Description

Technical Field

[0001] This utility model relates to the technical field of vegetable transplanting equipment, and in particular to a transplanting mechanism that utilizes slide rail movement. Background Technology

[0002] With global population growth and accelerated urbanization, the demand for vegetables is constantly increasing. Traditional manual transplanting methods are inefficient and labor-intensive, making it difficult to meet the needs of large-scale planting. Vegetable transplanting machines have emerged to address this need. They can achieve efficient and precise transplanting operations, significantly improving production efficiency, reducing labor costs, and ensuring the quality of vegetable transplanting. They have become an important trend in modern agricultural development.

[0003] However, during the transplanting of vegetables in dryland areas, the speed difference between the transplanter and the soil when the transplanter enters the soil can easily disturb the soil, causing the seedling hole to loosen or collapse, which in turn causes the vegetables to lean or fall over, affecting the transplanting quality and survival rate. This problem has received widespread attention in research and application both domestically and internationally. Although some studies have made progress by optimizing the design of the transplanter, adjusting the transplanting speed, and adopting vibration compaction technology, further exploration of more effective solutions is still needed under complex dryland conditions to improve the performance and adaptability of vegetable transplanters and meet the demands of modern agriculture for efficient and precise transplanting.

The other end of the cam push rod is connected to the closing gate line and the opening gate line, respectively. The function of this switch transmission structure is that when the cam protrusion contacts the bearing, the opening gate line is in a tightened state; the concave part of the cam allows the cam push rod to pull the closing gate line to close the planting duckbill device, thus realizing the periodic opening and closing of the planting duckbill device.

[0014] Preferably, the lever lifting structure includes a brake line fixing plate, a duckbill opening and closing slide rail, and a duckbill opening and closing slider.

[0015] This utility model has the following advantages and beneficial effects compared to the prior art:

[0016] 1. The present invention provides a transplanting mechanism using a sliding rail motion, which is equipped with eight planting duckbill devices, resulting in higher work efficiency and higher economic benefits. At the same time, the planting duckbill devices move vertically downward relative to the machine before entering the soil, thus improving the stability of the seedlings.

[0017] 2. The planting duckbill device of this utility model, which utilizes a sliding rail motion transplanting mechanism, is installed on the vertical moving structure of the duckbill device. After the planting duckbill device is inserted into the soil, there is no power input in the horizontal direction. The planting duckbill device can move freely on the transverse sliding rail, but the resistance of the soil will limit the movement of the planting duckbill device. This is equivalent to compensating for the horizontal movement of the planting duckbill device, thereby reducing the disturbance of the soil by the planting duckbill device and improving the transplanting quality. At the same time, an extension rod is also installed in front of the planting duckbill device to increase the contact area with the soil and increase the stability of the duckbill device when it is inserted into the soil.

[0038] Description of the working process of a transplanting mechanism utilizing slide rail motion:

[0039] Step 1: The drive motor 201 drives the drive shaft 204 to rotate via the coupling 203, which in turn drives the turntable 316 to rotate. The turntable 316 pushes the transverse slide rail 313 to slide downward along the longitudinal guide rail 312 via the rocker arm 315. The transverse slide rail 313 drives the duckbill opening and closing unit 1 to move downward as a whole. At this time, during the process of the transverse slide rail 313 moving from the upper end to the lower end of the longitudinal guide rail 312, the duckbill opening and closing transmission unit 4 is in the initial position, and the duckbill planter 125 remains in the closed state. The magnet 331 on the transverse sliding bracket 314 is attracted to the magnet 331 on the transverse slide rail 313, keeping the duckbill planter 125 at the front end of the mechanism.

[0040] Step 2: The drive motor 201 sequentially drives the shaft 204, turntable 316, and rocker arm 315 to continuously drive the horizontal slide rail 313 downward until the duckbill opening and closing structure 12 is inserted into the soil. The extension rod 113 keeps the duckbill planting device in a stable position in the soil. The soil resistance causes the duckbill opening and closing structure 12 to move horizontally backward (that is, the horizontal sliding bracket 314 moves from the front end to the rear end of the horizontal slide rail 313). The magnet 331 on the horizontal sliding bracket 314 and the magnet on the horizontal slide rail 313 are subjected to tension, which causes the horizontal sliding bracket 314 and the horizontal slide rail 313 to separate back and forth.

[0041] Step 3: The drive motor 201 continues to drive the drive shaft 204 to rotate, the turntable 316 pulls the rocker arm 315 to move upward, and the rocker arm 315 drives the transverse slide rail 313 to move upward; at the same time, the cam 411, through the bearing 412 and the cam push rod 413, pulls the opening gate cable 44 to drive the duckbill opening and closing slider 423 to move to the lower end of the duckbill opening and closing slide rail 422. The duckbill opening and closing slider 423 drives the transmission rod 112 to move downward. The transmission rod 112 pushes the planting duckbill device 125 to open through the first straight rod 121, the second straight rod 122, the first curved rod 123 and the second curved rod 124, so that the seedling falls into the soil. Under the push of the cam 411, the planting duckbill device 125 remains open during the process of exiting the soil.

[0042] Step 4: When the planting duckbill device 125 is completely detached from the soil and is being lifted by the transverse slide rail 313, the transverse slide rail 313 pulls the lever 322 around the pivot 323 via the second return cable 324. The lever 322 pulls the transverse sliding bracket 314 from the rear end to the front end of the transverse slide rail 313 via the first return cable 321. Under the attraction of the two magnet blocks 331, the duckbill device opening and closing unit 1 remains at the front end of this transplanting mechanism. When the transverse slide rail 313 moves to the uppermost end of the longitudinal guide rail 312, there is no thrust from the cam 411 on the bearing 412. Under the action of gravity, the cam push rod 413 moves vertically downward. The cam push rod 413 pulls the closing gate line 43 to drive the duckbill opening and closing slider 423 to move to the upper end of the duckbill opening and closing slide rail 422. The duckbill opening and closing slider 423 drives the two transmission rods 112 to move upward, thereby closing the duckbill planting duckbill 125 of the duckbill opening and closing structure 12.

[0043] The above-described specific embodiments are preferred embodiments of this utility model and are not intended to limit this utility model. Any other changes or equivalent substitutions made without departing from the technical solution of this utility model are included within the protection scope of this utility model.
