Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a milk claw for milking in a state where a large number of dairy cows are connected in parallel in a barn.
The present invention relates to a device for conveying a milking device such as a teat cup liner and a milk tube.

[0002]

2. Description of the Related Art As a conventional apparatus for transporting milking equipment, a carriage is hung from a rail provided on the upper part of a barn via a pulley.
One that can be moved freely on the rail (Japanese Patent Publication No. 39-28528)
No.) or a method in which an H-shaped rail is sandwiched by a plurality of rollers and a milking device is suspended on the rollers with a chain or the like (Japanese Patent Publication No. 56-9882), and the like. It was to be conveyed vertically on the cow.

[0003]

However, since the conventional transporting apparatus for milking equipment as described above is a system in which a pulley or a roller slides on a rail, the rail is formed at a right angle without drawing an arc like a corner of a barn. It was not possible to make a curved track, and it was virtually impossible to provide a corner with a small radius or a right-angled corner. Therefore, the conventional one requires a reversal space in the barn in order to bend the rail in the opposite direction. Moreover, in the conventional device,
Since it is not possible to provide a right-angled corner, the track is vertically transported over the cow's body, so it is necessary to lift the milking equipment to a predetermined height so that it does not collide with the cow. There is the inconvenience of heavy labor. Therefore, the present invention has been made in view of the above drawbacks of the prior art, and an object of the present invention is to provide one that can be bent at a right angle without drawing an arc and does not require lifting of a milking instrument.

[0004]

[Means for Solving the Problems] That is, according to the present invention, a cow bed for connecting a plurality of cows in parallel and a cow house provided with a passage at the front or rear of the connected cows have a central longitudinal direction. A track installed on the passage and the cow bed while providing guide grooves at predetermined intervals, a sliding body slidably mounted on the track, and a hanger portion suspended from a substantially central lower part of the sliding body. The object of the present invention is achieved by a delivery device for a milking device including a milking device mounted on the hanger portion. A universal joint should be connected in the middle of the hanger.

[0005]

In the device according to the present invention, a track having straight, L-shaped and T-shaped corners is provided on the passage and the cow bed, and the sliding body is slidably mounted on the track.
Therefore, the milking equipment is suspended on the hanger part that is hung at the lower center of the slide body and moved by sliding the slide body along the track. At the L-shaped or T-shaped corner, the guide groove itself is also L-shaped. Or, because it is formed in a T-shape, it is possible to change the direction of the milking equipment by 90 ° by moving the hanger along the groove of the L-shape or T-shape, and when it is located beside the cow body. Then, remove the teat cup unit, milk claw, etc. and attach the unit to the breast for milking. After the milking is completed, remove the unit from the breast and transport it to the hanger part, and again from the L-shaped or T-shaped corner to make a straight track. Move along. As described above, the hanger portion can freely change its direction along the guide groove of the track.

[0006]

The present invention will be described in detail below with reference to the illustrated embodiments. Fig. 1 is a vertical cross-sectional view of the inside of the barn, showing the passage 1
The cattle beds 2 are provided separately from each other, and the stalls 3 are installed in parallel on the cattle beds 2 so that the cattle are connected in two rows. The angle members 4 and 4 (uniformly) in a line symmetry at predetermined intervals
A straight main track A is installed via rail support fittings 14 so that the sub track B is installed perpendicularly to the direction of the cow bed from the main track A via a cross, T-shape or L-shape corner. Further, in the present embodiment, the cross or T
The branch orbit C is installed via the corner. The sub-trajectory B is preferably installed on the cow bed 2 between cows, not on the cow body in the stall (FIG. 7).

A slide body S is placed on the tracks A, B and C. In this embodiment, the slide body S is a disc 6 and a disc 6 of the disc 6 as shown in FIGS. A bolt 7 inserted into a hole provided at the center, a cylindrical collar 8 having a diameter smaller than the distance between the guide grooves 5 covering the root of the bolt 7, a nut 9 for holding the collar 8, and a disc 6 And six ball rollers (ball bearings) 12 mounted on the concentric circles at equal intervals with bolts or the like. A hanger portion H is mounted below the sliding body S, and the hanger portion H has a ring-shaped hook 10 having a partial cutout screwed into an end portion of the nut 9 and the hook 10. It comprises a ring 16 connected to the rod 16 and a rod 18 rotatably supporting the ring 16. By thus connecting the rod member 18 with the hook 10 and the ring 16, the rod seat 18 functions as a universal joint that swings in the front-back and left-right directions in the drawing.

Further, as shown in FIG. 5, the rail support fitting 14 and the angle members 14, 14 forming the tracks A, B, C are joined by a fixing member 14a having a fixing hole in parallel with the angle member 14. It is fixed with bolts and nuts through the holes drilled in the angle member 14 at predetermined intervals.

Next, FIG. 6 shows a second embodiment of the sliding member S, which is a solid synthetic resin (tetrafluoroethylene is preferable) having a cylindrical shape having a hole in the center and a small friction coefficient. A sliding member 20 consisting of, a disc 22 having a hole in the center mounted on the flat upper portion of the sliding member 20 with a bolt, a bolt 7 inserted into the hole of the disc 22, and the bolt 7 And a nut 9 that holds the collar 8 between them. In this embodiment, the lower part of the sliding member 20 is also made flat, but the present invention is not limited to this, and a predetermined distance from the center of the sliding member 20 as shown in another embodiment of FIG. However, the extreme value of the curved surface may be located there, and in such a case, the frictional force can be reduced by making line contact with the angle members 4 and 4 forming the track.

Next, FIG. 7 is a plan view showing a state in which a main track A, a sub-track B, and a branch track C are installed. The main track A is installed on the central passage 1, and the cows are fed from the track A. The sub-trajectory B is branched toward the stall constituting the partition of the cow installed on the floor 2, and the branch trajectories C are branched from the sub-trajectory B toward the cow body. Therefore, the sub-trajectory B may be branched every two heads. As a result, the branch points of the trajectories A and B are L-shaped, T-shaped, or cross-shaped.

The hanger portion H shown in FIGS.
8 shows another embodiment of the universal joint in FIG. 8, and the one shown in FIG. 8 is swingably supported by shafts 24 and 25 which are perpendicular to each other at two places in the middle of the bar. Further, the one shown in FIG. 9 is one in which two rods are joined by a ball joint 26 having a ball joint.

FIGS. 10 and 11 show an embodiment showing the shape of the guide groove 5 at the T-shaped branch portion of the tracks A, B and C, which is mainly used for the sliding body S made of sliding members. Is preferred. That is, when the branch point is formed in an L-shape, a T-shape, or a cross shape, if the guide groove 5 does not have a margin, the corner tends to be hard even if the direction can be changed to an acute angle. Therefore, the radiuses r and R are provided at the corners to widen the diameter of the guide groove 5 so that the direction change to the branch direction can be performed more smoothly. The one shown in FIG. 10 is configured with a radius having a small diameter, and the one shown in FIG. 11 is configured with a radius having a large diameter. Of course, it may be formed in a tapered shape instead of the round shape.

The track on which the sliding body S is mounted is constituted by pipe members 28, 28 instead of the angle members 4, 4.
The pipes 28, 28 are installed so that the guide grooves 5 can be formed at predetermined intervals, and a slide body S composed of a slide member 20 is placed on the track and conveyed. In the case of this embodiment, the contact between the collar 8 and the pipe members 28, 28 is point contact, and the contact with the sliding member 20 having a flat bottom is line contact. Further, in the case where the bottom portion of the sliding member 20 is formed of a curved surface, the sliding member 20 and the pipe members 28, 28 come into contact with each other at four points, and the frictional force becomes very small.

As described above, in the transporting apparatus according to the present invention, the milking equipment is hung on the hanger portion H of the transporting apparatus and moved while sliding on the straight main track A to be formed on the cow side to be milked. The turning point is changed to the sub orbit B. Next, the sub track B is slidably moved to
From the cross-branch point or the T-branch point to the branch orbit C branched to the side of the cow to be milked, the sliding body S is further moved and stopped at a predetermined point, and the milking equipment is lowered from the hanger part. Terminate milking by connecting a vacuum tube or milk tube to the pipeline. After the milking is completed, the vacuum tube or milk tube removed from the pipeline and the milking device removed from the cow's udder are hung on the hanger portion, and then the sliding body S is slid on the branch orbit C to move the sub orbit B. Move to the branch point, move across the sub-orbit B to the branch orbit C on the opposite side, milk the adjacent cow as described above, and return to the main orbit A via the branch orbit C and the sub-orbit B. The main track A is again slid on the track A to the sub-track B where the next milking cow is located.

A guide groove 5 is formed on each of the tracks A, B and C according to this embodiment, and the guide groove 5 is formed in the slide member S.
Since the collar 8 moves while abutting and is formed so that the corner portion is rounded so as to lead to the sub-orbit B or the branch orbit C at each branch point, the collar 8 can be smoothly guided. The hanger portion H is connected to the sliding body S, but when the worker holds the lower portion of the transport device and pulls or pushes, the direction of the force is not only horizontal but oblique to the track. There is also a direction, but in this embodiment,
Since the hanger portion H is connected by the universal joint, unnecessary force is reduced by the sliding body S and the bar member 18, so that the sliding body S and the rod member 18 do not act as a brake when sliding.

In the present embodiment, the angle member is constructed so that a predetermined groove can be formed through the support fitting, and no special treatment is applied to the surface of the angle member, but the present invention is to slide on the raceway. Therefore, a resin having a small friction coefficient may be attached to the sliding surface of the angle member. Tetrafluoroethylene is preferable as the resin, but in this case, it is preferable to bake the resin on the surface of the angle material or apply a coating material containing tetrafluoroethylene.

[0017]

[Effect] As described above, the milking device transporting device according to the present invention can change the direction substantially at right angles without drawing an arc unlike the conventional device, so that the cowshed space can be effectively utilized. At the same time, the transport distance can be shortened. In addition, unlike the conventional device, the transportation route does not cross the cow, but is configured to pass on the passage and between the cows, so that the milking device can be hung on the hanger part of the transportation device. Is low and labor is low.
