Description

Technical Field

[0001] This utility model relates to the field of corn planting technology, specifically a corn planter suitable for ridge-side operations. Background Technology

[0002] In the process of large-scale corn planting, ridge cultivation is a widely used planting mode. This mode can effectively improve soil permeability, increase soil temperature and facilitate field management. Ridge-side sowing, as a key link in ridge cultivation, has high requirements for the adaptability and operational stability of sowing equipment.

[0003] Currently, most corn planters on the market have a general-purpose structure, and their specialized design for ridge-side planting is significantly insufficient. On the one hand, the ridge-side positioning and support components of existing planters are mostly fixed structures, unable to be flexibly adjusted according to the ridge width under different regional and soil conditions during actual planting. Due to varying planting habits and agricultural technology promotion requirements among farmers in different regions, corn planting ridge widths often vary, such as 1.2 meters and 1.5 meters. Fixed-structure ridge-side components are difficult to adapt to ridges of different widths, leading to problems such as loose ridge-side contact and positioning deviations during operation, which in turn cause planting position errors and affect the uniformity of subsequent corn growth.

[0004] On the other hand, the existing corn planters have poor coordination between feeding and movement. Although some planters have feeding functions, they lack stable movement support and quantitative control design. When moving in the field, the equipment is prone to shaking or tilting due to factors such as uneven soil looseness and obstruction by field debris. This results in unstable distance between the feeding port and the soil, and seeds are prone to piling up or being missed when falling. At the same time, the quantitative feeding mechanism of some planters is not precise enough, and it is impossible to accurately control the amount of a single seed falling, which can easily lead to seed waste or insufficient planting density, further affecting the planting efficiency and yield of corn.

[0005] Therefore, a corn planter suitable for ridge-side operations is needed to solve the aforementioned problems. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a corn planter suitable for ridge-side operations, which has the advantages of adapting to different ridge widths and ensuring stable planting, and solves the problems of poor adaptability and low planting accuracy that currently exist in corn planters operating on ridge sides.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a corn planter suitable for ridge-side operations, comprising a frame, a dual-shaft motor fixedly connected to the top of the frame, both output shafts of the dual-shaft motor being fixedly connected to lead screws via couplings, the other end of each lead screw being rotatably connected to a bearing seat, and the bearing seat being fixedly connected to the frame; symmetrically arranged movable openings are provided on the top of the frame, and the movable openings are located directly below the lead screws; threaded blocks are threadedly connected to the surface of the lead screws, and the threaded blocks are slidably connected to the frame; the frame... Support bars are symmetrically fixedly connected to both sides of the machine, and a sliding rod is fixedly connected between the two support bars. Support wheels are provided on the outer side of the support bars. A support frame is fixedly connected to the bottom of the threaded block. A sliding opening is opened on the surface of the support frame, and the sliding opening is slidably connected to the sliding rod. A conical ridge side wheel is slidably connected to the inner side of the support frame, and the conical ridge side wheel is used in conjunction with the sliding rod. A seed storage box is fixedly connected to the top of the machine frame. A seeder with a quantitative feeding function is connected to the bottom of the seed storage box, and the seeder is located at the center line of the machine frame.

[0008] As a preferred embodiment of this utility model, an outer scraper ring is fixedly connected to the outer side of the support frame, and a stepped inner scraper ring is fixedly connected to the inner side of the conical ridge side wheel.

[0009] As a preferred embodiment of this utility model, the surface of the seeder is symmetrically fixedly connected to a fixed frame, and the inner side of the fixed frame is rotatably connected to a ground wheel, which is driven by a reduction motor. The surface of the ground wheel is provided with a number of uniformly arranged conical blocks in a ring.

[0010] As a preferred embodiment of this utility model, the bottom of the seeder is symmetrically and fixedly connected with auxiliary wheels, and the two auxiliary wheels are respectively located on both sides of the discharge port of the seeder. The rear side of the seeder is rotatably connected with a pressure wheel.

[0011] As a preferred embodiment of this utility model, the front side of the frame is symmetrically and fixedly connected with hinge members, the hinge members are internally hinged with connecting frames, and the other end of the connecting frames is fixedly connected with a traction ear for connecting external traction equipment.

[0012] As a preferred embodiment of this invention, the top of the frame is symmetrically and fixedly connected with a dustproof frame, and the dustproof frame is located on the outside of the lead screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model utilizes the synergistic effect of a dual-axis motor, lead screw, bearing seat, moving port, threaded block, support bar, slide bar, support frame, and conical ridge-side wheel fixedly connected to the top of the frame. By starting the dual-axis motor, the lead screw is rotated, causing the threaded block to slide along the frame and move the support frame and conical ridge-side wheel along the slide bar. This allows for flexible adjustment of the spacing between the conical ridge-side wheels, thus adapting to ridges of different widths. This solves the problem of existing corn planters having difficulty in flexibly adjusting the ridge-side working parts according to the ridge width and having poor adaptability, thereby improving the equipment's applicability to different planting scenarios.

[0014] 2. This utility model, through a seed storage box fixed at the top of the frame and a quantitative feeder connected to the bottom of the seed storage box and located at the center line of the frame, combined with support wheels on the outside of the support bars, enables the feeder to stably and quantitatively feed seeds when the equipment moves through the traction structure, ensuring that the seeds fall evenly into the soil. At the same time, the support wheels ensure the overall movement of the equipment is stable, avoiding seeding position deviation or uneven feeding due to equipment shaking. Compared with some existing seeders that have low seeding accuracy and poor seeding stability, this effectively improves the uniformity and accuracy of corn seeding, laying the foundation for subsequent corn seedling uniformity and yield improvement.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 4 As shown, this utility model provides a corn planter suitable for ridge-side operations, including a frame 1. A dual-shaft motor 2 is fixedly connected to the top of the frame 1. Both output shafts of the dual-shaft motor 2 are fixedly connected to lead screws 3 via couplings. The other end of the lead screw 3 is rotatably connected to a bearing seat 4, and the bearing seat 4 is fixedly connected to the frame 1. The top of the frame 1 has symmetrically opened movable openings 5, and the movable openings 5 ​​are located directly below the lead screws 3. The surface of the lead screw 3 is threaded with threaded blocks 6, and the threaded blocks 6 are slidably connected to the frame 1. The two sides of the frame 1 are symmetrically fixedly connected to... A support bar 7 is attached, and a sliding rod 8 is fixedly connected between two support bars 7. A support wheel is provided on the outer side of the support bar 7. A support frame 9 is fixedly connected to the bottom of the threaded block 6. A sliding opening is provided on the surface of the support frame 9, and the sliding opening is slidably connected to the sliding rod 8. A conical ridge side wheel 10 is slidably connected to the inner side of the support frame 9, and the conical ridge side wheel 10 is used in conjunction with the sliding rod 8. A seed storage box 11 is fixedly connected to the top of the frame 1. A seeder 12 with a quantitative feeding function is connected to the bottom of the seed storage box 11, and the seeder 12 is located at the center line of the frame 1.

[0019] refer to Figure 2 and Figure 3 The outer side of the support frame 9 is fixedly connected to a mud scraper outer ring 13, and the inner side of the conical ridge side wheel 10 is fixedly connected to a stepped mud scraper inner ring 14.

[0020] As a technical optimization of this utility model, the cooperation between the outer scraper ring 13 and the stepped inner scraper ring 14 allows for the simultaneous removal of soil adhering to the surface of the conical ridge side wheel 10 during its rolling operation. The stepped structure of the inner scraper ring 14 scrapes away deep soil layer by layer from the inner side of the wheel, while the outer scraper ring 13 cleans the soil from the outer surface of the wheel. This prevents soil accumulation from affecting the fit and operational stability of the conical ridge side wheel 10 to the ridge side, reduces the frequency of equipment downtime for cleaning, and improves sowing efficiency.

[0021] refer to Figure 4 The surface of the seeder 12 is symmetrically fixedly connected to a fixed frame 15, and the inner side of the fixed frame 15 is rotatably connected to a ground wheel 16, which is driven by a reduction motor. The surface of the ground wheel 16 is provided with several annularly arranged conical blocks 17.

[0022] As a technical optimization of this utility model, a stable connection between the ground wheel 16 and the seeder 12 is achieved through the fixing frame 15. When the reduction motor drives the ground wheel 16 to rotate, the conical blocks 17 arranged in a ring on its surface can be inserted into the soil. On the one hand, the conical blocks 17 can enhance the friction between the ground wheel 16 and the soil, preventing the ground wheel 16 from slipping on soft soil and ensuring the synchronicity of the seeder 12's movement with the equipment; on the other hand, the insertion of the conical blocks 17 into the soil can initially loosen the soil in the sowing area, creating favorable conditions for subsequent seed planting and germination.

[0023] refer to Figure 4 The bottom of the seeder 12 is symmetrically and fixedly connected with auxiliary wheels 18, and the two auxiliary wheels 18 are located on both sides of the discharge port of the seeder 12. The rear side of the seeder 12 is rotatably connected with a pressure wheel 19.

[0024] As a technical optimization of this utility model, auxiliary wheels 18 are set on both sides of the discharge port of the seeder 12 to support the seeder 12, ensuring that the seeder 12 remains horizontal during operation and avoiding inconsistent distance between the discharge port and the soil due to equipment tilt, thereby ensuring the accuracy of seed falling position and achieving uniform sowing. The pressure roller 19 on the rear side of the seeder 12 can compact the soil in the sowing area in time after the seeds fall into the soil. On the one hand, it can make the seeds in close contact with the soil, which is conducive to the seeds absorbing water and nutrients. On the other hand, it can prevent the seeds from being exposed due to wind or rain, thereby improving the seed survival rate.

[0025] refer to Figure 2 The front side of the frame 1 is symmetrically fixedly connected with hinges 20, and the inside of the hinges 20 is hinged with a connecting frame 21. The other end of the connecting frame 21 is fixedly connected with a traction ear 22 for connecting external traction equipment.

[0026] As a technical optimization of this utility model, the connecting frame 21 and the frame 1 are hinged by the hinge member 20, so that the connecting frame 21 can rotate around the hinge point. When the equipment is connected to traction equipment (such as tractors) of different heights or angles, the connecting frame 21 can adaptively adjust the angle by rotating, ensuring that the traction ear 22 and the connection part of the traction equipment are accurately connected, avoiding uneven force during the traction process due to the deviation of the connection angle, reducing the risk of damage to the frame 1 and other components, and ensuring the stability of the equipment during traction operation.

[0027] refer to Figure 3 A dustproof frame 23 is symmetrically fixedly connected to the top of the frame 1, and the dustproof frame 23 is located on the outside of the lead screw 3. A retractable protective sleeve (not shown) is fitted on the surface of the lead screw 3.

[0028] As a technical optimization of this utility model, the dustproof frame 23 can block larger particles of debris (such as crop straw, stones, etc.) from entering the area where the lead screw 3 is located, thus preventing debris from jamming the fit between the lead screw 3 and the threaded block 6. At the same time, the retractable protective sleeve on the surface of the lead screw 3 can tightly wrap the lead screw 3, effectively isolating it from dust, dirt and moisture, preventing the surface of the lead screw 3 from rusting or being worn by impurities, ensuring the flexibility of the transmission between the lead screw 3 and the threaded block 6, extending the service life of the lead screw 3, and ensuring the stable operation of the equipment transmission system.

[0029] Working principle and usage process of this utility model: 1. Pre-operation preparation: First, using the hinge 20 and hinged connecting frame 21 symmetrically fixed to the front side of the frame 1, precisely connect the traction ear 22 fixed to the other end of the connecting frame 21 to the external traction equipment (such as a tractor). Adjust the angle of the connecting frame 21 using the rotational characteristics of the hinge 20 to ensure that the traction ear 22 is in close contact with the connection part of the traction equipment and that the force is evenly distributed. Then, add corn seeds to the seed storage box 11 fixed to the top of the frame 1. Check the seeder 12 with quantitative feeding function connected to the bottom of the seed storage box 11 to ensure that its feeding channel is unobstructed. At the same time, confirm that the ground wheel 16 (driven by a reduction motor) rotatably connected to the inner side of the fixed frame 15 symmetrically fixed to the surface of the seeder 12, the conical blocks 17 evenly arranged in a ring on the surface of the ground wheel 16, the auxiliary wheels 18 symmetrically fixed to the bottom of the seeder 12 and located on both sides of the discharge port, and the pressure wheel 19 rotatably connected to the rear side of the seeder 12 are all in normal condition. Check the top of the frame 1. The following components are fixedly connected: a dual-shaft motor 2, a lead screw 3 fixedly connected to the output shaft of the dual-shaft motor 2 via a coupling, a bearing seat 4 rotatably connected to the other end of the lead screw 3 and fixed to the frame 1, a movable port 5 symmetrically opened on the top of the frame 1 and located directly below the lead screw 3, a threaded block 6 threadedly connected to the surface of the lead screw 3 and slidably connected to the frame 1, support bars 7 symmetrically fixedly connected to both sides of the frame 1, a slide rod 8 fixedly connected between the two support bars 7, a support wheel set on the outside of the support bar 7, a support frame 9 fixedly connected to the bottom of the threaded block 6 and having a sliding port on its surface that slidably connects to the slide rod 8, a conical ridge side wheel 10 connected to the inside of the support frame 9 via a bearing and used in conjunction with the slide rod 8, a scraper outer ring 13 fixedly connected to the outside of the support frame 9, a stepped scraper inner ring 14 fixedly connected to the inside of the conical ridge side wheel 10, a dustproof frame 23 symmetrically fixedly connected to the top of the frame 1 and located outside the lead screw 3, and a retractable protective sleeve fitted on the surface of the lead screw 3. All components are undamaged and unobstructed.

[0030] 2. Equipment debugging: Start the dual-axis motor 2. The two output shafts of the dual-axis motor 2 drive the lead screw 3 to rotate around the bearing seat 4 through the coupling. When the lead screw 3 rotates, it drives the threaded block 6 connected by the surface thread to slide along the frame 1 (the moving port 5 provides space for the threaded block 6 to move). The threaded block 6 drives the support frame 9 fixedly connected at the bottom to move. The support frame 9 slides along the slide bar 8 between the two support bars 7 through the sliding port on the surface, which in turn drives the conical ridge side wheel 10 on the inner side of the support frame 9 to move along the slide bar 8. Adjust the distance between the two conical ridge side wheels 10 according to the actual ridge width so that the conical ridge side wheels 10 can fit against the ridge side. After the adjustment is completed, turn off the dual-axis motor 2.

[0031] 3. Sowing Operation: Start the external traction equipment. The traction equipment moves the frame 1 via the traction lug 22, connecting frame 21, and hinge 20. The support wheels on the outer sides of the support bars 7 on both sides of the frame 1 roll to assist the equipment's movement. Simultaneously, activate the quantitative feeding function of the seeder 12 and the reduction motor of the ground wheel 16. The reduction motor drives the ground wheel 16 to rotate, and the conical blocks 17 on the surface of the ground wheel 16 insert into the soil, increasing the friction between the ground wheel 16 and the soil to prevent slippage, while also initially loosening the soil in the sowing area. The auxiliary wheels 18 on both sides of the bottom of the seeder 12 roll to support the seeder 12, ensuring that the seeder 12 is level. The seeder 12 will... The seeds in the seed storage box 11 are quantitatively delivered to the discharge port and fall into the soil. As the equipment moves, the pressure roller 19 on the rear side of the seeder 12 rolls to compact the soil in the area where the seeds fall. During the rolling and contacting of the conical ridge side wheel 10 with the ridge side, the outer scraper ring 13 on the outside of the support frame 9 cooperates with the stepped scraper inner ring 14 on the inside of the conical ridge side wheel 10 to remove the soil attached to the surface of the conical ridge side wheel 10 and prevent soil accumulation from affecting the operation. The dustproof frame 23 on the top of the frame 1 prevents larger debris from entering the area of ​​the lead screw 3. The retractable protective sleeve on the surface of the lead screw 3 isolates dust and moisture and protects the transmission between the lead screw 3 and the threaded block 6.

[0032] 4. End of operation: Turn off the external traction equipment, the reducer motor of the seeder 12 and the ground wheel 16, disconnect the traction ear 22 from the traction equipment, clean the remaining seeds in the seed storage box 11 and the residual seeds in the feeding channel of the seeder 12, check the condition of each component, and thoroughly clean the soil on the surface of the conical ridge side wheel 10, the ground wheel 16, the pressure wheel 19 and other components, and store the equipment after ensuring it is clean.

[0033] It should be noted that a controller (not shown) for controlling various electrical components can be installed on the top of frame 1. This controller can be an SPC-SFMC-X2214A controller, which is one of the core components of the precision seeder's electronic control system. It is paired with the 7-inch display screen SPD-070-Ax and communicates via a CAN bus. Its protection rating reaches IP67, and it can operate under 8-32VDC voltage, exhibiting strong temperature adaptability. The seeder controller is mounted on the seeder and is responsible for calculating the vehicle speed, controlling the seeding negative pressure, collecting the number of seeds, and controlling the seeding distance. The 7-inch display screen is mounted in the external tractor cab and can display various data such as equivalent seeding quality and target seeding length, and also serves as an alarm information display function. The entire system has a distributed layout, excellent performance, and can meet the needs of precision production operations in smart agriculture.
