BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chicken manure drying device for a poultry house. More specifically, the present invention provides a plurality of long cage rows that are partitioned so as to accommodate an appropriate number of chickens in each compartment and are stacked back to back in a plurality of stages, and extend in the longitudinal direction below the cage rows in the longitudinal direction. The present invention relates to a poultry manure drying device for a poultry house, which has a moving belt for receiving poultry manure and dries poultry manure falling from a cage.

[0002]

2. Description of the Related Art A large-scale poultry raising facility in which a large number of chickens are stacked in a plurality of stages and housed in cages that are partitioned by forming long rows and the cage rows are arranged back to back Maintaining cleanliness and ensuring chicken health under good hygiene is a vital issue for poultry farmers. Therefore, various improvement measures have been proposed for ventilation in poultry houses and removal of chicken manure.

In order to remove chicken manure, it has been practiced to drop the manure directly from each cage under the floor to appropriately remove the manually deposited chicken manure. In recent years, however, each cage row is stacked in multiple stages. A belt conveyor for receiving chicken droppings is provided below the tray to drop the chicken droppings on it, and while the belt conveyor is moving, the chicken droppings are not fully dried with the belt so that they can be easily scraped off at the end of the belt conveyor. . However, since the chicken dung is not sufficiently dried, the belt conveyor is operated while the chicken dung is adhered to the belt, which is not hygienic. In order to perform this drying effectively, many drying devices have been proposed in which a cage is provided with a ventilation pipe to force ventilation to dry chicken droppings.

Among these drying devices, the device disclosed in US Pat. No. 5,007,379 by the present inventor is
A blower duct is formed in the longitudinal direction between the back-to-back cage rows, and a traction rope that can reciprocate over the entire length of the blower duct is provided. During the reciprocating motion of the tow rope, the wind is generated by rotating around the lateral axis of the top of the blower blade. The reciprocating movement of the tow rope is carried out by transmitting the rotational movement of the horizontal eccentric cam to one end thereof via a swing lever and by at least one compression spring surrounding the tow rope.

However, in this device, since a pulling rope or a pulling cable is used to drive the blower blade, a pulling force can be applied but a pressing force cannot be applied, so these pulling means are not used. A compression spring had to be used to move in the direction opposite to the pulling direction. Since the reciprocating motion of the traction means reaches 160 times per minute, damage to the compression spring due to fatigue is unavoidable, and generally one compression spring is provided for a cage length of 10 m, so in a large poultry house 100
It requires 200, 200 or more compression springs, which is noisy and the replacement and maintenance of these are very troublesome.

In order to eliminate these drawbacks, the inventor has previously shown that in an apparatus of the kind mentioned at the outset, an air duct is formed longitudinally between the cage rows of the back-to-back stages, with each stage being provided with an air duct. A rigid reciprocating rod capable of reciprocating motion is provided in the air passage over the entire length in the longitudinal direction, and a large number of air-blowing blades having a lateral axis at the top and arranged apart from each other penetrate below the lateral axis. When the reciprocating rod is reciprocated, the blower blade is attached so as to be rotatable about the lateral axis, and means for driving the reciprocating motion of the rigid reciprocating rod is provided for each rigid reciprocating rod. A patent application was filed for a poultry manure drying device for a poultry house, which has a vertical drive shaft for rotating a horizontal eccentric cam mechanically connected to one end of the rod (Japanese Patent Application No. 6-88461).

[0007]

Although this chicken dung drying apparatus using a rigid reciprocating rod is a significant improvement over the apparatus described in the above-mentioned US patent, it still has drawbacks. In other words, the poultry house has grown in size in recent years, so there is only one
There are some that are close to 00m, and even more than 100m in some cases. In such a long cage row, although it is rigid, there is a limit to driving the reciprocating rod by the traction force and pressing force at only one end, and it may be difficult to blow air efficiently and reliably. Came. An object of the present invention is to provide an apparatus capable of sufficiently drying chicken droppings accumulated on a belt conveyor under a ventilation path even in a long cage row.

[0008]

In order to achieve this object, a poultry drier drying apparatus for a poultry house according to an embodiment of the present invention comprises:
A long cage row partitioned so as to accommodate an appropriate number of chickens in each compartment is provided in a back-to-back stack of multiple stages, and below the cage row is a longitudinally extending and longitudinally moving chicken droppings receiving tray. It has a belt conveyor and dries chicken droppings falling on the belt conveyor from the cage, and an air passage is formed in the longitudinal direction between the cage rows of each of the back-to-back stages. A possible rigid reciprocating rod is provided over the entire length in the longitudinal direction, and a number of fan blades having a transverse axis at the top and arranged at a distance from each other are provided on the reciprocating rod penetrating below the transverse axis. In the poultry manure drying device of a poultry house, wherein the blower blades are mounted so as to be rotatable around the lateral axis when the reciprocating rod is reciprocated, the rigid reciprocating rod has two reciprocating portions substantially at the center of the length of the air duct. Divided into two by the rod A reciprocating motion driving means of a rigid reciprocating rod divided into two is provided, and the driving means has two discs arranged in parallel to the longitudinal direction of the air duct so as to partially overlap with each other by deviating the centers. , The opposite ends of the halved rigid reciprocating rod are mechanically connected to opposite peripheral edges of the two discs, and the two discs are the centers of imaginary circles circumscribing both discs. It is characterized by the same circular motion around the axis without rotating itself. According to another embodiment of the present invention, the reciprocating motion driving means of the rigid reciprocating rod is
It is possible to have two vertical drive shafts for respectively rotating two horizontal eccentric cams mechanically connected to opposite ends of each rigid reciprocating rod.

[0009]

As described above, the chicken manure drying apparatus according to the present invention bisects the rigid reciprocating rod at about the center of the length of the air duct and the driving means for the reciprocating rod at the middle thereof. Since the length of the reciprocating rod to be pressed is about 1/2, it can be used without trouble even in a long cage row. The driving means for alternately applying a traction force and a pressing force to the reciprocating rod has, for example, at least two types of configurations as described above, and has an effect that a sufficient driving force can be applied to the reciprocating rod.

[0010]

EXAMPLE Since the chicken manure drying apparatus according to the present invention is bisected approximately at the center in the longitudinal direction of the cage row and is symmetrically arranged, in FIGS. 1 and 6, only the left half is mainly shown. Will be explained. The components on the right half of the figure are distinguished by adding a dash to the same numbers as on the left half. In the left-half cage shown in FIGS. 1 and 2, the long cage row 1 is stacked in three stages,
These rows are arranged back to back. Below each cage row 1, a belt conveyor 2 for transferring chicken droppings 2 ′ falling from the cage in the direction of the arrow is provided over the entire length of the cage row without being divided into two at the center. The bottom of the cage is composed of a lattice floor 3 forming an inclined surface for eggs, and a bait gutter 4 is attached to the front surface. A water supply pipe 5 is provided above the longitudinal center vertical plane of each back-to-back cage row 1.
A water receiver 6 is provided below it.

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

A metal rigid reciprocating rod 14 is provided in the upper part of the air passage 8 along a longitudinal center vertical plane over the entire length of the air passage 8 and thus of the left cage row, the left end of which is not shown. It is supported by the end member of the blower duct 8. As shown in FIGS. 3 and 5, the reciprocating rod 14 (1
4 ') is a large number of blower blades 1 which are arranged apart from each other.
5 is attached by penetrating an opening 17 provided in the upper portion thereof. A lateral axis 16 is provided at the top of the blower blade 15 so that the blower blade 15 is attached to the inner wall surface of the blower passage 8. The attachment of the blower blades 15 to the reciprocating rods 14 is carried out laterally of the top of the opening 17 in the upper part of the blower blades so that the blower blades 15 can rotate in the blower passage 8 about the lateral axis 16 when the reciprocating rods 14 reciprocate. The reciprocating rod 14 is fixed to the fixture 18 attached to the direction rotation shaft. The blower blades 15 thus attached to the reciprocating rod 14 leave a slight gap between them and the inner wall surface of the blower passage 8. If the reciprocating rod 14 is moved to the left in FIG. If the reciprocating rod 14 is moved to the right and then the reciprocating rod 14 is moved to the right, the blower blade 15 is moved to the right. As described above, the attachment of the blower blade 15 to the reciprocating rod 14 is performed by the blower blade 1
The fixture 1 is provided at a position near the lateral axis 16 which is the center of rotation of the gear 5.
Since it is performed by 8, the blower blade 15 can be rotated by increasing the relatively small reciprocating motion of the reciprocating rod.

Next, one embodiment of a mechanism for driving the reciprocating motion of the halved reciprocating rods 14 and 14 'will be described. The right end portion 19 of the left reciprocating rod 14 projects outward from the end portion of the cage row 1 and is arranged in parallel with the longitudinal direction of the air passage 8 so as to partially overlap with each other by offsetting the centers. It is mechanically connected to the peripheral portion of one (left side) 20 of the plates 20, 20 'via a crank 22 as shown in FIG. 4, for example. The two discs 20 and 20 'move circularly around a virtual circle circumscribing both discs in the same direction at the same speed as shown by arrows in FIGS. 1 and 4, without rotating themselves. This circular movement is converted into reciprocating movement through the crank 22, and reciprocating rods 14 and 14 'are given traction force and pressing force to reciprocate them in the arrow direction. The circular movement of the discs 20, 20 'is driven by, for example, an electric motor, and is performed via an eccentric cam (not shown) having a diameter smaller than that of the discs 20, 20' having a central axis 21 as a rotation axis.

As the reciprocating motion driving means for the reciprocating rods 14 and 14 ', a horizontal eccentric cam used in the chicken dung drying apparatus of Japanese Patent Application No. 6-88461 as shown in FIG. It can also be used. Left return rod 14
The right end portion 19 of the eccentric cam is connected via one of the two horizontal eccentric cams (left side) 24 fixedly attached to one (left side) 23 of two vertical drive shafts driven by a motor. It is mechanically connected to the peripheral portion of a disc (not shown) having a diameter larger than that of an eccentric cam that is circularly moved about a rotation axis, for example, via a crank (not shown). As a result, the eccentric cam 24 rotates together with the vertical drive shaft 23 while being mechanically connected to the end portion 19 and causes the circular plate to move circularly. Therefore, the rotary motion is converted into a reciprocating motion to move the reciprocating rod 14 in the arrow direction. It can be reciprocated. However, in the case of this embodiment, the vertical drive shafts 23, 23 'penetrate through each stage of the cage row, so that there is a disadvantage in that the belt conveyor 2 for transferring poultry manure is divided into two. In the case of this embodiment, when the reciprocating rod is attached to the eccentric cam, the phase is changed for each stage of each cage row (for example, in the case of three rows of cages, 120 degrees in the disc rotation direction, respectively). It can be attached to the vertical drive shaft 23 to increase its effect and prevent the cage row from swaying due to simultaneous reciprocating movements of the reciprocating rods 14 and 14 'in the same phase.

[0015]

The chicken droppings drying apparatus for a poultry house according to the present invention divides the rigid reciprocating rod 14 that rotatably moves the blower blades 15 for actually feeding new air into the cage row 1 into two at approximately the center of the cage row. By using the reciprocating rods 14 and 14 'of a book, it becomes possible to give a sufficient driving force to the reciprocating rods 14 and 14' even in a long cage row, and it is possible to effectively dry chicken droppings.
