Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pig feeder suitable for feeding 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 immediately above the feeding mouth, a pig feeder 31 shown in FIG. 5 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 condensing in the shape of a bridge immediately above the feeding port 36, and the bait a is well supplied to the bottom plate 37. is there. 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 mounting work of the diaphragm 35 is troublesome, and the manufacturing cost of the diaphragm 35 is also high, so the manufacturing cost of the pig feeder 31 is also high. . Further, since the pig vibrates the diaphragm 35 frequently, the diaphragm 35 made of leaf spring steel is easily deformed and damaged, and the diaphragm 35 does not operate as expected in a relatively short period of time. In such a case, it had to be replaced.

The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to provide a feeding system with a very simple structure without mounting a special member such as a diaphragm. The purpose of the present invention is to provide a feeder for pig farms, which prevents the feed from aggregating in a bridge shape in the tank and allows the feed to be satisfactorily discharged from the feed opening.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the pig feeder of the present invention is such that the distance between the front wall and the rear wall is gradually increased as it goes from the middle portion to the lower end of the feeding tank, and the lower end portion of the rear wall portion is increased. The gradual decrease in the distance between the front wall and the rear wall with the sloping part as the slope, and the gap between the lower end of the adjusting plate at the lower end of the front wall and the gentle slope of the rear wall as the feeding port. It is characterized by

Here, the adjusting plate may be fixed to the lower end portion of the front wall portion so that the vertical position can be adjusted. The action rod is fixed to the front surface of the adjusting plate and the upper end portion of the feeding tank is attached to the rear surface thereof. Fix the lower end of the support rod suspended vertically from the provided support plate, and insert both ends of the support rod between the abutting plate and the front wall, which are fixed to the lower ends of both sides of the front wall. It may be movable up and down and left and right by a distance.

[0008]

[Action]

 From the middle part to the bottom part of the feeding tank, the distance between the front wall and the rear wall is gradually increased, so the bait is not compressed so much, and the gently inclined part of the rear wall is Since the weight load is consumed as a force for moving the bait, the bait is not compressed so much, and the bait is hardly aggregated in a bridge shape immediately above the feeding mouth.

Further, by setting the adjusting plate at an appropriate position, the flow rate of the bait discharged from the feeding port can be adjusted, the action rod is fixed to the front surface, and the lower end portion of the support rod is fixed to the back surface. However, in the case of an adjusting plate with both ends inserted between the abutment plate and the front wall, the pig presses the working rod with its nose or mouth, causing the adjusting plate to move irregularly up, down, left and right. By moving it, the flow rate of food discharged from the feeding port can be adjusted by itself.

【Example】

 An embodiment of the pig feeder of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, the pig feeder 1 of the present invention defines a feeding tank 5 from a front wall portion 2, a rear wall portion 3 and a side wall portion 4, and a rear wall below the feeding tank 5. A bottom plate 6 connected to the part 3 is arranged.

The distance between the front wall portion 2 and the rear wall portion 3 is gradually reduced from the upper end portion of the feeding tank 5 toward the middle portion, and gradually increased from the middle portion to the lower end portion of the rear wall portion 3. The lower end is gradually reduced as a gentle slope 3a. Then, a gap between the lower end of the adjusting plate 7 fixed to the lower end of the front wall 2 and the gently inclined part 3a of the rear wall 3 is used as a feeding port 8, and the feeding a is discharged from the feeding port 8 to form a bottom plate. The bait a is supplied to 6.

In the pig feeder 1, the feed a put into the feeding tank 5 is gradually compressed from the upper end portion to the middle portion of the feeding tank 5, but is not so compressed from the middle portion to the lower end portion. The gradual compression is made in the gently inclined portion 3a of the rear wall portion 3. Here, in the gently sloping portion 3a of the rear wall portion 3, the weight load due to the bait a is consumed as a force that causes the bait a to flow along the gently sloping portion 3a. And it won't be that big. Therefore, the bait a hardly aggregates in a bridge shape immediately above the feeding port 8, and the bait a is satisfactorily discharged from the feeding port 8 and supplied to the bottom plate 6.

The adjusting plate 7 is formed with a long hole 7a or the like so that it can be fixed by a bolt 9 or the like so that the vertical position can be freely adjusted. By setting the adjusting plate 7 at an appropriate position, the feeding plate 8 The flow rate of the discharged food a can be adjusted.

The feed tank 10 for pigs shown in FIGS. 3 and 4 has exactly the same configuration of the feed tank 5 and the bottom plate 6 as the feed device 1 for pigs shown in FIGS. 1 and 2, but an adjusting plate 11 is provided. The configuration and the support form of the adjusting plate 11 are different.

The adjustment plate 11 has a plurality of U-shaped action rods 12 fixed to the front surface thereof, and a lower end of a support rod 13 fixed to the back surface thereof. A support plate 14 is suspended over the upper end of the front wall 2 and the upper end of the rear wall 3, and an insertion hole 14a is formed in the support plate 14, and the adjustment bolt 15 is inserted into the insertion hole 14a. The male screw portion 15a is inserted. A female screw portion 13a is formed on the upper end portion of the support rod 13, the male screw portion 15a of the adjusting bolt 15 is screwed into the female screw portion 13a, and the butterfly head 15b is picked up to set the adjusting bolt 15. By rotating the support rod 13, the upper and lower positions of the adjusting plate 11 can be adjusted by moving the supporting rod 13 up and down.

Further, L-shaped contact plates 16 are fixed to both lower end portions of the front wall portion 2, and both ends of the adjusting plate 11 are inserted between the contact plate 16 and the front wall portion 2. Thus, the adjustment plate 11 can be moved vertically and horizontally by a predetermined distance, but cannot be moved forward.

Therefore, the pig presses the action rod 12 with his nose or mouth to move the adjusting plate 11 irregularly up, down, left and right to adjust the flow rate of the feed a discharged from the feeding port 8 by himself. You can do it.

Further, by moving the adjusting plate 11 up and down and left and right irregularly, the supporting rod 13 swings irregularly in the feeding tank 5, so that the bait a is bridged near the feeding opening 8. Can be more effectively prevented from condensing.
