Description

Technical Field

[0001] This invention relates to the field of seeding equipment technology, specifically a corn fertilization contour seeder. Background Technology

[0002] A seed drill is a type of planting machinery that uses crop seeds as the object of sowing. It can complete a series of actions such as furrowing, seeding, soil covering, and compaction during the sowing process, thereby greatly improving the planting efficiency of crops such as corn, peanuts, and beans, and effectively reducing the amount and intensity of labor for farmers when carrying out planting operations.

[0003] However, due to the complex terrain in the fields, there are often slopes of varying sizes and heights. When the seeder is pulled to open furrows and sow seeds, the depth of the furrows it opens varies due to the slopes. This results in poor sowing effect for crop seeds, and the seeds are easily "lost" due to the shallow soil covering depth and the impact of rainwater.

[0004] Furthermore, existing seeders use a traction drive system, resulting in a triangular force relationship between the seeder and the two sets of rear wheels. This makes them prone to tipping over when towing and turning, posing a significant safety hazard. Alternatively, they require a large turning radius to maintain balance during turns, which severely affects the seeding efficiency of the seeder.

[0005] Therefore, there is an urgent need for a structure for seeders to solve the defects of existing seeders in actual operation. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] This invention provides a corn fertilization contour-following seeder, which features a ditching component that can maintain the depth of its furrowing components according to changes in terrain, resulting in better seed sowing. It also reduces the risk of tipping over when turning and eliminates the need for a large turning radius to maintain balance, leading to higher sowing efficiency. This invention solves the problems caused by complex field terrain with varying slopes, where the depth of the furrows varies with the slope, resulting in poor seed sowing and a high risk of seed loss due to insufficient soil coverage and rain impact. Furthermore, existing seeders, using a traction drive system, create a triangular force relationship between the seeder and its two rear wheels, making them prone to tipping over during turns, posing a significant safety hazard, or requiring a large turning radius to maintain balance during turns, thus severely impacting sowing efficiency.

[0008] (II) Technical Solution

[0009] This invention provides the following technical solution: a corn fertilizer contour seeder, comprising a frame, a suspension frame fixedly installed on one side of the top of the frame, a fertilizer box fixedly installed in the middle of the top of the frame, and a seed box fixedly installed on the other side of the top of the frame, a ground wheel fixedly installed on the other side of the bottom of the frame, and a furrowing assembly provided on one side of the bottom of the frame, the furrowing assembly comprising a crossbeam, a first connecting plate pinned to the top of the left side of the crossbeam, and a second connecting plate pinned to the bottom of the right side of the crossbeam, the crossbeam being movably connected to the frame through the first connecting plate and the second connecting plate, a tension spring forming a transmission connection between the first connecting plate and the second connecting plate, a first furrow opener fixedly installed at the right end of the crossbeam and communicating with the fertilizer box on the frame, a second furrow opener fixedly installed at the left end of the crossbeam and communicating with the seed box on the frame, the second furrow opener and the seed box being connected through a seeder fixedly installed in the middle of the bottom of the frame, and a soil covering wheel provided on one side of the bottom of the second furrow opener.

[0010] Preferably, a set of bearing transmission structures is provided in the middle of the bottom end of the frame, and a rolling friction connection is formed between the bearing structure and the side of the top of the second trencher.

[0011] Preferably, the inner and outer positions of the first trencher and the second trencher on the trenching assembly are staggered and not on the same plane.

[0012] Preferably, the frame adopts a square frame structure welded from square tubes, and the inner wall of the square tube on one side of the suspension frame is set as a circular structure. Guide rods extending to the outside of the square tube on this side are fixedly installed inside. A sliding block with an "I" shape is movably sleeved on the outer surface of the guide rod and inside the square tube on this side. An inner piston is movably sleeved on the outer surface of the crossbar on the sliding block.

[0013] Preferably, the sliding block divides the inner cavity of the side tube into two chambers, left and right, and each chamber is connected to the hydraulic pump station on the seeder through a set of valve bodies.

[0014] Preferably, the inner cavity of the sliding block is filled with insulating grease, and a cavity is provided inside the inner piston so that the buoyancy it experiences is greater than its own weight.

[0015] Preferably, the sliding block has a set of connecting grooves inside that connect the left and right chambers of the inner piston.

[0016] Preferably, a set of first contact guide blocks is provided at the left and right ends of the inner side of the sliding block, and an electrical connection is formed between the sliding block and the external control system and hydraulic pump station through the guide rod. A set of second contact guide blocks is provided at the left and right ends of the outer side of the inner piston.

[0017] Preferably, the sliding block moves in the same direction as the tilting direction of the seeder under the action of liquid pressure.

[0018] (III) Beneficial Effects

[0019] The present invention has the following beneficial effects:

[0020] 1. This corn fertilizer contour seeder features a ditching component and its structure that allows for a movable connection between the ditching device and the frame. This connection can adjust to changes in terrain, enabling the ditching component and frame to float at varying intensities. This ensures that the furrows created by the first and second ditching devices maintain a set depth, preventing variations in depth due to terrain changes. This effectively improves the seeding efficiency and prevents seeds from being "lost" due to shallow soil coverage and rain impact. The machine exhibits high stability and reliability.

[0021] 2. In this corn fertilizing contour seeder, the sliding block and its linkage structure can generate a set of feedback signals when the seeder tilts due to turning, which are transmitted to the control system and trigger the hydraulic pump station on the seeder. Under the action of hydraulic transmission, the sliding block is forced to move to the corresponding side, changing the center of gravity of the seeder to maintain its balance and making it less prone to tipping over. It also eliminates the need for a large turning radius to maintain its balance, effectively improving the seeder's sowing efficiency. Attached Figure Description

[0027] 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.

[0028] Please see Figure 1 A corn fertilizing contour seeder includes a frame 1. A suspension frame 2 for connection to a traction mechanism is fixedly installed on one side of the top of the frame 1. A fertilizer box 3 for loading fertilizer is fixedly installed in the middle of the top of the frame 1. A seed box 4 for loading crop seeds is fixedly installed on the other side of the top of the frame 1. A ground wheel 5 is fixedly installed on the other side of the bottom of the frame 1 to support and drive the seeder and to compact the sown crop seeds. Two sets of parallel furrowing components 6 are provided on one side of the bottom of the frame 1. Figure 3As shown, the trenching assembly 6 includes a crossbeam 7. A first connecting plate 8 is pinned to the top left side of the crossbeam 7, and a second connecting plate 9 is pinned to the bottom right side of the crossbeam 7. The crossbeam 7 is movably connected to the frame 1 via the first connecting plate 8 and the second connecting plate 9, forming a four-bar linkage. A tension spring 10 is provided between the first connecting plate 8 and the second connecting plate 9 to form a transmission connection. The amplitude intensity between the trenching assembly 6 and the frame 1 can be adjusted by adjusting the length of the tension spring 10. A first trencher 11 for opening trenches on the ground is fixedly installed at the right end of the crossbeam 7 and is connected to the fertilizer box 3 on the frame 1. A corresponding amount of fertilizer is applied to the trenches while they are being opened. A second trencher 12, connected to the seed box 4 on the frame 1, is fixedly installed at the left end of the crossbeam 7. Crop seeds stored in the seed box 4 can be placed into the trenches while they are being opened. Figure 2 As shown, the second furrow opener 12 is connected to the seed box 4 by a seeder 14 fixedly installed at the bottom center of the frame 1, thereby accurately distributing the crop seeds in the seed box 4 into the furrows opened by the second furrow opener 12. A soil covering wheel 13 is provided on one side of the bottom end of the second furrow opener 12 for covering the soil in the furrows.

[0029] In this technical solution, a set of bearing transmission structure is provided in the middle of the bottom end of the frame 1, and a rolling friction connection is formed between it and the side of the top of the second furrow opener 12. This can limit the amplitude of the back-and-forth swing of the second furrow opener 12, and effectively reduce the frictional resistance between the furrow opening components 6 when they float up and down with the terrain, thereby reducing the wear problem between the various parts of the seeder.

[0030] In this technical solution, the inner and outer positions of the first furrow opener 11 and the second furrow opener 12 on the furrowing component 6 are staggered and not on the same plane, so that fertilizer and crop seeds can be placed in the two furrows respectively, preventing fertilizer from causing "damage" to crop seeds or seedlings after germination.

[0031] like Figure 4 As shown, in this technical solution, the frame 1 adopts a square frame structure welded from square tubes, and the inner wall of the square tube on one side of the suspension frame 2 is set as a circular structure. The guide rods 15 extending to the outside of the two ends are fixedly installed inside the square tube on this side. The outer surface of the guide rod 15 and the inside of the square tube on this side are movably sleeved with a sliding block 16 in the shape of an "I". The sliding block 16 is made of a metal material with a high density. The outer surface of the crossbar on the sliding block 16 is movably sleeved with an inner piston 17.

[0032] In this technical solution, the sliding block 16 divides the inner cavity of the side square tube into two chambers, left and right, and connects them to the hydraulic pump station on the seeder through a set of valve bodies. The sliding block 16 is then driven to move left and right through hydraulic transmission, and the center of gravity of the seeder is adjusted so that it is not easy to tip over when it is tractioned and turns.

[0033] In this technical solution, the inner cavity of the sliding block 16 is filled with insulating grease, and a cavity 18 is opened inside the inner piston 17 so that the buoyancy it receives is greater than its own weight. Therefore, when the seeder tilts, the inner piston 17 can move along the central axis of the side tube under the action of buoyancy.

[0034] In this technical solution, the sliding block 16 has a set of connecting grooves 21 that connect the left and right chambers of the inner piston 17. When the inner piston 17 moves left and right, the insulating grease in one chamber can be squeezed and transported to the other chamber, so that the inner piston 17 has a high degree of flexibility when it moves left and right as the seeder tilts.

[0035] In this technical solution, a set of first contact guide blocks 19 are respectively provided at the left and right ends of the inner side of the sliding block 16, and are electrically connected to the external control system and hydraulic pump station through the guide rod 15. A set of second contact guide blocks 20 are respectively provided at the left and right ends of the outer side of the inner piston 17. When the first contact guide block 19 and the second contact guide block 20 make contact, a feedback signal can be generated and transmitted to the control system, triggering the hydraulic pump station.

[0036] In this technical solution, the sliding block 16 moves in the same direction as the tilting direction of the seeder under the action of liquid pressure. When the seeder tilts to the left, the sliding block 16 moves to the left under the squeezing transmission of the hydraulic pump station; and when the seeder tilts to the right, the sliding block 16 moves to the right under the squeezing transmission of the hydraulic pump station.

[0037] The usage method and working principle of this embodiment are as follows:

[0038] First, the seeder is fixedly installed on the traction mechanism via the suspension frame 2. Fertilizer and crop seeds are placed in the fertilizer box 3 and seed box 4 respectively. At the same time, the fertilizer delivery rate is adjusted, and the seed delivery spacing is adjusted using the seeder 14. Then, the hydraulic control system and circuit control system are connected to it. The traction mechanism then drives the seeder to carry out a series of sowing operations in the field, such as furrowing, seeding, covering with soil, and compaction.

[0039] When there are undulating slopes in the field, the horizontal frame 7 and its structure and the frame 1 will float up and down to different degrees due to the change of terrain. This will cause the first furrow opener 11 and the second furrow opener 12 on the ground to always maintain the set depth of the furrows, and will not be deeper or shallower due to the change of terrain. This will make the seeder better at sowing crop seeds.

[0040] When the seeder tilts due to turning, the cavity 18 inside the tube above the frame 1 near the suspension frame 2 moves along its central axis until the second contact guide block 20 on the corresponding side contacts the first contact guide block 19 on the sliding block 16. This generates a set of feedback signals that are transmitted to the control system and trigger the hydraulic pump station on the seeder. Under the action of hydraulic transmission, the sliding block 16 is forced to move to the corresponding side to change the center of gravity of the seeder, so as to keep it balanced and prevent it from tipping over.
