[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0017] The following describes an embodiment of the present invention with a rice transplanter having a multi-seedling transplanting function, with reference to the accompanying drawings.

[0018] like Figures 1-4 As shown, the rice transplanter with multi-seedling transplanting function of this utility model embodiment may include: a base plate 1, a support frame 2, a power wheel 3, a transplanting mechanism 4, a seedling box 5, and a pull rod 6.

[0019] The base plate 1 has a through groove in the middle.

[0020] It should be noted that the base plate 1 described in this embodiment is used to make the equipment float on the mud surface in the paddy field. The front end of the base plate 1 is tilted upward to avoid resistance with the mud surface, thereby improving the mobility of the equipment.

[0021] The support frame 2 is installed on the upper part of the base plate 1, and the upper part of the support frame 2 is arranged at an angle.

[0022] It should be noted that the support frame 2 described in this embodiment is composed of multiple hollow steel pipes connected by bolts, and the upper steel pipes are arranged at an angle with the front higher than the back, which makes it lightweight and stable.

[0023] The drive wheel 3 is pivotally connected to the upper part of the support frame 2 via the first axle 301.

[0024] It should be noted that the first shaft 301 described in this embodiment is connected to the support frame 2 through a bearing seat, and the lower end of the power wheel 3 is located inside the through groove.

[0025] The rice transplanting mechanism 4 includes a swinging part 401, a transmission part 402, and two levers 403.

[0026] The swing part 401 is located on the upper part of the support frame 2, the transmission part 402 is located between the first shaft 301 and the swing part 401, and the two levers 403 are respectively located at both ends of the swing part 401.

[0027] It is understandable that as the base plate 1 moves forward, the resistance of the mud surface will drive the power wheel 3 to rotate. The power wheel 3 will then drive the swing part 401 to swing back and forth synchronously through the transmission part 402. The swing part 401 will then drive the two levers 403 to swing up and down back and forth.

[0028] The seedling box 5 is connected to the support frame 2 by two fixed rods 501, and the seedling box 5 is set at an angle.

[0029] Understandably, the seedling box 5 is used to hold two rows of rice seedlings in batches, which facilitates the planting of multiple seedlings and can realize the function of automatic material discharge.

[0030] The tie rod 6 is located at the upper front end of the support frame 2.

[0031] Specifically, during the rice planting season, small farmers with small planting areas or located in mountainous areas can use rice transplanters with multi-seedling transplanting functions to transplant rice seedlings in paddy fields.

[0032] Farmers first move the equipment into the paddy field, and then place two rows of seedlings horizontally into the seedling box 5 in batches, symmetrically, so that the roots of the seedlings face the corresponding lever 403 side.

[0033] Next, the farmer pulls the lever 6 with both hands to make the base plate 1 slide forward along the muddy surface of the paddy field. At this time, the power wheel 3 sinks into the mud and rotates under the action of resistance, which drives the first shaft 301 to rotate. The first shaft 301 drives the swing part 401 to swing back and forth synchronously through the transmission part 402. The swing part 401 will drive the two levers 403 to swing up and down back and forth. When the lever 403 moves in an arc into the seedling box 5, its end will get stuck at the root of the seedling. As the lever 403 descends, the seedling will gradually stand up and fall through the seedling box 5 until it is vertical and inserted into the mud with the lever 403. After the lever 403 reaches the lowest point, it will be pulled out of the mud and the next seedling will fall automatically in the seedling box 5 for repeated planting.

[0034] This allows farmers to quickly, evenly, and transplant multiple seedlings by pulling the equipment forward continuously.

[0035] In one embodiment of this utility model, such as Figure 1 As shown, the drive wheel 3 is provided with multiple resistance plates 302, and some of the resistance plates 302 can extend to the lower part of the bottom plate 1 through the through groove.

[0036] Specifically, when the equipment is located in the paddy field, the bottom plate 1 is in contact with the mud surface, and multiple resistance plates 302 at the bottom are inserted into the soil through the through groove. As the farmer pulls the equipment forward, the power wheel 3 will rotate.

[0037] In one embodiment of this utility model, such as Figure 3 As shown, the swing part 401 includes a second shaft 4011, a crank assembly 4012, a connecting rod 4013, and a rocker arm 4014.

[0038] The second shaft 4011 is pivotally connected to the upper rear end of the support frame 2. Two levers 403 are respectively installed at both ends of the second shaft 4011. The crank assembly 4012 is pivotally connected to the upper part of the support frame 2 and located between the second shaft 4011 and the drive wheel 3. The connecting rod 4013 is rotatably connected to the crank assembly 4012. The rocker arm 4014 is set on the second shaft 4011 and rotatably connected to the connecting rod 4013.

[0039] It should be noted that the crank assembly 4012 described in this embodiment consists of two discs connected to the support frame 2 via bearing seats. The two discs are connected by a positioning rod, and the connecting rod 4013 is rotatably connected to the positioning rod. When the crank assembly 4012 rotates at a constant speed, it drives the connecting rod 4013 to perform a planar compound motion. The connecting rod 4013 drives the rocker arm 4014 and the second shaft 4011 to perform a variable-speed reciprocating swing. Thus, the second shaft 4011 can drive the two levers 403 to swing up and down reciprocally. When the end of the lever 403 descends to the lowest point, it will insert into the soil below the base plate 1.

[0040] In one embodiment of this utility model, such as Figure 3 As shown, the transmission unit 402 includes a first synchronous pulley 4021, a second synchronous pulley 4022, and a synchronous belt 4023.

[0041] The first synchronous pulley 4021 is mounted on the first shaft 301, the second synchronous pulley 4022 is mounted on the crank assembly 4012, and the synchronous belt 4023 is sleeved between the first synchronous pulley 4021 and the second synchronous pulley 4022.

[0042] Specifically, the second synchronous wheel 4022 is mounted on one of the discs of the crank assembly 4012. When the equipment moves in the paddy field, the power wheel 3 rotates and drives the first synchronous wheel 4021 to rotate through the first shaft 301. The first synchronous wheel 4021, in conjunction with the synchronous belt 4023, drives the second synchronous wheel 4022 to rotate. The second synchronous wheel 4022 then drives the crank assembly 4012 to rotate, thereby driving the lever 403 to swing back and forth, realizing the function of continuous and equally spaced rice planting.

[0043] In one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, a partition 502 is provided in the middle of the seedling box 5, and discharge ports 503 are provided on both sides of the bottom of the seedling box 5. Baffles 504 are provided at the bottom of the seedling box 5 near the two discharge ports 503.

[0044] The lever 403 has a slot at one end and is arranged in a curved manner. The lever 403 is adapted to the corresponding discharge port 503.

[0045] It is understandable that the end of the lever 403 can pass through the discharge port 503 during the up-and-down swinging process, and the thickness of the lever 403 is less than the width of the discharge port 503, so that the gap between the lever 403 and the discharge port 503 can accommodate a seedling.

[0046] It should be noted that the seedling box 5 described in this embodiment also has two openings at the lower front side to facilitate the entry of the lever 403. The lower rear wall of the seedling box 5 is provided with a slope. The partition 502 divides the seedling box 5 into two equal spaces, which can hold two rows of seedlings at the same time.

[0047] Specifically, during rice transplanting, farmers place two groups of seedlings horizontally into the seedling box 5, with the roots of the seedlings facing the corresponding discharge port 503. Since the seedling box 5 is arranged at an angle, the seedlings slide down the inner wall after being placed in the box, and then slide down the slope to the bottom of the seedling box 5. At this time, the bottom seedling is misaligned with the other seedlings. When the lever 403 falls, the groove at its end will catch the root of the seedling. As the lever 403 descends, the seedling will gradually stand up and fall through the discharge port 503. During the falling process, the seedling remains vertical under the limiting action of the baffle 504 and the lever 403. Then, the lever 403 drives the root of the seedling to insert into the soil. Finally, the lever 403 is retracted and rises to continue transplanting the seedlings that automatically fall in the seedling box 5, which improves the transplanting efficiency while ensuring the transplanting quality.

[0048] In summary, the rice transplanter with multi-seedling transplanting function of this utility model has a simple structure, is easy to use, does not require the use of motors or batteries, has low production and maintenance costs, improves the efficiency and quality of rice transplanting while reducing the intensity of manual labor, reducing farmers' input, and increasing the income of cultivation.
