Description

Technical Field

[0001] This utility model relates to the field of feed mixing technology, specifically a dry and wet feed mixing device. Background Technology

[0002] In animal husbandry and aquaculture, the uniformity of feed mixing directly affects animal nutrient intake and growth efficiency. Feed mixing equipment is a core component of feed processing; its function is to uniformly mix different types and characteristics of raw materials according to the formula ratio, ensuring that animals receive nutritionally balanced feed.

[0003] Direct mixing of dry and wet feed is one method of mixing dry and wet feed. Traditional methods of mixing dry and wet feed mainly involve manual stirring or simple mechanical mixing equipment, which has the following problems: Manual mixing is inefficient and makes it difficult to ensure thorough mixing of dry and wet feed, easily leading to clumping or stratification, which affects palatability and nutritional balance. Existing mixing equipment directly pours all the dry feed into the wet feed for mixing, which easily results in the accumulation of dry feed and the formation of clumps of wet feed, resulting in uneven mixing and low efficiency. Utility Model Content

[0004] This invention addresses the aforementioned shortcomings of existing technologies by providing a dry and wet feed mixing device. A sieve ensures that dry materials are evenly distributed onto the surface of wet materials and promptly mixed by a stirring shaft, preventing localized accumulation. Through "dry material vibrating sieving + wet material bidirectional shearing," the device simultaneously completes the feeding of dry materials and the mixing of wet materials, improving the uniformity and efficiency of the mixing process. To achieve the above objectives, this utility model provides the following technical solution: A dry and wet feed mixing device includes a U-shaped mixing box. The lower end of the mixing box is provided with a support leg, and the upper end of the mixing box is provided with a top cover. Below the top cover is a sieve for holding dry feed. The sieve can be shaken to evenly scatter the dry feed below. A side feed inlet for adding wet feed is connected to one side of the mixing box. The side feed inlet is provided with a side cover. A stirring shaft with opposite rotation direction is provided inside the mixing box. A discharge port is provided at the bottom of the mixing box.

[0005] Preferably, both the top cover and the side cover are provided with handles at their upper ends. Preferably, a plate for blocking feed is inserted into the side wall of the discharge port, and a pull rod is provided at one end of the plate. Preferably, the impellers of the two impeller shafts are staggered, one end of the two impeller shafts is connected by gear meshing, and the other end of one impeller shaft is connected to a first motor. Preferably, the mixing chamber is connected to a guide rail, the lower end of the sieve is engaged with the guide rail through a sliding sleeve, the upper end of the mixing chamber is provided with a second motor, the output shaft of the second motor is connected to a drive disk, and the drive disk is connected to one end of the sieve through a drive rod.
