Description

Technical Field

[0001] The utility model belongs to the technical field of fish scale grading and screening machines, and particularly relates to a fish scale grading and screening machine. Background Art

[0002] The fish scale grading and screening machine is a highly efficient screening device. Its name may come from the shape of its screen mesh, which resembles fish scales, or from its function in grading and screening fish scales in the fish processing industry (although more often it refers to the shape of the screen mesh). The working principle of the fish scale grading and screening machine is mainly based on vibration screening. The equipment uses a conventional motor or self-vibration source to drive the screen body to periodically reciprocate along the direction of the excitation force. The material on the screen surface has different screening parameters, thereby achieving the purposes of grading, dehydration, and de-mediation. The vibrating exciter drives the screen plate fixed to the vibrating screen box to vibrate in a specific vibration direction, throwing the material on the screen surface in the vibration direction. During the throwing process, material smaller than the sieve hole and passing through the sieve hole without resistance is separated through the sieve hole. The purpose of screening is achieved by the continuous separation process from the feed end to the discharge end.

[0003] When using the existing fish scale grading and screening machine, the screen of the fish scale screen is easily worn and damaged due to long-term contact with the material. Once the screen is damaged, it needs to be replaced. Since the screen is fixed and installed by screwing multiple bolts, the replacement process is relatively complicated and requires professional technicians to operate. This makes the replacement work more troublesome, which not only increases the maintenance cost of the equipment, but also may affect the normal operation and screening efficiency of the equipment. For this reason, we propose a fish scale grading and screening machine. Utility Model Content

[0021] In this embodiment, preferably, the connection limit assembly includes connection grooves 100 symmetrically opened at both ends of the vibration screening mechanism 2 and connection blocks 101 symmetrically fixed at both ends of the screen 4. The connection blocks 101 are engaged with the connection grooves 100 to facilitate the connection between the screen 4 and the vibration screening mechanism 2.

[0022] In this embodiment, preferably, the guide blocks 201 are symmetrically opened on both sides of the connecting block 101 in the guide groove 200 and symmetrically fixed on both sides of the inner wall of the connecting groove 100. The guide blocks 201 are slidably connected to the guide groove 200, so that the connecting block 101 can play a guiding role when it is inserted into the interior of the connecting groove 100.

[0023] In this embodiment, preferably, a card slot 300 and an elastic buckle 301 fixed inside the guide slot 200 are opened at the end of the guide block 201. The elastic buckle 301 is engaged with the card slot 300, so that the guide block 201 and the guide slot 200 can be limited together.

[0024] In this embodiment, preferably, the operating member includes an operating handle 400 symmetrically fixed on the surface of the screen 4 .

[0025] In this embodiment, preferably, the positioning and locking assembly includes positioning holes 500 symmetrically arranged on both sides of the screen 4 and screw holes 501 symmetrically arranged on both sides of the vibration screening mechanism 2.
