Description

  The present invention relates to a feed vehicle for transporting a granular material such as livestock feed mixed with corn, wheat, milo, etc., and more particularly to a structure for adding an additive to the feed.

  Conventionally, a feed storage tank, a bottom screw that is rotatably provided at the bottom of the feed storage tank, and that feeds the feed inside the feed storage tank to the rear, and is provided at the rear of the feed storage tank, 2. Description of the Related Art There is known a feed transport vehicle including a vertical transport unit that incorporates a vertical screw that transports the feed transported by a screw upward (see, for example, Patent Documents 1 and 2).

  In the feed transport vehicle disclosed in Patent Document 1, an additive screw feeder is connected to the upper and lower intermediate portions of the vertical transport portion, and the additive added to the additive hopper provided at the rear of the feed storage tank is used for the additive. While being transported by a screw feeder, it is added to the vertical transport section.

  On the other hand, in the feed carriage disclosed in Patent Document 2, an additive (additive) is added to the main feed in a vertical casing and mixed in advance with a screw, and its lower blade is rotated, It is introduced into the lower straight cylindrical discharge pipe, and the screw of the discharge screw conveyor in the discharge pipe is rotated and dropped and added to the feed (main feed) conveyed (discharged) from the discharge port of the bottom screw (floor screw conveyor) I try to let them.

  However, in the feed vehicle of Patent Document 1, it is difficult to ensure the length of the transport path after being added, that is, the length of the transport path that is transported while the additive is mixed with the feed. For this reason, there is a problem that it is difficult to sufficiently mix (uniformly mix).

  In addition, since it is added to the upper and lower middle part of the vertical transport unit, the additive hopper (input port) for adding the additive is positioned higher than that, and the additive is lifted to a higher position and charged. There must be. In other words, since the additive is usually charged in a bag or a bucket, there is a problem that it is difficult to lift and load a heavy bag or bucket if the inlet is at a high position.

  On the other hand, in the feed transport vehicle of Patent Document 2, since the additive is added from above to the bottom screw using the additive screw feeder, a part of the additive falls by its own weight and the bottom screw. It is added to the surrounding feed. Therefore, there is a problem that it is difficult to accurately adjust the additive amount. In addition, since the additive screw feeder is mounted in a vertically extending state, the inlet is inevitably at a high position, and there is a problem that it is difficult to add the additive as in Patent Document 1.

  This invention is made | formed in view of this point, The place made into the objective makes it possible to mix an additive fully (uniformly) to feed, making it the structure which is easy to throw in an additive. There is.

  In order to achieve the above object, in the present invention, the additive is added from the horizontal direction at the stage before the vertical screw.

A feed transport vehicle provided with a vertical transport unit that is provided behind the feed storage tank and contains a vertical screw that transports the feed transported by the bottom screw upward,
A screw feeder is provided to cross the bottom screw and add an additive to be added to the feed before the merging portion that feeds the feed conveyed by the bottom screw to the vertical conveyance unit.

  According to the above configuration, since the additive is fed before the merging portion that feeds the feed conveyed by the bottom screw to the vertical conveying portion, a screw feeder portion can be provided at the height of the bottom screw, The position of the additive hopper for feeding the additive into the screw feeder can also be lowered. For this reason, the addition of the additive becomes easy. In addition, the additive added to the feed is added in front of the junction where the feed that the bottom screw has transported to the vertical screw is fed, so that the additive is sufficient for the feed compared to the case where it is added to the middle of the vertical screw. Mixed in. As additives, nutrients such as amino acids and vitamins can be considered. Further, the vertical conveyance unit does not necessarily have to convey vertically, and may convey in a slightly inclined direction.

In the second invention, in the first invention,
The bottom screw has a protrusion protruding from the rear end of the feed storage tank,
The tip of the screw feeder portion is connected to a cylindrical portion surrounding the protruding portion.

  According to said structure, since the position of a screw feeder part can be lowered | hung to the position of a bottom screw, replenishment (input) and a maintenance of an additive become very easy.

In the third invention, in the first or second invention,
On the base end side of the screw feeder part,
An additive hopper for charging the additive;
An additive motor for rotating the additive screw incorporated in the screw feeder is provided.

  According to said structure, since the additive hopper part is provided in the base end side of a screw feeder part, the position of an additive hopper part can be made as low as possible.

In the fourth invention, in the third invention,
The additive motor is an electric motor directly connected to the base end of the additive screw.

  According to the above configuration, by directly connecting the electric motor to the additive screw, the height of the additive hopper can be reduced compared to the case where the electric motor is provided below as in Patent Document 1, It is easy to visually check the remaining amount of the additive, and the addition becomes easy.

  As described above, according to the present invention, the screw feeder portion for adding the additive to be added to the feed is provided in front of the merge portion for feeding the feed conveyed by the bottom screw to the vertical screw. Additives can be added to the feed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
2 to 4 show a feed transport vehicle 1 according to Embodiment 1 of the present invention. The feed transport vehicle 1 has a travelable chassis 2 and a cab 3, and the chassis 2 has a subframe 4. The feed storage tank 5 is mounted via the.

  The feed storage tank 5 is long in the front-rear direction. For example, the feed storage tank 5 is divided into four internal spaces 5a (see FIG. 1B) in the front-rear direction, and an input port cover 6 that can be opened and closed in accordance with each internal space 5a. Is provided. Each region accommodates feed mixed with, for example, nuts, wheat, pasture, corn, and milo.

  A bottom screw 7 is rotatably provided at the bottom of the feed storage tank 5 so as to extend back and forth, so that the feed in the partitioned internal space 5a can be selected and conveyed backward. . Although not shown in detail, the bottom screw 7 is rotated at a predetermined speed by driving means such as an electric motor, a hydraulic motor, and the like, and feeds stored in the internal space 5a are conveyed backward while stirring. Yes. That is, the bottom screw 7 has a spiral blade 7a that extends in a spiral shape, and feed is transported backward when rotated in one direction.

  A vertical transport unit 10 is provided behind the feed storage tank 5 so as to extend substantially vertically. Inside the vertical transport unit 10, the feed transported by the bottom screw 7 is raised vertically. The vertical screw 11 (refer FIG. 1A) to be made is incorporated. The upper side of the vertical bearing part 10 from the turning bearing part 12 can be turned by operating the turning handle 12a. In addition, you may enable it to rotate the turning bearing part 12 electrically or hydraulically.

  A discharge unit 13 containing a discharge screw (not shown) is connected to the upper portion of the vertical transport unit 10 so as to be rotatable in the vertical direction. For example, the discharge screw is rotated by a hydraulic motor or an electric motor, and the discharge unit 13 is undulated by a hydraulic cylinder 13a. By the discharge screw, the feed transported by the vertical screw 11 is transported to the tip of the discharge unit 13 and can be transferred to an insertion port such as a silo owned by a dairy farmer.

  As shown in FIG. 1A, the rear portion of the bottom screw 7 protrudes rearward from the rear surface of the feed storage tank 5 to form a protruding portion 14. The protruding portion 14 is surrounded by a cylindrical portion 14a. A joining portion 15 that bulges in the horizontal direction from the cylindrical portion 14 a is provided at a portion of the cylindrical portion 14 a that is connected to the vertical conveying portion 10. In the junction 15, the feed conveyed by the bottom screw 7 is sent out to the vertical screw 11. A tip of a screw feeder portion 20 for adding an additive to be added to the feed is connected to the cylindrical portion 14a surrounding the protruding portion 14 in front of the merging portion 15. The cylindrical part 14a is comprised, for example with the steel pipe with a flange.

  On the other hand, as shown in FIG. 1B and FIG. 5B, an additive hopper portion 21 for introducing an additive is provided on the proximal end side of the screw feeder portion 20. Further, an additive motor 22 for rotating the additive screw 20a incorporated in the screw feeder unit 20 is provided. The additive motor 22 is, for example, an electric motor that is directly connected to the additive screw 20a, and is supplied with electric power from the feed carriage 1. Thus, by directly connecting the additive motor 22 to the additive screw 20a, parts such as chains and sprockets are not required as in Patent Document 1, and the entire space, particularly the height direction space, is small. That's it. Therefore, the charging port 21a of the additive hopper 21 can be provided at a low position, and the operation of charging the additive into the charging port 21a is facilitated. In addition, the upper part of the additive hopper part 21 may be covered with the mesh part 21b for safety.

  As shown in FIGS. 5A and 5B, a manual lever 23 is provided in the front and rear of the feed storage tank 5. The manual lever 23 is used to open and close a shutter (not shown) provided in the lower portion of each internal space 5a. By adjusting the opening degree of each shutter with the manual lever 23, the manual screw 23 is moved to the bottom screw 7. The amount of feed that flows can be adjusted.

  Next, the operation of the feed transport vehicle 1 according to this embodiment will be described.

  First, in a port, a feed factory, etc., the inlet cover 6 is opened, and feed mixed with, for example, nuts, wheat, pasture, corn, milo, etc., is put into each region in the feed storage tank 5.

  Next, it moves to a silo such as a dairy farmer and supplies the feed corresponding to each silo. Specifically, the manual lever 23 is operated to open the shutter corresponding to the internal space 5a in which the feed to be supplied is accommodated, so that the feed flows down to the bottom screw 7 side.

  Subsequently, this feed is conveyed to the rear part of the feed storage tank 5 by rotation of the bottom screw 7.

  Next, the additive motor 22 of the screw feeder unit 20 is driven as the feed reaches the protruding portion 14, and the additive in the additive hopper unit 21 is mixed into the feed. As the additive, for example, an amino acid, vitamin, or other nutrient prepared in advance by a livestock farmer is mixed with the feed, and the additive motor 22 is driven in a state where the additive is put into the additive hopper unit 21. Let

  By doing so, the additive is added to the feed conveyed backward by the rotation of the bottom screw 7 in a predetermined ratio from the lateral direction, and the additive is added to the feed by the bottom screw 7 downstream from this addition position. It is conveyed backward while being mixed.

  When the bottom screw 7 is transported to the rear end in this way, it is transported to the lower end of the vertical screw 11 via the merging portion 15 and transported upward while mixing the additive by the vertical screw 11.

  At this time, also in the confluence | merging part 15, an additive is mixed in feed by the conveyance direction switching from a horizontal direction to a perpendicular direction.

  Next, while the feed and the additive are sufficiently mixed in the discharge unit 13, it reaches the tip and is supplied into a silo such as a dairy farmer.

  Thus, according to this embodiment, since the position of the screw feeder part 20 can be lowered to the position of the bottom screw 7, the supply (injection) and maintenance of additives are extremely easy.

  In this way, the additive added to the feed is added to the feed that the bottom screw 7 has transported before the junction 15 that feeds it to the vertical screw 11. For this reason, compared with the case where it adds to the upper and lower middle of the vertical screw 11, it becomes possible to ensure the conveyance path | route after being added, ie, the conveyance path | route conveyed while an additive is mixed with feed, and an additive can be ensured. It can be mixed sufficiently (evenly) in the feed.

  Further, the screw feeder 20 is provided at a height position of the bottom screw 7, and the additive motor 22 is directly connected to the additive screw 20a. For this reason, the vertical space for arranging the additive motor 22 can be suppressed, and the position of the additive hopper 21 for supplying the additive to the screw feeder 20 can be lowered. Therefore, it is easy to visually check the remaining amount of the additive, and the addition is easy.

  Therefore, according to the feed transport vehicle 1 according to the present embodiment, the screw feeder unit 20 for adding the additive to be added to the feed is provided in front of the junction 15 that feeds the feed transported by the bottom screw 7 to the vertical screw 11. Thus, the additive can be sufficiently mixed with the feed while making it easy to add the additive.

(Embodiment 2)
FIG. 6 shows Embodiment 2 of the present invention, which differs from Embodiment 1 in that the arrangement of the screw feeder 120 is different. In the present embodiment, the same parts as those shown in FIGS.

  That is, in the present embodiment, the screw feeder 120 does not extend in the horizontal direction as in the first embodiment, but is inclined upward as the additive screw 20a approaches the cylindrical portion 14a and is perpendicular to the cylindrical portion 14a. It continues to the cylindrical connecting part 120b extending in the direction. With such a configuration, the additive introduced from the insertion port 21a is sent out to the connecting portion 120b while being lifted slightly upward by the additive screw 20a, and the additive dropped from the connecting portion 120b is transferred to the bottom screw 7. It mixes with the feed which has been conveyed by the protrusion part 14. The subsequent steps are the same as in the first embodiment.

  Therefore, even if it uses the screw feeder part 120 which concerns on this embodiment, an additive can fully be mixed with a feed, setting it as the structure which is easy to throw in an additive.

  In particular, this embodiment is advantageous in that the additive can be dropped from above the bottom screw 7 without increasing the height of the additive hopper 21.

  In addition, the above embodiment is an essentially preferable illustration, Comprising: It does not intend restrict | limiting the range of this invention, its application thing, or a use.

  The above-described additive motor 22 (additive screw 20a) is rotationally driven by operating a rotation changeover switch (not shown). This rotation changeover switch is constituted by a toggle switch capable of operating a knob at a neutral (stop) position, a forward rotation position, and a reverse rotation position. For this reason, in the middle of adding the additive by operating the knob to the forward rotation position, if an additive biting failure occurs, the knob is switched to the reverse rotation position to reverse the additive motor 22. If it is rotated, the biting failure can be eliminated. Here, in the reverse rotation position, the knob is biased so as to return to the neutral position, and therefore, it is easy to perform an operation of rotating the additive motor 22 reversely by a necessary amount.
