Description

Technical Field

[0001] The present application relates to the field of agricultural machinery, and more specifically, to a planting machine. Background Art

[0002] Planting machines refer to automatic sowing equipment used in the production process of crop planting. Planting machines are mainly divided into fully automatic and semi-automatic types. Fully automatic planters are large in size due to their comprehensive functions and are only suitable for large areas of plains. Semi-automatic planters are small in size but have a relatively single application scenario and are less efficient than fully automatic planters. For example, the patent document with the prior art announcement number CN219741176U provides an agricultural planting seeder, which facilitates sowing in two paths at the same time by setting two slotted tubes and a discharge tube, greatly improving the efficiency of sowing. At the same time, the positions of the two slotted tubes can be adjusted by the coordinated use of the adjustment mechanism and the guide rod, so that the sowing position can be adjusted according to the sowing situation, greatly improving the practicality of the seeder.

[0003] In view of the above-mentioned related technologies, the inventor believes that the device cannot be adjusted according to the width of the planting site, and needs to work back and forth many times when facing a wider terrain, which is inefficient and has low applicability. Therefore, we propose a planting machine. Utility Model Content

[0004] In order to improve the problems raised in the above background technology, the present application provides a planting machine.

[0005] The present application provides a planting machine, which adopts the following technical solution:

[0006] A planting machine comprises a connecting seat, a sowing box is fixedly mounted on the connecting seat, two sowing tubes are rotatably connected to the connecting seat, the sowing tubes are connected to the sowing box via the connecting tubes, a plurality of sowing holes are linearly and evenly spaced apart on the sowing tubes, a plurality of adjusting rings are rotatably connected to the sowing tubes, the adjusting rings are used to control the opening and closing of the sowing holes, a bidirectional screw is rotatably connected to the connecting seat, two sliders are slidably fitted on the bidirectional screw, and the sliders are used to drive the sowing tube to rotate.

[0007] By adopting the above technical solution, both ends of the bidirectional bolt are fixedly connected with a handwheel, and turning the handwheel drives the bidirectional screw to rotate, and the two sliders move closer to or away from each other, thereby driving the two sowing tubes to rotate at the same angle. The two sowing tubes can be adjusted and adapted according to the width of the planting site, and the sowing spacing can be adjusted by rotating the adjusting ring, thereby realizing real-time changes according to the planting site, and having wide applicability.

[0008] Optionally, the adjustment ring is arranged at the sowing hole, and a through hole larger than the sowing hole is opened on the adjustment ring.

[0009] By adopting the above technical solution, a rotation damping is provided between the adjusting ring and the sowing tube. The orientation of the through hole can be changed by rotating the adjusting ring. When the through hole coincides with the sowing hole, the seeds can fall downward from the inside of the sowing tube. When the through hole does not coincide with the sowing hole, the seeds cannot fall from there, thereby realizing the change of the sowing spacing by rotating the adjusting ring.

[0010] Optionally, a support rod is hinged on the sliding block, and one end of the support rod is hingedly matched with the sowing tube.

[0011] By adopting the above technical solution, when the bidirectional screw drives the slider to slide, the slider cooperates with the support rod to drive the sowing tube to rotate, and the two sowing tubes cooperate to change the sowing range.

[0012] Optionally, a connecting rod is slidably connected in the sowing tube, a plurality of push plates are fixedly connected to the connecting rod, and a motor is fixedly installed on the sowing box, and the motor is used to drive the connecting rod to slide reciprocally.

[0013] By adopting the above technical solution, the motor can drive the connecting rod to perform reciprocating motion, so that the connecting rod drives the push plate to move in the sowing tube. On the one hand, the seeds entering the sowing tube through the connecting tube can be evenly spread in the sowing tube. On the other hand, the sowing holes can be dredged to achieve uniform seed falling and improve sowing uniformity.

[0014] Optionally, the motor output end is fixedly connected to a gear A, gears B are meshingly connected on both sides of the gear A, a turntable is coaxially connected to the gear B, the turntable is rotatably connected to the sowing tube, and a drive rod is eccentrically connected to the turntable, a drive seat is slidably fitted on the drive rod, and the drive seat is fixedly connected to one end of the connecting rod.

[0015] By adopting the above technical solution, gear A drives gear B and the turntable to rotate, and the driving rod drives the driving seat to move when rotating. Since the connecting rod and the sowing tube slide together, the driving seat drives the connecting rod to slide back and forth.

[0016] In summary, the present application includes at least one of the following beneficial technical effects:

[0017] 1. By rotating the bidirectional screw, the slider and the support rod cooperate to drive the two sowing tubes to rotate at the same angle. The two sowing tubes cooperate to adjust the sowing range. The adjusting ring is rotated to adjust the overlap between the through hole and the sowing hole to change the sowing spacing. It can be flexibly adjusted and adapted according to the width of the planting site, and has a wide applicability.

[0018] 2. The push plate is driven by the connecting rod to slide back and forth in the sowing tube. On the one hand, the seeds entering the sowing tube through the connecting tube can be evenly spread in the sowing tube. On the other hand, the sowing holes can be dredged to prevent the seeds from clogging the sowing holes, so that the seeds can fall evenly, the sowing uniformity can be improved, and the practicality can be improved.

[0024] The present application is further described in detail below in conjunction with the accompanying drawings.

[0025] Reference Figure 1-4 The present application includes a connecting seat 1, on which a seeding box 2 is fixedly mounted, and two seeding tubes 3 are rotatably connected to the connecting seat 1, and the seeding tube 3 is connected to the seeding box 2 through a connecting tube 4. A plurality of seeding holes are linearly and evenly spaced on the seeding tube 3, and a plurality of adjusting rings 5 ​​are rotatably connected to the seeding tube 3. The adjusting ring 5 is used to control the opening and closing of the seeding holes, and a bidirectional screw 7 is rotatably connected to the connecting seat 1. Two sliders 8 are slidably fitted on the bidirectional screw 7, and the slider 8 is used to drive the seeding tube 3 to rotate, and hand wheels are fixedly connected to both ends of the bidirectional bolt 7. Rotating the hand wheel drives the bidirectional screw 7 to rotate, and the two sliders 8 move closer to or away from each other, thereby driving the two seeding tubes 3 to rotate at the same angle, and the two seeding tubes 3 can be adjusted and adapted according to the width of the planting site, and then the sowing spacing is adjusted by rotating the adjusting ring 5, so as to realize real-time changes according to the planting site, and the applicability is wide.

[0026] Reference Figure 1 One end of the sowing tube 3 away from the sowing box 2 is rotatably connected to a supporting roller, which provides support for the sowing tube 3 and controls the distance between the sowing tube 3 and the ground.

[0027] Reference Figure 3 The adjusting ring 5 is arranged at the sowing hole, and a through hole 6 larger than the sowing hole is opened on the adjusting ring 5. A rotation damping is arranged between the adjusting ring 5 and the sowing tube 3. Rotating the adjusting ring 5 can change the orientation of the through hole 6. When the through hole 6 coincides with the sowing hole, the seeds can fall from the sowing tube 3 to the lower side. When the through hole 6 does not coincide with the sowing hole, the seeds cannot fall from there, thereby realizing the change of the sowing spacing by rotating the adjusting ring 6.

[0028] Reference Figure 2 A support rod 9 is hinged on the slider 8, and one end of the support rod 9 is hinged with the sowing tube 3. When the bidirectional screw 7 drives the slider 8 to slide, the slider 8 cooperates with the support rod 9 to drive the sowing tube 3 to rotate. The cooperation of the two sowing tubes 3 can change the sowing range.

[0029] Reference Figure 3 A connecting rod 10 is slidably connected in the sowing tube 3, and a plurality of push plates 11 are fixedly connected to the connecting rod 10. A motor 12 is fixedly installed on the sowing box 2. The motor 12 is used to drive the connecting rod 10 to slide back and forth. The motor 12 can drive the connecting rod 10 to reciprocate, so that the connecting rod 10 drives the push plate 11 to move in the sowing tube 3. On the one hand, the seeds entering the sowing tube 3 through the connecting tube 4 can be evenly spread in the sowing tube 3. On the other hand, the sowing holes can be dredged to achieve uniform seed dropping and improve sowing uniformity.

[0030] Reference Figure 4 The output end of the motor 12 is fixedly connected with a gear A13, and both sides of the gear A13 are meshed with gears B14. A turntable 15 is coaxially connected to the gear B14. The turntable 15 is rotatably connected to the sowing tube 3, and a driving rod 16 is eccentrically connected to the turntable 15. A driving seat 17 is slidably fitted on the driving rod 16. The driving seat 17 is fixedly connected to one end of the connecting rod 10. The gear A12 drives the gear B13 and the turntable 14 to rotate. When the driving rod 16 rotates, it drives the driving seat 17 to move. Since the connecting rod 10 slides with the sowing tube 3, the driving seat 17 drives the connecting rod 10 to slide back and forth.

[0031] When the rotation connection of the sowing tube 3 connection seat and the center of the gear B13 are located on the same axis, the gear B13 is always meshed with the gear A12 when the sowing tube 3 rotates.

[0032] The implementation principle of a planting machine in an embodiment of the present application is as follows: after the connecting seat 1 is connected to the external traction agricultural machinery, the seeds are adjusted into the seeding box 2, and the seeds enter the seeding tube 3 through the connecting tube 4. The hand wheel is turned to make the bidirectional screw 7 drive the slider 8 to slide, and the slider 8 cooperates with the support rod 9 to drive the seeding tube 3 to rotate. The two seeding tubes 3 cooperate to be adapted and adjusted according to the width of the planting site, and then the adjustment ring 5 is rotated to adjust the opening number of seeding holes and the seeding spacing. When the traction agricultural machinery moves, the motor 12 rotates, and the gear A12 drives the gear B13 and the turntable 14 to rotate. When the drive rod 16 rotates, it drives the drive seat 17 to move, so that the connecting rod 10 drives the push plate 11 to move in the seeding tube 3, so that the seeds entering the seeding tube 3 through the connecting tube 4 are evenly spread in the seeding tube 3, and the seeding holes are dredged to achieve uniform seed dropping.
