and reliability, reducing the probability of malfunctions.

[0020] Existing complex transmission systems not only increase maintenance difficulty and cost, but also easily lead to decreased seeding accuracy due to wear or loosening of transmission components. This invention effectively solves this problem by optimizing the transmission structure.

[0021] 4. Saves costs and resources:

[0022] This invention reduces seed waste and lowers sowing costs by improving the adjustable speed and precision of sowing. Furthermore, its enhanced adaptability reduces repetitive work due to unsuitable soil conditions, further saving manpower and machinery resources.

[0023] Furthermore, simplifying the transmission system also reduces manufacturing and maintenance costs, improving the economic efficiency of the equipment.

[0024] In summary, the linear walking mechanism for garlic planting of this utility model solves the problems of poor adaptability, inconvenient adjustment of planting speed, and low transmission efficiency in the existing technology through innovative design, and has broad application prospects and promotion value.

[0033] The outer side of the movable sleeve 5 is evenly provided with bait blocks 2 13, and each movable wheel 10 is provided with bait block 11. Each bait block 11 is connected to each bait block 2 13 in a one-to-one correspondence through the connecting rod 4.

[0034] Both ends of the connecting rod 4 are movably connected to bait block 11 and bait block 2 13 via pivot 15.

[0035] A rotating disk 8 is provided on the outer side of the lead screw 7 near the fixed wheel 25, and a locking bolt 14 is provided on the rotating disk 8.

[0036] like Figure 1 As shown, the frame 1 is made of high-strength steel and has good load-bearing capacity. The clamps are fastened with bolts to ensure a firm and reliable connection between the spindle 2 and the frame 1. The spindle 2 is made of wear-resistant material to ensure that it will not deform during long-term use.

[0037] Two traveling wheels 3 are mounted at each end of the main shaft 2. The traveling wheels 3 have good wear resistance and shock absorption performance. Each traveling wheel 3 is connected to the main shaft 2 through a bearing to ensure that the traveling wheel 3 can rotate flexibly.

[0038] A lead screw 7 is mounted on the center of the outer side of the traveling wheel 3 via a bearing. The lead screw 7 is made of a high-precision threaded rod to ensure adjustment accuracy. A handwheel 6 is located at the top of the lead screw 7. The handwheel 6 is made of a comfortable grip material, allowing the user to easily adjust the position of the lead screw 7 manually.

[0039] A movable sleeve 5 is fitted onto the lead screw 7. The movable sleeve 5 is made of sliding bearing material to ensure smooth sliding on the lead screw 7. Bait blocks 13 are evenly distributed on the outer side of the movable sleeve 5. The bait blocks 13 have good wear resistance and impact resistance.

[0040] The traveling wheel 3 includes a fixed wheel 25 connected to the main shaft 2. Wheel blades 17 are evenly distributed on the outer side of the fixed wheel 25. These wheel blades 17 are made of hard alloy material, possessing extremely high wear resistance and cutting performance. A strip-shaped adjustment groove 18 is provided in the middle of each wheel blade 17. The strip-shaped adjustment groove 18 is used to adjust the position of the wheel blade 17 to adapt to different road conditions.

[0041] Each wheel blade 17 has a movable wheel 10 on its outer side. The movable wheel 10 is made of the same material as the traveling wheel 3 to ensure consistent performance. Each movable wheel 10 is connected to the movable sleeve 5 via a connecting rod 4. Both ends of the connecting rod 4 are movably connected to bait block 11 and bait block 2 13 via pivots 15, ensuring that the movable wheel 10 can be flexibly adjusted as the movable sleeve 5 moves.

[0042] Each movable wheel 10 is equipped with a bait block 11. The bait block 11 is connected to each bait block 2 13 in a one-to-one correspondence via a connecting rod 4. The bait blocks 11 and 2 13 are made of the same material to ensure consistent performance.

[0043] A rotating disk 8 is provided on the outer side of the lead screw 7 near the fixed wheel 25. The rotating disk 8 is made of high-strength aluminum alloy, which has good corrosion resistance and lightweight characteristics. A locking bolt 14 is provided on the rotating disk 8. The locking bolt 14 is made of stainless steel to ensure that it will not rust during long-term use.

[0044] The main shafts 2 on both sides of the frame 1 are respectively equipped with a first drive wheel 9 and a second drive wheel 12, and the top of the frame 1 is equipped with a seeding box 19. The seeding box 19 is equipped with a seeding drum 24 through a drive shaft 23. The two ends of the drive shaft 23 extend to the two sides of the seeding box 19 and are respectively equipped with a first gear 20 and a second gear 21. A chain 22 is detachably installed between the first drive wheel 9 and the first gear 20, and between the second drive wheel 12 and the second gear 21.

[0045] The diameters of transmission wheel 19 and transmission wheel 212 are different, and the diameters of gear 120 and gear 21 are also different. Transmission wheel 19 and gear 120 are matched with each other, and transmission wheel 212 and gear 21 are matched with each other.

[0046] Transmission wheel 9 and transmission wheel 12 cannot be used for transmission at the same time.

[0047] Each movable wheel 10 is provided with a protective pad 16 on its outer side, and when each movable wheel 10 is extended to its maximum distance, the movable wheels 10 form a circular structure with each other.

[0048] The frame 1 is the basic structure of this device and is made of high-strength steel to ensure overall stability. Main shafts 2 are located on both sides of the frame 1, and drive wheels 9 and 12 are mounted on the main shafts 2. Drive wheels 9 and 12 have different diameters and are used for different transmission requirements.

[0049] Transmission wheel 9 and gear 20 are connected by chain 22, and transmission wheel 12 and gear 21 are also connected by chain 22. Chain 22 is made of high-strength wear-resistant material to ensure stability and durability during transmission. The chains 22 between transmission wheel 9 and gear 20, and between transmission wheel 12 and gear 21, are detachable for easy maintenance and replacement.

[0050] The top of the frame 1 is equipped with a seeding box 19, which is made of waterproof and dustproof material. Inside the seeding box 19, a seeding drum 24 is installed via a drive shaft 23. The two ends of the drive shaft 23 extend to both sides of the seeding box 19, and gear 1 20 and gear 2 21 are respectively installed thereon. Gear 1 20 and gear 2 21 have different diameters and are matched with drive wheel 1 9 and drive wheel 2 12, respectively.

[0051] Transmission wheel 9 and transmission wheel 12 have different diameters and are used for different transmission requirements. Transmission wheel 9 is matched with gear 20, and transmission wheel 12 is matched with gear 21. Specifically, transmission wheel 9 has a larger diameter and is suitable for low-speed, high-torque transmission requirements; transmission wheel 12 has a smaller diameter and is suitable for high-speed, low-torque transmission requirements.

[0052] Transmission wheel 9 and transmission wheel 12 cannot be used simultaneously. By switching the installation position of chain 22, different transmission modes can be achieved to meet different sowing needs.

[0053] Each movable wheel 10 is provided with a protective pad 16 on its outer side. The protective pad 16 is made of high-strength rubber material, which has good wear resistance and cushioning performance, and can effectively protect the movable wheel 10 from damage during driving.

[0054] When each movable wheel 10 is extended to its maximum distance, the movable wheels 10 form a circular structure with each other. This design not only improves the stability of the device but also allows for flexible movement in complex terrain. The extension and retraction of the movable wheels 10 are achieved by manually turning the lead screw 7, making operation simple.

[0055] In this embodiment, during normal road travel, the handwheel 6 rotates the lead screw 7, causing the movable sleeve 5 to move forward. This, in turn, moves the movable wheel 10 forward along the wheel blade 17 via the connecting rod 4. When the movable sleeve 5 reaches its highest point, the movable wheel 10 just covers the top of the wheel blade 17. The locking bolt 14 is used to fix the position of the rotating disk 8, thus restricting the rotation of the lead screw 7. At this time, multiple movable wheels 10 combine to form a circular structure, facilitating the movement of the frame 1 on normal roads. When traveling to a sowing field, the locking bolt 14 is loosened, and the handwheel 6 is rotated in the opposite direction, causing the lead screw 7 to rotate. At this time, the movable sleeve 5 moves towards one end of the lead screw 7, thereby pulling the movable wheel 10 forward via the connecting rod 4, exposing the wheel blade 17, facilitating movement in the sowing field. Under the same soil conditions, the distance between the movable sleeve 5 and the lead screw 7 is adjusted to flexibly adjust the extension length of the wheel blade 17, so that the walking wheel 3 maintains good stability and passability, avoiding walking difficulties caused by the wheel blade being too long or too short. The position of the rotating disk 8 is fixed by the locking bolt 14, thereby fixing the extension length of the wheel blade 17. According to the sowing needs, the transmission wheel 12 and gear 21 are connected by the chain 22, or the transmission wheel 9 and gear 20 are connected by the chain 22. When the walking wheel 3 moves, it drives the main shaft 2 to rotate, which drives the gear 21 to rotate through the transmission wheel 12 and the chain 22, or drives the gear 20 to rotate through the transmission wheel 9 and the chain 22, thereby driving the sowing drum 24 to rotate, so as to evenly sow the seeds inside the sowing box 19.

[0056] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
