Description

Technical Field

[0001] This utility model relates to the field of paddy field fertilization technology, and in particular to a paddy field fertilizer spreading device. Background Technology

[0002] The process of rice paddy cultivation involves seven steps: land preparation, seedling raising, weeding and pest control, fertilization, irrigation and drainage, drying, and screening. Fertilization mainly refers to the agricultural technique of spreading fertilizer in the soil of the rice paddy to provide the nutrients needed by the plants and to maintain and improve soil fertility. The main purpose of fertilizer application is to increase crop yield, improve crop quality, enrich the soil, and improve economic benefits. Therefore, rational and scientific fertilization is one of the main means to ensure food security and maintain the sustainable development of agriculture.

[0003] Existing rice fertilization techniques require farmers to carry fertilizer while walking through the paddy fields, resulting in significant workload. One existing technology, such as the rice fertilization device disclosed in Chinese Utility Model Patent Publication No. CN218784096U, involves adding fertilizer to a container through a feeding port. A moving mechanism drives the container to move at a constant speed across the field, simultaneously activating a feeding mechanism and a driving mechanism. The feeding mechanism, assisted by the driving mechanism, transports the fertilizer from the container to a transition box. The driving mechanism, via multiple connecting rods, rotates the transition box, causing multiple first discharge conduits to rotate as well. The fertilizer in the transition box is then ejected through these rotating first discharge conduits, thus spreading it onto the field. While this patent solves the aforementioned problems, the upward conveying of fertilizer is not only prone to difficulties but also susceptible to clogging and residue buildup. Utility Model Content

[0004] To address the existing problems in rice fertilization techniques, such as the need for farmers to carry fertilizer while walking through paddy fields, which involves significant workload, and the difficulty of conveying fertilizer from bottom to top, as well as the issues of fertilizer blockage and residue, this invention proposes a paddy field fertilizer spreading device.

[0005] The technical solution of this utility model is: a paddy field fertilizer spreading device, including a fertilizer bin, the fertilizer bin has a structure that is open at both ends, the top of the fertilizer bin has a rectangular cylindrical structure, the bottom of the fertilizer bin has a conical structure with a horizontal cross section that gradually decreases from top to bottom, and a circular plate is fixedly provided at the bottom of the fertilizer bin, and a discharge port that is open at both ends and connected to the inside of the fertilizer bin is provided on the circular plate.

[0006] The bottom of the fertilizer silo is equipped with a spreading device for spreading the fertilizer output from the outlet. Specifically, two rods are fixedly installed on the fertilizer silo, spaced apart front to back and extending in the left-right direction. The rods are fixed to the fertilizer silo by U-shaped clamps. U-shaped frames with downward vertical orientation and upward opening are fixed on the rods. A fixing plate is fixed between the bottom ends of the two U-shaped frames. The spreading device includes a drive motor fixed on the fixing plate. A rotating plate is fixed on the output shaft of the drive motor. The outlet is located above the rotating plate.

[0007] Preferably, a fixing column is provided between the circular plate and the rotating plate. The fixing column is fixedly installed on the rotating plate. The rotating plate and the circular plate have the same structural size. The fixing column and the rotating plate are concentrically arranged. Multiple partitions are fixedly provided on the outer circumferential surface of the fixing column at intervals along its circumferential direction.

[0008] Preferably, the top of the fixed column is fixedly provided with an upwardly extending rotating rod, the top of the rotating rod passes through the discharge port and is inserted into the fertilizer bin, and multiple sets of levers are fixedly provided on the outer circumferential surface of the rotating rod, each set including multiple levers evenly distributed along the circumferential direction of the rotating rod.

[0009] Preferably, a square tube is fixedly provided at the left end of the two rods, and a connecting rod is hinged to the square tube and inclined from bottom to top and from right to left. The front end of the connecting rod is provided on the moving mechanism.

[0013] Advantages of this invention: This invention features a fertilizer silo with a rectangular cylindrical top and a tapered bottom that gradually decreases in horizontal cross-section from top to bottom. A spreading device is installed at the bottom of the silo, allowing fertilizer to be discharged from the outlet onto the surface of a rotating plate under gravity. Simultaneously, the rotating plate, driven by a motor, is thrown outwards by centrifugal force, achieving the purpose of spreading the fertilizer. Compared to manual spreading, this method is more efficient and uniform, suitable for large-scale production, and improves work efficiency. Compared to bottom-up conveying, this method uses gravity to transport fertilizer from top to bottom, resulting in a simpler structure.

[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] Example 1: A paddy field fertilizer spreading device, such as Figure 1-3 As shown, the device includes a fertilizer bin 1 for filling fertilizer. The fertilizer bin 1 has a vertically open structure. The top of the fertilizer bin 1 is a rectangular cylindrical structure to increase fertilizer storage capacity. The bottom of the fertilizer bin 1 is a conical structure with a gradually decreasing horizontal cross-section from top to bottom, allowing the fertilizer to move to the bottom of the fertilizer bin 1 under gravity. A circular plate 2 is fixedly installed at the bottom of the fertilizer bin 1. The circular plate 2 has a vertically open outlet that communicates with the interior of the fertilizer bin 1. A spreading device 3 is installed at the bottom of the fertilizer bin 1 to spread the fertilizer output from the outlet. Specifically, two rods 4 are fixedly installed on the fertilizer bin 1, spaced apart front to back and extending in the left-right direction. The fertilizer bin 1 is fixed with U-shaped clamps. For those skilled in the art, U-shaped clamps are well-known technology, so they will not be described in detail. A U-shaped rod frame 5 with a downward vertical orientation and an open structure is fixed on the rod 4. A fixing plate 6 is fixed between the bottom ends of the two U-shaped rod frames 5. The spreading device 3 includes a drive motor 31 fixed on the fixing plate 6. A rotating plate 32 is fixed on the output shaft of the drive motor 31. The discharge port is located above the rotating plate 32. The drive motor 31 can drive the rotating plate 32 to rotate, and the fertilizer output from the discharge port to the surface of the rotating plate 32 is thrown out in all directions by the centrifugal force generated by the rotation, so as to achieve the purpose of spreading fertilizer.

[0021] A fixing column 7 is provided between the circular plate 2 and the rotating plate 32. The fixing column 7 is fixed on the rotating plate 32. The rotating plate 32 and the circular plate 2 have the same structure and size. The fixing column 7 and the rotating plate 32 are concentrically arranged. Multiple partitions 8 are fixed on the outer circumferential surface of the fixing column 7 and are spaced apart along its circumferential direction. The partitions 8 divide the area between the circular plate 2 and the rotating plate 32 into multiple discharge zones, so that the fertilizer entering the rotating plate 32 from the discharge port can be evenly distributed, and the fertilizer thrown out from the rotating plate 32 is more uniform. At the same time, in a static state, the multiple discharge zones can prevent the material from overflowing the rotating plate 32 under the action of gravity.

[0022] The top of the fixed column 7 is fixedly provided with an upwardly extending rotating rod 9. The top of the rotating rod 9 passes through the discharge port and is inserted into the fertilizer bin 1. Multiple sets of vertically spaced levers 10 are fixedly provided on the outer circumference of the rotating rod 9. Each set includes multiple levers 10 evenly distributed along the circumference of the rotating rod 9. By driving the levers 10 to rotate, the rotating rod 9 can stir the fertilizer located at the bottom of the fertilizer bin 1, prevent fertilizer accumulation, blockage, and avoid affecting fertilizer application.

[0023] A square tube 11 is fixedly installed at the left end of the two rods 4. A connecting rod 12 is hinged to the square tube 11 and is inclined from bottom to top and from right to left. The front end of the connecting rod 12 is located on the moving mechanism, which is used to drive the fertilizer bin 1 to move in the paddy field for fertilizer spreading.

[0024] The bottom of the fertilizer bin 1 is a conical structure with a horizontal cross section that gradually decreases from top to bottom and tilts to the right. The circular plate 2 is located at the lower right of the fertilizer bin 1, and the spreading device 3 is located at the lower right of the fertilizer bin 1, so that the spreading device 3 is far away from the moving mechanism located at one end of the connecting rod 12, thus avoiding the moving mechanism from obstructing the spreading device 3 from spreading the fertilizer.

[0025] A fixing rod 13 extending upward is fixed on the square tube 11. The top end of the fixing rod 13 is fixed on the left side of the fertilizer bin 1 to prevent the center of gravity of the fertilizer bin 1 from shifting to the right due to the bottom tilting to the right, thereby increasing the stability of the structure.

[0026] The bottom of the fixed plate 6 is fixed with two downwardly extending support legs 14 spaced apart. The bottom ends of the two support legs 14 are equipped with rollers 15 that rotate through a rotating shaft. The rollers 15 are placed on the paddy field. The rollers 15 and the support legs 14 can provide support for the fertilizer bin 1 and the spreading device 3.

[0027] Working principle: Fertilizer is added into fertilizer bin 1. The moving mechanism drives fertilizer bin 1 and spreading device 3 to move in the paddy field. Under the action of gravity, the fertilizer enters multiple discharge zones from the discharge port at the bottom of fertilizer bin 1. At the same time, the drive motor 31 drives the rotating plate 32 and multiple partitions 8 to rotate, which throws the fertilizer in the multiple discharge zones to the surrounding areas through centrifugal force, spreading fertilizer to the surrounding paddy field. Meanwhile, the rotating plate 32 drives the rotating rod 9 and the lever 10 to rotate through the fixed column 7, which stirs the bottom area inside fertilizer bin 1, so that the fertilizer can move downward smoothly.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
