[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model provides a technical solution: a corn planting topdressing device, including a main body 1, such as Figure 1 As shown, the main body 1 is a tubular structure, and both the upper and lower ends are open. A conical cover is provided at the bottom of the main body 1, and the conical cover can be used to cone into the ground to complete the topdressing. The conical cover includes two symmetrically arranged shells 2, and the bottoms of the two shells 2 are conical. The shells 2 are movably arranged at the bottom of the main body 1, as shown in FIG. Figure 2 As shown, in normal state, the two shells 2 are fitted together, so that the bottom of the main body 1 is in a closed state, which is the first state of the device. When the cone is inserted into the ground, as shown in FIG. Figure 3 As shown, the control housing 2 is moved away so that the bottom of the main body 1 is opened. This is the second state of the device. The fertilizer in the main body 1 can fall into the hole formed by the conical cover to complete the topdressing.

[0022] Specifically, the bottom side wall of the main body 1 is provided with a strip-shaped through groove 3, such as Figure 2 As shown, the strip through groove 3 extends in the same direction along the length direction of the main body 1, and the inner surface of the shell 2 is fixedly connected with a connecting piece 13. The inner surface of the strip through groove 3 is rotatably provided with a rotating rod 4. There are two rotating rods 4 in each of the strip through grooves 3. The two rotating rods 4 are arranged in parallel, and one end of the rotating rod 4 away from the corresponding strip through groove 3 is movably connected to the connecting piece 13 respectively. Therefore, the shell 2 is in a translational state when opened, which can expand the hole while ensuring that the fertilizer in the main body 1 can fall into the hole, so that the effect of topdressing is better.

[0023] Specifically, the rotating rod 4 is coaxially connected with a transmission gear 5 at one end corresponding to the strip through groove 3, and the transmission gear 5 is coaxially arranged with the corresponding rotating rod 4. A movable rod 6 is movably arranged inside the main body 1, and the outer circumferential surface of the movable rod 6 is in contact with the inner circumferential surface of the main body 1 to ensure that the movable rod 6 can slide smoothly inside the main body 1. The outer circumferential surface of the movable rod 6 is provided with a strip groove 7 corresponding to the strip through groove 3, and the strip groove 7 extends in the same direction along the length direction of the movable rod 6. A rack 8 is provided on the inner surface of the strip groove 7, and the transmission gear 5 is meshed with the rack 8. An elastic element is provided between the movable rod 6 and the main body 1. Under the action of the elastic element, the movable rod 6 has a tendency to move away from the outer shell 2. Under this tendency, the rack 8 drives the transmission gear 5, so that the transmission gear 5 drives the outer shell 2 to close through the corresponding rotating rod 4. When inserted into the ground, a force is applied to the movable rod 6. Under this stress, the movable rod 6 overcomes the elastic element and slides relative to the main body 1, driving the outer shell 2 to open, thereby completing topdressing.

[0024] Specifically, a movable ring 9 is sleeved and screwed on the outer circumference of the movable rod 6, and the elastic element is a spring. The elastic element is sleeved on the outside of the movable rod 6, and the two ends of the elastic element are respectively in contact with the movable ring 9 and the main body 1. Under the action of the elastic element, the movable rod 6 tends to move away from the outer shell 2. The distance between the movable ring 9 and the main body 1 can be controlled by rotating the movable ring 9 to adjust the prestress of the elastic element, so that the elastic element can be reasonably adjusted according to the soil conditions. After the equipment is inserted into the ground, the movable rod 6 can slide relative to the main body 1 and overcome the elastic element to control the opening of the outer shell 2, thereby preventing the equipment from being inserted too deeply into the outer shell 2 and being unable to open, or the outer shell 2 opens before being inserted into the ground, causing the fertilizer to fall outside the soil.

[0025] Specifically, the outer peripheral surface of the bottom of the movable rod 6 is fixedly connected to the limiting ring 10 , and the limiting ring 10 is tightly fitted to the bottom of the main body 1 , so as to facilitate the adjustment of the position of the limiting ring 10 .

[0026] Specifically, the outer circumference of the shell 2 is fixedly connected to the limit plate 11. After the shell 2 is inserted into the ground, the limit plate 11 contacts the ground, so that the movable rod 6 can overcome the elastic element and move relative to the main body 1, so as to control the topdressing depth.

[0027] Specifically, a handle 12 is fixedly connected to the outer peripheral surface of the upper end of the movable rod 6, which is convenient for holding the movable rod 6 and controlling the equipment to apply fertilizer.

[0028] When the utility model is used, fertilizer is injected into the equipment from the top of the movable rod 6, the handle 12 is held, the equipment is inserted into the ground, and the conical cover composed of the outer shell 2 is inserted into the ground, and then under the action of stress, the movable rod 6 overcomes the elastic element to slide relative to the main body 1, so that the rack 8 moves relative to the transmission gear 5, the transmission gear 5 rotates, and drives the rotating rod 4 to rotate, and the outer shell 2 is driven to open by the rotating rod 4, and the fertilizer located in the main body 1 can fall into the inside of the cone hole.
