Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Example 1, please refer to Figures 1 - 4 , an aeration device for agricultural organic fertilizer fermentation, including: Fermentation tank 100, the top of the fermentation tank 100 is provided with a closable feeding port 200, a filter plate 300 is assembled inside the fermentation tank 100, and a liquid discharge port 600 is assembled on the side of the fermentation tank 100; Air pump 400, the air pump 400 is assembled at the side position of the fermentation tank 100, and an air delivery pipeline 500 is assembled on the top of the air pump 400; The inner wall of the fermentation tank 100 is assembled with a fixing plate 901, the inside of the fixing plate 901 is rotatably connected with a penetrating first rotating rod 902, the inside of the fermentation tank 100 is rotatably connected with a penetrating second rotating rod 906, and a transmission member for transmission is assembled between the first rotating rod 902 and the second rotating rod 906. The transmission member includes a wind wheel 903 fixed to the bottom of the first rotating rod 902, the wind wheel 903 is located on the side of the air delivery pipeline 500, and in the enabled state of the device, the wind wheel 903 is in a rotating state. The material is put into the fermentation tank 100 through the feeding port 200. At this time, the material is located on the filter plate 300. The air pump 400 is started to introduce the required gas into the fermentation tank 100. At this time, the fast-flowing gas drives the wind wheel 903 to rotate, so that the wind wheel 903 drives the first rotating rod 902 fixedly connected to the wind wheel 903 to rotate.

[0022] A sprocket wheel one 904 is fixedly connected to the outer side of the rotating rod one 902. A chain one 905 is assembled on the outer side of the sprocket wheel one 904. One end of the chain one 905 away from the sprocket wheel one 904 is assembled at the outer side position of the sprocket wheel two 907. A sprocket wheel two 907 is fixedly connected to the outer side of the rotating rod two 906. When the rotating rod one 902 rotates, it can drive the sprocket wheel one 904 fixedly connected to the rotating rod one 902 to rotate. Cooperating with the chain one 905 assembled on the outer side of the sprocket wheel one 904, the sprocket wheel two 907 driven by the chain one 905 and connected to the sprocket wheel one 904 through transmission rotates. Then the sprocket wheel two 907 drives the rotating rod two 906 fixedly connected to the sprocket wheel two 907 to rotate.

[0023] A turning plate 909 is rotatably connected to the side surface of the rotating rod two 906 through a torsion spring block 908. When the rotating rod two 906 rotates, and the turning plate 909 is assembled on the rotating rod two 906 through the torsion spring block 908, the rotating rod two 906 drives the turning plate 909 to rotate through the torsion spring block 908, so as to turn and stir the materials near the bottom position on the filter plate 300. Thereby, the contact area between the materials and the gas at this place is increased, and the use effect of the device is improved.

[0024] After the device is used up, the air pump 400 stops working, causing the wind wheel 903 to stop rotating, and then the rotating rod two 906 and the turning plate 909 stop working.

[0025] A turning component 700 for turning the materials is assembled inside the fermentation tank 100, and a dredging component 800 for dredging the liquid discharge port 600 is assembled inside the liquid discharge port 600.

[0026] During use, the materials are put into the fermentation tank 100 through the feeding port 200. At this time, the materials are on the filter plate 300. Start the air pump 400 to introduce the required gas into the fermentation tank 100. At this time, the fast-flowing gas drives the wind wheel 903 to rotate, causing the wind wheel 903 to drive the rotating rod one 902 fixedly connected to the wind wheel 903 to rotate. The rotating rod one 902 drives the sprocket wheel one 904 fixedly connected to the rotating rod one 902 to rotate. Cooperating with the chain one 905 assembled on the outer side of the sprocket wheel one 904, the sprocket wheel two 907 driven by the chain one 905 and connected to the sprocket wheel one 904 through transmission rotates. Then the sprocket wheel two 907 drives the rotating rod two 906 fixedly connected to the sprocket wheel two 907 to rotate. And the turning plate 909 is assembled on the rotating rod two 906 through the torsion spring block 908, so that the rotating rod two 906 drives the turning plate 909 to rotate through the torsion spring block 908, and turns and stirs the materials near the bottom position on the filter plate 300. Similarly, after the device is used up, the air pump 400 stops working, causing the wind wheel 903 to stop rotating, and then the rotating rod two 906 and the turning plate 909 stop working.

[0027] Example two, please refer toFigures 1 - 6 , on the basis of the first embodiment, the turning assembly 700 includes a first hydraulic chamber 701 that penetrates through the fermentation chamber 100 and is fixedly connected to the fermentation chamber 100. A cam 702 is fixedly connected to the top of the second rotating rod 906. A first stress rod 703 is slidably connected to the side of the first hydraulic chamber 701. When the second rotating rod 906 is in a rotating state, it can drive the cam 702 fixedly connected to the second rotating rod 906 to rotate. When the protruding part of the cam 702 rotates to the position of the first stress rod 703, it can squeeze the first stress rod 703.

[0028] A first spring 704 is assembled on the side of the first stress rod 703. A through second hydraulic chamber 705 is fixedly connected inside the second rotating rod 906. The second hydraulic chamber 705 is in a rotating connection state with the first hydraulic chamber 701 and is interconnected. When the first stress rod 703 is squeezed, the first stress rod 703 can compress the first spring 704 and slide into the first hydraulic chamber 701. Moreover, the first hydraulic chamber 701 is a chamber filled with oil inside. Thus, the oil in the first hydraulic chamber 701 is squeezed and moves to the side away from the first stress rod 703. Also, because the second hydraulic chamber 705 is connected to the first hydraulic chamber 701, and the second hydraulic chamber 705 is also a chamber filled with oil inside, part of the oil in the first hydraulic chamber 701 flows into the second hydraulic chamber 705.

[0029] An arc-shaped rod 706 is slidably connected to the side of the second hydraulic chamber 705. The arc-shaped rod 706 is located on the side of the turning plate 909 and is in a fixed state with the turning plate 909. When part of the oil in the first hydraulic chamber 701 flows into the second hydraulic chamber 705, the oil in the second hydraulic chamber 705 moves to the side away from the first hydraulic chamber 701. At this time, the oil in the second hydraulic chamber 705 can squeeze the arc-shaped rod 706 slidably connected to the second hydraulic chamber 705 and cause the arc-shaped rod 706 to move. The arc-shaped rod 706 can squeeze the turning plate 909 and drive the turning plate 909 to rotate by a certain angle.

[0030] When the protruding part of the cam 702 rotates away from the position of the first stress rod 703 as it rotates, the first stress rod 703 immediately loses its restriction and resets under the action of the first spring 704. Thus, the oil that originally flowed from the first hydraulic chamber 701 into the second hydraulic chamber 705 flows back into the first hydraulic chamber 701 again. Similarly, the oil that originally drove the arc-shaped rod 706 to move in the second hydraulic chamber 705 flows back and resets, causing the arc-shaped rod 706 to lose the extrusion of the oil. At this time, the arc-shaped rod 706 and the turning plate 909 can reset under the action of the torsion spring block 908. In this way, during the revolution of the turning plate 909 along with the second rotating rod 906, it can generate a reciprocating self-rotation by a certain angle. Further increasing the contact area between the material and the gas.

[0031] During use, on the basis of the first embodiment, when the second rotating rod 906 is in a rotating state, it can drive the cam 702 fixedly connected to the second rotating rod 906 to rotate. When the protruding part of the cam 702 rotates to the first stress rod 703, it can squeeze the first stress rod 703. At this time, the first stress rod 703 compresses the first spring 704 and slides into the first hydraulic chamber 701. Moreover, the first hydraulic chamber 701 is a chamber filled with oil inside, so that the oil in the first hydraulic chamber 701 is squeezed and moves to the side away from the first stress rod 703. Also, because the second hydraulic chamber 705 is connected to the first hydraulic chamber 701, and the second hydraulic chamber 705 is also a chamber filled with oil inside, part of the oil in the first hydraulic chamber 701 flows into the second hydraulic chamber 705, causing the oil in the second hydraulic chamber 705 to move to the side away from the first hydraulic chamber 701. At this time, the oil in the second hydraulic chamber 705 can squeeze the arc-shaped rod 706 slidably connected to the second hydraulic chamber 705 and cause the arc-shaped rod 706 to move. The arc-shaped rod 706 can then squeeze the turning plate 909 and drive the turning plate 909 to rotate at a certain angle. When the protruding part of the cam 702 rotates away from the first stress rod 703 as it rotates, the first stress rod 703 immediately loses its restraint and resets under the action of the first spring 704, so that the oil originally flowing into the second hydraulic chamber 705 in the first hydraulic chamber 701 flows back into the first hydraulic chamber 701. Similarly, the oil that originally drove the arc-shaped rod 706 to move in the second hydraulic chamber 705 flows back and resets, causing the arc-shaped rod 706 to lose the extrusion of the oil. At this time, the arc-shaped rod 706 and the turning plate 909 can reset under the action of the torsion spring block 908. In this way, the turning plate 909 can generate a certain angle of reciprocating self-rotation during the process of revolving with the second rotating rod 906.

[0032] Example three, please refer to Figures 1 - 8 , on the basis of the first and second embodiments, the dredging assembly 800 includes a third rotating rod 801 rotatably connected to the top of the fermentation tank 100. A first bevel gear 802 is fixedly connected to the top of the first rotating rod 902. A second bevel gear 803 is fixedly connected to one side of the third rotating rod 801. The second bevel gear 803 is located on the side of the first bevel gear 802 and is in a meshing state with the first bevel gear 802. When the first rotating rod 902 is in a rotating state, it can drive the first bevel gear 802 fixedly connected to the first rotating rod 902 to rotate. The first bevel gear 802 then drives the second bevel gear 803 meshing with it to rotate, so that the second bevel gear 803 drives the third rotating rod 801 fixedly connected to it to rotate.

[0033] On the other side of the third rotating rod 801, a third sprocket 804 is fixedly connected. A second chain 805 is assembled outside the third sprocket 804. A fixed seat 806 is assembled on the side of the fermentation tank 100. A penetrating reciprocating lead screw 807 is rotatably connected inside the fixed seat 806. A fourth sprocket 808 is fixedly connected to the side of the reciprocating lead screw 807. A sliding block 809 is assembled on the outside of the reciprocating lead screw 807 through threads. The sliding block 809 is located inside the fixed seat 806 and is in a sliding connection state with the fixed seat 806. A dredging rod 810 is fixedly connected to the side of the sliding block 809. When the third rotating rod 801 rotates, the third rotating rod 801 drives the third sprocket 804 fixedly connected to it to rotate. Cooperating with the second chain 805 assembled outside the third sprocket 804, the fourth sprocket 808 drivingly connected to the third sprocket 804 through the second chain 805 rotates. The fourth sprocket 808 then drives the reciprocating lead screw 807 fixedly connected to it to rotate. The sliding block 809 assembled on the outside of the reciprocating lead screw 807 through threads is restricted by the fixed seat 806 in sliding connection with it. Thus, the sliding block 809 reciprocates horizontally, driving the dredging rod 810 fixedly connected to the sliding block 809 to move. At this time, the dredging rod 810 reciprocates in the liquid discharge port 600. Preventing some materials from accidentally moving to the liquid discharge port 600 to block the liquid discharge port 600 improves the usability of the device.

[0034] During use, on the basis of Embodiment 1 and Embodiment 2, when the first rotating rod 902 is in a rotating state, it can drive the first bevel gear 802 fixedly connected to the first rotating rod 902 to rotate. The first bevel gear 802 then drives the second bevel gear 803 meshing with it to rotate, enabling the second bevel gear 803 to drive the third rotating rod 801 fixedly connected to it to rotate, causing the third rotating rod 801 to drive the third sprocket 804 fixedly connected to it to rotate. Cooperating with the second chain 805 assembled outside the third sprocket 804, the fourth sprocket 808 drivingly connected to the third sprocket 804 through the second chain 805 rotates. The fourth sprocket 808 then drives the reciprocating lead screw 807 fixedly connected to it to rotate. The sliding block 809 assembled on the outside of the reciprocating lead screw 807 through threads is restricted by the fixed seat 806 in sliding connection with it. Thus, the sliding block 809 reciprocates horizontally, driving the dredging rod 810 fixedly connected to the sliding block 809 to move. At this time, the dredging rod 810 reciprocates in the liquid discharge port 600.
