2. Description of the Related Art Conventionally, as a flat-fed poultry feeder, feed that is sequentially dropped from one storage tank is transported in an annular transport pipe by an endless transport means and supplied to chickens (for example, Patent Document 1). ). The transport pipe is provided with a plurality of feed outlets that open downward, and is configured such that the chickens directly feed the feed from a container such as a feeding tray disposed below the feed outlet.
According to this, according to the conveyance direction of a feed, a feeding tray will be filled with a feed in an order from an upstream thing.
JP 2000-316405 A

According to the feeding machine, feed is supplied in stages from the upstream feeding tray, so that a large number of chickens in the poultry house gather together in the upstream feeding tray. Chickens rushing toward the feeding dish will be hurt each other, resulting in a significant drop in the commercial value of the chickens.
In addition, chickens are competing for feed, causing stress for chickens and adversely affecting meat quality. In addition, the difference in the amount of feed eaten causes individual differences in the growth of chickens. When the individual difference is large, it is necessary to divide into groups according to body weight and to carry out a breeding menu for each group, which is troublesome to manage.

  The problem to be solved is that, according to the conventional feeding machine, it is not possible to feed in a wide range at the same time, so it becomes a competition for fodder among chickens, reducing the commercial value of chickens and causing significant individual differences .

The present invention has the following configuration in order to solve the above problems.
That is, the present invention provides a plurality of outlets provided at a predetermined interval in the longitudinal direction, or a feeding pipe having outlets continuously provided in the longitudinal direction, and the feeding pipe, and the longitudinal direction of the feeding pipe. Feeder having transport means for transporting feed in a direction and a supply unit for supplying feed into the feed pipe, the feed from the supply unit into the feed pipe with the discharge opening facing upward And feeding the feed in the longitudinal direction of the feeding pipe, and then using the rotational movement in which the transport means rotates about its central axis , the feeding pipe is in a state where the discharge port opens downward It is inverted, and the feed in the feeding pipe, and discharged by dropping through the outlet, characterized by feeding at a predetermined position in unison.
Thereby, a feeding pipe can be reversed efficiently and can be fed all at once in a wide range.

Further, disposed at one end of the front Symbol conveying means, a torque limiting device for transmitting to the output member via the friction member the rotational movement of the conveying means, is fixed to the other end of the feeding pipe, An output member that has a transport drive unit that rotationally drives the transport unit and a stopper device that prevents rotation when the feeding pipe is reversed, and an output member that rotates in accordance with the rotational movement of the transport unit rotates. In the state where the drive unit rotates together with the feeding pipe and is reversed due to the reaction of being prevented from being blocked, the transfer of the rotational movement of the transport unit is interrupted, and only the transport unit is rotatably provided. It is characterized by. Thereby, a feeding pipe can be reversed efficiently with a simple structure, and a conveyance means can be further rotated continuously.

  Since the feeding machine of the present invention can feed all at once in a wide range, there is no competition for feed among chickens, and the commercial value of chickens is not reduced, and significant individual differences are not caused.

A feeding machine according to the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view illustrating the overall configuration of a feeder 10 according to the present invention. The feeding machine of the present invention is suitable for flat-fed poultry farming.
12 is a feeding trough. The feed trough 12 is formed in a long trough shape that opens at the top so that a plurality of chickens can simultaneously feed the feed in the feed trough 12.
16 is a feeding pipe. The feed pipe 16 is disposed along the feed trough 12 above the feed trough 12 to feed the feed over the longitudinal direction of the feed trough 12, and feed is conveyed inside.

  The feeding pipe 16 and the feeding basket 12 are suspended substantially horizontally by the winch 29 via the support portion 51, and both can be adjusted in height according to the growth of the chicken. One end of the rope 24 is fixed to each of a plurality of portions of the winding pipe 25 disposed in the poultry house so as to extend in the horizontal direction of the winch 29. Then, the hoisting pipe 25 is rotated by driving a hoisting drive unit 26 (for example, an electric motor) fixed to the end of the hoisting pipe 25, so that the hoisting pipe 25 is fixed to the other ends of the ropes 24. The supporting part 51 that is suspended is lifted and lowered.

  50 is a cross-sectional view taken along line AA in FIG. 1 and shows the shape of the support portion 51. In the support portion 51, two support plates 23 having substantially the same shape are arranged in parallel with each other with a gap 52 therebetween. The two support plates 23 are provided with a feed pipe through hole 32 and a feed trough through hole 33, respectively. And is held so as to extend in the horizontal direction.

In addition, three rollers 34 are sandwiched in the gap 52 between the two support plates 23 and are rotatably fixed. The three rollers 34 are disposed around the feeding pipe 16 inserted through the through hole 32 and support the feeding pipe 16 in a rotatable manner.
A cover 27 is fixed so as to surround the feeding pipe 16 from above along the longitudinal direction of the feeding pipe 16 so that the chicken is not damaged by the rotation of the feeding pipe 16.
The chicken can plow the feed 13 in the feeding bowl 12 through the gap between the feeding bowl 12 and the cover 27.

  Reference numeral 17 denotes a supply unit, which is provided above the one end 16 a side of the feeding pipe 16 and feeds the feed into the feeding pipe 16 through the supply port 47. The supply port 47 (see FIG. 10) is formed by cutting out a half of the cross section of the feed pipe 16, and a supply hood 48 for guiding the feed to the supply port 47 is connected to the feed pipe 16. The supply hood 48 is formed so as to gradually expand outward from the feeding pipe 16 side.

  As shown in FIG. 1, the supply unit 17 includes a hopper 11 that has openings at the top and bottom and stores feed, and a supply pipe that is connected to the bottom of the hopper and extends in the horizontal direction. 31. A first opening 31c that opens upward is provided on the one end 31a side of the supply pipe 31, and a second opening 31d that opens downward is provided on the other end 31b side. The first opening 31 c is connected to the opening of the hopper 11, and the second opening 31 d is connected to the dropping cylinder 30. The opening on the lower side of the dropping cylinder 30 is opposed to the opening of the cylinder 18 that is disposed so as to protrude perpendicularly to the central axis 16 c of the feeding pipe 16 on the one end 27 a side of the cover 27. . Further, the lower portion of the cylindrical body 18 faces the opening of the supply hood 48 described above.

  Further, in the supply pipe 31, a supply screw 19, which is a supply conveyance means for conveying feed in the longitudinal direction of the supply pipe 31, is disposed. For example, the supply screw 19 is configured by a screw conveyor in which metal is spirally formed, similar to a screw 14 (conveying means) described later. The supply screw 19 is disposed so that its central axis coincides with the central axis 31e of the supply pipe 31, and is rotated about the central axis 31e by the supply drive unit 20 such as an electric motor.

  According to the supply unit 17 configured as described above, the feed stored in the hopper 11 falls into the supply pipe 31 and is moved from the one end 31a side to the other end 31b side of the supply pipe 31 by the internal supply screw 19. It is conveyed. Then, the feed is introduced into the feeding pipe 16 via the dropping cylinder 30, the cylinder 18 and the falling hood 48. At this time, of course, the feed supply amount to the feed pipe 16 of the supply part 17 does not exceed the conveying capability of the screw 14 in the feed pipe 16 described later.

As shown in FIG. 8 (b), the feeding pipe 16 is provided with a plurality of outlets 15 arranged in a line parallel to the central axis 16 c of the feeding pipe 16 at a required interval. That is, the discharge ports are formed in a line along the longitudinal direction of the feeding pipe. The aforementioned supply port 47 is provided on an extension of the row of the discharge ports 15.
As shown in the cross-sectional view of the feeding pipe 16 in FIG. 8A, the discharge port 15 is preferably formed by cutting out into an arc shape of about 1/6 with respect to the entire circle. The interval between the discharge ports 15 may be equal or different, and the interval may be set in consideration of the size of the chicken.

  Moreover, the screw 14 which is a conveyance means is internally accommodated in the feeding pipe 16 (refer FIG. 1). As the screw 14, for example, there is a screw conveyor in which metal is spirally formed as shown in FIG. 9. Then, the screw 14 arranged with its central axis substantially coincident with the central axis 16c of the feeding pipe 16 is rotated around the central axis 16c by the transport drive unit 21, and feed in the feeding pipe 16 is fed to the feeding pipe 16 In the longitudinal direction (direction parallel to the central axis 16c).

  The transport drive unit 21 is, for example, an electric motor, and is fixed to the flange 35 fixed to the other end 16 b of the feeding pipe 16 by a bolt 36 and integrated with the feeding pipe 16 as shown in FIG. 9. And the drive shaft 37 of the drive part 21 for conveyance penetrates the flange 35, is extended in the feeding pipe 16, is connected with the other end part 14b of the screw 14, and drives the screw 14 to rotate.

  Further, a reversing device 22 for reversing (rotating 180 degrees) the feeding pipe 16 is provided on the one end 16 a side of the feeding pipe 16. The reversing device 22 is configured by arranging a torque limiting device 38 and a stopper device 57 (see FIG. 10) so that the feeding pipe 16 can be reversed using the rotational force of the screw 14 by the transport drive unit 21. Is done.

Next, the configuration of the reversing device 22 will be described in detail (see FIG. 9).
A cylindrical housing 39 with a flange 39 a is fitted into the feeding pipe 16 at one end portion 16 a of the feeding pipe 16 and is fixed with a bolt, and is integrated with the feeding pipe 16.
A shaft 40 penetrates the housing 39 so as to be rotatable about a central axis. Reference numeral 40 c denotes a flange portion of the shaft 40, which serves to prevent the shaft 40 from coming out of the housing 39. One end portion 14a of the screw 14 is connected to the other end portion 40b side of the shaft 40 disposed in the feeding pipe 16, and the central axes of both are coincident. One end portion 40a side of the shaft 40 protrudes outward from the feeding pipe 16 and the housing 39, and a torque limiting device 38 is fitted therein. Specifically, the hub 41, the flange (output member) 42, the plate 43, the disc spring 44, and the adjustment nut 45 are fitted onto the shaft 40 in this order from the other end 40b side of the shaft 40. The hub 41 is fixed to the shaft 40 and can be rotated integrally.

The flange 42 is externally fitted to the small-diameter portion 53 of the hub 41 via a friction material fixed to both surfaces thereof. The flange 42 is connected to the support portion 51 on the one end portion 16a side of the feeding pipe 16 via an L-shaped bolt 46, and its rotation is prevented.
The torque limiting device 38 configured as described above transmits torque between the hub 41 and the flange 42 via the friction material. When an excessive load acts between the hub 41 and the friction material, the hub 41 Slip between the friction material and the torque transmission from the hub 41 to the flange 42 is interrupted. Further, the limit torque value at which torque can be transmitted can be adjusted by the pressing force by tightening the adjusting nut 45.

  Further, as shown in FIGS. 1 and 10, a stopper device 57 including a stopper 54 and two stopper receivers 55a and 55b is provided. A stopper 54 that protrudes radially outward from the outer peripheral surface of the feeding pipe 16 is provided on the one end 16a side of the feeding pipe 16, and two stopper receivers 55a and 55b that receive the stopper 54 are disposed on the one end 16a side. It is arranged so as to protrude from the surface of the support portion 51 made. The stopper receivers 55a and 55b are respectively provided on both sides of the feeding pipe 16, receive the stopper 54 at the upper part thereof, and prevent the feeding pipe 16 from rotating 180 degrees or more.

The inversion mechanism of the feeding pipe 16 by the inversion device 22 will be described with reference to FIGS.
FIG. 10 (b) shows a state in which the plurality of discharge ports 15 and the supply ports 47 are open downward. At this time, the stopper 54 is received by the upper portion of the stopper receiver 55a on the right side of the drawing and is fed. The pipe 16 is prevented from rotating and its posture is maintained. In this state, the screw 14 is rotated forward (rotation in the direction of arrow Y in FIG. 10B) by the transport drive unit 21. The forward rotation of the screw 14 is a rotation direction in which the feed in the feeding pipe 16 is conveyed from the one end portion 16a side to the other end portion 16b side. At this time, since the torque acting between the friction material and the hub 41 is smaller than the limit torque value, the rotational motion of the hub 41 is transmitted and the flange 42 tries to rotate together with the hub 41. However, since the flange 42 is coupled to the support portion 51 and is prevented from rotating, the reaction driving portion 21 rotates (reversely rotates) together with the feeding pipe 16 in the arrow X direction (FIG. 10A). It will be.

  When the feeding pipe 16 rotated in the direction of the arrow X is rotated 180 degrees, the stopper 54 comes into contact with the upper portion of the left stopper receiver 55b and is prevented from further rotation. As a result of the rotation of the conveying drive unit 21 and the flange 42 being prevented, a torque larger than the limit torque value acts between the hub 41 and the friction material, and torque transmission between the hub 41 and the flange 42 is performed. Is blocked, and only the hub 41 rotates forward. That is, as shown in FIG. 10A, the screw 14 continues to rotate normally in the feeding pipe 16 in a state where the supply port 47 and the plurality of discharge ports 15 open upward.

The same operation principle is used when shifting from the state of FIG. 10A to the state of FIG. 10B. In this case, the screw 14 is rotated in the reverse direction (in the direction indicated by the arrow X in FIG. 10) by the transport drive unit 21. Then, due to the reaction, the conveyance drive unit 21 rotates together with the feeding pipe 16 in the arrow Y direction, and the stopper 54 comes into contact with the upper portion of the right stopper receiver 55a to prevent further rotation. And as FIG.10 (b) shows, the screw 14 can continue reverse rotation within the feeding pipe 16 of the state which the supply port 47 and the discharge port 15 open toward the downward direction.
When the feeding pipe 16 is rotated, the three rollers 34 provided on the support portion 51 roll with the rotation, so that the feeding pipe 16 can rotate smoothly.

The feeder 10 having the above configuration is suitable for a feed in which cereals are powdered. The powdered feed is transported well by the screw conveyor and quickly falls from the opening facing downward.
Next, the usage method of the feeder 10 is demonstrated.
First, the conveyance drive unit 21 is started and the screw 14 is rotated in the forward direction so that the feeding pipe 16 is opened with the plurality of discharge ports 15 and the supply ports 47 facing upward. Then, in a state where the screw 14 is rotating in the forward direction, the supply driving unit 20 is started and the supply screw 19 is rotationally driven, and feed is dropped from the supply unit 17 into the feeding pipe 16 and supplied. Then, this state is maintained for a certain time, and the feed is fed by the screw 14 so that the feed supplied from the supply unit 17 spreads from the one end 16 a side to the other end 16 b side of the feed pipe 16.

  When the feed has been transported, the supply drive unit 20 and the transport drive unit 21 are stopped, and the supply screw 19 and the screw 14 are stopped. Then, when the screw 14 is reversely rotated by the transport drive unit 21 and the feeding pipe 16 is rotated (reversed) by 180 degrees, the plurality of discharge ports 15 are opened downward. As a result, the feed in the feeding pipe 16 is discharged from the feeding pipe all at once through the plurality of discharge ports 15 and falls into the feeding bowl 12. Can be distributed. Therefore, chickens are not gathered together at the same time as in the past, and competition between chickens can be prevented, and healthy and quality chickens without trauma or stress can be bred.

Moreover, since conveyance of the feed in the feeding pipe 16 can be performed between feedings, time can be utilized effectively.
Furthermore, according to the feeding machine of the present invention, feeding can be performed simultaneously in a wide range, and the opportunity for chickens to eat the feed becomes even, and no significant individual differences due to differences in the amount of feed eaten occur. Therefore, it is suitable for breeding breeders that lay seed eggs that require fine weight management in order to align sexual maturity.
Further, even after the feeding pipe 16 is reversed, the screw 14 is continuously rotated in the reverse direction (rotation direction in which the feed is conveyed from the other end portion 16b side to the one end portion 16a side), thereby feeding between the discharge ports 15. The feed remaining in the pipe 16 can be surely dropped into the feeding trough 12.

According to the feeding machine, among the plurality of outlets 15, the feed is dropped only from the outlet 15 at a predetermined position, and the feed is distributed only at a predetermined position of the feeding trough, or dropped at every position on the feeding pipe. By adjusting the amount of feed, the amount of feed can be changed depending on the position in the feeding trough.
FIG. 4B shows that the feed screw 19 is rotated at a constant speed to drop the feed from the supply unit 17, and the feed 14 is rotated at a constant speed from the one end 16 a side of the feeding pipe 16 to the other end. The case where the feed pipe 16 is reversed by dropping the feed pipe 16 after being conveyed so as to be distributed substantially uniformly toward the 16b side (see FIG. 4A) is shown. According to this, since a substantially uniform amount of feed falls simultaneously from the plurality of outlets 15 extending from the one end portion 16a side to the other end portion 16b side of the feeding pipe 16, a plurality of substantially uniform amounts of the feed 13 are piled up. Each is made and fed from one end side to the other end side of a feeding rod 12 (not shown).

  On the other hand, as shown in FIG. 2 (b), the feed can be dropped only from the outlet 15 at the center of the feeding pipe 16, and the feed can be distributed only at the center of the feeding rod 12. In this case, as in the case of FIG. 4, the feed screw 19 is rotated at a constant speed while the screw 14 is rotated at a constant speed, and the feed is dropped and supplied for a predetermined time. And after stopping the supply part 17, the screw 14 is rotated as it is for a predetermined time, and feed is conveyed to the center part in the feeding pipe 16. FIG. If the feed pipe 16 is inverted in this state, the feed can be dropped and distributed only in the central portion of the feed trough 12.

Also, as shown in FIG. 3 (b), in order to distribute a larger amount of feed only to the central portion of the feeding trough 12 than in FIG. 2 (b), the supply screw 19 of the supply unit 17 The feed rate from the supply unit 17 is increased by increasing the rotation speed, and the same operation as in FIG.
Furthermore, if the rotational speed of the supply screw 19 is changed midway with respect to the screw 14 rotating at a constant speed, the amount of feed supplied from the supply unit 17 to the feed pipe 16 changes. The amount of feed to be dropped can be adjusted.

  In poultry farming, particularly breeding of breeding chickens, the poultry house may be divided into several hens by partitions, and the chickens may be bred separately according to sex and weight. In this case, the amount of feed and the time for feeding the feed are often changed for each chicken house. However, according to the present invention, as described above, each chicken house uses a single feeder that passes through a plurality of chicken houses. Since feed can be supplied and the amount of feed can be changed, feeding can be easily performed.

The rotation speed, rotation time, and rotation direction of the supply screw 19 and the screw 14 are controlled by controlling the operations of the supply drive unit 20 and the conveyance drive unit 21, respectively. Accordingly, in order to automatically enable the various feeding methods as described above, the operation of the two drive units 20 and 21 is controlled by having a plurality of programs by combining the operations of the two drive units 20 and 21. A control device may be provided.
Furthermore, when an operation panel is provided and a program is selected and the operations of the two drive units 20 and 21 are controlled by a signal transmitted from the operation panel to the control device, the operability is improved.

The embodiment according to the present invention is not limited to this.
For example, the discharge port may be a discharge port continuously provided in the longitudinal direction of the feeding pipe. That is, it is good also as one discharge port extended over the longitudinal direction of a feeding pipe (parallel to the center axis line of a feeding pipe).
Furthermore, the mechanism for reversing the feeding pipe may be manual or a dedicated motor.
FIG. 5 shows a manual feeding machine. Reference numeral 49 shown in FIG. 5B denotes a handle, which is provided on the other end 16 b side of the feeding pipe 16 so as to project radially from the outer peripheral surface of the feeding pipe 16. A collar 58 is externally fitted to one end 40 a of the shaft 40 protruding from the housing 39 and fixed to the shaft 40.
The user can rotate the feeding pipe by 180 degrees by holding the handle 49 integrated with the feeding pipe 16 and rotating it. A stopper device similar to the above may be provided so that the feeding pipe cannot be rotated any more in the state where it is rotated 180 degrees.

FIG. 6 reverses the feeding pipe 16 using an electric motor 56 disposed on the other end 16 b side of the feeding pipe 16. A sprocket 60 is fixed to the output shaft of the electric motor 56, and a sprocket 61 is externally fitted and fixed to the outer periphery on the other end 16b side of the feeding pipe. A collar 58 is externally fitted to one end 40 a of the shaft 40 protruding from the housing 39 and fixed to the shaft 40.
Then, the rotational movement of the output shaft of the electric motor 56 is transmitted from the sprocket 60 to the sprocket 61 via power transmission means such as a roller chain 59, and the feeding pipe 16 rotates. In the state where the feeding pipe 16 is rotated 180 degrees, a stopper device similar to the above is arranged so that it does not rotate any more, and the driving time of the electric motor 56 necessary for reversing the feeding pipe 16 with a timer is set. It is preferable that the rotation of the output shaft is automatically stopped.
Further, as shown in FIG. 7, it is needless to say that the conveyance drive unit 21 and the electric motor 56 may be fixed to the one end portion 16 a side of the feeding pipe 16.
