Each pig pen 601 is provided with a feed guide trough 1. The bottom of the feed guide trough 1 is the guide pipe 101. When the compartment is flushed, the wastewater is collected through the feed guide trough 1 and flows into the guide pipe 101 for transportation. The interior of the separation box 2 is obliquely provided with a grid net 201, the bottom end of the diversion pipe 101 is connected to the top of the separation box 2, and the bottom end of the diversion pipe 101 is located directly above the grid net 201. The wastewater transported by the diversion pipe 101 is separated from the wastewater and feces at the grid net 201, so that the solid feces are retained on the grid net 201, and slide along the grid net 201 into the lifting hopper 7 in the collection bucket 3, which can concentrate the wastewater from multiple pig pens 601 in the pig farm pens 6, and separate the feces in the process of concentrating the wastewater. The collection bucket 3 is arranged on one side of the separation box 2 and connected to the bottom of the grid net 201, and is used to collect the separated feces. The sedimentation box 4 is arranged at the bottom of the grid net 201, and the wastewater is settled and post-processed through the sedimentation box 4. The outlet of the sedimentation box 4 can be connected to the subsequent processing unit to purify and recycle the wastewater. The lifting hopper 7 is installed on the inner side of the collecting hopper 3 and is used for lifting the collected feces.

[0037] In this embodiment, the lifting hopper 7 includes a hydraulic push rod 71, a hopper body 72, a connecting rod 73 and a top cover 74. One end of the hopper body 72 is provided with a discharge port 701. Several connecting rods 73 are arranged on the top of the hopper body 72, and the top ends of several connecting rods 73 are connected to the top cover 74. The telescopic end of the hydraulic push rod 71 is connected to the top cover 74, and the hydraulic push rod 71 is installed on the outside of the enclosure 6. There are four connecting rods 73. The hopper body 72, the connecting rod 73 and the top cover 74 are lifted and lowered as a whole through the extension and retraction of the hydraulic push rod 71. The hopper body 72 is inserted into the inner side of the collecting hopper 3 and can be lifted and lowered along the collecting hopper 3. After the feces are separated, they slide into the hopper body 72 along the grid 201. After the hopper body 72, the connecting rod 73 and the top cover 74 are lifted as a whole, the feces can be lifted out of the collecting hopper 3 to the ground.

[0038] When the bucket body 72 descends into the collecting bucket 3, the top cover 74 is closed to the ground.

[0039] It can be understood that the collecting bucket 3 is buried under the ground, and when the feces are lifted out of the collecting bucket 3 to the ground, it is convenient to clean out the feces later.

[0040] In this embodiment, in order to clean and push out the feces at one time, the transverse push plate 8 includes a linear drive member 81 and a push plate 82. The linear drive member 81 is installed on the inner top wall of the top cover 74, and the push plate 82 is connected to the movable end of the linear drive member 81. The linear drive member 81 drives the push plate 82 to move to clean out the feces, and the feces is pushed and scraped out from the discharge port 701.

[0041] It can be understood that the ground is provided with a sunken road surface at the discharge port 701, so that the transport vehicle can move to the discharge port 701, and the truck bucket that can hold feces is placed under the discharge port 701. During the cleaning of feces, the feces can be received for subsequent transfer to fertilizer production.

[0042] Specifically, the linear drive member 81 includes a driving motor 811, a wire lever 812 and a guide rod 813.

Under the drive of the driving motor 811, the wire lever 812 is driven to rotate. Under the sliding limit of the guide rod 813, the push plate 82 is guided to fit the inner wall of the bucket body 72 and slide along its length direction, thereby pushing the feces accumulated in the bucket body 72 toward the discharge port 701.

[0043] It is understandable that the linear drive member 81 may be any other device having a linear drive function, such as a lead screw guide pair driven by a stepping motor.

[0044] In one embodiment, a partition 401 is provided on the inner top wall of the sedimentation tank 4, and the partition 401 is located on the side away from the grid 201. After the wastewater is filtered through the grid 201, it enters the sedimentation tank 4 from the left side of the partition 401 and is discharged from the right side of the partition 401.

[0045] Furthermore, an overflow pipe 402 is provided on a side of the sedimentation box 4 away from the grid 201. After sedimentation, the wastewater overflows through the overflow pipe 402 and is discharged to a subsequent treatment unit.

[0046] In one embodiment, the sedimentation box 4 is further provided with a suction assembly 5 for sucking the flocculants settled to the bottom. The internal feces particles are sucked by the suction assembly 5 and can be used as wet feces fertilizer.

[0047] Furthermore, the suction assembly 5 includes a pump body 51, a first tube 52 and a second tube 53. The first tube 52 and the second tube 53 are respectively arranged at both ends of the pump body 51. The first tube 52 passes through the sedimentation tank 4 and is inserted into the interior of the sedimentation tank 4. By starting the pump body 51, the sediment in the sedimentation tank 4 is extracted through the first tube 52 and discharged through the second tube 53.

[0048] In a certain embodiment, in order to utilize gravity to automatically guide wastewater downward when collecting it, the inner bottom wall of the guide trough 1 is an inclined surface, and the top end of the guide pipe 101 is located at the bottom end of the inclined surface, and the guide pipe 101 is inclined downward, so that in the guide trough 1, the wastewater flows downward along the inclined surface, and then flows into the separation box 2 in the guide pipe 101 for treatment.

[0049] The specific working process of the utility model is as follows: the pig pen 601 in the pen 6 is flushed to generate wastewater mixed with feces, the wastewater flows into the guide trough 1, flows downward from the inclined surface of the guide trough 1 to the guide pipe 101, and then flows downward from the guide pipe 101 to the separation box 2, and falls to the grid 201, the feces and wastewater are separated in the grid 201, the wastewater is settled in the sedimentation box 4, and the feces retained on the grid 201 slides into the collecting bucket 3 and accumulates in the bucket body 72, the bucket body 72, the connecting rod 73 and the top cover 74 are lifted as a whole by the contraction of the hydraulic push rod 71, and lifted above the ground, and then the push plate 82 is driven by the linear drive member 81 to push and clear in the bucket body 72, and the feces are pushed out of the bucket body 72 to the discharge port 701, and the feces are cleared out at one time for the transport vehicle to load and transfer.

[0050] The entire workflow is completed, and the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
