Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chicken breeding plant, and more particularly to a plant most suitable for raising a large number of chickens.

[0002]

2. Description of the Related Art A poultry house for 100,000 chickens is 20 a day.
Generates chicken droppings from the ton. The amount of poultry manure generated limits the number of chickens that can be raised. This is because foul odor pollution is scattered around when the number of breeding is increased. However, in order to produce high quality chicken, it is necessary to raise a large number of chickens in a highly controlled poultry house. In order to realize this, it is earnestly desired to develop a technique for increasing the throughput of chicken manure.

In particular, chicken breeding plants for broilers have more difficult problems than chicken breeding plants for spawning. This is because chickens for broilers are basically raised in the soil. When breeding chickens for broilers on a lattice floor through which poultry manure passes, like breeding chickens, it is impossible to breed high-quality broilers. This is because the lattice floor causes chicken "breast octopus". Therefore, it is important to raise chickens for broilers on the ground. However, in reality, it is difficult to raise all chickens in the soil, and the fact is that they are raised on an iron plate or the like. Chickens cannot be bred directly on the iron plate. It is necessary to place rugs, such as chips and wood chips, cut into small pieces of wood on the iron plate and raise them on it.

[0004]

[Problems to be Solved by the Invention] When chickens are laid with a rug, it becomes more difficult to treat chicken droppings. This is because poultry manure contains wood chips and the like, which makes it difficult to treat poultry manure and cannot be used as an organic fertilizer. Chicken manure mixed with wood chips must be incinerated and discarded. When incinerating 20 tons of chicken dung each day, a huge amount of heat energy is required. In particular, since chicken manure contains 60-80% of water, there is a drawback that a large amount of heat energy is consumed for incineration. Further, when the chicken manure is incinerated, a significant foul odor is emitted to the surroundings and causes pollution.

Chicken manure contaminated with wood chips can be used as a fertilizer if the contaminants are completely rotted. However, in order to completely spoil wood chips and chips, it is necessary to leave chicken manure under specific conditions for at least several tens of days. Therefore, it is extremely difficult to realize this in reality. In particular, it cannot be used at all in plants that breed large numbers of chickens.

Furthermore, the plant for breeding chickens for broilers on which a rug such as wood chips is placed has a drawback that the number of breeding chickens per unit area is extremely limited. By the way, it is said that the number of breeding animals per square meter is preferably 10 or less. When the number of breeding is increased, the dung is not dried and the floor becomes moist, and bacteria are propagated and cause diseases. For this reason, chickens, especially chickens for broilers, have a drawback that they have a large breeding area and cannot be efficiently raised.

[0007] The present invention was developed for the purpose of solving the problems that are now longing for chicken breeding. An important object of the present invention is to provide a chicken breeding plant capable of raising chickens of high quality, simplifying the treatment of chicken droppings, and further recycling the chicken droppings as an effective fertilizer.

[0008]

The chicken breeding plant of the present invention has the following constitution in order to achieve the above-mentioned object. (A) The breeding plant comprises a breeding apparatus 1 for breeding chickens,
It has a chicken manure processing device 2 for treating chicken manure, and a chicken manure return transfer means 3 for supplying the treated chicken manure to the breeding device 1. (B) The breeding apparatus 1 includes a breeding conveyor 4 arranged on the floor of the breeding room 5. (C) The poultry manure processing device 2 includes a drying unit 6 that dries chicken manure in a heated state. Furthermore, preferably, the poultry manure processing device 2 includes a mixer 7 for adding quick lime to poultry manure. (D) The return transfer means 3 is connected to the chicken manure processing device 2 and the breeding device 1, and is configured to supply the treated manure heated and dried by the chicken manure treating device 2 to the breeding conveyor 4 of the breeding device 1. Has been done.

[0009]

The chicken breeding plant of the present invention recycles chicken droppings to breed high quality chickens. To achieve this, chicken manure is effectively reused. That is, the chicken breeding plant of the present invention circulates chicken manure as follows,
Keep chickens in a comfortable environment and produce high quality organic fertilizer. The chicken makes feces on the feeding conveyor 4. The chicken manure on the breeding conveyor 4 is transferred to the chicken manure processing device 2. The chicken manure processing device 2 heats and dries chicken manure. In this step, the chicken dung is sterilized by heating, and the water is removed to be treated dung. The water content of the treated feces is preferably 3
It is adjusted to 0% or less, more preferably 20% or less. A part of the sterilized and dried treated feces is supplied to the breeding conveyor 4 of the breeding apparatus 1 by the return transfer means 3 and laid on the breeding conveyor 4. The treated feces not returned to the breeding apparatus 1 by the return transfer means 3 are effectively used as organic fertilizer. The treated feces supplied on the breeding conveyor 4 adsorb the moisture of the feces that the chickens obscene, and keep the dried feces in a dry state. The treated feces adsorb the moisture of the feces spoiled from the chicken and vaporize the adsorbed moisture. When the amount of water in the treated feces increases, the treated feces are transferred from the breeding conveyor 4 to the chicken manure processing device 2, and new treated feces are carried in from the chicken manure processing device 2. The chicken breeding plant of the present invention breeds chickens by repeating the steps of to produce organic fertilizers.

However, the members shown in the claims are not limited to the members of the embodiment.

The chicken breeding plant shown in FIG. 1 includes a breeding apparatus 1 for breeding chickens, a chicken droppings processing apparatus 2 for treating chicken droppings, and
It has a return transfer means 3 for feeding the treated poultry manure to the breeding apparatus 1.

As shown in FIG. 2, the breeding apparatus 1 includes a breeding conveyor 4 arranged on the floor of a breeding room 5. The breeding conveyor 4 is horizontally provided so that chickens can be raised on the breeding conveyor 4. The breeding conveyor 4 is used as a breeding room 5 for chickens in which the upper surfaces of both upper and lower belts are divided in order to efficiently breed chickens. In the breeding apparatus 1 shown in FIG. 2, breeding conveyors 4 are arranged in upper and lower four stages, and the number of breeding chickens is eight.

FIGS. 3 and 4 show the plane and side surfaces of the breeding conveyor 4. Breeding conveyor 4 shown in these figures
Includes a floor plate 8 and a chain 9 that drives the floor plate 8 by connecting the floor plate 8 in a belt shape.

The floor plate 8 tilts vertically from a horizontal posture with one side (left side in the drawing) as a center. As shown in FIG. 5, the cross-sectional shape of the floor plate 8 is such that both ends are bent into a tubular shape to form a reinforcing rib. The floor plate 8 having this shape is reinforced by the ribs at both ends to realize sufficient bending strength. The rotary shaft 10 is inserted into the left end cylinder of the floor plate 8. Both ends of the rotary shaft 10 are fixed to the inside of the connecting piece 11 of the chain 9. The floor plate 8 having this structure is rotatably inserted into the rotary shaft 10. However, although not shown, it is also possible to fix the rotating shaft 10 to the floor plate 8 and rotatably connect it to the connecting piece 11 of the chain 9.

If the breeding conveyor 4 is moved slowly without opening the partition wall 12, the feces adhering to the breeding conveyor 4 can be transferred without moving the chickens. In order to realize this, for example, the breeding conveyor 4 is slowly moved to reciprocate once a day, and the breeding conveyor 4 moved to the fecal removal chamber is continuously washed and sterilized with hot air. In this state, the breeding conveyor 4 can be washed daily. Breeding conveyor 4
By reciprocating once every two days, you can wash and sterilize with hot air once every two days.

The breeding conveyor 4 supports the lower surface of the floor plate 8 and holds it in a horizontal posture. If the lower surface of the floor plate 8 is not supported, it tilts vertically due to its own weight. A horizontal guide 13 is provided below the breeding conveyor 4 to support the lower surface of the floor plate 8. The horizontal guide 13 holds the floor plate 8 in a horizontal posture by placing the floor plate 8 thereon and sliding it. The horizontal guide 13 is a portion that holds the floor plate 8 horizontally,
In other words, it is provided at a portion of the breeding conveyor 4 excluding both ends. When the floorboard 8 moves in the descending portion of the horizontal guide 13, the floorboard 8 hangs vertically by its own weight, and the chicken droppings placed on the floorboard 8 are dropped to the lower stage.

In FIG. 2, at both end portions of the breeding conveyor 4, there is disposed a feces removing means 14 for neatly removing adhering feces. The feces removing means 14 includes a rotating brush 15 for scraping off feces adhering to the feeding conveyor 4, a washing nozzle 16 for injecting a washing liquid, a washing liquid pump 17 for supplying a pressurized liquid to the washing nozzle 16, and a raising conveyor 4. Hot air drying and disinfecting means 1 for blowing hot air to dry and disinfect the cleaning liquid
9 is equipped.

The rotating brush 15 removes feces from the breeding conveyor 4 on which the chicken is dropped. The rotating brush 15
The brush is rotatably provided in parallel with the rotating shaft 10 of the sprocket on which the breeding conveyor 4 is placed so that the tip of the brush comes into contact with the breeding conveyor 4. The end of the rotating belt is connected to a motor (not shown) and is rotated by the motor.

The cleaning nozzle 16 sprays the cleaning liquid onto the breeding conveyor 4 from which the feces have been removed by the rotating brush 15 to clean the cleaning cleanly. The cleaning nozzle 16 sprays the cleaning liquid on both sides of the breeding conveyor 4. Therefore, both the cleaning nozzle 16 that sprays the cleaning liquid on the outside of the breeding conveyor 4 and the one that sprays the cleaning liquid on the inside are fixed toward the breeding conveyor 4. As the cleaning liquid, a liquid that cleanly removes feces on the breeding conveyor 4 and further sterilizes the liquid is used.

The cleaning liquid pump 17 pressurizes the cleaning liquid and supplies it to the cleaning nozzle 16. The discharge side of the cleaning liquid pump 17 is connected to each cleaning nozzle 16, and all cleaning nozzles 1
The cleaning liquid is sprayed from 6.

The breeding conveyor 4 is slowly driven by the reduction motor 21. The deceleration motor 21 drives the sprocket 20 on which the chain 9 of the breeding conveyor 4 is hung.
Therefore, the reduction motor 21 is connected to the shaft of the sprocket 20 via the drive chain. Below the lowermost breeding conveyor 4, a discharge conveyor 22 for discharging chicken manure from the breeding apparatus 1 is connected.

The chicken breeding apparatus 1 shown in FIG. 2 is provided with a plurality of compartments 5 above the breeding conveyor 4 with the partition wall 12. The partition wall 12 is mounted so as to be rotatable in a vertical plane. The partition wall 12 partitions the upper part of the breeding conveyor 4 into a plurality of breeding rooms 5 in a vertical posture. When the breeding conveyor 4 is driven with the partition wall 12 held in a vertical posture, only chicken droppings can be transferred without transferring chickens. When discharging the grown chicken, the partition wall 12 is horizontally rotated. The horizontally rotating partition wall 12 does not partition the breeding conveyor 4 and allows the chicken to move together with the breeding conveyor 4.

The partition 12 has a rotating shaft (not shown) fixed along the upper edge thereof. Both ends of the rotating shaft are attached to the house via bearings. Further, although not shown, a cylinder (not shown) for rotating the partition 12 by 90 degrees is connected to the rotating shaft.

The chicken manure processing device 2 to which the chicken manure is sent from the discharge conveyor 22 dries the chicken manure in a heated state. Therefore, as shown in FIGS. 6 to 8, the poultry manure processing device 2 includes a mixer 7, a heating chamber 25 and a burner 26 that are drying means 6, and a drying conveyor 23 that transfers poultry manure.

The mixer 7 adds quicklime to the chicken manure sent from the breeding apparatus 1 by the discharge conveyor 22 and stirs it. The mixer 7 opens a discharge port on the bottom plate of the cylindrical case,
A stirring blade is provided above the bottom plate. The stirring blade is fixed to a rotating shaft that penetrates the center of the bottom plate, and the rotating shaft is connected to a motor and rotated.

The upper part of the mixer 7 is connected to the breeding apparatus 1 via the discharge conveyor 22. The discharge conveyor 22 is arranged at the bottom of the breeding apparatus 1 and transfers the chicken manure of the breeding apparatus 1 to the mixer 7. The outlet of the mixer is connected to the drying conveyor 23 via a screw conveyor. Further, as shown in FIG. 1, a quick lime supply means 24 is connected to the upper portion of the mixer 7. Quicklime supply means 24
Rotates the coil in the cylinder and transfers it. The coil is rotated by a reduction motor to supply quick lime in the hopper to the mixer 7. The amount of quicklime added to the mixer 7 is adjusted within the range of 3 to 10% by weight with respect to chicken manure. When 5% by weight of quicklime is added to chicken manure, about 5% by weight of water in chicken manure can be evaporated by the heat generated by quicklime. When the amount of quicklime added is increased, the heating temperature of chicken manure can be increased and the fermentation and drying times can be shortened.

In addition to quick lime, phosphoric acid can be added to the mixer 7. The phosphoric acid reacts with the ammonia gas generated in the mixer 7 to generate phosphorus ammonium. Ammonia gas generated in the mixer 7 can be reduced by adding phosphoric acid. The amount of phosphoric acid added is 0.1 for 100 g of chicken manure.
Adjusted to ~ 2.5 g range.

The heating chamber 25 heats and dries the fed chicken manure. In this process, chicken manure is fermented. The walls of the heating chamber are insulated to prevent heat from escaping to the outside. The heating chamber 25 has a burner 26 penetrating the wall. The burner 26 heats the internal temperature of the heating chamber to 30 ° C. or higher. If the room temperature is kept high,
It can promote high temperature fermentation of chicken manure. For this reason, chicken manure is dried in a short time to become organic fertilizer. In the heating chamber 25,
A plurality of stages of drying shelves 27 are provided inside so that a large amount of poultry manure can be efficiently dried.

The drying conveyor 23 has a structure similar to that of the breeding conveyor of the breeding apparatus, in which chicken dung is dropped to the lower stage when it is transferred to the end. An auger 28 is arranged above the drying conveyor 23 in order to drop or evenly poultry manure supplied from the mixer 7 to a uniform thickness.

The return transfer means 3 supplies the dried chicken manure to the breeding apparatus 1. Therefore, the return transfer means 3
Is connected to the chicken manure processing device 2 and the breeding device 1.
A part of the processed feces sent from the chicken manure processing device 2 is supplied to the breeding device 1 by the return transfer means 3, and the rest is shipped as fertilizer. The return transfer means 3 is the breeding apparatus 1 first
The amount of treated feces to be supplied to the breeding conveyor 4 is several cm.
Adjust the amount of treated feces to be laid. When the thickness of the treated feces on the breeding conveyor 4 becomes thin, the proportion of the treated feces supplied to the breeding conveyor 4 is increased and the proportion of the treated feces taken out as fertilizer is reduced. On the contrary, if the treated feces on the feeding conveyor 4 become thicker, the proportion of the treated feces taken out as fertilizer is increased. As the return transfer means 3, any means capable of transferring the treated feces, for example, a belt conveyor or the like is used.

[0031]

INDUSTRIAL APPLICABILITY The chicken breeding plant of the present invention processes chicken manure and supplies it to the breeding conveyor of the breeding apparatus. Therefore, the chicken manure collected from the breeding device does not contain chips and wood chips, and can be fermented and dried to be used as a high-quality organic fertilizer. Unlike conventional chicken manure containing chips and wood chips, it does not need to be incinerated and discarded, and can be reused effectively.

Further, the apparatus for breeding chickens by laying the treated feces on the breeding conveyor can prevent the production of a breast octopus as in the soil breeding. In addition, since the chicken eats calcium and the like contained in chicken droppings, it has the feature that high quality chickens can be raised.

Furthermore, the chicken breeding plant of the present invention has a feature that the number of breeding per unit area can be increased to prevent the occurrence of disease. This is because the dried treated feces are laid on the breeding conveyor, so that the chicken feces with a high water content can be dried quickly. That is, when the chicken droppings fall on the breeding conveyor, the treated droppings adhere to the surface thereof, and the attached treated droppings absorb water and are forced to dry.
Therefore, even if a large amount of chicken manure is discharged from the chicken, it is possible to keep the floor in a dry state and prevent the growth of bacteria.
Further, since the treated feces are supplied to the breeding conveyor, the cost does not increase even if a large amount is supplied, and the floor can be efficiently kept in a dry state.
