Description

Conveyor for poultry farm and method of use thereof

The present invention relates to a conveyor for transporting chicken manure and eggs in poultry farming facilities, and a method for using the conveyor.

In large-scale poultry farms, there are belt conveyors for transporting caged bird excrement (chicken manure), plate conveyors for transporting and drying chicken manure, and eggs produced by caged birds. Various conveyors are used, such as bar conveyors, for conveying. These conveyors may be arranged such that the transport path formed by the conveyor passes through spaces defined by walls. In other words, there are cases where the conveying path by the conveyor is used so as to pass through the opening provided in the wall.

In such cases, it is desirable that this opening is not open when the conveyor is not in use. In particular, in the case of an opening provided in a wall that separates the interior space and the exterior space of a building, there is a high possibility that foreign objects such as dust and small animals will enter the building through the opening.

Therefore, the present applicant has already proposed a shutter device capable of opening and closing the space above the conveying path at the opening provided in the wall when the bar conveyor passes through the opening (Patent Document 1). This closes the space above the conveying path at the opening by inserting a shutter between two adjacent bars on the bar conveyor. That is, the shutter device of Patent Document 1 is exclusively for bar conveyors.

However, as described above, conveyors that are used in poultry farms so that the transport path passes through openings provided in the wall are not limited to bar conveyors. Therefore, there has been a demand for a conveyor that can prevent foreign objects and small animals from entering through openings provided in walls, regardless of the type of conveyor.

Japanese Patent No. 6472542

Therefore, in view of the above-mentioned actual situation, the present invention prevents foreign objects and small animals from entering through openings regardless of the type of conveyor used so that the conveying path passes through openings provided in the wall in poultry farms. The object is to provide a conveyor that can

In order to solve the above problems, the conveyor for poultry farming facilities according to the present invention includes:
"A conveyor for conveying an object to be conveyed from a first space partitioned by a wall to a second space in a poultry farm facility through an opening provided in the wall,
a conveyor frame supporting the conveying components;
a plurality of rollers carrying a conveyor frame;
a rotatable long screw shaft having a male screw formed on its outer peripheral surface and supported so that its axial direction is parallel to the conveying direction of the conveyor;
a nut having a female thread that is threadedly engaged with the male thread;
a nut fixing portion to which the nut is fixed and which is fixed to the conveyor frame;
When the long screw shaft is rotated while the roller is rotatable, the nut whose rotation is restricted by the nut fixing portion moves in the axial direction of the long screw shaft, and the force for moving the nut is the By being transmitted to the conveyor frame through the nut fixing portion, the conveyor frame moves in the front-rear direction.

"Conveyance direction" is the direction in which the object to be conveyed faces, and is synonymous with "forward direction". The direction opposite to the forward direction is the "rear direction", and the forward direction and the rearward direction are collectively referred to as the "front-rear direction".

The type of conveyor to which the present invention is applied is not particularly limited, and can be belt conveyors, chain conveyors, roller conveyors, and screw conveyors. In the case of a belt conveyor, the conveying path constituent members are mainly composed of a pair of pulleys, an endless belt wound around the pair of pulleys, and a driving mechanism for driving circulation of the endless belt. In the case of a chain conveyor, the conveying path constituent members are two endless chains that are wound around a pair of sprockets and circulate, and a conveyed object such as a bar, plate, or bucket that is supported by the two endless chains. The main components are an object holding part and a driving mechanism for driving circulation of the endless chain.

In the case of a roller conveyor, the conveying path constituent members are mainly free rollers arranged in the conveying direction and rotated by the weight of the object to be conveyed, or rollers arranged in the conveying direction and rotated by a drive mechanism. configuration. In the case of a screw conveyor, the conveying path constituting member is mainly composed of a screw that turns spirally and extends in the conveying direction, and a driving mechanism that drives the rotation of the screw.

The male screw portion of the long screw shaft and the female screw of the nut may be screwed together by direct contact, or the male screw and the female screw may be screwed together via a ball. . Moreover, the cross-sectional shape of the "screw" in the male thread and the female thread is not particularly limited, and can be trapezoidal, square, rectangular, or triangular.

With the conveyor of this configuration, the entire conveyor frame that supports the transport path constituent members can be moved back and forth by a simple operation of rotating the long screw shaft. That is, the nut for screwing the female screw onto the male screw of the long screw shaft is fixed to the nut fixing portion, and the nut fixing portion is fixed to the conveyor frame. Therefore, when the long screw shaft is rotated, the nut moves in the axial direction of the long screw shaft without rotating. The axial direction of the long screw shaft is parallel to the conveying direction. Therefore, the force for moving the nut is transmitted to the conveyor frame via the nut fixing portion, and the force for moving the nut in the front-rear direction acts on the conveyor frame.

The conveyor frame that supports the transport path components is extremely heavy, but the conveyor frame is placed on multiple rollers. Therefore, since these rollers are rotatable, when a force for moving the conveyor frame in the front-rear direction is applied, the heavy conveyor frame can be moved in the front-rear direction by this force.

The conveyor of the present invention, which can move the entire conveyor frame in the front-rear direction, has a conveying path passing through an opening provided in a wall that separates the first space and the second space. While conveying objects from the first space to the second space, the entire conveyor can be retracted into the first space when the conveyor is not in use. Therefore, regardless of the type of conveyor, the opening in the wall can be completely closed when not in use, preventing foreign matter and small animals from entering from one of the first space and the second space to the other through the opening. can be reliably prevented.

In addition to the above configuration, the conveyor for poultry farming facilities according to the present invention includes:
"The plurality of rollers each have a uniform diameter portion on which the conveyor frame is placed, and the diameter gradually increases outward from the same diameter portion in the left-right direction perpendicular to the front-rear direction. "has an enlarged diameter".

In this configuration, when the conveyor frame is moved in the front-rear direction, the presence of the enlarged diameter portion prevents the movement direction of the conveyor frame placed on the same diameter portion of the roller from shifting to the left or right. As a result, the conveyor frame can be prevented from meandering and moved forward and backward correctly.

Next, the method of using the conveyor for poultry farming facilities according to the present invention is as follows:
"a conveyor frame supporting the conveying components;
a plurality of rollers carrying a conveyor frame;
a rotatable long screw shaft having a male screw formed on its outer peripheral surface and supported so that its axial direction is parallel to the conveying direction of the conveyor;
a nut having a female thread that is threadedly engaged with the male thread;
a nut fixing portion to which the nut is fixed and which is fixed to the conveyor frame;
Placed in the first space separated from the second space by a wall in the poultry farm,
The long screw shaft is rotated while the roller is rotatable, and the nut, whose rotation is restricted by the nut fixing portion, is moved in the axial direction of the long screw shaft. By transmitting to the conveyor frame through the portion, the conveyor frame is moved in the front-rear direction,
When conveying an object to be conveyed by the conveyor, the force for moving the object in the forward direction is transmitted to the conveyor frame, and the vicinity of the end portion of the conveyor is conveyed through the opening penetrating the wall. enter into the second space;
When the conveyor is not in use, a force for moving the conveyor in the rearward direction is transmitted to the conveyor frame to draw the vicinity of the end of the conveyor from the second space into the first space;
closing said opening."

This is how the conveyor for the poultry farming facility mentioned above is used.

INDUSTRIAL APPLICABILITY As described above, according to the present invention, foreign objects and small animals can be prevented from entering through openings regardless of the type of conveyor used in poultry farms so that the conveying path passes through openings provided in the walls. A conveyor and a method of using the conveyor can be provided.

Hereinafter, a conveyor 1 for a poultry farming facility, which is a specific embodiment of the present invention, and a method of using the same will be described with reference to the drawings. Here, the case where the conveyor 1 is a belt conveyor is illustrated.

The conveyor 1 includes a conveyor frame 10, a conveying path component supported by the conveyor frame 10, rollers 20 on which the conveyor frame 10 is placed, roller supports 30 that rotatably support the rollers 20, and and a feeding device 40 for transmitting a moving force to the conveyor frame 10. - 特許庁

The conveyor frame 10 includes two side frames 11 separated in the left-right direction, and a horizontal connecting member 12 connecting the side frames 11 to each other. Here, the "horizontal direction" is a horizontal direction orthogonal to the front-rear direction.

Each of the side frames 11 includes a long upper bar 11a and a lower bar 11b extending in the conveying direction, and a plurality of longitudinal connecting members 11c connecting the upper bar 11a and the lower bar 11b. The horizontal connecting member 12 connects the lower bar 11b of the left side frame 11 and the lower bar 11b of the right side frame 11 at multiple points.

The conveyor frame 10 supports the conveying path constituent members between the left and right side frames 11 above the horizontal connecting member 12 . In the present embodiment, the conveying path constituent members are mainly composed of a pair of pulleys, an endless belt wound around the pair of pulleys, and a drive mechanism for driving circulation of the endless belt (both are not shown in the drawing). omit). One of the pair of pulleys is rotatably supported by the conveyor frame 10 near its forward end, and the other pulley is rotatably supported by the conveyor frame 10 near its rearward end. In addition, the conveyor 1 includes carrier rollers 68 that support the upper belt of the circulating endless belt that conveys the object to be conveyed, and return rollers 69 that support the lower (return side) belt, as members constituting the conveying path. . Both the carrier roller 68 and the return roller 69 are rotatably supported between the left and right side frames 11 via a vertical connecting member 11c. In FIG. 1, in order to clearly show the rollers 20, illustration of some of the return rollers 69 is omitted.

The rollers 20 are used as free rollers, and are provided with a plurality of pairs of rollers 20 forming a pair on the left and right per one conveyor. Each of the rollers 20 of this embodiment has a same-diameter portion 21 having a uniform diameter and an enlarged-diameter portion 22 connected to the same-diameter portion 21 and gradually increasing in diameter.

The roller support parts 30 are parts that support the rollers 20 forming a pair on the left and right, and are provided for the number of pairs of the rollers 20 per conveyor. Each roller support portion 30 has a base portion 31 and a roller fixing portion 32 . The base portion 31 is an elongated rod-like member and has two pieces, each extending in the left-right direction, and placed on the installation surface 91 such that the two pieces are separated in the transport direction. The distance between the two base portions 31 is set slightly larger than the diameter of the enlarged diameter portion 22 of the roller 20 .

Two roller fixing portions 32 are provided corresponding to the number of rollers 20 per roller supporting portion 30 . Each roller fixing portion 32 includes a bridge portion 32a spanning two spaced apart base portions 31 and a rotation shaft support portion 32b extending into the space between the two base portions 31. have. The bridge portion 32a is a flat plate having a square hole portion 32h extending therethrough, and both ends of the bridge portion 32a are fixed to the base portion 31 while being placed on the upper surface of the base portion 31, respectively. In the bridge portion 32a, flat plate-like rotation shaft support portions 32b extend downward from a pair of sides parallel to the conveying direction of the periphery of the hole portion 32h. A roller 20 is disposed between these two rotating shaft supporting portions 32b, and both ends of the rotating shaft 20p are rotatably attached to the rotating shaft supporting portions 32b so that the direction of the rotating shaft 20p of the roller 20 is the horizontal direction. It is

In addition, the roller 20 is rotated at a height where there is a gap h between its lower end and the mounting surface and the upper portions of the same diameter portion 21 and the enlarged diameter portion 22 are exposed above the hole 32h. It is attached to the shaft support portion 32b (see FIG. 4).

The lower bar 11b of the conveyor frame 10 is placed on the same diameter portion 21 of the portion of the roller 20 exposed above the hole 32h. Accordingly, the fixed positions of the roller fixing portions 32 with respect to the base portion 31 are adjusted such that the left and right rollers 20 in one roller support portion 30 are separated by the distance between the left and right side frames 11 . Further, the left and right rollers 20 are fixed in such a direction that the same diameter portion 21 is inside in the left-right direction and the enlarged diameter portion 22 is outside.

The feeding device 40 includes a long screw shaft 41 , a nut 42 , a nut fixing portion 43 , a tool locking portion 45 and a screw base portion 47 . The screw base portion 47 supports the long screw shaft 41 so that the height from the installation surface 91 is higher than the upper end of the roller 20 . In this embodiment, the screw base portion 47 is supported by the installation surface 91 via one of the roller support portions 30 . Specifically, the screw base portion 47 has a flat bottom portion 47a and a pair of support pieces 47b that stand upward from both ends of the bottom portion 47a. The bottom surface portion 47a is bridged over the two base portions 31 at a position where it does not interfere with the portion of the roller 20 exposed upward from the hole portion 32h.

The long screw shaft 41 has a male screw 41a formed on the outer peripheral surface of the shaft, and both ends thereof are fixed to support pieces 47b via bearings 47c, respectively, so that the axial direction is parallel to the conveying direction. It is rotatably supported between the pair of support pieces 47b so as to be. One end of the long screw shaft 41 extends outside the bearing 47c, and a tool locking portion 45 is provided there.

The tool locking portion 45 is a polygonal columnar portion that locks a tool for rotating the long screw shaft 41 . Here, the case where the tool locking portion 45 has a hexagonal columnar shape is illustrated. As a configuration for rotating the tool locking portion integrally with the long screw shaft, a female screw is provided in the tool locking portion, the female screw is fastened to the male screw of the long screw shaft, and the long screw shaft It is conceivable that the tool locking portion is fixed with respect to. However, in that case, by repeatedly applying torque to the tool locking portion to rotate the long screw shaft, the male thread of the long screw shaft and the female thread of the tool locking portion are crushed, and the tool locking portion is damaged. may not be able to be removed from the long screw shaft. It is desirable that the tool locking portion be replaceable in order to maintain a good locking state with the tool.

Therefore, in this embodiment, the following configuration is adopted in order to integrally rotate the tool locking portion 45 with the long screw shaft 41 . That is, the end portion of the long screw shaft 41 on the side where the tool locking portion 45 is attached is a non-threaded portion 41b having no external thread, and a concave portion 41r is formed therein. A key 44 is fitted into the recess 41r so as to protrude from the outer peripheral surface of the non-threaded portion 41b. On the other hand, the tool locking portion 45 has a through hole 45h for inserting the unthreaded portion 41b, and a slit 45s parallel to the through hole 45h. The slit 45s penetrates the tool locking portion 45 while opening on the inner peripheral surface of the through hole 45h. The width of the slit 45s is set to be slightly larger than the width of the key 44, and the depth of the slit 45s is set to be slightly larger than the height at which the key 44 protrudes from the outer peripheral surface of the unthreaded portion 41b. With such a configuration, when the non-threaded portion 41b is inserted into the through hole 45h with the key 44 fitted in the recess 41r, the projecting portion of the key 44 is inserted into the slit 45s. That is, a part of the key 44 is fitted into the concave portion 41r of the long screw portion 41, and the rest of the key 44 is inserted into the slit 45s of the tool locking portion 45. As shown in FIG. As a result, when the tool locking portion 45 is rotated using a tool, the long screw shaft 41 is integrally rotated.

In addition, the tool locking portion 45 has a female screw hole 45f which is orthogonal to the axial direction, one end of which is open to the outer peripheral surface and the other end of which communicates with the through hole 45h. The set screw 46 is inserted into the female screw hole 45f, and the unthreaded portion 41b inserted into the through hole 45h is pressed by the tip of the set screw 46, whereby the long screw portion 41 integrated via the key 44 is pressed. and the tool locking portion 45 are prevented from rattling. Here, although a set screw 46 having a hexagonal hole 46e at the end and being advanced and retracted with a hexagonal wrench is illustrated, a set screw with a slot can also be used.

The female thread of the nut 42 is screwed into the male thread 41 a of the long screw shaft 41 . The nut 42 is screwed onto the long screw shaft 41 between the pair of support pieces 47b. Also, the nut 42 has a flange portion 42f at one end.

The nut fixing portion 43 has a flat plate shape, and the long screw shaft 41 is passed through between one of the support pieces 47b and the nut 42. The nut 42 is fixed to the nut fixing portion 43 with the flange portion 42f superimposed on the nut fixing portion 43 . An end portion of the nut fixing portion 43 is fixed to one vertical connecting portion 11 c of the side frame 11 . That is, the nut 42 is fixed to the nut fixing portion 43 and the nut fixing portion 43 is fixed to the conveyor frame 10 .

The conveyor 1 with the above configuration can be used in a very novel way, in which the conveyor frame 10 that supports the transport path components, which is extremely heavy, is entirely slid on the installation surface 91.

Specifically, when the tool locking portion 45 is rotated using a tool such as a wrench, the long screw shaft 41 rotates together with the tool locking portion 45 . The female screw of the nut 42 is screwed into the male screw 41a of the long screw shaft 41, but the nut 42 is fixed to the nut fixing portion 43, and the nut fixing portion 43 is fixed to the conveyor frame 10. , the nut 42 moves in the axial direction of the long screw shaft 41 as the long screw shaft 41 rotates without rotating. At that time, the force that moves the nut 42 in the axial direction is transmitted to the conveyor frame 10 via the nut fixing portion 43 .

The conveyor frame 10 is placed on a plurality of rollers 20 , and the rollers 20 are rotatably supported at a height with a gap h between them and the installation surface 91 . Moreover, the direction of the rotating shaft 20p of the roller 20 is the horizontal direction. In other words, the rolling direction of the rollers 20 relative to the conveyor frame 10 is the front-back direction. Therefore, the force transmitted from the nut 42 to the conveyor frame 10 via the nut fixing portion 43 causes the conveyor frame 10 to move forward and backward while rotating the rollers 20 . Forward rotation of the long screw shaft 41 moves the conveyor frame 10 forward, and reverse rotation of the long screw shaft 41 moves the conveyor frame 10 backward.

Therefore, the first space S1 and the second space S2 are partitioned by the wall 92, and the conveyed object is conveyed by the conveyor 1 from the first space S1 to the second space S2 through the opening 92h provided through the wall 92. In this case, as shown in FIG. 3(A), the conveyor frame 10 of the conveyor 1 arranged in the first space S1 is moved forward to allow the vicinity of the front end of the conveyor 1 to pass through the opening 92h. It can be made to enter two spaces S2. As a result, the conveyed object conveyed in the first space S1 by the conveyor 1 can be transferred to another conveyor in the adjacent second space S2 to continue conveying, or the conveyed object can be conveyed in the first space S1 by the conveyor 1. The conveyed objects can be discharged from the conveyor 1 in the adjacent second space S2 and introduced into a collection container.

On the other hand, when the conveyor 1 is not in use, the entire conveyor 1 is drawn into the first space S1 by moving the conveyor frame 10 backward, as shown in FIG. 3(B). The opening 92h can be completely closed with a door 93. As a result, foreign objects and small animals can be prevented from entering from one of the first space S1 and the second space S2 to the other through the opening 92h.

In particular, when the first space S1 is the interior space of the building and the second space S2 is the exterior space, if the opening 92h is open even when the conveyor 1 is not in use, the flow from the exterior space to the interior space will flow through the opening 92h. There is a high possibility that foreign objects or small animals will enter, and the resulting problems are serious.

As described above, according to the conveyor 1 of the present embodiment, the entire conveyor frame 10 supporting the transport path constituent members can be moved in the front-rear direction by a simple operation of rotating the long screw shaft 41. .

In addition, since the conveyor frame 10 is placed on a plurality of rotatable rollers 20, resistance is small when a force is applied to move the conveyor frame 10 in the front-rear direction. Therefore, even if the torque for rotating the long screw shaft 41 is small by a manual tool, it is possible to move the conveyor frame 10 that supports the conveying path constituent members, which is extremely heavy.

In addition, the conveyor frame 10 is placed on the same diameter portion 21 of each of a plurality of rollers 20, and the roller 20 has an enlarged diameter portion 22 whose diameter gradually increases outside the same diameter portion 21 in the left-right direction. ing. Therefore, when the conveyor frame 10 is moved in the front-rear direction, the presence of the expanded diameter portion 22 prevents the movement direction from shifting leftward and rightward. As a result, the conveyor frame 10 can be prevented from meandering and moved forward and backward correctly.

Although the present invention has been described above with reference to preferred embodiments, the present invention is not limited to the above embodiments, and various improvements and design changes are possible without departing from the scope of the present invention. is.

For example, in the above embodiment, the screw fixing portion 47 that rotatably supports the long screw shaft 41 is supported by the installation surface 91 via one of the roller support portions 30 . The configuration is not limited to this, and a configuration in which the fixing portion for screws is directly supported on the installation surface may be employed.

When the conveyor frame 10 is moved back and forth, the rollers 20 on which the conveyor frame 10 is placed must be rotatable. 1, the rotation of the roller 20 may be regulated by a stopper while the object to be conveyed is being conveyed.
