[0015] In order to make the utility model purposes, technical scheme and advantages more clearly, following combining with the drawing and example, the utility model is further detailedly explained.It should be understood that the specific example described here is only used to explain the utility model, and is not used to limit the utility model.

[0016] As Figure 1 And Figure 2 The utility model discloses a biological filter for rural domestic sewage treatment, which comprises a pool body 1, a filter plate 2 in L shape in the pool body, and the filter plate 2 is in sliding fit with the pool body 1, the filter plate 2 is evenly provided with filter holes 21, one side of the top of the pool body 1 is provided with a connection seat 3, and the connection seat 3 is in sliding connection with the pool body 1, the front end of the connection seat 3 extends into the upper part of the pool body 1, and the front end of the connection seat 3 is provided with an opening slot 31, the longitudinal plate of the filter plate 2 is slidably arranged on the opening slot 31, a gear 32 is arranged in the opening slot 31, the gear 32 is driven to rotate by a first motor 33, the longitudinal plate of the filter plate 2 is provided with a gear slot 22 engaged with the gear 32, a second motor 4 is arranged on the pool body 1, the second motor 4 is connected with a screw rod 41, the screw rod 41 is provided with a screw nut 42 matched therewith, and the screw nut 42 is connected and fixed with the connection seat 3.

[0017] As a preferred embodiment, the pool body 1 is in the shape of a cuboid.

[0018] As a preferred embodiment, the filter plate 2 is matched with the shape of the pool body 1.

[0019] The utility model discloses a biological filter for rural domestic sewage treatment, through control mechanism, the transverse and longitudinal movement of the filter plate 2 is driven, so that the filter plate 2 salvages and cleans the sundries suspended in the pool body 1.

[0020] Specifically, in use, the second motor 4 can drive the screw rod mechanism to work, so that the connection seat 3 is driven to move transversely, and then the filter plate 2 is driven to move transversely in the pool body 1, and then the suspended sundries in the pool body 1 are accumulated to one side of the pool body 1.

[0021] At this time, the rotation of the gear 32 is driven by the first motor 33, so that the gear 32 is engaged with the gear slot 22 to drive, thereby controlling the rising of the filter plate 2, so that the sundries accumulated thereon are left on the horizontal plate of the filter plate 2, and are fished out above the sewage of the pool body 1 to be collected and treated.

[0022] The above-described embodiments are merely preferred embodiments of the present application, and are not intended to limit the concept and scope of the present application. Various modifications and improvements to the technical solutions of the present application made by those of ordinary skill in the art without departing from the design concept of the present application shall fall within the protection scope of the present application, and the technical content of the present application claimed for protection has been fully recorded in the claims.
