It is bridged between bearing mounting plates 72 of which two sets are screwed to a screw rod 73 which is bridged between the columns 3a and 3b (see FIG. 6).

Each of the pulley motors 6 has a motor (not shown) serving as a rotational drive source inside the pulleys to rotate the pulleys, and has two belts on its outer surface. Corresponding to No. 8, crowning is formed by laminating rubber-based or synthetic resin-based materials.
This crowning not only prevents the belt from coming off, but also has a soundproof effect. The return pulley 7 is of an independent type corresponding to each line of the belt 8.

The belt 8 relates to the rack member 4 of each layer,
The conveyor belt is wound between the pulley motor 6 and the return pulley 7, and the intermediate portion of the belt has belt sliding surfaces 4c, 4c provided in front and rear of each of the rack members 4 and a pipe shape. The belt receiver 4e and the belt receiver protrusion 4d are in contact with and supported by the upper surfaces thereof. That is, since the pulley motor 6 is rotated counterclockwise in FIG. 5, the tension side of the belt 8 is located on the upper surfaces of the sliding surface 4c and the belt receiver 4e, and the loose side is located on the upper surface of the protrusion 4d. Here, each of the above belts 8 travels inside the rack member 4 via two sets of tension pulleys 61 and 62 provided on the panel member 3d in the end frame EF ₁ as shown in FIG. It is installed in.

As shown in FIGS. 1 and 2, the device of the present invention having the above-described structure has a cage locking member 4g provided on the lower surface of the bottom plate 4a of the rack member 4 for storing small animals. The fact that both the upper surfaces of the cage C are locked and each cage C is supported in a suspended state is similar to the conventional device. The device of the present invention has particular advantages in the following points, which cannot be obtained by conventional products. According to the present invention, the end frames provided at both left and right ends, the main frame in which the pillars are erected in the center of the upper surface of the underframe, and the rack member supported by the cantilever members provided on the pillars of the main frame. Since the rack device for breeding small animals is configured by this, assembly work at the construction site can be performed very easily, and by selecting the number of main frames according to the space at the construction site The rack system has the advantage that it can be easily obtained. Further, in the present invention, a plurality of main frames in which columns are erected vertically at the center of the upper surface of an underframe whose side surface is formed in a substantially inverted concave shape are arranged in parallel so that the columns are located on a straight line in the center. Since the cantilever members are arranged in parallel in the front-rear direction with respect to the columns and arranged in multiple layers, and the rack member is supported between the adjacent cantilever members, Unlike the rack device for small animal breeding, there is no outer frame-shaped support in the front of the rack device, which facilitates breeding management such as cage loading and unloading, and the installation of an automatic feeding device that moves the front of the rack device. Has the real benefit of enabling. Furthermore, in the present invention,
A plurality of main frames in which columns are erected vertically at the center of the upper surface of an underframe whose side surface is formed in a substantially inverted concave shape are arranged in parallel so that the columns are located on a straight line in the center. Since the cantilever members are arranged in multiple layers parallel to each other in the front-rear direction, and the rack member is supported between the adjacent cantilever members, the rack member suspends the breeding cage. Since there are no columns in the area where is provided, it is possible to install a belt conveyor for waste treatment by positioning it below the hanging cage, and also at the front of the rack device. Since there are no columns, the belt conveyor to be installed can be easily attached and detached. Further, in the device of the present invention, the rack member is formed into a groove shape by bending a single steel plate, so that the manufacturing can be performed at low cost by machining, and the seam by welding slides the belt. Since the belt does not appear on the surface, the slipping of the belt is good, and this slipping property is promoted by the spherical protrusion formed on the bottom plate surface of the rack member.
Moreover, since the individual rack members can be easily removed from the beam members of the main frame, labor saving can be achieved when disassembling and cleaning the device. Further, since the belts of the respective layers running between the rack members are driven by the motor pulleys respectively, it is not necessary to separately provide a motor as a drive source of the pulleys as in the conventional product, and therefore the conventional It is possible to solve the problem that the motor as a drive source protrudes from the upper surface of the device like the product, which makes it difficult to install the automatic feeding device. Especially, the motor pulley has two pulleys.
Since the belts are stretched around and crowned with a rubber or synthetic resin material for each belt, the belt is prevented from being displaced and the soundproofing effect is high. Moreover,
In the device of the present invention, since the jet projection pattern of the nozzle for cleaning the belt is a substantially rectangular plane,
Remove the droppings and food waste of breeding animals attached to the belt surface,
There is an advantage that the entire width of the belt can be washed off efficiently. The present invention is as described above, and is extremely useful as a device for attaching and supporting a cage for raising a large number of small animals.
