Description

Technical Field

[0001] This invention relates to the field of agricultural robot technology, and in particular to a simplified intelligent fertilization robot for dryland corn. Background Technology

[0002] Dryland maize refers to maize varieties that grow in dry land without irrigation. Its cultivation covers many regions of my country, including the Songliao Plain in Northeast China, the Huang-Huai-Hai Plain in North China, the Loess Plateau in Northwest China, and the mountainous and hilly areas in Southwest China. It is an important component of agricultural production in these regions and holds a crucial position. Dryland maize is not only an important food source, but its kernels are also rich in nutrients such as starch, protein, and fat, making it an essential part of human diet. These regions generally face problems such as water scarcity and uneven soil fertility. To ensure the normal growth of maize, regular fertilization is necessary to provide it with sufficient nutrients.

[0003] In existing technologies, fertilization of dryland corn is often carried out manually using spray fertilization devices. However, for large-scale corn fertilization, manual fertilization is not only labor-intensive, but also poses a significant health risk due to prolonged exposure to the fertilization environment. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a simplified intelligent fertilization robot for dryland corn.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A simplified intelligent fertilization robot for dryland corn includes a chassis, a servo motor fixedly connected to the upper surface of the chassis via a bracket, an output shaft of the servo motor fixedly connected to a machine shaft, a first bevel gear fixedly connected to the machine shaft, a guard plate fixedly connected to the lower surface of the chassis, and a fertilizer box fixedly connected to the upper surface of the chassis. A spraying mechanism is provided at the chassis. The spraying mechanism consists of a drive assembly and a spraying assembly. The drive assembly includes a rotating shaft, which is rotatably connected to the chassis through a bearing. A rotating block is fixedly connected to the rotating shaft. The spraying assembly includes a sliding sleeve, which is fixedly connected to the lower surface of the chassis. A sliding column is slidably and sealingly connected to the sliding sleeve. A drive plate is fixedly connected to the side wall of the sliding column on the outer side of the sliding sleeve. The chassis is equipped with a walking mechanism, which includes two axles. The axles are rotatably connected to the guard plate through bearings.

[0006] Furthermore, the drive assembly also includes a second bevel gear, which is fixedly connected to the end of the rotating shaft away from the rotating block. The second bevel gear meshes with the first bevel gear. The rotating block is threadedly connected to a screw, and the end of the screw located outside the rotating block is rotatably connected to a top block via a bearing. The top block abuts against the drive plate.

[0007] Furthermore, the fertilizer box, chassis, and sliding sleeve are all connected by a first pipe, which connects the fertilizer box to the sliding sleeve. Two fixing blocks are fixedly connected to the upper surface of the chassis. The fixing blocks are hollow. The fixing blocks, guard plate, and sliding sleeve are all connected by a third pipe, which connects the fixing blocks to the sliding sleeve. A second pipe is fixedly connected to the sidewalls of the two fixing blocks on opposite sides. A nozzle is fixedly connected to one end of the second pipe outside the fixing block. Multiple springs are fixedly connected between the drive plate and the sliding column.

[0008] Furthermore, the walking mechanism also includes a third bevel gear, which is fixedly connected to the lower surface of the rotating block. A fourth bevel gear is fixedly connected to one of the wheel axles, and the fourth bevel gear meshes with the third bevel gear. Both ends of the wheel axle are fixedly connected to walking wheels.

[0009] Furthermore, the rotating block is slidably connected with multiple limiting rods, and the limiting rods are fixedly connected to the top block.

[0010] Furthermore, a housing is fixedly connected to the upper surface of the chassis, the shaft and the housing are rotatably connected through bearings, and a frame is fixedly connected to the upper surface of the chassis.

[0011] Furthermore, a stirring rod is rotatably connected to the side wall of the housing via a bearing. The stirring rod is slidably connected to the fertilizer tank. A fifth bevel gear is fixedly connected to one end of the stirring rod inside the housing. The fifth bevel gear meshes with the second bevel gear. Multiple blades are fixedly connected to the side wall of the section of the stirring rod inside the fertilizer tank.

[0012] Furthermore, both the first and third pipes are equipped with one-way valves.

[0013] Furthermore, the lower surface of the chassis is engraved with scale lines, and the end of the screw away from the top block is fixedly connected with a bolt.

[0014] Furthermore, both the drive plate and the sidewall of the top block are coated with grease.

[0015] The present invention has the following advantages: 1. The robot moves by walking mechanism. During the movement, it drives the rotating block to rotate, which in turn drives the top block to rotate. The top block and the spring work together to make the sliding column reciprocate, drawing fertilizer from the fertilizer tank into the sliding sleeve and then pumping it out for spraying. Compared with manual fertilization, it greatly reduces labor intensity and labor costs. At the same time, it avoids the harm to the human body caused by long-term exposure to the fertilization environment. 2. By turning the bolt with a wrench, the screw can be rotated, which in turn drives the top block to move. Adjusting the distance between the top block and the rotating block allows for adjustment of the amount of fertilizer sprayed each time, enabling the robot to spray different amounts of fertilizer and greatly improving its applicability. 3. The walking mechanism and the spraying mechanism are driven by the same servo motor, so the walking speed is related to the spraying speed. The faster the walking speed, the faster the spraying speed, thus ensuring that the fertilizer can be sprayed evenly regardless of the walking speed. 4. When the servo motor drives the robot, it drives the second bevel gear to rotate, which in turn drives the fifth bevel gear to rotate. This causes the stirring rod to rotate, which in turn drives the blades to rotate, continuously stirring the fertilizer. This prevents the fertilizer from stratifying and settling, ensuring that the sprayed fertilizer is more even and thus guaranteeing the fertilization effect. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example Reference Figures 1 to 6 A simplified intelligent fertilization robot for planting dryland corn includes a chassis 1. A servo motor 3 is fixedly connected to the upper surface of the chassis 1 via a bracket. The output shaft of the servo motor 3 is fixedly connected to a machine shaft 4. A first bevel gear 5 is fixedly connected to the machine shaft 4. A guard plate 19 is fixedly connected to the lower surface of the chassis 1. A fertilizer box 14 is fixedly connected to the upper surface of the chassis 1. The top wall of the fertilizer box 14 has an opening and a box cover is threadedly connected. A spraying mechanism is provided at the chassis 1. The spraying mechanism consists of a drive assembly and a spraying assembly. The drive assembly includes a rotating shaft 6, which is rotatably connected to the chassis 1 through a bearing. A rotating block 7 is fixedly connected to the rotating shaft 6. The spraying assembly includes a sliding sleeve 11, which is fixedly connected to the lower surface of the chassis 1. A sliding column 12 is slidably connected to the sliding sleeve 11. A drive plate 13 is fixedly connected to the side wall of the sliding column 12 located on the outer side of the sliding sleeve 11. A walking mechanism is provided at the chassis 1. The walking mechanism includes two axles 20, and the axles 20 are rotatably connected to the guard plate 19 through bearings.

[0020] The drive assembly also includes a second bevel gear 2, which is fixedly connected to the end of the rotating shaft 6 away from the rotating block 7. The second bevel gear 2 meshes with the first bevel gear 5. The rotating block 7 is threadedly connected to a screw 8. The end of the screw 8 located outside the rotating block 7 is rotatably connected to a top block 9 via a bearing. The top block 9 abuts against the drive plate 13. According to the amount of fertilizer to be applied each time, the screw 8 is rotated by turning the bolt 10 with a wrench, which in turn causes the screw 8 to rotate. The rotation of the screw 8 will drive the top block 9 to move. The distance between the top block 9 and the rotating block 7 is adjusted. The position of the top block 9 is precisely adjusted according to the scale line 30 on the lower surface of the chassis 1. The adjustment of the position of the top block 9 can adjust the amount of fertilizer sprayed each time, so that the robot can be used for fertilization operations with different amounts of fertilizer, which greatly improves the applicability of the machine.

[0021] The fertilizer box 14, the chassis 1, and the sliding sleeve 11 are all connected by a first pipe 15, which connects the fertilizer box 14 and the sliding sleeve 11. Two fixing blocks 16 are fixedly connected to the upper surface of the chassis 1. The fixing blocks 16 are hollow. The fixing blocks 16, the guard plate 19, and the sliding sleeve 11 are all connected by a third pipe 27, which connects the fixing blocks 16 and the sliding sleeve 11. The side walls of the two fixing blocks 16 on opposite sides are both connected by a second pipe 17. A nozzle 18 is fixedly connected to one end of the second pipe 17 outside the fixing blocks 16. Multiple springs 32 are fixedly connected between the drive plate 13 and the sliding column 12.

[0022] The walking mechanism also includes a third bevel gear 21, which is fixedly connected to the lower surface of the rotating block 7. A fourth bevel gear 22 is fixedly connected to one of the axles 20, and the fourth bevel gear 22 meshes with the third bevel gear 21. Both ends of the axle 20 are fixedly connected to walking wheels 23.

[0023] It is worth mentioning that the walking mechanism and the spraying mechanism are driven by the same servo motor 3, which makes the walking speed related to the spraying speed. The faster the walking speed, the faster the spraying speed, thus ensuring that the fertilizer can be sprayed evenly regardless of the walking speed.

[0024] The rotating block 7 is slidably connected with multiple limiting rods 31. The limiting rods 31 are fixedly connected to the top block 9. By setting the limiting rods 31, the top block 9 can only move along the extension direction of the limiting rods 31, thus preventing rotation.

[0025] A housing 28 is fixedly connected to the upper surface of the chassis 1. The housing 28 provides certain protection for the meshing of the first bevel gear 5, the second bevel gear 2, and the fifth bevel gear 25. The shaft 4 and the housing 28 are rotatably connected through a bearing. A frame 29 is fixedly connected to the upper surface of the chassis 1.

[0026] A stirring rod 24 is rotatably connected through a bearing to the side wall of the housing 28. The stirring rod 24 is slidably connected through the fertilizer box 14. A fifth bevel gear 25 is fixedly connected to one end of the stirring rod 24 inside the housing 28. The fifth bevel gear 25 meshes with the second bevel gear 2. Multiple blades 26 are fixedly connected to the side wall of the section of the stirring rod 24 inside the fertilizer box 14.

[0027] Both the first pipe 15 and the third pipe 27 are equipped with one-way valves. The one-way valve in the first pipe 15 only allows fertilizer to enter the sliding sleeve 11 from the fertilizer box 14, and the one-way valve in the third pipe 27 only allows fertilizer to enter the fixed block 16 from the sliding sleeve 11.

[0028] The lower surface of the chassis 1 is engraved with scale lines 30 (e.g. Figure 2 As shown), the scale line 30 can precisely adjust the position of the top block 9, thereby precisely adjusting the amount of fertilizer sprayed. The end of the screw 8 away from the top block 9 is fixedly connected to a bolt 10, which is an internal hex bolt. The setting of the bolt 10 makes it easier to turn the screw 8 with a wrench.

[0029] Both the drive plate 13 and the top block 9 are coated with grease. The application of grease reduces the friction between the drive plate 13 and the top block 9, thereby preventing excessive friction between them from causing increased wear.

[0030] In this invention, the robot is first inverted. According to the amount of fertilizer required each time, the bolt 10 is turned by a wrench, which causes the screw 8 to rotate. The rotation of the screw 8 will drive the top block 9 to move. The distance between the top block 9 and the rotating block 7 is adjusted. The position of the top block 9 is precisely adjusted according to the scale line 30 on the lower surface of the chassis 1. After the adjustment is completed, the lid of the fertilizer box 14 is opened, and the prepared fertilizer is poured into the fertilizer box 14. The lid is closed, the robot is placed on the field ridge, and the servo motor 3 is turned on.

[0031] The servo motor 3 rotates, driving the first bevel gear 5 to rotate. The first bevel gear 5 drives the second bevel gear 2, which meshes with it, to rotate. The rotation of the second bevel gear 2 drives the rotating block 7 to rotate via the rotating shaft 6. The rotation of the rotating block 7 drives the top block 9 to rotate as well. During the rotation of the top block 9, it works with the spring 32 to cause the drive plate 13 to reciprocate. The drive plate 13 then drives the sliding column 12 to reciprocate. When the sliding column 12 moves closer to the rotating block 7, it draws fertilizer from the fertilizer box 14 into the sliding sleeve 11 through the first tube 15. When the sliding column 12 moves away from the rotating block 7, it draws fertilizer from the fertilizer box 14 into the sliding sleeve 11. The fertilizer in section 1 is pumped into the fixed block 16 through the third pipe 27, and then sprayed out through the second pipe 17 and the nozzle 18 to the plants for fertilization. The rotation of the rotating block 7 will also drive the third bevel gear 21 to rotate. The rotation of the third bevel gear 21 will drive the fourth bevel gear 22 that meshes with it to rotate. The fourth bevel gear 22 will drive the walking wheel 23 to rotate through the wheel axle 20. The rotation of the walking wheel 23 will drive the robot to move forward, so that the robot can complete the spraying and fertilization during the forward movement. After completing the fertilization of one row of field ridges, the robot will be placed at another field ridge and the fertilization will be carried out in the same way.

[0032] During the fertilization process, while the servo motor 3 drives the second bevel gear 2 to rotate, the second bevel gear 2 also drives the fifth bevel gear 25 meshing with it to rotate. The rotation of the fifth bevel gear 25 will drive the stirring rod 24 to rotate, thereby causing the blade 26 to rotate around the stirring rod 24. Through the rotation of the blade 26, the fertilizer in the fertilizer box 14 is continuously stirred to ensure that the fertilizer is mixed evenly.

[0033] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
