Description

Technical Field

[0001] The utility model relates to the technical field of agricultural automation machinery, and particularly relates to a planting component of a transplanter. Background Art

[0002] When the transplanter is working, the planting part needs to drive the seedlings to move left and right, and the whole tray of seedlings is successively grabbed by the seedling claws through the seedling taking port and then planted in the paddy field. During the transplanting season, the transplanter works for a long time, and the planting part needs to move back and forth. At present, in order to make the planting part stable without shaking, there are too many limiting mechanisms. During the movement of the planting part, the friction force generated between the planting part and the limiting mechanism is too large, resulting in excessive consumption of the power of the whole machine and reducing the stability of the whole machine at the same time.

[0003] Grant publication number: CN 216451872 U, application date: November 19, 2021, the utility model name is an integrated planting component for a transplanter, which includes a left support arm and a right support arm. A transverse transmission shaft, a front stop rod and a seedling pressing rod are arranged between the left support arm and the right support arm. A transverse transmission box is arranged in the middle of the transverse transmission shaft. A lower guide rail and an upper guide rail are arranged at the rear of the left support arm and the right support arm. The left support arm and the right support arm are fixedly connected with the upper guide rail, and a planting table is arranged on the upper guide rail. Since a front stop rod is arranged between the left support arm and the right support arm, the smoothness of the movement of the transverse transmission shaft is effectively improved, and thus the smoothness of the sliding of the planting table is effectively improved. The structure is compact and the practicability is strong.

[0004] According to the description of the above prior art specification, the transverse transmission box drives the transverse transmission shaft to make reciprocating motion by using the spiral shaft inside it. At the same time, the transverse transmission shaft drives the left support arm and the right support arm. Then, the left support arm and the right support arm drive the upper guide rail to make reciprocating sliding on the lower guide rail.

[0005] Therefore, in the above prior art, the planting table realizes the movement by reciprocating sliding of the upper guide rail, and the lower surface of the upper guide rail has been sliding on the upper surface of the lower guide rail in a cycle, which not only causes too large friction force, resulting in heating of the upper and lower guide rails, but also excessively consumes the power of the whole machine. Content of the Utility Model

[0006] Aiming at the defects such as large friction force during the reciprocating sliding of the planting table in the prior art and excessive consumption of the power of the whole machine, the purpose of the utility model is to provide a planting component of a transplanter.

[0018] Further, the connecting mechanism is of the same length as the slide rail, and the lengths of both are greater than the length of the first back plate.

[0019] Further, the cross section of the slide rail is in a stepped shape; the upper step is connected to the connecting mechanism, and the lower step is far from the connecting mechanism; there is a gap between the lower step and the bottom end of the planting part, and the gap is used to reduce the friction force between the planting part and the slide rail.

[0020] Further, it further includes a support part, one end of the support part is fixed on the frame of the transplanter, and the other end abuts against the inner side above the planting part; the support part is used to limit the rotation of the planting part around a horizontal axis parallel to the extension direction of the protruding part.

[0041] To further understand the content of the present utility model, the present utility model will be described in detail with reference to the accompanying drawings and embodiments.

[0042] The structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the limited conditions under which the present invention can be implemented. Therefore, they do not have technical essence. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects that the present invention can produce and the purposes that can be achieved, should still fall within the scope that can be covered by the technical content disclosed in the present utility model. At the same time, terms such as "upper", "lower", "left", "right", "middle", etc. cited in this specification are only for the convenience of clear narration and are not used to limit the scope that can be implemented. The change or adjustment of their relative relationships, without substantial change in technical content, should also be regarded as the scope that the present invention can be implemented.

[0043] With the automation of agricultural machinery, automatic seedling planting has been realized at present. The planting part and the seedling claws of a transplanter are the core components of the transplanter. Generally speaking, the seedling claws are used to grab the seedlings and then plant them in the paddy field. The planting part moves left and right relative to the seedling claws, so that the seedling claws can evenly grab the seedlings.

[0044] After the seedling claws grab the seedlings, they will move along a predetermined trajectory to complete the transplanting action. During this process, the movement trajectory, speed and angle of the seedling claws need to be precisely controlled to ensure that the seedlings can be accurately inserted into the soil and remain upright.

[0045] After the seedling claws insert the seedlings into the soil, a seedling pushing device (such as a seedling pusher) will start to push the seedlings out of the seedling claws and fix them in the soil. The force and timing of pushing the seedlings also need to be precisely controlled to avoid damaging the seedlings or affecting the transplanting effect.

[0046] After completing the transplanting action, the seedling claws will return to the initial position along a predetermined trajectory to prepare for the next seedling picking and transplanting. During this process, the seedling claws need to move quickly and smoothly to avoid unnecessary impact and wear on the machine.

[0047] During the return process, the seedling claws will perform a reset operation to ensure that they can be in the correct position and state during the next seedling picking. This usually includes adjusting parameters such as the clamping force, contact area, and angle of the seedling claws.

[0048] In the prior art, the seedling claws are generally arranged on the guide rail, and the planting part slides back and forth left and right along the guide rail, resulting in excessive friction between the planting part and the guide rail, over-consuming the power of the whole machine, and reducing the stability of the whole machine.

[0049] Embodiment 1

[0050] A planting component of a transplanter according to the present application, as Figure 1 shown, includes a sliding component 1, a guide rail component 2, and a planting part 3 for placing seedlings. The positional relationship among the three is as follows: The sliding component 1 is located inside the lower part of the planting part 3 and is connected to the planting part 3. The guide rail component 2 is located below the sliding component 1 and at the bottom of the planting part at the same time. The sliding component 1 drives the planting part 3 to slide along the guide rail component 2, so that the seedling claws sequentially and evenly grab the seedlings on the planting part 3.

[0051] As Figure 2 、 Figure 3 shown, in order to achieve the technical effect that the friction force can be minimized during the relative sliding process of the sliding component 1 and the guide rail component 2, the sliding component 1 includes a first back plate 11. The first back plate 11 is located inside the lower part of the planting part 3, and along the sliding direction of the planting part 3, the length of the first back plate 11 is the same as the length of the planting part 3.

[0052] The sliding component 1 further includes a plurality of sliders 12. The sliders 12 are fixedly connected to the first back plate 11. Therefore, the sliders 12 are connected to the planting part 3 through the first back plate 11, and the sliders 12 drive the planting part 3 to move left and right along the guide rail component 2. The plurality of sliders 12 are evenly arranged along the length direction of the first back plate 11 and are detachably connected to the first back plate 11. One end of the slider 12 is provided with a recess 121, and the recess 121 opens downward.

[0053] As Figure 3 shown, the guide rail component 2 includes a connecting mechanism 21. One end of the connecting mechanism 21 is provided with a convex portion 211. The convex portion 211 is substantially cylindrical. The convex portion 211 is located in the recess 121, and there is a sliding fit gap between the convex portion 211 and the recess 121. The opening distance of the recess 121 is smaller than the cross-sectional circular diameter of the convex portion 211.

[0054] The convex portion 211 and the recess 121 are used in combination to reduce the friction force when the planting part 3 moves relative to the guide rail component 2. At the same time, the sliding component 1 can limit the front-back movement of the planting part 3.

[0055] The guide rail assembly 2 further includes a slide rail 22. The connecting mechanism 21 is fixedly connected to the slide rail 22, and the slide rail 22 is located below the connecting mechanism 21. The slide rail 22 is connected to the slider 12 through the connecting structure 21.

[0056] Along the length extension direction of the convex portion 211, the width of the slider 12 is not greater than 3 cm. Preferably, three sliders 12 are provided. The planting portion 3 moves left and right along the length extension direction of the convex portion 211 through the slider 12.

[0057] In order to ensure that both ends of the planting portion 3 can always be located on the guide rail assembly 2 during the movement process, the connecting mechanism 21 and the slide rail 22 are of the same length, and the length is greater than the lengths of the first back plate 11 and the planting portion 3.

[0058] More specifically, as Figure 3 shown, the cross-section of the slide rail 22 is in a stepped shape. The upper step is connected to the connecting mechanism 21, and the lower step is away from the connecting mechanism 21. At the same time, the lower step is located below the planting portion 3. There is a gap between the lower step and the bottom end of the planting portion 3. On the one hand, it is for installing the seedling claws, and on the other hand, it is also used to reduce the friction between the planting portion 3 and the slide rail 22.

[0059] Embodiment 2

[0060] Embodiment 2 is a further technical solution based on Embodiment 1. One end of the support portion 4 is fixed to the frame of the transplanter, and the other end abuts against the inner side above the planting portion 3. The support portion 4, the frame of the transplanter, and the planting portion 3 generally form a stable triangular support structure. The support portion 4 can limit the rotation of the planting portion 3 around a horizontal axis parallel to the extension direction of the convex portion 211.

[0061] As Figure 1 、 Figure 4 shown, a second back plate 13 is provided on the inner side above the planting portion 3. The second back plate 13 includes a front plate 131 away from the planting portion 3, a rear plate 132 parallel to the front plate 131, and a connecting plate connecting the front plate 131 and the rear plate 132.

[0062] A rolling member is provided at the upper end of the support portion 4. The rolling member is located in the groove formed by the front plate 131 and the rear plate 132. When the planting portion 3 moves left and right along the guide rail assembly 2, the rolling member can roll along the extension direction of the groove. When the rolling member enables the planting portion 3 to move relative to the guide rail assembly 2, the friction generated between the support portion 4 and the planting portion 3 is rolling friction rather than sliding friction, further reducing the friction force received during the relative movement of the planting portion 3. The rolling member is also used to limit the rotation of the planting portion around a horizontal axis, and this horizontal axis is parallel to the extension direction of the convex portion 211.

[0063] More specifically, the rolling element includes a central shaft 41 and an outer ring 42 rotatably connected to the central shaft 41, such that the rolling element can rotate axially about its own axis. The outer ring 41 is located in the groove formed by the front plate 131 and the rear plate 132 and is in contact with the front plate 131 and the rear plate 132.

[0064] To ensure that the outer ring 42 can always roll in the groove formed by the front plate 131 and the rear plate 132, along the reverse extension direction of the convex portion 211, the length of the second back plate 13 is substantially equivalent to the length of the planting portion 3.

[0065] In this application, the sliding fit clearance provided by the convex portion 211 and the concave portion 121, the gap provided between the lower step of the slide rail 22 and the bottom of the planting portion 3, and the rolling mode of the outer ring 42 along the groove formed by the front plate 131 and the rear plate 132 together reduce the frictional force between the planting portion 3 and the guide rail assembly 2, and between the planting portion 3 and the support portion 4.

[0066] By optimizing the connection method, excessive limitation of the planting portion 3 is reduced, the load of the gearbox is decreased, which is beneficial to the operation of the whole machine.

[0067] The above schematically describes the present utility model and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design similar structural modes and embodiments without creative efforts without departing from the creative purpose of the present utility model, they shall fall within the protection scope of the present utility model.
