DETAILED DESCRIPTION
[0015] The utility model is further described below with reference to the accompanying drawings.
[0016] like Figure 1-Figure 3 A mounting plate 3 is fixed to one side below the lifting column 2, a hollow shaft motor 5 is mounted on the mounting plate 3, the upper part of the rotating shaft of the hollow shaft motor 5 is connected to the rotary joint 4, the upper part of the rotary joint 4 is connected to the enzyme liquid tank 1 through a hose 10, the lower part of the rotating shaft of the hollow shaft motor 5 is connected to the hollow rotating shaft 7 through a coupling 6, the lower part of the hollow rotating shaft 7 is connected to a hollow cross bar 8, and the lower part of the cross bar 8 is connected to a plurality of liquid outlet rods 9 with small holes.
[0017] A lifting motor 2-1 is provided on the upper inner side of the lifting column 2, and the lower part of the lifting motor 2-1 is connected to the screw rod 2-2. A nut 2-3 fixedly connected to the external structure is provided on one side of the lifting column 2, and the nut 2-3 is screwed with the screw rod 2-2. The lifting motor 2-1 drives the screw rod 2-2 to rotate, and the screw rod 2-2 and the nut 2-3 fixed to the external structure rotate relative to each other to realize the lifting and lowering of the lifting column 2. The external structure can be a fixed structure such as a fixed bracket or a top plate of a fermentation bin, or a stable moving structure such as a crane.
[0018] The bio-enzyme liquid tank 1 is fixed on the external structure outside the lifting column 2. The bio-enzyme liquid tank 1 can be fixed on a fixed support or a structure such as the top plate of the fermentation bin, and the liquid can flow out by gravity when the lifting column 2 is lowered to the bottom.
[0019] The rotary joint 4 is fixedly connected to the mounting plate 3 via the rotary joint bracket 3-1. The rotary joint bracket 3-1 fixes the rotary joint 4, and can prevent the rotary joint 4 from being damaged when the lifting column 1 is raised or lowered.
[0020] Both sides of the hollow shaft motor 5 are fixed on the mounting plate 3 through the motor bracket 3-2. The motor bracket 2-3 is used for the fixed installation of the hollow shaft motor 5.
[0021] A coupling bracket 3-3 is fixedly mounted on one side below the mounting plate 3, a thrust bearing 3-4 is arranged inside the coupling bracket 3-3, and a coupling 6 is mounted above the thrust bearing 3-4. The coupling bracket 3-3 supports the coupling 6 through the thrust bearing 3-4, thereby supporting the hollow shaft 7 below and the structure of the cross bar 8 and the liquid outlet rod 9, so that the shaft of the hollow shaft motor 5 will not bear the downward pulling force, and the hollow shaft 7 is easy to rotate.
[0022] When the utility model is used, the lifting motor 2-1 drives the screw rod 2-3 to rotate to make the lifting column 2 descend, and the liquid outlet rod 9 is inserted into the waste paper pile. The liquid outlet of the bio-enzyme liquid box is opened, and the liquid containing bio-enzyme in the bio-enzyme liquid box 1 passes through the hose 10, the rotary joint 4, the rotating shaft of the hollow shaft motor 5, the hollow rotating shaft 7, the cross bar 8, and the liquid outlet rod 9 in sequence, and finally flows out from the small hole of the liquid outlet rod 9. The hollow shaft motor 5 rotates, and drives the hollow rotating shaft 7 to rotate through the coupling 6, thereby driving the cross bar 8 and the liquid outlet rod 9 to rotate, stirring the waste paper pile while outputting the bio-enzyme liquid, and the bio-enzyme liquid is evenly distributed in the waste paper pile, which is convenient for fermentation. The rotary joint 4 prevents the hose 2 from rotating with the rotating shaft of the hollow shaft motor 5. After the bio-enzyme injection is completed, the hollow shaft motor 5 stops rotating, the liquid outlet of the bio-enzyme liquid box 1 is closed, and the lifting column 2 rises to retract the liquid outlet rod 9.
