[0016] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0018] Please refer to Figure 1 In an embodiment of the present invention, a soil scraping device for a transplanter planter is provided, including an engine 1, on which a driving mechanism is installed, the driving mechanism is used to make the planter perform circular arc cyclic reciprocating motion, and the planter passes through the scraping mechanism 15 during the movement process, and the soil attached to the surface of the planter is removed by the scraping mechanism 15.

[0019] Specifically, Figure 1-Figure 4 As shown, in the embodiment of the present invention, the engine 1 is a power source, and a motor or the like can also be used to realize power drive, which is used to drive the driving mechanism to operate; wherein, the driving mechanism provided by the present invention comprises a crank 9, a first connecting rod 6 and a second connecting rod 61, and the first connecting rod 6 and the second connecting rod 61 are fixedly connected at two-thirds of the length direction by a connecting rod 62; the same-direction ends of the first connecting rod 6 and the second connecting rod 61 are both connected to the planting rotation; One end of the crank 9 is connected to the driving shaft of the engine 1, and the engine 1 is used to drive the crank 9 to rotate; the other end of the crank 9 is rotatably connected to the third rocker 10, and the third rocker 10 is rotatably connected to the connecting rod 62; the end of the second connecting rod 61 is rotatably connected to the bottom end of the fourth rocker 11, and the top end of the fourth rocker 11 is rotatably connected to the side housing of the engine 1; The end of the first connecting rod 6 is rotatably connected to the triangular connecting plate 4; Furthermore, the driving mechanism further comprises a cam 3, the cam 3 and the first rocker 2 are coaxial structures, and the first rocker 2 is installed on one side of the engine 1; the coaxial cam 3 and the first rocker 2 are both rotatably arranged on the engine 1; the triangular connecting plate 4 is also rotatably connected to the lower end of the first rocker 2 and the lower end of the second rocker 5 respectively; The second rocker arm 5 is a 7-shaped rod structure, the bending portion of the 7-shaped rod structure is rotatably connected to the side wall of the outer shell of the engine 1, and a pulley is provided at the short end of the 7-shaped rod structure, and the outer circumferential side of the cam 3 slides against the pulley.

[0020] Please continue reading Figure 1-Figure 3 In an embodiment of the present invention, the implanter includes a duckbill 8, which is fixedly connected to the bottom of a duckbill connector 7, and both sides of the duckbill connector 7 are rotatably connected to the same-direction ends of the first connecting rod 6 and the second connecting rod 61 respectively.

[0021] The driving mechanism provided in the embodiment of the present invention promotes the duckbill 8 to perform circular reciprocating motion through the mutual cooperation of the crank 9, the first connecting rod 6, the second connecting rod 61, the cam 3, the triangular connecting plate 4, the first rocker 2, the third rocker 10, the fourth rocker 11 and the second rocker 5. During the motion process, the duckbill 8 passes through the scraping mechanism 15, and the mud attached to the surface of the duckbill 8 is removed by the scraping mechanism 15. Among them, the rotation of the crank 9 drives the third rocker 10 to swing back and forth obliquely downward, so that the third rocker 10 drives the second connecting rod 61 to move downward, and at the same time the fourth rocker 11 swings back and forth to drive the second connecting rod 61 to move forward and backward; the engine 1 drives the first rocker 2 to swing back and forth and drives the cam 3 to rotate. During the rotation of the cam 3, it will slide in contact with the pulley of the second rocker 5, driving the second rocker 5 to move forward and backward. The first rocker 2 and the second rocker 5 are connected to the triangular connecting plate 4, thereby driving the first connecting rod 6 to move forward and backward, thereby realizing the duckbill 8 to perform circular reciprocating motion.

[0022] The multi-freedom mechanical arm structure formed by the driving mechanism of the present invention can realize multi-directional and multi-posture movement and has high flexibility and excellent stability.

[0023] Please continue reading Figure 1-Figure 5 In the embodiment of the present invention, the first fixing rod 12 and the second fixing rod 13 are respectively fixedly installed at the bottom of the front and rear ends of the engine 1, wherein the lower end of the second fixing rod 13 is connected to a movable rod 14 through a buffer assembly, and the bottom end of the movable rod 14 is connected to the mud scraping mechanism 15; In addition, the scraper mechanism 15 is also connected to the bottom end of the first fixed rod 12 via a second return spring 16. A second return spring 16 is arranged behind the scraper mechanism 15 to solve the problem of the planter driving the scraper mechanism 15 forward during movement. Through the rapid rebound action of the second return spring 16, the scraper mechanism 15 can be restored to its initial position in time to prevent the inertia force from causing the scraper mechanism 15 to move backward.

[0024] Among them, Figure 3 and Figure 5As shown, the buffer assembly includes a buffer plate 131, which is supported by a plurality of buffer springs 132 and arranged inside the lower end of the second fixed rod 13; the movable rod 14 is rotatably connected to the second fixed rod 13, and when the movable rod 14 rotates relative to the second fixed rod 13, the buffer plate 131 is squeezed, so that the buffer spring 132 is compressed, and therefore, the buffer spring 132 has the ability to reset the movable rod 14.

A rotating connecting plate 153 is symmetrically rotated and connected to the lower end of the hollow connecting plate 152. A brush 154 is fixedly connected to the front end of the rotating connecting plate 153. An irregular rubber brush 155 is arranged at the front end of the brush 154. The brush 154 is connected to the hollow connecting plate 152 through a reinforcing rod 156. A first reset spring 157 is installed between the two brushes 154. The cooperation between the first return spring 157 and the second return spring 16 of the present invention ensures that the device can be stably returned to its original position under different motion states.

[0027] The scraper mechanism 15 provided by the present invention is installed directly below the planter, and the brush 154 of the scraper mechanism 15 adopts an asymmetric rubber brush structure. When the planter passes downward through the scraper mechanism 15, the asymmetric rubber brush is stretched open due to the force, and the built-in first return spring 157 ensures that the rubber brush is quickly returned to its original position after the planter is separated. This structure can efficiently clean the attached soil and avoid the planter from being blocked or stuck.
