Description

Technical Field

[0001] The utility model belongs to the technical field of feed mixing and stirring devices, and particularly relates to a feed mixing and stirring device. Background Technique

[0002] Feed mixing and stirring is a key step in modern animal husbandry, aiming to ensure that animals obtain nutritionally balanced feed. From poultry to livestock, from aquatic animals to pets, there are significant differences in the feed requirements of different species and growth stages of animals. Moreover, the types of feed raw materials are extremely extensive, including but not limited to grains, beans, oil crops, forage, vegetables, fruit residues, fish meal, bone meal, minerals, vitamins, and various additives. These raw materials are not only rich in nutrition but also have their own characteristics. Therefore, in modern aquaculture, in order to meet the nutritional requirements of different species of animals, it is usually necessary to proportion and fully mix a variety of raw materials to prepare feed that meets specific nutritional standards. Most of the existing feed mixing and stirring devices have a single function and cannot meet the feed requirements of a wide range of animal species. Content of the Utility Model

[0003] The purpose of the utility model is to provide a feed mixing and stirring device to solve the existing problems.

[0004] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0005] The utility model is a feed mixing and stirring device, including an inner stirring barrel. The outer peripheral side of the inner stirring barrel is rotatably connected with an outer protective shell. The outer peripheral side of the outer protective shell is bolt-fixed with a support fixing plate. The lower surface of the support fixing plate is welded with four support columns. The cooperation of the support fixing plate and the support columns provides a solid foundation for the mixing and stirring device, ensuring that the equipment will not be displaced or damaged due to vibration or uneven weight distribution during operation. The support columns allow users to adjust the position and height of the equipment according to needs, making it more suitable for different working environments and requirements.

[0006] Furthermore, a limit fixing block is bolt-fixed on the upper surface of the inner stirring barrel. A transmission belt is rotatably connected to the outer peripheral side of the inner stirring barrel. The transmission belt drives the inner stirring barrel to rotate. The rotation of the inner stirring barrel can reduce or eliminate the possibility of materials forming dead corners near the barrel wall, ensuring that even the materials near the barrel wall can be fully mixed.

[0007] Furthermore, a rotating support column is rotatably connected to the inner side of the drive belt. A drive gear is meshed and connected to the upper end of the rotating support column. The drive gear is meshed and connected to a stirring screw. A drive motor is fixedly connected to the upper end of the stirring screw. The lower surface of the drive motor is bolted and fixed to the outer protective shell. A feed inlet is formed in the upper surface of the outer protective shell. A feed inlet baffle is hingedly connected to the inner wall of the feed inlet. The lower surface of the feed inlet is fixedly connected to an inner stirring barrel cover. The lower end of the inner stirring barrel cover is rotatably connected to the inner stirring barrel. The circumferential side of the limit fixing block is rotatably connected to the drive gear. The lower surface of the inner stirring barrel cover is fixedly connected to the inner stirring barrel. The stirring screw passes through the outer protective shell and the inner stirring barrel cover and extends to the lower end of the inner stirring barrel. A plurality of stirring blades are fixedly connected to the circumferential side of the stirring screw. A barrel wall scraper is fixedly connected to the circumferential side of the stirring screw. The barrel wall scraper can improve the flow characteristics of the material in the barrel, especially when dealing with materials with poor fluidity, which helps to maintain good mixing dynamics. An outlet control valve is bolted and fixed to the lower surface of the inner stirring barrel. A finished feed trough is arranged below the outlet control valve.

[0008] Furthermore, both side surfaces of the rotating support column are rotatably connected to the outer protective shell. A gear is arranged at the upper end of the rotating support column. The gear is meshed and connected to the drive gear. A gear is arranged at the upper end of the stirring screw. The gear is meshed and connected to the drive gear. During operation, the drive motor is started first. The drive motor drives the stirring screw to rotate. Then the stirring screw drives the stirring blades and the barrel wall scraper to perform stirring and mixing. At the same time, the rotation of the stirring screw causes the meshed drive gear to rotate. Further, the drive gear drives the rotating support column to rotate through meshing connection. Then the rotating support column drives the inner stirring barrel to rotate through a track. When the inner stirring barrel itself participates in rotation, the combined action of the inner stirring barrel and the stirring blades can generate a more complex material flow pattern, thereby accelerating the mixing process of the material. This design can ensure the uniform distribution of all components throughout the stirring barrel. At the same time, the simultaneous rotation of the inner stirring barrel and the stirring blades can significantly shorten the time required to reach the required mixing degree, improving the production efficiency.

[0009] Further, the inner wall scraper is located below the inner mixing barrel. The size and shape of the barrel wall scraper are adapted to the inner mixing barrel. The barrel wall scraper can help prevent materials from sticking to the barrel wall during the mixing process, which is particularly important when dealing with high-humidity or viscous materials. The barrel wall scraper can also continuously clean the materials adhering to the barrel wall, ensuring the cleanliness inside the mixing barrel and the uniform mixing of materials. The function of the barrel wall scraper is not only cleaning, but also promoting the circulating flow of materials, helping the materials to be evenly distributed in the barrel, thereby improving the mixing efficiency and quality. After the mixing process ends, the barrel wall scraper can ensure that there is no material residue on the barrel wall, which not only reduces waste, but also simplifies the cleaning process, reducing the cleaning cost and time.

[0010] Further, the bottom of the finished feed trough is designed to be inclined. The upper surface of the discharge control valve is connected by a pipeline to the inner mixing barrel. The size and shape of the discharge control valve are adapted to the finished feed trough. The inclined bottom surface design can utilize the help of gravity, making the mixed feed flow to the outlet more easily and smoothly, avoiding the problems of material accumulation and retention that may occur in the flat-bottom design. The inclination angle makes the materials not easily remain at the corners of the trough bottom, thus reducing material waste and also facilitating the clean switching of materials in subsequent batches.

[0011] The utility model has the following beneficial effects:

[0012] During the operation of the utility model, the driving motor is first started. The driving motor drives the stirring screw to rotate, and then the stirring screw drives the stirring blades and the barrel wall scraper to carry out stirring and mixing. At the same time, the rotation of the stirring screw causes the meshing-connected transmission gear to rotate. Further, the transmission gear drives the rotating support column to rotate through meshing connection. Then, the rotating support column drives the inner mixing barrel to rotate through the track. When the inner mixing barrel itself participates in rotation, the combined action of the inner mixing barrel and the stirring blades can generate a more complex material flow pattern, thereby accelerating the material mixing process. This design can ensure the uniform distribution of all components throughout the mixing barrel. At the same time, the simultaneous rotation of the inner mixing barrel and the stirring blades can significantly shorten the time required to reach the required mixing degree, improving the production efficiency.

[0013] The barrel wall scraper of the utility model can help prevent materials from sticking to the barrel wall during the mixing process, which is particularly important when dealing with high-humidity or viscous materials. They can continuously clean the materials adhering to the barrel wall, ensuring the cleanliness inside the mixing barrel and the uniform mixing of materials. The function of the barrel wall scraper is not only cleaning, but also promoting the circulating flow of materials, helping the materials to be evenly distributed in the barrel, thereby improving the mixing efficiency and quality.

[0014] The utility model provides a firm foundation for the mixing and stirring device through the cooperation of the supporting fixed disk and the supporting column, ensuring that the equipment will not be displaced or damaged due to vibration or uneven weight distribution during operation. The supporting column allows users to adjust the position and height of the equipment according to needs, making it more suitable for different working environments and requirements.

[0015] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. Description of the Drawings
