According to the conveyor belt type conveying apparatus shown in FIG. 4, even a non-uniform mixture such as livestock feed mixed with cut or crushed pasture or straw can be conveyed. The livestock feed can be reliably transported to livestock breeding places. However, when raising a plurality of livestock, it is necessary to provide a plurality of blades 106, and it is necessary to provide a drive system and a control system for the blades 106 for each blade. Maintenance is not easy and the cost is high.
It has also been found that the vibrations of the flat conveyor belt 104 cause the mixed cut or crushed material to be separated during transportation. Therefore, an object of the present invention is a simple structure,
It is an object of the present invention to provide an apparatus for transporting a heterogeneous mixture such as livestock feed mixed with cut or crushed material of pasture or straw, without separating the cut or crushed material.

[0004]

As a result of repeated studies to solve the above-mentioned problems, the present inventor has provided an inclined conveyor belt inclined along one of the inclined surfaces forming the V-shaped inner surface of the transport gutter. By opening an opening for discharging the non-uniform mixture conveyed by the inclined conveyor belt on the other inclined surface of the V-shaped inner surface, livestock feed mixed with cut or crushed grass or straw. Even a heterogeneous mixture of
The present inventors have found that the mixed cut or crushed material can be easily transported to the opening without being separated, and arrived at the present invention.
That is, the present invention provides a V-shaped transport gutter for transporting a heterogeneous mixture of livestock feed or the like mixed with cut or crushed grass or straw, and a slope forming a V-shaped inner surface of the transport gutter. An inclined conveyor belt, which is disposed to be inclined along one of the surfaces and is provided so as to be movable from one end to the other end of the transport gutter in the inclined state, An opening for opening the other inclined surface and extracting the heterogeneous mixture conveyed by the inclined conveyor belt to the outside of the conveying gutter.

In the present invention, the receiving hopper for receiving the heterogeneous mixture conveyed by the inclined conveyor belt is connected to the opening formed on the other inclined surface of the V-shaped inner surface, whereby the receiving hopper is opened. When the non-uniform mixture is full up to this point, the opening is closed by the non-uniform mixture, and the non-uniform mixture cannot be received any more, so that a predetermined amount of the non-uniform mixture can be transported to a predetermined position. In addition, by providing a shutter that opens and closes an opening that draws out the heterogeneous mixture conveyed by the inclined conveyor belt out of the conveying gutter, closing the opening with a shutter prevents the extraction of the heterogeneous mixture from the opening. it can. As the transfer gutter used in the present invention, the included angle of the inclined surface forming the V-shaped inner surface is 70.
By using a transfer gutter of from 100 ° to 100 °, it is possible to balance the power of transporting the heterogeneous mixture with the force of discharging the heterogeneous mixture from the opening.

[0006] In the conveying apparatus of the present invention, the inclined conveyor belt, which is arranged to be inclined along one of the inclined surfaces forming the V-shaped inner surface of the conveying gutter, holds one end of the conveying gutter while maintaining the inclined state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the drawings. FIG. 1 is a schematic diagram illustrating an outline of a feeder for livestock feed used for breeding cattle according to the present invention. In the transport device shown in FIG. 1, feed is supplied to the transport gutter 10 from a supply hopper 12 provided on one end side of the transport gutter 10.
As the feed, there is used a cut or crushed material such as a hay cube obtained by drying and compression-molding grass, straw, and grass. In the vicinity of the outlet of the supply hopper 12, an adjustment plate 14 for adjusting the supply amount of feed to be supplied to the transport gutter 10 is provided. Further, the transport gutter 10 is provided, at the other end, with a drive device 16 for driving an inclined conveyor belt, which will be described later, provided in the transport gutter 10, and the feed conveyed in the middle of the transport gutter 10. Receiving hoppers 18 are connected.

The transfer gutter 10 used in such a transfer device has a V-shaped cross section as shown in FIG. 2, and the transfer gutter 10 is designed to prevent foreign matter such as dust during transfer as much as possible. A ceiling covering the V-shaped inner surface is formed. In this ceiling,
A slit 20 is formed to supply the feed from the supply hopper 12 into the transport gutter 10 and adjust the feed supply amount from the supply hopper 12 by observing the feed state and the like of the feed in the transport gutter 10. As shown in FIG. 3, the inclined surface 10a forming the inner surface of the transfer gutter 10 has
And a driving roller rotated by a driving device 16 in a direction (arrow X direction) from one end to the other end of the transport gutter 10 provided with the supply hopper 12. (Not shown). The inclined conveyor belt 22 passes through the rear side of the inclined surface 10a (outside the transport gutter 10) via the driving roller,
It is endlessly stretched between the driving roller and the driven roller so as to reach the inclined surface 10a via a driven roller (not shown) provided near one end of the transport gutter 10. This is to reduce the size of the transfer device.

[0009] The inclined conveyor belt 22 is provided on the inclined surface 1.
0a allows the rear side to be supported and move, and it is not necessary to use a durable rubber like the flat conveyor belt 104 shown in FIG. 4, and a polyethylene cloth having a thickness of about 2 mm may be used. it can. For this reason, the weight of the inclined conveyor belt 22 can be reduced, and the driving device 16 for driving the inclined conveyor belt 22 can be reduced in size. Like this
As shown in FIG. 3, an opening 24 is formed on the other inclined surface 10b which forms a V-shaped inner surface together with the inclined surface 10a on which the inclined conveyor belt 22 runs, and one end of the receiving hopper 18 is formed in the opening 24. Is connected. At the other end of the receiving hopper 18, a shielding plate 26 is provided so as to be movable in the direction of arrow Y. By moving the shielding plate 24 in a direction to open the other end of the receiving hopper 18, the receiving hopper 18 is moved. The feed conveyed to 18 can be extracted while adjusting the amount according to the growth and health condition of the livestock. Further, a shutter 28 is provided at a connection between one end of the receiving hopper 18 and an opening 24 formed in the inclined surface 10b so as to be slidable in the longitudinal direction (the direction of the arrow W) of the transport gutter 10. The part 24 can be opened and closed. The receiving hopper 18 is, as shown in FIG.
Are provided in the longitudinal direction of the receiving hopper 18.
By opening and closing the shutter 28 provided in each of the above, the receiving hopper 18 that receives the feed can be selected.

In the conveying apparatus shown in FIGS. 1 to 3, an inclined conveyor belt 22 which is arranged to be inclined along an inclined surface 10a forming a V-shaped inner surface of the conveying gutter 10 is maintained in an inclined state. The feed supplied to the transport gutter 10 by moving from one end of the transport gutter 10 to the other end thereof,
While being conveyed by the inclined conveyor belt 22, it is pressed against the inclined surface 10b. Therefore, the feed fed to the opening 24 can be sent to the receiving hopper 18 connected to the opening 24 formed on the inclined surface 10b of the conveying gutter 10. Thus, the inclined conveyor belt 2
By the combination of 2 and the V-shaped inner surface, it is possible to impart a feeding force and a feeding force of the feed from the opening 24 to the feed supplied into the transfer gutter 10. In order to balance the transfer force and the discharge force, the included angle θ (FIG. 2) of the inclined surfaces 10 a and 10 b forming the V-shaped inner surface of the transfer gutter 10 is set to 70 ° to 10
The angle is preferably 0 °, particularly preferably 80 to 90 °. Here, if the included angle θ is less than 70 °, the feeding power of the feed by the inclined conveyor belt 22 increases, but the feed discharging power tends to be insufficient. On the other hand, if the included angle θ exceeds 100 °, the feed force of the feed by the inclined conveyor belt 22 tends to be insufficient, though the feed force of the feed increases.

When the feed stored in the supply hopper 12 is transported by the transport device shown in FIGS. 1 to 3, the feed stored in the supply hopper 12 is transferred from the slit 20 of the transport gutter 10 into the transport gutter 10. To supply. The amount of feed supplied to the transport gutter 10 is adjusted by an adjusting plate 14 provided at the outlet of the supply hopper 12. The feed amount is adjusted so that the feed does not become higher than the upper end of the inclined conveyor belt 22 disposed on the inclined surface 10a. Specifically, the inclined surface 10
In the case where the inclined conveyor belt 22 is provided on substantially the entire surface of the slit a, the feed state of the feed is observed from the slit 20 so that the feed does not exceed the height of the inclined surface 10a (h shown in FIG. 2). The feed amount is adjusted by the adjusting plate 14. The feed supplied from the supply hopper 12 into the transport gutter 10 is pressed by the inclined surface 10 b while being transported by the inclined conveyor belt 22. Therefore, substantially the entire amount of the feed that has reached the first opening 24 is discharged from the opening 24 and received in the receiving hopper 18.

When the first receiving hopper 18 is full, the first opening 24 is blocked by the feed, and the feed is conveyed to the second opening 24 by the inclined conveyor belt 22. And is received by the receiving hopper 18 connected to the opening 24. In this manner, the feed in the supply hopper 12 can be received and the feed can be sequentially distributed to each of the hoppers 18. Each receiving hopper 1
The feed distributed to 8 can be delivered to a feed box or the like by pulling out the shielding plate 26. At this time, the amount of feed to be dispensed can be adjusted by adjusting the withdrawal time of the blocking plate 26 and the like. When it is not necessary to distribute the feed to a specific receiving hopper 18, the shutter 28 provided at the connection portion between the receiving hopper 18 and the opening 24 is closed, so that the receiving hopper 18 is closed.
Is not dispensed.

The feed supplied to the supply hopper 12 is a mixture of cut and crushed material such as grass, straw, hay cubes obtained by drying and compression-molding grass, and vibrates during transportation. For example, the cut or crushed material can be easily separated by the method. However, the feed distributed to the receiving hopper 18 was distributed such that cut and crushed materials were substantially uniformly mixed without being substantially separated. It is presumed that the inclined conveyor belt 22 is moved with its back surface supported by the inclined surface 10a, and the vibration is extremely small.

In order to improve the conveying force of the inclined conveyor belt 22 employed in the conveyor shown in FIGS. 1 to 3, rubber or the like may be applied to the surface of the inclined conveyor belt 22.
As shown in FIG. 3, a stripe pattern may be formed of rubber or the like. In the case where the feed is transported to a predetermined location, as shown in FIG. 1, a single receiving hopper 18 may be provided without providing a plurality of receiving hoppers 18, or an opening 24 may be provided. May not be connected to the receiving hopper 18. This is because the feed can be discharged from the opening 24 to a predetermined location. Furthermore, it may be used as a transport device for transporting litter mixed with straw or sawdust instead of feed, or as a transport device for transporting civil materials mixed with a mixture that is easily separated in civil engineering work. Can also be used. Note that the transport gutter 10 shown in FIG. 2 and FIG. 3 has a ceiling portion on the V-shaped inner surface, but the inclined surface 10a,
A V-shaped transfer gutter composed of only 10b may be used.

[0015]

According to the present invention, it is possible to transport a feed or the like in which cut pieces or crushed pieces which are easily separated are mixed to a predetermined location in a substantially mixed state. In addition, since the back surface of the inclined conveyor belt is supported by the inclined surface of the transport gutter, the weight of the inclined conveyor belt can be reduced, and the transport device can be less expensive than a transport device including a flat conveyor belt.
