Description

Technical Field

[0001] The invention belongs to the technical field of corn sowing devices, and in particular to an integrated device for intelligent sowing and seedling uniformity of silage corn. Background Art

[0002] Silage corn is one type of corn. When planting silage corn, a seeder is needed to accurately sow the seeds into the soil and cover the soil at the same time, thereby replacing the inefficient traditional methods of manual broadcasting and hole sowing, and achieving standardization and efficiency of the sowing process.

[0003] Patent publication number CN111837521B discloses an automatic agricultural corn sowing device. The invention provides an automatic agricultural corn sowing device that operates stably, replenishes corn seeds promptly, and automatically covers the soil. The device comprises a frame with multiple arcuate slots; a first connecting rod, which is provided with a sliding and rotatable first connecting rod between the arcuate slots; and an elastic member, which is connected to the frame. The device utilizes a punching mechanism to automatically drill holes in the soil. The sowing mechanism then intermittently sows corn seeds into the drilled holes in conjunction with the sowing mechanism. When the device is not in use, the first connecting rod can be locked under the arcuate slots, raising the frame and thereby keeping its components off the ground, thereby preventing wear. Furthermore, the elastic member prevents the first connecting rod from moving while the device is in operation.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] First, pour the corn seeds into the hopper, use the punching rod to punch holes in the soil, and then use the catheter to sprinkle the corn seeds into the punched holes to achieve sowing. Although there are multiple punching rods and catheters arranged horizontally to achieve multi-hole sowing, the distance between two adjacent punching rods is fixed, so the distance between two adjacent holes in a row is the same. In some cases, the roots of adjacent plants will grab soil nutrients and water in the same area due to the small distance, thereby affecting the growth of the plants. In order to avoid this situation, if the distance between adjacent plants is set too large, it is not conducive to subsequent fertilization and other operations. Therefore, it is necessary to reasonably control the distance between adjacent plants according to the growth characteristics of the seeds. In the above technical solution, it is inconvenient to control the distance between adjacent plants, and it is easy to affect the growth of plants due to unreasonable setting of the distance between plants in the same row.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. The intelligent sowing and seedling-striking integrated device for silage corn described in the present invention utilizes a multi-position sowing mechanism to realize multi-directional sowing in the same row, and at the same time can control the distance between two adjacent holes in the same row according to the growth characteristics of the seeds, so that the distance between the two adjacent holes is within a reasonable range, thereby avoiding the roots of adjacent plants from robbing the soil nutrients and water in the same area due to too small a distance, thereby affecting the growth of the plants, and also avoiding the situation where the distance between adjacent plants is set too large, which is not conducive to subsequent fertilization and other operations.

[0022] 2. The intelligent sowing and seedling uniforming integrated device for silage corn described in the present invention utilizes a seed falling auxiliary component, which can vibrate the hose by knocking on the upper and lower ends during the sowing process, thereby promoting the movement of seeds and avoiding the bending of the hose due to the adjustment of the distance between adjacent shells, which makes it difficult for seeds to pass through the hose directly and easily causes seeds to get stuck in the hose, thereby affecting normal sowing. In addition, since the knocking blocks 1 and 2 are distributed on both sides of the hose, the hose will not be continuously subjected to force in one direction, and the forces in the two directions are alternately applied to the hose, thereby avoiding the situation where the hose is difficult to reset due to continuous force in one direction, which still affects the normal falling of seeds.

Two sliding columns 35 are slidably connected to one end of the connecting rod 34. The lower end of the sliding column 35 is fixedly connected to a wheel frame 37.

One end of the spring 36 is fixedly connected to the connecting rod 34, and the other end is fixedly connected to one end of the sliding column 35.

[0043] In this embodiment, Figure 1 、 Figure 3 、 Figure 5-Figure 7 、 Figures 9-13 As shown, adjacent adjusting rods 6 are connected by a telescopic rod 13 , an electric push rod 12 is fixedly connected to one side mounting plate 9 , and the piston end of the electric push rod 12 is fixedly connected to one end of the adjusting rod 6 .

[0044] A threaded rod 8 is threadedly connected to one side of the leftmost mounting plate 9, and both ends of the threaded rod 8 are rotatably set on the storage box 2. A motor 7 is fixedly connected to one side of the storage box 2, and the output end of the motor 7 is fixedly connected to one end of the threaded rod 8. Two connecting rods 7 49 are rotatably set on one side of the leftmost and rightmost discharge pipes 10, and two connecting rods 8 50 are rotatably set on one side of the remaining discharge pipes 10. One end of the connecting rod 7 49 is rotatably connected to one end of the connecting rod 8 50, and the ends of the two adjacent connecting rods 8 50 are rotatably connected.

[0045] The middle parts of both sides of the turntable 33 are fixedly connected with groove cylinder 25 and protrusion rod 29 respectively. The adjacent groove cylinder 25 and protrusion rod 29 are plugged and slidably connected through key slots. One side of the rightmost shell 11 is fixedly connected with motor 214, and the output end of motor 214 is fixedly connected to the turntable 33.

[0046] Specifically, in the prior art, corn seeds are first poured into a hopper, a punching rod is used to punch holes in the soil, and then the corn seeds are sprinkled into the punched holes using a conduit to achieve sowing. Although multiple punching rods and conduits are arranged transversely to achieve multi-hole sowing, the spacing between two adjacent punching rods is fixed, so the spacing between two adjacent holes in a row is the same. In some cases, the roots of adjacent plants will rob the soil nutrients and water in the same area due to the small spacing, thereby affecting the growth of the plants. In order to avoid this situation, if the spacing between adjacent plants is set too large, it will not be conducive to subsequent fertilization and other operations. Therefore, it is necessary to reasonably control the spacing between adjacent plants according to the growth characteristics of the seeds. In the prior art, it is inconvenient to control the spacing between adjacent plants, and it is easy to cause the growth of plants to be affected by the unreasonable spacing between plants in the same row.

[0047] Therefore, in order to solve the above problems, when this embodiment is in use, the connecting plate 3 is connected to the external tractor, and the tractor is used to pull the frame 1 to move, and then the corn seeds are added to the storage box 2. The corn seeds will flow to the hose 23 along the hard tube 24 at the bottom of the storage box 2, and finally accumulate in the discharge pipe 10. Then, according to demand, the motor 17 is used to drive the threaded rod 18 to rotate, so that the mounting plate 9 on one side slides on the storage box 2. At the same time, with the cooperation of the connecting rod 7 49 and the connecting rod 8 50, the other mounting plates 9 also slide on the storage box 2, and the two adjacent mounting plates 9 are connected. The spacing of the mounting plate 9 changes, and similarly, the slotting knife 5 and the housing 11 also move accordingly. Then, the electric push rod 12 is used to drive the adjusting rod 6 on one side to rise and fall. Since the adjacent adjusting rods 6 are connected by the telescopic rod 13, the heights of multiple slotting knives 5 can be adjusted at the same time, so that the slotting knife 5 is inserted into the soil, and the pit depth can be controlled. Then, the tractor pulls the frame 1 to move, and the slotting knife 5 continuously digs holes in the ground. At the same time, the motor 2 14 drives the turntable 33 on one side to rotate. Since the two adjacent turntables 33 are connected by the groove cylinder 2 25 and the protrusion rod 2 39 Therefore, even if the distance between adjacent shells 11 changes, the two turntables 33 are always connected by the groove cylinder 25 and the protrusion rod 29. The multiple turntables 33 rotate synchronously, and the corn seeds inside the discharge tube 10 will fall into the elastic cloth 27 of the storage cell 26. As the turntable 33 rotates, the corn seeds above the upper edge of the storage cell 26 will be blocked by the lower edge of the discharge tube 10, while the corn seeds below the upper edge of the storage cell 26 will move with the rotation of the turntable 33. When the storage cell 26 is aligned with the through hole 28, the seeds in the storage cell 26 fall into the elastic cloth 27. The sowing operation is carried out in the pit dug by the slotting knife 5. At the same time, the pressure wheel 38 will remain in contact with the ground under the action of the spring 36, and the pressure wheel 38 will pass through the area where the shell 11 passes to perform the soil covering operation, thereby realizing multi-directional sowing in the same row, and controlling the distance between two adjacent holes in the same row according to the growth characteristics of the seeds, avoiding the roots of adjacent plants from robbing the soil nutrients and moisture in the same area due to too small a distance, affecting the growth of the plants, and also avoiding the situation where the distance between adjacent plants is set too large, which is not conducive to subsequent fertilization and other operations.

[0048] In this embodiment, Figure 4 、 Figure 7 、 Figure 8 、 Figure 14 As shown, the storage box 2 is also provided with a seed falling auxiliary component;

[0049] The seed dropping auxiliary component includes a rotating shaft 41 rotatably arranged on one side of the bottom of the storage box 2 , and a plurality of knocking blocks 42 are transversely arranged and fixedly connected to the rotating shaft 41 .

[0050] A knock block 22 is rotatably provided on one side of the discharge pipe 10, and a groove cylinder 40 and a protrusion rod 21 are fixedly connected to both sides of one end of the knock block 22 respectively. The protrusion rod 21 and the groove cylinder 40 are plugged and slidably connected through a keyway.

[0051] One end of the rotating shaft 41 is fixedly connected to the gear 2 46, and one side of the lower end surface of the storage box 2 is rotatably provided with a connecting rod 5 44, one end of the connecting rod 5 44 is rotatably provided with a connecting rod 6 45, and one end of the connecting rod 6 45 is rotatably provided with a rack 2 47, one side of the rack 2 47 is slidably connected to a slide rod 2 48, one end of the slide rod 2 48 is fixedly connected to the storage box 2, and one side of the lower end of the storage box 2 is fixedly connected to the motor 5 43, the output end of the motor 5 43 is fixedly connected to one end of the connecting rod 5 44, and one end of the rotating shaft 41 is fixedly connected to the gear 2 46, and the gear 2 46 and the rack 2 47 are engaged with each other.

[0052] One end of the knocking block 22 is fixedly connected to a gear 19, one side of the discharge pipe 10 is fixedly connected to a slide bar 20, the slide bar 20 is slidably connected to a rack 18, the rack 18 and the gear 19 are engaged with each other, a connecting rod 16 is rotatably provided on one side of the discharge pipe 10, a connecting rod 2 17 is rotatably provided on one end of the connecting rod 16, one end of the connecting rod 2 17 is rotatably connected to one end of the rack 18, a motor 3 15 is fixedly connected to one side of the discharge pipe 10, and the output end of the motor 3 15 is fixedly connected to one end of the connecting rod 16.

[0053] Specifically, in the above embodiment, although different sowing requirements can be achieved by controlling the distance between the two adjacent shells 11, when the shell 11 moves, the hose 23 will bend, which makes it difficult for the seeds to pass through the hose 23 directly. The bending of the hose 23 will affect the flow, and the seeds are likely to be stuck in the hose 23, thereby affecting normal sowing. Therefore, in order to avoid this situation, since the upper end of the hose 23 is fixed to the hard tube 24, when the main part of the hose 23 is bent, the end of the knock block 24 is still aligned with the upper end of the hose 23. Similarly, the end of the knock block 122 is still aligned with the lower end of the hose 23, and when the distance between the adjacent shells 11 changes, the protruding rod 1 21 and the groove cylinder 1 40 slide relative to each other. During the sowing process, the motor 3 15 drives the connecting rod 16 to rotate, and with the cooperation of the connecting rod 2 17, the rack 18 slides back and forth on the slide rod 1 20, thereby causing the gear 19 to rotate back and forth, and between the protruding rod 1 21 and the groove cylinder 1 40 Under the transmission, multiple knocking blocks 22 rotate simultaneously, and knocking block 1 22 knocks the bottom of hose 23. Similarly, motor 5 43 drives connecting rod 5 44 to rotate, and with the cooperation of connecting rod 6 45, rack 2 47 slides back and forth on slide rod 2 48, so that gear 2 46 and rotating shaft 41 rotate back and forth, and knocking block 2 42 knocks the upper end of hose 23. Thus, by knocking the upper and lower ends of hose 23, hose 23 vibrates, promoting the movement of seeds, avoiding the bending of hose 23 due to the adjustment of the distance between adjacent shells 11, making it difficult for seeds to pass through hose 23 straight, and seeds are easily stuck in hose 23, thereby affecting normal sowing. Moreover, since knocking block 1 22 and knocking block 2 42 are distributed on both sides of hose 23, hose 23 will not be continuously subjected to force in one direction. Forces in two directions are alternately applied to hose 23, avoiding the situation that hose 23 is difficult to reset due to continuous force in one direction, which still affects the normal falling of seeds.

[0054] In this embodiment, Figure 12 and Figure 13 As shown, a seedling leveling assembly is also provided inside the turntable 33;

[0055] The seedling thinning assembly includes a stretching rod 29 that is plugged into and slidably connected to the turntable 33 , and one end of the stretching rod 29 is fixedly connected to one side of the elastic cloth 27 .

[0056] A connecting rod four 32 is rotatably provided on one side of the inner cavity of the turntable 33, and a plurality of connecting rods three 31 are rotatably provided on the end of the connecting rod four 32. One end of the connecting rod three 31 is rotatably connected to one end of the stretching rod 29. A motor four 30 is fixedly connected to one side of the inner cavity wall of the turntable 33, and the output end of the motor four 30 is fixedly connected to the middle part of the connecting rod four 32.

[0057] Specifically, in the prior art, when corn seeds fall into the holes, it is inconvenient to control the amount of corn seeds falling into the holes, and it is easy for there to be too many or too few seeds in some areas, resulting in sparse or dense seedlings in different sowing areas, which in turn affects the uniformity of growth and is not conducive to subsequent harvesting, weeding and other work. Therefore, in order to avoid this situation, when the corn seeds fall into the storage cell 26, the motor 4 30 drives the connecting rod 4 32 to rotate, driving the connecting rod 3 31 to drive the stretching rod 29 to move. The end of the stretching rod 29 will drive the elastic cloth 27 to stretch, so that the elastic cloth 27 and the storage cell 26 form pits of different sizes, and the number of corn seeds stored in the storage cell 26 at one time is controlled. The number of corn seeds in each hole can be made close according to actual needs, so that each sowing area has uniform seedlings, which improves the uniformity of plant growth and is conducive to subsequent harvesting, weeding and other operations.

[0058] Working principle: Use the connecting plate 3 to connect with the external tractor, and use the tractor to pull the frame 1 to move, then add the corn seeds into the storage box 2, and the corn seeds will flow to the hose 23 along the hard tube 24 at the bottom of the storage box 2, and finally accumulate in the discharge pipe 10. Then, according to the needs, use the motor 17 to drive the threaded rod 18 to rotate, so that the mounting plate 9 on one side slides on the storage box 2. At the same time, with the cooperation of the connecting rod 7 49 and the connecting rod 8 50, the other mounting plates 9 also slide on the storage box 2, and the distance between the two adjacent mounting plates 9 changes. Similarly, the slotting knife 5 and the housing 11 also move accordingly, and then the electric push rod 12 is used to drive the adjusting rod 6 on one side to rise and fall. Since the adjacent adjusting rods 6 are connected by the telescopic rod 13, the heights of multiple slotting knives 5 can be adjusted at the same time, so that the slotting knife 5 is inserted into the soil, the pit depth can be controlled, and then the tractor tows the frame 1 to move, and the slotting knife 5 continuously digs holes in the ground. At the same time, the motor 2 14 drives the turntable 33 on one side to rotate. Since the two adjacent turntables 33 are connected by the groove cylinder 2 25 and the protrusion rod 2 39, even if the adjacent The distance between the shells 11 changes, and the two turntables 33 are always connected by the groove cylinder 25 and the protrusion rod 2 39. The multiple turntables 33 rotate synchronously, and the corn seeds inside the feed tube 10 will fall onto the elastic cloth 27 of the storage cell 26. As the turntable 33 rotates, the corn seeds above the upper edge of the storage cell 26 will be blocked by the lower edge of the feed tube 10, and the corn seeds below the upper edge of the storage cell 26 will move with the rotation of the turntable 33. When the storage cell 26 is aligned with the through hole 28, the seeds in the storage cell 26 fall into the elastic cloth 27 of the slotted knife. 5, sowing operation is carried out in the pit dug by the shell 11. At the same time, the pressing wheel 38 will keep in contact with the ground under the action of the spring 36, and the pressing wheel 38 will pass through the area where the shell 11 passes to carry out soil covering operation, thereby realizing multi-directional sowing in the same row and controlling the distance between two adjacent holes in the same row according to the growth characteristics of the seeds, thereby preventing the roots of adjacent plants from robbing soil nutrients and water in the same area due to too small a distance, thereby affecting the growth of the plants, and also avoiding the situation where the distance between adjacent plants is set too large, which is not conducive to subsequent fertilization and other operations;Since the upper end of the hose 23 is fixed to the hard tube 24, when the main part of the hose 23 is bent, the end of the knock block 2 42 is still aligned with the upper end of the hose 23. Similarly, the end of the knock block 1 22 is still aligned with the lower end of the hose 23. When the distance between adjacent shells 11 changes, the protruding rod 1 21 and the groove cylinder 1 40 slide relative to each other. During the sowing process, the motor 3 15 drives the connecting rod 1 16 to rotate, and with the cooperation of the connecting rod 2 17, the rack 18 slides back and forth on the slide bar 1 20, thereby causing the gear 19 to rotate back and forth, and Under the transmission of the protruding rod 21 and the groove cylinder 40, the multiple knocking blocks 22 rotate at the same time, and the knocking block 22 knocks the bottom of the hose 23. Similarly, the motor 5 43 drives the connecting rod 5 44 to rotate, and with the cooperation of the connecting rod 6 45, the rack 2 47 slides back and forth on the slide rod 2 48, so that the gear 2 46 and the rotating shaft 41 rotate back and forth, and the knocking block 2 42 knocks the upper end of the hose 23. By knocking the upper and lower ends of the hose 23, the hose 23 is vibrated, which promotes the movement of the seeds and avoids Due to the adjustment of the distance between adjacent shells 11, the hose 23 is bent, making it difficult for the seeds to pass through the hose 23 straightly, and the seeds are easily stuck in the hose 23, thereby affecting normal sowing. In addition, since the knocking block 1 22 and the knocking block 2 42 are distributed on both sides of the hose 23, the hose 23 is not continuously subjected to force in one direction. The forces in two directions are alternately applied to the hose 23, thereby avoiding the situation where the hose 23 is difficult to reset due to continuous force in one direction, which still affects the normal falling of the seeds. When the corn seeds fall into the storage cell 26, the motor 4 30 drives the connecting rod 4 32 to rotate, driving the connecting rod 3 31 to drive the stretching rod 29 to move. The end of the stretching rod 29 drives the elastic cloth 27 to stretch, so that the elastic cloth 27 and the storage cell 26 form pits of different sizes, thereby controlling the number of corn seeds stored in the storage cell 26 at one time. The number of corn seeds in each pit can be made close according to actual needs, thereby making each sowing area uniform in germination, improving the uniformity of plant growth, and facilitating subsequent harvesting, weeding and other operations.
