Description

Fodder supplying device

Technical Field

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

Background

In a facility for raising a plurality of chickens with a plurality of cages, a plurality of cage rows of cages arranged side by side in a horizontal direction are layered in a plurality of layers. On the side surface of each cage row, a long trough for accommodating chicken feed is arranged in the horizontal direction. In order to supply chicken feed into a trough, a feed supply device that slides inside the trough has been conventionally used. A general feed supply device comprises: a feed storage unit having an inlet opening upward; and an opening formed in the lower portion of the feed storage portion. In such a feed supply device, feed introduced from a hopper or nozzle provided above the feed supply device through an inlet is accumulated in a feed accumulating portion, and a part of the feed is discharged from an opening into a trough.

The feed required for chickens varies according to the growth process of chickens. Accordingly, the present inventors have also proposed a feed supply device capable of adjusting the size of an opening for discharging feed into a trough (see patent document 1).

However, in recent years, between chicken breeders, such ideas have been penetrated: the chickens which can eat freely when they want to eat at any time do not need to grow larger. This is because the desire to eat the chickens who have been fully fed will decline after they have been fully fed, and on the other hand, the chickens who have been fed for a period of time sufficient for feeding will be greedy for eating, so that the overall intake will increase and grow longer. Accordingly, based on such an idea, in order to administer feed to chickens, there is a need for a feed supply device capable of more variously and precisely adjusting the amount of feed to be supplied to a trough.

Problems to be solved by the application

In view of the above-described circumstances, an object of the present application is to provide a feed supply device capable of precisely adjusting the amount of feed to be supplied to a trough in a variety of ways.

Means for solving the problems

In order to solve the above problems, a feed supply device of the present application

"is a feed supply device sliding in a trough for feed, characterized in that,

the feed supply device comprises:

a front face wall;

a first back wall having a first recess formed at a lower end thereof;

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

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

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 upward for introducing feed into the feed storage space between the front wall and the first rear wall,

a first opening is formed by the exposure of the first concave part along with the rising of the first lifting plate relative to the first back surface wall, and

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

The feed supply device is used by sliding in the trough in a state that the second back wall faces the protection cage. First and second concave portions are formed at lower ends of the first and second back walls, respectively. In addition, a first lifting plate and a second lifting plate are respectively overlapped on the first back surface wall and the second back surface 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 lifter plate, the feed is introduced into the inlet from above using the hopper or the nozzle, and the feed can be stored in the feed storage space.

When the first lifter plate is lifted up relative to the first back wall, the first recess covered by the first lifter plate is exposed, and a first opening is formed between the first recess and the inner surface of the trough. Thus, the feed accumulated in the feed accumulation space flows out to the space between the first back surface wall and the second back surface wall via the first opening.

When the second lifter plate is lifted relative to the second back wall, a second opening is formed between the second concave portion and the inner surface of the trough by the exposure of the second concave portion. Thus, feed flows out from the space between the first back wall and the second back 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 height of the second lifting plate. Therefore, the amount of the feed supplied to the trough via 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 cultivated in a fed state in which the feed is sufficiently eaten.

On the other hand, when the feed supply device is moved in a state where the second recess is covered by the second lifter plate and the second opening is closed, feed is supplied to the trough at a position farther from the cage than the position of the second rear wall. In the case where the feed is supplied by opening only the first opening in this way, the area in the trough where the feed is supplied becomes smaller than in the case where the feed is supplied by opening both the first opening and the second opening. The size of the first opening can be changed according to the height of the first lifting plate. Therefore, by adjusting the amount of feed supplied from the first opening, it is possible to set a limited period during which the feed is consumed to make the chicken become starved, or to cultivate the chicken in a normal state in which the chicken is neither starved nor satiated.

As described above, in the present feed supply device, the amount of feed can be adjusted at different positions 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 can be supplied to the trough in a variety of ways and accurately.

In the feed supply device of the present application based on the above-described structure,

the space between the first back surface wall and the second back surface wall may be formed to penetrate in the sliding direction.

The space between the front wall and the first rear wall is a feed storage space, and is thus closed in the sliding direction of the feed supply device. The second back wall needs to be spaced apart from the first back wall, but a structure in which the first back wall and the second back wall are connected to each other so that a space between the two walls is partially closed is also conceivable. However, if the space between the first back wall and the second back wall is closed in the sliding direction, if the feed supply device moves in the trough where feed remains, the feed is intercepted 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 wall and the second back wall in accordance with the movement of the feed supply device, and thus the possibility of the feed overflowing from the trough can be reduced.

ADVANTAGEOUS EFFECTS OF INVENTION

As described above, according to the present application, it is possible to provide a feed supply device capable of precisely adjusting the amount of feed to be supplied to a trough in various ways.

Detailed Description

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

The feed supply device 1 is slidingly used in 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 a front end of the bottom surface 73 and inclined to the front side, a front standing surface 71 rising upward from the front inclined surface 72, a rear inclined surface 74 extending from a rear end of the bottom surface 73 and inclined to the rear side, and a rear standing surface 75 rising upward from the rear inclined surface 74. The inclination angle of the rear inclined surface 74 is smaller than the inclination angle of the front 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 chicken raised in the cage 90 protrudes from an opening (not shown) provided in the cage 90 to the neck so as to pass over the rear standing surface 75, and pecks the feed in the trough 70.

The main structure of the feed supply device 1 comprises 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 constituted by 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 wall 12 extends downward from the lower side of the first front wall 11, and is curved with respect to the first front wall 11. The inclination angle of the second front 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 middle of the lower edge 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 the 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 surface wall 10 and the first back surface wall 20, and the front side edge is in contact with the front surface wall 10 and the back side edge is in contact with the first back surface wall 20.

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

The upper end edges of the end face wall 61a and the spacers 61b adjacent thereto are connected by a connecting plate 62. The spacers 61b not connected to the end face wall 61a are also connected to each other by the connecting plate 62 at the upper end edges of the adjacent spacers. 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 for reinforcing 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 adjacent connecting plates 62 between the front wall 10 and the first back wall 20 is a feed storage space S0 partitioned by a spacer 61b, and has an inlet 65 opened upward. At the edge of the inlet 65, the upper edge piece 66 extends from the upper edge of the first back surface wall 20 to a short extent while being inclined downward. At the end of the upper edge piece 66, a sawtooth-shaped tooth portion 67 protrudes 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 the extension surface of the first lifter plate 30. The arm 35 extends upward and is inclined outward in the sliding direction. A slider 36 extending at right angles toward the front wall 10 is formed at the tip end of the arm 35. An arrow-shaped projection 37 facing the rear surface side is provided on the upper surface of the slider 36.

A long hole 38 long in the extending direction of the arm 35 is provided in the vicinity of the distal end of the arm 35. The first lifter plate 30 is also provided with a plurality of first long holes 31 extending in a direction parallel to the long holes 38.

At one end of the first back wall 20, a guide plate 25 is provided protruding from the web 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 35 in a state where the first lifter plate 30 is overlapped with the first back surface wall 20. The guide plate 25 is provided with a hole 28. The tab 26 extends from the upper edge of the guide plate 25 at right angles toward the front wall 10 side. A rack portion 27 having a plurality of teeth is formed near the tip end of the tab 26. The teeth of the rack portion 27 are engaged with the protruding portions 37 of the slide plate 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 is projected. According to this configuration, when the first lifter plate 30 is moved (in the arrow direction in the drawing of fig. 2) such that the arm 35 is inserted into the slit 64 in a state where the first lifter plate 30 is superposed on the first back surface wall 20, the arm 35 is brought into contact with the guide plate 25. At the same time, the slider 36 contacts the adjustment piece 26 from below, and the hole 28 communicates with the long hole 38.

The pin 22 inserted into the upper end of the first long hole 31 of the first lifter plate 30 is fixed to the first back surface wall 20 in a state where the lower edge of the first back surface wall 20 coincides with the lower edge of the first lifter plate 30. In this way, the first lifting plate 30 is integrated with the first back surface wall 20 in a liftable manner. 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 relatively moves the pin 22 within the first long hole 31 and is lifted up in the inclined direction in which the first long hole 31 extends. The protrusion 37, which moves together with the arm 35 as the first elevating plate 30 is elevated, is engaged with any one of the teeth of the rack portion 27. The hole 28 communicates at the lower end of the long hole 38 when the tooth at the highest position of the rack portion 27 is engaged with the protrusion 37, and the hole 28 communicates at the upper end of the long hole 38 when the tooth at the lowest position of the rack portion 27 is engaged with the protrusion 37.

The second back wall 40 is an elongated flat plate with a plurality of second recesses 41 formed along the lower edge. Both ends of the second back wall 40 are connected to the front wall 10 by connecting rods 60. The length of the connecting rod 60 is set to be a distance between the first back wall 20 and the second back wall 40, which is about the width of the bottom of the trough 70. The connecting rod 60 connects the second rear wall 40 and the front wall 10 only at the upper portions thereof. 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 portion of the second back surface wall 40 where the second concave portion 41 is not provided is set to a height at which the lower edge of the second back surface wall 40 reaches the vicinity of the boundary between the bottom surface 73 and the rear inclined surface 74 when the second front surface wall 12 is brought into contact with the front 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 concave portion 41 is not provided, toward the back surface side. The lower end piece 45 is inclined upward, and the inclination angle is set to be equal to the inclination angle of the rear inclined surface 74 of the trough 70.

The second lifter plate 50 coincides with the second back wall 40 from the back side. A plurality of vertically long second long holes 51 are formed in the second elevating plate 50. Further, 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 apparatus 1 having the above-described structure will be described. When the feed is supplied into the trough 70 by the feed supply device 1, 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 rear wall 20 and the second rear wall 40 are respectively erected so as to sandwich 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 nozzle, not shown. As shown in fig. 3 (a), in a state where the lower end of the first back wall 20 coincides with the lower end of the first lifter plate 30, the space between the front wall 10 and the first back 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 lifter plate 30 covering the first concave portion 21 of the first back surface wall 20 is lifted up, and thereby the first concave portion 21 is partially exposed and the first opening S1 is formed between the first concave portion 21 and the bottom surface 73 of the trough 70 as shown in fig. 3 (b). Thereby, the feed is supplied from the feed storage 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 of the first elevating plate 30 can be adjusted stepwise by engagement of any one of the plurality of teeth of the rack portion 27 with the projection 37. The height of the adjusted first lifter plate 30 can be fixed by tightening bolts (not shown) passing through the holes 28 of the guide plate 25 and the long holes 38 of the arm 35 with nuts. The rack portion 27 having a plurality of teeth is formed on the tab 26 inclined with respect to the lifting direction (up-down direction) of the first lifting plate 30. Therefore, the first elevating plate 30 is moved up and down by a distance smaller than the moving distance of the protrusion 37 engaged with the teeth of the rack portion 27, and the size of the first opening S1 can be finely adjusted.

Further, since the arm 35 and the guide plate 25 are inclined outward, interference between the arm 35 and the guide plate 25 and a device for moving the feed supply device 1 by being connected to the hanger 69 from above, and a device having a hopper or a nozzle for introducing feed into the inlet 65 can be avoided.

As described above, when the feed is supplied from the first opening S1 to the trough 70, the lower edge of the second lifter plate 50 is aligned with the lower edge of the second back 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 of the trough 70 from which the feed supply device 1 is separated to supply feed is defined on the bottom surface 73. Therefore, by adjusting the size of the first opening S1 to adjust the amount of feed supplied from the first opening S1 to the trough 70, it is possible to set a limit period during which the feed is consumed and the chicken is starved, and also to cultivate the chicken in a normal state in which the chicken is not starved.

On the other hand, in a state where the feed is supplied from the first opening S1 to the trough 70, as shown in fig. 4 (b), the second elevating plate 50 is elevated relative to the second back wall 40. Then, as the second lifter plate 50 covering the second concave portion 41 of the second back surface wall 40 has been lifted up, the second concave portion 41 is partially exposed, and the second opening S2 is formed between the second concave portion 41 and the bottom surface 73 of the trough 70. Thus, the feed 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 of the second lifter plate 50, and the amount of feed flowing out onto the rear inclined surface 74 through the second opening S2 can be adjusted.

The second lifter plate 50 can be fixed to the second back wall 40 by fastening bolts 52 passing through the second long holes 51 to the screw holes 42. The height of the second elevating plate 50 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 opened, 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 very close to the chicken in the cage 90 and 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 bred in a fed state in which the feed is sufficiently consumed.

As described above, in the feed supply device 1 of the present embodiment, the first opening S1 is opened and closed by the lifting of the first lifting plate 30 relative to the first back wall 20, and the second opening S2 is opened and closed by the lifting of the second lifting plate 50 relative to the second back wall 40. Accordingly, the feed may be supplied only to the bottom surface 73 of the trough 70 in a state where the second opening S2 is closed, or may be supplied to a position close to the chicken 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 by which the first elevating plate 30 is elevated, and the size of the second opening S2 can be adjusted by the height by which the second elevating plate 50 is elevated. Thus, the amount of feed can be finely adjusted at each position where feed is supplied into the trough 70.

A space penetrating in the sliding direction is formed between the first back wall 20 and the second back 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 is not intercepted by the feed supply device 1, but can flow between the first back wall 20 and the second back wall 40. Therefore, the possibility of residual feed overflowing from the trough 70 due to 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 obliquely downward and short at the edge of the inlet 65. Therefore, when the feed is introduced from above through the inlet 65 and the feed storage space S0 is filled with feed, a space without feed remains below the upper edge piece 66. Further, the zigzag teeth 67 protrude downward at the end of the upper edge piece 66. This reduces the possibility of the fluidity of the feed being lowered by the feed being tightly packed in the feed storage space S0.

The second front wall 12 is a surface that contacts the front inclined surface 72 of the trough 70, and a shallow concave portion 19 is formed at the lower side. Therefore, a surface closing the lower end of the space between the front surface wall 10 and the first back surface wall 20 has a step corresponding to the thickness of the second front surface wall 12 in a portion as the second front surface wall 12 and a portion as the front inclined surface 72. With this step, when the feed supply device 1 is slid in the trough 70, vibration is applied to the feed filled in the feed storage space S0, so that the possibility of lowering fluidity due to dense feed can be reduced.

The present application has been described above with reference to preferred embodiments, but the present application is not limited to the above embodiments, and various modifications and design changes can be made without departing from the spirit of the present application.

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 teeth of the rack portion 27, and the like are not limited to the number shown in the figure.

The shapes of the first concave portion 21 and the second concave portion 41 are schematically shown as the shapes of the first back surface wall 20 and the second back surface wall 40, respectively, which are cut into trapezoid shapes. The present application is not limited to this, and the first concave portion 21 and the second concave portion 41 may be formed by cutting each into an arc shape or a triangle shape.
