[0015] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all of them.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. The embodiments are written in a progressive manner.

[0018] As shown in Figures 1 to 11 A vegetable seedling transplanting mechanism of the present application, which comprises a hopper 1 for containing seedlings and a transfer structure 2 for taking out the seedlings in the hopper 1 and performing transplanting operation; The transfer structure 2 comprises a rotating disc 3, a plurality of connecting arms 4 mounted on the outer circumferential wall of the rotating disc 3, a rotating shaft 5 rotatably mounted on each connecting arm 4, an extension arm 6 connected with the rotating shaft 5, and a clamping unit 7 arranged at the end of the extension arm 6, the clamping unit 7 being used for clamping the seedlings in the hopper 1.

[0019] In the present application, the hopper 1 is used in cooperation with the transfer structure 2, the transfer structure 2 takes out the seedlings in the hopper 1 and transports them to the ground for transplanting operation; the axis of the rotating disc 3 in the transfer structure 2 is horizontal, and the rotating disc 3 performs self-rotation movement, the plane on which the rotating disc 3 lies is coplanar with the advancing direction of the rotating disc 3, so that the plurality of clamping units 7 on the rotating disc 3 can be alternately used in cooperation with the clamping units 7 along the advancing direction of the rotating disc 3; the plurality of connecting arms 4 are annularly distributed on the outer circumferential wall of the rotating disc 3, and can be equidistantly arranged, the connecting arms 4 are mainly used for providing support for the rotating shaft 5, the extension arm 6 and the clamping unit 7 thereon, and increasing the activity interval of the clamping unit 7; the rotating shaft 5 on the connecting arm 4 is rotatable, and its rotation axis is parallel to the axis of the rotating disc 3, the extension arm 6 and the clamping unit 7 can rotate on the connecting arm 4 by means of the rotating shaft 5, so that when the clamping unit 7 grabs the seedlings in the hopper 1, the extension arm 6 can be rotated to the position where the clamping unit 7 is located, and the clamping unit 7 can be used to clamp the seedlings in the hopper 1. Figure 1The extension arm 6 can be at a specified angle with the connecting arm 4 when the clamping unit 7 horizontally grabs, and the extension arm 6 can be collinear with the connecting arm 4 when the rice seedling transplanting work is performed, thereby further increasing the activity range of the clamping unit 7 and facilitating the insertion of the seedlings into the ground.

[0020] In actual use, the hopper 1 and the rotating disc 3 can be installed on a tractor or other agricultural machine, the rotating disc 3 rotates and drives the plurality of clamping units 7 to rotate synchronously, when the clamping unit 7 moves to the seedling taking position on the upper side of the rotating disc 3, the clamping unit 7 corresponds to the position of the hopper 1, the clamping unit 7 grabs the seedlings in the hopper 1, with the rotation of the rotating disc 3, the seedlings are transported to the ground, and in the process, the extension arm 6 rotates on the connecting arm 4 through the rotating shaft 5, so that the extension arm 6 gradually changes from the relative angle state to the collinear state with the connecting arm 4, increases the activity range of the clamping unit 7, and makes the seedlings on the clamping unit 7 close to the ground. When the clamping unit 7 moves to the lower side of the rotating disc 3, the extension arm 6 is collinear with the connecting arm 4, and the total length of the extension arm 6 and the connecting arm 4 allows the clamping unit 7 to insert the seedlings into the ground, thereby completing the rice seedling transplanting work. At this time, the clamping unit 7 stops clamping the seedlings, with the rotation of the rotating disc 3, the clamping unit 7 is separated from the seedlings, and the plurality of clamping units 7 continuously rotate, thereby being able to continuously perform the rice seedling transplanting work.

[0021] It should be pointed out that the seedlings in the hopper 1 are stacked together in a row, as shown in Figure 1 The hopper 1 is inclined, the opening of the hopper 1 towards the transfer structure 2 is tapered, and a seedling taking port is arranged at the tip of the taper, the clamping unit 7 can insert into the hopper 1 through the seedling taking port and clamp the seedlings, and a gap corresponding to the seedling taking port is arranged at the bottom position of the seedling taking port, when the clamping unit 7 rotates, the part of the clamping unit 7 inserted into the seedling taking port and the seedlings can be directly transferred out of the hopper 1 through the gap, thereby facilitating the clamping unit 7 to directly take seedlings in the process of continuous rotation, and there is no need to configure the clamping unit 7 with a movement mode of inserting into the hopper 1 and retracting out of the hopper 1, which is simple in structure and convenient to operate; in order to make the seedling taking port position always have seedlings, a vibration structure can be further arranged for the hopper 1, and the seedlings are always gathered at the seedling taking port position by the inclined arrangement of the hopper 1, and due to the extrusion between the seedlings, the seedlings are not easy to shake off at the seedling taking port position.

[0022] As shown in Figure 1 When performing the rice seedling transplanting work, a plurality of hoppers 1 and a plurality of transfer structures 2 can be arranged, thereby being able to continuously perform the rice seedling transplanting work on multiple rows of seedlings on the ground, and improving the work efficiency.

[0023] The automatic transplanting work of the vegetable seedlings is realized by using the clamping unit 7 to grab the seedlings in the hopper 1 and insert them into the ground, and the several clamping units 7 on the rotating disc 3 continuously rotate, so that the continuous transplanting work of the seedlings is realized, the planting mode of the vegetable seedlings is effectively simplified, the work efficiency is improved, and the consistency of key parameters such as the plant spacing, the depth and the upright degree of the seedlings when planted is improved.

[0024] Further, the end of the extension arm 6 towards the clamping unit 7 is provided with an arc sleeve 8, the arc sleeve 8 is slidably provided with an arc arm 9, the end of the arc arm 9 extends out of the transmission wheel one 10, and the clamping unit 7 is fixed to the end of the arc arm 9.

[0025] When the clamping unit 7 grabs the seedlings, part of the clamping unit 7 is inserted into the hopper 1 through the material taking port of the hopper 1, which requires that the working direction of the clamping unit 7 and the connecting arm 4 form a specified angle, and the material taking port cannot be in the tangential direction of the motion track of the clamping unit 7. Based on this structure, the seedlings grabbed by the clamping unit 7 will form a relative angle with the extension arm 6, rather than being collinear with the extension arm 6. Therefore, when the clamping unit 7 rotates to the lower side of the rotating disc 3, the seedlings are generally in a horizontal or inclined state, rather than being vertical. When directly planted, the seedlings cannot be kept upright. To solve this problem, the above structure can be used, that is, the arc sleeve 8 and the arc arm 9 are used. When the clamping unit 7 moves to the lower side of the rotating disc 3, the arc arm 9 slides in the arc sleeve 8, and the clamping unit 7 moves the seedlings synchronously, so that the seedlings gradually move to a vertical state.

[0026] Further, the clamping unit 7 includes two transmission wheels one 10 rotatably installed at the end of the arc arm 9, each transmission wheel one 10 is provided with a clamping arm 11, and the two transmission wheels one 10 are drivingly provided with a transmission plate 12. The arc arm 9 is provided with a cylinder 13 for providing power for the movement of the transmission plate 12.

[0027] The two transmission wheels one 10 of the clamping unit 7 are directly rotatably installed at the end of the arc arm 9 outside the arc sleeve 8. A groove for installing the cylinder 13 is formed at the end of the arc arm 9. The movable end of the cylinder 13 is connected with the transmission plate 12. Transmission teeth are arranged on the two side walls of the transmission plate 12 and each transmission wheel one 10. In this way, when the cylinder 13 extends and retracts, the two transmission wheels one 10 can be driven to move synchronously and reversely by the transmission plate 12. The two clamping arms 11 can be driven to move relatively by the two transmission wheels one 10, so that the two clamping arms 11 are closed or separated from each other. The two clamping arms 11 are used for clamping the seedlings.

[0028] Further, the extension arm 6 is hollow, and a rotating wheel 14 is rotatably arranged in the extension arm 6. A transmission arm 15 is drivingly arranged on the rotating wheel 14. A slot 16 is formed in the side wall of the arc arm 9, and the end of the transmission arm 15 is rotatably installed in the slot 16.

[0029] When the rotating wheel 14 rotates, it drives the transmission arm 15 to move, and the transmission arm 15 pushes the arc-shaped arm 9 to slide in the arc-shaped sleeve 8. The opening of the slot 16 can increase the movement range of the arc-shaped arm 9 in the arc-shaped sleeve 8, so as to avoid that when the transmission arm 15 is directly installed on the outer wall of the arc-shaped arm 9, the relative position between the transmission arm 15 and the arc-shaped arm 9 limits the movement range of the arc-shaped arm 9.

[0030] Further, the transmission arm 15 is provided with a pressing structure, which comprises a sliding block 17 slidingly arranged on the transmission arm 15, and a sliding rod 18 arranged in a relative rotation manner on the sliding block 17. The sliding rod 18 slides through the extension arm 6 along the radial direction of the rotating wheel 14, and the sliding rod 18 is connected with the extension arm 6 through an elastic body 19.

[0031] In order to keep the rotating wheel 14 and the transmission arm 15 in a transmission state at all times, the transmission arm 15 needs to be pressed on the rotating wheel 14 by means of the pressing structure. Specifically, the elastic body 19 provides the sliding block 17 with an elastic extrusion force through the sliding rod 18, and the sliding block 17 extrudes the transmission arm 15 on the rotating wheel 14. When the transmission arm 15 pushes the arc-shaped arm 9 to move, the angle of the transmission arm 15 changes. At this time, the transmission arm 15 drives the sliding block 17 to rotate on the sliding rod 18, and the sliding block 17 slides relative to the transmission arm 15.

[0032] Further, the rotating disc 3 and the connecting arm 4 are hollow inside. The rotating disc 3 is provided with a fixed disc 20. An annular groove one is formed on one side wall of the fixed disc 20, and the annular groove one is composed of an arc-shaped groove one 21 and a linear groove one 22. A sliding column one 23 is slidingly arranged in the annular groove one. The sliding column one 23 is provided with a movable arm one 24. The movable arm one 24 is slidingly installed in the connecting arm 4 along the length direction of the connecting arm 4. The end of the rotating shaft 5 extends into the connecting arm 4. A transmission wheel two 25 is arranged on the outer wall of the rotating shaft 5 in the connecting arm 4, and the transmission wheel two 25 is in transmission connection with the movable arm one 24.

[0033] The fixed disc 20 is arranged stationary, and the rotating disc 3 can move relative to the fixed disc 20. Since the movable arm one 24 is slidingly installed in the connecting arm 4, the connecting arm 4 can drive the movable arm one 24 to perform a circular motion. The movable arm one 24 drives the sliding column one 23 to slide in the annular groove one. When the sliding column one 23 slides to the position of the arc-shaped groove one 21, the arc-shaped groove one 21 is coaxial with the fixed disc 20, and the distance between the sliding column one 23 and the axis of the fixed disc 20 is fixed. At this time, the movable arm one 24 is stationary relative to the connecting arm 4. When the sliding column one 23 slides into the linear groove one 22, the distance between the sliding column one 23 and the fixed disc 20 changes. At this time, the sliding column one 23 moves relative to the movable arm one 24, and the movable arm one 24 drives the rotating shaft 5 to rotate through the transmission wheel two 25, so as to adjust the angle of the extension arm 6.

[0034] Further, the middle of the rotating shaft 5 is slidably inserted with the movable column 26, one end of the movable column 26 is provided with the threaded rod 27, the middle of the rotating wheel 14 is provided with the threaded hole, the threaded hole is used in cooperation with the threaded rod 27, the other end of the movable column 26 is rotatably provided with the side pushing body 28; the other side wall of the fixed disc 20 is provided with the annular groove two, the annular groove two is composed of the arc-shaped groove two 29 and the linear groove two 30, the movable column 26 is slidably arranged in the annular groove two, the movable column 26 is provided with the movable arm two 32, the movable arm two 32 is slidably arranged in the connecting arm 4 along the length direction of the connecting arm 4, the end of the movable arm two 32 away from the fixed disc 20 is provided with the inclined arm 33, the inclined arm 33 passes through the side pushing body 28 and relatively slides.

[0035] The outer wall of the movable column 26 is provided with the ridge, the movable column 26 is slidably inserted in the rotating shaft 5 through the ridge, so that the movable column 26 and the rotating shaft 5 can synchronously rotate, and the movable column 26 and the rotating shaft 5 can relatively slide; when the connecting arm 4 moves with the rotating disc 3, the connecting arm 4 drives the movable arm two 32 in it to synchronously move, the movable arm two 32 drives the movable column 26 to slide in the annular groove two, when the movable column 26 moves in the arc-shaped groove two 29, the distance between the movable column 26 and the axis of the fixed disc 20 is constant, at this time, the movable arm two 32 is stationary relative to the connecting arm 4, when the movable column 26 moves in the linear groove two 30, the distance between the movable arm two 32 and the axis of the fixed disc 20 changes, the movable arm two 32 moves relative to the connecting arm 4, at this time, the movable arm two 32 drives the side pushing body 28 to move along the axis direction of the rotating shaft 5 through the inclined arm 33, the rotating shaft 5 drives the movable column 26 and the threaded rod 27 to move, the threaded rod 27 drives the rotating wheel 14 to rotate, so as to provide power for the movement of the transmission arm 15 and the arc-shaped arm 9; when the rotating shaft 5 rotates relative to the connecting arm 4, the movable column 26 rotates relative to the side pushing body 28.
