The bottom of the tank body 1 is provided with a fertilizer outlet 1-3 for outputting filtered fertilizers. Preferably, the bottom of the tank body 1 is fixedly provided with a water guide plate 1-4 for guiding water to the fertilizer outlet 1-3, which is beneficial to the complete discharge of the fertilizers.

[0037] The filter screen 2 has a cylindrical structure; it is located inside the tank 1 and coaxially distributed with the tank 1; the filter screen 2 is detachably mounted on the top of the tank 1; the water inlet 1-1 and the feed inlet 1-2 are located above the filter screen 2 to allow material to be added into the filter screen 2. The bottom of the filter screen 2 has a discharge channel; the discharge channel is connected to the discharge port 1-5 to discharge impurities from the filter screen 2.

[0038] The drive shaft 3 is vertically mounted inside the tank body 1 and rotatably connected to the tank body 1; the drive shaft 3 is connected to the tank body 1 via bearings. The drive shaft 3 can be connected to the top and bottom of the tank body 1; or it can be connected to the top and middle of the tank body 1, with a support frame installed in the middle. The drive device 4 is located at the top of the tank body 1 and is connected to the drive shaft 3 for transmission, capable of driving the drive shaft 3 to rotate forward or in reverse; the drive device 4 is a motor.

[0039] The filter cleaning mechanism 5 includes: a support 5-1, a first connecting plate 5-2, a second connecting plate 5-4, a cleaning seat 5-3, a cleaning brush 5-5, a rubber plate 5-6, and a limiting block 5-7. The support 5-1 is fixedly locked onto the drive shaft 3. The support 5-1 is located inside the filter screen 2. One end of the first connecting plate 5-2 is hinged to the support 5-1, allowing it to swing left and right relative to the support 5-1. The first connecting plate 5-2 has a through hole, which not only agitates the liquid inside the filter screen 2 but also reduces rotational resistance. One end of the second connecting plate 5-4 is hinged to the support 5-1, allowing it to swing left and right relative to the support 5-1. The second connecting plate 5-4 has a through hole, which not only agitates the liquid inside the filter screen 2 but also reduces rotational resistance. The second connecting plate 5-4 is parallel to the first connecting plate 5-2.

[0040] The cleaning seat 5-3 is hinged to the connecting plate 5-2 and the connecting plate 5-4 respectively; the support 5-1, the connecting plate 5-2, the connecting plate 5-4 and the cleaning seat 5-3 are constructed as a parallel four-bar structure so that the cleaning seat 5-3 can swing to the left or right relative to the support 5-1; preferably, there are at least two parallel four-bar structures constructed by the support 5-1, the connecting plate 5-2, the connecting plate 5-4 and the cleaning seat 5-3; the two parallel four-bar structures are symmetrically distributed with the drive shaft 3 as the center to increase cleaning efficiency and balance the force on the drive shaft 3.

[0041] The cleaning brush 5-5 is fixedly mounted on one side of the cleaning seat 5-3 and is used for cleaning the filter screen 2.

[0042] Rubber plate 5-6 is fixedly installed on the other side of cleaning seat 5-3 to clean filter screen 2 during normal operation and prevent filter screen 2 from clogging. Limiting block 5-7 is fixedly installed on support 5-1, located between connecting plate one 5-2 and connecting plate two 5-4, to limit the swing range of connecting plate one 5-2 and connecting plate two 5-4 to a suitable angle;

[0043] When the drive unit 4 drives the drive shaft 3 to rotate forward, the connecting plate 5-2 and the connecting plate 5-4 will be resisted by the liquid fertilizer and sway in one direction. At this time, the distance between the cleaning brush 5-5 and the rubber plate 5-6 and the drive shaft 3 will change, causing one of the cleaning brush 5-5 and the rubber plate 5-6 to be farther away from the drive shaft 3, so that it can contact the inner surface of the filter screen 2 and clean the filter screen 2. When the drive unit 4 drives the drive shaft 3 to rotate in reverse, the connecting plate 5-2 and the connecting plate 5-4 will be resisted by the liquid fertilizer and sway in the other direction, causing the other of the cleaning brush 5-5 and the rubber plate 5-6 to be farther away from the drive shaft 3, so that it can contact the inner surface of the filter screen 2 and clean the filter screen 2. The cleaning of the filter screen 2 under different conditions can be controlled by the forward and reverse rotation of the drive unit 4, which is convenient to use and can prevent the filter screen 2 from clogging.

[0044] The stirring blade 6 is fixedly mounted on the drive shaft 3, located below the filter screen 2; the stirring blade 6 has through holes 3, so as to reduce the resistance experienced by the stirring blade 6 while stirring the fertilizer.

[0045] One embodiment of this utility model provides a fertilizer tank that can prevent filter clogging and improve fertilization effect.
