Description

Foraging opening adjustment device

The present invention relates to a feeding opening adjusting device for adjusting the size of the feeding opening of a cage for raising chicks in the height direction.

In a facility where a large number of birds are raised in a cage row in which a large number of cages are juxtaposed, bird food is supplied to a long bait arranged along the outer surface of the cage in the longitudinal direction of the cage row. Birds get their necks out of the foraging opening provided at the bottom of the cage and swallow the food in the bait. Therefore, the feeding opening is set to a size that allows the bird to get out of the neck but not the body. However, as chicks grow, their bodies grow larger every day. Therefore, in the cage for raising chicks, it is necessary to widen the foraging opening in the height direction as the chick grows.

As shown in FIG. 5, the adjustment of the size of the foraging opening in the height direction can be performed by raising and lowering the shield plate 30 that partially covers the opening provided in the lower portion of the cage 60. it can. Specifically, the wire 61 is stretched on the side surface of the cage 60, but an opening is formed in the lower portion of the side surface facing the bait bowl 70 to which the food 99 is supplied without the wire 61 being stretched. Has been. The shield plate 30 is a plate material that is long in the lateral direction, and covers the opening from above. The space opened below the shield plate 30 without being covered by the shield plate 30 is a feeding opening 35 through which the chick 90 can get out of the neck. The size of the opening 35 can be changed in the height direction.

As a foraging opening adjustment device that changes the size of the foraging opening in the height direction, a device that raises and lowers the shield plate by rotating the operation arm and transmitting the rotation to the shield plate has been used. Has been.

However, in the conventional foraging opening adjusting device, the operation arm is rotated by rotating a support shaft that rotates integrally with the operation arm using a tool such as a wrench. Therefore, the rotation angle of the operation arm has to be adjusted by the movement of the arm for the operator to rotate the tool, and there is a problem that fine adjustment is difficult. The body of a chick that has just been placed in a chick-raising cage is very small and grows with each day, so the size of the feeding opening must always be suitable for the chick's body. There was a demand for fine adjustment of the size of the foraging opening.

Therefore, in view of the above circumstances, the present invention has an object to provide a foraging opening adjusting device that can finely adjust the size of the foraging opening of the cage for raising chicks in the height direction. To do.

In order to solve the above-mentioned problem, the foraging opening adjusting device according to the present invention is described as follows: “In a cage for raising chicks, a shield plate that partially covers an opening provided at a lower portion of a side facing the bait cage is moved up and down. A foraging opening adjusting device that changes the size of the foraging opening as a space opened below the shield plate in the opening in the height direction. And is rotatably supported by an operation arm that applies a lifting force to the shield plate by rotating together with the support shaft, and a support fixed to the gantry, and a male screw is provided on the outer peripheral surface. A shaft formed, a female screw portion having a hole portion penetrating the shaft, and a female screw screwed into the male screw formed on the inner peripheral surface of the hole portion; Female thread around the shaft axis The stopper prevents the rotation, and the stopper prevents the rotation and moves with the female screw portion that advances and retreats in the axial direction of the shaft as the shaft rotates. And a handle for rotating the shaft ”.

As an aspect in which the “operation arm” “applies a lifting force to the shield plate”, the operation arm is connected to the shield plate via another arm, and the operation arm is directly connected to the shield plate. The embodiment can be illustrated.

The “base” in which the operation arm is fixed by the support shaft and the “base” in which the support body supporting the shaft is fixed may be the same or different. In addition, these mounts may be a part of a frame that supports a cage for raising chicks, or may be a separate body from the frame.

As a mode in which the “stopper” “prevents the rotation of the female screw portion around the axis of the shaft”, the support body supporting the shaft has a side wall portion along the shaft, An integrated or integrated stopper protrudes toward the side wall, and the stopper collides with the side wall when rotating about the axis of the shaft. A long groove extending in the axial direction of the shaft is formed on the side wall of the support. Formed, a stopper projecting from the female screw part is inserted into the long groove, the support has an outer cylinder having a slit that penetrates the contact part, and from the female screw part to a flange shape An example in which the stopper protrudes and the inner shape of the cross section of the outer cylinder and the outer shape of the stopper are non-circular such as a polygon or an ellipse can be exemplified.

Since the “contact portion” is configured to move together with the female screw portion, it is integrated with or integrated with the female screw portion. In order for the contact portion to contact the operation arm due to the movement of the contact portion as the female thread portion advances and retracts in the axial direction of the shaft, the moving path of the contact portion rotates within a predetermined angle range. It only needs to be on the track surface of the operation arm.

In this configuration, when the shaft is rotated by turning the handle, the female screw portion screwed with the male screw of the shaft tries to rotate around the shaft axis. However, since the rotation is blocked by the stopper, the female screw portion moves in the axial direction of the shaft. When the abutting portion moves together with the female screw portion, the abutting portion abuts on the operation arm on the movement path, so that the operating arm is pushed by the abutting portion and rotates around the axis of the support shaft. That is, in this configuration, the operating arm is rotated by rotating the shaft and moving the female screw portion. Since the female screw part advances and retreats by screwing with the male screw, even if the shaft is rotated by turning the handle, the female screw part moves only little by little. Thereby, the rotation angle of the operation arm can be finely adjusted by an extremely easy operation of turning the handle, and as a result, the height at which the shield plate moves up and down can be finely adjusted.

In the cage for raising chicks, the size of the foraging opening is expanded in the height direction as the chick grows. Therefore, it is desirable that the height of the shield plate can be finely adjusted when the shield plate is raised. In other words, it is desirable that the direction in which the operation arm rotates when pushed by the contact portion is the direction in which the shield plate rises.

In addition to the above-described configuration, the foraging opening adjusting device according to the present invention includes: “The support has a side wall portion parallel to the shaft, and a member in which two flat plates form an L-shape. The contact portion and the stopper are configured, and one of the flat plates is the contact portion, and is fixed to the female screw portion with the shaft passing through the second hole portion communicating with the hole portion. And the other flat plate is the stopper and is close to the side wall portion ”.

In this configuration, the stopper portion and the contact portion are configured by an extremely simple member called an L-shaped member. Such an L-shaped member can be manufactured very easily, for example, by simply bending a metal flat plate.

As described above, as an effect of the present invention, it is possible to provide a feeding opening adjusting device that can finely adjust the size of the feeding opening of the cage for raising chicks in the height direction.

It is a principal part perspective view of the feeding opening adjustment apparatus which is one Embodiment of this invention. It is a principal part perspective view of the foraging opening adjusting device seen from the angle different from FIG. FIG. 3A and FIG. 3B are diagrams for explaining raising and lowering of the shield plate due to the rotation of the operation arm. FIG. 4A and FIG. 4B are diagrams for explaining the adjustment of the rotation angle of the operation arm by the rotation of the shaft. FIG. 5 is a diagram illustrating a foraging opening formed below the shield plate.

Hereinafter, a feeding opening adjusting device 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4.

The foraging opening adjusting device 1 of the present embodiment opens and closes the shield plate 30 that partially covers the opening provided in the lower part of the side facing the bait bowl 70 in the cage 60 for raising chicks. It is a device that changes the size of the foraging opening 35 as a space open below the shield plate 30 in the height direction, and is pivotally supported on the gantry by the support shaft 11, and is integrated with the support shaft 11. The shaft 41 is rotatably supported by the operating arm 10 that applies a lifting force to the shield plate 30 and the support 50 fixed to the gantry, and has an external thread formed on the outer peripheral surface. A female screw portion 42 having a hole portion 42h penetrating the shaft 41 and having a female screw threadedly engaged with the male screw formed on the inner peripheral surface of the hole portion 42h, and a female screw portion 42. Around the axis of shaft 41 The stopper 43 that prevents rotation and the female screw portion 42 that moves forward and backward in the axial direction of the shaft 41 along with the rotation of the shaft 41 due to the rotation of the shaft 43 being blocked by the stopper 43, are moved to the operation arm 10 on the movement path. An abutting portion 44 that abuts and a handle 45 for rotating the shaft 41 are provided.

More specifically, the feeding opening adjusting device 1 is installed at the end of a cage row in which a large number of cages 60 for raising chicks are juxtaposed in the horizontal direction. A bottom surface 83 connecting a pair of opposing support plates 82 is fixed to the frame 81 of the gantry, and an end portion of the bait bowl 70 is inserted into a gap between the pair of support plates 82. . The bait bowl 70 has a long box shape opened upward, and is arranged along the outer surface of the cage 60 in parallel with the cage row. Of the two

edges

71 and 72 of the bait bowl 70, the one closer to the cage 60, that is, the edge 71 on the side where the chick inserts the neck is set low.

The support shaft 11 is inserted through a pair of support plates 82 below the bait 70, and the lower end of the operation arm 10 is fixed to the end portion of the support shaft 11 on the cage 60 side. A polygonal head 12 that is rotated by a socket wrench, a box wrench or the like is formed at the other end of the support shaft 11. Here, a quadrangular prism-shaped head 12 is illustrated.

One end of a long connecting arm 20 is connected to the upper end of the operation arm 10 so as to be rotatable around the axis P1. The other end of the connecting arm 20 is connected to the end of the shield plate 30 so as to be rotatable around the axis P2. The shield plate 30 is an elongated flat plate extending in parallel with the side surface of the cage 60 with a length exceeding the entire length of the cage row. A wire (not shown) is stretched on the side surface of each cage 60, but an opening is formed in the lower portion of the side surface facing the bait bowl 70 without the wire being stretched. The shield plate 30 partially covers the opening from above, so that the space opened below the shield plate 30 is the foraging opening 35. By raising and lowering the shield plate 30, the foraging opening 35 The size changes in the height direction.

The shield plate 30 is provided with a plurality of inclined slits 31 at regular intervals (only one slit 31 is shown in FIG. 3), and the inclination of the slit 31 is higher on the side closer to the operation arm 10. Yes. The cage 60 is provided with vertical frame members 62 at the same intervals as the distances between the slits 31, and guide pins 63 projecting at the same height on these vertical frame members 62 are respectively slits. 31 is inserted.

The shaft 41 is supported by the support body 50 behind the operation arm 10 (on the side opposite to the bait bowl 70). The support 50 includes a base plate 51 fixed to the frame 81 of the gantry, a side wall portion 53 extending upward from the upper end side of the base plate 51, and a right angle from both sides of the side wall portion 53. And a pair of support pieces 52 extending in the direction. The shaft 41 passes through through holes 52 h provided in a pair of opposing support pieces 52, and is rotatably fastened by nuts 55 from the outside of the support pieces 52. Thereby, the shaft 41 is rotatably supported by the support body 50 and is parallel to the side wall portion 53. The shaft 41 is inclined so that the end portion close to the shield plate 30 has a lower height than the other end portion, and a handle 45 for rotating the shaft 41 is attached to the higher end portion. It has been.

The shaft 41 passes through the hole 42 h of the female screw portion 42 between the pair of support pieces 52. A contact portion 44 is fixed to the female screw portion 42, and a stopper 43 is provided integrally with the contact portion 44. Specifically, the contact portion 44 and the stopper 43 are formed of one member in which two flat plates form an L shape, and one flat plate is the contact portion 44. The contact portion 44 has a second hole (not shown) penetrating through the shaft 41 in a state where the second hole communicates with the hole 42 h of the female screw portion 42. The contact portion 44 is larger than the female screw portion 42 and protrudes outward from the female screw portion 42, particularly in a direction in which the operation arm 10 is present. On the other hand, the other of the two flat plates is a stopper 43, which is parallel to the side wall portion 53 and very close to the side wall portion 53.

With such a configuration, when the shaft 45 is rotated by turning the handle 45, the rotation of the female screw portion 42 is prevented by the stopper 43 that is parallel to and close to the side wall portion 53. Thereby, as the shaft 41 rotates, the female screw portion 42 advances and retreats in the axial direction of the shaft 41, and the contact portion 44 moves together with the female screw portion 42. The moving path of the contact portion 44 is on the track surface of the operation arm 10 that rotates within a predetermined angle range. Thus, when the contact portion 44 moves in the axial direction of the shaft 41 together with the female screw portion 42, the contact portion 44 contacts the operation arm 10 on the movement path. In the present embodiment, the contact portion 44 is located on the shield plate 30 side with respect to the operation arm 10. Therefore, when the contact portion 44 moves in a direction away from the shield plate 30, the contact portion 44 contacts the operation arm 10, and the operation arm 10 pushed by the contact portion 44 that moves further in this state moves away from the shield plate 30. To turn.

Next, adjustment of the size of the foraging opening 35 using the foraging opening adjusting device 1 will be described. When the operation arm 10 is rotated around the axis of the support shaft 11 in a direction away from the shield plate 30, the shield plate 30 is drawn toward the operation arm 10 via the connecting arm 20 (for example, FIG. The state shown in FIG. 3B is changed from the state shown in a). At this time, the connecting arm 20 rotates around the axis P1 and the axis P2 according to the positional relationship between the shield plate 30 and the operation arm 10.

A plurality of inclined slits 31 are formed in the shield plate 30, and guide pins 63 fixed to the vertical frame member 62 are inserted into the respective slits 31. Therefore, the shield plate 30 drawn to the operation arm 10 is guided by the inclination of the plurality of slits 31 and rises while maintaining a horizontal state. As the shield plate 30 is raised, the foraging opening 35 expands in the height direction. On the other hand, when the operation arm 10 is rotated in a direction approaching the shield plate 30, the shield plate 30 is lowered and the foraging opening 35 is narrowed in the height direction due to the movement opposite to the above (for example, FIG. ) To the state shown in FIG. That is, by rotating the operation arm 10 in the forward / reverse direction, the shield plate 30 can be raised and lowered to change the size of the foraging opening 35 in the height direction.

In FIG. 3A, since the guide pin 63 is at the upper end of the slit 31, the shield plate 30 is in the lowest position. On the other hand, in FIG. 3B, since the guide pin 63 is at the lower end of the slit 31, the shield plate 30 is in the highest position. The operation arm 10 can be rotated within a range between the angle shown in FIG. 3A and the angle shown in FIG.

Rotation of the operation arm 10 can be performed by rotating the shaft 41 as shown in FIGS. 4 (a) and 4 (b). When the shaft 45 is rotated by turning the handle 45, the female screw portion 42 and the contact portion 44 advance and retract in the axial direction of the shaft 41 as described above. In this embodiment, the contact part 44 contacts the operation arm 10 by moving the female screw part 42 away from the shield plate 30 (see FIG. 4A). In this state, when the shaft 41 is further rotated in the same direction, the female screw portion 42 moves further away from the shield plate 30, and the contact portion 44 presses the operation arm 10. Thereby, the operation arm 10 rotates around the axis of the support shaft 11 in a direction away from the shield plate 30 (see FIG. 4B).

Since the female screw portion 42 advances and retreats by screwing with the male screw, even if the shaft 45 is rotated by turning the handle 45, the female screw portion 42 moves only little by little. Thereby, the angle at which the operation arm 10 rotates can be easily finely adjusted by rotating the handle, and as a result, the height of the shield plate 30 can be finely adjusted.

In addition, by rotating the support shaft 11 by using a tool such as a wrench, the operation arm 10 is rotated in advance to some extent, and then the handle 45 is rotated to rotate the shaft 41 to thereby rotate the angle of the operation arm 10. May be finely adjusted.

As described above, according to the foraging opening adjusting device 1 of the present embodiment, the angle at which the operation arm 10 rotates can be finely adjusted by an extremely easy operation of rotating the handle 45 to rotate the shaft 41. Thus, the height of the shield plate 30 can be finely adjusted, and the size of the foraging opening 35 can be finely adjusted in the height direction.

Further, since the contact portion 44 presses the operation arm 10 when moving in a direction away from the shield plate 30, the height of the shield plate 30 when the shield plate 30 is raised can be finely adjusted. Therefore, the foraging opening adjusting device 1 can finely adjust the height of the shield plate 30 when expanding the size of the foraging opening 35 in the height direction as the chick grows.

In addition, the abutting portion 44 is located on the shield plate 30 side with respect to the operation arm 10, and the inclined shaft 41 has a lower end near the shield plate 30. Therefore, when the contact portion 44 is in contact with the operation arm 10, the contact portion 44 supports the operation arm 10 from below. Since the female screw portion 42 to which the contact portion 44 is fixed meshes with the male screw of the shaft 41, the contact portion 44 does not move unless the shaft 41 is rotated. Therefore, the contact portion 44 also has an action of holding the operation arm 10 in that state after finely adjusting the angle of the operation arm 10.

In the present embodiment, as shown in FIGS. 4A and 4B, a horizontally long slot 56 is formed in the base plate 51, and the slot 16 long in the axial direction is formed in the operation arm 10. Is formed. Thus, after finely adjusting the angle of the operation arm 10, the operation arm 10 and the base plate 51 are fastened with a nut or the like by fastening a bolt inserted through the long hole 16 and the long hole 56. Can be maintained (the height of the shield plate 30). As described above, since the angle of the operation arm 10 is also maintained by the contact portion 44, it is not necessary to firmly fasten the operation arm 10 and the base plate 51. Therefore, the operation arm 10 and the base plate 51 can be easily fastened by using a wing nut or the like that is fastened to the bolt by manual operation.

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

For example, in the above embodiment, the operation arm 10 is connected to the shield plate 30 via the long connection arm 20. However, the present invention is not limited to this. Even if the operation arm is directly connected to the shield plate, the shield plate can be moved up and down by the rotation of the operation arm. However, in this case, elements such as the operation arm and the shaft are brought close to the end of the shield plate. In the above embodiment, the operation arm 10 or the like can be positioned at a distance away from the end of the shield plate 30 by using the long connecting arm 20. Thereby, even if it is a case where food is supplied using the feeding feeder which reciprocates the bait bowl 70, the space which makes a feeding feeder stand by outside from the most end cage 60 can be secured.
