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 linked cows are provided on the passage. A main track provided with a pair of angle members in the central longitudinal direction so as to have guide grooves with line symmetry and predetermined intervals, and a cylindrical sliding body made of a synthetic resin slidably mounted on the track. And a hanger portion mounted on the sliding body by a bolt inserted through a hole formed substantially in the center of the sliding body, a collar that covers the outer circumference of the bolt, and a nut that holds the collar, and the hanger portion. This object is achieved by a delivery device for a milking device, which comprises a mounted milking device. 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 a cylindrical sliding body is slidably made of synthetic resin on the track. It has been placed. Therefore, the milking equipment is hung on the hanger part attached to the lower center of the sliding body to move on the main track by sliding the sliding body along the track, and at the L-shaped or T-shaped corner, the guide groove itself Since it is also formed in L-shape or T-shape, by moving the hanger along the groove of L-shape or T-shape, it is possible to change the direction of the milking equipment by 90 ° and move it, and beside the cow body. At the time of positioning, lower 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 over the hanger part, and again from the L-shaped or T-shaped corner. Move along a straight path. 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 not on the cow body in the stall but on the cow bed 2 between cows (FIG. 5).

Next, FIG. 4 shows an embodiment of the sliding body S, which is made of a synthetic resin (tetrafluoroethylene is preferable) having a cylindrical shape having a hole in the central portion thereof and having a small friction coefficient and being hard. A sliding member 20 and a hole provided in the center of the sliding member 20 on the flat upper portion of the sliding member 20 are mounted by bolts or the like. Disc with a hole in the center (washer) 22
A bolt 7 inserted into the hole of the circular plate 22, a collar 8 for covering the outer periphery of the bolt 7, and a nut 9 for holding the collar 8.
Consists of As shown in the figure, the bolt 7 can slide up and down by the difference in length due to the difference in the thickness of the sliding member 22 and the length of the collar 8. In the present embodiment, the lower part of the sliding member 20 is also made flat, but the present invention is not limited to this, and 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. 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. A ring 16 connected to
It comprises a rod 18 which rotatably supports 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, the rail support fitting 14 and the angle members 14, 14 constituting the tracks A, B, C are coupled with each other by fixing a fixing member 14a having a fixing hole in parallel with the angle member 14, as shown in FIG. It is fixed with bolts and nuts through the holes drilled in the angle member 14 at predetermined intervals.

Next, FIG. 5 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 is shown in FIGS. 6 and 7.
6 shows another embodiment of the universal joint in FIG. 6, in which the rod is oscillatably supported by two shafts 24 and 25 which are perpendicular to each other at two places in the middle of the rod. Further, the one shown in FIG. 7 is one in which two rods are joined by a ball joint 26 having a ball joint.

FIGS. 8 and 9 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. 8 is configured with a radius having a small diameter, and the one shown in FIG. 9 is configured with a radius having a large diameter. Of course, it may be formed in a tapered shape instead of the round shape.

In the case where the bottom portion of the sliding member 20 of FIG. 10 is formed by a curved surface, the sliding member 20 and the angle members 4 and 4 are in line contact with each other, and the frictional force is 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.
The collar 8 moves while abutting and is formed so that the corners are rounded so as to lead to the sub-trajectory B or the branch trajectory C at each branch point, so that the collar 8 is smoothly guided in the desired direction. be able to. Hanger part H is attached to this sliding body S
Is connected, but the direction of the force when the worker pulls or pushes the lower part of the transport device is not only the horizontal direction toward the track but also the oblique direction. Then, since the hanger portion H is connected by the universal joint, an unnecessary force is reduced by the sliding body S and the bar member 18, and the brake does not have to be applied when sliding.

In the present embodiment, the angle member is constructed so that a predetermined groove can be formed through the support fitting, and the surface of the angle member is not subjected to any special treatment, but the present invention makes it slide on the track. 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.

[0016]

[Effect] As described above, the delivery apparatus for a milking device according to the present invention is configured to move by sliding a cylindrical sliding body made of synthetic resin on the track, and a cross that guides the sub-track. Since each corner is rounded at the corners of T, L, and T, it is possible to change the direction without resistance without drawing an arc unlike the conventional one, so the cowshed space is effective. It is possible to shorten the transport distance as well as to be used.
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.
