Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a feed supply device improved so that livestock feed can be smoothly supplied into a feeding pipeline.
[0002]
[Prior art]
Conventionally, as shown in FIG. 7, feed S stored in a feed hopper 104 is supplied into a feed pipeline 103 by a feed supply device 105, and a disk cable 102 built in the feed pipeline 103 is driven by a cable drive device 106. There is known a feed transport device 101 that is driven to continuously transport feed S to a large number of feed devices 107 via a feed pipeline 103.
Here, as shown in FIG. 8, the disk cable 102 has a structure in which disks 102b are fixed to flexible wires 102a at predetermined intervals.
[0003]
As shown in FIG. 9, as the feed supply device 105, one end of an arm 108 is swingably supported on the inner wall 104 a of the feed hopper 104, and a roller 109 is connected to the other end of the arm 108. Is disposed at a feed drop opening 103a of a feeding pipeline 103, and a spring 110 is disposed on an upper surface of an arm 108.
[0004]
According to the feed supply device 105, the roller 109 engages with the disk 102b of the disk cable 102 moving in the direction of the arrow in the feed pipeline 103, and the roller 109 swings in the direction of the arrow. The feed S in the feed hopper 104 is agitated and smoothly dropped and supplied from the feed drop port 103a into the feed pipeline 103 because the spring 110 disposed in the vertical direction expands and contracts.
[0005]
As the cable driving device 106, as shown in FIG. 10, a driving sprocket 112 and a floating pulley 113 are provided in a housing 111, the disk cable 102 is wound around the driving sprocket 112 and the floating pulley 113, and a tension spring is always used. It is known that a pulley 114 pulls a floating pulley 113 via a support member 115 to apply tension to the disk cable 102.
[0006]
According to the cable drive device 106, since the tension is applied to the disk cable 102 by the tension spring 114 at all times, the drive cable 116 is driven by the drive motor 116 so that the disk cable 102 can travel reliably. .
[0007]
[Problems to be solved by the invention]
However, since the lower half of the feed hopper 104 has an inverted conical shape and the lower end has a small diameter, the feed S is apt to agglomerate by its own weight at the lower end, causing a so-called bridge phenomenon. In the feed feeding device 105, the cavity B is easily generated particularly around the spring 110. When the cavity B is formed, the stirring effect of the spring 110 is lost, and the feed S is smoothly dropped and supplied into the feeding pipeline 103. There was a problem that it could not be done.
[0008]
Further, the cable driving device 106 is provided with a driving sprocket 112, a floating pulley 113, a tension spring 114, a support member 115, and the like. The number of components is large, and the assembling work is complicated. The whole was expensive, and the installation work also required labor.
[0009]
Further, although the lower half of the feed hopper 104 is mostly in the shape of an inverted cone, the inside diameter of the lower end varies in various dimensions depending on the manufacturer. Therefore, the feed supply device 105 of various forms and dimensions has to be manufactured correspondingly, and it has to be custom-made and the manufacturing cost has to be increased.
[0010]
The present invention has been made in view of such a conventional problem, and an object of the present invention is to provide a feed pipeline by a feed supply device without causing a bridge phenomenon of the feed S in a feed hopper 104. The feed S can be smoothly dropped and supplied into the inside 103, the number of parts of the cable drive device can be reduced, the assembling work can be simplified, the price of the entire feed transport device 101 can be reduced, and the labor required for the installation work can be reduced. It is an object of the present invention to provide a feed supply device that can reduce the cost, can cope with the feed hopper 104 having various dimensions, can manufacture the feed supply device as a mass-produced product, and can reduce the manufacturing cost.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of a feed supply device of the present invention will be described in detail with reference to the drawings.
[0016]
As shown in FIG. 1, the feed supply device 1 of the present invention is installed at a lower end of a feed hopper 104, and includes a feed supply box 2, a bridge prevention member 3, a rotating shaft 4, and a driving sprocket 5. , A drive motor 6 and the like.
[0017]
The feed supply box 2 is installed at the lower end of the feed hopper 104 by fastening the upper flange 2a of the feed supply box 2 to the lower flange 104b of the feed hopper 104 with bolts and nuts. A drive motor 6 is fixed to the lower surface 2 b of the feed supply box 2, and a drive shaft 6 a protrudes into the feed supply box 2.
[0018]
A drive sprocket 5 is fixed to an intermediate portion of a drive shaft 6a of the drive motor 6, and a disk cable 102 is wound around the drive sprocket 5. The lower end of the rotary support shaft 4 is connected to the distal end of the drive shaft 6a via a connecting pin 7 so as to be vertically movable, and the bridge preventing member 3 is fixed to the upper end of the rotary support shaft 4. is there.
[0019]
As shown in FIGS. 1 to 3, the bridge preventing member 3 is formed by connecting an inverted conical side surface portion 3 b to a peripheral portion of the disk-shaped upper surface portion 3 a and is disposed near a lower end opening in the feed hopper 104. I have. A long hole-shaped feed drop hole 8 whose minor axis is a small diameter is formed in the disc-shaped upper surface portion 3a at appropriate intervals, and the inverted conical side surface portion 3b is substantially parallel to the inner wall surface of the feed hopper 104. is there.
[0020]
A disk-shaped discharge amount adjusting plate 9 is placed on the upper surface of the disk-shaped upper surface portion 3a, and the discharge amount adjusting plate 9 is provided at a position corresponding to the feed drop hole 8 of the disk-shaped upper surface portion 3a. A feed drop hole 10 having the same shape and dimensions is provided. Further, screw shafts 11, 11 are erected at appropriate positions on the disk-shaped upper surface portion 3a, and elongated holes 12, 12 are formed at corresponding positions of the discharge amount adjusting plate 9.
[0021]
Therefore, as shown in FIG. 3 (A), the discharge amount adjusting plate 9 is placed on the upper surface of the disk-shaped upper surface portion 3a, and the screw shafts 11, 11 are inserted through the long holes 12, 12, and the discharge amount adjusting plate 3 is rotated by an appropriate angle, and nuts 13 are screwed onto the screw shafts 11 as shown in FIG. 3 (B), and the discharge amount adjusting plate 9 is fixed at a predetermined position. Can be changed, and the amount of feed S discharged can be adjusted.
[0022]
Since the feed supply device 1 has the above-described configuration, when the drive motor 6 is driven, the drive shaft 6a rotates and the drive sprocket 5 rotates, so that the disk cable 102 can travel.
[0023]
As described above, the feed supply device 1 of the present invention has the cable drive unit integrated therein, and the mechanism corresponding to the cable drive unit includes only the drive sprocket 5 other than the drive motor 6 as a component. In addition, the number of parts is small, the assembling work is easy, the entire feed transporting apparatus 101 is inexpensive, and the installation work requires no labor.
[0024]
When the drive shaft 6a rotates, the rotation support shaft 4 connected to the drive shaft 6a rotates, and the bridge prevention member 3 also rotates.
As a result, the feed S in the vicinity of the disc-shaped upper surface 3a of the bridge prevention member 3 is agitated so that a so-called nest is not formed at the center of the feed hopper 104, and the feed S is perforated on the discharge amount adjusting plate 9. The feed falls through the feed drop hole 10, the feed drop hole 8 formed in the disc-shaped upper surface 3a, and falls into the feed supply box 2.
[0025]
The inverted conical side surface portion 3b is substantially parallel to the inner wall surface of the feed hopper 104, but does not particularly define a predetermined gap therebetween.
However, since the outer diameter of the inverted conical side surface portion 3b and the inner diameter of the inner wall surface of the feed hopper 104 are not manufactured with high accuracy, if the bridge prevention member 3 rotates, first, the gap is relatively wide. Feed S flows into the portion and enters.
[0026]
A centrifugal force due to rotation is applied to the bridge prevention member 3, and the rotation support shaft 4 moves slightly up and down and swings. Therefore, when the bridge prevention member 3 is rotating, the inverted conical side surface is formed. A narrow predetermined gap D is automatically defined between the portion 3b and the inner wall surface of the feed hopper 104.
As described above, since only the narrow gap D is defined between the inverted conical side surface portion 3b and the inner wall surface of the feed hopper 104, no bridge occurs and the feed S is fed from the gap D through the feed supply box. It falls into 2 smoothly.
[0027]
When replenishing the feed S into the feed hopper 104, rainwater or the like may enter and the feed S may be aggregated into a lump. In addition, pebbles or the like may enter the feed hopper 104, or in winter, gloves and masks of an operator may fall and enter the feed hopper 104.
However, as described above, even when the bulk feed and the foreign matter are mixed, the feed fall port is not blocked by the foreign matter as in the related art. That is, most of the bulk feed and foreign matters are accumulated on the upper surface of the bridge prevention member 3, and even if the feed amount is slightly reduced due to the rotation of the bridge prevention member 3, the gap D Is not completely blocked and exhibits a foreign matter removing function like a sieve, so that the feed S can be discharged smoothly without stopping.
[0028]
The feed S that has fallen into the feed supply box 2 from the feed drop hole 8 and the gap D is conveyed in the feed pipeline 103 by the disk cable 102.
[0029]
The discharge amount of the feed S falling into the feed supply box 2 can also be adjusted by changing the height of the inverted conical side surface portion 3b. That is, if the height of the inverted conical side portion 3b is increased, the discharge amount of the feed a increases, and if the height of the inverted conical side portion 3b is reduced, the discharge amount of the feed S decreases.
[0030]
Instead of the feed supply device 1 as described above, a feed supply device 31 as shown in FIG. 4 may be configured. The feed supply device 31 includes a feed supply box 32, a bridge prevention member 33, a rotation support shaft 34, a connection support shaft 35, a joint 36, a support shaft drive device 37, a drive belt 38, pulleys 39 and 40, a drive motor 41, and the like. Consists of

The feed supply box 32 is installed at the lower end of the feed hopper 104 by fastening the upper flange 32a of the feed supply box 32 to the lower flange 104b of the feed hopper 104 with bolts and nuts. The lower half of the feed supply box 32 is formed as an inclined surface 32b, and the lower end thereof is formed with a guide conduit 32c through which the wire cable 102 travels.
[0032]
The drive shaft 37 a of the support shaft drive device 37 and the connection support shaft 35 are connected via a joint 36. A lower end of the rotation support shaft 34 is connected to an upper end of the connection support shaft 35 via a connection pin 42 so as to be vertically movable, and a bridge preventing member 33 is fixed to an upper end of the rotation support shaft 34. It is.
[0033]
The configuration, shape, and the like of the bridge prevention member 33 are the same as those of the bridge prevention member 3, and are disposed near the lower end opening in the feed hopper 102.
The configuration, shape, and the like of the discharge amount adjusting plate 43 placed on the bridge prevention member 33 are the same as those of the discharge amount adjusting plate 9.
[0034]
Since the feed supply device 31 is configured as described above, if the drive motor 41 is driven and the spindle drive device 37 is operated, the drive shaft 37a is rotated, and the connection support shaft 35 and the rotation support shaft 34 are rotated. As a result, the bridge prevention member 33 also rotates.
As a result, the feed S in the vicinity of the disc-shaped upper surface portion 3a of the bridge prevention member 33 is agitated so that a so-called nest is not formed in the center of the feed hopper 104, and the feed S is fed to the feed control plate 43. The falling holes 10 pass through the feed drop holes 8 formed in the disc-shaped upper surface portion 33a and fall into the feed supply box 32.
[0035]
In the same manner as described above, a centrifugal force due to rotation is applied to the bridge prevention member 33, and the rotation support shaft 34 moves slightly up and down and swings, so that when the bridge prevention member 33 is rotating. A narrow predetermined gap D is automatically defined between the inverted conical side surface portion 33b and the inner wall surface of the feed hopper 104.
As described above, since only the narrow gap D is defined between the inverted conical side surface part 33b and the inner wall surface of the feed hopper 104, no bridge occurs and the feed S is fed from the gap D through the feed supply box. It falls into 2 smoothly.
[0036]
Then, the feed S that has fallen into the feed supply box 32 from the feed drop hole 8 and the gap D is conveyed in the feed pipeline 103 by the disk cable 102.

[0039]
When the feed supply devices 1 and 31 are installed in the feed hopper 104, first, as shown in FIG. 6A, the feed is provided at a location having substantially the same diameter as the inverted conical side portion 53 of the installation assistance device 51. The lower end of the hopper 104 is cut off. Then, a fixing insertion hole 104c is formed in the wall surface near the cut portion so as to correspond to the fixing insertion hole 53a of the inverted conical side surface portion 53.
[0040]
Next, as shown in FIG. 6 (B), the inverted conical side surface portion 53 is brought into contact with the wall surface near the cut portion of the feed hopper 104, and the installation assisting device 51 is mounted with bolts and nuts.
