Description

Technical Field

[0001] This invention relates to a rice transplanter, and more specifically, to a rice transplanter with both manual and electric operation. Background Technology

[0002] Existing rice transplanters have a height-adjustable sub-support at the rear, which is used to hold the seedlings. To control the height of the sub-support, the transplanter has a dedicated control handle with four positions: ascending, neutral, descending, and transplanting, corresponding to different heights of the sub-support. Generally, the control handle uses a purely mechanical method to control the sub-support. With technological advancements, electrically controlled structures have also emerged. However, this type of electrically controlled structure uses a toothed disc meshing mechanism; if a malfunction occurs, the sub-support can no longer be manually operated, and the machine must be towed back to a repair shop for repairs.

[0045] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0046] like Figure 1 and Figure 2As shown, the rice transplanter with both manual and electric operation includes a main support 1, a swingable and liftable auxiliary support 2 at the tail of the main support 1, and an operation component S on the main support 1.

[0047] The operating component S can control the raising and lowering of the sub-support 2 manually or electrically, as will be further explained later.

[0048] like Figures 3 to 8 As shown, the operating component S includes an electric push rod 3. The tail of the electric push rod 3 is provided with a push rod fixing seat 4. The head of the electric push rod 3 is provided with a detachable push rod rocker arm 5. The push rod rocker arm 5 cooperates with a shift spindle 7 through a swing arm 6. The shift spindle 7 is fixed on a shift plate 8. The shift plate 8 is provided with an insertable operating handle 9. The swing arm 6 is also provided with a detachable reset link 10.

[0049] The electric push rod 3 has a push rod connector 31 at its head, and a connector cotter pin 32 is provided on the push rod connector 31.

[0050] The push rod rocker arm 5 includes a cylindrical rocker arm connecting seat 51 and an "L"-shaped rocker arm beam 52. The rocker arm connecting seat 51 has a pair of cylindrical seat connecting holes 511 on its side wall. The cylindrical seat connecting holes 511 cooperate with the cotter pin 32 of the connector. The front end of the rocker arm beam 52 has an elongated through rocker arm slot 521.

[0051] For ease of description later, a neutral position 521A, a front limiting point 521B, and a rear limiting point 521C are provided in the rocker arm slot 521.

[0052] The swing arm 6 includes a swing arm body 60, which has an upper linkage hole 61 and a lower linkage hole 62. The inner wall of the upper linkage hole 61 has a pair of limiting planes 611. The shift spindle 7 passes through the upper linkage hole 61 and is connected to an upper linkage nut 12. The head side wall of the shift spindle 7 has a pair of spindle limiting surfaces 71, which cooperate with the limiting planes 611.

[0053] The reset linkage 10 includes a linkage body 101. The head of the linkage body 101 is provided with a linkage retaining ring 102. A connecting pin 11 passes through the lower linkage hole 62, the linkage retaining ring 102 and the rocker arm slot 521 in sequence. It should be noted that the connecting pin 11 is welded to the rocker arm 6 as a whole.

[0054] In addition, the connecting pin 11 is provided with several gaskets 13.

[0055] The operation of the insertion control handle 9 will be explained below. Figures 10 to 13The diagram shows the relative positional relationship between the insertion control handle 9 and the position display panel M. The user can control the raising and lowering of the sub-support 2 by manually moving the insertion control handle 9.

[0056] The manual operation mode of the operation component S is described below.

[0057] like Figure 10 As shown, the insertion control handle 9 is in the "neutral" position at this time. When the user needs to control the lowering of the sub-support 2, as... Figure 11 As shown, the insertion control handle 9 can be moved forward to reach the "lower" position. During the forward movement of the insertion control handle 9, as... Figure 3 As shown, the shift plate 8 and the shift spindle 7 rotate counterclockwise synchronously, the swing arm 6 rotates counterclockwise around the shift spindle 7 as the center of rotation, and at the same time, the auxiliary support 2 begins to swing downward and descends to the preset height.

[0058] like Figure 3 and 13 As shown, when the operator manually moves the insertion control handle 9 to the "up" position, the reset linkage 10 will move along direction F1. Since a reset spring (not shown) is located at the tail of the reset linkage 10, the reset linkage 10 will automatically reset to the "up" position under the action of the reset spring. Figure 9 The "neutral" position is shown in the image.

[0059] The electric operation mode of the operating component S will be described below.

[0060] like Figure 14 and 15 As shown, at this time, the insertion control handle 9 is in the "neutral" position.

[0061] like Figure 16 and Figure 17 As shown, when the user needs to lower the sub-support 2, the electric push rod 3 can be activated, causing the electric push rod 3 to retract. The push rod rocker arm 5 moves synchronously along direction F2 until the connecting pin 11 slides to the front limit point 521B of the rocker arm slot 521. The electric push rod 3 continues to retract, and the push rod rocker arm 5 pulls the swing arm 6. As a result, the swing arm 6 rotates counterclockwise along direction R1 with the shift main shaft 7 as the rotation center. The swing arm 6 then drives the shift main shaft 7 to rotate counterclockwise. As a result, the insertion control handle 9 rotates counterclockwise along direction R2. When the insertion control handle 9 is rotated to the "lower" position, the sub-support 2 begins to swing downward and descend.

[0062] like Figure 18 and Figure 19As described above, when the auxiliary support 2 descends to the preset height, the electric push rod 3 stops retracting and begins to extend. Simultaneously, the push rod rocker arm 5 moves along direction F3 until the connecting pin 11 slides back to the neutral position 521A of the rocker arm slot 521. At this point, the electric push rod 3 stops extending. Since the connecting pin 11 is in the neutral position 521A, the user can still manually operate the insertion control handle 9, thus easily achieving a coexistence of electric and manual control modes.

[0063] As for how to control the secondary support 2 to the upward or insertion position, the operation steps are basically the same and will not be repeated.

[0064] It should be noted that during the descent or ascent of the sub-support 2, an angle sensor can be installed on the main support 1 or the sub-support 2 to accurately monitor the descent or ascent angle of the sub-support 2. The retraction or extension amplitude of the electric push rod 3 can be controlled based on the feedback signal from the angle sensor to prevent system overload. Of course, the retraction or extension amplitude of the electric push rod 3 can also be directly set using the vehicle's onboard computer.

[0065] like Figure 20 and Figure 21 The figure shows one installation method for an angle sensor. The angle sensor S is fixed to the main bracket 1 via a mounting bracket P. In this case, the angle sensor S monitors the rotation angle of the secondary bracket 2 in real time.

[0066] like Figure 22 and Figure 23 As shown, another implementation of the angle sensor is illustrated. The angle sensor S is replaced by a limit switch, which is fixed to the main bracket 1 via a mounting base Q. In this case, the angle sensor S monitors the rotation angle of the secondary bracket 2 in real time.

[0067] In addition, Figure 20 and Figure 22 In this case, the angle sensor S can also be mounted on the sub-support 2. Of course, the mounting methods for the angle sensor include, but are not limited to, the methods described above.

[0068] This rice transplanter with both manual and electric operation solves the problem that existing rice transplanters cannot operate in both manual and electric modes. It is especially suitable for use in unmanned rice transplanters, enhancing the applicability and ease of use of the transplanter, and ensuring high reliability.

[0069] Not limited to this, any variations or substitutions conceived without inventive effort should be included within the scope of protection of this invention. Therefore, the scope of protection of this invention should be determined by the scope defined in the claims.
