Technical Field
[0001] This utility model relates to the field of fertilizer dissolution technology, specifically a fertilizer dissolution device for crop fertilization. Background Technology
[0002] A fertilizer dissolving device for crop fertilization is an agricultural device that is mainly used to mix solid or concentrated liquid fertilizers with water to form a uniform fertilizer solution. Such a device typically includes a container for storing fertilizer, a stirring system to promote fertilizer dissolution, and possibly a metering and control system to ensure precise fertilization.
[0003] By dissolving the fertilizer, it can be easily applied through the irrigation system, improving fertilizer utilization and reducing loss, thereby providing nutrients to crops more effectively, promoting crop growth, and optimizing farmland management.
[0004] Due to the release of gas from the surface of fertilizer granules or the introduction of air during the stirring process, air bubbles will float on them. These air bubbles can carry fertilizer granules to the surface, resulting in uneven distribution of fertilizer in the water and thus affecting the absorption of fertilizer by crops. Therefore, a fertilizer dissolving device for crop fertilization is proposed to address the above problems. Utility Model Content

[0027] Please see Figure 1-5 This utility model provides a technical solution:
[0028] A fertilizer dissolving device for crop fertilization includes a dissolving tank 1, a fixed support 2, and a drive motor 3. The fixed support 2 is bolted to the upper end of the dissolving tank 1. The drive motor 3 is fixedly connected to the middle of the upper end of the fixed support 2. A transmission mechanism 4 is fixedly connected to the top of the main shaft of the drive motor 3. An air bubble elimination mechanism 5 is installed on the outer side of the upper end of the transmission mechanism 4. A stirring blade 6 is fixedly connected to the bottom end of the transmission mechanism 4. A bottom groove 7 is opened in the middle of the bottom end of the dissolving tank 1. A filter screen 8 with an arc surface is installed on the inner side of the bottom end of the bottom groove 7. The transmission mechanism 4 includes a transmission shaft 41. A sliding groove 4 is opened on the outer side of the upper end of the transmission shaft 41. 2. A bottom blind hole 43 is provided at the bottom end of the drive shaft 41. Both sides of the upper end of the bottom blind hole 43 are provided with connecting holes 44 that communicate with the outside. A positioning post 48 is fixedly connected to the bottom end of the bottom blind hole 43. The outer side of the positioning post 48 is connected to the stirring rod 46 through a positioning through groove 47. A buoyancy block 45 is fixedly connected to the top end of the stirring rod 46. The bubble elimination mechanism 5 includes a crossbar 51. The crossbars 51 are fixedly connected to each other through a ring plate 54. An elastic scraper 53 is fixedly connected to the end of the crossbar 51 away from the ring plate 54. A number of sharp blocks 52 are fixedly connected to the bottom end of the crossbar 51. A slider 55 is welded and fixed inside the ring plate 54.
[0029] As a further implementation of this solution, a fertilizer pump 9 is fixedly connected to one side of the upper end of the fixed bracket 2. A water inlet pipe 10 is installed at the water inlet of the fertilizer pump 9, and the other end of the water inlet pipe 10 is installed at the lower end of the filter screen 8. Through the above settings, impurities in the fertilizer can be prevented from entering the fertilizer pump 9.
[0030] As a further implementation of this solution, two slide grooves 42 are provided inside the drive shaft 41. The slide grooves 42 are adapted to the slider 55. The slider 55 is slidably connected to the drive shaft 41 through the slide grooves 42. The ring plate 54 is slidably connected to the outer wall of the drive shaft 41. The ring plate 54 and the crossbar 51 are both hollow. Through the above settings, the stability of the bubble elimination mechanism 5 during the up and down movement can be guaranteed.
[0031] As a further implementation of this scheme, the connecting hole 44 is opened at the upper end of the stirring rod 46, and the connecting hole 44 is connected to the bottom blind hole 43. The positioning groove 47 is opened inside the stirring rod 46, and the bottom of the stirring rod 46 is arc-shaped. With the above settings, the water and fertilizer in the bottom groove 7 can be stirred in the later stage of fertilization.
[0032] As a further implementation of this solution, the buoyancy block 45 is set in the shape of a circular plate and is set inside the bottom blind hole 43. The bottom edge of the bottom blind hole 43 is arc-shaped. Through the above settings, the overall stability of the equipment during operation can be further improved.
[0033] As a further implementation of this solution, the included angle between the crossbar 51 and the elastic scraper 53 is 90°, and the crossbar 51 and the elastic scraper 53 correspond one-to-one. The end of the elastic scraper 53 away from the crossbar 51 is arc-shaped. Through the above settings, the cleanliness of the interior of the dissolving tank 1 can be improved by the elastic scraper 53.
[0034] As a further implementation of this scheme, the center points of the dissolving tank 1, the drive motor 3, the stirring blade 6, and the bottom trough 7 are set on the same vertical line, and the vertical cross section of the bottom trough 7 is trapezoidal. Through the above arrangement, the stability of the mixing of water and fertilizer inside the dissolving tank 1 by the stirring blade 6 can be further improved.
[0035] Work process: When the equipment is powered by an external power source, the process of dissolving fertilizer begins by pouring water and fertilizer into the dissolving tank 1. Then, the drive motor 3 is controlled to work, which drives the transmission shaft 41 to rotate, which in turn drives the stirring blades 6 to rotate, thus dissolving the fertilizer inside the dissolving tank 1. After dissolution, the water and fertilizer inside the dissolving tank 1 can be extracted by the fertilizer pump 9 for use in crop fertilization.
[0036] When there is a lot of water and fertilizer inside the dissolving tank 1, the stirring blades 6 continuously stir the water and fertilizer to prevent sedimentation and uneven mixing. During this process, the bubble elimination mechanism 5 floats on the surface of the water and fertilizer and rotates under the drive of the transmission shaft 41. During the rotation, the sharp block 52 can eliminate the surface bubbles generated during the stirring of water and fertilizer, effectively preventing the bubbles from carrying fertilizer particles to the surface and causing uneven distribution of fertilizer in the water, which affects the absorption of fertilizer by crops. The elastic scraper 53 treats the water and fertilizer adhering to the inner wall of the dissolving tank 1 at the edge of the water and fertilizer surface to prevent the water and fertilizer from adhering to the inner wall of the dissolving tank 1 and causing difficulties in cleaning later. During this process, the stirring rod 46 and the buoyancy block 45 are hidden inside the bottom blind hole 43 due to buoyancy.
[0037] When the water and fertilizer inside the dissolving tank 1 are low, the drive motor 3 restarts. The stirring rod 46 and the buoyancy block 45, which are hidden inside the bottom blind hole 43, move downwards under the influence of gravity, thus exposing the bottom of the stirring rod 46. At this time, under the influence of the rotation of the drive shaft 41, the stirring rod 46 forms a state with a certain angle to the drive shaft 41 and stirs the bottom of the dissolving tank 1. During this process, the water and fertilizer inside the bottom tank 7 can be stirred, thus preventing the stirring blades 6 from failing to stir when the water and fertilizer at the bottom of the dissolving tank 1 are low, which would lead to the problem of water and fertilizer sedimentation.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
