DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a net-like conveyor belt for livestock breeding equipment which is used as, for example, a floor of a chicken breeding cage or an egg take-out device, and a floor of a rabbit breeding cage.

[0002]

2. Description of the Related Art For example, in a breeding facility for chickens, a floor of a large number of breeding cages is used as an endless transport belt, and while the belt is gradually moved, the feces deposited on the floor are scraped off at a predetermined place and automatically. Cleaning has been done. In addition, the eggs dropped in the breeding basket are rolled and moved on an endless conveyor belt of an egg retrieval device, and are moved to a predetermined place by the conveyor belt.

Hitherto, as an endless belt used for the above-mentioned purpose, a belt-shaped woven fabric of synthetic fibers has been mainly used.

[0004]

However, when a conveyor belt of a synthetic fiber woven fabric is used as a floor of a breeding basket, the accumulated feces may be rubbed off when scraped off with a spatula-like scraper. And there is a problem that it is difficult to remove feces neatly. Also, if the mounting state of the transport belt is disturbed due to foreign matters adhering to the rollers at both ends driving the transport belt, the transport belt gradually shifts left and right, so that the right and left sides of the transport belt contact the side edges of the transport belt. Normally, a guide is provided to contact and suppress this displacement. However, since the synthetic fiber woven fabric conveyor belt has no stiffness, even if it comes into contact with the left and right guides, it is further deflected by bending, and there is a problem that it is difficult to prevent the above deviation. In addition, there is also a problem that, when there is no stiffness, if it is stretched over a long range, it tends to sag.

On the other hand, when a transport belt made of a synthetic fiber woven fabric is used in an egg take-out device, the eggs are transported with the eggs placed on a flat surface, so that the stability of the eggs during transport is poor and the eggs collide with each other. There is a problem that it is easily broken. In addition, when the egg is broken, a large amount of egg yolk or egg white is likely to adhere to the egg. Furthermore, the point that it is difficult to prevent left and right displacement and the point that sag easily occurs are the same as in the case where the floor is used.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and is easy to clean when used as a floor of a breeding cage for livestock, and stably transports eggs when used in an egg retrieval device. It is an object of the present invention to provide a transport belt having excellent stiffness and having a moderate stiffness.

[0007]

According to the present invention, there is provided:
In a net-like conveyor belt for livestock breeding equipment, which is stretched in a belt conveyer and is driven to rotate while being prevented from shifting to the right and left by a guide abutting on a side edge, it is a Russell knitted fabric made of synthetic fibers, The net-shaped base material 1 in which both the warp yarns 3 and the weft yarns 5 are arranged densely at least at both ends as compared with the center portion is immersed in a synthetic resin solution and subjected to a synthetic resin coating. In this method, the warp 3 direction of the base material 1 is joined in the longitudinal direction to form a net-shaped transport belt for livestock breeding equipment (see FIG. 1).

[0008]

In the present invention, the net-shaped substrate 1 provides a tensile strength that can withstand the tension acting when the belt is stretched between rollers as a transport belt. In addition, the synthetic resin coating provides a stiffness as a whole by forming a synthetic resin coating layer 4 on the surface of the net-shaped base material 1.

In particular, in the present invention, the net-shaped base material 1 having square eyes is used because the coated band-shaped body 2 has the same eyes. The square eyes in (1) make the transport belt air-permeable, allow feces and the like to be placed with a small contact area, and furthermore make the eggs hard to roll.

[0010]

FIG. 1 shows an embodiment of the present invention, on which the present invention will be further explained.

In the figure, reference numeral 1 denotes a net-like base material, which is formed by Russell knitting of synthetic fibers and has a square eye.

The synthetic fibers constituting the net-shaped substrate 1 are preferably those having excellent tensile strength, and specific examples include polyester and nylon.

The shape of the eyes is preferably a shape close to a square, but may be a rectangle or another square.

The size of the eyes varies somewhat depending on the application, but when used as a floor for a breeding basket, the length of one side is 5 to 5.
The distance may be set to about 15 mm so that feces and the like do not fall. In addition, when used in an egg retrieval device, the length of one side may be about 10 to 20 mm, and the egg may be set so as to improve sitting.

At least both sides of the net-shaped base material 1
Both the warp yarn 3 and the weft yarn 5 are densely arranged as compared to the center,
Is getting smaller. That is, the warp yarns 3 are densely packed on both sides.
It has high tensile strength. In addition, this network
The substrate 1 is immersed in a synthetic resin solution as described later.
Rarely coated with synthetic resin, both sides are synthetic
The warp yarn 3 and the weft yarn 5 to which the resin is soaked and adhered are densely arranged.
With small eyes and increased rigidity
Part. Therefore, the obtained conveyor belt has a long range.
Not only does it hardly sag when stretched over the enclosure, but also depends on the guide
Prevention of misalignment can be reliably obtained.

When a wide conveyor belt is used, such as when used as a floor for a breeding basket, a small spot similar to the above is formed not only on both sides but also in the middle.
It is preferable to form one to several lines.

This transport belt is obtained by coating the net-like base material 1 as described above with a synthetic resin.
Is formed by a band 2 having a coating layer 4 of a synthetic resin formed on the surface thereof.

The coating is performed by immersing the net-shaped substrate 1 in a solution of a synthetic resin.

As the synthetic resin, for example, vinyl chloride, polyester, polypropylene and the like can be used. After coating, the hardness and adhesion amount after curing are adjusted so that the net-shaped base material 1 has appropriate stiffness and flexibility. Adjust it.

The ends of the strip 2 are joined with the longitudinal direction of the warp 3 of the net-shaped substrate 1 so that the tensile strength can be easily obtained. Can be. Moreover, you may perform by bonding etc.

[0021]

The present invention is as described above, and has the following effects.

(1) Tensile strength with warp yarns 3 dense on both sides
Over a long range
Not only does it not sag easily, but the synthetic resin stains on both sides
The warp yarn 3 and the weft yarn 5 which are stuck and adhered are densely arranged,
The eyes are small and the rigidity of the waist is increased.
Is ensured to prevent misalignment due to the guide.
You .

(2) When used as a floor for breeding cages, since it has ventilation, the dung received on it is easy to dry and the contact area of the dung is small, so that the dung can be easily removed with a spatula-shaped scraping tool. Can be scraped off.

(3) When used in an egg take-out device, the eggs can be stably received by the square eyes, and the eggs can be made less likely to collide with each other during transport, so that cracking of the eggs during transport can be prevented. Even if the egg is broken, it is stitch-shaped, so that the small contact area between the present conveyor belt and the egg and the difficulty in attaching egg white and egg yolk make it difficult for the egg to be received next to be soiled. In addition, since it has ventilation, it is difficult for the open breeding equipment to be blown by the wind, and the wind does not cause the transport belt to be raised and the eggs to drop.
