The present invention relates to an automatic traveling mixer feeder provided with a feeding scraper for returning the feed scattered to the side away from the dairy cow in the feeding tank when the dairy cow ingests the feed (feed). It is a thing.

When breeding dairy cows in free stall or free barn, the feeding management is standard TMR (Total Mixed Ration) in the barn's feeding tank, and dairy cows are fed. , By ingesting a fully formulated feed in one place.

As one of the barns where feeding management is performed by TMR, there is a rectangular free stall structure shown in FIG. In this barn CH, a large number of bed groups B _{1 to} B ₅ of the dairy cow group are arranged along the longitudinal direction of the barn CH, _{and between the bed groups B 1} and the same B ₂ and B ₃ , the barn _{A passage T 1} is formed along the longitudinal direction of the CH, _{and a passage T 2} along the lateral direction of the barn CH is formed between the beds B ₂ and B ₄ and the same B ₃ and B _5. It is formed. On the opposite side of the bed group B _{4 from} the bed group B ₅ , another bed group B ₆ is arranged in series with the respective bed groups B ₄ and B ₅ via the passage T _{3 , and the bed groups B 3} and B _{5 are arranged.} On the opposite side of the passage T _{2 in} the above, another passage T _{4 is formed, and further, a passage T 5} is formed in the portion of the barn CH facing the bait tank 42 described later over almost the entire length of the barn CH. ing. Further, in one portion of the barn CH divided into two along the longitudinal direction, a milking chamber 41 is arranged so as to project in the lateral direction with respect to the barn CH.

On the side opposite to the bed group B ₁ and the milking chamber 41 along the lateral direction of the barn CH, the range indicated by reference numeral A in FIG. 1 extends over almost the entire length of the barn CH in the longitudinal direction. Feeding ground) 42. The feeding tank 42 is formed by a flat feeding tank floor 44 on the outside of the fence body 43 via a fence body 43 (see FIGS. 1 and 2) from which dairy cows cannot exit, and is parallel to the feeding tank 42. The feed (feed) F is automatically supplied to the feeding tank 42 by the automatic traveling mixer feeding machine (hereinafter, may be simply abbreviated as "mixer feeding machine") M that travels as the feed tank 42. The mixer feeder M has a structure in which the feed F charged inside is stirred and travels, and is guided by a pair of rails 45 laid parallel to the feed tank 42. As shown in FIG. 9, the pair of rails 45 are laid on the rail floor 46, which is slightly higher than the flat bait tank floor 44. In FIG. 9, K indicates the height difference between the feeding tank floor 44 and the rail floor 46.

In the mixer feeder M, the feed F adjusted by the feed cooking facility D arranged along the lateral direction of the barn CH at the end on the side of the milking chamber 41 in the longitudinal direction of the barn CH is delivered by the transport conveyor 51. , It is put into the feed tank 3 of the mixer feeder M waiting at the departure position of one end of the rail 45. The feed cooking facility D is provided with, for example, the first to third input hoppers H _{1 to} H ₃ , and the first hopper H ₁ is charged and stored with pre-cut grass for one day, and the second and second hoppers are stored. each hopper H _2, H ₃ of 3, one day of silage and Eco feed respectively is turned and storage. _{Further, each of the feed raw materials in the first to third} hoppers H1 to H3 is discharged onto the conveyor 51 at a time set by the 24-hour timer, and the feed material is discharged onto the conveyor 51. It is put into the feed tank 3 of the mixer feeder M from the tip portion. If necessary, water is supplied from the water source into the feed tank 3 of the mixer feeder M.

As shown in FIGS. 1 to 3, the mixer feeder M has a feed tank 3 mounted on a pedestal 2 having two pairs of front and rear wheels 1 in a pair via a load cell (not shown). By doing so, the weight of the feed F charged into the feed tank 3 can be measured. In the feed tank 3, an auger screw 4 for stirring the fed feed F is arranged. The feed tank 3 has a square shape when viewed from the front, but has an isosceles trapezoidal shape when viewed from the side, so that the overall shape becomes an irregular inverted cone shape, and the capacity of the feed F is increased. ing. The auger screw 4 has a configuration in which a spiral blade 6 is integrally attached to a vertical rotation shaft 5, and the spiral blade 6 has an outer diameter that gradually increases toward the bottom, so that the bottom of the feed tank 3 is formed. It is easy to discharge the feed F to the outside from the portion close to. A drive motor for driving and rotating the vertical rotation shaft 5 of the auger screw 4 in a space adjacent to the feed tank 3 along the traveling direction of the mixer feeder M on the gantry 2, and a transmission mechanism for transmitting the power thereof. A part is arranged and covered with a device covering cover 7.

A feed discharge port 12 is formed by sliding the shutter 11 upward on the side surface of the feed tank 3 facing the feed tank 42 and close to the bottom of the feed tank 3, and the feed tank 3 is said to have the same. A guide chute 13 for delivering the feed F discharged from the feed discharge port 12 to the portion of the feed tank 42 is provided in a portion below the lower end of the feed discharge port 12. The guide chute 13 is arranged along a direction orthogonal to the traveling direction of the mixer feeder M so that the tip thereof is lower than the base end. The shutter 11 is guided by a pair of shutter guides 14 provided along the vertical direction inside the plate portions 13a on both sides of the guide chute 13 to move up and down.

The shutter 11, which is guided by the pair of shutter guides 14 and moves up and down, is integrally provided on the front surface of the shutter 11 with a pair of racks provided in the height direction at predetermined intervals in the horizontal direction, and the pair. It is rotatably supported inside a rack support member horizontally fixed to the shutter guide 14, and is raised and lowered by a rack and pinion mechanism including a pair of pinions that mesh with the rack. That is, the pinion shaft to which the pinions are integrally attached is driven and rotated by a drive motor, so that the shutter 11 is raised and lowered, and the feed discharge port 12 is opened and closed. The mechanism for opening and closing the shutter 11 is not directly related to the present invention characterized in that the mixer feeder M is provided with a feeding scraper, and thus the illustration is omitted.

Then, the feed adjusted by the feed cooking facility D is placed in the feed tank 3 of the mixer feeder M waiting at the position of the end portion of the pair of rails 45 on the side of the milking chamber 41 (hereinafter referred to as “departure position”). When F is charged, the feed tank 3 is filled with feed F. Then, when a plurality of preset times of the day are reached by the timer, the mixer feeder M waiting at the departure position starts traveling in the forward direction and reaches the position of the feeding tank 42. As the vertical rotation shaft 5 of the auger screw 4 starts rotating and the shutter 11 moves upward, the feed discharge port 12 opens, and as shown in FIGS. 9 (a) and 10 (a), The feed F is supplied (feeding) in a heaped shape while maintaining a constant width to the feeding tank 42 provided outside the fence body 43 of the barn CH via the guide chute 13. When the mixer feeder M reaches a slightly front side of the forward end position, which is the end opposite to the departure position of the pair of rails 45, the rotation of the vertical rotation shaft 5 of the auger screw 4 is stopped and the rotation of the vertical rotation shaft 5 is stopped. The shutter 11 moves downward to close the feed discharge port 12, and thereafter, the mixer feeder M moves slightly forward and then stops at the forward end position.

When a large number of dairy cows C in the barn CH learn that the feed F has been supplied to the feeding tank 42, they take out the head and neck from between the fences of the fence body 43 and ingest the feed F of the feeding tank 42. After the ingestion of the feed F by the dairy cow C, the feed F supplied to the feeding tank 42 in a heap shape with a constant width not only breaks the heap state, but is also shown in FIGS. 9 (b) and 10 (b). As a result, when the feed F is ingested by the dairy cow C, the feed F is scattered. Of the amount of feed F that is scattered, there is no problem in that it is scattered to both sides, but there is a large proportion of it that is largely scattered forward with reference to dairy cow C, and this feed that is scattered forward (hereinafter referred to as "scattered feed"). ) F'cannot be ingested by dairy cow C at a distance, so it is returned to the feeding tank 42 by some means so that it can be ingested again.

Conventionally, in the operation of returning the scatter feed F'to the feeding tank 42, for example, a warp plate-shaped member is attached to a moving vehicle moving along a rail laid on the side of the feeding tank, and the moving vehicle is fed. A technique for moving along a tank is known (Patent Document 1). Further, the scraped feed F'is returned to the feeding tank 42 by attaching a scraper to an agricultural tractor or a heavy machine owned by a dairy farmer and traveling. However, all means use mobile machinery other than the mixer feeder that supplies (feeds) feed to the feeding tank, and from the aspect of dairy equipment, the equipment becomes excessive and the cost increases. At the same time, after feeding several times a day, another mobile machine must be carried to the part near the feeding tank of the barn each time, so the efficiency of work in the barn is also poor.

Japanese Unexamined Patent Publication No. 11-89470

The present invention uses a mixer feeding machine owned by a dairy farmer to return the scattered feed to the feeding tank, thereby suppressing the occurrence of excess equipment and efficiently performing the feeding returning work itself. The challenge is to make it.

In the invention of claim 1 for solving the above-mentioned problems, a flat feeding tank having a predetermined width is provided along a fence body at a straight portion of the outer edge of the barn, and automatic running for supplying feed to the feeding tank is provided. The type mixer feeder is arranged close to the feeding tank so that it can travel in a straight line back and forth automatically.
A vertical plate-shaped bait gathering scraper whose lower end edge is arranged in contact with the extension surface of the bait tank floor is rotatably provided in a horizontal plane at an appropriate position on the gantry of the automatic traveling mixer feeder. The gantry is provided with each stopper portion that regulates both rotating ends of the feeding scraper, so that the feeding scraper with respect to the traveling direction of the automatic traveling mixer feeder during the feeding work and the feeding work. The tilt angle of each is determined,
Due to the reciprocating travel of the automatic traveling mixer feeder, the feeding scraper is rotated in opposite directions due to the traveling resistance to the feeding tank floor and abuts on each of the stopper portions, so that the feeding tilting position and the feeding tilting position The bait scattered forward from the bait tank with respect to the dairy cow comes into contact with the bait gathering scraper slanted at the bait gathering inclined position and moves along the longitudinal direction thereof. It is characterized in that it is configured to be returned to the feeding tank.

According to the invention of claim 1, in both the feeding operation and the feeding operation, the vertical plate-shaped feeding scraper is in a state where the lower end edge thereof is in contact with the extension surface of the feeding tank floor, that is, the feeding. Since the automatic traveling mixer feeder is rotatably arranged in the horizontal plane on the pedestal of the automatic traveling mixer feeder in a state where the traveling resistance is generated between the extension surface of the tank floor, the automatic traveling mixer feeder moves forward and backward. Regardless of the direction of travel, the end of the bait tank in the bait gathering scraper is arranged diagonally rearward with respect to the opposite end with respect to the travel direction of the automatic traveling mixer feeder. NS. As a result, when the feeding scraper is arranged in front of the feed discharge port in the forward direction of the automatic traveling mixer feeder during the feeding operation, the feed supplied to the feeding tank behind the feeding scraper. When the feed scraper is placed behind the feed outlet in the forward direction, there is no risk of interference with the feed tank, and the tip portion does not interfere with the feed already supplied to the feed tank. By providing the stopper portion so that the feeding scraper can be rotated and arranged in an inclined manner, the feeding scraper does not interfere with the supplied feed, and the feeding tank is irrespective of the presence of the feeding scraper. Feed can be smoothly supplied to.

Starting from the starting position, when the feeding scraper reaches the end opposite to the starting position in the feeding tank, the feed outlet is closed to stop the feeding, and the automatic running mixer feeding machine is used by dairy cows. Stop at that position until the prescribed amount of feed has been consumed. When a dairy cow ingests a predetermined amount of feed, the feed is scattered on the extension surface of the feeding tank bed when the dairy cow ingests the feed. When the amount of the scattered feed reaches a predetermined amount, the automatic traveling mixer feeder stopped at the advancing end position on the opposite side of the starting position is started to reverse travel (reverse traveling) toward the starting position. At the forward end position, the automatic traveling mixer feeder travels in the reverse direction, and the traveling resistance of the feeding scraper with respect to the extension surface of the feeding tank floor causes the feeding scraper to travel forward around the rotation fulcrum. The bait gathering scraper is largely rotated until it comes into contact with a stopper portion different from the stopper portion with which the bait gathering scraper was in contact, and the tip of the contact feeding feed gathering scraper is arranged rearward with respect to the reverse running direction to attract the bait. The scraper is placed in the feeding tilt position. That is, by changing the traveling direction of the automatic traveling mixer feeder, the feeding scraper is automatically changed in the inclined posture according to the traveling resistance with respect to the extension surface of the feeding tank floor. As a result, when the automatic traveling mixer feeder travels in the opposite direction, the scattered feed scattered on the extension surface of the feeding tank floor comes into contact with the feeding scraper arranged at the feeding inclined position, and then the feed is concerned. It is moved to the side of the feeding tank along the feeding scraper and returned to the feeding tank.

The invention of claim 2 is the invention of claim 1, wherein the feed gathering scraper is arranged behind the feed discharge port in the gantry with respect to the forward direction at the time of feeding by the automatic traveling mixer feeder. The tip of the feeding inclined position of the feeding scraper in a plan view is characterized in that it is arranged at a position that does not reach the heap-shaped feed already supplied to the feeding tank.

According to the invention of claim 2, even when feeding to the feeding tank by the automatic traveling mixer feeding machine, the feeding scraper does not interfere with the feed (feed) already supplied to the feeding tank, so that the feeding scraper is used. Does not interfere with the feed supply, and the feed can be smoothly supplied to the feed tank.

The invention of claim 3 is for laying a rail on which each wheel of the automatic traveling mixer feeder travels on the side of the feeding tank floor opposite to the fence body in the invention of claim 1 or 2. The rail floor is formed at a position slightly higher than the bait tank floor.
The portion of the feeding scraper that interferes with the rail floor is characterized in that the portion that interferes with the rail floor is cut out in order to avoid the interference.

The rail floor of the self-driving mixer feeder provided in the barn is often provided slightly higher than the surrounding portion from the viewpoint of facilitating cleaning and the like. According to the invention of claim 3, the presence of the notch can avoid interference between the scraper and the rail floor.

In the present invention, a vertical plate-shaped bait gathering scraper whose lower end edge is arranged in contact with the extension surface of the bait tank floor is rotatably provided in a horizontal plane at an appropriate position on the gantry of the automatic traveling mixer feeder. Moreover, by providing each stopper portion that regulates both rotating ends of the feeding scraper on the gantry, the automatic traveling mixer feeding machine with respect to the traveling direction during the feeding operation and the feeding operation. The inclination angles of the bait gathering scrapers are determined respectively, and the reciprocating travel of the automatic traveling mixer feeder causes the bait gathering scrapers to rotate in opposite directions due to the traveling resistance to the bait tank floor and hit each of the stopper portions. By being in contact with the feeding inclined position and the feeding inclined position, the feed scattered forward from the feeding tank to the dairy cow is sent to the feeding scraper inclined at the feeding inclined position. Since the bait is contacted and moved along the longitudinal direction of the bait tank and returned to the bait tank, the bait is brought to the extension surface of the bait tank when traveling in the reverse direction at the forward end position of the automatic traveling mixer feeder. Since the feeding scraper is automatically changed to the feeding or feeding tilted position due to the running resistance with the scraper, the feeding tank is fed without the need to change the tilting position of the feeding scraper. In addition, the automatic running mixer feeding machine owned by the dairy farmer can be used as it is, that is, the feeding of the scattered feed can be automatically performed without using a dedicated feeding device or a heavy machine.

It is a plan layout view of the barn CH of a free stall structure. It is a perspective view of the mixer feeding machine M provided with the feeding scraper S which concerns on this invention. Similarly, it is a front view which the part of the feed tank 3 was broken. It is also a plan view. It is a perspective view of the portion of the feed gathering scraper S attached to the gantry 2 of the mixer feeder M via an attachment 31 at the rear end portion. It is also an exploded perspective view. It is also a plan view. It is also a front view. (A), (b), and (c) are plan views showing the action of the feeding scraper S provided in the mixer feeder M during feeding, standby at the forward end position, and feeding, respectively. .. (A), (b), and (c) are side views immediately after feeding, after ingestion of feed F by dairy cow C, and after reconciliation of scattered feed F', respectively.

Hereinafter, the present invention will be described in more detail with reference to examples. An embodiment of the present invention is shown in FIGS. 1 to 8, and the vertical plate-shaped feed gathering scraper S has a forward direction Q in the gantry 2 of the mixer feeder M as shown in FIGS. 2 to 6. It is rotatably attached to the rear end portion along the line and on the side of the feed discharge port 12 in a horizontal plane via an attachment 31. As shown in FIGS. 5 and 6, the feeding scraper S is provided at the base end of a horizontally long rectangular scraper main body 21 having a large short-length ratio, and is a feeding inclination which is a position where the feeding scraper S is arranged at the time of feeding. A stopper plate 22 for determining the position (P _{2) is integrally attached.} The stopper plate 22 is not a portion linearly extended with respect to the scraper main body 21, but is integrally attached so as to form a large obtuse angle in a plan view in relation to the second stopper surface 38 described later. There is. As shown in FIG. 8, the scraper main body 21 is arranged at a position where it does not interfere with the rail 45 on the side of the fence body 43 in a plan view, and only the stopper plate 22 is arranged at a position where it interferes with the rail 45. The lower end portion of the stopper plate 22 that interferes with the rail 45 is notched in a square shape to form a notched portion 22a. At both ends of the scraper body 21 along the longitudinal direction, the contact scraper body F'is facilitated sliding with respect to the scatter feed sliding surface 21a, and the bending strength of the contact scraper body 21 is improved. The bent piece 21b is bent so as to form an obtuse angle on the side of the scatter feed sliding surface 21a. At the time of feeding the scatter feed F', the lower scatter feed sliding surface 21a is in sliding contact with the extension surface of the feed tank 42, so that running resistance is generated. At the base end portion (the portion on the side where the stopper plate 22 is continuously provided) of the surface opposite to the scatter feed sliding surface 21a of the scraper main body 21, the scraper main body 21 is close to each of the bent pieces 21b which are up and down in the arranged state. The pair of mounting plates 23 are integrally mounted along the longitudinal direction of the scraper main body 21 by means such as welding. The distance between the inner surfaces of the pair of mounting plates 23 corresponds to the distance between the outer surfaces of the upper and lower stopper plates 34 forming the stopper body 33. Each of the pair of mounting plates 23 is formed with a fulcrum pin hole 24 through which the rotating fulcrum pin 30 is inserted.

As shown in FIGS. 5 and 6, the attachment 31 is located at the rear end of the mixer feeder M gantry M along the forward direction Q in the forward direction Q, and is arranged on the side of the feed discharge port 12, and the gantry 2 is arranged. It is composed of an extension member 32 integrally attached to the extension member 32 in a state of projecting rearward along the forward direction Q, and a stopper body 33 integrally attached to the tip end portion (free end portion) of the extension member 32. In the stopper body 33, a pair of stopper plates 34 having a triangular shape in a plan view are integrally connected to the connecting plate 35 at predetermined intervals along the vertical direction, and the portion of the connecting plate 35. Is integrally attached to the tip end portion (free end portion) of the extension member 32. A fulcrum pin hole 36 through which the rotation fulcrum pin 30 is inserted is formed at a tip portion (free end portion) of each stopper plate 34, which is one apex of a triangular shape. A reinforcing cylindrical body 39 for reinforcing the portion is inserted and arranged in a portion where the fulcrum pin hole 36 is formed between the stopper plates 34 arranged in parallel at predetermined intervals in the vertical direction. It is integrated with each stopper plate 34.

With reference to the gantry 2 of the mixer feeder M in the pair of stopper plates 34, the outer end surface thereof is a first stopper surface 37 that determines the _{feeding inclination position (P 1) of the feeding scraper S.} Further, the inner end surface of each stopper plate 34 corresponds to the configuration in which the scraper main body 21 and the stopper plate 22 constituting the bait gathering scraper S are connected in an obtuse angle close to 180 °. Since the two different end faces are connected by forming an obtuse angle in a plan view, they are not formed on the same plane, and the end face of the two different end faces on the extension member 32 side is the bait gathering scraper S. The stopper plate 22 of the above is in contact with the second stopper surface 38 for determining _{the feeding inclination position (P 2).}

Then, as shown in FIGS. 5 to 8, each attachment plate 23 of the bait gathering scraper S is arranged outside each stopper plate 34 constituting the stopper body 33, and each fulcrum of each stopper plate 34 is arranged. By inserting the rotating fulcrum pin 30 into the pin hole 36 and the fulcrum pin hole 24 of each mounting plate 23, the bait gathering scraper S is centered on the rotating fulcrum pin 30 in the stopper body 33 of the attachment 31. Arranged rotatably. Then, as shown by the two-point chain line in FIG. 5 and the solid line in FIG. 7, the base end portion of the scraper main body 21 of the feeding scraper S is a stopper body by traveling in the backward direction R of the mixer feeder M. _{The bait gathering inclination position (P 1} ) of the bait gathering scraper S is determined by abutting on the first stopper surface 37 of the 33, and the bait gathering scraper S travels in the forward direction Q of the mixer feeder M. The stopper plate 22 abuts on the second stopper surface 38 of the stopper body 33 to determine _{the feeding inclination position (P 2) of the feeding scraper S.}

Then, at the time of feeding, as shown in FIGS. 9A and 10A, the feed F discharged from the feed discharge port 12 of the mixer feeder M is sent to the feeding tank 42 via the guide chute 13. It is supplied in a fixed amount (feeding) in a heap shape that maintains a constant width. Here, when the mixer feeder M starts traveling along the forward direction Q, the bait gathering scraper S is counterclockwise around the rotation fulcrum pin 30 due to the traveling resistance with respect to the extension surface of the bait tank floor 44. Since the rotation torque of the bait gathering scraper S always acts, the stopper plate 22 of the bait gathering scraper S is the second stopper surface 38 of the stopper body 33 attached to the gantry 2, as shown by the two-point chain line in FIG. The bait gathering scraper S is rotated counterclockwise about the rotation fulcrum pin 30 until it comes into contact with the bait, and the bait gathering scraper S runs while holding the _{feeding inclined position (P 2).} On the other hand, when the mixer feeder M is traveling backward, a clockwise rotational torque is always applied to the bait gathering scraper S around the rotation fulcrum pin 30 due to the traveling resistance with respect to the extension surface of the bait tank floor 44. The bait gathering scraper S travels while the scraper main body 21 abuts on the first stopper surface 37 of the stopper body 33 and holds the _{bait gathering inclined position (P 1) shown by the solid line in FIG.} In FIG. 7, the linear loci of the tip of the feeding scraper S at the feeding tilting position (P ₁ ) and the feeding tilting position (P ₂ ) of the feeding scraper S are shown by a one-point chain line and a two-point chain line, respectively. The position of the locus of the tip of the feeding scraper S at the feeding tilt position (P ₂ ) is the interval L with respect to the position of the locus of the tip of the feeding scraper S at the feeding _{tilt position (P 1).} It is located on the side of the rail 45. Even during feeding, the feed F spilled from the guide chute 13 toward the front side of the bait tank 42 is returned to the bait tank 42 by the bait gathering scraper S running behind the chute 13.

When the mixer feeder M reaches a slightly front side of the forward end position, the rotation of the vertical rotation shaft 5 of the auger screw 4 is stopped, the shutter 11 is lowered, and the feed discharge port 12 is closed. After that, the mixer feeder M moves forward slightly and then stops at the forward end position.

_{Before the dairy cow C ingests the feed F, the edge F 1} on the rail 45 side of the feed F supplied in a heap shape while maintaining a constant width in the feed tank 42 is shown in FIGS. 9 (a) and 9 (a) and FIG. As shown in 10 (a), it maintains a linear shape. However, after ingestion of the feed, when the feed F is ingested by the dairy cow C, the feed F is scattered, and the edge F ₂ on the rail 45 side of the scattered feed F'is shown in FIG. 9 (b). And, as shown in FIG. 10 (b), it becomes an arbitrary wavy shape.

When the dairy cow C ingests a predetermined amount of feed, that is, after the set time elapses after the mixer feeder M reaches the forward end position, the mixer feeder M starts traveling in the backward direction R by the timer. .. At the forward end position, the mixer feeder M travels in the reverse direction, and the traveling resistance of the feeding scraper S with respect to the extension surface of the feeding tank floor 44 causes the feeding scraper S to be centered on the rotation fulcrum pin 30. , The base end portion of the scraper main body 21 is automatically rotated until it comes into contact with the first stopper surface 37 of the stopper body 33, and the vehicle travels while holding _{the bait gathering inclined position (P 1).} That is, when _{changing the arrangement posture of the feeding tilting position (P 1} ) and the feeding tilting position (P ₂ ) of the feeding scraper S, the lower end edge of the feeding scraper S comes into contact with the extension surface of the feeding tank floor 44. Therefore, it is also a feature of the present invention that the two inclined arrangement positions of the feeding scraper S are automatically changed without human intervention by changing the traveling direction of the mixer feeder M in the opposite direction. It is one. As a result, as shown in FIGS. 9 (c) and 10 (c), the scatter feed F'contacts the scatter feed sliding surface 21a of the scraper main body 21 of the feed gathering scraper S traveling linearly in the receding direction R. Alternatively, after the contact, the scraper main body 21 is moved to the tip side along the scatter feed sliding surface 21a by the inclined arrangement, and is brought back to the feed tank 42. As a result, the dairy cow C can ingest the feed F together with another feed F remaining in the feeding tank 42.

In this way, the scattered feed F'over the entire length of the feeding tank 42 is automatically returned to the feeding tank 42 until the mixer feeder M returns to the starting position and stops.

If the feeding scraper S cannot be used due to the structure of the barn CH, the rotating fulcrum pin 30 may be removed and the feeding scraper S may be removed from the gantry 2.

Regarding the tip position of the feeding scraper S during the feeding work and the feeding, in the above embodiment, the tip position of the feeding scraper S during the feeding work is the interval more than the corresponding tip position during the feeding. Since only L is close to the feeding tank 42, the feeding effect is enhanced, but the position of each tip of the feeding scraper S during the feeding operation and the feeding is not limited to the above embodiment and is arbitrary.

Further, in the case of a configuration in which two barn CHs are arranged in parallel and one mixer feeding machine M running between them simultaneously feeds each feeding tank 42 of each barn CH on both sides, mixer feeding is performed. It is also possible to mount bait gathering scrapers S on both sides of the gantry 2 of the machine M to simultaneously feed the bait tanks 42.

Further, the mounting portion of the feeding scraper S on the gantry 2 of the mixer feeding machine M may be any portion as long as it does not interfere with the feeding operation, and is not limited.
