Description

  The present invention relates to a technique for feeding livestock such as cattle, and in particular, an automatic feed device suitable for gathering food that has been scattered by a livestock in a barn to a breeding area while automatically stirring the food. It is about.

  2. Description of the Related Art Conventionally, livestock such as cattle is housed in a breeding area provided in a barn and eats feed fed along the outer periphery of the breeding area. In this case, even if there is food left over from the previous time, new food is placed on the top and fed. However, livestock such as cows have a high palatability, and they have the habit of eating old and disliked foods by skipping them far away with their noses and tongues and choosing fresh or favorite foods. For this reason, conventionally, the scattered food must be manually returned or gathered to the breeding area using heavy equipment such as bulldozers, mixed with new food, and fed, which is a burden on the breeder. . Moreover, since the amount of milk is reduced if the cow skips the food and cannot eat it sufficiently, it is preferable to collect the scattered food and eat it, regardless of the regular feeding time. Especially when a cow eats food, the new food will be thrown together with the momentum.

  As a technique for solving such a problem, for example, a feeding facility described in JP-A-11-89470 has been proposed (Patent Document 1). This feeding facility has a guide rail installed on the ground along the outer periphery of the breeding area, and has a moving vehicle that travels along this guide rail.

  Next, the operation of the automatic feeding device 1 according to this embodiment will be described with reference to the drawings.

  First, when the automatic feeding device 1 of the present embodiment gathers the food B scattered far from the outer periphery of the breeding area A to the breeding area A side, the control means 6 has a predetermined operation schedule based on a preset operation schedule. Start on time. Before the work starts, the automatic bait feeder 1 stands by with the bait feeder 4 raised to the work start position of the guide rail 7 as shown in FIG.

  Next, the control means 6 drives the arm drive part 34, and lowers it to such an extent that the bait guard part 42 of the bait gathering means 4 does not contact the ground. Then, the upper arm 31 and the lower arm 32 are swung around the vertical swing shaft 51 by driving the helical shaft motor 54 and applying torque to the vertical swing shaft 51. Thereby, the bait gathering means 4 is smoothly turned without contacting the ground, and the distance and angle with the outer peripheral part of the breeding area A are easily adjusted.

  In this embodiment, since the angle of the bait-feeding means 4 with respect to the vertical arm 33 is fixed in advance, the angle of the bait-feeding means 4 is adjusted by the vertical swinging means 5, but this is not limited thereto. Instead, it may be rotated around the connecting shaft 41 by a predetermined drive source, and the angle may be set appropriately.

  After determining the position for bait B by turning the bait gathering means 4, the control means 6 drives the arm drive unit 34 again, and the bait guard unit 42 contacts the ground as shown in FIG. 9B. Until then, the bait-feeding means 4 is lowered and deployed at the work start position. Then, the stirring motor 44 is driven to start rotating the screw auger 43a around the horizontal rotation shaft 43b, and the driving motor 23 is driven to move the moving means 2 along the guide rail 7. Thereby, the bait gathering means 4 moves in the arrow direction of FIG.9 (b) in the position which left | separated from the outer peripheral part of the breeding area A a little.

  While the bait-feeding means 4 is moving, the screw auger 43a easily gathers the bait B scattered far away from the outer periphery of the breeding area A to the breeding area A side and agitate the outer periphery of the breeding area A. Also mixed with bait B having high palatability near the head. Thereby, since it becomes difficult for livestock to select the food B, the food B is evenly ingested without unevenness, and the food B with poor palatability is not rotted and wasted.

  The bait B on the ground that has passed through the lower part of the screw auger 43a is scraped by the scraper 45 and collected in the accommodation space of the bait guard part 42 so as not to spill behind it. Thereby, even if it is the powdery bait B and the grass about 30-100 mm in length, it is scraped up with few leaks. The bait B accommodated in the bait guard section 42 is swept toward the breeding area A as the automatic bait feeder 1 moves because the bait feeding means 4 is fixed at an acute angle with respect to the guide rail 7. .

  Thereafter, as shown in FIG. 9C, when the automatic bait feeder 1 moves to the work end position, the stop sensor 71 provided on the guide rail 7 corresponding to the position outputs a stop signal. The control unit 6 that has received the stop signal at the receiving unit 61 stops the driving motor 23 to stop the moving unit 2, stops the stirring motor 44, and stops the rotation of the screw auger 7. Then, the arm driving unit 34 is driven to raise the bait collecting means 4 to such an extent that the bait guard unit 42 is separated from the ground, and then the helical shaft motor 54 is driven to vertically swing the upper arm 31 and the lower arm 32. It is swung around the moving shaft 51 and brought to the breeding area A side.

  Subsequently, the control means 6 drives the arm drive unit 34 again, raises the bait-feeding means 4 via the vertical arm 33, and is raised to the head of the livestock through a trajectory where the bait-feeding means 4 does not hit the livestock. The

  Finally, the control unit 6 drives the drive motor 23 to move the moving unit 2 in the reverse direction along the guide rail 7 as shown in FIG. And if the automatic bait feeder 1 moves to the initial position shown to Fig.9 (a), the stop sensor 71 installed on the guide rail 7 corresponding to the said initial position will output a stop signal. The control means 6 that has received the stop signal at the receiving unit 61 stops the drive motor 23 and stops the moving means 2.

  As described above, the control means 6 can automatically repeat the above-described series of operations based on the operation schedule arbitrarily set by the user.

According to this embodiment as described above,
1. The food B with poor palatability scattered by the livestock can be easily gathered to the breeding area A side while stirring and mixing with the food B with good palatability, and the food B can be eaten evenly without waste.
2. Since it is automatically driven regularly even at night, the burden on the breeder can be reduced and the milk yield of livestock can be increased.
3. Injuries and accidents due to contact between the device and livestock can be prevented, and the safety of livestock can be ensured.
4). There is no need to install guide rails on the ground in the barn, and it can be kept in the stored state except during work, so it does not get in the way, heavy machinery etc. can be put in the barn, or other work is easy The effect of.
