Abstract

The present invention relates to a kind of rotary milking platforms.The rotary milking platforms have：A) table top 1 is suitble to support milk cow to milk；B) " I " type beam 2, is arranged to supporting bable tops 1；And c) multiple rollers 4, it is arranged to bear at least most of weight of beam 2 when beam 2 is moved with substantially rotation mode；It is characterized in that, each roller 4 be suitable in the case where at least part of beam 2 is not horizontal automatic orientation its own the weight of beam 2 is distributed substantially uniformly throughout on roller 4, to avoid occurring point load between beam 2 and roller 4 or substantially reducing the point load between beam 2 and roller 4.

Description

A kind of rotary milking platforms

Technical field

A kind of preferred form of the present invention is related to a kind of rotary milking platforms suitable for milk cow.However the platform can have There is other application, and therefore its preferred form or purposes are not construed as limitation of the present invention.

Background technology

Rotary dairy industry milking platforms are well-known.They generally include a big discoid table top (deck), which is rotated to milk cow and passes through a milking operation.The table top is supported in a circular beam, the circle Beam is supported on again on a series of rollers.In use, beam rotates above roller, can lead to the abrasion of undesirable beam in this way.Such as Fruit beam is not horizontal, then abrasion will be very serious, because usually there is sizable point to carry between beam and roller in this case Lotus.Therefore a purpose of the preferred form of the present invention is to solve the problems, such as this at least through certain methods.

Invention content

According to an aspect of the present invention, a kind of rotary milking platforms provided have：

A) table top is suitble to support milk cow to milk；

B) beam is arranged to support the table top；And

C) multiple rollers are arranged to bear at least most of heavy of the beam when the beam is moved with substantially rotation mode Amount；

It is characterized in that, each roller be suitable in the case where at least part of the beam is not horizontal automatic orientation its own The weight of the beam is distributed substantially uniformly throughout on the roller, so as to which the appearance point between the beam and the roller be avoided to carry Lotus substantially reduces point load between the beam and the roller.Optionally, each roller is arranged such that it can be from side Opposite side is tilted to reduce the point load between the beam and the roller or avoid the appearance point between the beam and the roller Load.

Optionally, in response to contacting the beam not when each roller is arranged at least part unevenness of the beam Flat and tilt, so as to which the substantially flat between the roller and the beam be kept to contact.

Optionally, each roller is installed in a bracket, which can tilt then to tilt the roller.

Optionally, each bracket is generally U-shaped.

Optionally, each bracket is mounted on a bearing seat (pedestal).

Optionally, the pivot axis of each bracket and the rotation axis of its roller are at a right angle.

Description of the drawings

It will now be described by way of example and with reference to attached drawing to the certain preferred embodiments of the present invention, in attached drawing In：

Specific embodiment

With reference to Fig. 1, which has table top 1, and milk cow may stand in when being milked on table top 1.The table top 1 is propped up On carrying I-beam, carrying I-beam is joined to form an annulus in each end for support.The sub-fraction of beam (beam) 2 exists It is shown in Fig. 2 to Fig. 4, and illustrates beam 2 completely in Figure 5.Beam 2 is placed on a series of rollers spaced apart.Roller in fig. 2 (roller) it is blocked by safety guard 3, but it is partially visible in Fig. 3, Fig. 4 and Fig. 7 with reference numeral 4.When the milking platforms exist When in use, beam 2 rotates on roller, and then rotary table top passes through a milking cycle to move milk cow.

As shown in figure 4, beam 2 includes a wear rib (strip) 5 that can be replaced when grinding away.This is helped avoid More structure divisions of beam premature aging due to the friction between beam and roller.

With reference to Fig. 2, Fig. 3 and Fig. 4, when beam 2 on roller 4 when rotating, each roller 4 is rotated around its axis 6.If beam 2 is in Either become unhorizontal or otherwise uneven (uneven), then significant point load is had between beam and roller (point loading).The load can cause the wear rib 5 of beam and/or roller abrasively relatively fast.The premature abrasion meeting of beam or roller Expensive maintenance cost and milking is caused to be stopped work.Excessive shut-down is especially unfavorable, because milk cow usually requires periodically to be squeezed Milk suffers from mastitis or the risk of milk exhaustion to reduce them.To solve the problems, such as this, if roller 4 is arranged to the injustice of beam 2 Smooth part is pressed in roller 4 when on roller 4 and can continuously and automatically be tilted from a lateral opposite side.Such tilt causes the one of roller 4 A a wide range of holding is contacted with beam 2, to avoid or at least reduce point load.This is illustrated in figure 6, shows roller 4 first in figure 6 It in level, then shows that roller 4 is tilted to a side, then shows that roller 4 is tilted to the opposing party.

In illustrated the present embodiment, realized by the way that roller 4 is mounted in a generally U-shaped bracket (cradle) 7 The tilt capability of roller 4, but if needing that other mounting means can be used.Bracket is pivoted with axis 8 for axis, the rotation of axis 8 and roller 4 Shaft axis 6 is at a right angle.

In addition as shown in Figure 2, Figure 3 and Figure 4, bracket 7, and therefore roller 4 are all supported by stake shape column 9.Column 9 is by means of spiral shell Bolt 10 and nut 11 telescopically adjust height.As best seen in fig. 4, column 9, which also supports one, has maintenance roller (retainer Roller) 13 cantilever 12 leaves roller 4 to assist in keeping beam 2 when being rotated with table top 1 from transverse movement.

Preferably, the bottom of each column 9 is fixed to a plate (not shown) at its four angles 14 in a manner of flat head screw, The plate is arranged in a concrete substrate (not shown).With reference to Fig. 2, by adjusting flat head screw 15 or in some cases It removes a flat head screw 15 or removes multiple countersink head screws 15 simultaneously, column 9 can easily be adjusted to level.

With reference to Fig. 7, which, which is included in when beam 2 rotates, applies oil to lubricate the device of beam 2.This is by with attached drawing mark What a netted oil pipe shown in note 16 was realized.

Although some preferred embodiments of the present invention are described by way of example, it is to be understood that, Without departing substantially from following claims range under the premise of can modify and improve.
