Description

Technical Field

[0001] This utility model relates to the field of mixed feed feeding equipment, and in particular to a mixed feed feeding system. Background Technology

[0002] Currently, traditional feeding systems for ruminant feed transportation have many drawbacks. In existing technologies, powdered roughage and concentrates are often fed separately. Trucks must unload pellets and powdered concentrates into their respective feed hoppers. The feed is then transported to the storage silo via scraper conveyors, belt conveyors, and elevators. This separate transportation model results in an increased number of feed hoppers and conveying equipment, leading to dispersed equipment installation and occupying a significant amount of space. For ranches with limited space resources, this severely restricts the rational planning and efficient utilization of the site.

[0003] Furthermore, since the elevators reach heights of tens of meters, not only are towers for fixation and maintenance required, but lightning protection devices also need to be installed. This not only increases construction costs but also makes daily maintenance more complicated. At the same time, the numerous dispersed conveying devices are prone to malfunctions during operation, resulting in high maintenance costs and difficulties, and reducing the efficiency and stability of feed conveying.

[0004] Existing technologies are insufficient to meet the farms' needs for compact layouts, efficient conveying, and low-cost maintenance of feed feeding systems. Therefore, there is an urgent need to develop a mixed feed feeding system that can integrate the feeding processes of powdered roughage and concentrate, reduce equipment footprint, and ensure reliable conveying. Utility Model Content

[0010] Preferably, the feed distributor is installed on the upper part of the support frame and above the weighing bin. Installing the feed distributor on the upper part of the support frame and above the weighing bin effectively utilizes vertical space, optimizes the overall layout, and avoids the problem of scattered equipment occupying a large area. This installation position allows the feed distributor to directly distribute feed to the weighing bin below, shortening the feed conveying path, reducing energy loss and time costs during the conveying process, and facilitating the connection of feed from the feed distributor to the weighing bin, ensuring the efficiency and continuity of the feed conveying process, and further improving the operating efficiency and space utilization of the mixed feed feeding system.

[0011] Preferably, a fluidizing disc is connected to the bottom of the silo tank; a buffer tank is connected to the air compressor outlet; and the outlet of the buffer tank is connected to the upper and lower parts of the silo tank and the fluidizing disc.

Simultaneously, the flexible combination of the feed pump and nozzle facilitates adjustment of the liquid feed addition amount according to actual needs, enhancing the applicability and functionality of the mixed feed feeding system.

[0014] Preferably, the weighing bin includes a bin body; the outer wall of the bin body is mounted on a bracket via a weighing sensor. The weighing bin, mounted on the bracket via a weighing sensor on the outer wall of the bin body, can accurately measure the weight of the feed inside the bin in real time, providing data support for precise feed formulation. This installation method utilizes the sensitive characteristics of the weighing sensor to convert changes in the bin body's weight into an electrical signal output, facilitating the system's rapid acquisition of feed weight information. Compared to traditional weighing methods, this method is more efficient and accurate, and its stable structure effectively avoids the impact of shaking caused by feed entering and leaving the bin on weighing accuracy. It also reduces manual weighing steps, lowers labor costs, and improves the automation level and efficiency of the mixed feed feeding system.

[0015] Preferably, eight roughage bins are installed; four roughage bins are installed on each side of the scraper conveyor; a fourth screw conveyor is installed inside each roughage bin; the outlet of the fourth screw conveyor is connected to the scraper conveyor. This layout of eight roughage bins, with four on each side of the scraper conveyor, makes full use of space, significantly increasing the storage capacity of roughage and enabling the classified storage and management of various roughages. The fourth screw conveyor inside the roughage bins can stably and efficiently transport the roughage to the scraper conveyor, ensuring continuous roughage output and avoiding the impact of feed accumulation or blockage on conveying efficiency. Simultaneously, the close cooperation between the scraper conveyor and multiple roughage bins allows for the mixing of different types of roughage, meeting the diverse feed supply needs of the ranch, enhancing the practicality and adaptability of the mixed feed feeding system, and providing strong support for the efficient conveying and precise proportioning of ranch feed.

[0016] Preferably, the scraper conveyor's outlet is connected to a distribution pipe; both ends of the distribution pipe have outlets on their bottom surfaces; each outlet connects to a mixing bin; and the outlet of the first screw conveyor is connected to the middle of the distribution pipe.
