Description

  The present invention relates to a feeding apparatus, and more particularly to a feeding apparatus that enables a constant supply of roughage.

  In the breeding of animals that use roughage for feed such as cattle breeding, as shown in the flow chart of various feeds in the general feeding system shown in FIG. After being supplied and weighed by each feeding device from the storage tank and blended in the blending tank, it is fed from the shooter to a feeder consisting of a feed box or the like and fed to the domestic animals.

  However, roughage is fed raw rice straw, grass, etc. rich in crude fibers such as cellulose, or is prepared after being prepared into hay, silage, etc. In either case, rice straw, grass, etc. In order to form a nodule (see FIG. 6 showing the shape of the roughage before being supplied to the roughage feed section of the present invention), it was difficult to properly separate the roughage and to separately measure a small amount. .

  In the automatic feeding device, most of the roughage storage tanks are provided with an auger or a device for scraping the roughage inside, and the roughage is separated and taken out by a feed takeout device such as the auger or the scraping device, and is fed by a chain conveyor or a belt conveyor. It is fed out and weighed by a measuring tank and then supplied to the blending tank. However, when taking out roughage with an auger or a scraping device, it is difficult to weigh and feed the roughage of rice straw, pasture, etc. because it is sent to the weighing tank in the form of a nodule, and between the auger and the casing. The roughage was caught and the auger was often damaged.

  In addition, there is a method of using a rotating drum with claws attached as another method for removing roughage, but in this case as well, since the shape of the feed is not uniform, dropping of the bottle occurs, and it is still difficult to take out an accurate amount. (For example, see Patent Document 1).

The roughage passing through the end plate-like net 21 includes a shape bent in a V-shape, so that the rough forage of this shape is entangled with the mesh of the end plate-like net 21 in a small amount. This is because the net needs to be cleaned.

  For the attachment / detachment of the mesh frame 23, a system in which the attachment / detachment device is built in the vibrating screen 20 and is integrated with the mesh frame 23 can also be preferably used. Examples of the system that is installed in the vibrating screen 20 include a system in which the vibrating screen 20 includes a frame that encloses the mesh frame 23 and a guide that allows the mesh frame to be attached and detached. Furthermore, a method in which a hinge is provided at the end of the guide and the net frame is suspended by 90 ° can be cited as a preferred embodiment. In the case of the above method, the vibrator is fixed to a frame including the net frame 23 instead of the net frame.

The roughage supply unit is preferably provided in the lower part of the roughage tank.

  FIG. 2 is a partially cutaway perspective view of the roughage tank in which the roughage supply unit 30 is provided on the upper surface of the vibrating sieve 20 inside and under the roughage tank 10.

  In FIG. 4, the structure explanatory drawing of the said rough feed supply part 30 is shown. In FIG. 4, 31 indicates a rotating fork which is a main body portion of the roughage supply unit, 33 indicates a main shaft of the rotating fork, 35 indicates a cross bar, and 37 indicates a rotational power connecting portion of the rotating fork. A roughage not shown in the figure is supplied to the upper part of the roughage supply unit. In the present invention, the roughage is preferably chopped into 3 to 20 cm. For the shredding, any shredding method used for cutting roughage can be used.

The bar is made of a metal rod or tube having a diameter of 3 to 8 mm and a length of 3 to 10 mm, and is preferably made of a stainless steel or aluminum rod or tube like the main shaft. A plurality of cross bars 35 are mounted on the main shaft 33 at equal intervals. The interval is preferably 30 to 120 mm.

  In FIG. 5, an example of arrangement | positioning of the rotary fork of the roughage feed part 30 is shown. As shown in FIG. 5, the rotary fork 31 is preferably arranged such that the cross bar 35a of one rotary fork 31a and the cross bar 35b of the adjacent rotary fork 31b are displaced from each other in a plane. Further, it is preferable that the cross bars 35a and 35b of adjacent rotating forks are arranged so as to overlap each other by about 10 to 50 mm when viewed from the side, and the main shaft 33b of the rotating fork adjacent to the main shaft 33a of the rotating fork. Is preferably 80 to 160 mm.

  The rotational power connecting portion 37 is connected to a rotational power portion (not shown), and the rotary fork 31 performs a reciprocating motion of partial rotation by the motion of the rotational power portion.

Such an effect is prevented and the effect of enhancing the original function of the vibrating sieve is also exhibited. Furthermore, the driving of the cross bar in the upward direction also serves to prevent a sudden drop of the roughage into the lower part.

  A conveyor 50 is disposed directly below the vibrating screen and transports the dropped roughage to the weighing tank. A response control system in which the conveyor moves based on instructions from the weighing tank is preferable, and a system in which a predetermined amount of roughage is sent to the weighing tank by placing the roughage on the conveyor and moving it at a constant speed is preferable.

  The weighing tank measures the weight and / or volume of the roughage fed by the conveyor. The shape of the measuring tank is a box shape, and a structure in which the lower part is opened is preferable. In particular, the method of measuring the volume using a load cell is preferable because the apparatus is simple.

  The weighed roughage is supplied from the weighing tank to the mixing tank, mixed with other feed, and then fed into the feeder. If necessary, only the measured roughage is directly fed into the feeder.
