[0002] With the continuous growth of the global population and the upgrading of dietary structure, the total demand and quality requirements for food and various agricultural products are constantly increasing. Agricultural production is facing the dual pressure of ensuring supply and improving efficiency. As the foundation of agricultural production, the level of precision and standardization of planting operations directly affects the yield and quality of crops.

[0003] Topdressing is one of the important measures to ensure the normal growth and nutrient supply of plants. Topdressing usually includes hole application or spot application. The operation method is to dig or punch a hole in the ground, pour a certain amount of fertilizer into the hole, and then water it. This can reduce fertilizer volatilization, avoid surface runoff loss, and improve utilization rate. However, due to the large number of holes, the traditional manual operation method requires a lot of manpower and time and is inefficient. Summary of the Invention

The sleeves are inserted into the rolling body and communicate with each other. The sleeves are used to supply fertilizer into the rolling body. The rolling body rotates on the sleeves. The outer circumferential wall of the rolling element is provided with a plurality of tubes, and the opening of the tubes is provided with a sealing plate that can be opened or closed.

[0005] Furthermore, the inner lower side of the rolling element has a filler, the upper surface of the filler is inclined, and the filler is fixedly connected to the sleeve through a connecting plate.

[0006] Furthermore, the insertion tube consists of a fixed tube connected to the outer wall of the rolling element and a movable chamber slidably mounted on the fixed tube, and the sealing plate is used to control the opening and closing of the movable chamber.

[0007] Furthermore, the activity chamber consists of a sliding area, a storage area, and a breaking soil area. The sliding area is used to slide and connect with the fixed pipe. The storage area and the breaking soil area are used to store fertilizer, and the breaking soil area is conical in shape.

[0008] Furthermore, a diagonal pull arm is rotatably mounted on the outer wall of the active chamber, and an adjusting ring is rotatably mounted on the outer wall of the rolling element. Each diagonal pull arm is rotatably connected to the adjusting ring, and the adjusting ring is fastened to the rolling element by bolts.

[0009] Furthermore, each of the fixed tubes is rotatably provided with a rotating column on its side wall, the sealing plate is connected to the rotating column, the rotating column is connected to the rolling element through a number of elastic bodies, the rotating column is provided with a lever arm, and the outer wall of the rolling element is provided with a pushing structure for moving the lever arm.

[0010] Furthermore, the pushing structure consists of a fixed plate installed on the outer wall of the sleeve and several rollers installed on the outer wall of the fixed plate. Both ends of the fixed plate are inclined, and the middle part of the fixed plate is arc-shaped.

[0011] Furthermore, each of the sleeves is connected to a conveying pipe, and each of the sleeves is provided with a slope that is inclined toward the rolling element.

[0012] The beneficial effects of this invention are as follows: By using a rolling element to continuously drive several tubes and sealing plates into the ground, cavities are easily formed on the ground, allowing fertilizer to be automatically introduced into each cavity. This achieves automated fertilizer planting, greatly simplifying the operation, saving manpower, and improving work efficiency. Attached Figure Description

[0019] like Figures 1 to 9 As shown, an automatic fertilizer and fertilizer planter for agricultural planting according to the present invention includes several fertilizer and fertilizer units 1 arranged side by side. Each fertilizer and fertilizer unit 1 includes a rolling body 2 and two sleeves 3 installed on both ends of the rolling body 2. The rolling body 2 is hollow inside, and the sleeves 3 are inserted into the rolling body 2 and connected to each other. The sleeves 3 are used to supply fertilizer into the rolling body 2, and the rolling body 2 rotates on the sleeves 3. A plurality of tubes 4 are connected to the outer circumference of the rolling element 2, and the opening of the tubes 4 is provided with a sealing plate 5 that can be opened or closed. In this invention, several fertilizer planting units 1 arranged side by side can be installed on a mobile carrier, thereby driving the fertilizer planting units 1 to move on the ground and carry out fertilizer planting work. The simultaneous operation of the fertilizer planting units 1 can increase the fertilizer planting area during a single trip of the carrier, thereby improving work efficiency. The two sleeves 3 on the fertilizer planting unit 1 are located on the two end faces of the rolling body 2, and the two sleeves 3 can support the rolling body 2, so that the rolling body 2 can roll on the ground, thereby driving the several insertion tubes 4 and the sealing plate 5 on it to move synchronously. At the same time, the sleeves 3 can be used to deliver fertilizer into the rolling body 2. The sleeves 3 can be installed on the carrier through the frame 22 fixedly connected to them. The several insertion tubes 4 installed on the outer circumference of the rolling body 2 are mainly used to penetrate into the ground and guide the fertilizer in the rolling body 2 into the hole through the insertion tubes 4, thereby realizing fertilizer planting work. The sealing plate 5 is used to seal the insertion tubes 4 before they penetrate into the ground to prevent fertilizer from flowing out through the insertion tubes 4. In use, fertilizer is continuously introduced into the rolling body 2 through one or two sleeves 3. The carrier drives the rolling body 2 to roll on the ground through the sleeves 3. While the rolling body 2 is rolling, it drives several insertion tubes 4 and sealing plates 5 to move synchronously. When the insertion tubes 4 and sealing plates 5 move close to the ground, they penetrate into the ground. When the insertion tubes 4 and sealing plates 5 penetrate to a specified depth, the sealing plates 5 open, and the fertilizer in the rolling body 2 can be introduced into the hole through the insertion tubes 4. As the rolling body 2 rolls, the insertion tubes 4 and sealing plates 5 gradually move upward. At this time, the sealing plates 5 close the opening of the insertion tubes 4 again, and the fertilizer stops being discharged, thus completing one fertilizer planting operation. With the continuous rolling of the rolling body 2 and the synchronous movement of several insertion tubes 4 and several sealing plates 5, continuous fertilizer planting can be achieved. By using the rolling body 2 to roll on the ground and drive several insertion tubes 4 and several sealing plates 5 to continuously penetrate into the ground, it is convenient to continuously form cavities on the ground, so that fertilizer can be automatically introduced into each cavity, thereby realizing automatic fertilizer planting, greatly simplifying the operation, saving manpower, and improving work efficiency.

[0020] Furthermore, the inner lower side of the rolling element 2 has a filler 20, the upper surface of the filler 20 is inclined, and the filler 20 is fixedly connected to the sleeve 3 through the connecting plate 21. When the fertilizer is being applied, when the insertion tube 4 moves to the underside of the rolling body 2 and the sealing plate 5 is opened, a large amount of fertilizer inside the rolling body 2 will flow out through the insertion tube 4. This makes it impossible to effectively control the amount of fertilizer applied. The filler 20 can be used to seal the insertion tube 4 when it moves to the underside of the rolling body 2. That is, when the insertion tube 4 moves to the side of the rolling body 2, the fertilizer inside the rolling body 2 will enter the insertion tube 4. Then, as the insertion tube 4 continues to move, the filler 20 seals the insertion tube 4, thus isolating the fertilizer. When the sealing plate 5 is opened, only the fertilizer inside the insertion tube 4 flows out, thereby controlling the amount of fertilizer applied. The inclined surface on the upper surface of the filler 20 is mainly used to guide the fertilizer, allowing it to flow smoothly into the insertion tube 4 without accumulating on the filler 20. Since the rolling element 2 needs to rotate continuously, the filler 20 only seals the tube 4 that has moved to a specific position. Therefore, the position of the filler 20 inside the rolling element 2 cannot be moved. That is, the filler 20 and the sleeve 3 are relatively fixed. In this way, the connection between the filler 20 and the sleeve 3 can be achieved through the connecting plate 21.

[0021] Furthermore, the insertion tube 4 consists of a fixed tube 6 connected to the outer wall of the circumference of the rolling element 2 and an active chamber 7 slidably installed on the fixed tube 6. The sealing plate 5 is used to control the opening and closing of the active chamber 7. In actual operation, due to different crops and different timing of topdressing, the amount of fertilizer needs to be adjusted and controlled. By using the sliding method of the movable chamber 7 on the fixed tube 6 in the above structure, the total space size of the fixed tube 6 and the movable chamber 7 can be adjusted, thereby adjusting the amount of fertilizer stored inside the insertion tube 4.

[0022] Furthermore, the activity room 7 consists of a sliding area 8, a storage area 9, and a breaking soil area 10. The sliding area 8 is used to slide and connect with the fixed pipe 6. The storage area 9 and the breaking soil area 10 are used to store fertilizer, and the breaking soil area 10 is conical in shape. Because the activity room 7 needs to be slidably connected to the fixed pipe 6, and the activity room 7 needs to be embedded in the ground, the shape of the activity room 7 needs to be specially designed, such as... Figure 7 The activity chamber 7 is divided into a sliding area 8, a storage area 9 and a breaking ground area 10 from top to bottom. The sliding area 8 is used to slide and connect with the fixed pipe 6, the storage area 9 is used to store fertilizer, and the breaking ground area 10 is used to penetrate the ground. This distinction between different areas makes it easier to use the activity chamber 7. When the activity chamber 7 moves on the fixed pipe 6, the size of the space exposed in the storage area 9 changes, thereby adjusting the amount of fertilizer. For ease of processing and use, activity room 7 can be configured as follows: Figure 7As shown, the bottom of the trough-shaped active chamber 7 is inclined, and the side opening of the active chamber 7 is an opening. The size of the opening is related to its height position on the fixed pipe 6. That is, when the active chamber 7 moves downward, the area of ​​the fixed pipe 6 covering the opening of the active chamber 7 decreases, and the opening increases. Thus, the opening size can be adjusted at the same time as the amount of fertilizer stored. The more fertilizer stored, the larger the corresponding opening, which facilitates the timely discharge of fertilizer and avoids the situation where the opening size remains unchanged or decreases when the amount of fertilizer stored is large, resulting in the fertilizer not being able to be discharged in time.

[0023] Furthermore, a diagonal arm 11 is rotatably mounted on the outer wall of the activity chamber 7, and an adjusting ring 12 is rotatably mounted on the outer wall of the rolling body 2. Each diagonal arm 11 is rotatably connected to the adjusting ring 12, and the adjusting ring 12 is fastened to the rolling body 2 by bolts. Since the position of the active chamber 7 on the fixed tube 6 is adjustable, in order to achieve the purpose of synchronous adjustment of several active chambers 7, the adjusting ring 12 can be rotated so that the adjusting ring 12 pushes several active chambers 7 to slide on the fixed tube 6 through multiple inclined pull arms 11. This synchronous adjustment method can ensure that the fertilizer storage amount in each insertion tube 4 is the same, and simplifies the adjustment method, avoiding the manual consumption of adjusting one by one. The adjusting ring 12 can be fastened to the rolling body 2 by bolts or set screws, thereby locking the position of each active chamber 7 on the fixed tube 6.

[0024] Furthermore, each fixed tube 6 has a rotating column 13 rotatably mounted on its side wall. The sealing plate 5 is connected to the rotating column 13. The rotating column 13 is connected to the rolling body 2 through several elastic bodies 14. The rotating column 13 is equipped with a lever arm 15. The outer wall of the rolling body 2 is equipped with a pushing structure for moving the lever arm 15. In its natural state, the elastic body 14 provides elastic thrust to the rotating column 13, causing the sealing plate 5 to fit against the opening of the movable chamber 7, thereby keeping the insertion tube 4 closed. The insertion tube 4 rotates with the rolling body 2, and the rotating column 13, elastic body 14 and lever arm 15 on it move synchronously. When the insertion tube 4 moves to the specified position, the lever arm 15 moves to the position of the pushing structure. At this time, as the rolling body 2 continues to rotate, the pushing structure uses the lever arm 15 to push the rotating column 13 to rotate, thereby opening the sealing plate 5. When the lever arm 15 separates from the pushing structure, the elastic body 14 pushes the sealing plate 5 to close again.

[0025] Furthermore, the pushing structure consists of a fixed plate 16 installed on the outer wall of the sleeve 3 and several rollers 17 installed on the outer wall of the fixed plate 16. Both ends of the fixed plate 16 are inclined, and the middle part of the fixed plate 16 is arc-shaped. The inclined design at both ends of the fixed plate 16 allows the fixed plate 16 to use several rollers 17 on it to push the lever arm 15 to gradually tilt, avoiding friction damage. The arc center in the middle of the fixed plate 16 coincides with the center of the rolling element 2. In this way, when the lever arm 15 moves relative to the fixed plate 16, the tilt angle of the lever arm 15 remains unchanged, that is, the opening angle of the sealing plate 5 remains unchanged. like Figure 2 As shown, the fixed plate 16 and several rollers 17 are located on the side of the rolling body 2. When the insertion tube 4 moves to the lowest side of the rolling body 2, the corresponding lever 15 can contact the rollers 17 on the fixed plate 16, thereby opening the sealing plate 5. As the lever 15 moves on the fixed plate 16, the sealing plate 5 can remain open and move a specified distance. This makes it easy to drain the fertilizer from the insertion tube 4 and prevents the sealing plate 5 from closing and pushing some soil into the insertion tube 4 during the process. When the insertion tube 4 and the sealing plate 5 move above the ground, the sealing plate 5 closes again. This ensures that even if there is a small amount of soil inside the insertion tube 4, the soil inside the insertion tube 4 will naturally fall off when it moves to the ground, thus preventing soil from remaining inside the insertion tube 4.

[0026] Furthermore, each sleeve 3 is connected to a material conveying pipe 19, and each sleeve 3 is provided with a slope 18 inclined towards the rolling element 2. The feed pipe 19 is used to feed fertilizer into the casing 3. The slope 18 inside the casing 3 is mainly used to guide the fertilizer, thereby preventing the fertilizer from accumulating in the casing 3 and clogging the casing 3.

[0027] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
