Description

Technical Field

[0001] This utility model relates to the field of rice plant protection technology, and in particular to a rice fertilization device for rice plant protection. Background Technology

[0002] As one of the world's most important food crops, rice requires a sufficient supply of nutrients to ensure high yield and quality. Fertilization is a crucial aspect of rice cultivation management, directly affecting the growth, development, yield, and quality of rice.

[0003] Authorization announcement number CN 221240820 U discloses a rice fertilization device for rice plant protection, including a storage box with a frame at the lower end. The upper sides of the frame are fixedly connected to the side walls of the storage box. The device is designed to spread fertilizer via a rotating spraying disc. However, it has shortcomings in actual application. The spraying range is easily affected by factors such as rotation speed, wind speed, and terrain, causing fertilizer to spread outwards and making precise control of the application point difficult. This uneven fertilizer distribution often results in excessive fertilizer in some areas of the field while insufficient fertilizer is applied in others, severely impacting fertilization effectiveness. It is unsuitable for scenarios requiring narrow-area, precise fertilization, such as row application or hole application in rice, and cannot meet the demands of modern agriculture for refined and targeted fertilization, thus limiting its widespread application in actual production. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention.

[0025] Reference Figures 1-4 As an embodiment of the present invention, a rice fertilization device for rice plant protection is provided, which includes a cart 1, and a spraying disc 2 for spraying fertilizer is provided at the center of the bottom of the cart 1.

[0026] Several baffles 3 are hinged to the bottom of the cart 1 and arranged in a circular array around the spraying disc 2. Each baffle 3 has an independent bidirectional screw 5 on its outer surface and at the bottom of the cart 1. A handwheel is located at the center of the bidirectional screw 5. A screw cylinder 4 is screwed onto each of the symmetrically helical threaded sections of the bidirectional screw 5. One screw cylinder 4 is hinged to the outer side of the baffle 3, and the other screw cylinder 4 is hinged to the bottom of the cart 1. The multiple baffles 3 are controlled by the rotation of the bidirectional screw 5 to rotate around the hinge point with the cart 1. The inner walls of the multiple baffles 3 form a guide. The cavity faces the fertilization area between the rows of rice paddies (e.g., strip application, hole application). After the operator adjusts the angle of multiple baffles 3 by turning the double-ended screw 5, the end positions of the baffles 3 will differ. These differences will allow them to form different shapes and cover different areas. At this time, the fertilizer sprayed by the application disc 2 can be guided by the inner wall of the baffles 3 and roll down from their ends to the fertilization area between the rows of rice paddies. This achieves the precise fertilization needs of rice, adapts to the planting density and row spacing requirements of different rice varieties, and avoids local over- or under-fertilization.

[0027] Both the horizontal and vertical cross-sections of the baffle 3 are arc-shaped, and the concave surfaces face the spraying disc 2. The arc-shaped baffle 3 can guide the sprayed fertilizer, allowing it to move along the concave surface of the baffle 3. The inner wall of the baffle 3 is provided with a pad 31 along its circumference. The pad 31 is made of flexible material, and when the baffle 3 rotates, the pad 31 always faces the spraying angle of the spraying disc 2. That is, no matter what angle the baffle 3 rotates to, the outer surface of the pad 31 covers the fertilizer spraying direction of the spraying disc 2, and the fertilizer can hit the pad 31. This prevents the fertilizer from being crushed into powder after hard contact with the baffle 31, and prevents the powdered fertilizer from not being left in the fertilization area of ​​the paddy field.

[0028] like Figure 2 and Figure 5As shown, a hopper 6 is installed on the cart 1, and an adjusting disc 7 is fixed inside the hopper 6. A rotating shaft 8 is rotatably mounted on the adjusting disc 7. A stirring blade is fixed to the top of the rotating shaft 8, and the bottom of the rotating shaft 8 is connected to the spraying disc 2. The cart 1 includes a drive shaft and wheels 11 installed at both ends of the drive shaft. A gear set 9 is provided between the drive shaft and the rotating shaft 8. The gear set 9 can be two meshing bevel gears or a meshing worm gear and worm, or other similar structures. The gear set 9 can transmit the rotation of the wheels 11 to the rotating shaft 8, thereby causing the stirring blade and the spraying disc 2 to rotate synchronously. The stirring blade stirs the fertilizer to prevent clumping, and the spraying disc 2 can throw the fertilizer outward.

[0029] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
