Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

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

[0002]

[Prior art]

 A conventional pig feeder is a feeding tank consisting of a front wall, a rear wall and a side wall, where the distance between the front wall and the rear wall is gradually reduced as it goes downward, and the feeding at the lowest end is made narrower. The food was naturally dropped from the mouth, discharged, and supplied to the bottom plate. Therefore, when powdered feed is put into the feeding tank, it is gradually compressed in the feeding tank as it goes downward, and it tends to aggregate in the shape of a bridge in the vicinity of just above the feeding opening. Frequently, it was not discharged.

Therefore, in order to prevent the food from agglomerating in the shape of a bridge in the vicinity of just above the feeding mouth, a pig feeder 31 shown in FIG. 7 has been developed. In this feeder for pigs 31, the distance between the front wall portion 33 and the rear wall portion 34 in the feeding tank 32 is the same as that of the conventional one, but a diaphragm 35 made of leaf spring steel is provided below the front wall portion 33. By vibrating the vibrating plate 35 with the nose or mouth of the pig, the bait a is prevented from aggregating in a bridge shape immediately above the feeding port 36, and the bait a is satisfactorily supplied to the bottom plate portion 37. It is a thing. The vibrating plate 35 is vertically adjustable by an up-and-down position adjusting mechanism 38 so that the flow rate of the bait a discharged from the feeding port 36 can be adjusted.

[0004]

[Problems to be solved by the device]

 However, in the pig feeder 31 described above, the distance between the front wall portion 33 and the rear wall portion 34 is gradually reduced as it goes down as in the conventional case, so that the feed a in the feeding tank 32 goes down gradually. It was impossible to prevent the bait a from condensing in a bridge shape in the middle part of the feeding tank 32. Further, since the feeding port 36 is formed at the lowermost position of the bottom plate portion 37 and is always open, the lowermost portion of the bottom plate portion 37 may be caused when a pig urinates in the bottom plate portion 37. When urine and the like accumulated at the position, the food a near the feeding opening 36 was solidified and the feeding opening 36 was blocked.

The present invention has been made in view of the above conventional problems, and has a simple structure, and can prevent the bait from being aggregated in a bridge shape even in the middle part of the feeding tank. An object of the present invention is to provide a pig feeder that does not block the feeding port even if the pig urinates on the bottom plate.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the pig feeder of the present invention defines a feeding tank with side walls, a front wall, a rear wall and an inclined side wall, and a space between the front wall and the rear wall. Is gradually reduced from the upper end to the middle of the feeding tank, gradually enlarged from the middle to the lower end, and the interval of the inclined side wall is gradually reduced toward the lower end, and the uppermost position of the bottom plate is increased. It is characterized in that a feeding port is formed further above and a feeding valve for opening and closing the feeding port is provided near the feeding port in the feeding tank.

The feeding opening is formed by bending a lower end portion of a front wall portion to form a bent portion, and forming a raised portion on a rear wall portion at a height position corresponding to the bent portion. It is preferable that it is formed by the lower end portion of the portion and the inclined side wall portion.

The feeding valve may be one in which a valve body made of a thin-walled circular tube and an operating member made of the thin-walled circular tube are fixed to each other. Further, a valve body made of a thin circular tube and an operating member made of an L-shaped bent plate may be fixed to each other, or a valve body made of a thin circular tube alone may be used.

Further, in order to be able to appropriately set the upward movement amount of the valve body, a valve movement amount adjusting member including a locking portion and a rod-shaped portion is provided in the feeding tank, and the valve movement amount adjusting member is provided at the locking portion. To a suitable position on the rear wall, insert an insertion hole in the peripheral surface of the valve body of the feeding valve, and insert the lower end of the rod-shaped part of the valve movement amount adjusting member into the insertion hole of the valve body. You may.

The inclined side walls 5 and 6 are provided from the middle portion, the bottom plate portion 7 is provided by connecting from the lower end of the rear wall portion 4, the side wall portions 2 and 2, the front wall portion 3, the rear wall portion 4 and the inclined side wall portion 5 , 6 define a feeding tank 8. Here, the distance between the front wall portion 3 and the rear wall portion 4 gradually decreases from the upper end of the feeding tank 8 toward the middle portion, and gradually increases from the middle portion to the lower end of the feeding tank 8. The intervals of 5 and 6 are gradually reduced toward the lower end.

As shown in FIG. 3, the lower end portion of the front wall portion 3 is bent inward to form a bent portion 3a, and a raised portion is formed on the rear wall portion 4 at a height position corresponding to the bent portion 3a. 4a is formed, and a feeding port 9 is formed by the bent portion 3a, the raised portion 4a, and the lower ends of the inclined side wall portions 5 and 6. Here, the feeding port 9 is formed further above the uppermost position of the bottom plate portion 7.

Inside the feeding tank 8, there is provided a valve movement amount adjusting member 10 comprising a locking portion 10a and a rod-shaped portion 10b. The locking portion 10a has an elliptical annular shape, and the inside thereof is a long hole 11, and the long hole 11 and a mounting hole 12 formed in the upper end portion of the rear wall portion 4 are provided with a thumbscrew 14 through a spacer 13. The valve movement amount adjusting member 10 is fixed to the rear wall portion 4 by inserting it through and tightening it with the nut 15. The rod portion 10b has a bent rod shape, and when the valve movement amount adjusting member 10 is fixed, the lower end thereof is located near the feeding port 9.

A feeding valve 16 for opening and closing the feeding port 9 is provided near the feeding port 9 in the feeding tank 8. As shown in FIG. 4, the feeding valve 16 comprises a valve body 17 made of a short thin circular tube and an action member 18 made of a short thin circular tube fixed to each other by welding or the like. The outer diameter of the valve body 17 is larger than the width of the feeding port 9, and the outer diameter of the acting member 18 is smaller than the width of the feeding port 9. Further, an insertion hole 19 is formed on the peripheral side surface of the valve body 17. As shown in FIG. 3, the valve body 17 is placed inside the feeding tank 8 and the acting member 18 is placed outside the feeding tank 8, and the rod-shaped portion 10 b of the valve movement adjusting member 10 is inserted into the insertion hole 19 of the valve body 17. The lower end portion is inserted, and the outer peripheral surface of the valve body 17 is brought into contact with the bent portion 3a of the front wall portion 3 and the raised portion 4a of the rear wall portion 4.

As shown in FIG. 1, partition plates 20, 20, 20 are erected on one side of the front side of the front wall 3 on both sides of the feeding port 9, and the partition plates 20, 20, 20 are erected. , 20 are feeding compartments 21 and 21 in which one pig can insert the head, and a non-feeding compartment 22 is provided between the side wall portion 2 and the partition plate 20.

The pig feeder 1 of the present invention is constructed as described above. As shown in FIGS. 2 and 3, the outer peripheral surface of the valve body 17 of the feeding valve 16 is always the front wall portion as shown in FIGS. Since the feeding port 9 is closed by contacting the bent portion 3a of 3 and the raised portion 4a of the rear wall portion 4, the feeding a in the feeding tank 8 is not discharged from the feeding port 9.

When a pig thrusts his nose or mouth into the bottom plate portion 7 and presses the action member 18 upward with the nose or mouth, the feeding valve 16 moves upward and the outer peripheral surface of the valve body 17 becomes the front wall portion. Since the feeding port 9 is opened apart from the bent portion 3a of 3 and the raised portion 4a of the rear wall portion 4, the feeding a in the feeding tank 8 is discharged from the feeding port 9 and falls into the bottom plate portion 7. To do.

Here, the feeding valve 16 moves upward until the lower end of the rod-shaped portion 10b of the valve movement amount adjusting member 10 comes into contact with the inner peripheral surface of the valve body 17, that is, by the amount h, and this movement amount h is large. The higher the flow rate of the bait a discharged from the feeding port 9, the greater the Therefore, by tightening the thumbscrew 14 at an appropriate position of the elongated hole 11 of the locking portion 10a, appropriately changing the lower end position of the rod-shaped portion 10b, and appropriately setting the upward movement amount h of the valve body 17, The flow rate of the bait a discharged from the mouth 9 can be adjusted.

As described above, when the pig pushes the action member 18 upward with the nose or mouth to move the feeding valve 16 upward, the valve body 17 moves up and down in the feeding tank 8 to feed the food. The bait a in the middle part of the tank 8 also moves upward or flows downward and is stirred, so that the bait a does not aggregate in a bridge shape even in the middle part of the feeding tank 8.

Further, the distance between the front wall portion 3 and the rear wall portion 4 gradually increases as it goes from the middle portion to the lower end portion of the feeding tank 8, and the feeding port 9 is further extended from the uppermost position of the bottom plate portion 7. Since it is formed on the upper side and the feeding port 9 is normally closed, even if a pig urinates on the bottom plate 7, the feeding port 9 will not be blocked.

Further, the central portion where the head is frequently inserted by the pig is the feeding compartment 21 in which the food a is discharged, and the both side portions where the head is not inserted so frequently are the non-feeding compartment 22 in which the food a is not discharged. The food a in the feeding tank 8 is consumed uniformly and efficiently. In addition, the food a in the non-feeding compartment 22 is sometimes eaten by a pig whose head is inserted, or by cleaning it, it is possible to prevent spoilage and fermentation, prevent waste of the food a, and have good hygiene. Can be held at

In the above embodiment, the feeding valve 16 in which the valve body 17 made of a short thin circular tube and the operating member 18 made of the short thin circular tube are fixed by welding or the like is used. As described above, the feeding valve 23 in which the valve body 24 made of a short thin circular tube and the action member 25 made of an L-shaped bent plate are fixed by welding or the like may be used. Further, as shown in FIG. 6, a feeding valve 26 composed only of a valve body composed of a short thin circular tube may be used. With this feeding valve 26, it is difficult for a pig to press the feeding valve 26 with its nose or mouth, and the upward movement amount h of the feeding valve 26 is small, but the material cost and manufacturing cost are low.

[Effect of device]

 The pig feeder of the present invention is provided with a feeding valve in the feeding tank, and when the pig pushes the nose or mouth upward to move the feeding valve upward, the valve body moves up and down in the feeding tank. As a result, the bait in the middle part of the feeding tank also moves upward or flows downward and is stirred, so that the bait does not aggregate in a bridge shape even in the middle part of the feeding tank.

Further, the distance between the front wall portion and the rear wall portion gradually increases slightly from the middle portion of the feeding tank to the lower end portion thereof, and the feeding port is formed further above the uppermost position of the bottom plate portion. Since the feeding port is normally closed, the feeding port will not be blocked even if a pig urinates on the bottom plate.

Further, since the feeding valve moves upward until the lower end of the valve movement amount adjusting member comes into contact with the inner peripheral surface of the valve body, the lower end position of the valve moving amount adjusting member is appropriately changed to move the valve body upward. By setting the amount appropriately, the flow rate of the food discharged from the feeding port can be adjusted.
