Description

A self-cleaning differential speed double-roll crusher for shrimp feed production

technical field

The utility model relates to the technical field of crushers, in particular to a self-cleaning differential speed double-roller crusher for shrimp material production.

Background technique

In the production of aquatic feed, crushers are often used to crush pellet feeds of 1.8mm to 2.2mm into small, medium and large feeds. The particle sizes of different crushing degrees are 0.25 to 0.35mm, 0.35 to 0.55mm, 0.55～0.9mm. During the production and crushing process of medium crushing and small crushing feed, large crushing has to be produced at the same time or needs to be broken back. During the feed crushing process of the existing crusher, part of the feed will stick to the crushing roller, which is difficult to clean and accumulate. Multiple layers will affect the shattering effect.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

As shown in Figures 1 and 2, a self-cleaning differential double-roller crusher for shrimp feed production includes a crushing box 1, the top surface of the crushing box 1 is provided with a feed hopper 2, and the inside of the crushing box 1 is parallel. A drawing roller A3 and a drawing roller B4 are provided, and several crushing gears A5 and crushing gears B6 are arranged at intervals between the drawing roller A3 and the drawing roller B4. The gear A5 corresponds to the crushing gear B6 on the drawing roller B4, the crushing gear B6 on the drawing roller A3 corresponds to the crushing gear A5 on the drawing roller B4, and the rotation shafts of the drawing roller A3 and the drawing roller B4 pass through the crushing box 1 The front and rear side walls of the crushing box 1 are provided with a transmission gear A7 and a transmission gear B8 at the ends of the two rotating shafts close to the rear side wall of the crushing box 1. The diameter of the transmission gear A7 is different from that of the transmission gear B8. The transmission gear A7 and the transmission gear B8 mesh with each other, and the outer front side wall of the crushing box 1 is fixed with a drive motor 9, and the output end of the drive motor 9 is fixedly connected with a rotating shaft, and is located between the wire drawing roller A3 and the wire drawing roller. The top of the crushing box 1 above the roller B4 is obliquely provided with several air nozzles 10, the airflow direction in the air nozzle 10 above the drawing roller A3 is aligned with the drawing roller A3, and the airflow direction in the air nozzle 10 above the drawing roller B4 is aligned with the wire drawing Roller B4, the outer top surface of the crushing box 1 is also provided with an air pump 11, the air pump 11 is fixedly connected with the air nozzle 10 through the air pipe, the bottom surface of the crushing box 1 is provided with a discharge hopper 12, and the inside of the discharge hopper 12 is inclined. There is a screen 14, the screen 14 is fixedly connected to the inner side wall of the discharge hopper 12, the discharge hopper 12 at the lowest point of the screen 14 is provided with a material pipe, and the outer wall of the discharge hopper 12 below the material pipe is movable to be provided with a collection box 13. A vibrating motor 15 is fixed at the discharge hopper 12 located at the top of the screen 14, and the vibration motor 15 is in contact with the screen 14.
