Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.
As shown in fig. 1-6, the internal inflow mesh plate grid comprises a frame 1, a mesh plate assembly 2, a mechanical transmission part 3 and a mesh plate transmission part 4, wherein the upper end of the mesh plate assembly 2 bypasses the mechanical transmission part 3, the mesh plate transmission part 4 drives the mechanical transmission part 3 to rotate, the mesh plate assembly 2 comprises a plurality of mesh plates 5 hinged end to end, a mounting groove 6 is arranged on each mesh plate 5, a tooth rake 7 is arranged in each mounting groove 6, each tooth rake 7 comprises a plurality of teeth 8 laid at intervals along the width direction of each mesh plate 5, a spring 9 is arranged between the side wall of each tooth rake 7 and the inner wall of each mounting groove 6, a gear 10 is arranged on the outer wall of each mounting groove 6 through a bearing seat, a shaft 11 is fixed on the side surface of each gear 10, a pull rope 12 is wound on each shaft 11, one end of each pull rope 12 is wound on each winding rope, and the other end of each pull rope 12, and a rack 13 meshed with the gear 10 is arranged on the frame 1. The rack 13 extends along the height direction of the rack 1, and the length of the rack 13 is slightly shorter than the height of the screen 5, so that the rake 7 takes out the sundries from the water in the rising process, then the rake rotates and descends, the gear 10 on the mounting groove 6 is meshed with the rack 13, the gear 10 rotates to drive the rotating shaft to rotate, the rotating shaft rotates to further wind the pulling rope 12 on the shaft 11, the pulling rope 12 pulls the rake 7 to be close to the gear 10, after the end part of the rake 7 contacts the side wall of the mounting groove 6, the pulling rope 12 continues to pull to reduce the distance between the teeth 8, and thus, the shearing is generated between the teeth 8, the sundries between the teeth 8 are removed, the cleanliness of the rake 7 is improved, the rake 7 takes out more sundries in the next round, and the removing efficiency is improved; a spring 9 is arranged between the end part of the toothed harrow 7 and the mounting groove 6, namely, the spring 9 is arranged between the tooth 8 at the side farthest away from the gear 10 and the mounting groove 6, the spring 9 is extended in the pulling process of the pull rope 12, and after the gear 10 is separated from the rack 13, the spring 9 is restored to the original state, so that the tooth 8 is pulled back to the original position, and further, the spring 9 can be arranged between the tooth 8 and the tooth 8 to ensure that the tooth 8 can be rebounded to the original position; the pulling rope 12 penetrates through the teeth 8 on one side close to the gear 10 and is fixedly connected with the teeth 8 which are farthest away from the gear 10, so that after the teeth 8 which are closest to the gear 10 are in place, the pulling rope 12 can continuously pull the rest teeth 8 to be close to the gear 10; the bottom of mounting groove 6 is equipped with the slide rail, and the bottom of tooth 8 is equipped with the pulley, and the pulley adaptation slide in the slide rail, and can not break away from the spout, and like this, the slip of the tooth 8 of being convenient for, simultaneously, also prevented that tooth 8 from breaking away from mounting groove 6.
