[0001] The invention relates to the technical field of agricultural machinery, in particular to a device for precision sowing of biological fertilizer and seeds in the same hole. Background Art

[0002] In modern agricultural practice, precision sowing and fertilization are one of the important links to ensure crop yield and quality. Traditional seed and fertilizer seeders mostly adopt a mechanical design, and their key components include seed-seeders, fertilizer-seeders, furrow openers, seed-seeding pipes, fertilizer-delivery pipes, and travel wheels. The seed-seeder is pulled forward by a traction mechanism, and the travel wheels drive the entire seed-seeder to move. In this process, the travel wheels are connected to the seed-seeder and fertilizer-seeder through chains or belts, so that they rotate with the rotation of the travel wheels. The seed-seeder takes the seeds out of the seed box by rotation and sends them to the furrows opened by the furrow opener through the seed-seeding pipe. At the same time, the fertilizer-seeder also releases fertilizer according to the set ratio, so that it falls into the furrow together with the seeds.

[0003] However, although the traditional mechanical seed and fertilizer seeder can meet the needs of agricultural production to a certain extent, it still faces some challenges in practical application. First, due to the wear of the chain or belt after long-term operation, the synchronization of seed and fertilizer in the traditional seed and fertilizer seeder is poor, which in turn affects the growth effect of crops; secondly, for biological organic fertilizers that require precise control of the application amount, especially high-value biological fertilizers, traditional equipment is difficult to achieve fine control, which easily leads to fertilizer waste, which undoubtedly increases the cost of agricultural production.

[0023] In the present invention, the seed metering device 2, the seed input pipe 3, and the collecting bin 4 constitute the material transmission path of the seeds from the seed box 1 to the distribution bin 9; the fertilizer metering device 6, the fertilizer hose 7, the bacterial fertilizer input pipe 8, and the collecting bin 4 constitute the material transmission path of the biological bacterial fertilizer from the bacterial fertilizer box 5 to the distribution bin 9.

[0024] The seed input pipe 3 and the fertilizer input pipe 8 at the upper end of the collecting bin 4 are respectively used to receive the seeds discharged by the seed metering device 2 and the biological fertilizer transported by the fertilizer hose 7, and allow the seeds and the biological fertilizer to enter the seed fertilizer trough formed by the baffle 17 and the inner wall of the distribution bin 9; the discharge pipe 10 arranged at the lower end of the distribution bin 9 is convenient for delivering the mixed seeds and biological fertilizer into the seed holes opened by the furrow opener 12. Since the distance from the discharge of seeds and biological fertilizers to the entry into the soil is very short, the possibility of loss or deviation of seeds and biological fertilizers from the predetermined position during the transmission process is reduced. This design ensures that seeds and biological fertilizers can be accurately put into the seed holes opened by the furrow opener 12, thereby improving the accuracy of sowing.

[0025] In the present invention, the distribution bin 9, the frame connecting fixing plate 11, the motor bin 13, the motor 14, the cam 15, the baffle shaft 16, the baffle 17, and the reset spring 18 together constitute a precise distribution mechanism for controlling the delivery process of seeds and biological fertilizers. Through the instructions of the controller, the motor 14 drives the cam 15 to rotate, and then drives the baffle shaft 16 to rotate by driving the cam 15, so as to realize the precise control of the baffle 17 and the distribution bin 9 from the closed state to the open state, and the reset spring 18 ensures the automatic recovery of the baffle 17 and the distribution bin 9 from the open state to the closed state. This process ensures that the seeds and biological fertilizer can accurately fall into the predetermined position each time sowing, realizes the precise positioning of seeds and fertilizers, and ensures that the two enter the seed hole synchronously, which is beneficial to the growth and development of crops; the baffle 17 is a shovel-shaped one-piece design, which reduces the number of mechanical connection points, reduces complexity and potential failure points, is not only convenient for cleaning and maintenance, but also improves the stability and life of long-term use. At the same time, it has better sealing and more convenient control, which effectively improves the speed and efficiency of sowing. In addition, the one-piece design can better adapt to compact space layout, making the entire device more miniaturized.

[0026] The seed input pipe 3 is provided with a seeding sensor 19, and the seeding sensor 19 is electrically connected to the seeding device 2 and the controller respectively.

[0027] The seed metering device 2 is an electrically driven air suction type seed metering disc, and the motor of the electrically driven air suction type seed metering disc is electrically connected to the controller.

[0028] The fertilizer discharger 6 is an electric-driven fertilizer discharger, and the controller is electrically connected to the motor of the electric-driven fertilizer discharger and the flow sensor of the electric-driven fertilizer discharger respectively.

[0029] The electric-driven air-suction seed tray and the electric-driven fertilizer dispenser can accurately control the discharge amount of seeds and biological fertilizers, further solving the problem of poor synchronization between seeds and fertilizers caused by chain or belt wear in traditional mechanical equipment. At the same time, through the precise control of the amount of biological fertilizer used, the use of biological fertilizers is significantly reduced, reducing agricultural production costs.

[0030] The furrow opener 12 is a shovel-type furrow opener.

[0031] The controller is a single chip microcomputer.

[0032] When in use, first put the seeds into the seed box 1, put the biological fertilizer into the fertilizer box 5, and connect the shovel-type furrow opener to the tractor, and then the tractor pulls the sowing device forward. At this time, the baffle 17 and the distribution bin 9 remain in a closed state, the controller starts the electric-driven air-suction seeding disc and sends a seed through the seed input pipe 3 and the collection bin 4 into the seed fertilizer tank in the distribution bin 9. At the same time, the controller starts the electric-driven fertilizer discharger and sends a set amount of biological fertilizer through the fertilizer hose 7, the fertilizer input pipe 8 and the collection bin 4 into the seed fertilizer tank in the distribution bin 9. When the sowing device reaches the seed hole, the controller starts the motor 14, the output shaft of the motor 14 rotates and drives the cam 15 to rotate, and the protrusion of the cam 15 gradually approaches and pushes the end of the baffle shaft 16 to make it The cam 15 rotates, and the baffle shaft 16 rotates while driving the baffle 17 to rotate and open toward the outside of the bottom end of the distribution bin 9. At this time, the seeds and biological fertilizers in the seed fertilizer groove are accurately put into the seed hole through the discharge pipe 10. The cam 15 continues to rotate, and its protrusion gradually leaves the baffle shaft 16, and no longer applies thrust to the baffle shaft 16. In the absence of external force, the restoring force of the reset spring 18 pulls the baffle shaft 16 back to its original position, so that the baffle 17 and the distribution bin 9 are closed again, preparing for the next sowing, thereby completing the use of the sowing device; it overcomes the problems of the existing mechanical seed and fertilizer same-hole seeder, such as poor synchronization of seed and fertilizer due to chain or belt wear after long-term operation, and inability to accurately control the amount of biological fertilizer, resulting in waste.

[0033] During the specific implementation process, the sowing device is close to the ground, so that it can more directly and stably place seeds and biological fertilizers into the seed holes. This method helps to achieve higher sowing accuracy.
