Detailed Description of the Invention [Industrial applications]

The present invention relates to a bucket elevator, and more particularly, to a grain feeder for a bucket elevator that can feed grains at a low position.

[Prior art]

In the process of preparing and processing grains such as rice and wheat, the grains are stored in a bag as a means for temporarily storing or transporting the grains. At that time, the bag is opened and the grains are supplied to the supply unit such as the processing device. However, in order to manually supply the grains from the bag to the supply unit, the supply unit may be in a low position. desirable. Therefore, as shown in FIG. 4, a floor surface 46 is excavated to form a pit 47, and a bucket elevator 48 that conveys grains to the next step is installed in the pit 47, and the upper surface portion 49 is the same as the floor surface 46. A supply device 54 is implemented in which the discharge portion 51 of the supply hopper 50, which is a surface, is connected to the supply port 53 provided in the side surface portion 52 of the bucket elevator 48. However, this one has the advantage of omitting the force work of lifting the bag because it feeds the grains from the bag into the supply hopper 50, while it has the advantage of inspecting the lower shaft of the bucket elevator 48 or inside the pit 47. To clean the room, a lid material is placed over the pit 47.
55 must be removed, and it is difficult to inspect and work inside the pit 47. On the other hand, as shown in FIG. 5, there is a known example in which the grain conveyor capacity of the supply hopper 50 is increased and the screw conveyor 58 is provided at the inner bottom of the supply hopper 50 in order to make the pit 57 shallow. However, as with the known example described above, this also has a disadvantage in cleaning or maintenance work in the pit 57. Further, as a known example in which each of the tension hopper and the elevator is provided on the floor surface, there is a tension assist device disclosed in, for example, JP-A-59-207329. That is, a screw conveyor is horizontally installed in the hopper that is integrally formed with the cargo receiving stand, and a grain discharging port is provided on the outer peripheral side surface of the grain feeding gutter tube of the screw conveyor, and the grain discharging port and the lower supply port of the elevator are provided. Are connected via the connecting cylinder. Then, the powder loaded on the truck is moved to the loading cradle of the loading hopper, and the grains are loaded into the loading hopper from the opened bag body and horizontally fed by the screw conveyor, and the grain discharging port of the screw conveyor and The grain supplied to the elevator via the connecting cylinder is lifted and conveyed to the next process.However, in this device, the grain is restricted due to the position of the lower supply port of the elevator. Since the height of the hopper's cargo tray is determined, in order to manually squeeze the bags stacked on the floor, the bags have to be lifted up to the stool, leaving room for improvement. Met.

[Problems to be Solved by the Invention]

In any of the above-mentioned known techniques, in order to form the pit shallowly or to form the stake position of the stake hopper provided on the floor at a low position, how is the grain supply port of the bucket elevator? As shown in FIG. 4, the grain supply port 107 is opened at a position considerably higher than the lowest point of the outer peripheral turning locus A of the bucket that turns about the lower shaft. Otherwise, the grains will not flow smoothly into the bucket elevator due to natural flow. Then, this invention makes it a technical subject to provide the grain supply apparatus of the bucket elevator which can supply a grain to a grain supply hopper from a position as low as possible, without making a pit unnecessary.

[Means for Solving the Problems]

In order to achieve the above technical problems, the present invention rotatably mounts an upper shaft and a lower shaft on both side wall surfaces of a cylindrical case having a discharge port in the upper part and a supply port in the lower part, and each of the shafts is rotatable. In a bucket elevator in which a bucket belt equipped with a large number of buckets is hung between the wheeled shafts, the supply port is one side wall surface of the both side walls and is located at a position lower than the lower shaft. On the other hand, while arranging a substantially circular low wall board in the vicinity of the supply port, a plurality of wing pieces are axially mounted on a rotating shaft erected on the low wall board to form a grain transporter, The grain discharge part is provided at the upper end of the slope of the low wall board so that the supply port side of the grain carrier is provided in a slightly inclined shape and the grains are supplied in a direction orthogonal to the rotating surface of the bucket. And the supply port are connected to each other via a grain trough,
Above the bottom wall, a perforated foreign matter sorting plate is provided laterally, and a supply hopper is formed which is a partition which is erected along the peripheral wall on the upper side of the slope of the bottom wall and which is open on the lower side of the slope. The technical means has been taken such that the bottom surface of the lower side of the slope of the supply hopper serves as a supply auxiliary stand having a sloped surface that connects the floor surface and the sloped lower half of the bottom wall.

[Action and effect]

From the partition release side of the supply hopper, using the supply auxiliary base on the bottom of the supply hopper, the grains supplied on the perforated plate for foreign matter selection above the bottom wall are the grains at the upper end of the slope due to the rotating blades. It is forcibly conveyed to the grain discharge part, flows from the grain discharge part through the grain trough to the supply port of the bucket elevator, and is supplied to the bottom of the bucket elevator in the direction orthogonal to the rotating surface of the bucket. , Is immediately lifted by a large number of buckets, discharged to the grain discharge port, and supplied to the next process. Since the grain is supplied to the feed port of the grain elevator from the grain discharge part provided on the inclined high-order side of the bottom wall formed in an inclined shape, the grain supply side bottom surface of the supply hopper is used as the floor surface. It can be formed at a lower position on the floor by forming an inclined surface that connects the lower half of the bottom wall, making it easy to supply grains from the bag and to easily perform cleaning and maintenance inspections. it can.
