Description

Technical Field

[0001] The utility model relates to the field of feed production, in particular to a duck feed anti-sticking wall uniform mixing device. Background Art

[0002] Duck feed needs to be mixed with a variety of raw materials during the production process, including corn, wheat, bran, broken rice, fish meal, bone meal, shell powder, salt, etc. In the prior art, stirring and mixing are mostly used. In order to improve the uniformity of stirring, multiple groups of stirring rods are usually set up for stirring together. For example, a feed mixer disclosed in application number 202322560552.5 greatly improves the stirring efficiency by arranging stirring rods on the wall of the mixing drum and stirring together with the stirring rods in the barrel. However, the centrifugal force generated by the rotation of the material will cause the material to accumulate in the area close to the outside of the barrel cavity and form a compaction, so that this part of the material cannot be fully stirred; at the same time, due to the increased resistance of the stirring rods on the barrel wall and the inner wall of the barrel itself to the material, the material will be more easily retained on the barrel wall, and the residual material on the barrel wall needs to be cleaned up later, affecting the feed production efficiency.

[0005] The scraper is an isosceles triangular plate with a vertically placed bottom edge. The horizontal length of the scraper is greater than the straight-line distance from the end of the first stirring rod to the inner wall of the cylinder. In the absence of external force, the bottom edge of the scraper is always in contact with the inner wall of the cylinder, and the two waist sides of the scraper are sharpened.

[0016] The specific implementation of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0017] Depend on Figures 1 to 3 The utility model includes a cylinder body 1, which is a cylindrical shell opened at the top and the bottom. A stirring shaft 2 which rotates alternately forward and reversely is coaxially arranged in the middle of the cylinder body 1. A plurality of first stirring rods 3 are evenly fixed along the circumference of the stirring shaft 2. The first stirring rods 3 are provided with multiple layers up and down. A plurality of second stirring rods 4 are evenly fixed along the circumference on the cylinder wall of the cylinder body 1. The second stirring rods 4 are provided with multiple layers up and down and are arranged alternately with the first stirring rods 3 from top to bottom. A vertically placed scraper 5 is hinged to the outer end of each first stirring rod 3. The scraper 5 can swing horizontally around the hinge axis. When the outer end of the scraper 5 contacts the inner wall of the cylinder body 1, all the scrapers 5 are horizontally inclined at the same angle to the first stirring rod 3.

[0018] The scraper 5 is an isosceles triangular plate with a vertically placed bottom edge. The horizontal length of the scraper 5 is greater than the straight-line distance from the end of the first stirring rod 3 to the inner wall of the cylinder 1. In the absence of external force, the bottom edge of the scraper 5 is always in contact with the inner wall of the cylinder 1, and the two waist sides of the scraper 5 are sharpened.

[0019] A torsion spring is provided at the hinged position between the scraper 5 and the first stirring rod 3 , and the torsion spring always gives the scraper 5 a torsion force to flip outward, so that the outer end of the scraper 5 always fits with the inner wall of the cylinder 1 .

[0020] A servo motor 6 is fixed on the upper end surface of the cylinder 1, and the rotating shaft of the servo motor 6 is coaxially fixedly connected with the stirring shaft 2, and the rotating shaft of the servo motor 6 always rotates alternately in forward and reverse directions.

[0021] A baffle plate 7 is provided at the opening position of the lower end of the cylinder 1. The right end of the baffle plate 7 is hinged to the lower end surface of the cylinder 1. The baffle plate 7 can open or close the lower end opening of the cylinder 1 by rotating along the hinge axis. The left end of the baffle plate 7 is connected to the lower end surface of the cylinder 1 through a buckle lock.

[0022] A plurality of legs 8 evenly distributed along the circumference are fixed to the lower end surface of the cylinder 1.

[0023] It is worth mentioning that all the scrapers 5 are inclined in the counterclockwise direction in the top view relative to the first stirring rod 3 .

[0024] When the utility model is in use, firstly, the baffle plate 7 is made to close the lower end opening of the cylinder 1, and then the feed raw materials to be mixed are added into the cavity of the cylinder 1 through the upper end opening of the cylinder 1, and the servo motor 6 is started. The servo motor 6 drives the stirring shaft 2 to rotate alternately in forward and reverse directions, and the first stirring rod 3 and the second stirring rod 4 rotate relative to each other to fully stir the materials. During the clockwise rotation of the first stirring rod 3, the blades in the upper and lower waistline directions can crush the materials to prevent the materials from being hardened on the outside; during the counterclockwise rotation of the first stirring rod 3, under the joint action of the torsion spring and the material resistance, the outer end of the scraper 5 is always in close contact with the inner wall of the cylinder 1, and the materials adhered to the inner wall of the cylinder 1 are scraped off to prevent the materials from adhering to the inner wall of the cylinder. After the stirring operation is completed, the baffle plate 7 is opened by the buckle lock to allow the fully stirred materials to be discharged from the lower end opening of the cylinder 1.

[0025] The utility model hinges a scraper 5 at the end of the first stirring rod 3 on the inner side, and drives it to rotate in the positive and negative directions along with the stirring shaft 2 through a servo motor 6.
