Description

Technical Field

[0001] The present invention belongs to the field of agricultural machinery, and specifically relates to a seedling fixing device for a transplanter that prevents lateral deviation of seedlings. Background Art

[0002] Wide-narrow row transplanting is a high-yield rice cultivation technique. By adjusting the row spacing of the transplanter, interval cultivation of narrow row spacing and wide row spacing is achieved, which is beneficial to improving the photosynthesis rate, enhancing ventilation and light transmission, and reducing pests and diseases.

[0003] However, when using this cultivation technique, since two seedling claws simultaneously pick up a tray of seedlings, when the two seedling claws move to the middle position of the planting table to pick up seedlings, there is seedling swaying, and the seedling claws cannot pick up the seedlings, resulting in a high probability of seedling clogging and no seedling dropping. Summary of the Invention

[0004] Object of the Invention: A technical solution for designing a seedling fixing device on a transplanter is provided. The seedling fixing device can assist in the stability of seedlings, prevent the seedlings at the middle position of the planting table from swaying left and right during transplanting, thereby improving the transplanting performance and reducing the probability of seedling clogging and no seedling dropping.

[0005] The technical solution of the present invention is as follows: A seedling fixing device for a transplanter that prevents lateral deviation of seedlings includes: a fixing part and a seedling guiding part.

[0006] The fixing part is installed on the back of the planting table, and the seedling guiding part is arranged at the middle position of the planting table.

[0007] The seedling guiding part is connected to the fixing part, and the seedling guiding part extends along the seedling conveying direction.

[0008] In a further embodiment, the fixing part and the seedling guiding part are fixedly connected.

[0009] In a further embodiment, the fixing part and the seedling guiding part are detachably connected.

[0010] In a further embodiment, a sliding plate is provided on the back of the planting table, and the fixing part is installed on the sliding plate, which can improve the structural strength of the installation of the seedling fixing device without damaging the structural strength of the front of the planting table.

[0011] In a further embodiment, the seedling fixing device for the transplanter further includes bolts and nuts. The bolts pass through the sliding plate and the fixing part, and the bolts and nuts are screwed together to install the fixing part on the sliding plate.

[0012] In a further embodiment, a sliding member is provided on the back of the sliding plate.

[0013] The nut is arranged on the side of the sliding plate away from the sliding component, so that the nut is arranged outside the sliding plate. When the bolt is loosened and the seedling fixing device is removed, it is easy to access the bolt nut, which facilitates disassembly and assembly and can reduce the dropping rate of the nut during disassembly.

[0014] In a further embodiment, the height of the head of the bolt is higher than the upper end position of the sliding component, which can reduce the risk of interference between the head of the bolt and the sliding component.

[0015] In a further embodiment, one end of the fixing portion close to the sliding plate extends along the length direction of the sliding plate.

[0016] The fixing portion or the sliding plate is provided with a long hole, which extends along the length direction of the sliding plate. The bolt passes through the long hole, so that the position of the fixing portion along the length direction of the sliding plate can be finely adjusted.

[0017] In a further embodiment, the fixing portion is arranged on the side of the sliding plate close to the conveyor belt, so that the seedling guiding portion extends from one side of the conveyor belt along the seedling conveying direction.

[0018] The beneficial effects of the present invention are as follows: By arranging the seedling guiding portion at the middle position of the rice transplanting table and making the seedling guiding portion extend along the seedling conveying direction, the rice transplanting table can be divided into two regions corresponding to the seedling claws from the middle position. When the seedling claws move to the middle position of the rice transplanting table to pick up seedlings, the seedling fixing device blocks the seedlings to prevent the seedlings from swinging to the region corresponding to another seedling claw, reducing the probability of seedling blockage and no seedling dropping, and solving the problem in the prior art that the seedlings swing at the middle position of the rice transplanting table, and the seedling claws cannot pick up the seedlings, resulting in a high probability of seedling blockage and no seedling dropping.

However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features known to the public are not described.

[0026] This application discloses a technical solution for designing a seedling fixing device on a transplanter. The seedling fixing device can assist the stability of the seedlings, prevent the seedlings in the middle position of the seedling planting table from swaying left and right during seedling planting, thereby improving the seedling planting performance and reducing the probability of seedling blockage and non-seeding.

[0027] The seedling fixing device includes: a fixing part 1 and a seedling guiding part 2.

[0028] The fixing part 1 is installed on the back surface of the seedling planting table 4, and the seedling guiding part 2 is arranged at the middle position on the front surface of the seedling planting table 4.

[0029] The seedling guiding part 2 is connected to the fixing part 1 and extends along the seedling conveying direction.

[0030] One end of the fixing part 1 extends along the extending direction of the sliding plate 6, and the other end extends from the sliding plate 6 to the front surface of the seedling planting table 4. The seedling guiding part 2 starts to extend from the part where it extends from the fixing part 1 to the front surface of the seedling planting table 4. This structure can not affect the cooperation between the front surface of the seedling planting table 4 and the seedlings.

[0031] Regarding the connection between the fixing part 1 and the seedling guiding part 2, in this embodiment, the fixing part 1 and the seedling guiding part 2 are fixedly connected. The fixing part 1 and the seedling guiding part 2 can be fixedly connected by an integral structure, welding or riveting, etc. structures, such as Figure 1 As shown, a part of the seedling guiding part 2 is riveted and installed on the fixing part 1 by a rivet 3 and extends along the seedling conveying direction.

[0032] In another embodiment, the fixing part 1 and the seedling guiding part 2 are detachably connected. The fixing part 1 and the seedling guiding part 2 can be detachably connected by a bolt connection or other structures. For example, Figure 2 As shown, the connecting part of the fixing part 1 and the seedling guiding part 2 is a vertical plate. The detachable connection structure such as bolt connection can connect the two from the thickness direction of the fixing part 1 and the seedling guiding part 2, and the connecting part of the fixing part 1 and the seedling guiding part 2 is arranged on the front surface of the seedling planting table 4, which can facilitate the replacement of the seedling guiding part 2 without damaging the seedling planting table 4.

[0033] Regarding the connection between the fixing part 1 and the seedling planting table 4, in this embodiment, a sliding plate 6 is provided on the back surface of the seedling planting table 4, and the fixing part 1 is installed on the sliding plate 6.

[0034] Such as Figure 4The shown seedling fixing device further includes a bolt 7 and a nut 8. The bolt 7 passes through the sliding plate 6 and the fixing part 1, and the bolt 7 and the nut 8 are screwed together to install the fixing part 1 on the sliding plate 6.

[0035] A sliding member 9 is provided on the back surface of the sliding plate 6, and the nut 8 is arranged on the side of the sliding plate 6 away from the sliding member 9. The sliding member 9 is an anti-floating roller of the transplanter. The sliding plate 6 is connected to the rice transplanting table 4. The function of the sliding plate 6 is to support the left and right sliding of the rice transplanting table 4, and the sliding member 9 supports and fixes the sliding plate 6 to prevent the sliding plate 6 from shifting.

[0036] The height of the head of the bolt 7 is higher than the upper end position of the sliding member 9, that is, there is a certain distance between the bottom end of the head of the bolt 7 and the upper end of the sliding member 9.

[0037] One end of the fixing part 1 close to the sliding plate 6 extends along the length direction of the sliding plate 6.

[0038] The fixing part 1 or the sliding plate 6 is provided with a long hole, and the long hole extends along the length direction of the sliding plate 6. The bolt 7 passes through the long hole. As Figure 1 shown, the fixing part 1 is provided with a long hole.

[0039] As Figure 2 shown, the fixing part 1 is arranged on the side of the sliding plate 6 close to the conveyor belt 5, so that the seedling guiding part 2 extends along the seedling conveying direction from one side of the conveyor belt 5.

[0040] Working principle: The conveyor belt 5 conveys the seedlings towards the direction of the seedling claws 10 on the rice transplanting table 4. The two seedling claws 10 reciprocate to pick up the seedlings from the rice transplanting table 4. When the seedling claws 10 move to the middle position of the rice transplanting table 4 to pick up the seedlings, the seedling fixing device blocks the seedlings to prevent the seedlings from swinging to the area corresponding to the other seedling claw 10, which improves the probability of the seedling claws 10 picking up the seedlings.

[0041] In the above embodiment, the front surface of the rice transplanting table 4 refers to the side that cooperates with the seedlings, the back surface of the rice transplanting table 4 refers to the side away from the seedlings, and the back surface of the sliding plate 6 refers to the side away from the rice transplanting table 4.

[0042] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as a limitation of the present invention itself. Various changes can be made in its form and details without departing from the spirit and scope of the present invention defined by the appended claims.
