In order to lock the closed state of the opening / closing door 20 in a state where it is inserted and supported from above, the locking pieces 110, 110 of the door opening / closing device 100 attached to the upper ends of the columns 12, 12 on both sides are supported. 5 is tilted forward in the direction of the arrow in FIG. 5 and rotated to the downward locked position.

  By simply tilting the left and right lock pieces 110 and 110 forward with one touch, as shown in FIGS. 2 and 5, the tip of each downward lock piece 110 presses the support shafts 22 and 22 on the door 20 side from above. Thus, the closed state of the open / close door 20 is securely locked. In addition, as shown in FIG. 5, each lock piece 110 has an inclined posture in which the distal end portion 110 b faces rearward, so that the above-described lock is more reliably secured and there is no possibility that the lock is unexpectedly released. Therefore, even if the breeding pig in the breeding fence 10 rushes into the open / close door 20 and the support shafts 22 and 22 are about to come out upward, it is pressed by the lock piece 110 from above, and the open / close door 20 may be opened or removed. In addition, as a result, there is no fear that the domestic pig is injured or scratched by the protrusion (support shaft portion 21) of the door 20.

  One of the left and right lock pieces 110, 110 is lifted with one hand to be in a standing posture, and by releasing one of the lock states, the opening / closing door 20 is opened as indicated by a dotted line on the right side of the passage in FIG. Alternatively, the opening / closing door 20 can be opened with respect to the left side of FIG.

  In either case, the width of the opening / closing door 20 is substantially the same or larger than the passage width, so that when the opening / closing door 20 is opened to the left side of the passage, the right side of the passage is blocked, When the opening / closing door 20 is opened on the right side, the left side of the passage is blocked and the breeding pig can be guided smoothly.

According to the door opening and closing apparatus 100 of the present embodiment, the following effects can be obtained.
(1) The closed state of the door 20 can be easily locked and the locked state can be easily released by one-touch operation of both the lock pieces 110 and 110. Therefore, the operator can easily open and close the open / close door 20.
(2) An inclined posture in which the tip portion 110b of the lock piece 110 faces rearward at the lock position of the downward lock piece 110, and an inclined posture in which the tip portion 110b of the lock piece 110 faces rearward in the standing posture of the upward lock piece 110. Therefore, the locked state and the unlocked state are ensured. Therefore, for example, the lock piece 110 facing downward is inadvertently unlocked, or the lock piece 110 in the standing posture is inadvertently rotated forward to cause the lock piece 110 to stand up again. I will not let you.
(3) The operator can easily recognize the lock piece 110 in the downward lock position or the lock piece 110 in the upward standing posture from the side of the passage or from a distance. The lock can be reliably recognized from a distance, or the lock piece 110 in the standing state can be easily recognized from the forgotten lock of the open / close door 20 and dealt with promptly. Thereby, breeding management by an operator can be facilitated.

  Thus, according to the present invention, it is possible to realize a door opening / closing device that can lock the opening / closing door of the rearing fence in a closed state and can easily release the locking with one touch.
