Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a rice transplanter's seedling boat structure. Background Technology

[0002] As a key piece of equipment in the rice planting process, the structure of the rice transplanter's seedling pod significantly impacts the quality and efficiency of the transplanting operation. Currently, most rice transplanter seedling pods on the market adopt a rigid, integrated structure, which presents numerous problems in actual operation.

[0003] The existing patent publication number CN221829452U discloses a rice transplanter boat structure, including a boat body, with connecting blocks fixedly and symmetrically connected to the top of the boat body. The wall surface of the boat body is provided with a leveling structure, which includes leveling teeth and pressure rollers. The leveling teeth are fixedly connected to the bottom of the boat body, and the pressure rollers are rotatably connected to the rear wall surface of the boat body. The leveling structure can level the field. By setting the leveling structure, the mud surface passed by the rice transplanter can be filtered and flattened.

[0004] However, in the embodiments described in the aforementioned patent, the bottom of the rice transplanter is a flat structure and no mud discharge channel is provided. When the rice transplanter is moving, the silt in the paddy field is easy to accumulate at the bottom of the rice transplanter. As the working time increases, the thickness of the accumulated mud gradually increases, which not only increases the driving resistance, but also causes the overall height of the rice transplanter to rise, which destroys the stability of the transplanting depth. In addition, it cannot adaptively adjust the contact state with the field surface according to the flatness of the paddy field (such as the presence of small bumps and depressions). When working on uneven fields, the rice transplanter is prone to partial suspension or excessive compression of the field surface, which causes the rice transplanter to tilt and affects the verticality and spacing accuracy of the seedlings. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] To address the problems mentioned above, such as excessive silt accumulation at the bottom of the hull during movement, which increases movement resistance and prevents the hull from adaptively adjusting its height according to the paddy field height, leading to easy tilting of the hull, this utility model is proposed.

[0008] Therefore, the purpose of this utility model is to provide a rice transplanter's seedling boat structure that can automatically divert silt, reduce accumulation, and adaptively adjust its height to maintain stable movement.

[0009] 2. Technical Solution:

[0010] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0011] A rice transplanter's seedling boat structure includes a hull, with a plurality of diversion components arranged in an array at the bottom of the hull for diverting silt, and the diversion components are V-shaped.

[0012] The bottom of the hull has a movable groove with the same shape as the diverter, and the top of the hull has several through slots that are connected to both ends of the movable groove. The top of both ends of the diverter is fixedly provided with a limiting rod passing through the through slot, and the top side of the hull is fixedly installed with a reset component for limiting the limiting rod.

[0013] As a preferred embodiment of the rice transplanter boat structure of the present invention, the diverter has a first guide slope inclined at 45° on one side facing the front of the hull, and the other side of the diverter has a second guide slope with the same inclination angle as the first guide slope on the V-shaped surface.

[0014] As a preferred embodiment of the rice transplanter boat structure of the present invention, a ball bearing is embedded in the top of the limiting rod, and a limiting ring that fits against the top surface of the boat is fixedly installed on the outer wall of the limiting rod by threads.

[0015] As a preferred embodiment of the rice transplanter boat structure of the present invention, the reset component includes a fixed shell, a pressure plate that fits against the top of the limiting ring is movably installed between the inner walls of the fixed shell, and a spring is fixedly connected between the pressure plate and the facing surface of the top of the fixed shell.

[0016] As a preferred embodiment of the rice transplanter boat structure of the present invention, an adjusting plate is threadedly connected to the top center of the fixed shell, and an adjusting threaded block that fits against the inner wall of the fixed shell is installed at the end of the adjusting plate inside the fixed shell, and the adjusting threaded block is fixedly connected to a spring.

[0017] As a preferred embodiment of the rice transplanter boat structure of the present invention, the top side of the boat is provided with a plurality of diversion channels communicating with through slots at different positions, and the end of the diversion channel is provided with a drainage channel penetrating the side of the boat.

[0018] As a preferred embodiment of the rice transplanter boat structure of the present invention, the bottom side of the diversion trough is constructed with a first downward slope, and the bottom side of the drainage trough is constructed with a second downward slope.

[0019] 3. Beneficial effects:

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. The rice transplanter's boat structure, with its V-shaped diverter array at the bottom, precisely diverts the silt beneath the boat to both sides during transplanting. Compared to traditional smooth bottoms, this significantly reduces silt adhesion and resistance. The V-shaped structure guides the silt smoothly along the inclined surface of the diverter, preventing silt accumulation and obstruction at the bottom. This makes the transplanter move more smoothly in muddy fields, effectively reducing power consumption, minimizing the probability of the boat sinking, and improving overall machine efficiency.

[0022] 2. The seedling boat structure of this rice transplanter features a ball bearing embedded in the top of the limiting rod. This ball bearing converts the sliding friction between the limiting rod and the reset plate into rolling friction, significantly reducing frictional resistance. This allows the diverting component to move more sensitively and smoothly along the movable groove under the pressure of silt, preventing adjustment lag caused by friction jamming. Simultaneously, the limiting ring, fixed to the outer wall of the limiting rod by threads, fits tightly against the top surface of the boat, precisely limiting the lowest extension position of the diverting component and preventing it from excessively descending and scratching the field bottom. Combined with the elastic force of the spring in the reset component, this ensures rapid response and stable reset of the diverting component in areas with varying silt thicknesses. Even in complex field conditions with alternating depths, it maintains optimal diversion, further enhancing the equipment's versatility.

[0023] 3. The rice transplanter's boat structure features V-shaped diverter components arrayed at the bottom of the boat, which are movably connected to the boat body via movable grooves. Limiting rods at both ends pass through these grooves and are installed in conjunction with reset components. When small protrusions exist in the paddy field, the protruding parts push upwards towards the corresponding diverter components, causing them to move upwards along the movable grooves. Simultaneously, the limiting rods slide within the grooves, preventing the diverter components from being partially suspended due to obstruction by the protrusions. When encountering a concave area, the elastic force of the reset components presses the diverter components downwards through the limiting rods, ensuring the diverter components remain in contact with the concave surface. This prevents the diverter components from detaching from the field surface or the boat body from excessively compressing the surrounding area due to concavity. This dynamic adjustment structure, allowing the boat to move upwards when protruding and downwards when concave, enables the rice transplanter to adapt to changes in field flatness in real time, ensuring stable contact between the boat body and the field surface and fundamentally preventing machine tilting.

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] This utility model provides a rice transplanter boat structure that can divert silt from the bottom of the boat through a diversion component, reducing the accumulation and increasing the resistance to movement. It can also be adaptively adjusted according to the unevenness of the field surface to maintain stable movement.

[0033] Figures 1-5 The diagram shown is a structural schematic of one embodiment of the seedling boat structure of a rice transplanter according to this utility model. Please refer to [link / reference]. Figures 1-5 The present invention relates to a rice transplanter boat structure, the main body of which includes a boat hull 1 and a diverter 2;

[0034] The bottom of the hull 1 is arranged with several diversion components 2 for diverting silt, and the shape of the diversion components 2 is V-shaped.

[0035] The bottom of the hull 1 is provided with a movable groove 101 with the same shape as the diverter 2. The movable groove 101 is provided for the diverter 2 to move upward and adjust its height so as to adapt to different height positions in the paddy field and maintain the stability of the movement of the hull 1. The top of the hull 1 is provided with several through grooves 102 that are connected to both ends of the movable groove 101. The top of both ends of the diverter 2 are welded and fixed with limiting rods 3 that pass through the through grooves 102. The through grooves 102 are long and strip-shaped, which can reserve movement space for the limiting rods 3 when the diverter 2 tilts and deviates. The top side of the hull 1 is fixed with a reset piece 4 for limiting the position of the limiting rods 3 by bolts.

[0036] Furthermore, in order to improve the diversion effect and limit the vertical displacement angle, specifically, the diversion component 2 has a first guide slope 201 with an inclination of 45° on one side facing the front of the hull 1, and the other side of the diversion component 2 has a second guide slope 202 with the same inclination angle as the first guide slope 201 on the V-shaped surface. This can further improve the diversion effect, reduce silt accumulation, and keep the diversion component 2 tilted. In addition, the inclined inner wall of the movable groove 101 near the bottom is embedded with a sealing strip 105, which can improve the sealing performance in contact with the diversion component 2, and at the same time improve the silt cleaning effect when the diversion component 2 tilts upward.

[0037] Meanwhile, in order to reduce frictional resistance and limit the lowest position of the diverter 2, specifically, a ball bearing 301 is embedded in the top of the limiting rod 3, and a limiting ring 302 that fits against the top surface of the hull 1 is fixedly installed on the outer wall of the limiting rod 3 by threads. The ball bearing 301 contacts the reset component 4 and can reduce resistance through frictional rotation. The limiting ring 302 is connected by threads, which facilitates disassembly and assembly operations. The lowest position of the diverter 2 can be adjusted according to the needs of use.

[0038] It is worth noting that, in order to improve the automatic reset effect of the diverter 2, the reset component 4 specifically includes a fixed shell 401. A pressure plate 402 that fits against the top of the limiting ring 302 is movably installed between the inner walls of the fixed shell 401. A spring 403 is fixedly connected between the pressure plate 402 and the top facing surfaces of the fixed shell 401. With the support of the spring 403, an elastic force can be formed after the limiting rod 3 is squeezed and contracted, so that the diverter 2 can be quickly reset by the force of the spring 403 without pressure.

[0039] Next, in order to adjust the displacement resistance of the diverter 2, specifically, an adjusting plate 404 is threadedly connected to the top center of the fixed shell 401. The end of the adjusting plate 404 located inside the fixed shell 401 is in contact with an adjusting threaded block 405 that fits against the inner wall of the fixed shell 401. The adjusting threaded block 405 is fixedly connected to the spring 403. The threaded adjusting plate 404 can adjust the position of the adjusting threaded block 405, thereby adjusting the extension and contraction strength of the spring 403.

[0040] Next, in order to drain the water seeping from the slot 102, several drainage channels 103 connected to the slots 102 at different locations are provided on the top side of the hull 1. The end of the drainage channel 103 is provided with a drainage channel 104 that penetrates the side of the hull 1, so that the water seeping from the slot 102 can be discharged from the drainage channel 103 and the drainage channel 104.

[0041] Finally, in order to improve drainage, specifically, the bottom side of the diversion channel 103 is constructed with a first downward slope 106, and the bottom side of the drainage channel 104 is constructed with a second downward slope 107.

[0042] Combination Figures 1-5 The specific implementation method of the seedling boat structure of this rice transplanter is as follows:

[0043] 1. First, as the rice seedling boat moves forward, the V-shaped diverter 2 at the bottom of the hull 1 comes into contact with the silt in the field. The first guide slope 201 facing the front of the hull 1 and the second guide slope 202 on the other side (both inclined at 45°) work together to efficiently divert the silt in front of the hull 1 to both sides, reducing the resistance of the silt to the forward movement of the hull 1 and preventing the silt from accumulating at the bottom of the hull 1 and affecting the stability of the rice seedling boat.

[0044] 2. If the thickness of the silt in the field is uneven or if it encounters hard impurities such as small clods of soil, the diverting component 2 will experience varying degrees of resistance. When the resistance is greater than the initial preload of the resetting component 4, the diverting component 2 will move upward along the movable groove 101, causing the limiting rod 3 to move upward synchronously within the through groove 102. At this time, the ball bearing 301 at the top of the limiting rod 3 rolls into contact with the inner wall of the through groove 102, reducing frictional resistance and ensuring smooth movement of the limiting rod 3; simultaneously, the limiting ring 302 on the limiting rod 3 presses upward against the pressure plate 402 of the resetting component 4, causing the spring 403 to be further compressed and store elastic potential energy. If the silt resistance decreases subsequently, the spring 403 releases its elastic potential energy, pushing the pressure plate 402, the limiting ring 302, and the limiting rod 3 downward, causing the diverting component 2 to reset, thus maintaining effective contact with the silt and the diversion effect.

[0045] 3. During operation, some water from the silt or accumulated water from the field will enter the drainage channel 103 on top of the hull 1 through the channel 102. Under the action of gravity, the water entering the drainage channel 103 flows rapidly down the first downward slope 106 to the drainage channel 104, and then down the second downward slope 107 inside the drainage channel 104, and is discharged from the outlet of the drainage channel 104 on the side of the hull 1. This prevents water from accumulating on the top of the hull 1, prevents water from seeping into the internal structure of the seedling boat and affecting the life of the components, and at the same time reduces the extra weight of the hull 1 and ensures the stability of the operation.
