DETAILED DESCRIPTION

[0023] 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 the embodiments.

[0024] Reference Figure 1-Figure 5 A device for observing the dissolution phenomenon of compound organic fertilizer comprises a dissolving barrel 1, which is provided with a feed port and a discharge port, an observation port 2 is provided on the side of the dissolving barrel 1, a rotating shaft 3 is vertically installed in the dissolving barrel 1, and a driving assembly for driving the rotating shaft 3 to rotate is provided at the upper end of the dissolving barrel 1, the driving assembly comprises a driving motor 11 fixedly installed on the upper end of the dissolving barrel 1, a first spur gear 12 fixedly installed on the output shaft of the driving motor 11 and a second spur gear 13 fixedly sleeved on the rotating shaft 3, the first spur gear 12 is meshed with the second spur gear 13, and a plurality of rectangular plates 4 are symmetrically fixedly installed on the rotating shaft 3, and a plurality of rectangular plates 4 are provided with rectangular grooves at one end away from the rotating shaft 3, and a stirring plate 5 is slidably inserted in the plurality of rectangular grooves.

[0025] When dissolving organic fertilizer, organic fertilizer and water are added to the dissolving barrel 1, and then the driving motor 11 is started to drive the first spur gear 12 to rotate, and then the rotating shaft 3 is driven to rotate through the second spur gear 13. During the rotation of the rotating shaft 3, the plurality of rectangular plates 4 and the stirring plates 5 are driven to rotate around the rotating shaft 3. The rectangular plates 4 and the stirring plates 5 are in contact with the solution in the dissolving barrel 1 and stir it, thereby accelerating the dissolution rate of the organic fertilizer. During the dissolution process, personnel can observe the dissolution phenomenon of the organic fertilizer in the dissolving barrel 1 through the observation port 2.

[0026] Cross bars 6 are symmetrically and horizontally fixedly installed on the rotating shaft 3. A movable groove is provided at the end of the two cross bars 6 away from the rotating shaft 3. A movable rod 8 is slidably installed in the two movable grooves through a telescopic spring 7. A connecting rod 9 is fixedly installed at one end of the two movable rods 8. The two connecting rods 9 are respectively fixedly connected to the stirring plates 5 on both sides of the rotating shaft 3. A cylindrical groove is provided at the upper end of the rotating shaft 3, and an air inlet 10 connected to the cylindrical groove is provided at one end of the movable groove. An air injection component for injecting air into the cylindrical groove is provided at the upper end of the rotating shaft 3.

[0027] The air injection assembly can inject air into the cylindrical groove, and at the same time, the air in the cylindrical groove will enter the movable groove through the air inlet 10. As the air in the movable groove continues to increase, under pressure, it will push the movable rod 8 to move away from the rotating shaft 3, and the telescopic spring 7 will be stretched. During the movement of the movable rod 8, it will drive the multiple stirring plates 5 to move in the rectangular groove through the connecting rod 9. When the stirring plate 5 moves away from the rotating shaft 3, the contact area between the stirring plate 5 and the rectangular plate 4 and the solution during stirring will be increased. It is judged whether the contact area between the stirring plate 5 and the rectangular plate 4 and the solution during stirring is related to the dissolution rate of the organic fertilizer, and experimental data between the dissolution rate of the organic fertilizer and the contact area between the stirring plate 5 and the rectangular plate 4 and the solution during stirring are obtained, making the experiment diversified.

[0028] The gas injection assembly includes a gas injection cylinder 14 fixedly mounted on the upper end of the rotating shaft 3, a sealing plate 15 sealingly and slidingly mounted in the gas injection cylinder 14, a push-pull handle 16 fixedly mounted on the sealing plate 15, and an air inlet pipe 17 fixedly connected to the side of the gas injection cylinder 14. The gas injection cylinder 14 is connected to the cylindrical groove of the rotating shaft 3. A first one-way valve that only allows gas to enter the gas injection cylinder 14 is installed in the air inlet pipe 17. A second one-way valve that only allows gas to enter the cylindrical groove is installed at the connection between the cylindrical groove and the gas injection cylinder 14.

[0029] When air needs to be injected into the cylindrical groove, the sealing plate 15 can be driven to move up and down in the air injection cylinder 14 by pushing and pulling the handle 16. When the sealing plate 15 moves vertically downward, the sealing plate 15 will allow the air in the air injection cylinder 14 to enter the cylindrical groove. When the sealing plate 15 moves vertically upward, the outside air will enter the air injection cylinder 14 through the air inlet pipe 17. Therefore, through the continuous up and down movement of the sealing plate 15, air can be continuously injected into the cylindrical groove.

[0030] An exhaust pipe 18 connected to the cylindrical groove is installed on the side of the rotating shaft 3. A sealing plug 19 is inserted at one end of the exhaust pipe 18. When it is necessary to reduce the contact area between the rectangular plate 4 and the stirring plate 5 and the solution, the sealing plug 19 can be removed and the air in the movable groove can be discharged through the cylindrical groove. At this time, under the action of the elastic force of the telescopic spring 7, the movable rod 8 will drive the stirring plate 5 to move toward the rotating shaft 3.

[0031] A return spring 20 is fixedly installed on the lower surface of the sealing plate 15, and the lower end of the return spring 20 is fixedly connected to the inner wall of the gas injection cylinder 14. A block 21 is symmetrically fixedly installed on the inner wall of the gas injection cylinder 14. The two blocks 21 are located above the sealing plate 15. The return spring 20 causes the sealing plate 15 to have a vertical upward movement tendency until it contacts the block 21, thereby supporting the sealing plate 15 and preventing the sealing plate 15 from moving in the gas injection cylinder 14 during the rotation of the rotating shaft 3. The block 21 can prevent the sealing plate 15 from moving out of the gas injection cylinder 14.

[0032] In the present invention, the air injection component can inject air into the cylindrical groove, and at the same time, the air in the cylindrical groove will enter the movable groove through the air inlet 10. As the air in the movable groove continues to increase, under pressure, the movable rod 8 will be pushed to move in the direction away from the rotating shaft 3, and the telescopic spring 7 will be stretched. During the movement of the movable rod 8, the connecting rod 9 will drive the multiple stirring plates 5 to move in the rectangular groove. When the stirring plate 5 moves in the direction away from the rotating shaft 3, the contact area between the stirring plate 5 and the rectangular plate 4 and the solution during stirring will be increased. It is judged whether the contact area between the stirring plate 5 and the rectangular plate 4 and the solution during stirring is related to the dissolution rate of organic fertilizer, and experimental data between the dissolution rate of organic fertilizer and the contact area between the stirring plate 5 and the rectangular plate 4 and the solution during stirring are obtained, so that the experiment is diversified.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
