Description

[Detailed description of the invention] [Industrial application field] The present invention is a raised livestock barn consisting of a second floor room where livestock such as chickens are raised and a first floor room where livestock manure is stored. To provide a dropping guide device for livestock excrement which can efficiently guide livestock excrement in certain cases when dropping livestock excrement downstairs, and at the same time can effectively prevent harmful gases generated downstairs from going upstairs.

[Conventional technology]

The greatest advantage of the raised-bed livestock barns that have been constructed in large numbers in the past is that livestock manure can be stored downstairs for a long period of one to two years, which is labor-saving. However, on the other hand, harmful gases, mainly ammonia gas, generated by the fermentation of accumulated livestock manure, travel on the ventilation wheel and rise upstairs through the livestock manure drop opening in the floor of the second floor, which can affect the health of livestock and production. May have adverse effects on sexuality.

For this reason, as shown in, for example, Japanese Utility Model Publication No. 62-53671 or Japanese Patent Application Laid-Open No. 63-39525, the drop opening is covered with a receiving plate, and this receiving plate is rotated when ventilation or excrement is necessary. There is a device that can be slid slightly to open the drop port.

[The problem that the idea aims to solve]

However, in both of the above-mentioned techniques, animal feces falls and adheres to the receiving plate during the blockage, even if only temporarily, so that harmful gases end up staying in the second floor room.

In addition, the livestock manure that falls into the first-floor room is deposited in a mountain shape directly below the drop opening, resulting in poor drying and fermentation efficiency, and there is a limit to the amount that can be deposited.

The present invention was developed against the background of the above-mentioned circumstances, and allows for efficient and easy drying, fermentation, and subsequent feces removal of livestock excrement that accumulates on floors. The object of the present invention is to provide a livestock excrement fall guide device for a raised livestock barn that can suppress the flow of harmful gases to the livestock barn as much as possible.

[Means to solve the problem]

As a first means to achieve the above-mentioned object, the livestock excrement fall guide device of the present invention is provided in a raised-floor livestock barn with a dropping opening for livestock droppings opened on the floor of the second floor. A pair of guide plates are suspended in a room on the first floor, and the lower ends of both guide plates are connected with a gap narrower than the drop opening, and this gap is used as an outlet for livestock excrement, and one guide plate is formed of a flexible material, and this guide plate is supported so as to be able to be pulled up and down by a guide member disposed along one side of the lower part of the droplet, and the upper end of the other guide plate is connected to the lower part of the droplet. Rotatably supported on the other side.

In addition, as a second means, in a raised-bed livestock barn with an opening for dropping livestock feces on the floor of the second floor, a pair of guide plates are suspended from under the floor of the second floor to the first floor across the drop opening, and both The lower ends of the guide plates are connected with a gap narrower than the drop opening, and this gap is used as the excrement outlet, and the upper end of one guide plate is connected under the floor of the second floor room on one side of the drop opening. The upper end of the other guide plate is rotatably supported on the other side of the drop opening.

[Effect]

Feces excreted by the livestock on the floor slide down the inclined guide plate and fall downstairs from the outlet at the bottom. By pulling up and down or sliding one side of the guide plate to change the inclination angle, the discharge port at the lower end is moved to guide the dropping of livestock manure, and the depositing position can be freely changed. Therefore, it becomes possible to guide the livestock dung to the side and deposit it in a band shape. This increases the amount of deposition and
Drying and fermentation efficiency is improved.

In addition, the ventilation ring in the first floor room is guided to the floor of the first floor room along the guide plate, increasing the wind speed near the floor, effectively blocking harmful gases, and promoting the drying of livestock manure. Ru.

[Effect of idea]

Since the present invention is configured as described above, it is possible to effectively prevent harmful gases from rising from downstairs into the second floor room where livestock are housed, and the air in the second floor room can be kept clean. Furthermore, by operating the guide plate and moving the discharge port, the livestock manure can be deposited in a wide strip with an even thickness, thereby increasing the amount of deposited waste.

In addition, the guide plate blocks convection between the upper and lower rooms, increasing heat retention in the second-floor room, and since the air from downstairs is guided near the floor along the guide plate, the air above the accumulated livestock feces is removed. It moves well, accelerates drying, and increases the amount of deposits, making it possible to perform excrement removal work efficiently and easily.
