DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chicken dung drying apparatus for a poultry house. More specifically, the present invention is characterized in that a long row of cages partitioned so as to accommodate an appropriate number of chickens in each section is provided in a plurality of layers back to back, and extends below the cage row in the longitudinal direction and extends in the longitudinal direction. The present invention relates to a poultry manure drier having a belt conveyor for receiving moving poultry manure and drying chicken poultry falling from a cage together with the belt while moving.

[0002]

2. Description of the Related Art In a large-scale poultry farming facility in which a large number of chickens are stacked in a plurality of stages and housed in cages that are partitioned in long rows and the cage rows are arranged back to back, the interior of the poultry house is Keeping chickens clean and under good hygiene is a very important issue for poultry farmers. Therefore, various improvement measures have been proposed for ventilation and removal of poultry manure in the poultry house.

[0003] In order to remove chicken dung, it has been practiced to drop the dung directly from each cage under the floor and remove the chicken dung that has been deposited manually as appropriate. A belt conveyor for receiving chicken dung is provided below, and chicken dung is dropped on it. The belt conveyor does not move during the drying of the chicken dung, for example, after three days of drying, the belt conveyor is moved and scraped at the end of the belt conveyor. Easy to do. However, if the chicken dung is not sufficiently dried, the belt conveyor is operated while the chicken dung is adhered to the belt, which is not preferable for hygiene. In order to perform this drying effectively, many drying apparatuses have been proposed in which a blower tube is provided in a cage to forcibly ventilate and dry chicken dung.

Among these drying apparatuses, the apparatus disclosed in US Pat. No. 5,007,379 by the present inventor is:
A blower duct is formed longitudinally between the back-to-back cage rows, and a traction rope that can reciprocate over the entire length of the blower pipe is provided. During the reciprocating movement of the towing rope, the wind is generated by rotating about the horizontal axis at the top of the blower wing. The reciprocating movement of the traction rope is performed by transmitting the rotational movement of the horizontal eccentric cam to one end thereof via a swinging lever, and by at least one compression spring surrounding the traction rope.

[0005]

However, since the device disclosed in the above-mentioned U.S. Patent uses a traction rope or a traction cable to drive the blower blades, it can apply a pulling force, but can apply a pressing force. Therefore, it is necessary to use a compression spring to move these traction means in the direction opposite to the driving direction of the tension by the eccentric cam. The reciprocating movement of the traction means is 16 times per minute.
Because it reaches zero times, damage to the compression spring due to fatigue is inevitable.
Since a large number of compression springs are provided, a large poultry house requires 100, 200 or more compression springs, and their replacement and management are very troublesome. An object of the present invention is to provide an improved chicken dung drying apparatus which eliminates such disadvantages of the prior art.

[0006]

In order to achieve this object, a poultry manure drier for a poultry house according to the invention is provided, in an apparatus of the type mentioned at the outset, in which the air duct is extended longitudinally between the rows of cages in each back-to-back stage. In the air passage of each stage, a reciprocating rigid reciprocating rod is provided over the entire length in the longitudinal direction, and a large number of air blowing blades having a horizontal axis at the top and arranged apart from each other, The blower blade is attached to the reciprocating rod penetrating below the horizontal axis so that the blower blade can rotate about the horizontal axis when the reciprocating rod reciprocates, and drives the reciprocating motion of the rigid reciprocating rod. The means is a vertical drive shaft for rotating a horizontal eccentric cam mechanically connected to one end of each rigid reciprocating rod. According to one embodiment of the present invention, a horizontal axis of a fixture for attaching the blower blade to the reciprocating rod is disposed parallel to and below the horizontal axis of the top of the blower blade at an opening at an upper portion of the blower blade, and By the rod reciprocating through the opening, the blower blade can be given a movement in the same direction as the reciprocating rod.

According to another embodiment of the present invention, the air passage is divided by two parallel wall surfaces forming a rear wall of the cage row, and a small gap is provided between each of the air blow blades disposed therein. An air inlet on the upper surface of the air duct and an air outlet on the lower surface by bending the upper end of each wall of the air duct inward and bending the lower end of each wall outward. Is formed. According to yet another embodiment,
A horizontal eccentric cam attached to the vertical drive shaft is attached to the rigid reciprocating rod of each stage with a different phase.

[0008]

According to the chicken dung drying apparatus of the present invention, not only the pulling force but also the pressing force can be exerted by using the rigid reciprocating rod instead of the conventional traction means as described above. No longer required.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the illustrated cage, long rows of cages 1 are stacked in three rows, and these rows are arranged back to back. Below each row of cages 1, there is provided a belt conveyor 2 for transporting chicken dung 2 'falling from the cages in the direction of the arrow. The bottom of the cage is constituted by a lattice floor 3 forming an inclined surface for eggs, and a bait gutter 4 is attached to the front. A water supply pipe 5 is provided above a vertical central vertical plane of each back-to-back cage row 1, and a water receiver 6 is provided below it.

On both sides of the central vertical plane, two parallel walls 7 forming the rear wall of each cage row extend in the longitudinal direction over the entire length of the cage row, and an air duct 8 To form The upper end 9 of the wall 7 located below the water receiver 6 is bent inward, while the lower end 10 of the wall 7 located below the grid floor 3 is bent outward to provide an air inlet 11 and an air outlet, respectively. 12 are formed on the upper and lower surfaces of the air duct 8 along the longitudinal direction. Below the air outlet 12, an air flow dividing plate 13 is provided.

A metal reciprocating rod 14 is provided at an upper portion of the air duct 8 along a vertical center plane in the longitudinal direction.
Therefore, it is provided over the entire length of the cage row, and both ends thereof are supported by end members of the blower duct 8 (not shown). The reciprocating rod 14 has a large number of blower blades 15 spaced apart from each other, and an opening 17 provided at an upper portion thereof.
Is mounted through the. A transverse axis 16 is provided at the top of the blower blade 15, whereby the blower blade 15 is mounted on the inner wall surface of the blower duct 8. The blower blade 15 is attached to the reciprocating rod 14 so that the blower blade 15 can rotate around the horizontal axis 16 in the blower duct 8 when the reciprocating rod 14 reciprocates. The reciprocating rod 14 is fixed to a fixture 18 attached to the horizontal rotation shaft. Thus reciprocating rod 1
Blower blades 15 attached to the 4 is leaving a slight gap between the inner wall of the air conduit 8, the reciprocating rod 14 blower blades 15 By moving the left towards the Figure 1 towards the left If it moves and then the reciprocating rod 14 is moved to the right , the blower wing 15 will move to the right .

Next, a mechanism for driving the reciprocating motion of the reciprocating rod 14 will be described. One end 19 of the reciprocating rod 14 protrudes outside from the end of the cage row 1, and a vertical drive shaft 21 provided with a driving means such as a motor 20 is provided near the end 19. I have. This vertical drive shaft 21 includes
A horizontal eccentric cam 22 is fixedly mounted so that it cannot rotate with the shaft 21 while being mechanically connected on the one hand to the end 19 of the reciprocating rod 14 via a crank (not shown). As a result, the eccentric cam 22 rotates together with the vertical drive shaft 21 while being mechanically connected to the end portion 19, so that the rotational motion is converted into a reciprocating motion and the reciprocating rod 14 reciprocates in the direction of the arrow.

At the time of mounting, the horizontal eccentric cam 22 is mounted on the vertical drive shaft 21 by changing the phase of each reciprocating rod 14 (for example, in the case of three reciprocating rods, each is shifted by 120 ° in the rotational direction). Thus, since the rotating motion of the blower wings 15 attached to the reciprocating rods 14 is performed with a phase difference from each other, it is possible to further contribute to the blowing effect in the poultry house and thus to the drying effect of chicken dung.

[0014]

The poultry manure drying apparatus according to the present invention uses a material having rigidity such as metal for the reciprocating rod 14 for rotating the blower blades 15 for actually feeding new air into the cage row 1. By doing so, it was possible to overcome the drawbacks of the conventional compression spring, which is a consumable part, requires replacement , and generates noise . In addition, reciprocating rod 1
4. The drying air blowing mechanism having the air blowing blades 15 is housed in the air blowing line 8 formed by the rear wall 7 of each cage row, and the vertical drive shaft 21 is provided with the horizontal eccentric cam 22 for each reciprocating rod 1.
The above-mentioned effect can be further enhanced by providing a phase difference for every 4 and mounting. Further blower wing 15
Is attached to the reciprocating rod 14 at the rotation center of the blower blade 15.
At a location close to the transverse axis 16
Therefore, the relatively small reciprocating motion of the reciprocating rod is increased to
15 could be rotated.
