Description

  The present invention relates to a ventilation device in a poultry cage unit disposed in a poultry house.

  Generally, a poultry cage unit disposed in a poultry house is composed of, for example, a plurality of chicken cages that are formed of metal wires so as to have a gap as a whole. In the above chicken cage unit, in order to keep the inside of the poultry house hygienic and at the same time dry the chicken manure to some extent, the blower installed in the poultry house sends air into the poultry house and ventilates at the same time. .

  Specifically, as shown in FIG. 6, a pair of left and right chicken cages B1 and B2 are arranged in a plurality of stages in the vertical direction and in a row in the horizontal direction, and the rear surface of the chicken cages B1 and B2 A gap is provided in between, and the gap is used as a ventilation path extending in the vertical direction. On the other hand, the chicken cages B1 and B2 below the chicken cages B1 and B2 below the chicken cages B1 and B2 in the second and lower stages from the top. A feces container C that is inclined downward toward the ventilation path A is provided at a portion above the ceiling, and a belt conveyor D is provided below the lowermost chicken cages B1 and B2.

Then, the air flow from the blower E becomes a downward air flow through the air passage A and is blown onto the surface of each feces receptacle C to circulate outside the poultry cages B1 and B2, and each feces receptacle C dried by the airflow. The upper chicken droppings are dropped onto the belt conveyor D through the ventilation path A and are collected by the belt conveyor D. (See Patent Document 1)
By the way, the inventor of the present application widens the left and right chicken cages B1 and B2 that are independent from each other across the ventilation duct A in order to lay sperm eggs in the poultry house, and the right and left chicken farms. The cage B1 and B2 were connected to form a single room, and a chicken cage unit C was developed that accommodates multiple male and female chickens in this single large room. In the poultry cage unit, if the ventilation duct has the structure shown in the above publication, the air blown out from the ventilation duct will blow directly on the chicken in the chicken cage, which causes stress to the chicken in the cage. Can be considered.

In addition, conventionally, for example, as schematically shown in FIG. 7, a ventilation duct E extending in the longitudinal direction of the chicken cage unit C is arranged at the lower part of the chicken cages B1 and B2, and the wind from the blower is passed through the ventilation duct E. Although it has also been proposed to send it toward the feces receiving member F arranged below each of the chicken cages B1 and B2, in the above structure, the ventilation duct E extending in the longitudinal direction of the chicken cage unit C is proposed. Therefore, a large driving force is required for the blower, and there is a problem that the running cost becomes high as a whole. Also, since the ventilation duct E becomes long, for example, the upstream side of the ventilation duct E On the downstream side, the amount of air blown out from the outlet of the ventilation duct E is different, and there is a problem that, for example, it becomes impossible to dry chicken droppings smoothly.

  The present invention was developed in view of the above circumstances, and the first object is that the air flow blown from the ventilation duct is not directly blown to the chickens in the chicken cage, The purpose of the second aspect is to provide a ventilating device in a chicken cage unit that can efficiently dry chicken dung and ventilate the chicken cage, and the second object is to efficiently dry the dung even if the power of the blower is small. Therefore, it is to provide a ventilation device in a chicken raising cage unit that can reduce the running cost as a whole.

In order to achieve the above object, the invention described in claim 1 is characterized in that the chicken cages are arranged in a plurality of stages in the vertical direction and a large number of chicken cages are arranged in the longitudinal direction, and a dung collection member is arranged below the chicken cage. In the installed chicken cage unit, a wind tunnel body provided with a blower is disposed along the longitudinal direction above the chicken cage unit, and a plurality of ventilation ducts are provided at predetermined intervals in the longitudinal direction of the chicken cage unit. are, each ventilation duct, which is connected to the air channel, wherein the pipe in the vertical direction in the widthwise center position of the poultry cages unit and each ventilation duct, the upper and lower poultry cages of each stage and its lower A blowout port for sending wind toward the feces recovery member is provided between the feces recovery member.

  Further, the invention according to claim 2 is the ventilating device in the chicken cage unit according to claim 1, wherein a plurality of outlets are provided around the ventilation duct, and the wind from the ventilation duct is outward from the circumference of the ventilation duct. It is characterized by being blown out almost radially toward.

  According to invention of Claim 1, the wind sent through a ventilation duct is in the space between each chicken raising cage arrange | positioned in multiple steps up and down, and the dung collection member arrange | positioned therebelow Since it is sent directly to the feces recovery member, even if the power of the blower is small, the chicken excrement deposited on the feces receptacle can be efficiently dried and recovered, and the running cost associated with driving the ventilator as a whole is also Furthermore, since a part of the wind blown into the space between the poultry cage and the dung collection member acts in the poultry cage, ventilation in the poultry cage can be performed at the same time.

  In addition, the wind sent through the ventilation duct does not blow out directly into the poultry cage, so that the chicken manure deposited on the feces can be efficiently dried while being put into the chicken cage. The wind is not blown directly on the chickens that are being heated, and therefore, the chickens can be prevented from being stressed by the wind.

  In addition, while the chicken droppings on any dropping collection member corresponding to the chicken cages arranged in multiple stages above and below can be efficiently dried, the wind is directly applied to the chickens placed in the chicken raising cages at each stage. Blowing can also be suppressed, the difference in the amount of air blown from the outlet between the upper part and the lower part of the ventilation duct is small, and the pressure loss in the ventilation duct can be reduced.

  According to the chicken raising cage unit according to claim 2, in addition to the effect of the invention according to claim 1, the wind is blown out almost radially from the ventilation port of the ventilation duct toward the outer periphery of the ventilation duct. The chicken droppings on the droppings can be dried more efficiently.

  Hereinafter, a chicken cage unit according to the present invention will be described with reference to FIGS.

  FIG. 1 is a schematic explanatory view of a chicken cage unit according to the present invention, FIG. 2 is an explanatory view showing an enlarged main part thereof, FIG. 3 is a schematic plan view showing the main part partly cut away, and FIG. The perspective view of the principal part of a ventilation duct, FIG. 5 is the schematic explanatory drawing which looked at the chicken raising cage unit concerning this invention from the plane.

  As shown in FIG. 1, a plurality of chicken cage units 1 arranged side by side in the poultry house A have a pair of left and right chicken cages 2a and 2B arranged in a plurality of stages (six stages in the case shown in FIG. 1). In addition to being installed in parallel in the longitudinal direction of the chicken cage unit 1, the entire chicken cage unit 1 has a rectangular parallelepiped shape that is narrow in width and elongated in the column direction. The pair of left and right chicken raising cages 2a and 2B are arranged symmetrically with a ventilation duct 3 piped in the vertical direction.

  The ventilation duct 3 is formed in a rectangular cross section which is elongated in the lateral direction of the chicken raising cage unit 1. The ventilation duct 3 continuously extends from the upper end of the poultry cage unit 1 to substantially the lower end, and the upper end communicates with the wind tunnel body 4 disposed along the poultry cage unit 1 above the poultry cage unit 1. The air flow (wind) is sent to the ventilation duct 3 through the wind tunnel body 4 by driving the blower 40 incorporated at one end in the wind tunnel body 4.

  In the chicken cage unit 1 according to the present invention, the lengths of the respective chicken cages 2a and 2B assembled in a lattice pattern with thin metal wires are made longer than the conventional ones, and are opposed to each other with the ventilation duct 3 interposed therebetween. By removing the partition between the left and right poultry cages 2a and 2B and allowing the left and right poultry cages 2a and 2B to move back and forth, the left and right poultry cages 2a and 2B form a single chicken cage.

  In addition, as schematically shown in FIG. 5, the ventilation duct has a center in the longitudinal direction between the left and right chicken cages 2a and 2B, and one left and right adjacent to the left and right chicken cages 2a and 2B. It is arrange | positioned at two places near the boundary with chicken cage 2a * 2B, respectively.

  The upper and lower poultry cages 2a or 2B are arranged at an appropriate interval, and below each of the chicken cages 2a and 2B, a dung collection member 5 comprising a conveyor belt 50 of a belt conveyor is arranged. ing.

  In the middle of the ventilation duct 3, there is a wind near the surface of the feces collection member 5 in the space between the left and right chicken raising cages 2 a, 2 B at the upper and lower stages and the feces collection member 5 (almost parallel to this surface) An air outlet 30 is provided for sending out an air flow.

  As shown in FIG. 3, the air outlet 30 of the embodiment shown in the figure includes a first air outlet 31 for blowing air from the air duct 3 in a direction substantially orthogonal to the conveying direction of the conveyor belt 50, and the air duct 3. And a second blow-out port 32 for blowing air obliquely with respect to the conveying direction of the conveyor belt 50 so that the air is blown almost radially outward from the outer periphery of the ventilation duct 3. The second outlet 32 is provided with a guide plate 33 for guiding the wind blowing in a predetermined direction.

  The lower end of the ventilation duct 3 is opened downward in the space between the left and right chicken raising cages 2 a and 2 B and the feces collection member 5, and this opening is used as a blowout port 30.

  In addition, a cage-shaped feeding receiver 21 is provided along the longitudinal direction of the chicken cages 2a and 2B at the lower part of the front surface of each chicken cage 2a and 2B. An egg receiver 22 is provided for receiving an egg rolling from the lower surface of 2B.

  In the chicken cage unit 1 having the above structure, several male chickens and a large number of female chickens are housed in each of the left and right chicken cages 2a and 2B in one room to produce a sperm egg. is there.

  In the chicken cage unit 1 described above, with the drive of the blower 40, wind is sent to the ventilation duct 3 through the wind tunnel body 4, and the wind sent to the ventilation duct 3 is the left and right chicken cages 2a of each stage. -From the first and second outlets 31 and 32 provided below 2B, the space between the left and right chicken cages 2a and 2B and the dung collection member 5 is almost horizontal to the surface of the dung collection member 5 The wind is sent out in the direction, and it does not blow out directly into the chicken cages 2a and 2B.

  Specifically, as shown in FIG. 3, wind blows out from the first blowout port 31 in a direction substantially orthogonal to the conveying direction of the conveyor belt 50, and guides the guide plate 33 from the second blowout port 32. As a result, the wind blows obliquely with respect to the conveying direction of the conveyor belt 50, and as a whole, the chicken droppings deposited on the conveyor belt 50 are efficiently dried by blowing out radially outwardly around the ventilation duct 3. On the other hand, since the wind does not blow directly on the chickens placed in the chicken cages 2a and 2B, the chickens are not stressed by the wind.

  Moreover, the ventilation duct 3 arranged in the vertical direction directly sends out the wind toward the feces collection member 5 in the space between the poultry cage and the feces collection member 5 without loss, so even if the power of the blower is small The chicken droppings on the droppings collecting member 5 can be efficiently dried and collected, and the running cost associated with driving the ventilation device can be further reduced as a whole. Further, a part of the wind blown into the space between the poultry cage and the dung collection member 5 acts in the poultry cages 2a and 2B, so that the ventilation in the poultry cages 2a and 2B can be performed at the same time.

  In addition, the difference in the amount of air blown from the air outlets 31 and 32 between the upper part and the lower part of the air duct 3 is small, and furthermore, the distance from the blower to each air outlet 31 and 32 of the air duct is short, The pressure loss in the ventilation duct 3 can also be reduced.

Furthermore, since a part of the wind blown into the space between the left and right chicken cages 2a and 2B and the dung collection member 5 of each stage is weakened, the air flows into the left and right chicken cages 2a and 2B. It is done at the same time.

  In the above embodiment, a pair of left and right poultry cages 2a and 2B in one room are arranged in six stages in the vertical direction and many are arranged in the horizontal direction. However, the present invention is not limited to this. The left and right chicken raising cages 2a and 2B may be arranged in four stages in the vertical direction.

  Moreover, in the above embodiment, the length in the longitudinal direction of each of the chicken cages 2a and 2B assembled in a lattice pattern with thin metal wires is made longer than before, and the left and right chicken cages facing each other with the ventilation duct 3 interposed therebetween. The partition between 2a and 2B is removed, and the left and right poultry cages 2a and 2B can be moved back and forth. However, the present invention is a chicken cage unit in which the length in the longitudinal direction of each of the chicken cages 2a and 2B is shortened as before. May be applied, or a partition may be provided between the left and right chicken cages 2a and 2B.
