Description

Technical Field

[0001] The utility model relates to agricultural machinery and equipment, in particular to a device for planting seedlings. Background Art

[0002] When planting some economic crops, it is necessary to raise seedlings in advance and then transplant the seedlings into the soil. In large-scale and standardized planting, agricultural machinery equipment is generally used instead of manual transplanting. The key device for planting seedlings into the soil is to use a duckbill seedling planting device, such as the duckbill soil entry mechanism of sugarcane seedlings disclosed in the Chinese utility model patent with publication number CN218104138U, which includes a pair of duckbill structures, and the seedlings are placed in the inner cavity of the duckbill. The duckbill is inserted into the soil and opened to allow the seedlings to fall into the soil to complete the transplanting. The traditional seedling planting device is basically similar to the above-mentioned disclosed structure. In order to keep the seedlings upright after planting, the inner cavity size should not be too large, resulting in the size of the large diameter part of the cone of the duckbill structure being limited. The traditional size is basically around 60 mm, so that the seedlings can remain upright in the inner cavity, and the seedlings can remain upright and not fall over after transplanting. In some seedling transplanting processes, the seedlings need to be transplanted into pits to protect them from wind and cold and to facilitate water storage. The traditional method is to add a drill-type nest-making device to the equipment to make nests in advance, and then use the device disclosed in the above patent to transplant the seedlings into the pits. Utility Model Content

[0003] In order to provide a seedling planting device that does not require pre-nesting and can form a pit in the soil through a duckbill structure during the transplanting process, the technical solution adopted by the utility model is:

[0004] A seedling planting device, comprising:

[0005] It has a pair of duck bills that can move around their respective hinges;

[0006] An opening mechanism for driving the pair of duckbills to open synchronously;

[0007] a closing mechanism for driving and maintaining the pair of duckbills closed;

[0008] The pair of duck bills are cone-shaped in the closed state and open and close at the center of the cone;

[0009] The size of the cones in the closed state of the duckbill gradually increases from the small diameter end to the large diameter end between the outer wall and the inner wall of the inner cavity.

[0010] Furthermore, the pair of duckbills, in a closed state, comprises an inner cylinder whose inner cavity is substantially cylindrical and an outer cylinder whose outer wall is conical.

[0011] Furthermore, the end of the inner cylinder extends out of the small-diameter end of the outer cylinder.

[0012] Furthermore, it also includes a limiting mechanism for limiting the opening angle of the pair of duckbill.

[0013] Furthermore, it also includes a bracket and a pair of mounting frames, wherein the pair of mounting frames are respectively hinged on the bracket, the duckbill is respectively fixed on the mounting frames, and the opening mechanism and the closing mechanism are arranged between the pair of mounting frames.

[0014] Furthermore, a seedling throwing bucket is also arranged on the support.

[0015] Furthermore, the outer diameter of the large diameter end of the cone in the closed state of the duckbill is greater than 100 mm.

[0016] Furthermore, the opening mechanism is a brake wire.

[0017] Furthermore, the closing mechanism is a tension spring.

[0018] By adopting the above technical solution, since the size of the inner cavity will not change as the size of the outer wall increases, the size of the outer wall can be made large enough to ensure that the seedlings remain in a vertical state in the inner cavity. The sufficient outer wall size can form a pit when inserted into the soil, and then the seedlings can be directly transplanted into the pit formed by the device through the device during transplanting.

[0020] Figure 2 This is a schematic diagram of the structure of the seedling planting device in the open state;

[0021] Figure 3 This is a state diagram of planting seedlings using the seedling planting device. DETAILED DESCRIPTION

[0022] In order to better understand the utility model concept of the utility model, the following structural drawings and specific embodiments further illustrate the utility model in detail.

[0023] like Figure 1 and Figure 2 The seedling planting device shown includes a bracket 5, which serves as a planting body for connecting the device with a transplanting device so that the device can be installed in a transplanting machine. Therefore, the bracket 5 can also be regarded as a part of the transplanting device.

[0024] In this embodiment, the bracket 5 is used as a component of the device. A pair of mounting frames 6 are hingedly arranged on the bracket 5. The mounting frames 6 can move independently around their respective hinge points. In this embodiment, the opening mechanism 2 that drives the mounting frames 6 to move around their hinge points is a brake wire, wherein the outer layer and inner core of the brake wire are respectively connected to the two mounting frames 6. When the inner core of the brake wire is pulled, the two mounting frames 6 rotate around the hinge. A tension spring as a closing mechanism 3 is also arranged on the mounting frame 6. When the opening mechanism 2 is released, the tension spring pulls the two mounting frames 6 together. In order to make the opening angle of the mounting frame 6 within a reasonable range, a limiting mechanism 4 is arranged on the mounting frame 6. Specifically, as shown in the figure, an arc groove is arranged on one of the mounting frames 6, and a pin is arranged on the other mounting frame 6. The pin is placed in the arc groove. When the mounting frame 6 is opened, the pin can move along the arc groove. The arc groove limits the movement range of the pin, thereby achieving the limit of the opening angle of the mounting frame 6.

[0025] In order to realize the transplanting of seedlings and form pits in the soil during the transplanting process, the key structural parts of the device are arranged on the mounting frame 6, that is, a duckbill 1 is arranged on each mounting frame 6, and the opening and closing of the mounting frame 6 drives the pair of duckbill 1 to open and close. Figure 1 As shown, the pair of duck bills 1 are combined into a cone in the closed state, with one end with a large diameter connected to the mounting frame 6 and the other end with a small diameter as a free end with a maximum opening angle. The cone after the pair of duck bills 1 are combined has an inner cavity and an outer wall, wherein the inner cavity is used to place seedlings, and the outer wall is in direct contact with the soil when inserted into the soil. Since the position of the seedlings is completely restricted by the inner cavity, the seedlings can remain upright if the inner cavity space is reasonable, and then after the duck bill 1 is inserted into the soil and opened, the seedlings can be transplanted into the soil upright. If the inner cavity space is larger, such as when the traditional inner cavity shape is consistent with the outer contour of the duck bill, if the duck bill is larger in size or has a larger taper, the seedlings placed in the inner cavity will fall over, and will also fall over after being transplanted into the soil. In order to form a pit in the soil, the outer contour size of the duck bill 1 needs to be increased, so the use of the traditional duck bill structure will form a contradiction, that is, the inner cavity size and the outer wall size cannot be satisfied at the same time. In order to keep the seedlings upright, the duckbill 1 can also form a pit when inserted into the soil, so that the inner wall size of the cone inner cavity of the pair of duckbills 1 in the combined state remains basically unchanged from the small diameter end to the large diameter end, while the size of the outer wall gradually increases from the small diameter end to the large diameter end. Since the inner wall size of the inner cavity no longer changes with the size of the outer wall, the size of the outer wall can be large enough to form a pit in the soil when the duckbill is inserted into the soil and then pulled out.

[0026] In order to achieve the inconsistency between the inner wall size and the outer wall size of the duckbill, such as Figure 2The technical means adopted in the embodiment shown is to set an inner cylinder 1-1 as a component of the inner cavity to make it cylindrical so that the size of its inner cavity is consistent, and an outer cylinder 1-2 is set outside the inner cylinder 1-1 to form a cone, and the size of its large diameter end is designed to a reasonable size range according to needs, such as: the large diameter of the cone after the traditional duckbill combination is generally about 60mm, and in order to form a pit nest, the large diameter part of the outer wall in this structure is set to be greater than 100mm to meet the requirements of making a nest, while the inner cavity size of the inner cylinder 1-1 is still maintained at about 60mm to meet the seedlings in the inner cavity. Of course, the means given in this embodiment are more preferred, and of course, the inner cavity size and the outer wall size can also be made larger by increasing the wall thickness, but relatively speaking, the material consumption will increase, and the corresponding cost will also increase.

[0027] In order to facilitate the throwing of seedlings into the inner tube 1-1, a funnel-shaped seedling throwing bucket 7 is also provided on the bracket 5. After the seedlings are thrown into the seedling throwing bucket 7, the seedlings will fall into the inner cavity of the duckbill 1 and wait for the duckbill to be inserted into the soil for transplanting.

[0028] When transplanting, Figure 3 As shown, first keep the two duck bills 1 closed to form a cone, insert them into the soil, push the soil to the surrounding through the action of the outer wall, and after inserting to a sufficient depth, the opening mechanism 2 drives the two duck bills 1 to open, and the seedlings fall. Then the device is extracted from the soil. During the extraction process, the soil at the bottom of the pit buries the bottom of the seedlings under the action of gravity to complete the transplanting of the seedlings. At this time, the seedlings are in the pit, which can not only protect against wind and cold, but also facilitate water storage during irrigation.

[0029] Since the burial of the seedlings is still achieved by the falling back of the soil, if the cone size of the duckbill is too large, a pit will be formed and the soil will not be able to bury the roots of the seedlings smoothly. Therefore, it is preferred to keep one end of the small diameter consistent in size and higher than the small diameter end of the cone. For example, in the embodiment, the free end of the inner cylinder is longer than the free end of the outer cylinder. In this way, the inner cylinder forms a smaller pit in the pit, which is convenient for the soil to automatically backfill and bury the seedlings.
