Description

Technical Field

[0001] This utility model belongs to the field of fertilization technology, specifically a fertilization device for winter wheat cultivation. Background Technology

[0002] Fertilization in winter wheat cultivation is a comprehensive management process. It aims to meet the nutrient requirements of wheat at different growth stages, promote healthy growth and increase yield, improve soil organic matter content, and enhance soil structure.

[0003] For example, utility model application CN202220934429.8 discloses a winter wheat fertilization device, including a base with four rotatable wheels mounted at the bottom corners. A fertilizer box with an open top is fixedly connected to the top left of the base, and a lid is fixedly connected to the top of the fertilizer box. A battery is fixedly connected to the top right of the base, and a tillage mechanism is embedded in the bottom right of the base. The bottom inner wall of the fertilizer box has a conical structure, and a discharge pipe is connected and fixed to the bottom of the fertilizer box, with the bottom end of the discharge pipe extending to the bottom of the base. This utility model facilitates automatic mixing of fertilizer before fertilization, eliminating the need for manual mixing. It also facilitates automatic tamping and unblocking of the discharge pipe during fertilization, effectively reducing the risk of blockage and improving discharge stability. Furthermore, it facilitates soil tillage after fertilization, eliminating the need for manual tillage, thus improving work efficiency and meeting usage requirements.

[0004] The above-mentioned device clears the discharge pipe while mixing and stirring, reducing the risk of blockage during fertilization. However, the structure of the mixing area is relatively conventional, and there is no corresponding anti-blockage structure at the discharge port. This will cause granular fertilizer to easily accumulate at the discharge port due to the mixing inside the fertilizer box, resulting in blockage and affecting the fertilization operation. Therefore, it needs to be improved. Utility Model Content

[0040] Extrusion assembly 7 is located in the annular cavity.

[0041] Using the above scheme: in combination Figure 3 And Figure 4 The specific position of annular cavity can be clearly seen, and the setting of annular cavity provides good reserved space for the placement and movement process of extrusion assembly 7, and when limiting plate 72 is driven by external force to move rubber plate 73 to the side close to silica gel elastic film 6, it will abut silica gel elastic film 6 to make silica gel elastic film 6 deform.

[0042] As shown in Figure 3As shown, the outer wall of the one end of the pipe body 31 below the box body 21 is fixedly connected with the first spur gear 32, the outer wall of the first spur gear 32 is engagedly connected with the power assembly 4, and the top end of the pipe body 31 is movably clamped in the inside of the lower end of the box body 21.

[0043] As shown in the Figure 3 The power assembly 4 comprises a servo motor 41, the outer wall of the output shaft of the servo motor 41 is fixedly sleeved with a second spur gear 42, and the second spur gear 42 is engagedly connected with the first spur gear 32.

[0052] The working principle and use process of the utility model are as follows:

[0053] When the granular fertilizer needs to be discharged, the output end of the servo motor 41 is positively rotated, the second spur gear 42 is engaged with the first spur gear 32, the pipe body 31 is driven to rotate, the push rod 33 on the top of the pipe body 31 is in contact with the limiting plate 72, the limiting plate 72 and the rubber plate 73 are continuously pushed by the oblique angle end of the push rod 33 and are moved towards the silica gel elastic film 6, the longer protrusions on the rubber plate 73 press the silica gel elastic film 6, the silica gel elastic film 6 is deformed locally, the silica gel elastic film 6 is pressed by the plurality of rubber plates 73, the side of the silica gel elastic film 6 is deformed, the area of the granular fertilizer placed at the lower end of the inner cavity of the fertilizer storage box 2 is pressed, and the granular fertilizer is prevented from being blocked.

[0054] When the output end of the servo motor 41 is reversely rotated, the pipe body 31 is reversely rotated by the first spur gear 32, the push rod 33 is gradually separated from the limiting plate 72, the limiting plate 72 and the rubber plate 73 are driven away from the silica gel elastic film 6 by the spring telescopic cylinder 71, and the silica gel elastic film 6 is gradually reset.

[0055] The positive and reverse rotation of the output shaft of the servo motor 41 makes the pipe body 31 swing back and forth, the limiting plate 72 and the rubber plate 73 press, release, press and release the silica gel elastic film 6, and the anti-blocking effect of the granular fertilizer falling into the area at the lower end of the inner cavity of the fertilizer storage box 2 is improved.
