Detailed Embodiment
[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0020] Embodiment 1 As Figures 1 - 8 shown, a furrowing and film mulching device for melon planting includes an installation frame 1. A scraping soil groove 3 is fixedly connected to the lower part of the installation frame 1. A soil dividing plate 18 is fixedly connected inside the scraping soil groove 3. One end of the soil dividing plate 18 is fixedly connected to a soil discharging groove 4. An adjusting mechanism is arranged inside the soil discharging groove 4. The adjusting mechanism includes a transmission groove 20 fixedly connected to the upper part of the soil discharging groove 4. A third motor 21 is arranged at one end of the transmission groove 20. A threaded rod 22 is arranged at the output end of the third motor 21. The threaded rod 22 is threadedly connected to a transmission part 23. The transmission part 23 is fixedly connected to a transmission rod 24. The transmission rod 24 is slidably connected to the soil discharging groove 4. One end of the transmission rod 24 away from the transmission part 23 is rotatably connected to a connecting part 25. The connecting part 25 is rotatably connected to an adjusting plate 19.
[0021] A film mulching mechanism is arranged on the upper part of the installation frame 1. The film mulching mechanism includes a cylinder 7 arranged on the upper part of the installation frame 1. An installation plate 26 is arranged at the output end of the cylinder 7. A film mulching roller 5 and a pressing roller 6 are rotatably connected to the lower part of the installation plate 26. After furrowing, the soil accumulates on both sides of the top of the furrow. The soil is shoveled into the scraping soil groove 3 through the scraping soil groove 3. Then the soil is divided into the soil discharging groove 4 through the soil dividing plate 18. Next, the film mulching roller 5 arranged at the lower part of the soil discharging groove 4 mulches the top of the furrow. And the soil discharged from the soil discharging groove 4 just covers both sides of the sealing film. The pressing roller 6 presses and fixes the sealing film. Moreover, by starting the third motor 21 to drive the transmission rod 24 to move, the movement of the transmission rod 24 drives the connecting part 25 to rotate, and then drives the adjusting plate 19 to rotate, adjusting the amount of soil discharged from the soil discharging groove 4 to ensure the uniformity of soil coverage. The bottoms of both the film mulching roller 5 and the pressing roller 6 are located in the same plane. Wheels are arranged at the bottom of the installation frame 1.
[0022] In this embodiment, after the trench is dug, soil is piled up at both ends of the trench top. When the mounting frame 1 moves, the soil at the trench top can be scraped up by the soil scraping groove 3 at the bottom and thus brought into the soil scraping groove 3. After the soil enters the soil scraping groove 3, the soil can be guided into the soil discharge grooves 4 on both sides through the soil dividing plate 18. After the soil is scraped up, the trench top is leveled. At this time, the trench top can be effectively covered with a film by the film covering roller 5. Moreover, since the soil has been scraped into the soil scraping groove 3, the sealing film can be flatly covered on the trench top, and the film covering effect is better. After the film covering is completed, the soil discharged from the upper part of the soil discharge groove 4 can cover both sides of the sealing film, thereby fixing the sealing film. After the soil covers the sealing film, the soil covering both sides of the sealing film can be compacted by the pressing roller 6, further improving the covering effect of the sealing film. And the cylinder 7 can drive the mounting plate 26 to move, thereby finely adjusting the positions of the film covering roller 5 and the pressing roller 6 to ensure that the film covering roller 5 can effectively contact the ground.
[0023] During the process of discharging soil from the soil discharge groove 4, by starting the third motor 21, the threaded rod 22 can be driven to rotate. The rotation of the threaded rod 22 can drive the moving member 23 connected by thread to move, and the movement of the moving member 23 can drive the transmission rod 24 fixedly connected thereto to move. By the movement of the transmission rod 24, the connecting member 25 connected by rotation can be driven to rotate, and the rotation of the connecting member 25 can drive the adjusting plate 19 connected by rotation to rotate, thereby adjusting the soil discharge amount of the soil discharge groove 4 to ensure that the soil discharged from the soil discharge groove 4 can evenly cover both sides of the sealing film.
[0024] Embodiment Two As Figures 1 - 8 shown, a lifting mechanism is fixedly connected to the front end of the mounting frame 1, and a trench digging housing 11 is fixedly connected to the bottom of the lifting mechanism. A trench digging mechanism is arranged inside the trench digging housing 11. The lifting mechanism includes an adjusting housing 8 fixedly connected to the upper part of the mounting frame 1. A second motor 12 is arranged inside the adjusting housing 8, and a lifting assembly is arranged at the output end of the second motor 12. The lifting assembly includes a worm 13 arranged at the output end of the second motor 12. The worm 13 is rotatably connected to the adjusting housing 8, and the worm 13 is meshed with a worm gear 14. The worm gear 14 is rotatably connected to the adjusting housing 8. A transmission gear 15 is fixedly connected to the side of the worm gear 14 away from the adjusting housing 8, and the transmission gear 15 is meshed with a transmission rack 16. The bottom of the transmission rack 16 is fixedly connected to the trench digging housing 11.
[0025] A limiting groove 27 is fixedly connected inside the adjusting housing 8, and the transmission rack 16 is slidably connected inside the limiting groove 27. The trench digging mechanism includes a first motor 9 arranged on one side of the trench digging housing 11, and a trench digging plow 10 is arranged at the output end of the first motor 9. The trench digging plow 10 is rotatably connected to the trench digging housing 11. A seed box 2 is fixedly connected to the upper part of the mounting frame 1, and an electric valve 17 is fixedly connected to the bottom of the seed box 2. The number of the electric valves 17 is two, and an equalizing wheel 28 is rotatably connected inside the electric valve 17.
[0026] In this embodiment, starting the first motor 9 can drive the trench-opening plow blade 10 to rotate. By rotating the trench-opening plow blade 10, the soil can be turned up to form a trench. During the trenching process, starting the second motor 12 can drive the worm 13 to rotate. The rotation of the worm 13 drives the meshing-connected worm wheel 14 to rotate. The rotation of the worm wheel 14 can drive the fixedly-connected transmission gear 15 to rotate. The rotation of the transmission gear 15 can drive the meshing-connected transmission rack 16 to move. When the transmission rack 16 moves, the externally sliding-connected limit groove 27 can effectively ensure the stability of the transmission rack 16 during movement. The movement of the transmission rack 16 can drive the trench-opening housing 11 to move up and down, and the movement of the trench-opening housing 11 can adjust the height of the trench-opening plow blade 10, thereby adjusting the trench depth and improving the use effect of the device. After the trenching is completed, the electric valve 17 can control the melon seeds in the seed box 2 to fall into the trench. The evenly-distributing wheel 28 rotatably connected inside the electric valve 17 can make the melon seeds fall evenly, improving the sowing effect.
