[0033] Embodiment: Refer to Figure 1-7 An adjustable ditching device for a corn planter as shown, which includes a ditching shovel 1 and a shovel tip 4. A group of groove-expanding plates 5 are rotatably connected to the back surface of the shovel tip 4;
[0034] A fixing block 6 is fixed at the bottom end of the ditching shovel 1. Wedge-shaped grooves 7 are formed on both side surfaces of the fixing block 6. A groove 9 is formed on the upper surface of the shovel tip 4. Wedge-shaped plates 10 are fixed on both groove walls of the groove 9, and the wedge-shaped plates 10 are fixed inside the wedge-shaped grooves 7;
[0035] An adjusting plate 16 is fixed at the inner bottom of the ditching shovel 1. A chute 17 is formed on the adjusting plate 16. A threaded lead screw 19 is rotatably connected in the chute 17, and a slider 18 is slidably fitted in the chute 17. The threaded lead screw 19 penetrates through the slider 18 and is threadedly connected to the slider 18. Swing plates 14 are rotatably connected to the opposite side surfaces of the two groove-expanding plates 5. A column 15 is rotatably connected to the lower surface of the swing plate 14, and the bottom end of the column 15 is rotatably connected to the upper surface of the slider 18. A connecting column 2 is fixed at the top end of the ditching shovel 1, and a mounting plate 3 is fixed at the top end of the connecting column 2. Reinforcing ribs 13 are fixed in both the shovel tip 4 and the inner cavity of the ditching shovel 1.
[0036] In this embodiment, the arrangement of the reinforcing rib 13 improves the structural strength of the ditching shovel 1 and the shovel tip 4. The ditching shovel 1 can be entirely mounted on the bottom frame of the seeder through the mounting plate 3. The cooperative arrangement of the wedge plate 10 and the wedge groove 7 enables the entire fixing block 6 to be tightly fixed inside the groove 9, enhancing the stability of the fixation between the ditching shovel 1 and the shovel tip 4. During seeding, when it is necessary to increase the ditching width of the ditching shovel 1, the screw rod 19 can be rotated to drive the slider 18 to move to the innermost side of the sliding groove 17. At this time, the upright column 15 moves horizontally along with the slider 18. During the movement of the upright column 15, one end of the swing plate 14 will be pushed to move. The swing plate 14 will rotate around the upright column 15 as the axis, causing the other end of the swing plate 14 to push the groove-expanding plate 5 to open. The two groove-expanding plates 5 will open synchronously towards the outside, increasing the width of the planting groove opened by the ditching shovel 1.
[0037] When the screw rod 19 drives the slider 18 to move to the outermost side of the sliding groove 17, the two groove-expanding plates 5 will swing synchronously towards the inside, reducing the width of the planting groove opened by the ditching shovel 1.
[0038] To enable the fixing block 6 to be tightly fixed inside the groove 9, in this embodiment, the fixing block 6 is in sliding fit inside the groove 9. There is a clearance fit between the wedge plate 10 and the wedge groove 7. A set of fixing rods 11 is fixed to the groove wall of the groove 9. A set of through grooves 8 is formed in the fixing block 6. The fixing rods 11 are in sliding fit inside the through grooves 8, and one end of the fixing rod 11 is provided with a threaded section, and a fastening nut 12 is fitted on the threaded section. By sliding the fixing rod 11 through the through groove 8 and tightening the fastening nut 12, the fixing block 6 can be firmly fixed inside the groove 9, realizing the quick fixation of the ditching shovel 1 and the shovel tip 4, and facilitating the disassembly of the shovel tip 4.
[0039] To enable the slider 18 to slide stably inside the sliding groove 17, in this embodiment, the two groove-expanding plates 5 are symmetrically arranged relative to the ditching shovel 1. A set of guide rods 20 is fixed inside the sliding groove 17. The slider 18 is slidably sleeved outside the guide rods 20. One end of the screw rod 19 penetrates through the adjusting plate 16 and is fixed with a knob 21. Hinge seats are fixed on both inner sides of the groove-expanding plate 5. One end of the swing plate 14 is rotatably connected inside the hinge seat. The arrangement of the guide rods 20 enables the slider 18 to slide stably along a straight line inside the sliding groove 17. The arrangement of screwing the knob 21 facilitates controlling the rotation of the screw rod 19. The arrangement of the hinge seat enables the swing plate 14 to be rotatably connected to the groove-expanding plate 5.
[0040] The above description is only a preferred embodiment of the present application and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept of the utility model.
