Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a farmland fertilization device. Background Art

[0002] The farmland fertilization device is a portable fertilization tool, mainly used for fertilization operations in farmland. This device is usually designed to be light and easy to use, making it convenient for farmers to work in the fields. This fertilization device can be easily carried on the back of farmers, making it convenient for them to move and work in the farmland. The fertilization device is suitable for fertilization operations of various crops, whether they are food crops or cash crops, and can be fertilized as needed. When using the backpack-type farmland fertilization device, farmers need to choose the appropriate type of fertilizer and amount of fertilizer according to the growth needs of crops and soil conditions.

[0003] The patent with the current publication number CN211297982U discloses an agricultural fertilizing device, wherein the upper part of the main body is a cover of the agricultural fertilizing device, the cover of the agricultural fertilizing device and the main body of the agricultural fertilizing device are connected by bolts, a second reinforcement block is provided on one side of the main body of the agricultural fertilizing device, and there are four second reinforcement blocks in total, a shoulder strap is provided on one side of the second reinforcement block, a first reinforcement block is provided on the other side of the agricultural fertilizing device, and there are two first reinforcement blocks in total, a telescopic pull rod is provided above the first reinforcement block, a handle is provided above the telescopic pull rod, a third reinforcement block is provided below the outer wall of the agricultural fertilizing device, and there are four third reinforcement blocks in total, and universal pulleys are provided below the third reinforcement blocks; although the above device solves the problem of sowing two fertilizers at the same time.

[0004] However, the above technical solution still has the following problems:

[0005] The farmland fertilization device cannot adjust the caliber of the fertilizer outlet when applying fertilizer. When fertilizer particles of different sizes pass through a fixed outlet caliber, there will be a large difference in flow rate. Large-particle fertilizer flows slowly, while small-particle fertilizer may pass quickly, resulting in uneven fertilization and affecting the crop's absorption of nutrients. The fixed outlet caliber cannot adjust the amount of fertilizer according to the size of the fertilizer particles, which may result in too much or too little fertilizer. Excessive fertilization not only wastes resources, but may also have a negative impact on crops and soil. Too little fertilization cannot meet the growth needs of crops. Since the outlet caliber cannot be adjusted, this fertilization device may only be suitable for fertilizers of a specific size. When fertilizers of different sizes need to be replaced, the entire fertilization device may need to be replaced or complex adjustments may be made, reducing the applicability and flexibility of the device.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] like Figures 1 to 5 As shown, a farmland fertilization device includes a box body 1 and a spraying assembly 2 connected to the box body 1, the spraying assembly 2 includes a sowing pipe 3 and an L-shaped connecting plate 4, the short side of the L-shaped connecting plate 4 is inserted into the open mouth of the sowing pipe 3, and a plug-in piece 6 is arranged in the short side of the L-shaped connecting plate 4, and the plug-in piece 6 and the short side of the L-shaped connecting plate 4 are fixedly connected by external bolts.

[0022] like Figure 1 As shown, a farmland fertilization device in the utility model is similar in structure to an existing agricultural fertilization device, such as the agricultural fertilization device disclosed in the patent publication number CN211297982U. The main improvement of the utility model is to improve the agricultural production efficiency and quality, such as Figures 1 to 5 As shown, when a farmland fertilization device in the utility model is in use, the box body 1 is used as a container for storing fertilizers, ensuring that the fertilizers can be smoothly transported to the spraying assembly 2 during the fertilization process, the spreading pipe 3 is a channel for fertilizer output, and the short side of the L-shaped connecting plate 4 is inserted into the open mouth of the spreading pipe 3. By controlling the L-shaped connecting plate 4, the opening degree of the spreading pipe 3 can be accurately controlled, thereby adjusting the spreading amount of the fertilizer. This precise fertilization can ensure that the crops obtain a suitable nutrient supply. By replacing the plug-in pieces 6 of different calibers, the fertilization device can adapt to fertilizer particles of different sizes and types, which ensures that the device can evenly and effectively spread various fertilizers to meet the needs of different crops and soil conditions.

[0023] like Figures 2 to 3 As shown, two symmetrically installed fixing ears 301 are fixedly connected to the outer side of the sowing pipe 3, a fixing shaft 302 is fixedly connected between the two symmetrical fixing ears 301, and a rotating ear 401 rotatably connected to the fixing shaft 302 is fixedly connected to the outer side of the L-shaped connecting plate 4.

[0024] Specifically, this arrangement ensures that the L-shaped connecting plate 4 is stably installed on the sowing pipe 3 by connecting the fixed shaft 302 between the fixed ear 301 and the rotating ear 401. At the same time, this rotating connection method allows the L-shaped connecting plate 4 to swing under the constraint of the fixed shaft 302, thereby conveniently controlling the opening switch of the sowing pipe 3 to achieve the adjustment of the fertilizer sowing amount.

[0025] like Figure 2 As shown, a return spring 5 is fixedly connected to the outer side of the L-shaped connecting plate 4 , and the other end of the return spring 5 is fixedly connected to the outer side of the sowing pipe 3 .

[0026] Specifically, through this setting, the reset spring 5 has the ability of automatic reset. When the external force disappears, it can push the L-shaped connecting plate 4 to return to the initial position, that is, the position where the sowing pipe 3 is closed. This means that when the user does not continue to operate, the sowing pipe 3 can be automatically closed to prevent accidental sowing of fertilizers, thereby improving the safety of fertilization operations.

[0027] like Figures 1 to 4 As shown, a sliding channel 303 is provided outside the open mouth of the spreading tube 3, the outer side of the short side of the L-shaped connecting plate 4 is slidingly connected to the inner wall of the sliding channel 303, and the sliding channel 303 is passed through the short side of the L-shaped connecting plate 4.

[0028] Specifically, through this arrangement through the sliding channel 303, the short side of the L-shaped connecting plate 4 can slide smoothly inside it. This design avoids the L-shaped connecting plate 4 from getting stuck or shaking during movement, allowing the user to control the opening degree of the sowing tube 3 more accurately.

[0029] like Figure 5 As shown, a slot 402 slidably connected to the plug-in piece 6 is provided at the top of the short side of the L-shaped connecting plate 4, a discharge port 403 connected to the slot 402 is provided on the surface of the short side of the L-shaped connecting plate 4, and a feed hole 601 aligned with the discharge port 403 is provided on the surface of the plug-in piece 6.

[0030] Specifically, by setting the slot 402, the connector 6 can be easily plugged in and out of the L-shaped connecting plate 4, and the user can easily replace the connectors 6 of different calibers to meet the needs of different fertilizer particle sizes or sowing amounts, thereby improving the flexibility and adaptability of the device. The discharge port 403 is aligned with the feed hole 601 on the connector 6, ensuring that the fertilizer particles can smoothly pass through the L-shaped connecting plate 4 and the connector 6 from the sowing pipe 3 and finally be sown into the farmland.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
