Description

  The present invention relates to a defecation system, and more particularly, to a defecation system that is attached to a poultry cage in a poultry house that raises a large number of chickens and collects the feces excreted by the chicken using a defecation scraper. .

  Conventionally, a large number of chickens are placed in a poultry house in multi-tiered poultry cages (or multi-stage poultry cages for poultry farming), and raising chickens for chicken or producing eggs. Yes. Here, the poultry cage is generally constructed by combining metal frame members vertically and horizontally, and has a substantially rectangular parallelepiped frame shape as a whole. The chickens in the poultry cage are restricted to a certain range of movement in the front-rear direction, left-right direction, and up-down direction. A feeding / water supply system that automatically supplies food, water, nutrients, etc. to the housed chicken at predetermined time intervals, an egg collection system that automatically collects eggs laid by the chicken, and a chicken Various systems such as a defecation system that collects excreted chicken manure are attached to the poultry cage, and these systems are centrally managed throughout the poultry house, so that the number of workers required for poultry house operations can be kept to a minimum. The inside is always kept clean and chicken breeding and egg production can be stabilized. This makes it possible to stably supply fresh and safe chicken and eggs to the market.

  The defecation system will be described in detail. The defecation system has a defecation belt installed along the longitudinal direction of the poultry cage below the chicken housed in the poultry cage. The excreted chicken dung is dropped and received by the belt outer surface of the defecation belt located below. The defecation belt is supported by a plurality of rotating rollers rotatably supported by the poultry cage. By operating a belt rotating unit such as a motor connected to the rotating roller, the defecation belt is moved in a predetermined direction. Can be rotated. The defecation belt is composed of a flexible material in an annular shape. When the belt rotation part reaches one belt end by the operation of the belt rotation part described above, the rotation direction of the belt outer surface (chicken dung conveyance direction) It is turned 180 ° and switched in the opposite direction. Further, when the other belt end is reached, the rotation direction is similarly changed by 180 °. Thereby, the rotation reciprocating orbit of the defecation belt is continued. By such movement, the chicken manure received on the outer surface of the belt is conveyed toward one belt end. Then, the poultry manure that has reached the belt end falls from the defecation belt due to its own weight and is collected by a collection container or a belt conveyor provided below the belt end. The collected chicken manure is reused as fertilizer and various fuels.

  The above-described defecation system does not always rotate the defecation belt, but is controlled so as to repeat the rotation and stop of the defecation belt at predetermined intervals. Therefore, it may take a certain amount of time from when the feces fall from the poultry cage and are received on the outer surface of the belt until the fecal dropping starts to rotate. Here, chicken droppings contain a lot of moisture, and dropped chicken droppings may be dried over the above time and may adhere to the outer surface of the belt. For this reason, even if the defecation belt is rotated in such a state, chicken feces that have arrived at the end of the belt may not be smoothly dropped due to their own weight due to the sticking. The chicken manure that remains stuck to the outer surface of the belt moves along the reverse direction of the defecation belt, falls in a place where no collection container is installed, or remains stuck to the outer surface of the belt. Rotation may continue. As a result, it was a factor that deteriorated the overall hygiene of the house.

  Therefore, a defecation scraper is provided in which a thin scraper piece contacts the belt outer surface along the belt width direction. As a result, the scraper piece is in contact with the belt outer surface of the defecation belt without any gap by a constant pressing force, so that the chicken manure adhered to the belt outer surface is scraped off (scraped) by the scraper piece. And can be reliably removed from the defecation belt. Thereby, the sanitary state in the above-described poultry house is not deteriorated.

  However, the above-described defecation system sometimes has the following problems. That is, it is difficult to properly adjust the contact state of the scraper piece of the defecation scraper that is contacted along the belt width direction of the defecation belt, in other words, the pressing amount of the scraper piece against the defecation belt. there were. Here, when the defecation system is stopped (when the rotation of the defecation belt is stopped), the defecation scraper is set at a position (separated position) away from the belt outer surface of the defecation belt, When the defecation belt was rotated, it was set at a position (removal position) to be brought into contact with the outer surface of the belt so as to be pressed with a constant pressing force. That is, the defecation scraper is formed so that it can be set at two positions, a separation position and a removal position.

  However, when the contact state between the outer surface of the belt and the scraper piece of the defecation scraper is strong, that is, when the scraper piece of the defecation scraper is pressed against the outer surface of the belt more than necessary, the defecation belt and the scraper The frictional force between the pieces became large, and the smooth rotation of the defecation belt could be hindered. Further, there is a strong possibility that a part of the defecation belt is scraped by the scraper piece, and that both the scraper piece and the defecation belt are worn out violently. Therefore, it is necessary to replace each of them, and the frequency of replacement work or maintenance work for confirmation may increase.

  On the other hand, when the contact state between the belt outer surface and the scraper piece of the defecation scraper is weak, that is, the pressing of the scraper piece of the defecation scraper against the belt outer surface is weak, or there is a gap between the belt outer surface and the scraper piece. However, although the frictional force between the defecation belt and the scraper piece is small, the scraping operation of the chicken dung with the scraper piece is not sufficiently performed, and it may not be completely removed. As a result, chicken droppings adhered to the defecation belt remained, and the sanitary condition in the chicken house sometimes deteriorated.

  Here, the removal position where the defecation scraper comes into contact with the defecation belt, and the scraper displacement mechanism that displaces the defecation scraper to the separation position separated from the defecation belt, includes a link portion having a plurality of link arms, an operation lever, and the like. For example, the defecation scraper can be displaced to the removal position and the separation position by operating the lever in the vertical direction of the operation lever. However, in the conventional defecation system, the displacement of the defecation scraper can only be set at two positions, a removal position and a separation position. The contact of the defecation scraper with the defecation belt is not constant depending on the surrounding environment or various conditions, and may be slightly different for each rotation of the defecation belt. Therefore, it may be difficult to make the pressing condition of the defecation scraper constant. In particular, in the case of a feces removal scraper that can be set only at the two positions described above (removal position and separation position), such adjustment work may be difficult.

  Generally, adjust the distance between the belt outer surface in the belt width direction of the defecation belt and the scraper piece to be constant for the defecation scraper retracted to the separation position, and then rotate the operation lever to the treatment position. Thus, the scraper piece was pressed. That is, it is necessary to empirically predict the pressing state of the defecation scraper at the removal position in advance at the separation position and adjust the interval between the defecation scraper and the defecation belt. Such adjustment work is cumbersome and may require a lot of adjustment time. In addition, problems such as breakage of the defecation scraper and defecation belt due to improper adjustment, and deterioration of hygiene due to insufficient removal have occurred.

  Therefore, in view of the above circumstances, the present invention maintains the relative positional relationship of the defecation scraper disposed at the belt end portion of the defecation belt with the defecation belt in multiple stages, and the defecation scraper with respect to the defecation belt. An object of the present invention is to provide a fecal removal system that can adjust the pressing amount of the stool in advance.

  In order to solve the above-described problems, the defecation system of the present invention has the following: “A belt-shaped defecation belt and a poultry cage that is rotatably supported by the poultry cage. A belt support unit having a plurality of rotating rollers supported in an oval shape; a belt rotating unit connected to the belt support unit and configured to rotate the defecation belt supported by the rotating roller in a predetermined direction; and the defecation A thin scraper piece disposed along the belt width direction of the defecation belt, a scraper base for supporting the scraper piece, and the scraper base around the poultry cage in a predetermined range. A defecation scraper having a scraper shaft that is pivotally supported, a link portion connected to the defecation scraper, and a lever connected to the link portion and pivotally supported by the poultry cage A removal position at which the scraper piece abuts against the belt outer surface of the defecation belt according to the lever position, a separation position at which the scraper piece is separated from the belt outer surface, and the removal position and the separation. An operation lever for displacing the defecation belt to an adjustment position between the positions, and a lever position for holding the operation lever at a position for displacing the defecation scraper to the removal position, the separation position, and the adjustment position, respectively. And a scraper displacement mechanism having a holding portion.

  Here, the defecation belt is composed of, for example, a sheet member formed of a polypropylene resin or the like in a wide sheet shape, and connects the sheet end portions of the belt-shaped sheet member cut to a predetermined belt width. Therefore, it is configured so as to exhibit an annular shape. In addition, the sheet | seat member which comprises a defecation belt is a raw material which has flexibility and can deform | transform by stress. Therefore, by being supported by the plurality of rotating rollers of the belt support part, more specifically, by supporting the roller surface of the rotating roller and the belt inner surface of the belt-shaped feces belt, The feces belt can be supported with an oval cross section. At this time, the longitudinal direction of the defecation belt coincides with the longitudinal direction of the poultry cage. As a result, the rotation roller is driven to rotate by a belt rotation unit connected to a part of the rotation roller of the belt support unit via a drive transmission mechanism, so that the defecation belt is in a certain direction like a belt member of a belt conveyor. Can be rotated. At this time, the chicken manure received on the outer surface of the belt is conveyed toward one belt end in accordance with the rotation. Here, since the configuration of the belt support portion and the belt rotation portion uses a known technique, the description thereof is omitted here.

  On the other hand, the defecation scraper contacts the outer surface of the defecation belt with the scraper piece, and scrapes and removes the chicken feces adhering to the outer surface of the belt. A thin scraper piece along the belt width is provided so as to be able to come into contact with one belt end of the defecation belt. Further, the scraper displacement mechanism unit is connected to the defecation scraper and the link mechanism unit, and according to the lever position of the operating lever, the adjustment position between the removal position and the separation position, the separation position, And holding at each position is regulated by a lever position holding portion.

  Therefore, according to the defecation system of the present invention, the movable range of the operation lever is regulated in three stages by the lever position holding unit, and based on this, the defecation scraper is installed between the removal position and the separation position. And the belt outer surface can be set at an adjustment position, an adjustment position, and a separation position, respectively. Here, the adjustment position is a position where a slight gap is formed between the scraper piece of the defecation scraper and the belt outer surface, and the deviation of the gap in the belt width direction can be adjusted at this position. After adjusting at such an adjustment position, the pressing state of the defecation scraper at the removal position is stabilized by operating the operation lever to displace the defecation scraper so as to be at the removal position. Thereby, the pressing of the defecation scraper against the defecation belt is in an appropriate state, the chicken excrement on the outer surface of the belt is surely removed, and unnecessary friction does not occur.

  Further, the fecal removal system according to the present invention has the above-described configuration. “The operation lever is provided along a cage side surface of the poultry cage, and the lever position holding portion has a flat plate shape and penetrates the operation lever. A punching hole having a possible punching hole, which is installed at the cage end of the poultry cage, the punching hole being a removing part for displacing the defecation scraper to the removal position, an adjusting part for displacing to the adjustment position, and A separation portion that is displaced to the separation position is arranged in parallel in the vertical direction, and further includes a connection portion that connects the removal portion, the adjustment portion, and the adjustment portion, and rotates the operation lever in the vertical direction. "It may be".

  Therefore, according to the defecation system of the present invention, the lever position holding portion has a flat plate shape, has a punching hole portion that can penetrate the operation lever, and holds the operation lever in a predetermined position by the shape of the punching hole portion. Is possible. That is, the operation lever set in each hole can hold the position when a part of the lever bottom surface of the long-shaped operation lever contacts the hole wall of each hole. Thereby, the lever position of the operating lever can be maintained, and the position of the defecation scraper can be determined via the lever shaft and the link mechanism connected to the operating lever.

  As an effect of the present invention, the defecation scraper can be displaced and held at the removal position, the separation position, and the adjustment position, and in particular, the clearance between the defecation belt and the defecation belt can be confirmed in advance with the adjustment device, By displacing to the removal position, the pressing force (contact state) of the defecation scraper can be made constant.

  Hereinafter, a defecation system 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 5. Here, FIG. 1 is a schematic cross-sectional view seen from the side showing a schematic configuration of the defecation scraper 2 of the defecation system 1 of the present embodiment held in the separation position DP, and FIG. 2 is a lever position holding portion. 3 is a schematic cross-sectional view seen from the side showing a schematic configuration in a state where the defecation scraper 2 is held at the adjustment position CP, and FIG. 4 is a diagram illustrating the removal of the defecation scraper 2. FIG. 5 is a schematic cross-sectional view seen from the side showing a schematic configuration in a state of being held at the position SP, and FIG. 5 is a perspective view showing configurations of the operation lever 4 and the lever position holding unit 3. Here, the defecation system 1 of the present embodiment is attached to a poultry cage 5 in which chickens (not shown) are housed, and the chicken feces 6 are received below the poultry cage 5 and are arranged along the longitudinal direction. An example is shown in which the chicken manure 6 is collected so that it can be reused as a fertilizer or the like.

  As shown in FIGS. 1 to 5, the defecation system 1 according to the present embodiment includes a belt-shaped defecation belt 7, a belt support portion 8 that supports the defecation belt 7 in a laid manner, and a belt support portion 8. A belt rotating part (not shown) for rotating the defecation belt 7 supported in a predetermined direction, and chicken feces 6 adhering to the belt outer surface 7a of the defecation belt 7 are scraped and removed by the belt end 7b of the defecation belt 7. And a scraper displacement mechanism 12 that displaces and sets the defecation scraper 2 to the removal position SP, the separation position DP, and the adjustment position CP, respectively.

  More specifically, the defecating belt 7 is composed of a wide resin sheet made of polypropylene resin, and is constructed as an endless belt-like member by forming it in an annular shape. Since the polypropylene resin is a flexible material, it can be freely deformed according to the stress, and can be formed into an oval cross section by being supported by the belt support portion 8 described later. On the other hand, the belt support portion 8 has a plurality of rotation rollers 13 that are rotatably supported on the side surfaces of the cage of the poultry cage 5 by matching the rotation axis direction along the direction orthogonal to the longitudinal direction of the poultry cage 5. Configured. Here, the belt inner surface 7c of the defecation belt is brought into contact with the roller surface 13a of the rotating roller 13, and a predetermined tension is applied to support the defecation belt 7. Thereby, rotation of the defecation belt 7 according to the rotation roller 13 under the poultry cage 5 is enabled.

  On the other hand, the belt rotation unit includes a rotation drive unit that generates a drive rotation force such as a motor, and a drive transmission unit (all not shown) that transmits the generated drive rotation force to the above-described rotation roller 13. It is configured. The rotating roller 13 connected to the drive transmission unit (for example, a gear chain or the like) may be a part of the plurality of rotating rollers 13. Thereby, the defecation belt 7 supported by the rotation roller 13 is interlocked with the rotation of the rotation roller 13 (see arrow A in FIG. 4), and the upper defecation belt 7 rotates toward the belt end 7b. (See arrow B in FIG. 4). Here, the belt end portion 7 b of the defecation belt 7 supported by the belt support portion 8 and the cage end 5 a of the poultry cage 5 substantially coincide with each other. Then, at the belt end 7b, the rotation direction of the defecation belt 7 is changed by 180 ° from top to bottom. As a result, the defecation belt 7 originally located on the upper side is located on the lower side and moves in the opposite direction. Thereby, the endless feces removal belt can continue reciprocating rotational motion repeatedly. In addition, a well-known structure can be utilized for the belt rotation part which rotates the defecation belt 7, and detailed description is abbreviate | omitted here.

  The defecation scraper 2 in the defecation system 1 of the present embodiment is provided along the belt width direction of the defecation belt 7 (corresponding to the depth direction from the front side of the drawing in FIG. 1 and the like), and 180 by one belt end 7b. A thin scraper piece 11 that can be brought into contact with the belt outer surface 7a of the bent defecation belt 7 obliquely below the belt end 7b, a scraper base 14 that supports the scraper piece, and the scraper base 14 in the poultry cage And a scraper shaft 15 pivotally supported with respect to 5.

  On the other hand, the scraper displacement mechanism unit 12 can displace the relative positional relationship of the defecation scraper 2 with respect to the defecation belt 7, and the first arm connected to the scraper shaft 15 of the defecation scraper 2 described above. 19, a link portion 22 having a second arm 21 having one end connected to the arm end of the first arm 19 via a link shaft 20 and the other end connected to a lever shaft 23 described later; A shaft end 23a is projected from a cage side surface 5b of the poultry cage 5 connected to the other end, and is supported by a lever shaft 23 pivotally supported in the vertical direction with respect to the poultry cage 5, and a shaft end of the lever shaft 23 23a and one end are connected, and the long lever-like operation lever 4 extended in the direction of the cage end 5a and the rotation of the operation lever 4 according to the lever shaft 23 are restricted to a predetermined range, and the operation lever 4 is predetermined. In the position It has and a lever position holding unit 3 for holding the Kaiteki. Here, one end of the operation lever 4 connected to the lever shaft 23 is formed with a pair of separation pieces 16a and 16b separated with the lever shaft 23 interposed therebetween, and an adjustment bolt 17 penetrating the separation pieces 16a and 16b is provided. It has been. Bolt grooves (not shown) that can be screwed onto the adjusting bolts 17 are formed at the opposing positions of the separation pieces 16a and 16b. Thereby, by rotating the adjusting bolt 17 in the fastening direction, a force for bringing the separating pieces 16a and 16b close to each other by the screwing propulsive force acts, and the operation lever 4 and the lever shaft 23 are firmly connected. . On the other hand, by rotating the adjustment bolt 17 in the fastening release direction, the pair of separation pieces 16a and 16b are separated from each other, and the connection between the operation lever 4 and the lever shaft 23 is released. In this state, the relative positional relationship between the defecation belt 7 and the defecation scraper 2 described later can be adjusted.

  Here, as shown mainly in FIGS. 2 and 5, etc., the lever position holding portion 3 is arranged in the direction from the cage end 5a of the poultry cage 5 to the cage side surface 5b (the front side of the page in FIG. 1 or the like, or the page in FIG. This is a flat metal member extending in the left direction, and has a through-hole portion 26 that is punched out so as to be able to penetrate the operation lever 4. Here, the shape of the through-hole portion 26 is such that a hole-shaped separation portion 29, an adjustment portion 28, and a removal for displacing the defecation scraper 2 to the separation position DP, the adjustment position CP, and the removal position SP in stages. The position determination holes made up of the portions 27 are respectively arranged in the vertical direction, and the adjustment portion 28 and the separation portion 29, and the position determination holes adjacent to each other in the vertical direction of the removal portion 27 and the adjustment portion 28 are connected to each other. The moving part 30 has a vertically long hole shape. Furthermore, the screw fixing hole 31 for screw-fixing to the cage end 5a of the poultry cage 5 is provided in two places on one side. In addition, the removal protrusion 27 at the lowermost position of the through-hole portion 26 is provided with a restriction protrusion 32 that restricts the movement of the operation lever 4 in the horizontal direction at a part above the movement portion 30 and the removal portion 27. ing.

  The horizontal width of the vertically long moving portion 30 is formed to be slightly wider than the lever width of the operation lever 4. Accordingly, the operation lever 4 that moves the moving unit 30 is restricted from moving in the horizontal direction and can move only in the vertical direction. On the other hand, the removal unit 27, the adjustment unit 28, and the separation unit 29 are formed wider than the lever width of the operation lever 4. Therefore, by slightly moving the operation lever 4 that has reached the removal unit 27 or the like in the horizontal direction, for example, the hole bottom surface 27a of the removal unit 27 and the lever bottom surface 4a of the operation lever 4 may be in contact with each other. The lever position of the operation lever 4 can be fixed. Thereby, the relative position with respect to the defecation belt 7 of the defecation scraper 2 displaced in conjunction with the lever position of the operation lever 4 can be set at an arbitrary position.

  Next, an example of the movement of the defecation scraper 2 in the defecation system 1 of the present embodiment is exhausted. In the defecation system 1 of the present embodiment, when the operation of the defecation belt 7 is stopped, that is, the rotation of the defecation belt 7 is not performed, and the relative position between the defecation belt 7 and the defecation scraper 2 When the relationship has not changed, the operation lever 4 is set in the separation portion 29 above the lever position holding portion 13 as shown in FIG. When held at the lever position of the operation lever 4, the scraper piece of the feces removal scraper 2 is obtained by the interlocking link action of the lever shaft 23 connected to the operation lever 4, the link portion 22 of the scraper displacement mechanism portion 12, and the scraper shaft 15. The defecation scraper 2 is located at a position (separation position DP) where 11 is separated from the defecation belt 7. In this state, it waits until rotation of the defecation belt 7 is started. At this time, chicken manure is excreted by a large number of chickens housed in the poultry cage 5, and a certain amount of chicken manure 6 is formed on the belt outer surface 7 a of the defecation belt 7 of the defecation system 1 installed below the poultry cage 5. Accepted.

  Then, rotation of the defecation belt 7 by the defecation system 1 of this embodiment is started at an operation timing regulated in advance (for example, once or twice a week). At this time, the defecation scraper 2 is adjusted before the defecation belt 7 starts rotating. First, the lever position of the operation lever 4 is moved from the separating portion 29 to the adjusting portion 28. Specifically, the operation lever 4 positioned at the separation portion 29 is shifted to the left (corresponding to the left direction in FIG. 5) while being slightly lifted, and is positioned at the moving unit 30. Then, the operation unit 4 is slowly moved downward in a state where horizontal movement is restricted by the moving unit 30 and is displaced to the position of the adjusting unit 28 provided at the center of the lever position holding unit 3. At this time, the movement of the adjusting unit 28 from the moving unit 30 is shifted to the right (corresponding to the right direction on the paper in FIG. 5) while lifting the operation lever 4 by a reverse operation to release the hand from the operation lever 4. Is done by. The operation lever 4 is urged to rotate downward by its own weight. Thereby, the operation lever 4 is set to the adjustment part 28 (refer FIG. 3).

  At this time, the adjustment bolt 7 provided at the tip of the operation lever 4 is rotated in the fastening release direction to slightly loosen the connection between the lever shaft 23 and the operation lever 4 by the pair of separation pieces 16a and 16b. Then, as shown in FIG. 3, the belt outer surface 7a of the defecation belt 7 and the one end 11a of the scraper piece 11 of the defecation scraper 2 are set in contact with each other, and the adjustment bolt 7 is fastened in this state. Rotate in the direction. As a result, the pair of separation pieces 16a and 16b come close to each other, and the connection between the operation lever 4 and the lever shaft 23 becomes strong again. Thus, the scraper displacement mechanism unit 12 can be moved in conjunction with the lever operation of the operation lever 4.

  After performing the adjustment at the adjustment position CP, the operation lever 4 is moved to the removal portion 27 of the lever position holding portion 3. The details of the lever operation have already been described, and are omitted here. As a result, as shown in FIG. 4, the end portion 11 a of the scraper piece 11 of the defecation scraper 2 comes into contact with the belt outer surface 7 a of the defecation belt 7 with a predetermined pressing force. At this time, since the adjustment of the distance between the defecation scraper 2 and the defecation belt 7 has been completed at the adjustment position CP, it is only necessary to set the lever position of the operation lever 4 from the adjustment unit 28 to the removal unit 27. The defecation scraper 2 can be brought into contact with the defecation belt 7 with a pressing force. That is, the defecation scraper 2 that is displaced by the scraper displacement mechanism 12 having the link mechanism is set in advance at the adjustment position CP, and after fine adjustment of the scraper piece 11 at the position, the contact is made by setting it at the removal position SP. The state can be stabilized (the pressing force is stable). In particular, the amount of displacement from the adjustment position CP to the removal position SP is small, and the amount of displacement by the operation lever 4 can be made constant, so that the adjustment work can be facilitated.

  In this state, the belt rotating unit is operated to rotate the rotating roller 13 of the belt supporting unit 8 (see arrow A in FIG. 4). As a result, in conjunction with the rotation of the rotating roller 13, the supported defecation belt 7 rotates in a predetermined direction (see arrow B in FIG. 4). Thereby, the chicken manure 6 placed on the belt outer surface 7 is conveyed toward one belt end portion 7b of the defecation belt 7, and most of the manure falls according to its own weight at the belt end portion 7b, and is installed below. It is transported outside the poultry house by a belt conveyor for recovery. At this time, a part of the chicken manure 6a fixed to the belt outer surface 7a is pressed without a gap between the scraper piece 11 of the defecation scraper 2 and the belt outer surface 7a of the defecation belt 7 set at the removal position SP. It is scraped off and removed according to the state. As a result, the chicken manure 6 does not remain on the belt outer surface 7a after passing through the defecation scraper 2.

  As described above, according to the defecation system 1 of the present embodiment, the operation lever 4 is operated, and the relative position of the defecation scraper 2 with respect to the defecation belt 7 is determined as the removal position SP, the separation position DP, and the adjustment position. The scraper piece 11 and the like can be adjusted in advance at the adjustment position CP before being set at the removal position SP. Thereby, the contact state of the defecation scraper 2 and the defecation belt 7 when set at the removal position SP can be improved, and the scraper piece 11 contacts the defecation belt 7 with an appropriate pressing force. Can be made. As a result, it is possible to eliminate the unevenness in the belt width direction, prevent the defecation scraper 2 and the like from being damaged and worn, and completely scrape and remove the chicken manure 6.

  The present invention has been described with reference to preferred embodiments. However, the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention as described below. And design changes are possible.

  That is, in the defecation system 1 of the present embodiment, the operation bolt 4 and the lever shaft 23 are loosened by the adjustment bolt 17 provided at the tip of the operation lever 4 so that the defecation scraper 2 is relative to the defecation belt 7. Although what adjusts a position was shown, it is not limited to this, What is necessary is just to have a function which can be adjusted by other composition in adjustment position CP. For example, the lever shaft 23 connected to the link portion 22 or the position of the scraper shaft 15 of the defecation scraper 2 may be variably formed so as to enable an appropriate contact state.
