Description

Technical Field

[0001] This utility model relates to the field of livestock machinery technology, specifically to a ruminant mixer suitable for coarse fiber feed. Background Technology

[0002] Currently, common ruminant feed mixers on the market have many technical shortcomings when processing high-fiber raw materials. Traditional equipment mostly uses a single-stage cutting system, which has poor crushing effect on long-fiber raw materials, resulting in insufficient feed mixing uniformity and affecting the digestibility and absorption efficiency of ruminants. At the same time, the single-shaft structure of conventional mixers is prone to fiber entanglement during high-speed operation, which not only increases the motor load and energy consumption, but also accelerates the wear of mechanical parts.

[0003] Furthermore, because coarse fiber raw materials often contain high moisture content, they easily adhere to the inner wall of the mixing chamber during the mixing process, forming stubborn clumps. This not only reduces the effective volume but also breeds mold, requiring frequent shutdowns for cleaning and severely impacting production efficiency. Although existing equipment improves the cutting effect by increasing the number of blades or increasing the rotation speed, this often leads to a sharp increase in power consumption and fails to fundamentally solve the problems of fiber entanglement and material sticking to the chamber walls. There is an urgent need for a new type of mixer structure that can balance efficient cutting, uniform mixing, and easy maintenance. Utility Model Content

[0004] To solve the above problems, this utility model provides the following technical solution: a ruminant mixer suitable for coarse fiber feed, including a bin, a drive motor, a mixing shaft, a feed inlet and a discharge outlet. A primary coarse cutting device is provided below the feed inlet. An adjustable-gap rotating chaff cutter roller is installed inside the primary coarse cutting device, and its lower end is welded to the bin. A secondary fine cutting device is provided at the bottom of the bin, which is equipped with a high-speed rotating hammer blade assembly. The secondary fine cutting device is connected to the mixing shaft through a spline shaft and a hydraulic locking nut. Spiral ribbon blades and straight blades are alternately fixed on the surface of the mixing shaft.

[0005] Preferably, the inner wall of the chamber is lined with a high-polymer wear-resistant plate, and a scraper that can rotate with the main shaft is installed inside.

[0006] Preferably, the distance between the blade rollers of the primary roughing device is adjusted by an external handle, ranging from 3 to 10 cm.

[0007] Preferably, the discharge port is a bottom-opening gate, which is controlled to open and close by a cylinder.

[0008] Preferably, the drive system is a hydraulic motor, which is connected to an external power unit via hydraulic pipelines.

[0009] Compared with existing technologies, the beneficial effects of this utility model are as follows: A primary coarse-cutting device, consisting of an adjustable-gap rotating chaff cutter roller, is installed below the feed inlet. This, combined with a secondary fine-cutting device at the bottom of the silo, connected via a splined shaft and hydraulic locking nut, and equipped with a high-speed rotating hammer assembly, achieves step-by-step pulverization of coarse fibers. Alternating spiral ribbon blades and straight blades fixed on the mixing shaft improve mixing uniformity. The high-polymer wear-resistant plate on the inner wall of the silo and the scraper that rotates with the main shaft reduce wear and residue. The use of a hydraulic motor drive system and a cylinder-controlled bottom-opening gate discharge port makes the equipment more stable and reliable in operation. This design improves the processing quality and production efficiency of ruminant feed. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] like Figure 1 As shown, the ruminant mixer for coarse fiber feed in this embodiment includes a bin 1, a drive motor 2, a mixing shaft 3, a feed inlet 4, and a discharge outlet 5. A primary coarse cutting device 6 is provided below the feed inlet 4. An adjustable-gap rotating chaff cutter roller is installed inside the primary coarse cutting device 6. The bin 1 is welded to it. A secondary fine cutting device 7 is provided at the bottom of the bin 1. A high-speed rotating hammer blade assembly is installed inside the secondary fine cutting device 7. The secondary fine cutting device 7 is connected to the mixing shaft 3 through a spline shaft and a hydraulic locking nut. Spiral ribbon blades 8 and straight blades 9 are alternately fixed on the surface of the mixing shaft 3.

[0016] The inner wall of the chamber 1 is lined with a high-polymer wear-resistant plate 10, and a scraper 11 that can rotate with the main shaft is installed inside to reduce wear and residue.

[0017] The distance between the blade rollers of the primary roughing device 6 is adjusted by the external handle 12, ranging from 3 to 10 cm.

[0018] The discharge port 5 is a bottom-opening gate, which is controlled by cylinder 13 to open and close.

[0019] The drive system is a hydraulic motor 14, which is connected to an external power unit through a hydraulic pipeline 15, making the equipment operation more stable and reliable.

[0020] The working principle of this utility model is as follows: After the coarse fiber ruminant feed enters through the feed inlet 4, it is first coarsely cut by the adjustable-gap rotating chaff cutter roller in the primary coarse cutting device 6. The spacing can be adjusted within the range of 3-10cm by the external handle 12. After the coarsely cut material falls into the bin 1, it is stirred and mixed by the spiral ribbon blades 8 and straight blades 9 that are alternately fixed on the surface of the stirring shaft 3. At the same time, the high-speed rotating hammer blade group in the secondary fine cutting device 7 at the bottom of the bin 1 is connected to the stirring shaft 3 through the spline shaft and hydraulic locking nut to finely cut the material. The scraper 11 that can rotate with the main shaft, together with the high-polymer wear-resistant plate 10 lined on the inner wall of the bin 1, effectively prevents material residue. After processing, the cylinder 13 controls the opening of the bottom-opening gate discharge port 5 to unload the material. Throughout the process, the hydraulic motor 14 is connected to the external power unit through the hydraulic pipeline 15 to provide power, realizing the efficient processing of coarse fiber feed.
