Abstract

The invention relates to a rotary milking platform that comprises a deck (1) suitable for supporting cows for milking, an I-shaped beam 2 arranged to support the deck and a plurality of rollers or wheels 4 arranged to take at least a substantial amount of the weight of the beam as it moves in a generally rotary fashion; characterised in that each roller is adapted to automatically orient itself to distribute the weight of the beam generally evenly over the roller to avoid or substantially reduce point loading between the beam and the roller in the event that a least part of the beam is not level.

Description

A kind of rotary milking platforms

Technical field

A kind of preferred form of the present invention relates to a kind of rotary milking platforms being applicable to milk cow.But this platform can have other application, and therefore its preferred form or purposes should not be regarded as limitation of the present invention.

Background technology

Rotary dairy industry milking platforms is well-known.They generally include a large discoid table top (deck), and this table top rotates with mobile milk cow by a milking operation.This table top is supported in a circular beam, and this circular beam is supported on again on a series of roller.In use, beam rotates above roller, can cause the wearing and tearing of less desirable beam like this.If beam is out-of-level, then wearing and tearing will be very serious, because usually have sizable point load in this case between beam and roller.Therefore an object of a preferred form of the present invention is at least by certain methods head it off.

Summary of the invention

According to an aspect of the present invention, the rotary milking platforms of the one provided has:

A) table top, is applicable to supporting milk cow to milk;

B) beam, is arranged to support described table top; And

C) multiple roller, is arranged at least most of weight to bear described beam when described beam moves with cardinal principle rotation mode;

It is characterized in that, each roller is suitable for the automatic orientation when described beam out-of-level at least partially and himself is distributed on described roller with the weight general uniform by described beam, thus the point load avoided between described beam and described roller appearance point load or significantly reduce between described beam and described roller.Alternatively, each roller is arranged such that it can with the point load reduced between described beam and described roller or avoid appearance point load between described beam and described roller from lopsidedness to opposite side.

Alternatively, each roller is arranged to tilt in response to the uneven part of the described beam of contact when the unevenness at least partially of described beam, thus keeps the substantially flat between described roller with described beam to contact.

Alternatively, each roller is installed in a bracket, and this bracket can tilt then to make described roller tilt.

Alternatively, each bracket is U-shaped substantially.

Alternatively, each bracket is arranged on a load bearing seat (pedestal).

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

Embodiment

With reference to Fig. 1, this milking platforms has table top 1, and milk cow be may stand on table top 1 when milking.This table top 1 is supported on carrying I type beam, and carrying I type beam is engaged to form an annulus in each end.The sub-fraction of beam (beam) 2 shown in Fig. 2 to Fig. 4, and illustrates beam 2 in Figure 5 completely.Beam 2 is placed on a series of isolated roller.Roller (roller) is blocked by safety guard 3 in fig. 2, but visible with Reference numeral 4 part in Fig. 3, Fig. 4 and Fig. 7.When this milking platforms in use time, beam 2 rotates on roller, then rotary table top with mobile milk cow by a vice-versa.

As shown in Figure 4, beam 2 comprises a wear rib that can be replaced when grinding away (strip) 5.These more structure divisions having helped avoid beam are premature aging due to the friction between beam and roller.

With reference to Fig. 2, Fig. 3 and Fig. 4, when beam 2 rotates on roller 4, each roller 4 rotates around its axis 6.If beam 2 is in or becomes out-of-level or otherwise uneven (uneven), so have significant point load (point loading) between beam and roller.This load can cause the wear rib 5 of beam and/or roller abrasively relatively fast.The premature abrasion of beam or roller can cause expensive maintenance cost and shut-down of milking.Excessive shut-down is especially disadvantageous, because milk cow needs regularly to be milked to reduce the risk that they suffer from mastitis or milk exhaustion usually.For addressing this problem, if roller 4 is arranged so that roller 4 can continuously and automatically tilt from side to opposite side when the uneven part of beam 2 is pressed on roller 4.Such inclination makes one of roller 4 to keep contacting with beam 2, to avoid or at least to reduce point load on a large scale.This illustrates in figure 6, first illustrates that roller 4 is in level in figure 6, then illustrates that roller 4 tilts to a side, then illustrates that roller 4 tilts to the opposing party.

In illustrated the present embodiment, by roller 4 being arranged on the tilt capability that roughly realizes roller 4 in U-shaped bracket (cradle) 7, if but need to adopt other mounting means.Bracket is axle pivotable with axis 8, and axis 8 is at a right angle with the rotation 6 of roller 4.

In addition as shown in Figure 2, Figure 3 and Figure 4, bracket 7, and therefore roller 4, all support by stake shape post 9.Post 9 regulates height by means of bolt 10 and nut 11 telescopically.As best seen in fig. 4, post 9 also supports the cantilever 12 that has maintenance roller (retainer roller) 13, leaves roller 4 to help keeping beam 2 to avoid transverse movement when rotating with table top 1.

Preferably, the bottom of each post 9 is sentenced flat head screw mode at its four angles 14 and is fixed to a plate (not shown), and this plate is arranged in a concrete substrate (not shown).With reference to Fig. 2, by regulating flat head screw 15, or remove a flat head screw 15 in some cases or remove multiple countersink head screw 15 simultaneously, post 9 easily can be adjusted to level.

With reference to Fig. 7, this minor structure is included in when beam 2 rotates and applies oil to lubricate the device of beam 2.This is by realizing with the netted oil pipe of shown in Reference numeral 16.

Although mode is described preferred embodiments more of the present invention by way of example, should be appreciated that and can modify and improve under the prerequisite of the scope not deviating from following claims.
