Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a rice transplanting depth adjustment device for a rice transplanter. Background Art

[0002] Confirming the depth of transplanting is a very important step in the transplanting process. For example, for seedlings at a higher height, their gravity is greater and their roots are longer and deeper, so the transplanting depth can be increased accordingly. When the transplanting height is lower, lodging may occur. For seedlings at a lower height angle, transplanting too deeply may cause more seedlings to fall over and float, inhibiting the seedlings from turning green and tillering.

[0003] In order to control the transplanting depth, the existing depth adjustment device of the rice transplanter, such as a rice transplanter transplanting depth adjustment mechanism with publication number CN215122005U, adjusts the transplanting depth through the clamping relationship of the hinge structure and can effectively fix it in the adjusted state.

[0004] However, although the adjustment mechanism adjusts the downward movement depth of the transplanting chuck, the deeper the chuck moves downward, the deeper the contact between the chuck and the field soil becomes, and the chuck is more likely to be blocked by the soil or entangled by debris. At the same time, the clamping height of the chuck for the seedlings cannot be adjusted. For seedlings with higher heights, the clamping height is too low, which may cause root damage during deep planting and reduce the quality of transplanting. Utility Model Content

[0005] The utility model aims to provide a transplanting depth adjustment device for a rice transplanter, so as to solve the technical problems in the prior art that the chuck is easily blocked by soil when driving the seedlings to be deeply transplanted, and the clamping height between the chuck and the seedlings is difficult to adjust.

[0006] In order to solve the above technical problems, the utility model specifically provides the following technical solutions:

[0007] The utility model provides a transplanting depth adjustment device for a rice transplanter, comprising a first bracket and a second bracket respectively mounted on a seedling tray and a seedling clamp, wherein the first bracket is connected to a transmission member via a rotating motor, and the transmission member rotates with the output shaft of the rotating motor as a radius;

[0008] The second bracket is rotatably connected to a transmission rod through an adjustment component, the seedling clamp is arranged at the end of the transmission rod, the transmission rod and the transmission member are slidably arranged, and the transmission member drives the transmission rod to rotate with the adjustment component as the axis when rotating, and drives the seedling clamp to move up and down;

[0009] Among them, as the rotation radius of the transmission rod changes, the rotation angle of the transmission rod changes, and the displacement size of the seedling clamp changes.

[0010] As a preferred solution of the utility model, a first track is provided in the middle section of the transmission rod, the transmission member is installed on the first track, and the transmission member can slide up and down within the first track at a fixed distance when rotating.

[0011] As a preferred solution of the utility model, a second track is provided at the end of the transmission rod, the second track is connected to the second bracket through the adjustment component, and the adjustment component slides in the second track;

[0012] When the position of the adjusting component in the second track is adjusted, the rotation radius of the transmission rod changes. The larger the rotation radius of the transmission rod, the smaller its rotation angle, and the displacement of the seedling clamp is correspondingly reduced.

[0013] As a preferred solution of the utility model, the adjustment assembly includes a rotating block sleeved on the second track, the rotating block and the second bracket are provided with a connecting piece, and the rotating block rotates on the connecting piece;

[0014] One end of the connecting member is rotatably connected to the rotating block, and the other end of the connecting member is slidably mounted on the second bracket. The connecting member drives the rotating block to slide in the second track to change the rotation radius of the transmission rod.

[0015] As a preferred solution of the utility model, a third track is provided on the second bracket, a screw is provided in the third track, the connecting piece is sleeved and installed on the screw and a thread matching with the screw is provided on the inner wall of the connecting piece;

[0016] The end of the screw rod passes through the third track and is arranged outside the second bracket. When the screw rod is rotated, the connecting member moves in the third track.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The utility model provides a transmission rod at the bottom of the chuck, and a displacement adjustment component is rotatably provided on the transmission rod. The transmission rod is driven by a rotating transmission member to rotate with the adjustment component as the axis. When the adjustment component moves, the rotation radius of the transmission member changes, the rotation angle changes, the height of the chuck moving down changes, and the height of the chuck moving up changes at the same distance at the same time, so that the height of the chuck moving up and the depth of the chuck moving down are changed.

[0019] The utility model can change the height of the seedlings clamped when the transplanting depth is changed, so the utility model is suitable for seedlings of various heights and complies with the transplanting rule that the transplanting depth of high seedlings is deep and the transplanting depth of short seedlings is shallow, thereby reducing the lodging rate of high seedlings and reducing the residual soil on the clamping head when the transplanting depth is increased.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figures 1 to 3 As shown, the utility model provides a transplanting depth adjustment device for a rice transplanter, comprising a first bracket 1 installed on a rice transplanter tray, the first bracket 1 being fixedly arranged on the rice transplanter tray and located on both sides of the rice transplanter tray, a second bracket 2 being arranged at the bottom of the first bracket 1, the second bracket 2 being arranged parallel to the first bracket 1, the second bracket 2 being fixedly arranged between the first bracket 1, the second bracket 2 being located below a rice transplanter seedling chuck, and the second bracket 2 being used for supporting an adjusting member for adjusting the transplanting depth of the rice transplanter seedling chuck.

[0029] A rotating motor 3 is fixedly arranged on the first bracket 1, and the first bracket 1 is connected to a transmission member 4 through the rotating motor 3. The transmission member 4 rotates with the output shaft of the rotating motor 3 as a radius. The transmission member 4 drives the seedling chuck to move up and down during the rotation. During the movement, the seedling chuck moves the seedlings on the seedling tray to the field.

[0030] A transmission rod 6 is vertically arranged on the transmission member 4. The device can be provided with a plurality of transmission rods 6 arranged in parallel, and the transmission rods 6 are connected together for synchronous action. The seedling clamp is arranged at the end of the transmission rod 6, the middle section of the transmission rod 6 is slidably connected to the transmission member 4, and the other end of the transmission rod 6 is rotatably connected to the second bracket 2. The transmission rod 6 is provided with an adjustment component 5, and the adjustment component 5 is used to adjust the rotation radius of the transmission rod 6.

[0031] Among them, as the transmission member 4 rotates, the transmission member 4 slides on the transmission rod 6 with a fixed displacement. The rotation of the transmission member 4 enables the transmission rod 6 to drive the seedling clamp to move up and down at the bottom of the seedling tray. As the rotation radius of the transmission rod 6 changes, the displacement size of the seedling clamp changes accordingly.

[0032] The rotation radius of the transmission rod 6 increases. Since its rotation is driven by the fixed transmission member 4, when the rotation radius of the transmission member 4 remains unchanged, the rotation angle of the transmission rod 6 decreases, so the displacement of the end of the transmission rod 6 decreases, and the planting depth of the seedling clamp at its end decreases.

[0033] Correspondingly, the rotation radius of the transmission rod 6 is reduced. Since its rotation is driven by the fixed transmission member 4, the rotation angle of the transmission rod 6 is increased while the rotation radius of the transmission member 4 remains unchanged. Therefore, the displacement of the end of the transmission rod 6 is reduced, and the planting depth of the seedling clamp at its end is increased.

[0034] No matter how large the displacement of the end of the transmission rod 6 is, the seedling clamp at its end can contact the seedlings on the seedling tray. In particular, when the mud in the field is too soft and the seedling planting depth needs to be deepened, not only does the seedling clamp move downward more deeply, but its seedling clamping height also becomes higher accordingly, thereby facilitating the roots of the seedlings to penetrate deeper into the field, increasing the planting depth and reducing the seedlings from falling over.

[0035] The transmission member 4 can be directly fitted on one of the transmission members 4, and it is recommended to be the transmission member 4 at the end. In order to better limit the moving state of the transmission member 4, a first track 7 is provided in the middle section of the transmission rod 6, and the transmission member 4 is installed on the first track 7. When the transmission member 4 rotates, it can slide up and down at a fixed distance in the first track 7, thereby limiting the relationship between the moving radius of the transmission member 4 and its rotation angle, and ensuring that the distance between the seedling chuck and the seedling tray will not change.

[0036] The transmission rod 6 is connected to the second bracket 2 via an adjustment component 5. The adjustment component 5 can slide on the transmission rod 6. The sliding can be fitted, and the fixing method can be fixed by external bolts.

[0037] Preferably, in order to facilitate the adjustment of the rotation radius of the transmission rod 6, a second track 8 is provided at the end of the transmission rod 6, and the second track 8 is connected to the second bracket 2 through the adjustment component 5, and the adjustment component 5 slides in the second track 8.

[0038] When adjusting the position of the adjusting component 5 in the second track 8, the rotation radius of the transmission rod 6 changes. The larger the rotation radius of the transmission rod 6, the smaller its rotation angle, and the displacement of the seedling chuck decreases accordingly. The smaller the rotation radius of the transmission rod 6, the larger its rotation angle, and the displacement of the seedling chuck increases accordingly.

[0039] The displacement of the seedling clamp is carried out simultaneously up and down, that is, as the depth of the seedling clamp moving down increases, its upward height will also increase, preventing it from being directly stuck on the root of the seedling, making it easier to adapt to seedlings of different heights.

[0040] Furthermore, the adjusting assembly 5 includes a rotating block 501 sleeved on the second track 8 , and a connecting piece 502 is provided on the rotating block 501 and the second bracket 2 , and the rotating block 501 rotates on the connecting piece 502 .

[0041] One end of the connecting member 502 is rotatably connected to the rotating block 501 , and the other end of the connecting member 502 is slidably mounted on the second bracket 2 . The connecting member 502 drives the rotating block 501 to slide in the second track 8 , thereby changing the rotation radius of the transmission rod 6 .

[0042] In order to facilitate the user to adjust the transplanting depth, a third track 503 is provided on the second bracket 2, a screw rod 504 is provided in the third track 503, and the connecting piece 502 is sleeved and installed on the screw rod 504 and a thread matching with the screw rod 504 is provided on its inner wall.

[0043] The end of the screw rod 504 passes through the third track 503 and is arranged outside the second bracket 2. The screw rod 504 is externally arranged on the instrument for easy movement. When the screw rod 504 is rotated, the connecting member 502 moves in the third track 503.

[0044] By means of the transplanting depth adjustment device of the rice transplanter of the present embodiment, the upward movement height and downward movement depth of the seedling clamp can be changed, so that when the transplanting depth changes, the height of the clamped seedlings also changes, which is suitable for seedlings of various heights, reduces the lodging rate of seedlings, and reduces the residual soil on the clamp when the transplanting depth increases.

[0045] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
