Description

Technical Field

[0001] The present invention relates to the technical field of seeders, and specifically to an integrated self-fertilizing corn seeder and its usage method. Background Art

[0002] The planting area and output of corn in China have both maintained stable growth. From the perspective of production area distribution, among the 31 provinces (autonomous regions, municipalities directly under the Central Government) in the country, except for Hainan, large-scale production of corn is involved, and the planting area and output scale of Heilongjiang Province rank first in the country.

[0003] When planting corn on a large scale, manual operation can no longer meet the production needs, and large-scale planting has been replaced by mechanization. Among them, a corn seeder is a planting machine that uses corn seeds as the sowing object. When the existing corn seeder sows corn into the land, it often cannot fertilize the seeds. If additional fertilization is required, a fertilizer applicator needs to be used for fertilization operations. For this reason, we propose an integrated self-fertilizing corn seeder and its usage method. Summary of the Invention

The bottoms of the two ends of the strip-shaped seat are respectively vertically connected to a first guide shaft. The middle parts of the strip-shaped seat are respectively vertically connected to a first hydraulic cylinder. The first hydraulic cylinders are respectively fixed to the frame, and the first guide shafts are respectively movably connected to the frame. Among them, the first hoppers are installed on the top of the first installation beam, and the second hoppers are installed on the top of the second installation beam.

[0008] Preferably, the sowing mechanism includes a circular outer shell connected to the lower ends of the respective connecting pipes. The circular outer shells are respectively connected to the first mounting beam through mounting frames. A cylindrical seat is coaxially arranged inside each circular outer shell. The cylindrical seat is in clearance fit with the circular outer shell. A number of grooves parallel to its axis are arranged at intervals on the surface of the cylindrical seat. A downwardly inclined blanking chute is connected to the bottom of the circular outer shell. Among them, the discharge port is located at the side of the blanking chute. The cylindrical seats are coaxially mounted on the connecting shaft. The connecting shaft is connected to the center of each circular outer shell. One end of the connecting shaft is connected to the driving motor, and the driving motor is mounted on the machine frame.

[0009] Preferably, a ditching device is further provided between the two strip-shaped seats. The ditching device includes a fourth mounting beam installed between the two strip-shaped seats. A second connecting beam is arranged in parallel below the fourth mounting beam. Ditching shovels corresponding to the number of blanking chutes are installed below the second connecting beam. The ditching shovels are respectively located in front of the blanking chutes. At both ends of the top of the second connecting beam, third guiding shafts are vertically provided respectively. In the middle of the top of the second connecting beam, a third hydraulic cylinder is vertically installed. The top of the third hydraulic cylinder is connected to the fourth mounting beam, and the top of the third guiding shaft is movably connected to the fourth mounting beam.

[0010] Preferably, at one end of the top of the machine frame away from the hanging rack, a third mounting beam is installed.

Detailed implementation mode

[0028] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0029] Refer to Figures 1 to 7 , the present invention provides a technical solution: an integrated self-fertilizing corn planter, including a frame 1, support seats 4 are installed at both bottoms of the frame 1, traveling wheels 5 are respectively provided at the bottoms of the support seats 4, and a hanging frame connected to agricultural machinery is provided at one end of the frame 1. As Figure 1 shown, the hanging frame includes a U-shaped frame body 12 connected to the middle of one side of the frame 1, the side of the U-shaped frame body 12 away from the frame 1 is connected to a connecting seat 21, and a hanging hole is provided at the end of the connecting seat 21. During use, the frame 1 is towed, the connecting seat 21 is placed in the hook at the tail of the agricultural machine, and then connected by a bolt. At this time, driving the agricultural machine can drive the frame 1 to travel.

[0030] A lifting mechanism is provided inside the frame 1. As Figure 5 shown, the lifting mechanism includes a first mounting beam 11 and a second mounting beam 13 that are parallel to each other. The second mounting beam 13 is located inside the frame 1 on the side close to the U-shaped frame body 12;

[0031] Both ends of the first mounting beam 11 and the second mounting beam 13 are respectively connected to the strip seat 2. The bottoms of both ends of the strip seat 2 are respectively vertically connected with a first guiding shaft 3. The middle parts of the strip seat 2 are respectively vertically connected with a first hydraulic cylinder 6. The first hydraulic cylinders 6 are respectively fixed to the frame 1, and the first guiding shafts 3 are respectively movably connected to the frame 1. The two first hydraulic cylinders 6 are lifted and lowered synchronously. Therefore, when the first hydraulic cylinders 6 are lifted and lowered, the first mounting beam 11 and the second mounting beam 13 can be driven to move up and down;

[0032] At the top of the lifting mechanism, there are multiple (two) first hoppers 9 arranged in a straight line. The bottom of each first hopper 9 is connected to the sowing mechanism through a connecting pipe 23. On one side of each first hopper 9, there is a second hopper 10, and the second hoppers 10 are also arranged in a straight line. In the actual application process, specifically, the first hoppers 9 are installed on the top of the first installation beam 11, and the second hoppers 10 are installed on the top of the second installation beam 13;

[0033] As Figure 5 shown, the bottom of each second hopper 10 is respectively connected to a spiral conveyor cylinder 27. The spiral conveyor cylinders 27 extend towards the sowing mechanism, and the discharge ports 26 at the bottom of the spiral conveyor cylinders 27 are respectively located at the sides of each sowing mechanism.

[0034] Specifically, strip-shaped boxes 19 are respectively installed on the tops of the first hoppers 9 and the second hoppers 10. This can not only increase the storage space but also connect each hopper into a whole. In this way, when pouring fertilizers and corn seeds, the fertilizers and corn seeds can flow quickly into each hopper;

[0035] During the process of the agricultural machine driving the frame 1 to move, the corn seeds in the first hopper 9 continuously fall to the ground from the sowing mechanism. At the same time, the spiral conveyor cylinder 27 also continuously conveys the fertilizers in the second hopper 10 downward. As Figure 4 shown, the fertilizers just fall above the seeds after coming out of the discharge port 26, so that the seeds can be covered with fertilizers while sowing.

[0036] The following is a detailed introduction to the seeder:

[0037] As Figure 5 shown, the sowing mechanism includes a circular outer shell 14 connected to the lower ends of each connecting pipe 23. The circular outer shells 14 are respectively connected to the first installation beam 11 through mounting brackets 15. The circular outer shells 14 are located below the first installation beam 11. The spiral conveyor cylinders 27 pass below the first installation beam 11, and the spiral conveyor cylinders 27 are connected to the first installation beam 11 through connecting brackets 34;

[0038] Inside the circular outer shell 14, there is a cylindrical seat 33 coaxially arranged. There is a clearance fit between the cylindrical seat 33 and the circular outer shell 14, that is, the clearance size between the two will not allow corn to enter. There are several grooves 32 parallel to its axis spaced on the surface of the cylindrical seat 33. At the bottom of the circular outer shell 14, there is a downwardly inclined blanking chute 25. As Figure 5 shown, the discharge port 26 is arranged at the side of the blanking chute 25. The cylindrical seats 33 are all coaxially installed on the connecting shaft 22. The connecting shaft 22 is connected to the center of each circular outer shell 14. One end of the connecting shaft 22 is connected to the driving motor 20, and the driving motor 20 is installed on the frame 1;

[0039] When the drive motor 20 rotates, it can drive the connecting shaft 22 to rotate, and the connecting shaft 22 can drive each cylindrical seat 33 to rotate. When the cylindrical seat 33 rotates, the grooves 32 on its surface pass below the connecting pipe 23 in sequence, and the size of the groove 32 can only accommodate 3 - 5 seeds. Because during corn sowing, this method can ensure the emergence rate.

[0040] Furthermore, during sowing, the corn needs to be buried in the soil, so a ditching device is also provided between the two strip-shaped seats 2;

[0041] As Figure 5 shown, the ditching device includes a fourth installation beam 30 installed between the two strip-shaped seats 2. A second connecting beam 24 is arranged in parallel below the fourth installation beam 30. Below the second connecting beam 24, ditching shovels 28 corresponding to the number of the blanking grooves 25 are installed, and the ditching shovels 28 are respectively located in front of the blanking grooves 25;

[0042] At both ends of the top of the second connecting beam 24, third guiding shafts 29 are respectively vertically provided. In the middle of the top of the second connecting beam 24, a third hydraulic cylinder 31 is vertically installed. The top of the third hydraulic cylinder 31 is connected to the fourth installation beam 30, and the top of the third guiding shaft 29 is movably connected to the fourth installation beam 30. The ditching shovels 28 need to penetrate into the ground between 3 and 7 centimeters, so controlling the third hydraulic cylinder 31 to drive the ditching shovels 28 to insert into the ground once is enough. When the frame is moving, the ditching shovels 28 can dig a planting ditch in front of each blanking groove 25, and the corn seeds fall into the planting ditch at intervals;

[0043] The corn seeds sown in the planting ditch need to be covered with soil, so a soil covering mechanism is also provided at the tail of the frame. As Figure 5 shown, at one end of the top of the frame 1 far away from the hanging rack, a third installation beam 7 is installed. A first connecting beam 17 is arranged in parallel below the third installation beam 7. Below the first connecting beam 17, soil covering shovels 16 corresponding to the number of the blanking grooves 25 are installed, and the soil covering shovels 16 are respectively located behind the blanking grooves 25;

[0044] At both ends of the top of the first connecting beam 17, second guiding shafts 8 are respectively vertically provided. In the middle of the top surface of the first connecting beam 17, a second hydraulic cylinder 18 is vertically connected. The top of the second hydraulic cylinder 18 is connected to the third installation beam 7, and the top of the second guiding shaft 8 is movably connected to the first connecting beam 17. Controlling the soil covering shovels 16 to insert into the ground, actually the insertion depth of the soil covering shovels 16 can be slightly greater than the insertion depth of the ditching shovels 28 into the ground, so that the soil can be better turned over into the planting ditch to cover the corn seeds.

[0045] Furthermore, the present invention also proposes a usage method of the self-fertilizing integrated corn seeder, including the following steps:

[0046] Step 1: Connect the frame 1 to the agricultural machinery through the hanging rack;

[0047] Step 2: Place the fertilizer in the strip box 19 above the second hopper 10 to allow the fertilizer to flow into each spiral conveyor cylinder 27. Place the corn seeds in the strip box 19 above the first hopper 9 to allow the corn seeds to flow into each connecting pipe 23.

[0048] Step 3: Control the third hydraulic cylinder 31 to descend, so that the ditching shovel 28 inserts into the ground. Control the second hydraulic cylinder 18 to descend, so that the soil covering shovel 16 inserts into the ground.

[0049] Step 4: Drive the agricultural machine forward. At the same time, turn on the drive motor 20 and the spiral conveyor cylinder 27. The drive motor 20 drives the seeds to fall from each material dropping groove 25 into the ditch dug by the ditching shovel 28. The spiral conveyor cylinder 27 continuously transports the fertilizer onto the corn seeds. Finally, the soil covering shovel 16 turns the soil over to cover the corn seeds.

[0050] In summary, the set strip box 19 has a large storage capacity. A sealing cover can be provided on the top of the strip box 19 and covered during use. Therefore, the seeds and fertilizer in the strip box 19 can be used for long-term large-area planting.

[0051] Moreover, both the material dropping groove 25 and the discharge port 26 can be lifted and lowered. When not in use, they can be driven to a high position by controlling the first hydraulic cylinder 6 to avoid touching the ground during driving.

[0052] Both the soil covering shovel 16 and the ditching shovel 28 can also be lifted and lowered. When not in use, they can be driven to a high position by controlling the third hydraulic cylinder 31 and the second hydraulic cylinder 18 to avoid touching the ground during driving.

[0053] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
