[0023] A fixed sleeve plate 3 is fixedly connected to the top of the cooling tank 1, and a reciprocating dredging mechanism 4 is arranged on the front of the fixed sleeve plate 3. By arranging the reciprocating dredging mechanism 4, the fertilizer can enter more smoothly and evenly, thereby ensuring the uniform entry of the fertilizer and avoiding production fluctuations caused by uneven flow, and effectively preventing the fertilizer from accumulating and overflowing at the entrance.

[0024] The reciprocating dredging mechanism 4 includes a second motor 41, which is electrically connected to an external power supply and controlled by an external program. The second motor 41 is fixedly connected to the front side of the fixed sleeve 3, and the output end of the second motor 41 is fixedly connected to the first transmission bar 42, and the front side of the first transmission bar 42 is rotatably connected to the second transmission bar 43, and the front side of the second transmission bar 43 is rotatably connected to the connecting bar 44, and one side of the connecting bar 44 is fixedly connected to a connecting rod 45, and the connecting rod 45 and the fixed sleeve 3 are slidingly connected, and the bottom of the connecting rod 45 is fixedly connected to a dredging head 46, and the dredging head 46 is made of stainless steel.

[0028] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0029] The working principle of the utility model is as follows: first, put the fertilizer into the feed port 5, start the second motor 41, and rotate the first transmission bar 42 at its output end. The first transmission bar 42 drives the second transmission bar 43 while rotating, and the second transmission bar 43 drives the connecting rod 45 to slide up and down in the inner wall of the fixed sleeve 3 through the connecting bar 44. When the connecting rod 45 slides up and down, the dredging head 46 at the bottom thereof reciprocates up and down inside the feed port 5, and dredges the fertilizer, and then starts the pipeline 9 to allow the cooling medium inside the storage box 7 to pass through the pipeline. The first motor 21 is started to drive the connecting arm 23 at its output end to drive the three rotating shafts 24 on its inner wall to rotate along the inner wall of the cooling tank 1.
