Description

feed supply device

technical field

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

Background technique

In a facility for raising a plurality of chickens with a plurality of cages, a cage row in which a plurality of cages are arranged side by side in a horizontal direction is stacked in multiple 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 to the inside of a trough, the feed supply apparatus which slides inside a trough has been conventionally used. A general feed supply device includes: a feed storage part having an introduction port opened upward; and an opening formed at a lower part of the feed storage part. In such a feed supply device, the feed introduced from the hopper or nozzle provided above the feed supply device through the introduction port is accumulated in the feed storage portion, and a part of the feed is discharged into the trough through the opening portion.

The feed a chicken needs varies according to the growth process of the chicken. Therefore, the present applicant has also proposed a feed supply device in the past which can adjust the size of an opening for discharging the feed into the trough (refer to Patent Document 1).

However, in recent years, among chicken farmers, the idea has been permeating that chickens that are free to eat whenever they want may not necessarily grow larger. This is because chickens that are always given sufficient feed will have less desire to eat when they are full. On the other hand, chickens that are given insufficient feed time will become greedy for food intake. Therefore, the overall food intake will increase, and they will grow longer. larger. Therefore, based on such an idea, in order to supply the feed to the chickens, a feed supply device capable of adjusting the amount of the feed to be supplied to the trough with greater variety and precision is required.

SUMMARY OF THE INVENTION

Problem to be solved by the present invention

Therefore, the present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a feed supply device capable of variously and precisely adjusting the amount of feed to be supplied to a feeder.

solutions to problems

In order to solve the above-mentioned problems, the feed supply device of the present invention

"It is a feed supply device that slides in a trough for feed, and is characterized by:

The feed supply device has:

front wall;

a first back wall, a first recess is formed at the lower end;

a first lift plate, which overlaps with the first back wall, and rises and falls relative to the first back wall;

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

a second lift plate, which is coincident with the second rear wall, and is raised and lowered relative to the second rear wall; and

The introduction port is opened upward in order to introduce feed into the feed storage space between the front wall and the first back wall,

As the first lift plate rises relative to the first rear wall, a first opening is formed by exposing the first recess, and

As the second lift plate rises relative to the second rear wall, a second opening is formed by exposing the second recess. "

This feed supply device is used by sliding in the feed trough with the second back wall facing the cage. A first concave portion and a second concave portion are formed at the lower ends of the first back wall and the second back wall, respectively. In addition, a first lift plate and a second lift plate are respectively superimposed on the first back wall and the second back wall. The space between the front wall and the first back wall is a feed storage space, and an introduction port for introducing feed into this space is opened upward. Therefore, the feed can be stored in the feed storage space by introducing the feed into the inlet port from above using a hopper or a nozzle in a state where the first recessed portion is covered by the first lift plate.

When the first lift plate is raised relative to the first back wall, the first recess covered by the first lift plate so far is exposed, and a first opening is formed between the first recess and the inner surface of the chute. Therefore, the feed accumulated in the feed storage space flows out to the space between the first rear wall and the second rear wall through the first opening.

When the second lift plate is raised relative to the second rear wall, a second opening is formed between the second recess and the inner surface of the chute by exposing the second recess. Therefore, the feed flows out to the vicinity of the cage through the second opening from the space between the first rear wall and the second rear wall. 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 that the second lifting plate is raised and lowered. Therefore, it is possible to adjust the amount of feed supplied to the feeder through the second opening at a position close to and easily eaten by the chickens in the cage, and the chickens can be raised in a full-fed state in which the feed is fully eaten.

On the other hand, if the feed supply device is moved in a state where the second lift plate covers the second recess and the second opening is closed, the feed is supplied to the feed trough and is farther away from the guard than the position where the second back wall is located. The state of the cage position. In this way, when only the first opening is opened to supply the feed, the area in which the feed is supplied in the trough is smaller than when 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 that the first lifting plate is raised and lowered. Therefore, by adjusting the amount of feed supplied from the first opening, it is possible to set a limited period of time during which the chicken is starved by eating up the feed, and it is also possible to breed the chicken in a normal state that is neither starved nor full. .

As described above, in the present feed feeding device, the amount of feed can be adjusted for each position with a different distance from the cage by opening and closing the second opening and adjusting the respective sizes of the first opening and the second opening. , the supply of feed to the trough can be adjusted in a variety and precision.

On the basis of the above-mentioned structure, the feed supply device of the present invention,

It can be set as a structure which "the space between the said 1st back surface wall and the said 2nd back surface wall penetrates in a sliding direction".

Since the space between the front wall and the first back wall is a feed storage space, it is closed in the sliding direction of the feed supply device. The second rear wall needs to be spaced apart from the first rear wall, but a configuration in which both are connected so that the space between the first rear wall and the second rear wall 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, when the feed feeder moves in the trough where the feed remains, the feed may be intercepted by the feed feeder. Spill from hopper.

On the other hand, in this structure, the space between the 1st back surface wall and the 2nd back surface wall penetrates in a sliding direction. Accordingly, even if the feed remains in the trough, the feed flows into the space between the first rear wall and the second rear wall along with the movement of the feed supply device, so that the possibility of the feed overflowing from the trough can be reduced.

effect of invention

As described above, according to the present invention, it is possible to provide a feed supply device capable of variously and precisely adjusting the amount of feed to be supplied to a feeder.

In this way, the first lifting plate 30 is integrated with the first rear wall 20 so as to be able to be lifted and lowered. That is, when the arm portion 35 is brought into contact with the guide plate 25 and the arm portion 35 is pulled up, the first lift plate 30 relatively moves the pin 22 in the first elongated hole 31 and extends along the first elongated hole 31 . Inclined direction rises. The protruding portion 37 that moves together with the arm portion 35 in accordance with the lifting and lowering of the first lift plate 30 meshes 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 in the rack portion 27 engages with the protrusion 37 , and the hole 28 communicates with the protrusion 37 when the tooth at the lowest position in the rack portion 27 engages with the protrusion 37 . The upper ends of the long holes 38 communicate with each other.

The second rear wall 40 is an elongated flat plate, and a plurality of second recesses 41 are formed along the lower side. Both ends of the second rear wall 40 are connected to the front wall 10 by connecting rods 60 , respectively. The length of the connecting rod 60 is set to a distance on the left and right of the width of the bottom of the discharge chute 70 between the first rear wall 20 and the second rear wall 40 . In addition, the connecting rods 60 connect the second rear wall 40 and the front wall 10 only at their upper parts. Therefore, a space penetrating in the sliding direction is formed between the first rear wall 20 and the second rear wall 40 .

The height of the portion of the second rear wall 40 without the second recess 41 is set so that the lower side of the second rear wall 40 reaches the bottom surface 73 when the second front wall 12 is brought into contact with the front inclined surface 72 of the chute 70 . The height in the vicinity of the boundary with the rear inclined surface 74 . In addition, the lower end piece 45 extends from the lower side of the portion of the second rear surface wall 40 that does not have the second recess 41 toward the rear surface side in a short manner. The lower end piece 45 is inclined upward, and its inclination angle is set to be equal to the inclination angle of the rear inclined surface 74 of the trough 70 .

The second lift plate 50 overlaps with the second rear wall 40 from the rear side. A plurality of second elongated holes 51 that are long in the vertical direction are formed through the second lift plate 50 . Furthermore, the second rear wall 40 is provided with a screw hole 42 at a position communicating with the second long hole 51 .

Next, the usage method of the feed supply apparatus 1 of the above-mentioned structure is demonstrated. When the feed is supplied into the feed tank 70 by the feed supply device 1 , the feed supply device 1 is arranged inside the feed tank 70 . At this time, if the second front wall 12 is in contact with the front inclined surface 72 of the chute 70 and the lower end piece 45 is in contact with the rear inclined surface 74 of the chute 70, the first back wall 20 and the second back wall 40 They are respectively erected so as to sandwich the bottom surface 73 of the trough 70 .

The feed for the chickens is introduced into the introduction port 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 rear wall 20 is aligned with the lower end of the first lift plate 30 , the space between the front wall 10 and the first rear wall 20 is due to the distance between the feed supply device 1 and the first rear wall 20 . The troughs 70 are closed at the lower ends without a gap, and the feed is stored in the feed storage space S0.

When the arm portion 35 is pulled up as described above, the first lift plate 30 covering the first concave portion 21 of the first rear wall 20 so far rises, and as a result, as shown in FIG. 3( b ), the first concave portion 21 is partially exposed, and a first opening S1 is formed between it and the bottom surface 73 of the trough 70 . Thereby, the feed is supplied to the bottom surface 73 from the feed storage space S0 via the 1st opening S1. The size of the first opening S1 can be adjusted according to the height at which the first lifting plate 30 is raised, 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 the meshing of any one of the plurality of teeth of the rack portion 27 with the protruding portion 37 . The adjusted height of the first lift plate 30 can be fixed by tightening a bolt (not shown) passing through the hole 28 of the guide plate 25 and the long hole 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 ascending and descending direction (the vertical direction) of the first ascending and descending plate 30 . Therefore, the distance that the first elevating plate 30 is raised and lowered is smaller than the moving distance of the protruding portion 37 that meshes with the teeth of the rack portion 27, and the size of the first opening S1 can be finely adjusted.

Furthermore, since the arm portion 35 and the guide plate 25 are inclined outward, it is possible to avoid the arm portion 35 and the guide plate 25 and the device that is connected to the hanger 69 from above to move the feed supply device 1, and the feed introduction inlet can be avoided. 65 The hopper or nozzle device interferes.

As described above, when feed is supplied to the chute 70 from the first opening S1, as shown in FIG. In this state, when the feed supply device 1 is moved in the feed trough 70 , the area where the feed is supplied in the feed 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 opening S1 to adjust the amount of feed supplied to the trough 70 from the first opening S1, it is possible to set a limited period during which the feed is consumed and the chickens become hungry, and Chickens are raised in a normal state that does not become starved.

On the other hand, in the state where feed is supplied to the chute 70 from the 1st opening S1, as shown in FIG.4(b), the 2nd lift plate 50 is raised with respect to the 2nd back wall 40. Then, as the second lift plate 50 covering the second concave portion 41 of the second rear wall 40 so far ascends, 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 feed on the bottom surface 73 flows out onto the rear inclined surface 74 through the second opening S2. The size of the second opening S2 can be adjusted according to the height at which the second lift plate 50 is raised, and the amount of feed flowing out onto the rear inclined surface 74 through the second opening S2 can be adjusted.

The second lift plate 50 can be fixed to the second rear wall 40 by tightening the bolts 52 passing through the second elongated holes 51 to the screw 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 slope in the trough 70 after the feed supply device 1 is separated. Status on face 74. That is, the feed is supplied to a position very close to the chickens 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 raised in a full-fed state where the feed is fully eaten.

As described above, in the feed feeding device 1 of the present embodiment, in addition to opening and closing the first opening S1 by the lifting and lowering of the first lifting plate 30 with respect to the first rear wall 20 , the second lifting plate 50 also opens and closes the first opening S1 . The lifting and lowering of the second rear wall 40 opens and closes the second opening S2. Therefore, in the state where the second opening S2 is closed, the feed may be supplied only to the bottom surface 73 of the trough 70, or by opening the second opening S2, the feed may be supplied to a position close to and easy to eat by the chickens in the cage 90 feed.

In addition, the size of the first opening S1 can be adjusted by the height that the first lifting plate 30 is raised and lowered, and the size of the second opening S2 can be adjusted by the height of the second lifting plate 50 being raised and lowered. Therefore, the amount of feed can be fine-tuned at each position where feed is supplied into the trough 70 .

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

The feed supply apparatus 1 of this embodiment is provided with the upper edge piece 66 extended short and obliquely downward in the edge part of the introduction port 65. As shown in FIG. Therefore, when feed is introduced from above through the introduction port 65 and the feed storage space S0 is filled with feed, a space without feed is left below the upper edge piece 66 . Further, at the distal end of the upper edge piece 66, a zigzag tooth portion 67 protrudes downward. Thereby, the possibility that the fluidity|liquidity may fall by the feed closely filling in the feed storage space S0 can be reduced.

Moreover, the 2nd front wall 12 is a surface which abuts the front inclined surface 72 of the chute 70, and the shallow recessed part 19 is formed in the lower side. Therefore, the surface that closes the lower end of the space between the front wall 10 and the first rear wall 20 has a step corresponding to the thickness of the second front wall 12 between the second front wall 12 and 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 that the feed is densely filled and the fluidity is reduced can be reduced.

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

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

Moreover, as the shape of the 1st recessed part 21 and the 2nd recessed part 41, the lower end of the 1st back surface wall 20 and the 2nd back surface wall 40 is cut into a trapezoid shape, respectively, and is illustrated by illustration. Not limited to this, the first concave portion 21 and the second concave portion 41 may be respectively cut into a circular arc shape or a triangular shape.
