Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, and more specifically to a precision fertilization device for crops. Background Technology

[0002] In agricultural production, fertilization plays a crucial role in improving crop yield and quality. Traditional fertilization methods mostly rely on manual experience, which has many drawbacks. Because it is difficult to accurately control the amount and location of fertilizer, it often leads to fertilizer waste, soil pollution, and uneven crop growth. As agriculture moves towards modernization, precision fertilization technology is gaining increasing attention and importance.

[0003] However, some existing fertilization devices operate as follows: first, a tube containing fertilizer granules is carried on the back using a shoulder strap; then, a pole is manually inserted into the soil; and finally, a handbrake mechanism on the pole is operated to rotate a baffle, causing the fertilizer to fall. However, in this feeding mechanism, due to the difficulty in precisely repeating the manual operation, the force, amplitude, and speed of pulling the handbrake each time vary, making it impossible to guarantee that the amount of fertilizer dispensed each time is the same. This makes it difficult to accurately control the amount of fertilizer applied, which can easily lead to localized over-fertilization, causing seedling burn or fertilizer damage, affecting crop growth and even causing plant death; or under-fertilization, failing to meet the crop's growth needs, resulting in poor crop development and reduced yield. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a precision fertilization device for crops to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a precision fertilization device for crops, comprising a feed box, a feeding pipe fixedly connected to the surface of the feed box, and an insert rod fixedly connected to the output end of the feed box. Handrails are fixedly connected to both sides of the insert rod. A feeding groove is formed at the center of the insert rod's interior. Two sliding grooves are formed inside the insert rod, and springs are movably installed inside the sliding grooves. A sealing plate is slidably connected inside the sliding grooves, and a slider is fixedly connected to the bottom of the sealing plate. A toothed plate is fixedly connected inside the insert rod. A first gear, a second gear, and a third gear are rotatably connected inside the slider. A fourth gear is fixedly connected to the center of the surfaces of the second and third gears. Toothed belts are meshed on the surfaces of the two fourth gears. An insert block is rotatably connected to the outer surface of the slider. A connecting pipe is fixedly connected inside the insert rod. A limiting groove is formed inside the insert rod, and a sealing block is slidably connected inside the limiting groove. A baffle plate is fixedly connected to the surface of the sealing block, and a material passage hole is formed on the surface of the baffle plate. A positioning block is slidably connected inside the insert rod, and a bolt is installed through the positioning block.

[0006] Furthermore, the end of the feeding pipe away from the material box is connected to the inside of the feeding trough, and the diameter of the material passage hole matches the diameter of the feeding trough.

[0007] Furthermore, the inner top of one of the slide grooves is connected to the inside of the limiting groove through a connecting pipe. Under normal conditions, the elasticity of the spring keeps the inside of the limiting groove in a negative pressure state. The inner top of the other slide groove is connected to the outside of the insertion rod.

[0008] Furthermore, the outer surface of the baffle plate is inserted into the inside of the feeding groove, the outer surface of the bolt is rotatably connected to the inside of the insert rod through a bearing, and the bottom of the positioning block extends into the inside of the limiting groove.

[0009] Furthermore, a semi-circular ring is fixedly connected to the top of the outer surface of the insert, and the insert is semi-conical.

[0010] Furthermore, the surface of the first gear is engaged with the surface of the gear plate, the surface of the first gear is engaged with the surface of the second gear, and the surface of the third gear, away from the fourth gear, is fixedly connected to the inside of the insert block.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] This invention involves inserting a block into the soil using a handrail. Due to pressure, the insert slides downwards, and the engagement of the first gear and toothed plate opens the block, clearing away clods of soil. Simultaneously, the limiting groove is under high pressure, causing the baffle plate to slide. When the material passage and the discharge trough intersect, fertilizer passes through the material passage and the material passage, falling into the soil hole from the bottom of the trough. By rotating the bolt, the sliding of the baffle plate can be positioned, controlling the size of the intersection between the material passage and the discharge trough. This allows for precise control of the amount of fertilizer falling, achieving accurate fertilization. While clearing away clods, the fertilizer falls directly into the soil hole via the structure, eliminating the need for additional complex fertilizer placement. The entire fertilization process is smoother and faster, further improving fertilization efficiency. Attached Figure Description

[0018] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0019] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0020] Specifically, a precision fertilization device for crops includes a feed hopper 1, a feeding pipe 2 fixedly connected to the surface of the feed hopper 1, and an insertion rod 3 fixedly connected to the output end of the feed hopper 1. Handrails 4 are fixedly connected to both sides of the insertion rod 3. A feeding groove 5 is formed at the center of the insertion rod 3. Two sliding grooves 6 are formed inside the insertion rod 3. Springs 7 are movably installed inside the sliding grooves 6. A sealing plate 8 is slidably connected inside the sliding grooves 6. A slider 9 is fixedly connected to the bottom of the sealing plate 8. A toothed plate 10 is fixedly connected inside the insertion rod 3. A first gear 11, a second gear 12, and a third gear are rotatably connected inside the slider 9. A fourth gear 14 is fixedly connected to the center of the surfaces of the wheel 13, the second gear 12, and the third gear 13. A toothed belt 15 is installed on the meshing surfaces of the two fourth gears 14. An insert block 16 is rotatably connected to the outer surface of the slider 9. A connecting pipe 17 is fixedly connected inside the insert rod 3. A limit groove 18 is opened inside the insert rod 3. A sealing block 19 is slidably connected inside the limit groove 18. A baffle plate 20 is fixedly connected to the surface of the sealing block 19. A material passage hole 21 is opened on the surface of the baffle plate 20. A positioning block 23 is slidably connected inside the insert rod 3. A bolt 22 is installed through the inside of the positioning block 23.

[0021] In this implementation scheme, the handle 4 is used to insert the insert 16 into the soil. The pressure causes the insert rod 3 to slide down. The gear and toothed plate 10 work together to open the insert 16 and push away the soil clods. At the same time, the strong pressure causes the baffle plate 20 to slide, allowing the fertilizer to fall into the soil hole through the discharge chute 5 and the discharge hole 21. The amount of fertilizer falling can be controlled by rotating the bolt 22 to achieve precise fertilization. Moreover, this method does not require complicated fertilizer placement operations and can improve fertilization efficiency.

[0022] Specifically, the end of the feed pipe 2 away from the material box 1 is connected to the inside of the feed trough 5, and the diameter of the feed hole 21 matches the diameter of the feed trough 5.

[0023] In this embodiment, the amount of fertilizer falling can be controlled by the size of the intersection between the material passage 21 and the material discharge trough 5.

[0024] Specifically, the top of the inside of one of the slide grooves 6 is connected to the inside of the limiting groove 18 through the connecting pipe 17. Under normal conditions, the elasticity of the spring 7 keeps the inside of the limiting groove 18 in a negative pressure state. The top of the inside of the other slide groove 6 is connected to the outside of the insertion rod 3.

[0025] In this embodiment, by setting spring 7, when fertilization is not required, the elasticity of spring 7 can cause baffle plate 20 to slide to the left to seal the inside of the feed trough 5, preventing fertilizer from falling.

[0026] Specifically, the outer surface of the baffle plate 20 is inserted into the inside of the feed trough 5, the outer surface of the bolt 22 is rotatably connected to the inside of the insert rod 3 through the bearing, and the bottom of the positioning block 23 extends into the inside of the limiting groove 18.

[0027] In this embodiment, rotating the bolt 22 can drive the positioning block 23 to slide, thereby positioning the sliding distance of the baffle plate 20.

[0028] Specifically, a semi-circular ring is fixedly connected to the top of the outer surface of the insert 16, and the insert 16 is semi-conical.

[0029] In this embodiment, since a semi-circular ring is fixedly connected to the top of the outer surface of the insert 16, the friction between the semi-circular ring and the ground can be increased, so that the insert rod 3 can slide down the surface of the sealing plate 8 after being subjected to downward pressure.

[0030] Specifically, the surface of the first gear 11 is meshed with the surface of the toothed plate 10, the surface of the first gear 11 is meshed with the surface of the second gear 12, and the surface of the third gear 13, which is away from the fourth gear 14, is fixedly connected to the inside of the insert block 16.

[0031] In this embodiment, the first gear 11 of the toothed plate 10 can be engaged to drive the insert block 16 to rotate.

[0032] The working principle and usage process of this utility model are as follows: In use, first adjust the position of the positioning block 23 according to the required amount of fertilizer. Using the forward and reverse bolts 22, the positioning block 23 can slide left and right inside the insert rod 3. When the positioning block 23 slides to the left, the distance the baffle plate 20 can slide to the right is shortened, thus reducing the intersection of the material passage hole 21 and the discharge trough 5, and decreasing the amount of fertilizer applied. When the positioning block 23 slides to the right, the distance the baffle plate 20 can slide to the right is lengthened, increasing the intersection of the material passage hole 21 and the discharge trough 5, thus increasing the amount of fertilizer applied. After adjusting the amount of fertilizer, the worker carries the material box 1 on their back and inserts the insert block 16 into the desired fertilizer position using the handle 4. Due to the pressure, the insert rod 3 slides downwards. Through the meshing of the first gear 11 and the toothed plate 10, the first gear 11 drives the second... Gear 12 rotates, and then through the fourth gear 14 and the toothed belt 15, it drives the third gear 13 and the insert block 16 to rotate away from the center of the feeding trough 5, and opens the insert block 16, which can clear away the soil clods on the ground. At the same time, when the sealing plate 8 slides upward, the inside of the limiting groove 18 is under strong pressure. The sealing block 19 drives the baffle plate 20 to slide to the right. When the material passage hole 21 intersects with the feeding trough 5, the fertilizer can pass through the material passage hole 21 and fall into the soil hole from the bottom of the feeding trough 5, realizing rapid fertilization and precise fertilization. When the handle 4 pulls the insert rod 3 upward, there is no pressure between the insert block 16 and the ground. Due to the elasticity of the spring 7, the sealing plate 8 drives the slider 9 to slide downward, the insert block 16 closes, and the baffle plate 20 seals the inside of the feeding trough 5, so the fertilizer will not fall.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
