Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-floor poultry house capable of accumulating poultry manure under the floor, and more particularly to a feces removing apparatus under a high-floor poultry house cage row.

[0002]

2. Description of the Related Art A high-floor poultry house in which cage floors in which cage rows are arranged is set high and chicken manure falls from a gap between the floors is characterized in that chicken manure can be accumulated under the floor of the cage room. However, in a conventional high-floor poultry house, at least a dung receiving member such as a dung receiving sheet is not provided below at least the lowermost cage in the cage row, and at least chicken dung from the lowermost cage is dropped directly below the floor from the gap between the floors. Therefore, there was a tendency that the deposited chicken droppings did not take the shape of steep mountain ranges.

[0003] Further, when air taken into the poultry house from the outside is heated inside the house and discharged out of the house via the underfloor, since there is no feces receiving member below the lowermost cage, the air is taken out of the cage room. Since the flow rate of the air sent to the floor cannot be increased, and cannot be intensively sprayed on the deposited chicken dung, there is a drawback that the chicken dung is not sufficiently dried in combination with the shape of the deposited chicken dung.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned drawbacks of the prior art as much as possible, to steepen the shape of sedimentary poultry manure under the floor, and to discharge air discharged outside the house through the underfloor. The present invention is to provide a dung removal apparatus under a row of raised-fed poultry cages in which the dung can be sufficiently dried by intensively spraying the collected dung at a high flow rate.

[0005]

For this reason, in the feces removing apparatus according to the present invention, a plurality of long cage rows partitioned so as to accommodate an appropriate number of chickens in each cage are provided in a back-to-back multiple-stage manner. In the defecation equipment below the row of raised-fed cages,
A plastic dung receiving member for receiving chicken dung falling from the cage is provided below at least the lowermost cage of each cage row, and a scraper that moves periodically in the longitudinal direction while being in contact with the upper surface of the dung receiving member, It is characterized in that chicken dung deposited on the member is dropped under a raised floor through a central gap extending in the longitudinal direction of each cage row.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the defecation apparatus according to the present invention, as described above, it is essential that a feces receiving member is provided at least below the lowermost cage in each cage row. A scraper that is provided below each stage cage of each cage row and moves in the longitudinal direction while being in contact with the upper surface of the feces receiving member may be attached to the inside of the hopper feeder, and may be inserted from the front below each stage cage. Such a defecation device is preferably used for a so-called upright cage in which the front surfaces of the respective stage cages in the cage row are on the same vertical plane. In the case of this device, if each scraper is set to the working position, when the hopper feeder runs, feces are removed simultaneously with feeding.

[0007] Since the above-mentioned feces removal apparatus is not suitable for the so-called A-line cage, in which the front surface of each cage in the cage row advances from the upper row to the lower row, the feces receiving member is at least provided in the lowermost cage. As a scraper provided below and moving the upper surface of the feces receiving member in the longitudinal direction, a feces removing device which is a self-propelled wire-pulling scraper can be used. However, even in the case of an A-line cage, if the degree of advance of the front of each stage cage is small and it is a shape close to an upright cage, a feces receiving member and a scraper may be provided below the cage other than the lowest stage. it can.

According to the present invention, since a cheap and durable plastic sheet or plate such as polypropylene or polyvinyl chloride is used as the feces receiving member, it is compared with a plywood or cloth member such as a veneer plate. Although there is little torsion or bending, there is a possibility that it will be twisted or bent due to the weight of the deposited chicken dung.Therefore, a support member is placed at a position facing the scraper on the lower surface of the dung receiving member, and the support member is used to move the scraper. Accordingly, the feces receiving member can be supported from below. Hereinafter, the present invention will be described in more detail with reference to the drawings showing two embodiments of the feces removing apparatus according to the present invention.

[0009]

FIG. 1 is a front sectional view of an upright cage.
Is a cage of each stage, 2 is a bait gutter, 3 is an egg tray, 4 is a feces receiving sheet, 5 is a scraper, 6 is a front lever of a scraper, 8
Is a hopper feeder, and 9 is the central gap in the cage row. As shown in FIG. 1, the feces receiving sheet 4 (plastic having a thickness of 0.5 to 3 mm) is disposed on the ceiling of the cage directly below and below each step cage 1. In the lower cage, it is located below the cage and close to the floor.

A scraper 5 (which is at a rest position in FIG. 1) that moves in the longitudinal direction while contacting the upper surface of the feces receiving sheet 4 with the feces receiving sheet is provided inside a hopper feeder 8 that feeds the feed trough 2 of the cage 1. , And inserted under the cage 3 through the lower part of the egg tray 3. The dung removal operation by the scraper 5 described next is 1
Once every 3 days, the chicken dung on the dung receiving sheet 4 is pushed toward the central gap 9 of the cage row and falls under the floor immediately below the central gap 9.

According to FIG. 2, the scraper 5 is
It is connected to two levers (front lever 6 and rear lever 7) mounted on the lower front side of the vehicle, and can take a rest position 5 (shown by a solid line) and a working position 5 '(shown by a dashed line). . Since the scraper 5 is attached to the hopper feeder 8 via the levers 6 and 7, when the hopper feeder 8 moves to feed the feed trough 2, the scraper 5 also moves (from left to right in FIG. 2). What). Therefore, when trying to remove chicken droppings on the dropping sheet 4, the scraper 5 in the rest position is set to the working position 5 'and the hopper feeder 8 is operated to achieve the purpose.

FIG. 3 is a schematic front sectional view of the A-line cage. Below the lowermost cage 1 ', a feces receiving sheet 14 similar to that of the above-described embodiment, a scraper 15 and a feces receiving sheet 14 described next will be described. The support member 10 facing the scraper 15 can be seen on the lower surface of the device. In the case of the A-line cage, as described above, depending on the A-shape, the feces receiving sheet 14 may be provided only below the lowermost cage as shown in FIG. Since all the chicken droppings fall on the dropping sheet 14, it is particularly effective to provide the support member 10 in order to prevent twisting and bending of the dropping sheet. However, it goes without saying that the support member may be provided not only on the lowermost stage but also on the feces receiving sheet below the cage in the other stages.

With respect to the embodiment of FIG. 3, a self-propelled wire pulling scraper whose one embodiment is shown in FIG. 4 is often used. The scraper 15 is connected to the scraper frame 12 through a connecting pipe, and a guide bar 13 is connected to a center portion thereof. Both ends of the guide bar 12 are connected to both ends of the wire 11 for pulling the scraper 15 in the longitudinal direction. Is connected. Although the left and right scrapers 15 are paired, the length of the connecting pipe connected to the scraper frame 12 is different, so that the tip (the left side in the figure) of one scraper protrudes from the other as shown in FIG.

The wire 11 is moved while the scraper 15 is in contact with the upper surface of the feces receiving sheet 14 by driving a pulley (not shown) at one of the front end and the rear end of the cage row by a motor. (From right to left in FIG. 4), the chicken dung on the dung receiving sheet 14 is pushed toward the central gap 9 in the cage row and dropped under the floor. The support member 10, which faces the scraper 15 with the feces receiving sheet 14 interposed therebetween, moves while contacting the lower surface of the feces receiving sheet 14 with the movement of the scraper 15, and supports the feces receiving sheet from below to prevent its twisting and bending. . The self-propelled wire tow scraper briefly described here is disclosed in Japanese Patent Application Laid-Open No. Hei 8-
No. 33440.

[0015]

The feces removal apparatus under the row of raised-fed poultry cages according to the present invention has the above-described configuration and performs the accompanying actions, and therefore, has the following unique effects to the present invention. Can bring. (1) By providing the feces receiving sheet at least below the lowermost cage in the cage row, the dropping of the chicken droppings under the floor is almost limited to the central gap of the cage row, and as shown in FIG. Can be formed into a steep mountain range.

(2) Since the feces receiving sheet is made of plastic, the weight does not increase due to moisture absorption, and therefore, the twisting and bending of the feces receiving sheet can be prevented. (3) Since the air taken into the poultry house and heated in the cage room and blown under the floor is almost limited to the central gap, the blowing speed of the air is increased, and the warm air is concentrated on the accumulated chicken dung. By hitting, chicken dung is sufficiently dried (see FIG. 5).
