Description

Technical Field

[0001] This utility model relates to the field of agricultural implements technology, specifically a corn seedling transplanting device. Background Technology

[0002] Corn is one of the world's most important crops, widely cultivated around the globe. Corn cultivation methods include direct sowing and transplanting, with transplanting being widely used in some regions, especially where land conditions are complex or where optimized seedling growth environments are required. However, while existing corn seedling transplanting shovels are widely used due to their simple structure, low cost, and ease of operation, some significant problems remain, particularly in the soil removal process, which urgently requires further improvement.

[0003] Traditional corn seedling transplanting shovels typically consist of a shovel blade, a handle, and some auxiliary devices. Their main function is to remove corn seedlings from the seedbed and transplant them to the designated location. Although the tool has a relatively simple structure, it has revealed some shortcomings in practical use, particularly in the efficiency and comfort of removing the soil. Removing the soil refers to the process of cleaning the soil attached to the roots of the corn seedlings. The efficiency and accuracy of this step directly affect the survival rate of the corn seedlings; therefore, improving the ease and efficiency of this process is of great significance for improving the overall effect of corn transplanting.

[0004] Traditional corn seedling transplanting shovels lack specific ergonomic considerations in their design. The shape of the soil-removing components and the handle design are mostly focused on ease of use, neglecting the potential labor intensity and tediousness of operation. Specifically, users often need to exert considerable force to remove the soil around the seedling roots, which can lead to hand or back fatigue, and even discomfort or injury. Furthermore, traditional transplanting shovels typically lack adaptability; operators may face different challenges depending on soil type and moisture conditions, resulting in low transplanting efficiency.

[0020] Example

[0021] The following is combined Figures 1 to 3 This application introduces a corn seedling transplanting device, including a handle 3, a connecting rod 2, a ring shovel 1, and a soil-removing ring 6. The lower end of the handle 3 is connected to the connecting rod 2, and the lower end of the connecting rod 2 is connected to the ring shovel 1. The ring soil-removing ring 6 is slidably installed in the inner wall of the ring shovel 1, and the upper end of the soil-removing ring 6 is connected to a sliding rod 7 that slides linearly along the connecting rod 2. The device is characterized by having a semi-automatic soil-removing locking unit jointly provided on the sliding rod 7 and the connecting rod 2. The semi-automatic soil-removing locking unit is used to lock the soil-removing ring 6 to the inner top wall of the ring shovel 1 during the transplanting process.

[0022] The semi-automatic soil-removing locking unit includes a handle 9, an unlocking rod 10, a rotating component 12, a hook 11, and a wedge 13. The handle 9 is rotatably connected to the handle 3. One end of the handle 9 is connected to the unlocking rod 10, which is parallel to the connecting rod 2. The rotation of the handle 9 causes the unlocking rod 10 to slide parallel to the axis of the connecting rod 2. The end of the connecting rod 2 near the ring shovel 1 is rotatably connected to the hook 11 via the rotating component 12. The lower end of the unlocking rod 10 is hinged to the hook 11. The top of the sliding rod 7 has a wedge 13 that engages with the hook 11. The wedge 13 has a locking groove 14 that engages with the end of the hook 11. A spring with a spring force that pushes the sliding rod 7 towards the ring shovel 1 is provided between the sliding rod 7 and the connecting rod 2, thereby maintaining close contact of the soil-removing ring 6, effectively ensuring stability during transplanting and reducing the play in the soil-removing ring 6.

[0023] The lower end of the ring shovel 1 is provided with a ring-shaped cone 5 to increase the soil breaking efficiency, which can enhance the soil breaking ability of the shovel, so that even in hard or compact soil, the transplanting shovel can efficiently complete the soil penetration and improve the overall soil breaking efficiency.

[0024] The outer wall of the ring shovel 1 is provided with a foot pedal 4 for easy stepping and breaking the soil, so that the operator can use foot force to assist in breaking the soil, reduce hand pressure, and ensure that the operation process is easier and more efficient.

[0025] The handle 3 is inclined downwards at both ends, which allows the operator to maintain a natural arm posture during use and reduces discomfort during operation.

[0026] The handle 3 has ball-shaped ends 8 at both ends to increase the grip feel and prevent injury from the end face. The ball-shaped ends 8 at both ends of the handle 3 are designed to effectively prevent hand injuries caused by operator errors during use.

[0027] The end face of the locking groove 14 is provided with a rounded corner 15 to improve the engagement of the hook 11.

[0028] See Figure 3 Hold the handle 3 with both hands and step on the pedal 4 to insert the ring shovel 1 into the soil around the seedling. The soil-removing ring 6 slides upward under pressure until the wedge 13 hits and enters the hook 11. The locking groove 14 locks the hook 11, and the soil-removing ring 6 is fixed. At this time, the seedling can be moved to the location where it needs to be cultivated or transported. Then press the handle 9. The unlocking rod 10 is driven upward, causing the hook 11 to rotate counterclockwise. The hook 11 and the wedge 13 are disengaged. At this time, the spring pushes the sliding rod 7, which in turn pushes the soil-removing ring 6 downward, thereby pushing the seedling out of the ring shovel 1. Figure 1state.
