[0040] As shown in Figure 4 , Figure 10 , Figure 11 and Figure 14 , pulley 7 is arranged on push plate 3, and the number of pulley 7 is consistent with the number of guide 142, that is, consistent with the number of sliding groove 140. Specifically, push plate 3 comprises plate body 31, first mounting seat 32 and second mounting seat 33. First mounting seat 32 is mounted on plate body 31, and is located on the side of plate body 31 close to combined rack 1. First mounting seat 32 is provided with two, and is distributed on both ends of plate body 31. First mounting seat 32 is used for mounting pulley 7, and two pulleys 7 are arranged on each first mounting seat 32.

Reinforcing plate 331 is perpendicular to vertical plate 332, and the height of reinforcing plate 331 is lower than the height of the through hole, so as to ensure that reinforcing plate 331 does not affect the through hole, thereby facilitating installation of bolts.

[0041] As Figure 12 and Figure 13 The push rod 4 includes a rod body 41 and a rod cap 42, which is detachably mounted on the rod body 41. Specifically, the rod cap 42 is provided with an internal thread, and the push rod 4 is provided with a threaded column, and the rod cap 42 is screwed on the threaded column. The rod cap 42 is made of wear-resistant and corrosion-resistant material to prolong the service life of the rod cap 42. The outer wall of the rod cap 42 is provided with tightening planes 4221, which are six, and the six tightening planes 4221 are connected in turn and wrap around the rod cap 42, that is, the tightening planes 4221 are uniformly distributed along the axis of the rod cap 42, so that the rod cap 42 can be tightened on the rod body 41 by using a wrench or the like. The rod cap 42 also has a guide surface 4231, which is inclined. Specifically, the front end of the rod cap 42 is a small-diameter section 421, which has a diameter smaller than that of the filter hole 51 and can be easily inserted into the filter hole 51. The rear end of the rod cap 42 is a large-diameter section 422, which has the same diameter as the filter hole 51. The middle section of the rod cap 42 is a transition section 423, which connects the small-diameter section 421 and the large-diameter section 422. The transition section 423 is tapered, and the outer wall of the transition section 423 serves as the guide surface 4231. The diameter of the large-diameter section 422 is the same as that of the rod body 41. In this way, when the rod body 41 deviates from the filter grate 5, the rod body 41 can be guided to be inserted into the filter hole without directly colliding with the filter grate 5 to cause the push rod 4 to bend and fail.

[0042] The rod body 41 is made of wear-resistant material and can be bent and deformed, and can automatically recover after the external force disappears. For example, it is made of PA66 nylon material, which has excellent wear resistance and strong chemical corrosion resistance, excellent applicability in sewage environment, and bending strength of about 100-110 MPa. After bending, it can recover and deform to ensure that the rod body 41 is always centered with the filter hole 51 on the filter grate 5. The rear end of the rod body 41 is inserted into the push plate 3 and fixed by a nut. The rear end of the rod body 41 is provided with a force-bearing step 411, which can increase the contact area with the push plate 3 and improve the ability of the rod body 41 to bear the thrust. The rear end of the rod body 41 has a tightening section 413, which is hexagonal in shape, that is, the tightening section 413 has the same structure as the tightening planes 4221 of the rod cap 42, facilitating the disassembly and assembly of the push rod 4. The force-bearing step 411 is provided with a sealing groove 412, and a sealing ring (not shown) is arranged in the sealing groove 412 to form a seal between the push plate 3 and the push rod 4, effectively preventing the penetration of sewage into the back of the push plate 3 and the end tightening nut of the push rod 4.

[0043] When the filter holes 51 of the filter screen 5 are blocked, the driver 2 drives the push plate 3 to move, the push plate 3 drives the push rod 4 to move, the push rod 4 is inserted into the filter holes 51 of the filter screen 5 under the guidance of the rod cap 42, thereby dredging the filter holes 51, and the mechanical equipment is used to replace the manual work, and the efficiency is improved. Meanwhile, detachable connection is adopted between the components, the components can be flexibly disassembled, and the components are convenient to carry and install; the structure of the slide rail and the push plate 3 guarantees that the push rod 4 moves along the predetermined track, the push rod 4 can be accurately aligned with the filter holes 51; the hydraulic system is used to provide power, and the unsafe factors such as electric leakage of the electric power can be avoided.

[0044] The above is only the embodiment of the utility model, and does not limit the patent range of the utility model, and equivalent structures using the contents of the utility model specification and drawings, direct or indirect application in other related technical fields, are also within the patent protection range of the utility model.
