[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0024] The following gives specific embodiments.
[0025] As Figures 1 to 4 shown, a wheat planting and fertilizing device described in an embodiment of the present utility model includes a water pipe 1; the top end of the water pipe 1 is rotatably connected to a rotating pipe 12; a plurality of spray heads 13 are fixedly connected to the middle of the rotating pipe 12; the top end of the rotating pipe 12 is slidably connected to a shaft column 14; the bottom end of the shaft column 14 is fixedly connected to a bearing plate 15; the top end of the shaft column 14 is fixedly connected to a protective cover 16; the protective cover 16 surrounds the plurality of spray heads 13; during operation, the water and fertilizer liquid is pumped into the inside of the water pipe 1 by a liquid pump, and then the inside of the water pipe 1 and the rotating pipe 12 are filled with hydraulic pressure. Then, the bottom of the bearing plate 15 is squeezed by the liquid to drive the shaft column 14 and the protective cover 16 to rise. After the protective cover 16 rises, the protective cover 16 no longer blocks the output ends of the plurality of spray heads 13, so that the water and fertilizer liquid inside the rotating pipe 12 can fall on the wheat crops and land around the water pipe 1 after being sprayed out through the plurality of spray heads 13. After the water supply is stopped, the water pressure inside the rotating pipe 12 decreases, and the protective cover 16 will gradually slide down and surround the plurality of spray heads 13 inside, thereby reducing the occurrence of the plurality of spray heads 13 being blocked by sand and dust. Through the above structure, after the water and fertilizer spraying is completed, the plurality of spray heads 13 can be isolated and protected, and the occurrence of the plurality of spray heads 13 being blocked by sand and dust can be reduced.
[0026] As Figures 1 to 4As shown, a fixing rod 2 is fixedly connected to the middle of the spray head 13; a ring plate 21 is fixedly connected to the middle of the spray head 13; the ring plate 21 is located between the fixing rod 2 and the output end of the rotating pipe 12; an elastic cord 22 is fixedly connected to the side wall of the fixing rod 2; the elastic cord 22 passes through the middle of the ring plate 21 and the other end of the elastic cord 22 is fixedly connected to a blocking ball 23; the diameter of the blocking ball 23 is larger than the inner diameter of the ring plate 21; the plurality of elastic cords 22 are divided into two groups according to the elastic size, one group has a larger elasticity and the other group has a smaller elasticity, and the two groups of elastic cords 22 are arranged at intervals and staggered inside the plurality of spray heads 13; during operation, when the water pressure is sufficient, the water flow is sufficient to wash away the plurality of blocking balls 23, and then the water and fertilizer will be sprayed through the plurality of spray heads 13. When the water pressure is low, the blocking ball 23 connected by the high-elasticity elastic cord 22 is difficult to be washed away by the water flow, while the blocking ball 23 connected by the low-elasticity elastic cord 22 can be washed away by the water flow, so that the water and fertilizer can only be sprayed out from some of the spray heads 13. By reducing the number of outlets of the water and fertilizer, the situation of the spraying distance of the water and fertilizer decreasing is reduced, and thus the situation that some wheat cannot be covered by the water and fertilizer when the water pressure is low is reduced. Through the above structure, different numbers of spray heads 13 can be adaptively opened according to different water pressures, and the situation of the coverage area decreasing caused by the spraying distance of the water and fertilizer liquid decreasing can be reduced.
[0027] As Figures 1 to 3 shown, a first rubber ring 3 is fixedly connected to the inner top of the rotating pipe 12; a second rubber ring 31 is fixedly connected to the middle of the bottom end of the shaft column 14; during operation, when the shaft column 14 rises due to the water pressure inside the rotating pipe 12, the second rubber ring 31 and the first rubber ring 3 will come into contact with each other and be tightly combined, reducing the occurrence of liquid passing through, and further reducing the occurrence of the water pressure inside the rotating pipe 12 decreasing, and further reducing the occurrence of the spraying distance of the water and fertilizer of the plurality of spray heads 13 decreasing.
[0028] As Figures 1 to 2 shown, a plurality of impellers 4 are fixedly connected to the middle of the rotating pipe 12; the plurality of impellers 4 are arranged in a circumferential array below the spray head 13; during operation, when the water and fertilizer liquid is sprayed out through the plurality of spray heads 13, the water and fertilizer liquid inside the rotating pipe 12 will continuously flow through the plurality of impellers 4, thereby driving the plurality of impellers 4 and the rotating pipe 12 to rotate, so that the liquid sprayed out by the plurality of spray heads 13 can fall more evenly on the wheat crops and the land, thereby improving the fertilization effect.
[0029] As Figures 1 to 3As shown, a spring 5 is fixedly connected to the inner top of the rotating pipe 12; the bottom end of the spring 5 is arranged lower than the bottom of the first rubber ring 3; during operation, when applying water and fertilizer, the bearing plate 15 will contact the bottom end of the spring 5 and squeeze the spring 5 after rising. After the fertilization is completed, the bearing plate 15 is no longer squeezed by the water and liquid. At this time, the bearing plate 15 will be bounced off by the spring 5, reducing the situation that it is difficult for the protective cover 16 to fall due to the tight combination between the second rubber ring 31 and the first rubber ring 3, and protecting the nozzle 13.
[0030] As Figures 1 to 2 shown, a circular plate 6 is fixedly connected to the middle of the water pipe 1; the circular plate 6 is attached to the bottom of the protective cover 16; during operation, after the application of water and fertilizer is completed, the protective cover 16 will fall to the top of the circular plate 6, making it difficult for external impurities to enter through the protective cover 16 and the circular plate 6, and further reducing the situation that the nozzle 13 is blocked by sand and dust.
[0031] As Figures 1 to 2 shown, a surrounding plate 7 is fixedly connected to the top of the circular plate 6; the diameter of the surrounding plate 7 is larger than the diameter of the circular plate 6; during operation, when fertilizing, some water and fertilizer liquid will first be sprayed on the inner side wall of the protective cover 16 and fall on the circular plate 6. These liquids will be blocked by the surrounding plate 7 and accumulate on the circular plate 6. Therefore, when fertilizing, the situation that crawling insects enter the protection area of the protective cover 16 along the circular plate 6 is reduced. Thus, after the fertilization stops, the situation that insects are trapped inside the protective cover 16 and then crawl into the inside of the nozzle 13 to cause blockage is reduced.
[0032] Working principle: The water and fertilizer liquid is pumped into the interior of the water pipe 1 by a liquid pump, and then the interiors of the water pipe 1 and the rotating pipe 12 are filled with hydraulic pressure. Then, the bottom of the bearing plate 15 is squeezed by the liquid, driving the shaft column 14 and the protective cover 16 to rise. After the protective cover 16 rises, the protective cover 16 no longer blocks the output ends of the multiple nozzles 13, enabling the water and fertilizer liquid inside the rotating pipe 12 to fall on the wheat crops and the land around the water pipe 1 after being sprayed through the multiple nozzles 13. After the water supply stops, the water pressure inside the rotating pipe 12 decreases, and the protective cover 16 gradually slides down, surrounding the multiple nozzles 13 inside, thereby reducing the occurrence of the multiple nozzles 13 being blocked by sand and dust. When the water pressure is sufficient, the water flow is sufficient to wash open the multiple blocking balls 23, and then the water and fertilizer will be sprayed through the multiple nozzles 13. When the water pressure is low, the blocking balls 23 connected by the high-elasticity elastic ropes 22 are difficult to be washed open by the water flow, while the blocking balls 23 connected by the low-elasticity elastic ropes 22 can be washed open by the water flow, so that the water and fertilizer can only be sprayed out from some of the nozzles 13. By reducing the number of outlets of the water and fertilizer, the situation of the spraying distance of the water and fertilizer decreasing is reduced, and thus the situation that some wheat cannot be covered by the water and fertilizer when the water pressure is low is reduced. When the shaft column 14 rises due to the water pressure inside the rotating pipe 12, the second rubber ring 31 and the first rubber ring 3 will come into contact with each other and tightly combine, reducing the occurrence of liquid passing through, and further reducing the occurrence of the water pressure inside the rotating pipe 12 decreasing. When the water and fertilizer liquid is sprayed out through the multiple nozzles 13, the water and fertilizer liquid inside the rotating pipe 12 continuously flows through the multiple impellers 4, thereby driving the multiple impellers 4 and the rotating pipe 12 to rotate, so that the liquid sprayed out by the multiple nozzles 13 can fall more evenly on the wheat crops and the land. When applying water and fertilizer, the bearing plate 15 will come into contact with the bottom end of the spring 5 and squeeze the spring 5 after rising. After the fertilization is completed, the bearing plate 15 is no longer squeezed by the water liquid. At this time, the bearing plate 15 will be bounced off by the spring 5. When applying fertilizer, some of the water and fertilizer liquid will first be sprayed on the inner side wall of the protective cover 16 and fall on the circular plate 6. These liquids will be blocked by the surrounding plate 7 and accumulate on the circular plate 6, thereby reducing the occurrence of crawling insects entering the protection area of the protective cover 16 along the circular plate 6 when applying fertilizer.
