Installation structure of the shutter device and the shutter device

Abstract

The downstream end of the first conveyor (C1) penetrating the wall opening (A1) is inserted into the box body (10) from the side opening (A2), and the upstream end of the second conveyor (C2) is positioned below the box body (10). Since the wall opening (A1) and the side opening (A2) are connected by a covering, when the object to be transported is not transferred from the first conveyor (C1) to the second conveyor (C2), the wall opening (A1) can be closed by closing the bottom surface of the box body (10) with a shutter plate (30).

Description

Technology Field

[0001] The present invention relates to an installation structure for a shutter device and a shutter device, wherein a shutter device for opening and closing a wall opening is installed near a wall opening through which a conveyor passes. Background Technology

[0002] In large-scale poultry facilities, various conveyors are used, such as belt conveyors for transporting chicken manure from caged chickens, plate conveyors for transporting and drying the manure, and bar conveyors for transporting eggs produced by caged chickens. These conveyors are sometimes arranged to pass through multiple spaces partitioned by walls. In other words, conveyors are used to penetrate openings formed in the walls.

[0003] In such cases, it is desirable to close the wall opening when the conveyor is not in use (when the conveyor is stopped). In particular, in the case of openings formed in walls separating the interior and exterior spaces of a building, there is a high risk that small animals such as rats may enter the building through the wall opening; therefore, it is highly necessary to close the wall opening when the conveyor is not in use.

[0004] Therefore, the present applicant has proposed a number of shutter devices capable of opening and closing a wall opening when a conveyor passes through the wall opening (see Patent Documents 1 to 3). Patent Documents 1 and 2 position a shutter device in a wall opening through which a bar conveyor passes, and close the space above the conveyor bar in the wall opening by inserting a plate-shaped shutter from above between adjacent bars in the bar conveyor.

[0005] In the invention of Patent Document 3, a frameless space is created in a part of the frame of a belt conveyor where there are no side bars and only an endless belt exists. Then, the belt conveyor is positioned so that the frameless space is adjacent to a wall opening, and a shutter device having upper and lower shutters is installed in the frameless space. The shutter device closes the wall opening by using the "deflection" of the belt to insert the conveyor belt and the return belt into the upper and lower shutters while they are stacked.

[0006] As such, according to the shutter devices of Patent Documents 1 to 3, a wall opening through which a conveyor passes can be closed when the conveyor is not in use. The applicant has subsequently continued to investigate other means for opening and closing a wall opening through which a conveyor passes. In particular, although the shutter devices in the aforementioned prior art were exclusively for specific types of conveyors, such as bar conveyors or belt conveyors, it is desirable that the wall opening can be opened and closed regardless of the type of conveyor. Prior art literature

[0007] Patent Document 1: Japanese Patent No. 6472542 Publication Patent Document 2: International Publication No. WO2023 / 079624 Pamphlet Patent Document 3: International Publication No. WO2022 / 234653 Pamphlet The problem to be solved

[0008] Therefore, taking into account the above-mentioned circumstances, the present invention aims to provide an installation structure for a shutter device, in which a shutter device capable of opening and closing a wall opening through which a conveyor passes is installed near a wall opening regardless of the type of conveyor, and to provide a shutter device that is a component of said installation structure. means of solving the problem

[0009] In order to solve the above-mentioned problem, the installation structure of a shutter device according to the present invention is an installation structure of a shutter device in which, in order to transfer a conveyed object from a first conveyor to a second conveyor, the upstream end of the second conveyor is located below the downstream end of the first conveyor, and a shutter device for opening and closing a wall opening is installed in close proximity to a wall opening through which the first conveyor passes.

[0010] The above shutter device is,

[0011] A box body in the shape of a rectangular hexahedron consisting of a ceiling section, a floor section, and four side sections, and

[0012] A support member that supports the box body by being installed upright from the installation surface so that the bottom surface portion is located above the upstream end of the second conveyor.

[0013] Equipped,

[0014] The above box body has a side opening formed in one of the four side parts and a shutter plate for opening and closing the bottom surface,

[0015] The ceiling surface portion and the other three of the four side portions are each closed by a closure body, and,

[0016] The entire perimeter edge of the above-mentioned side opening and the entire perimeter edge of the above-mentioned wall opening are connected by a covering, and

[0017] The shutter plate, the closure, and the covering are each a mesh, a plate, or a sheet, and

[0018] The downstream end of the first conveyor penetrating the wall opening is inserted into the interior of the box body from the side opening, and,

[0019] When the first conveyor and the second conveyor are in operation, the shutter plate keeps the bottom surface open, while,

[0020] When the first conveyor and the second conveyor are stopped, the shutter plate keeps the bottom surface closed.

[0021] There are many cases where a conveyor is passed through a wall opening and then the conveyed object is transferred from that conveyor to another conveyor. This is because if a single conveyor is very long, manufacturing, transportation, and installation become difficult. Additionally, there are many cases where the conveying direction is to be changed after the conveyor is passed through a wall opening. The present invention opens and closes a wall opening through which one conveyor passes by utilizing the transfer of a conveyed object between two conveyors.

[0022] The shutter device comprises a box body consisting of a ceiling portion, a floor portion, and four side portions. The downstream end of a first conveyor penetrating a wall opening is inserted into the interior of the box body through a side opening of the box body. In the box body, three side portions and the ceiling portion, excluding the side portion where the side opening is formed, are closed. Additionally, the entire perimeter edge of the side opening and the entire perimeter edge of the wall opening are connected by a covering. Accordingly, the wall opening communicates with the interior space of the box body.

[0023] Therefore, by closing the bottom surface of the box body with a shutter plate (closed state), the internal space of the box body is made into a closed space, thereby allowing the wall opening to be closed. On the other hand, by opening the bottom surface of the box body with a shutter plate, the wall opening can be opened through the internal space of the box body. In other words, the wall opening can be opened and closed by opening and closing the bottom surface of the box body with a shutter plate.

[0024] In addition, according to the present configuration, unlike the shutter devices of Patent Documents 1 to 3, the wall opening is not closed by utilizing the configuration of the conveyor itself that penetrates the wall opening, so the wall opening that the conveyor penetrates can be opened and closed regardless of the type of conveyor.

[0025] Here, the "rectangular hexahedron" shape of the box body includes a cube.

[0026] Among the mesh, panel, and sheet bodies constituting the "shutter plate," "closure body," and "covering body," metal mesh or resin mesh may be used as the "mesh." Metal panel, resin panel, or wooden panel may be used as the "panel." Among these, as the resin panel, a laminated panel structure may be used in which a core layer made of foamed resin is sandwiched between high-rigidity surface layers, exemplified by polypropylene. Furthermore, as the wooden panel, in addition to wood veneer, plywood formed by laminating multiple thin wood sheets or particle board formed by compressing small pieces of wood may be used. Additionally, as the sheet body, resin sheets, fabrics, or non-woven fabrics may be used.

[0027] In addition, since the shutter plate, the closure body, and the covering body each include cases where they are meshes, the "closed state" includes cases where air flows through these members.

[0028] Next, the shutter device according to the present invention is,

[0029] A box body in the shape of a rectangular hexahedron consisting of a ceiling surface, a floor surface, and four side surfaces, and

[0030] A support body that supports the box body by being installed upright from the installation surface

[0031] Equipped,

[0032] The above box body has a side opening formed in one of the four side parts and a shutter plate for opening and closing the bottom surface,

[0033] The ceiling surface portion and the other three of the four side portions are each closed by a closure body, and

[0034] The above shutter plate and the above closure are each composed of a mesh, a plate, or a sheet.

[0035] This is the configuration of the shutter device in the installation structure of the aforementioned shutter device.

[0036] The shutter device according to the present invention, in addition to the above configuration,

[0037] The above box body has a rectangular frame formed by a plurality of bar members, and

[0038] The above shutter plate opens and closes the bottom surface by sliding along the above frame, and

[0039] Among the plurality of the above bar members, the bar member extending in a direction orthogonal to the slide direction of the shutter plate may be made to contact the inner surface of the shutter plate according to the slide of the shutter plate.

[0040] Examples of "bar members" include L-shaped cross-section angles or square pipes. Additionally, the material of the bar member is not particularly limited and can be made of metal, resin, or wood; however, if made of metal, using stainless steel is preferable because it can increase corrosion resistance.

[0041] Depending on the object being transported by the conveyor, the first conveyor may stop and the bottom surface of the box body may be closed by the shutter plate, causing the object to be transported to fall from the downstream end of the first conveyor and adhere to the shutter plate. According to the present configuration, since a bar member extending in a direction perpendicular to the sliding direction of the shutter plate comes into contact with the inner surface of the shutter plate as the shutter plate slides, the bar member acts as a scraper. Therefore, the attached material on the inner surface of the shutter plate can be easily scraped off simply by operating the shutter plate to slide.

[0042] The shutter device according to the present invention, in addition to the above configuration,

[0043] "In at least one of the ceiling surface portion and the three side portions, the closure is a movable plate that slides along the frame, and

[0044] Among the plurality of the above bar members, the bar member extending in a direction orthogonal to the sliding direction of the movable plate may be made to contact the inner surface of the movable plate according to the sliding of the movable plate.

[0045] According to the present configuration, at least one of the three side sections where the ceiling surface and side openings of the box body of the shutter device are not formed is a movable plate that slides along the frame. Therefore, the box body can be opened simply by sliding the movable plate. As a result, access to the internal space from the outside of the box body can be made through the area where the movable plate is slid, so that, for example, cleaning the inside of the box body can be easily performed.

[0046] In addition, depending on the object being transported by the conveyor, when it falls from the first conveyor and is transferred to the second conveyor, it may scatter around and adhere to the inner surface of the closed body that covers the ceiling or side parts. According to the present configuration, a bar member extending in a direction perpendicular to the sliding direction of a movable plate constituting at least a part of the closed body comes into contact with the inner surface of the movable plate as the movable plate slides. Therefore, the bar member acts as a scraper, and the object attached to the inner surface of the movable plate can be easily scraped off simply by operating the movable plate to slide. Effects of the invention

[0047] As described above, according to the present invention, regardless of the type of conveyor, a shutter device capable of opening and closing a wall opening through which a conveyor passes can be provided, an installation structure of the shutter device installed near the wall opening, and a shutter device that is a component of the installation structure can be provided. Brief explanation of the drawing

[0048] [Fig. 1] This is a perspective view showing the closed state of the installation structure of a shutter device, which is a first embodiment of the present invention. [Fig. 2] A drawing from the perspective view of Fig. 1 with the ceiling plate, side plate, and covering omitted. [Fig. 3] This is a perspective view illustrating the open state of the installation structure of the shutter device of Fig. 1. [Fig. 4] This is a perspective view illustrating the installation structure of the shutter device of Fig. 1, showing the slides of the shutter plate, side plate, and ceiling plate. [Fig. 5] This is a side view showing the installation structure of a shutter device, which is a second embodiment of the present invention, with a part of the side plate omitted. Specific details for implementing the invention

[0049] Hereinafter, the installation structure of a shutter device (1, 1b) and the shutter device (1, 1b), which are specific embodiments of the present invention, will be explained using drawings. First, the shutter device (1) of the first embodiment and its installation structure will be explained using FIGS. 1 to 4. The installation structure of the shutter device (1) is equipped with a first conveyor (C1), a second conveyor (C2), and a shutter device (1). Hereinafter, the conveying direction in the first conveyor (C1) is referred to as the "front-back direction," and the direction that is orthogonal to the front-back direction and parallel to the conveying surface of the first conveyor (C1) is referred to as the "left-right direction."

[0050] Here, an example is provided in which the first conveyor (C1) and the second conveyor (C2) are belt conveyors that transport chicken manure, which is the material to be transported in a chicken coop. As shown in FIG. 2, the first conveyor (C1) penetrates a wall opening (A1) formed in a wall (W), and the downstream end of the first conveyor (C1) is located near the wall opening (A1).

[0051] The second conveyor (C2) is a belt conveyor that receives the material to be conveyed by the first conveyor (C1) from the first conveyor and conveys it further. As shown in FIG. 2, the upstream end of the second conveyor (C2) is located below the downstream end of the first conveyor (C1). Here, the second conveyor (C2) is exemplified as a conveyor inclined to rise toward the downstream direction, but it is not limited thereto, and the second conveyor may be a conveyor that conveys the material to be conveyed in a horizontal direction. In addition, although the case where the conveying direction by the second conveyor (C2) is orthogonal to the conveying direction by the first conveyor (C1) is exemplified here, it is not limited thereto, and the conveying direction by the second conveyor (C2) may be the same as the conveying direction by the first conveyor (C1).

[0052] The shutter device (1) comprises a box body (10) and a support body (20). The box body (10) comprises a rectangular frame and has six surfaces enclosed by the frame, namely a top surface, a bottom surface, and four side surfaces.

[0053] This frame is composed of four longitudinal members (11), four transverse members (12), and four transverse members (13), as shown in FIG. 2. Each longitudinal member (11) is extended in the vertical direction, and two pairs of longitudinal members (11) that are spaced apart in the left-right direction are spaced apart in the front-back direction. The transverse members (12) consist of two members connecting the upper ends of each of the four longitudinal members (11) in the front-back direction, and two members connecting the four longitudinal members (11) in the front-back direction from below. The transverse members (13) consist of two members connecting the upper ends of each of the four longitudinal members (11) in the left-right direction, and two members connecting the four longitudinal members (11) in the left-right direction from below. Here, the longitudinal member (11), the transverse member (12), and the transverse member (13) correspond to the "bar member" of the present invention. In addition, in this embodiment, an angular member with an L-shaped cross section is used as the longitudinal member (11), the transverse member (12), and the transverse member (13), but is not limited thereto and, for example, a square pipe can be used.

[0054] The box body (10) has a side opening (A2) formed in one of the four side parts. The other three side parts, where the side opening (A2) is not formed, are closed by a side plate (32). Additionally, the box body (10) has a top plate (31) that closes the top part. The side plate (32) and the top plate (31) are each composed of a mesh, a plate, or a sheet. Furthermore, the side plate (32) and the top plate (31) correspond to the "closing body" of the present invention.

[0055] Additionally, the box body (10) is equipped with a shutter plate (30) that opens and closes the bottom surface. As shown in FIG. 3, among the four horizontal members (12, 13) constituting the bottom surface, a flat guide bar (15) is installed along the lower surface of each of a pair of opposing horizontal members (13), and a gap slightly larger than the thickness of the shutter plate (30) is formed between the horizontal members (13) and the guide bar (15). By holding the shutter plate (30) in this gap, the bottom surface is closed (closed state) as shown in FIG. 2. Also, by sliding the shutter plate (30) within this gap, the bottom surface is opened (open state) as shown in FIG. 3. In addition, in FIG. 3, the ceiling plate (31), the side plate (32), and the covering body (J) are omitted, but in the actual open state, at least the covering body (J) connects the entire peripheral edge of each of the wall opening (A1) and the side opening (A2).

[0056] And when the shutter plate (30) slides along the horizontal member (13), the inner surface of the shutter plate (30) comes into contact with the horizontal member (12) perpendicular to the sliding direction. Accordingly, even if something is attached to the inner surface of the shutter plate (30), the horizontal member (12) acts as a scraper and scrapes off the attachment. Also, although the case where a guide bar (15) is installed along the horizontal member (13) is illustrated here, the guide bar (15) may be installed along a pair of horizontal members (12). In this case, the shutter plate (30) slides along the horizontal member (12), and the horizontal member (13) acts as a scraper.

[0057] The shutter plate (30) may be slid manually. Alternatively, a driving mechanism for sliding the shutter plate (30) may be installed in the shutter device (1). This driving mechanism may be a mechanism that moves a feed screw forward and backward by the forward and reverse rotation of a motor and transmits the movement to the shutter plate (30). Alternatively, a cylinder device that moves a piston rod forward and backward by air or oil may be used to transmit the movement of the piston rod to the shutter plate (30).

[0058] In this embodiment, in addition to the shutter plate (30), the ceiling plate (31) and three side plates (32) also slide along the frame. That is, the ceiling plate (31) and the side plates (32) correspond to the "movable plate" of the present invention. The configuration for sliding the ceiling plate (31) is the same as the configuration for sliding the shutter plate (30). Specifically, as shown in FIG. 4, among the four horizontal members (12, 13) constituting the ceiling portion, a flat guide bar (15) is installed along the upper surface of each of a pair of opposing horizontal members (13), and a gap slightly larger than the thickness of the ceiling plate (31) is formed between the horizontal members (13) and the guide bar (15). By holding the ceiling plate (31) in this gap, the ceiling portion is closed, and the ceiling plate (31) can be slid within this gap. In addition, by installing the guide bar (15) along a pair of horizontal members (12), the ceiling plate (31) may be slid along the horizontal members (12).

[0059] In addition, in each of the three side sections where the side plate (32) is installed, a flat guide bar (16) is installed along the outer surface of an upper and lower pair of transverse members (transverse member (12) or transverse member (13)). The side section is closed by holding the side plate (32) in the gap between the transverse member and the guide bar (16), and the side plate (32) can be slid within this gap. Also, although the case is illustrated here where the guide bar (16) is shorter than the transverse member and multiple guide bars (16) are installed along one transverse member, the length of the guide bar (16) may be approximately the same as the length of the transverse member.

[0060] In addition, regarding the slide of the side plate (32), the slide direction may be set to the up-and-down direction by installing a guide bar (16) along the outer surface of the member (11).

[0061] In addition, when the shutter plate (30), the movable side plate (32), and the ceiling plate (31) are configured as sheet bodies, that is, when the sliding plate is configured as a sheet body, it is preferable to apply tension to the sheet body by holding the sheet body in the frame body.

[0062] In the same way as when sliding the shutter plate (30), when sliding the ceiling plate (31) and the side plate (32), a horizontal or vertical member extending in a direction perpendicular to the sliding direction acts as a scraper.

[0063] In addition, the shutter plate (30), the ceiling plate (31), and the three side plates (32) can be easily detached from the box body (10) simply by sliding each one. Therefore, for example, the inside of the box body (10) can be easily cleaned.

[0064] The support body (20) supports the box body (10) on the installation surface so as to form a space for positioning the upstream end of the second conveyor (C2) below the bottom surface of the box body (10). In this embodiment, the support body (20) is a support column located on the extension of each of the four longitudinal members (11), and a male thread is formed on the outer surface. The longitudinal members (11) extend downward from the bottom surface, and a horizontal surface (14) is installed at the lower end thereof. A hole is formed in the horizontal surface portion (14), and the horizontal surface portion (14) is inserted between the horizontal surface portion (14) and the support member (20) by fastening a nut to the support member (20) that passes through the hole portion, thereby connecting the vertical material (11) and the support member (20). By adjusting the fastening position of the horizontal surface portion (14) relative to the support member (20), the height from the installation surface of the box body (10) can be adjusted. Additionally, if there is no need to adjust the height of the box body (10), the support member may be configured by extending the vertical material (11) itself downward from the bottom surface portion.

[0065] In addition, although the support body (20) is exemplified here as a support column, it is preferable to have a structure that forms a space for positioning the upstream end of the second conveyor (C2) below the bottom surface of the box body (10). For example, the support body may be constructed with two plates installed vertically from the installation surface, spaced apart from each other, and the upstream end of the second conveyor (C2) may be positioned between the two plates. Alternatively, the support body may be a structure in which the ends of the same side of the two plates mentioned above are connected by a third plate installed vertically from the installation surface, and the upstream end of the second conveyor (C2) may be positioned in the space enclosed by the three plates.

[0066] Next, the method of using the shutter device (1) will be explained. As shown in FIG. 2, the shutter device (1) is installed so that the bottom surface of the box body (10) is positioned above the upstream end of the second conveyor (C2). The downstream end of the first conveyor (C1), which passes through the wall opening (A1), is inserted through the side opening (A2) and positioned inside the box body (10).

[0067] In this installation structure, the side opening (A2) and the wall opening (A1) of the box body (10) face each other. As shown in FIG. 1, the entire perimeter edge of the side opening (A2) and the entire perimeter edge of the wall opening (A1) are connected by a covering body (J). Here, the case where the covering body (J) is a mesh body is illustrated, but it may also be a sheet body or a plate body.

[0068] In addition, although belt conveyors are illustrated here as the first conveyor (C1) and the second conveyor (C2), various conveyors such as bar conveyors and plate conveyors can be used regardless of the type of conveyor.

[0069] When the first conveyor (C1) and the second conveyor (C2) are stopped (not in use), the bottom surface, ceiling surface, and three side parts of the box body (10) where the side opening (A2) is not formed are closed by the shutter plate (30), ceiling plate (31), and side plate (32), respectively, as shown in FIG. 1. In this state, the internal space of the box body (10) communicating with the wall opening (A1) is closed. Therefore, the wall opening (A1) can be closed through the box body (10).

[0070] When operating the first conveyor (C1) and the second conveyor (C2) to transfer the object to be transported from the first conveyor (C1) to the second conveyor (C2), as shown in FIG. 3, the shutter plate (30) is slid to detach it from the box body (10), and the bottom surface is left open. The object to be transported, which has been conveyed by the first conveyor (C1), falls from the downstream end of the first conveyor (C1) and is placed at the upstream end of the second conveyor (C2), and is further transported by the second conveyor (C2).

[0071] Next, the installation structure of the shutter device (1b) and the shutter device (1b) of the second embodiment of the present invention will be explained using FIG. 5. In addition, components identical to those of the first embodiment are given the same reference numerals and detailed descriptions are omitted.

[0072] The difference between the second embodiment and the first embodiment is that the driving mechanism (40) for sliding the shutter plate (30b) is held in the second conveyor, and the second conveyor (C2) is inclined so that the shutter plate (30b) is inclined parallel to the conveying surface of the second conveyor (C2).

[0073] The driving mechanism (40) rotates the feed screw (43) in the forward and reverse directions by the forward and reverse rotation of the motor (41). The motor (41) is attached to the second conveyor (C2) by a motor support (42) such that the output shaft extends parallel to the inclination direction of the second conveyor (C2) and also extends toward the box body (10b).

[0074] A nut (44) is screw-coupled to the feed screw (43). A stopper (45) that limits rotation is fixed to the nut (44). Accordingly, when the feed screw (43) is rotated forward and in reverse by the motor (41), the nut (44) does not rotate and moves forward and backward along the feed screw (43). Therefore, when the nut (44) with the stopper (45) attached is fixed to the end of the shutter plate (30b), the shutter plate (30b) slides along the feed screw (43).

[0075] Since the driving mechanism (40) is configured in this way, the box body (10b) needs to be configured to slide the shutter plate (30b) parallel to the inclined direction of the second conveyor (C2). Therefore, in the box body (10b), among the horizontal members (12, 13) constituting the bottom surface, the horizontal member (here, horizontal member (12)) extending in the sliding direction of the shutter plate (30b) is fixed to the vertical member (11) so as to be parallel to the inclined direction of the second conveyor (C2).

[0076] With this configuration, when the motor (41) rotates the feed screw (43) in one direction, the non-rotatable nut (44) moves along the feed screw (43) to the downstream side of the second conveyor (C2), causing the shutter plate (30b) to slide and open the bottom surface of the box body (10b). Then, when the motor (41) rotates the feed screw (43) in the opposite direction, the nut (44) moves along the feed screw (43) to the upstream side of the second conveyor (C2), causing the shutter plate (30b) to slide and close the bottom surface of the box body (10b).

[0077] For example, if the second conveyor (C2) is inclined and the shutter plate is horizontal, the direction in which the shutter plate is slid must be such that it does not interfere with the second conveyor (C2). For instance, the shutter plate is slid outward toward the box body in a direction perpendicular to the direction in which the second conveyor (C2) extends. In this case, in addition to the space for installing the second conveyor (C2) and the space for installing the box body, a space for sliding the shutter plate is required around the box body. Furthermore, if the shutter plate sliding in this direction is driven by a driving mechanism, an additional space for installing the driving mechanism is required outside the box body.

[0078] In this regard, in the second embodiment, since the shutter plate (30b) is slid along the conveying direction of the second conveyor (C2), space is not required solely for sliding the shutter plate (30b), thus enabling space saving. Therefore, the second embodiment is suitable for cases where the space around the box body (10b) is narrow.

[0079] In addition, sliding the shutter plate (30b) in the conveying direction of the second conveyor (C2) is difficult to do manually, but in the second embodiment, the sliding in that direction is realized by the driving mechanism (40) held on the second conveyor (C2). Also, instead of the driving mechanism (40) that rotates the feed screw (43) by the motor (41), even if a cylinder device that moves the piston rod forward and backward is used as the driving mechanism, the shutter plate (30b) can be moved forward and backward in the conveying direction of the second conveyor (C2).

[0080] In addition, although the conveying direction by the second conveyor (C2) is exemplified here as being the same as the conveying direction by the first conveyor (C1), it is not limited thereto, and the conveying direction by the second conveyor may be a direction perpendicular to the conveying direction by the first conveyor.

[0081] Although the present invention has been described above with reference to suitable embodiments, the present invention is not limited to the above-described embodiments, and as shown below, various improvements and design changes are possible within the scope of not departing from the essence of the present invention.

[0082] For example, although the above example illustrates the case where the first conveyor (C1) and the second conveyor (C2) are used in a chicken coop, the present invention can, of course, be applied to facilities other than chicken coops. Furthermore, although the example illustrates the case where the object to be conveyed is chicken manure, any object that does not have a problem falling from a certain height when transferred from the first conveyor (C1) to the second conveyor (C2) can be used as the object to be conveyed.

[0083] Additionally, the above examples illustrate cases where the conveying direction by the second conveyor (C2) is orthogonal to the conveying direction by the first conveyor (C1) and cases where it is the same direction. However, this is not limited thereto; if interference between the support and the second conveyor (C2) can be avoided, such as by increasing the spacing of the support, the conveying direction by the second conveyor (C2) can be set to a direction that intersects the conveying direction by the first conveyor (C1) at an angle other than a right angle.

[0084] Additionally, the above example illustrates a case where the slide of the shutter plate is driven by a motor, and the feed screw (43) is directly rotated by the output shaft of the motor (41). This is not limited to this, and the direction of the output shaft and the feed screw (43) may be parallel, and the rotation of the output shaft may be transmitted to the feed screw through a pulley and a belt, or a sprocket and a chain.
