Description

Feed supply device

Technical Field

The present invention relates to a feed supply device for supplying feed to chickens to a trough disposed along a cage row in a chicken raising facility.

Background

In a facility for raising a plurality of chickens by a plurality of cages, a plurality of cage rows formed by arranging the cages side by side in a horizontal direction are stacked in a plurality of layers. A long trough for receiving chicken feed is horizontally disposed on a side surface of each cage row. In order to supply a feed for chickens to the inside of a trough, a feed supply device that slides inside the trough has been used. A general feed supply device includes: a feed storage part having an inlet opening opened upward; and an opening formed in the lower part of the feed storage part. In such a feed supplying apparatus, feed introduced from a hopper or a nozzle provided above the feed supplying apparatus through an inlet port is accumulated in a feed accumulating portion, and a part of the feed is discharged into a trough from an opening portion.

The feed required by the chickens varies according to the growth process of the chickens. Therefore, the present applicant has also proposed a feed supply device capable of adjusting the size of an opening through which feed is discharged into a trough (see patent document 1).

However, in recent years, among chicken breeders, there has been a penetration of ideas: the chicken which can be freely eaten at any time is unlikely to grow bigger. This is because chickens fed with sufficient feed all the time have a reduced desire to eat after they are full, while chickens fed with insufficient feed have a greedy desire to eat, and therefore the overall food consumption increases and grows larger. Therefore, in order to feed chickens, a feed supply device capable of adjusting the amount of feed supplied to a trough more variously and precisely is required.

Problems to be solved by the invention

In view of the above circumstances, an object of the present invention is to provide a feed supply device capable of adjusting the amount of feed to be supplied to a trough in a versatile and precise manner.

Means for solving the problems

To solve the above problems, the present invention provides a feed supply device

"is a feed supplying device which slides in a trough for feed, characterized in that,

the feed supply device is provided with:

a front wall;

a first back surface wall formed with a first recess at a lower end;

a first lifting plate which is overlapped with the first back wall and is lifted relative to the first back wall;

a second back surface wall spaced apart from the first back surface wall on a side opposite to the side having the front surface wall, and formed at a lower end with a second recess;

a second lifting plate which is overlapped with the second back wall and is lifted relative to the second back wall; and

an inlet opening opened upward for introducing the fodder into the fodder reserving space between the front wall and the first rear wall,

a first opening is formed by exposing the first recess portion as the first lifter plate is raised with respect to the first back surface wall, and

a second opening is formed by exposure of the second recess as the second lifter plate rises with respect to the second back surface wall. "

The feed supply device is used by sliding in the trough under the state that the second back surface wall faces the protective cage. A first concave part and a second concave part are respectively formed at the lower ends of the first back surface wall and the second back surface wall. In addition, a first lifting plate and a second lifting plate are respectively superposed on the first back wall and the second back wall. The space between the front wall and the first rear wall is a feed storage space, and an inlet for introducing feed into the space is opened upward. Therefore, in a state where the first concave portion is covered with the first elevating plate, the feed is introduced into the introduction port from above using the hopper or the nozzle, and the feed can be stored in the feed storage space.

When the first elevating plate is raised with respect to the first back surface wall, the first concave portion covered with the first elevating plate up to this point is exposed, and a first opening is formed between the first concave portion and the inner surface of the trough. Therefore, the feed stored in the feed storage space flows out to the space between the first back surface wall and the second back surface wall through the first opening.

When the second lifter plate is raised with respect to the second back surface wall, a second opening is formed between the second recess and the inner surface of the trough by exposure of the second recess. The feed thus flows out from the space between the first rear wall and the second rear wall via the second opening to the vicinity of the cage. In this state, when the feed supply device is moved, the feed is supplied to a position very close to the cage. The size of the second opening can be changed according to the lifting height of the second lifting plate. Therefore, the amount of the feed supplied to the trough through the second opening at a position close to and easily eaten by the chickens in the cage can be adjusted, and the chickens can be bred in a state of being saturated with the feed.

On the other hand, when the feed supply device is moved in a state where the second opening is closed with the second lifting plate covering the second recess, the feed is supplied to a position in the trough that is farther from the cage than the position of the second back wall. In this way, when only the first opening is opened to supply the feed, the area in the trough where the feed is supplied is smaller than when both the first opening and the second opening are opened to supply the feed. The size of the first opening can be changed according to the lifting height of the first lifting plate. Therefore, by adjusting the amount of feed supplied from the first opening, it is possible to set a limit period during which the chickens are starved of feed, and to raise the chickens in a normal state in which the chickens are neither starved nor fed.

As described above, in the feed supply device of the present invention, the amount of feed can be adjusted at positions having different distances from the cage by opening and closing the second opening and adjusting the sizes of the first opening and the second opening, and thus the feed supply to the trough can be adjusted in a variety of ways and precisely.

The feed supply device of the invention is based on the structure,

the structure may be such that "the space between the first back surface wall and the second back surface wall penetrates in the sliding direction".

Since the space between the front wall and the first back wall is a feed storage space, the space is closed in the sliding direction of the feed supply device. The second back surface wall needs to be spaced apart from the first back surface wall, but a structure in which the first back surface wall and the second back surface wall are connected to each other so that a space therebetween is partially closed can also be conceived. However, if the space between the first back surface wall and the second back surface wall is closed in the sliding direction, if the feed supply device moves in the trough in which the feed remains, the feed is caught by the feed supply device and may overflow from the trough.

In contrast, in the present structure, the space between the first back surface wall and the second back surface wall penetrates in the sliding direction. Thus, even if the feed remains in the trough, the feed flows into the space between the first back surface wall and the second back surface wall as the feed supply device moves, and the possibility of the feed overflowing from the trough can be reduced.

ADVANTAGEOUS EFFECTS OF INVENTION

As described above, according to the present invention, it is possible to provide a feed supply device capable of adjusting the amount of feed to be supplied to a trough in a versatile and precise manner.

Detailed Description

Hereinafter, a feed supply device 1 according to an embodiment of the present invention will be described with reference to the drawings. Hereinafter, a side of the cage 90 on which a person stands is referred to as a front side, a side of the cage 90 is referred to as a rear side, and a direction from the front side to the rear side is referred to as a front-rear direction. The direction orthogonal to the front-rear direction is a direction in which the cage 90 extends, and is a sliding direction of the feed supply device 1.

The feed supply device 1 is used by sliding inside a trough 70 horizontally arranged along a cage row. The trough 70 includes an elongated rectangular bottom surface 73, a front inclined surface 72 extending from an edge on the front surface side of the bottom surface 73 and inclined toward the front surface side, a front standing surface 71 rising upward from the front inclined surface 72, a rear inclined surface 74 extending from an edge on the rear surface side of the bottom surface 73 and inclined toward the rear surface side, and a rear standing surface 75 rising upward from the rear inclined surface 74. The inclination angle of the backward inclined surface 74 is smaller than the inclination angle of the forward inclined surface 72. The height of the upper end of the rear standing surface 75 is lower than the height of the upper end of the front standing surface 71. The chickens raised in the cage 90 extend out of the neck from an opening (not shown) provided in the cage 90 so as to pass over the rear standing surface 75, thereby pecking the feed in the trough 70.

The main structure of the feed supply device 1 includes a front wall 10, a first back wall 20, a first lifting plate 30, a second back wall 40, and a second lifting plate 50.

The front wall 10 is composed of a first front wall 11 and a second front wall 12. The first front wall 11 is an elongated rectangular flat plate. The second front surface wall 12 extends downward from the lower edge of the first front surface wall 11 and is curved with respect to the first front surface wall 11. The inclination angle of the second front surface wall 12 is set to be equal to the inclination angle of the front inclined surface 72 of the trough 70. A shallow recess 19 is formed in the lower middle portion of the second front wall 12.

The first back wall 20 is an elongated flat plate parallel to the first front wall 11. The end face walls 61a extend from both ends of the first back face wall 20 toward the front face wall 10, closing a space between the front face wall 10 and the first back face wall 20. Between the two end face walls 61a, the front face wall 10 and the first back face wall 20 are joined by a plurality of spacers 61 b. The spacer 61b is a flat plate orthogonal to both the front wall 10 and the first back wall 20, and has a front side abutting the front wall 10 and a back side abutting the first back wall 20.

The height of the first back surface wall 20 is set to such a height that the lower edge of the first back surface wall 20 reaches the vicinity of the boundary between the forward inclined surface 72 and the bottom surface 73 when the second front surface wall 12 is brought into contact with the forward inclined surface 72 of the trough 70. The first back surface wall 20 includes a plurality of first recesses 21 on a lower side.

The end face wall 61a and the spacer 61b adjacent thereto are connected at their respective upper end edges by a connecting plate 62. The spacers 61b not connected to the end face wall 61a are also connected to the upper end edges of the adjacent spacers by the connecting plate 62. The connecting plate 62 is a portion to which a hanger 69 for connecting the feed supply device 1 to a device (not shown) for driving the feed supply device 1 to move is attached, and is a portion that reinforces the joining strength of the front surface wall 10 and the first back surface wall 20 together with the spacer 61 b.

The space between the connecting plates 62 adjacent to each other between the front wall 10 and the first back wall 20 is the feed storage space S0 partitioned by the spacer 61b, and has the introduction port 65 opened upward. At the edge of the introduction port 65, an upper edge piece 66 extends short from the upper edge of the first back surface wall 20 while inclining downward. At the tip of the upper edge piece 66, a serrated tooth 67 projects downward, like a saw tooth.

The first lifter plate 30 is an elongated rectangular flat plate that coincides with the first back wall 20. One arm 35 is provided at one end of the first lifter plate 30. The arm 35 is an elongated rectangular flat plate, and is located on an extended surface of the first lifter plate 30. The arm portion 35 extends upward and is inclined outward in the sliding direction. A slide piece 36 extending at right angles toward the front wall 10 is formed at the tip of the arm 35. An arrow-shaped projection 37 facing the back side is provided on the upper surface of the slide piece 36.

A long hole 38 that is long in the extending direction of the arm portion 35 penetrates near the tip of the arm portion 35. Further, a plurality of first long holes 31 that are long in a direction parallel to the long holes 38 are also provided through the first lifter plate 30.

At one end of the first back surface wall 20, a guide plate 25 is provided to protrude from the linking plate 62. The guide plate 25 is a flat plate parallel to the first back surface wall 20, extends upward, and is inclined outward in the sliding direction. The guide plate 25 is parallel to the arm portion 35 in a state where the first rising and lowering plate 30 is overlapped with the first back surface wall 20. One hole 28 is provided through the guide plate 25. The tab 26 extends from the upper edge of the guide plate 25 at a right angle toward the front wall 10 side. A rack portion 27 having a plurality of teeth is formed near the tip of the tab 26. The teeth of the rack portion 27 engage with the projections 37 of the slide piece 36.

A slit 64 that opens outward in the sliding direction is formed along the base of the guide plate 25 in the connecting plate 62 on which the guide plate 25 projects. According to such a configuration, when the first rising and lowering plate 30 is moved so that the arm portion 35 is inserted into the slit 64 in a state where the first rising and lowering plate 30 is overlapped with the first back surface wall 20 (in the arrow direction in fig. 2), the arm portion 35 abuts against the guide plate 25. At the same time, the slider 36 abuts the tab 26 from below, and the hole 28 communicates with the long hole 38.

In a state where the lower edge of the first back wall 20 coincides with the lower edge of the first rising/lowering plate 30, the pin 22 inserted through the upper end of the first long hole 31 of the first rising/lowering plate 30 is fixed to the first back wall 20. In this way, the first elevating plate 30 is integrated with the first back surface wall 20 so as to be able to be elevated. That is, when the arm 35 is brought into contact with the guide plate 25 and the arm 35 is pulled up, the first lifter plate 30 moves the pin 22 relatively in the first long hole 31 and ascends in the oblique direction in which the first long hole 31 extends. The projection 37, which moves together with the arm 35 as the first elevating plate 30 is elevated, engages with any one of the teeth of the rack 27. The hole portion 28 communicates at the lower end of the long hole 38 when the tooth at the highest position in the rack portion 27 is engaged with the projection portion 37, and the hole portion 28 communicates at the upper end of the long hole 38 when the tooth at the lowest position in the rack portion 27 is engaged with the projection portion 37.

The second back surface wall 40 is an elongated flat plate, and a plurality of second recesses 41 are formed along the lower edge. Both ends of the second back surface wall 40 are respectively connected to the front surface wall 10 by connecting rods 60. The length of the connecting rod 60 is set to be a distance of about the width of the bottom of the trough 70 between the first back wall 20 and the second back wall 40. The connecting rod 60 connects the second back wall 40 and the front wall 10 only at their upper portions. Therefore, a space penetrating in the sliding direction is formed between the first back surface wall 20 and the second back surface wall 40.

The height of the second back surface wall 40 at the portion without the second recessed portion 41 is set to such a height that the lower edge of the second back surface wall 40 reaches the vicinity of the boundary between the bottom surface 73 and the backward inclined surface 74 when the second front surface wall 12 is brought into contact with the forward inclined surface 72 of the trough 70. The lower end piece 45 extends from the lower edge of the portion of the second back surface wall 40 where the second recess 41 is not provided, to the back surface side in a short manner. The lower end piece 45 is inclined upward at an angle equal to the inclination angle of the backward inclined surface 74 of the trough 70.

The second lifter plate 50 overlaps the second back surface wall 40 from the back surface side. A plurality of second long holes 51 that are long in the vertical direction are provided through the second elevating plate 50. The second back surface wall 40 is provided with a screw hole 42 at a position communicating with the second long hole 51.

Next, a method of using the feed supply device 1 configured as described above will be described. When the feed supply device 1 supplies the feed into the trough 70, the feed supply device 1 is disposed inside the trough 70. At this time, when the second front wall 12 is brought into contact with the front inclined surface 72 of the trough 70 and the lower end piece 45 is brought into contact with the rear inclined surface 74 of the trough 70, the first back wall 20 and the second back wall 40 are respectively erected so as to be separated from the bottom surface 73 of the trough 70.

The chicken feed is introduced into the inlet 65 of the feed supply device 1 through a hopper or a nozzle, not shown. As shown in fig. 3(a), in a state where the lower end of the first back surface wall 20 is aligned with the lower end of the first elevating plate 30, the space between the front surface wall 10 and the first back surface wall 20 is closed at the lower end because there is no gap between the feed supply device 1 and the trough 70, and the feed is stored in the feed storage space S0.

When the arm 35 is pulled up as described above, the first lifting plate 30 covering the first concave portion 21 of the first back surface wall 20 up to this point is lifted up, whereby the first concave portion 21 is partially exposed as shown in fig. 3(b), and a first opening S1 is formed between the first concave portion and the bottom surface 73 of the trough 70. Thereby, the feed is supplied from the feed reserving space S0 to the bottom surface 73 through the first opening S1. The size of the first opening S1 can be adjusted according to the height of the first elevating plate 30, and the amount of feed supplied from the first opening S1 to the trough 70 can be adjusted.

The height at which the first elevating plate 30 is raised can be adjusted in stages by engagement of any one of the plurality of teeth of the rack portion 27 with the projection portion 37. The adjusted height of the first lifter plate 30 can be fixed by fastening bolts (not shown) passing through the hole portions 28 of the guide plate 25 and the elongated holes 38 of the arm portions 35 with nuts. A rack portion 27 having a plurality of teeth is formed on the adjustment plate 26 inclined with respect to the lifting direction (up-down direction) of the first lifting plate 30. Therefore, the distance by which the first elevating plate 30 is elevated is smaller than the moving distance of the projection 37 that engages with the teeth of the rack portion 27, and the size of the first opening S1 can be finely adjusted.

Further, since the arm portion 35 and the guide plate 25 are inclined outward, interference between the arm portion 35 and the guide plate 25 and a device that moves the feed supply device 1 by being connected to the hanger 69 from above, or a device having a hopper or a nozzle that introduces the feed into the introduction port 65 can be avoided.

As described above, when the fodder is supplied from the first opening S1 onto the trough 70, the lower edge of the second rising/lowering plate 50 is in a state of being aligned with the lower edge of the second back surface wall 40 as shown in fig. 4 (a). In this state, when the feed supply device 1 is moved in the trough 70, the area where the feed is supplied in the trough 70 after the feed supply device 1 is separated is limited to the bottom surface 73. Therefore, by adjusting the size of the first hatch S1 to adjust the amount of feed supplied from the first hatch S1 to the trough 70, it is possible to grow chickens in a normal state without becoming hungry, while providing a limit period for the chickens to eat the feed and to become hungry.

On the other hand, in a state where the feed is supplied from the first opening S1 onto the trough 70, the second elevating plate 50 is raised with respect to the second back surface wall 40 as shown in fig. 4 (b). Then, as the second elevating plate 50 which covers the second concave portion 41 of the second back surface wall 40 is raised up, the second concave portion 41 is partially exposed, and a second opening S2 is formed between the second concave portion 41 and the bottom surface 73 of the trough 70. Therefore, the fodder placed on the bottom surface 73 flows out onto the rear inclined surface 74 via the second opening S2. The size of the second opening S2 can be adjusted according to the height at which the second elevating plate 50 is raised, and the amount of feed flowing out onto the rear inclined surface 74 via the second opening S2 can be adjusted.

The second lifter plate 50 can be fixed to the second back surface wall 40 by fastening bolts 52 inserted through the second elongated holes 51 to the threaded holes 42. The height at which the second elevating plate 50 is raised can be continuously adjusted by the position of the bolt 52 with respect to the second long hole 51.

When the feed supply device 1 is moved in the trough 70 with the second opening S2 open, the feed is supplied not only to the bottom surface 73 but also to the rear inclined surface 74 in the trough 70 after the feed supply device 1 is separated. That is, the feed is supplied to a position which is very close to the chickens in the cage 90 and which is easy to eat. By adjusting the size of the second opening S2, the amount of feed supplied from the second opening S2 to the trough 70 can be adjusted, and chickens can be raised in a state of being saturated with sufficient feed.

As described above, in the feed supply device 1 of the present embodiment, the first opening S1 is opened and closed by the movement of the first elevating plate 30 relative to the first back surface wall 20, and the second opening S2 is opened and closed by the movement of the second elevating plate 50 relative to the second back surface wall 40. Therefore, the feed can be supplied only to the bottom surface 73 of the trough 70 in a state where the second opening S2 is closed, or the feed can be supplied to a position close to the chickens in the cage 90 and easy to eat by opening the second opening S2.

In addition, the size of the first opening S1 can be adjusted by the height at which the first elevating plate 30 is elevated, and the size of the second opening S2 can be adjusted by the height at which the second elevating plate 50 is elevated. Therefore, the amount of the feed can be finely adjusted at each position where the feed is supplied into the trough 70.

A space penetrating in the sliding direction is formed between the first back surface wall 20 and the second back surface wall 40. Therefore, even if the feed supply device 1 is slid in the trough 70 in which a large amount of feed remains, the feed can flow between the first back surface wall 20 and the second back surface wall 40 without being intercepted by the feed supply device 1. Therefore, the possibility that the remaining feed overflows from the trough 70 due to the movement of the feed supply device 1 can be reduced.

The feed supply device 1 of the present embodiment includes an upper edge piece 66 extending in a short direction obliquely downward at the edge of the introduction port 65. Therefore, when the feed is introduced from above through the introduction port 65 and the feed storage space S0 is filled with the feed, a space without the feed is left below the upper edge piece 66. Further, at the tip of the upper edge piece 66, a serrated tooth 67 projects downward. This reduces the possibility of the flowability of the feed being reduced due to the feed being tightly packed in the feed reserving space S0.

The second front wall 12 is a surface that abuts against the front inclined surface 72 of the trough 70, and a shallow recess 19 is formed on the lower side. Therefore, the face closing the lower end of the space between the front face wall 10 and the first back face wall 20 has a step corresponding to the thickness of the second front face wall 12 in the portion serving as the second front face wall 12 and the portion serving as the front inclined face 72. Since the step is provided, when the feed supply device 1 is slid in the trough 70, the feed filled in the feed storage space S0 is vibrated, and therefore, the possibility of the feed being densely filled and the fluidity being lowered can be reduced.

The present invention has been described above by referring to preferred embodiments, but the present invention is not limited to the above embodiments, and various improvements and design changes can be made without departing from the scope of the present invention.

For example, the number of the introduction ports 65, the number of the first concave portions 21, the number of the second concave portions 41, the number of the teeth of the rack portion 27, and the like are not limited to those shown in the drawings.

The shapes of the first recess 21 and the second recess 41 are illustrated as the shapes of the lower ends of the first back surface wall 20 and the second back surface wall 40, respectively, which are cut into a trapezoidal shape. Not limited to this, the first concave portion 21 and the second concave portion 41 may be cut into an arc shape or a triangular shape.
