[0012] In order to make the technical problems, technical solutions, and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0013] As Figures 1 to 3 shown, a deep water supplementing sowing device applicable to arid areas includes a tractor 1 and a seeder 2 connected to the tail of the tractor. The seeder 2 includes a frame 3, a sowing box 4, a furrow opener 5, and a soil covering roller 6. The bottom of the frame 3 is installed with traveling wheels 7 through a rotating shaft. A support frame 8 is installed on the frame 3, and a sowing box 4 is installed on the support frame 8. A seed metering device 9 is arranged inside the sowing box 4. The seed metering wheel of the seed metering device 9 is connected to the rotating shaft through a sprocket chain. The seed outlet of the seed metering device 9 is connected with a seed guiding pipe 10. A furrow opener 5 is also installed at the bottom of the frame 3. A water supplementing mechanism 12 is installed at the rear of the furrow opener 5. The water supplementing mechanism 12 is installed on the bottom connecting frame of the frame 3 through a central shaft 11. The outlet end of the seed guiding pipe 10 is located behind the water supplementing mechanism 12. The tail of the frame 3 is also connected with a soil covering roller 6 through a steel cable.

[0014] In the present invention, a furrow opener 5, a water replenishing mechanism 12 and a soil covering roller 6 are installed on a seeder 2. The water replenishing mechanism 12 is arranged between the furrow opener 5 and the soil covering roller 6, and the seed dropping point of a seed guiding tube 10 is located between the water replenishing mechanism 12 and the soil covering roller 6. When a tractor 1 drives the seeder 2 to move, the furrow opener 5 opens a furrow, and at the same time, the water replenishing mechanism 12 sprays water into the furrow. Seeds in a seed box 4 fall into the furrow through the seed guiding tube 10, and the soil covering roller 6 covers the seeds with soil. Precise water replenishment is carried out by the water replenishing mechanism 12, and the water can seep into the soil in time after the furrow is opened by the furrow opener, ensuring that the seeds have sufficient water for growth.

[0015] Among them, the water replenishing mechanism 12 includes a micro-pressure water tank 14, a high-pressure gas tank 15, a circular sealing wheel 16 and a water spraying pipe 17. The inside of the circular sealing wheel 16 is a hollow structure. An annular partition plate 18 is arranged inside the circular sealing wheel 16. A central shaft 11 penetrates through the circular sealing wheel 16, and the central shaft 11 and the circular sealing wheel 16 are connected by a rotary sealing structure 19. The central shaft 11 is a hollow shaft, and a water injection port 20 is arranged on the wall body of the central shaft 11 located inside the annular partition plate 18. One end of the central shaft 11 is closed, and a driven sprocket 21 is installed at the end. The driven sprocket 21 is connected to a rotating shaft by a chain. The other end of the central shaft 11 is connected to a water delivery pipe 23 through a rotary joint 22, and the water delivery pipe 23 is connected to the micro-pressure water tank 14. A high-pressure gas tank 15 is installed on the micro-pressure water tank 14, and the high-pressure gas tank 15 is connected to an air pump of the tractor 1. A plurality of water spraying pipes 17 are further arranged between the outside of the annular partition plate 18 and the circular sealing wheel 16. One end of the water spraying pipe 17 is communicated with the inside of the annular partition plate 18, and the other end extends to the outside of the circular sealing wheel 16, and a protective cover 24 is installed at the end. A control valve assembly is installed on the water spraying pipe 17. The water replenishing mechanism 12 replenishes water with micro-pressure. The high-pressure gas tank 15 is used to press the water in the micro-pressure water tank 14 into the inner chamber of the annular partition plate 18. When the water replenishing mechanism 12 rotates, the control valve assembly is opened in sequence to inject the water in the chamber of the annular partition plate 18 into the furrow.

[0016] The control valve assembly includes a solenoid valve 25, a counterweight 26, a contact sensor 27, and a support spring 28. The solenoid valve 25 is installed on the water spray pipe 17. The contact sensor 27 is installed on the solenoid valve 25. The support spring 28 and the counterweight 26 are also installed on the water spray pipe 17. The support spring 28 is located between the counterweight 26 and the solenoid valve 25. A storage battery 29 for supplying power to the solenoid valve and the contact sensor is also installed on the inner wall of the circular sealing wheel 16. A maintenance door 13 is also provided on the side wall of the circular sealing wheel 16. The control valve assembly adopts a cooperative structure of the solenoid valve 25, the counterweight 26, the contact sensor 27, and the support spring 28. The counterweight 26 is used to compress the support spring 28 to contact the contact sensor 27 to generate a trigger signal, controlling the solenoid valve 25 to open and realizing rapid water injection. In order to ensure the normal operation of the control valve assembly, the sum of the gravity and centrifugal force of the counterweight 26 is greater than the elastic force of the support spring 28. In this way, when the water spray pipe 17 rotates downward, when the sum of the gravity and centrifugal force of the counterweight 26 is equal to the elastic force of the support spring 28, the counterweight 26 gradually contacts the contact sensor 27, and the solenoid valve 25 opens to start injecting water. When the water spray pipe 17 rotates upward from the lowest point, when the sum of the gravity and centrifugal force of the counterweight 26 is equal to the elastic force of the support spring 28, the counterweight 26 gradually separates from the contact sensor 27, and the solenoid valve 25 closes, and the water injection is completed. The whole process can water the trench as the tractor moves. The solenoid valve 25 and the contact sensor 27 are powered by the storage battery 29. The storage battery 29 is installed on the inner wall of the circular sealing wheel 16. A maintenance door is provided on the side of the circular sealing wheel 16, and the storage battery and the solenoid valve can be maintained.

[0017] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the scope of the present invention.
