[0013] In summary, in the actual application process, after pouring cow dung into the fermentation box, cover the shielding cover. During the fermentation process, the adjusting motor can be started to drive the screw rod to rotate, so that the mounting plate moves left and right. At the same time, the linear motor can be started to move back and forth, so that the turning and raking rod can move horizontally and vertically, thereby turning and raking the cow dung. The intake pipe is connected to an external gas source to introduce air into the fermentation box, so that the cow dung is in full contact with the air for fermentation. The gas with an odor is introduced into the treatment box through the outlet pipe and passes through a plurality of activated carbon adsorption nets in sequence, thereby adsorbing the odor in the gas and greatly reducing the odor emitted by the air discharged from the treatment box, effectively avoiding the environmental pollution caused by the stench and the impact on the staff.

Specific embodiments

[0022] The following will make a detailed description of the two embodiments of the present application with reference to the accompanying drawings.

[0023] The first embodiment:

[0024] Figure 1 , Figure 2 , Figure 3 and Figure 4Shown: A fermentation bin for harmless treatment of cow dung, including a fermentation box 1. A shielding cover 2 is placed on the upper end of the fermentation box 1. The shielding cover 2 can cover the upper end of the fermentation box 1, effectively preventing the foul smell of cow dung from directly diffusing into the air. A positioning frame is fixedly connected to the lower end of the shielding cover 2. The outer wall of the positioning frame fits with the inner wall of the fermentation box 1, which can limit and fix the shielding cover 2, effectively preventing the shielding cover 2 from being displaced due to external bumps. A chute is drilled in the upper end of the shielding cover 2. An adjusting strip 3 is fixedly connected to the port of the chute. The left end of the adjusting strip 3 is fixedly connected to an adjusting motor 4. Those skilled in the art can select a suitable model of the adjusting motor 4 according to actual needs. For example: Y2-63M1-2-0.18KW. The output end of the adjusting motor 4 movably penetrates into the adjusting strip 3 and is fixedly connected to a screw rod 5. The right end of the screw rod 5 is rotatably connected to the right inner wall of the adjusting strip 3. A slider 6 is threadedly sleeved on the outer surface of the screw rod 5. Starting the adjusting motor 4 can drive the screw rod 5 to rotate, thereby causing the slider 6 to move, enabling the turning rod 10 to move horizontally. The lower end of the slider 6 movably penetrates through the chute and is fixedly connected to a U-shaped mounting plate 7. The surface of the slider 6 fits with the inner wall of the adjusting strip 3. The upper end of the mounting plate 7 fits with the lower end of the shielding cover 2. A slide rail 8 is fixedly connected inside the mounting plate 7. A linear motor 9 is slidably mounted on the outer surface of the slide rail 8. Those skilled in the art can select a suitable model of the linear motor 9 according to actual needs. For example: TJKK50. The lower end of the linear motor 9 is fixedly connected to a turning rod 10. Starting the linear motor 9 can drive the turning rod 10 to move back and forth, thereby turning the cow dung at different positions in the fermentation box 1. The turning rod 10 includes a support rod fixedly connected to the lower end of the linear motor 9. A circular plate is fixedly connected to the lower end of the support rod. A plurality of straight rods are fixedly connected to the lower end of the circular plate. The plurality of straight rods are arranged in a circular array around the central axis of the circular plate. The plurality of straight rods come into contact with the cow dung, which can effectively improve the turning efficiency. An air inlet pipe 17 is fixedly connected to the left end of the fermentation box 1. The air inlet pipe 17 is connected to an external air source, which can introduce air into the fermentation box 1, enabling the cow dung inside the fermentation box 1 to come into contact with the air, effectively improving the fermentation efficiency.

[0025] Figure 1 , Figure 2 and Figure 5It is shown that: a processing box 11 is provided on the right side of the fermentation box 1. A plurality of mounting frames 12 are provided at the front end of the processing box 11. A fixing frame 13 is provided inside the mounting frame 12. An activated carbon adsorption net 14 is fixedly connected inside the fixing frame 13. The activated carbon adsorption net 14 can adsorb and process the odor in the gas, thus effectively avoiding the influence of the stench on the surrounding environment. The rear end of the fixing frame 13 movably penetrates into the processing box 11. Two support bars 15 are provided at the lower end of the fixing frame 13. The two ends of the two support bars 15 away from each other are respectively fixedly connected to the left and right inner walls of the processing box 11. The support bars 15 can support and fix the fixing frame 13. An air outlet pipe 16 is fixedly connected between the fermentation box 1 and the processing box 11. The air containing odor in the fermentation box 1 enters the processing box 11 through the air outlet pipe 16. An exhaust pipe is fixedly connected to the upper end of the processing box 11. The gas is discharged from the processing box 11 through the exhaust pipe after being processed by the activated carbon adsorption net 14. Two insertion rods 18 are also fixedly connected to the rear end of the fixing frame 13. The rear ends of the insertion rods 18 movably penetrate the processing box 11. The insertion rods 18 can effectively improve the stability of the fixing frame 13 during use. A sealing rubber strip is also fixedly sleeved on the outer surface of the fixing frame 13. The sealing rubber strip is located inside the mounting frame 12. The sealing rubber strip can effectively prevent the odor from diffusing through the gap between the processing box 11 and the fixing frame 13, and at the same time makes the fixing frame 13 detachable and convenient for replacing the activated carbon adsorption net 14.

[0026] During use, after pouring cow dung into the interior of the fermentation box 1, cover the shielding cover 2. During the fermentation process, the adjusting motor 4 can be started to drive the screw rod 5 to rotate, drive the slider 6 to move, so that the mounting plate 7 moves left and right. At the same time, the linear motor 9 can be started to move back and forth, so that the turning and raking rod 10 can move horizontally and vertically, so as to turn and rake the cow dung. The air inlet pipe 17 is connected to an external air source to introduce air into the fermentation box 1, so that the cow dung is in full contact with the air for fermentation. The gas with odor is discharged into the interior of the processing box 11 through the air outlet pipe 16 and passes through a plurality of activated carbon adsorption nets 14 in sequence, so as to adsorb the odor in the gas, greatly reducing the odor emitted by the air discharged from the processing box 11, thus effectively avoiding the stench from polluting the environment and affecting the staff.

[0027] The second implementation mode:

[0028] On the basis of the first implementation mode, an axial flow fan 19 is newly added in this implementation mode, and the rest is the same as the first implementation mode.

[0029] Figure 6It is shown that an axial flow fan 19 is fixedly connected to the inner cavity of the exhaust pipe. Those skilled in the art can select an appropriate model of the axial flow fan 19 according to actual needs. For example: HTF. The regulating motor 4, the linear motor 9 and the axial flow fan 19 are all signal-connected to an external controller. Those skilled in the art can select an appropriate model of the controller according to actual needs. For example: OHR-B300A-A.

[0030] During use, the axial flow fan 19 can be started, thereby accelerating the air flow inside the treatment box 11 and the fermentation box 1, and thus effectively improving the odor treatment efficiency.

[0031] Combined with the current actual needs, the above-described implementation manner adopted in this application, the scope of protection is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of this utility model.
