Description

Technical Field

[0001] This invention relates to the field of seeding technology, and in particular to a mobile directional seeder for plant seeds in mountainous areas. Background Technology

[0002] Seed planting refers to a series of steps taken to plant seeds in soil so that they can germinate and grow into plants. Seed planting in mountainous areas is a very beneficial activity that can promote ecological restoration, improve the environment, increase biodiversity, and provide beautiful natural landscapes. Seeders are usually used when sowing seeds.

[0003] For example, the corn planter disclosed in the patent with announcement number CN212344420U can sow seeds, but it does not have the function of fertilizing the sown seeds after sowing. Moreover, the current general fertilization method is just to spread the fertilizer, which results in uneven distribution of fertilizer and reduces the uniformity of seed growth. Therefore, there is an urgent need to design a mobile directional planter for mountainous areas. Summary of the Invention

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see the appendix Figure 1 -Appendix Figure 10A mobile directional seeder for plant seeds in mountainous areas includes a seeding plate 1, and further includes a fertilizer plate 3, a seeding component, and a fertilizer component. The fertilizer plate 3 is fixedly installed on the side of the seeding plate 1 by a fixing block. The seeding component is set on the seeding plate 1 and consists of a drive mechanism, a seed hopper 5, and a quantitative discharge mechanism. There are multiple quantitative discharge mechanisms that are evenly distributed in a straight line on the seeding plate 1. The quantitative discharge mechanism is used to quantitatively discharge seeds. The fertilizer component is set on the fertilizer plate 3 and consists of a fertilizer hopper 6, a moving mechanism, and a fertilizer application mechanism. There are multiple fertilizer application mechanisms that are evenly distributed in a straight line on the fertilizer plate 3. The fertilizer application mechanism is used to evenly fertilize the sown seeds.

[0036] The above-mentioned methods enable fertilization to be applied around the seeds after sowing, ensuring the uniformity of fertilization after sowing.

[0037] Please see the appendix Figure 1 -Appendix Figure 6 In a preferred embodiment, the quantitative discharging mechanism includes: a baffle plate 12, which is fixedly installed at the bottom of the seeding plate 1. The bottom of the baffle plate 12 has a through discharge port. A feeding plate 26 is rotatably installed inside the baffle plate 12. The outer arc surface of the feeding plate 26 has four storage troughs evenly distributed in a ring. The four storage troughs can be intermittently connected to the seed hopper 5 in sequence. A furrowing plate 10 and a soil covering plate 11 are vertically arranged on both sides of the baffle plate 12. The furrowing plate 10 and the soil covering plate 11 are both fixedly installed on the surface of the seeding plate 1. The furrowing plate 10 is located on the side of the seeding plate 1 away from the fertilizer plate 3, and the soil covering plate 11 is located on the side of the seeding plate 1 close to the fertilizer plate 3.

[0038] Specifically, as the feeding disc 26 rotates, the seeds inside the storage tank will fall through the discharge port into the groove of the grooving plate 10. This process can be repeated to continuously feed the seeds intermittently at equal intervals.

[0039] Please see the appendix Figure 1 -Appendix Figure 2 In a preferred embodiment, the driving mechanism includes: a rotating rod 13, there are multiple rotating rods 13, the multiple rotating rods 13 are spaced apart between adjacent feeding discs 26, the two ends of the corresponding rotating rod 13 are fixedly installed between the corresponding two feeding discs 26, the surface of the rotating rod 13 and the baffle 12 are rotatably arranged, a first motor 9 is installed at the bottom of the seeding plate 1, and the output shaft of the first motor 9 is installed at the center of the side of the corresponding feeding disc 26;

[0040] Furthermore, the first motor 9 drives multiple feeding discs 26 to rotate via the rotating rod 13, which is used to feed the seeds by rotating the feeding discs 26.

[0041] Please see the appendix Figure 1 -Appendix Figure 10In a preferred embodiment, the fertilization mechanism includes: a turntable 14, which is horizontally positioned at the bottom of the fertilization plate 3. A fertilization pipe 7 is fixedly installed at the bottom of the turntable 14. The fertilization pipe 7 can be Z-shaped or an inclined straight pipe. A V-shaped plate 33 is fixedly installed at the end of the fertilization pipe 7. An annular groove 35 is formed at the top of the turntable 14. A ratchet 36 is rotatably mounted on the inner wall of the annular groove 35. A pawl 37 is rotatably mounted at the bottom of the annular groove 35. A torsion spring is also installed between the pawl 37 and the annular groove 35. The end of the pawl 37 is located between the adjacent ratchet teeth of the ratchet 36. A limiting pin for limiting the pawl 37 is also installed at the bottom of the annular groove 35. When the turntable 14 rotates, the ratchet 36... The ratchet 37 will not be limited. It should be noted that when the slider 30 moves the turntable 14 horizontally, the ratchet 36 will move horizontally along with the turntable 14. The sliding plate 34 is mainly used to limit the ratchet 36, preventing it from rotating and ensuring the stability of the ratchet 36's limitation on the turntable 14. A through groove 8 is provided at the top of the fertilizer plate 3, and the slider 30 and sliding plate 34 are slidably installed inside the groove 8. The end of the sliding plate 34 is fixedly installed on the top of the ratchet 36. A hollow column 23 is fixedly installed on the top of the turntable 14. The surface of the hollow column 23 is rotatably mounted inside the slider 30. A flexible hose 24 is installed inside the hollow column 23. The top of the fertilizer pipe 7 and the top of the turntable 14... The hose 24 and fertilizer pipe 7 are rotatably connected, and the hose 24 is internally connected to the fertilizer hopper 6. A one-way bearing 22 is sleeved on the surface of the hollow column 23, and a second gear 21 is sleeved on the outer ring of the one-way bearing 22. A rack 25 is horizontally fixedly installed on the top of the fertilizer plate 3, and the rack 25 and the second gear 21 mesh with each other. A disc 17 is rotatably installed on the top of the fertilizer plate 3. A cam groove 18 is opened on the top of the disc 17. The cam groove 18 consists of a first holding section and a second holding section. The cam groove 18 mainly moves the insert plate 15, and the insert plate 15 has only two states: one is that the discharge port 28 is inside the fertilizer hopper 6, and the other is that the discharge port 28 is not inside the fertilizer hopper 6. Clearly, before the discharge port 28 moves out of the fertilizer hopper 6, the insert plate 15 has already blocked the fertilizer hopper 6, so that the fertilizer inside the fertilizer hopper 6 will not fall to the outside through the discharge port 28. A connecting rod 16 is vertically slidably installed inside the cam groove 18, and the insert plate 15 is horizontally fixedly installed at the top of the connecting rod 16, which is equivalent to the switch connecting the hose 24 and the fertilizer hopper 6. The top of the insert plate 15 has a through discharge port 28, and the surface of the insert plate 15 slides through the fertilizer hopper 6. An eccentric groove 31 is opened at the bottom of the disc 17. An L-shaped rod 32 is fixedly installed on the side of the slider 30. The top of the vertical side of the L-shaped rod 32 is slidably installed inside the eccentric groove 31. The L-shaped rod 32 is located inside the slide groove 8.

[0042] Preferably, when the slider 30 and its connecting parts move away from the seeding plate 1, the turntable 14 will rotate, while when the slider 30 moves towards the seeding plate 1, the turntable 14 will not rotate due to the restriction of the one-way bearing 22.

[0043] Please see the appendix Figure 5 -Appendix Figure 10 In a preferred embodiment, the moving mechanism includes: a first gear 20, there are multiple first gears 20, the multiple first gears 20 are rotatably mounted at the top center of multiple discs 17, a toothed belt 19 is sleeved on the surface of the multiple first gears 20, a second motor 27 is mounted on the top of the fertilizer plate 3, the output shaft of the second motor 27 is mounted at the top center of the corresponding first gear 20, and U-shaped plates 29 are slidably arranged on both sides of the toothed belt 19, and the vertical sides of the two U-shaped plates 29 are fixedly mounted on the top of the fertilizer plate 3;

[0044] Furthermore, the U-shaped plate 29 is used to limit the toothed belt 19 so that the first gear 20 in the middle can stably mesh with the toothed belt 19, ensuring that the multiple discs 17 rotate together and the fertilizer application is consistent.

[0045] Please see the appendix Figure 1 -Appendix Figure 10 In a preferred embodiment, a U-shaped connecting plate 2 is fixedly installed at both ends of the seeding plate 1. The U-shaped connecting plate 2 is used to connect with the tractor. Two symmetrically arranged tires 4 are installed at the bottom of the fertilizer plate 3. The seed hopper 5 is fixedly installed on the top of the seeding plate 1, and the fertilizer hopper 6 is fixedly installed on the top of the fertilizer plate 3.

[0046] The working principle of this invention is as follows: First, the device is installed on the tractor via the U-shaped connecting plate 2;

[0047] When in use, the device is placed in the field, and the fertilizer pipe 7 and the furrowing plate 10 are extended into the soil. As the tractor moves with the seeding plate 1 and the fertilizer plate 3, the furrowing plate 10 will open furrows in the soil to facilitate seed sowing. The first motor 9 and the second motor 27 (both servo motors) are started. The first motor 9 drives multiple feeding discs 26 to rotate through the rotating rod 13. When the storage trough and the seed hopper 5 are connected, the seeds in the seed hopper 5 will enter the corresponding storage trough. As the feeding disc 26 rotates, the seeds in the storage trough will fall through the discharge port into the furrows opened by the furrowing plate 10. The soil covering plate 11 will cover the furrows after sowing with soil, so that the soil covers the seeds and facilitates seed growth. This process can be repeated to continuously feed seeds intermittently at equal intervals.

[0048] The second motor 27 drives the first gear 20 and the toothed belt 19 to rotate (the U-shaped plate 29 is used to limit the toothed belt 19, ensuring that the first gear 20 can stably mesh with the toothed belt 19). The rotation of the first gear 20 drives the disc 17 to rotate, which in turn drives the cam groove 18 and the eccentric groove 31 to rotate. The rotation of the eccentric groove 31 drives the L-shaped rod 32 to move horizontally. The movement of the L-shaped rod 32 first causes it to move away from the seeding plate 1 (the fertilizer tube 7 is stationary relative to the seeds to be fertilized). The movement of the L-shaped rod 32 drives the slider 30 to move, which in turn drives the one-way bearing 22, the second gear 21, the hollow column 23, the turntable 14, and the fertilizer tube 7 to move. Due to the rack 25, the second gear 21 will also rotate (in the forward direction) as it moves. The rotation of the second gear 21 passes through... One-way bearing 22 drives hollow column 23 to rotate, and the rotation of hollow column 23 drives turntable 14 and fertilizer tube 7 to rotate, so that fertilizer tube 7 can rotate around the sown seeds to apply fertilizer. It should be noted that when slider 30 and second gear 21 move to their maximum stroke, the second gear 21 and turntable 14 have rotated one revolution (the vertical side of L-shaped rod 32 is located at the opposite end of the starting position of eccentric groove 31). When slider 30 and second gear 21 return, due to the setting of one-way bearing 22, the reverse rotation of second gear 21 will not drive hollow column 23 and turntable 14 to rotate. In addition, ratchet 35 will limit pawl 37 during the return stroke, further limiting turntable 14 and fertilizer tube 7, ensuring that fertilizer tube 7 will not be affected by soil resistance and turntable 14 will not rotate during the return stroke, thus ensuring the consistency of subsequent fertilization.

[0049] The rotation of the cam groove 18 causes the connecting rod 16 to move, and the movement of the connecting rod 16 causes the insert plate 15 to move. When the connecting rod 16 is in the first holding section (as shown in the attached figure), Figure 4 At this time, the connecting rod 16 is in the first holding section. It will connect the hose 24 and the fertilizer hopper 6 through the discharge port 28. The fertilizer inside the fertilizer hopper 6 can fall from the end of the fertilizer pipe 7 through the discharge port 28 and the hose 24. When the connecting rod 16 is in the second holding section, the connecting rod 16 will move. The movement of the connecting rod 16 will drive the insert plate 15 to move, so that the discharge port 28 can be moved out of the fertilizer hopper 6 (the hose 24 and the fertilizer hopper 6 are no longer connected). This avoids the situation where fertilizer is still being discharged from the fertilizer hopper 6 when the fertilizer pipe 7 returns, which would cause fertilizer waste.

[0050] In summary, by repeating this process, fertilizer can be continuously applied around the seeds after sowing, thereby improving the sowing effect of the equipment.

[0051] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
