Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to an intelligent precision side-deep fertilization machine and method for rice. Background Technology

[0002] Currently, farmers in most major rice-producing areas of my country still primarily use basal fertilizer plus topdressing. Basal fertilizer is typically applied manually, shallowly, or by simple mechanical spreading on the surface, then mixed into the 0-12cm tillage layer during land preparation. This method results in poor fertilizer uniformity, easily leading to significant differences in rice plant growth and ultimately causing unstable yield and quality. The utility model application CN202122592964.8 provides a rice transplanter with a side-deep fertilization function, including a frame, connecting frame, feeding bin support frame, feeding bin, balancing mechanism, transplanting mechanism, side-deep fertilization mechanism, seedling support plate, fertilizer delivery pipe, and sliding plate. This equipment is inexpensive to manufacture and compact, making it suitable for small to medium-sized users. Users can perform side-deep fertilization simultaneously with mechanized rice transplanting. It is equipped with a simple balancing mechanism to ensure operational stability and addresses the problem of the high hardness of the mud at the bottom of the paddy field, where the equipment's own weight makes it difficult to press the plow blades deep into the mud. However, during use, because the fertilizer pipe is located inside the plow blade, although a pneumatic feeding mechanism prevents backflow of mud and water, the amount of fertilizer cannot be well controlled if the air injection is too large, or if the air injection is too small, the pneumatic feeding mechanism cannot effectively prevent backflow under soil pressure. Therefore, the fertilizer pipe is easily blocked, preventing normal fertilization. Furthermore, when fertilizing rice, fertilization can only be done on one side, easily leading to uneven fertilization, inaccurate fertilization, and poor fertilization results. Summary of the Invention

[0003] The purpose of this invention is to provide an intelligent precision side-deep fertilization machine and method for rice. By starting the first rotary motor to adjust the position of the limiting plate, the depth of the furrowing blade inserted into the mud and water is adjusted, thereby achieving the effect of adjusting the fertilization depth and improving the accuracy of the fertilization depth. By activating the electric heating wire in the heating plate, the fertilizer is dried while being stirred, preventing the fertilizer from becoming damp and clumping. During feeding, the fertilizer falls in whole pieces, making it difficult to control the amount of fertilizer applied. This method makes the fertilizer fall more evenly and ensures the accuracy of the amount of fertilizer applied. By starting the feeding motor, the fertilizer in the feeding pipe is delivered to the discharge ports at both ends of the feeding pipe and then delivered to both sides of the rice. This allows for simultaneous fertilization of both sides of the rice, improving the efficiency of fertilization and ensuring the accuracy of fertilization. The discharge ports are located inside the furrowing mechanism, preventing the discharge ports from being blocked by mud and water, thus solving the problems mentioned in the background art.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. This invention discloses an intelligent precision side-deep fertilizer for rice. By starting a first rotary motor, the rotating gear rotates, which in turn drives the rack to move up and down, adjusting the position of the limiting plate and thus adjusting the depth of the furrowing blade inserted into the mud and water. This achieves the effect of adjusting the fertilization depth and improves the accuracy of the fertilization depth. The mudguard seals the groove and can stretch or contract with the movement of the limiting plate, preventing mud and water from entering the groove during furrowing and affecting the accuracy of the limiting. The drill bit makes furrowing faster and avoids soil clumping and difficulty in furrowing. By activating the electric heating wire in the heating plate, the fertilizer is dried while being stirred, preventing the fertilizer from getting damp and clumping. The fertilizer falls in whole pieces during feeding, making it easier to control the amount of fertilizer applied. This results in more even fertilizer application and ensures the accuracy of the fertilizer amount.

[0022] 2. The present invention provides an intelligent precision side-deep fertilizer for rice. By starting the feeding motor, the screw feeding rod rotates, and the fertilizer in the feeding pipe is transported to the discharge ports at both ends of the feeding pipe. The fertilizer is then transported from the discharge ports to both sides of the rice. This allows for simultaneous fertilization of both sides of the rice, improving fertilization efficiency and ensuring fertilization accuracy. The discharge ports are located inside the ditching mechanism, preventing mud and water from clogging the discharge ports. Attached Figure Description

Detailed Implementation

[0033] 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 embodiments of the present invention, and not all embodiments. 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.

[0034] To address the issues in existing fertilization devices where the fertilizer pipe is located inside the plow blades and a pneumatic feeding mechanism is used to prevent backflow of mud and water, the plow blades need to penetrate deep into the soil during operation. If the air injection is too high, the amount of fertilizer delivered cannot be well controlled; if the air injection is too low, the pneumatic feeding mechanism cannot effectively prevent backflow under soil pressure, thus easily clogging the fertilizer pipe and hindering normal fertilization. Please refer to [link to relevant technical documentation]. Figures 1-4 This embodiment provides the following technical solution:

[0035] An intelligent precision side-deep fertilizer for rice includes a frame 1 and a support plate 3. The support plate 3 is fixed inside the frame 1. A fertilization mechanism 2 is installed on the support plate 3. The fertilization mechanism 2 extends to the top of the frame 1. A mixing mechanism 6 is installed inside the fertilization mechanism 2. A ditching mechanism 4 is provided below the support plate 3. The ditching mechanism 4 is rotatably installed on the inner side wall of the frame 1. Movable mechanisms 5 are provided on both sides of the bottom of the frame 1.

[0036] The fertilization mechanism 2 includes a fertilizer box 21, a box cover 22, a feed pipe 23, a feeding mechanism 24, and a discharge mechanism 25. The top of the fertilizer box 21 is equipped with a box cover 22, and the box cover 22 is equipped with a feed pipe 23. The bottom of the fertilizer box 21 is equipped with a discharge mechanism 25, which includes a feeding motor 251, a feeding pipe 252, a partition 253, a screw feed rod 254, a discharge port 255, and a discharge pipe 256. The feeding motor 251 is installed on the outside of the feeding pipe 252, and its output end is connected to the screw feed rod 254. The screw feed rod 254 is rotatably mounted on the inner wall of the feeding pipe 252. Both ends of the feeding pipe 252 have discharge ports 255 at their bottoms, and the top of the feeding pipe 252 has a discharge pipe 256. The discharge pipe 256 is installed on... On the lower surface of the feeding mechanism 24, a partition 253 is provided at the point where the feeding pipe 252 and the feeding pipe 256 communicate. The feeding mechanism 24 is provided at the connection between the discharge mechanism 25 and the fertilizer box 21. The feeding mechanism 24 includes a baffle 241, a mounting plate 242, a hydraulic rod 243, a connecting rod 244, a mounting component 245, and a mounting shaft 246. Two baffles 241 are provided. One end of the baffle 241 is provided with a mounting component 245. The mounting component 245 is rotatably mounted on the mounting shaft 246. One end of the mounting shaft 246 is mounted on the bottom of the fertilizer box 21, and the other end is mounted on the discharge mechanism 25. A connecting rod 244 is fixed on the baffle 241. The connecting rods 244 are arranged crosswise. A mounting plate 242 is provided on the connecting rod 244. A hydraulic rod 243 is mounted on the mounting plate 242.

[0037] Specifically, by activating the hydraulic rod 243, the distance between the two connecting rods 244 is adjusted, causing the connecting rods 244 to pull the baffle 241 outward, thereby opening the discharge pipe 256. This facilitates the delivery of fertilizer from the fertilizer box 21 to the feeding pipe 252. The partition 253 is used to deliver fertilizer to both ends of the feeding pipe 252. When the fertilizer falls into the feeding pipe 252, the feeding motor 251 is activated, causing the screw feeder 254 to rotate. This delivers the fertilizer from the feeding pipe 252 to the discharge ports 255 at both ends of the feeding pipe 252, and then from the discharge ports 255 to both sides of the rice paddy. This allows for simultaneous fertilization of both sides of the rice paddy, improving fertilization efficiency and ensuring fertilization accuracy. Simultaneously, the soil covering plate 45 covers the fertilizer with soil, improving the fertilization effect. The discharge port 255 is located inside the ditching mechanism 4, preventing mud and water from clogging the discharge port 255.

[0038] To address the technical problem that existing fertilization devices can only apply fertilizer to one side of the rice plant, resulting in uneven fertilization, inaccurate fertilization, and poor fertilization effects, please refer to [link to relevant documentation]. Figure 5-Figure 9 This embodiment provides the following technical solution:

[0039] The trenching mechanism 4 includes a trenching plate 41, trenching cutters 42, a rotating shaft 43, a connecting column 44, a soil covering plate 45, a limiting mechanism 46, and a second rotating motor 47. Several trenching cutters 42 are provided, with two cutters 42 forming a group. A groove is formed on the outer side of one trenching cutter 42, and the limiting mechanism 46 is installed in the groove. The limiting mechanism 46 includes a limiting plate 461, a sliding rod 462, a mudguard 463, a first rotating motor 464, a rotating gear 465, a rack 466, and a slider 467. The slider 467 and rack 466 are fixedly installed on one side of the limiting plate 461. The rotating gear 465 meshes with the rack 466. The rotating gear 465 is rotatably mounted on the inner wall of the groove via a drive shaft, which is installed at the output end of the first rotating motor 464. The slider 467 is slidably mounted on the sliding rod 462, which is located within the groove. A mudguard is provided at the opening of the groove. 463, the mudguard 463 is installed on the lower surface of the limiting plate 461 at the end away from the groove. The mudguard 463 is stretchable. The tail of the trenching cutter 42 is fixed with a connecting column 44. The bottom of the connecting column 44 is provided with a soil covering plate 45. The trenching cutter 42 is installed on the rotating shaft 43. The rotating shaft 43 is rotatably installed on the inner wall of the frame 1. The rotating shaft 43 is installed at the output end of the second rotating motor 47. The discharge port 255 is set on the inner side of the trenching cutter 42. The front end of the trenching cutter 42 is provided with a trenching plate 41. The trenching plate 41 includes a connecting shaft 411, a front plate 412, a connecting plate 413, a support rod 414 and a drill bit 415. Two front plates 412 are rotatably installed on the connecting shaft 411. The inner side of the front plate 412 is provided with a support rod 414. The support rod 414 is movably installed on the connecting plate 413. The connecting plate 413 is fixed on the trenching cutter 42. The outer side of the connecting shaft 411 is provided with a drill bit 415.

[0040] Specifically, by activating the second rotary motor 47, the rotating shaft 43 rotates, facilitating the insertion of the furrowing blade 42 into the mud and water on both sides of the rice paddy. When not in use, the furrowing blade 42 can be rotated upwards without affecting the normal movement of the device when not in operation. By activating the first rotary motor 464, the drive shaft rotates, driving the rotating gear 465 to rotate, which in turn drives the rack 466 to move up and down, adjusting the position of the limit plate 461, and thus adjusting the depth of the furrowing blade 42 inserted into the mud and water. This achieves the effect of adjusting the fertilization depth and improving fertilization efficiency. To ensure the accuracy of fertilization depth, the two ends of the limiting plate 461 are movably mounted on the sliding rod 462 via sliders 467, guaranteeing the stability of the limiting plate 461. At the same time, the mudguard 463 seals the groove and can stretch or contract with the movement of the limiting plate 461, preventing mud and water from entering the groove during trenching and affecting the accuracy of the limiting. While the moving mechanism 5 moves, the trenching plate 41 on the trenching cutter 42 trenches, and the drill bit 415 makes trenching faster and avoids soil clumping and trenching difficulties.

[0041] The moving mechanism 5 includes a drive gear 51, a moving motor 52, a pulley 53, a driven shaft 54, and a driven gear 55. One end of the drive gear 51 is mounted on the moving motor 52, and the other end is rotatably mounted on the outer wall of the frame 1. The pulley 53 meshes with the outer side of the drive gear 51. The end of the pulley 53 away from the drive gear 51 is mounted on the driven gear 55. The driven gear 55 is rotatably mounted on the outer wall of the frame 1 through the driven shaft 54.

[0042] Specifically, by starting the mobile motor 52, the drive gear 51 is rotated, which in turn drives the pulley 53 to move. The pulley 53 drives the driven gear 55 to rotate, which in turn drives the frame 1 to move, making it easier to move the device to the paddy field. The pulley 53 has a large contact area with the surface of the paddy field, which prevents the frame 1 from sinking due to the weight of the device during use.

[0043] The stirring mechanism 6 includes a stirring motor 61, a stirring shaft 62, stirring blades 63, and a heating plate 64. The output end of the stirring motor 61 is connected to the stirring shaft 62. Several stirring blades 63 are fixed on the stirring shaft 62. The end of the stirring blade 63 away from the stirring shaft 62 is installed on the heating plate 64. The heating plate 64 is provided with an electric heating wire.

[0044] Specifically, by starting the stirring motor 61, the stirring shaft 62 rotates, which in turn drives the stirring blades 63 to stir the fertilizer. At the same time, the electric heating wire in the heating plate 64 is activated to dry the fertilizer, preventing it from getting damp and clumping. The fertilizer falls in one piece during feeding, which makes it easier to control the amount of fertilizer applied. This method makes the fertilizer fall more evenly and ensures the accuracy of the fertilizer application.

[0045] To better implement the operation method of an intelligent precision side-deep fertilization machine for rice, the following steps are included:

[0046] Step 1: Fill the fertilizer box 21 with fertilizer, start the stirring motor 61 to make the stirring shaft 62 rotate, which in turn drives the stirring blades 63 to stir the fertilizer. At the same time, start the electric heating wire in the heating plate 64 to dry the fertilizer.

[0047] Step 2: Start the mobile motor 52 to make the drive gear 51 rotate, which in turn drives the pulley 53 to move. The pulley 53 drives the driven gear 55 to rotate, which in turn drives the frame 1 to move, moving the device to the rice field.

[0048] Step 3: Start the second rotary motor 47 to rotate the rotating shaft 43, insert the ditching blade 42 into the mud and water on both sides of the rice paddy, start the first rotary motor 464 to rotate the drive shaft, drive the rotating gear 465 to rotate, and then drive the rack 466 to move up and down, adjust the position of the limit plate 461. While the moving mechanism 5 is moving, the ditching plate 41 on the ditching blade 42 opens the ditch. The drill bit 415 makes ditching faster and avoids soil clumping and difficulty in ditching.

[0049] Step 4: Start the hydraulic rod 243 and adjust the distance between the two connecting rods 244 so that the connecting rods 244 pull the baffle 241 outward, open the feed pipe 256, and transport the fertilizer in the fertilizer box 21 to the feed pipe 252. The set baffle 253 transports the fertilizer to both ends of the feed pipe 252. Start the feed motor 251 to make the screw feed rod 254 rotate, and transport the fertilizer in the feed pipe 252 to the discharge ports 255 at both ends of the feed pipe 252, and from the discharge ports 255 to both sides of the rice.

[0050] In summary, the intelligent precision side-deep fertilization machine for rice of the present invention, by starting the feeding motor 251, causes the screw feeding rod 254 to rotate, conveying the fertilizer in the feeding pipe 252 to the discharge ports 255 at both ends of the feeding pipe 252, and then conveying it from the discharge ports 255 to both sides of the rice, can simultaneously fertilize both sides of the rice, improving fertilization efficiency and ensuring fertilization accuracy. The discharge ports 255 are located inside the ditching mechanism 4, preventing the discharge ports 255 from being blocked by mud and water. By starting the first rotary motor 464, the rotary gear 465 rotates, thereby driving the rack 466 to move up and down, adjusting the position of the limit plate 461, and thus adjusting... The depth to which the trenching cutter 42 is inserted into the mud and water achieves the effect of adjusting the fertilization depth, improving the accuracy of the fertilization depth. The mudguard 463 seals the groove and can stretch or contract with the movement of the limit plate 461, preventing mud and water from entering the groove during trenching and affecting the accuracy of the limit. The drill bit 415 makes trenching faster and avoids soil clumping and trenching difficulties. By activating the electric heating wire in the heating plate 64, the fertilizer is dried while being stirred, preventing the fertilizer from getting damp and clumping. When discharging, the fertilizer falls in one piece, making it easier to control the amount of fertilizer. This makes the fertilizer fall more evenly and ensures the accuracy of the fertilizer amount.

[0051] 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.
