[0002]

2. Description of the Related Art Previously, the applicant of the present application has proposed a defecation belt scraper as this type of defecation mechanism.
48691). That is, this scraper is pressed by a belt for transferring chicken droppings to remove the chicken droppings, and the scraper is pressed to the belt at a position rearward of the scraping portion,
And an extended contact portion for scraping off the chicken droppings on the belt left by the scraping portion.

Then, the chicken droppings are transferred on the belt, and are first scraped off by the scraping portion pressed against the belt,
The chicken manure left behind by the scraping portion is scraped off by the extension contact portion which is pressed against the belt behind it.

[0004]

However, the conventional defecation belt scrapers are provided at the end portions of the defecation belts arranged in each stage. Therefore, when the scraper is pressed against the belt to allow the feces to be removed and the scraper is set to the non-operation position where the scraper can be separated from the belt to allow cleaning, the lever must be operated for each step. .

Therefore, there has been a problem that the number of times of operation is increased, the operation is troublesome, and the operation takes time. Moreover, since there is an operation lever for each step,
There is a problem that the number of parts is large and the configuration is complicated.

The present invention has been made in view of the above problems. An object of the present invention is to provide a defecation mechanism in a bird-and-animal breeding apparatus in which the operation of setting the scraper to the working position and the non-working position is easy and quick, and the number of parts is reduced to simplify the configuration.

[0007]

In order to achieve the above object, the defecation mechanism in the bird and animal rearing apparatus according to the first aspect of the present invention is rotatably arranged in upper and lower stages, respectively.
A transport mechanism equipped with a belt for transporting a large number of bird and animal feces housed in each stage, and a first scraping unit disposed at the end of this transport mechanism for scraping the feces on the belt and a position behind it. A scraper having a second scraping portion arranged to scrape off the feces left behind by the scraping portion, an operating position at which the scraper is scraped off, and a non-acting position at which the scrape is not scraped are set or An operation mechanism having an operation lever to be released,
A plurality of operation mechanisms are connected to each other, and an interlocking mechanism for simultaneously operating the operation mechanisms of the respective stages with an operation lever is provided.

According to a second aspect of the present invention, in the first aspect of the invention, the operating mechanism connects a plurality of links and sets the scraper at an operating position and a non-operating position by interlocking each link. It is characterized by having a link mechanism.

[0009]

When the operating lever is operated, the operating mechanism of a plurality of stages is simultaneously converted from the released state to the set state through the interlocking mechanism, and the scraper in the non-acting position is changed to the acting position. In this state, when the birds and beasts' feces are conveyed by the belt and reach the end, the first scraping portion of the scraper comes into contact with the belt and scrapes the feces on the belt. Further, when the belt circulates, the second scraping portion comes into contact with the belt to scrape the feces left on the belt by the first scraping portion.
