Flexible actuating mechanism 23 contains the drive plate, the drive plate sets up and serves at the displacement of displacement mechanism 12, just drive plate 23 contains the equidistance displacement section 31 and the drive displacement section 32 of following supreme setting down, equidistance displacement section 31, drive displacement section 32 are vertical plane towards the one side in the telescopic link, the drive displacement section is compared in the setting of equidistance displacement section towards the telescopic link protrusion, equidistance displacement section and drive displacement section smooth transition set up, the cover is equipped with reset spring 29 on the telescopic link 22, just the telescopic link passes through reset spring to be connected in the gas injection barrel, reset spring 29 is located between sealed end plate 28 and the gas injection piston 21.

As shown in fig. 3 and fig. 6, a vibration exciter 41 is disposed at the bottom of the water penetration filter plate 4, the water penetration filter plate 4 is arranged in a vertical direction in a vibrating manner, a scraper 42 is arranged at the upper gap of the water seepage filter plate 4, the scraper 42 is fixedly arranged on the rotary rotating shaft of the lifting mechanism 2, an elastic pad 43 is arranged between the scraper 42 and the rotary rotating shaft, so as to adapt to and compensate the displacement deviation of the water seepage filter plate 4 generated during the oscillation, the outer edge of the water seepage filter plate 4 is connected with the top end of the suction cylinder body 10 through a corrugated pipe so as to adapt to and compensate the displacement deviation of the water seepage filter plate 4 generated during the oscillation, the water permeability of the water seepage filter plate can be improved through the vibration of the water seepage filter plate, the scraper 42 can prevent the water seepage filter plate from being blocked to a certain degree, and the fertilizer above the water seepage filter plate can be turned over, so that the adhesion is reduced, and meanwhile, the downward flow of the water solution is facilitated.

A preparation process of an organic bio-fertilizer pretreatment fermentation preparation system comprises the following steps:

s1: organic fertilizers such as animal wastes, plant residual leaves and the like are placed in an inner cavity of a fermentation container 1, microbial additives such as aerobic bacteria and the like are added, the organic fertilizers are crushed and stirred by a crushing mechanism 7, a generated aqueous solution seeps into a liquid collecting container 5 through a water seepage filter plate 4, the crushed fertilizers enter a fertilizer lifting channel 6 and are lifted upwards by a lifting mechanism 2, the fertilizers lifted to the top end of a lifting barrel 3 are contacted with air and then fall back into the fermentation container 1, and the organic fertilizers in the fermentation container are lifted and fall back in a circulating manner;

s2: part of the generated water solution is accumulated on the water seepage filter plate 4, and the water solution in the fermentation container is periodically or periodically sucked by a filtrate sucking mechanism, so that the water solution is discharged into a water collecting container 5 through the water seepage filter plate;

s3: when the drawing piston 11 is displaced to the lower part of the overflow port 14, the solution in the drawing cavity 17 flows into the liquid collection cavity 18 through the overflow port;

s4: when the drawing piston 11 is in a downward displacement state, the gas injection piston 21 blocks the gas injection outlet 201, the drawing cavity 17 generates negative pressure, and the water solution in the fermentation container 1 flows into the drawing cavity through the water seepage filter plate 4;

when the drawing piston 11 is in an upward displacement state, the gas injection piston 21 is spaced from the gas injection outlet 201, the gas injection outlet is communicated with the gas injection inlet, the drawing cavity 17 is filled with air and high pressure is generated in the drawing cavity 17, the drawing piston 11 pushes the gas to enter the fermentation container through the water seepage filter plate 4, and simultaneously, the filter holes of the water seepage filter plate 4 are backwashed, and organic matters in the fermentation container are oxygenated.

The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
