Description

Technical Field

[0001] The utility model relates to the technical field of feed production, in particular to a raw material screening device for crayfish feed production. Background Art

[0002] Crayfish feed is a special feed to meet the nutritional needs of crayfish growth and development. Crayfish feed includes animal protein, plant protein, carbohydrates, fat, vitamins and minerals, etc. When mixing the raw materials of crayfish feed, they need to be screened so that the raw materials of crayfish feed with different fineness can be processed and mixed separately.

[0003] For example, the Chinese patent "A discharging device for crayfish feed production" with announcement number CN217577358U includes a support frame, a discharge plate and a feed storage bucket. A fixed plate is installed in the middle of the inner side of the support frame, and a No. 1 fixed rod is installed inside the left side of the fixed plate. The discharge plate is installed at the front and rear ends of the No. 1 fixed rod, and a baffle is installed outside the discharge plate. The feed storage bucket is installed at the upper end of the inner side of the support frame, and a discharge plate is provided at the lower end of the feed storage bucket. A cylinder is provided at the lower end of the discharge plate. A support rod, and a weighing sensor is installed at the lower end of the cylinder support rod, a track is installed on the outside of the fixed plate, and the track is slidably connected to the fixed plate, a rotating rod is installed on the right side of the fixed plate, and the rotating rod is rotatably connected to the fixed plate, a No. 2 fixed rod is installed inside the rotating rod, and a rotating disk is installed on the front side of the rotating rod, a support plate is installed on the right side of the front part of the fixed plate, and a motor is installed on the upper end of the support plate, a rubber belt is installed inside the rear side of the motor, and the rubber belt is fixedly connected to the motor.

[0004] Although the above-mentioned prior art can realize the screening of crayfish feed, in actual use, on the one hand, it is difficult to subdivide feed of different coarseness and fineness in the feed, and the raw materials are directly processed and mixed during feed processing, resulting in feed of different particle sizes being mixed together, thereby reducing the purity of feed processing; on the other hand, it is difficult to adjust the inclination angle of the screening barrel when screening the feed, and the feed is directly poured into the screening machine during feed screening, resulting in excessive feed and easy accumulation, thereby reducing the screening accuracy, and therefore does not meet existing needs. In this regard, we propose a raw material screening device for crayfish feed production. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model can screen crayfish feed through the screening drum and the motor. When screening, the feed has been transported to the screening drum and tilted. At this time, the motor is turned on to make the output shaft of the motor drive the mounting rod to rotate together with the screening drum. The rotation of the screening drum causes the feed raw materials to tumble on it. During the tumbling process of the feed, the feed passes through the screening drum and falls to the lower end of the inside of the screening machine body. At the same time, three filter screens with different apertures are arranged on the screening drum, and the apertures of the filter screens increase successively, so as to subdivide feeds of different finenesses and avoid mixing of feed raw materials of different finenesses, thereby improving the purity of feed raw material processing.

[0017] 2. The utility model can adjust the inclination angle of the screening machine body through the hydraulic telescopic device and the support rod. When the feed is screened, the feed is poured from the funnel and then transported to the screening cylinder through the feed pipe. At this time, the hydraulic telescopic device is turned on to extend the telescopic end of the hydraulic telescopic device. The screening machine body on one side is pushed up by the telescopic end of the hydraulic telescopic device, thereby changing the inclination angle of the screening machine body. At the same time, the first connecting rod and the second connecting rod on both sides are rotated until the screening machine body is adjusted to a suitable angle. By increasing the angle, the lighter feed can move faster, and by reducing the angle, the heavier feed can be better distributed and rolled on the screening cylinder, thereby improving the screening effect.

[0018] 3. The utility model can timely recycle feed through the L-shaped fixing strip and the collecting box. When screening feed, feeds of different finenesses fall from different positions on the screening cylinder to the lower end of the screening machine body, and then fall into the collecting box from the discharge port. After a period of time, the collecting box is pulled outward to make the limiting strips at both ends of the collecting box slide on the L-shaped fixing strip until the collecting box is taken out of the L-shaped fixing strip, and then the limiting strips at both ends of the new collecting box are aligned with the opening between the L-shaped fixing strips and pushed into the L-shaped fixing strip until the collecting box moves to a suitable position, thereby simplifying the steps of feed recovery and thus accelerating the efficiency of the screening operation.

By increasing the angle, the lighter feed can move faster, and by reducing the angle, the heavier feed can be placed on the screening cylinder 17. For better distribution and tumbling, when the feed is screened, feeds of different finenesses fall from different positions on the screening cylinder 17 to the lower end of the screening machine body 2, and then fall into the collecting box 21 from the discharge port 18. After a period of time, the collecting box 21 is pulled outward to make the limiting strips 22 at both ends of the collecting box 21 slide on the L-shaped fixing strip 20 until the collecting box 21 is taken out from the L-shaped fixing strip 20, and then the limiting strips 22 at both ends of the new collecting box 21 are aligned with the opening between the L-shaped fixing strips 20 and pushed into the L-shaped fixing strip 20 until the collecting box 21 moves to a suitable position.
