Description

Technical Field

[0001] This utility model relates to the field of livestock machinery and equipment, and in particular to a six-steel double-wheel rotary milking machine chassis. Background Technology

[0002] In modern large-scale dairy farms, rotary milking machines have become the mainstream equipment due to their high efficiency and high degree of automation. Because of the continuous nature of milking operations, the chassis system of rotary milking machines operates under near-constant, high-load conditions year-round, and the working environment is generally characterized by high humidity and susceptibility to corrosion. This places extremely stringent requirements on the structural strength, long-term operational stability, corrosion resistance, and ease of maintenance of the chassis system.

[0003] Currently, most widely used rotary milking machines employ a single-rail design, with a typical configuration of approximately 0.85 support points and 1.67 nylon wheel sets per cow position. However, this single-rail structure, with its relatively sparse support points and insufficient wheel sets, often leads to severe periodic damage to its core load-bearing component—the rail—under the combined effects of prolonged heavy-load cyclic stress and high humidity. This damage manifests primarily as cracking and bending deformation of the rail web and corrosion and fracture of the flanges. These structural damages not only directly threaten the safe and stable operation of the rotary milking machine, potentially causing production interruptions and safety risks, but also, due to the highly compact layout of the rotary milking machine chassis to save installation space, make maintenance of these rail damages extremely difficult, often requiring significant time and cost, thus significantly increasing the operational burden on the dairy farm.

[0004] Therefore, how to develop a six-steel double-wheel rotary milking machine chassis that can effectively resist long-term heavy loads and harsh environmental corrosion, and avoid premature failure of key track components, has become a technical problem that urgently needs to be solved by people in this field. Utility Model Content

[0005] The purpose of this invention is to provide a six-steel double-wheel rotary milking machine chassis that can effectively resist long-term heavy loads and harsh environmental corrosion, and avoid premature failure of key track components.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model discloses a six-steel double-wheel rotary milking machine chassis, including an upper rail, a lower rail, a support base, and roller assemblies. The lower rail is fixedly connected to the top of the support base by fastening bolts. The upper rail and the lower rail are concentrically arranged, and multiple roller assemblies are sandwiched between the upper rail and the lower rail. Each roller assembly includes two rollers and a corresponding roller frame. The roller frame is mounted on the rollers, and adjacent roller assemblies are connected by the roller frame.

[0008] Both the upper and lower rails include an I-shaped rail body and a reinforcing web. The two reinforcing webs are symmetrically arranged on the left and right sides of the web of the I-shaped rail body. The upper and lower ends of the reinforcing webs are fixedly connected to the upper and lower wing plates of the I-shaped rail body, respectively. The top of the roller makes rolling contact with the bottom of the upper rail, and the bottom of the roller makes rolling contact with the top of the lower rail.

[0009] Both the outer surfaces of the upper and lower rails are provided with a hot-dip galvanized layer.

[0010] Preferably, the lower wing plate of the lower track is fitted to the top of the support base; a track pressure plate is provided on the top of the lower wing plate of the lower track, and the track pressure plate, the lower wing plate of the lower track and the support base are fastened together by the fastening bolts.

[0011] Preferably, the roller is a tracked nylon wheel.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] This utility model discloses a six-steel double-wheel rotary milking machine chassis. By symmetrically adding reinforcing webs to both sides of the web of the upper and lower I-shaped track main body, the overall structural strength and bending resistance of the track are significantly improved. This allows it to withstand the cyclic stress caused by the long-term high-load operation of the rotary milking machine, effectively overcoming the problems of web cracking, bending, and wing plate corrosion fracture that are prone to occur in traditional single-track structures, and greatly extending the service life of the chassis system. The track surface is treated with hot-dip galvanizing, giving it excellent moisture-proof, damp-proof, and corrosion-resistant properties, making it particularly suitable for the high-humidity working environment of pastures, ensuring the long-term robustness of the structure. Durable; at the same time, it innovatively configures a roller frame and two track nylon wheels at each cow position. This double-wheel support structure effectively disperses the force, reduces single-point pressure, makes the track load distribution more uniform and stable, and reduces the risk of damage caused by local stress concentration. The use of track nylon wheels with excellent self-lubricating properties as rollers not only results in low frictional resistance and low operating noise, but also eliminates the maintenance step of regularly adding lubricating oil in the traditional structure, achieving maintenance-free operation. This reduces long-term operation and maintenance costs and avoids the pollution that lubricating oil may cause, helping to maintain a clean and hygienic milking environment.

It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0021] like Figure 1-4 As shown, a six-steel double-wheel rotary milking machine chassis includes an upper rail 1, a lower rail 2, a support base 3, and roller assemblies. The lower rail 2 is fixedly connected to the top of the support base 3 by fastening bolts 9. The upper rail 1 and the lower rail 2 are concentrically arranged, and multiple roller assemblies are sandwiched between the upper rail 1 and the lower rail 2. Each roller assembly includes two rollers 4 and a corresponding roller frame 5. The roller frame 5 is mounted on the rollers 4, and adjacent roller assemblies are connected by the roller frame 5.

[0022] The upper track 1 and the lower track 2 both include an I-shaped track body 6 and a reinforcing web 7. The two reinforcing webs 7 are symmetrically arranged on the left and right sides of the web of the I-shaped track body 6, and the upper and lower ends of the reinforcing web 7 are fixedly connected to the upper wing plate and the lower wing plate of the I-shaped track body 6, respectively. The top of the roller 4 is in rolling contact with the bottom of the upper track 1, and the bottom of the roller 4 is in rolling contact with the top of the lower track 2.

[0023] Both the outer surfaces of the upper track 1 and the lower track 2 are provided with a hot-dip galvanized layer.

[0024] Specifically, the surfaces of the upper track 1 and the lower track 2 are hot-dip galvanized, which provides good moisture-proof and damp-proof performance, and the structure is sturdy and durable.

[0025] Specifically, a reinforcing web plate 7 is provided on each of the left and right sides of the web of the I-shaped track body 6. This structure significantly enhances the load-bearing capacity of the track, making it more stable and reliable, and effectively extending its service life.

[0026] Specifically, the lower wing plate of the lower track 2 is fitted to the top of the support base 3; a track pressure plate 8 is provided on the top of the lower wing plate of the lower track 2, and the track pressure plate 8, the lower wing plate of the lower track 2 and the support base 3 are fastened together by the fastening bolts 9.

[0027] Specifically, the roller 4 is a tracked nylon wheel.

[0028] Specifically, each cow position is equipped with a roller frame 5 and two rollers 4. This configuration effectively disperses the force and reduces the pressure at a single point. At the same time, the rollers 4, made of track nylon wheel material, have excellent self-lubricating properties, requiring no additional lubricating oil, achieving maintenance-free operation, and helping to maintain a clean and hygienic working environment.

[0029] This utility model discloses a six-steel double-wheel rotary milking machine chassis. By symmetrically adding reinforcing webs to both sides of the web of the upper and lower I-shaped track main body, the overall structural strength and bending resistance of the track are significantly improved. This allows it to withstand the cyclic stress caused by the long-term high-load operation of the rotary milking machine, effectively overcoming the problems of web cracking, bending, and wing plate corrosion fracture that are prone to occur in traditional single-track structures, and greatly extending the service life of the chassis system. The track surface is treated with hot-dip galvanizing, giving it excellent moisture-proof, damp-proof, and corrosion-resistant properties, making it particularly suitable for the high-humidity working environment of pastures, ensuring the long-term robustness of the structure. Durable; at the same time, it innovatively configures a roller frame and two track nylon wheels at each cow position.
