[Technical field to which the device belongs]

 The present invention relates to a pig feeder suitable for feeding pigs.

[0002]

[Prior art]

 In all conventional feeders for pig farming, the lower part of the feeding tank has a gradually smaller diameter or a narrower width.Therefore, when the food is naturally dropped due to gravity, the food at the lower part of the feeding tank tends to form a bridge, There was a risk that food would not be discharged from the feeding port at the bottom of the tank. Also, in the case where a stirrer is provided in the feeding tank to promote the fall of the food, it is possible to prevent the food from forming into a bridge shape to a large extent, but a power source is required and at the same time in the feeding tank. Cleaning of was troublesome.

In order to solve such a problem, as shown in FIG. 5, a suspension shaft having its upper end fixed, inserted through the feeding tank 51, and having its lower end protruding from the lower end opening 51a of the feeding tank 51. There has been proposed a pig feeding device 54 in which 52 is provided, and a feed receiving plate 53 is rotatably attached to the lower end of the suspension shaft 52 (Japanese Utility Model Publication No. 5-39256). According to this pig feeder 54, when the pig presses the food receiving plate 53 with its nose and mouth, the suspension shaft 52 swings and the food receiving plate 53 rotates or swings. The baits therein are not stirred to form a bridge shape, are smoothly discharged from the lower end opening 51a of the feeding tank 51, and fall into the bottom plate 55.

[0004]

[Problems to be solved by the device]

 However, in the pig feeder 54, since the bait plate 53 is a flat disk, the bait adheres to the upper surface of the bait plate 53 in a relatively short period of time, and the bait tank 53 The bait is not smoothly discharged from the lower end opening 51a of 51. Therefore, it was necessary to frequently clean the lower end portions of the food receiving plate 53 and the feeding tank 51. Further, since the bait drops vertically from the lower end opening 51a of the feeding tank 51 to the upper surface of the bait receiving plate 53, it is carried out horizontally by the rotation or swinging of the bait receiving plate 53, so that the bait is fed at the lower end opening 51a. It was difficult to always discharge a certain amount of food satisfactorily because the foodstuffs were easily clogged and fluttered easily. Further, although the pigs are fed in the bottom plate 55, since the pig has the habit of searching for food by its sense of smell, when the bottom plate 55 runs out of food, the nose and mouth are wandered around inside the bottom plate 55. In some cases, the bait receiving plate 53 is pressed and the bait is not discharged from the feeding tank 51 only by pressing. In such cases, efficient feeding could not be performed.

The present invention has been made in view of the above problems, and prevents the food from becoming difficult to be discharged from the lower end opening of the feeding tank in a short period of time, and frequently lowers the lower end of the feeding tank. Eliminates the need to clean food etc., so that the bait can be smoothly discharged from the lower opening of the feeding tank so that a certain amount of food can always be discharged well, and the amount of food discharged is compared. It should be possible to adjust it easily so that it can respond to the fluidity of the feed sufficiently, and in consideration of the habit of the pig, it is possible to always feed efficiently. An object is to provide an inexpensive pig feeder.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the pig feeder of the present invention is provided with a circular tubular feeding tank, and a suspension shaft is oscillated and rotatably suspended at the upper end of the feeding tank to feed the upper end. The feed amount adjusting member in which a disc-shaped member is fixed to the bottom surface of a conical member whose diameter is made smaller than the lower end opening of the tank and gradually expanded downward and whose lower end is slightly larger than the lower end opening of the feeding tank It is characterized in that it is fixed to the lower end portion of the suspension shaft, and the food is supplied to the bottom plate through the gap between the lower end opening of the feeding tank and the inclined peripheral surface of the food amount adjusting member.

Here, the upper end of the suspension shaft is screwed into a support plate installed on the feeding tank, and the suspension shaft is moved up and down to form a gap between the lower end opening of the feeding tank and the inclined peripheral surface of the food amount adjusting member. May be adjustable.

[0008] Furthermore, two contact pins fixed to the suspension shaft at a predetermined angle in the horizontal direction are brought into contact with a retaining pin movably suspended in the support plate in the vertical direction, whereby the bait is rotated at a predetermined angle. The quantity adjusting member may be rotatable.

[0009]

[Embodiment]

 An embodiment of the pig feeder of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the pig feeder 1 of the present invention has a cover 3 fixed to the outer peripheral surface of a bottom plate 2 so that the cover 3 stands upright. The lower part of the feeding tank 6 is fixed to the middle portion by the supporting member 4 and the mounting member 5 to vertically hold the feeding tank 6.

As shown in FIG. 1, the feeding tank 6 is formed by fixing the lower end of a short bowl-shaped tubular body 8 to the upper end of a long circular tubular body 7 by welding or the like. 7a is used as a food outlet, and the upper end opening 8a of the bowl-shaped body 8 is used as a food inlet. Further, the bowl-shaped body 8 is provided with a support plate 11 having insertion holes 9 and 10 formed in the central portion and the intermediate portion.

As shown in FIGS. 1 to 3, the suspension shaft 12 has a male screw portion 12a formed at the upper end and a bait amount adjusting member 13 fixed at the lower end. As shown in FIG. 2, the feed amount adjusting member 13 is a conical member 14 having a disc-shaped member 15 fixed to the bottom surface thereof. The conical member 14 has an upper end portion having a smaller diameter than the lower end opening 7a of the circular tubular body 7 and gradually increasing in diameter downward, and a lower end portion having a slightly larger diameter than the lower end opening 7a of the circular tubular body 7, The member 15 has a larger diameter than the lower end of the conical member 14.

As shown in FIG. 3, the male screw portion 12 a of the suspension shaft 12 is inserted into the insertion hole 9 and the nut 16 is screwed into the suspension shaft 12 so that the suspension shaft 12 can swing and rotate on the support plate 11. It is suspended. An outer peripheral surface of the pipe member 17 having a length substantially equal to the width of the support plate 11 is fixed to one side surface of the nut 16 by welding or the like, and both end portions of the pipe member 17 are bent into the insertion holes 17a. The U-shaped anti-rotation member 18 which is 18a is inserted and these bent portions 18a are positioned on the side surface of the support plate 11 to prevent the nut 16 from freely rotating.

Further, as shown in FIG. 3, a locking pin 19 in which a nut 20 is screwed into a male screw portion 19 a at the upper end is inserted into the insertion hole 10, and an upper outer peripheral surface of the suspension shaft 12 is inserted. The two contact pins 21 and 21 are fixed to each other at a predetermined angle α in the horizontal direction. Therefore, the suspension shaft 12 can be rotated by the angular range α in which the two contact pins 21 and 21 contact the locking pin 19. Here, the predetermined angle α is preferably about 60 °.

Further, as shown in FIG. 1, the water supply pipe 23 is fixed along the front of the water supply tank 6 by the mounting members 22, 22, ... And the water supply port 24 is fixed to the lower end of the water supply pipe 23. Then, water can be supplied into the bottom plate 2.

Since the pig feeder 1 of the present invention is configured as described above, as shown in FIG. 4, the feed a in the feed tank 6 flows along the inclined peripheral surface of the conical member 14. Then, it is smoothly discharged from the gap between the lower end opening 7a of the circular tubular body 7 and the inclined peripheral surface of the conical member 14, and is stacked on the disc-shaped member 15 in an appropriate amount. When a pig thrusts his nose and mouth into the bottom plate 2 and presses his nose and mouth against the disc-shaped member 15 of the food amount adjusting member 13, the suspension shaft 12 swings and the conical member of the food amount adjusting member 13 moves. Since 14 oscillates and rotates back and forth and left and right, the bait a in the feeding tank 6 is discharged more smoothly, and an appropriate amount of bait a is loaded on the disk-shaped member 15 and drops into the bottom tray 2.

Here, the feeding tank 6 is composed of a circular tubular body 7, and the suspension shaft 12 swings, and the conical member 14 of the food amount adjusting member 13 swings and rotates back and forth, right and left, and inside the feeding tank 6. Since the bait a of the above is agitated, the bait a in the feeding tank 6 does not form a bridge shape. Further, since the conical member 14 of the feed amount adjusting member 13 gradually expands in diameter downward, the bait a in the feeding tank 6 flows along the inclined peripheral side surface of the conical member 14 and the circular tubular body 7 It is smoothly discharged from the gap between the lower end opening 7a and the inclined peripheral surface of the conical member 14.

Feeding is performed in the disc-shaped member 15 and the bottom plate 2, and when the feed a on the disc-shaped member 15 decreases, the feed a in the feeding tank 6 is sequentially discharged by its own weight, and the disc-shaped member A proper amount is loaded on the 15. Also, when the bait a runs out on the disc-shaped member 15 or in the bottom plate 2, the pig will look for the bait a on the disc-shaped member 15 with an olfactory sensation. The food a is discharged from the feeding tank 6.

The locking pin 19 is moved upward so that the contact pins 21 and 21 do not contact the locking pin 19, and the bent portion 18 a of the rotation preventing member 18 is rotated upward to move the locking plate 19 to the support plate 11. If the engagement is released, the suspension shaft 12 can be moved up and down by rotating the nut 16, and the gap between the lower end opening 7a of the circular tubular body 7 and the inclined peripheral surface of the conical member 14 can be appropriately set. The supply amount of the bait a to the bottom plate 2 can be adjusted.

Here, due to the pressure of the bait a loaded on the disc-shaped member 15, the discharge flow rate of the bait a from the gap between the lower end opening 7 a of the circular tubular body 7 and the inclined peripheral surface of the conical member 14. Therefore, regardless of the fluidity of the bait a, the discharge amount of the bait a can be adjusted relatively easily without fine adjustment.

In addition, since the pig feeder 1 of the present invention can connect a large number of pig feeders 1 in parallel by connecting the upper end of the bowl-shaped body 8 of the feeding tank 6 to the feed supply pipeline, Suitable for raising head pigs. Moreover, since the water supply pipe 23 is fixed to the front of the food supply tank 6 along the food supply tank 6, the water supply pipe 23 also serves as a partition plate and a reinforcing column, and the pig feeder 1 is extremely simple in structure and inexpensive. It will be

[Effect of device]

 In the pig feeder of the present invention, the feeding tank is made of a circular tubular body, and when the suspension shaft swings, the conical member of the food amount adjusting member swings and rotates back and forth, left and right, and the inside of the feeding tank. Since the food is agitated, the food in the feeding tank does not form a bridge. Then, since the conical member of the feed amount adjusting member gradually expands in diameter downward, the food in the feeding tank flows along the inclined peripheral side surface of the conical member, and the lower end opening of the feeding tank and the conical member It is smoothly discharged from the gap with the inclined peripheral surface. Therefore, the bait is not smoothly discharged within a short period of time, and the bait does not clog at the lower end opening or drop, and a certain amount of bait can always be discharged well. .

Feeding is carried out in the disc-shaped member and the bottom plate, and when the feed on the disc-shaped member is reduced, the feed in the feeding tank is sequentially discharged by its own weight, or on the disc-shaped member or When there is no more food in the bottom dish, the pig will smell and look for the food on the disc-shaped member, and at that time press the disc-shaped member to discharge the food from the feeding tank, so that the feeding is always efficient. Can be done.

[0024] Furthermore, the pressure of the bait loaded on the disk-shaped member causes a small discharge flow rate of the bait from the gap between the lower end opening of the feeding tank and the inclined peripheral surface of the conical member. It is possible to adjust the amount of food discharged relatively easily without having to do so.

Since the pig feeder of the present invention does not require any special member other than the suspension shaft and the feed amount adjusting member, and has an extremely simple structure, it is inexpensive and causes a failure. hard. Also, since a large number of pig feeders can be installed in parallel by connecting the upper end of the feeding tank to the feed supply pipeline, it is suitable for raising a large number of pigs.
