Description

Technical Field

[0001] This utility model belongs to the field of sowing and planting technology, and in particular a sowing device for high-altitude sandy areas. Background Technology

[0002] In modern agricultural practice, especially in unique and complex geographical environments such as plateau sandy areas, traditional sowing methods often face numerous challenges. Currently, when sowing in plateau sandy areas, traditional sowing tools and techniques, due to their limitations, are unable to meet the demands for efficient and precise sowing. Specifically, existing sowing equipment typically has some shortcomings, such as: most traditional sowing equipment is designed with a fixed structure, making it difficult to cope with complex and varied terrain, especially the loose and uneven surface conditions of plateau sandy areas. Due to the lack of flexible angle and sowing insertion height adjustment structures, these devices cannot guarantee that the sowing tube can be accurately inserted into the soil to the predetermined depth when facing ground with different slopes and undulations.

[0003] If this problem is not addressed, inconsistent sowing depths will occur, directly impacting seed germination rates and growth. When sowing on sandy ground, if seeds are sown too shallowly, they are easily covered by sand or exposed on the surface, making them vulnerable to bird predation; if sown too deep, they may suffocate due to lack of oxygen, affecting germination rates. In the long run, this not only reduces crop yields but may also increase costs due to the need for reseeding. Utility Model Content

[0004] The purpose of this invention is to provide a seeding device for high-altitude sandy areas to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a seeding device for high-altitude sandy areas, comprising a seeding cart, a power distribution equipment box on the seeding cart, a seed box above the power distribution equipment box, an upper frame plate fixed between the power distribution equipment box and the seed box, a rocking rod rotatably mounted on one end of the upper frame plate, and a centralized seeding box mounted on the free end of the rocking rod away from the upper frame plate via a lifting component;

[0006] The centralized seeding box has multiple seed storage channels inside. Each seed storage channel has multiple seed feeding holes evenly spaced on its inner bottom wall. Each seed feeding hole is connected to a seeding tube at its bottom, which is located below the centralized seeding box. The bottom end of each seeding tube is integrally connected to a seed insertion tip that is inserted into the sand. A seeding solenoid valve is installed between each seed insertion tip and the adjacent seeding tube. The air pump in the power distribution equipment box is connected to the multiple seed storage channels of the centralized seeding box through an air pipe.

[0007] In this preferred embodiment, each of the seeding holes located on the bottom surface of the centralized seeding box is fixed with a seeding connecting pipe, and the top of each seeding tube is integrally connected with an external threaded pipe, which is threadedly connected to the seeding connecting pipe.

[0008] In a preferred embodiment of this scheme, the top surface of the centralized seeding box is equipped with a detachable top plate by bolts, and the lifting component includes a hydraulic lifting column installed on the top surface of the detachable top plate, with the tail end of the hydraulic lifting column being bolted to the bottom surface of the free end of the rocker arm.

[0009] In a preferred embodiment, the outer wall of the seed box is connected to a seeding and feeding pipe, and the seeding and feeding pipe is sealed to the end of the transparent seeding pipe away from the centralized seeding box.

[0010] In a preferred embodiment, a semi-circular positioning plate is welded to one outer wall of the upper frame plate, and an arc-shaped positioning groove is formed inside the semi-circular positioning plate. An arc-shaped positioning slider that can slide in the arc-shaped positioning groove is welded to the bottom surface of the rocker arm.

[0011] In a preferred embodiment, a servo motor is fixed to the bottom surface of one end of the upper frame plate near the semi-circular positioning plate. The output shaft of the servo motor rotates through the upper frame plate and is fixedly connected to one end of the rocker arm, so that the servo motor drives the rocker arm to rotate.

[0012] In a preferred embodiment, the top surface of the seed box is equipped with a cover plate, the top surface of the cover plate is symmetrically equipped with a handle, the end of the seeding cart away from the seeding tube is equipped with a handrail, and the bottom surface of the seeding cart is equipped with wheels.

[0013] In this preferred embodiment, both the transparent seeding tube and the air tube are equipped with electromagnetic valves at the ends near the centralized seeding box. When it is necessary to open the channel of the transparent seeding tube or the air tube, the corresponding electromagnetic valve is opened.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0015] This seeding device for high-altitude sandy areas achieves a series of automated operations from seed delivery and positioning to sowing through the coordinated work of components such as air pumps, servo motors, hydraulic lifting columns, and solenoid valves in the power distribution box. The electrical control system precisely controls each component; for example, the servo motor adjusts the angle of the centralized seeding box to meet the sowing needs of different locations, and the hydraulic lifting column controls the height of the centralized seeding box to ensure accurate insertion into the sand. This highly automated system reduces the need for manual intervention, greatly improves operational efficiency, and maintains stable performance even in complex terrain conditions.

[0016] High-pressure gas is used to blow seeds from the seed storage chute into the seeding discharge hole through an air pipe, and the timing of the seeds falling into the soil is precisely controlled by an electromagnetic valve. The high-pressure gas not only helps the seeds enter the seeding discharge hole smoothly, but also prevents the seeds from clogging, ensuring that each seeding point receives the appropriate amount of seeds. Compared with traditional manual or semi-automatic seeding methods, this method greatly improves the uniformity and accuracy of seeding, which helps to increase crop yield.

[0017] The design incorporates a swing arm and an arc-shaped positioning groove, allowing the centralized seeding box to rotate flexibly as needed. Meanwhile, the hydraulic lifting column ensures effective adaptation to sandy areas of varying depths. Through the design of the mechanical structure, the seeding device can operate flexibly in uneven or complex terrain, making it particularly suitable for operations in special geographical conditions such as high-altitude sandy areas. It can effectively overcome problems that traditional seeders struggle to handle, such as uneven terrain and loose soil. Attached Figure Description

[0027] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0028] This embodiment provides, for example Figures 1 to 5The device shown is a seeding device for high-altitude sandy areas, comprising a seeding cart 1, a power distribution box 2 mounted on the seeding cart 1, a seed box 5 mounted above the power distribution box 2, an upper frame plate 16 fixed between the power distribution box 2 and the seed box 5, a rocker arm 8 rotatably mounted on one end of the upper frame plate 16, and a centralized seeding box 10 mounted on the free end of the rocker arm 8 away from the upper frame plate 16 via a lifting component, the centralized seeding box 10 having multiple seed storage channels 23 inside, each seed storage channel 23 having multiple seed feeding holes 24 equidistantly arranged on the inner bottom wall of the inner bottom wall, each seed feeding hole 24 having a seed insertion tube 13 connected to the bottom of the centralized seeding box 10, and each seed insertion tube 13 having a seed insertion tip 22 integrally connected to the bottom end of the seed insertion tube 13 for insertion into the sandy area, the seed box 5 being connected to the centralized seeding box 10 via a transparent seed insertion tube 9. The seeds are transported to multiple sowing and storage chutes 23, from which they fall into each sowing feed hole 24 and sowing tube 13. Each sowing tip 22 and adjacent sowing tube 13 is equipped with a sowing solenoid valve 14. An air pump in the power distribution box 2 is connected to the multiple sowing and storage chutes 23 of the centralized sowing box 10 via an air pipe 25. High-pressure gas blows the seeds from the sowing and storage chutes 23 into the sowing feed holes 24. A lifting component drives the centralized sowing box 10 to descend, inserting the sowing tips 22 of each sowing tube 13 into the sand. Simultaneously, each sowing solenoid valve 14 is opened, allowing the seeds to fall from the sowing tips 22 into the soil. The sowing solenoid valve 14 is then quickly closed, completing one sowing cycle. Simultaneously, the swing arm 8 rotates the centralized sowing box 10, allowing sowing to be performed at different locations.

[0029] In this embodiment, each seeding hole 24 located on the bottom surface of the centralized seeding box 10 is fixed with a seeding connecting pipe 15, and the top end of each seeding tube 13 is integrally connected with an external threaded pipe 21, which is threadedly connected to the seeding connecting pipe 15. The threaded connection method ensures a stable connection between the seeding tube and the centralized seeding box, and also facilitates disassembly, maintenance, or replacement of seeding tubes of different specifications to meet different operational needs.

[0030] In this embodiment, the top surface of the centralized seeding box 10 is bolted with a detachable top plate 11, and the lifting component includes a hydraulic lifting column 12 installed on the top surface of the detachable top plate 11. The tail end of the hydraulic lifting column 12 is bolted to the bottom surface of the free end of the rocker arm 8.

[0031] In this embodiment, a seeding and feeding pipe 7 is connected through the outer wall of the seed box 5, and the seeding and feeding pipe 7 is sealed to the end of the transparent seeding pipe 9 away from the centralized seeding box 10.

[0032] In this embodiment, a semi-circular positioning plate 17 is welded to one side of the outer wall of the upper frame plate 16. An arc-shaped positioning groove 18 is provided inside the semi-circular positioning plate 17. An arc-shaped positioning slider 19 that can slide in the arc-shaped positioning groove 18 is welded to the bottom surface of the rocker arm 8.

[0033] In this embodiment, a servo motor 20 is fixed to the bottom surface of one end of the upper frame plate 16 near the semi-circular positioning plate 17. The output shaft of the servo motor 20 rotates through the upper frame plate 16 and is fixedly connected to one end of the rocker arm 8, so that the servo motor 20 drives the rocker arm 8 to rotate.

[0034] In this embodiment, a cover plate 6 is installed on the top surface of the seed box 5, and a handle is symmetrically installed on the top surface of the cover plate 6. A handrail 3 is installed at the end of the seeding cart 1 away from the seeding tube 13, and wheels 4 are installed on the bottom surface of the seeding cart 1.

[0035] In this embodiment, both the transparent seeding tube 9 and the air tube 25 are equipped with electromagnetic valves at the ends near the centralized seeding box 10. When it is necessary to open the channel of the transparent seeding tube 9 or the air tube 25, the corresponding electromagnetic valve is opened.

[0036] Working principle

[0037] This seeding device for high-altitude sandy areas loads seeds into a seed box 5. The top of the seed box has a cover 6, which can be opened via symmetrically installed handles for easy seed filling. Seeds are transported from the seed box 5 to a centralized seeding box 10 via a seeding feed pipe 7 connected to a transparent seeding pipe 9. During this process, the seeds are distributed into multiple seeding storage channels 23 within the centralized seeding box. An air pump in the power distribution box 2 supplies high-pressure gas to the centralized seeding box 10 via an air pipe 25. This high-pressure gas agitates the seeds in the seeding storage channels 23, causing them to fall into the seeding feed holes 24.

[0038] Servo motor 20 drives rocker arm 8 to rotate, adjusting the position of centralized seeding box 10 to ensure that seeding tube 13 can accurately reach the predetermined seeding position. At the same time, hydraulic lifting column 12 acts as a lifting component to control the height of centralized seeding box 10, allowing the seeding tip 22 to be inserted into the sand. When all preparations are completed, the solenoid valves, including the solenoid valve body 14 and the solenoid valves inside the transparent seeding tube 9 and air tube 25, are opened when needed, allowing seeds to enter the soil from the seeding hole 24 through the seeding tube 13 and the seeding tip 22. The solenoid valve body 14 is opened instantly, and the solenoid valve closes quickly after the seeds fall, completing one sowing operation.

[0039] After sowing is completed, the hydraulic lifting column 12 lifts the centralized sowing box 10 back to the initial height. The servo motor 20 can further adjust the angle or position of the centralized sowing box 10 to prepare for the next sowing point. The entire sowing cart 1 can be easily moved to the next working position via the handle 3 and wheels 4.
