At the same time, organic fertilizer can improve fertilizer utilization and reduce production costs. Fully and rationally using organic fertilizer can increase crop yield, improve soil fertility, improve agricultural product quality, and increase the effectiveness of soil nutrients. In the production process of organic fertilizer, fermentation is the most important step. Organic fertilizer needs to use fermentation to achieve the effects of heating, deodorization, killing pests, eggs, weed seeds, and increasing nutrients.

When existing equipment ferments organic fertilizer, there is a lack of waste gas treatment equipment. The organic fertilizer is discharged directly after fermentation. The gas generated during the fermentation process and the smell of the organic fertilizer itself are directly emitted into the air, which pollutes the environment very much.

[0022] In this embodiment, the organic fertilizer is placed in the crushing box 1, and the first motor 4 is started to drive one group of crushing rollers 2 to rotate. The first gear 3 connected to the other end is meshed with the third gear 7 through two groups of second gears 6. The third gear 7 is fixedly installed on one end of the other group of crushing rollers 2, thereby driving the two groups of crushing rollers 2 to rotate relative to each other. The organic fertilizer passes between the two groups of crushing rollers 2, and the protrusions 5 on the surface of the crushing rollers 2 roll against each other to crush the organic fertilizer, which is beneficial to the uniform mixing of the organic fertilizer after entering the fermentation cylinder 8, thereby providing a promoting effect for accelerating the fermentation speed.

When the barrel of the fermentation cylinder 8 rotates, the outer wall of the fermentation cylinder 8 fits against the surface of the support roller 22. The support roller 22 rotates with the rotation of the fermentation cylinder 8 due to the friction force, and can support the fermentation cylinder 8.

[0026] The extrusion assembly includes a first extrusion plate 11 and a second extrusion plate 16. The first extrusion plate 11 is slidably installed in the crushing box 1, and one side of the first extrusion plate 11 is connected to an extrusion rod 10; In this embodiment, the first squeezing plate 11 is moved closer to the second squeezing plate 16 to squeeze the organic fertilizer in the fermentation cylinder 8, so as to remove the moisture of the organic fertilizer as much as possible, increase the fermentation speed, greatly improve the fermentation efficiency, and effectively reduce the environmental pressure.

[0027] The waste gas treatment component includes a waste gas treatment box 30 and a spray component arranged in the waste gas treatment box 30. The waste gas treatment box 30 is connected to two groups of air bags 25. The air bags 25 are connected to the pressure valve 23 on the top of the crushing box 1. The extrusion rod 10 is fixedly connected to one side of the fixed plate 26 through the movable plate 27. The air bags 25 are connected to the waste gas treatment box 30 through the connecting pipe 36.

[0028] During the fermentation of organic fertilizer, a large amount of waste gas will be generated, which increases the internal pressure of the fermentation cylinder 8. After the pressure valve 23 detects the limit value, the valve opens to discharge the waste gas into the air bag 25, and no direct discharge will pollute the atmospheric environment. At the same time, the expansion of the air bag 25 is used to push the first extrusion plate 11 to complete the above-mentioned extrusion and dehydration process of the organic fertilizer.

[0029] The pressure valve 23 is fixedly connected to the outer wall of the fermentation cylinder 8, one end of the pressure valve 23 is connected to an exhaust pipe 24, the exhaust pipe 24 is connected to one end of the air bag 25, one end of the air bag 25 is fixedly connected to the top of the frame 19 through a fixed plate 26, a linear guide rail 29 is fixedly installed on one side of the support leg 20, a connecting plate 28 is installed on the guide block of the linear guide rail 29, and the connecting plate 28 and the movable plate 27 are fixedly connected.

[0030] In this embodiment, waste gas is filled into the airbag 25 to push the movable plate 27 to move toward the fermentation cylinder 8. The movable plate 27 is connected to the linear guide rail 29 via the connecting plate 28 to ensure the stability of the sliding structure of the extrusion rod 10 during the expansion of the airbag 25.

[0031] The exhaust gas treatment box 30 is connected to the airbag 25 through a connecting pipe 36. A filler plate 35 is arranged in the exhaust gas treatment box 30. The filler plate 35 is arranged at an angle, and adjacent filler plates 35 are connected end to end. A second spring 18 is fixedly connected in the guide sleeve 13. One end of the second spring 18 is connected to a guide rod 12. The guide rod 12 is slidably installed in the guide sleeve 13, and one end of the guide rod 12 is fixedly connected to the first extrusion plate 11.

[0032] After a certain period of exhaust gas discharge, when the air pressure in the fermentation cylinder 8 gradually decreases, the restoring force of the second spring 18 pushes the guide rod 12 out of the guide sleeve 13, driving the first extrusion plate 11 to move toward the side of the exhaust gas treatment box 30, and the extrusion rod 10 drives the moving plate 27 to move to compress the airbag 25. Since the airbag 25 is connected to the exhaust gas treatment box 30 through the connecting pipe 36, the exhaust gas can be discharged into the exhaust gas treatment box 30 for purification.

[0033] It should be noted that an obliquely cut filler plate 35 is provided in the waste gas treatment box 30. The filler plate 35 is configured to fill an activated carbon layer between the filter plates, thereby improving the efficiency of purifying the waste gas.

[0036] In this embodiment, a DMF solvent aqueous solution with a concentration of 14.5%-18.5% is poured into the water tank 31. While the airbag 25 is inflated, the piston rod 33 is moved in the pressurizing cylinder 32 to draw the 14.5%-18.5% DMF solvent aqueous solution into the pressurizing cylinder 32. When the exhaust gas is discharged from the airbag 25, the piston rod 33 moves in the opposite direction to squeeze the 14.5%-18.5% DMF solvent aqueous solution into the first spray pipe 38, and then sprayed into the exhaust gas treatment box 30 through the spray nozzle 39.

[0037] In the present invention, organic fertilizer is put into a crushing box 1 for crushing pretreatment, and the crushed organic fertilizer falls into a fermentation cylinder 8, and a first motor 4 is started to drive one group of crushing rollers 2 to rotate, and a first gear 3 connected to the other end thereof is meshed with a third gear 7 through two groups of second gears 6, and the third gear 7 is fixedly installed on one end of another group of crushing rollers 2, thereby driving the two groups of crushing rollers 2 to rotate relative to each other, and the organic fertilizer passes between the two groups of crushing rollers 2, and the protrusions 5 on the surface of the crushing rollers 2 are used to crush the organic fertilizer, thereby improving the subsequent fermentation and mixing effect; The second motor 9 is started to drive the fermentation cylinder 8 to rotate around the external rotating shaft connected to the second motor 9. The material-moving rod 15 is fixed in the fermentation cylinder 8 to mix the organic fertilizer in coordination with the rotation of the fermentation cylinder 8 to prevent the organic fertilizer from accumulating and fermenting insufficiently. During the fermentation of organic fertilizer, a large amount of waste gas is generated, which increases the internal pressure of the fermentation cylinder 8. After the pressure valve 23 detects the limit value, the valve is opened to discharge the waste gas into the airbag 25. The airbag 25 expands after being filled with waste gas, and the first extrusion plate 11 can be pushed close to the second extrusion plate 16. The two squeeze the organic fertilizer in the fermentation cylinder 8 to discharge the moisture in the fermentation cylinder 8, thereby increasing the fermentation speed, greatly improving the fermentation efficiency, and effectively reducing the environmental pressure. After a certain period of exhaust gas discharge, the air pressure in the fermentation cylinder 8 gradually decreases, and the guide rod 12 is pushed out of the guide sleeve 13 by the reset force of the second spring 18, driving the first extrusion plate 11 to move toward the exhaust gas treatment box 30. The extrusion rod 10 drives the moving plate 27 to move to compress the airbag 25, and the exhaust gas is discharged into the exhaust gas treatment box 30. The exhaust gas is filtered and purified by the filler plate 35 layer by layer before being discharged; While the airbag 25 is inflated, the piston rod 33 is moved in the pressurizing cylinder 32 to draw a 14.5%-18.5% DMF solvent aqueous solution into the pressurizing cylinder 32. When the waste gas is discharged from the airbag 25, the piston rod 33 moves in the opposite direction to squeeze the 14.5%-18.5% DMF solvent aqueous solution into the first spray pipe 38, and then sprayed into the waste gas treatment box 30 through the spray nozzle 39 for further purification, which effectively avoids pollution to the environment and will not cause harm to the operator.

During the inflation process, the airbag 25 pushes the first extrusion plate 11 to squeeze the organic fertilizer in the fermentation cylinder 8 to discharge the moisture in the fermentation cylinder 8; Step 3: After the waste gas is discharged, the air pressure in the fermentation cylinder 8 decreases, the second spring 18 is reset to push out the movable plate 27, squeeze the air bag 25, and squeeze the waste gas into the waste gas treatment box 30 for purification; Step 4: While step 2 is being implemented, the pressurizing cylinder 32 draws in the aqueous solution through the pumping pipe 34 .
