Further, both ends of the intestine set pipe 2 are open.

  As shown in an enlarged view in FIG. 2, a coupler plug 5 is provided on the rear end side of the intestine set pipe 2. When this coupler plug 5 is provided, when the intestinal tract 4 is fitted into the intestinal set pipe 2, a hose (not shown) is connected to the coupler plug 5 and water is allowed to flow, so that the inside of the intestinal tract 4 is washed and fitted. This is preferable because the work can be performed.

  The rear end side where the coupler plug 5 is provided is a side from which the inverted intestinal tract 4 is released during the inversion process of the intestinal tract 4, and is also a side to be held by the holder 6. On the rear end side, a flange 7 is provided with a gap from the coupler plug 5. The intestinal set pipe 2 is attached to the gantry 1 by holding a portion between the coupler plug 5 and the collar portion 7 with a holding tool 6 that is detachably held. The heel part 7 allows the intestinal set pipe 2 to be held at a certain position by the holder 6 and prevents the intestinal tract 4 fitted in the intestine set pipe 2 from entering the area held by the holder 6. Is for.

  The holder 6 is attached to the gantry 1, and for example, a toggle clamp as shown in FIG. 3 can be used. Furthermore, the holding | maintenance state of the intestine set pipe 2 shown by FIG. 3 is demonstrated. The intestinal set pipe 2 has a rear end portion (a region between the coupler plug 5 and the collar portion 7) placed in a recess of a receiving seat 8 attached to the gantry 1, and a presser arm 9 of a holder 6 that is a toggle clamp. The holding part 10 is held by being pressed from above. When the lever 11 of the holder 6 is lifted upward as indicated by an arrow A, the presser arm 9 is lifted upward as indicated by an arrow B so that the holding state can be easily released. Conversely, if the lever 11 of the holder 6 is pushed down with the rear end portion of the intestine set pipe 2 being placed in the recess of the seat 8, the presser arm 9 is lowered to the holding state shown in FIG. Further, when the rear end of the intestine set pipe 2 is placed in the recess of the seat 8, if the side surface of the collar 7 is brought into contact with the side surface of the seat 8, The pressing position can be made constant. In addition, in FIG. 3, the collar part 7 is shown with the broken line for convenience of illustration.

  The distal end side of the intestinal set pipe 2 is the side where the intestinal tract 4 is drawn in order to be reversed, and the air nozzle 3 provided on the distal end side has an ejection hole 13 having a diameter smaller than the inner diameter of the intestinal set pipe 2 at the distal end. Yes. The ejection hole 13 of the air nozzle 3 faces the center of the opening on the distal end side of the intestine set pipe 2. That is, when the rear end side of the intestine set pipe 2 is held by the holder 6 as described above, the central portion of the opening on the front end side of the intestine set pipe 2 and the ejection hole 13 that opens at the front end of the air nozzle 3 are formed. The holding position of the intestine set pipe 2 by the holder 6 and the position of the air nozzle 3 are adjusted so as to face each other. The air nozzle 3 ejects compressed air supplied from a separately provided compressor (not shown) from the ejection hole 13 in the axial direction of the intestinal set pipe 2 through the air conditioner 12 attached to the gantry 1. To do. The air conditioner 12 is a device for adjusting the compressed air supplied to the air nozzle 3, and includes a drain catcher, a filter, a regulator, a mist separator, and the like.

  The compressed air flow ejected from the ejection hole 13 of the air nozzle 3 is ejected as a flow having a diameter smaller than the inner diameter of the intestinal set pipe 2, thereby causing the intestinal tract 4 to be pulled in later. The diameter of the ejection hole 13 of the air nozzle 3 is preferably 1/3 to 2/3 of the inner diameter of the intestine set pipe 2 in order to make it easy to obtain the action of drawing in the intestinal tract 4 described later. 5 is more preferable. In addition, the retraction action of the intestinal tract 4 described later is greatly influenced by the distance between the opening on the distal end side of the intestinal set pipe 2 and the ejection hole 13 at the distal end of the air nozzle 3. In order to facilitate the adjustment of the interval, the air nozzle 3 is preferably adjustable in the axial direction of the intestine set pipe 2.

The foot switch 16 opens and closes an on-off valve provided in a flow path of compressed air to the air nozzle 3, and is supplied with compressed air when stepped on, and is stopped when the foot is released. ing.

  Next, the intestinal tract reversal method for animals according to the present invention, which can be performed using the above-described apparatus, will be described in each step, and the principle of reversal of the intestinal tract 4 in the present invention will be described.

(1) Preparatory process First, the preparatory process which fits the intestinal tract 4 of an animal in the outer peripheral axis direction of the intestine set pipe 2 removed from the mount frame 1 is performed. This fitting is performed by inserting the intestinal tract 4 cut to a predetermined length from the distal end side of the intestinal set pipe 2 and setting it so as to cover the outer periphery of the intestinal set pipe 2 in the axial direction. Although a plurality of intestinal canals 4 are set, the number of the intestinal canals can be freely determined as long as the intestinal canal 4 can be held on the tip side from the buttocks 6 of the intestinal set pipe 2. The cut length of the intestinal tract 4 may be determined from the ease of the reversal process and the ease of the subsequent process, but is usually about 20 cm to 40 cm. Further, when a hose is connected to the coupler plug 5 provided on the rear end side of the intestinal set pipe 2 and the intestinal tract 4 is fitted while flowing water, the water flowing out from the opening on the front end side of the intestinal set pipe 2 Thus, the fitting operation of the intestinal tract 4 can be performed while washing away the filth in the intestinal tract 4.

(2) Intestinal Set Pipe Attaching Step Next, the rear end side of the intestinal set pipe 2 into which the intestinal tract 4 is fitted is held by the holder 6, and the center of the opening on the distal end side of the intestinal set pipe 2 and the air nozzle 3 The ejection hole 13 is opposed to the axial direction of the intestinal set pipe 2.

(3) Inversion process The compressor (not shown) is operated, and the foot switch 16 is stepped on to fit into the intestinal set pipe 2 while ejecting compressed air from the ejection hole 13 of the air nozzle 3 in the axial direction of the intestinal set pipe 2. The intestinal canal 4 is gradually shifted to the distal end side of the intestinal set pipe 2. This movement of the intestinal tract 4 is most easily performed manually.

  By the way, when the center part of the opening part of the front end side of the intestine set pipe 2 and the ejection hole 13 of the air nozzle 3 face each other, and compressed air is ejected from the ejection hole 13 in the axial direction of the intestine set pipe 2, it was ejected. The flow of compressed air flows into the intestine set pipe 2 while surrounding air is involved. For this reason, as shown by an arrow C in FIG. 4A, an air flow drawn into the intestine set pipe 2 from the outer peripheral side of the opening on the distal end side of the intestine set pipe 2 is generated. When the intestinal tract 4 is gradually shifted and the end of the intestinal tract 4 located closest to the distal end side of the intestinal set pipe 2 starts to be discharged from the distal end side of the intestinal set pipe 2, the intestinal set is caused by the air flow indicated by the arrow C above. It is drawn into the pipe 2 and enters a state as shown in FIG. The part of the intestinal tract 4 drawn into the intestinal set pipe 2 is in an inverted state in which the front and back are inverted. When the intestinal tract 4 is further shifted, as shown in FIG. 4 (c), the intestinal tract 4 is further drawn in such a way that it is caught in the flow of the compressed air from the ejection holes 13 of the air nozzle 3, and finally the cut intestinal tract 4 is entirely removed. It is drawn into the intestine set pipe 2 and reversed.

(4) Recovery process After the entire intestinal tract 4 is drawn into the intestine set pipe 2, it is pushed by the flow of compressed air from the ejection hole 13 of the air nozzle 3 and moves in the intestine set pipe 2, It is discharged from the rear end side of the pipe 2. If the cover 14 is provided at a position facing the opening on the rear end side of the intestine set pipe 2, it is possible to receive the intestinal tract 4 that is pushed out by the compressed air and jump out, thereby preventing scattering. If the collection container 15 is provided below the cover 14, the treated intestinal tract 4 can be collected in the collection container 15.

  In the method of the present invention, a plurality of intestinal set pipes 2 are prepared, and in the preparing step, a plurality of intestinal set pipes 2 into which the intestinal canal 4 is fitted are prepared, and the intestine set pipe attaching step, inversion are sequentially performed. If it is made to use for a process and a collection process, work efficiency will improve. In addition, when the foot switch 16 is provided, it is possible to stop and restart the supply of compressed air to the air nozzle 3 when replacing the intestinal set pipe 2 without dirtying the hands, so that work efficiency is improved.
