A connecting block 13 is provided on the side of the first threaded groove 17. A second threaded groove 14 passes through the side of the connecting block 13. A screw 15 of matching size is movably connected inside the second threaded groove 14. Two L-shaped support columns 21 are provided at both ends of the housing 1. In this utility model, the motor, spring, threaded groove and screw column are all prior art and will not be described in detail. The motor is directly controlled by energizing the switch.

[0018] The limiting device 4 includes a first connecting plate 41, a second connecting plate 43 between the first connecting plate 41 and the top plate 3, a second moving groove 42 passing through the middle of the first connecting plate 41, a third connecting plate 44 movably connected inside the second moving groove 42, a third moving groove 45 passing through the lower end of the first connecting plate 41 near the motor 18, a first limiting block 46 of the same size movably connected inside the third moving groove 45, a moving block 48 movably connected to the upper end of the third connecting plate 44, a second limiting block 410 of the same height movably connected to both ends of the moving block 48, a handle 49 above the moving block 48, and several springs 47 between the side of the third connecting plate 44 away from the first limiting block 46 and the second moving groove 42.

[0019] The third connecting plate 44 includes a plate body 441. The plate body 441 is provided with a sliding groove 442 on the side near the moving block 48. Both ends of the sliding groove 442 are provided with second limiting grooves 443 of the same length. The second limiting block 410 is movably connected to the inside of the second limiting groove 443 and the two are of the same size. One end of the moving block 48 is movably connected to the inside of the sliding groove 442 and the two are of the same size. The moving block 48 can slide up and down inside the sliding groove 442. When the first limiting block 46 is located inside the second moving groove 42, the moving block 48 is located inside the second moving groove 42. When the first limiting block 46 is located inside the first limiting groove 7, the moving block 48 is located above the second moving groove 42.

[0020] The first connecting plate 41 is movably connected to the inside of the first moving groove 6 and the two are of the same size. The height of the third connecting plate 44 is greater than the height of the first connecting plate 41. The third moving groove 45 is located on the side of the first limiting groove 7. The first limiting block 46 is movably connected to the side of the first limiting groove 7 and the two are of the same size. The first connecting plate 41 is fixed to the side of the top plate 3 through the second connecting plate 43. When the first limiting block 46 enters the inside of the second moving groove 42, the moving block 48 will fall into the inside of the second moving groove 42. At this time, the size of the moving block will prevent the first limiting block 46 from moving out of the third moving groove.

[0021] The rotating shaft 19 and the stirring shaft 20 are movably connected inside the mixing tank 2. The bottom plate 12 is located below the stirring shaft 20. The top plate 3 has holes for connecting the rotating shaft 19 and the motor 18.

[0022] The first fixing plate 10 and the second fixing plate 11 are located on both sides of the base plate 12, and all three have the same length and height. The length of the limiting plate 16 is greater than the length of the second fixing plate 11.

[0023] The first threaded groove 17 is located on the side of the second threaded groove 14 and the threads of the two are the same. The screw 15 is movably connected inside the first threaded groove 17 and the threads of the two are matched.

[0024] The connecting block 13 is connected to the housing 1. The first fixing groove 8 and the second fixing groove 9 are located on the same horizontal line. The first fixing groove 8 is tightly and movably connected to the first fixing plate 10, and the second fixing groove 9 is tightly and movably connected to the second fixing plate 11.

[0025] Working Principle: In use, the first fixing plate 10, the base plate 12, and the second fixing plate 11 are firstly inserted into the first fixing groove 8, the mixing groove 2, and the second fixing groove 9 respectively through the second fixing groove 9, aligning the first threaded groove 17 and the second threaded groove 14 on the side of the limiting plate 16. Then, screws 15 are screwed into the second threaded groove 14 and the first threaded groove 17 respectively, fixing the base plate 12 to the lower end of the mixing groove 2. Next, the nutrients to be mixed are poured into the mixing groove. Then, the third connecting plate 44 on the limiting devices 4 on both sides of the top plate is moved away from the motor 18, causing the first limiting block 46 to enter the second moving groove 42. At this time, the moving block 48 falls into the second moving groove 42 through the sliding groove 442 and the second limiting groove 443, thus aligning the first limiting block 46. The top plate 3 is then aligned with the housing 1, allowing the stirring shaft and rotating shaft 19 to enter the mixing tank. The limiting device 4 also enters the first moving groove 6. The handle 49 on the limiting device 4 is then moved upwards, causing the moving block 48 to move out of the second moving groove 42. The spring 47 causes the third connecting plate 44 to move the first limiting block 46 out of the second moving groove 42, allowing the first limiting block 46 to enter the first limiting groove 7, thus fixing the position of the top plate 3. The motor is then started to drive the stirring shaft 20 to mix the nutrients. After mixing, the bottom plate 12 can be moved out of the mixing tank to collect the nutrients through reverse operation. The top plate is then disassembled, and the stirring shaft, bottom plate, and inside the mixing tank are cleaned to facilitate the next nutrient mixing, preventing contamination from previous nutrient residues during mixing.
