[0035] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] refer to Figure 1-4A simple rice planter includes a movable base 1, a drive structure 2, a sliding plate 3, multiple hoppers 4, and multiple sowing structures 5. The movable base 1 serves as the support and moving foundation for the equipment. The drive structure 2 is located on one side of the movable base 1. The sliding plate 3 is connected to the drive structure 2 and can be manually pushed. The drive structure 2 causes the sliding plate 3 to slide back and forth on the movable base 1. Multiple hoppers 4 are evenly spaced on the movable base 1. There can be three hoppers 4, which store rice seeds. The three hoppers 4 are evenly distributed along the movable frame 11 and move synchronously, forming three rows of sowing in one pass. The specific number can be set according to the actual situation.

[0037] The sowing structure 5 is located between the sliding plate 3 and the hopper 4, which can realize the sowing of rice seeds in the hopper 4.

[0038] In some embodiments, the movable base 1 includes a movable frame 11, two connecting rods 12, and two sliding barrels 13. The movable frame 11 can be a frame structure welded from rectangular steel pipes, and two T-shaped fixing blocks can be symmetrically provided on its top. The sliding plate 3 is provided with a sliding groove that matches the fixing blocks, and the fixing blocks can slide in the sliding groove, so that the sliding plate 3 can perform reciprocating linear motion on the movable frame 11. The two connecting rods 12 can be round steel, symmetrically welded to the end of the movable frame 11 near the drive structure 2. The end of the connecting rod 12 away from the movable frame 11 can be connected to the rotating shaft 21 through a bearing seat to form a stable support fulcrum. The two sliding barrels 13 can be steel cylinders, symmetrically welded to both sides of the bottom of the movable frame 11. The bottom of the sliding barrel 13 can be an outwardly convex arc surface, which can reduce the movement resistance of muddy ground and improve the smoothness of the movement of the movable base 1.

[0039] In some embodiments, the drive structure 2 includes a rotating shaft 21, a rotating disk 22, multiple drive plates 23, and two drive disks 24. The rotating shaft 21 can be a steel shaft, and both ends can be rotatably mounted in the bearing seats of two connecting rods 12 via deep groove ball bearings. The rotating disk 22 can be a cast iron disk, coaxially welded to the middle of the rotating shaft 21. The drive plates 23 can be steel plates, and multiple drive plates 23 are radially and uniformly welded to the edge of the rotating disk 22, which can be 6-8 pieces. The two drive disks 24 are symmetrical and coaxially welded to both ends of the rotating shaft 21. The drive rod 25 can be round steel, and one end can be hinged to the ear plate on the edge of the drive disk 24 via a pin, and the other end can be hinged to the connecting seat on the side of the sliding plate 3 via a ball joint, so as to realize the flexible transmission of the motion direction.

[0040] In some embodiments, the drive structure 2 further includes a push-pull rod 26, which may be a U-shaped seamless steel tube. Its two ends may be hinged to two connecting rods 12. The hinge position may be set according to the actual situation. A rubber grip may be provided in the middle of the push-pull rod 26 to increase the friction between the operator's hand and the push-pull rod 26, making it easier for the operator to apply force to push the equipment to move as a whole.

[0041] In some embodiments, the sowing structure 5 includes a sowing block 51, a sowing opening 52, and a feeding opening 53. The sowing block 51 can be fixed to the top of the sliding plate 3 by bolts, and its end penetrates the side wall of the feeding opening on the side of the hopper 4 away from the driving structure 2. It can slide synchronously with the sliding plate 3 to realize the opening and closing control of the feeding opening. The sowing opening 52 penetrates the movable frame 11 and is aligned with the discharge port of the hopper 4. The feeding opening 53 can be a rectangular through hole, penetrating the side of the sliding plate 3 away from the sowing block 51. Its position corresponds to the sowing block 51 and the sowing opening 52. When the sliding plate 3 slides to the limit position, the feeding opening 53 coincides with the sowing opening 52, which can connect the hopper 4 and the sowing opening 52 to realize the sowing of rice seeds. A gap is left between the bottom opening of the hopper 4 and the sliding plate 3, which can allow the sliding plate 3 to slide smoothly while constraining the rice seeds between the hopper 4 and the sliding plate 3, ensuring that the rice seeds will not flow out from the gap.

[0042] In some embodiments, the sowing structure 5 further includes a material-dispensing plate 54, which may be a steel plate that passes through a strip-shaped hole at the bottom of the hopper 4 along the sliding direction of the sliding plate 3. One end of the plate can be hinged to the top of the sowing block 51, and the other end can slide in the strip-shaped hole and maintain a gap of 1-2 mm with the inner wall of the hopper 4. The material-dispensing plate 54 can slide synchronously with the sowing block 51 to loosen the rice seeds in the hopper 4, avoid the accumulation of rice seeds, and prevent the feeding of the hopper 4 from affecting the sowing.

[0043] In some embodiments, the sowing structure 5 further includes a fixed trough plate 55, a connecting plate 56, and an adjusting component. The fixed trough plate 55 may be a U-shaped steel plate, which is fixed to the sliding plate 3 by bolts and surrounds the outside of the hopper 4. The connecting plate 56 may be a steel plate that matches the inner cavity of the fixed trough plate 55 and can slide along the length of the trough plate. One end of the connecting plate 56 is welded and fixed to the bottom of the sowing block 51. The adjusting component is located between the connecting plate 56 and the fixed trough plate 55 and can adjust the relative position of the sowing block 51 and the discharge port of the hopper 4, thereby adjusting the opening degree of the sowing port 52 and realizing the control of the sowing amount.

[0044] In some embodiments, the adjustment assembly includes an adjustment plate 57, an adjustment screw 58, and an adjustment hole 59. The adjustment plate 57 may be a rectangular steel plate welded to the side of the connecting plate 56 near the fixed groove plate 55, with a bearing mounting hole in its center. One end of the adjustment screw 58 is rotatably connected to the bearing hole of the adjustment plate 57 through a deep groove ball bearing, and the other end passes through the threaded hole of the fixed groove plate 55 to form a screwed engagement. The end of the screw is provided with a butterfly handle. The adjustment hole 59 may be a square hole that passes through the connecting plate 56. The position of the connecting plate 56 on the sliding plate 3 can be adjusted by adjusting the adjustment screw 58, thereby adjusting the overlapping area of ​​the adjustment hole 59 and the seeding port 52, and thus realizing the control of the seeding amount.

[0045] The specific working principle is as follows:

[0046] The operator holds the push-pull lever 26 with both hands and pulls the moving base 1 to move the whole. The two sliding barrels 13 at the bottom of the moving frame 11 contact the ground with the arc surface, which can reduce frictional resistance in muddy fields. With the support and stability of the two connecting rods 12, a single person can push the moving base 1 forward.

[0047] During the forward movement of the movable seat 1, the contact between multiple drive plates 23 and the field causes the rotating disk 22 to rotate, transmitting torque to the rotating shaft 21. The drive disks 24 at both ends of the rotating shaft 21 rotate synchronously with the shaft, and two drive rods 25 are connected to the lugs of the drive disks 24 via pins, converting the circular motion into the linear reciprocating motion of the sliding plate 3: when the hinge point on the drive disk 24 is at its highest point, the drive rod 25 pushes the sliding plate 3 to move away from the drive structure 2; when the hinge point rotates to its lowest point, the drive rod 25 pulls the sliding plate 3 back to its original position.

[0048] The sliding plate 3 engages with the T-shaped fixing block of the movable frame 11 via a bottom groove, achieving stable reciprocating sliding. During this process, the push-pull rod 26 is hinged to the connecting rod 12 via a hinge, allowing for flexible angle adjustment as the equipment moves, ensuring that the operator always maintains a comfortable force application posture.

[0049] When the sliding plate 3 moves toward the driving structure 2, the sowing block 51 slides synchronously through the connecting plate 56, reducing the distance between the sowing block 51 and the inner wall of one side of the hopper 4, thus closing the hopper's discharge port. The temporarily stored seeds move with the sliding plate to the discharge port 53. When the sliding plate 3 moves to its maximum distance, the sowing port 52 and the discharge port 53 gradually overlap, and the seeds fall from the sowing port 52 and the discharge port 53 into the field by gravity, thus achieving sowing. At the same time, the feeding plate 54 slides with the sowing block 51 inside the hopper 4, loosening the accumulated seeds and preventing the formation of arches that cause blockage.

[0050] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
