DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a feed transport apparatus for delivering feed from a feed hopper to a plurality of feeders via a pipe by running a disk cable connected endlessly in the pipe.

[0002]

2. Description of the Related Art Conventionally, as a feed transportation device provided with a pipe, a disk cable 102 connected endlessly is inserted into a pipe 103 as shown in FIG.
By pushing the disc cable 102 in the direction of the arrow x by 4, the feed S inserted between the discs 102 b of the disc cable 102 from the feed hopper 105 is transported and delivered to the feeder 107 through the feed drop tube 106. 2. Description of the Related Art A disk cable type feed transport device 101 is known. Here, the disk cable 102 is
As shown in FIG.
02b is fixed at a predetermined interval. In the corner portion 103a where the pipe 103 is bent at a substantially right angle in the vertical or horizontal direction, the conveyance resistance is large, and in order to reduce the conveyance resistance, as shown in FIG. It is arranged.

[0003] As shown in FIG.
A drive sprocket 110 is provided in a housing 109, and a disk cable 102 is
And the drive sprocket 110 is driven by the drive motor 111 so that the disk cable 1
02 is running. Here, the disk cable 10
The floating pulley 113 is disposed in the housing 109 and the disk cable 102 is also wrapped around the floating pulley 113 so that the driving sprocket 110 can be reliably driven by the drive sprocket 110.
The pulley 113 pulls the floating pulley 113 through the support member 115 to apply a tension to the disk cable 102, thereby constituting a disk cable tension applying mechanism 112.

[0004] As shown in FIG. 14, the corner joints 108 are provided with flanges 119a, 119 of covers 119, 120.
The wheel storage portion 123 and the curved tube portion 124 are formed by abutting 0a, 119b, and 120b and tightening with a bolt 121 and a nut 122. Then, the wheel 1 is stored in the wheel storage unit 123 so that a large conveyance resistance force in the corner portion 103a can be reduced.
25 is rotatably supported by a rotating shaft 126,
24, a disk cable 102 in which a disk 102b is fixed at a predetermined interval to a flexible wire 102a is inserted,
The disc 102b is moved while being in contact with the outer peripheral surface of the wheel 125.

[0005]

The conventional driving device 104
In this case, as shown in FIG. 11A, the disk cable 102 moving in the y direction
As shown in FIG. 11B, in order to avoid overlapping between the drive sprocket 1 and the idler pulley 113,
10 is inclined by a predetermined angle. Therefore, unless a strong tension is always applied to the disk cable 102, the disk cable 102 may come off from the drive sprocket 110.

[0006] In addition, the disk cable 1
If the disk cable 102 vibrates greatly even when the disk cable 102 is constantly extended and the tension becomes weak, the disk cable 102 may come off from the drive sprocket 110 in some cases. Further, for some reason, FIG.
2A, a high load may be applied to the disk cable 102, or the disk cable 102 may be disconnected as shown in FIG. Therefore, the disk cable 102 may be disconnected, a high load may be applied,
In order to detect the disconnection, the operating rod 116 is fixed to the support member 115, and limit switches 117 and 118 are arranged at appropriate positions of the housing 109 to constantly monitor. When the disk cable 102 is disconnected, a high load is applied, or the cable is disconnected, the operator immediately re-attaches or adjusts the drive sprocket 110.
Also, since the disk cable 102 is wrapped around the floating pulley 113, the mounting and adjustment work is extremely troublesome.

Further, in the conventional driving device 104, due to its mechanism, the feed S is almost not present inside the pipe 103, that is, the feed hopper 105 which has finished feeding the feed S to all the feeders 107. Must be located immediately before However, the transportation of the feed S does not proceed according to the theory, and the feed S returning from the pipe 103 is gradually
When accumulated in the coil portion of the tension spring 114, the drive sprocket 110, and the shaft portion of the floating pulley 113, the operation of these components is hindered.

Since the feed hopper 105 becomes considerably large and is installed outdoors such as a pig house and a poultry house, the driving device 104 is naturally also installed outdoors, and rainwater or the like enters. The housing 109 was made of stainless steel or covered with a seat cover, but it could not be completely waterproofed, and rainwater or the like entered the drive device 104. , Drive sprocket 110, floating pulley 113, etc.
Feed S became spoiled.

Further, due to its mechanism, only one conventional drive unit 104 can be disposed immediately before the feed hopper 105, and the length of the disk cable 102 to be driven is limited to about 200 m. . Therefore, in order to transport the feed S to a longer distance, another separate feed transport apparatus had to be configured.

On the other hand, in the conventional corner joint 108, as shown in FIG. 14, the disk 102b of the disk cable 102 moving in the z direction is
The transport resistance at the corner 103a is reduced by moving the wheel 125 while rotating the wheel 125 while abutting the outer peripheral surface of the wheel 5. However, when the feed S enters the small wheel storage portion 123 and is compressed, and the frictional resistance of the feed S increases, the wheel 125 does not rotate smoothly.

Thus, the conventional corner joint 1
08 does not significantly reduce the transport resistance at the corner 103a. If the pipe 103 becomes longer and the number of corners 103a increases, the disk cable 10
The load applied to No. 2 was excessive, and there was a risk of disconnection within a short period of time. Also from this point, the pipe 103 cannot be made so long, and the disk cable 102
In case of disconnection, the operator had to immediately re-attach, which was extremely troublesome.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems in the conventional feed transport apparatus. In the drive device, the disk cable can be easily formed without always applying a strong tension to the disk cable. It does not come off from the driving sprocket, and even if the disk cable comes off, if a high load is applied, or if it breaks, it can be easily re-attached and adjusted again, and the returned feed S gradually decreases. Accumulated in the driving device, without obstructing the operation of the driving sprocket, etc., it is not necessary to take special measures for waterproofing against rainwater, etc., and the feed S can be transported over a longer distance. This greatly reduces the load on the disk cable even if the piping is long and the number of corners is large. Karraz, therefore, no possibility that the disk cable is broken in a short period of time, moreover, is to St. provide feed conveying device capable of cost of the entire device is also significantly reduced.
