Embodiment
Below in conjunction with accompanying drawing, explanation is explained in detail to structure of the present utility model.
A kind of organic fertilizer fermentation tank as shown in Figure 1, comprises tank body 5 that is tubular, that close, tank body 5 has opening for feed 2 and discharge port 6.Opening for feed 2 is for fill material, and discharge port 6 is for flowing out the organic fertilizer raw material of the generation after fermentation.
The utility model and conventional fermentor tank unlike: be provided with the support roller 10 that at least one pair of supports tank body 5 bottom the tank body 5 of fermentor tank of the present utility model, this support roller 10 comprises the one group of wheel supporting tank body 5, and can rotate with the rotation of tank body 5, each support roller 10 is other is respectively equipped with gear wheel, the protruding side that gear wheel and tank body 5 stretch out offsets, for avoiding tank body 5 axially to move, there is position-limiting action.Tank body 5 outer radial is surrounded with the driving cog 1 affixed with tank body 5; Also comprise the motor 8 for providing propulsion source, motor 8 output shaft is connected with power wheel 7, and power wheel 7 is connected with driving cog 1 gear, and along with the rotation of motor shaft, fermentor tank rotates thereupon; Tank body 5 internal welding is connected to central shaft 9, central shaft 9 is welded with paddle 3, and under the acting in conjunction of fermentor tank and inner paddle 3 thereof, the material in fermentor tank and oxygen obtain sufficient contact, decrease fermentation time, improve fermentation efficiency.
