Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a feeder for feeding feed to cattle and other livestock, and more particularly to a feeder with a feed rate indicator capable of metering a predetermined amount of feed. is there.

[0002]

2. Description of the Related Art In dairy farming, it is preferable to accurately measure and feed a feed amount per feed to dairy cows. In addition, dairy farmers now use dairy cows with high-nutrition feeds, such as high-protein, high-calorie and high-by-protein feeds, or high-nutrition feeds, in addition to conventional feeds in order to obtain large amounts of high-quality milk. Have given. In general, for one cow, for example, 5.5 kg of a compound feed containing high protein, high calorie and a large amount of bypass protein at a time, or 5 kg of a conventional compound feed and 1.5 kg of a supplement (depending on the milk amount of the cow) The amount given is different).

The present applicant has already developed a feeder disclosed in Japanese Patent Publication No. 7-59169 for metering and feeding such kind of feed. This special fair 7
A known feeder disclosed in JP-A-59169 is provided with a feed rate indicator for indicating a feed rate of feed. And in this feeder with a feed amount indicator, on a trolley, a compound feed container containing a compound feed and a supplement container containing a supplement are mounted, and each of the compound feed container and the supplement container provided at the bottom of the supplement container is provided. By rotating the screw conveyor a predetermined number of times, the compound feed and the supplement are each confirmed by a supply amount indicator, and a predetermined amount can be supplied from each supply unit. That is, each feed in the compound feed container and the supplement container is pushed out from the outlet of each supply unit only while the screw conveyor is rotating, and each feed is pushed out when the rotation of each screw conveyor is stopped. The operation stops.
The screw conveyors for the compound feed and the supplement are stopped by performing a stop operation when the pointer of the supply amount indicator moves to a position indicating a desired supply amount.

[0004] Further, in this known feeder with a feed amount indicator, each feeding part of the compound feed container and the supplement container is provided with:
It is formed of a horizontal cylinder. The outlet of each of the supply portions is opened horizontally as it is.

[0005]

However, in the feeder with a feed amount indicator disclosed in the above-mentioned known technique (Japanese Patent Publication No. Hei 7-59169), during the operation of feeding the compound feed or the supplement, while the screw conveyor is being driven. Then, the feed is continuously and forcibly fed from the feeding section by the screw conveyor, and the driving of the screw conveyor is stopped when the pointer of the feed amount indicator reaches "0" to a desired weighing position.

However, in this known feeder with a feed rate indicator, when the screw conveyor is stopped, the feeding operation of the feed by the screw conveyor is stopped, but the outlet of the feeding section is opened laterally as it is. As a result, a part of the feed near the outlet of the dispensing section falls down from the outlet. The amount of feed that spills from the outlet of the supply unit varies depending on the weather (humidity), the properties of the feed (type and surface wetness), and the like. For example, when the outside air humidity is high or when the surface wetness of the feed particles is high, the feed particles become less slippery, and the amount of feed spilling from the outlet of the supply unit is reduced, while the outside air humidity is low or In the state where the surface wetness of the feed particles is low, the amount of feed spillage increases. Even under the same conditions, if there is no restriction on the outlet of the feed section, the amount of feed spill from the outlet of the feed section is different each time the feed is performed.

[0007] As described above, if there is a change in the feed spilling amount after the screw conveyor is stopped, the accuracy of each feed weighing becomes poor. If the amount of feed spill is constant every time, the screw conveyor may be stopped when the pointer of the supply amount indicator moves to a position smaller by the amount that allows for the amount of spill. In the feeder with the amount indicator, the desired amount cannot be fed accurately every time because the amount of spillage changes with each feeding.

[0008] Further, if the feed spills from the feeder outlet after stopping the screw conveyor in this way, the feeder must be moved after waiting for the feed to spill. In addition to the problem that the feeding time per feeding becomes long, there is also a problem that if the feed outlet is left open, the feed may spill from the feed outlet due to shaking when the feeder moves. there were.

[0009] When cattle are bred in a barn, it is presently not possible to make the passage width very large in terms of space efficiency, and the supply amount indicator disclosed in the above-mentioned known publication (Japanese Patent Publication No. 7-59169). In the attached feeder, when the course is changed in a narrow passage (for example, when turning back and forth in the same passage), the direction of the feeder is changed by grasping the steering wheel and turning back many times.

The present invention has been made in view of the above-mentioned problems of the known feeder with a feed rate indicator, and eliminates spillage of feed from an outlet of a feeding section after feeding is stopped (stopping of a screw conveyor), thereby measuring accuracy. It is an object of the present invention to provide a feeder with a feed amount indicator which can make the course higher at a fixed position and change the course when the feeder changes its traveling direction.

[0011]

The present invention has the following structure as means for solving the above-mentioned problems. The invention according to claim 1 of the present application is directed to an invention according to claim 1 in which one feed container is mounted on a movable trolley, and a screw conveyor for feeding feed is provided at the bottom of the feed container. By controlling the start and stop by the drive mechanism, the feed in the feed container is fed from the feed portion of the feed container, and the feed supply amount from the feed portion is externally displayed by the feed amount indicator. The target is a feeder with a feed rate indicator.

In the feeder with a feed amount indicator of the first aspect, one feed container is mounted on a cart. As the feed container, an appropriate container such as a compound feed, a supplement, a dried beet pulp, or a mixed coarse feed obtained by mixing beet pulp with another rough feed can be used. It is also possible to use another kind of feed (eg, supplement) in a feed container of a specific type (for example, for compound feed).

[0013] The conveyor drive mechanism is operated to start and stop by an operation lever. That is, when the operation lever is operated to the "enter" side, the screw conveyor for feeding feed is driven via the conveyor drive mechanism, and when the operation lever is operated to the "off" side, the screw conveyor is stopped. Has become.

The supply amount indicator has a structure in which the pointer moves in accordance with the driving amount of the screw conveyor. The display unit of the supply amount indicator is configured to display the feed capacity of the feed by weight. by the way,
When the type of feed is changed, the weight per the same capacity is slightly changed, and when different types of feed are replaced in one feed container, an error occurs in the display (weight display) on the supply amount indicator. . Therefore, in the feeder with a feed amount indicator, when a different type of feed is replaced in the feed container, the pointer movement amount of the feed amount indicator is adjusted according to the type of the replaced feed, or What is necessary is just to make it correspond by replacing with the display part which displayed the scale interval appropriately.

In the feeder with a feed amount indicator according to the first aspect of the present invention, the outlet of the feeding section is opened when the screw conveyor is driven and the screw conveyor is driven in conjunction with the start / stop operation of the conveyor drive mechanism.

The compound feed container 3 and the supplement container 6
Lower frame 11 and upper frame 1 of the trolley 1 respectively
2 attached. The compound feed container 3 and the supplement container 6 are each inclined downward toward the bottom as shown in FIGS. 4 and 5, and the bottom has an arc shape. In this embodiment, the compound feed container 3 is inclined downward from both sides toward the bottom, whereas the supplement container 6 has one vertical surface toward the bottom and the other inclined downward. ing. It should be noted that the feed ratio of the formula feed contained in the formula feed container 3 and the supplement contained in the supplement container 6 are different at a time (for example, 5 kg of formula feed per cow per cow,
The supplementary feed container 3 is considerably larger than the supplement container 6 because the supplement is 1.5 kg.

Screw conveyors 31 and 61 for feeding feed are provided at the bottom of the compound feed container 3 and the bottom of the supplement container 6, respectively. As shown in FIG. 6, the screw conveyors 31 and 61 are rotated by conveyor driving mechanisms 34 and 64, respectively. That is, the conveyor driving mechanism 34 for driving the screw conveyor 31 on the compound feed container side has a belt 34c with a pulley 34a provided on the reverse shaft 23d (FIG. 6) and a pulley 34b provided on the screw conveyor 31 shaft. Then, the belt 34c is tensioned by the tension device 37 so that power can be transmitted to the screw conveyor 31. Further, the tension device 37 is provided in FIG.
As shown in FIG. 3, it is operated by a wire 39 which is pulled by operating the operation lever 38. On the other hand, a conveyor drive mechanism 64 for driving the screw conveyor 61 on the supplement container side winds the belt 64c with a marginal length around a pulley 64a provided on the reverse shaft 23d and a pulley 64b provided on the shaft of the screw conveyor 61. The power is transmitted to the screw conveyor 61 by tensioning the belt 64c with the tension device 67. Further, the tension device 67 is the same as that shown in FIG.
As shown in FIG. 3, it is operated by a wire 69 pulled by operating the operation lever 68.
The conveyor drive mechanism 34 for the compound feed container-side screw conveyor 31 and the conveyor drive mechanism 64 for the supplement container-side screw conveyor 61 are provided with the respective operating levers 38, 68 in the "OFF" position, and each belt 34
c, 64c are relaxed, and the power of the reverse shaft 23d is not transmitted to the screw conveyors 31, 61.

Feeding portions 32 and 62 are provided on the outer surfaces of the compound feed container 3 and the supplement container 6 near the bottom (opposite to the screw conveyors 31 and 61). Each of the supply portions 32 and 62 has a different diameter, but a cylindrical body is used, and each of the cylindrical portions is projected laterally outward from the outer surface of each of the containers 3 and 6 to form a supply portion. ing. The supply section 62 of the supplement container 6 is installed at a higher position than the supply section 32 of the compound feed container 3.
The supplement supplied from the outlet of the supplement container supply section 62 is guided by the gutter 19 and guided to the vicinity of the exit of the supply section 32 of the compound feed container 3 as shown in FIG.

As shown in FIG. 4 and FIG. 5, a position immediately above the screw conveyor 31 in the mixed feed container 3,
In the supplement container 6, covers 33 and 63, which are bent to “H”, are provided at positions immediately above the screw conveyor 61, respectively. This each cover 3
Each of the feeders 3 and 63 is mounted so that both ends are supported on the inner wall surface of each feed container by a support tool. This each cover 3
Reference numerals 3 and 63 form a portion without a cover at a part of the length (for example, in the range of 30 to 200 mm) of the container bottom on the side of the supply portions 32 and 62. Then, each of the covers 33, 6
3, the feed in each feed container 3, 6 is
In the cover-covered portion, the screw conveyor portion enters from both sides of the cover, and in the portion without the cover, the screw conveyor portion enters from above and both sides.

The reason for providing these covers 33 and 63 is as follows.
It is as follows. That is, the amount of feed contained in each of the feed containers 3 and 6 decreases in accordance with the amount used, but when the amount of feed in the feed containers 3 and 6 changes, the weight of the feed per unit area increases. Changes near the bottom of the feed containers 3 and 6, and the packing density changes depending on the feed weight (pressure change). As described above, when the packing density of the feed near the bottom of the container changes, as the packing density increases, the feed amount of feed per rotation by the screw conveyors 31 and 61 increases. For this reason, each of the covers 33 and 63 is adopted in order to prevent the packing density near the container bottom from changing even when the amount of feed in the feed containers 3 and 6 increases or decreases in this way.

That is, when the covers 33, 63 are provided at positions immediately above the screw conveyors 31, 61, the weight of the feed above can be supported by the covers 33, 63, and the amount of feed in the feed containers 3, 6 can be reduced. Regardless of the amount, the feed density near the bottom of the container can be kept constant. Also, as described above, the cover 3
In the case where 3,63 are installed close to the screw conveyors 31,61, there is no pressure change due to the amount of feed near the bottom of the container (around the screw conveyor), but between the lower surface of the cover and the upper side of the screw conveyor. It is possible that the feed does not go around well (a space is created). In that case, there is a possibility that the amount of feed charged between each pitch of the screw conveyor varies. However, the covers 33 and 63
Since the uncovered portion is provided in a part of the supply portions 32 and 62, even if there is an unfilled portion (space portion) of feed above the blades of the screw conveyor in the cover-covered portion, the portion without the cover is provided. Will be replenished with. The length of the portion without the cover is set to such a degree that pressure does not change so much even if the amount of feed in the container increases or decreases.

The feed indicator 5 for compound feed and the feed indicator 8 for supplement have the same structure, and therefore, the feed indicator 5 for compound feed will be described below. As shown in FIGS. 6 and 15 and 16, the supply amount indicator 5 is rotated by the belt 50 (the belt 80 on the supplement supply amount indicator 8 side in FIG. 6) when the screw conveyor 31 rotates. Shaft 5
1 (81), a clutch 52 (82) provided on the shaft 51, a disk 53 (83) rotated by the clutch 52 in a horizontal attitude, and a shaft 54 of the disk 53 travels in a horizontal plane. The chain 55 includes a chain 55, a pointer 56 attached to the chain 55, and an index plate 57 for indicating a moving position of the pointer 56. The indicator plate 57 has a scale (0 to 7K) corresponding to the amount of feed supplied by the screw conveyor 31.
g) is attached. In addition, the display amount of the scale on the side of the supplement supply amount indicator 8 is smaller than that of the compound feed side supply amount indicator 5 as shown in FIG.
g).

The chain 55 is meshed with a rewinding device 59 having a built-in spiral spring. This rewinding device 59
Has the effect of returning the chain 55 to the initial position when the clutch 52 is disengaged (aligning the pointer 56 with the "0" scale of the index plate 57).

A wire 58 (a wire 88 shown in FIG. 6 or FIG. 8 on the supplement supply amount indicator 8 side) which is pulled by the drive lever 24 is attached to the clutch 52.
Are connected. And this clutch 52
Moves the drive lever 24 forward or backward in FIG.
When the wire 58 (88) is pulled to separate from the disk 53 (the clutch is disengaged) and the drive lever 24 is turned "OFF", the wire 58 is relaxed and connected to the disk 53 (operation 88). Clutch is engaged). When the clutch 52 is disengaged, the pointer 56 is automatically returned to the position of the scale "0" by the rewinding device 59.

When the drive lever 24 is turned "OFF" and the operation lever 38 (68) is turned "ON" to rotate the screw conveyor 31, the disk 53 rotates by an amount corresponding to the rotation amount. As a result, the chain 55 travels, and the hands 56 move along the index plate 57. Then, when the pointer 56 reaches a desired scale (for example, 5 kg), the operation lever 38 is turned off to stop the screw conveyor 31 and stop feeding the feed. As described above, when the supply amount indicator 5 is provided, a required amount of feed can be supplied at one time. In addition, the supply amount indicator 8 for the supplement functions in the same manner as the supply amount indicator 5 for the compound feed.

The additive container 9 accommodates additives such as calcium, phosphorus, salt, vitamins, and an additive for removing malodors in barns, and relatively small containers are employed. The additive container 9 is attached to a side surface of the supplement supply indicator 8. As shown in FIGS. 11 and 12, a screw conveyor 92 serving as an additive supply device 91 is provided at the bottom of the additive container 9. The screw conveyor 92 can be rotated by a handle 93 on the rear side of the carriage 1. On the outer surface near the bottom of the additive container 9, a supply portion 94 formed of a horizontal cylinder is formed. This supply unit 94
A funnel-shaped receptacle 95 is arranged at the outlet of the above, and the upper part of a hose 96 is connected to the lower part of the receptacle 95 in a loosely fitted state. The lower end of the hose 96 is opened above the gutter 19. And this additive supply device 91
By manually rotating the handle 93, the screw conveyor 92 can be rotated to supply the additive in the additive container 9 onto the gutter 19 through the supply unit 94, the receiver 95, and the hose 96. . The additive is added to the feed as needed, and the amount of the additive can be appropriately adjusted by the number of rotations of the handle 93.

The outlet of the supply portion 94 of the additive container 9 can be opened and closed by moving the receiver 95 up and down. That is, an opening / closing plate 99 that slides on the outlet opening surface of the supply unit 94 is provided on the supply unit 94 side of the receiver 95. This opening / closing plate 99 is shown in FIG.
As shown in (1), it is urged toward the opening side of the supply portion 94 by the coil spring 100 (two at the left and right).
As shown in FIGS. 11 and 12, two wires 98a and 98b for sliding the receiver 95 upward and downward are connected to the opening / closing plate 99, respectively. The opening / closing plate 99 is connected to the wires 98a,
An operation lever 97 provided at the rear upper portion of the feeder 98b (FIG. 1)
4 (shown also in FIG. 4), with the aid of the receptacle 95, moves up and down between an upper closed position, shown in solid lines (99) and a lower open position, shown in dashes (99 '). I am trying to get it. In addition, the opening and closing plate 9
9 is in the upper closed position, the upper edge of the opening / closing plate 99 is positioned at about half the height of the outlet of the supply portion 94. Unless the conveyor 92 is rotated, the additive does not spill out of the opening in the upper half of the outlet. In this embodiment, two wires 98a and 98b are used to operate the opening / closing plate 99, but in other embodiments,
When one of these wires is used,
A spring that biases the wire 9 in a direction opposite to the pulling direction of the wire may be used.

Incidentally, Japanese Patent Publication No. 7-5616 cited in the conventional example.
The feeder with a feed rate indicator of Japanese Patent Publication No. 9 is also provided with an additive supply device. In this known additive supply device, the supply port of the additive container is formed in a funnel-shaped slope. The supply port is opened and closed by an opening / closing plate.
However, in this known additive supply apparatus, the opening and closing plate works well when the additive is powder, but when the pellet-like additive is supplied, the opening and closing plate is closed during the closing operation of the opening and closing plate. The pellet-shaped additive may be interposed between the supply port and the supply port, in which case the supply port cannot be sufficiently closed. If the supply port cannot be sufficiently closed even when the opening / closing plate is closed in this way, there is a problem that the additive spills from the gap. However, in the additive supply device 91 according to the embodiment of the present application, the outlet of the supply unit 94 is opened laterally, and when the opening and closing plate 99 is closed, the opening and closing plate 99 closes the outlet of the supply unit 94 approximately. Since only about half the height is closed, the additive does not get caught in the outlet part of the supply part, and even if the outlet part is closed only about half the height, the supply part 94 is horizontal. The additive does not spill from the outlet of the supply section. Therefore, in the additive supply device 91 of the embodiment of the present application, even the pellet-shaped additive can be used without any trouble.

The feed units 32 and 62 of the feed containers (mixed feed container 3 and supplement container 6) are provided with feed unit opening / closing devices 4 and 7 for opening and closing the feed unit outlets, respectively. I have. The feeder opening / closing device 4 on the side of the compound feed container 3 and the feeder opening / closing device 7 on the side of the supplement container 6 are different in size but have the same structure. The outlet opening / closing device 4 will be described.

The feeder opening / closing device 4 on the side of the compound feed container 3 is
As shown in FIGS. 9 and 10, the opening / closing plate 42 can be slid up and down by two wires 41 a and 41 b on the front surface of the outlet of the supply portion 32. The open / close plate 42 has a semicircular shape with a horizontal upper side. On the upper side of the opening / closing plate 42, an inclined surface 42a which is inclined downward and outward is formed. Sleeves 47 are fixed to left and right ends of the open / close plate 42, respectively. These sleeves 47, 47 have connecting members 48, 4 respectively.
The shafts 44, 44 attached to 8 are rotatably inserted. Further, rocking arms 43, 43 are loosely inserted into the center portions of the connecting members 48, 48, respectively. The rear ends of the rocking arms 43 are fixed to sleeves 45a, 45a rotatably fitted to both ends of one common shaft 45, respectively. The sleeves 45a, 45a are connected by a connecting member 49, so that the swing arms 43, 43 are integrally linked. Also, one sleeve 45
A protruding bar 43a extending in the direction of the extension of the rear end side of the swing arm 43 is fixed to a. And these rocking arms 43, 4
Numeral 3 is swingable up and down around a shaft 45. By swinging the swing arms 43 and 43 up and down, the connecting members 48 and 48 and the shafts 44 and 44 are used. The opening / closing plate 42 can be moved up and down. The opening / closing plate 42 is urged toward the outlet side of the supply portion 32 by two coil springs 46, 46 on the left and right sides.

The ends of two wires 41a and 41b are connected to one swing arm 43 and the protruding rod 43a at equidistant positions on both sides of the shaft 45. The other ends of the wires 41a and 41b are, as shown in FIG.
Each of the wires 41a and 41b can be selectively pulled (the other wire can be extended) by operating the operation lever 38. Then, the operation lever 38 is turned on in FIG.
In the state, the swing arm 43 is in the state shown by the solid line in FIG.
When the operation lever 38 is operated to the right “OFF” side from the state of FIG.
At the same time as the wire on the side is pulled, the wire denoted by reference numeral 41b is extended, and the swing arm 43 swings as shown by a chain line in FIGS.
As shown by, the actuator is displaced to the upward closing position.
Also, when the operation lever 38 is operated to the left “enter” side from the state where the opening / closing plate 42 is in the upwardly closed position shown by the dashed line, the wire indicated by reference numeral 41b is pulled at the same time as the wire indicated by reference numeral 41b is pulled. The wire extends, and the swing arm 43 swings from the state shown by the dashed line in FIGS. 9 and 10 as shown by the solid line, whereby the opening / closing plate 42 is displaced to the lower movement open position as shown by the solid line.

As in the case of the opening / closing plate 99 on the additive container 9 side, either one of them can be a spring.

The feeding unit opening / closing device 4 on the side of the compound feed container 3 is
The operation is shared by the operation lever 38 of the screw conveyor 31 on the compound feed container side. That is, when the operation lever 38 is operated to the drive side ("in" side) of the compound feed container side screw conveyor 31, the opening / closing plate 42 of the supply / reception unit opening / closing device 4 is displaced from the upwardly closed state to the downwardly opened state. On the other hand, when the operation lever 38 is operated to the stop side ("off" side) of the screw conveyor 31, the opening / closing plate 42 is displaced from the downward open state to the upward closed state. Therefore, one operating lever 3
By the “in” and “off” operations of 8, the start of driving the screw conveyor 31 and the opening operation of the opening and closing plate 42 are performed simultaneously, while the stop of the screw conveyor 31 and the closing operation of the opening and closing plate 42 are performed simultaneously.

The feeding unit opening / closing device 7 on the supplement container 6 side is also configured in the same manner as the feeding unit opening / closing device 4 on the compound feed container 3 side, and starts and stops the screw conveyor 61 on the supplement container 6 side. The opening / closing operation of the feeding unit opening / closing device 7 on the supplement container 6 side can be performed by one operation lever 68 as in the case of the compound feed container 3 side.

The opening / closing device 4 on the side of the compound feed container 3 and the opening / closing device 7 on the side of the supplement container 6 have the following functions. Since the functions of the two feeder opening / closing devices 4 and 7 are the same, the feeder opening / closing device 4 on the side of the compound feed container 3 will be described.

First, when the operation lever 38 is operated to the "in" side shown in FIG. 13 in a state where the engine 21 is driven, the screw conveyor 31 rotates and the feeding / opening / closing device 4 is opened.
Of the compound feed container 3
The mixed feed is continuously supplied from the outlet through the supply section 32. At this time, when the pointer 56 of the feed feed indicator 5 moves in accordance with the rotation amount of the screw conveyor 31 (the feed amount of the feed feed), and the pointer 56 reaches a desired scale (for example, 5 kg). Then, the operation lever 38 is turned off. Then, the wire 39 is loosened, and the belt 34 is loosened.
At the same time as the rotation of the screw conveyor 31 is stopped due to the relaxation of the wire c, the wire 41a on the side of the feeder opening / closing device 4 is pulled, and the opening / closing plate 42 is indicated by a chain line in FIG. 9 and FIG. It moves upward to a position where the lower half of the outlet of the supply section 32 is closed. Therefore, immediately after the screw conveyor 31 stops, the outlet of the feeding section 32 can be closed immediately, and at that time, the feed can be prevented from spilling from the outlet of the feeding section. In addition, the supplement feeding unit opening / closing device 7 can also open and close the opening / closing plate 72 in conjunction with the start / stop operation of the screw conveyor 61 by another operation lever 68. It has the same function as the device 4.

In this embodiment, the opening / closing plate 42 is configured to close only the lower half of the supply unit outlet when the supply unit outlet is closed. In the vicinity of the outlet of the supply section 32, the feed is at a height indicated by the symbol S in FIG. 10, and the opening / closing plate 42 can sufficiently prevent the feed from spilling. In another embodiment, the area of the opening / closing plate 42 may be set to be equal to the opening area of the outlet of the supply unit, and the entire area of the outlet of the supply unit may be closed by the opening / closing plate 42. .

As described above, the feeder opening / closing devices 4 and 7 can open / close the opening / closing plates 42 and 72 in conjunction with the start / stop operations of the screw conveyors 31 and 61. Immediately after the stop (after the feed supply is stopped), the outlet of the feed section can be automatically closed, and the drop of the feed after the screw conveyor is stopped can be prevented. Therefore, the amount of feed weighed by the feed amount indicators 5 and 8 is supplied per one feeding operation, and the weighing accuracy is improved.
Further, since it is not necessary to wait for the time when the feed falls after feeding is stopped, it is possible to move to the next feeding place immediately after the feeding stop operation, and time is not lost. Also, when moving the feeder,
Each feeding part 3 of the compound feed container 3 and the supplement container 6
Since the feeders 2 and 62 are closed by the open / close plates 42 and 72, respectively, the feed does not fall down from the outlets of the feed sections 32 and 62 even if the feeder shakes during movement.

By the way, when cattle are bred in a barn, it is the present situation that the passage width cannot be made so large in terms of space efficiency. Conventionally, the course of a traveling type feeder is changed in a narrow passage. In the case of doing (for example, when turning back and forth in the same passage), the direction of the feeder was changed by holding the handle and turning repeatedly. In view of such circumstances, in the present application, the carriage 1 is equipped with the traveling direction changing device 10 so that the course can be changed at a substantially fixed position at the time of changing the traveling direction of the feeder.

As shown in FIGS. 17 to 19, the traveling direction changing device 10 includes a front wheel turning mechanism 15 for changing the directing direction of each of the front wheels 13, 13, and a bogie 1 with respect to the ground at the rear corner. An auxiliary wheel 16 which can be freely attached and detached,
And a jack device 17 mounted near the center of the lower surface of the bogie. In this embodiment, the front wheels 13, 13 correspond to the left and right wheels in claims 1 and 2, the rear wheel 14 also corresponds to the middle wheel, and the front wheel turning mechanism 15 also corresponds to the wheel turning. It corresponds to the direction mechanism.

The front wheel turning mechanism 15 is, as described above,
The steering direction of the front wheels 13, 13 can be changed by rotating the handle 151 in the left or right direction.

The auxiliary wheels 16 are attached to the lower frame 11 of the trolley 1.
At the rear right corner, the hinge 161 is vertically pivotably mounted between an upper storage position shown in FIG. 17 and a lower use position shown in FIG. In this embodiment, the center of gravity of the entire feeder is set on the bogie 1 because the heavy engine 21 is installed near the rear right corner in FIG.
In this case, it is preferable to provide the auxiliary wheel 16 at the right corner of the rear part of the bogie. The auxiliary wheels 16 are set such that the lower surface of the auxiliary wheels slightly touches or approaches the ground when the auxiliary wheels 16 are lowered to the use position, and two front wheels 13 and 13 and one rear wheel 14 are provided. It is preferable that the auxiliary wheel 16 can be freely moved up and down in the state where the three points are supported by the above.
The auxiliary wheel 16 is set so as to be directed at right angles to a line connecting the auxiliary wheel 16 and the jack device 17 when the auxiliary wheel 16 is lowered to the use position, as shown in FIG. The method of attaching the auxiliary wheel 16 is as follows:
May be slid up and down with respect to each other, and may be locked by a suitable means at a storage position separated from the ground and a use position contacting (or approaching) the ground.

In this embodiment, the jack device 17 uses a hydraulic cylinder, and a hydraulic pump 18 mounted on the carriage 1.
The cylinder is expanded and contracted by hydraulic oil pressure from the engine (driven by the engine 21). The jack device 17 may be a foot-operated hydraulic cylinder or other general-purpose jack. The jack device 17 is mounted near the center of the lower surface of the bogie 1 at a position away from the center of gravity of the feeder and on the side opposite to the auxiliary wheels. That is, the center of gravity of the feeder is the lower front wheel (right front wheel) 1 in FIG.
It is located at a position close to the jack device 17 within a triangle connecting the 3, the auxiliary wheel 16 and the jack device 17.

The traveling direction changing device 10 is used as follows. For example, when making a U-turn in a passage in a cowshed, first, the front wheels 13, 13 and the rear wheel 14 are grounded, and the front wheels 13, 13 are moved in the direction shown in FIG. 17 in a direction perpendicular to the line connecting them. Next, the auxiliary wheel 16 is grounded, and then the jack device 17 is extended to ground and lift. Then, due to the position of the center of gravity of the feeder, the left front wheel 13 and the rear wheel 14 rise as shown in FIG. 18, and the feeder can be supported at three points by the jack device 17, the right front wheel 13 and the auxiliary wheel 16. Then, in this state, if the feeder is rotated clockwise or counterclockwise by a required angle manually, the feeder can be turned around the ground contact portion of the jack device 17 lightly. In this way, when the traveling direction of the feeder is changed, by rotating the feeder 1 around the jack contacting portion near the center of the truck 1, the feeder can be changed in direction substantially at the fixed position. When the direction changing operation is completed, the jack device 17 may be reduced to bring the left front wheel 13 and the rear wheel 14 into contact with the ground, and then the auxiliary wheel 16 may be moved upward and stored in the cart 1.
