Description

Technical Field

[0001] This invention relates to the field of plant fertilization spraying technology, and in particular to a high-precision fertilizer spraying device for wheat cultivation. Background Technology

[0002] Wheat is one of the world's most important food crops. It belongs to the Poaceae family and is one of the crops with the largest planting area and yield in the world. It is widely used for human food, animal feed and industrial purposes. Wheat cultivation is not only an important pillar of the agricultural economy, but also occupies a core position in global food production. Wheat needs to be fertilized during cultivation.

[0003] Current fertilizer spraying devices for wheat cultivation, while capable of spraying fertilizer and water onto wheat, lack the ability to automatically adjust the spraying height and mist size based on windy conditions. This results in insufficient fertilization effectiveness and reduced overall efficiency. Therefore, there is an urgent need to design a high-precision fertilizer spraying device for wheat cultivation. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art, and to propose a high-precision fertilizer spraying device for wheat planting.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A high-precision fertilizer spraying device for wheat cultivation includes a housing, on which a traction block for connecting to a traction machine is installed, and a fertilizer / water inlet is also installed on the housing. It further includes: Triangular blocks are placed on top of the box and can rotate with the wind direction; The pipe body is horizontally set on the side of the box, and multiple spray pipes are installed in a straight line at the bottom of the pipe body. Each spray pipe has a first screen plate fixed at the bottom, and a second screen plate is rotatably installed on the top of each first screen plate. The misalignment of the first screen plate and the second screen plate can change the water outlet diameter of the spray pipe. Two hoses are connected to the side of the box body and installed on the surface of the pipe body. Two liquid pumps connected to the corresponding hoses are installed inside the box body. The drive component is mounted on the housing and is used to drive the pipe to move up and down by wind speed. This changes the height of the nozzle above the wheat and prevents the nozzle from being too high in windy weather, which could cause fertilizer and water to drift away. The transformation component is installed on the housing and is used to change the position of the second network disk, thereby causing the first network disk and the second network disk to be misaligned.

[0006] As a further technical solution of the present invention, the transformation component includes: a box body, there are multiple boxes body, the multiple boxes body are uniformly fixedly installed inside multiple nozzles, and a fixing rod is rotatably installed at the bottom of the box body, the end of the fixing rod is fixedly installed at the center of the top surface of the second mesh disk, for supporting and limiting the fixing rod.

[0007] As a further technical solution of the present invention, a worm gear and a worm are rotatably installed inside the housing. The center of the end of the worm gear is fixedly installed at the center of the top of the fixed rod via a connecting shaft.

A limit plate is vertically fixedly installed on one corner of the top of the triangular block, and a fan blade is rotatably installed on the side of the limit plate. Since the limit plate and fan blade are installed as counterweights on one corner of the triangular block, when the external wind blows the triangular block to rotate, the corner of the triangular block with counterweights will face the wind direction, which will promote the fan blade to rotate at its maximum performance.

[0011] As a further technical solution of the present invention, a first bevel gear is fixedly installed on the top of the column, and a second bevel gear is fixedly installed on the end face of the fan blade.

An annular groove is opened on the top of the first sleeve plate, and a ring is rotatably installed inside the annular groove. Multiple first rotating rods are rotatably installed on the top of the ring. A counterweight is rotatably installed on the top of each first rotating rod, and a second rotating rod is rotatably installed on the side of each counterweight. The tops of the multiple second rotating rods are rotatably installed on the ground of the second sleeve plate, which is used to drive the counterweight to rotate through the second sleeve plate, and drive the first sleeve plate to move vertically through the centrifugal force of the counterweight.

[0013] As a further technical solution of the present invention, an L-shaped connecting rod is fixedly installed on the surface of the first set of discs, and a movable rod is rotatably installed at the horizontal end of the L-shaped connecting rod. A horizontally arranged rack is rotatably installed at the other end of the movable rod.

The first gear meshes with the rack. A first telescopic rod is horizontally fixedly installed on the side of the housing. The fixed end and the telescopic end of the first telescopic rod are slidably connected by a spline. A fixing plate is fixedly installed on one end of the first telescopic rod, and one side of the fixing plate is fixedly installed on the end face of the rack to limit the rack and ensure that the rack can move horizontally stably.

[0015] The beneficial effects of this invention are as follows: This invention, through the configuration of the drive and transformation components, can reduce the interference of wind on the spraying of fertilizer and water, ensuring the uniformity of the spraying. Furthermore, it can adjust the height of the pipe and the diameter of the fertilizer and water outlet in real time according to the wind strength, so that there is an optimal height and optimal outlet diameter during spraying, ensuring the uniformity of fertilizer and water spraying and the accuracy of fertilization, thereby improving the effectiveness of the equipment.

A limit plate 30 is vertically and fixedly mounted on one corner of the top of the triangular block 7, and a fan blade 8 is rotatably mounted on the side of the limit plate 30. Since the limit plate 30 and the fan blade 8 are installed as counterweights on one corner of the triangular block 7, when the external wind blows the triangular block 7 to rotate, the corner of the triangular block 7 with counterweights will face the wind direction, causing the fan blade 8 to rotate at its maximum performance.

[0026] Please see the appendix Figure 1 -Appendix Figure 7 In a preferred embodiment, a first bevel gear 21 is fixedly installed on the top of the column 20, and a second bevel gear 22 is fixedly installed on the end face of the fan blade 8.

[0027] Please see the appendix Figure 1 -Appendix Figure 8 In a preferred embodiment, a second sleeve plate is fixedly sleeved on the surface of the column 20, and a first sleeve plate 15 is slidably sleeved on the surface of the column 20. An annular groove is opened on the top of the first sleeve plate 15, and a ring 16 is rotatably installed inside the annular groove. Multiple first rotating rods 17 are rotatably installed on the top of the ring 16 in an annular shape. A counterweight 18 is rotatably installed on the top of each first rotating rod 17. A second rotating rod 19 is rotatably installed on the side of each counterweight 18. The tops of the multiple second rotating rods 19 are rotatably installed on the ground of the second sleeve plate, which is used to drive the counterweight 18 to rotate through the second sleeve plate, and drive the first sleeve plate 15 to move vertically through the centrifugal force of the counterweight 18.

[0028] Please see the appendix Figure 3 -Appendix Figure 8 In a preferred embodiment, an L-shaped connecting rod 14 is fixedly mounted on the surface of the first sleeve 15, and a movable rod 12 is rotatably mounted on the horizontal end of the L-shaped connecting rod 14. A horizontally arranged rack 11 is rotatably mounted on the other end of the movable rod 12. The L-shaped connecting rod 14 moves with the first sleeve 15 and is used to drive the rack 11 to move horizontally through the movable rod 12.

[0029] Please see the appendix Figure 1 -Appendix Figure 8 In a preferred embodiment, a first gear 13 is rotatably mounted on the top of the housing 1. The bottom of the first gear 13 is fixedly mounted to the center of the top of the lead screw 9 via a connecting shaft. The first gear 13 meshes with the rack 11. A first telescopic rod 10 is horizontally fixedly mounted on the side of the housing 1. The fixed end and the telescopic end of the first telescopic rod 10 are slidably connected by a spline. A fixing plate is fixedly mounted on one end of the first telescopic rod 10. One side of the fixing plate is fixedly mounted on the end face of the rack 11 to limit the rack 11 and ensure that the rack 11 can move horizontally stably.

[0030] Fertilizer water is added into the box 1 through the feed inlet. Then, the box 1 is installed on the traction machine through the traction block. The traction machine then moves the box 1. The traction machine moves the box 1 and its connecting parts together in the wheat field. When spraying fertilizer water. In windless weather, the fan blade 8 needs to overcome the friction between the components and the gravity of the tube 2 to rotate, so that the fan blade 8 will not rotate. Furthermore, the tube 2 will maintain the original height (higher height) and the original aperture (smaller aperture) to spray fertilizer and water, ensuring the uniformity of fertilizer and water spraying. When there is wind, the wind will cause the triangular block 7 to rotate. Since the limiting plate 30 is installed at one corner of the triangular block 7, the triangular block 7 will rotate until the corner where the limiting plate 30 is located faces the wind. Then, the fan blade 8 will rotate due to the wind. The rotation of the fan blade 8 will drive the second bevel gear 22 to rotate, the rotation of the second bevel gear 22 will drive the first bevel gear 21 to rotate, the rotation of the first bevel gear 21 will drive the column 20 to rotate, the rotation of the column 20 will drive the second disc to rotate, and the rotation of the second disc will drive the second rotating rod 19, the counterweight 18, the first rotating rod 17, and the ring 1. When the counterweight 18 rotates, it will move away from the column 20 due to centrifugal force. This movement of the counterweight 18 will cause the ring 16 and the first sleeve plate 15 to move upwards. The upward movement of the first sleeve plate 15 will cause the L-shaped connecting rod 14 to move upwards. The movement of the L-shaped connecting rod 14 will cause the movable rod 12 to move. The movement of the movable rod 12 will cause the rack 11 to move horizontally (due to the limiting effect of the first telescopic rod 10). The movement of the rack 11 will cause the first gear 13 to rotate. The rotation of the first gear 13 will cause the lead screw 9 to rotate. The rotation of the lead screw 9 will cause the sleeve plate 6 to move. The movement of the connecting rod 5 causes the pipe body 2 and its connecting components to move downwards together. Due to the limiting effect of the second telescopic rod 23, when the connecting rod 5 moves downwards with the pipe body 2, the length of the second telescopic rod 23 changes and drives the connecting rod 5 to rotate. The rotation of the connecting rod 5 drives the worm gear 29 to rotate, the rotation of the worm gear 29 drives the worm wheel 28 to rotate, the rotation of the worm wheel 28 drives the fixed rod 26 to rotate, and the rotation of the fixed rod 26 drives the second mesh disk 25 to rotate. This allows the aperture formed between the first mesh disk 24 and the second mesh disk 25 to increase, thus enabling fertilizer spraying in windy weather. When spraying water, lowering the height of the spray pipe 4 and increasing the diameter of the fertilizer outlet (reducing the spraying speed of the fertilizer and water, avoiding the situation where the fertilizer and water spray too quickly due to the lowered spray pipe 4, causing the wheat to be knocked over) can reduce the interference of wind on the fertilizer and water spraying, ensuring the uniformity of fertilizer and water spraying. Furthermore, the height of the pipe body 2 and the diameter of the fertilizer and water outlet can be adjusted in real time according to the wind strength, so that there is an optimal height and optimal outlet diameter during spraying, ensuring the uniformity of fertilizer and water spraying, thereby improving the use effect of the equipment.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
