Position at the front end position of the slidable range. Further, when the pushing member 40 reaches the front end position, regardless of the deformation state of the bending deformation portion 23, the front end surface of the pushing member 40 (specifically, the front surface of the relay member 71) becomes the front end surface of the support pipe 11 (specifically, the front surface of the relay member 71). is located forward of the front surface of the front pipe 21 , and the capsule 90 is reliably ejected forward from the support pipe 11 .

If the front end surface of the pushing member 40 is positioned in front of the stepped surface 21D (see FIG. 5) of the front pipe 21 of the support pipe 11 within the slidable range of the pushing member 40, the capsule 90 by the front pipe 21 is released, more than half of the capsule 90 is pushed out from the support pipe 11 and separated from the support pipe 11 . Here, in the present embodiment, the position where the front end surface of the pushing member 40 is located forward of the front side of the stepped surface 21D of the front pipe 21 of the support pipe 11 is referred to as the "second slide position" (including the "front end position"). It is assumed that

As shown in FIG. 7, the capsule loading device 10 is provided with a lock mechanism 53 for locking the pushing member 40 in the first slide position. The lock mechanism 53 includes, for example, a lock bar 50 hinged to the lower end (tip) of the second handle 31 . The lock bar 50 is formed, for example, by bending a metal rod, and has a ring portion 50B at one end thereof, and an engagement member extending in a direction orthogonal to the entire lock bar 50 at the other end. A joint 50C is provided. A tapered surface is formed at the tip of the engaging portion 50C.

A hinge member 51 is connected to the ring portion 50B of the lock bar 50 . The hinge member 51 is formed by bending a metal rod or the like, and is provided with a ring portion 51B wound so as to pass through the ring portion 50B of the lock bar 50 at one end as shown in FIG. Also, the other end of the hinge member 51 is a male screw 51A. The male screw 51A is screwed into the mounting hole 35D in the cover 35 of the first handle 30 to fix the hinge member 51 to the lower end of the second handle 31, and the inner space of the ring portion 51B is oriented in the front-rear direction. there is Thereby, the lock bar 50 is hinged to the first handle 30 so as to rotate in the front-rear direction and the up-down direction. Then, as shown in FIG. 7, when the pushing member 40 is arranged at the first slide position, when the engaging portion 50C of the lock bar 50 is inserted into the engaging hole 35E of the second handle 31, frictional engagement occurs. The engaging portion 50C is retained in the engaging hole 35E, and the lock bar 50 is maintained in a locked state extending between the lower ends of the first handle 30 and the second handle 31. As shown in FIG. As a result, the pushing member 40 is locked at the first slide position.

In this embodiment, the lock bar 50 is bridged between the rear end portion of the pushing member 40 and the lower end portion of the first handle 30 via the second handle 31. 50 may be bridged between the rear end portion of the pushing member 40 and the lower end portion of the first handle 30 via the pressing cap 32, or the lock bar 50 may extend between the second handle 31 and the pressing cap. It may be arranged to span between the rear end portion of the pushing member 40 and the lower end portion of the first handle 30 without passing through 32 or the like.

The configuration of the capsule inserting device 10 of this embodiment has been described above. Next, the effects of this capsule injection device 10 will be described. To use the capsule inserting device 10, as shown in FIG. is spanned and the pushing member 40 is locked in the first slide position. Then, the capsule 90 is pushed deep into the capsule receiving portion 20 from the tip of the support pipe 11 and is held in the capsule receiving portion 20 by frictional engagement.

In this state, for example, the first handle 30 as the first operating section of the capsule inserting device 10 and the second handle 31 or the pressing cap 32 as the second operating section are held with one hand and the other hand of the operator. is grasped by Then, when the assistant opens the mouth of the cow 100 , the tip of the capsule feeding device 10 is inserted into the mouth of the cow 100 .

Here, when inserting the tip of the capsule injection device 10 into the mouth of the cow 100, the cow 100 will reject it and move its neck, and the position of the hand holding the capsule injection device 10 will change in response to this movement. can be considered. However, in the cow 100 of the present embodiment, the lock bar 50 is positioned away from the hand that grips the first handle 30, the second handle 31 and the pressing cap 32. A situation in which the capsule 90 is ejected from the capsule feeding device 10 in front of the throat or outside the mouth of the cow 100 when the lock is released by a hand and the pushing member 40 is pushed thereon is prevented. be prevented.

In the absence of an assistant, for example, the first handle 30 of the capsule loading device 10 is held with one hand and the mouth of the cow 100 is opened with the other hand. A portion may be inserted into the cow's 100 mouth. After that, the first handle 30 and the second handle 31 or the pressing cap 32 can be grasped with both hands.

After the tip of the capsule injection device 10 is pushed into the mouth of the cow 100, the entire capsule injection device 10 is further pushed from there and inserted into the cow's 100 throat or esophagus. At that time, the cow 100 may move its head and resist, but the capsule feeding device 10 has the bending deformation part 23 and bends following the posture of the head of the cow 100. reduce the burden on By holding the first handle 30 and the second handle 31 of the capsule charging device 10, the operator can easily operate the capsule charging device 10 while standing on the side of the cow 100.

As shown in FIG. 3 , when the tip of the capsule injection device 10 is inserted into the throat or esophagus of the cow 100 , the capsule injection device 10 is stabilized with respect to the cow 100 . Then, the first handle 30 is held with only one hand, and the locking by the lock bar 50 is released with the other hand. Then, the second handle 31 or the pressing cap 32 is gripped with the other hand, and the pushing member 40 is pressed against the support pipe 11 . When the pushing member 40 is moved to the second slide position by the pressing operation, the capsule 90 is discharged from the capsule feeding device 10 into the esophagus of the cow 100 and is put into the stomach 100S.

Here, when pushing the pushing member 40 described above, the first handle 30 and the second handle 31 may be grasped with both hands to perform the pushing operation, or the first handle 30 may be held with one hand. The pressing operation may be performed by holding the pressing cap 32 and pressing the pressing cap 32 with the palm of the other hand. If the pressing cap 32 is used, the pushing member 40 can be pushed straight in the axial direction of the support pipe 11, and the pushing operation can be performed more smoothly than when the second handle 31 is used. Furthermore, since the pressing cap 32 has a pressing surface that is a rear end surface that is wider than the rear end surface of the pushing member 40, the burden on the operator can be reduced.

Also, even if the pushing member 40 moves forward at once with respect to the support pipe 11, the compression coil spring 49 is sandwiched between the support pipe 11 and the second handle 31 to absorb the impact, thereby This reduces the burden on people. In addition, since the pushing member 40 is pushed back to the middle or the end of the movable range by the elastic force of the compression coil spring 49, preparation work for inserting the capsule 90 into the next cow 100 can be efficiently performed.

After the ejection of the capsule 90 by the pressing operation of the pushing member 40 is completed, the capsule loading device 10 is taken out from the cow 100 and the above operation is repeated to load the capsule 90 into a plurality of cows 100 . Then, as described above, information relating to the state of the stomachs 100S of the cows 100 is wirelessly transmitted from the capsules 90 to the outside, and the health conditions of the cows 100 can be managed.

As described above, the capsule injection device 10 of this embodiment can be operated with both hands using the first handle 30 as the first operating section and the second handle 31 or the pressing cap 32 as the second operating section. Moreover, the first operating portion (first handle 30) is arranged at the rear end portion of the support pipe 11, while the second operating portion (second handle 31, pressing cap 32) extends rearward from the support pipe 11. Since it is arranged at the rear end of the pushing member 40 and the first operating part and the second operating part are separated, the operating force for countering the swinging motion of the cow 100 can be easily applied to the capsule feeding device 10. transmitted. As a result, the operation of inserting the capsule injection device 10 into the mouth of the cow 100, the operation of pushing out the capsule 90 from the capsule injection device 10, and the like can be stably performed. In particular, the operation of the capsule injection device 10 for a large animal such as a cow 100 that cannot be lifted with one hand is stabilized. In addition, since the capsule loading device 10 has the bending deformation part 23 and bends following the posture of the head of the cow 100, the burden on the cow 100 is reduced and the work of inserting the capsule into the cow 100 is facilitated.

Furthermore, since the capsule inserting device 10 of the present embodiment has a simple structure in which the pushing member 40 is slidably fitted to the support pipe 11, problems such as foreign matter being caught in the movable portion are less likely to occur. Further, since the supporting pipe 11 and the pushing member 40 are prevented from rotating by the engagement between the groove 18 and the projection 45 as the anti-rotation engaging portion, the relative rotational positional relationship between them is constant. The relative rotational positional relationship between the first handle 30 and the second handle 31 also becomes constant, and the operation of the capsule injection device 10 using the first handle 30 and the second handle 31 is stabilized. Furthermore, since the groove 18 of the support pipe 11 and the protrusion 45 of the push member 40 are engaged with each other, the groove 18 and the protrusion 45 are not provided, and the inner surface of the support pipe 11 and the outer surface of the push member 40 are not provided. are circular, the guide function of the support pipe 11 for the sliding movement of the pushing member 40 is enhanced, and the sliding operation itself of the pushing member 40 is also stabilized. Moreover, as shown in FIG. 6, the grooves 18 and the ridges 45 are in line contact, so the slide resistance is suppressed.

In addition, in the capsule injection device 10 of the present embodiment, the first handle 30 and the second handle 31 can be moved and fixed to arbitrary positions around the axis of the support pipe 11 and the pushing member 40. The relative rotational positional relationship between the handle 30 and the second handle 31 can be arbitrarily changed according to the preference of the operator. This improves work efficiency.
