Description
Round vibrating screen convenient for replacing screen plate Technical Field The utility model relates to the technical field of vibrating screens, in particular to a circular vibrating screen with a screen plate convenient to replace. Background The multilayer linear vibrating screen utilizes the vibration motor excitation principle to enable materials to be thrown up on a screen surface, and meanwhile, the screen reasonably matched with the screen surface is moved forwards in a linear manner, so that the screening purpose is achieved, the vibration is stable, the noise is extremely low, the operation is simple, the screening performance is excellent, the materials continuously vibrate on the screen in the screening process, the materials are continuously contacted and rubbed with the screen, the screen is easy to damage, and if the damaged screen is not replaced in time, the screened materials are uneven in thickness. The prior art has the following problems: Through finding after a large number of retrieval, the patent document of application number CN201920855189.0 discloses a round vibrating screen convenient to change screen cloth, and this patent is through rotating set screw then taking off set screw, alone downwardly pulling bottom plate, and the bottom plate drives the connecting rod and slides down, and the connecting rod drives the roof and slides down and get into in the spout, then through pulling the screen cloth, and the screen cloth is under the rotation of runner, guarantees that the screen cloth can not block in the reel, guarantees the normal slip of screen cloth, guarantees the normal dismantlement installation of screen cloth. According to the above patent, the problem that still exists needs in the in-service use of current patent is found to the above-mentioned patent, and it is comparatively obvious to need dismantle a plurality of set screws, and easily lead to skew or jamming because of the atress is uneven when the sieve slides, and change the process and need many people to cooperate, and there is no guide structure between sieve and the reel, need adjust the position repeatedly during the installation, easily causes the wearing and tearing at sieve edge. For this reason, we propose a circular vibrating screen which is convenient for replacing the screen plate to solve the above-mentioned disadvantages. Disclosure of utility model The utility model aims to solve the defects in the prior art and provides a circular vibrating screen which is convenient for replacing a screen plate. In order to achieve the purpose, the circular vibrating screen convenient for replacing the screen plate comprises a support frame and the screen plate, wherein one ends, close to each other, of the support frame and the screen plate are of an inverted trapezoid structure, a first cavity is formed in the support frame, a lock tongue is arranged in the first cavity through a spring, a second cavity is formed in one side of the first cavity and is communicated with the first cavity through a sliding groove, a sliding block is connected inside the sliding groove in a sliding mode, one end of the sliding block is fixedly connected with the lock tongue, a rack is arranged in the second cavity, a gear is meshed on the rack, a hand wheel is arranged on the outer wall of the support frame, one end of the hand wheel is fixedly connected with the gear, a lock hole is formed in the surface of the screen plate, and the lock tongue is matched with the lock hole. Preferably, the pulley is installed to the inner wall of support frame, and the pulley is equipped with a plurality of. Preferably, one end of the lock tongue, which is close to the sieve plate, is of a wedge-shaped structure. Preferably, the edge of the sieve plate is wrapped with a sealing strip. Preferably, the length of the first chamber is greater than the total length of the spring and the tongue. Preferably, the length of the sliding block is greater than the depth of the sliding groove. Compared with the prior art, the utility model has the beneficial effects that: According to the utility model, the inverted trapezoid structure is arranged on the sieve plate and the support frame, so that the guide function is realized, the rapid positioning can be assisted, the pushing between the sieve plate and the support frame, namely the positioning, is realized, the freehand operation of the spring bolt is combined, no additional tool is needed, and the sieve plate is convenient and labor-saving to replace. According to the utility model, the plurality of pulleys are arranged, so that the friction force between the sieve plate and the supporting frame in the installation process can be greatly reduced, and the guide is smoother and more labor-saving. Drawings In order to more clearly illustrate the embodiments of the present utility model or the technical solutions in the prior art, the drawings that are needed in the embodiments will be briefly described bel
