Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, a defecation apparatus incorporated in a cage row in a poultry house to remove chicken manure.

[0002]

2. Description of the Related Art Conventionally, for example, removal of chicken manure in a poultry house has been performed as follows. That is, in FIG. 6, the floor of the cage layer 39 is at a high position, so-called,
A stilt house 40 is shown. In this stilt poultry house 40, chicken droppings dropped from cages 41 arranged in a plurality of stages fall through grooves 42 formed on the floor surface of the cage layer 39 and are provided below the cage layer 39. Chicken pond reservoir 4
3 is to be deposited. Then, the chicken dung K accumulated in a certain amount in the reservoir 43 is scraped out of the poultry house 40 by using a machine such as a bulldozer or manually.

Although not shown, a so-called so-called type in which the chicken dung storage layer 43 is not provided below the cage layer 39 in FIG.
In the low-floor poultry house, for example, similar to the arrangement of the cages 41 shown in FIG. 6, the pair of left and right cages are arranged such that the closer they are located on the lower stage side, the wider the intervals are.
Then, on the floor surface of the poultry house, chicken dung is accumulated in pits (grooves) provided between the cages, and the dung is discharged by a pit scraper traveling in the pit.

[0004]

However, in the high floor type poultry house, the floor of the cage layer 39 is provided in order to bring the equipment into the chicken dung storage layer 43 and to provide a space in which the worker can easily work. The poultry house 40 is inevitably high because of the high price, and the construction cost is high. Moreover, ammonia gas, flies, etc. are generated in the aged chicken manure K, and the defecation work in a narrow closed space is unhygienic for the worker and a painful work.

In a low-floor poultry house, it is not necessary to set a large cage interval. Therefore, as a drawback of this low-floor type poultry house, since the chicken dung accumulated in the pit exists in the vicinity of the cage, the offensive odor of ammonia gas or the like generated remains in the poultry house and adversely affects the defecation worker. Further, maintenance of the pit scraper must be performed in a narrow space, which is extremely difficult. Furthermore, since the distance between the deposited chicken dung and the cage is closer than in the stilt system, the generation of the above-mentioned ammonia gas, flies, and the like not only adversely affects the worker, but also causes pathology to the chicken.

In addition to the above-mentioned prior art, a belt conveyer device is arranged on the floor of the poultry house in the low floor poultry house along the longitudinal direction of the cage row so that the poultry manure received on the conveyor belt reaches one end of the cage row. There is also the idea of transporting and discharging. However, if this belt conveyor device is incorporated as a device separate from the structure of the cage row, the support structure of the device must be provided separately from the support structure of the cage line, which secures the installation space and reduces the installation cost. From the point of view, it has not been realized at this point.

The present invention has been made by paying attention to the problems existing in the above-mentioned prior art, and the purpose thereof is to easily remove chicken droppings without forcing the operator to perform laborious work. An object of the present invention is to provide a defecation apparatus that can reduce the installation cost.

[0008]

In order to achieve the above object, according to the invention of claim 1, a plurality of cages are arranged at the lower ends of the columns of a cage row supported by the columns and dropped from the cages. A defecation apparatus that receives feces from a cage row and conveys it to one end side of a cage row, the casing extending in the cage row direction and having an open upper surface, a drive roller supported on one end side in the casing, and the other end. The defecation apparatus is composed of a driven roller supported on the side and an endless conveyor belt wound between the rollers, and the casing is fixedly supported by a support column that supports a cage.

According to the second aspect of the invention, the edge of the opening in the casing extending in the cage row direction is inclined toward the conveyor belt. In the invention of claim 3, the conveyor belt is made of resin, and a belt supporting member for supporting the conveyor belt is disposed between the driving roller and the driven roller in the casing, and the belt supporting member is the casing. The upper conveyor belt exposed in the opening is bent to support the central portion of the upper conveyor belt at a position lower than the side portions.

[0010]

According to the first aspect of the present invention having the above-mentioned structure, the feces dropped from each cage are received through the opening of the casing disposed below the cage and onto the conveyor belt exposed at the opening. By the positive rotation of the drive roller, the conveyor belt wound between the driven roller and the driven roller is rotated, and the feces on the belt are conveyed to one end of the cage row. Since the casing is fixedly supported by the support pillars for supporting the cages, it is not necessary to separately provide a supporting structure when the feces decontamination device is incorporated in the cage row, and the installation cost can be reduced.

In the second aspect of the present invention, the dropping edge near both edges of the conveyor belt also has an opening edge of the casing that is inclined, so that the dropping enters the gap between the belt and the casing. There is no. In addition, since the gap between the conveyor belt and the casing becomes small, feces during transportation do not enter the casing.

According to the third aspect of the present invention, the feces can be collected and conveyed in the central portion of the conveyor belt by setting the central portion of the conveyor belt at a lower position than both side portions.
Therefore, particularly when embodied in the invention of the second aspect, it is possible to prevent feces from entering the casing.

Next, the transport mechanism 15 held by the casing 14 will be described. As shown in FIG. 2B, the drive roller 16 is rotatably supported between the main frames 10 at the right end in the figure. As described above, the side surface of the main frame 10 is inclined inward along the inner side surface of the support column 3, but in the vicinity of both ends outside the cage 2 (rollers 16, 17, In the vicinity of 18), the side surface is configured to be perpendicular to the floor surface Y.

The driven roller 17 is also the main frame 1
Between 0, it is rotatably supported at the left end of FIG. The pressure roller 18 is rotatably attached to the drive roller 16
And a minute gap is formed between the peripheral surface and the peripheral surface of the drive roller 16. The scraping member 19 is arranged to face the peripheral surface of the drive roller 16 and
It has two blades 20 extending in the same direction.

The endless resin conveyor belt 21 is
It is wound around the drive roller 16 and the driven roller 17. The conveyor belt 21 passes between the peripheral surfaces of the pressure roller 18 and the drive roller 16 via the upper surface side of the pressure roller 18. Since the gap between the peripheral surfaces of the drive roller 16 and the pressure roller 18 described above is slightly smaller than the thickness of the conveyor belt 21, the conveyor belt 21 includes both rollers 16,
It will be clamped by 18 with an appropriate pressure. Also,
The two blades 20 of the scraping member 19 are urged by an elastic member such as a coil spring (not shown), and the tip ends of the two blades 20 on the drive roller 16 with an appropriate pressing force.

1 is pulled by the winding force of the rollers 16 and 18 that hold it, and is rotated in the clockwise direction in FIG.

In the feces removal apparatus 6 of this embodiment, its casing 14 is supported by the support column 3 which supports the cage 2. That is, in each of the columns 3, the casing 14 is held and fixed to the column 3 by bolting 29 to the overlapping portion of the upper part of the main frame 10 with the subframe 11 and the lower part of the main frame 10.

Next, the operation of the defecation apparatus 6 will be described. The chicken manure received on each manure receiving sheet 4 from each cage 2 in the upper middle stage is scraped off by the scraper 5 and dropped onto the conveyor belt 21 exposed at the upper opening 9 of the casing 14 through the discharge gap H. Further, it is dropped directly from the lower cage 2 onto the conveyor belt 21.

The transport belt 21 that has received the chicken manure is bent at the center due to the weight of the chicken manure, but is supported by the upper belt support member 12 in accordance with the bent shape of the transport belt 21. Then, the conveyor belt 21 is sent by the operation of a switch (not shown), and the conveyor belt 21 is supported and sent in a state where the central portion of the conveyor belt 21 is bent, and chicken feces are collected in the central portion by the conveyor surface inclined toward the central portion. Can be transported.

The circling movement of the conveyor belt 21 causes the chicken dung sent to the right in FIG. 2 to be scraped off by the two blades 20 of the scraping member 19 and directed toward a chicken dung collecting device (not shown) or the like. Is discharged. As described above, since the chicken droppings can be easily discharged by any operation of the defecation apparatus 6, the discharging operation can be performed more frequently and the sanitary condition in the poultry house can be improved as compared with the conventional technique. As described above, the discharge work can be easily performed without requiring the worker, so that the worker can be freed from the conventional unhygienic and troublesome work.

In the present embodiment having the above-mentioned structure, the casing 14 holding the transport mechanism 15 is supported and fixed to the support column 3 supporting the cage 2. Therefore, it is not necessary to separately provide a supporting structure for supporting the defecation apparatus 6 in the cage row 1, the installation cost can be suppressed, and the apparatus can be made compact.

The poultry manure from the upper middle cage 2 has a certain directionality (toward the central portion of the conveyor belt 21) through the discharge gap H by the constitution of the feces receiving sheet 4 and the scraper 5. Although dropped, chicken droppings from the cage 2 in the lower stage are dropped directly on both sides of the conveyor belt 21. However, in this embodiment, the mainframe 10
The upper edge of the opening forms a slope 10a that is inclined inward. Therefore, the edge of the conveyor belt 21 and the frame 1
It is possible to prevent chicken droppings from entering between 0 and 11. As a result, it is possible to save the trouble of cleaning the gap between the edge of the conveyor belt 21 and the frames 10 and 11 where it is difficult to put a hand. Since the conveyor belt 21 is inclined and sent to the center side, the chicken dung can be conveyed in the center of the belt 21, the chicken dung is scattered on both sides, and from the gap between the slope 10a and the surface of the conveyor belt 21. It is possible to prevent chicken droppings from entering the casing 14. As described above, making the edge (10a, 11a) of the opening 9 into a slope reduces the gap between the surface of the conveyor belt 21 and the chicken dung during transportation, which is difficult to enter into the casing 14 as described above. It is also effective in that

Further, the conveyor belt 21 includes the driving roller 16
It is wound between the driven roller 17 and the driven roller 17 without tension. Therefore, the degree of fatigue damage of the conveyor belt 21 can be suppressed.

Moreover, the revolving movement of the conveyor belt 21 is carried out by being pinched by the driving roller 16 and the pressure roller 18, which are positively rotated, with a proper pressure. Therefore, even if the conveyor belt 21 is caught on the casing 14 for some reason and the revolving movement is stopped, both rollers 16,
18 slides on the conveyor belt 21 to release the load, and seizure of the geared motor 26 can be suppressed.
