[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0017] The specific technical solution of this utility model is as follows:

The rotating drive mechanism includes a vertical feed hole 52 on the upper turntable 42 and connected to the top of the retractable storage cylinder 6, a discharge port 21 (the discharge port 21 is a vertical through hole) on the bottom plate of the storage cylinder 2 and connected to the feed hole 52, a vertical discharge hole 51 on the lower turntable 41 and connected to the bottom of the retractable storage cylinder 6, a dropping port 31 (the dropping port 31 is a vertical through hole) on the lifting plate 3 and connected to the discharge hole 51, a vertical dropping pipe 32 whose top is fixed to the bottom surface of the lifting plate 3 and connected to the dropping port 31, and a vertical compression spring 9 whose bottom is fixed to the top surface of the lower turntable 41 and whose top is fixed to the bottom surface of the upper turntable 42.

[0019] The lifting drive mechanism includes: a vertical hydraulic cylinder 33 whose telescopic end is fixedly connected to the bottom surface of the lifting plate 3, and a connecting frame 34 that fixes the hydraulic cylinder 33 to the bottom end of the guide sleeve 11.

[0020] The retractable storage cylinder 6 includes: a vertical outer cylinder 61 whose bottom end is fixedly connected to the lower turntable 41, and a vertical inner cylinder 62 whose top end is fixedly connected to the upper turntable 42, whose bottom end is inserted into the outer cylinder 61 and slidably cooperates with the outer cylinder 61.

[0021] The rotary drive mechanism includes: a motor 71 mounted on the top surface of the top plate of the storage tank 2; a vertically mounted rotating shaft 72 mounted in the storage tank 2, with its top end penetrating through the top plate of the storage tank 2 and fixedly connected to the motor 71, and its bottom end penetrating through the bottom plate of the storage tank 2 and fixedly connected to the top surface of the upper turntable 42; and a vertically mounted telescopic connecting shaft 8 with its top end fixedly connected to the bottom surface of the upper turntable 42 and its bottom end fixedly connected to the top surface of the lower turntable 41; the telescopic connecting shaft 8 includes: a vertically mounted bushing 81 with its bottom end fixedly connected to the top surface of the lower turntable 41 and having a vertical square hole inside; and a vertically mounted square rod-shaped shaft 82 with its top end fixedly connected to the bottom surface of the upper turntable 42 and its bottom end inserted into the square hole of the bushing 81 and slidingly engaged with the square hole.

[0022] The lower turntable 41, the retractable connecting shaft 8, and the upper turntable 42 are all coaxial with the rotating shaft 72; the discharge port 21 and the discharge port 31 are respectively located on the left and right sides of the retractable connecting shaft 8; the compression spring 9 is fitted around the retractable connecting shaft 8; and the rotating shaft 72 is also equipped with a stirring rod 73.

[0023] The working principle of this utility model soil fertilizer application device includes:

[0024] The storage bin 2 contains fertilizer; during the movement of the movable frame 1, the motor 71 drives the upper turntable 42 to rotate through the rotating shaft 72, and the upper turntable 42 drives the lower turntable 41 to rotate synchronously through the telescopic connecting shaft 8, and the telescopic storage bin 6 rotates synchronously with the upper turntable 42 and the lower turntable 41.

[0025] Whenever the feed hole 52 of the upper turntable 42 rotates to align with the discharge port 21 of the bottom plate of the storage tank 2, the fertilizer in the storage tank 2 will enter the retractable storage cylinder 6 through the discharge port 21 and the feed hole 52. At this time, the discharge hole 51 of the lower turntable 41 is closed by the lifting plate 3, and the fertilizer entering the retractable storage cylinder 6 will be temporarily stored in the retractable storage cylinder 6.

[0026] When the feed hole 52 of the upper turntable 42 continues to rotate until it is misaligned with the discharge port 21 of the bottom plate of the storage tank 2, the discharge port 21 will be closed by the upper turntable 42; and before the discharge hole 51 of the lower turntable 41 rotates to connect with the discharge port 31 of the lifting plate 3, the discharge hole 51 will always be closed by the lifting plate 3, and the fertilizer in the telescopic storage cylinder 6 will rotate with the telescopic storage cylinder 6.

[0027] Whenever the discharge hole 51 of the lower turntable 41 rotates to align with the discharge port 31 of the lifting plate 3, the fertilizer temporarily stored in the retractable storage cylinder 6 will fall and be output through the discharge hole 51, discharge port 31, and discharge pipe 32, thereby achieving quantitative output of fertilizer.

[0028] The amount of fertilizer output is determined by the size of the inner cavity of the retractable storage cylinder 6; when it is necessary to adjust the amount of fertilizer output, the lifting plate 3 is driven to move up or down by the hydraulic cylinder 33.

[0029] When the lifting plate 3 moves upward, the lower turntable 41 moves upward synchronously with the lifting plate 3. The upward movement of the lower turntable 41 will vertically compress the retractable connecting shaft 8, the compression spring 9, and the retractable storage cylinder 6, making the inner cavity of the retractable storage cylinder 6 smaller, thereby reducing the amount of fertilizer quantitatively output.

[0030] When the lifting plate 3 moves down, the compression spring 9 extends vertically and drives the lower turntable 41 to move down synchronously with the lifting plate 3 (the compression spring 9 is always in a compressed state). The downward movement of the lower turntable 41 will vertically lengthen the telescopic connecting shaft 8 and the telescopic storage cylinder 6, making the inner cavity of the telescopic storage cylinder 6 larger, thereby increasing the amount of fertilizer quantitatively output.

[0031] In addition, a stirring rod 73 is provided on the rotating shaft 72. During the rotation of the rotating shaft 72, the stirring rod 73 can stir the fertilizer in the storage tank 2.

[0032] As can be seen from the above, the soil fertilizer application device of this utility model can quantitatively output fertilizer in the storage tank 2, so that the amount of fertilizer output each time is equal, thus achieving the effect of quantitative fertilization; it can also adjust the amount of fertilizer output according to actual needs, making it more practical.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
