Description

Technical Field

[0001] This utility model relates to the technical field of milk collection equipment, specifically to a support and rotation mechanism for a rotary milking machine. Background Technology

[0002] A rotary milking machine is a milk collection device, mainly composed of a milking table, a rotary table, a driver, etc. The milking tables are arranged in a ring, and the cows stand on the milking tables at certain intervals, allowing multiple cows to be milked at the same time. The driver drives the rotary table to rotate, and the rotary table is used to move the cows through each milking station in sequence, realizing an efficient milking process.

[0003] In the prior art, the turntable is generally installed on a support and rotation mechanism consisting of upper and lower rails and pulleys to reduce the resistance during rotation. However, the existing upper and lower rails are prone to detaching from the pulleys during rotation, causing the upper and lower rails to rotate eccentrically, which in turn affects the normal operation of the entire turntable milking machine. Utility Model Content

[0004] In view of this, the problem to be solved by this utility model is to provide a support rotation mechanism for a rotary milking machine.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A support and rotation mechanism for a rotary milking machine includes an upper rail, double-sided grooved wheels, a lower rail, and a wheel frame assembly;

[0007] Each wheel body of the double-sided grooved wheel has an inclined transition surface constructed on its circumference to the outer edge, and the upper rail is provided with an inclined abutment surface corresponding to the inclined transition surface.

[0008] The double-sided grooved wheel slides into the lower rail through the groove between the wheel bodies and slides into the upper rail through the inclined transition surface. Adjacent double-sided grooved wheels are connected by wheel frame assemblies.

[0009] The axial cross section of the wheel body with the inclined transition surface increases in the direction close to the wheel axle.

[0010] The bottom of the upper track is also fixedly connected to an annular plate, the middle of which is sunken and the two sides are constructed with inclined abutment surfaces.

[0011] The width of the upper track is greater than the width of the lower track.

[0012] The wheel frame assembly includes a rectangular frame and connecting rods;

[0013] The wheel frame assembly has threaded through holes in its transverse direction, and the two sides of the double-sided grooved wheel have round holes. Fasteners are threaded to the threaded through holes and sleeved to the round holes.

[0014] One end of the connecting rod is fixedly connected to the rectangular frame, and the other end is rotatably connected to the adjacent rectangular frame.

[0015] The lower track includes several arc-shaped lower track segments, and adjacent arc-shaped lower track segments are fastened together by fixed steel clamps on both sides.

[0016] The upper track includes several arc-shaped upper track segments, and adjacent arc-shaped upper track segments are fastened together by perforated square steel plates at both ends.

[0017] The advantages and positive effects of this utility model are:

[0018] The double-sided grooved wheel is slidably embedded in the lower rail through grooves, thus preventing the lower rail from slipping off the double-sided grooved wheel; the double-sided grooved wheel is slidably embedded in the upper rail through an inclined transition surface, thus preventing the upper rail from slipping off the double-sided grooved wheel; the width of the upper rail is greater than the width of the lower rail, maximizing the contact area between the double-sided grooved wheel and the upper rail, making the upper rail more stable during rotation, and further increasing the stability of the turntable on the upper rail during rotation.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] like Figures 1 to 4 As shown, this utility model provides a support and rotation mechanism for a rotary milking machine, including an upper rail 1, a double-sided grooved wheel 2, a lower rail 3, and a wheel frame assembly 4; the double-sided grooved wheel 2 is located between the upper rail 1 and the lower rail 3, and both the upper rail 1 and the lower rail 3 are designed with a ring structure, which can achieve a 360-degree rotation; the double-sided grooved wheel 2 includes a wheel axle 24 and two wheel bodies 23 located at both ends of the wheel axle 24.

[0032] Each wheel body 23 of the double-sided grooved wheel 2 has an inclined transition surface 21 on its circumference to the outer edge. The upper rail 1 is provided with an inclined abutment surface 61 corresponding to the inclined transition surface 21. The two sets of inclined abutment surfaces 61 abut against the inclined transition surface 21 of the double-sided grooved wheel 2. In the axial direction, the two sets of inclined abutment surfaces 61 limit the double-sided grooved wheel 2, thereby making the double-sided grooved wheel 2 slide relative to the upper rail 1 and preventing the upper rail 1 from slipping off relative to the double-sided grooved wheel 2.

[0033] The width of the lower track 3 corresponds to the width of the groove 22 between the wheel bodies 23, so that the double-grooved wheel 2 slides into the lower track 3 through the groove 22 between the wheel bodies 23, thus preventing the lower track 3 from slipping off the double-grooved wheel 2;

[0034] This design maximizes the contact area between the upper rail 1 and the double-sided grooved wheel 2 while preventing slippage from the upper rail 1, making the upper rail 1 more stable during rotation and preventing the turntable connected to the upper rail 1 from shaking. The lower rail 3 is slidably embedded in the groove 22, ensuring that it cannot detach from the double-sided grooved wheel 2 in the axial direction. In the radial direction, the combined weight of the turntable, the upper rail 1, and the double-sided grooved wheel 2 acts on the lower rail 3, thus preventing tilting and maximizing the stability of the sliding between the lower rail 3 and the double-sided grooved wheel 2. Adjacent double-sided grooved wheels 2 are connected by wheel frame assembly 4.

[0035] Specifically, the axial cross section of the wheel body 23 with the inclined transition surface 21 increases in the direction close to the wheel axle 24. Correspondingly, the inclined abutment surface 61 on the upper track 1 is in the opposite direction to the inclined transition surface 2, so that the two sides of the upper track 1 cover the two sides of the double-sided grooved wheel 2 respectively, thus avoiding slippage.

[0036] Specifically, an annular plate 6 is fixedly connected to the bottom of the upper track 1. The annular plate 6 is welded to the upper track 1. The middle part of the annular plate 6 is sunken, and the inclined abutment surfaces 61 are constructed on both sides.

[0037] The design of the annular plate 6 makes it easier to process the inclined abutment surface 61 compared to the already formed upper track 1. On the other hand, even if there is a processing error that prevents it from sliding with the double-sided grooved wheel 2, only the annular plate 6 needs to be replaced, and the entire upper track 1 does not need to be replaced.

[0038] Specifically, the width of the upper track 1 is greater than the width of the lower track 3. The upper track 1 is made of I-beam steel rail, and the larger contact area increases the stability of the connection with the turntable.

[0039] like Figure 5 As shown, specifically, the wheel frame assembly 4 includes a rectangular frame 41 and a connecting rod 42;

[0040] The rectangular frame 41 has threaded through holes on its lateral side, and the double-sided grooved wheel 2 has round holes on both sides. The fastener is threadedly connected to the threaded through holes and sleeved to the round holes. The threaded connection makes the fastener fixedly connected to the rectangular frame 41, and the sleeved connection makes the double-sided grooved wheel 2 rotatably connected to the rectangular frame 41. The fastener is a bolt.

[0041] One end of the connecting rod 42 is fixedly connected to the rectangular frame 41, and the other end is rotatably connected to the adjacent rectangular frame 41. The rotational design allows for a certain rotational angle between the double-sided grooved wheels 2, thereby compensating for the relative clearance generated when the double-sided grooved wheels 2, the upper rail 1, and the lower rail 3 slide. For example, although the groove 22 of the double-sided grooved wheel 2 and the lower rail 3 are slidably connected, there will be a certain gap between the groove 22 and the lower rail 3 in the axial direction of the double-sided grooved wheel 2 due to certain process error. This allows the double-sided grooved wheel 2 to move relatively in the axial direction during rotation. The relative displacement is then compensated by the rotational design of the adjacent rectangular frame 41.

[0042] Specifically, in this embodiment, a long bolt passes through the rectangular frame 41 and the connecting rod 42 and is then connected to a locking nut, so that the connecting rod 42 is fitted onto the long bolt, thereby enabling the connecting rod 42 to rotate relative to each other.

[0043] like Figure 6 As shown, specifically, the lower track 3 includes several arc-shaped lower track segments, and adjacent arc-shaped lower track segments are fastened together by fixed steel clamps 7 on both sides. Since the lower track is narrow, the design of clamping and fixing on both sides makes it easier to open holes in the lower track 3, and the two fixed steel clamps 7 clamping on both sides of the lower track 3 can increase the overall width, thereby increasing the structural strength of the connection.

[0044] Specifically, the upper rail 1 includes several arc-shaped upper rail segments, and adjacent arc-shaped upper rail segments are fastened together by perforated square steel plates 11 at both ends. Since the upper rail 1 uses I-beam rails, which are relatively thick, the design of connecting the ends only requires welding the perforated square steel plates 11 to the ends of the upper rail 1. The width of the perforated square steel plates 11 is greater than the width of the rail groove of the I-beam rail, thus providing operating space for bolt installation. After the bolts pass through the holes in the perforated square steel plates 11, they are threadedly connected to the nuts, thereby realizing the connection of the arc-shaped upper rail segments.

[0045] The working principle and process of this utility model are as follows:

[0046] The design of the inclined abutment surface 61 on the upper rail 1 corresponds to the inclined transition surface 21 on the outer edge of the wheel body 23, so that the two sides of the upper rail 1 are relatively covered by the two sides of the double-sided grooved wheel 2, thus avoiding slippage.

[0047] The width of the lower track 3 corresponds to the width of the groove 22 between the wheel bodies 23. The double-grooved wheel 2 slides into the lower track 3 through the groove 22 between the wheel bodies 23, preventing the lower track 3 from slipping off the double-grooved wheel 2. The combined weight of the turntable, the upper track 1, and the double-grooved wheel 2 acts on the lower track 3, thereby preventing the problem of lifting and maximizing the stability of the sliding between the lower track 3 and the double-grooved wheel 2.

[0048] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
