[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] This utility model provides, for example Figure 1-9The agricultural seeder auxiliary seeding device shown includes a movable frame, which includes a chassis 1 and an auxiliary part. The chassis 1 is provided with an adjustment mechanism and a leveling mechanism, and the leveling mechanism is located at the rear end of the adjustment mechanism.
[0031] The shaft of the external seeder roller is installed on the connecting rod 36. The position of the connecting rod 36 is adjusted by the adjustment mechanism, thereby changing the position of the seeder. The leveling mechanism follows the rear end of the adjustment mechanism, which can level the land after sowing, combining the two processes of sowing and leveling, thus improving work efficiency.
[0032] like Figure 2-5 As shown, the adjustment mechanism includes two lateral shifting components and two upward shifting components, which are symmetrically distributed about the frame 1. Each lateral shifting component includes a control unit and a moving unit. Each control unit includes a second operating box 16 welded to the frame 1, a second rotating shaft 24 fixed to the inner wall of the second operating box 16, a connecting piece 23 rotatably mounted on the second rotating shaft 24, a rocker arm 17 fixed to the top of the connecting piece 23, a positioning part mounted on the rocker arm 17 and the connecting piece 23, a first gear 25 rotatably mounted on the second rotating shaft 24, a second gear 26 rotatably mounted at the bottom of the second rotating shaft 24, and a rack 27 slidably mounted at the bottom of the inner wall of the second operating box 16. The second gear 26 is rotatably mounted inside the second operating box 16. The first gear 25 meshes with the second gear 26, and the second gear 26 meshes with the rack 27. The positioning part includes a push rod 18, a first spring 19, a push plate 20, a lever 22, and two second springs 21. The rocker arm 17 has a through hole for mounting the push rod 18 and the first spring 19. The connecting member 23 has a cavity for mounting the push plate 20, the lever 22, and the two second springs 21. The push rod 18 can move up and down within the rocker arm 17. The two ends of the first spring 19 are fixedly connected to the upper part between the rocker arm 17 and the push rod 18. The push plate 20 is fixedly connected to the bottom end of the push rod 18. The lever 22 is fixedly connected to the bottom of the push plate 20. The two ends of the two second springs 21 are fixedly connected to the connecting member 23 and the push plate 20. The lever 22 is in contact with the first gear 25.
[0033] The rotation is achieved through a revolute joint structure. The first spring 19 and the second spring 21 exert an upward supporting force on the push rod 18 within the rocker arm 17 and the connecting member 23 through their restoring force, which serves to separate the lever 22 from the first gear 25. At this time, rotating the rocker arm 17 is ineffective. Pressing the push rod 18 downward causes the push plate 20 and the lever 22 to move downward with the push rod 18. At this time, the lever 22 engages in the teeth of the first gear 25. Rotating the rocker arm 17 forward or backward causes the connecting member 23 to rotate on the second rotating shaft 24 with the rocker arm 17. The lever 22 rotates with the rocker arm 17 via the push plate 20 and the connecting piece 23. The first gear 25 rotates with the lever 22 on the second rotating shaft 24 with the second rotating shaft 24 as the center. The second gear 26 rotates with the first gear 25. The rack 27 slides back and forth in the groove defined at the bottom of the inner wall of the second operation box 16 with the second gear 26. The rack 27 drives the moving part rotated on it to produce displacement. The top of the second operation box 16 has a sliding opening. The length of the sliding opening serves to prevent the rack 27 from disengaging from the second gear 26.
[0034] like Figure 2 , Figure 4 As shown, both moving parts include a first steel rod 28 rotatably disposed at one end on the front side of the rack 27, a first connecting piece 30 rotatably disposed at the other end of the first steel rod 28, a third rotating shaft 29 rotatably disposed at the front bottom of the frame 1, a second connecting piece 31 fixed to the third rotating shaft 29, a second steel rod 32 rotatably disposed at one end of the second connecting piece 31 away from the third rotating shaft 29, a cylinder 33 rotatably disposed at the other end of the second steel rod 32, a mounting bracket 34 integrally formed at the rear end of the cylinder 33, a long rod 35 detachably connected to the rear end of the mounting bracket 34, and two connecting rods 36 detachably connected to the front end of the long rod 35.
[0035] All rotation settings are achieved through a rotating pair structure. The first steel rod 28 moves back and forth with the rack 27, and the first steel rod 28 drives the first connecting piece 30 to rotate. The third rotating shaft 29 and the second connecting piece 31 rotate with the first connecting piece 30. The second steel rod 32 rotates with the second connecting piece 31. The cylinder 33 moves with the second steel rod 32 and moves linearly left and right under the limit of the sliding rod 42. The mounting frame 34 moves linearly left and right with the cylinder 33, so that the seeder can move left and right with the long rod 35 and the connecting 36 along with the mounting piece 34. The left and right position of the seeder can be controlled by adjusting the rocker arm while sitting on the seat 2, which saves time and effort.
[0036] like Figure 2 , Figure 6As shown, both upward-moving components include a mounting piece 38 rotatably mounted on the side of the frame 1 near the center, a swing arm 37 rotatably mounted on one side of the mounting piece 38, a second gas spring 40 rotatably mounted on the other side of the mounting piece 38, a square plate 41 rotatably mounted on the fixed end of the second gas spring 40, and a steel chain 39 passing through the mounting piece 38. The movable ends of the two second gas springs 40 are respectively rotatably mounted on the opposite sides of the two mounting pieces 38, and the ends of the two steel chains 39 away from the mounting pieces 38 are both passing through the opposite sides of the two mounting brackets 34.
[0037] All rotation settings are achieved through a rotating joint structure. The swing arm 37 moves up and down, and the mounting part 38 rotates with the swing arm 37 around the connection between the mounting part 38 and the frame 1. The steel chain 39 changes position up and down with the mounting part 38. The steel chain 39 drives the mounting frame 34 to move, and the mounting frame 34 drives the cylinder 33 to rotate on the slide rod 42, realizing the up and down rotation of the mounting frame 34 around the slide rod 42. The connecting rod 36 moves with the mounting frame 34 through the long rod 35, realizing the up and down movement of the external seeder by moving the swing arm 37. When the swing arm 37 drives the mounting part 38 to rotate significantly, the second gas spring 40 extends and retracts between the mounting part 38 and the square plate 41 to buffer the impact and reduce the impact wear between parts caused by large-scale movement.
[0038] like Figure 7 , Figure 8 As shown, the leveling mechanism includes a first operating box 6 welded to the rear of the top of the frame 1, a first rotating shaft 9 rotatably disposed inside the first operating box 6, a metal plate 8 fixed to the end of the first rotating shaft 9 away from the first operating box 6, a handle 7 rotatably disposed at the end of the metal plate 8 away from the first rotating shaft 9, a steel cable 10 with one end wound around the first rotating shaft 9, a short rod 11 fixed to the left side of the inner wall of the first operating box 6, a mounting rod 12 sleeved on the other end of the steel cable 10, two rollers 14 detachably connected to the left and right ends of the mounting rod 12, a connecting frame 13 integrally formed in the middle of the mounting rod 12, and two first gas springs 15. The fixed ends of the two first gas springs 15 are respectively rotatably disposed at the rear of the bottom of the frame 1 and distributed to the left and right, and the movable ends of the two first gas springs 15 are respectively rotatably disposed at the top center of the connecting frame 13. A round hole for connecting the first rotating shaft 9 is opened on the right side of the first operating box 6, and the end of the connecting frame 13 away from the mounting rod 12 is rotatably disposed at the front of the bottom of the frame 1.
[0039] All rotation settings are achieved through a rotating pair structure. Rotating the handle 7 causes the metal plate 8 to rotate around the first rotating shaft 9 as the center. The first rotating shaft 9 rotates with the metal plate 8, which in turn retracts or expands the steel cable 10 attached to the upper end of the first rotating shaft 9, thereby enabling the up-and-down movement of the mounting rod 12 attached to the other end of the steel cable 10. The two rollers 14 move up and down with the mounting rod 12. The connecting frame 13 rotates with the mounting rod 12 around the connection point between the connecting frame 13 and the vehicle frame 1 as the center. During the rotation, the first gas spring 15 follows the extension and retraction of the connecting frame 13 to provide buffering, thereby adjusting the up-and-down movement of the rollers 14 in contact with the ground.
[0040] like Figure 1 , Figure 9 As shown, the auxiliary part includes a seat 2 detachably connected to the top rear end of the frame 1, a rear wheel 3 detachably connected to the frame 1, a front bracket 4 detachably connected to the front end of the frame 1, front wheels 5 detachably connected to the left and right ends of the bottom of the front bracket 4, and slide rods 42 welded to the left and right sides of the bottom front end of the frame 1. Two cylinders 33 are respectively fitted onto the two slide rods 42, and both cylinders 33 can slide left and right on the two slide rods 42.
[0041] The operator sits on seat 2 with their feet on the foot pedals on the rear wheel 3 to operate the first control box 6, the second control box 16, and the swing arm 37. The front support 4 improves stability, and the two front wheels 5 and the rear wheel 3 form a triangle with the ground, which also improves stability.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
