Description

Technical Field

[0001] The present invention relates to the technical field of seed drills, in particular to a high-efficiency five-row sunflower seed drill. Background Art

[0002] As an important equipment in modern agriculture, the seeder has been widely used and rapidly developed in recent years. This type of seeder is usually connected to the rear suspension of the tractor and can directly and efficiently sow seeds after plowing the land. With the advancement of agricultural mechanization, the design of the seeder has been continuously optimized, and precise sowing technology and intelligent control systems have been adopted to improve sowing efficiency and accuracy. Modern seeders not only have multi-functional operations, but can also adjust sowing depth and density according to soil conditions and seed characteristics.

[0003] During the sowing process of sunflower seeds, general seeders are usually unable to accurately pick up individual seeds and cannot fully realize the feeding of individual seeds due to the differences in seed particles (different sizes and shapes) and interference from impurities. This will lead to differences in sowing uniformity, resulting in differences in planting density, which can easily lead to excessive seed density in some areas and sparse seeds in other areas. This situation not only affects the vegetation growth environment, but may also lead to waste of resources and loss of yield. Summary of the Invention

[0023] Third: the seeds enter the separation box and slide out from the bottom of the separation tube, thereby hitting the grain retaining plate, causing the seeds to jump into the separation box. During the jumping process of the seeds, the exhaust is exhausted through the exhaust pipe. During the suction process of the impurity removal pipe, the internal impurities of the separation box enter the interior of the impurity removal pipe through the protective cover, separating the seeds and impurities, thereby separating the impurities inside the seeds.

[0037] The invention discloses a high-efficiency five-row sunflower seeder mainly used in scenarios where it is difficult for a general seeder to perform single sowing and eliminate external impurity factors during sowing.

[0038] Reference Figure 1 — Figure 11 A high-efficiency five-row sunflower seeder includes a frame 1, a seed box 8 is provided on the top of the frame 1, a cover 7 is provided on the top of the seed box 8, a plurality of fuselages 2 are fixedly connected to one side of the frame 1, a traction frame 10 is provided on the other side of the frame 1, an air intake pipe 11 is provided at the input end of the air pump 12, an air pump 12 is provided on one side of the seed box 8, an exhaust pipe 6 is provided at the output end of the air pump 12, a transmission pipe 13 is provided at the bottom of the air pump 12, an air collection pipe 4 is provided at one end of the transmission pipe 13, and a plurality of impurity removal pipes 14 and an air suction pipe 16 are respectively provided on the lower surface of the air collection pipe 4;

[0039] A conveying mechanism is installed at the bottom of the seed box 8, which is used to convey seeds;

[0040] The bottom end of the impurity removal pipe 14 is equipped with a separation mechanism for separating seeds and impurities;

[0041] A sowing mechanism is installed at one end of the separation mechanism. The sowing mechanism includes a rotating wheel 25 rotatably connected to one end of the separation box 3. A plurality of sliding channels 37 are provided on one end surface of the rotating wheel 25. The sliding channels 37 are connected to the suction pipe 16 and generate negative pressure suction for adsorbing seeds.

[0042] A seeding shell 24 is provided outside the sliding path 37. When the sliding path 37 on the surface of the rotating wheel 25 rotates to the seeding shell 24 position, the negative pressure suction inside the sliding path 37 disappears, and the seeds will fall to the seeding shell 24 position for guided feeding.

[0043] The conveying mechanism includes a conveying motor 9 fixedly connected to the bottom of the seed box 8, one end of the output shaft of the conveying motor 9 is fixedly connected to a conveying threaded rod 17, a conveying tube 13 is provided on one side of the seed box 8, the conveying threaded rod 17 is inside the conveying tube 13, a seed tube 5 is provided at one end of the conveying tube 13, and a plurality of separation tubes 15 are provided at the bottom of the seed tube 5, and an electromagnetic valve is provided at one end of the separation tube 15 respectively, and a separation box 3 is provided at the bottom end of the separation tube 15.

[0044] The separation mechanism includes an inclined plate 27 fixedly connected to the bottom of the inner wall of the separation box 3, a grain retaining plate 28 is provided at the bottom edge of the separation tube 15, a protective cover 26 is fixedly connected to the top of the separation box 3, and a plurality of air vents are provided on the top of the separation box 3. The air vents are located at the bottom of the protective cover 26, and the bottom end of the impurity removal tube 14 is connected to the interior of the protective cover 26.

[0045] In this embodiment, the traction frame 10 is connected to the suspension of the tractor, the cover 7 is removed and the seeds are loaded into the seed box 8, the tractor drives the frame 1 forward, multiple plows 19 open ditches on the soil on the ground, and the transmission motor 9 is started to drive the transmission threaded rod 17 to rotate, and the seeds inside the seed box 8 are transmitted to the inside of the seed tube 5 and the separation tube 15.

[0046] Furthermore, according to the required sowing width, a corresponding number of solenoid valves are selected, and the corresponding solenoid valves are opened to guide the seeds inside the separation tube 15 into the interior of the separation box 3, thereby controlling the sowing width and sowing position.

[0047] In this embodiment, the seeds enter the interior of the separation box 3, and the seeds slide out from the bottom of the separation tube 15, thereby hitting the grain blocking plate 28, causing the seeds to jump into the interior of the separation box 3. During the jumping process of the seeds, the dust and impurities attached to the surface of the seeds are separated. Since the seed feeding speed is slow, it is prevented that a large amount of seeds accumulate in a short time to block the discharge port of the separation tube 15. The air pump 12 is started and air is sucked through the air inlet pipe 11, the air collecting pipe 4, the air suction pipe 16 and the impurity removal pipe 14, and exhausted through the exhaust pipe 6. During the air suction process of the impurity removal pipe 14, the internal impurities of the separation box 3 enter the interior of the impurity removal pipe 14 through the protective cover 26, so that the seeds and impurities are separated.

[0048] Reference Figure 3 、 Figure 5 、 Figure 7 and Figure 8 In a preferred embodiment, the sowing mechanism includes a rotating wheel 25 rotatably connected to one end of the separation box 3, and a plurality of sliding channels 37 are provided on the surface of one end of the rotating wheel 25. The interior of the sliding channel 37 is slidably connected to a sliding cylinder 38, and the interior of the sliding cylinder 38 is provided with an air channel 47. An air ring 36 is provided at one end of the sliding cylinder 38, and one end of the sliding cylinder 38 is fixedly connected to a mounting shell 50 near the position of the air ring 36. The interior of the mounting shell 50 is slidably connected to a sliding rod 46, and the bottom end of the sliding rod 46 is sleeved with a spring 45.

[0049] Specifically, a sealing block 49 is fixedly connected to the bottom of the sliding rod 46, a circular slide rail 51 is provided on one side of the air ring 36, a hose 35 is connected to the top edge of the air ring 36, and a driving shaft 33 is connected to the other end of the rotating wheel 25. An air cavity 34 is provided inside the driving shaft 33, and the bottom end of the hose 35 is connected to the air cavity 34. The bottom of the separation box 3 is fixedly connected to the first fixed seat 29, one end of the first fixed seat 29 is fixedly connected to the second fixed seat 31, and the second fixed seat 31 is rotatably connected to one end of the driving shaft 33. A driven wheel 44 is provided at one end of the driving shaft 33, and a sowing motor 40 is provided at the bottom of the second fixed seat 31, and a driving wheel is provided at one end of the output shaft of the sowing motor 40.

[0050] Specifically, a belt 43 is provided between the driving wheel and the driven wheel 44, the top of the fuselage 2 is fixedly connected to the extrusion plate 30, the interior of the fuselage 2 is fixedly connected to the plow 19, an inoculation shell 23 is fixedly connected to the inner wall of one side of the plow 19, one side of the inoculation shell 23 is fixed to the seeding shell 24, and a guide tube 20 is inserted into the bottom of the inoculation shell 23.

[0051] In this embodiment, the seeds slide downward to the edge of the bottom of the rotating wheel 25 through the guiding effect of the inclined plate 27, and the sowing motor 40 is started to drive the driving wheel and the driven wheel 44 to rotate, thereby driving the driving shaft 33 and the rotating wheel 25 to rotate. The seeds will be located at the sliding path 37 at one end of the rotating wheel 25. As the suction pipe 16 draws air outward and generates negative pressure suction through the suction pipe 16, the air cavity 34, the hose 35 and the air channel 47, the sunflower seeds are adsorbed at the end of the sliding path 37. The diameter of the sliding path 37 needs to be slightly smaller than the minimum cross-sectional size of the sunflower seeds to ensure single-seed adsorption. Sunflower seeds have an irregular shape (length of about 8-15 mm, width of about 4-8 mm), and the diameter of the sliding path 37 is generally controlled to be between 5-10 mm.

[0052] Furthermore, the position of a sliding channel 37 can only hold one seed. When the sliding rod 46 passes the position of the extrusion plate 30, the extrusion plate 30 squeezes the sliding rod 46 to make it shrink inward, thereby squeezing the spring 45, driving the bottom sealing block 49 to block the air channel between the air channel 47 and the air ring 36, so that the internal negative pressure suction of the sliding channel 37 disappears, making it easier to discharge the seeds.

[0053] It needs to be explained that, Figure 8 As shown, the shape of the sealing block 49 is an "L" shape rotated ninety degrees clockwise. During the downward movement of the sealing block 49, the left end of the sealing block 49 will first block the airway 47. As the sealing block 49 continues to move downward, the air inside the airway 47 will be compressed, causing the air inside the airway 47 to be ejected from the position of the sliding channel 37. At this time, the single seed at the position of the sliding channel 37 will be squeezed out by the airflow, thereby improving the feeding effect, and will fall into the interior of the seed-digging shell 24, and enter the interior of the inoculation shell 23 through the seed-digging shell 24. The seeds enter the interior of the ditch opened by the plow 19 through the inoculation shell 23 and the guide tube 20. The density of seed sowing is controlled by controlling the movement speed of the tractor and the rotation speed of the sowing motor 40, thereby achieving the effect of accurately sowing seeds.

[0054] Further, such as Figure 9 and Figure 10 As shown, a circular connecting groove 48 is provided on one end surface of the rotating wheel 25, and the circular connecting groove 48 connects the edges of multiple sliding channels 37 together. The seed-digging shell 24 includes a narrow limiting portion 2401 and a wide expansion portion 2402. The limiting portion 2401 of the seed-digging shell 24 slides inside the circular connecting groove 48.

[0055] In this embodiment, as the rotating wheel 25 rotates, the limiting portion 2401 of the seed-picking shell 24 will always be located at the circular connecting groove 48 until the sliding path 37 for adsorbing the sunflower seeds passes through the limiting portion 2401. The limiting portion 2401 will exert an upward external force on the seeds, causing them to slide downward along the expansion portion 2402 of the seed-picking shell 24. At the same time, the limiting portion 2401 can also remove small-sized seeds or impurities that may be located inside the sliding path 37, further ensuring the feeding effect.

[0056] Reference Figure 1 、 Figure 2 、 Figure 6 and Figure 7 、 Figure 11 In a preferred embodiment, an adjustment mechanism is installed at one end of the sowing mechanism, and the adjustment mechanism includes a fixed rail 52 fixedly connected to the bottom of the circular slide rail 51, and a moving block 32 is fixedly connected to the bottom of the fixed rail 52, and sliding grooves are respectively provided on the outer surface of the sliding cylinder 38 near the sliding rod 46.

[0057] The mounting shell 50 and the sliding rod 46 move in the sliding groove, one end of the moving block 32 is threadedly connected to the adjusting threaded rod 42, one end of the adjusting threaded rod 42 is fixedly connected to the adjusting motor 41, the adjusting motor 41 is fixedly connected to one end of the second fixed seat 31, and the other side of the moving block 32 is slidably connected to the guide rod 39.

[0058] In this embodiment, the adjusting motor 41 can be started to drive the adjusting threaded rod 42 to rotate, thereby driving the moving block 32 and the air ring 36 to move backward, and the air ring 36 can be used to drive multiple sliding cylinders 38 to be pulled out and disengaged from the interior of the sliding channel 37, so as to facilitate subsequent internal maintenance of the sliding cylinder 38 and avoid blockage of the internal passage and maintenance difficulties.

[0059] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In a preferred embodiment, an auxiliary mechanism is installed at the bottom of the fuselage 2, and the auxiliary mechanism includes two first mounting rods fixedly connected to the bottom of one end of the fuselage 2, and the bottom ends of the first mounting rods are rotatably connected to the toggle wheels 18, and the bottom of the other end of the fuselage 2 is fixedly connected to two second mounting rods.

[0060] The bottom end of the second mounting rod is rotatably connected to a leveling wheel 21, and the other end of the fuselage 2 is fixedly connected to a fixing plate. The bottom of the fixing plate is fixedly connected to two third mounting rods, and the bottom ends of the third mounting rods are rotatably connected to push wheels 22 respectively.

[0061] In this embodiment, when sowing seeds, the body 2 drives the toggle wheel 18 to rotate, and the toggle wheel 18 pushes impurities, dead grass and other debris in front to both sides. The plow 19 opens a ditch on the ground. After the seeds enter the ditch, the leveling wheel 21 pushes the soil on both sides of the ditch back into the ditch, and the remaining soil is leveled by the leveling wheel 22, which has the effect of assisting sowing and leveling the soil.

[0062] Working principle: When in use, connect the traction frame 10 to the suspension of the tractor, remove the cover 7 and put the seeds into the seed box 8. The tractor drives the frame 1 forward, and multiple rakes 19 dig ditches on the ground soil. Start the transmission motor 9 to drive the transmission threaded rod 17 to rotate, and the seeds in the seed box 8 are transmitted to the inside of the seed tube 5 and the separation tube 15. According to the required sowing width, select the corresponding number of solenoid valves, open the corresponding solenoid valves to guide the seeds in the separation tube 15 into the separation box 3, thereby controlling the sowing width and sowing position;

[0063] Then as Figure 5As shown, the seeds slide out from the bottom of the separation tube 15, thereby hitting the grain retaining plate 28, causing the seeds to jump. During the seed jumping process, the dust and impurities attached to the surface of the seeds will be separated due to the vibration force. During this process, the rotation speed of the conveying threaded rod 17 is slow, which prevents a large amount of seeds from accumulating in a short period of time and blocking the discharge port of the separation tube 15. Then, the air pump 12 is started and air is sucked through the air inlet pipe 11, the air collecting pipe 4, the air suction pipe 16 and the impurity removal pipe 14, and exhausted through the exhaust pipe 6. During the air suction process of the impurity removal pipe 14, the internal impurities of the separation box 3 enter the impurity removal pipe 14 through the protective cover 26. The seeds are separated from impurities by the guiding effect of the oblique plate 27, and the seeds slide downward to the edge of the bottom of the rotating wheel 25. The sowing motor 40 is started to drive the driving wheel, the belt 43 and the driven wheel 44 to rotate, thereby driving the driving shaft 33 and the rotating wheel 25 to rotate. The seeds will come into contact with the sliding path 37 at one end of the rotating wheel 25. As the suction pipe 16 sucks air outward, negative pressure suction is generated through the suction pipe 16, the air cavity 34, the hose 35 and the air channel 47, which adsorbs the seeds located at the position of the sliding path 37. At this time, one position of the sliding path 37 can only retain one seed;

[0064] Then as Figure 5 and Figure 8 As shown, when the sliding rod 46 passes the position of the squeezing plate 30, the squeezing plate 30 squeezes the sliding rod 46 to make it contract inward, thereby squeezing the spring 45, driving the bottom sealing block 49 to block the air passage between the air passage 47 and the air ring 36, so that the internal negative pressure suction of the sliding passage 37 disappears. At this time, the sealing block 49 continues to move downward and compresses the air inside the air passage 47, so that the air inside the air passage 47 is ejected from the opening position of the sliding passage 37. At this time, the single seed at the position of the sliding passage 37 is driven by the ejected air and fully falls into the interior of the seed-pulling shell 24, and enters the interior of the inoculation shell 23 through the seed-pulling shell 24;

[0065] Finally, the seeds pass through the inoculation shell 23 and the guide tube 20 and enter the ditch opened by the plow 19. The density of seed sowing is controlled by controlling the movement speed of the tractor and the rotation speed of the sowing motor 40, which achieves the effect of precise seed sowing. When sowing seeds, the fuselage 2 drives the toggle wheel 18 to rotate, and the toggle wheel 18 pushes the impurities and dead grass in front to both sides. The plow 19 opens a ditch on the ground. After the seeds enter the ditch, the leveling wheel 21 pushes the soil on both sides of the ditch back into the ditch, and the remaining soil is flattened by the leveling wheel 22, which has the effect of assisting sowing and leveling the soil.

[0066] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
