Description

Technical Field

[0001] The present invention relates to the field of seedling transportation, and more particularly to a seedling guide for a rice transplanter, a seedling transportation system for a wide-narrow row rice transplanter, and a wide-narrow row rice transplanter. Background Art

[0002] Currently, the wide-narrow row transplanting method has been widely used. It is a high-yield rice cultivation technique that uses alternating narrow and wide row spacing. The wide-narrow row rice cultivation model adjusts the overall layout of the rice field by changing the row and hole spacing, fully utilizing the light energy per unit area and promoting the formation of various yield factors, thereby achieving increased production and income. The wide-narrow row cultivation method not only ensures a reasonable number of holes per unit area, but also has advantages such as a reasonable plant population distribution and high photosynthesis rates. Therefore, it has a high yield level, can improve the rice population structure, enhance ventilation and light transmission conditions, and strengthen marginal effects, making it an important way to increase rice production. At the same time, the enhanced ventilation and light transmission reduces humidity between rice plants, which can reduce pest and disease damage to a certain extent, ultimately achieving the goal of high yield and increased income.

[0003] The wide-narrow row cultivation model improves the overall ventilation and light transmission in the field by adjusting the row spacing and hole spacing, enhances the marginal effect, increases the ambient temperature, reduces the ambient humidity, and significantly improves the field microclimate. Data show that the effective accumulated temperature during the rice growth period increased by 153.6°C. Calculated based on the average daily temperature of 21.3°C during the rice growth period, this is equivalent to an increase of 7.2 days in the growth period. The wide-narrow row cultivation model has a relatively reasonable arrangement of row spacing and hole spacing, which increases the photosynthetic radiation area and improves the light energy utilization rate per unit area. Data show that during the entire growth stage, the total effective photosynthetic radiation of wide-narrow row cultivation is 655W / m higher than that of large ridge single row cultivation. 2 , which is equivalent to an increase of about 23 days in the effective radiation time during the rice growth period.

[0004] Chinese patent application number: 201821237302.0, application date: August 2, 2018. The utility model is named: A wave seedling carrier for a rice transplanter. The application discloses a plate body, two seedling delivery belts and a cutter. The plate body is characterized in that the plate body is composed of a guide plate and a seedling delivery plate. The guide plate is arranged at the upper end of the seedling delivery plate, the cutter is longitudinally arranged in the middle of the seedling delivery plate, and two seedling delivery belts are arranged parallel to the seedling delivery plate. The middle of the seedling delivery belt has a longitudinal strip protrusion, which reduces the problem of tilting and offsetting of the blanket seedlings. However, the use of such a seedling carrier still cannot keep the seedlings relatively upright during the transplanting process and reduce the pulling between the roots of the seedlings. In addition, the design of the cutter makes the transplanter mechanism complex and bulky, with low reliability and increased danger during operation.

[0005] Chinese patent application number: 201510309019.9, filed on June 4, 2015, entitled "A Double-Blanket Narrow-Row Rice Transplanter and Its Operating Method." The application discloses a double-blanket narrow-row rice transplanter comprising a frame, a seedling platform, and a transplanting mechanism. The platform includes several seedling loading plates, including a central baffle that helps guide the movement of the blanket seedlings. However, this baffle is located at the top, while the lower portion remains interconnected. This makes it difficult to ensure the relative left and right position of the seedlings before transplanting, resulting in the seedlings not being properly removed by the transplanting claws. This reduces the reliability of seedling removal and affects the transplanting effect.

[0006] While current seedling delivery systems have solved the problems of seedling segmentation and partial guidance, they still struggle with positioning seedlings before transplanting. This can lead to left-right deviations and prevent them from being properly removed by the transplanting claws, reducing the reliability of seedling removal and affecting transplanting results. A more serious problem is that seedlings that are not fully removed by the transplanting claws can accumulate, preventing subsequent seedlings from being properly delivered, resulting in seedling shortages and interrupting normal transplanting operations.

[0007] The existing technology cannot well meet the requirements of improving the accuracy and success rate of transplanting seedlings, reducing the floating rate of seedlings, improving the uprightness of seedlings, facilitating early growth and rapid development of seedlings, and increasing the number of tillers.

At the same time, terms such as "upper", "lower", "left", "right", and "middle" quoted in this specification are only for the convenience of description and are not used to limit the scope of implementation. Changes or adjustments in their relative relationships should also be considered as the scope of implementation of the present invention without substantially changing the technical content.

[0050] The present invention will be further described below with reference to the embodiments.

[0051] Example 1

[0052] Combine Figure 1a A seedling guide for a rice transplanter in this embodiment includes a fixing portion 321, a seedling guiding portion 324 and a connecting portion 322, wherein the fixing portion 321 is fixedly connected to the seedling loading platform 1 when in use, for example, it can be fixed by bolt connection or welding.

[0053] The seedling guide 324 of this embodiment is located at the root of the seedlings 6 to be planted, and extends in a direction substantially parallel to the direction in which the seedlings are transported. The extended portion of the guide 324 can support the seedlings. During use, the seedlings on the seedling loading platform 1 gradually move downward, and the seedlings at the bottom of the seedling loading platform 1 are supported by the seedling guide 324. The seedling guide 324 can be used to guide the seedlings 6 to be planted correctly into the seedling gate.

[0054] As an embodiment, the fixing portion 321 and the seedling guiding portion 324 are connected by a connecting portion 322. The connecting portion 322 can be in the shape of a rod, such as a support rod or a bent rod, which can be connected to the middle or end of the seedling guiding portion 324, mainly playing a connecting role, without specific limitations.

[0055] The above-mentioned seedlings to be transplanted 6 refer to Figure 3 The seedlings shown in the figure are about to enter the seedling gate. The root of the seedling refers to the lower part of the seedling, specifically the part below 1 / 3. During transplanting, the upper part of the seedling is supported by the seedling bar 8. If the root is not supported, it will easily fall over. In this embodiment, by positioning the seedling guide 324 at the part below 1 / 3 of the seedling, the seedling can be supported from the middle and lower side, preventing the seedling from shifting during transplanting.

[0056] Example 2

[0057] Combine Figure 1a The basic structure of the seedling guide for a rice transplanter of this embodiment is the same as that of embodiment 1, with the following improvements:

[0058] The seedling guide of this embodiment also includes a curved portion 323. The seedling guide 324, the connecting portion 322, and the curved portion 323 form the extension 32. One end of the curved portion 323 is connected to the seedling guide 324, and the other end is connected to the connecting portion 322. The curved portion 323 is located at the end of the seedling guide 324 away from the transplanting claw 4. This curved portion 323 serves as a guide, allowing downward-moving seedlings to be separated along the curved portion 323 and supported by the seedling guide 324. This allows the seedlings 6 to enter the seedling gate correctly and be removed by the transplanting claw 4, improving the reliability of seedling removal and ensuring continuous transplanting.

[0059] Example 3

[0060] Combine Figure 1b The basic structure of the seedling guide for a rice transplanter of this embodiment is the same as that of embodiment 1, with the following improvements:

[0061] The seedling guide of this embodiment also includes a curved portion 323. The seedling guide portion 324, the connecting portion 322, and the curved portion 323 form the extension portion 32. The curved portion 323 is connected to the end of the seedling guide portion 324 away from the planting claw 4, and the connecting portion 322 is connected to the end of the seedling guide portion 324 closer to the planting claw 4. The curved portion 323 and the seedling guide portion 324 can guide the seedlings 6 to be planted correctly, allowing them to enter the seedling gate and be removed by the planting claw 4, improving the reliability of seedling removal and ensuring continuous planting.

[0062] Figure 1b The middle curved portion 323 extends in a manner that smoothly transitions with the seedling guide portion 324, and the other end is upwardly tilted. The curved portion 323 is preferably arc-shaped, convex away from the transplanting claw 4. The overall direction of the curvature of its structure is similar to the direction of seedling transportation, which can prevent the seedlings from being damaged when being transported downward and make the transportation process smoother.

[0063] Example 4

[0064] Combine Figure 1c The basic structure of the seedling guide for a rice transplanter of this embodiment is the same as that of embodiment 3, with the following improvements:

[0065] The bent portion 323 may be similar to Figure 1c In the structure shown, both ends of the curved portion extend toward the direction of the transplanting claw 4. This structure can not only relatively fix the roots, but also support the stems of the seedlings, resulting in a better effect.

[0066] The extension portion 32 may be rod-shaped or plate-shaped. When the extension portion 32 is rod-shaped, it is preferably a rod-shaped with a circular or elliptical cross-section. The above embodiment shows the specific structure when the extension portion 32 is rod-shaped.

[0067] Example 5

[0068] Combine Figure 1d The basic structure of the seedling guide for a rice transplanter of this embodiment is the same as that of embodiment 4, with the following improvements:

[0069] The extension portion 32 is plate-shaped, i.e., the seedling guide portion 324, the connecting portion 322, and the curved portion 323 are all integrated into a single plate. The seedling guide portion 324 and the connecting portion 322 correspond to the plate surface, and the curved portion 323 corresponds to the front edge of the plate. Preferably, the plate surface (or its extended surface) of the extension portion 32 is perpendicular to the plane of the seedling loading platform 1. The plate can be an integrally formed plate. Its main function is to provide a fixed support as a whole, which is conducive to driving the seedlings 6 to be planted correctly into the seedling gate.

[0070] Example 6

[0071] The seedling guide of a rice transplanter of this embodiment is based on the above embodiment, and the improvement of this embodiment is as follows:

[0072] It comprises two protruding parts 32 arranged in parallel, and a gap is left between the protruding parts 32, and the gap can fix the seedlings 6 to be planted in the middle position of the seedling loading platform 1.

[0073] Example 7

[0074] The basic structure of the seedling guide for a rice transplanter of this embodiment is the same as that of embodiment 6, with the following improvements:

[0075] The extension parts 32 are three extension parts 32 arranged in parallel, and there is a gap between the extension parts 32. The gap can fix the seedlings 6 to be planted in the middle position of the seedling loading platform 1. The seedling guiding part 324 is basically parallel, and the middle extension part 32 plays the role of supporting the seedlings. This arrangement can better guide the seedlings and guide the seedlings to enter the seedling gate correctly.

[0076] Example 8

[0077] Combine Figure 2 and Figure 3 The rice seedling conveying system of a wide and narrow row rice transplanter of this embodiment includes a rice seedling loading platform 1 for carrying a rice seedling tray. A conveyor belt is provided on the rice seedling loading platform 1. The rice seedling tray with a seedling blanket is placed on the conveyor belt and driven forward by the friction between the rice seedling tray and the conveyor belt to enter the gap between the rice seedling pressing rod 2 and the conveyor belt. The gap between the rice seedling pressing rod 2 and the conveyor belt is greater than the thickness of the rice seedling tray. The transverse guide rail 5 of the rice seedling loading platform 1 reciprocates, and a seedling guide 3 is provided in the middle of the rice seedling loading platform 1. The seedling guide 3 is connected to the rice seedling loading platform 1. The main function of the seedling guide 3 is to support the rice seedlings 6 to be transplanted, drive them to enter the rice seedling gate correctly, and ensure that the rice seedlings 6 to be transplanted are correctly removed by the transplanting claws 4. At the same time, the position and method of the seedling guide 3 will not interfere with the work of the transplanting claws 4.

[0078] As an embodiment, the distance between the extension part 32 and the seedling loading platform 1 can be adjusted according to the thickness of the seedling bed soil, preferably 2 to 5 cm, such as 2.3 cm, 3 cm, 4 cm, etc. If the distance between the extension part 32 and the seedling loading platform 1 is too high, it is difficult to achieve a fixing effect, and if it is too low, it is not conducive to transplanting and removing seedlings.

[0079] As an embodiment, the seedling guide 3 is detachably connected to the seedling loading platform 1, preferably by bolts. The detachable seedling guide 3 can be replaced according to the actual needs of different rice transplanter models and seedling conditions, and is also beneficial to the subsequent maintenance of the mechanical structure.

[0080] As an embodiment, a seedling blocking rod 8 is provided on the seedling loading platform 1. The seedling blocking rod 8 is arranged horizontally, and the lower part of the seedling blocking rod 8 and the lower end part of the seedling pressing rod 2 are fixedly connected, preferably welded. The seedling pressing rod 2 and the seedling blocking rod 8 jointly play the role of pressing the seedlings, and the seedling guide 3 is fixed on the seedling blocking rod 8. The seedling guide 3 and the seedling blocking rod 8 are fixed in a relatively non-movable connection manner, preferably a detachable connection, such as a bolt connection. On the one hand, the seedling guide 3 can be better fixed, and on the other hand, the seedling guide 3 can be selected according to the working conditions, and it is convenient for maintenance.

[0081] Preferably, a mounting portion 31 can be fixedly provided on the seedling blocking rod 8, the mounting portion 31 is welded to the seedling blocking rod 8, and the mounting portion 31 is a part of the seedling loading platform 1, and the fixing portion 321 of the seedling guide 3 is connected to the mounting portion 31, and the connection method is a relatively immovable method, preferably a detachable connection, which can be a bolt connection.

[0082] Example 9

[0083] Combine Figure 2 、 Figure 3 、 Figure 4a 、 Figure 4b and Figure 5 The basic structure of the rice seedling conveying system for a wide-narrow row rice transplanter of this embodiment is the same as that of embodiment 2, and its improvements are as follows:

[0084] A seedling guide bracket 7 is also provided in the middle of the seedling loading platform. The seedling guide bracket 7 is provided on the seedling loading platform 1. Its extension direction is substantially parallel to the seedling conveying direction. The seedling guide bracket 7 divides the seedling tray into two areas A and B ( Figure 2 ), the base soil layers in the two areas are separated, making it easy to separate the seedling blankets in the two areas; the seedling guide bracket 7 is used in conjunction with the seedling guide 3 to ensure that the seedlings in the two areas do not interfere with or tear each other when transplanting. During the working process, the upper seedling blanket gradually slides downward, and the seedling guide bracket 7 plays a limiting role to prevent the seedling blanket from moving left and right, and cooperates with the supporting role of the seedling guide 3 to ensure that the seedlings 6 to be transplanted enter the seedling gate correctly.

[0085] As an embodiment, the tail end of the seedling guide bracket 7 protrudes from the seedling loading platform 1 , and the tail end refers to the end of the seedling guide bracket 7 on the seedling loading platform 1 close to the seedling planting claw 4 .

[0086] As an embodiment, the seedling guide bracket 7 can be a plate of uniform thickness, and the thickness is controlled at 0 to 3 mm, for example, 0.5 mm, 1 mm, 2.5 mm, 3 mm, etc. Based on consideration of structural strength, it can be 1 to 3 mm.

[0087] As another embodiment, the cross section of the guide seedling support 7 can be a wedge-shaped plate structure, the thickness of the wedge plate gradually increases from top to bottom, and the cross section is a structure with a small top and a large bottom. Figure 4a 、 Figure 4b The top of the guide seedling bracket 7 is an arc-shaped sharp corner or a straight sharp corner, so that the thickness of the top is small, which is convenient for separating the seedling blankets in the two areas and ensuring that the seedling blanket is attached to the seedling loading platform 1.

[0088] Furthermore, the thickness of the seedling guide bracket 7 is not greater than 3 mm, and can be 1 to 3 mm based on considerations of structural strength and separation effect.

[0089] As an embodiment, the seedling guide bracket 7 is arc-shaped, and the height of the seedling guide bracket 7 is the largest near the bottom of the seedling loading platform 1, with a maximum height of 1 to 2 cm, preferably 1.5 cm. This structure is conducive to the seedling guide bracket 7 penetrating into the seedling blanket during the downward movement of the seedling blanket, ensuring that the seedling blanket is attached to the seedling loading platform 1.

[0090] It should be noted that the above-mentioned seedling loading platform mainly refers to a seedling supply unit corresponding to the two seedling claws, which can be specifically distinguished according to the contents of the attached drawings to facilitate the description of the specific setting structure. In a specific embodiment, a seedling conveying system can refer to the entire seedling loading rack, on which multiple seedling loading platforms are arranged, for example, 4 seedling loading platforms are arranged in parallel.
