Description

Technical Field

[0001] The invention relates to the technical field of sowing devices, and in particular to a directional sowing device for pinellia ternata. Background Art

[0002] Pinellia, also known as Diwen and Shoutian, belongs to the Araceae, Araceae and Pinellia genus. It has the effects of drying dampness and resolving phlegm, relieving adverse reactions and stopping vomiting, and suppressing cough and anti-ulcer. Pinellia prefers a mild and humid environment with semi-shade and semi-sun. It is cold-resistant but not drought-resistant, and avoids exposure to the scorching sun. It has strict requirements on soil and is suitable for growing in loose, fertile sandy loam with strong water and fertilizer retention capacity. With the rapid development of Chinese medicinal materials industry, the planting area and yield of Pinellia are increasing. Traditional sowing methods of Pinellia mostly rely on manual sowing or simple mechanical sowing.

[0003] However, the prior art has the following problems:

[0004] 1. In the prior art, when sowing Pinellia ternata, most of the seeds are scattered, so that the number of seeds sown on the land in different areas may not be uniform, and it is difficult to control the spacing and number of seeds. In some areas, the seeds are too dense, resulting in a small growth space for seedlings, and they compete with each other for nutrients, water and light, resulting in weak and thin seedlings, affecting the overall growth and yield. In some areas, the seeds are sparse, resulting in a waste of land resources and reducing the yield per unit area.

[0005] 2. Since the particle sizes of Pinellia seeds vary, if they are sown uniformly, different seedlings may grow differently in the same area. It will be difficult to determine a uniform standard when fertilizing, irrigating, and controlling pests and diseases. This may eventually lead to inconsistent maturity times for Pinellia, thus affecting harvesting. Summary of the invention

After the seesaw 39 is tilted, an opening is formed at the seesaw 39, and the spoon ring 35 can enter the inner slide 38 through the sowing slide 36 without affecting the movement trajectory of the spoon ring 35. A sealing structure is formed between the multiple inner slides 38 and the left bottom of the trough 31, so that the spoon ring 35 can enter the trough 31 from the lowest point inside the trough 31, ensuring that the spoon ring 35 can contact the seeds. Through the arrangement of the sowing assembly 3, when the multiple turntables 34 rotate, the seeds are transported in rows to the multiple sowing slides 36 through the multiple spoon rings 35, so that the seeds slide into the multiple fixed tubes 37 for subsequent sowing, thereby achieving the effect of sowing single seeds in rows according to the direction of travel, and the sowing efficiency is high.By setting the seesaw 39, the seesaw 39 can move the seeds sliding in the sowing slide 36 when it is tilted, promoting the sliding process of the seeds. The seesaw 39 ensures the sealing of the sowing slide 36 without affecting the movement trajectory of the spoon ring 35, preventing smaller seeds from sliding into the inner slide 38.

[0038] For further information, see Figure 4 - Figure 5 , a seed selection component 4 is used to screen the seed particle size; the seed selection component 4 includes an outer screening bucket 41, the outer screening bucket 41 is hinged inside the material trough 31, the inner wall of the outer screening bucket 41 is slidably connected with the inner screening bucket 42, a lever is provided in the material trough 31, the bottom of the outer screening bucket 41 is overlapped on the lever, the inner wall of the material trough 31 is hinged with two prying rods 44, the bottom of the outer screening bucket 41 is connected to two convex rods 45, the left end of the prying rod 44 is provided with an arc surface, and the multiple spoon rings 35 on the front turntable 34 are in contact with the left end of the prying rod 44 in the front during the movement. The multiple spoon rings 35 on the rearmost turntable 34 are in sliding contact with the curved surface of the left end of the pry bar 44 at the rear during movement. The right ends of the two pry bars 44 are in contact with the two protruding rods 45 respectively during movement. A baffle is provided at the position where the pry bars 44 are located to prevent the seeds from moving to the bottom of the pry bars 44 and being pressed. When the multiple spoon rings 35 are in motion, they use the lever principle to drive the outer sieve bucket 41 to shake up and down continuously through the two pry bars 44. When the outer sieve bucket 41 shakes, it promotes the seeds in the inner sieve bucket 42 to be continuously screened, so that the smaller seeds can be The seeds fall into the trough 31 through the sieve holes; the outer sieve bucket 41 and the inner sieve bucket 42 are respectively provided with a plurality of sieve holes, and the plurality of sieve holes of the inner sieve bucket 42 are of the same size and position as the plurality of sieve holes of the outer sieve bucket 41; the inner wall of the outer sieve bucket 41 is rotatably connected with an adjusting screw 43, and the adjusting screw 43 is threadedly connected to the inner wall of the inner sieve bucket 42; when the adjusting screw 43 is rotated, the adjusting screw 43 drives the inner sieve bucket 42 to move through the threaded connection relationship between the adjusting screw 43 and the inner sieve bucket 42, so that the plurality of sieve holes of the inner sieve bucket 42 are misaligned with the plurality of sieve holes of the outer sieve bucket 41, so that the sieve The effective passing area of ​​the hole is reduced, so that the inner sieve bucket 42 can cooperate with the outer sieve bucket 41 to adjust the size of the screening particle size; through the setting of the seed selection component 4, the outer sieve bucket 41 and the inner sieve bucket 42 can cooperate to screen the seeds, so that the particle size of the seeds sown in the same batch is relatively uniform, and the staff can also adjust the screening particle size by adjusting the screw 43, divide the seeds of different particle sizes into multiple levels and plant them in corresponding areas, so that the seed size in the same area is uniform, and the subsequent growth of Pinellia ternata is also relatively uniform, which is convenient for subsequent care and picking.

[0039] Further, see Figure 6 - Fig.10, a punching assembly 5 is used to punch seed holes; the punching assembly 5 includes a movable frame 51, which is slidably connected to the frame 1, and the front and rear outer walls of the base 2 are respectively slidably connected with sliders 52, and the front and rear outer walls of the base 2 are respectively rotatably connected with gears 54, and the outer wall of the rotating shaft 33 is connected with two gear rings 53, and the two gear rings 53 are respectively meshed with two gears 54, and a cam 55 is connected to the gear 54. A slide groove is provided on the slide 52, and the ends of the two cams 55 are respectively slidably connected with the slide grooves on the two slides 52 through bearings. When the cam 55 rotates, the slide 52 is driven to reciprocate up and down through the cooperation of the bearing and the slide groove. The two slides 52 are respectively connected to the movable frame 51 through a bracket, and a plurality of telescopic tubes 56 are connected to the movable frame 51 through a bracket. The outer walls of the multiple telescopic tubes 56 are slidably connected to the inner walls of the multiple fixed tubes 37 respectively. When the two sliders 52 move back and forth up and down, the movable frame 51 drives the multiple telescopic tubes 56 to move back and forth up and down through the bracket. The movable frame 51 drives the multiple telescopic tubes 56 to move back and forth up and down through the bracket. The multiple telescopic tubes 56 reciprocate up and down in the multiple fixed tubes 37 respectively, and the seeds in the fixed tubes 37 fall into the telescopic tubes 56. The outer surface of the bottom end of the telescopic tube 56 is connected to four mounting seats 511, and the four mounting seats 511 are respectively hinged with cone head pieces 512. The four cone head pieces 512 are arranged in a circular array. The four cone head pieces 512 form a conical whole, and the four cone head pieces 512 are closed to each other when they are not in contact with the ground. The outer wall of the telescopic tube 56 is slidably connected to the mounting seats 511. The mounting ring 58 has two sliding shafts 59 connected to the top of the mounting ring 58, and two fixing rods 57 are connected to the frame 1. The fixing rods 57 are provided with a plurality of round holes. The plurality of round holes of the two fixing rods 57 are respectively slidably connected with the outer walls of the plurality of sliding shafts 59. The top of the sliding shaft 59 is provided with an end head, and the end head of the sliding shaft 59 abuts against the fixing rod 57 during movement. The outer wall of the mounting ring 58 is connected with four connecting arms 510, and connecting rods 513 are respectively hinged between the four connecting arms 510 and the four cone head pieces 512. When the four cone head pieces 512 punch out seed holes, the ends of the tops of the two sliding shafts 59 abut against the two fixing rods 57, so that the two sliding shafts 59 drive the mounting ring 58 to stop moving downward, so that the mounting ring 58 pulls the four connecting rods 513 through the four connecting arms 510. 13. When the connecting rod 513 is pulled, the cone head piece 512 is driven to flip outward through the lever principle, so that the four cone head pieces 512 flip outward at the same time, and the seeds falling through the telescopic tube 56 fall on the inner side of the four cone head pieces 512. When the four cone head pieces 512 are opened, the seeds fall into the seed holes; through the setting of the punching component 5, the multiple telescopic tubes 56 and the multiple fixed tubes 37 form a sealed slideway for the seeds through cooperation, ensuring that the seeds can accurately slide to the sowing position, and the four cone head pieces 512 at the bottom of the fixed tube 37 punch out the seed holes through cooperation, and then the four cone head pieces 512 automatically open to place the seeds inside them in the seed holes, so that the hole punching and sowing are carried out almost simultaneously, reducing the equipment investment cost, the punched seed holes are smaller, and the subsequent backfilling is more convenient.

[0040] For further information, see Fig.11 - Fig.12 The fixed tube 37 is also provided with an anti-blocking portion 6, which includes an inner ring 61, which is rotatably connected to the inner wall of the fixed tube 37, and a plurality of scrapers 62 are installed on the inner ring 61, and the scrapers 62 are in contact with the inner walls of the fixed tube 37 and the telescopic tube 56. The inner ring 61 is connected with a shifting shaft 63, and a slot plate 64 is slidably connected to the outer wall of the fixed tube 37. The shifting shaft 63 penetrates the fixed tube 37, and the shifting shaft 63 is slidably connected to the fixed tube 37. The slot plate 64 is provided with an arc groove, and the shifting shaft 63 is slidably connected to the arc groove of the slot plate 64. A connecting rod 65 is connected between the slot plate 64 and the outer wall of the telescopic tube 56; when the slot plate 64 reciprocates, it passes through the arc groove. The shaped groove drives the pull shaft 63 to slide back and forth along the through connection between it and the fixed tube 37, so that the pull shaft 63 drives the inner ring 61 to reciprocate in the fixed tube 37. When the inner ring 61 rotates, it drives multiple scrapers 62 to rotate synchronously. When the multiple scrapers 62 rotate, they can scrape the inner walls of the fixed tube 37 and the telescopic tube 56, thereby preventing the inner walls from being blocked. Through the setting of the anti-blocking part 6, the multiple scrapers 62 continuously scrape the inner walls of the fixed tube 37 and the telescopic tube 56 by reciprocating rotation, thereby preventing some seeds with larger particle sizes from getting stuck on the inner walls of the fixed tube 37 or the telescopic tube 56 when falling, thereby causing pipeline blockage.

[0041] With the above structure, the working principle of this case is that the frame 1 can be towed on a tractor, and the frame 1 is moved by the tractor. When the frame 1 moves, it drives the base 2 to move synchronously. After the motor 32 is started, the motor 32 drives the rotating shaft 33 to rotate, the rotating shaft 33 drives multiple rotating disks 34 to rotate, and the rotating disks 34 drive multiple spoon rings 35 to rotate. The spoon rings 35 revolve around the rotating shaft 33 in the sowing slide 36, the inner slide 38 and the material trough 31. The multiple spoon rings 35 on the multiple rotating disks 34 are regarded as multiple rows. When each row of spoon rings 35 moves from the multiple inner slides 38 to the material trough 31, the multiple spoon rings 35 contact the seeds in the material trough 31. The spoon rings 35 are provided with conical holes. After one seed slides into the conical hole of the spoon ring 35, , the spoon ring 35 drives the seed to continue to move, and the conical hole of the spoon ring 35 can only accommodate one seed. When the row of spoon rings 35 moves to the top of the material trough 31, each spoon ring 35 is equipped with a seed. Then, the row of spoon rings 35 moves to the top of multiple sowing slides 36, and multiple seeds fall into multiple sowing slides 36 respectively by gravity. Taking the same sowing slide 36 as an example, the seeds in the sowing slide 36 slide to the left along the sowing slide 36. When the seed moves to the seesaw 39, the spoon ring 35 that transported the seed last time moves to the protrusion 311 in the inner slide 38 and contacts the protrusion 311, so that the spoon ring 35 presses the protrusion 311 downward, and the protrusion 311 pushes the left end of the seesaw 39 to the left through the pull rod 310. The seesaw 39 is pulled down to make the seesaw 39 tilt upward. When the seesaw 39 tilts upward, the seeds above it are pushed to the left, promoting the sliding process of the seeds. At the same time, the spoon ring 35 for conveying seeds this time moves to the right side of the tilted seesaw 39. Subsequently, the spoon ring 35 enters the inner slide 38 through the gap formed after the seesaw 39 tilts up. After that, the protrusion 311 is separated from the contact with the spoon ring 35 and resets by the elastic force of the spring, and the seesaw 39 is also reset accordingly. The position of the seesaw 39 is the connection between the inner slide 38 and the sowing slide 36. At the same time, the seesaw 39 is also located on the movement channel of the spoon ring 35. When the seesaw 39 is not tilted, a plane is formed on the sowing slide 36 to prevent smaller seeds from falling into the inner slide 38. After the plate 39 is tilted, an opening is formed at the seesaw 39, and the spoon ring 35 can enter the inner slide 38 through the sowing slide 36 without affecting the movement trajectory of the spoon ring 35. A sealing structure is formed between the multiple inner slides 38 and the left bottom of the trough 31, so that the spoon ring 35 can enter the trough 31 from the lowest point inside the trough 31, ensuring that the spoon ring 35 can contact the seeds. The seeds on the multiple sowing slides 36 slide to the left into the multiple fixed tubes 37 respectively, and then the multiple seeds fall along the multiple fixed tubes 37; a seat can be set on the frame 1, and the staff sits on the seat to perform operations such as replenishing seeds and picking out impurities. When seeds are not captured on some spoon rings 35, the staff can manually put seeds on the spoon rings 35;By setting the sowing assembly 3, when the multiple rotating disks 34 rotate, the multiple spoon rings 35 transport the seeds in rows to the multiple sowing slides 36, so that the seeds slide into the multiple fixed tubes 37 for subsequent sowing, achieving the effect of sowing single seeds in rows according to the direction of travel, and the sowing efficiency is high; by setting the seesaw 39, the seesaw 39 can move the seeds sliding in the sowing slide 36 when it is tilted, and promote the sliding process of the seeds. The seesaw 39 ensures the sealing of the sowing slide 36 without affecting the movement trajectory of the spoon ring 35, and prevents smaller seeds from sliding into the inner slide 38. ;

[0042] Since seeds of different particle sizes need to be planted in different areas, when the adjusting screw 43 is rotated, the adjusting screw 43 drives the inner sieve bucket 42 to move through the threaded connection relationship between the adjusting screw 43 and the inner sieve bucket 42, so that the multiple sieve holes of the inner sieve bucket 42 are misaligned with the multiple sieve holes of the outer sieve bucket 41, so that the effective passing area of ​​the sieve holes is reduced, so that the inner sieve bucket 42 can adjust the size of the sieved particle size through the cooperation with the outer sieve bucket 41. The multiple spoon rings 35 on the two front and rear turntables 34 contact the left ends of the two pry bars 44 in turn during movement. When the spoon rings 35 and the outer sieve bucket 41 are in contact, the spoon rings 35 and the outer sieve bucket 41 are in contact with each other. When the left end of the pry bar 44 contacts, the spoon ring 35 squeezes the left end of the pry bar 44 downward along the arc surface of the left end of the pry bar 44. Since the hinge between the outer sieve bucket 41 and the material trough 31 is located on the right side of the lever, and the two protruding rods 45 are located on the left side of the lever, when the left ends of the two pry bars 44 move downward, the right ends of the two pry bars 44 lift the outer sieve bucket 41 upward through the two protruding rods 45. Subsequently, after the two pry bars 44 are separated from the contact with the spoon ring 35, the outer sieve bucket 41 is reset by gravity, and the two pry bars 44 are reset accordingly. In the material trough 31, the pry bars 4 4 is provided with a baffle to prevent the seeds from moving to the bottom of the pry bar 44 and being pressed. Therefore, when the multiple spoon rings 35 are in motion, they use the lever principle to drive the outer sieve bucket 41 to shake up and down continuously through the two pry bars 44. When the outer sieve bucket 41 shakes, the seeds in the inner sieve bucket 42 are continuously screened, so that the smaller seeds fall into the trough 31 through the sieve holes. The staff first turns the adjusting screw 43 to screen the seeds with smaller particle sizes. After sowing the seeds with smaller particle sizes in the same area, the travel route is adjusted and the adjusting screw 43 is turned again to increase the speed. The effective passing area of ​​the large sieve holes is used to screen seeds with larger particle sizes, and the seeds with larger particle sizes are sown in another group, and so on. Through the setting of the seed selection component 4, the outer sieve bucket 41 and the inner sieve bucket 42 cooperate to screen the seeds, so that the particle size of the seeds sown in the same batch is relatively uniform. The staff can also adjust the screening particle size by adjusting the screw 43, divide the seeds of different particle sizes into multiple levels and plant them in corresponding areas, so that the seed size in the same area is uniform, and the subsequent growth of Pinellia ternata is also relatively uniform, which is convenient for subsequent care and picking.

[0043] When the rotating shaft 33 rotates, the two gears 54 are driven to rotate through the two gear rings 53. When the gears 54 rotate, the cam 55 is driven to rotate. When the cam 55 rotates, the slider 52 is driven to move back and forth up and down through the cooperation of the bearing and the slide groove. When the two sliders 52 move back and forth up and down, the movable frame 51 is driven to move back and forth up and down through the bracket. The movable frame 51 drives multiple telescopic tubes 56 to move back and forth up and down through the bracket. The multiple telescopic tubes 56 are respectively reciprocated up and down in the multiple fixed tubes 37. The seeds in the fixed tubes 37 fall into the telescopic tubes 56. The four cone head pieces 512 form a cone-shaped whole, and the four cone head pieces 512 are closed to each other when they are not in contact with the ground. When the telescopic tube 56 moves downward, it drives the four cone head pieces 512 to move downward, so that the four cone head pieces 512 make a seed hole on the soil. When the telescopic tube 56 moves, it drives the mounting ring 58 to move downward, and the mounting ring 58 drives the two sliding shafts 59 to move downward. The two sliding shafts 59 slide downward in two of the round holes of the two fixing rods 57. When the four cone head pieces 512 make a seed hole, the ends of the tops of the two sliding shafts 59 respectively abut against the two fixing rods 57, so that the two sliding shafts 59 drive the mounting ring 58 to stop moving downward. At this time, the telescopic tube 56 drives the four cone head pieces 512 to continue to move downward through the four mounting seats 511, so that the mounting ring 58 passes through the four connecting rods. The connecting arm 510 pulls the four connecting rods 513. When the connecting rods 513 are pulled, the cone head pieces 512 are driven to flip outward through the lever principle, so that when the telescopic tube 56 continues to move downward, the four cone head pieces 512 are flipped outward at the same time, and the seeds falling through the telescopic tube 56 fall on the inner side of the four cone head pieces 512. When the four cone head pieces 512 are opened, the seeds fall into the seed hole. Then, the telescopic tube 56 starts to drive the four cone head pieces 512 to move upward, and the seeds are temporarily planted in the seed hole. The four cone head pieces 512 are separated from the soil and reset by gravity, and then the next punching and sowing operation is carried out. Conventional punching operations usually require the use of a separate punching mechanism. Before sowing, multiple rows of seed holes are punched and then sowing is carried out. During the sowing process, the seeds may not be able to enter the seed holes accurately, and the punched seed holes are larger, and the workload of subsequent backfilling is larger. However, through the setting of the punching component 5, multiple telescopic tubes 56 and multiple fixed tubes 37 are formed by cooperation to form a sealed slideway for seeds, ensuring that the seeds can accurately slide to the sowing position, and the four cone head pieces 512 at the bottom of the fixed tube 37 cooperate to punch seed holes, and then the four cone head pieces 512 automatically open to place the seeds inside them in the seed holes, so that hole punching and sowing are carried out almost simultaneously, reducing the equipment investment cost, the punched seed holes are smaller, and the subsequent backfilling is more convenient.

[0044] When the telescopic tube 56 moves up and down, the groove plate 64 is driven to move up and down through the connecting rod 65. When the groove plate 64 moves back and forth, the arc groove drives the dial shaft 63 to slide back and forth along the through connection between it and the fixed tube 37, so that the dial shaft 63 drives the inner ring 61 to reciprocate in the fixed tube 37. When the inner ring 61 rotates, it drives multiple scrapers 62 to rotate synchronously. When the multiple scrapers 62 rotate, they can scrape the inner walls of the fixed tube 37 and the telescopic tube 56, so as to prevent the inner wall from being blocked. Through the setting of the anti-blocking part 6, the multiple scrapers 62 continuously scrape the inner walls of the fixed tube 37 and the telescopic tube 56 by reciprocating rotation, so as to prevent some seeds with larger particle sizes from being stuck on the inner walls of the fixed tube 37 or the telescopic tube 56 when falling, thereby causing pipeline blockage.
