Description

[Detailed Description of the Invention] The present invention relates to a rail joint for supporting a mulch supply truck or a traveling rearing platform.

Round pipes with a circular cross section and various other shapes are known as rails for mulberry breeding stands, but the weight of the breeding stand and mulberry feeding truck acts on the rail connections, causing them to bend. In some cases, the connecting portions were not securely seated on the supports, causing the rails to sway, making it difficult for the mulch truck to move smoothly during use.

The present invention eliminates such drawbacks and has other unique features.The base of the connection part of the joint is thicker than the tip, and the top end of the column of the mulberry breeding stand is placed in a stable state. The seating surface is formed so that the person can sit on it.

This will be explained below along with examples.

The rearing rack can have various configurations, but in the one shown in the figure, the frame member 2 constituting the rearing rack main body 1 has pillars 3 erected on both sides, and the pillars are connected by a horizontal rod 4. are doing.

In the example shown in the figure, the support and the horizontal rod are made of square pipes, and the support is fixed to the end of the horizontal rod by welding, gluing, etc., but the support can be foldably connected to the horizontal rod. In some cases, an appropriate receiving frame is provided at the end of the horizontal rod, and a support is inserted into the support frame so that the support frame and support can be fixed at an appropriate height (as shown).
.

A receiver 5 is provided on the support, and a side rod 6 is inserted into the receiver.

Further, a pin 7 is planted in the horizontal rod of the frame member 2, and on the other hand,
A connecting rod 8 is provided at the end, which is formed flat and has an insertion hole.
With the frame members standing side by side, the insertion holes at the ends of the connecting rods are inserted into the pins to form the rearing stand main body 1.

A mesh body 9 made of metal material, fiber material, or the like knitted over the connecting rod or over the outer connecting rod.
A silkworm seat sheet 10 is further stretched on the top surface of the silkworm seat sheet 10, and the ends of the sheet are hung over the side rods and held by appropriate supporting means 11 to form a silkworm seat.

The joint 12 is integrally molded from a synthetic resin material, but can also be made from a metal material, etc., and has a lateral connection part 14.14 on both sides in which a rail 13 made of a round pipe engages,
A vertical connection part 15 is provided approximately in the middle of the horizontal connection part, extending in a direction intersecting the horizontal connection part, and extending in a direction substantially perpendicular to the horizontal connection part as shown in the figure.

The cross-sectional shape of each connection part is approximately circular, but
It can also be formed into an oval shape, and its thickness gradually becomes thicker inward from the tip, with the central zone being the thickest, and the outer surface has a wall that is inside the rail. It has a protrusion 16 that extends in the longitudinal direction so as to be in contact with it and has a slightly inclined tip.

In addition, in what is shown in the figure, the inner holes of the horizontal connection part and the vertical connection part do not communicate with each other, but they can also communicate with each other.

The intermediate portion 17 between the horizontal connecting portions protrudes from the upper surface of the horizontal connecting portion, so that when the rail is inserted into the connecting portion, the outer surface of the intermediate portion and the outer circumferential surface of the rail are approximately on the same plane. A seating surface 18 is provided on the side facing the vertical connection portion to sit on the upper end of the support of the rearing stand.

The seating surface shown in the figure is formed in a rectangular shape so as to almost cover the upper end of the column, but it can also be formed in a circular or other shape, and the seating surface extends laterally from the middle part. It is also possible to form the support itself to a size corresponding to the upper surface of the support column, and use the lower surface as a seating surface.

The mulberry feeder, second stage rearing stand, and other traveling vehicles 19 have wheels 20, 20 on their lower surfaces.

In the one shown in the figure, the wheels are provided so as to clamp the rail from diagonally above.

By inserting the vertical connection portion of the joint into the support and inserting the rail into the horizontal connection portion, the rails can be successively installed in the longitudinal direction of the rearing table main body (FIGS. 4 and 5).

In addition, at the end of the rail, if you insert the vertical connection part into the rail and one side of the horizontal connection part into the support,
The other lateral connection part can stand up on the end face of the rail and serve as a stopper for the traveling vehicle.

Therefore, even if a large load is applied to the rail when a mulch feeder, breeding stand, etc. is placed on the rail, the connecting portion has a thick base, so it will not bend or bend. It won't break, and it can also be used when driving mulch trucks, etc.
The seating surface of the joint can be stably seated on the upper end of the support column to prevent the rail from moving, thereby allowing the mulch truck to move smoothly.

In addition, the surface of the joint or the whole part is made of elastic rubber,
It may also be made of synthetic resin material or the like, and may be elastically press-fitted.
