Description

Technical Field

[0001] This utility model relates to the field of feed mixer technology, and in particular to a device for preventing grass from getting tangled or stuck in a feed mixer. Background Technology

[0002] In the current field of feed processing equipment, single-shaft feed mixers are still used by some small and medium-sized breeding enterprises and individual users due to their simple structure and low initial investment cost. This type of equipment mainly relies on the rotation of the mixing plate on the main shaft to mix materials, but it has significant technical shortcomings when processing long wheat straw, rice straw and other coarse fiber materials. Because these materials have strong fiber toughness and poor flowability, they are easy to wrap around the main shaft and mixing plate surface during the mixing process. As the running time goes by, the wrapped straw will gradually accumulate and thicken, eventually causing the main shaft to jam between the main shaft and the equipment box. This failure will not only instantly increase the running resistance of the equipment, forcing the reducer and motor to work under overload for a long time, greatly accelerating the wear and aging of core components, and seriously shortening the overall service life of the equipment, but also require the operator to manually clean the straw at the jamming point after stopping the machine. The cleaning process requires disassembling part of the equipment structure, which is cumbersome, time-consuming and labor-intensive, often causing production interruption, bringing additional labor costs and time losses to users, and making it difficult to meet the needs of efficient and continuous feed processing.

[0003] To address the issues of grass entanglement and jamming in single-shaft mixers, the industry has gradually developed dual-shaft or triple-shaft feed mixers. Their design involves adding a secondary shaft and helical blades on it, utilizing the coordinated operation of multiple shafts to drive material circulation. This improves material dispersion within the mixing chamber, reduces excessive entanglement between the main shaft and material, and significantly improves anti-jamming performance compared to single-shaft equipment. However, the multi-shaft design also brings new technical limitations and application challenges. First, dual-shaft or triple-shaft structures require additional main shafts, secondary shafts, helical blades, and supporting transmission components, leading to a significant increase in overall manufacturing costs—30%-50% higher than single-shaft equipment of the same specifications—increasing the initial purchase burden for users. Second, the multi-shaft layout significantly increases the overall size of the equipment, requiring more space for installation and limiting its applicability in scenarios with limited farmland. Furthermore, the transmission connection structure between multiple shafts is more complex, requiring professional personnel for assembly and subsequent maintenance, increasing operational difficulty and time and cost for routine maintenance, making widespread application difficult in small and medium-sized farms.

[0009] Preferably, the bottom end of the motor mounting base is provided with two motor mounting reinforcing ribs, and the motor mounting reinforcing ribs are right-angled triangular structures;

[0010] One end of the motor mount reinforcing rib is fixedly connected to the bottom of the motor mount, and the other end is fixedly connected to the housing.

[0011] Preferably, the stirring mechanism includes a main shaft located in the middle of the housing; one end of the main shaft passes through the housing and is fixedly connected to the output end of the reducer.

[0012] A bearing is fixedly connected to the middle of the right side of the housing, and the other end of the main shaft passes through the housing and is rotatably connected to the bearing.

[0013] Preferably, a support shaft is fixedly connected to the box body, and a stirring plate is fixedly connected to the other end of the support shaft. Four stirring wheels are fixedly connected to the stirring plate.

[0014] The stirring wheel is screwed with a fixing screw, and the fixing screw is screwed to the stirring plate.

[0015] Preferably, the anti-tangle and anti-jamming mechanism includes two grass scrapers, which are arranged horizontally at the front of the box.

[0018] Preferably, the two lifting rings fixedly connected to the top of the box are distributed in the left and right directions along the open part of the top of the box.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This anti-stuffing and anti-jamming device for a feed mixer features a drive mechanism that is the core of the equipment's power output. The motor mounting base provides a stable mounting platform for the motor and reducer, ensuring their stable position during operation and preventing displacement due to vibration. After the motor starts, it generates power, which is transmitted to the reducer through the output end and belt. The reducer can adjust the speed and torque output of the motor, converting the high-speed rotation of the motor into a low-speed, high-torque output suitable for mixing operations. This meets the special power requirements of mixing long-fiber materials and prevents excessive material entanglement due to excessive speed or insufficient torque leading to weak mixing. The two right-angled triangular reinforcing ribs at the bottom of the motor mounting base utilize the structural stability of the triangle to enhance the load-bearing capacity and vibration resistance of the motor mounting base, reducing vibration transmission during the operation of the drive mechanism, further ensuring the stable operation of the motor and reducer, and ensuring efficient and reliable power transmission.

[0021] 2. This anti-stuffing and anti-jamming device for a feed mixer includes a mixing mechanism responsible for mixing the materials inside the chamber. The reducer outputs power to drive the connected main shaft to rotate. The main shaft is supported at both ends by fixed connections and bearings. The bearings reduce frictional resistance during rotation, ensuring smooth rotation and preventing uneven mixing or component wear due to unstable rotation. When the main shaft rotates, it drives a fixed support shaft to rotate synchronously, which in turn drives the mixing plate to rotate. Four mixing wheels on the mixing plate move together with the mixing plate, shearing, turning, and mixing long-fiber materials and other feed components inside the chamber during rotation, ensuring thorough blending and uniform feed mixing. Fixing screws securely fix the mixing wheels to the mixing plate, preventing them from loosening or falling off during high-speed rotation, ensuring long-term stable operation of the mixing mechanism, and preventing loose components from affecting the mixing effect or causing equipment failure.

[0022] 3. This anti-grass entanglement and anti-grass jamming device for feed mixers is key to solving the problem of grass entanglement and jamming in traditional mixers. Two scraper blades are horizontally arranged at the front of the housing and symmetrically distributed on the left and right sides, ensuring that the mixing plate can fully contact the scraper hooks on the scraper blades when rotating. The scraper hooks have a specific angle, and when the mixing plate rotates with the main shaft and passes the scraper hook position, the scraper hook can accurately hook the long fiber material wrapped around the surface of the mixing plate and forcibly remove it from the mixing plate, allowing the material to fall back into the housing to continue participating in the mixing. This real-time cleaning method can effectively prevent the continuous accumulation of material on the mixing plate, avoid the main shaft and housing jamming caused by material accumulation, and ensure the normal operation of the equipment. The fixing bolts and fixing nuts cooperate to firmly fix the scraper blades to the housing, ensuring that the scraper blades remain in the same position during the operation of the equipment, ensuring the matching accuracy between the scraper hooks and the mixing plate, maintaining a stable anti-grass entanglement and anti-grass jamming effect over a long period of time, and reducing equipment downtime for cleaning and maintenance costs.

The open top allows for easy addition of materials to be mixed, meeting the needs of batch processing. Four support legs 2 are symmetrically distributed at the bottom of the housing 1, providing stable support for the entire equipment and preventing significant shaking of the housing 1 during mixing, ensuring the overall operational stability of the equipment. After mixing, the uniformly mixed feed can be naturally discharged through the front outlet 3, ensuring a smooth discharge process and reducing feed residue. The two lifting rings 19 at the top are mainly used for the transportation and installation of the equipment, facilitating the movement of the equipment to a designated location using lifting tools, reducing the difficulty of manual handling, and improving the convenience of equipment installation and relocation.

[0041] The drive mechanism is the core of the equipment's power output. The motor mounting base 4 provides a stable mounting platform for the motor 5 and the reducer 6, ensuring their stable position during operation and preventing displacement due to vibration. After the motor 5 starts, it generates power and transmits it to the reducer 6 through the output end and belt 7.

[0046] The mixing mechanism is responsible for mixing the materials in the housing 1. After the reducer 6 outputs power, it drives the main shaft 8 connected to it to rotate. The two ends of the main shaft 8 are supported by fixed connections and bearings 9 respectively. The bearings 9 can reduce the frictional resistance when the main shaft 8 rotates, ensuring that the main shaft 8 rotates in a stable state and avoiding uneven mixing or wear of parts due to unstable rotation. When the main shaft 8 rotates, it drives the support shaft 10 fixed on it to rotate synchronously. The support shaft 10 further drives the mixing plate 11 to rotate. The four mixing wheels 12 on the mixing plate 11 move together with the mixing plate 11. During the rotation, they shear, turn and mix the long fiber materials and other feed components in the housing 1, so that the various materials are fully integrated and the feed is mixed evenly. The fixing screws 13 firmly fix the mixing wheels 12 to the mixing plate 11 to prevent the mixing wheels 12 from loosening or falling off during high-speed rotation, ensuring the long-term stable operation of the mixing mechanism and avoiding the mixing effect or equipment failure due to loose parts.

[0047] Furthermore, the anti-tangle and anti-jamming mechanism includes two grass scrapers 14, which are arranged horizontally at the front of the housing 1.

The mixing continues inside the housing 1; this real-time cleaning method can effectively prevent materials from continuously accumulating on the mixing plate 11, avoiding jamming of the main shaft 8 and housing 1 due to material accumulation, and ensuring normal operation of the equipment; the fixing bolts 16 and fixing nuts 17 cooperate to firmly fix the grass scraper 14 to the housing 1, ensuring that the position of the grass scraper 14 remains unchanged during equipment operation, ensuring the matching accuracy between the grass scraper hook 15 and the mixing plate 11, maintaining a stable anti-grass entanglement and grass jamming effect for a long time, and reducing equipment downtime for cleaning and maintenance costs;
