Description

Technical Field

[0001] This invention relates to the field of various crop seeders, and more specifically, to a high-efficiency seeder suitable for planting various crops. Background Technology

[0002] In agricultural production, crop seeds need to be sown using seeders. Seeders are an essential auxiliary tool for large-scale sowing and are widely used. When the existing equipment is in operation, one type of seeder can only sow for specific seeds. If different seeds are to be sown, different seeders need to be used, which makes the sowing cost high. Moreover, when changing seeds, it is inconvenient to collect the remaining seeds, which may even lead to waste. Based on this, the present invention discloses a high-efficiency seeder suitable for sowing various crops. Summary of the Invention

[0003] To address the problems mentioned in the background art, where existing seeders can only sow specific seeds and require different seeders for different seeds, resulting in high sowing costs and inconvenience and waste when changing seeds, this invention provides a high-efficiency seeder suitable for sowing multiple crops. It includes a hopper with a feed cylinder fixed to its bottom. A replacement assembly is installed on the feed cylinder, comprising a structural cavity, a pulling cavity, a rotating hole, a mounting base, a rotating shaft, a mounting cylinder, and a mounting cavity. The feed cylinder has a rotating roller and an insertion hole. A structural cavity is formed inside the feed cylinder, and a pulling cavity is formed at the bottom of the structural cavity. A rotating hole is formed through the vertical surface of one end of the inner wall of the pulling cavity. A mounting base is installed on the outer vertical surface of one end of the feed cylinder at the position where the rotating hole is located. A rotating shaft is rotatably mounted inside the rotating hole. One end of the rotating shaft is inserted into the pulling cavity. A mounting cylinder is fitted around the cross-section of the rotating shaft. A mounting cavity is formed inside the mounting cylinder. A rotating roller is mounted on the rotating shaft. An insertion hole parallel to the center line is formed at the center position of the rotating roller. The rotating roller is fitted around the cross-section of the rotating shaft through the insertion hole. A fixing component is installed on the vertical surface of one end of the feed cylinder, and a collecting component is installed on one side cross-section of the feed cylinder.

[0004] As a further improvement to this technical solution, the replacement component also includes a limiting strip, a limiting groove, a pulling groove, a pulling rod, a connecting short shaft, a slot, and a locking block. Limiting strips are symmetrically fixed to both sides of the outer surface of the mounting cylinder. Limiting grooves are symmetrically formed on both sides of the inner wall of the pulling cavity. The limiting strips move along the limiting grooves. The mounting cylinder is inserted into the pulling cavity through the limiting strips. Slots are symmetrically formed on the shaft of the rotating shaft. Locking blocks are symmetrically fixed to the arc surface of the inner wall of the insertion hole. The locking blocks move along the slots. A pulling groove is formed on the vertical surface of the end of the rotating shaft away from the rotating hole. A pulling rod is slidably arranged inside the pulling groove. A connecting short shaft is fixed to the end of the pulling rod away from the rotating shaft. Slots are symmetrically formed on the shaft of the connecting short shaft. The slots on the connecting short shaft and the rotating shaft are in the same position. When the pulling rod is fully inserted into the pulling groove, the connecting short shaft contacts the rotating shaft, and the slots on it fit together perfectly.

[0005] As a further improvement to this technical solution, a discharge pipe is fixedly connected to the bottom of the feed cylinder, and a leakage chamber is opened inside the discharge pipe. The top of the leakage chamber is connected to the pulling chamber.

[0006] As a further improvement to this technical solution, the cross-sectional diameter of the rotating roller is smaller than the cross-sectional diameter of the mounting cavity. The top of the mounting cylinder is provided with a feed inlet. The mounting cavity is connected to the structural cavity through the feed inlet. Brushes are fixed to both sides of the feed inlet. The bottom of the brushes is in contact with the rotating roller. The bottom of the mounting cylinder is provided with a discharge outlet. The mounting cavity is connected to the leakage cavity through the discharge outlet.

[0007] As a further improvement to this technical solution, the end of the rotating shaft away from the connecting short shaft extends outward through the mounting base and is equipped with a first gear via the connecting shaft. A small motor is mounted on the vertical surface of the mounting base in the pulling cavity, and a second gear is mounted on the output shaft end of the small motor. The second gear meshes with the first gear.

[0008] As a further improvement to this technical solution, the fixing assembly includes a screw hole, a closing plate, a push rod, a ball bearing, a bolt rod, a rotary knob, and a buckle. A screw hole is provided at the center of the vertical end face of the connecting short shaft away from the rotating shaft. A closing plate is provided at the opening position of the pulling cavity away from the rotating hole. A bolt rod is provided in the middle of the working surface of the closing plate. One end of the bolt rod is threaded, and the other end of the bolt rod extends out of the outside through the body of the closing plate and is connected to a rotary knob. Push rods are symmetrically fixed on both sides of the bolt rod on the working surface of the closing plate. A ball bearing is rotatably installed at the working end of the push rod.

[0009] As a further improvement to this technical solution, buckles are symmetrically installed on the vertical end face of the feed cylinder away from the mounting base at positions above and below the opening of the pulling cavity. When the closing plate is placed inside the pulling cavity, the bolt rod can rotate and insert into the screw hole, the rolling ball contacts the end face of the rotating roller, and the buckles can rotate and press tightly against the closing plate.

[0010] As a further improvement to this technical solution, the collecting assembly includes a structural frame, a connecting groove, a fixed inclined plate, a pulling hole, a stretching plate, and a connecting block. A fixed inclined plate is installed on one vertical surface of the inner wall of the structural cavity, and a connecting groove is opened through the other vertical surface of the inner wall of the structural cavity. A structural frame is fixedly connected to the upper oblique position of the mounting cylinder. When the mounting cylinder is fully inserted into the pulling cavity, the structural frame is inserted into the connecting groove. The height of the vertical plate of the structural frame is the same as the opening height of the connecting groove. The working range of the top inclined plate of the structural frame is equal and symmetrical with the working range of the fixed inclined plate.

[0011] As a further improvement to this technical solution, a pulling hole is provided at the upper part of the vertical surface of the feeding cylinder where the mounting base is installed. A stretching plate is installed on the outer vertical surface of the feeding cylinder at the opening position of the pulling hole. The stretching end of the stretching plate passes through the pulling hole and is inserted into the interior of the structural cavity. A connecting block is fixed to the end of the stretching plate inserted into the structural cavity. The connecting block is connected to the end of the cylinder body of the mounting cylinder.

[0012] The collecting assembly also includes a fixed rod, a sliding plate, and a receiving hopper. The fixed rod is fixedly connected to the vertical surface of the feed cylinder with a connecting groove. The fixed rod is located below the opening of the connecting groove. A sliding groove is opened at the bottom of the fixed rod, and a sliding plate is installed inside the sliding groove. The receiving hopper is connected to the sliding plate.

[0013] 1. This high-efficiency seeder, suitable for sowing various crops, allows for the rapid replacement of key structural components for sowing and feeding by changing the cooperative operation of components, eliminating the need to change to different types of seeders and saving sowing costs.

[0014] 2. In this high-efficiency seeder suitable for sowing various crops, the fixed components work together to fix the rotating roller, ensuring that the sowing of different seeds can be carried out smoothly.

[0015] 3. In this high-efficiency seeder suitable for sowing various crops, the collection components work together to collect the remaining unsown seeds while changing different sowing structures, thus avoiding waste and saving production costs. Attached Figure Description

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Therefore, this invention provides a high-efficiency seeder suitable for sowing various crops, see [link to relevant documentation]. Figure 1 - Figure 6As shown, it includes a discharge hopper 1, a feed cylinder 2 fixedly connected to the bottom of the discharge hopper 1, a replacement assembly installed on the feed cylinder 2, the replacement assembly including a structural cavity 3, a pulling cavity 4, a rotating hole 5, a mounting base 6, a rotating shaft 7, a mounting cylinder 8, a mounting cavity 9, a rotating roller 18, and an insertion hole 19. The feed cylinder 2 has a structural cavity 3 inside, a pulling cavity 4 at the bottom of the structural cavity 3, a rotating hole 5 through the vertical surface of one end of the inner wall of the pulling cavity 4, a mounting base 6 installed on the vertical surface of one end of the feed cylinder 2 at the position of the rotating hole 5, a rotating shaft 7 rotatably installed inside the rotating hole 5, one end of the rotating shaft 7 inserted into the pull cavity 4, a mounting cylinder 8 sleeved on the outside of the cross section of the rotating shaft 7, a mounting cavity 9 inside the mounting cylinder 8, a rotating roller 18 installed on the rotating shaft 7, an insertion hole 19 parallel to the center line opened at the center position of the rotating roller 18, and the rotating roller 18 sleeved on the outside of the cross section of the rotating shaft 7 through the insertion hole 19. The replacement components also include a limiting strip 10, a limiting groove 11, a pulling groove 14, a pulling rod 15, a connecting short shaft 16, a retaining groove 17, and a retaining block 20. Limiting strips 10 are symmetrically fixed to both sides of the outer surface of the mounting cylinder 8. Limiting grooves 11 are symmetrically formed on both sides of the inner wall of the pulling cavity 4. The limiting strips 10 move along the limiting grooves 11, and the mounting cylinder 8 is inserted into the pulling cavity 4 through the limiting strips 10. Retaining grooves 17 are symmetrically formed on the shaft of the rotating shaft 7. Retaining blocks 20 are symmetrically fixed to the inner arc surface of the insertion hole 19. The rotating shaft 7 moves along the slot 17. A pull groove 14 is provided on the vertical surface of the end away from the rotating hole 5. A pull rod 15 is slidably arranged inside the pull groove 14. A connecting short shaft 16 is fixedly connected to the end of the pull rod 15 away from the rotating shaft 7. Slots 17 are symmetrically provided on the shaft of the connecting short shaft 16. The slots 17 on the connecting short shaft 16 and the rotating shaft 7 are located in the same position. When the pull rod 15 is fully inserted into the pull groove 14, the connecting short shaft 16 contacts the rotating shaft 7, and the slots 17 on it are properly aligned and connected. The limiting groove 11 and the limiting strip 10 can ensure that the mounting cylinder 8 moves into the pull cavity 4 at a fixed angle, while ensuring that the mounting cylinder 8 will not rotate with the rotating shaft 7. When installing the rotating roller 18, the rotating roller 18 can be used to push the locking block 20 into the locking groove 17 connecting the short shaft 16, ensuring that the locking block 20 can enter the locking groove 17 of the rotating shaft 7 along a predetermined trajectory, so as to push the rotating roller 18 to the outside of the cross section of the rotating shaft 7 at a fixed angle, while ensuring that the rotating roller 18 can rotate with the rotating shaft 7, so as to achieve the effect of rotating the rotating roller 18 while the mounting cylinder 8 remains stationary.

[0020] A discharge pipe 12 is fixedly connected to the bottom of the feed cylinder 2. A leakage chamber 13 is opened inside the discharge pipe 12, and the top of the leakage chamber 13 is connected to the pulling chamber 4. Seeds falling from the mounting cylinder 8 can be discharged to the outside through the leakage chamber 13, ensuring the smooth progress of the sowing operation.

[0021] The cross-sectional diameter of the rotating roller 18 is smaller than that of the mounting cavity 9. A feed inlet 31 is provided at the top of the mounting cylinder 8, and the mounting cavity 9 is connected to the structural cavity 3 through the feed inlet 31. Brushes 32 are fixed to both sides of the feed inlet 31, with the bottom of the brushes 32 contacting the rotating roller 18. A discharge outlet 33 is provided at the bottom of the mounting cylinder 8, and the mounting cavity 9 is connected to the leakage cavity 13 through the discharge outlet 33. Seeds can enter the loading groove of the rotating roller 18 through the feed inlet 31. Under the constraint of the brushes 32, the rotating roller 18 is filled with an appropriate amount of seeds, which can be evenly distributed into the mounting cavity 9. Seeds falling into the mounting cavity 9 can enter the leakage cavity 13 through the discharge outlet 33, achieving a smooth distribution effect.

[0022] The end of the rotating shaft 7 away from the connecting short shaft 16 extends outward through the mounting base 6 and is connected to a first gear 28 via a connecting shaft. A small motor 29 is mounted on the vertical surface of the mounting base 6 in the pulling cavity 4. A second gear 30 is mounted on the output shaft end of the small motor 29, and the second gear 30 meshes with the first gear 28. When the small motor 29 is started, the second gear 30 rotates, and the first gear 28 rotates accordingly, driving the rotating shaft 7 and the rotating roller 18 to rotate. This provides the driving force for the rotation of the rotating roller 18, and the rotation speed of the rotating roller 18 can be adjusted by the small motor 29, thereby adjusting the seed planting position distance to meet the growth needs of different seeds.

[0023] During operation, by changing the components in coordination, when sowing different seeds, a pulling force is applied to the mounting cylinder 8 inside the pulling cavity 4. The mounting cylinder 8 drives the rotating roller 18 inside it to move outward. Then, an outward pulling force is applied to the rotating roller 18, which drives the locking block 20 to move outward along the locking groove 17 until the rotating roller 18 disengages from the shaft of the rotating shaft 7 and the connecting short shaft 16. Then, a rotating roller 18 of appropriate specifications is selected, and the rotating roller 18 is fitted outside the cross section of the connecting short shaft 16 using the insertion hole 19, so that the locking block 20 enters the locking groove 17. A pushing force is applied to the rotating roller 18 toward the mounting cylinder 8, so that the rotating roller 18 enters the interior of the mounting cavity 9, and the pulling rod 15 is fully inserted into the pulling groove 14. Then, a pushing force is applied to the mounting cylinder 8. Under the limiting action of the limiting strip 10 and the limiting groove 11, the mounting cylinder 8 drives the rotating roller 18. The rotating roller 18 is fixed in the working position by the fixing component, which allows for quick replacement of different models of rotating roller 18 to meet the sowing needs of different types of seeds without the need to change to different types of seeders, thus saving sowing costs. Finally, the small motor 29 is started, the second gear 30 rotates, which drives the first gear 28 and the rotating shaft 7 to rotate, and the rotating roller 18 rotates. With the cooperation of the discharge pipe 12, the seeds are sown evenly.

[0024] Further, see Figure 2 , Figure 5 - Figure 7 As shown, a fixing assembly is installed on the vertical surface of one end of the feed cylinder 2. The fixing assembly includes a screw hole 21, a closing plate 22, a push rod 23, a ball bearing 24, a bolt rod 25, a rotary knob 26, and a buckle 27. The screw hole 21 is located at the center of the vertical end face of the connecting short shaft 16 away from the rotating shaft 7. The closing plate 22 is located at the opening position of the pulling cavity 4 away from the rotating hole 5. The bolt rod 25 is located in the middle of the working surface of the closing plate 22. One end of the bolt rod 25 is threaded, and the other end of the bolt rod 25 extends out of the body of the closing plate 22 and is connected to the rotary knob 26. Push rods 23 are symmetrically fixed on both sides of the bolt rod 25 on the working surface of the closing plate 22. The working end of the push rod 23 is rotatably mounted with a ball bearing 24. The unthreaded part of the bolt rod 25 can rotate on the body of the closing plate 22. When the ball bearing 24 is in close contact with the rotating roller 18, the connecting short shaft 16 contacts the rotating shaft 7, and the threaded end of the bolt rod 25 is fully inserted into the screw hole 21.

[0025] On the vertical end face of the feed cylinder 2 away from the mounting base 6, there are symmetrically installed buckles 27 at the positions above and below the opening of the pulling cavity 4. When the closing plate 22 is placed inside the pulling cavity 4, the bolt rod 25 can rotate and be inserted into the screw hole 21, the rolling ball 24 contacts the end face of the rotating roller 18, and the buckle 27 can rotate and press tightly on the closing plate 22.

[0026] During operation, through the coordinated operation of the fixed components, after the rotating roller 18 is installed into the mounting cavity 9 and the mounting cylinder 8 is pushed into the pulling cavity 4, the closing plate 22 is fitted into the opening position of the pulling cavity 4. The rolling ball 24 contacts the end face of the rotating roller 18, allowing the rotating roller 18 to fully enter the interior of the mounting cavity 9. Then, a rotational force is applied to the rotating knob 26, and the bolt rod 25 rotates and inserts into the screw hole 21. At the same time, the buckle 27 is rotated, so that the buckle 27 is pressed tightly against the plate body of the closing plate 22, and the rolling ball 24 is pressed tightly against the rotating roller 18, so that the rotating roller 18 can rotate stably, ensuring the smooth progress of the sowing operation.

[0027] Among them, see Figure 1 - Figure 5 , Figure 8 - Figure 9As shown, a collecting assembly is installed on one side of the feed cylinder 2. The collecting assembly includes a structural frame 34, a connecting groove 35, a fixed inclined plate 36, a pulling hole 37, a stretching plate 38, and a connecting block 39. A fixed inclined plate 36 is installed on one vertical surface of the inner wall of the structural cavity 3, and a connecting groove 35 is opened through the other vertical surface of the inner wall of the structural cavity 3. The structural frame 34 is fixedly connected to the upper part of the mounting cylinder 8. When the mounting cylinder 8 is fully inserted into the pulling cavity 4, the structural frame 34 is inserted into the connecting groove 35. The height of the vertical plate of the structural frame 34 is the same as the opening height of the connecting groove 35. The working range of the top inclined plate of the structural frame 34 is equal and symmetrical with the working range of the fixed inclined plate 36. When the rotating roller 18 rotates, the mounting cylinder 8 is stationary inside the pulling cavity 4, and the structural frame 34 is stationary inside the connecting groove 35, ensuring the airtightness of the structural cavity 3 during operation.

[0028] A pulling hole 37 is provided on the upper part of the vertical surface of the feeding cylinder 2 where the mounting base 6 is installed. A stretching plate 38 is installed on the outer vertical surface of the feeding cylinder 2 at the opening position of the pulling hole 37. The stretching end of the stretching plate 38 passes through the pulling hole 37 and is inserted into the structural cavity 3. A connecting block 39 is fixed to the end of the stretching plate 38 inserted into the structural cavity 3. The connecting block 39 is connected to the end of the cylinder body of the mounting cylinder 8. When the mounting cylinder 8 is completely pulled out of the outside, the pulling end of the stretching plate 38 contacts the vertical end face of the inner wall of the pulling cavity 4. When the stretching plate 38 enters the structural cavity 3, the structural surface of the stretching plate 38 near the fixed inclined plate 36 contacts the fixed inclined plate 36. The fixed inclined plate 36 and the stretching plate 38 can separate the space between the structural cavity 3 and the pulling cavity 4 during the replacement of the rotating roller 18, ensuring that the seeds accumulated on the fixed inclined plate 36 enter the top of the stretching plate 38 and flow out through the connecting groove 35, preventing the seeds from falling into the interior of the pulling cavity 4.

[0029] The collection assembly also includes a fixed rod 40, a sliding plate 41, and a receiving hopper 42. The fixed rod 40 is fixedly attached to the vertical surface of the feed cylinder 2, where a connecting groove 35 is formed. The fixed rod 40 is located below the opening of the connecting groove 35. A groove is formed at the bottom of the fixed rod 40, and the sliding plate 41 is installed inside the groove. The receiving hopper 42 is connected to the sliding plate 41. After the seeds fall into the receiving hopper 42 through the connecting groove 35, a pushing force is applied to the sliding plate 41 by the receiving hopper 42. The sliding plate 41 disengages from the groove at the bottom of the fixed rod 40, thus emptying and collecting the seeds inside the receiving hopper 42, preventing waste.

[0030] During operation, the structural design of the fixed components allows for the application of a pulling force to the mounting cylinder 8 when the rotating roller 18 is replaced. The mounting cylinder 8 moves outward, causing the connecting block 39 to pull the stretching end of the stretching plate 38 to move accordingly. Simultaneously, the structural frame 34 moves along with the mounting cylinder 8, opening the opening of the connecting groove 35. The remaining seeds on the top of the fixed inclined plate 36 and the first gear 28 will then fall into the receiving hopper 42 through the connecting groove 35, thus recovering the remaining unsown seeds, avoiding waste, and saving production costs.

[0031] In summary, this effectively solves the problem that existing devices can only sow specific types of seeds, requiring different seeders to be used for different seeds, resulting in higher sowing costs. Furthermore, when changing seeds, it is inconvenient to collect the remaining seeds, which can even lead to waste.
