Detailed Implementation

[0026] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0027] Please see Figures 1 to 8 This embodiment provides a double-row fertilization and ridging device, which includes a rotary tillage unit and a fertilization unit.

[0028] The rotary tillage unit includes a rotary tiller frame 11, a transmission mechanism 12 mounted on the rotary tiller frame 11, a rotating shaft 13 rotatably mounted at the bottom of the rotary tiller frame 11, and rotary tillage blades 14 spaced apart on the rotating shaft 13. The rotating shaft 13 is arranged laterally. The transmission mechanism 12 is poweredly connected to the rotating shaft 13. In use, the rotary tiller frame 11 is connected to the tractor (connection components are not shown). The transmission mechanism 12 is also connected to the tractor's power shaft. Thus, when the tractor moves, the rotary tillage blades 14 can loosen the soil in the field. Since the rotary tillage assembly is a standard accessory for rotary tillers, it will not be described in detail.

[0029] The fertilization unit includes a fertilizer box 21 mounted on a rotary tiller 11, a fertilizer pipe 22 installed at the bottom of the fertilizer box 21, a fertilizer dispensing shaft 23 rotatably installed between the fertilizer box 21 and the fertilizer pipe 22, and a drive mechanism 24 poweredly connected to the fertilizer dispensing shaft 23. The drive mechanism 24 can be a drive motor, which drives the rotation of the fertilizer dispensing shaft 23. The fertilizer dispensing shaft 23 is located at the bottom of the fertilizer box 21 and is provided with fertilizer troughs 25 spaced circumferentially. Fertilizer enters into the fertilizer troughs 25. When the fertilizer troughs 25 rotate to the bottom, the fertilizer falls out from the fertilizer troughs 25 into the fertilizer pipe 22. The lower end of the fertilizer pipe 22 is located at a predetermined position in front of the rotary tiller blade 14, thereby guiding the fertilizer to the position in front of the rotary tiller blade 14, where it is then agitated and mixed with the soil by the rotary tiller blade 14, thus achieving fertilization.

[0030] By combining the rotary tillage unit and the fertilization unit, fertilization and rotary tillage ridging operations can be linked together, enabling simultaneous fertilization, rotary tillage and ridging operations, accelerating the ridging process and reducing ridging costs.

[0031] For ease of operation, the device also includes an arc-shaped ridging plate 15 installed behind the rotary tiller 11. The ridging plate 15 is vertically adjustable on the rotary tiller 11 via a bracket 16. After the rotary tiller blades 14 loosen the soil, the arc-shaped ridging plate 15 can shape the soil into ridges.

[0032] To improve efficiency, the ridging plates 15 are arranged in two sets at intervals, and there are two corresponding fertilizer pipes 22. The fertilizer pipes 22 are installed on the rotary tiller 11 in front of the corresponding sets of ridging plates 15, so that fertilization and ridging operations of two ridges can be carried out at one time, which greatly improves the work efficiency.

[0033] To improve the effect, an arc-shaped scraper 17 is installed between the ridging plates 15. The lower part of the scraper 17 is provided with an arc-shaped opening 18, and the top of the scraper 17 and the area between the ridging plates 15 are provided with a mud-blocking plate 19. The scraper 17 corresponds to the furrow position. Through the combination of the scraper 17 and the mud-blocking plate 19, the soil can be guided to both sides as much as possible, while a small amount of soil is discharged through the arc-shaped opening 18, which can make the ridge more full and well-shaped.

[0034] For ease of operation, the fertilizer box 21 is funnel-shaped with a larger top and a smaller bottom. The fertilizer box 21 is equipped with a partition 26 to divide the fertilizer box 21 into two cavities. The bottom two sides of the fertilizer box 21 are provided with fertilizer dispensing cavities 27. The two sides of the fertilizer dispensing shaft 23 can be rotatably installed in the fertilizer dispensing cavities 27.

[0035] For ease of operation, a driven sprocket 28 is installed in the middle of the fertilizer dispensing shaft 23, and a driving sprocket 29 is installed on the output shaft of the drive motor. The driving sprocket 29 and the driven sprocket 28 are connected by a transmission chain 30, so that the drive motor can synchronously drive the rotation of the fertilizer dispensing shafts 23 on both sides. The switch and speed button of the drive motor can be set on the tractor for manual operation.

[0036] For ease of operation, a slide rail 31 is provided at the front end of the rotary tiller 11 along its width direction. A sliding seat 32 is installed on the slide rail 31. The sliding seat 32 can be adjusted and fixed along the slide rail 31. The lower end of the fertilizer pipe 22 is installed on the sliding seat 32, so that the position of the fertilizer pipe 22 can be adjusted according to the fertilization needs.

[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
