Description

Technical Field

[0001] This utility model relates to the field of corn topdressing technology, specifically a corn planting topdressing device. Background Technology

[0002] Corn is a crop with high fertilizer requirements, and its needs for nutrients such as nitrogen, phosphorus, and potassium change throughout its growth cycle. Topdressing can replenish the nutrients needed by corn at different growth stages, promote root development, thicker stems, lush leaves, and fuller ears, thereby improving yield and quality.

[0003] For example, a corn planting topdressing device with publication number CN222263614U has a main body with a conical cover at its bottom for inserting into the ground. The conical cover includes two symmetrically arranged outer shells. Because the outer shells are movably connected to the main body, they can open after being inserted into the ground, allowing fertilizer to flow out from the bottom of the main body, thus completing the topdressing. This patent requires the conical cover to be inserted into the ground and requires continuous force. A rotating rod drives the outer shells to open, and the outer shells compress holes in the ground, making operation inconvenient, continuous topdressing laborious, and the amount of fertilizer dispensed uncontrollable. To address these problems, this utility model proposes a corn planting topdressing device. Utility Model Content

[0004] The purpose of this invention is to provide a corn planting topdressing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corn planting topdressing device, comprising a feeding pipe with an open upper end and a conical pipe integrally formed and connected to the lower end of the feeding pipe, wherein the lower end of the conical pipe is an open structure, and a conical head that can move up and down is provided at the opening of the conical pipe. A hemispherical groove is provided at the lower end of the inner part of the feeding pipe, and a feeding port is provided between the lower end of the hemispherical groove and the inside of the conical head. A hemispherical part is integrally formed and connected to the upper end of the conical head, and a vertically arranged shaft is connected to the upper end of the hemispherical part. A sealing block located in the feeding port is provided between the shaft and the hemispherical part. A pressing rod with both ends movable through the feeding pipe is connected to the upper end of the shaft.

[0006] Preferably, the upper end diameter of the conical head is equal to the inner diameter of the opening of the conical tube.

[0007] Preferably, a second pressing rod is symmetrically connected to the upper side wall of the feeding tube, located at the lower end of the pressing rod, and a limiting groove is symmetrically provided on the upper side wall of the feeding tube, through which the first pressing rod passes.

[0008] Preferably, the two ends of the first pressing rod are symmetrically connected to a T-shaped shaft that is movably connected to the second pressing rod, and a return spring is connected between the lower end of the T-shaped shaft and the second pressing rod.

[0009] Preferably, the diameter of the sealing block is equal to the inner diameter of the discharge port.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model has a reasonable design, and the topdressing process can be completed with a simple pressing and releasing action. Compared with traditional topdressing methods, it does not require continuous force or complicated operations, which greatly improves fertilization efficiency and reduces the labor intensity of farmers.

[0012] 2. The conical head and sealing block in this invention are cleverly designed to ensure that the amount of fertilizer in the conical tube remains consistent each time fertilizer is applied. This helps to achieve equal application of fertilizer, meet the nutrient requirements of corn at different growth stages, and improve fertilizer utilization and efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-5As shown, this utility model provides the following technical solution:

[0021] Example 1: A corn planting topdressing device includes a feeding pipe 1 with an open upper end and a tapered pipe 11 integrally formed and connected to the lower end of the feeding pipe 1. The lower end of the tapered pipe 11 has an open structure, and a tapered head 2 that can move up and down is provided at the opening of the tapered pipe 11.

[0022] In use, fertilizer is added through the opening at the upper end of the discharge pipe 1. The discharge pipe 1 is inserted into the ground through the cooperation of the conical pipe 11 and the conical head 2, and the vertically movable conical head 2 opens the opening at the lower end of the conical pipe 11, allowing the fertilizer to fall into the corresponding cavity.

[0023] Example 2: The technical solution of this example, which differs from Example 1, includes: a hemispherical groove 12 is provided at the lower end of the feed tube 1; a feed port 13 is provided between the lower end of the hemispherical groove 12 and the interior of the conical head 2; an integrally formed hemispherical part 21 is provided at the upper end of the conical head 2; a vertically arranged shaft 22 is connected to the upper end of the hemispherical part 21; a sealing block 23 is provided between the shaft 22 and the hemispherical part 21, located inside the feed port 13; and a downward pressure rod 3, with both ends movably passing through the feed tube 1, is connected to the upper end of the shaft 22. The upper port diameter of the conical head 2 is equal to the inner diameter of the opening of the conical tube 11. A second pressing rod 14, located below the first pressing rod 3, is symmetrically connected to the upper side wall of the feeding pipe 1. A limiting groove 15 is symmetrically provided on the upper side wall of the feeding pipe 1. The first pressing rod 3 passes through the limiting groove 15, which limits its stroke, ensuring that the sealing block 23 seals the feeding port 13 when the first pressing rod 3 is at its uppermost position. T-shaped shafts 31, movably connected to the second pressing rod 14, are symmetrically connected to both ends of the first pressing rod 3. A return spring 32 is connected between the lower end of the T-shaped shaft 31 and the second pressing rod 14. The diameter of the sealing block 23 is equal to the inner diameter of the feeding port 13.

[0024] When using, such as Figure 3 and Figure 4 As shown, first, press down with both hands to bring the first pressing rod 3 into contact with the second pressing rod 14, while simultaneously pinching the first pressing rod 3 and the second pressing rod 14. This causes the shaft 22 and the conical head 2 to move downwards, and the sealing block 23 releases the discharge port 13. The fertilizer in the discharge pipe 1 enters the conical pipe 11 through the discharge port 13. Since the upper diameter of the conical head 2 is equal to the inner diameter of the opening of the conical pipe 11, the upper end of the conical head 2 seals the lower opening of the conical pipe 11. Then, insert the conical head 2 and the conical pipe 11 into the ground, and then release your hands. Under the elastic force of the return spring 32, the first pressing rod 3 is lifted back to its original position. Figure 1 and Figure 2In the initial state, the rising of the conical head 2 opens the opening at the lower end of the conical tube 11, and the fertilizer enters the conical hole in the ground. At the same time, the sealing block 23 rises to block the discharge port 13. The amount of fertilizer in the conical tube 11 is always the same each time fertilizer is applied, so as to achieve equal amount of fertilizer application. Fertilization is simple and does not require secondary force.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
